ACTION: Proposed rule. AGENCY: We, the Office of Surface Mining Reclamation and Enforcement (OSMRE or OSM), are proposing to revise our regulations, based on, among other things, advances in science, to improve the balance between environmental protection and the Nation’s need for coal as a source of energy. This proposed rule would better protect streams, fish, wildlife, and related environmental values from the adverse impacts of surface coal mining operations and provide mine operators with a regulatory framework to avoid water pollution and the long-term costs associated with water treatment. We propose to revise our regulations to clearly define ‘‘material damage to the hydrologic balance outside the permit area’’ and require that each permit specify the point at which adverse mining-related impacts on groundwater and surface water would reach that level of damage; collect adequate premining data about the site of the proposed mining operation and adjacent areas to establish an adequate baseline for evaluation of the impacts of mining and the effectiveness of reclamation; adjust monitoring requirements to enable timely detection and correction of any adverse trends in the quality or quantity of surface water and groundwater or the biological condition of streams; ensure protection or restoration of perennial and intermittent streams and related resources; ensure that permittees and regulatory authorities make use of advances in science and technology; ensure that land disturbed by mining operations is restored to a condition capable of supporting the uses that it was capable of supporting before mining; and update and codify the requirements and procedures for protection of threatened or endangered species and designated critical habitat. The proposed changes would apply to both surface mines and the surface tkelley on DSK3SPTVN1PROD with PROPOSALS2 SUMMARY: VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 effects of underground mines.

Executive Summary Significant advances in scientific knowledge and mining and reclamation techniques have occurred in the more than 30 years that have elapsed since the enactment of the Surface Mining Control and Reclamation Act of 1977 (SMCRA or the Act) 1 and the adoption of federal regulations implementing that law. The proposed rule seeks to acknowledge the advancements in science, technology, policy, and the law that impact coal communities and natural resources, based on our experience and engagement with state regulatory authorities, industry, nongovernmental organizations, academia, citizens, and other stakeholders. The primary purpose of this proposed rule is to reinforce the need to minimize the adverse impacts 2 of surface coal mining operations on surface water, groundwater, fish, wildlife, and related environmental values, with particular emphasis on protecting or restoring streams and aquatic ecosystems. The proposed rule, if adopted as final, also will enhance public health by reducing exposure to contaminants from coal mining in drinking water. The proposed rule has the following seven major elements: • First, the proposed rule defines the term ‘‘material damage to the hydrologic balance outside the permit area’’ and requires that each permit establish the point at which adverse mining-related impacts on groundwater and surface water reach an unacceptable level; i.e., the point at which adverse impacts from mining would cause material damage to the hydrologic balance outside the permit area. • Second, the proposed rule sets forth how to collect adequate premining data about the site of the proposed mining operation and adjacent areas to establish a comprehensive baseline that will 1 30 U.S.C. 1201 et seq. include loss of headwater streams, longterm degradation of water quality in streams downstream of a mine, displacement of native species, fragmentation of large blocks of mature hardwood forests, compaction and improper construction of postmining soils that inhibit the reestablishment of native plant communities and adverse impacts on watershed hydrology where coal mining occurs. 2 Impacts E:\FR\FM\27JYP2.SGM 27JYP2 tkelley on DSK3SPTVN1PROD with PROPOSALS2 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules facilitate evaluation of the effects of mining operations. • Third, the proposed rule outlines how to conduct effective, comprehensive monitoring of groundwater and surface water during and after both mining and reclamation and during the revegetation responsibility period to provide realtime information documenting miningrelated changes in water quality and quantity. Similarly, the proposed rule addresses the need to require monitoring of the biological condition of streams during and after mining and reclamation to evaluate changes in aquatic life. Proper monitoring would enable timely detection of any adverse trends and allow timely implementation of any necessary corrective measures. • Fourth, the proposed rule promotes the protection or restoration of perennial and intermittent streams and related resources, especially the headwater streams that are critical to maintaining the ecological health and productivity of downstream waters. • Fifth, the proposed rule is intended to ensure that permittees and regulatory authorities make use of advances in information, technology, science, and methodologies related to surface and groundwater hydrology, surface-runoff management, stream restoration, soils, and revegetation, all of which relate directly or indirectly to protection of water resources. • Sixth, the proposed rule is intended to ensure that land disturbed by surface coal mining operations is restored to a condition capable of supporting the uses that it was capable of supporting before mining. Soil characteristics and the degree and type of revegetation have a significant impact on surface-water runoff quantity and quality as well as on aquatic life and the terrestrial ecosystems dependent upon perennial and intermittent streams. The proposed rule also would require revegetation of reclaimed minesites with native species unless and until a conflicting postmining land use, such as intensive agriculture, is implemented. • Seventh, the proposed rule would update and codify requirements and procedures to protect threatened and endangered species and designated critical habitat under the Endangered Species Act of 1973.3 It also would better explain how the fish and wildlife protection and enhancement provisions of SMCRA should be implemented. This proposed rule would more completely implement SMCRA’s permitting requirements and performance standards, provide regulatory clarity to operators and stakeholders while better achieving the purposes of SMCRA as set forth in section 102 of the Act.4 In particular, the proposed rule would more completely realize the purposes in paragraphs (a), (c), (d), and (f) of that section, which include establishing a nationwide program to protect society and the environment from the adverse effects of surface coal mining operations and assuring that surface coal mining operations are conducted in an environmentally protective manner and are not conducted where reclamation is not feasible. Furthermore, the proposed rule is intended to address recent court decisions, mitigate legal challenges, and strike the appropriate balance between environmental protection, agricultural productivity and the Nation’s need for coal as an essential source of energy, while providing greater regulatory certainty to the mining industry. Apart from the procedural determinations in Part XIII, this document does not discuss the benefits and costs of the proposed rule in detail. Please refer to the draft regulatory impact analysis for an in-depth analysis of projected benefits and costs of the proposed rule and other alternatives under consideration. and adverse impacts on fish, wildlife, and related environmental values and to achieve enhancement of those resources where practicable.6 It also would update our regulations concerning compliance with the Endangered Species Act of 1973.7 In addition, we propose to revise and reorganize our regulations for clarity, to make them more userfriendly, to remove obsolete and redundant provisions, and to implement plain language principles. Coal mining operations continue to have adverse impacts on streams, fish, and wildlife despite the enactment of SMCRA and the adoption of federal regulations implementing that law more than 30 years ago. Those impacts include loss of headwater streams, longterm degradation of water quality in streams downstream of a mine, displacement of pollution-sensitive species of fish and insects by pollutiontolerant species, fragmentation of large blocks of mature hardwood forests, replacement of native species by highly competitive non-native species that inhibit reestablishment of native plant communities, and compaction and improper construction of postmining soils that result in a reduction of site productivity and adverse impacts on watershed hydrology. II. Why are we proposing to revise our regulations? Our primary purpose in proposing this rule is to strike a better balance between ‘‘protection of the environment and agricultural productivity and the Nation’s needs for coal as an essential source of energy.’’ 5 Specifically, the proposed rule is designed to minimize the adverse impacts of surface coal mining operations on surface water, groundwater, and site productivity, with particular emphasis on protecting or restoring streams, aquatic ecosystems, riparian habitats and corridors, native vegetation, and the ability of mined land to support the uses that it was capable of supporting before mining. Our proposed changes reflect our experience during the more than three decades since adoption of the existing regulations, as well as advances in scientific knowledge and mining and reclamation techniques during that time. The proposed rule would more completely implement sections 515(b)(24) and 516(b)(11) of SMCRA, which provide that, to the extent possible using the best technology currently available, surface coal mining and reclamation operations must be conducted to minimize disturbances Impacts on Aquatic Ecology Headwater streams consist of firstorder through third-order streams 8 under the Strahler stream-order system, which is the generally-accepted geographical classification system for ranking streams by size.9 Headwater streams are the small swales, creeks, and streams that connect to form larger streams and rivers. They trap floodwaters, recharge groundwater, remove pollution, provide fish and wildlife habitat, and sustain the health of downstream rivers, lakes, and bays. These streams support diverse biological communities of aquatic invertebrates, such as insects, and 4 30 3 16 U.S.C. 1531 et seq.

A first-order stream has no tributaries. When two first-order streams join, they form a second-order stream. When two secondorder streams join, they form a third-order stream. 7 16 E:\FR\FM\27JYP2.SGM 27JYP2 44440 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules tkelley on DSK3SPTVN1PROD with PROPOSALS2 vertebrates, including fish and salamanders, that are often distinct from the species found further downstream. Headwater streams function as sources of sediment, water, nutrients, and organic matter for downstream systems. Riparian vegetation provides organic matter to headwater streams in the form of dropped leaves and other plant parts. This organic matter fuels the aquatic food web.10 According to the U.S. Environmental Protection Agency (EPA), headwater streams that flow only seasonally or in response to precipitation events; i.e., intermittent and ephemeral streams, comprise approximately 53 percent of the total stream miles in the continental United States.11 Headwater streams are the streams most likely to be directly disturbed or impacted by coal mining activities. The EPA estimates that SMCRA permits in existence between 1992 and 2002 authorized the destruction of 1,208 miles of headwater streams.12 This total included approximately 2 percent of the total stream miles and 4 percent of the first-order and second-order stream miles in the central Appalachian coalfields.13 Our proposed rule would address loss of stream miles in two ways. First, we propose to amend the standards governing excess spoil and coal mine waste to minimize both the generation of excess spoil and the placement of excess spoil and coal mine waste in perennial or intermittent streams. Second, we propose to adopt standards that would minimize mining through perennial and intermittent streams. When mining through a perennial or an intermittent stream does occur, our revised standards would require that the permittee restore both the hydrological form and the ecological function of the mined-through stream segment. Midwestern studies of reconstructed stream segments demonstrate that restoration of hydrological form and ecological function after mining through a stream is technologically feasible and attainable. In Illinois, case studies documented that streams flowing through channels reconstructed after mining can approach the regional biological diversity found in streams in unmined watersheds in that region.14 Another Illinois study focused on 25 miles of low-gradient perennial streams with moderately disturbed premining watersheds. Those stream segments were relocated in the 1980s to facilitate mining and then were restored in their approximate premining location, although two of the three streams were routed through permanent pit impoundments for part of their length. In general, the study found that the premining hydrological form and ecological function of the streams have been successfully restored, based on a comparison with relatively undisturbed segments of those streams that are upstream of the mining operations.15 The exception is fish abundance and diversity, which is substantially lower, perhaps, the authors suggest, because of the lack of mature riparian timber and instream woody debris.16 In addition, monitoring of habitat, water chemistry, and biological parameters of a lowgradient stream in Indiana that flows through a channel reconstructed after mining has demonstrated rapid recovery of the stream’s ecological function.17 The general consensus is that reconstruction and restoration of highgradient streams after mining is more challenging. However, a 2012 EPA publication notes that ‘‘restoration of high-gradient, very small intermittent and ephemeral channels as part of stream mitigation projects is common in 10 Palmer, Margaret A. and Emily S.

In some cases, the permittee may have decided not proceed with mining or to alter mining plans subsequent to permit issuance.

Appendix B of the publication describes a scenario in which high-gradient stream channels devoid of aquatic life on an abandoned minesite in West Virginia may be restored to biological health in an estimated 10 years.19 Most adverse impacts of surface coal mining operations on water quality occur as a result of the excavation and fracturing of the rock layers above the coal seam. The mining process converts mostly solid rock, which has few pore spaces and thus offers little opportunity for chemical reaction with air and water, into highly fragmented mine spoil, which contains a vastly greater number and volume of pore spaces and thus offers much greater opportunity for chemical reaction with air and water. Surface water and groundwater infiltrate the pore spaces in mine spoil placed in the backfilled area of a mine or in an excess spoil fill and react with air and the surfaces of the rock fragments to produce drainage with high ionic concentrations. Specifically, water percolating through an excess spoil fill or the backfilled area of a mine typically contains substantially higher concentrations of sulfate, bicarbonate, calcium, and magnesium ions, as well as some trace metals, compared to the concentrations of those ions and metals in groundwater discharges and surface runoff from areas undisturbed by mining.20 18 Harman, W., R.

The researchers state that typical specific conductance levels in low order streams in West Virginia range from 13 to 253 microSiemens per centimeter (mS/cm). Specific conductance levels in streams impacted by mining range from 502 to 2,540 mS/cm. (Specific conductance is a measure of electrical conductivity. High specific conductance readings are a strong indicator of land disturbance, such as agriculture, urbanization, or mining. See Pond, G.J., M.E. Passmore, F.A. Borsuk, L. Reynolds, and C.J.

Elevated concentrations of alkaline ions in mine drainage may result in significant increases in the pH and electrical conductivity of streams that receive discharges from mined areas.23 Elevated concentrations of both these ions and sulfate ions are highly correlated with elevated electrical conductivity in streams, which is highly correlated with the loss or absence of pollution-sensitive species of aquatic insects and fish even when in-stream habitat downstream of the mining activity is otherwise intact.24 The adverse impacts may extend far downstream. One study found that adverse impacts from both surface and underground mines on water quality in Appalachian streams extended an average of 6.2 miles downstream from the mine.25 The EPA has established an aquatic life benchmark of 300 microsiemens per centimeter (mS/cm) for electrical conductivity, based on a scientific determination that maintaining conductivity at or below this level should prevent the extirpation of 95 percent of invertebrate genera, such as mayflies, dragonflies, damselflies, and aquatic beetles, in central Appalachian streams.26 In other words, mining conditions using family- and genus-level macroinvertebrate bioassessment tools.

A recent study suggests that a similar benchmark for fish would be somewhat higher because adverse impacts on the populations and diversity of fish species begin to appear at conductivity readings between 600 and 1,000 mS/cm.27 Elevated electrical conductivity in streams can persist for many years after the completion of mining and land reclamation.28 This water quality characteristic can prevent or restrict recolonization by the species of fish 29 and insects 30 that inhabited the affected stream segment before mining began in the watershed. Studies in Appalachia of existing minesites have not found any ecologically significant improvement in electrical conductivity with either time or the extent of reforestation of the minesite.31 However, a recent study of test plots on a surface mine in Kentucky found that the quality of water emanating from plots that used the Forestry Reclamation Approach 32 to Washington, DC.

EPA further states that this benchmark also may be appropriate for other nearby regions, but that it may not apply when the relative concentrations of dissolved ions are different. 27 Hitt, N.P. and D.B.

These steps are: (1) Prepare a suitable growth medium, (2) minimize compaction, (3) minimize competition from groundcover, (4) plant early- and late-successional tree species, and (5) use proper tree-planting techniques.

Selenium Impacts In locations with geological formations that contain selenium, mining has sometimes resulted in elevated levels of selenium in streams downgradient of the minesite. Mining exposes elemental selenium to air, thus facilitating oxidation to selenite and selenate, which are soluble in water. Selenium bioaccumulates 34 in fish tissues, causing reproductive problems, physical deformities, and, in extreme cases, mortality in fish in the affected streams.35 Selenium is beneficial to animals, including humans, when ingested in small amounts, but toxic when ingested in amounts ranging from 0.1 to 10 mg/kg of food.36 Humans have a dietary requirement estimated to be 0.04 to 0.10 mg/kg of food, but ingestion of selenium in amounts as low as 0.07 mg per day has been shown to have deleterious effects similar to arsenic poisoning.37 Thus, selenium concentrations in streams may be a human health concern when the stream serves as a drinking water supply or 33 Sena, Kenton L., ‘‘Influence of Spoil Type on Afforestation Success and Hydrochemical Function on a Surface Coal Mine in Eastern Kentucky’’ (2014).

Electrical conductivity during the first 3 years averaged between 829 and 1224 mS/cm, depending upon whether the soil consisted of brown sandstone, gray sandstone, or a mix. Electrical conductivity in the last year of the study averaged between 421 and 564 mS/cm. 34 Bioaccumulation means an increase in the concentration of a chemical in a biological organism over time, compared to the chemical’s concentration in the environment. Compounds accumulate in living things any time they are taken up and stored faster than they are broken down (metabolized) or excreted. See extoxnet.orst.edu/ tibs/bioaccum.htm (last accessed January 6, 2015). 35 Hitt and Chambers, op. cit., suggest that an aquatic life benchmark for total dissolved selenium concentrations using the criteria that EPA relied upon to establish a benchmark for electrical conductivity would be between four and seven micrograms per liter, at least for fish. 36 U.S. Environmental Protection Agency, ‘‘Quality Criteria for Water’’ (1976), p. 200. 37 Id.

The proposed rule would address the environmental and human health concerns related to selenium by requiring collection of baseline hydrologic and geologic information on this element. If selenium is present in any of the overburden to be removed as part of the mining process, the proposed rule would require that the permit include limits on selenium discharges to prevent material damage to the hydrologic balance outside the permit area. The hydrologic reclamation plan and toxic materials handling plan must address selenium and the surface water and groundwater monitoring plans must include selenium. tkelley on DSK3SPTVN1PROD with PROPOSALS2 Impacts on Stream Flow Regime and Flooding In addition to the water quality impacts discussed above, mining may affect the flow regime of streams by removing springs and otherwise causing changes in base flow, water temperature, seasonal variations in flow, and fluctuations in flow in response to storm events. Reclaimed minesites generally exhibit both reduced evapotranspiration (as a result of forest loss due to mining) and reduced infiltration of rainfall (as a result of soil compaction during reclamation), compared to unmined areas. A 2009 study of flood response in Virginia watersheds found that flood magnitude increased with the amount of surfacemined land within the watershed. In contrast, logging operations that removed most forest cover in similar Virginia watersheds increased overall water yield within the watershed without increasing flood volume, a difference that the authors of the study attributed to the soil compaction associated with typical surface mine reclamation. Another study in Maryland found that the volume of surface runoff as a result of a storm in a watershed influenced by surface mining was significantly higher than the volume of runoff from an undisturbed forested watershed as a result of the same-size storm. The authors attributed this difference to soil compaction on the mined land, which reduced infiltration rates to less than 1 cm/hr, compared to 30 cm/hr in the undisturbed watershed. Increased surface runoff in response to storms increases the potential for flood damage and may adversely impact the hydrological function of the stream by causing stream channelization.38 Our proposed rule would address this issue 38 Sena at 27. VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 by minimizing soil compaction and maximizing reforestation. Impacts on Topography and Microclimates Mining impacts on the terrestrial environment include a loss of topographic complexity; i.e., regraded minesites generally are flatter and more uniform in terms of surface elevation and configuration when compared with the premining topography. U.S. Geological Survey studies of central Appalachia found that surface coal mining reduced ridgetop elevations by an average of 112 feet, raised valley floor elevations by an average of 174 feet, reduced slope steepness by 9.5–11 percent, and changed slope aspect 39 by 38–41 degrees.40 Changes are less dramatic in areas with flatter topography, but the same principle of greater uniformity and less topographic diversity after mining and regrading still applies. Regraded minesites usually lack the small drainageways and variations in slope and other topographical features found prior to mining. Therefore, they also lack the microclimates and associated ecosystems found prior to mining. Landsat data from 2007–2009 for the area containing a large mountaintop removal mining operation in West Virginia indicate that surface temperatures of areas disturbed by mining were warmer and more variable in all seasons except winter.41 Surface temperatures influence the type of vegetation that can survive on mined land and the extent and rate at which the premining plant community and associated fauna can recolonize the site. Impacts on Soils, Vegetation, and Terrestrial Wildlife Other terrestrial impacts include forest fragmentation (loss of large blocks of contiguous mature interior forest and increases in forest edge and grassland habitat), loss of native forests, changes in species composition and biodiversity of both plants and animals, and loss or severe compaction of soil horizons and organic matter. At least temporarily, mining of previously forested areas adversely impacts species that prefer or 39 Aspect is the compass direction that a slope faces. It has a significant effect on the soils and microclimate of the slope and hence on the plant and animal life found there, as well as the site’s productivity. 40 Wickham, James, Petra Bohall Wood, Matthew C.

Furthermore, conventional reclamation techniques typically result in heavily compacted soils that offer a hostile environment for native plant species and soil microorganisms, which means that minesites reclaimed by those techniques often are either planted with or colonized by nonnative species and remain in a state of arrested ecological succession. Both soil compaction and competitive herbaceous ground covers inhibit the establishment of native forests similar to those that occupied the area prior to mining. Soil compaction also reduces the site indices for tree growth, which means that the reclaimed minesite is not capable of supporting a forest with a productivity equal to that of the forest that either existed or could have existed prior to mining. Our proposed rule would address terrestrial impacts in a variety of ways, including a requirement for restoration of the premining drainage pattern to the extent possible and incorporation of elements of the Forestry Reclamation Approach. Use of that approach would minimize soil compaction and maximize reforestation and restoration of site productivity. Our proposed rule emphasizes revegetation with native species, restoration of natural plant communities whenever there is no conflict with implemented postmining land uses, and the protection or establishment of riparian corridors along streams to promote protection, restoration, and enhancement of fish, wildlife, and related environmental values. It also would modify the standards for approval of exceptions to the approximate original contour restoration requirement by limiting exceptions to those necessary to implement the postmining land use within the revegetation responsibility period. Draft Environmental Impact Statement (EIS) The draft EIS for this proposed rule contains an expanded discussion of the impacts of mining on the environment. Almost all the literature surveys and studies reviewed for this rulemaking process have been published since the adoption in 1983 of our principal regulations concerning protection of the hydrologic balance 42 and protection of fish, wildlife, and related environmental 42 48 E:\FR\FM\27JYP2.SGM FR 43956 (Sept. 26, 1983). 27JYP2 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules values,43 which underscores the need to update our regulations to reflect new scientific understanding of impacts associated with coal mining. Relationship to 2009 MOU This proposed rule helps fulfill our responsibilities under a memorandum of understanding (MOU) that the Secretary of the Department of the Interior, the Administrator of the EPA, and the Acting Assistant Secretary of the Army (Civil Works) entered into on June 11, 2009. This MOU implemented an interagency action plan designed to significantly reduce the harmful environmental consequences of surface coal mining operations in six Appalachian states and ensure that future mining is conducted consistent with federal law. Specifically, Part III.A. of the MOU provides that we will review our ‘‘existing regulatory authorities and procedures to determine whether regulatory modifications should be proposed to better protect the environment and public health from the impacts of Appalachian surface coal mining.’’ It also provides that, at a minimum, we will consider revisions to the stream buffer zone rule published December 12, 2008,44 and our existing regulatory requirements concerning approximate original contour. Ultimately, we determined that development of a comprehensive, nationally applicable stream protection rule would be the most appropriate and effective method of achieving the purposes and requirements of SMCRA, as well as meeting the goals set forth in the MOU.45 III. What needs does this proposed rule address? All versions of the stream buffer zone rule that we have adopted over the years, including the version now in effect, focused primarily on activities in or within 100 feet of the stream itself.46 43 48 FR 30312 (Jun. 30, 1983). U.S. District Court for the District of Columbia vacated the 2008 stream buffer zone rule on February 20, 2014, in National Parks Conservation Ass’n v. Jewell, 2014 U.S. Dist. LEXIS 152383 (D.D.C. Feb. 20, 2014). See also 79 FR 76227–76233 (Dec. 22, 2014). 45 In keeping with our commitment in the MOU, we considered making revisions to our approximate original contour regulations. Ultimately, we decided not to propose any major changes to our permitting requirements and performance standards concerning approximate original contour restoration at this time because of cost concerns and perceived difficulty of implementation. However, we are proposing revisions to our regulations governing exceptions to the requirement to restore the approximate original contour. 46 The 2008 rule was somewhat broader in that it also included provisions intended to minimize the creation of excess spoil and to limit the footprint of excess spoil fills. tkelley on DSK3SPTVN1PROD with PROPOSALS2 44 The VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 Yet, mining activities beyond the 100foot stream buffer zone can adversely impact the quality and quantity of water in streams by disturbing aquifers, by altering the physical and chemical nature of recharge zones as well as surface-water runoff and infiltration rates and drainage patterns, and by modifying the topography and vegetative composition of the watershed. Thus, there are many components of our regulations that could be revised to improve implementation of SMCRA with regard to protection of streams in particular and the hydrologic balance in general. We have identified six specific areas in which we propose to revise our regulations to better protect streams and associated environmental values. First, while ephemeral streams derive their flow from surface runoff from precipitation events, perennial and intermittent streams derive their flow from both groundwater discharges and surface runoff from precipitation events. Therefore, there is a need to clearly define the point at which adverse mining-related impacts on both groundwater and surface water reach an unacceptable level; that is, the point at which adverse impacts from mining cause material damage to the hydrologic balance outside the permit area. Neither SMCRA nor the existing regulations define the term ‘‘material damage to the hydrologic balance outside the permit area’’ or establish criteria for determining what level of adverse impacts would constitute material damage. In particular, there is no requirement that the SMCRA regulatory authority establish a specific standard for conductivity or selenium, both of which can have deleterious effects on aquatic life at elevated levels. Second, there is a need to collect adequate premining data about the site of the proposed mining operation and adjacent areas to establish a comprehensive baseline that will facilitate evaluation of the effects of mining. The existing rules require data only for a limited number of waterquality parameters rather than the full suite needed to establish a complete baseline against which the impacts of mining can be compared. The existing rules also contain no requirement for determining the biological condition of streams within the proposed permit and adjacent areas, so there is no assurance that the permit application will include baseline data on aquatic life. Third, there is a need for effective, comprehensive monitoring of groundwater and surface water during and after both mining and reclamation and during the revegetation PO 00000 Frm 00009 Fmt 4701 Sfmt 4702 44443 responsibility period to provide realtime information documenting miningrelated changes in the values of the parameters being monitored. Similarly, there is a need to require monitoring of the biological condition of streams during and after mining and reclamation to evaluate changes in aquatic life. Proper monitoring will enable timely detection of any adverse trends and timely implementation of any necessary corrective measures. The existing rules require monitoring of only water quantity and a limited number of waterquality parameters, not all parameters necessary to evaluate the impact of mining and reclamation. The existing rules do not ensure that the number and location of monitoring points will be adequate to determine the impact of mining and reclamation. They also allow discontinuance or reduction of water monitoring too early to ascertain the impacts of mining and reclamation on water quality with a reasonable degree of confidence, especially for groundwater. Fourth, there is a need to ensure protection or restoration of streams and related resources, including the headwater streams that are important to maintaining the ecological health and productivity of downstream waters. The existing rules have not always been applied in a manner sufficient to ensure protection or restoration of streams, especially with respect to the ecological function of streams. Maintenance, restoration, or establishment of riparian corridors or buffers, comprised of native species, for streams is a critical element of stream protection. In forested areas, riparian buffers for streams moderate the temperature of water in the stream, provide food (in the form of fallen leaves and other plant parts) for the aquatic food web, roots that stabilize stream banks, reduce surface runoff, and filter sediment and nutrients in surface runoff. Fifth, there is a need to ensure that permittees and regulatory authorities make use of advances in information, technology, science, and methodologies related to surface and groundwater hydrology, surface-runoff management, stream restoration, soils, and revegetation, all of which relate directly or indirectly to protection of water resources. Sixth, there is a need to ensure that land disturbed by surface coal mining operations is restored to a condition capable of supporting the uses that it was capable of supporting before any mining, including both those uses dependent upon stream protection or restoration and those uses that promote or support protection and restoration of E:\FR\FM\27JYP2.SGM 27JYP2 44444 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules tkelley on DSK3SPTVN1PROD with PROPOSALS2 streams and related environmental values. Existing rules and permitting practices have focused primarily on the land’s suitability for a single approved postmining land use and they have not always been applied in a manner that results in the construction of postmining soils that provide a growth medium suitable for restoration of premining site productivity. A corollary need is to ensure that reclaimed minesites are revegetated with native species unless and until a conflicting postmining land use, such as intensive agriculture, is implemented. Soil characteristics and the degree and type of revegetation have a major impact on surface-water runoff quantity and quality as well as on aquatic life and the terrestrial ecosystems dependent upon perennial and intermittent streams. Under the existing rules, sites with certain postmining land uses have been revegetated with non-native species even when the postmining land use is not implemented prior to final bond release and even on those portions of the site where non-native species are not necessary to achieve the postmining land use. The proposed rule would address these needs in the manner described in Part IX of this preamble. As mentioned in Part II of this preamble, we determined that improved protection of the hydrologic balance, especially streams, and related environmental values would benefit all regions of the country, not just Appalachia. In addition, one of the reasons SMCRA was enacted was to ensure a minimum level of environmental protection nationwide by establishing national surface coal mining and reclamation standards to prevent competition for coal markets from undermining the ability of states to maintain adequate regulatory programs for coal mining operations within their borders. See section 101(g) of SMCRA, 30 U.S.C. 1201(g). Thus, we concluded that a nationwide rule is required to clearly articulate a minimum standard for protection of the hydrologic balance, especially streams, and related environmental values that strikes an appropriate balance between environmental protection and the Nation’s need for coal. IV. What Clean Water Act programs protect streams? The goal of the Clean Water Act is to ‘‘restore and maintain the chemical, physical, and biological integrity of the Nation’s waters.’’ 47 To achieve that objective, section 301 of the Clean Water 47 33 U.S.C. 1251(a). VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 Act 48 prohibits the discharge of pollutants from point sources into waters of the United States unless consistent with the requirements of the Act. Section 402 of the Clean Water Act 49 governs the discharge of pollutants other than dredged or fill material, while section 404 50 governs the discharge of dredged or fill material into waters of the United States. Section 303 Water Quality Standards Section 303 of the Clean Water Act 51 requires states to adopt water quality standards applicable to their intrastate and interstate waters. Water quality standards assist in maintaining the physical, chemical, and biological integrity of a water body by designating uses, setting water quality criteria to protect those uses, and establishing provisions to protect water quality from degradation. Water quality standards established by states 52 are subject to EPA review. 40 CFR 131.5; 33 U.S.C. 1313(c). EPA may object to stateadopted water quality standards and may require changes to the stateadopted water quality standards and, if the state does not respond to EPA’s objections, EPA may promulgate federal standards. 33 U.S.C. 1313(c)(3)–(4); 40 CFR 131.5, 131.21. Water quality criteria may be expressed numerically and implemented in permits through specific numeric limitations on the concentration of a specific pollutant in the water (e.g., 0.1 milligrams of chromium per liter) or by more general narrative standards applicable to a wide set of pollutants. To assist states in adopting water quality standards that will meet with EPA’s approval, Congress authorized EPA to develop and publish recommended criteria for water quality that accurately reflect ‘‘the latest scientific knowledge.’’ 33 U.S.C. 1314(a). Water quality standards are not self-implementing; they are implemented through permits, such as the section 402 permit or the section 404 permit. 33 U.S.C. 1311(b)(1)(C); 40 CFR 122.44(d), 230.10(b). Section 401 Water Quality Certification State water quality standards are incorporated into all federal Clean Water Act permits through section 401, which requires each applicant to submit U.S.C. 1311. U.S.C. 1342. 50 33 U.S.C. 1344. 51 33 U.S.C. 1313. 52 EPA may treat an eligible federally-recognized Indian tribe in the same manner as a state for implementing and managing certain environmental programs, including under the Clean Water Act.

Thus, section 401 provides states with a veto over federal permits that may allow exceedances of state water quality standards. It also empowers states to impose and enforce water quality standards that are more stringent than those required by federal law. 33 U.S.C. 1370. Section 402 National Pollutant Discharge Elimination System (NPDES) Section 402 of the Clean Water Act governs discharges of pollutants other than dredged or fill material into waters of the United States. Permits issued under the authority of section 402 are known as NPDES permits. They typically contain numerical limits called effluent limitations that restrict the amounts of specified pollutants that may be discharged. NPDES permits must contain technology-based effluent limits and any more stringent water quality-based effluent limits necessary to meet applicable state water quality standards. 33 U.S.C. 1311(b)(1)(A) and (C), 33 U.S.C. 1342(a); 40 CFR 122.44(a)(1) and (d)(1). Water qualitybased effluent limitations are required for all pollutants that the permitting authority determines ‘‘are or may be discharged at a level [that] will cause, have the reasonable potential to cause, or contribute an excursion above any [applicable] water quality standard, including State narrative criteria for water quality.’’ 40 CFR 122.44(d)(1)(i). The procedure for determining the need for water quality-based effluent limits is called a reasonable potential analysis, or ‘‘RPA.’’ Section 402 permits are issued by EPA unless the state has an approved program whereby the state issues the permits, subject to EPA oversight. 33 U.S.C. 1342(b)(e); 551 U.S. 644, 650–651 (2007). The state must submit draft permits to EPA for review, and EPA may object to a proposed permit that is not consistent with the Clean Water Act and federal regulations. 33 U.S.C. 1342(d); 40 CFR 123.43 and 123.44. If the state does not adequately address EPA’s objections, EPA may assume the authority to issue the permit. 33 U.S.C. 1342(d)(4). EPA’s procedures for the review of state-issued permits are set forth in regulations at 40 CFR 123.44 and in memoranda of agreement with the states. Section 404 Permits Section 404(a) of the Clean Water Act authorizes the Secretary of the Army, acting through the U.S. Army Corps of Engineers (ACE or the Corps), to ‘‘issue E:\FR\FM\27JYP2.SGM 27JYP2 tkelley on DSK3SPTVN1PROD with PROPOSALS2 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules permits . . . for the discharge of dredged or fill material into the navigable waters at specified disposal sites.’’ 33 U.S.C. 1344(a). By this authority, the ACE regulates discharges of dredged and fill material into waters of the United States in connection with surface coal mining and reclamation operations. The ACE’s regulations governing section 404 permit procedures are set forth at 33 CFR part 325. Although the ACE is the permitting authority under section 404, EPA has an important role in the permitting process. Section 404(b) of the Clean Water Act requires that permitting decisions comply with guidelines developed by EPA in conjunction with the ACE. These guidelines, which are referred to as the ‘‘404(b)(1) Guidelines,’’ are codified in 40 CFR part 230. Among other things, the 404(b)(1) Guidelines prohibit the discharge of fill if it would cause or contribute to a violation of a water quality standard or cause or contribute to significant degradation of the waters of the United States. 40 CFR 230.10(b), (c)(1) through (c)(3). The 404(b)(1) Guidelines require the ACE to analyze more than 15 different factors that could be impacted by the proposed action, including substrate, suspended particulates, turbidity, water quality, water circulation, water level fluctuations, salinity gradients, threatened and endangered species, aquatic organisms in the food web, other wildlife special aquatic sites, water supplies, fisheries, recreation, aesthetics, and parks. 40 CFR 230(c) through (f). The 404(b)(1) Guidelines provide that the ACE must ensure that the proposed discharges would not cause or contribute to significant adverse effects on human health or welfare, aquatic life, or aquatic ecosystems. 40 CFR 230.10(c)(1) through (c)(3). Before the ACE may issue a section 404 permit, it must provide notice to the public, EPA, and other resource agencies, which may provide comments to the ACE for consideration. 33 CFR 325.3(d). In addition, the ACE and EPA have entered into a Memorandum of Agreement (MOA) as directed by section 404(q) of the Clean Water Act, 33 U.S.C. 1344(q), that expressly recognizes that ‘‘the EPA has an important role in the Department of the Army Regulatory Program under the Clean Water Act[.]’’ The MOA provides that ‘‘[p]ursuant to its authority under section 404(b)(1) of the Clean Water Act, the EPA may provide comments to the Corps identifying its views regarding compliance with the section 404(b)(1) Guidelines’’ and ‘‘[t]he Corps will fully VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 consider EPA’s comments when determining [compliance] with the National Environmental Policy Act, and other relevant statutes, regulations, and policies.’’ Id. In addition, section 404(c) of the Clean Water Act provides EPA with the authority to prohibit, withdraw, deny, or restrict the specification of disposal sites that would otherwise be authorized by a section 404 permit. This provision is often referred to as EPA’s permit veto authority. The ACE reviews individual permit applications under section 404(a) of the Clean Water Act on a case-by-case basis. 33 U.S.C. 1344(a). Individual permits may be issued or denied after a review involving, among other things, sitespecific documentation and analysis, opportunity for public hearing, public interest review, and a formal determination that the permit is lawful and warranted. 33 CFR parts 320, 323, and 325. Not every discharge is of such significance that an individual evaluation of the discharge’s environmental effects is necessary. Instead, section 404(e) of the Clean Water Act authorizes the Secretary of the Army to issue general permits for categories of activities involving discharges of dredged or fill material that, as a group, have only minimal impacts on the waters of the United States. The ACE can issue these general permits (as well as individual permits) on a state, regional, or nationwide basis. The ACE refers to general permits issued on a nationwide basis as ‘‘nationwide permits’’ (NWP). NWPs must be reviewed reissued every 5 years to remain valid. The ACE last reissued the NWPs on February 21, 2012 (77 FR 10184). NWP 21, Surface Coal Mining Activities, provides authorization for the discharge of dredged or fill material into waters of the United States when those discharges are associated with surface coal mining activities. The permittee must submit a preconstruction notification to the ACE district engineer and receive written authorization prior to commencing the activity. The ACE review of preconstruction notifications under NWP 21 is focused on the individual and cumulative adverse effects to the aquatic environment and on determining appropriate mitigation should mitigation be necessary. The ACE review does not extend to upland areas or the mining operation as a whole. To qualify for NWP 21, an activity must meet all of the following criteria: PO 00000 Frm 00011 Fmt 4701 Sfmt 4702 44445 (1) The activities are already authorized or are currently being processed by a SMCRA-approved state program or an integrated permit processing procedure by the Department of the Interior. (2) The discharge will not cause the loss of more than 1⁄2 acre of non-tidal waters of the United States, including the loss of no more than 300 linear feet of streambed, unless, for intermittent and ephemeral streambeds, the ACE district engineer waives the 300-linearfoot limit by making a written determination concluding that the discharge will result in minimal individual and cumulative adverse effects. (3) The discharge is not associated with the construction of valley fills which are fill structures associated with surface coal mining activities that are typically constructed within valleys associated with steep, mountainous terrain. Any surface mining activity that does not meet all three criteria must apply for an individual permit instead unless the activity qualifies for NWP 49 as discussed below. Two other NWPs may apply to coal mining activities under SMCRA. NWP 49, Coal Remining Activities, applies to discharges of dredged or fill material into non-tidal waters of the United States when those discharges are associated with the remining and reclamation of lands that were previously mined for coal. The activities must already be authorized by the SMCRA regulatory authority or be in process as part of an integrated permit processing procedure under SMCRA. The permittee may conduct new coal mining activities in conjunction with the remining activities when he or she clearly demonstrates to the ACE that the overall mining plan will result in a net increase in aquatic resource functions. The ACE will consider the SMCRA regulatory authority’s decision regarding the amount of currently undisturbed adjacent lands needed to facilitate the remining and reclamation of the previously mined area. The total area disturbed by new mining must not exceed 40 percent of the total acreage covered by both the remined area and the additional area necessary to carry out the reclamation of the previously mined area. The permittee must submit a pre-construction notification and a document describing how the overall mining plan will result in a net increase in aquatic resource functions to the district engineer and receive written authorization prior to commencing the activity.

This NWP does not authorize coal preparation and processing activities outside the minesite or discharges into nontidal wetlands adjacent to tidal waters. The permittee must submit a pre-construction notification to the ACE district engineer and receive written authorization prior to commencing the activity. V. What provisions of SMCRA provide legal authority for the proposed rule? This proposed rule would more completely implement SMCRA’s permitting requirements and performance standards and better achieve the purposes of SMCRA as set forth in section 102 of the Act.53 It is intended to balance all relevant purposes of the Act, which include ensuring that surface coal mining operations are conducted in a manner that protects the environment, establishing a nationwide program to protect society and the environment from the adverse effects of surface coal mining operations, and ensuring a coal supply adequate for our Nation’s energy needs. Our proposed rule is intended to address the adverse impacts and needs discussed in Parts II and III of this preamble by adding specificity to and otherwise revising our existing regulations to more completely implement various provisions of SMCRA, including, but not limited to: Section 101(c),54 in which Congress finds that ‘‘many surface coal mining operations result in disturbances of surface areas that burden and adversely affect commerce and the public welfare by * * * polluting the water, by destroying fish and wildlife habitats, by impairing natural beauty, * * * and by 53 30 54 30 counteracting governmental programs and efforts to conserve soil, water, and other natural resources.’’ Section 102(a),55 which provides that one of the purposes of the Act is to ‘‘establish a nationwide program to protect society and the environment from the adverse effects of surface coal mining operations.’’ Section 102(d),56 which provides that one of the purposes of the Act is to ‘‘assure that surface coal mining operations are so conducted as to protect the environment.’’ Section 102(f),57 which provides that one of the purposes of the Act is to ‘‘strike a balance between protection of the environment and agricultural productivity and the Nation’s need for coal as an essential source of energy.’’ Section 102(m),58 which provides that the Secretary, wherever necessary, ‘‘exercise the full reach of Federal constitutional powers to insure the protection of the public interest through effective control of surface coal mining operations.’’ Section 201(c)(2),59 which provides that the Secretary, acting through OSMRE, will ‘‘publish and promulgate such rules and regulations as may be necessary to carry out the purposes and provisions of this Act.’’ Section 510(b)(2),60 which provides that the regulatory authority may not approve a permit application unless it first finds that ‘‘the applicant has demonstrated that reclamation as required by this Act and the State or Federal program can be accomplished under the reclamation plan contained in the permit application.’’ Section 510(b)(3),61 which provides that the regulatory authority may not approve a permit application unless it first finds that the proposed operation ‘‘has been designed to prevent material damage to the hydrologic balance outside the permit area.’’ Section 515(b)(2),62 which requires that the permittee restore land affected by surface coal mining and reclamation operations ‘‘to a condition capable of supporting the uses which it was capable of supporting prior to mining.’’ This paragraph also allows restoration to a condition capable of supporting ‘‘higher or better uses of which there is reasonable likelihood,’’ provided certain conditions relating to public health or U.S.C. 1202.

Section 515(b)(19),65 which requires that surface coal mining and reclamation operations ‘‘establish on the regraded areas, and all other lands affected, a diverse, effective, and permanent vegetative cover of the same seasonal variety native to the area of land to be affected and capable of selfregeneration and plant succession at least equal in extent of cover to the natural vegetation of the area; except that introduced species may be used in the revegetation process where desirable and necessary to achieve the approved postmining land use plan.’’ Section 516(b)(6) 66 contains generally similar provisions applicable to underground mining operations.

While this provision does not provide rulemaking authority, it does place limits on rulemaking under SMCRA. tkelley on DSK3SPTVN1PROD with PROPOSALS2 VI. What is the history of our regulation of coal mining in relation to buffer zones for streams? The U.S. House of Representatives first passed a bill (H.R. 6482) to regulate surface coal mining operations in 1972. Section 9(a) of that bill included a flat prohibition on mining within 100 feet of any ‘‘body of water, stream, pond, or lake to which the public enjoys use and access, or other private property.’’ However, the bill never became law and the provision did not appear in either the House or Senate versions of the bills that ultimately became SMCRA. Therefore, nothing in SMCRA specifically establishes or requires a buffer zone for streams, although sections 515(b)(24) and 516(b)(11) of SMCRA 72 require that mining operations minimize disturbances and adverse impacts on fish, wildlife, and related environmental values to the extent possible using the best technology currently available. We have consistently interpreted those and other provisions of SMCRA as meaning that protection of perennial and intermittent streams, with their intrinsic value to fish and wildlife, is an important element of the environmental protection regime that SMCRA established. Since the enactment of SMCRA, we have adopted four sets of regulations, which we discuss below, that included the concept of a buffer zone for streams. The 1977 Stream Buffer Zone Rule In 1977, we published initial regulatory program regulations providing that no land within 100 feet of an intermittent or perennial stream could be disturbed by surface coal mining and reclamation operations unless the regulatory authority specifically authorizes those operations. See 30 CFR 715.17(d)(3) and 717.17(d), as published at 42 FR 62639, 62686, 62697 (Dec. 13, 1977). We stated that we adopted that rule as a means ‘‘to protect stream channels from abnormal erosion’’ from nearby upslope mining activities.73 However, that rule, which applies only to the now-limited subset of surface coal mining and reclamation operations subject to the initial regulatory program, does not specify the conditions under which the regulatory authority may authorize surface coal mining operations within the buffer zone. The 1979 Stream Buffer Zone Rule In 1979, we published the original version of our permanent regulatory program regulations. Those regulations, as codified at 30 CFR 816.57 and 817.57, provided that, with the exception of stream diversions, the surface of land within 100 feet of a perennial stream or a non-perennial stream with a biological community could not be disturbed by surface mining activities or surface operations and facilities associated with an underground mine unless the regulatory authority specifically authorized mining-related activities closer to or through the stream. Under the regulations, the regulatory authority could grant that authorization only after making a finding that the original stream channel would be restored and that, during and after the mining, the water quantity and quality in the section of the stream within 100 feet of the mining activities would not be adversely affected. Paragraph (c) of these rules provided that a biological community existed if, at any time, the stream contained an assemblage of two or more species of arthropods or molluscan animals that were adapted to flowing water for all or part of their life cycle, dependent upon a flowing water habitat, reproducing or could reasonably be expected to reproduce in the water body where they are found, and longer than two millimeters at some stage of the part of their life cycle spent in the flowing water habitat. See 44 FR 14902, 15175 (Mar. 13, 1979). The preamble to the 1979 rules explains that the purpose of the revised rules was to implement paragraphs (b)(10) and (b)(24) of section 515 of the Act.74 It states that ‘‘[b]uffer zones are required to protect streams from the adverse effects of sedimentation and from gross disturbance of stream channels,’’ but that ‘‘if operations can be conducted within 100 feet of a stream in an environmentally acceptable manner, they may be approved.’’ 75 In addition, it states that ‘‘[t]he 100-foot limit is based on typical distances that should be maintained to protect stream 73 Id. 71 30 U.S.C. 1292(a). 72 30 U.S.C. 1265(b)(24) and 1266(b)(11).

PO 00000 Frm 00013 channels from sedimentation,’’ but that, while the 100-foot standard provides a simple rule for enforcement purposes, ‘‘site-specific variation should be made available when the regulatory authority has an objective basis for either increasing or decreasing the width of the buffer zone.’’ 76 The 1983 Stream Buffer Zone Rule In 1983, we revised 30 CFR 816.57 and 817.57 by deleting the requirement to restore the original stream channel. We also replaced the biological community criterion for determining which non-perennial streams are protected under the rule with a requirement for protection of all perennial and intermittent streams. We redefined an intermittent stream as a stream or reach of a stream that (a) drains a watershed of at least one square mile or (b) is below the local water table for at least some part of the year and obtains its flow from both surface runoff and groundwater discharge. Finally, we replaced the 1979 finding with a requirement that the regulatory authority find that the proposed mining activities would not cause or contribute to a violation of applicable state or federal water quality standards and would not adversely affect the quantity or quality of the water in the stream or the other environmental resources of the stream. See 48 FR 30312, 30327–30328 (Jun. 30, 1983). In 1983, we also adopted revised performance standards for coal preparation plants not located within the permit area of a mine. At that time, we decided not to apply the stream buffer zone rule to those preparation plants. See 30 CFR 827.12 and the preamble to those rules at 48 FR 20399 (May 5, 1983). The preamble to the 1983 stream buffer zone rules reiterates the general rationale for adoption of a stream buffer zone rule that we specified in the preamble to the 1979 rules. In addition, it identifies the reason for replacing the biological community criterion with the intermittent stream threshold as a matter of improving the ease of administration and eliminating the possibility of applying the rule to ephemeral streams: The biological-community standard was confusing to apply since there are areas with ephemeral surface waters of little biological or hydrologic significance which, at some time of the year, contain a biological community as defined by previous § 816.57(c). Thus, much confusion arose when operators attempted to apply the previous rule’s standards to springs, seeps, 76 Id.

While some small biological communities which contribute to the overall production of downstream ecosystems will be excluded from special buffer-zone protection under final § 816.57(a), the purposes of Section 515(b)(24) of the Act will best be achieved by providing a buffer zone for those streams with more significant environmentalresource values.77 Referring to those streams that would not be protected by 30 CFR 816.57, i.e., ephemeral streams, the preamble further states that ‘‘[i]t is impossible to conduct surface mining without disturbing a number of minor natural streams, including some which contain biota.’’ 78 Referring to those streams that would be protected by 30 CFR 816.57, i.e., perennial and intermittent streams, the preamble also states that ‘‘surface coal mining operations will be permissible as long as environmental protection will be afforded to those streams with more significant environmental-resource value.’’ 79 The preamble further provides that the revised rules ‘‘also recognize that intermittent and perennial streams generally have environmental-resource values worthy of protection under Section 515(b)(24) of the Act.’’ 80 In addition, the preamble notes that ‘‘[a]lthough final § 816.57 is intended to protect significant biological values in streams, the primary objective of the rule is to provide protection for the hydrologic balance and related environmental values of perennial and intermittent streams’’.81 It further states that ‘‘[t]he 100-foot limit is used to protect streams from sedimentation and help preserve riparian vegetation and aquatic habitats.’’ 82 We also stated that we removed the requirement to restore the original stream channel in deference to the stream-channel diversion requirements of 30 CFR 816.43 and 817.43 and to clarify that there does not have to be a stream diversion for mining to occur inside the buffer zone.83 Finally, the preamble states that we expanded the finding in 30 CFR 816.57(a)(1) to include environmental resources of the stream other than water quantity and quality to clarify ‘‘that tkelley on DSK3SPTVN1PROD with PROPOSALS2 77 48 FR 30313 (Jun. 30 1983).

The National Wildlife Federation challenged this regulation as being inconsistent with sections 515(b)(10) and (24) of the Act, primarily because it deleted the biological community criterion for non-perennial stream protection. However, the court rejected that challenge, finding without elaboration that the ‘‘regulation is not in conflict with either section 515(b)(10) or 515(b)(24).’’ 85 The court also noted that the Secretary had properly justified the rule change on the grounds that the previous rule was confusing and difficult to apply without protecting areas of little biological significance. Industry also challenged the 1983 version of 30 CFR 817.57(a) to the extent that it included all underground mining activities. However, industry withdrew its challenge when the Secretary stipulated that the rule would apply only to surface lands and surface activities associated with underground mining.86 Historically, we and some state regulatory authorities applied the 1983 stream buffer zone rule in a manner that allowed the placement of excess spoil fills, refuse piles, slurry impoundments, and sedimentation ponds in intermittent and perennial streams within the permit area. However, as discussed at length in the preamble to a 2004 proposed rule,87 which we never finalized, there has been considerable controversy over the proper interpretation of both the Clean Water Act and our 1983 rules as they apply to the placement of fill material in or near perennial and intermittent streams. One interpretation of the 1983 stream buffer zone rules appears in our annual oversight reports for West Virginia for 1999 and 2000, which state that the stream buffer zone rule does not apply to the footprint of a fill placed in a perennial or intermittent stream as part of a surface coal mining operation.

However, on August 9, 1999, OSMRE, the U.S. Army Corps of Engineers, EPA, and the West Virginia Division of Environmental Protection (WVDEP) signed a memorandum of understanding (MOU) in which all four agencies in effect agreed to an interpretation that allowed valley fills in intermittent or perennial streams to be approved only if the buffer zone findings were made for the filled stream segments. The MOU also stated that the Clean Water Act Section 404(b)(1) Guidelines at 40 CFR part 230 contain requirements comparable to the findings required by the combination of OSMRE’s 1983 stream buffer zone rule and the West Virginia stream buffer zone rule. Consequently, the MOU found that, ‘‘where a proposed fill is consistent with the requirements of the Section 404(b)(1) Guidelines and applicable requirements for Section 401 certification of compliance with water quality standards, the fill would also satisfy the criteria for granting a stream buffer zone variance under SMCRA and WVDEP regulations.’’ 88 As a result of the signing of the MOU, the court approved an unopposed motion to dismiss the case mentioned above 89 as moot in an order filed September 23, 1999. In a lawsuit filed in the U.S. District Court for the Southern District of West Virginia in July 1998, plaintiffs asserted that the 1983 stream buffer zone rule should be interpreted to allow mining activities through a perennial or intermittent stream or within the buffer zone for a perennial or intermittent stream only if the activities are minor incursions.90 They argued that the rule did not allow substantial segments of a perennial or intermittent stream to be buried underneath excess spoil fills or other mining-related structures.91 On October 20, 1999, the district court ruled in favor of the plaintiffs on this 88 Memorandum Of Understanding among the U.S. Office of Surface Mining, U.S. Environmental Protection Agency, U.S. Army Corps of Engineers, and West Virginia Division Of Environmental Protection for the Purpose of Clarifying the Application of Regulations Related to Stream Buffer Zones under the Surface Mining Control and Reclamation Act for Surface Coal Mining Operations that Result in Valley Fills, August 9, 1999, p. 4. 89 West Virginia Highlands Conservancy v.

See Bragg v. West Virginia Coal Ass’n, 248 F.3d 275, 296 (4th Cir. 2001), cert. denied, 534 U.S. 1113 (2002). While the Fourth Circuit did not interpret the 1983 version of the stream buffer zone rule, the brief for the federal appellants in that case included another interpretation of the regulation in their brief. In sum, the federal appellants supported an interpretation based on the district court decision and stated that 30 CFR 816.57 ‘‘prohibits the burial of substantial portions of intermittent and perennial streams beneath excess mining spoil.’’ 95 In a different case related to the issuance of a nationwide section 404 permit under the Clean Water Act, the U.S. District Court for the Southern District of West Virginia stated in an opinion that SMCRA and the 1983 stream buffer zone rule do not authorize tkelley on DSK3SPTVN1PROD with PROPOSALS2 92 Id. 93 Id. at 650–653, 661.

The traditional interpretation of the [stream buffer zone] is in harmony with this Court’s decision in Rivenburgh.’’ 99 Additionally, the U.S. Court of Appeals for the Fourth Circuit has discussed SMCRA’s role in the regulation of valley fills in the context of a challenge to individual permits under section 404 of the Clean Water Act.100 See Ohio Valley Envtl.

The 2008 Rule In 2004, we proposed a rule to revise the 1983 version of the stream buffer zone rule in order ‘‘to clarify the circumstances in which mining activities such as the construction of excess spoil fills may be allowed within the [stream buffer zone]’’.101 Although we abandoned this proposed rule, we proposed another rule in 2007, in part ‘‘to end the ambiguity in interpretation of the stream buffer zone rules and to ensure that regulatory authorities, mine operators, other governmental entities, 96 Kentuckians for the Commonwealth, Inc. v.

Among other things, the rule required that mining operations be designed to minimize the creation of excess spoil and that permit applicants consider a range of reasonable alternatives to the disposal of excess spoil and coal mine waste in perennial or intermittent streams or their buffer zones and select the alternative with the least overall adverse impact on fish, wildlife, and related environmental values. With respect to activities in the stream itself, it replaced the findings in the 1983 rule with a requirement for a finding that avoiding disturbance of the stream is not reasonably possible. It also required a demonstration of compliance with the Clean Water Act before the permittee initiates mining activities in a perennial or intermittent stream if those activities require authorization or certification under the Clean Water Act. With respect to activities confined to the stream buffer zone, the rule replaced the findings in the 1983 rule with a requirement for a finding that avoiding disturbance of land within 100 feet of the stream either is not reasonably possible or is not necessary to meet the fish and wildlife and hydrologic balance protection requirements of the regulatory program. That rule, which we refer to in this preamble as the 2008 rule, took effect January 12, 2009. For a more detailed history of the 2008 rule, please refer to the discussion in the preamble to that rule.103 Litigation Concerning the 2008 Rule Shortly after publication of the 2008 rule, ten environmental organizations challenged the validity of the rule. See Coal River Mountain Watch v. Salazar (‘‘Coal River’’), No. 08–2212 (D.D.C., filed Dec. 22, 2008) and National Parks Conservation Ass’n v. Salazar (‘‘NPCA’’), No. 09–115 (D.D.C., filed Jan. 16, 2009). In NPCA, the Federal Government filed a motion on April 27, 2009, for voluntary remand and vacatur of the 2008 rule. The motion was based on the Secretary’s determination that OSMRE 102 72 FR 48890, 48892 (Aug. 24, 2007). 73 FR 75814, 75816–75818 (Dec. 12, 103 See 2008).

In Coal River, the Federal Government filed a motion on April 28, 2009, to dismiss the complaint as moot if the court granted the motion in NPCA. On August 12, 2009, the court denied the Federal Government’s motion in NPCA, holding that, absent a ruling on the merits, significant new evidence, or consent of all the parties, a grant of vacatur would allow the government to improperly bypass the procedures set forth in the Administrative Procedure Act, 5 U.S.C. 551 et seq., for repealing an agency rule. On the same date, the court denied the Federal Government’s motion to dismiss in Coal River. See Nat’l Parks Conservation Ass’n v. Salazar, 660 F. Supp. 2d 3, 4 (D.D.C. 2009). On March 19, 2010, the parties involved in the NPCA and Coal River litigation signed a settlement agreement in which the Secretary agreed to make best efforts to sign a proposed rule to amend or replace the 2008 rule within a year and sign a final rule within approximately 18 months. On April 2, 2010, the court granted the parties’ motion to hold in abeyance further judicial proceedings concerning the 2008 rule to allow time for us to conduct this rulemaking. However, for a variety of reasons, the Secretary had not yet published a proposed rule as of the beginning of 2013. Given this delay, on March 19, 2013, the court granted the plaintiffs’ motions to resume the litigation. On February 20, 2014, the court vacated the 2008 rule because ‘‘OSM’s determination that the revisions to the stream protection rule encompassed by the 2008 Rule would have no effect on threatened and endangered species or critical habitat was not a rational conclusion’’ and that therefore our failure to initiate consultation on the 2008 rule was a violation of section 7(a)(2) of the Endangered Species Act.

The court in NPCA remanded the vacated rule to us for further proceedings consistent with the decision.105 The court’s decision also stated that vacatur of the 2008 rule resulted in reinstatement of the rule in effect before the vacated rule took effect.106 In response, OSMRE published a notice of vacatur in the Federal Register.107 Therefore, the proposed rule that we are publishing today uses the pre-2008 rules as the baseline for all proposed changes. The 2009 Memorandum of Understanding As mentioned above, on June 11, 2009, the Secretary, the Administrator of the EPA, and the Acting Assistant Secretary of the Army (Civil Works) entered into an MOU 108 implementing an interagency action plan designed to significantly reduce the harmful environmental consequences of surface coal mining operations in six Appalachian states,109 while ensuring that future mining remains consistent with federal law. Among other things, in the MOU we committed to review our ‘‘existing regulatory authorities and procedures to determine whether regulatory modifications should be proposed to better protect the environment and public health from the impacts of Appalachian surface coal mining.’’ It also provides that, at a minimum, we will consider revisions to the 2008 rule and our regulatory requirements concerning approximate original contour.110 The proposed rule that we are publishing today is, in part, the result of our review of existing regulatory authorities and procedures as promised in the MOU. The proposed rule would replace the vacated 2008 rule and the reinstated pre-2008 rules. However, we have decided not to propose any major changes to our permitting requirements and performance standards concerning approximate original contour restoration 105 NPCA v. Jewell, U.S. Dist.

However, the court in NPCA did not grant the specific motion mentioned in the MOU. See Nat’l Parks Conservation Ass’n v. Salazar, 660 F. Supp. 2d 3, 4 (D.D.C. 2009). PO 00000 106 Id. 107 See Frm 00016 Fmt 4701 Sfmt 4702 at this time because of cost concerns and perceived difficulty of implementation.111 The Advance Notice of Proposed Rulemaking (ANPRM) On November 30, 2009 (74 FR 62664– 64668), we published an advance notice of proposed rulemaking, consistent with the MOU and National Parks Conservation Association v. Salazar, 660 F. Supp. 2d 3, 4 (D.D.C. 2009). Specifically, the notice described ten alternatives for revising the 2008 rule and related rules and invited the public to comment on those alternatives and to suggest other ways that the 2008 rule should be revised to better protect streams and implement the MOU. We also invited the public to identify provisions of our regulations other than the 2008 rule that should be revised to better protect the environment and the public from the impacts of Appalachian surface coal mining. We received approximately 32,750 comments during the 30-day comment period. After evaluating the comments that we received on the ANPRM, reexamining the 2008 rule, and reexamining practices in and outside Appalachia, we determined that development of a comprehensive stream protection rule would be the most appropriate and effective method of better achieving the purposes and requirements of SMCRA as well as the goals set forth in the MOU and the ANPRM. Consequently, we are proposing a rule that would identify measures that mine operators and SMCRA regulatory authorities must take to prevent or minimize mining-related impacts on streams and fish, wildlife and related environmental values. Thus, the scope of this proposed rule is broader than the scope of the 2008 rule, which focused primarily on excess spoil handling, coal mine waste disposal, and activities conducted in or near streams. Consistent with the broader scope of the proposed rule, we are preparing a new EIS, rather than supplementing the EIS prepared for the 2008 rule. We also are consulting with the U.S. Fish and Wildlife Service as required by section 7 of the Endangered Species Act. Furthermore, if we determine that adoption of this proposed rule may affect species under the jurisdiction of the National Marine Fisheries Service (NMFS), we will consult with NMFS, which is 111 The draft EIS and draft regulatory impact analysis for this rulemaking evaluate potential changes to approximate original contour requirements, including the addition of landforming and digital modeling requirements, as part of Alternative 4.

Comments that we received in response to the ANPRM differed as to whether the proposed rule should be national in scope or whether it should be limited to central Appalachia or to steep-slope mining operations. After evaluating those comments, we have decided to propose rules that are national in scope because streams are ecologically important regardless of topography or where they are located in the country. Measures to protect the quality and quantity of streamflow, both from surface sources and groundwater discharges, are likewise important regardless of topography or location. In addition, section 101(g) of SMCRA states that ‘‘[national] surface mining and reclamation standards are essential in order to insure that competition in interstate commerce among sellers of coal produced in different States will not be used to undermine the ability of the several States to improve and maintain adequate standards on coal mining operations within their borders.’’ In other words, national standards are necessary because they define a set of environmental protection requirements that a state cannot relax as an incentive to coal producers to either continue to mine coal in the state or to relocate to the state. Protecting our water resources and preventing water pollution is important everywhere, especially in the arid and semiarid West and portions of the country that are experiencing droughts. There is a need for consistent, scientifically-valid documentation of the premining physical, chemical, and biological condition of streams and the impacts of mining and reclamation on those streams. All permits should include plans for stream protection or restoration that require use of best practices to either maintain the ecological condition of streams or restore both the physical form and the ecological function of affected streams. The proposed rule is sufficiently flexible to accommodate the different regions where coal is mined and the differences in streams found in those regions. In addition, the proposed rule would address some concerns that commenters on the ANPRM expressed with respect to other provisions of our regulations that are not necessarily directly related to stream protection, but that are important in terms of protecting the hydrologic balance or better achieving other requirements and purposes of SMCRA. We also propose to reorganize, VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 revise, and streamline our rules to improve their readability and internal consistency, to update or remove obsolete provisions, to remove redundant and unneeded provisions, to be consistent with court decisions, and to incorporate plain language principles. VII. Why does the proposed rule include protective measures for ephemeral streams? Unlike the regulations implementing the Clean Water Act, the existing regulations implementing SMCRA contain no specific protections for ephemeral streams. As summarized in Part II of this preamble, scientific studies completed since the enactment of SMCRA and the adoption of our existing rules have documented the importance of headwater streams, including ephemeral streams, in maintaining the ecological health and function of streams downgradient of headwater streams. EPA recently completed a literature review of the importance of headwater streams and published a report summarizing the findings of more than 1,200 peerreviewed studies.112 With some exceptions, the report generally does not differentiate between the various types of headwaters streams, which consist of a mix of perennial, intermittent, and ephemeral streams, but it does emphasize that ephemeral streams are an important component of headwaters streams and that they have an effect on the form and function of downstream channels and aquatic life. Consistent with the findings of this report and other studies, our proposed rule includes some protections for ephemeral streams, tailored to their hydrologic and ecological functions. We also are considering adopting an alternative that would provide equal protection to all streams, without regard to whether the stream is perennial, intermittent, or ephemeral. We invite comment on whether we should adopt this alternative in the final rule and, if so, whether we should extend all the protections that this proposed rule would afford to perennial and intermittent streams to ephemeral streams or whether we should instead scale back those protections to avoid undue adverse impacts on the mining industry, while still providing improved 112 U.S. Environmental Protection Agency, Connectivity of Streams and Wetlands to Downstream Waters: A Review and Synthesis of the Scientific Evidence (Final Report).

The report states that the evidence unequivocally demonstrates that the stream channels, riparian wetlands, floodplain wetlands, and open waters that together form river networks are clearly connected to downstream waters in ways that profoundly influence downstream water integrity. According to the authors, the body of literature documenting connectivity and downstream effects is most abundant for perennial and intermittent streams and for riparian and floodplain wetlands. However, the report states that, although less abundant, the evidence for connectivity and downstream effects of ephemeral streams is strong and compelling, particularly in context with the large body of evidence supporting the physical connectivity and cumulative effects of channelized flows that form and maintain stream networks.113 The report identifies five principal contributions of ephemeral streams: (1) Providing streamflow to larger streams; (2) conveying water into local storage compartments such as ponds, shallow aquifers, or streambanks that are important sources of water for maintenance of the baseflow in larger streams; (3) transporting sediment, woody debris, and nutrients; (4) providing the biological connectivity that is necessary either to support the life cycle of some invertebrates or to facilitate the transport of terrestrial invertebrates that serve as food resources in downstream communities; and (5) influencing fundamental biogeochemical processes such as the assimilation and transformation of nitrogen that may otherwise have detrimental impacts on downstream communities. The report’s explanation of these contributions is summarized below. In addition, headwater streams, including ephemeral and intermittent streams, shape downstream channels by accumulating and gradually or episodically releasing stored materials such as sediment and large woody debris.114 These materials help structure stream and river channels by slowing the flow of water through channels and providing substrate and habitat for aquatic organisms.115 113 Id. 114 Id. at ES–7. at ES–8. 115 Id. E:\FR\FM\27JYP2.SGM 27JYP2 44452 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules Providing Streamflow to Larger Streams Ephemeral streams are hydrologically connected to downstream waters via channels that convey surface and subsurface water in direct response to precipitation. Moreover, these streams are the defining characteristic of many watersheds in arid and semi-arid regions of the United States; thus serving a critical role in the maintenance of water resources.116 Conveyance of Water Into Local Storage Compartments Ephemeral streams may convey water to local storage compartments, such as ponds, shallow aquifers, and streambanks, and recharge regional alluvial aquifers, depending upon the frequency, duration, magnitude, and timing of precipitation events. These local storage compartments are important sources of water for maintaining baseflow in perennial streams. Streamflow typically depends on the delayed (i.e., lagged) release of shallow groundwater from local storage, especially during dry periods and in areas with shallow groundwater tables and pervious subsurfaces. Relative to their cumulative surface area, an inordinate amount of groundwater recharge occurs in headwater ephemeral and intermittent channels within arid drainage basins. Furthermore, in the southwestern United States, short-term shallow groundwater storage in alluvial floodplain aquifers, with gradual release into stream channels, is a major source of annual flow in rivers.117 tkelley on DSK3SPTVN1PROD with PROPOSALS2 Transport of Sediment and Nutrients Ephemeral streams frequently contain boulders and woody debris that entrain and store loose, unconsolidated sediment during smaller precipitation events that is subsequently released during infrequent, high-magnitude precipitation events. Because of the abundance and distribution of headwater streams, sediment storage and transport by those streams can have a substantial cumulative effect on downstream waters; headwater streams are important sediment sources for maintaining channels and floodplains.118 Similarly, headwater streams are important sources of organic matter (organic carbon) that serves as a downstream food source for aquatic life 116 U.S. Environmental Protection Agency, The Ecological and Hydrological Significance of Ephemeral and Intermittent Streams in the Arid and Semi-Arid American Southwest.

VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 forms such as benthic macroinvertebrates and that enhances the fertility of agriculture on alluvial fans where some of the organic matter is deposited.119 Biological Connectivity Headwaters streams, including ephemeral streams, play an important role in the dispersal of genetic material and production and transport of food resources. For example, headwaters streams provide habitat that is critical for completion of one or more life-cycle stages of many aquatic and semiaquatic species capable of moving throughout water networks. These streams provide habitat for completion of complex life cycles. They also provide a refuge from predators, competitors, parasites, or adverse physical conditions in downstream waters.120 Because biological connections often result from passive transport of organisms or their products with water flow, biological connectivity often depends on hydrologic connectivity. Many living organisms, however, also can actively move with or against water flow; others disperse actively or passively over land by walking, flying, drifting, or ‘‘hitchhiking.’’ All of these organism-mediated connections form the basis of biological connectivity between headwater streams and downstream waters. Biological connections between upstream and downstream reaches can affect downstream waters via multiple pathways or functions. For organisms capable of significant upstream movement, headwater streams, including ephemeral and intermittent streams, can increase both the amount and quality of habitat available to those organisms. Many organisms require different habitats for different resources (e.g., food, spawning habitat, overwintering habitat), and thus move throughout the river network—both longitudinally and laterally—over their life cycles, with some requiring dry channels to complete part of their life cycle. Furthermore, dry stream channels can facilitate dispersal of aquatic invertebrates by serving as dispersal corridors for terrestrial adult forms. Headwater streams also provide food resources to downstream waters, especially in the form of terrestrial invertebrates that accumulate in intermittent and ephemeral streams during dry periods and are then transported downstream by storm flows PO 00000 119 Id. 120 Id. at 3–31 and 3–32. at ES–8. Frm 00018 Fmt 4701 during and after a precipitation event.121 Biogeochemical Processes There is strong evidence that headwater streams function as nitrogen sources (via export) and sinks (via uptake and transformation) for river networks. For example, one study estimated that rapid cycling of nutrients, including nitrogen, in small streams with no agricultural or urban impacts removed 20–40% of the nitrogen that otherwise would be delivered to downstream waters. Nutrients, including nitrogen, are necessary to support aquatic life, but excess nutrients lead to eutrophication and hypoxia, in which over-enrichment causes dissolved oxygen concentrations to fall below the level necessary to sustain most aquatic animal life in the stream and streambed. Thus, the influence of streams on nutrient loads can have significant repercussions for hypoxia in downstream waters.122 B. What specific rule changes are we proposing with respect to ephemeral streams? We propose to require that the permit applicant identify and map all ephemeral streams within the proposed permit and adjacent areas. The applicant must describe the physical and hydrologic characteristics of those streams in detail, as well as any associated vegetation in the riparian zone if one exists. In addition, the applicant must assess the biological condition of a representative sample of those ephemeral streams. See proposed 30 CFR 780.19(c)(6) and 784.19(c)(6). We also propose to require that the significance of ephemeral streams be evaluated during the permitting process as part of the determination of the probable hydrologic consequences of mining and the cumulative hydrologic impact assessment. See proposed 30 CFR 780.20, 780.21, 784.20, and 784.21. We further propose to specify that the backfilling and grading plan in the reclamation plan required by proposed 30 CFR 780.12(d) and 784.12(d) must include contour maps, cross-sections, or models that show in detail the anticipated final surface configuration, including drainage patterns, of the proposed permit area. Proposed 30 CFR 780.28(c)(1) and 784.28(c)(1) would require that the postmining drainage pattern, including ephemeral streams, be similar to the premining drainage pattern, with limited exceptions. 121 Id. 122 Id.

The riparian corridor requirement would not apply to prime farmland or when a corridor would be inconsistent with an approved postmining land use that is actually implemented before expiration of the revegetation responsibility period. Nor would it apply to stream segments that are buried beneath an excess spoil fill or a coal mine waste disposal facility.

They also indicate whether we propose to revise the rule text in each redesignated section or paragraph. The organizational changes serve several purposes, including— • Breaking up overly long sections and paragraphs into multiple shorter sections and paragraphs for ease of reference and improved comprehension. • Renumbering sections in the underground mining rules to align their numbering with the corresponding sections in the surface mining rules. This change would greatly improve ease of reference and the user-friendliness of our rules. • Moving permitting requirements from subchapter K (performance standards) to subchapter G to consolidate permitting requirements in subchapter G. • Restructuring subchapter G to better distinguish between baseline information requirements and reclamation plan requirements. • Removing redundant, suspended, and obsolete provisions. The following table is organized in the numerical order of the existing rule citations. It includes only those provisions of the existing regulations that we propose to move or remove.

In general, we drafted the proposed rule using plain language principles, consistent with section 501(b) of SMCRA, 30 U.S.C. 1251(a), which provides that regulations must be ‘‘concise and written in plain, understandable language,’’ and Executive Order 13563, which provides that our regulatory system ‘‘must ensure that regulations are accessible, consistent, written in plain language, and easy to understand.’’ 123 In addition, a June 1, 1998, Executive Memorandum on Plain Language in Government Writing 124 requires the use of plain language in all proposed and final rulemaking documents published after January 1, 1999. The Office of the Federal Register also encourages the use of plain language in writing regulations, as set forth in detail at www.plainlanguage.gov and associated links. Plain language requirements vary from one document to another, depending on the intended audience. Plain language documents have logical organization and easy-to-read design features like short sections, short sentences, tables, and lots of white space. They use common everyday words (except for necessary technical terms), pronouns, the active voice, and a question-and-answer format when feasible. The proposed rule and preamble use the pronouns ‘‘we,’’ ‘‘us,’’ and ‘‘our’’ to refer to OSMRE, and the pronouns ‘‘I,’’ ‘‘you,’’ and ‘‘your’’ to refer to a permit applicant or permittee. We avoid use of the word ‘‘shall’’ in the proposed rule and preamble, except in quoted material. Instead, we use ‘‘must’’ to indicate an obligation, ‘‘will’’ to identify a future event, and ‘‘may not’’ to convey a prohibition. We invite comment on how we could more fully incorporate plain language principles. version of these rules. See 53 FR 44356– 44363 (Nov. 2, 1988). We propose to revise paragraph (d)(1) of the existing rules by removing the phrase ‘‘the reclaimed site of’’ from the existing introductory language because the regulatory authority’s jurisdiction extends to the entire surface coal mining and reclamation operation, not just to the lands disturbed and reclaimed by the operation. Hence, any decision to terminate jurisdiction likewise should extend to the entire operation. We propose to improve the structure of the existing rule by placing the termination of jurisdiction requirements for initial program operations in paragraph (d)(1) and the requirements for permanent program operations in paragraph (d)(2). We also propose to add a provision to paragraph (d)(2)(ii) to reflect the proposed addition to 30 CFR part 800 of provisions concerning financial assurances for treatment of long-term discharges. In particular, we propose to allow the regulatory authority to terminate jurisdiction over all portions of a minesite and all aspects of the operation, except treatmentrelated facilities and obligations, once the permittee posts an acceptable financial assurance under proposed 30 CFR 800.18 to guarantee treatment of all long-term discharges. Termination of jurisdiction may not occur until all performance bonds for the remainder of the permit area are fully released. Our proposed rule would improve the efficiency of regulatory authorities by eliminating unnecessary inspections of 123 76 124 63 FR 3821 (Jan. 21, 2011). FR 31883–31886 (Jun. 10, 1998). VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 IX. How do we propose to revise specific provisions of our existing regulations? In this portion of the preamble, we discuss selected provisions of our proposed rule in the order in which the regulations that we propose to revise would appear in Title 30, Chapter VII of the Code of Federal Regulations. In general, we do not discuss proposed organizational changes (see Part VIII of this preamble for a listing of organizational changes), nonsubstantive editorial revisions (e.g., plain language changes, correction of grammatical errors, and syntax improvements), crossreference changes, or revisions of a minor nature. No substantive change in meaning is intended for proposed revisions made in accordance with plain language principles. A. Section 700.11(d): Termination and Reassertion of Jurisdiction The basis and purpose for our termination-of-jurisdiction rules is set forth in the preamble to the 1988 PO 00000 Frm 00032 Fmt 4701 Sfmt 4702 Existing text revised in proposed rule?

It also would eliminate the need for federal oversight of those sites and allow the property owner to acquire full control over the land. Continuing to conduct inspections of a fully-reclaimed minesite or of fullycompleted operations would divert scarce resources from unreclaimed sites and other regulatory program responsibilities. Because of the restructuring described above, we propose to redesignate existing paragraph (d)(2) as paragraph (d)(3). This paragraph provides that the regulatory authority must reassert jurisdiction if the termination was based upon fraud, collusion, or misrepresentation of a material fact. We also propose to revise this provision to clarify that it applies to both intentional and unintentional misrepresentations of a material fact, including the subsequent discovery of a discharge that requires treatment. Our proposed revision is consistent with the decision of the U.S. Court of Appeals for the District of Columbia Circuit that upheld our termination of jurisdiction rules.125 In addition, proposed paragraph (d)(4) would specify that the termination of jurisdiction provisions of proposed paragraphs (d)(1) and (2) do not apply to proposed 30 CFR 817.40, which contains the domestic water supply replacement requirements for underground mines, or to the structural damage repair or compensation requirements of 30 CFR 817.121(c)(2). Proposed paragraph (d)(4) is consistent with the decision of the U.S. District Court for the District of Columbia concerning termination of jurisdiction for the water replacement and subsidence damage correction obligations imposed on underground mines by section 720(a) of SMCRA.126 In that decision, the court held that those obligations are not subject to the termination of jurisdiction provisions of 30 CFR 700.11(d).127 Finally, we propose to revise existing 30 CFR 700.11(d)(1)(ii), which we propose to redesignate as 30 CFR 700.11(d)(2), to specify that the requirements of that paragraph also apply to coal exploration activities, as was intended when we first published our termination-of-jurisdiction rules in 1988.128 The phrase ‘‘or of a coal exploration site’’ was inadvertently omitted from the published text of 125 Nat’l Wildlife Fed’n v. Lujan, 950 F.2d 765, 770 (D.C. Cir. 1991); see also Brief for the Secretary at 27 n. 11. 126 30 U.S.C. 1309a(a). 127 Nat’l Mining Ass’n v. Babbitt, No. 95–0938, slip op. at 15 (D.D.C.

However, we invite comment on whether we should instead limit the scope of that requirement to termination of jurisdiction for coal exploration permits issued under 30 CFR 772.12. The rationale for a limitation of this nature is that, unlike coal exploration permits, coal exploration notices do not require regulatory authority approval and do not involve activities that substantially disturb the land surface. B. Section 701.5: Definitions This portion of the preamble discusses, in alphabetical order, each definition that we propose to add, remove, or revise. Acid Drainage We propose to revise the definition of this term to clarify that the same definition applies to the term ‘‘acid mine drainage.’’ We also propose to correct the terminology in the definition to comport with the terminology used in SMCRA. Specifically, we propose to replace the undefined term ‘‘surface coal mine and reclamation operation’’ with ‘‘surface coal mining and reclamation operations,’’ which is defined at section 701(27) of SMCRA,129 as well as in 30 CFR 700.5. Adjacent Area Proposed paragraph (a) would revise and broaden the existing definition of ‘‘adjacent area’’ to ensure that it includes all areas outside the proposed or actual permit area within which there is a reasonable possibility of adverse impacts from surface coal mining operations or underground mining activities, as applicable. The existing definition limits the adjacent area to areas where adverse impacts could reasonably be expected to occur and, for underground mining, to areas where subsidence is probable. Those limits are too restrictive because they effectively limit baseline data collection and monitoring to the area in which adverse impacts are almost certain to occur. If impacts occur outside that area, there will be no baseline data against which to evaluate those impacts. Therefore, we propose to revise the definition to include areas where impacts are reasonably possible, as determined by the regulatory authority on a sitespecific basis. The revised definition would emphasize that the term ‘‘adjacent area’’ is both site-specific and contextspecific. As in the existing definition, PO 00000 129 30 U.S.C. 1291(27). Frm 00033 Fmt 4701 Sfmt 4702 44467 the nature of the resource and the context in which the regulations use the term ‘‘adjacent area’’ would determine the size and dimensions of the adjacent area for that resource. Our regulations require that each permit application contain information concerning historic resources, fish and wildlife resources, surface water, groundwater, and geology for the proposed permit and adjacent areas. The size and boundaries of the adjacent area in the context of historic resources, which are stationary, may differ substantially from the size and boundaries of the adjacent area for surface water, for which flow patterns are determined by topography, and the size and boundaries of the adjacent area for groundwater, which has a migration pattern determined by geology. Proposed paragraph (b) would specify that the adjacent area for an underground mine includes both the area overlying the proposed underground workings and the area within a reasonable angle of draw 130 from the perimeter of the underground workings. This provision would ensure that the adjacent area includes all areas in which subsidence may reasonably occur. Proposed paragraph (c) would specify that, for all operations, the adjacent area also includes the area that might be affected physically or hydrologically by dewatering existing underground mine pools as part of surface or underground mining operations, plus the area that might be affected physically or hydrologically by mine pools that develop after cessation of mining activities. We considered adding another paragraph to specify that, in the context of surface-water resources, the adjacent area would include, at a minimum, the HUC–12 (U.S. Geological Survey 12digit Watershed Boundary Dataset) 131 watershed or watersheds in which the proposed or actual permit area is located. However, we decided against including that provision because HUC boundaries are fixed and do not vary with the location of the mining operation. Surface-water data collected from those portions of the HUC–12 watershed that are upgradient of the 130 The angle of draw is the angle between the outside edge of an underground mine void and the point on the surface to which subsidence may extend when the strata overlying the mine void collapse.

In addition, HUC–12 watersheds typically contain between 10,000 and 40,000 acres, which is much larger than the area necessary or appropriate to establish baseline conditions for most coal mines, which are only tens or hundreds of acres in size. We invite comment on whether the definition should prescribe a more appropriate minimum size for the adjacent area for surface-water resources and, if so, how that minimum size should be determined. For example, a 2002 OSMRE reference document on baseline data recommends that the adjacent area for surface water include both the surface-water runoff drainage area for the proposed operation and at least the next higher-order drainage area. Approximate Original Contour We propose to revise the definition of this term to explain its scope and to incorporate plain language principles. In concert with these changes, we propose to clarify that the term refers to the general surface configuration of the land within the permit area as it existed before any mining, not the configuration that existed immediately prior to the proposed or current operation. We intend this change to operate as a requirement that operations backfill and regrade previously mined areas to closely resemble the general surface configuration that existed before any mining, except as provided in 30 CFR 816.106 or 817.106. This approach is consistent with section 515(b)(2) of SMCRA,132 which requires that surface coal mining and reclamation operations be conducted so as to ‘‘restore the land affected to a condition capable of supporting the uses which it was capable of supporting prior to any mining . . . .’’ In ruling on the regulations implementing that provision of the Act, the U.S. District Court for the District of Columbia subsequently held that ‘‘[t]he use of the word ‘any’ indicates that Congress intended the operator to restore the land to the condition that existed before it was ever mined.’’ 133 Our proposed addition of the phrase ‘‘within the permit area’’ when referring to the general surface configuration is intended to clarify that determinations of approximate original contour must be 132 30 U.S.C. 1265(b)(2). re Permanent Surface Mining Regulation Litig.

Law Inst.) 20208. made based on the general surface configuration of the permit area, not the general surface configuration of the surrounding area. The proposed addition is consistent with section 701(2) of SMCRA,134 which defines ‘‘approximate original contour’’ as meaning ‘‘that surface configuration achieved by backfilling and grading of the mined area so that the reclaimed area . . . closely resembles the general surface configuration of the land prior to mining and blends into and complements the drainage pattern of the surrounding terrain . . . .’’ The statutory definition clearly applies the term ‘‘general surface configuration’’ only to the area that is mined and reclaimed; it does not extend to the surrounding area. Instead, with respect to the surrounding area, the statutory definition requires that the general surface configuration of the reclaimed area blend into and complement the drainage pattern of the surrounding terrain. Limiting the scope of the term ‘‘general surface configuration’’ to the mined and reclaimed area also is consistent with the discussion and diagrams in the legislative history of SMCRA. See H.R. Rep. No. 94–45, at 94 (1975). In addition, we propose to revise the definition to include an exception for excess spoil fills, consistent with a June 18, 1999, legal opinion from the Department of the Interior’s Office of the Solicitor. That opinion confirmed that the AOC restoration requirements of SMCRA do not apply to the construction of excess spoil fills, in part because the statutory definition of approximate original contour in section 701(2) of SMCRA 135 applies only to ‘‘that surface configuration achieved by backfilling and grading of the mined area.’’ Excess spoil fills are not part of the backfilling process and they are at least initially located outside the mined area. We also propose to add an exception for coal mine waste refuse piles because the same rationale applies to the construction of those piles. Furthermore, sections 515(b)(11) and 516(b)(4) of SMCRA 136 clearly envision the construction of permanent coal mine waste refuse piles on the land’s surface, but there is no requirement to restore the surface of that land to approximate original contour, nor would it be possible to do so. Instead, section 515(b)(11) of the Act 137 requires that the operation ‘‘assure the final contour of the waste pile will be compatible with 133 In VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 PO 00000 134 30 natural surroundings and that the site can and will be stabilized and revegetated according to the provisions of the Act.’’ Section 516(b)(4) 138 includes similar language for refuse piles associated with underground mines. We also propose to revise the definition to clarify that, consistent with the legislative history, the potentially confusing placement of the phrase ‘‘including any terracing or access roads’’ in the statutory definition does not mean that terraces and access roads must be regraded to the approximate original contour. As explained in the legislative history of the definition of approximate original contour, Congress added this phrase to clarify that the AOC restoration requirement does not prohibit the construction of terraces or the retention of access roads on backfilled areas.139 Therefore, we propose to add language stating that the requirements of the definition do not prohibit the approval of terracing under 30 CFR 816.102 or 817.102 or the retention of access roads under 30 CFR 816.150 or 817.150. Finally, we propose to replace the cross-references to 30 CFR 816.133 and 817.133 with cross-references to 30 CFR 780.24(b) and 784.24(b), respectively. This change reflects our proposal to move the relevant portions of 30 CFR 816.133 and 817.133 to 30 CFR 780.24(b) and 784.24(b), respectively. Backfill We propose to add a definition of ‘‘backfill’’ to clarify the difference between backfill, excess spoil fills, and thick overburden returned to the minedout area under 30 CFR 816.105, all of which have different permitting requirements and performance standards. We derived our proposed definition from the definition of ‘‘backfill’’ in A Dictionary of Mining, Mineral, and Related Terms (U.S. Bureau of Mines, 1968). However, we modified that definition by tailoring it to coal mining and the purpose stated in the first sentence of this discussion. Specifically, we propose to define ‘‘backfill,’’ when used as a noun, as the spoil and waste materials used to fill the void resulting from an excavation created for the purpose of extracting coal from the earth. When used as a verb, the term would refer to the process of filling that void. The definition also would include all materials used to restore the approximate original contour of the mined-out area.

Bankfull We propose to add a definition of this technical and scientific term because we use this term in our proposed regulations to more precisely fix the boundaries of stream buffer zones and riparian corridors and in our proposed stream restoration requirements. Under our proposed definition, bankfull would mean the water level or stage at which a stream, river, or lake is at the top of its banks and any further rise would result in water moving into the flood plain. The proposed definition parallels the one that appears in the National Weather Service glossary.140 tkelley on DSK3SPTVN1PROD with PROPOSALS2 Biological Condition We propose to add a definition of biological condition in conjunction with the new permitting requirements and performance standards concerning documentation, protection, and restoration of biological communities in streams. Specifically, we propose to define biological condition as a measure of the ecological health of a stream or segment of a stream as determined by the type, diversity, distribution, abundance, and physiological state of aquatic organisms and communities found in the stream or stream segment. The biological condition of a water body is the ultimate indicator of watershed health because aquatic organisms and communities reflect the cumulative conditions of all other watershed components and processes.141 Our proposed rule would require application of a multimetric biological assessment and taxonomic assessment protocol to determine biological condition. See, e.g., proposed 30 CFR 780.19(e) and 784.19(e). Multimetric indices include metrics such as species richness, complexity, and tolerance as well as trophic measures. They provide a quantitative comparison (often referred to as an index of biological or biotic integrity) of the ecological complexity of biological assemblages relative to a regionally-defined reference condition. For example, River Invertebrate Prediction and Classification System models quantify biological condition by comparing the observed taxa at a site to the taxa that would be expected to be present in the absence of human-caused stress.142 Our existing regulations do not specifically require collection of the baseline data necessary to determine the biological condition of streams. Consequently, the permit application often lacks specific descriptions of the aquatic community residing in streams within the permit and adjacent areas. The lack of baseline information on the biological condition of streams creates an impediment to determining whether the proposed operation has been designed to prevent material damage to the hydrologic balance outside the permit area, as required by sections 507(b) and 510(b)(3) of SMCRA.143 It also creates an impediment to evaluating whether the operation has been and is being conducted to minimize adverse impacts on fish, wildlife, and related environmental values, as required by sections 515(b)(24) and 516(b)(11) of SMCRA.144 Furthermore, preparation of a comprehensive cumulative hydrologic impact assessment is not always possible if the permit application does not include information on the biological condition of streams. While the information sometimes may be available from the agencies responsible for implementing the Clean Water Act, those agencies generally do not assess the cumulative loading of substances legally discharged into the receiving stream until the stream becomes impaired. Cumulative Impact Area Sections 507(b)(11) and 510(b)(3) of SMCRA 145 require that the regulatory authority prepare an assessment of the probable cumulative impact of all anticipated mining in the area upon the hydrology of the general area. In 1983, we adopted a definition of cumulative impact area to identify both the extent of the area that must be included in this evaluation and the scope of the term ‘‘anticipated mining.’’ 146 The first sentence of the 1983 definition mentions only anticipated mining, while the second sentence includes existing operations in the list of the types of operations encompassed by the term ‘‘anticipated mining.’’ We propose to resolve this inconsistency by replacing the term ‘‘anticipated mining’’ with ‘‘existing and anticipated mining’’ or its equivalent. 140 See https://forecast.weather.gov/ glossary.php?word=BANKFULL (last accessed January 16, 2015). 141 https://water.epa.gov/polwaste/nps/watershed/ biotic.cfm (last accessed June 8, 2015).

Discharges of water from underground mines can cause material damage to the hydrologic balance outside the permit area, as demonstrated by a 2010 incident in which water discharged from an underground mine resulted in a golden algae bloom in Dunkard Creek in West Virginia and Pennsylvania that caused a major fish kill.147 Our revised definition would clarify that the cumulative impact area includes the area within which the proposed or actual operation may interact with the impacts of all existing and anticipated surface and underground coal mining operations. We propose to restructure the definition for clarity. Proposed paragraphs (a) through (c) would specify the areas that must be included in the cumulative impact area. Proposed paragraph (a) would require that the cumulative impact area include the actual or proposed permit area. The addition of the ‘‘actual or proposed’’ language reflects the fact that the cumulative impact area is a concept that applies both before and after permit issuance. Proposed paragraph (b) would require that the cumulative impact area include the HUC–12 (U.S. Geological Survey 12digit Watershed Boundary Dataset) 148 watershed or watersheds in which the actual or proposed permit area is located. We propose to add this provision to establish a bright-line standard for the minimum size of the cumulative impact area. For operations that straddle a ridgeline or other watershed boundary, the cumulative impact area must include, at a minimum, the HUC–12 watershed on each side of the ridgeline or other boundary. Proposed paragraph (c) would provide that, in addition to the areas specified in proposed paragraphs (a) and (b), the cumulative impact area must include any other area within which impacts resulting from an actual or proposed surface or underground coal mining operation may interact with the impacts of all existing and anticipated surface and underground coal mining on surface-water and groundwater systems, including the impacts that existing and 147 Reynolds, Louis.

Proposed paragraph (c)(4) would specify that ‘‘anticipated mining’’ includes any proposed surface or underground mining operation for which a person has submitted a request for an authorization, certification, or permit under the Clean Water Act. Inclusion of proposed operations for which the Clean Water Act authorization process has begun would assist in preparation of a more comprehensive analysis on the part of both the permit applicant or permittee and the regulatory authority. Proposed paragraph (c)(5) would modify paragraph (d) of the existing definition to clarify that anticipated mining includes all lands for which a resource recovery and protection plan has been either approved or submitted to and reviewed by the authorized officer of the Bureau of Land Management under 43 CFR 3482.1(b). The added language would clarify the point at which lands containing leased Federal coal must be included within the cumulative impact area. Proposed paragraph (c)(6) would specify that anticipated mining includes, for underground mines, all areas of contiguous coal reserves adjacent to an existing or proposed underground mine that are owned or controlled by the applicant. This addition is appropriate because, barring significant changes in economic or regulatory conditions, the mine very likely will be extended into those reserves in the future. tkelley on DSK3SPTVN1PROD with PROPOSALS2 Ecological Function We propose to add a definition of this term in concert with our proposal to require that permittees restore the ecological function of the segments of perennial and intermittent streams through which they mine. Ecological function includes physical parameters, biological parameters, and a consideration of physical and biological interactions as nutrients and energy are collected and transferred down the stream continuum.149 Specifically, we propose to define this term as including the role that the stream plays in 149 Vannote, R. L., G. W. Minshall, K. W. Cummins, J. R. Sedell, and C. E. Cushing. The river continuum concept. (1980) Can. J. Fish. Aquat. Sci. 37:130–137.

It also includes the ability of the stream ecosystem to retain and transform inorganic materials needed for biological processes into organic forms (forms containing carbon) and to oxidize those organic molecules back into elemental forms through respiration and decomposition. Finally, the term includes the role that the stream plays in the life cycles of plants, insects, amphibians (especially salamanders), reptiles, fish, birds, and mammals that either reside in the stream or depend upon it for habitat, reproduction, food, water, or protection from predators. The proposed definition is based upon a functional assessment guidebook that the U.S. Army Corps of Engineers developed for ephemeral and intermittent streams in central Appalachia.150 The biological condition of a stream is one measure of its ecological function. Ephemeral Stream We propose to redefine ‘‘ephemeral stream’’ in a manner that is substantively identical to the manner in which the U.S. Army Corps of Engineers defines that term in Part F of the 2012 reissuance of the nationwide permits under section 404 of the Clean Water Act. See 77 FR 10184, 10288 (Feb. 21, 2012). Adoption of a substantively identical definition would promote consistency in application and interpretation of that term under both SMCRA and Clean Water Act programs. We invite comment on whether the definition in the final rule should include language specifying that the U.S. Army Corps of Engineers has the ultimate authority to determine the point at which an ephemeral stream becomes an intermittent stream or a perennial stream and vice versa. Further, if the final rule includes language to that effect, we invite comment on whether the definition also should provide that any determination that the Corps makes concerning these transition points will be controlling for purposes of SMCRA regulatory programs. Commenters should discuss the applicability of two SMCRA provisions in this context. First, section 702(a) of SMCRA 151 provides that ‘‘[n]othing in this Act shall be construed as superseding, amending, modifying, or repealing’’ the Clean Water Act, any rule 150 ‘‘Operational Draft Regional Guidebook for the Functional Assessment of High-Gradient Ephemeral and Intermittent Headwater Streams in Western West Virginia and Eastern Kentucky.’’ ERDC/EL TR–10–11, July 2010, U.S. Army Engineer Research and Development Center, Vicksburg, MS. 151 30 U.S.C. 1292(a). PO 00000 Frm 00036 Fmt 4701 Sfmt 4702 or regulation adopted under the Clean Water Act, or any state laws enacted pursuant to the Clean Water Act. Second, section 505(b) of SMCRA 152 provides that any provision of any state law or regulation may not be construed to be inconsistent with SMCRA if it ‘‘provides for more stringent land use and environmental controls and regulations of surface coal mining and reclamation operation[s] than do the provisions of this Act or any regulation issued pursuant thereto.’’ In other words, should our regulations allow states to adopt and apply stream definitions in a manner that would protect a greater length of stream than would the Corps determinations? The primary difference between our existing definition and the Corps definition that we propose to adopt concerns the treatment of snowmelt. Our existing definition classifies streamflow in response to the melting of snow and ice as an ephemeral stream, whereas the Corps definition is silent on this point. The preamble to the Corps definition notes that the Corps declined to accept a recommendation from a commenter that streamflow resulting from snowmelt be classified as an ephemeral stream. The preamble explains that, while snowmelt may contribute to the flow of ephemeral streams, snowmelt also contributes to the flow of intermittent and perennial streams, especially in areas with deep snow packs. The preamble further states that the definition appropriately focuses on the duration of flow and that melting snow should not be considered a precipitation event because the development of a snowpack occurs over the course of a winter season. See 77 FR 10184, 10262 (Feb. 21, 2012). Excess Spoil Our existing rules define excess spoil as spoil material disposed of in a location other than the mined-out area. The definition excludes spoil used to achieve the approximate original contour or to blend the mined-out area with the surrounding terrain in nonsteep slope areas. However, the existing definition is silent with respect to the characterization of spoil placed on the mined-out area in excess of the amount of spoil needed to restore the approximate original contour. We propose to revise the definition of excess spoil and add a definition of backfill to more clearly differentiate among backfill, material placed in excess spoil fills, and thick overburden returned to the mined-out area under 30 CFR 816.105. 152 30 E:\FR\FM\27JYP2.SGM U.S.C. 1255(b). 27JYP2 tkelley on DSK3SPTVN1PROD with PROPOSALS2 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules Specifically, we propose to define excess spoil as including all spoil material disposed of in a location other than the mined-out area within the permit area. The definition also would include all spoil material placed above the approximate original contour within the mined-out area as part of the continued construction of an excess spoil fill with a toe located outside the mined-out area. The added language concerning continuation of an excess spoil fill onto the mined-out area is intended to ensure that the fill is constructed using consistent standards for the entire structure so that the fill is uniformly stable. The revised definition would retain the clarification that spoil used to restore the approximate original contour of the mined-out area is not excess spoil. It also would retain the exception for spoil used to blend the mined-out area with the surrounding terrain in non-steep slope areas. We propose to add a new provision clarifying that the definition does not include spoil material placed within the mined-out area in accordance with the thick overburden provisions of 30 CFR 816.105(b)(1), even if it exceeds the amount needed to restore the approximate original contour, unless that material is a continuation of an excess spoil fill. This provision would eliminate any ambiguity regarding thick overburden treatment in the existing rules and is consistent with the thick overburden provisions of section 515(b)(3) of SMCRA,153 which makes no reference to the excess spoil provisions of section 515(b)(22) of SMCRA 154 in establishing requirements for the placement and grading of spoil within the mined-out area. In summary, under our proposed rule, the general backfilling and grading requirements of 30 CFR 816.102 or 817.102 would apply to all spoil placed in the mined-out area for the purpose of restoring the approximate original contour within the parameters of those rules. The thick overburden performance standards of 30 CFR 816.105(b) would apply to all spoil placed in or on the mined-out area in excess of the approximate original contour parameters established in 30 CFR 816.102(a)(1) or 817.102(a)(1), with the exception of spoil that is a continuation of an excess spoil fill with a toe located outside the mined-out area. For all operations, the excess spoil disposal requirements of 30 CFR 816.71 and 816.74 or 817.71 and 817.74 would govern the construction of excess spoil 153 30 U.S.C. 1265(b)(3). 154 30 U.S.C. 1265(b)(22).

Fill We propose to define the term ‘‘fill’’ to clarify the meaning of this term as it is used in the context of surface coal mining operations under SMCRA and to differentiate this term from the term ‘‘fill material’’ as used and defined in the regulations implementing section 404 of the Clean Water Act.155 See 33 CFR 323.2(e) and 40 CFR 232.2. Our proposed definition would include only permanent, non-impounding structures constructed for the purpose of disposing of excess spoil and solid coal mine waste, consistent with the common usage of this term in the context of coal mining operations. It would not include any impoundments or temporary structures. It has no relationship to whether construction of the excess spoil or coal mine waste disposal facility involves the discharge of dredged or fill material into waters of the United States under the Clean Water Act. Fugitive Dust We propose to remove this definition because it defines a term that we no longer use in our regulations. See the preamble discussions of proposed 30 CFR 780.12(f) and our proposed removal of existing 30 CFR 780.15 and 784.26 for further explanation. Groundwater This definition would replace the existing definition of the term ‘‘Ground water.’’ We propose to replace the words ‘‘ground water’’ with the single word ‘‘groundwater’’ throughout our regulations for internal consistency. We also propose to revise the definition to add clarity and to more closely resemble generally-accepted definitions in scientific and trade publications. Specifically, our proposed definition is adapted from Freeze and Cherry (1979) 156 and a publication entitled ‘‘The ABCs of Aquifers.’’ 157 Under the proposed rule, ‘‘groundwater’’ would mean subsurface water located in those portions of soils and geologic formations that are completely saturated with water; i.e., those zones where all the pore spaces and rock fractures are completely filled with water.

Perched aquifers occur where subsurface water collects above unsaturated rock formations as a result of a discontinuous impermeable layer.158 Perched aquifers are fairly common in glacial sediments.159 They also occur in other sedimentary formations where weathered layers, ancient soils or caliche (found in arid or semiarid areas) have created impermeable zones.160 Perched aquifers are often removed by surface coal mining operations; they need not be restored unless restoration is needed to prevent material damage to the hydrologic balance outside the permit area. Highwall Remnant We propose to remove this definition because the term ‘‘highwall remnant’’ is self-explanatory and because the existing definition inappropriately limits the term to remining operations. There is no basis under SMCRA for this limitation. Hydrologic Balance The existing definition of hydrologic balance mentions water quality, but focuses on water quantity, water flow and movement, water storage, and changes in the physical state of water. We propose to revise this definition to include provisions relating to water quality and the impact of water quality on the biological condition of streams. Specifically, we propose to add language stating that the term includes interactions that result in changes in the chemical composition or physical characteristics of groundwater and surface water, which may affect the biological condition of streams and other water bodies. The proposed revisions are intended to clarify that water quality is as important as water quantity. They are consistent with the manner and context in which the term ‘‘hydrologic balance’’ appears in SMCRA. Sections 507, 508, 510, 515, and 516 of SMCRA161 contain repeated references to water quality considerations.

We invite comment on whether the definition in the final rule should include language specifying that the U.S. Army Corps of Engineers has the ultimate authority to determine the point at which an ephemeral stream becomes an intermittent stream or a perennial stream and vice versa. Further, if the final rule includes language to that effect, we invite comment on whether the definition also should provide that any determination that the Corps makes concerning these transition points will be controlling for purposes of SMCRA regulatory programs. Commenters should discuss the applicability of two SMCRA provisions in this context. First, section 702(a) of SMCRA 162 provides that ‘‘[n]othing in this Act shall be construed as superseding, amending, modifying, or repealing’’ the Clean Water Act, any rule or regulation adopted under the Clean Water Act, or any state laws enacted pursuant to the Clean Water Act. Second, section 505(b) of SMCRA 163 provides that any provision of any state law or regulation may not be construed to be inconsistent with SMCRA if it ‘‘provides for more stringent land use and environmental controls and regulations of surface coal mining and reclamation operation[s] than do the provisions of this Act or any regulation issued pursuant thereto.’’ In other words, should our regulations allow states to adopt and apply stream definitions in a manner that would protect a greater length of stream than would the Corps determinations? Our existing definition has two principal differences with the Corps’ definition that we propose to adopt. First, paragraph (b) of our existing definition of an intermittent stream would not consider a stream with a base flow resulting from the melting of a 162 30 163 30 U.S.C. 1292(a). U.S.C. 1255(b). VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 snowpack to be an intermittent stream because the snowpack does not lie below the local water table and because snowmelt is not considered groundwater. However, the preamble to the definition of ‘‘ephemeral stream’’ that the Corps adopted as part of the 2012 reissuance of the nationwide permits under section 404 of the Clean Water Act states that snowmelt contributes to the flow of intermittent and perennial streams, especially in areas with deep snow packs, and that melting snow should not be considered a precipitation event because the development of a snowpack occurs over the course of a winter season. See 77 FR 10184, 10262 (Feb. 21, 2012). In essence, the preamble discussion would allow a stream originating from a melting snowpack to be considered an intermittent stream even though the definition of ‘‘intermittent stream’’ requires groundwater as the source of base flow. We invite comment on whether we should revise our proposed definition of ‘‘intermittent stream’’ to include language consistent with the discussion of snowmelt in the preamble to the Corps’ definition of ‘‘ephemeral stream.’’ Second, we propose to remove paragraph (a) of our existing definition of ‘‘intermittent stream.’’ That paragraph automatically designates any stream or reach of a stream that drains a watershed of at least one square mile as an intermittent stream. This provision is inconsistent with generally-accepted stream classification systems because it is based on watershed size rather than streambed characteristics and duration and source of streamflow. For example, one study in West Virginia found perennial streams with a median drainage area of less than 0.1 square mile and intermittent flows with a median drainage area of 14.5 acres, both of which are much smaller than one square mile (640 acres).164 On the other hand, ephemeral streams in arid regions can have drainage areas of dozens of square miles. Furthermore, the existing definition could be construed as meaning that all streams with a watershed greater than one square mile are intermittent, even when they would otherwise be classified as perennial streams. We originally adopted the watershedsize criterion because Alabama and Illinois found it easy to administer and apply and because we believed that a 164 Paybins, Katherine M., ‘‘Flow Origin, Drainage Area, and Hydrologic Characteristics for Headwater Streams in the Mountaintop Coal-Mining Region of Southern West Virginia, 2000–2001.’’ WaterResources Investigations Report 02–4300, U.S. Department of the Interior Geological Survey. PO 00000 Frm 00038 Fmt 4701 Sfmt 4702 stream with a watershed of that size has a potential for flood volumes that would necessitate application of the streamchannel diversion requirements.165 As explained below, we no longer find either reason compelling. First, the easy-to-administer argument is valid only if the watershed-size criterion was the only criterion for determining whether a stream is intermittent. However, that is not the case. The existing definition also provides that any stream that is below the local water table for at least part of the year and obtains its flow from both surface runoff and groundwater discharge is an intermittent stream. As discussed above, both perennial and intermittent streams often have watersheds much smaller than one square mile, so the permit applicant and the regulatory authority still must conduct a hydrological evaluation of streams in watersheds smaller than one square mile to determine whether they are nonetheless intermittent or perennial based on the source of streamflow. With respect to the second reason, the possibility of flood damage from diversion of an otherwise-ephemeral stream with a watershed greater than one square mile does not justify retention of a definition of intermittent stream that is not consistent with definitions used by the U.S. Army Corps of Engineers and the scientific community. The preamble to 30 CFR 816.43 and 817.43 requests comment on whether we should revise our regulations governing diversions to adopt design requirements based on whether the diversion is permanent or temporary rather than on whether the flow being diverted is perennial, intermittent, or ephemeral. Land Use We propose to revise the introductory text of this definition for clarity and to add a sentence specifying that the individual land use categories in the definition are the categories to be used in the regulatory program. In addition, we propose to remove the third sentence of the first paragraph of the existing definition. That sentence reads: ‘‘Changes of land use from one of the following categories to another shall be considered as a change to an alternative land use which is subject to approval by the regulatory authority.’’ This sentence is inconsistent with the revisions that we are proposing to 30 CFR 780.24 and 784.24, as discussed later in this preamble. Under our proposed revisions to those rules, a proposed postmining 165 44 E:\FR\FM\27JYP2.SGM FR 14932 (Mar. 13, 1979). 27JYP2 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules land use that differs from the actual premining land use would not require approval as a higher or better use if the land as it existed before mining was already capable of supporting that use in its existing condition. Moreover, this change would better implement section 515(b)(2) of SMCRA,166 which provides that the permittee must ‘‘restore the land affected to a condition capable of supporting the uses [not just the use that existed immediately prior to mining] which it was capable of supporting prior to any mining, or higher or better uses of which there is reasonable likelihood.’’ This statutory language indicates that the alternative postmining land use requirements in our rules should apply only when the applicant or permittee proposes a higher or better use, not a use that the land was capable of supporting before mining. We also propose to revise the definition of cropland in paragraph (a) of the definition of land use to more accurately and inclusively describe the types of plantings and planting settings associated with that land use category. Specifically, we propose to include commercial nursery plantings, vegetables, fruits, nuts, and other plants typically grown in fields, orchards, vineyards, and similar settings involving intensive agricultural uses. tkelley on DSK3SPTVN1PROD with PROPOSALS2 Material Damage We propose to revise a cross-reference to 30 CFR 784.20 in this definition to be consistent with our proposed redesignation of existing § 784.20 as § 784.30. We propose no other changes to this definition, which applies only in the context of damage that occurs as a result of subsidence caused by underground mining operations. It is not related to, nor does it replace or supersede, the definition of ‘‘material damage to the hydrologic balance outside the permit area’’ or requirements related to that definition. Material Damage to the Hydrologic Balance Outside the Permit Area Our existing regulations do not define this term, which, as discussed below, is central to one of the principal findings required for approval of a permit application. Section 510(b)(3) of SMCRA 167 specifies that the regulatory authority may not approve a permit application unless the regulatory authority has ‘‘made an assessment of the probable cumulative impact of all anticipated mining in the area on the hydrologic balance specified in section 507(b).’’ This assessment is generally referred to as the cumulative hydrologic impact assessment (CHIA). Section 507(b)(11) of SMCRA,168 the pertinent part of the SMCRA section referenced in the quote above, requires that each permit application include— a determination of the probable hydrologic consequences of the mining and reclamation operations, both on and off the mine site, with respect to the hydrologic regime, quantity and quality of water in surface and ground water systems including the dissolved and suspended solids under seasonal flow conditions and the collection of sufficient data for the mine site and surrounding areas so that an assessment can be made by the regulatory authority of the probable cumulative impact of all anticipated mining in the area upon the hydrology of the area and particularly upon water availability. Section 510(b)(3) also specifies that the regulatory authority may not approve a permit unless the application affirmatively demonstrates and the regulatory authority finds in writing that the proposed operation ‘‘has been designed to prevent material damage to the hydrologic balance outside the permit area.’’ However, SMCRA does not define or explain the meaning of the term ‘‘material damage to the hydrologic balance outside the permit area.’’ Our existing regulations do not fully integrate the implementation of sections 507(b)(11) and 510(b)(3) of SMCRA 169 because they do not require collection of sufficient data for the proposed permit area and surrounding areas to prepare an adequate CHIA and because they do not define or establish criteria for determining material damage to the hydrologic balance outside the permit area. In particular, they do not specifically require data related to the biological community in streams or data comprised of a complete suite of the chemical and physical constituents and properties of groundwater and surface water. Without sound baseline information on surface-water and groundwater quality and quantity and the biological communities in streams, the regulatory authority cannot prepare an adequate cumulative hydrologic impact assessment or determine whether the proposed mining operation has been designed to prevent material damage to the hydrologic balance outside the permit area. This proposed rule is intended to correct this problem by adding a definition of the term ‘‘material damage to the hydrologic balance outside the permit area’’ and by refining and expanding baseline data requirements for permit applications, which we discuss later in this preamble in connection with proposed 30 CFR 780.19. These two changes would promote more effective implementation of sections 507(b)(11) and 510(b)(3) of SMCRA 170 and, in combination with the improved monitoring requirements in proposed 30 CFR 780.23 and 816.35 through 816.37, would better protect streams. In developing a definition of ‘‘material damage to the hydrologic balance outside the permit area,’’ we looked to our previous statements on this matter in preambles to our regulations concerning hydrology and geology. We also examined other provisions of SMCRA and the legislative history of section 510(b)(3) of SMCRA.171 Several commenters on a proposed rule on hydrology and geology that we published on June 25, 1982 (47 FR 27712), requested that we add a definition of material damage to the hydrologic balance outside the permit area to our regulations. However, the preamble to the final rule that we adopted in response to that proposed rule explains that we declined the requests for a definition ‘‘because the gauges for measuring material damage may vary from area to area and from operation to operation. OSM[RE] has not established fixed criteria, except for those established under §§ 816.42 and 817.42 related to compliance with water-quality standards and effluent limitations.’’ 172 The preamble provides no further explanation of that statement, but it does state that we agreed with commenters that ‘‘regulatory authorities should establish criteria to measure material damage.’’ 173 In the 30 years since we published that preamble, very few states have adopted a definition or established programmatic criteria for material damage to the hydrologic balance outside the permit area. Therefore, adoption of a federal definition of material damage to the hydrologic balance outside the permit area is both necessary and appropriate to ensure effective and consistent application of that term. In addition, the absence of either a federal definition of or criteria for material damage to the hydrologic balance outside the permit area has made it difficult for us to determine whether states are effectively implementing their counterparts to 30 CFR 773.15(c) and section 510(b)(3) of 170 30 U.S.C. 1257(b)(11) and 1260(b)(3).

The term first appears in H.R. 2, the House version of the legislation that ultimately became SMCRA. Earlier unsuccessful precursors to SMCRA used the phrase ‘‘significant irreparable offsite damage,’’ which also was undefined. In explaining the change in terminology, the Committee report states only that the previous phrase was ‘‘deleted in favor of language that specifies that the mine is to be designed to prevent damage to the hydrologic balance outside the permit area.’’ 177 There is no discussion of whether, in making this substitution, Congress intended to eliminate the elements of ‘‘significant’’ and ‘‘irreparable’’ from the standard, or whether the new language is merely a nonsubstantive change in wording. When we declined to define ‘‘material damage to the hydrologic balance outside the permit area’’ in 1983, we noted that the only fixed criteria that we established at the time for such damage were those included in ‘‘§§ 816.42 and 817.42 related to compliance with water-quality standards and effluent limitations.’’ However, we do not think it appropriate to interpret this preamble statement as meaning that any exceedance of water quality standards or effluent limitations, no matter how minor and no matter what the cause, would constitute material damage to the hydrologic balance outside the permit area. Our proposed definition reflects our conclusion that the mere possibility of an acid or toxic discharge or other type of degradation of surface water or groundwater does not provide an adequate basis for permit denial on the grounds that it would not prevent material damage to the hydrologic balance outside the permit area. Instead, for a permit to be denied on this basis, there must be some probability of the formation of acid or toxic mine drainage that may continue after the completion of mining and land reclamation, and there must be a reasonable likelihood that the reclamation plan proposed by the applicant will not be capable of preventing the formation of that drainage. We base our conclusion, in part, on our prior statements relating to the preparation of cumulative hydrologic impact assessments. We find these statements to be particularly instructive because section 510(b)(3) of SMCRA,178 which refers to those assessments, also contains the term ‘‘material damage to the hydrologic balance outside the permit area.’’ In particular, in the preamble to the 1983 version of 30 CFR 780.21(g), we stated that the cumulative hydrologic impact assessment must be ‘‘accomplished in an environmentally and scientifically sound fashion,’’ and that it ‘‘cannot reasonably be extended to include remote and speculative impacts.’’ 179 Instead, we determined that the assessment ‘‘should be based upon those impacts that have a reasonable likelihood for occurring and which are sufficiently defined to enable the regulatory authority to reach a decision.’’ 180 That preamble, however, does not define or otherwise clarify the meaning of ‘‘reasonable likelihood’’ and ‘‘sufficiently defined.’’ Thus, we looked to other sources, including related provisions of SMCRA, to provide some guidance as to what material damage to the hydrologic balance outside the permit area means in the context of water quality parameters for which there are no effluent limitations. Section 508(a)(13) of SMCRA 181 requires that each reclamation plan include— [A] detailed description of the measures to be taken during the mining and reclamation process to assure the protection of: (A) the quality of surface and ground water systems, both on- and off-site, from adverse effects of the mining and reclamation process; (B) the rights of present users to such water; and (C) the quantity of surface and ground water systems, both on- and off-site, from adverse effects of the mining and reclamation process or to provide alternative sources of water where such protection of quantity cannot be assured[.] In 1979, we noted that this provision of SMCRA, along with sections 102, 510(b)(3), and 522(a) through (d) of the Act,182 ‘‘requires that mining not be permitted at all, if reclamation cannot be feasibly performed to protect water 178 30 179 48 174 30 U.S.C. 1260(b)(3).

Thus, to the extent that mining would result in unacceptable discharges of sulfates and total dissolved solids, the regulatory authority should not issue permits for the areas involved.’’ 183 As that passage from the 1979 preamble indicates, we have never interpreted section 508(a)(13) of SMCRA 184 to operate as an absolute prohibition on mining operations that would have adverse effects on the hydrologic balance. In our judgment, this provision also does not supersede the performance standards in sections 515 and 516 of SMCRA,185 which recognize that mining may cause some adverse effects on surface water and groundwater, particularly within the permit area. See, e.g., section 515(b)(10) of SMCRA,186 which provides that surface coal mining and reclamation operations must be conducted ‘‘to minimize the disturbances to the prevailing hydrologic balance at the mine-site and in associated offsite areas and to the quality and quantity of water in surface and ground water systems both during and after surface coal mining operations and during reclamation.’’ Significantly, this provision of SMCRA uses the term ‘‘minimize’’ rather than ‘‘prevent’’ when describing the standard that surface coal mining and reclamation operations must meet in this context. With these considerations in mind, we have designed our proposed definition of material damage to the hydrologic balance outside the permit area to protect all designated uses of surface water and all existing and reasonably foreseeable uses of surface water and groundwater outside the permit area. Specifically, in relevant part, under our proposed definition, ‘‘material damage to the hydrologic balance outside the permit area’’ would mean any adverse impact from surface or underground mining operations on the quantity or quality of surface water or groundwater, or on the biological condition of a perennial or intermittent stream, that would preclude any designated surface-water use under sections 101(a) and 303(c) of the Clean Water Act 187 or any existing or reasonably foreseeable use of surface water or groundwater outside the permit area. Our proposed definition is consistent with our statement in the 1979 preamble that mining should not be permitted at all if reclamation cannot feasibly protect water uses.188 E:\FR\FM\27JYP2.SGM 27JYP2 tkelley on DSK3SPTVN1PROD with PROPOSALS2 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules States have developed multimetric bioassessment protocols for use in determining the biological condition of streams and other surface waters for purposes of preparing the water quality inventory required under section 305(b) of the Clean Water Act. Multimetric indices include metrics such as species richness, complexity, and tolerance as well as trophic measures. They provide a quantitative comparison (often referred to as an index of biological or biotic integrity) of the ecological complexity of biological assemblages relative to a regionally-defined reference condition. Under proposed 30 CFR 780.19(e)(2) and 784.19(e)(2), states would be required to establish a correlation between these index values and each designated use under sections 101(a) and 303(c) of the Clean Water Act, as well as any other existing or reasonably foreseeable uses. In other words, we anticipate that the SMCRA regulatory authority, with assistance from the appropriate Clean Water Act agencies, will define the range of index values required to support each existing, reasonably foreseeable, and designated use of the stream segment in question. Any change in the biological condition of the stream or other surface-water body, as documented by index scores resulting from use of the bioassessment protocol for monitoring purposes, that would preclude attainment or maintenance of an existing, reasonably foreseeable, or designated use of surface water would constitute material damage to the hydrologic balance outside the permit area if the change in scores is a result of the SMCRA operation. We seek comment on the effectiveness of using index scores from bioassessment protocols to ascertain impacts on existing, reasonably foreseeable, or designated uses. If you disagree with the use of index scores from bioassessment protocols, please identify a viable and scientifically-valid alternative. The regulations implementing the Clean Water Act define ‘‘existing uses’’ as ‘‘those uses actually attained in a waterbody on or after November 28, 1975, whether or not they are included in the water quality standards.’’ See 40 CFR 131.3. In the context of this proposed definition, we intend to interpret the term ‘‘existing uses’’ in a similar fashion; i.e., existing uses would be those uses in existence at the time of preparation of the permit application, regardless of whether those uses are designated uses. Alternatively, we may replace the term ‘‘existing uses’’ with ‘‘premining uses’’ for purposes of clarity. We invite comment on this topic. VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 The second part of the proposed definition of ‘‘material damage to the hydrologic balance outside the permit area’’ provides that this term means any adverse impact from surface coal mining and reclamation operations or from underground mining activities, including any adverse impacts from subsidence that may occur as a result of underground mining activities, on the quality or quantity of surface water or groundwater, or on the biological condition of a perennial or intermittent stream, that would impact threatened or endangered species, or have an adverse effect on designated critical habitat, outside the permit area in violation of the Endangered Species Act of 1973, 16 U.S.C. 1531 et seq. This provision is intended to ensure compliance with both the Endangered Species Act and the fish and wildlife protection provisions of sections 515(b)(24) and 516(b)(11) of SMCRA. We also are considering alternative language for the second part of the definition. That alternative would replace the phrase ‘‘that would impact threatened or endangered species, or have an adverse effect on designated critical habitat, outside the permit area in violation of the Endangered Species Act of 1973, 16 U.S.C. 1531 et seq.’’ with ‘‘that would jeopardize the continued existence of threatened or endangered species, or result in the destruction or adverse modification of designated critical habitat, outside the permit area in violation of the Endangered Species Act of 1973, 16 U.S.C. 1531 et seq.’’ The second alternative would parallel the language of existing and proposed 30 CFR 816.97(b) and 817.97(b). State water quality standards and associated water quality criteria provide a starting point for establishment of material damage criteria under SMCRA for surface waters, but they are not the endpoint. SMCRA material damage criteria must be no less stringent than Clean Water Act water quality standards and criteria in all cases, but, in some situations, they may need to be more stringent to protect unique uses or to comply with the Endangered Species Act. In addition, the SMCRA regulatory authority may need to establish numerical material damage criteria for parameters of concern for which there are no numerical water quality standards or water quality criteria under the Clean Water Act. The Clean Water Act does not apply to groundwater, so the SMCRA regulatory authority would need to use best professional judgment to establish material damage criteria to protect existing and reasonably foreseeable uses of groundwater. Material damage PO 00000 Frm 00041 Fmt 4701 Sfmt 4702 44475 criteria for groundwater also would need to take into consideration the needs of any threatened or endangered species. The proposed definition does not differentiate between permanent or long-term impacts and temporary or short-term impacts. Any impact that would preclude a designated, existing, or reasonably foreseeable use of surface water outside the permit area, or an existing or reasonably foreseeable use of groundwater outside the permit area, would constitute material damage to the hydrologic balance, regardless of the duration of the impairment. Isolated noncompliant discharges would not be considered material damage unless those discharges are of a magnitude sufficient to preclude a protected use. We invite comment on whether the definition should exclude temporary adverse impacts if the permit applicant can demonstrate that there will be no long-term adverse impacts after mining is completed. Nothing in the proposed definition is intended to supersede the water supply replacement provisions of sections 717 and 720 of SMCRA.189 In other words, material damage to the hydrologic balance outside the permit area would not exist solely because the operation destroys or damages protected water supplies, provided that the permittee replaces those supplies in accordance with applicable regulatory program requirements (i.e., proposed 30 CFR 816.40 or 817.40) and the definition of ‘‘replacement of water supply’’ in 30 CFR 701.5. The definition would apply to adverse impacts from subsidence resulting from underground mining operations and to other adverse impacts resulting from underground mining operations; e.g., dewatering a stream by mining through a fracture zone or dewatering an aquifer or saturated zone that serves as a water supply for legitimate uses. It would not be limited to the impacts of surface mining activities or the impacts of activities conducted on the surface of land in connection with an underground coal mine. Section 510(b)(3) of SMCRA190 applies to all applications for permits or permit revisions. This provision has never contained an exception for impacts from underground mining operations or for any other type of surface coal mining operations for which a permit is required. 189 30 190 30 E:\FR\FM\27JYP2.SGM U.S.C. 1307 and 1309a.

However, this provision does not justify allowing underground mining operations or subsidence resulting from underground mining operations to dewater or degrade a stream to the extent of precluding an existing, reasonably foreseeable, or designated use of that stream. Doing so would hold underground mines to a lesser standard of environmental protection than surface mines. Nothing in the environmental protection purposes of SMCRA, as set forth in paragraphs (a), (c), (d), and (f) of section 102 of the Act,192 suggests or supports the adoption of a lesser standard for underground mines. We are aware of concerns that including impacts from subsidence in the definition could effectively prohibit use of the longwall mining method or other high-extraction methods of underground mining to recover a substantial proportion of coal reserves. However, application of this definition to the area overlying proposed underground workings and the area within a reasonable angle of draw from the perimeter of those workings would not prohibit all mining operations that would result in subsidence of streams. It would only prohibit mining operations that would result in dewatering of a stream to the extent that the stream would no longer be able to support existing or reasonably foreseeable uses or designated uses of the stream under the Clean Water Act and for which there are no viable measures to prevent this impact. Our draft regulatory impact analysis found that the proposed rule, including this definition, would not strand or sterilize any reserves; i.e., the proposed rule would not make any coal reserves that are technically and economically feasible to mine under baseline conditions unavailable for extraction. Underground mine operators cannot avoid application of section 510(b)(3) of SMCRA193 by drawing the permit boundaries for the mine to include undisturbed areas that may be affected by subsidence. In revising the definition of ‘‘permit area’’ in 1983, we specifically rejected a suggestion that the definition should include all areas overlying underground workings. Instead, we 191 30 U.S.C. 1266(a) and (d).

In other words, state regulatory authorities would have to ensure that the prohibition would apply to all lands overlying the underground mine workings and to all lands within a reasonable angle of draw 195 from the perimeter of those workings, if those lands are not otherwise disturbed by surface operations or facilities associated with the underground mine. redesignation of existing § 784.20 as § 784.30. We propose no other substantive revisions to this definition— only a plain language revision to the last sentence. Parameters of Concern We propose to add a definition of this term because we use this term extensively in our proposed rule. Under the proposed definition, parameters of concern would consist of those chemical or physical characteristics or properties of surface water or groundwater that could be altered by mining activities in a manner that would adversely impact the quality of surface water or groundwater or the biological condition of a stream. Perennial Stream We propose to redefine ‘‘perennial stream’’ in a manner that is substantively identical to the manner in which the U.S. Army Corps of Engineers defines that term in Part F of the 2012 reissuance of the nationwide permits under section 404 of the Clean Water Act. See 77 FR 10184, 10288 (Feb. 21, 2012).

Our existing definition has two principal differences with the Corps’ definition that we propose to adopt. First, our existing definition of a perennial stream would not consider a stream with a base flow resulting from the melting of a snowpack to be a perennial stream because the snowpack does not lie below the local water table and because snowmelt is not considered groundwater. However, the preamble to the definition of ‘‘ephemeral stream’’ that the Corps adopted as part of the 2012 reissuance of the nationwide permits under section 404 of the Clean Water Act states that snowmelt contributes to the flow of intermittent and perennial streams, especially in areas with deep snow packs, and that melting snow should not be considered a precipitation event because the development of a snowpack occurs over the course of a winter season. See 77 FR 10184, 10262 (Feb. 21, 2012). In essence, the preamble discussion would allow a stream originating from a melting snowpack to be considered a perennial stream even though the definition of ‘‘perennial stream’’ requires groundwater as the source of base flow. We invite comment on whether we should revise our proposed definition of ‘‘perennial stream’’ to include language consistent with the discussion of snowmelt in the preamble to the Corps’ definition of ‘‘ephemeral stream.’’ Second, the Corps’ definition of ‘‘perennial stream’’ refers to continuous flow year-round ‘‘during a typical year.’’ Our existing definition refers to continuous flow during all of the calendar year. The Corps’ definition— and hence our proposed definition— reflect the fact that perennial streams or segments of those streams may cease flowing during periods of sustained below-normal precipitation. Our proposed adoption of the Corps’ definition would have the effect of clarifying that those stoppages do not result in reclassification of the stream as intermittent. Reclamation The existing definition of reclamation in 30 CFR 701.5 provides that this term ‘‘means those actions taken to restore mined land as required by this chapter to a postmining land use approved by the regulatory authority.’’ This VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 definition is too narrow and does not fully implement SMCRA. First, the existing definition applies only to the mined area, not to the entire disturbed area. Section 102(e) of SMCRA 199 states that one of the purposes of SMCRA is to ‘‘assure that adequate procedures are undertaken to reclaim surface areas as contemporaneously as possible with the surface coal mining operations.’’ Among other things, the definition of ‘‘surface coal mining operations’’ in section 701(28) of SMCRA 200 includes all activities conducted on the surface of lands in connection with a surface coal mine. Those activities are not limited to mined areas. In addition, paragraph (B) of the definition includes ‘‘the areas upon which such activities occur or where such activities disturb the natural land surface.’’ Therefore, we propose to apply the definition to the entire disturbed area, rather than limiting it to the mined area. Second, the existing definition includes only actions taken to restore land to an approved postmining land use, not to all actions taken to restore land and water to the conditions required by the Act and regulatory program. Third, the existing definition implies that the land must be restored to an actual postmining land use when, in fact, section 515(b)(2) of SMCRA201 requires only that the land be restored to a condition in which it is capable of supporting the uses it was capable of supporting prior to any mining or, subject to certain restrictions, higher or better uses. The proposed definition corrects these deficiencies. Our proposed rule would define reclamation as meaning those actions taken to restore the mined land and associated disturbed areas to a condition in which the site is (1) capable of supporting the uses it was capable of supporting prior to any mining or any higher or better uses approved by the regulatory authority, and (2) meets all other requirements of the permit and regulatory program that pertain to restoration of the site. In addition, our proposed definition specifically details what reclamation means for sites with discharges that require treatment. For those sites, we propose to revise the definition to specify that the term also includes those actions taken or that must be taken to eliminate, remediate or treat those discharges, including both discharges from the mined area and all other discharges that are hydrologically PO 00000 199 30 U.S.C. 1202(e).

However, nothing in this proposed definition should be construed as meaning that the regulatory authority may approve a permit application for an operation that will cause, or that is likely to cause, a postmining discharge that requires treatment to prevent pollution. Doing so would violate SMCRA as explained in the acid mine drainage policy statement that we issued on March 31, 1997.202 Reclamation Plan We propose to add this definition to clarify which provisions of our permit application requirements are considered part of the reclamation plan. Section 701(21) of SMCRA 203 defines ‘‘reclamation plan’’ as ‘‘a plan submitted by an applicant for a permit under a State program or Federal program which sets forth a plan for reclamation of the proposed surface coal mining operations pursuant to section 508 [of SMCRA.]’’ In this proposed rule, we propose to adopt a streamlined version of the statutory definition that complies with plain language principles, eliminates the unnecessary reference to state or federal programs, and contains adaptations needed to reflect the structure and organization of the regulations that correspond to the reclamation plan requirements of SMCRA. Specifically, the proposed rule would replace the reference to section 508 of SMCRA 204 with references to 30 CFR parts 780, 784, and 785. Part 780 contains the rules that implement section 508 of SMCRA.205 Part 784 is the underground mining counterpart of part 780. Part 785 contains permit application requirements, including reclamation plan requirements, that apply to special categories of mining. Renewable Resource Lands We propose to revise this definition to clarify that it includes recharge areas for surface waters, not just recharge areas for underground waters. We find no legal or technical reason to exclude recharge areas for lakes, ponds, and wetlands from classification as renewable resource lands.

Specifically, it provides that lands are eligible for designation if surface coal mining operations would ‘‘affect renewable resource lands in which such operations could result in a substantial loss or reduction of longrange productivity of water supply . . .’’ This statutory provision further provides that those lands ‘‘include aquifers and aquifer recharge areas,’’ but it does not limit the scope of that provision to those areas. Many towns and cities depend upon surface-water reservoirs for their water supply, which means that paragraph (a)(3)(C) would include the watersheds of those reservoirs. Surface disturbances like mining that involve removal of vegetation can significantly impact both the quantity and quality of water available from those watersheds. Replacement of Water Supply We propose to revise this definition by moving existing paragraphs (a) and (b), which describe how the water supply replacement obligation may be satisfied, to the performance standards at 30 CFR 816.40 and 817.40. Existing paragraphs (a) and (b) of the definition are more appropriately categorized as performance standards, which means that they should be codified as part of the performance standards in subchapter K, not as part of the definition of this term. Temporary Diversion We propose to revise this definition in a manner that avoids using part of the term itself (‘‘diversion’’) as part of the definition. In addition, the existing definition, which includes only diversions of streams and overland flow, could be construed as excluding diversion channels used to convey surface runoff or pit water to a siltation structure or treatment facility. We propose to revise the definition to specifically include those channels. tkelley on DSK3SPTVN1PROD with PROPOSALS2 Waters of the United States To promote consistency with the Clean Water Act, we propose to define this term as having the same meaning as the corresponding definition in 40 CFR 230.3(s), which is part of the Section 404(b)(1) Guidelines under the Clean Water Act C. Part 773: Requirements for Permits and Permit Processing 1. Section 773.5: How must the regulatory authority coordinate the permitting process with requirements under other laws? Section 773.5 specifies that each regulatory program must provide for the coordination of review and issuance of SMCRA permits with applicable provisions of various federal laws. It implements, in part, section 503(a)(6) of SMCRA,207 which requires that each state regulatory program establish ‘‘a process for coordinating the review and issuance of permits for surface coal mining and reclamation operations with any other Federal or State permit process applicable to the proposed operations.’’ We propose to add the Clean Water Act, 33 U.S.C. 1251 et seq., to the list of laws for which coordination is required under both state and federal regulatory programs. Almost all surface coal mining operations require Clean Water Act permits and both SMCRA and the Clean Water Act are concerned with protection of water quality, so it makes sense to coordinate the SMCRA and Clean Water Act permitting processes. Coordination of the SMCRA and Clean Water Act permitting processes also would assist in reducing or eliminating potential conflicts between SMCRA and Clean Water Act permits. That outcome would be consistent with section 702(a) of SMCRA,208 which provides that ‘‘[n]othing in this Act shall be construed as superseding, amending, modifying, or repealing’’ the Clean Water Act, any rule or regulation adopted under the Clean Water Act, or any state laws enacted pursuant to the Clean Water Act. In addition, we propose to add the National Environmental Policy Act of 1969 (NEPA), 42 U.S.C. 4371 et seq., to the list of laws for which a coordination process is required under federal regulatory programs. There is no need or basis to apply this coordination requirement to state regulatory programs approved under SMCRA because the Departmental Manual excludes permit applications under state SMCRA regulatory programs from NEPA compliance. See 516 DM 13.3. Finally, we propose to clarify that only federal regulatory programs must establish a process for coordination with the National Historic Preservation Act of 1966 (NHPA), 54 U.S.C. 300101 et seq. This change is consistent with National Mining Association v. John M. Fowler, 324 F.3d 752 (D.C. Cir. 2003), in which 207 30 206 30 U.S.C. 1272(a)(3)(C).

Frm 00044 Fmt 4701 the court held that projects licensed or permitted by state and local agencies pursuant to a delegation or approval by a federal agency are not federally funded or federally licensed undertakings for purposes of section 106 of the NHPA. 2. Section 773.7: How and when will the regulatory authority review and make a decision on a permit application? We propose to restructure 30 CFR 773.7(a) to improve clarity and eliminate a grammatical error in the existing language. There are no substantive revisions to this paragraph. We also propose to add 30 CFR 773.7(b)(2), which would list the factors that the regulatory authority must consider in determining what constitutes a reasonable time for notifying a permit applicant whether the application has been approved or disapproved, in whole or in part. The factors in proposed paragraphs (b))(2)(i) through (iv) reflect the factors listed in section 514(b) of SMCRA.209 Proposed paragraph (b)(2)(v) would require consideration of the time required to complete the interagency permitting coordination process under 30 CFR 773.5. Finally, we propose to redesignate existing 30 CFR 773.7(b) as 30 CFR 773.7(c) and revise that paragraph to specifically state that an applicant for the transfer, assignment, or sale of permit rights has the burden of proof for establishing that the application is in compliance with all regulatory program requirements. We propose to make this change because the transfer, assignment, or sale of permit rights is a type of permit revision, which means that an application of that nature is subject to section 510(a) of SMCRA.210 In relevant part, that paragraph of the Act states that the applicant for a permit or permit revision has the burden of establishing that the application is in compliance with all requirements of the applicable regulatory program. 3. Section 773.15: What findings must the regulatory authority make before approving a permit application? Most of the changes that we propose to make to this section result from either the application of plain language principles or an effort to clarify the meaning and scope of the findings that the regulatory authority must make before approving a permit application. Proposed paragraph (c)(2) would clarify that the finding that the proposed 209 30 210 30 Sfmt 4702 E:\FR\FM\27JYP2.SGM U.S.C. 1264(b). U.S.C. 1260(a). 27JYP2 44479 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules tkelley on DSK3SPTVN1PROD with PROPOSALS2 permit area is not within an area designated as unsuitable for surface coal mining operations under 30 CFR parts 762 and 764 or 769 applies only to lands that are designated as unsuitable for the type of surface coal mining operations that the permit applicant proposed to conduct. For example, lands may be designated as unsuitable only for surface mining, in which case the regulatory authority may approve a permit for an underground mine. Similarly, proposed paragraph (c)(3) would clarify that the finding that the proposed permit area is not within an area subject to the prohibitions of 30 CFR 761.11 does not apply in situations in which one or more of the exceptions (valid existing rights, the existing operation exemption, landowner consent, joint approval, etc.) to those prohibitions applies. We propose to revise the finding in paragraph (e) concerning the assessment of the cumulative hydrologic impacts of mining by adding paragraph (e)(3), which would require that the regulatory authority find that it has inserted into the permit criteria defining material damage to the hydrologic balance outside the permit area on a site-specific basis, expressed in numerical terms for each parameter of concern, as required by § 780.21(b) or § 784.21(b). Our proposed revision is intended to ensure that permit-specific criteria are both established and readily available to the permittee, inspectors, and permit reviewers. Existing paragraph (j) provides that, before approving a permit application, the regulatory authority must find that the proposed operation is not likely to either jeopardize the continued existence of threatened or endangered species or result in destruction or adverse modification of critical habitat, as determined under the Endangered Species Act of 1973, 16 U.S.C. 1531 et seq. In response to discussions with the U.S. Fish and Wildlife Service concerning compliance with the Endangered Species Act, we propose to modify paragraph (j) to extend the finding to include species that the Secretary has proposed for listing as threatened or endangered.211 The proposed change is consistent with section 7(a)(4) of the Endangered Species Act, which provides that 211 We will revise this provision and other proposed rules concerning protection of threatened and endangered species to include the National Marine Fisheries Service (NMFS), which is responsible for administration and enforcement of the Endangered Species Act with respect to anadromous and marine species, if we determine that this rulemaking may affect species under NMFS jurisdiction. VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 ‘‘[e]ach Federal agency shall confer with the Secretary on any agency action which is likely to jeopardize the continued existence of any species proposed to be listed under section 4 or result in the destruction or adverse modification of critical habitat proposed to be designated for such species.’’ It also would assist in implementing the fish and wildlife protection provisions of sections 515(b)(24) and 516(b)(11) of SMCRA. The conferencing requirement of section 7(a)(4) of the Endangered Species Act is not the same as the consultation requirement for threatened and endangered species under section 7(a)(2) of the Endangered Species Act. Also, the U.S. Fish and Wildlife Service is responsible for determining allowable take of species listed as threatened or endangered. We propose to remove existing paragraph (m), which applies to permits to be issued under 30 CFR 785.25 (permits containing lands eligible for remining). This finding is not needed because it merely repeats requirements already stated in 30 CFR 785.25. In addition, paragraph (m) is duplicative of paragraph (h), which requires a finding that the applicant has satisfied all applicable requirements of 30 CFR part 785. Removal of existing paragraph (m) would result in the redesignation of existing paragraph (n) as paragraph (m). In addition, we propose to add a new paragraph (n), which would require that the regulatory authority find that the applicant has demonstrated that the operation has been designed to prevent the formation of discharges that would require long-term treatment after mining has been completed. The regulatory authority also would be required to find that the applicant has demonstrated that there is no credible evidence that the design of the operation will not work as intended to prevent the formation of discharges of that nature. Avoiding creation of discharges that require long-term treatment benefits both the permittee (because the permittee would bear the cost of treating the discharge) and the public (because there is no risk of environmental damage or use of tax receipts to pay for treatment if the permittee defaults). Adoption of proposed paragraph (n) would incorporate into regulation one of the provisions of the policy entitled ‘‘Hydrologic Balance Protection: Policy Goals and Objectives on Correcting, Preventing, and Controlling Acid/Toxic Mine Drainage’’ 212 that we issued on March 31, 1997. In that policy, we 212 See www.osmre.gov/lrg/docs/ amdpolicy033197.pdf (last accessed August 5, 2014). PO 00000 Frm 00045 Fmt 4701 Sfmt 4702 explain that approval of a permit that would result in the creation of a discharge requiring long-term treatment would be inconsistent with SMCRA: ‘‘In no case should a permit be approved if the determination of probable hydrologic consequences or other reliable hydrologic analysis predicts the formation of a postmining pollutional discharge that would require continuing long-term treatment without a defined endpoint.’’ 213 The regulatory authority may rely upon data from similar completed mining operations under conditions that are representative of those found at the site of the proposed operation as credible evidence for this demonstration and finding. We explained our authority for this provision when we issued our policy document: Several commenters expressed concern that OSM exceeded its statutory authority by focusing on section 510(b)(3) of SMCRA, which provides that no permit application may be approved unless the regulatory authority finds that the operation has been designed to prevent material damage to the hydrologic balance outside the permit area, and interpreting that section as requiring the prevention of AMD [acid mine drainage] formation. The commenters noted that sections 515(b)(10) and 516(b)(9) of SMCRA refer to minimization (rather than prevention) of hydrologic disturbances and avoidance (rather than the prevention) of AMD, with the prevention of AMD formation being only one of the three avoidance mechanisms listed in these sections. Response: The minimization and avoidance provisions of sections 515(b)(10) and 516(b)(9) of SMCRA do not negate the material damage prevention requirement of section 510(b)(3). Furthermore, the Act specifies that the provisions cited by the commenters apply only during mining and reclamation. OSM interprets this limitation as meaning that conducting operations in a manner likely to result in AMD production is acceptable only when AMD formation is expected to be a temporary phenomenon. In other words, discharge treatment is an appropriate means of avoiding AMD and minimizing damage to the hydrologic balance only when the need for treatment has a defined endpoint. * * * * * The approach adopted in the policy statement is fully consistent with the Rith Energy decision in which the IBLA [Interior Board of Land Appeals] upheld OSM’s refusal to approve a mining plan that sought to minimize, rather than avoid, AMD. In that case, the IBLA agreed with OSM that ‘‘the statute, as properly read, requires the agency to minimize disturbance to the prevailing hydrologic balance by avoiding acid or toxic mine drainage. Minimizing the contact of water and toxic-producing deposits, as argued by petitioner [Rith Energy], is not the standard.’’ 111 IBLA 249. The policy 213 Id., E:\FR\FM\27JYP2.SGM p. 5. 27JYP2 44480 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules statement accords with Rith Energy because it provides that ‘‘[p]ermits may only be approved where the operation is designed to ensure that off-site material damage to the hydrologic balance will be prevented.’’ (Emphasis added.) Permittees may not plan in advance to allow AMD to occur and then simply mitigate the effects of the AMD.214 Finally, we propose to add a new required finding in paragraph (o) in response to discussions with the U.S. Fish and Wildlife Service concerning compliance with the Endangered Species Act. This finding would specify that, to the extent possible using the best technology currently available, the proposed operation has been designed to minimize disturbances and adverse impacts on fish, wildlife, and related environmental values, as identified in § 779.20 or § 783.20, and to enhance those resources where practicable, as required under § 780.16 and § 784.16. The proposed language is similar to sections 515(b)(24) and 516(b)(11) of SMCRA 215 and is intended to reinforce those statutory provisions. tkelley on DSK3SPTVN1PROD with PROPOSALS2 4. Section 773.17: What conditions must the regulatory authority place on each permit issued? We propose to revise paragraph (c) of this section to require that the permittee comply with all applicable requirements of the Act rather than all applicable performance standards of the Act. We propose to make this change because the condition also requires compliance with the requirements of the regulatory program, which means that the applicable performance standards would be in the program, not the Act. We propose to revise paragraph (e) of this section to require that the permittee notify the regulatory authority and other appropriate state and federal regulatory agencies of any adverse impact to the environment or public health or safety as a result of a noncompliance with any term or condition of the permit. Notification would allow those agencies to take any necessary action to minimize the impacts of the noncompliance on the environment or public health or safety, consistent with the purpose stated in section 102(a) of SMCRA.216 We propose to add a new permit condition in paragraph (h) of this section to require that the permittee obtain all necessary authorizations, certifications, and permits in accordance with Clean Water Act requirements before conducting any activities that require approval or authorization under the Clean Water Act. The new condition would be consistent with section 702(a) of SMCRA,217 which provides that ‘‘[n]othing in this Act shall be construed as superseding, amending, modifying, or repealing’’ the Clean Water Act,218 or any rule or regulation adopted under the Clean Water Act, or any state laws enacted pursuant to the Clean Water Act. It also would be consistent with our efforts to enhance coordination between the SMCRA and Clean Water Act regulatory authorities. Permit conditions are directly enforceable under SMCRA. Therefore, the addition of this permit condition would mean that the SMCRA regulatory authority must take enforcement action if the permittee does not obtain all necessary Clean Water Act authorizations, certifications, and permits before beginning any activity under the SMCRA permit that also requires approval, authorization, or certification under the Clean Water Act. D. Part 774: Revision; Renewal; Transfer, Assignment, or Sale of Permit Rights; Post-Permit Issuance Requirements. 1. Section 774.10: When must the regulatory authority review a permit? We propose to revise paragraphs (a)(2) and (a)(3) of this section to establish identical review requirements for permits for mountaintop removal mining operations under 30 CFR 785.14 and for permits that include a variance from approximate original contour restoration requirements under 30 CFR 785.16. This change is appropriate because the statutory review requirements for those types of operations in paragraphs (c)(6) and (e)(6) of section 515 of SMCRA 219 are substantively identical. Furthermore, these reviews are one-time events, not recurring requirements like midterm permit reviews. In concert with this change, we propose to move the midterm review requirements for permits with a variance for a delay in contemporaneous reclamation requirements because of combined surface and underground mining from paragraph (a)(2) to a new paragraph (a)(4). Creation of the new single-topic paragraph also is in keeping with plain language principles. 2. Section 774.15: How may I renew a permit? We propose to revise paragraph (b)(2) of this section by adding paragraph (b)(2)(vii), which would require that each application for permit renewal 214 Id. 217 30 215 30 at 12 and 14.

We also propose to add paragraph (b)(2)(viii), which would require that the renewal application include either an update of the PHC determination or documentation that the findings in the existing PHC determination are still valid. Similarly, we propose to revise paragraph (c)(1) of this section by adding paragraph (c)(1)(viii), which would authorize the regulatory authority to withhold approval of a permit renewal application if monitoring results or the updated PHC determination indicate that the finding that the regulatory authority made under 30 CFR 773.15(e) that the operation is designed to prevent material damage to the hydrologic balance outside the permit area is no longer accurate. These revisions would assist the regulatory authority in ensuring that the operation continues to be designed and conducted to prevent material damage to the hydrologic balance outside the permit area. A narrow reading of section 510(b)(3) of SMCRA 220 and 30 CFR 773.15(e) might hold that the finding concerning material damage to the hydrologic balance outside the permit area is required only for the approval of an application for a permit or permit revision. However, we interpret section 510(b)(3) of SMCRA more broadly. Addition of a requirement for an equivalent finding as a prerequisite for the approval of permit renewal applications is consistent with the intent and purpose of section 510(b)(3) of the Act.221 Proposed paragraph (b)(2)(v) is substantively identical to existing paragraph (b)(2)(iii), with the exception that we propose to remove the provision requiring that the application for a permit renewal include any additional bond requested by the regulatory authority. This provision is both unnecessary and out of sequence because, at the time that the permittee submits the application for renewal, the amount of additional bond needed, if any, would not yet be known. The regulatory authority determines the amount of additional bond required after completing a technical review of the renewal application.

This paragraph provides sufficient protection against renewal of a permit that lacks the necessary bond coverage. We propose to revise paragraph (c)(1)(ii) to specify that the regulatory authority will apply the permit eligibility standards in 30 CFR 773.12 through 773.14 in making this determination. In other words, applicants for permit renewal may avail themselves of the provisionally-issued permit procedures of 30 CFR 773.14 and the exception in 30 CFR 773.13 for unanticipated events or conditions at remining sites. Extending the exception for unanticipated events or conditions at remining sites to permit renewals is consistent with the intent of Congress in enacting section 510(e) of SMCRA.222 In addition, as a matter of equitable treatment, a permittee with a violation who is seeking renewal of a permit should have the same opportunity to obtain a provisionally-renewed permit as a person with a violation who is seeking to obtain a new permit has to obtain a provisionally-issued permit. Under 30 CFR 773.14, the regulatory authority may provisionally issue a permit if (1) the applicant certifies that each outstanding violation is being abated to the satisfaction of the agency with jurisdiction over the violation and the regulatory authority has no evidence to the contrary, (2) the applicant and operations owned or controlled by the applicant are in compliance with any abatement plan approved by the agency with jurisdiction over the violation, (3) the applicant is pursuing a good faith challenge to the pertinent ownership or control listing and there is no initial judicial decision in force affirming the listing, or (4) the violation is the subject of a good faith administrative or judicial appeal contesting the validity of the violation and there is no initial judicial decision in force affirming the violation. Our proposed revisions to 30 CFR 774.15(c)(1)(ii) would apply the same principles and criteria to the permit renewal process. In addition, the provisions of 30 CFR 773.14(c), which specify the actions that the regulatory authority must take to suspend or revoke the permit if the permittee ceases to be eligible for a provisionally-issued permit, would apply. We also propose assorted other nonsubstantive changes to 30 CFR 774.15 to improve compliance with plain language principles. 222 30 E. Part 777: General Content Requirements for Permit Applications 1. Section 777.11: What are the format and content requirements for permit applications? We propose to revise paragraph (a)(3) of this section to require that permit applications be filed in an electronic format prescribed by the regulatory authority, unless the regulatory authority grants an exception to this requirement for good cause. We propose this change to facilitate public participation and interagency coordination in the permitting process because it is much more efficient and convenient to review and exchange information online or by email than it is to review hard copies, which are time-consuming to produce and which may involve considerable travel to other offices to review documents that cannot be copied. Electronic filing also would assist in the coordination of regulatory and inspection activities required by section 713 of SMCRA.223 Furthermore, use of an electronic format for the permitting process can improve efficiency by enabling correction letters and applicant responses to occur in real time with less expense to the regulatory authority and the applicant. Finally, electronic filing promotes attainment of the goals of the Paperwork Reduction Act. 2. Section 777.13: What requirements apply to the collection, analysis, and reporting of technical data and to the use of models? We propose to consolidate existing paragraphs (a) and (b) into proposed paragraph (a) because both paragraphs pertain to technical data and analyses. Existing paragraph (a) would be recodified as paragraph (a)(1) and existing paragraph (b) would be recodified as paragraph (a)(2). Proposed paragraph (a)(1) would add a requirement for submission of metadata, which consists of data describing the contents and context of data files. The availability of metadata greatly increases the usefulness of the original data by providing information about how, where, when, and by whom the data were collected and analyzed. It enables reviewers to evaluate the validity of both the data itself and comparisons with data collected at other times and other places by other persons. Existing paragraph (a) already required submission of much of this information, i.e., the names of persons or organizations that collected and analyzed the data, the dates that the U.S.C. 1260(e). VerDate Sep<11>2014 19:15 Jul 24, 2015 223 30 Jkt 235001 PO 00000 U.S.C. 1303. Frm 00047 Fmt 4701 Sfmt 4702 44481 data were collected and analyzed, and descriptions of the methodology used to collect and analyze the data. We also propose to revise the rule to add requirements for submission of the field sampling sheets prepared for water samples collected from wells (the sheets would identify the presence of any well screens as well as the depth at which the sample was taken). For all samples that require laboratory analysis, the proposed rule would require information pertaining to the quality assurance and quality control procedures used by the laboratory that analyzed the sample. For electronic data, the proposed rule would require identification of any transformations that the data underwent. The proposed rule would not limit metadata to the specific items listed in proposed paragraph (a)(1). Although not specified in the proposed rule, metadata should be generated in a format commonly used by the scientific community. Proposed paragraph (b) would require that all sampling and analyses of groundwater and surface water performed to meet the permitting requirements of subchapter G of our regulations be conducted according to the methodology in 40 CFR parts 136 and 434. Proposed paragraph corresponds to the provisions concerning water-quality sampling and analysis methodologies in existing 30 CFR 780.21(a) and 784.14(a). Moving this provision to 30 CFR 777.13 would consolidate the requirements concerning sampling and analysis methodologies for groundwater and surface water in one location and expand their applicability to all pertinent data and analyses required for permit applications under subchapter G, which should promote better data collection and analysis procedures and, hence, improved permitting decisions. We propose to eliminate the incorporation by reference of the 15th edition of the ‘‘Standard Methods for the Examination of Water and Wastewater’’ in existing 30 CFR 780.21(a) and 784.14(a). That document is now obsolete because the current edition is the 22nd edition, which was published in 2012. However, rather than incorporating the current edition of the ‘‘Standard Methods for the Examination of Water and Wastewater,’’ we propose to remove the existing incorporation by reference of the 15th edition of that document while retaining the provision in the existing rule that allows use of the sampling and analysis methodologies in 40 CFR parts 136 and 434. This proposed change would ensure that sampling and analysis methodologies under SMCRA are E:\FR\FM\27JYP2.SGM 27JYP2 44482 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules tkelley on DSK3SPTVN1PROD with PROPOSALS2 consistent with those approved by EPA for use for Clean Water Act purposes. We invite comment on whether there are any unique SMCRA-related requirements that would necessitate incorporating the current edition of the ‘‘Standard Methods for the Examination of Water and Wastewater’’ into our rule. In other words, would the collection and analysis of the baseline and monitoring data that we propose to require under this rule involve the use of sampling and analysis methodologies that 40 CFR parts 136 and 434 do not include? Proposed paragraph (c) would require that all geological sampling and analyses performed to meet the permitting requirements of subchapter G of our regulations be conducted using a scientifically-valid methodology. This new provision should promote better geologic data collection and analysis procedures and, hence, improved permitting decisions. Scientificallyvalid methodologies include, but are not limited to, those set forth in the Engineering Geology Field Manual, Second Edition (1998), developed by the Bureau of Reclamation within the U.S. Department of the Interior. We propose to move the provisions concerning the use of models found in existing 30 CFR 780.21(d) and 784.14(d) to 30 CFR 777.13(d) to consolidate requirements concerning the use of models in the latter paragraph. If adopted as final, proposed paragraph (d) would apply to all permit application requirements. The existing provisions in 30 CFR 780.21(d) and 784.14(d) apply only to hydrologic data, but we find no scientific reason for limiting the use of modeling in this manner. We also propose to modify the existing provisions by adding paragraph (d)(2), which would require that all models be calibrated using actual site-specific data and that they be validated for the region and ecosystem in which they will be used. The additional requirements are intended to improve the accuracy and validity of any models used. Finally, we propose to add a new paragraph (d)(3) clarifying that the regulatory authority has the discretionary authority to prohibit the use of models and to require the submission of additional actual, site-specific data. 3. Section 777.15: What information must my application include to be administratively complete? We propose to revise this section to use terminology consistent with the revisions to the permitting regulations published on September 28, 1983 (48 FR 44344), which removed the term ‘‘complete application’’ and replaced it VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 with the terms ‘‘administratively complete application’’ and ‘‘complete and accurate application.’’ F. Part 779: Surface Mining Permit Applications—Minimum Requirements for Information on Environmental Resources and Conditions 1. Section 779.1: What does this part do? Existing 30 CFR 779.1 states that part 779 establishes the minimum requirements for the Secretary’s approval of regulatory program provisions for the environmental resources contents of permit applications for surface mining activities. However, the content requirements and standards for approval of state regulatory programs are located in 30 CFR parts 730 through 732. Therefore, we propose to revise 30 CFR 779.1 to specify that part 779 sets forth permit application requirements relating to environmental resources and conditions. 2. Section 779.2: What is the objective of this part? We propose to revise this section to reflect plain language principles and to clarify that the objective of part 779 is to ensure that the permit applicant provides the regulatory authority with a complete and accurate description of both the environmental resources that may be impacted or affected by proposed surface mining activities and the environmental conditions that exist within the proposed permit and adjacent areas. The existing language does not mention environmental conditions, such as the information on climate required by 30 CFR 779.18. 3. Why are we proposing to remove existing 30 CFR 779.11 and 779.12? We propose to remove 30 CFR 779.11, which requires a description of the existing premining environmental resources within the proposed permit and adjacent areas, because the requirements for this description are set out in detail in other sections of part 779. Therefore, existing 30 CFR 779.11 is redundant and unnecessary. We propose to remove existing 30 CFR 779.12(a) because the anticipated mining schedule that it requires is duplicative of proposed 30 CFR 779.24(a)(3). We propose to move the cultural resource requirements of existing 30 CFR 779.12(b) to a new 30 CFR 779.17 devoted to that topic. PO 00000 Frm 00048 Fmt 4701 Sfmt 4702 4. Section 779.19: What information on vegetation must I include in my permit application? We propose to revise existing 30 CFR 779.19 by adding more specificity and making submission of vegetation information mandatory rather than discretionary as under the existing rules. The changes that we propose are needed to ensure that native plant communities are restored on reclaimed areas as required by section 515(b)(19) of SMCRA.224 Further, these changes are intended to implement, in part, section 515(b)(24) of SMCRA,225 which requires that, ‘‘to the extent possible using the best technology currently available,’’ surface coal mining and reclamation operations be conducted in a manner that will ‘‘minimize disturbances and adverse impacts on fish, wildlife, and related environmental values, and achieve enhancement of such resources where practicable.’’ Restoration or establishment of native plant communities is the most effective way of restoring or enhancing wildlife habitat. The Virginia Department of Conservation and Natural Resources describes the benefits of native plants as follows: The benefit of growing plants within the region they evolved is they are more likely to thrive under the local conditions while being less likely to invade new habitats. Native plants are well adapted to local environmental conditions, maintain or improve soil fertility, reduce erosion, and often require less fertilizer and pesticides than many alien plants. These characteristics save time and money and reduce the amount of harmful run-off threatening the aquatic resources of our streams, rivers, and estuaries. In addition, functionally healthy and established natural communities are better able to resist invasions by alien plant species. So the use of native plants can help prevent the spread of alien species already present in a region and help avert future introductions. *** Native plants provide familiar sources of food and shelter for wildlife. As natural habitats are replaced by urban and suburban development, the use of native plants in landscaping can provide essential shelter for displaced wildlife. Land managers can use native plants to maintain and restore wildlife habitat. Native wildlife species comprise a majority of the game and non-game animals we manage habitat for, and they evolved with native plant species. Although alien species are often promoted for their value as wildlife food plants, there is no evidence that alien plant materials are superior to native plants. For instance, on land managed for upland game animals, native warm season grasses (big and little bluestem, switch grass, Indian grass, coastal panic grass, gama grass), and other native forbs (butterfly weed, ironweed, 224 30 225 30 E:\FR\FM\27JYP2.SGM U.S.C. 1265(b)(19). U.S.C. 1265(b)(24). 27JYP2 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules Joe Pye weed) offer good sources of nutrition without the ecological threats associated with nonnative forage plants. Dramatic increases in nesting success of both game birds and songbirds have been observed in fields planted with native grasses, which also offer superior winter cover. In addition, warm season grasses provide productive and palatable livestock forage. *** On a broader ecological scale, planting native species contributes to the overall health of natural communities. Disturbances of intact ecosystems that open and fragment habitat, such as land clearing activities, increase the potential of invasion by alien species. Native plants provide important alternatives to alien species for conservation and restoration projects in these disturbed areas. They can fill many land management needs currently occupied by nonnative species, and often with lower costs and maintenance requirements. Once established in an appropriate area, most native plant species are hardy and do not require watering, fertilizers, or pesticides.226 A U.S. Fish and Wildlife Service publication describes the benefits of native plants as follows: Native plants naturally occur in the region in which they evolved. While non-native plants might provide some of the above benefits, native plants have many additional advantages. Because native plants are adapted to local soils and climate conditions, they generally require less watering and fertilizing than non-natives. Natives are often more resistant to insects and disease as well, and so are less likely to need pesticides. Wildlife evolved with plants; therefore, they use native plant communities for food, cover and rearing young. Using native plants helps preserve the balance and beauty of natural ecosystems.227 tkelley on DSK3SPTVN1PROD with PROPOSALS2 Notwithstanding the advantages of native plant communities, many regraded and revegetated areas do not contain a diverse, effective, permanent vegetative cover of the same seasonal variety native to the area as required by section 515(b)(19) of SMCRA.228 Instead, areas that were previously forested were backfilled, regraded, and revegetated in a manner that makes the land incapable of achieving its premining forested status. Those lands are now heavily compacted grasslands with scrub trees. Neither grassland nor the trees are representative of the native premining vegetation. A 2007 study estimates that Appalachia alone contains between 750,000 and 1.5 million acres of such reclaimed mine 226 https://www.dcr.virginia.gov/natural_heritage/ nativeplants.shtml (last accessed August 27, 2014). 227 Slattery, Britt E., Kathryn Reshetiloff, and Susan M.

Moreover, the proposed rule is consistent with Section 2.(a)(2)(iv) of Executive Order 13112, ‘‘Invasive Species,’’ which requires that ‘‘[e]ach Federal agency whose actions may affect the status of invasive species shall, to the extent practicable and permitted by law, . . . provide for the restoration of native species and habitat conditions in ecosystems that have been invaded.’’ 232 Proposed paragraph (a) would require that the permit application identify, describe, and map existing vegetation and plant communities, as well as those plant communities that would exist under conditions of natural succession. The description and map must be adequate to evaluate whether the vegetation provides important habitat for fish and wildlife and whether the site contains any native plant communities of local or regional significance. Proposed paragraph (b) would require that the applicant adhere to the classifications in the National Vegetation Classification Standard (NVCS) 233 in preparing the description required under proposed paragraph (a). The NVCS is the standard endorsed by the Federal Geographic Data Committee.234 Use of this standard would promote consistent identification of plant communities and development of appropriate revegetation plans to restore those communities following mining. Proposed paragraph (c) would allow the regulatory authority to approve the use of other generally-accepted vegetation classification systems in lieu 229 Zipper, C.E., J.A. Burger, J.M.

Proposed paragraph (d) would require that the application include a discussion of the potential for reestablishing the plant communities described in paragraph (a) after the completion of mining. This discussion would assist the regulatory authority in evaluating the proposed revegetation plan and in determining which plant communities the permittee must reestablish. 5. Section 779.20: What information on fish and wildlife resources must I include in my permit application? The fish and wildlife resource information requirements in existing 30 CFR 780.16(a) identify the baseline fish and wildlife resource information that each permit application must include. Therefore, we propose to move it to part 779, which contains environmental resource information requirements for permit applications. Part 779 is a better fit for a fish and wildlife resource information requirement than part 780, which contains operation and reclamation plan requirements. The fish and wildlife information requirements in existing 30 CFR 780.16(a) and proposed 30 CFR 779.20 are necessary to fully implement the fish and wildlife protection and enhancement requirements of section 515(b)(24) of SMCRA.235 Proposed paragraph (c)(1) is similar to the portion of existing 30 CFR 780.16(a)(2)(i) that pertains to species listed or proposed for listing as threatened or endangered under the Endangered Species Act of 1973, 16 U.S.C. 1531 et seq., and to critical habitat designated under that law. We propose to add a requirement that the site-specific resource information include a description of the effects of future state or private activities that are reasonably certain to occur within the proposed permit and adjacent areas. The requested information will assist the U.S. Fish and Wildlife Service in fulfilling its responsibilities under the coordination process pertaining to threatened or endangered species. Proposed paragraph (c)(2) is substantively identical to the portion of existing 30 CFR 780.16(a)(2)(i) that pertains to species or habitat protected by state statutes similar to the Endangered Species Act. In proposed paragraph (c)(3), which corresponds to existing 30 CFR 780.16(a)(2)(ii), we propose to expand the list of examples of habitat of unusually high value to fish and 235 30 E:\FR\FM\27JYP2.SGM U.S.C. 1265(b)(24). 27JYP2 tkelley on DSK3SPTVN1PROD with PROPOSALS2 44484 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules wildlife to include areas that support populations of endemic species that are vulnerable because of restricted ranges, limited mobility, limited reproductive capacity, or specialized habitat requirements. We propose to delete the reference to important streams in the existing regulation because proposed paragraph (c)(5) would require sitespecific information for all perennial and intermittent streams, not just important streams. Proposed paragraph (c)(4) is substantively identical to existing 30 CFR 780.16(a)(2)(iii), except for the addition of language clarifying that this provision includes species identified as sensitive by a state or federal agency. Proposed paragraph (c)(6) would require submission of site-specific information when native plant communities of local or regional ecological significance are present. Proposed paragraph (d) includes the U.S. Fish and Wildlife Service permit application review provisions found at 30 CFR 780.16(c) in our existing rules. We propose to revise those provisions in response to discussions with the U.S. Fish and Wildlife Service concerning compliance with the Endangered Species Act. We will further revise this provision and other proposed rules concerning protection of threatened and endangered species to include the National Marine Fisheries Service (NMFS), which is responsible for administration and enforcement of the Endangered Species Act with respect to anadromous and marine species, if we determine that this rulemaking may affect species under NMFS jurisdiction. Proposed paragraph (d)(1)(i) would require that the regulatory authority provide the fish and wildlife resource information included in the permit application under proposed paragraph (c) to the applicable regional or field office of the U.S. Fish and Wildlife Service whenever that information includes species listed as threatened or endangered under the Endangered Species Act, critical habitat designated under that law, or species proposed for listing as threatened or endangered under that law. The proposed rule would require that the regulatory authority provide this information to the Service no later than the time that it provides written notice of receipt of an administratively complete permit application to the Service under § 773.6(a)(3)(ii). Under the existing rule, the Service must request this information from the regulatory authority rather than receiving it automatically. Proposed paragraph (d)(1)(ii) is similar to the existing rule in that it VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 allows the Service to request fish and wildlife resource information submitted as part of permit applications even when the information in those applications does not include species listed as threatened or endangered under the Endangered Species Act, critical habitat designated under that law, or species proposed for listing as threatened or endangered under that law. Under both the existing and proposed rules, the regulatory authority must provide that information to the Service within 10 days of receipt of the request. Proposed paragraph (d)(2) specifies how the regulatory authority must handle comments received from the Service and how any disagreements are to be resolved. This proposed paragraph generally parallels the provisions that we and the Service agreed to as a result of a formal section 7(a)(2) Endangered Species Act consultation pertaining to the approval and conduct of surface coal mining and reclamation operations under a SMCRA regulatory program. Specifically, proposed paragraphs (d)(2)(i) through (iii) provide that if the regulatory authority does not agree with a Service recommendation that pertains to fish and wildlife or plants listed as threatened or endangered under the Endangered Species Act or to critical habitat designated under that law, the regulatory authority must explain the rationale for that decision in a comment disposition document and must provide a copy of that document to the pertinent Service field office. The proposed rule also would require that the regulatory authority provide a copy of that document to the appropriate OSMRE field office for informational purposes and to allow the OSMRE field office to monitor resolution of the disagreement. If the Service field office does not concur with the regulatory authority’s decision and the regulatory authority and the Service field office are subsequently unable to conclude an agreement at that level, the proposed rule allows either the regulatory authority or the Service to elevate the issue through the chain of command of the regulatory authority, the Service, and OSMRE for resolution. Proposed paragraph (d)(2)(iv) provides that the regulatory authority may not approve the permit application until all issues are resolved in accordance with this process and the regulatory authority receives written documentation from the Service that all issues have been resolved. Like all provisions in proposed paragraph (d)(2), this provision is intended to ensure the protection of threatened and endangered PO 00000 Frm 00050 Fmt 4701 Sfmt 4702 species in accordance with the Endangered Species Act. Proposed paragraph (e) provides that the regulatory authority may require the prevention of adverse impacts to streams and watersheds in the permit and adjacent areas in order to protect exceptional environmental values. The proposed rule would require that all decisions be based upon scientific principles and analyses. In addition, it would require coordination with state and federal fish and wildlife agencies and agencies responsible for implementing the Clean Water Act before taking action under this paragraph. The protection that this proposed rule would provide through the permitting process would be in addition to any protection that might be available through the process for designating lands as unsuitable for surface coal mining operations under section 522 of SMCRA.236 The proposed rule is consistent with section 102(c) of SMCRA,237 which provides that one of the purposes of the Act is to ‘‘assure that surface mining operations are not conducted where reclamation as required by this Act is not feasible.’’ Section 515(b)(23) of SMCRA,238 requires that surface coal mining and reclamation operations ‘‘meet such other criteria as are necessary to achieve reclamation in accordance with the purposes of this Act, taking into consideration the physical, climatological, and other characteristics of the site.’’ The site-specific nature of our proposed rule is consistent with this provision of the Act. 6. Section 779.21: What information on soils must I include in my permit application? Existing 30 CFR 779.21 requires that each permit applicant submit adequate soil survey information for the proposed permit area. On August 4, 1980, we suspended the existing rules insofar as they apply to lands other than prime farmland.239 The suspension reflects the February 26, 1980, decision of the U.S. District Court for the District of Columbia in litigation concerning the permanent regulatory program rules that we adopted in 1979. In that decision, the court held that section 507(b)(16) of SMCRA 240 is a clear expression of congressional intent to require soil surveys only for prime farmlands identified by a reconnaissance inspection. The court also ruled that the 236 30 U.S.C. 1272. U.S.C. 1202(c). 238 30 U.S.C. 1265(b)(23). 239 45 FR 51548 (Aug. 4, 1980). 240 30 U.S.C. 1257(b)(16). 237 30 E:\FR\FM\27JYP2.SGM 27JYP2 tkelley on DSK3SPTVN1PROD with PROPOSALS2 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules Secretary’s reliance on section 508(a)(3) of SMCRA 241 as justification for the rule was misplaced.242 We propose to lift the suspension of existing 30 CFR 779.21 and replace the provisions of the existing rule with revised rule text that is consistent with the court decision. Proposed paragraph (a) would require that the application include the results of a reconnaissance inspection of the proposed permit area to determine whether or not prime farmland is present, as required by 30 CFR 785.17(b)(1). If that inspection indicates that prime farmland may be present, proposed paragraph (e) would require that the application include the soil survey information required by 30 CFR 785.17(b)(3). Proposed paragraphs (a) and (e) do not contain any new requirements; they merely include and cross-reference existing prime farmland regulations. Proposed paragraph (b) would require a map showing all soil mapping units located within the proposed permit area, if the National Cooperative Soil Survey (NCSS) has completed and published a soil survey for the area. The application also would be required to include either a link to the appropriate soil survey information on the Natural Resources Conservation Service (NRCS) Web site, which is located at https:// websoilsurvey.sc.egov.usda.gov/App/ HomePage.htm (as of August 27, 2014), or the equivalent information in paper form. Proposed paragraph (c) would require a description of soil depths within the proposed permit area. Proposed paragraph (d) would require detailed information on soil quality to satisfy the requirements of proposed 30 CFR 780.12(e)(2)(ii) if the permit applicant seeks approval for the use of soil substitutes or supplements under 30 CFR 780.12(e). Proposed paragraph (e) is discussed above together with proposed paragraph (a). Proposed paragraph (f) would require that the permit applicant provide any other information that the regulatory authority finds necessary to determine land use capability and to prepare the reclamation plan. The revised version of 30 CFR 779.21 that we are proposing today would be consistent with the decision in PSMRL I, Round I. First, the proposed rule would not require that the applicant conduct an actual soil survey for lands other than prime farmland. Instead, it would require submission of only 241 30 U.S.C. 1258(a)(3). re Permanent Surface Mining Regulation Litig. I, Round I (PSMRL I, Round I), 1980 U.S. Dist.

Law Inst.) 20208. existing soil survey information, which, apart from transferring pertinent information to the permit application maps, can be provided by reference to the appropriate link to the NRCS Web site. The proposed rule would not require that the applicant conduct an actual soil survey if the information is not available from the NRCS. (The NRCS has completed soil surveys for more than 99 percent of the land area within the conterminous states.) Second, the statutory basis for proposed 30 CFR 779.21 is section 508(a)(2) of SMCRA,243 not section 508(a)(3).244 The court held that section 508(a)(3) did not constitute authority for the prior rule. However, section 508(a)(2) provides that— Each reclamation plan submitted as part of a permit application pursuant to any approved State program or a Federal program under the provisions of this Act shall include, in the degree of detail necessary to demonstrate that reclamation required by the State or Federal program can be accomplished, a statement of: * 19:15 Jul 24, 2015 Jkt 235001 * * * All the information that we propose to require in 30 CFR 779.21 consists of soil and foundation characteristics. Section 508(a)(2) of SMCRA 245 requires the applicant to include that information in each permit application, not just in those applications that contain prime farmland. Identification of soil mapping units and submission of available soil survey information about those units, as proposed paragraph (b) would require, is critical to determining the premining capability of the land, as required by section 508(a)(2)(B) of SMCRA,246 and to establishing the soil salvage and replacement requirements needed to ensure that the revegetation requirements of the Act and regulations can be met. Likewise, the premining soil depth, soil quality, and other information that would be required under proposed paragraphs (c), (d), and (f) also is needed for the applicant and the regulatory authority to effectively determine the premining capability of the land and to establish the soil salvage, soil substitute, and soil replacement requirements needed to ensure that the revegetation requirements of the Act and regulations can be met.

Section 779.22: What information on land use and productivity must I include in my permit application? The counterpart in our existing rules to this section is 30 CFR 780.23(a). We propose to delete the second sentence of existing paragraph (a)(1), which provides that the application must include a description of the historical use of the land if the premining use changed within the 5 years preceding the anticipated starting date of the proposed operation. SMCRA does not include a similar provision and this timeframe has sometimes proven difficult to determine with precision. Furthermore, this information has little or no value in the existing permitting process because it is not a criterion or determinant of any permitting decisions under the existing rules. The proposed rule would continue to require that the application include a narrative analysis of the capability of the land before any mining to support a variety of uses, as required by section 508(a)(2)(B) of SMCRA.247 We propose to require a description of all historical uses of the land without a time limitation and without limitation to the single use preceding the permit application, as a component of this narrative because historical uses provide documentation, in part, of premining land use capability. Our proposed revisions are consistent with the legislative history of this provision of SMCRA, which states that: The description is to serve as a benchmark against which the adequacy of reclamation and the degradation resulting from the proposed mining may be measured. It is important that the potential utility which the land had for a variety of uses be the benchmark rather than any single, possibly low value, use which by circumstances may have existed at the time mining began.248 Thus, it is clear that a single-use criterion is not in accordance with sections 508(a) and 515(b)(2) of SMCRA 249 or the legislative history of section 508(a). The postmining land use must be compared with the variety of uses that the land was capable of supporting before any mining, not just a single premining use. We also propose to add paragraph (b)(3), which would require that the permit application include a narrative 243 30 244 30 Frm 00051 Fmt 4701 Sfmt 4702 247 30 U.S.C. 1258(a)(2)(B). Rep.

Section 508(a)(2)(C) of SMCRA 250 lists productivity in terms of the average yield of food, fiber, forage, or wood products, but it is not an exclusive list of productivity measures that can be used to assess premining productivity. The fish and wildlife information required by proposed paragraph (b)(3) would assist the regulatory authority in evaluating the environmental impacts of the proposed operation and in determining what fish and wildlife protection and enhancement measures may be appropriate. Limiting productivity measures to quantifiable commodity indicators such as food, fiber, and wood products would incorrectly ignore the underlying purposes of SMCRA, one of which is to establish a nationwide program to protect society and the environment from the adverse effects of surface coal mining operations.251 Following the same logic, we propose to add paragraph (c), which would allow the regulatory authority to require submission of any additional information that the regulatory authority deems necessary to determine the condition, capability, and productivity of the land within the proposed permit area. This additional information may include data concerning the site’s carbon absorption and storage capability. 8. Section 779.24: What maps, plans, and cross-sections must I submit with my permit application? We propose to consolidate existing 30 CFR 779.24 and 779.25 into 30 CFR 779.24 and add a new paragraph (c) to clarify that the regulatory authority may require that the applicant submit all materials in a digital format that includes all necessary metadata. We invite comment on whether the digital format option should instead be mandatory to facilitate review by both the public and the regulatory authority. Other substantive proposed changes are discussed below. Proposed paragraph (a)(3) would require a description of the size, sequence, and timing of the mining of subareas for which the applicant anticipates seeking additional permits or expansion of an existing permit in the future. The corresponding existing rule at 30 CFR 779.24(c) applies this requirement to areas for which the applicant anticipates seeking additional permits. However, in practice, regulatory authorities do not always 250 30 U.S.C. 1258(a)(2)(C). 251 See 30 U.S.C. 1202(a).

Some state regulatory programs allow expansion by means of permit amendments or revisions. We have approved state program amendments of this nature, provided that the program amendment specifies that the permit amendment or revision application is subject to the same information requirements as a new permit and that the application must be processed and approved in the same manner as a new permit. We have found that amendments containing those provisions are no less stringent than section 510(a)(3) of SMCRA,252 which provides that, except for incidental boundary revisions, any extension of the area covered by a permit must be made by application for a new permit. The proposed language would reflect this reality and ensure that the description would include all subareas for which the applicant anticipates seeking approval to mine in the future, not just those subareas for which the applicant anticipates seeking new permits. Proposed paragraphs (a)(7), (a)(8), (a)(9), (a)(18), (a)(20), and (a)(27) would allow certain information that is not particularly amenable to display on a map to instead be submitted in a table cross-referenced to a map if approved by the regulatory authority. This information would include depth of water, gas and oil wells; ownership of wells and groundwater resources; ownership and descriptions of surfacewater features; and elevations and geographic coordinates of test borings, core samplings, and monitoring stations. In proposed paragraph (a)(11), we propose to add a provision requiring mapping of all public water supplies and wellhead protection zones 253 located within one-half mile of the proposed permit area. This information would be important in preparing the cumulative hydrologic impact assessment required by section 510(b)(3) of SMCRA 254 and may be of value in preparing the PHC determination and hydrologic reclamation plan for the proposed permit. Proposed paragraph (a)(13) would add a requirement for a map showing the location of any discharge, including, but not limited to, a mine-water treatment or pumping facility, into or from an active, inactive, or abandoned underground mine that is hydrologically U.S.C. 1260(b)(3). wellhead protection zone or area is a surface and subsurface land area regulated under the Safe Drinking Water Act (42 U.S.C. 330f-300j) to prevent contamination of a well or well-field supplying a public water system. 254 30 U.S.C. 1260(b)(3).

Our inspectors have found that this information often is time-consuming or difficult to locate in the permit file or to determine from maps included in that file, so a list of features with their geographic coordinates should improve the efficiency with which regulatory authority and OSMRE personnel perform their duties by greatly improving the ability of regulatory authority and OSMRE personnel to field-check those locations using GPS devices. The requirement for geographic coordinates also is intended to ensure that the locations of these features are determined by an actual survey rather than approximated on a topographic map. Proposed paragraph (a)(19) would expand upon the requirement in existing 30 CFR 779.25(a)(6) for the location and extent of subsurface water, if encountered, by adding provisions concerning aquifers that currently are found only in the corresponding requirements for underground mines at existing 30 CFR 783.25(a)(6). Specifically, we propose to require that the application include the areal and vertical distribution of aquifers and a portrayal of seasonal variations in hydraulic head in different aquifers. This information is equally important for proposed surface mining operations because it would be used to establish baseline groundwater conditions and predict the impacts of the proposed mining operation on those aquifers, regardless of whether the proposed operation is a surface mine or an underground mine. Furthermore, section 507(b)(14) of SMCRA,257 which is the primary statutory counterpart to proposed 30 CFR 779.24, expressly requires that the application include the location of aquifers. In addition, 255 30 U.S.C. 1257(b)(11).

In proposed paragraph (a)(21), we propose to add a requirement that the maps, cross-sections, and plans include the commonly used names of the coal seams to be mined, overburden strata, and the stratum immediately below the lowest coal seam to be mined. This information would assist reviewers in predicting the impacts of the proposed operation by facilitating consultation with published reference materials on the coal seams and geological strata in question. In proposed paragraph (a)(27), we propose to add a requirement that the application identify all directional or horizontal drilling for hydrocarbon extraction operations, including those using hydraulic fracturing methods, within or underlying the proposed permit and adjacent areas. Both the applicant and the regulatory authority need this information to determine the probable hydrologic consequences of the proposed operation and to ensure that the operation’s design takes these operations and wells into consideration. G. Part 780: Surface Mining Permit Applications—Minimum Requirements for Reclamation and Operation Plans 1. Section 780.1: What does this part do? Existing 30 CFR 780.1 states that part 780 provides the minimum requirements for the Secretary’s approval of regulatory program provisions for the mining operations and reclamation plan portions of permit applications for surface mining activities, except to the extent that part 785 establishes different requirements. However, the content requirements and standards for approval of state regulatory programs are located in 30 CFR parts 730 through 732. Therefore, we propose to revise 30 CFR 780.1 to specify that part 780 sets forth permit application requirements for reclamation and operation plans for proposed operations. tkelley on DSK3SPTVN1PROD with PROPOSALS2 2. Section 780.2: What is the objective of this part? We propose to revise this section to specifically mention reclamation of the disturbed area to reflect the fact that part 780 includes numerous reclamation requirements. The existing rule only mentions surface mining activities. We recognize that this change is not essential because the definition of ‘‘surface mining activities’’ in 30 CFR VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 700.5 includes reclamation, but adding a mention of reclamation in 30 CFR 780.2 would make this rule clearer to the reader. 3. Section 780.12: What information must the reclamation plan include? Paragraph (a): General Requirements Proposed paragraph (a) is substantively identical to existing 30 CFR 780.18(a) with one exception. The existing rule requires that each permit application contain a reclamation plan showing how the applicant will comply with section 515 of SMCRA,258 the federal performance standards in subchapter K of 30 CFR Chapter VII, and the environmental protection performance standards of the regulatory program. We propose to revise this provision to be more consistent with section 508(a) of SMCRA,259 which requires that each reclamation plan include the information ‘‘necessary to demonstrate that reclamation required by the State or Federal program can be accomplished.’’ The existing rule is too limiting in that it refers only to performance standards, not to all reclamation requirements. In addition, the references to section 515 of SMCRA and subchapter K of 30 CFR Chapter VII in the existing rule are inconsistent with the principle of state primacy under section 503(a) of SMCRA,260 which specifies that a state with an approved regulatory program assumes exclusive jurisdiction over surface coal mining and reclamation operations on nonFederal, non-Indian lands within its borders, except as provided in sections 521 and 523 261 and title IV 262 of the Act. Therefore, we propose to revise paragraph (a) by deleting the references to performance standards and to section 515 of SMCRA and subchapter K of 30 CFR Chapter VII. Instead, we propose to require that each permit application include a reclamation plan showing how the applicant will comply with the reclamation requirements of the applicable regulatory program. Paragraph (b): Reclamation Timetable Section 508(a)(7) of SMCRA 263 requires the reclamation plan for each permit application include ‘‘a detailed estimated timetable for the accomplishment of each major step in the reclamation plan.’’ Existing 30 CFR 780.18(b)(1) implements this provision in part. We propose to revise the PO 00000 258 30 U.S.C. 1265.

In typical chronological order, those steps include, but are not limited to, backfilling, grading, restoration of the form of all reconstructed perennial and intermittent stream segments, soil redistribution, planting, demonstration of revegetation success, restoration of the ecological function of all reconstructed perennial and intermittent stream segments, and application for each phase of bond release. Establishment of a timetable that includes those steps should promote consistency in the application of this provision and result in a more comprehensive timetable, which would implement section 508(a)(7) of SMCRA more completely. The regulatory authority must evaluate the proposed timetable to determine whether it meets the contemporaneous reclamation requirements of section 515(b)(16) of SMCRA.264 Once approved as part of the permit, this timetable serves as a standard for evaluating compliance with the contemporaneous reclamation requirements of section 515(b)(16) of SMCRA.265 Paragraph (c): Reclamation Cost Estimate We propose to revise this paragraph, which appears at 30 CFR 780.18(b)(2) in our existing rules, by clarifying that the cost estimates must include both direct and indirect costs and by requiring that the permit applicant use current, standardized construction cost estimation methods and equipment cost guides in developing estimates of the cost of reclamation. These changes should improve the accuracy of cost estimates and increase the usefulness of these estimates to the regulatory authority in determining the amount of performance bond required under section 509 of SMCRA 266 and 30 CFR part 800. Paragraph (d): Backfilling and Grading Plan Proposed paragraph (d) corresponds to existing 30 CFR 780.18(b)(3). We propose to add more specificity to the existing rule, which requires ‘‘[a] plan for backfilling, soil stabilization, compacting, and grading, with contour maps or cross-sections that show the anticipated final surface configuration of the proposed permit area, in 264 30 U.S.C. 1265(b)(16). 265 Id. 266 30 E:\FR\FM\27JYP2.SGM U.S.C. 1259. 27JYP2 tkelley on DSK3SPTVN1PROD with PROPOSALS2 44488 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules accordance with 30 CFR 816.102 through 816.107.’’ Proposed paragraph (d)(1) would require that the reclamation plan contain a plan for backfilling the minedout area, compacting the backfill, and grading the disturbed area in accordance with 30 CFR 817.102 through 817.107 of this chapter, using the best technology currently available. It also would specify that the plan must limit compaction to the minimum necessary to achieve stability requirements unless additional compaction is necessary to reduce infiltration to minimize leaching and discharges of parameters of concern. The added language is intended to achieve a balance between minimizing compaction, which research has shown stunts the growth of most crops and woody plants,267 and the need to minimize the formation of discharges that contain sulfate and other ions that could have adverse impacts on receiving streams and their aquatic life. Proposed paragraph (d)(1) also would require that the plan be accompanied by models, contour maps, or cross-sections that show in detail the anticipated final surface elevations and configuration of the proposed permit area, including drainage patterns. The regulatory authority would use this information to determine whether the proposed plan satisfies the backfilling, grading, and surface configuration requirements of 30 CFR 816.102 through 816.107. Proposed paragraph (d)(2) would require that the plan describe in detail how the permittee will conduct backfilling and reclamation activities and handle acid-forming and toxicforming materials, if present, to prevent the formation of acid or toxic mine drainage from acid-forming and toxicforming materials within the overburden. It also would require an explanation of how the method selected will protect groundwater and surface water in accordance with 30 CFR 816.38, which contains the performance standards for handling acid-forming and toxic-forming materials. Proposed paragraph (d)(2) would implement in part the requirements in section 515(b)(3) of SMCRA 268 that surface coal mining and reclamation operations compact spoil where advisable to prevent leaching of toxic materials, cover all acid-forming and other toxic materials, and shape and grade 267 See, e.g., Hamza, M.

It also would implement, in part, section 515(b)(14) of SMCRA,269 which requires that all acid-forming materials and toxic materials be ‘‘treated or buried and compacted or otherwise disposed of in a manner designed to prevent contamination of ground or surface waters.’’ Paragraph (e): Soil Handling Plan We propose to extensively revise our existing rules concerning soils to promote salvage, preservation, and redistribution of the best available soil materials for the purpose of creating a growing medium (soil) suitable for the intended vegetation, including creation of a root zone of sufficient depth for that vegetation. Proposed paragraph (e) would include those provisions of our existing rules at 30 CFR 816.22(b) and (e) that are permitting requirements rather than performance standards in an effort to consolidate permit application information and review requirements in subchapter G rather than having them split between subchapters G (permit requirements) and K (performance standards). We propose to extensively revise our existing rules to better implement section 515(b)(5) of SMCRA,270 which states that surface coal mining operations must— remove the topsoil from the land in a separate layer, replace it on the backfill area, or if not utilized immediately, segregate it in a separate pile from other spoil and when the topsoil is not replaced on a backfill area within a time short enough to avoid deterioration of the topsoil, maintain a successful cover by quick growing plant or other means thereafter so that the topsoil is preserved from wind and water erosion, remains free of any contamination by other acid or toxic material, and is in a usable condition for sustaining vegetation when restored during reclamation, except if topsoil is of insufficient quantity or of poor quality for sustaining vegetation, or if other strata can be shown to be more suitable for vegetation requirements, then the operator shall remove, segregate, and preserve in a like manner such other strata which is best able to support vegetation. Proposed paragraph (e)(1)(i) is similar to the first sentence of existing 30 CFR 780.18(b)(4). It would require that the reclamation plan include a plan and schedule for removal, storage, and redistribution of topsoil, subsoil, and other material to be used as a final growing medium in accordance with 30 CFR 816.22. Consistent with proposed 30 CFR 816.22(f), we also propose to add a PO 00000 269 30 270 30 U.S.C. 1265(b)(14). U.S.C. 1265(b)(5).

Acceptable uses for organic matter are as a soil supplement, to promote revegetation, to assist in stream restoration, or to provide wildlife habitat. Preservation and distribution of organic matter on the regraded site would assist in meeting the requirement of section 515(b)(19) of SMCRA 271 to establish on the regraded area a diverse, effective, and permanent vegetative cover of the same seasonal variety native to the area. Our proposed rule also is consistent with the findings of an extensive literature review of reforestation on minesites in Appalachia. That review recommended that ‘‘all surface organic debris (including stumps, stems, roots, and litter), all soil layers, and the soft saprolite and weathered rock materials under the soil be removed, mixed in the process of excavating, hauling and dumping, and placed on the surface of reclaimed mine sites to a depth of 1 to 2 meters.’’ 272 Proposed paragraph (e)(1)(ii) provides that the plan must require the removal, segregation, stockpiling, and redistribution of the B and C horizons and other underlying strata or portions thereof to the extent that those horizons and strata are needed to provide the root zone required to restore premining land use capability or to comply with the revegetation requirements of 30 CFR 816.111 and 816.116. The proposed rule differs from the existing rule at 30 CFR 816.22(e) in that the existing rule provides that salvage and redistribution of these soil materials is discretionary on the part of the regulatory authority. However, the subsoil (the B and C horizons) also is important for plant growth. Plant roots extend through the topsoil into the subsoil (root zone), which provides a substantial proportion of the plant’s nutrient requirements. For example, field studies have shown that between 45 percent and 65 percent of nitrogen available to plants from the soil lies below a depth of 6 inches. During dry summer weather, many plants, especially deep-rooted plants like alfalfa and most trees, depend for their survival on moisture available in the subsoil. Alfalfa extracts 55 percent of its moisture requirements from soil 271 30 U.S.C. 1265(b)(19). C. E., J. A. Burger, C D. Barton, and J. G.

Even mediumrooted crops like wheat and corn extract up to 40 percent of their moisture requirements from soil materials deeper than one foot. Finally, many plants depend on root penetration well into the subsoil for physical support, especially where topsoil is thin. If plant roots are unable to penetrate deeply into a reclaimed subsoil, soil capability for plant growth will be degraded.273 Therefore, a failure to require salvage and redistribution of the B and C horizons under these conditions would result in a failure to restore the site to a condition in which it is capable of supporting those land uses that it was capable of supporting before any mining, as required by section 515(b)(2) of SMCRA.274 Furthermore, proposed paragraph (e)(1)(ii) is consistent with, and would improve implementation of, section 515(b)(5) of SMCRA,275 which provides that if strata other than the topsoil ‘‘can be shown to be more suitable for vegetation requirements, then the operator shall remove, segregate, and preserve in a like manner such other strata which is best able to support vegetation.’’ The U.S. District Court for the District of Columbia upheld this interpretation of section 515(b)(5) of SMCRA in 1980 in PSMRL I, Round I concerning the 1979 version of our regulations at 30 CFR 816.22(d),276 which required segregation of the B horizon and portions of the C horizon if the regulatory authority determined that those materials were necessary or desirable to ensure soil productivity: Section 515(b)(5) authorizes segregation [of materials other than topsoil] if the topsoil cannot sustain vegetation or if other strata enhance post-mining vegetation. This is essentially what the regulations command. They focus on ‘‘soil productivity,’’ and grant the regulatory authority power to require segregation if necessary to improve such productivity.277 tkelley on DSK3SPTVN1PROD with PROPOSALS2 Proposed paragraph (e)(1)(iii) would require that the plan explain how soil materials would be handled and stored to avoid contamination by acid-forming or toxic-forming materials and to minimize the loss of desirable soil characteristics during handling and 273 Alberta Transportation, ‘‘Alberta Transportation Guide to Reclaiming Borrow Excavations’’ (December 2013); pp. 5–6. 274 30 U.S.C. 1265(b)(2). 275 30 U.S.C. 1265(b)(5). 276 30 CFR 816.22(d) was subsequently redesignated as 30 CFR 816.22(e) on May 16, 1983.

These provisions mirror similar requirements in section 515(b)(5) of SMCRA.278 Proposed paragraph (e)(2) contains expanded criteria and requirements for the approval and use of soil substitutes or supplements. It differs from existing 30 CFR 816.22(b) most significantly in that the existing rule allows use of topsoil substitutes or supplements if the resulting soil medium is equal to or more suitable than the existing topsoil in terms of its capability to sustain vegetation. We propose to eliminate the provision allowing use of topsoil substitutes or supplements when the resulting growing medium (soil) is only equal to the existing topsoil in terms of its capability to sustain vegetation. Our proposed revision would improve the implementation of section 515(b)(5) of SMCRA,279 which allows use of other overburden strata in place of the topsoil only if those strata ‘‘can be shown to be more suitable for vegetation requirements.’’ Nothing in this provision of SMCRA authorizes the use of other strata in place of topsoil if the resulting medium is only equal in its ability to meet vegetation requirements. While section 515(b)(5) of SMCRA 280 is silent on the use of subsoil substitutes, we propose to apply the same standards to the use of subsoil substitutes and supplements as we do to topsoil substitutes and supplements. The subsoil is an important part of the growing medium in that, among other things, it provides the root zone required by many plants for physical support, moisture, and nutrient uptake.281 Therefore, application of the same standards for subsoil substitutes as for topsoil substitutes is appropriate to ensure that the reclaimed site is restored to a condition in which it is capable of supporting the uses that it was capable of supporting before any mining, as required by section 515(b)(2) of SMCRA.282 Proposed paragraph (e)(2)(i) explains that proposed paragraph (e)(2) would apply to all permit applicants proposing to use appropriate overburden materials as a supplement to or substitute for the existing topsoil or subsoil on the proposed permit area. Proposed paragraph (e)(2)(ii)(A) would require that the permit applicant demonstrate, and the regulatory authority find in writing, that either the quality of the existing topsoil and 278 30 U.S.C. 1265(b)(5). 279 Id. 280 Id. 281 Alberta Transportation, ‘‘Alberta Transportation Guide to Reclaiming Borrow Excavations’’ (December 2013); pp. 5–6. 282 30 U.S.C. 1265(b)(2).

Studies in Appalachia have found that native soils contain nitrogen and phosphorus in organic forms that are readily available to plants; they also contain organic carbon that is essential to soil microorganisms and nutrient cycling.283 The author of an extensive literature review of reforestation on minesites in Appalachia concluded that native soils ‘‘will be the most favorable material available on most mine sites for use in constructing mine soils for reforestation’’ and that, when use of rock spoil is necessary, the native soils, as well as stumps and woody debris, should be mixed with those spoils to enhance their chemical, biological, and physical properties.284 Proposed paragraph (e)(2)(ii)(B) would require that the permit applicant demonstrate, and the regulatory authority find in writing, that use of the alternative overburden materials, either in combination with or in place of the topsoil or subsoil, would result in a growing medium (soil) that will provide superior rooting depth in comparison to the existing topsoil and subsoil and that will be more suitable to sustain the vegetation required by the approved postmining land use and the revegetation plan than the existing topsoil and subsoil. Proposed paragraph (e)(2)(ii)(C) would require that overburden materials selected for use as a soil substitute or supplement be the best materials available in the proposed permit area to support the native vegetation to be established on the reclaimed area or the crops to be planted on that area. The demonstrations and findings required by proposed paragraphs (e)(2)(ii)(A) through (C) would, in part, improve implementation of section 283 Zipper, et al. (2012), op. cit. at 346. 284 Id.

Proposed paragraph (e)(2)(iii) would require that the regulatory authority specify suitability criteria for potential soil substitutes and supplements; chemical and physical analyses, field trials, or greenhouse tests that the applicant must conduct on potential soil substitutes and supplements; and sampling objectives, sampling techniques, and the techniques to be used to analyze the samples collected. Proposed paragraph (e)(2)(iv)(A) would require that demonstrations of the suitability of potential soil substitutes and supplements include the physical and chemical soil characteristics and root zones needed to support the type of vegetation to be established on the reclaimed area. Proposed paragraph (e)(2)(iv)(B) would require that those demonstrations include a comparison and analysis of the thickness, total depth, texture, percent coarse fragments, pH, thermal toxicity, and areal extent of the different kinds of soil horizons and overburden materials available within the proposed permit area, based upon a statistically valid sampling procedure. Proposed paragraphs (e)(2)(iii) and (iv) are intended to ensure that the determination of the suitability of potential soil substitutes and supplements is conducted in a scientifically-sound manner. Use of scientifically-invalid sampling and analytical techniques or a lack of comprehensive criteria for the evaluation and approval of potential soil substitutes and supplements could result in the establishment of an inferior growing medium on the reclaimed area that is incapable of supporting the uses that it was capable of supporting before any mining. Such a result would be inconsistent with section 515(b)(2) of SMCRA.288 It also would be inconsistent with the requirement in section 515(b)(5) of SMCRA 289 that any topsoil substitutes be shown to be more suitable for vegetation requirements than the existing soil and that any substitute materials be the best able to support vegetation. Proposed paragraph (e)(2)(v) would require that the soil handling plan include a plan for testing and evaluating overburden materials during both removal and redistribution to ensure that the permittee removes and redistributes only those overburden materials approved for use as soil substitutes or supplements. This requirement would provide a safeguard against the salvage and redistribution of overburden materials that have not been approved for use as soil substitutes or supplements. Use of unapproved materials could result in the establishment of an inferior growing medium on the reclaimed area that is incapable of supporting the uses that it was capable of supporting before any mining. Such a result would be inconsistent with section 515(b)(2) of SMCRA.290 It also would be inconsistent with the requirement in section 515(b)(5) of SMCRA 291 that any topsoil substitutes be shown to be more suitable for vegetation requirements than the existing soil and that any substitute materials be the best able to support vegetation. Paragraph (f): Surface Stabilization Plan We propose to add this paragraph to replace existing 30 CFR 780.15, which requires that the reclamation plan include an air pollution control plan for fugitive dust.

The court held that ‘‘the legislative history indicates that Congress only intended to regulate air pollution related to erosion.’’ 292 The 1983 rulemaking removed all requirements in 30 CFR 816.95 for fugitive dust control practices, including requirements for monitoring of fugitive dust to determine compliance with federal and state air quality standards. That rulemaking also changed the section heading of 30 CFR 816.95 from ‘‘Air resources protection’’ to ‘‘Stabilization of surface areas’’ and replaced the air quality performance standards formerly located in that section with soil stabilization requirements that contain no mention of fugitive dust or air quality monitoring. See 48 FR 1160–1163 (Jan. 10, 1983). However, the 1983 rulemaking did not remove the parallel permitting requirements in 30 CFR 780.15 and 784.26. Instead, we stated in the preamble to that rulemaking that we agreed with a commenter that we also needed to amend the permit application rules at 30 CFR 780.15 and 784.26 for consistency with the revisions to 30 CFR 816.95 and 817.95, and that we would do so in a subsequent independent rulemaking.293 Adoption of this proposed rule would fulfill that commitment in part by adding permit application information requirements consistent with the 1983 revisions to 30 CFR 816.95. In other words, we propose to replace the obsolete air pollution control plan requirements in existing 30 CFR 780.15 with the surface stabilization plan requirements in proposed 30 CFR 780.12(f) to correspond with the requirements in existing 30 CFR 816.95, as revised in 1983. Proposed paragraph (f) would add a permitting counterpart to the current performance standard at 30 CFR 816.95(a), which provides that all exposed surface areas must be protected and stabilized to effectively control erosion and air pollution attendant to Sfmt 4702 E:\FR\FM\27JYP2.SGM 27JYP2 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules tkelley on DSK3SPTVN1PROD with PROPOSALS2 erosion. We also propose to add crossreferences to the current dust control performance standards for roads in 30 CFR 816.150 and 816.151. Paragraph (g): Revegetation Plan We propose to extensively revise this paragraph, which appears at 30 CFR 780.18(b)(5) in our existing rules, by adding specificity for elements of the revegetation plan, by incorporating those provisions of 30 CFR 816.111 that are more appropriately considered permitting requirements rather than performance standards, and by ensuring that there is a detailed counterpart in the revegetation plan to the revegetation performance standards in 30 CFR 816.111 through 816.116, when appropriate. The various components of proposed paragraph (g) are intended to ensure compliance with or improve implementation of section 515(b)(19) of SMCRA,294 which requires that surface coal mining and reclamation operations establish ‘‘a diverse, effective, and permanent vegetative cover of the same seasonal variety native to the area of land to be affected and capable of selfregeneration and plant succession at least equal in extent of cover to the natural vegetation of the area; except, that introduced species may be used in the revegetation process where desirable and necessary to achieve the approved postmining land use plan.’’ Proposed paragraph (g)(1)(ii) would add a site preparation element to the revegetation plan to reflect extensive research documenting the adverse impacts of excessive compaction on vegetation, especially woody plants. The new element would require a description of the measures that the permittee will take to avoid compaction or, when avoidance is not possible, to minimize and alleviate compaction of the root zone during backfilling, grading, soil redistribution, and planting. In addition, we propose to require in paragraph (g)(1)(viii) that the revegetation plan identify any normal husbandry practices that the permittee intends to use and explain whether the permittee intends to conduct irrigation or apply fertilizer after the first year and, if so, for how long and to what extent. This information will assist the regulatory authority in determining whether the proposed practices are normal husbandry practices or whether they are augmentative in nature, which would necessitate restarting the revegetation responsibility period under proposed 30 CFR 816.115, which corresponds to existing 30 CFR 294 30 816.116(c). These provisions would serve as the permit application information counterpart to the performance standards in proposed 30 CFR 816.115(a)(1) and (b), which correspond to existing 30 CFR 816.116(c)(1) and (c)(4). Proposed paragraph (g)(1)(xi) would add a requirement that the revegetation plan include the measures that the permittee will take to avoid the establishment of invasive species on reclaimed areas or to control those species if they do become established. Invasive species are highly detrimental to native ecosystems, agriculture, and forestry. They have posed a problem on some minesites either because the permit improperly allowed the use of invasive non-native species or because of the reclamation practices used. We propose to add this provision to improve the implementation of section 515(b)(19) of SMCRA,295 which requires the establishment of a diverse, effective, and permanent vegetative cover of the same seasonal variety native to the area, and section 515(b)(2) of SMCRA,296 which requires restoration of mined land to a condition capable of supporting the uses it was capable of supporting before any mining. Allowing the establishment of invasive species also would be inconsistent with the fish and wildlife protection provisions of section 515(b)(24) of SMCRA.297 Moreover, proposed paragraph (g)(1)(xi) is consistent with Section 2.(a)(2)(i) and (iv) of Executive Order 13112, ‘‘Invasive Species,’’ which requires that ‘‘[e]ach Federal agency whose actions may affect the status of invasive species shall, to the extent practicable and permitted by law, . . . (i) prevent the introduction of invasive species; . . . [and] (iv) provide for the restoration of native species and habitat conditions in ecosystems that have been invaded.’’ 298 Proposed paragraph (g)(2) would require that the plan be designed to create a diverse, effective, permanent vegetative cover that is consistent with the vegetative communities described in the permit application in accordance with 30 CFR 779.19. It also would require that the plan meet the other requirements of 30 CFR 816.116(a) and (b). Proposed paragraph (g)(3) is substantively identical to the speciesselection criteria of existing 30 CFR 816.111(a)(2), (a)(4), and (b), with two exceptions.

This proposed requirement is consistent with section 515(b)(19) of SMCRA,299 which allows the use of introduced species only if they are desirable. Invasive introduced species are not desirable because they out-compete native vegetation and can have adverse impacts on fish and wildlife, which would be inconsistent with the fish and wildlife protection requirements of section 515(b)(24) of SMCRA.300 Moreover, proposed paragraph (g)(3)(i) is consistent with Section 2.(a)(2)(i) of Executive Order 13112, ‘‘Invasive Species,’’ which requires that ‘‘[e]ach Federal agency whose actions may affect the status of invasive species shall, to the extent practicable and permitted by law, . . . prevent the introduction of invasive species’’.301 Proposed paragraph (g)(3)(ii) would provide that the species selected need to be capable of stabilizing the soil surface from erosion only to the extent that control of erosion with herbaceous species is consistent with establishment of a permanent vegetative cover that resembles native plant communities in the area. We propose to add this qualifier because some level of erosion is natural and because excessive herbaceous cover can inhibit establishment of woody plants, as discussed at length elsewhere in this preamble. Proposed paragraphs (g)(4) and (g)(5) are substantively identical to existing 30 CFR 816.116(c) and (d). Both paragraphs would provide limited exceptions to the species-selection requirements of proposed paragraphs (g)(3)(i), (iv), and (v), which correspond to the speciesselection provisions of section 515(b)(19) of SMCRA.302 Proposed paragraph (g)(3) would provide an exception for temporary cover, while proposed paragraph (g)(4) would provide an exception for long-term, intensive agricultural postmining land uses. These exceptions would be consistent with section 515(b)(19) of SMCRA,303 which allows the use of introduced species ‘‘in the revegetation process where desirable and necessary to achieve the approved postmining land use plan.’’ Proposed paragraph (g)(4) also would implement section 515(b)(20) of SMCRA 304 to the extent that it provides exceptions to the requirements of section 515(b)(19) for 299 30 U.S.C. 1265(b)(19).

Proposed paragraph (g)(6) would require that a professional forester or ecologist develop and certify all revegetation plans that include the establishment of trees and shrubs. It also would require that those plans include site-specific planting prescriptions for canopy trees, understory trees and shrubs, and herbaceous ground cover compatible with establishment of those trees and shrubs. In addition, this proposed paragraph would require that the plan rely exclusively upon the use of native species unless those species are inconsistent with the approved postmining land use and that land use is implemented before the entire bond amount for the area in question has been fully released. Paragraph (h): Stream Restoration Plan We propose to add this paragraph to require that the reclamation plan expressly address in detail how the permittee will restore the form and ecological function of each segment of a perennial or intermittent stream that is proposed to be mined through under 30 CFR 780.28. The plan must conform to the requirements of 30 CFR 780.28 and 816.57. The U.S. Army Corps of Engineers may require additional onsite or offsite mitigation under section 404 of the Clean Water Act.305 tkelley on DSK3SPTVN1PROD with PROPOSALS2 Paragraph (i): Coal Resource Conservation Plan Proposed paragraph (i) corresponds to existing 30 CFR 780.18(b)(6). We propose to add language consistent with the existing coal recovery performance standard at 30 CFR 816.59. Proposed paragraph (i) would implement section 508(a)(6) of SMCRA,306 which provides that the reclamation plan must include a statement of ‘‘the consideration which has been given to maximize the utilization and conservation of the solid fuel resource being recovered so that reaffecting the land in the future can be minimized.’’ Paragraph (j): Plan for Disposal of Noncoal Waste Materials Proposed paragraph (j) corresponds to existing 30 CFR 780.18(b)(7). We propose to clarify that this requirement applies to all noncoal waste materials resulting from mining and reclamation activities, but not to coal combustion residuals such as fly ash and bottom ash. The existing rule applies to ‘‘debris, acid-forming and toxic-forming materials, and materials constituting a fire hazard.’’ We propose to delete the reference to acid-forming and toxicforming materials because proposed 30 CFR 780.22 contains the permit application information requirements for those materials. As revised, proposed paragraph (j) would apply to all noncoal waste materials covered by 30 CFR 816.89. It would serve as the permit application information counterpart to the performance standards for disposal of noncoal waste materials in 30 CFR 816.89. We also propose to require that the reclamation plan describe the type and quantity of noncoal waste materials that the permittee intends to dispose of within the proposed permit area, how the permittee intends to dispose of those materials in accordance with 30 CFR 816.89, and the locations of any noncoal waste material disposal sites within the proposed permit area, as well as the contingency plans developed to preclude sustained combustion of combustible noncoal materials. These permit application information requirements would enable the regulatory authority to evaluate the potential environmental impacts of the disposal of noncoal waste materials and ensure that the permit includes appropriate measures to protect society and the environment from the adverse effects of this aspect of surface coal mining operations, as provided in section 102(a) of SMCRA.307 Paragraph (m): Consistency With Land Use Plans and Landowner Plans In the existing rules, this paragraph appears in 30 CFR 780.23(b)(3). However, section 780.23(b) applies only in the context of the postmining land use, which is not consistent with the underlying statutory requirement at section 508(a)(8) of SMCRA.308 That provision of the Act requires that the reclamation plan describe the consideration that has been given to making the surface coal mining and reclamation operations themselves consistent with surface owner plans and applicable state and local land use plans and programs. This provision is separate and distinct from the requirement in section 508(a)(3) of the Act 309 that the reclamation plan discuss the relationship of the postmining land use to existing land use policies and plans and the comments of the surface owner. Therefore, we propose to move the provision in existing 30 CFR 780.23(b)(3) to new § 780.12(m) to ensure that, in discussing consistency 307 30 U.S.C. 1202(a).

We propose to remove the requirement in existing 30 CFR 780.14(b)(7) for maps showing each air pollution collection and control facility because that requirement is associated with regulations in 30 CFR 816.95 that the court struck down in 1980 and that we removed in 1983. Specifically, the court struck down our authority to regulate air pollution under SMCRA, except for air pollution attendant to erosion.310 See the portion of this preamble concerning our proposed removal of 30 CFR 780.15 for additional discussion. In proposed paragraph (a)(7), which corresponds to existing paragraph (b)(6), we propose to add a requirement for a map showing the location of each point at which water will be discharged from the proposed permit area to a surfacewater body and the name of that water body, consistent with equivalent requirements in sections 507(b)(10) and (14) of SMCRA.311 In proposed paragraph (a)(11), which corresponds to existing paragraph (b)(11), we propose to replace the terms ‘‘coal processing waste bank’’ and ‘‘coal processing waste dam and embankment’’ with ‘‘refuse pile’’ and ‘‘coal mine waste impounding structure’’ to employ terminology consistent with the definitions and performance standards that we adopted on September 26, 1983 (48 FR 44006). We also propose to add a reference to siltation structures, consistent with our addition of that terminology and requirements for those structures on September 26, 1983 (48 FR 44032).

We also propose to add paragraph (a)(15), which would require a map showing the location and geographic coordinates of each point at which the applicant proposes to monitor groundwater, surface water, or the biological condition of perennial and intermittent streams. The regulatory authority would need this information to determine whether the application includes a sufficient number of monitoring sites and whether those sites are adequately distributed and located to ensure that monitoring results are representative of the entire permit area, as required by proposed 30 CFR 780.23. In addition, we propose to revise existing 30 CFR 780.14(c), which we propose to redesignate as 30 CFR 780.13(b), by replacing the crossreferences to 30 CFR 780.35(c) and 816.71(b) with a cross-reference to 30 CFR 780.35 to be consistent with other changes that we are proposing to those rules. Those changes include moving the design certification requirement formerly located in section 816.71(b) to 30 CFR 780.35(b) to consolidate permitting requirements in subchapter G. The existing rules also include a cross-reference to the certification requirements in 30 CFR 816.73(c) for durable rock fills. We do not propose to include a similar cross-reference in 30 CFR 780.13(b) because we are proposing to remove 30 CFR 816.73 in its entirety, which means that durable rock fills would no longer be allowed. We propose to add paragraph (c), which would authorize the regulatory authority to require submission of the information required by paragraph (a) in a digital format, when appropriate. We invite comment on whether submission of this information in a digital format should be mandatory rather than discretionary to facilitate review and analysis by the public and the regulatory authority. 5. Why are we proposing to remove existing 30 CFR 780.15? We propose to remove existing 30 CFR 780.15 and redesignate existing 30 CFR 780.13 as 30 CFR 780.15 because the references to fugitive dust and crossreferences to 30 CFR 816.95 in existing 30 CFR 780.15 refer to provisions that VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 we removed in 1983 in response to a court decision striking down our authority to regulate air pollution under SMCRA, except for air pollution attendant to erosion. The court held that ‘‘the legislative history indicates that Congress only intended to regulate air pollution related to erosion’’ 312 and that ‘‘the Secretary’s authority to regulate [air] pollution is limited to activities related to erosion.’’ 313 The court remanded former 30 CFR 816.95 and 817.95 (1979), which contained performance standards for fugitive dust control, for revision. However, the court did not address the parallel permitting requirements at 30 CFR 780.15 and 784.26. The 1983 rulemaking removed all requirements in 30 CFR 816.95 for fugitive dust control practices, including requirements for monitoring of fugitive dust to determine compliance with federal and state air quality standards. That rulemaking also changed the section heading of 30 CFR 816.95 from ‘‘Air resources protection’’ to ‘‘Stabilization of surface areas’’ and replaced the air quality performance standards formerly located in 30 CFR 816.95 with soil stabilization requirements that contain no mention of fugitive dust or air quality monitoring. See 48 FR 1160–1163 (Jan. 10, 1983). However, the 1983 rulemaking did not remove the parallel permitting requirements in 30 CFR 780.15. Instead, we stated in the preamble to that rulemaking that we agreed with a commenter that we also needed to amend the permit application rules at 30 CFR 780.15 and 784.26 for consistency with the revisions to 30 CFR 816.95 and 817.95, and that we would do so in a subsequent independent rulemaking.314 Adoption of this proposed rule would fulfill that long-delayed commitment. In concert with the removal of 30 CFR 780.15, we propose to redesignate existing 30 CFR 780.13, which concerns blasting, as 30 CFR 780.15. 6. Section 780.16: What must I include in the fish and wildlife protection and enhancement plan? Proposed 30 CFR 780.16 is the counterpart to paragraphs (b) and (c) of existing 30 CFR 780.16. Our proposed revisions to the existing rule would provide greater specificity on the measures that the fish and wildlife protection and enhancement plan in the permit application must include. The proposed revisions would improve implementation of section 515(b)(24) of SMCRA,315 which provides that ‘‘to the extent possible using the best technology currently available,’’ surface coal mining and reclamation operations must ‘‘minimize disturbances and adverse impacts of the operation on fish, wildlife, and related environmental values, and achieve enhancement of those resources where practicable.’’ The proposed revisions also are consistent with paragraphs (a) and (d) of section 102 of SMCRA,316 which provide that two of the purposes of SMCRA are establishing ‘‘a nationwide program to protect society and the environment from the adverse effects of surface coal mining operations’’ and assuring ‘‘that surface coal mining operations are so conducted as to protect the environment.’’ Likewise, the proposed revisions to 30 CFR 780.16 are consistent with section 515(b)(23) of SMCRA,317 which requires that surface coal mining and reclamation operations ‘‘meet such other criteria as are necessary to achieve reclamation in accordance with the purposes of this Act, taking into consideration the physical, climatological, and other characteristics of the site.’’ Long-standing case law supports the Secretary’s authority to adopt these regulations 318 and provides the Secretary ‘‘great deference’’ in determining how to ensure that the Act’s provisions are enforced.319 Proposed paragraph (a) contains general requirements analogous to existing 30 CFR 780.16(b)(1) and (2). Like the existing rules, it provides that the fish and wildlife protection and enhancement plan must be consistent with the performance standards for fish and wildlife protection and enhancement at 30 CFR 816.97 and must be specific to the fish and wildlife resources of the proposed permit and adjacent areas as identified in the permit application in accordance with 30 CFR 779.20. We propose to add a requirement that the plan also comply with the specific protection and enhancement requirements of 30 CFR 780.16(b) through (e).

We propose to add these provisions in response to discussions with the U.S. Fish and Wildlife Service concerning compliance with the Endangered Species Act. Proposed paragraph (c) would contain requirements for the protection of fish and wildlife other than threatened and endangered species. It would require that the fish and wildlife protection and enhancement plan describe how, to the extent possible using the best technology currently available, the proposed operation will minimize disturbances and adverse impacts on fish, wildlife, and related environmental values, as required by section 515(b)(24) of SMCRA.320 It lists a number of measures that the fish and wildlife protection and enhancement plan must include to minimize disturbance and adverse impacts, including timing of operations to avoid or minimize disruption to wildlife and retention of forest cover and native vegetation for as long as possible. As discussed below, riparian (streamside) vegetation plays a critical role in maintaining or restoring the ecological function of a stream. Therefore, proposed paragraph (c)(3) would specify that the fish and wildlife enhancement plan must require maintenance of an intact forested buffer at least 100 feet wide between surface disturbance and a perennial or intermittent stream to the extent possible. This requirement would apply only when the stream is located in a forested area. Researchers have found that, in small, well-shaded upland streams, as much as 75 percent of the organic food base may be supplied by dissolved organic compounds or detritus such as fruit, limbs, leaves and insects that fall from the forest canopy in the riparian zone. 321 Benthic detritivores (bacteria, fungi 320 30 U.S.C. 12658(b)(24).

They pass on this energy when they are, in turn, consumed by larger benthic fauna and eventually by fish. Thus, the streamside forest functions as an important energy source for the entire aquatic food chain from headwaters to estuary.322 Furthermore, forested riparian buffers are essential to prevent excessively high water temperatures in coldwater streams and to moderate temperature variations in other streams. One study found a four-fold decline in fish density in coldwater streams after removal of the forested riparian buffer.323 Another study found that invertebrate populations in streams with forested buffers of 100 feet exhibited no change following clearcutting of the area outside the buffer zone. However, streams in watersheds in which clearcutting operations left narrower forested buffers experienced significant changes in the species diversity of invertebrate populations, with the extent of the changes correlating to buffer width.324 Studies of effective buffer widths for wildlife generally recommend wider buffers than those required for sediment control and protection of water quality. For example, recommended buffer widths for conservation of forestdwelling birds often exceed 300 feet.325 A comprehensive guide to riparian forest buffers in the Chesapeake Bay watershed provides a range of recommended minimum buffer widths for different objectives: 50 to 275 feet for wildlife habitat, 60 to 225 feet for flood mitigation, 50 to 175 feet for sediment removal, 35 to 140 feet for nitrogen removal, 20 to 60 feet for water temperature moderation, and 20 to 45 feet for bank stabilization and aquatic food web maintenance.326 The minimum 100-foot buffer width that we www.na.fs.fed.us/spfo/pubs/n_resource/buffer/ cover.htm (last accessed January 16, 2015). 322 Id. 323 P.

Therefore, the 100-foot minimum width that we have proposed for the riparian buffer is an appropriate midrange compromise that strikes a balance among property rights and the various recommended buffer widths for relevant objectives, consistent with section 102(f) of SMCRA,327 which provides that one of the purposes of SMCRA is to strike a balance between environmental protection and the need for coal production. We propose to specify that the buffer width must be measured horizontally on a line perpendicular to the stream beginning at the bankfull elevation or, if there are no discernible streambanks, the centerline of the active channel. We derived this provision primarily from Natural Resources Conservation Service Conservation Practice Standard Code 391 (‘‘Riparian Forest Buffer’’) (July 2010), which states: ‘‘Measurement shall begin at and perpendicular to the normal water line, bank-full elevation, or the top of the bank as determined locally.’’ For streams that lack defined banks, our proposed rule would adopt the standard used in a riparian buffer conservation zone model ordinance, which calls for measurement from the centerline of the stream in those circumstances.328 Another measure listed in proposed paragraph (c) is a requirement for periodic evaluation of the impacts of the operation on fish, wildlife, and related environmental values in the permit and adjacent areas. This paragraph would require that the permittee use that information to modify operations or take other action if necessary to avoid or minimize unforeseen adverse impacts on fish, wildlife, and related environmental values. Proposed paragraph (d)(1) would require that the fish and wildlife protection and enhancement plan include a description of the measures that the permit applicant proposes to implement as the best technology currently available to enhance fish, wildlife, and related environmental values both within and outside the area 327 30 U.S.C. 1202(f).

If the applicant determines that it is not practicable to implement any enhancement measures, the application would have to explain the rationale for this determination. Proposed paragraphs (d)(1)(i) through (xi) list examples of potential enhancement measures. However, the applicant may select other measures. There is no expectation that each application will include all the measures listed here. Under proposed paragraph (d)(2), implementation of fish and wildlife enhancement measures would be mandatory whenever the proposed operation would result in the long-term loss of native forest, other native plant communities, or a segment of a perennial or intermittent stream. In this context, ‘‘long-term’’ means that the permittee would not be able to correct the resource loss before expiration of the period of extended revegetation responsibility as prescribed in proposed 30 CFR 816.115. Thus, the removal of significant native forest cover and the loss of the ecological benefits associated with that cover would be considered a long-term loss, as would the burial of a perennial or intermittent stream segment by an excess spoil fill or coal mine waste disposal facility. We invite comment on whether there are other interpretations of ‘‘long-term’’ that we should consider. We also invite comment on whether the regulatory authority may consider mitigation measures approved under the authority of the Clean Water Act as satisfying the separate SMCRA requirement for mandatory enhancement measures. Acceptance may enhance coordination of permitting reviews under SMCRA and the Clean Water Act. We request that anyone with data on the effectiveness and long-term viability of Clean Water Act mitigation measures that have already been implemented submit that data to us for consideration in our decision as to whether to accept Clean Water Act mitigation measures as fish and wildlife enhancement measures under SMCRA. We also request that anyone with data on downstream impacts from coal mining and the effectiveness of Clean Water Act mitigation measures on those impacts submit that data to us for consideration. Finally, we request that anyone with data on the cumulative downstream impacts of coal mining that are not addressed by Clean Water Act mitigation measures or National Pollutant Discharge Elimination System (NPDES) permits submit that data to us for consideration. VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 Proposed paragraph (d)(2)(ii) would require that the scope of the enhancement measures be commensurate with the potential longterm adverse impact to those resources and that the measures be permanent in nature. For example, riparian corridors must be protected by conservation easements (dedicated to an appropriate agency or organization) or deed restrictions or so that the newly planted vegetation is not destroyed after bond release and termination of jurisdiction under SMCRA. We invite comment on whether our regulations should define ‘‘commensurate’’ in this context and, if so, how we should define that term. Proposed paragraph (d)(2)(iii)(A) would require that enhancement measures be implemented within the watershed in which the proposed operation is located, unless opportunities for enhancement are not available within that watershed. In the latter situation, the proposed rule would allow the permit applicant to propose enhancement measures for implementation in the nearest adjacent watershed in which enhancement opportunities exist. Proposed paragraph (d)(2)(iii)(B) would require that each regulatory program prescribe the size of the watershed for purposes of paragraph (d)(2)(iii)(A) of this section, using a generally-accepted watershed classification system. We invite comment on whether we should instead establish a standard size nationwide as part of the final rule. The HUC–12 (U.S. Geological Survey 12-digit Watershed Boundary Dataset) watershed is one possibility. Proposed paragraph (d)(2)(iv) would require that completion of mandatory enhancement measures be made a condition of permit issuance to ensure that this requirement is both enforceable and covered by the performance bond posted for the operation. Proposed paragraph (d)(3) would require that the area to be disturbed by implementation of enhancement measures be included within the proposed permit area whenever implementation of those measures would result in more than a de minimis disturbance of the surface of land outside the area to be mined. This provision would ensure that the regulatory authority can enforce implementation of those measures under the SMCRA permit and that their implementation would be covered by the performance bond for the operation. Proposed paragraph (e) would contain the U.S. Fish and Wildlife Service permit application review provisions located at existing 30 CFR 780.16(c). We propose to revise these provisions in PO 00000 Frm 00061 Fmt 4701 Sfmt 4702 44495 response to discussions with the U.S. Fish and Wildlife Service concerning compliance with the Endangered Species Act. Proposed paragraph (e)(1)(i) would require that the regulatory authority provide the fish and wildlife protection and enhancement plan developed under this section as part of the permit application to the applicable regional or field office of the U.S. Fish and Wildlife Service whenever the resource information submitted under proposed 30 CFR 779.20 includes species listed as threatened or endangered under the Endangered Species Act, critical habitat designated under that law, or species proposed for listing as threatened or endangered under that law. The proposed rule would require that the regulatory authority provide this information to the Service no later than the time that the regulatory authority provides written notice of receipt of an administratively complete permit application to the Service under proposed 30 CFR 773.6(a)(3)(ii). Under existing 30 CFR 780.16(c), the Service must request this information from the regulatory authority rather than receiving it automatically. Proposed paragraph (e)(1)(ii) is similar to existing 30 CFR 780.16(c) in that it would allow the Service to request an opportunity to review the fish and wildlife protection and enhancement plans submitted as part of other permit applications even when the resource information in those applications does not include species listed as threatened or endangered under the Endangered Species Act, critical habitat designated under that law, or species proposed for listing as threatened or endangered under that law. Under both the existing and proposed rules, the regulatory authority must provide that information to the Service within 10 days of receipt of the request. Proposed paragraph (e)(2) would specify how the regulatory authority must handle comments received from the Service and how any disagreements are to be resolved. Proposed paragraph (e)(2) generally parallels the provisions that we and the Service agreed to as a result of a formal section 7(a)(2) Endangered Species Act consultation pertaining to the approval and conduct of surface coal mining and reclamation operations under a SMCRA regulatory program. Specifically, proposed paragraphs (e)(2)(i) through (iii) would provide that if the regulatory authority does not agree with a Service recommendation that pertains to fish and wildlife or plants listed as threatened or endangered under the E:\FR\FM\27JYP2.SGM 27JYP2 44496 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules Endangered Species Act or to critical habitat designated under that law, the regulatory authority must explain the rationale for that decision in a comment disposition document and must provide a copy of that document to the pertinent Service field office. The proposed rule also would require that the regulatory authority provide a copy of that document to the appropriate OSMRE field office for informational purposes and to allow the OSMRE field office to monitor resolution of the disagreement. If the Service field office does not concur with the regulatory authority’s decision and the regulatory authority and the Service field office are subsequently unable to conclude an agreement at that level, the proposed rule allows either the regulatory authority or the Service to elevate the issue through the chain of command of the regulatory authority, the Service, and OSMRE for resolution. Proposed paragraph (e)(2)(iv) would provide that the regulatory authority may not approve the permit application until all issues are resolved in accordance with this process and the regulatory authority receives written documentation from the Service that all issues have been resolved. Like all provisions of proposed paragraph (e)(2), this provision is intended to ensure the protection of threatened and endangered species in accordance with the Endangered Species Act. 7. Section 780.19: What baseline information on hydrology, geology, and aquatic biology must I provide? tkelley on DSK3SPTVN1PROD with PROPOSALS2 Proposed paragraph (a): General Requirements Proposed paragraph (a) would require that each permit application contain information on the hydrology, geology, and aquatic biology of the proposed permit and adjacent areas in sufficient detail to assist in preparing the determination of the probable hydrologic consequences of mining under 30 CFR 780.20, preparing the hydrologic reclamation plan under 30 CFR 780.22, preparing the surface-water and groundwater monitoring plans under 30 CFR 780.23, preparing the plans for monitoring the biological condition of streams under 30 CFR 780.23, demonstrating that all reclamation required by the regulatory program can be accomplished as required by 30 CFR 773.15(b), preparing the cumulative hydrologic impact assessment under 30 CFR 780.21, and determining whether the proposed operation has been designed to prevent material damage to the hydrologic VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 balance outside the permit area as required by 30 CFR 773.15(e). Section 510(b)(3) of SMCRA 329 specifies that the regulatory authority may not approve a permit application unless the regulatory authority has ‘‘made an assessment of the probable cumulative impact of all anticipated mining in the area on the hydrologic balance specified in section 507(b).’’ This assessment is commonly referred to as the CHIA. Section 507(b)(11) of SMCRA,330 the pertinent part of the SMCRA section referenced in the quote above, requires that each permit application include— a determination of the probable hydrologic consequences of the mining and reclamation operations, both on and off the mine site, with respect to the hydrologic regime, quantity and quality of water in surface and ground water systems including the dissolved and suspended solids under seasonal flow conditions and the collection of sufficient data for the mine site and surrounding areas so that an assessment can be made by the regulatory authority of the probable cumulative impact of all anticipated mining in the area upon the hydrology of the area and particularly upon water availability. Section 510(b)(3) also specifies that the regulatory authority may not approve a permit unless the application affirmatively demonstrates and the regulatory authority finds in writing that the proposed operation ‘‘has been designed to prevent material damage to the hydrologic balance outside the permit area.’’ In addition, section 510(b)(2) of SMCRA 331 specifies that the regulatory authority may not approve a permit unless the application affirmatively demonstrates and the regulatory authority finds in writing that the ‘‘applicant has demonstrated that reclamation as required by this Act and the State or Federal program can be accomplished under the reclamation plan contained in the permit application.’’ Without sound baseline information on surface-water and groundwater quality and quantity and the biological communities in streams, the regulatory authority cannot prepare an adequate CHIA or determine whether the proposed mining operation has been designed to prevent material damage to the hydrologic balance outside the permit area. A lack of adequate baseline data and accurate mining impact analyses based on that data likewise would impair the ability of the regulatory authority to make the finding required by 30 CFR 773.15(b) and PO 00000 U.S.C. 1260(b)(3).

Proposed Paragraph (b): Information on Groundwater Proposed paragraph (b)(1) would require that each permit application include information sufficient to document seasonal variations in the quality, quantity, and usage of groundwater, including all surface discharges, within the proposed permit and adjacent areas. Currently, this provision is part of existing 30 CFR 780.21(b)(1). Proposed paragraph (b)(2) would require that the permit application include an assessment of the seasonal characteristics of any underground mine pool that is present within the proposed permit or adjacent areas unless the applicant demonstrates, and the regulatory authority finds, that the mine pool is not hydrologically connected to the proposed permit area. Proposed paragraph (b)(2) also would require that the determination of the probable hydrologic consequences of the proposed operation include a discussion of the effect of the proposed mining operation on any underground mine pools within the proposed permit and adjacent areas. In our experience, the mine pools associated with underground mines adjacent to, underlying, or overlying the proposed operation are not always properly or completely described, including the current or potential degree of hydrologic connection between the mine pool and the proposed operation. The level of detail and data collection needs to be sufficient for the reviewer to understand the complex interaction between the mine pools and the hydrology of the proposed permit and adjacent areas. Proposed paragraph (b)(3) would allow the regulatory authority to require the installation of properly-screened monitoring wells when necessary to obtain groundwater quality and quantity information sufficient to characterize seasonal variations. Properly-designed and constructed monitoring wells are essential to collection of reliable and scientifically-valid data, which section 517(b)(2) of SMCRA requires. 329 30 330 30 Frm 00062 Fmt 4701 Sfmt 4702 332 Id. 333 30 E:\FR\FM\27JYP2.SGM U.S.C. 1257(b)(11) and 1260(b)(3). 27JYP2 tkelley on DSK3SPTVN1PROD with PROPOSALS2 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules Proposed paragraph (b)(4) would expand the list of parameters in existing 30 CFR 780.21(b)(1) that must be included in the description of groundwater quality. Proposed new parameters include major anions, major cations, the cation-anion balance, hot acidity,334 total alkalinity, pH, ammonia, arsenic, cadmium, copper, nitrogen, selenium, and zinc. Our rationale for adding these parameters is that a complete characterization of the prevailing premining hydrologic balance, including water chemistry, is necessary to fully assess the impacts of the proposed operations. The additional data also would facilitate quality assurance and quality control procedures. Finally, the additional baseline data may document existing water quality or other problems and thus provide the permittee with a defense against later assertions that it has caused adverse impacts to a stream with respect to those parameters. The proposed addition of selenium and a requirement for both total dissolved solids and specific conductance (rather than either total dissolved solids or specific conductance, as in the existing regulations) reflect concerns identified in scientific studies documenting the adverse impacts that elevated concentrations of those parameters have had on aquatic life in streams in the central Appalachian coalfields. Part II of this preamble summarizes some of those studies. Proposed paragraph (b)(5) is substantively identical to the groundwater quantity information requirements in the last sentence of existing 30 CFR 780.21(b)(1). Proposed paragraph (b)(6)(i) would require that the permit applicant establish monitoring wells (or equivalent monitoring points like springs and other direct surface discharges of groundwater) at a sufficient number of locations within the proposed permit and adjacent areas to determine groundwater quality, quantity, and movement in each aquifer above or immediately below the lowest coal seam to be mined. At a minimum, for each aquifer, we propose to require monitoring points upgradient and downgradient of the proposed permit area and within the proposed permit area to ensure collection of data sufficient to fully describe baseline groundwater conditions. Proposed paragraph (b)(6)(ii) would require that the permit applicant collect 334 Hot acidity refers to the hot peroxide treatment titration method for determination of acidity. VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 water samples from the locations identified in proposed paragraph (b)(6)(i) at equally-spaced monthly intervals for a minimum of 12 consecutive months to document seasonal variations in the quality of groundwater through a complete hydrologic cycle. Proposed paragraph (b)(6)(ii) also would require that the permit applicant analyze those samples for all parameters listed in proposed paragraph (b)(4) at the same frequency. Analysis of all listed parameters would establish a comprehensive baseline for groundwater quality. Proposed paragraph (b)(6)(iii) would require that the permit applicant take the measurements listed in proposed paragraph (b)(5) at each location identified in proposed paragraph (b)(6)(i) at equally spaced monthly intervals for a minimum of 12 consecutive months to document seasonal variations in groundwater levels and to establish a comprehensive baseline for groundwater availability. Currently, regulatory authorities require anywhere from as few as three samples (high, mean, and low base flow) to multiple years of sampling. Requiring a minimum of 12 consecutive, equallyspaced monthly samples would ensure that the baseline data collected would cover the entire water year.335 Under both our existing rules and the 1979 rules, the regulatory authority could accept fewer than 12 months of data, provided that, as explained in the preamble to the 1979 rules, the maximum seasonal variation could be established by extrapolation from existing data collected within the same watershed or in a similar watershed through the use of modeling or other reasonable predictive tools.336 However, our past experience indicates that extrapolation is not a reliably accurate method to document and describe seasonal variation. Therefore, we now propose to require collection of actual data for the complete water year. Proposed paragraph (b)(6)(iv) would require that the regulatory authority extend the minimum baseline data collection period whenever data available from the National Oceanic and Atmospheric Administration or similar databases indicate that the region in which the proposed operation is located experienced severe drought (¥3.0 or lower on the Palmer Drought Severity Index 337) or abnormally high 335 The water year runs from October 1 through September 30. 336 44 FR 15034 (Mar. 13, 1979). 337 See https://www.drought.gov/drought/content/ products-current-drought-and-monitoring-droughtindicators/palmer-drought-severity-index (last accessed August 25, 2014).

During excessively wet periods, the seasonal concentrations of chemical constituents might be lower than normal because flows and water levels are higher. During severe drought periods, the concentrations of chemical constituents might be higher than normal because flows and water levels are lower. We propose to require that baseline data collection continue until the dataset includes 12 consecutive months without severe drought or abnormally high precipitation. Without this provision, the baseline data in the permit application would not be an accurate description of normal premining conditions.

During severe drought periods, the concentrations of chemical constituents might be higher than normal because flows and water levels are lower. We propose to require that baseline data collection continue until the dataset includes 12 consecutive months without severe drought or abnormally high precipitation. Without this provision, the baseline data in the permit application would not be an accurate description of normal premining conditions. Proposed paragraph (c)(5) would require that the applicant provide records of precipitation amounts for the proposed permit area, using on-site selfrecording devices. Precipitation records must be adequate to generate and calibrate a hydrologic model of the site, should the regulatory authority require such a model. This information is needed to prepare the PHC determination under proposed 30 CFR 780.20 and the surface-water runoff control plan required under proposed 30 CFR 780.29. Proposed paragraph (c)(6) would require that the applicant identify and assess all perennial, intermittent, and ephemeral streams within the permit and adjacent areas. The assessment would include a description of the physical and hydraulic characteristics of the stream channel, as well as the biological condition of each stream, and the nature of vegetation within the riparian zone. For streams that appear on the list of impaired surface waters prepared under section 303(d) of the Clean Water Act,343 it also would 342 See https://www.drought.gov/drought/content/ products-current-drought-and-monitoring-droughtindicators/palmer-drought-severity-index (last accessed August 25, 2014). 343 33 U.S.C. 1313(d).

Proposed paragraph (c)(6) would result in documentation of the premining physical and biological conditions of streams for purposes of evaluating the impacts of mining, establishing stream restoration standards, and establishing revegetation requirements for riparian corridors. tkelley on DSK3SPTVN1PROD with PROPOSALS2 Proposed Paragraph (d): Additional Information for Discharges From Previous Coal Mining Operations Proposed paragraph (d) would require that the applicant collect and analyze a one-time sample of all existing discharges from previous mining operations within the proposed permit and adjacent areas during the low baseflow season. Both the applicant and the regulatory authority would use the results of these analyses to identify any additional parameters of concern. Data from previous mining operations also can be helpful in preparing the determination of the probable hydrologic consequences of mining and the CHIA. Hydrologic data from both reclaimed and unreclaimed minesites can be extremely valuable in predicting the impacts of future mining. Proposed Paragraph (e): Biological Condition Information for Streams Proposed paragraph (e)(1) would require that each permit application include an assessment of the biological condition of each perennial and intermittent stream within the proposed permit and adjacent areas as well as an assessment of the biological condition of a representative sample of ephemeral streams within those areas. This requirement would not apply to a permit application for which the regulatory authority grants an exemption under proposed paragraph (h). Proposed paragraph (e)(2) would require that persons conducting the assessment use a multimetric bioassessment protocol approved by the state or tribal agency responsible for preparing the water quality inventory report required under section 305(b) of the Clean Water Act 344 or other scientifically-valid multimetric bioassessment protocols used by agencies responsible for implementing the Clean Water Act. Multimetric indices include metrics such as species richness, complexity, and tolerance as well as trophic measures. They provide a quantitative comparison (often referred to as an index of biological or biotic integrity) of the ecological 344 33 U.S.C. 1315(b). VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 complexity of biological assemblages relative to a regionally-defined reference condition. However, we also propose to establish minimum standards that those protocols must meet. First, the bioassessment protocol must be based upon the measurement of an appropriate array of aquatic organisms, including benthic macroinvertebrates. Benthic macroinvertebrates are particularly useful for assessing the biological condition of the stream because certain species are highly sensitive to the presence of pollutants. Furthermore, we propose to require identification of benthic macroinvertebrates to the genus level because a bioassessment protocol that identifies macroinvertebrates only to the family level may not be capable of differentiating between pollutiontolerant and pollution-intolerant genera within the same family. On the other hand, a bioassessment protocol that identifies organisms to the species level may not be consistent with available indices of biological integrity. Finally, proposed paragraph (e)(2) would require that the bioassessment protocol result in the calculation of index values for both habitat and macroinvertebrates and provide a correlation of index values to the capability of the stream to support designated uses under section 101(a) or 303(c) of the Clean Water Act, as well as any other existing or reasonably foreseeable uses. We seek comment on the effectiveness of using index scores from bioassessment protocols to ascertain impacts on existing, reasonably foreseeable, or designated uses. We also invite commenters to suggest other approaches that may be equally or more effective. Proposed Paragraph (f): Geologic Information Proposed paragraph (f) is substantively identical to the existing rules at 30 CFR 780.22(b) through (d), except as discussed below. We propose to eliminate the provision in existing 30 CFR 780.22(b)(2)(ii) that allows the regulatory authority to waive the requirement that the permit application include analyses of each stratum in the geological column for alkalinityproducing materials. We also propose to eliminate the provision in existing 30 CFR 780.22(b)(2)(iii) that allows the regulatory authority to waive the requirement that the permit application include an analysis of the coal seam for pyritic sulfur. Both analyses are necessary for a complete acid-base accounting, assessment of the potential for acid mine drainage, and prediction of the total dissolved solids content of PO 00000 Frm 00065 Fmt 4701 Sfmt 4702 44499 postmining discharges. In addition, this information is necessary to prepare an accurate determination of the probable hydrologic consequences of mining under proposed 30 CFR 780.20 and the cumulative hydrologic impact assessment under proposed 30 CFR 780.21. Finally, the information is necessary to assist the regulatory authority in determining whether reclamation is possible and whether the proposed operation will create a longterm postmining discharge requiring treatment. We invite comment on whether we should adopt provisions similar to proposed 30 CFR 777.13(b) to prescribe acceptable methodologies for the geochemical analyses required by proposed 30 CFR 780.19(f)(3)(ii) and (iii). Proposed Paragraph (g): Cumulative Impact Area Information Proposed paragraph (g) is substantively identical to existing 30 CFR 780.21(c), with the exception that we propose to clarify that the permit applicant may submit data and analyses from nearby mining operations if the site of those operations is representative of the proposed operations in terms of topography, hydrology, geology, geochemistry, and method of mining. Proposed Paragraph (h): Exception for Operations That Avoid Streams Proposed paragraph (h) would allow a permit applicant to request that the regulatory authority waive the biological condition information requirements of proposed 30 CFR 780.19(e). The regulatory authority may approve the request only if it determines that the applicant has demonstrated that the proposed operation will not mine through or bury a perennial or intermittent stream; create a pointsource discharge to any perennial, intermittent, or ephemeral stream; or modify the baseflow of any perennial or intermittent stream. Proposed Paragraph (i): Coordination With Clean Water Act Agencies Proposed paragraph (i) would require that SMCRA regulatory authorities consult with the agencies responsible for issuing permits, authorizations, and certifications under the Clean Water Act and make best efforts to minimize differences in baseline data collection points and parameters to the extent practicable and consistent with each agency’s mission, statutory requirements, and implementing regulations. Coordination could reduce the overall regulatory impact to the industry, reduce the workload of E:\FR\FM\27JYP2.SGM 27JYP2 44500 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules regulatory authorities, and expedite the permitting process. Applicants and permittees may use data already provided to or collected by a Clean Water Act agency to satisfy SMCRA requirements, provided that the data is reasonably current and of the type, scope, and quantity required for SMCRA purposes. Proposed paragraph (i) is consistent with the intent of section 713 of SMCRA,345 which, among other things, promotes coordination of regulatory activities under SMCRA and the Clean Water Act. tkelley on DSK3SPTVN1PROD with PROPOSALS2 Proposed Paragraph (j): Corroboration of Baseline Data Proposed paragraph (j) would require that the regulatory authority either corroborate a sample of the baseline information in each permit application or arrange for a third party to conduct the corroboration at the applicant’s expense. Corroboration may include, but is not limited to, simultaneous sample collection and analysis, use of field verification measurements, or comparison of application data with application or monitoring data from adjacent operations. The existing regulations at 30 CFR 777.13 already require that the permit applicant document and describe the methods and persons collecting and analyzing technical data. We interpret the existing regulations as meaning that the regulatory authority has an obligation to monitor the accuracy and completeness of data collection and analyses for permit applications. Proposed paragraph (j) would make this responsibility explicit. Proposed Paragraph (k): Permit Nullification for Inaccurate Information Proposed paragraph (k) specifies that a permit will be void from the date of issuance and have no legal effect if the permit issuance was based on substantially inaccurate baseline information. Under those circumstances, the proposed rule provides that the permittee must cease mining-related activities and immediately begin to reclaim the site. This measure would avoid or minimize the environmental harm that could result from initiation or continuation of an operation approved on the basis of substantially inaccurate data. We do not intend for this provision to apply in situations in which the application contains only minor omissions or errors. By ‘‘substantially inaccurate,’’ we mean situations such as missing or false chemical analyses of geologic strata or misrepresentation of data from another 345 30 permit application as being collected from the proposed permit and adjacent areas. Adoption of proposed paragraph (k) would be in furtherance of section 102(a) of SMCRA,346 which provides that one of the purposes of the Act is to establish a nationwide program to protect society and the environment from the adverse effects of surface coal mining operations. 8. Section 780.20: How must I prepare the determination of the probable hydrologic consequences of my proposed operation (PHC determination)? Proposed paragraph (a) would revise the requirements concerning preparation of the determination of the probable hydrologic consequences of mining in existing 30 CFR 780.21(f)(1) through (f)(3) by adding a requirement to consider the impacts of the proposed operation on the biological condition of perennial, intermittent, and ephemeral streams located within the proposed permit and adjacent areas, not just on the quantity and quality of surface water and groundwater as in the existing rule. Proposed paragraph (a)(1) would replace the requirement in existing 30 CFR 780.21(f)(3)(i) for a finding on whether the proposed operation may cause adverse impacts to the hydrologic balance with a requirement for a finding on whether the proposed operation may cause material damage to the hydrologic balance outside the permit area. These proposed changes would more closely tailor the PHC determination to both the definition of ‘‘material damage to the hydrologic balance outside the permit area’’ that we propose to add to 30 CFR 701.5 and the existing finding that the regulatory authority must make before approving a permit application under 30 CFR 773.15(e), which, in relevant part, requires a determination that the proposed operation has been designed to prevent material damage to the hydrologic balance outside the permit area. Proposed paragraph (a)(4) would require a finding on whether the proposed operation would either intercept or create aquifers in surface mine spoil or underground mine voids. Surface mining frequently results in the formation of a new aquifer in spoil that is placed in either the backfill or an excess spoil fill. This aquifer may have substantially different quality and quantity characteristics than water found in undisturbed overburden strata. Underground mine voids can store large volumes of water in what are commonly known as mine pools. The storage U.S.C. 1303.

Frm 00066 Fmt 4701 Sfmt 4702 volume and discharge rates of these pools may be orders of magnitude larger than those associated with aquifers in surface mine spoil because mine pools typically collect water from a much larger area than do surface mine spoil aquifers. Discharges from underground mine pools are frequently of relatively high volume because their recharge rate averages 0.47 gallons per minute per acre of mine voids.347 The quantity and quality of the groundwater that recharges the mine pool from overlying and underlying rock strata can significantly influence postmining water quality.348 These mine pool aquifers may discharge directly to the land surface or to groundwater systems downgradient of the aquifer. The PHC determination must consider the timing, quality, quantity, and location of these discharges to adequately assess the probable impacts of the proposed operation on the hydrologic balance. The new finding also would require evaluation of the impacts of any temporary or permanent dewatering of aquifers, including underground mine pools, on the hydrologic balance. Proposed paragraph (a)(5) would expand the finding in existing 30 CFR 780.21(f)(3)(iv) concerning what impact the proposed operation would have on specific water quality parameters to include the parameters for which baseline information would be required under proposed 30 CFR 780.19(b) and (c). Furthermore, we propose to add requirements in paragraph (a)(5) for findings on what impact the proposed operation would have on precipitation runoff patterns and characteristics; seasonal variations in streamflow; the magnitude and frequency of peak flows in perennial, intermittent, and ephemeral streams within the proposed permit and adjacent areas; and the biological condition of those streams. Finally, we propose to add a requirement in paragraph (a)(5)(iv) for a finding about the impact that any diversion of surface or subsurface flows to underground mine workings or any changes in watershed size as a result of the postmining surface configuration would have on the availability of surface water and groundwater.

They also would provide a more scientifically sound basis for development of the CHIA required by proposed 30 CFR 780.21 and the hydrologic reclamation plan required by proposed 30 CFR 780.22. Proposed paragraph (b) is substantively identical to existing 30 CFR 780.21(b)(3), with the exception that we propose to expand the conditions under which the regulatory authority may request that the applicant submit supplemental information to include those situations in which the PHC determination indicates that the proposed operation may result in adverse impacts to the biological condition of perennial or intermittent streams within the proposed permit area or the adjacent area. We also propose to clarify that the regulatory authority may request additional geochemical analyses of overburden materials and information concerning underground mine pools and their impacts. The new provisions are necessary to ensure that the PHC determination is sufficiently comprehensive to support development of the hydrologic reclamation plan required by 30 CFR 780.22 and the CHIA required by 30 CFR 780.21. Proposed paragraph (c)(1) is substantively identical to existing 30 CFR 780.21(f)(4), which requires that the regulatory authority determine whether a new or updated PHC determination is needed as part of the process of evaluating permit revision applications. We propose to add paragraph (c)(2) to clarify that the applicant must prepare a new or updated PHC determination whenever a regulatory authority review finds that one is needed. 9. Section 780.21: What requirements apply to preparation and review of the cumulative hydrologic impact assessment (CHIA)? Our existing regulations contain very few standards or criteria for preparation of the CHIA. Those regulations, which are located at 30 CFR 780.21(g)(1), provide that the regulatory authority must prepare an assessment of the probable cumulative hydrologic impacts of the proposed operation and all anticipated mining upon surface-water and groundwater systems in the cumulative impact area. The regulations further state that the assessment must be sufficient to determine, for purposes of permit approval, whether the proposed operation has been designed to prevent material damage to the hydrologic balance outside the permit area. The lack of standards or content VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 requirements for the CHIA, coupled with the lack of a definition of material damage to the hydrologic balance, is an impediment to stream protection under SMCRA because there are no objective criteria to apply. We propose to remedy that problem, in part, by establishing more detailed content requirements for the CHIA, based on our experience as the regulatory authority in Tennessee and on Indian lands and on our experience in evaluating the implementation of state regulatory programs. Our proposed requirements would improve implementation of sections 507(b)(11) and 510(b)(3) of SMCRA,349 which require that the regulatory authority prepare a CHIA and provide that the regulatory authority may not approve a permit application unless the application affirmatively demonstrates, and the regulatory authority finds in writing, that the proposed operation has been designed to prevent material damage to the hydrologic balance outside the permit area. Section 201(c)(2) of SMCRA 350 directs the Secretary, acting through OSMRE, to ‘‘publish such rules and regulations as may be necessary to carry out the purposes and provisions of the Act.’’ This provision establishes statutory authority for the enhanced CHIA regulations in this proposed rule. The more detailed CHIA content requirements that we propose to adopt are prudent measures to ensure that the CHIA is adequate to prevent the approval or renewal of permits that would result in material damage to the hydrologic balance outside the permit area. Proposed paragraph (a)(1) is substantively identical to existing 30 CFR 780.21(g)(1), with the exception that we propose to clarify that the CHIA must be in writing. We also propose to remove the sentence stating that the regulatory authority may allow the permit applicant to submit data and analyses relevant to the CHIA with the application. This sentence that we propose to delete is unnecessary because it is inherently true, whether stated or not. In addition, proposed paragraph (a)(3) effectively replaces this sentence. Proposed paragraph (a)(2) would provide that, in preparing the CHIA, the regulatory authority must consider relevant information on file for other mining operations located within the cumulative impact area or in similar watersheds. This provision is intended to ensure that the regulatory authority PO 00000 349 30 350 30 U.S.C. 1257(b)(11) and 1260(b)(3). U.S.C. 1211(c)(2). Frm 00067 Fmt 4701 Sfmt 4702 44501 considers all available information when preparing the CHIA. Proposed paragraph (a)(3) would provide that the regulatory authority may not approve a permit application until it receives the hydrologic, geologic, and biological information needed to prepare the CHIA, either from other federal and state agencies or from the applicant. This provision is consistent with similar language in the provisos at the end of section 507(b)(11) of SMCRA.351 Proposed paragraph (b) would establish detailed content requirements for the CHIA to ensure that the assessment is sufficiently comprehensive to support the finding that the regulatory authority must make under section 510(b)(3) of SMCRA 352 and 30 CFR 773.15(e) regarding whether the operation has been designed to prevent material damage to the hydrologic balance outside the permit area. The new requirements correspond to elements of the proposed definition of ‘‘material damage to the hydrologic balance outside the permit area’’ in 30 CFR 701.5. By requiring the development of permit-specific, numerical material damage criteria, they also would facilitate implementation of the prohibition in section 510(b)(3) of SMCRA and 30 CFR 773.15(e) on approval of a permit application unless the CHIA demonstrates that the proposed operation has been designed to prevent material damage to the hydrologic balance outside the permit area. Proposed paragraph (b)(1) would require that the CHIA contain a map of the cumulative impact area. The boundaries of this area may differ for surface water and groundwater, in which case proposed paragraph (b)(1)(i) would require that the map identify and display those differences. Proposed paragraphs (b)(1)(ii) through (iv) would require that the map identify the locations of all previous, current, and anticipated surface and underground mining, the locations of all baseline data collection sites under proposed 30 CFR 780.19, and designated uses of surface water under section 101(a) or 303(c) of the Clean Water Act. Proposed paragraph (b)(2) would require that the CHIA contain a description of all previous, existing, and anticipated mining within the cumulative impact area, including, at a minimum, the coal seam or seams mined, the extent of mining, and the reclamation status of each operation. 351 30 352 30 E:\FR\FM\27JYP2.SGM U.S.C. 1257(b)(11).

This description would include the quality and quantity of surface water and groundwater and seasonal variations therein; quantitative information about existing usage of surface water and groundwater, as well as information defining the quality of water required for each existing and reasonably foreseeable use of groundwater and surface water and each designated use of surface water under section 101(a) or 303(c) of the Clean Water Act; a description and map of the local and regional groundwater systems; and the biological condition of perennial, intermittent, and ephemeral streams within the proposed permit and adjacent areas. The requirements of proposed paragraph (b)(3) would not apply to the entire cumulative impact area. Proposed paragraph (b)(4) would require that the CHIA contain a discussion of any potential concerns identified in the PHC determination prepared under proposed 30 CFR 780.20 and how those concerns have been or will be resolved. Proposed paragraph (b)(5) would require that the CHIA contain a qualitative and quantitative assessment of how all anticipated surface and underground mining may impact water quality in surface water and groundwater in the cumulative impact area, expressed in terms of each baseline parameter identified under 30 CFR 780.19. Proposed paragraph (b)(6) would require that the CHIA contain criteria defining material damage to the hydrologic balance outside the permit area on a site-specific basis and that these numerical criteria be incorporated into the permit to ensure that they are enforceable. Proposed paragraphs (b)(6)(i) through (iii) would require that the criteria be expressed in numerical terms for each parameter of concern, that they take into consideration the biological requirements of any species listed as threatened or endangered under the Endangered Species Act when those species or designated critical habitat are present within the cumulative impact area, and that they identify the portion of the cumulative impact area to which the criteria apply and the locations at which impacts will be monitored. The regulatory authority may establish different criteria for subareas within the cumulative impact area when appropriate. Water quality VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 standards established under the Clean Water Act or in the NPDES permit for the operation might suffice for some parameters of concern, but NPDES permits do not address cumulative impacts and are not necessarily structured to prevent material damage to the hydrologic balance outside the permit area. We invite comment on whether the rule also should require that the regulatory authority establish lower corrective action thresholds to identify the point at which the permittee must take action to minimize the potential that adverse trends will continue and ultimately cause material damage to the hydrologic balance outside the permit area. In particular, we are interested in whether corrective action thresholds would be both more effective and more efficient in preventing material damage to the hydrologic balance outside the permit area, as required by SMCRA, and in avoiding designation of streams as impaired under section 303(d) of the Clean Water Act.353 Proposed paragraph (b)(7) would require an assessment of how all anticipated surface and underground mining may affect groundwater movement and availability within the cumulative impact area. This information is important in the determination of whether adverse impacts on groundwater would be severe enough to result in material damage to the hydrologic balance outside the permit area. Proposed paragraph (b)(8) would require an evaluation of whether the CHIA will support a finding that the operation has been designed to prevent material damage to the hydrologic balance outside the permit area, as required by 30 CFR 773.15(e) and section 510(b)(3) of SMCRA.354 This evaluation would have to contain supporting data and analyses. Proposed paragraph (b)(8) also would require that the CHIA include certain documented determinations as a prerequisite for a finding that the operation has been designed to prevent material damage to the hydrologic balance outside the permit area. Proposed paragraph (b)(8)(i) would require a determination that, during all phases of mining and reclamation and at all times of the year, variations in streamflow and groundwater availability resulting from the operation, as well as variations in the amount and concentration of parameters of concern in discharges from the operation to PO 00000 353 33 354 30 U.S.C. 1313(d).

We also are considering replacement of ‘‘would not adversely impact threatened or endangered species or designated critical habitat in violation of the Endangered Species Act’’ with ‘‘would not jeopardize the continued existence of threatened or endangered species or result in the destruction or adverse modification of designated critical habitat in violation of the Endangered Species Act.’’ The second alternative would parallel the language of existing and proposed 30 CFR 816.97(b) and 817.97(b). • Result in an exceedance of applicable water quality standards in any stream located outside the permit area. • Disrupt or preclude any existing or reasonably foreseeable use of surface water outside the permit area or any designated use of surface water under section 101(a) or 303(c) of the Clean Water Act 355 outside the permit area, except as provided in water supply replacement provisions of proposed 30 CFR 780.22(b) and 816.40. Proposed paragraph (b)(8)(ii) would require a determination that the operation has been designed to ensure that neither the mining operation nor the final configuration of the reclaimed area will result in changes in the size or frequency of peak flows from precipitation events or thaws that would cause an increase in damage from flooding, when compared with premining conditions. Proposed paragraph (b)(8)(iii) would require a determination that perennial and intermittent streams located outside the permit area but within the cumulative impact area would continue to have sufficient baseflow and recharge capacity to maintain their premining flow regime both during and after mining and reclamation.

Proposed paragraph (b)(8)(iv) would require a determination that the operation has been designed to protect the quantity and quality of water in any aquifer that significantly ensures the prevailing hydrologic balance. Proposed paragraph (c)(1) would require that the regulatory authority review each application for a significant permit revision to determine whether a new or updated CHIA is needed. This paragraph is similar to existing 30 CFR 780.21(g)(2), except that we propose to add a requirement that the regulatory authority document the review, including the analysis and conclusions, together with the rationale for the conclusions, in writing. In addition, we propose to require this review only for applications for significant permit revisions, not for all applications for any type of permit revisions as under the existing rule. We are not aware of any situation in which a non-significant permit revision application has required an update of the CHIA under the existing rules. Therefore, conducting this review of non-significant permit revision applications is not a meaningful or productive use of regulatory authority resources. Proposed paragraph (c)(2) would add a requirement that the regulatory authority reevaluate the CHIA during the permit renewal process or every 5 years, whichever is more frequent, to determine whether the CHIA remains VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 accurate and whether the material damage criteria in the CHIA and the permit are adequate to ensure that material damage to the hydrologic balance outside the permit area will not occur. This evaluation must include a review of all water monitoring data from both the operation in question and all coal mining operations within the cumulative impact area. We invite comment on whether this 5-year review frequency for water monitoring data is adequate to detect adverse trends in a timely manner or whether more frequent reviews, such as during midterm permit review, should be required. In addition, we invite comment on whether the permittee also should be required to conduct this review. Proposed paragraph (c)(3) would require preparation of a new or updated CHIA whenever the regulatory authority finds that one is needed based on the evaluation required by proposed paragraph (c)(2). Proposed paragraphs (c)(2) and (c)(3) are logical extensions of the finding that the regulatory authority must make under section 510(b)(3) of SMCRA 356 and 30 CFR 773.15(e) regarding whether the operation has been designed to prevent material damage to the hydrologic balance outside the permit area. 10. Section 780.22: What information must I include in the hydrologic reclamation plan and what information must I provide on alternative water resources? Proposed paragraph (a) would be substantively identical to the hydrologic reclamation plan requirements in existing 30 CFR 780.21(h), except as discussed below. Proposed paragraph (a)(2)(v) would replace the existing requirement for measures to avoid acid or toxic drainage with a requirement for preventive and remedial measures to avoid acid or toxic discharges to surface water and to avoid (or, if avoidance is not possible, minimize) degradation of groundwater. The new language reflects the nature of the surface mining process, which typically converts solid rock to highly-fragmented spoil, thus altering groundwater composition and quality. Proposed paragraph (a)(3) would require that the hydrologic reclamation plan address the impacts of any transfers of water among active and abandoned mines within the proposed permit and adjacent areas. The transfer of water between mines, whether intentional through direct connections or unintentional through leakage, can have substantial impacts on the PO 00000 356 30 U.S.C. 1260(b)(3). Frm 00069 Fmt 4701 availability, quality, and distribution of groundwater and surface water in the permit and adjacent areas, which in turn may have a substantial impact on users of groundwater and surface water. For example, a reduction in baseflow of a stream would reduce the assimilative capacity of the stream. In addition, increases in the hydrostatic head elevations of underground mine pools might cause blowouts or landslides or have other adverse impacts on land and water resources. Proposed paragraph (a)(4) would add a requirement for a description of the steps that the permittee will take during mining and reclamation through final bond release to protect and enhance aquatic life and related environmental values to the extent possible using the best technology currently available. This requirement would more completely implement section 515(b)(24) of SMCRA,357 which provides that surface coal mining and reclamation operations must use the best technology currently available to minimize disturbances and adverse impacts to fish, wildlife, and related environmental values to the extent possible and enhance those resources where practicable. Proposed paragraph (b) would replace and expand the alternative water source information required by existing 30 CFR 780.21(e) if the proposed operation may result in contamination, diminution, or interruption of a protected water supply. Proposed paragraph (b)(1) would require that the applicant identify alternative water sources that are available, feasible to develop, and suitable in quality and sufficient in quantity to support premining uses and approved postmining land uses. Proposed paragraph (b)(2) would prohibit any mining that would contaminate, diminish, or interrupt a protected water supply if the applicant is unable to identify any suitable alternative water sources. These provisions are intended to prevent situations in which high-quality water from a spring is replaced with well water that requires substantial treatment. When a suitable alternative water source is available, proposed paragraph (b)(3) would require that the permittee develop and install the alternative water supply on a permanent basis before adversely affecting an existing water supply protected under proposed 30 CFR 816.40. This provision would not apply if the permittee demonstrates, and the regulatory authority finds, that the proposed operation also would adversely affect the replacement supply. 357 30 Sfmt 4702 44503 E:\FR\FM\27JYP2.SGM U.S.C. 1265(b)(24). 27JYP2 44504 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules In that case, the proposed rule would require that the permittee provide a temporary replacement water supply until it is safe to install the permanent replacement water supply. Finally, proposed paragraph (b)(4) would require a description of how the applicant would provide both temporary and permanent replacements for any unexpected losses of protected water supplies in accordance with the timeframes and other requirements of proposed 30 CFR 816.40. Proposed paragraph (b) is intended to more completely implement the water supply replacement requirements of sections 717(b) and 720(a)(2) of SMCRA.358 tkelley on DSK3SPTVN1PROD with PROPOSALS2 11. Section 780.23: What information must I include in plans for the monitoring of groundwater, surface water, and the biological condition of streams during and after mining? Paragraphs (b)(1) and (2) of section 517 of SMCRA 359 provide authority for the adoption of regulations establishing monitoring requirements for surface coal mining and reclamation operations. Among other things, paragraph (b)(1) provides that ‘‘the regulatory authority shall require any permittee to . . . install, use, and maintain any necessary monitoring equipment or methods [and] evaluate results in accordance with such methods, at such locations, intervals, and in such manner as a regulatory authority shall prescribe.’’ Paragraph (b)(2) includes the following additional provisions: [F]or those surface coal mining and reclamation operations which remove or disturb strata that serve as aquifers which significantly insure the hydrologic balance of water use either on or off the mining site, the regulatory authority shall specify those— (A) monitoring sites to record the quantity and quality of surface drainage above and below the minesite as well as in the potential zone of influence; (B) monitoring sites to record level, amount, and samples of ground water and aquifers potentially affected by the mining and also directly below the lowermost (deepest) coal seam to be mined; (C) records of well logs and borehole data to be maintained; and (D) monitoring sites to record precipitation. The monitoring data collection and analysis required by this section shall be conducted according to standards and procedures set forth by the regulatory authority in order to assure their reliability and validity. Proposed 30 CFR 780.23 would establish more detailed requirements for groundwater and surface-water monitoring plans than those that appear 358 30 359 30 in existing 30 CFR 780.21(i) and (j). Thus, they would more completely implement the statutory provisions described and quoted above. Furthermore, our proposed enhanced monitoring requirements are intended to ensure that, as required by section 515(b)(24) of SMCRA,360 surface coal mining and reclamation operations are conducted so as to minimize disturbances to and adverse impacts on fish, wildlife, and related environmental values to the extent possible using the best technology currently available. Finally, our proposed enhanced monitoring requirements would be consistent with both the more comprehensive baseline information that we propose to require in 30 CFR 780.19 and the definition of ‘‘material damage to the hydrologic balance outside the permit area’’ that we propose to adopt in 30 CFR 701.5. Comprehensive baseline information and monitoring are critical to evaluating the impact of the mining operation on the hydrologic balance, which in turn is essential to preventing the occurrence of material damage to the hydrologic balance outside the permit area, consistent with section 510(b)(3) of SMCRA.361 Proposed Paragraphs (a): Groundwater Monitoring Plan Proposed paragraph (a) would include the groundwater monitoring plan requirements in existing 30 CFR 780.21(i). We propose to revise those requirements by adding more specific minimum requirements for the groundwater monitoring plan to ensure that the plan is adequate to evaluate the impacts of the mining operation on groundwater in the proposed permit and adjacent areas and to identify adverse trends in sufficient time to initiate corrective action to prevent the operation from causing material damage to the hydrologic balance outside the permit area. The following discussion highlights the more significant elements of proposed paragraph (a). Proposed paragraph (a)(1)(iii)(A) would require that each groundwater monitoring plan include monitoring wells (or equivalent monitoring points with direct groundwater discharges, such as springs) located upgradient and downgradient of the proposed operation to facilitate identification of potential mining-related changes in groundwater quantity or quality and to assist in an evaluation of whether any downgradient changes are the result of the mining and reclamation activities.

Frm 00070 Fmt 4701 Sfmt 4702 rule would require separate wells for each aquifer above or immediately below the lowest coal seam to be mined. This provision would ensure identification of impacts on each aquifer, consistent with section 517(b)(2)(B) of SMCRA, which requires monitoring of ‘‘aquifers potentially affected by the mining and also directly below the lowermost (deepest) coal seam to be mined.’’ Proposed paragraph (a)(1)(iii)(B) would require placement of monitoring wells in backfilled portions of the permit area after backfilling and grading of all or a portion of the permit area is completed. The purpose of these wells is to identify how infiltration through the spoil may alter groundwater levels and quality. The proposed rule would allow the regulatory authority to waive placement of monitoring wells in the backfilled area if it finds that wells in the backfilled area are not necessary to determine or predict the future impact of the mining operation on groundwater quality. Finally, to monitor impacts on underground mine pools, proposed paragraph (a)(1)(iii)(C) would require placement of monitoring wells in any existing underground mine workings that would have a direct hydrological connection to the proposed operation. These mine pools may serve as municipal, industrial, or residential water supplies. In addition, sudden, unplanned releases of the water in those mine pools can result in flooding damage or adverse impacts on receiving streams. Proposed paragraph (a)(1)(iv) would require that the plan describe how the monitoring data will be used to determine the impacts of the operation upon the hydrologic balance and the biological condition of perennial and intermittent streams within the permit and adjacent areas, as well as to prevent material damage to the hydrologic balance outside the permit area. Proposed paragraph (a)(1)(v) would require that the plan describe how monitoring practices will comply with the sampling, analysis, and reporting requirements of proposed 30 CFR 777.13(a) and (b) to ensure that samples are collected and analyzed in a legally and scientifically valid manner. Proposed paragraph (a)(1)(v) is consistent with the requirement in the text after section 517(b)(2)(D) of SMCRA 362 that the regulatory authority set forth standards and procedures for monitoring data collection and analysis 362 30 E:\FR\FM\27JYP2.SGM U.S.C. 1267(b)(2)(D). 27JYP2 tkelley on DSK3SPTVN1PROD with PROPOSALS2 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules to assure the reliability and validity of the data. Proposed paragraph (a)(2)(i) would require that the groundwater monitoring plan provide for the monitoring of parameters that could be affected by the proposed operation if those parameters relate to the findings and predictions in the PHC determination prepared under 30 CFR 780.20, the biological condition of perennial and intermittent streams and other surface-water bodies that receive discharges from groundwater within the proposed permit and adjacent areas, the suitability of the groundwater for existing and reasonably foreseeable uses, and the suitability of the groundwater to support the premining and postmining land uses. Monitoring of these parameters would assist the permittee and regulatory authority in preventing material damage to the hydrologic balance outside the permit area and in determining compliance with the water supply protection and postmining land use requirements of SMCRA and its implementing regulations. Proposed paragraph (a)(2)(ii) would require quarterly monitoring of 14 specific parameters, including, among others, selenium and the minimum water-quality parameters required by existing 30 CFR 780.21(i)(1) (pH, total iron, total manganese, and total dissolved solids or specific conductance). As summarized in Part II of this preamble, selenium can have deleterious effects upon fish and human health. In addition, this proposed paragraph would require quarterly monitoring of major anions (including, at a minimum, bicarbonate, chloride, and sulfate), major cations (including, at a minimum, calcium, magnesium, potassium, and sodium), and the cationanion balance. As summarized in Part II of this preamble, these anions and cations form salts that can alter water chemistry in a manner that sometimes has a substantial adverse impact on aquatic life. With respect to water quantity, proposed paragraph (a)(2)(ii) would require quarterly measurement of water levels, discharge rates, or yield rates. Existing 30 CFR 780.21(i) only requires monitoring of water levels, which may not be sufficient to fully evaluate groundwater quantity and availability in all cases. Finally, proposed paragraph (a)(2)(ii) would require quarterly monitoring of certain metals (if present in discharges from prior underground mines) and any other parameters of local significance, as determined by the regulatory authority based upon the information collected and the analyses conducted under VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 proposed 30 CFR 780.19 through 780.21. Proposed paragraph (a)(3) would require that the regulatory authority reconsider the adequacy of the groundwater monitoring plan at two points during the permit application review process. The first reconsideration would occur after the regulatory authority completes the technical review of the application. At that point, the regulatory authority may require that the permit applicant revise the plan to increase the frequency of monitoring, to require monitoring of additional parameters, or to require monitoring at additional locations, if the additional requirements would contribute to protection of the hydrologic balance. The second reconsideration would occur after preparation of the CHIA under proposed 30 CFR 780.21. At that point, the regulatory authority would be responsible for ensuring that the groundwater monitoring plan requires monitoring of all parameters for which the CHIA establishes material damage criteria; i.e., all parameters of concern. These reconsiderations are intended to ensure that the monitoring plans are designed to provide sufficiently comprehensive monitoring data to enable both the permittee and the regulatory authority to identify any adverse impacts on groundwater in time to take corrective action to prevent material damage to the hydrologic balance outside the permit area. Finally, proposed paragraph (a)(4) would modify the provision in existing 30 CFR 780.21(i)(2) that authorizes a groundwater-monitoring exception for any water-bearing stratum that does not serve as an aquifer that significantly ensures the hydrologic balance within the cumulative impact area. Specifically, proposed paragraph (a)(4) would allow a groundwater-monitoring exception for a water-bearing stratum that does not serve as an aquifer that significantly ensures the hydrologic balance within the cumulative impact area only if that stratum has no existing or foreseeable use for agricultural or other human purposes or for fish and wildlife purposes. The addition of this requirement would more fully implement the environmental protection purposes set forth in sections 102(a) and (d) of SMCRA.363 We recognize that the proposed new criterion does not appear in section 517(b)(2) of SMCRA.364 However, addition of the new criterion is appropriate because use of water for PO 00000 363 30 364 30 U.S.C. 1202(a) and (d).

We propose to revise those requirements by adding more specific minimum requirements for the surfacewater monitoring plan to ensure that the plan is adequate to evaluate the impacts of the mining operation on streams and other surface-water bodies in the proposed permit and adjacent areas and to identify adverse trends in sufficient time to initiate corrective action to prevent the operation from causing material damage to the hydrologic balance outside the permit area. The following discussion highlights the more significant elements of proposed paragraph (b). Proposed paragraph (b)(1)(ii) would require on-site measurement of precipitation amounts at specified locations within the permit area, using self-recording devices. Measurement of precipitation amounts at the minesite is an important component of the surface water runoff control plan required under proposed 30 CFR 780.29. We propose to require that precipitation measurements continue through Phase II bond release under proposed 30 CFR 800.42(c) or for any longer period specified by the regulatory authority. Phase II bond release is the point at which revegetation has been established. Proposed paragraph (b)(1)(iv) would require that, at a minimum, each surface-water monitoring plan include monitoring of point-source discharges from the proposed operation as well as monitoring points located upgradient and downgradient of the proposed permit area in each perennial and intermittent stream within the proposed permit and adjacent areas to facilitate identification of potential miningrelated changes in surface-water quantity or quality and to assist in an evaluation of whether any downgradient changes are the result of the mining and reclamation activities. This provision would be consistent with section 517(b)(2)(A) of SMCRA, which requires 365 30 366 30 E:\FR\FM\27JYP2.SGM U.S.C. 1265(b)(2).

Proposed paragraph (b)(1)(v) would require that the plan describe how the monitoring data will be used to determine the impacts of the operation upon the hydrologic balance and the biological condition of perennial and intermittent streams within the permit and adjacent areas, as well as to prevent material damage to the hydrologic balance outside the permit area. Proposed paragraph (b)(1)(vi) would require that the plan describe how surface-water monitoring practices will comply with the sampling, analysis, and reporting requirements of proposed 30 CFR 777.13(a) and (b) to ensure that samples are collected and analyzed in a legally and scientifically valid manner. Proposed paragraph (b)(1)(vi) is consistent with the requirement in the text after section 517(b)(2)(D) of SMCRA that the regulatory authority set forth standards and procedures for monitoring data collection and analysis to assure the reliability and validity of the data. Proposed paragraph (b)(2)(i) would require that the surface-water monitoring plan provide for the monitoring of parameters that could be affected by the proposed operation if those parameters relate to applicable effluent limitation guidelines under 40 CFR part 434, the findings and predictions in the PHC determination prepared under 30 CFR 780.20, the surface-water runoff control plan prepared under proposed 30 CFR 780.29, the biological condition of perennial and intermittent streams and other surface-water bodies within the proposed permit and adjacent areas, the suitability of the surface water for existing and reasonably foreseeable uses as well as designated uses under section 101(a) or 303(c) of the Clean Water Act, and the suitability of the surface water to support the premining and postmining land uses. Monitoring of these parameters would assist the permittee and regulatory authority in preventing material damage to the hydrologic balance outside the permit area and in determining compliance with the water supply protection and postmining land use requirements of SMCRA and its implementing regulations. Proposed paragraph (b)(2)(ii) would require quarterly monitoring of 15 specific parameters, including, among others, selenium and the minimum VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 water-quality parameters required by existing 30 CFR 780.21(j)(2)(i) (pH, total iron, total manganese, total suspended solids, and total dissolved solids or specific conductance). As summarized in Part II of this preamble, selenium can have deleterious effects upon fish and human health. In addition, this proposed paragraph would require quarterly monitoring of major anions (including, at a minimum, bicarbonate, chloride, and sulfate), major cations (including, at a minimum, calcium, magnesium, potassium, and sodium), and the cation-anion balance. As summarized in Part II of this preamble, these anions and cations form salts that can alter water chemistry in a manner that sometimes has a significant adverse impact on aquatic life. With respect to water quantity, proposed paragraphs (b)(2)(ii)(A) and (iii)(B), like existing 30 CFR 780.21(j)(2)(i), would require quarterly measurement of flow rates. We propose to require use of generallyaccepted professional flow measurement techniques, rather than subjective visual observations that involve no actual measurements and that will vary from observer to observer. Finally, proposed paragraph (b)(2)(ii) would require quarterly monitoring of certain metals (if present in discharges from prior underground mines) and any other parameters of local significance, as determined by the regulatory authority based upon the information collected and the analyses conducted under proposed 30 CFR 780.19 through 780.21. Proposed paragraph (b)(2)(iii) would not require that point-source discharges be monitored for the parameters listed in proposed paragraph (b)(2)(ii). Instead, as in existing 30 CFR 780.21(j)(2)(ii), the proposed rule would defer to the National Pollutant Discharge Elimination System permitting authority’s determinations of which parameters must be monitored. We invite comment on whether, in the final rule, we should require monitoring of some or all of the parameters listed in proposed paragraph (b)(2)(ii) in pointsource discharges to establish a more definitive connection between discharges from the minesite and trends observed at downgradient monitoring locations. To promote coordination of permitting and monitoring requirements under SMCRA and the Clean Water Act, proposed paragraph (b)(2)(iv) would require that the surface-water monitoring plan be revised to include any site-specific monitoring requirements imposed by the National Pollutant Discharge Elimination System permitting authority or the agency PO 00000 Frm 00072 Fmt 4701 Sfmt 4702 responsible for administration of section 404 of the Clean Water Act.367 This provision recognizes that this information may not be available at the time of application for the SMCRA permit and, thus, may need to be added later via a permit revision. Proposed paragraph (b)(3) would require that the regulatory authority reconsider the adequacy of the surfacewater monitoring plan at two points during the permit application review process. The first reconsideration would occur after the regulatory authority completes the technical review of the application. At that point, the regulatory authority may require that the permit applicant revise the plan to increase the frequency of monitoring, to require monitoring of additional parameters, or to require monitoring at additional locations, if the additional requirements would contribute to protection of the hydrologic balance. The second reconsideration would occur after preparation of the CHIA under proposed 30 CFR 780.21. At that point, the regulatory authority would be responsible for ensuring that the surface-water monitoring plan requires monitoring of all parameters for which the CHIA establishes material damage criteria; i.e., all parameters of concern. These reconsiderations are intended to ensure that the monitoring plans are designed to provide sufficiently comprehensive monitoring data to enable both the permittee and the regulatory authority to identify any adverse impacts on surface water in time to take corrective action to prevent material damage to the hydrologic balance outside the permit area. Proposed Paragraph (c): Biological Condition Monitoring Plan Proposed paragraph (c)(1) would require that each permit application include a plan for monitoring the biological condition of perennial and intermittent streams within the proposed permit area and the adjacent area. The proposed rule would require that the plan be adequate to evaluate the impacts of the mining operation on the biological condition of those streams and to determine in a timely manner whether corrective action is needed to prevent the operation from causing material damage to the hydrologic balance outside the permit area. Proposed paragraph (c)(2)(i) would specify that the plan must require use of a multimetric bioassessment protocol that meets the requirements of proposed 30 CFR 780.19(e)(2). In essence, this provision requires use of a multimetric 367 33 E:\FR\FM\27JYP2.SGM U.S.C. 1344. 27JYP2 tkelley on DSK3SPTVN1PROD with PROPOSALS2 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules bioassessment protocol approved by the state or tribal agency responsible for preparing the water quality inventory report required under section 305(b) of the Clean Water Act 368 or other scientifically-valid, multimetric bioassessment protocols used by agencies responsible for implementing the Clean Water Act. The bioassessment protocol must be based upon the presence or absence, population levels, and biomass of an appropriate array of aquatic organisms, including benthic macroinvertebrates. It must require identification of macroinvertebrates to the genus level because a bioassessment protocol that requires identification of aquatic organisms only to the family level may not be capable of differentiating between pollutiontolerant and pollution-intolerant genera within the same family, while a bioassessment protocol that identifies organisms to the species level may not be consistent with available indices of biological integrity. Finally, the protocol must result in the calculation of index values for both habitat and macroinvertebrates and provide a correlation of index values to the capability of the stream to support designated uses under section 101(a) or 303(c) of the Clean Water Act. Proposed paragraph (c)(2)(ii) would require that the plan identify biological condition monitoring locations in each perennial and intermittent stream within the proposed permit and adjacent areas. Proposed paragraph (c)(2)(iii) would require that the plan establish a sampling frequency that must be no less than annual, but not so frequent as to unnecessarily deplete the populations of the species being monitored. Proposed paragraph (c)(2)(iv) would provide that the plan must require submission of biological condition monitoring data to the regulatory authority on an annual basis. Proposed paragraph (c)(3) would require that the regulatory authority reconsider the adequacy of the biological condition monitoring plan after completing preparation of the CHIA under proposed 30 CFR 780.21. The proposed rule would require that, if necessary, the regulatory authority issue an order to the applicant to revise the plan to correct any deficiencies. The monitoring requirements in proposed paragraph (c) would assist in more completely implementing section 515(b)(24) of SMCRA,369 which requires that surface coal mining and reclamation operations be conducted so as to minimize disturbances to and 368 33 U.S.C. 1315(b). 369 30 U.S.C. 1265(b)(24).

Proposed paragraph (c) also would provide a means of implementing the definition of ‘‘material damage to the hydrologic balance outside the permit area’’ that we propose to adopt in 30 CFR 701.5, which relies in part upon designated uses of surface water under section 101(a) or section 303(c) of the Clean Water Act. The biological condition of perennial and intermittent streams and other surface waters determines whether those waters are capable of attaining their designated uses. Proposed Paragraph (d): Exceptions Proposed paragraph (d)(1) would allow potential permit applicants to request that the regulatory authority modify the groundwater and surfacewater monitoring plan requirements of proposed paragraphs (b) and (c) and modify or waive the biological condition monitoring plan requirements of proposed paragraph (c) if the proposed permit area includes only lands eligible for remining. The proposed rule would allow the regulatory authority to approve the request if it determines that an alternative monitoring plan will be adequate to monitor the impacts of the proposed operation on groundwater and surface water, based upon an evaluation of the quality of groundwater and surface water and the biological condition of the receiving stream at the time of application. The exception for remining operations would provide an incentive to mine and reclaim previously mined areas without the use of public funds. Streams in the vicinity of previously mined areas also are likely to be of lower quality than streams in unmined watersheds because of the adverse impacts of previous mining. Proposed paragraph (d)(2) would allow permit applicants to request that the regulatory authority waive the biological condition monitoring plan requirements of proposed paragraph (c) if the applicant demonstrates, and the regulatory authority finds in writing, that the proposed operation will not mine through or bury a perennial or intermittent stream; create a pointsource discharge to any perennial, intermittent, or ephemeral stream; or modify the baseflow of any perennial or intermittent stream. If the applicant meets all requirements except the one concerning a point-source discharge, the proposed rule would allow the regulatory authority to approve limiting the biological condition monitoring plan PO 00000 Frm 00073 Fmt 4701 Sfmt 4702 44507 requirements to only the stream that will receive the point-source discharge. Proposed Paragraph (e): Coordination With Clean Water Act Agencies Proposed paragraph (e) would require that SMCRA regulatory authorities consult with the agencies responsible for issuing permits, authorizations, and certifications under the Clean Water Act and make best efforts to minimize differences in monitoring locations and reporting requirements and to share data to the extent practicable and consistent with each agency’s mission, statutory requirements, and implementing regulations. Coordination could reduce both costs and the overall regulatory impact to the industry, as well as improving regulatory efficiency. In addition, the proposed requirement would be consistent with the intent of the regulatory coordination provisions of section 713 of SMCRA.370 12. Section 780.24: What requirements apply to the postmining land use? Proposed 30 CFR 780.24 would consolidate the requirements for approval of postmining land uses that appear in existing 30 CFR 780.23(b), 816.133(b), and 816.133(c). We also propose to add a surface mining counterpart to the interpretive rules concerning postmining land use changes in existing 30 CFR 784.200(a) and 817.200(d)(1). In addition, we propose to revise existing 30 CFR 780.24 to improve consistency with SMCRA and its legislative history and to more completely implement the environmental protection purposes of SMCRA, including the fish and wildlife protection and enhancement requirements of section 515(b)(24) of SMCRA,371 while remaining mindful of the requirement in section 508(a)(3) of SMCRA 372 to consider the comments of the surface owner and state and local governments and agencies. Our proposed revisions to the existing requirements also are consistent with section 515(b)(23) of SMCRA,373 which provides that surface coal mining and reclamation operations must ‘‘meet such other criteria as are necessary to achieve reclamation in accordance with the purposes of this Act, taking into consideration the physical, climatological, and other characteristics of the site.’’ 370 30 371 30 U.S.C. 1303.

Section 515(b)(2) of SMCRA 374 requires that surface coal mining and reclamation operations ‘‘restore the land affected to a condition capable of supporting the uses which it was capable of supporting prior to any mining, or higher or better uses of which there is a reasonable likelihood.’’ Section 508(a)(3) of SMCRA 375 requires that each reclamation plan include a statement of ‘‘the use which is proposed to be made of the land following reclamation, including a discussion of the utility and capacity of the reclaimed land to support a variety of alternative uses.’’ Combining these two statutory provisions, proposed paragraph (a)(1) would require that each permit application include both a description and a map of the proposed postmining land use or uses and a discussion of the utility and capability of the reclaimed land to support a variety of other uses, including the uses that the land was capable of supporting before any mining, as identified in the narrative analysis required under 30 CFR 779.22. Proposed paragraph (a)(2) would require that the land use or uses be described in terms of the categories listed in our definition of ‘‘land use’’ in 30 CFR 701.5, which would assist the regulatory authority in determining compliance with provisions of our regulations that are tied to land use; e.g., alternative postmining land uses, revegetation standards, and exceptions from approximate original contour restoration requirements, and provide a baseline for application of these provisions on a national basis. Proposed paragraph (a)(3) would require that the application explain how the proposed postmining land use is consistent with existing state and local land use policies and plans. Addition of this requirement would be consistent with section 508(a)(3) of SMCRA,376 which requires that the reclamation plan include an explanation of the relationship of the proposed postmining land use to existing land use policies and plans. That section of SMCRA also requires that the application include comments from state and local governments or agencies that would have to approve or authorize the proposed land use. Furthermore, section 515(b)(2) of SMCRA 377 prohibits the approval of alternative postmining land uses that are ‘‘inconsistent with restore the land affected to a condition capable of supporting the uses which it was capable of supporting prior to any mining, or higher or better uses of which there is 374 30 U.S.C. 1265(b)(2).

Proposed paragraph (a)(4) is substantively identical to the corresponding existing rule at 30 CFR 780.23(c). Proposed paragraph (a)(5) is substantively identical to the corresponding existing rule at 30 CFR 780.23(b)(1) with the exception that the proposed rule clarifies that the permit applicant must identify any support facilities (not just activities as in the existing rule) needed to achieve the postmining land use. (Support facilities are equipment repair areas, mine offices, parking lots, and other surface areas upon which are sited structures, facilities, or other property or material resulting from or incident to the activities listed in paragraph (a) of the definition of ‘‘surface coal mining operations’’ in 30 CFR 700.5.) The regulatory authority needs this information when evaluating whether the proposed postmining land use can be achieved and in deciding whether to allow mining-related structures to be retained as part of the postmining land use. Proposed paragraph (a)(6)(i) would specify that the application must provide the demonstration required under proposed paragraph (b)(1) if the applicant proposes to restore the proposed permit area or a portion thereof to a condition capable of supporting a higher or better use or uses rather than to a condition capable of supporting the use or uses that the land supported before any mining. This provision is substantively identical to existing 30 CFR 780.23(b)(2) except as discussed in the preamble to proposed paragraph (b) below. Proposed paragraph (a)(6)(ii) would require that an applicant requesting approval of a higher or better alternative postmining land use disclose any monetary compensation, item of value, or other consideration offered to the landowner by the applicant or the applicant’s agent in exchange for the landowner’s agreement to a postmining land use that differs from the premining use. Adoption of this provision is supported by section 515(b)(2) of SMCRA, which requires that surface coal mining and reclamation operations— Jkt 235001 PO 00000 Frm 00074 Fmt 4701 Sfmt 4702 reasonable likelihood, so long as such use or uses do not present any actual or probably hazard to public health or safety or pose any actual or probable threat of water diminution or pollution, and the permit applicants’ declared proposed land use following reclamation is not deemed to be impractical or unreasonable, inconsistent with applicable land use policies and plans, involves unreasonable delay in implementation, or is violative of Federal, State, or local law. Disclosure of whether a landowner has been provided with or is reasonably expected to be provided with compensation or other consideration for any postmining land use changes would allow the regulatory authority to better understand whether the proposed postmining land use change is one that the landowner genuinely desires on its own merits and is reasonably likely to be achieved, or whether the landowner agreed to the land use change for shortterm financial gain or other reasons. This type of short-term land use decision-making is contrary to the broader purposes identified in SMCRA, such as ‘‘protect[ing] society and the environment from the adverse effects of surface mining coal operations’’ in section 102(a) and assuring that ‘‘operations are conducted as to protect the environment’’ in section 102(d). Proposed Paragraph (b): What requirements apply to the approval of alternative postmining land uses? Existing 30 CFR 780.23(b)(2) provides that the application must include all materials needed for approval of an alternative postmining land use under 30 CFR 816.133 if the proposed postmining land use differs from the premining use. Existing 30 CFR 816.133(b) further provides that the ‘‘premining uses of land to which the postmining land use is compared shall be those uses which the land previously supported, if the land has not been previously mined and has been properly managed.’’ In new section 780.24, we propose to require compliance with the alternative postmining land use approval requirements only when the applicant or permittee proposes to restore the land to a condition capable of supporting higher or better uses (a term that we define in 30 CFR 701.5) rather than to a condition capable of supporting the uses that it could support before any mining. The proposed language better tracks the underlying statutory provision in section 515(b)(2) of SMCRA,378 as quoted above. In addition, it is consistent with the legislative history of section 508(a) of SMCRA: 379 378 30 379 30 E:\FR\FM\27JYP2.SGM U.S.C. 1265(b)(2). U.S.C. 1258(a). 27JYP2 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules tkelley on DSK3SPTVN1PROD with PROPOSALS2 The description [of premining land use capability] is to serve as a benchmark against which the adequacy of reclamation and the degradation resulting from the proposed mining may be measured. It is important that the potential utility which the land had for a variety of uses be the benchmark rather than any single, possibly low value, use which by circumstances may have existed at the time mining began.380 By requiring approval only when the change is to a higher or better use, our proposed rule also would avoid unnecessary paperwork on the part of permit applicants and conserve oftenscarce regulatory authority resources. We propose to delete the provision in existing 30 CFR 816.133(b) requiring that the land be properly managed before the premining land use may be compared with the proposed alternative postmining land use. There is no statutory counterpart to this provision of the existing rule, nor is it supported by the legislative history of SMCRA. Furthermore, the criteria for approval of proposed alternative postmining land uses in existing 30 CFR 816.133(c) bear no relationship to whether the land was properly managed before mining. In addition, proper management is a subjective determination. To the extent that this provision could be construed as requiring that the regulatory authority reject a proposed higher or better postmining land use that involves less intensive management than the premining use, the existing rule is inconsistent with the preamble to our definition of ‘‘land use’’ in 30 CFR 701.5, which states that the land use categories in the definition are not hierarchical.381 Consistent with that statement, the same rulemaking defined ‘‘higher or better uses’’ as meaning ‘‘postmining land uses that have a higher economic value or nonmonetary benefit to the landowner or the community than the premining land uses.’’ We are not proposing any changes to that definition. Therefore, the provision in existing 30 CFR 816.133(b) requiring that the land be properly managed before the premining land use may be compared with the proposed alternative postmining land use has no statutory basis and, in any case, is not feasible. Proposed paragraph (b) combines existing 30 CFR 780.23(b)(2), which requires that the permit application include all materials needed for approval of an alternative postmining land use under 30 CFR 816.133, with the alternative postmining land use approval criteria of 30 CFR 816.133(c). Proposed paragraph (b)(1) sets forth permit application requirements, while proposed paragraph (b)(2) contains requirements applicable to the regulatory authority’s decision-making process. In essence, proposed paragraph (b)(1), like existing 30 CFR 780.23(b)(2), requires that the permit applicant submit a demonstration that the request for an alternative postmining land use meets the criteria for approval, while proposed paragraph (b)(2), like existing 30 CFR 816.133(c), specifies when the regulatory authority may approve a request for an alternative postmining land use. Proposed paragraph (b)(1) would retain the criteria in the corresponding existing rules at 30 CFR 816.133(c) for approving alternative postmining land uses, while requiring that the permit applicant demonstrate compliance with both those criteria and several new criteria intended to promote environmental protection and restoration of fish and wildlife habitat consistent with section 515(b)(24) of SMCRA 382 and the purposes in paragraphs (a), (d), and (f) of section 102 of SMCRA.383 Addition of the new criteria also would be consistent with section 515(b)(23) of SMCRA,384 which requires that surface coal mining and reclamation operations ‘‘meet such other criteria as are necessary to achieve reclamation in accordance with the purposes of this Act, taking into consideration the physical, climatological, and other characteristics of the site.’’ As previously stated, proposed paragraph (b)(1)(i) would retain the provision in the corresponding existing rules at 30 CFR 816.133(c)(1) that there must be a reasonable likelihood of achievement of the proposed higher or better alternative postmining land use. However, we propose to expand upon this requirement by adding language that would require the applicant to document that a reasonable likelihood of achieving the higher or better use exists through submission of, for example, real estate and construction contracts, plans for installation of any necessary infrastructure, procurement of any necessary zoning approvals, landowner commitments, economic forecasts, and studies by land use planning agencies, as applicable. The additional language would flesh out the requirement in section 515(b)(2) of SMCRA 385 that there be a reasonable likelihood of achievement of the 380 S.

In the past, approved alternative postmining land uses have not been implemented on some reclaimed minesites, including some sites for which the regulatory authority approved a variance from approximate original contour restoration requirements for the purpose of achieving a particular alternative postmining land use. Our proposed rule changes concerning the reasonable likelihood of achievement of the alternative postmining land use are intended to prevent recurrences of situations in which the regulatory authority approves an alternative postmining land use that has little chance of being implemented in the reasonably foreseeable future. The proposed rule changes thus would improve compliance with the conditions for approval of higher or better uses under section 515(b)(2) of SMCRA 386 and the approximate original contour restoration requirements of section 515(b)(3) of SMCRA.387 We propose to add paragraphs (b)(1)(iii)(E) through (G) to better implement the environmental protection purposes in paragraphs (a), (d), and (f) of section 102 of SMCRA 388 and the prohibition in section 510(b)(3) of SMCRA 389 on the approval of any permit application unless the regulatory authority finds that the operation has been designed to prevent material damage to the hydrologic balance outside the permit area. Specifically, these proposed paragraphs would require that the applicant for an alternative postmining land use demonstrate that the proposed use would not— • Result in changes in the size or frequency of peak flows from the reclaimed area to the extent that the changes would cause an increase in damage from flooding compared to the conditions that would exist if the land were restored to a condition capable of supporting the uses that it was capable of supporting before any mining. • Cause the total volume of flow from the reclaimed area, during every season of the year, to vary in a way that would preclude any existing or reasonably foreseeable use of surface water or groundwater or any designated use of surface water under section 101(a) or 303(c) of the Clean Water Act.390 • Cause a change in the temperature or chemical composition of the water 386 Id. 382 30 U.S.C. 1265(b)(24). 383 30 U.S.C. 1202(a), (d), and (f). 384 30 U.S.C. 1265(b)(23). 385 30 U.S.C. 1265(b)(2).

These proposed provisions are substantively identical to the corresponding existing rules at 30 CFR 816.133(c), with the exception of the proposed requirement that the finding be in writing and the addition of the new and modified criteria in paragraph (b)(1) as discussed above. Proposed Paragraph (c): What requirements apply to permit revision applications that propose to change the postmining land use? Proposed paragraph (c) would provide that, consistent with the decision in PSMRL I, Round II,392 permittees may use the permit revision process to change the postmining land use after permit issuance. The proposed rule would specify that the application for a permit revision must be processed as a significant revision if the permittee proposes to restore the land to a condition capable of supporting higher or better uses rather than to a condition capable of supporting the uses that it was capable of supporting before any mining. Proposed paragraph (c) would provide a surface mining counterpart to the interpretive rules for underground mines at 30 CFR 784.200 and 817.200(d)(1), which specify that the requirements for approval of an alternative postmining land use may be met via the permit revision process rather than as part of the original permit application. We do not now interpret our existing surface mining rules as prohibiting permittees from submitting permit revision applications to change the postmining land use after permit issuance, nor have we interpreted those rules as doing so in the past. Therefore, the only effect of proposed paragraph (c) would be to require that a proposed change to a higher or better postmining land use be processed as a significant revision. As provided in 30 CFR 391 Id. 392 PSMRL I, Round II, 1980 U.S. Dist. LEXIS 17660 at *20 (D.D.C. 1980), 19 Env’t Rep. Cas. (BNA) 1477. VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 774.13(a)(2), an application for a significant permit revision must comply with the public notice and public participation requirements that apply to an application for a new permit. Unlike existing 30 CFR 784.200 and 817.200(d)(1), which classify any change in postmining land use as a significant permit revision, we propose to apply this requirement only to a proposed change to a higher or better use. A change from one postmining land use that the land was capable of supporting prior to mining to another postmining land use that the land was capable of supporting prior to mining would no longer require approval as an alternative postmining land use, nor would a request for such a change need to be processed as a significant permit revision. Our proposed rule would improve consistency with section 515(b)(2) of SMCRA,393 which requires that surface coal mining and reclamation operations ‘‘restore the land affected to a condition capable of supporting the uses which it was capable of supporting prior to any mining, or higher or better uses of which there is a reasonable likelihood.’’ The statutory provision distinguishes only between uses that the land was capable of supporting before mining and higher or better uses; i.e., it establishes criteria for approval of higher or better uses, but no criteria for approval of any of the uses that the land was capable of supporting before mining. Proposed Paragraph (d): What restrictions apply to the retention of mining-related structures? Proposed paragraph (d) would establish new requirements pertinent to the retention of mining-related structures in support of the postmining land use. First, the applicant or permittee would have to demonstrate, and the regulatory authority would have to find in writing, that the size and characteristics of mining-related structures (other than roads and impoundments) proposed for retention for potential use as part of the postmining land use are consistent with and proportional to the needs of the postmining land use. For example, retention of an entire coal preparation plant building as a storage facility for an agriculture or silvicultural postmining land use would be disproportionate to the needs for the postmining land use. Second, the amount of bond required for the permit must include the cost of removing the structure and reclaiming the land to a condition capable of supporting the premining uses. Third, the reclamation plan must specify that the permittee will remove any structure not in use as part of the approved postmining land use by the end of the revegetation responsibility period and reclaim the land upon which it was located. These measures are intended to ensure that only mining-related structures with a bona fide role in supporting the postmining land use are retained. These provisions should minimize the number of mining-related structures that are retained, ostensibly to support the postmining land use, but that are abandoned after final bond release and become safety hazards, attractive nuisances, or a visual blight on the landscape. Thus, proposed paragraph (d) would more fully implement section 102(a) of SMCRA,394 which provides that one of the purposes of SMCRA is to protect society and the environment from the adverse effects of surface coal mining operations. In addition, section 515(b)(2) of SMCRA 395 allows the approval of higher or better postmining land uses only if they do not present any actual of probable hazard to public health or safety. Logically, the same requirement should apply to retention of mining-related structures that did not exist prior to mining. Proposed Paragraph (e): What special provisions apply to previously mined areas? Proposed paragraph (e) would contain the postmining land use requirements for previously mined areas, as that term is defined in 30 CFR 701.5. They do not differ substantively from the corresponding requirements in the last sentence of the existing rules at 30 CFR 816.133(b) except for the proposed addition of a requirement that the revegetation plan require the use of native tree and shrub species for revegetation of all portions of the proposed permit area that were forested at the time of application or that would revert to forest under conditions of natural succession, provided that the planting of trees and shrubs on those lands would not be inconsistent with achievement of the proposed postmining land use. The added requirement would more fully implement section 515(b)(19) of SMCRA,396 which requires establishment of a diverse, effective, permanent vegetative cover of the same seasonal variety native to the area, and the fish and wildlife protection and 394 30 U.S.C. 1202(a).

Section 780.25: What information must I provide for siltation structures, impoundments, and refuse piles? tkelley on DSK3SPTVN1PROD with PROPOSALS2 Changes To Conform With the 1983 Revisions to Definitions and Performance Standards On September 26, 1983 (48 FR 44006), we revised the definitions and performance standards in our regulations relating to coal mine waste to be more consistent with the terminology used by the Mine Safety and Health Administration (MSHA). As we stated at 48 FR 44009, ‘‘[i]t is undesirable to have two regulatory programs for the same subject that contain conflicting standards or which use fundamentally different terminology.’’ Among other things, we adopted definitions of three new terms in 30 CFR 701.5. Coal mine waste is defined as ‘‘coal processing waste and underground development waste.’’ Impounding structure is defined as ‘‘a dam, embankment, or other structure used to impound water, slurry, or other liquid or semi-liquid material.’’ Refuse pile is defined as ‘‘a surface deposit of coal mine waste that does not impound water, slurry, or other liquid or semiliquid material.’’ The latter two terms are consistent with the terminology of MSHA’s regulations. ‘‘Refuse pile’’ replaces the term ‘‘coal processing waste bank’’ that we used in our previous regulations, while the term ‘‘impounding structure’’ includes, but is not limited to, all structures that our rules previously referred to as coal processing waste dams or embankments. In concert with the new definition of coal mine waste, we revised our performance standards at 30 CFR 817.71 through 817.74 to eliminate the language that combined underground development waste with excess spoil for purposes of performances standards for underground mines. Because the definition of coal mine waste includes underground development waste, we revised our regulations to specify that the disposal of underground development waste is subject to the performance standards for refuse piles at 30 CFR 817.83 rather than the performance standards for the disposal of excess spoil that applied under the old rules. However, we did not revise our permitting requirements in a similar fashion at that time. Therefore, we now propose to modify 30 CFR parts 780 and 397 30 U.S.C. 1265(b)(24). VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 784 to harmonize the terminology in those rules with our 1983 changes to the definitions and performance standards concerning coal mine waste. In essence, we propose to (1) replace the term ‘‘coal processing waste banks’’ with ‘‘refuse piles’’ and (2) replace the term ‘‘coal processing waste dams and embankments’’ with references to coal mine waste impounding structures. Proposed Paragraph (a): General Requirements In addition to the changes in terminology, we propose to revise existing paragraph (a)(1)(iii) to require that the general plan for each proposed siltation structure, impoundment, or refuse pile include the hydrologic and geologic information needed to assess the hydrologic impact of the structure. The existing rule requires submission of only ‘‘preliminary’’ hydrologic and geologic information. We propose to remove the word ‘‘preliminary’’ because preliminary information typically would not be sufficient to assess the hydrologic impact of a proposed structure. We propose to revise existing paragraph (a)(1)(iv) to require that the general plan for each proposed siltation structure, impoundment, or refuse pile contain a report describing the results of a geotechnical investigation of the potential effect on the structure if subsurface strata should subside as a result of past, current, or future underground mining operations beneath or within the proposed permit and adjacent areas. Geotechnical investigations may include site reconnaissance, drilling, or some combination of these with geophysical investigations (ground-penetrating radar, seismic investigations, etc.). The existing rule requires only a survey describing the potential effect of subsidence resulting from past underground mining operations. A survey alone would provide insufficient information to evaluate the potential effects of subsidence. Therefore, to promote long-term structural stability, we propose to require a geotechnical investigation instead of a survey and we propose to require consideration of the potential effects of subsidence from past, existing, and future underground mining operations, beneath or within the proposed permit and adjacent areas, not just the potential effects of past underground mining operations within an unspecified area. The design needs to ensure that the structure will be capable of withstanding all potential impacts of any subsidence that may occur during the life of the proposed structure. We PO 00000 Frm 00077 Fmt 4701 Sfmt 4702 44511 propose to add the reference to the proposed permit and adjacent areas to ensure that the investigation includes all underground mining operations that have the potential to cause subsidence that may affect the proposed structure, not just operations within the proposed permit area. Finally, we propose to specify that the investigation report must identify design and construction measures that would prevent adverse subsidencerelated impacts on the structure whenever impacts of that nature are a possibility. In short, proposed paragraph (a)(1)(iv) is intended to protect against failure of the impoundment embankment or other impoundment failures as a result of subsidence. Impoundment stability, especially for large impoundments, is important to protect the public, private and public property, and the environment from the adverse effects of flooding and other consequences of impoundment failure, consistent with the purposes of SMCRA in paragraphs (a) and (d) of section 102 of the Act.398 We propose to redesignate existing paragraph (a)(1)(v) as paragraph (a)(1)(vi) and add a new paragraph (a)(1)(v) to require that the general plan for each impoundment include an analysis of the potential for the impoundment to drain into subjacent underground mine workings, together with an analysis of the impacts of such drainage. The Martin County Slurry Spill incident in Martin County, Kentucky on October 11, 2000, illustrates the magnitude of environmental damage that can result when impounded coal refuse slurry breaks through into adjacent underground mine workings that open to the surface. In this case, the mine openings discharged 306 million gallons of slurry into two tributaries of the Tug Fork River (Coldwater Fork and Wolf Creek). The slurry covered nearby residents’ yards to a depth of as much as 5 feet, visibly polluted more than 100 miles of waterways, including the Big Sandy and Ohio Rivers, and devastated aquatic life in 70 miles of stream. Six public water intakes were adversely affected and alternative water supplies had to be arranged for 27,000 residents. Cleanup costs were approximately $59 million.399 Proposed paragraph (a)(1)(v) is intended to ensure that all types of 398 30 U.S.C. 1202(a) and (d). https://www.sourcewatch.org/ index.php?title=Martin_County_sludge_spill (last accessed February 4, 2015) and https:// www.jackspadaro.com/news_articles/2003/10_12_ 03/herald-leader10_12_03.html (last accessed February 4, 2015). 399 See E:\FR\FM\27JYP2.SGM 27JYP2 tkelley on DSK3SPTVN1PROD with PROPOSALS2 44512 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules impoundments constructed for coal mining purposes are designed to prevent similar breakthroughs.

We propose to revise the introductory text of existing paragraph (a)(2) for clarity and redesignate that text as paragraph (a)(2)(i). Proposed paragraph (a)(2)(i) would specify that the detailed design plan requirements of proposed paragraph (a)2)(ii) would apply to all structures meeting the MSHA criteria of 30 CFR 77.216(a), as well as to all structures that meet the Significant Hazard Class or High Hazard Class criteria for dams in NRCS publication Technical Release No. 60, ‘‘Earth Dams and Reservoirs,’’ regardless of whether those structures meet the MSHA criteria of 30 CFR 77.216(a). We propose to revise redesignated paragraph (a)(2)(i) to update the incorporation by reference of the NRCS publication ‘‘Earth Dams and Reservoirs,’’ Technical Release No. 60 (210–VI–TR60, October 1985), by replacing the reference to the October 1985 edition with a reference to the superseding July 2005 edition. Consistent with the terminology in the newer edition, we propose to replace references to Class B or C dam criteria with references to Significant Hazard Class or High Hazard Class dam criteria, respectively. Only the terminology has changed—the actual criteria remain the same as before. The newer publication is not available from the National Technical Information Service, but is available online from the NRCS (the successor to the Soil Conservation Service). Consequently, we propose to delete the ordering information pertinent to the National Technical Information Service and replace it with the Internet address at which the publication may be reviewed and from which it may be downloaded without charge. We also propose to update the address and location of our administrative record room and the Internet address information for the National Archives and Records Administration. 400 30 In addition, we propose to redesignate existing paragraphs (a)(2)(i) through (iv) as paragraphs (a)(2)(ii)(A) through (D) and add introductory text to proposed paragraph (a)(2)(ii). The introductory text is a revised version of the last sentence of the introductory text of existing paragraph (a)(2), modified to be consistent with proposed paragraph (a)(2)(i). As it currently exists, redesignated paragraph (a)(2)(ii)(B) requires that the detailed design plan include any geotechnical investigation, design, and construction requirements. This language is ambiguous because it does not identify the geotechnical investigation, design, and construction requirements to which it refers. Therefore, we propose to revise redesignated paragraph (a)(2)(ii)(B) to require that the detailed design plan for any structure that meets the applicability provisions of proposed paragraph (a)(2)(i) incorporate any design and construction measures identified in the geotechnical investigation report prepared under 30 CFR 780.25(a)(1)(iv) as necessary to protect against potential adverse impacts from subsidence resulting from underground mine workings underlying or adjacent to the structure. These measures might include grouting or backstowing of mine voids or surface mining of seams within the impoundment safety zone. In short, proposed paragraph (a)(2)(ii)(B) would operate in conjunction with proposed paragraph (a)(1)(iv) to protect against failure of the impoundment embankment or other impoundment failures as a result of subsidence. Impoundment stability, especially for large impoundments, is important to protect the public, private and public property, and the environment from the adverse effects of flooding and other consequences of impoundment failure, consistent with the purposes of SMCRA in paragraphs (a) and (d) of section 102 of the Act.401 We propose to reinstate former paragraph (a)(3), which was erroneously removed as part of the codification process for a rule published December 12, 2008 (73 FR 75814). This paragraph contains detailed design plan requirements for structures not covered under paragraph (a)(2).

Frm 00078 Fmt 4701 Sfmt 4702 propose to revise existing paragraph (c)(2) by replacing the term ‘‘Mine Safety and Health Administration’’ with a citation to 30 CFR 77.216(a), which contains the MSHA impoundment criteria to which paragraph (c)(2) refers. As revised, proposed paragraph (c)(2) would require that plans for impoundments meeting MSHA criteria comply with MSHA’s impoundment design requirements at 30 CFR 77.216– 2. We propose to delete the requirement that those plans also comply with 30 CFR 77.216–1. The requirement that we propose to delete is not germane to permit applications and plans because it contains signage requirements that apply only to impoundments that already exist or are under construction. In the second sentence, we propose to delete an obsolete cross-reference to paragraph (a). We also propose to revise paragraph (c)(2) to clarify that the requirement that the permit application include the plan submitted to MSHA applies only to those portions of the plan that are complete at the time of submission of the SMCRA permit application. Impoundment plans normally are submitted to MSHA in stages; they may not be complete or even started at the time that the applicant submits an application for the SMCRA permit. SMCRA-related permit application information requirements are sufficiently comprehensive that the regulatory authority does not need the MSHA plan to process the SMCRA permit application or to ensure the stability of proposed structures. We propose to redesignate existing paragraph (f) as paragraph (c)(4). That paragraph applies only to impoundments that meet certain criteria in Technical Release No. 60 or the MSHA criteria of 30 CFR 77.216(a). It has no relevance to the other structures to which 30 CFR 780.25 applies (lowhazard impoundments and refuse piles). Therefore, it is more appropriate to include the stability analysis requirements of existing paragraph (f) as part of proposed paragraph (c), which applies only to impoundments, including coal mine waste impoundments. We also propose to revise this paragraph to be consistent with the terminology in the July 2005 edition of Technical Release No. 60 by replacing references to Class B or C dam criteria with references to Significant Hazard Class or High Hazard Class dam criteria, respectively. Only the terminology would change; the actual criteria would remain the same as before. Finally, we propose to revise this paragraph to clarify that the stability analyses that it requires must address E:\FR\FM\27JYP2.SGM 27JYP2 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules tkelley on DSK3SPTVN1PROD with PROPOSALS2 static, seismic, and post-earthquake (liquefaction) conditions because those conditions are all part of a comprehensive stability analysis. Proposed Paragraph (d): Coal Mine Waste Impoundments and Refuse Piles As discussed in the introductory portion of the preamble to this section, we propose to modify 30 CFR parts 780 and 784 to harmonize the terminology in those rules with our 1983 changes to the definitions and performance standards concerning coal mine waste. In essence, ‘‘refuse pile’’ would replace the term ‘‘coal processing waste bank’’ as used in existing parts 780 and 784, while the term ‘‘impounding structure’’ would include all structures that existing parts 780 and 784 refer to as coal processing waste dams or embankments. We also use the term ‘‘coal mine waste impoundment’’ to refer to the impounding structure in combination with the basin behind the impounding structure. We propose to combine existing paragraph (d), which contains design requirements for coal processing waste banks, and existing paragraph (e), which contains design requirements for coal processing waste dams and embankments, into a revised paragraph (d) that uses the newer terminology. Proposed paragraph (d) would apply to any application that proposes to place coal mine waste in a refuse pile or impoundment or use coal mine waste to construct an impounding structure. We are adding the language concerning use of coal mine waste to construct an impounding structure because proposed paragraph (d) is the permitting counterpart of the performance standards for coal mine waste disposal in 30 CFR 816.81 through 816.84. Section 816.84 applies to both impounding structures constructed of coal mine waste and impounding structures intended to impound coal mine waste. Our proposed revision would expand the scope of proposed paragraph (d) to coincide with the scope of the corresponding performance standards. Proposed paragraph (d)(1) corresponds to existing paragraph (d), which requires that coal processing waste banks be designed to comply with the requirements of 30 CFR 816.81 through 816.84. Proposed paragraph (d)(1) would require that refuse piles (the successor term to ‘‘coal processing waste banks’’) be designed to comply with the requirements of 30 CFR 780.28, 816.81, and 816.83. We propose to delete the cross-reference to 30 CFR 816.84 found in existing paragraph (d) because proposed paragraph (d)(1) would pertain only to refuse piles, not VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 to the impounding structures to which 30 CFR 816.84 applies. The proposed deletion is not a substantive change because the corresponding provision of the existing rules does not pertain to impounding structures either, despite the cross-reference. We propose to add the cross-reference to 30 CFR 780.28 to emphasize the need for compliance with that section whenever a refuse pile would be located in or within 100 feet of a perennial or intermittent stream. Proposed paragraph (d)(2) corresponds to existing paragraph (e), which requires that coal processing waste dams and embankments be designed to comply with the requirements of 30 CFR 816.81 through 816.84, among other things. Proposed paragraph (d)(2)(i) would require that impounding structures constructed of or intended to impound coal mine waste (the successor terminology to ‘‘coal processing waste dams and embankments’’) be designed to comply with the requirements of 30 CFR 780.28, 816.81, and 816.84. We propose to delete the cross-reference to 30 CFR 816.83 found in existing paragraph (e) because proposed paragraph (d)(2) would pertain only to impounding structures, not to the refuse piles to which 30 CFR 816.83 applies. The proposed deletion is not a substantive change because the corresponding provision of the existing rules does not pertain to refuse piles either, despite the cross-reference. We also propose to add a cross-reference to the impoundment requirements of 30 CFR 816.49(a) and (c). This proposed addition likewise is not a substantive change because 30 CFR 816.84(b)(1) already includes an identical cross-reference to 30 CFR 816.49(a) and (c), which would apply by operation of the cross-reference to 30 CFR 816.84 in proposed paragraph (d)(2)(i). We propose to add this crossreference only as a matter of clarity and ease of use. Finally, we propose to add the crossreference to 30 CFR 780.28 to emphasize the need for compliance with that section whenever an impounding structure constructed of or intended to impound coal mine waste would be located in or within 100 feet of a perennial or intermittent stream. While coal mine waste impoundments may not be retained as permanent impoundments, they typically are converted to refuse piles and retained as permanent features, which means that the stream segment that they cover is not restored. Hence, proposed paragraph (d)(2)(i) and proposed 30 CFR 780.28 would apply the same requirements to coal mine waste impoundments as would apply to refuse piles with respect PO 00000 Frm 00079 Fmt 4701 Sfmt 4702 44513 to the approval of such structures in perennial or intermittent streams. Proposed paragraph (d)(2)(ii) would require that the design plan for any impounding structure constructed of or intended to impound coal mine waste comply with the MSHA requirements of 30 CFR 77.216–2 if the structure meets the criteria of 30 CFR 77.216(a). The corresponding provision of existing paragraph (e) also required compliance with 30 CFR 77.216–1. We propose to delete this cross-reference because 30 CFR 77.216–1 does not include any design requirements. Instead, that rule consists solely of MSHA requirements for signage for existing impoundments and impoundments under construction. Those requirements are not relevant to preparation of plans or permit applications for proposed impoundments or impounding structures. Proposed paragraph (d)(2)(ii) would retain the requirement that each plan for an impounding structure comply with 30 CFR 77.216–2, which contains MSHA design requirements for impoundments and impounding structures. Proposed paragraph (d)(2)(iii) is substantively identical to the corresponding portion of existing paragraph (e), which requires that the application include a geotechnical investigation of the foundation area and that the investigation be planned and supervised by an engineer or engineering geologist. We propose to redesignate existing paragraphs (e)(1) through (4), which establish minimum requirements for that investigation, as paragraphs (d)(2)(iii)(A) through (D). Proposed paragraph (d)(2)(iv) would require that the design ensure that at least 90 percent of the water stored in the impoundment during the design precipitation event will be removed within a 10-day period. This requirement is substantively identical to existing 30 CFR 816.84(e). We propose to move it to 30 CFR 780.25(d)(2)(iv) as part of our ongoing efforts to move permitting requirements currently located in subchapter K to subchapter G. 14. Section 780.28: What additional requirements apply to proposed activities in, through, or adjacent to streams? Proposed 780.28 would establish standards for the review and approval of permit applications that propose to conduct surface mining activities in or through a perennial, intermittent, or ephemeral stream or that would disturb the surface of lands within 100 feet of a perennial, intermittent, or ephemeral stream. Consequently, we propose to move the permitting aspects of the E:\FR\FM\27JYP2.SGM 27JYP2 tkelley on DSK3SPTVN1PROD with PROPOSALS2 44514 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules stream buffer zone rule, which is currently codified at 30 CFR 816.57(a) as part of the performance standards in subchapter K, to 30 CFR 780.28, which would be part of the permitting requirements of subchapter G. Existing 30 CFR 816.57(a) provides that the regulatory authority may authorize activities on the surface of lands within 100 feet of a perennial or intermittent stream only upon finding that (1) the activities will not cause or contribute to the violation of applicable State or Federal water quality standards and will not adversely affect the water quantity and quality or other environmental resources of the stream, and (2) if there will be a temporary or permanent stream-channel diversion, it will comply with 30 CFR 816.43. Part II of this preamble summarizes the impacts of surface coal mining operations on streams, as documented by scientific studies. Our proposed rule is intended to prevent or minimize the adverse impacts documented in those studies. The permitting requirements and performance standards in SMCRA contain limited direct references to streams, but SMCRA is replete with requirements to minimize or prevent adverse impacts on fish, wildlife, related environmental values, the quantity and quality of surface water and groundwater, and the hydrologic balance. See sections 507(b)(10), (11) and (14); 508(a)(9) and (13); 510(b); 515(b)(2), (4), (9), (10), (14), (17), and (24); 515(c)(4); 515(e)(3); 516(b)(4); and 516(b)(9) through (12).402 To the extent that proposed 30 CFR 780.28 pertains to the impact of surface coal mining and reclamation operations on streams outside the permit area, section 510(b)(3) of SMCRA,403 which prohibits issuance of a permit unless the applicant demonstrates, and the regulatory authority finds, that the proposed operation has been designed to prevent material damage to the hydrologic balance outside the permit area, provides authority for this proposed rule. In addition, section 102 of SMCRA 404 repeatedly identifies environmental protection as one of the purposes of SMCRA. In particular, section 102(a) 405 states that one of the purposes of SMCRA is to ‘‘establish a nationwide program to protect society and the environment from the adverse effects of 402 30 U.S.C. 1257(b)(10), (11), and (14); 1258(a)(9) and (13); 1260(b); 1265(b)(2), (4), (9), (10), (14), (17), and (24); 1265(c)(4) and (e)(3); 1266(b)(4) and (b)(9) through (12). 403 30 U.S.C. 1260(b)(3). 404 30 U.S.C. 1202. 405 30 U.S.C. 1202(a).

Section 201(c)(2) of SMCRA 410 provides that the Secretary of the Interior, acting through OSMRE, shall ‘‘publish and promulgate such rules and regulations as may be necessary to carry out the purposes and provisions of the Act.’’ In an en banc ruling, the U.S. Court of Appeals for the District of Columbia Circuit upheld the Secretary’s authority to promulgate rules under the authority of section 201(c) of SMCRA 411 that impose permitting requirements in addition to those set forth in sections 507 and 508 of SMCRA: 412 ‘‘We hold that the Act’s explicit listings of information required of permit applicants are not exhaustive, and do not preclude the Secretary from requiring the states to secure additional information needed to ensure compliance with the Act.’’ 413 The court found that the Secretary’s conclusion that additional information beyond that explicitly required in the Act was needed to effectively implement the Act was entitled to some deference.414 Furthermore, the U.S. District Court for the District of Columbia has held that ‘‘[a] court should sustain regulations when they reasonably relate to the purpose of the legislation.’’ 415 The U.S.C. 1202(c).

The proposed regulations also would implement section 515(b)(23) of SMCRA,416 which provides that surface coal mining and reclamation operations must ‘‘meet such other criteria as are necessary to achieve reclamation in accordance with the purposes of this Act, taking into consideration the physical, climatological, and other characteristics of the site.’’ In addition, the measures that we propose to adopt in 30 CFR 780.28 receive support from section 515(b)(2) of SMCRA,417 which requires that surface coal mining and reclamation operations ‘‘restore the land affected to a condition capable of supporting the uses which it was capable of supporting prior to any mining, or higher or better uses of which there is a reasonable likelihood.’’ Perennial and intermittent streams provide important fish and wildlife habitat, which almost always is one of the uses that the land was capable of supporting before mining. Section 515(b)(10) of SMCRA 418 also provides statutory authority for proposed 30 CFR 780.28. In relevant part, section 515(b)(10) of SMCRA requires that surface coal mining and reclamation operations ‘‘minimize the disturbances to the prevailing hydrologic balance at the mine-site and in associated offsite areas and to the quality and quantity of water in surface and ground water systems both during and after surface coal mining operations and during reclamation by . . . (G) such other actions as the regulatory authority may prescribe.’’ Paragraphs (b)(10)(B)(i) and (b)(24) of section 515 of SMCRA 419 provide support for the buffer zone protections that proposed 30 CFR 780.28 would afford to perennial and intermittent streams. Section 515(b)(10)(B)(i) of SMCRA,420 which, in relevant part, requires that surface coal mining operations be conducted ‘‘so as to prevent, to the extent possible using the best technology currently available, additional contributions of suspended solids to streamflow, or runoff outside the permit area,’’ provides the primary 416 30 U.S.C. 1265(b)(23).

This proposed paragraph is an informational provision that would be consistent with section 702(a) of SMCRA,422 which provides that ‘‘[n]othing in this Act shall be construed as superseding, amending, modifying, or repealing’’ the Clean Water Act, any rule or regulation adopted under the Clean Water Act, or any state laws enacted pursuant to the Clean Water Act. Proposed paragraph (a) would operate in tandem with proposed 30 CFR 773.17(h), which would add a new permit condition requiring that the permittee obtain all necessary authorizations, certifications, and permits in accordance with Clean Water Act requirements before conducting any activities that require approval, authorization, or certification under the Clean Water Act. Permit conditions are directly enforceable under SMCRA. Therefore, addition of the permit condition in proposed 30 CFR 773.17(h) would mean that the SMCRA regulatory authority must take enforcement action if the permittee does not obtain all necessary Clean Water Act authorizations, certifications, and permits before beginning any activity under the SMCRA permit that also requires approval or authorization under the Clean Water Act. Proposed Paragraph (b): When must I comply with this section? Proposed paragraph (b)(1) would apply 30 CFR 780.28 to permit applications to conduct surface mining activities in or through a perennial, intermittent, or ephemeral stream or on the surface of lands within 100 feet, measured horizontally, of perennial or intermittent streams.423 The 100-foot 421 30 U.S.C. 1265(b)(24).

The preamble to proposed 30 CFR 816.57(a) explains the rationale for the 100-foot buffer zone width. Activities include, but are not limited to, mining through or diverting streams; constructing sedimentation ponds, excess spoil fills, and coal mine waste disposal facilities in or near streams; and constructing stream crossings for roads and utilities, as well as the full range of mining and reclamation activities that the application may propose to take place outside the stream channel but on the surface of lands within 100 feet of the stream. Proposed paragraph (b)(2), in combination with proposed paragraph (e)(2) and 30 CFR 816.57, would prohibit mining-related activities in or within 100 feet of perennial and intermittent streams unless the applicant demonstrates, and the regulatory authority finds in writing, that the proposed activity would not (i) preclude any premining use or any designated use under the Clean Water Act of the affected stream segment following the completion of mining and reclamation; (ii) result in the conversion of the affected stream segment from intermittent to ephemeral, from perennial to intermittent, or from perennial to ephemeral; (iii) cause or contribute to a violation of water quality standards under the Clean Water Act; or (iv) cause material damage to the hydrologic balance outside the permit area. Proposed paragraph (b)(2)(iv) would duplicate the finding required by 30 CFR 773.15(e). Proposed paragraphs (b)(2)(i) through (iii) are similar to subsets of the definition of material damage to the hydrologic balance outside the permit area, but they differ from the definition of that term and 30 CFR 773.15(e) in that they would apply within the permit area as well as outside it. Proposed paragraphs (b)(2)(i) and (ii) would apply to stream segments within the permit area only after the completion of mining and reclamation, consistent with section 515(b)(10) of SMCRA,424 which provides for minimization, not prevention, of disturbances to the prevailing hydrologic balance at the minesite. To enhance fish and wildlife habitat, as required by section 515(b)(24) of SMCRA,425 proposed paragraph (b)(3)(i) would require that the permit application include plans for establishment of a riparian corridor at least 100 feet wide on each side of a 424 30 425 30 PO 00000 U.S.C. 1265(b)(10).

The preamble to proposed 30 CFR 780.16 explains why we selected the minimum 100-foot width for the riparian corridor. Proposed paragraph (b)(3)(ii) would require that disturbed areas within the corridor be planted with native species, including species adapted to and suitable for planting in riparian zones within that corridor. It also would require use of native trees and shrubs in previously forested areas or in areas that would revert to forest under conditions of natural succession. Creation of a riparian corridor populated with native species is part of the best technology currently available to minimize adverse impacts on fish, wildlife, and related environmental values and to achieve enhancement of those resources, as required by section 515(b)(24) of SMCRA.427 Nothing in proposed paragraph (b)(3) would require planting of hydrophilic species in riparian corridors or portions of riparian corridors that are incapable of providing the necessary moisture or other growing conditions. In those situations, proposed paragraph (b)(3)(ii) would require that the riparian corridor be planted with native species appropriate to the conditions. Proposed paragraph (b)(3)(iii) would provide that the proposed riparian corridor requirement would not apply to prime farmland historically used for cropland because 30 CFR 785.17(e)(1) provides that the postmining land use of prime farmland historically used for cropland must be cropland. The proposed riparian corridor requirement also would not apply to situations in which revegetation would be incompatible with an approved postmining land use that is implemented during the revegetation responsibility period before final bond release. Finally, the riparian corridor requirement would not apply to stream segments buried beneath an excess spoil fill or a coal mine waste disposal facility pursuant to proposed paragraph (d). Proposed Paragraph (c): What additional requirements apply to an application that proposed to mine through or divert a perennial, intermittent, or ephemeral stream? Proposed paragraph (c)(1) would require that the proposed postmining drainage pattern of perennial, 426 See the discussion of proposed 30 CFR 780.16(c) in this preamble for an explanation of how this distance must be measured. 427 30 U.S.C. 1265(b)(24).

In addition to its ecological benefits, this requirement would better implement the requirement in section 515(b)(3) of SMCRA 428 that the permittee ‘‘restore the approximate original contour of the land.’’ The proposed rule would allow the regulatory authority to approve deviations from the premining drainage pattern when necessary to ensure stability, to promote enhancement of fish and wildlife habitat consistent with sections 515(b)(24) and 516(b)(11) of SMCRA,429 or to prevent or minimize excessive downcutting (deepening) of reconstructed stream channels. For example, additional meanders may be needed to minimize channel erosion and downcutting when restoring streams in areas with a badlands-type topography that existed prior to mining. Proposed paragraph (c)(2) would establish additional requirements for permit applications that propose to mine through or permanently or temporarily divert a perennial or intermittent stream. Proposed paragraph (c)(2)(i) would reiterate that the applicant must meet the requirements of proposed paragraphs (a) through (c)(1). Proposed paragraph (c)(2)(ii) would require that the applicant demonstrate that there is no reasonable alternative that would avoid mining through or diverting the stream. Proposed paragraph (c)(2)(iii) would require that the operation be designed to minimize the extent to which the stream will be mined through or diverted. Proposed paragraph (c)(2)(iv) would require that the applicant demonstrate that the techniques in the reclamation plan will restore the form and ecological function of the affected stream segment, as required by 30 CFR 816.57(b). Proposed paragraph (c)(2)(iv)(A) would require the selective placement of aquitards (barriers to groundwater infiltration) within the backfill or fill when necessary to restore perennial and intermittent streams. Placement of a layer of lower-permeability spoil or other material near the surface but below the root zone for trees and shrubs could provide the subsurface flow needed to restore flow in perennial and intermittent stream segments. Construction of aquitards would have the additional benefit of quickly removing water that otherwise would have infiltrated the fill and could have emerged as leachate with undesirable concentrations of total dissolved solids 428 30 429 30 or other parameters that could degrade downstream waters. Proposed paragraph (c)(2)(iv)(B) would require that the permit application include a separate bond calculation for the costs of restoring the ecological function of the stream. It also would require that, before permit issuance, the permit applicant post a surety bond, a collateral bond, or a combination of surety and collateral bonds to cover that cost. A self-bond is not appropriate to guarantee restoration of a stream’s ecological function because of the risk that the company may cease to exist during the time required to accomplish that restoration. In addition, a self-bond does not require that the permittee file financial instruments or collateral with the regulatory authority, nor is there any third party obligated to complete the reclamation or pay the amount of the bond if the permittee defaults on reclamation obligations. Proposed paragraph (c)(2)(v) would require that the applicant comply with the stream restoration and streamchannel diversion design requirements in existing 30 CFR 816.43. As part of our effort to consolidate permitting requirements in subchapter G of our regulations, we propose to move the stream-channel diversion design provisions in the last sentence of existing 30 CFR 816.43(a)(3) and in paragraphs (b)(2) through (b)(4) of existing 30 CFR 816.43 to 30 CFR 780.28(c)(2)(v) and (vi). We also propose to extend the design requirements of proposed paragraph (c)(2)(v)(A) and the design certification requirements of proposed paragraph (c)(2)(vi) to perennial and intermittent stream channels to be restored after the completion of mining. Our existing rules do not address restored stream channels, an oversight that we propose to correct because there is no legal or scientific basis for the absence of standards for the restoration of stream channels. Restored stream channels and permanent stream-channel diversions are equally important in terms of their value to the fish, wildlife, and related environmental values protected by section 515(b)(24) of SMCRA.430 In addition, there is no legal, technical, or scientific reason why designs for restored stream channels should be subject to less rigorous certification standards than designs for streamchannel diversions. Proposed paragraph (c)(2)(v)(A) would require that designs for permanent stream-channel diversions, temporary stream-channel diversions that will be in use for 2 or more years, U.S.C. 1265(b)(3).

This provision is similar to the last sentence of existing 30 CFR 816.43(a)(3), with a few exceptions. First, the existing rule applies only to permanent stream-channel diversions. Applying the design requirements of proposed paragraph (c)(2)(v)(A) to temporary stream-channel diversions that will be in use for 2 or more years would reduce the damage to aquatic resources caused by temporary diversions that remain in use for extended periods, consistent with the requirement in section 515(b)(24) of SMCRA 431 to minimize adverse impacts on fish, wildlife, and related environmental values to the extent possible, using the best technology currently available. In recognition of the shorter lifespan of temporary diversions, we propose to specify that, for temporary stream-channel diversions that will remain in use for 2 or more years, the vegetation proposed for planting in the riparian zone need not include species that would not reach maturity until after the diversion is removed. In other words, faster-growing species like willows, alders, and poplars or early successional natural riparian vegetation would be acceptable. Second, proposed paragraph (c)(2)(v)(A) would specify that the premining characteristics of the original stream channel include, but are not limited to, the baseline stream pattern, profile, dimensions, substrate, habitat, and natural vegetation growing in the riparian zone. The addition of this clarification is intended to make our regulations more consistent with similar requirements under section 404 of the Clean Water Act and its implementing regulations. It also would minimize adverse impacts on fish, wildlife, and related environmental values to the extent possible, using the best technology currently available, as required by section 515(b)(24) of SMCRA.432 Third, proposed paragraph (c)(2)(v)(A) would specify that the design must minimize adverse alteration of stream channels on and off the site, including channel deepening or enlargement.

Proposed paragraph (c)(2)(v)(B) would require that the stream-channel design ensure that the hydraulic capacity of all temporary and permanent streamchannel diversions is at least equal to the hydraulic capacity of the unmodified stream channel immediately upstream from the diversion and no greater than the hydraulic capacity of the unmodified stream channel immediately downstream from the diversion. Existing 30 CFR 816.43(b)(2) applies the same standard for the hydraulic capacity of the diversion both upstream and downstream of the diversion; i.e., the designed hydraulic capacity of the diversion must be at least equal to the hydraulic capacity of the unmodified stream channel immediately upstream and downstream from the diversion. Our proposal to require that the designed hydraulic capacity of the diversion be no greater than (rather than at least equal to) the hydraulic capacity of the unmodified stream channel immediately downstream from the diversion would protect against the scouring and other adverse impacts that could result from a sudden constriction in channel capacity if the diversion was allowed to exceed the capacity of the unmodified stream channel downstream of the diversion. Therefore, proposed paragraph (c)(2)(v)(B) would be consistent with the requirement in section 515(b)(24) of SMCRA 434 to minimize adverse impacts on fish, wildlife, and related environmental values to the extent possible, using the best technology currently available. Proposed paragraph (c)(2)(v)(C) would require that all temporary and permanent stream-channel diversions be designed so that the combination of channel, bank, and flood-plain configuration is adequate to pass safely the peak runoff of a 10-year, 6-hour precipitation event for a temporary diversion and a 100-year, 6-hour precipitation event for a permanent diversion. Proposed paragraph (c)(2)(v)(C) is substantively identical to existing 30 CFR 816.43(b)(3). We invite comment on whether the design event for a temporary diversion should be 433 Id. 434 Id. VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 raised to the 25-year, 6-hour event to provide added safety and protection against overtopping. Proposed paragraph (c)(2)(vi) would require submission of a certification from a qualified registered professional engineer that the designs for all streamchannel diversions and all stream channels to be restored after the completion of mining meet the design requirements of 30 CFR 780.28 and any additional design criteria established by the regulatory authority. Our proposed rule differs from the design certification elements of existing 30 CFR 816.43(b)(4) in that we propose to expand the design certification requirement to apply to all stream channels to be restored after the completion of mining, not just to stream-channel diversions as in the existing rule. As discussed above, there is no legal, technical, or scientific reason to apply less rigorous design and certification requirements to restored stream channels than to permanent stream-channel diversions. In addition, we propose to require that the engineer certify that the design meets the design requirements of 30 CFR 780.28, not the performance standards as in the existing rule, because performance standards do not apply directly to designs. Finally, we propose to specify that the certification may be limited to the location, dimensions, and physical characteristics of the stream channel; it need not include restoration of ecological function, which may be beyond the professional competency of an engineer. Proposed Paragraph (d): What requirements apply to an application to construct an excess spoil fill or coal mine waste disposal facility in a perennial or intermittent streams? Proposed paragraph (d)(1) would apply the requirements of proposed paragraph (d)(2) in place of the requirements of proposed paragraph (b)(2) if the applicant proposes to construct an excess spoil fill or coal mine waste disposal facility that would encroach upon any part of a perennial or intermittent stream. We are proposing paragraph (d) because we recognize that some of the requirements of proposed paragraph (b)(2) that would apply to activities in streams cannot be met with respect to a stream segment that is buried underneath an excess spoil fill or a coal mine waste disposal facility. A permit application that contains a proposal to construct an excess spoil fill or a coal mine waste disposal facility that would not encroach upon any part of a perennial or intermittent stream would not be subject to the requirements of proposed paragraph PO 00000 Frm 00083 Fmt 4701 Sfmt 4702 44517 (d)(2). However, if the proposed fill or disposal facility would disturb the surface of land within 100 feet of a perennial or intermittent stream,435 the application would have to comply with the requirements of proposed paragraph (b)(2). Proposed paragraph (d)(2) would identify the demonstrations that a permit application must include if the applicant proposes to construct an excess spoil fill or coal mine waste disposal facility in a perennial or intermittent stream. The legal authority for the proposed demonstration requirements is set forth in detail in the introductory paragraphs of the discussion of proposed 30 CFR 780.28 in this preamble and will not be repeated here. The demonstrations that we propose to require are a combination of other regulatory program and Clean Water Act requirements; measures that constitute the best technology currently available to minimize any adverse impacts on fish, wildlife, and related environmental values, as required by section 515(b)(24) of SMCRA; 436 and fish and wildlife enhancement measures intended to offset any unavoidable longterm damage to fish, wildlife, and related environmental values. Proposed paragraph (d)(2)(i) would require that the applicant demonstrate that the operation has been designed to minimize the amount of excess spoil or coal mine waste generated, which would have the effect of minimizing the need for or the size of the excess spoil fill or coal mine waste disposal facility. This finding corresponds to proposed 30 CFR 780.35(b) for excess spoil. For coal mine waste, this finding in essence would require a description of the steps taken to minimize the amount of coal mine waste generated by the coal preparation process, such as the use of filter presses, or an explanation of why minimization measures are not practicable. Proposed paragraph (d)(2)(ii) would require that the applicant demonstrate that, after evaluating all potential upland locations in the vicinity of the proposed operation, there is no practicable alternative that would avoid placement of excess spoil or coal mine waste in a perennial or intermittent stream. Potential upland locations that must be considered include, but are not limited to, abandoned mine lands and existing fills with excess capacity. The application must identify potential locations such as the examples 435 See the discussion of proposed 30 CFR 780.16(c) in this preamble for an explanation of how this distance must be measured. 436 Id.

We anticipate that, for excess spoil, the permit applicant and regulatory authority would conduct this analysis in a manner similar to that described in Kentucky Reclamation Advisory Memorandum (RAM) 145, which establishes a fill placement optimization process for steep-slope mining in Kentucky.437 For coal mine waste, the application would have to explain why an alternative configuration, location, or coal mine waste disposal method is not practicable. Proposed paragraph (d)(2)(iii) would require that the applicant demonstrate that, to the extent possible using the best technology currently available, the proposed excess spoil fill or coal mine waste disposal facility has been designed to minimize both placement of excess spoil or coal mine waste in a perennial or intermittent stream and adverse impacts on fish, wildlife, and related environmental values. This provision corresponds in part to the fill optimization requirements of proposed 30 CFR 780.35(c). We anticipate that the RAM 145 process mentioned above may assist in meeting this requirement. Proposed paragraph (d)(2)(iii) would implement, in part, section 515(b)(24) of SMCRA,438 which provides that surface coal mining and reclamation operations must be conducted to minimize disturbances and adverse impacts on fish, wildlife, and related environmental values to the extent possible, using the best technology currently available. Proposed paragraph (d)(2)(iv) would require that the applicant demonstrate that the fish and wildlife enhancement plan for the proposed operation includes measures that would fully and permanently offset any long-term adverse impacts that the fill, refuse pile, or coal mine waste impoundment would have on fish, wildlife, and related environmental values within the footprint of the fill, refuse pile, or coal mine waste impoundment. The regulatory authority would determine the meaning of ‘‘fully and permanently offset’’ on a case-by-case basis. At a minimum, riparian corridors must be protected by conservation easements (dedicated to an appropriate agency or organization) or deed restrictions so that the newly planted vegetation is not destroyed after bond release. We invite comment on whether the final rule could or should include more specific 437 Kentucky Energy and Environment Cabinet, Department for Natural Resources, Reclamation Advisory Memorandum # 145 (December 16, 2009).

We encourage submission of data to document the success or failure of those measures. Proposed paragraph (d)(2)(v) would require that the applicant demonstrate that the excess spoil fill or coal mine waste disposal facility has been designed in a manner that will not cause or contribute to a violation of water quality standards or result in the formation of toxic mine drainage. The demonstration that this paragraph would require is intended to ensure the proposed operation will not cause material damage to the hydrologic balance outside the permit area. In particular, it is intended to ensure that discharges to surface water or groundwater from the excess spoil fill or coal mine waste disposal facility would not have a substantial adverse impact on water quality or aquatic biota in receiving streams. As defined in 30 CFR 701.5, toxic mine drainage means any discharge that ‘‘contains a substance that through chemical or physical effects is likely to kill, injure, or impair biota commonly present in that area that might be exposed to it.’’ Proposed paragraph (d)(2)(vi) would require that the applicant demonstrate that the revegetation plan submitted under proposed 30 CFR 780.12(g) requires reforestation of a completed excess spoil fill if the land is forested at the time of application or if it would revert to forest under conditions of natural succession. This measure is intended to minimize the adverse impacts of the fill on watershed hydrology, especially the quantity and quality of surface runoff, and aquatic life in the stream. Proposed Paragraph (e): What are the regulatory authority’s responsibilities? Proposed paragraph (e)(1)(i) would require that the regulatory authority establish objective standards for determining when the ecological function of a restored or permanentlydiverted perennial or intermittent stream has been restored. Objective standards are essential to fair enforcement of the requirement for restoration of the ecological function of streams and to enable permit applicants to develop appropriate and comprehensive reclamation plans. Proposed paragraph (e)(1)(ii) would PO 00000 439 33 U.S.C. 1344. Frm 00084 Fmt 4701 require that, in establishing these standards, the regulatory authority coordinate with the Clean Water Act permitting authority to ensure compliance with all Clean Water Act requirements. Proposed paragraph (e)(1)(iii) would specify that the standards established by the regulatory authority must comply with the functional restoration requirements of proposed 30 CFR 816.57(b)(2). In relevant part, proposed 30 CFR 816.57(b)(2) would require that a stream flowing through a restored stream channel or stream-channel diversion have a biological condition adequate to support the designated uses of the original stream segment under section 101(a) or 303(c) of the Clean Water Act 440 before mining. This provision may allow limited changes in the species composition of the array of insects, fish, and other aquatic organisms found in a stream flowing through a restored stream channel or stream-channel diversion, as long as the changes do not preclude existing uses or attainment of designated uses. Proposed 30 CFR 816.57(b)(2) also would require that the biological condition of the restored stream be determined using a protocol that meets the requirements of proposed 30 CFR 780.19(e)(2) and that populations of organisms used to determine the postmining biological condition of the stream segment be selfsustaining within that segment. We propose to include this provision because the presence of individual organisms that happen to drift into the reconstructed channel from other areas is not an indicator of restoration of the ecological function of the restored stream segment. Proposed paragraph (e)(2) specifies that the regulatory authority may not approve an application that includes any activities included in proposed paragraph (a)(1) unless the regulatory authority first makes a written finding that the applicant has fully satisfied all applicable requirements of 30 CFR 780.28. It also would require that the finding be accompanied by a detailed explanation and rationale for the finding. These requirements are appropriate, given the purposes and provisions of SMCRA discussed in the introductory paragraphs of the preamble to 30 CFR 816.57 and the typically high value of perennial and intermittent streams to fish and wildlife. 440 33 Sfmt 4702 E:\FR\FM\27JYP2.SGM U.S.C. 1251(a) and 1313(c). 27JYP2 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules tkelley on DSK3SPTVN1PROD with PROPOSALS2 15. Section 780.29: What information must I include in the surface-water runoff control plan? We propose to revise this section to require that each application include a surface-water runoff control plan. We propose to require this plan because uncontrolled surface-water runoff can and has been known to cause flooding downgradient of the operation, which in turn can result in material damage to the hydrologic balance outside the permit area, property damage, and loss of human life, as well as adverse impacts on fish, wildlife, and related environmental values. Section 510(b)(3) of SMCRA 441 provides that the regulatory authority may not approve a permit application unless the application affirmatively demonstrates and the regulatory authority finds in writing that the proposed operation has been designed to prevent material damage to the hydrologic balance outside the permit area. Section 515(b)(24) of SMCRA 442 requires that surface coal mining and reclamation operations minimize adverse impacts on fish, wildlife, and related environmental values. Proposed paragraph (a)(1) specifies that the plan must explain how surfacewater runoff will be handled in a manner that will prevent peak discharges from the proposed permit area, both during and after mining and reclamation, from exceeding premining peak discharges from the same area for the same-size precipitation event. Proposed paragraph (a)(1) also requires use of the appropriate regional NRCS synthetic storm distribution to estimate peak discharges. Design criteria for hydraulic structures intended to handle overland flow from precipitation events are based in part on the peak runoff rate and/or runoff volume from the area draining to the structure. Actual precipitation records for small drainage areas generally are not available, so engineers typically rely upon mathematical models instead. The distribution of rainfall intensities is one of the primary inputs to those models. We propose to require use of the appropriate regional NRCS synthetic storm distribution to determine runoff intensities and peak flows because it is a widely accepted, prudent engineering design methodology. Maximum runoff from a drainage area occurs when the peak intensity of the rainfall event coincides with the time of concentration (the length of time between the beginning of the rainfall 441 30 U.S.C. 1260(b)(3). 442 30 U.S.C. 1265(b)(24). VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 event and the time when runoff from the entire drainage area first arrives at the outlet for the drainage area). Typically, for precipitation events with the same return interval (2 years, 10 years, 100 years, etc.), peak intensity is much greater for storms of short duration—the shorter the duration, the greater the maximum intensity and the greater the amount of peak flow from surface runoff. Traditionally, peak stormwater runoff from a drainage area was determined using a storm duration approximately 1.7 times greater than the time of concentration. Use of the NRCS synthetic storm distribution accomplishes this determination automatically. For example, precipitation intensity during the 1-hour or 6-hour increment with the highest rainfall amount within the 24-hour 10year synthetic distribution (theoretical storm event) is identical to precipitation intensity and total rainfall during traditional 1-hour and 6-hour 10-year events. Therefore, it is not necessary to select a storm duration related to the time of concentration to capture the greater intensities of events of shorter duration. Proposed paragraph (a)(2) specifies that the explanation in paragraph (a)(1) must consider the findings in the PHC determination prepared under § 780.20. Proposed paragraph (b) would require that the plan include a surface-water runoff monitoring and inspection program that would provide sufficient precipitation and stormwater discharge data for the proposed permit area to evaluate the effectiveness of surfacewater runoff control practices. The surface-water runoff monitoring and inspection program must specify criteria for monitoring, inspection, and reporting consistent with 30 CFR 816.34(d), which contains the corresponding performance standards. The program must contain a monitoring point density that adequately represents the drainage pattern and drainage distribution across the entire proposed permit area, with a minimum of one monitoring point for each watershed discharge point. We invite comment on whether the proposed minimum monitoring point density standard is too high or too low. Proposed paragraph (c) would require that the permit application include descriptions, maps, and cross-sections of all runoff control structures, including diversions and other channels used to collect and convey surface-water runoff. Existing 30 CFR 780.29 applies this requirement only to diversions, which, under 30 CFR 816.43, could be construed as excluding channels constructed to collect and convey PO 00000 Frm 00085 Fmt 4701 Sfmt 4702 44519 surface runoff from the area to be disturbed by the mining operations. Under proposed paragraph (c), all such channels would have to be designed in accordance with the standards in 30 CFR 816.43. Proposed paragraph (c) is intended to ensure that these channels are safe, stable, and of adequate capacity. 16. Section 780.35: What information must I provide concerning the minimization and disposal of excess spoil? We propose to revise, reorganize, and expand our existing rules governing permitting requirements for the disposal of excess spoil. Background and Rationale for the Proposed Rule Changes Disposal of excess spoil and coal mine waste often involves the filling of substantial portions of stream valleys, especially in central Appalachia. Based upon our regulatory experience, updated science, and modern engineering practices, we propose to revise our regulations to minimize the creation of excess spoil and to ensure that excess spoil fills and coal mine waste disposal facilities are located and designed to minimize disturbances and adverse impacts on fish, wildlife, and related environmental values to the extent possible, using the best technology currently available, as required by sections 515(b)(24) and 516(b)(11) of SMCRA.443 Our existing regulations pertaining to the disposal of excess spoil primarily focus on ensuring that fills are safe and stable. We propose to add several requirements intended to promote environmental protection, including minimization of the adverse environmental impacts of fill construction in perennial and intermittent streams. We recognize that section 515(b)(22) of SMCRA,444 which establishes standards for the disposal of excess spoil, does not include any requirements specifically oriented toward environmental protection, but instead focuses on engineering standards intended to promote stability, prevent mass movement, and control infiltration of water. However, section 515(b)(24) of SMCRA 445 does require that surface coal mining and reclamation operations be conducted in a manner that minimizes disturbances to, and adverse impacts on, fish, wildlife, and related environmental values to the extent possible, using the 443 30 U.S.C. 1265(b)(24) and 1266(b)(11). U.S.C. 1265(b)(22). 445 30 U.S.C. 1265(b)(24). 444 30 E:\FR\FM\27JYP2.SGM 27JYP2 tkelley on DSK3SPTVN1PROD with PROPOSALS2 44520 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules best technology currently available. Section 515(b)(24) 446 applies to the disposal of excess spoil both by its own terms (disposal of excess spoil is a part of surface coal mining and reclamation operations) and through section 515(b)(22)(I),447 which requires that the placement of excess spoil meet ‘‘all other provisions of this Act.’’ SMCRA contains numerous environmental protection requirements that apply to all surface coal mining and reclamation operations and all aspects of those operations, including the disposal of excess spoil. The fact that section 515(b)(22) 448 does not mention environmental protection in no way suggests that excess spoil fills need not comply with the environmental protection provisions of SMCRA or that we lack the authority to adopt regulations establishing environmental protection requirements for those structures. The goal of the excess spoil minimization and fill size optimization requirements of proposed paragraphs (b) and (c) is to minimize fill footprints and thus minimize disturbances of forests, perennial and intermittent streams, and riparian vegetation, consistent with the requirement in sections 515(b)(24) and 516(b)(11) of SMCRA 449 to minimize disturbances and adverse impacts on fish, wildlife, and related environmental values to the extent possible using the best technology currently available. As part of our oversight activities, we conducted studies in 1999 in Kentucky, Virginia, and West Virginia to determine how state regulatory authorities were administering SMCRA regulatory programs regarding restoration of approximate original contour. From our review of permit files and reclaimed mines, we determined that, typically, some of the spoil placed in excess spoil fills could have been retained on or returned to mined-out areas. See ‘‘An Evaluation of Approximate Original Contour and Postmining Land Use in Kentucky’’ (OSMRE, September 1999); ‘‘An Evaluation of Approximate Original Contour Variances and Postmining Land Uses in Virginia’’ (OSMRE, September 1999); and ‘‘Final Report: An Evaluation of Approximate Original Contour and Postmining Land Use in West Virginia’’ (OSMRE, May 1999). In many instances, we found that the permit application overestimated the anticipated volume of excess spoil that the operation would produce. In 446 Id. 447 30 U.S.C. 1265(b)(22)(I). U.S.C. 1265(b)(22). 449 30 U.S.C. 1265(b)(24) and 1266(b)(11). 448 30 VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 addition, fills were designed and constructed larger than necessary to accommodate the anticipated excess spoil, which resulted in the unnecessary disturbance of additional land. Kentucky, Virginia, and West Virginia worked with us to develop enhanced guidance on material balance determinations, spoil management, and approximate original contour determinations to correct these problems to the extent feasible under the existing regulations. The regulatory authorities in those states have adopted policies based on that guidance for use in reviewing permit applications.450 We also developed guidance for use under the Tennessee federal regulatory program.451 If adopted, the rule that we are proposing today would provide further authority for the policies in place in Kentucky, Tennessee, Virginia, and West Virginia. It would strengthen the enforceability of decisions based on those policies and provide national consistency by ensuring that certain basic requirements will be applied nationwide, including in those states that have not adopted such policies. The environment, the public, and the regulated community are best served by the adoption of national regulations to clarify environmental considerations concerning the generation and disposal of excess spoil. Proposed Paragraph (a): Applicability. This proposed paragraph would clarify that the provisions of 30 CFR 780.35 apply only to permit applications that propose to generate excess spoil. Proposed Paragraph (b): Demonstration of Minimization of Excess Spoil Proposed paragraph (b)(1) would require a demonstration, with supporting calculations and other documentation, that the operation has been designed to minimize, to the extent possible, the volume of excess spoil that the operation will generate. Designing the operation in this fashion should ensure that the maximum amount of overburden is returned to the mined-out area. Our goal is to ensure that the volume of overburden placed in excess spoil fills is minimized to the maximum extent possible. Minimizing the volume of overburden placed in excess spoil 450 Kentucky Department of Natural Resources Reclamation Advisory Memorandum No. 145 (2009), Virginia Department of Mines, Minerals and Energy Guidance Memorandum 4–02 (2002), West Virginia Department of Environmental Protection Final Approximate Original Contour Document Guidance Policy (‘‘AOC+’’) (1999). 451 OSMRE Knoxville Field Office Engineering Procedure 2.1: Steep Slope Mining: AOC and Excess Spoil Determination (2001). PO 00000 Frm 00086 Fmt 4701 Sfmt 4702 fills is critical to minimizing the amount of undisturbed land affected by fill construction and to ensuring that those fills bury or otherwise impact the shortest length of stream possible. Proposed paragraph (b)(2) would specify the factors that the permit applicant and the regulatory authority must consider in determining whether the proposed operation has been designed to minimize the creation of excess spoil to the extent possible. It requires consideration of safety and stability needs and requirements; revegetation and postmining land use needs and requirements; the need for drainage structures, access roads, and berms; applicable regulations concerning backfilling, compaction, grading, and restoration of the approximate original contour; and other relevant regulatory requirements, in particular those pertaining to protection of water quality and fish, wildlife, and related environmental values. Some or all of those factors may limit the amount of spoil that can be returned to the mined-out area, especially the requirements related to safety, stability, and postmining land use. Also, if the regulatory authority does not approve the proposed postmining land use, the applicant and the regulatory authority would need to revisit the demonstration to determine whether it must be revised to reflect the needs and attributes of the postmining land use that is finally approved. In addition, proposed paragraph (b)(2)(iii) would specify that drainage structures, access roads, and berms on the perimeter of the backfilled area must not exceed a total width of 20 feet unless the permit applicant can demonstrate a need for a greater width. This restriction would maximize placement of overburden material on the mined-out area and minimize the generation and placement of excess spoil. In many cases, construction of access roads or drainage controls wider or larger than necessary prevents maximum spoil placement within the mined-out area, thus creating larger excess spoil fills and burial of a greater length of perennial or intermittent stream segments than absolutely necessary. We propose to select 20 feet as the maximum width because that is the typical width of a drainage bench on the face of a fill or embankment. Twenty feet should provide adequate room for drainage and sediment controls during the period between final grading and establishment of vegetation. Twenty feet also would afford adequate access for equipment in the event that maintenance is required before final bond release. We seek comment on E:\FR\FM\27JYP2.SGM 27JYP2 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules whether the maximum width should be larger or smaller than 20 feet. To attain the goal of minimizing both the amount of land disturbed and the length of perennial and intermittent stream segments buried or otherwise adversely affected, proposed paragraph (b)(3) would clarify that premining elevations do not operate as a cap on the elevation of backfilled areas. Instead, the final elevation would be determined on the basis of the factors listed in proposed 30 CFR 780.35(b)(2), together with the requirement that the final surface configuration be compatible with the surrounding terrain and be consistent with natural premining landforms. For the same reason, proposed paragraph (b)(4) would prohibit the creation of a final-cut impoundment under 30 CFR 816.49(b) or the placement of coal combustion residues or noncoal materials in the mine excavation if doing so would displace spoil removed from the excavation to the extent that the displaced mine spoil would have to be placed in an excess spoil fill. tkelley on DSK3SPTVN1PROD with PROPOSALS2 Proposed Paragraph (c): Fill Capacity Demonstration Proposed paragraph (c) would require that the application include a demonstration, with supporting calculations and other documentation, that the designed maximum cumulative volume of all proposed excess spoil fills within the permit area is no larger than the capacity needed to accommodate the anticipated cumulative volume of excess spoil that the operation will generate, as calculated under paragraph (b). This requirement is intended to prohibit the practice of designing an operation with a larger number and greater size of excess spoil fills than necessary and then constructing only part of each fill. This practice results in the filling of a greater length of stream than would be necessary if each fill was used to its maximum capacity, especially when using a bottom-up method of fill construction in which the entire footprint of the fill is disturbed either before or shortly after initial placement of excess spoil in the fill. Adoption of proposed paragraph (c) would minimize the adverse impacts of the operation on fish, wildlife, and related environmental values, as required by section 515(b)(24) of SMCRA,452 by minimizing the amount of land and water disturbed to construct excess spoil fills. 452 30 U.S.C. 1265(b)(24). VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 Proposed Paragraph (d): Requirements Related to Perennial and Intermittent Streams Proposed paragraph (d) would specify that a permit applicant proposing to construct an excess spoil fill in or within 100 feet of a perennial or intermittent stream 453 must comply with the requirements of proposed 30 CFR 780.28 concerning activities in or near perennial or intermittent streams. Proposed Paragraph (e): Location Proposed paragraph (e)(1) would require that a permit applicant submit maps and cross-section drawings or models showing the location and profile of all proposed excess spoil fills. This requirement corresponds to the first sentence of existing paragraph (a), which we propose to modernize to allow the use of models at the discretion of the permit applicant and the regulatory authority. Models can be more detailed than either maps or crosssections. We also propose to require that the application include a profile of each excess spoil fill so that the regulatory authority is able to determine whether the completed fill would meet all applicable surface configuration requirements. Proposed paragraph (e)(2) would specify that fills must be located on the most moderately sloping and naturally stable areas available. It also would specify that the regulatory authority will determine which areas are available for excess spoil fill construction after considering other requirements of the Act and the regulatory program. This paragraph corresponds to part of existing 30 CFR 816.71(c), which we propose to move to 30 CFR 780.35 because it is a permitting requirement, not a performance standard. We propose to add the provision specifying that the regulatory authority will determine which areas are available for excess spoil fill construction to improve consistency with section 515(b)(22)(E) of SMCRA,454 which requires that excess spoil be placed ‘‘upon the most moderate slope among those upon which, in the judgment of the regulatory authority, the spoil could be placed in compliance with all the requirements of the Act.’’ Because one of the requirements of the Act is the provision in section 515(b)(24) 455 specifying that surface coal mining and reclamation operations must be conducted so as to minimize disturbances and adverse 453 See the discussion of proposed 30 CFR 780.16(c) in this preamble for an explanation of how this distance must be measured. 454 30 U.S.C. 1265(b)(22)(E). 455 30 U.S.C. 1265(b)(24).

In other words, the requirement to place excess spoil on the most moderate slope is subordinate to compliance with other requirements of the Act and regulatory program. Proposed paragraph (e)(3) provides that, whenever possible, the permit applicant must place fills on or above a natural terrace, bench, or berm if that location would provide additional stability and prevent mass movement. This paragraph corresponds to the remainder of existing 30 CFR 816.71(c), which we propose to move to 30 CFR 780.35 because it is a permitting requirement, not a performance standard. Proposed paragraph (e)(3) is consistent with section 515(b)(22)(E) of SMCRA,456 which requires that excess spoil be placed ‘‘where possible, upon, or above, a natural terrace, bench, or berm, if such placement provides additional stability and prevents mass movement.’’ However, spoil placement upon or above a natural terrace, bench, or berm may not always be possible because section 515(b)(24) of SMCRA 457 provides that surface coal mining and reclamation operations must minimize disturbances and adverse impacts on fish, wildlife, and related environmental values to the extent possible, using the best technology currently available. Implementation of that requirement may entail placement of spoil in a location other than on or above a natural terrace, bench, or berm, provided the alternative location is stable and would have lesser overall adverse impacts on fish, wildlife, and related environmental values. Proposed Paragraph (f): Design Plans Proposed paragraph (f) requires that an application for an operation that would generate excess spoil include detailed design plans for each excess spoil fill, prepared in accordance with the requirements of proposed 30 CFR 780.35 and 816.71 through 816.74. Proposed paragraph (f) corresponds to the portion of existing 30 CFR 780.35(a) that requires that the design comply with 30 CFR 816.71 through 816.74. For 456 30 457 30 E:\FR\FM\27JYP2.SGM U.S.C. 1265(b)(22)(E). U.S.C. 1265(b)(24). 27JYP2 44522 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules tkelley on DSK3SPTVN1PROD with PROPOSALS2 clarity and completeness, we propose to add language also requiring compliance with the requirements of 30 CFR 780.35, although those design requirements would apply anyway in the absence of this provision. Proposed paragraph (f) also would require that the applicant design the fill and appurtenant structures using current prudent engineering practices and any additional design criteria established by the regulatory authority. That requirement appears in the first sentence of existing 30 CFR 816.71(b)(1), which we propose to move to 30 CFR 780.35 because it is a design requirement, not a performance standard. Proposed Paragraph (g): Geotechnical Investigation Proposed paragraph (g) would require that the application include the results of a geotechnical investigation, with supporting calculations and analyses, of the site of each proposed excess spoil fill, with the exception of those sites at which spoil will be placed only on a preexisting bench under 30 CFR 816.74. This provision corresponds to existing paragraph (b). We propose to add a requirement that the applicant submit supporting calculations and analyses with the geotechnical investigation of the site of each proposed excess spoil fill. The additional data is essential for the permit application reviewer to determine the stability of the proposed design. Proposed paragraphs (g)(1) through (6) identify information that would have to be submitted with the application to document the geotechnical investigation and its results. Proposed paragraph (g)(1) would require sufficient foundation investigations, as well as any necessary laboratory testing of foundation material, to determine the design requirements for foundation stability for the site of each fill. This requirement currently appears in existing 30 CFR 816.71(d)(1). We propose to move it to 30 CFR 780.35(g) consistent with our effort to consolidate design requirements in the permitting rules rather than splitting them between the permitting rules and the performance standards. The foundation investigation is an element of the geotechnical investigation that is required for approval of a proposed excess spoil fill in a permit application. Proposed paragraphs (g)(2) through (6) correspond to, and are substantively identical to, existing paragraphs (b)(1) through (5), except as discussed below. We propose to revise paragraph (g)(3) to require that the applicant provide the VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 geographic coordinates and a narrative description, rather than just a survey, of all springs, seepage, mine discharges, and groundwater flow observed or anticipated during wet periods in the area of the proposed fill. The added precision will assist the regulatory authority in evaluating the adequacy of the excess spoil fill design. Proposed paragraph (g)(4) would require that the applicant provide an analysis of the potential effects of any underground mine workings within the proposed permit and adjacent areas, including the effects of any subsidence that may occur as a result of previous, existing, and future underground mining operations. The proposed requirement is similar to the portion of existing 30 CFR 816.71(d)(1) that requires that the analyses of foundation conditions take into consideration the effect of underground mine workings, if any, upon the stability of the fill and appurtenant structures. Existing 30 CFR 780.35(b)(3) also requires a survey of the potential effects of subsidence that may occur as a result of past and future underground mining operations. Our proposed revisions would require that the analysis also consider the potential effects of subsidence from existing underground mining operations, not just past and future operations. The design needs to be capable of withstanding all potential impacts of any subsidence that may occur during the life of the proposed structure. We propose to add the reference to the proposed permit and adjacent areas to ensure that the analysis includes all operations that have the potential to cause subsidence that may affect the proposed fill, not just operations within the proposed permit area. Proposed paragraph (g)(6) is substantively identical to existing paragraph (b)(5), with the exception that we propose to revise this paragraph to clarify that the stability analyses that it requires must address static, seismic, and post-earthquake (liquefaction) conditions because those conditions are all part of a comprehensive stability analysis. Proposed Paragraph (h): Operation and Reclamation Plans Proposed paragraph (h) would require that the permit applicant submit plans for the construction, operation, maintenance, and reclamation of all excess spoil fills in accordance with the requirements of §§ 816.71 through 816.74. This requirement corresponds to a similar provision in existing paragraph (a). However, that provision includes a requirement for plans for the ‘‘removal, if appropriate, of the site and PO 00000 Frm 00088 Fmt 4701 Sfmt 4702 structures.’’ Because excess spoil fills are permanent, it is not appropriate to include plans for their removal in the application. Consequently, we propose to replace the requirement for plans for removal of the fills with a requirement for plans for their reclamation, which would consist of final site preparation and revegetation consistent with the approved postmining land use. Proposed Paragraph (i): Additional Requirements for Bench Cuts or RockToe Buttresses Proposed paragraph (i) combines overlapping requirements in existing paragraph (c) and 30 CFR 816.71(d)(2) concerning application and design requirements for bench cuts or rock-toe buttresses. We propose to revise the existing requirements by replacing the term ‘‘keyway cuts’’ with ‘‘bench cuts.’’ The term ‘‘keyway cut’’ is technically a cut beneath a dam that is used to extend low-permeability fill material to, but not into, bedrock. The term ‘‘bench cut’’ is more appropriate here because it refers to cuts into bedrock, not just down to bedrock, which is essential in the context of fill construction under steepslope conditions. Proposed Paragraph (j): Design Certification Proposed paragraph (j) would require that the application include a certification by a qualified registered professional engineer experienced in the design of earth and rock fills that the design of all fills and appurtenant structures meets the requirements of 30 CFR 780.35. This requirement currently appears in the second sentence of existing 30 CFR 816.71(b)(1), which we propose to move to 30 CFR 780.35 consistent with our effort to consolidate design requirements in the permitting rules rather than splitting them between the permitting rules and the performance standards. We propose no substantive changes to this provision. 17. Section 780.37: What information must I provide concerning access and haul roads? We propose to revise and reorganize existing paragraphs (a)(1), (2), (3), and (5) into proposed paragraphs (a)(1) and (2) to improve clarity and to eliminate redundancies and unnecessary crossreferences. Proposed paragraph (a)(3) would require that the applicant demonstrate how all proposed roads will comply with the applicable requirements of 30 CFR 780.28 (activities in, through, or near streams), 816.150 (general performance standards for roads), and 816.151 (performance standards for primary roads). Section E:\FR\FM\27JYP2.SGM 27JYP2 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules mining regulations with references to the corresponding underground mining regulations, and changes of a similar nature. Our proposed revisions to part 783 are similarly substantively identical to the corresponding revision that we propose in part 779. Therefore, this portion of the preamble discusses only those proposed revisions to part 783 that differ from the proposed revisions to the corresponding provisions of part 779. Otherwise, the rationale that we provide for the proposed revisions to part 779 applies with equal effect to our proposed revisions to part 783. We also call attention to our proposed revisions to the definition of ‘‘adjacent area’’ in 30 CFR 701.5, which clarifies the size and extent of the area to which certain of the information requirements of part 783 would apply. As revised, the definition would include all areas that could experience adverse impacts from either a surface coal mining operation or underground mining activities, including potential impacts from any subsidence that may occur as a result of underground mining activities. The existing definition is limited to areas that either would be adversely impacted or could reasonably be expected to be adversely impacted. If adopted as proposed, the revised definition would ensure the collection of baseline and other data from all areas where adverse impacts are possible, not just from those areas where adverse impacts are probable. In other words, our proposed definition of ‘‘adjacent area’’ would include, at a minimum, the entire area overlying the proposed underground workings plus the area within a reasonable angle of draw from the perimeter of those workings. H. Part 783: Underground Mining Permit Applications—Minimum Requirements for Information on Environmental Resources and Conditions tkelley on DSK3SPTVN1PROD with PROPOSALS2 780.28 is an element of the rule that we are proposing today, while 30 CFR 816.150 and 816.151 are existing rules. We propose to add paragraph (a)(4) to require that the application identify each road that would be located in or within 100 feet of the channel of a perennial or intermittent stream,458 each proposed ford of a perennial or intermittent stream that would be used as a temporary route during road construction, any plans to alter or relocate a natural stream channel, and each proposed low-water crossing of a perennial or intermittent stream channel. The regulatory authority would need this information to determine compliance with the applicable requirements of proposed 30 CFR 780.28 and existing 30 CFR 816.150, and 816.151. We also propose to add paragraph (a)(5) to require that the applicant explain why any proposed fords, alterations or relocations of natural stream channels, or low-water crossings are necessary and how they comply with the applicable requirements of proposed 30 CFR 780.28 and section 515(b)(18) of the Act.459 Section 515(b)(18) of SMCRA 460 provides that surface coal mining and reclamation operations must ‘‘refrain from the construction of roads or other access ways up a stream bed or drainage channel or in such proximity to such channel so as to seriously alter the normal flow of water.’’ The proposed revisions are needed to ensure that the stream protection requirements of proposed 30 CFR 780.28 are applied to roads, which can have very damaging environmental impacts on streams. 1. Section 783.24: What maps, plans, and cross-sections must I submit with my permit application? Part 783 contains the minimum requirements for information on environmental resources and environmental conditions when preparing applications for underground mining operations. It is the counterpart to part 779 for applications for surface mining operations. In general, part 783 is substantively identical to part 779, except for the substitution of ‘‘underground mining activities’’ for ‘‘surface mining activities,’’ the replacement of references to surface 458 See the discussion of proposed 30 CFR 780.16(c) in this preamble for an explanation of how this distance must be measured. 459 30 U.S.C. 1265(b)(18). 460 Id. VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 We propose to apply the requirements of 30 CFR 783.24(a)(5) to include the location of surface and subsurface manmade features within, passing through, or passing over the proposed permit and adjacent areas, rather than just the proposed permit area as in the corresponding proposed surface mining rules at 30 CFR 779.24(a)(5). The regulatory authority would need this information when evaluating the potential impacts of both the proposed underground mining operation and subsidence resulting from that operation on those features. Proposed 30 CFR 783.24(a)(11) would be the underground mining counterpart to proposed 30 CFR 779.24(a)(11), which, as previously discussed, would add a new provision requiring mapping PO 00000 Frm 00089 Fmt 4701 Sfmt 4702 44523 of all wellhead protection zones 461 located within one-half mile of the proposed permit area for surface mining operations. Proposed 30 CFR 783.24(a)(11) would expand that requirement to include all wellhead protection zones located within one-half mile of either the proposed permit area of an underground mine or the area overlying the proposed underground workings. This expansion is warranted to ensure that the permit application review process includes consideration of the potential impact of underground mining activities, and subsidence resulting from those activities, on these important zones and the water supplies that they protect. However, this provision is not intended to prohibit underground mining operations within wellhead protection zones when those operations can be conducted in a manner that will not endanger public water supplies or when the permit applicant can identify suitable alternative sources of water capable of providing water of equivalent quantity and quality. Proposed 30 CFR 783.24(a)(13) also would require that the map include the location of any discharge into or from an active, inactive, or abandoned underground or surface mine when the discharge is located within one-half mile of the area overlying the proposed underground workings, rather than just when the discharge is located within one-half mile of the proposed permit area as in our proposed surface mining rules at 30 CFR 779.24(a)(13). The larger area is appropriate because the permit area for an underground mine does not include the area overlying the underground workings unless the mine disturbs the surface of those lands. However, the regulatory authority needs the discharge information from the expanded area to fully evaluate the potential impacts of the proposed underground mining operation on the hydrologic balance and to prepare the CHIA. We propose to lift the suspension of existing 30 CFR 783.25(a)(3), (a)(8), and (a)(9) and remove those provisions from our rules. Our proposed actions are consistent with PSMRL I, Round II, in which the court remanded those provisions, which were then located at 30 CFR 783.25(c), (h), and (i), for further rulemaking proceedings because the preamble provided insufficient justification of the need for or usefulness of that information for 461 A wellhead protection zone or area is a surface and subsurface land area regulated under the Safe Drinking Water Act (42 U.S.C. 330f–300j) to prevent contamination of a well or well-field supplying a public water system. E:\FR\FM\27JYP2.SGM 27JYP2 tkelley on DSK3SPTVN1PROD with PROPOSALS2 44524 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules proposed underground mining operations.462 As discussed below in the context of 30 CFR 783.24(a)(21), (25), and (26), we are re-proposing those elements of the suspended rules that are relevant to underground mining operations and necessary or useful in the review of permit applications for underground mining operations. Proposed 30 CFR 783.24(a)(21) would require that the application include information concerning the nature, depth, thickness, and commonly used names of the coal seams to be mined. Except for the names of the coal seams, this information currently is part of suspended 30 CFR 783.25(a)(3). Information concerning the depth and thickness of the coal seam would assist the regulatory authority in reviewing the subsidence control plan. Chemical characteristics of the coal seam play an important role in determining whether acid mine drainage may be a problem. The name of the coal seam would allow the regulatory authority to compare reported data with data representative of that seam. The remaining information required by suspended 30 CFR 783.25(a)(3) either is not relevant to underground mining or is covered by the geologic information requirements in proposed 30 CFR 784.19(f), which corresponds to existing 30 CFR 784.22. Proposed 30 CFR 783.24(a)(23) would require that the application include a map and cross-sections showing the location and extent of known workings of active, inactive, or abandoned underground mines located either within the proposed permit area or within a 2,000-foot radius in any direction of the proposed underground workings. Existing 30 CFR 783.25(a)(5) applies this requirement to the permit and adjacent areas. The additional specificity in our proposed rule would ensure that the application contains location information for all other underground mine workings that could either impact or be impacted by the proposed operation. Proposed 30 CFR 783.24(a)(25), like suspended 30 CFR 783.25(a)(8), would require that the application include maps identifying the location and extent of existing or previously surface-mined areas within the proposed permit area. This information is important in determining which postmining surface configuration and revegetation success standards apply, as well as evaluating eligibility for the remining provisions of 30 CFR 785.25. Proposed 30 CFR 783.24(a)(26) closely resembles suspended 30 CFR 462 PSMRL I, Round II, 1980 U.S. Dist. LEXIS 17660 at *23–24 (D.D.C. 1980), 19 ERC (BNA) 1477. VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 783.24(a)(9). It would require that the application include a map with the location and dimensions of existing areas of spoil, coal mine waste, noncoal waste disposal sites, dams, embankments, other impoundments, and water treatment facilities within the proposed permit area. Those features would affect the reclamation plan, and possibly the operations plan, for the mine, so they should be included on the permit application maps. The proposed rule differs from the suspended rule in that the proposed rule does not include ‘‘waste,’’ which is an undefined term of uncertain meaning. The proposed rule uses updated terminology concerning coal mine waste and, for the reasons discussed in the part of this preamble that explains our proposed removal of existing 30 CFR 780.15, it does not include air pollution control facilities. Finally, proposed 30 CFR 783.24(a)(27), which corresponds to existing 30 CFR 783.25(a)(10), would expand the scope of the existing rule to include conventional gas and oil wells within both the proposed permit and adjacent areas, rather than just within the proposed permit area. As in the proposed surface mining counterpart rule at 30 CFR 779.24(a)(27), we also propose to require that the map include the extent of any directional or horizontal drilling for hydrocarbon extraction operations within both the proposed permit and adjacent areas. The permit area for an underground mine does not include the area overlying the underground workings or other areas where subsidence may occur. Therefore, the regulatory authority needs the information in proposed 30 CFR 783.24(a)(27) for both the proposed permit area and the adjacent area, not just the proposed permit area, when evaluating what impacts the proposed underground mining operation and any potential subsidence resulting from that operation may have on oil and gas operations. I. Part 784: Underground Mining Permit Applications—Minimum Requirements for Reclamation and Operation Plans Part 784 contains the minimum requirements for operation and reclamation plans when preparing applications for underground mining operations. It is the counterpart to part 780 for applications for surface mining operations. In general, part 784 is substantively identical to part 780, except for the substitution of ‘‘underground mining activities’’ for ‘‘surface mining activities,’’ the replacement of references to surface mining regulations with references to the corresponding underground mining PO 00000 Frm 00090 Fmt 4701 Sfmt 4702 regulations, and changes of a similar nature. Our proposed revisions to part 784 are similarly substantively identical to the corresponding revisions that we propose in part 780. Therefore, this portion of the preamble discusses only those proposed revisions to part 784 that differ from the proposed revisions to the corresponding provisions of part 780. Otherwise, the rationale that we provide for the proposed revisions to part 780 applies with equal effect to our proposed revisions to part 784. We also call attention to our proposed revisions to the definition of ‘‘adjacent area’’ in 30 CFR 701.5, which could significantly affect the scope of some of the plans that part 784 requires. As revised, the definition would include all areas that could experience adverse impacts from either a surface coal mining operation or underground mining activities, including potential impacts from any subsidence that may occur as a result of underground mining activities. At a minimum, this area would include the entire area overlying proposed underground workings plus the area encompassed by an appropriate angle of draw from the perimeter of those workings. It also would include all areas with underground mine pools that could be affected as well as areas that could be affected by any mine pool that forms after closure of the underground mine and any areas that could be affected by landslides or blowouts resulting from the formation of that mine pool. The existing definition is limited to areas that either would be adversely impacted or could reasonably be expected to be adversely impacted. If adopted as proposed, the revised definition would require that the reclamation plan address all areas where adverse impacts are possible, not just those areas where adverse impacts are probable. 1. Section 784.11: What must I include in the general description of my proposed operation? We propose to add language in paragraph (b)(5) to clarify that the narrative required by paragraph (b) must address underground mine ventilation boreholes, fans, and access roads. 2. Section 784.13: What additional maps and plans must I include in the reclamation plan? Proposed 30 CFR 784.13(a)(4), which would combine existing 30 CFR 784.23(b)(1) and (13), would require that the application include a map showing the location of all buildings, utility corridors, and other facilities to be used or constructed within the proposed E:\FR\FM\27JYP2.SGM 27JYP2 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules tkelley on DSK3SPTVN1PROD with PROPOSALS2 permit area, together with identification of each facility that will remain as a permanent feature after the completion of underground mining activities. We also propose to remove existing 30 CFR 784.23(b)(11), which requires a cross-section profile of the anticipated final surface configuration of the affected area, because this requirement duplicates part of proposed 30 CFR 784.12(d). The preamble to 30 CFR 780.13 includes a discussion of the proposed removal of existing 30 CFR 780.13(b)(7) concerning air pollution. There is no counterpart to existing 30 CFR 780.13(b)(7) in the underground mining regulations at 30 CFR 784.23, so the discussion of our proposed removal of that paragraph does not pertain to proposed 30 CFR 784.13. Paragraph numbering adjustments need to be made accordingly when applying the discussion in this preamble concerning 30 CFR 780.13 to 30 CFR 784.13. 3. Section 784.19: What baseline information on hydrology, geology, and aquatic biology must I provide? Proposed paragraph (a) differs from its counterpart in proposed 30 CFR 780.19(a) only in that it contains an additional requirement in paragraph (a)(5) that the baseline information collected be in sufficient detail to assist in preparing the subsidence control plan under 30 CFR 784.30. In the existing rules, this requirement appears in 30 CFR 784.22(a)(4) and applies only to geologic information. Proposed paragraph (c) is substantively identical to its counterpart in proposed 30 CFR 780.19(c) with the exception that we propose to add paragraph (c)(3)(D) to the surface-water quantity description. This new paragraph would require that the description include seepage-run sampling determinations, if the application proposes to deploy a longwall panel beneath a perennial or intermittent stream or employ other types of full-extraction mining methods beneath a perennial or intermittent stream. Seepage runs are a series of instream flow measurements taken to determine the discharge rate of the stream at various points. The measurement begins upstream of any probable impacts from the proposed underground mine, proceeds through the reach of the stream that lies above the proposed mine workings, and continues to a point in the stream downgradient of any probable impacts from the proposed mine. At each measurement point, the stream width is divided into segments and an average velocity is measured for each segment. VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 The average velocity is determined by either a single measurement taken at a point located six-tenths of the distance from the surface of the stream to the bottom of the stream or an average of two measurements taken at two-tenths and eight-tenths of the distance from the surface of the stream to the bottom of the stream. The discharge rate of each stream segment then is calculated based on the cross-sectional area and the average velocity. The sum of the discharge rates for all stream segments is the total streamflow at that point. Subsidence resulting from longwall mining can cause a loss of part or all of the streamflow. Where the overburden is sufficiently thick (>100 to 150 meters), streamflow may be diverted into dilated fractures in the rocks immediately underlying the stream. This is especially true for sandstone units which, when fractured, tend to remain open, allowing significant transmission of streamflow to groundwater. Groundwater flow through fractures behaves in a cubic-root function in that doubling of the size of a fracture aperture enables the fracture to transmit approximately eight times the original flow.463 The dilation of fractures caused by subsidence resulting from longwall mining can and frequently does result in diversion of surface streamflow into the groundwater via these fractures. Where this happens, the loss may be spatially limited; i.e., once the stream passes beyond the impact footprint of the mine, the flow generally returns to the surface at a level expected at that point based on areanormalized flow criteria (e.g., liters per minute per hectare drained). Seepage-run determinations are necessary to accurately determine the impacts of longwall mining on streamflow. Minor to moderate loss of streamflow often is not noticeable by visual observation. So, seepage run determinations are needed to quantify the impacts. Seepage run determinations also are needed to quantify streamflow should it return in reaches that are beyond the impact of mining. Proposed paragraph (e) sets forth the baseline information on the biological condition of streams that the application must include. The proposed requirements are substantively identical for both surface and underground mining operations, with the exception that applicants for underground mining operations must submit the required 463 Witherspoon, P.A., J.S.K. Wang, K. Iwai, and J.E. Gale, 1979. Validity of Cubic Law for Fluid Flow in a Deformable Rock Fracture, Water Resources Research, Vol. 16, No. 6, pp. 1016–1024. PO 00000 Frm 00091 Fmt 4701 Sfmt 4702 44525 information for all perennial and intermittent streams within the adjacent area that might possibly be impacted by subsidence resulting from the proposed operation. As discussed in the preamble to our proposed definition of material damage to the hydrologic balance outside the permit area in 30 CFR 701.5, the regulatory authority may not approve any proposed operation that is predicted to cause subsidence that would result in the dewatering of perennial or intermittent streams or that is predicted to result in other adverse impacts that would cause the stream to no longer be capable of supporting existing or reasonably foreseeable uses or that would preclude attainment of designated uses under section 101(a) or 303(c) of the Clean Water Act.464 However, the regulatory authority still would need the information that this paragraph would require for both the area overlying the proposed underground workings and the area within a reasonable angle of draw from the perimeter of those workings to determine whether the operation has created material damage to the hydrologic balance outside the permit area as a result of unanticipated subsidence. This information also would provide a standard for determining when any material damage to the stream has been corrected under 30 CFR 817.121(a). We propose to add paragraph (f)(1)(iv) to the requirements for baseline geologic information for proposed underground mining operations. The new paragraph would require a description of the composition of the base of each perennial and intermittent stream within the proposed permit and adjacent areas, together with a prediction of how that base would be affected by subsidence and how subsidence of the streambed would impact streamflow. This information would be of value in preparation of the PHC determination under proposed 30 CFR 784.20 and the CHIA under proposed 30 CFR 784.21 and in determining whether the proposed operation may result in material damage to the hydrologic balance outside the permit area. Proposed paragraph (h) establishes conditions under which the regulatory authority may grant an exception from the requirement to provide baseline information on the biological condition of streams. It is substantively identical to proposed 30 CFR 780.19(h)(2), except that it includes a provision clarifying that the exception is not available if the proposed operation could cause 464 33 E:\FR\FM\27JYP2.SGM U.S.C. 1251(a) and 1313(c). 27JYP2 44526 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules tkelley on DSK3SPTVN1PROD with PROPOSALS2 subsidence resulting in changes in the base flow of perennial or intermittent streams or in pooling of those streams. Unlike proposed 30 CFR 780.19(h), proposed 30 CFR 784.19(h) does not include an exception for proposed operations for which the area from which coal is to be extracted includes only lands eligible for remining. The purpose of this exception for surface mining operations under proposed 30 CFR 780.19(h)(1) is to provide an incentive to remine previously mined areas by surface mining methods and then reclaim the redisturbed acreage with no expenditure of public funds. However, underground mining operations do not involve surface mining, apart from preparation of the face-up for the underground mine entries. Therefore, underground mining operations are unlikely to result in the remining and reclamation of previously mined areas to any significant extent. Thus, an exception intended to promote the remining and reclamation of previously mined areas would serve little purpose in rules that apply only to underground mining operations. 4. Section 784.20: How must I prepare the determination of the probable hydrologic consequences of my proposed operation (PHC determination)? Proposed section 784.20, which appears at 30 CFR 784.14(e) in the existing rules, is substantively identical to the corresponding proposed rule concerning surface mining at 30 CFR 780.20, with the exception of paragraphs (a)(3), (a)(6), and (a)(7). Proposed paragraph (a)(3), like the existing rule at 30 CFR 784.14(e)(3)(iv), includes provisions consistent with the water replacement requirements of section 720 of SMCRA 465 for underground operations rather than the water replacement requirements of section 717(b) of SMCRA,466 which apply only to surface mines. We propose to add paragraph (a)(6) to require that the PHC determination include a finding on what impact subsidence resulting from the proposed operation may have on perennial and intermittent streams. This finding is critical to a determination of whether the proposed operation would cause material damage to the hydrologic balance outside the permit area, as required by 30 CFR 773.15(e) and section 510(b)(3) of SMCRA.467 In addition, we propose to add paragraph (a)(7), which would require 465 30 U.S.C. 1309a. 466 30 U.S.C. 1307(b). 467 30 U.S.C. 1260(b)(3). VerDate Sep<11>2014 19:15 Jul 24, 2015 that the PHC determination include a finding on whether the proposed underground workings would flood after mine closure and, if so, a statement and explanation of the highest anticipated potentiometric surface of the mine pool after closure; whether, where, and when the mine pool is likely to result in a surface discharge; and the predicted quality of any discharge from the mine pool. The regulatory authority would use this information, in combination with models and calculations of void space and adjacent mine barrier seepage, to predict the probability of a blowout, where and when blowouts might occur, and the likelihood that water discharged as a result of the blowout will require treatment to meet water quality standards or any applicable effluent limitations. The biggest environmental threat from an underground mine is the formation of a post-closure point-source discharge or baseflow discharge that is acidic in character (and thus usually high in metal concentrations) or that contains high total dissolved solids, which result in elevated electrical conductivity in receiving streams. Either characteristic can substantially degrade water quality and the biological condition of streams. Our proposed requirement that the PHC determination include information and a finding on mine pools should enable the applicant to make a business decision as to whether revenue from the proposed operation would be sufficient to justify the cost of preventing future noncompliant discharges of a perpetual nature. It also would enable the regulatory authority to prepare a better CHIA and require the applicant to take discharge prevention measures or change the mining plan to avoid creating a post-closure discharge that would cause material damage to the hydrologic balance outside the permit area in violation of section 510(b)(3) of SMCRA.468 Proposed paragraph (a)(7) also would require that the PHC determination include a statement and explanation of the predicted impact of the mine pool on the hydrologic balance of the proposed permit and adjacent areas after the mine pool reaches equilibrium, the potential for a mine pool blowout or other hydrologic disturbances, the potential for the mine pool to destabilize surface features, and the potential impact of roof collapses on mine pool behavior and equilibrium.

Section 784.21: What requirements apply to preparation and review of the cumulative hydrologic impact assessment (CHIA)? Proposed 30 CFR 784.21 is substantively identical to the CHIA requirements for surface mine permits in proposed 30 CFR 780.21, with one exception: Our proposed CHIA requirements for a permit for an underground mine do not contain a counterpart to the requirement in proposed 30 CFR 780.21(b)(8)(iv) that the regulatory authority find that the proposed operation has been designed to protect the quantity and quality of water in any aquifer that significantly ensures the prevailing hydrologic balance. That provision does not apply to underground mines because section 516(b)(9) of SMCRA,469 which is the underground mining counterpart to section 515(b)(10),470 does not include a counterpart to section 515(b)(10)(D), which requires restoration of the recharge capacity of the mined area to approximate premining conditions. As Congress further recognized in adopting section 720 of SMCRA,471 underground mining operations will necessarily dewater some aquifers. In those situations, section 720 specifies what actions the permittee must take to replace water supplies protected under that section of the law. 6. Section 784.22: What information must I include in the hydrologic reclamation plan and what information must I provide on alternative water resources? Proposed 30 CFR 780.22(a) is substantively identical to the corresponding requirements for surface mine permit applications in proposed 30 CFR 780.22(a), with one exception: Our proposed hydrologic reclamation plan requirements for a permit application for an underground mine do not contain a counterpart to the requirement in proposed 30 CFR 780.22(a)(2)(ix) that the plan demonstrate how the operation will restore the approximate premining recharge capacity. Not including a counterpart to this provision in the underground mining rules is consistent with the difference between sections 515 and 516 of SMCRA,472 as discussed above in the preamble to proposed 30 469 30 U.S.C. 1266(b)(9).

Section 515(b)(10)(D) of SMCRA 473 requires that surface coal mining operations restore the recharge capacity of the mined area to approximate premining conditions. However, this requirement does not appear in the corresponding provision for underground coal mining operations in section 516(b)(9) of SMCRA.474 We also propose to add paragraph (b) to require that an underground mining permit application contain information on alternative water sources. The existing rules concerning underground mining permit applications do not include a similar provision. However, the addition of this requirement would enhance the ability of both the permittee and the regulatory authority to ensure that the water supply replacement requirements of 30 CFR 817.40 and section 720 of SMCRA 475 are properly implemented. Proposed paragraph (b) is substantively identical to the corresponding proposed surface mining requirement at 30 CFR 780.22(b), with the exception that paragraph (b)(1) of section 784.22 reflects the different scope of water supply replacement requirements for underground mining operations, as specified in 30 CFR 817.40 and section 720 of SMCRA.476 7. Section 784.23: What information must I include in my plans for the monitoring of groundwater, surface water, and the biological condition of streams during and after mining? Proposed 30 CFR 784.23 is substantively identical to the corresponding monitoring plan requirements for surface mine permit applications in proposed 30 CFR 780.23, except as discussed below. Proposed 30 CFR 784.23(a)(1)(iii) does not include a requirement that the groundwater monitoring plan provide for monitoring wells to be placed in backfilled portions of the permit area. We did not include this requirement because surface excavations associated with underground mining operations typically are small in size relative to surface mines and do not involve ongoing backfilling and grading activities. Any changes in water quality detected by wells placed in backfilled areas would not be useful in planning changes in future phases of the operation, because there would be no future phases. Instead, we propose to require that the groundwater monitoring plan include at least one monitoring well to be located in the mine pool after 473 30 U.S.C. 1265(b)(10)(D).

This requirement would allow both the permittee and the regulatory authority to monitor changes in mine pool elevation and to evaluate the accuracy of the PHC determination’s prediction of whether the mine pool ultimately will rise to the level that a surface discharge will result. This information is important because water quality in mine pools is often poor,477 which means that any surface discharge would need to be treated, potentially in perpetuity. Proposed paragraphs (a)(1)(iii) and (b)(1)(iv) would require that upgradient and downgradient monitoring points for groundwater and surface water be located at a distance sufficiently close to the underground mine workings to detect changes as the mining operation progresses. The plan must include a schedule and map for moving these sites as the underground workings advance. Without this provision, the upgradient and downgradient monitoring points could be located so far away from the active underground workings that they would provide no meaningful data for purposes of analyzing impacts of current operations on groundwater or surface water. Proposed paragraph (d) establishes conditions under which the regulatory authority may grant an exception from the requirement to monitor the biological condition of streams. It is substantively identical to proposed 30 CFR 780.23(d)(2), except that it includes a provision clarifying that the exception is not available if the proposed operation could cause subsidence resulting in changes in the base flow of a perennial or an intermittent stream or in pooling of a perennial or an intermittent stream. Unlike proposed 30 CFR 780.23(d) for permit applications for surface mines, proposed 30 CFR 784.23(d) does not include an exception for proposed underground mining operations for which the area from which coal is to be extracted includes only lands eligible for remining. The purpose of this exception for surface mining operations under proposed 30 CFR 780.23(d)(1) is to provide an incentive to remine previously mined areas by surface mining methods and then reclaim the redisturbed acreage with no expenditure of public funds. However, underground mining operations do not involve surface mining, apart from preparation 477 Donovan, J. J., B. Leavitt, E. Werner, E. Perry, and K. McCoy, 2000, Long-term Hydrogeological and Geochemical Response to Flooding of an Abandoned Below-drainage Pittsburgh Coal Mine, in the Proceedings of the Twenty-First West Virginia Surface Mine Drainage Task Force Symposium, Morgantown, WV, pp. 139–160.

Therefore, an exception intended to promote the surface mining and reclamation of previously mined areas would serve no purpose in rules that apply only to underground mining operations. 8. Section 784.24: What requirements apply to the postmining land use? Proposed section 784.24 is substantively identical to its proposed surface mining counterpart in 30 CFR 780.24. Both proposed 30 CFR 780.24 and 784.24 would include a modified version of the interpretive rules concerning postmining land use changes for underground mines at 30 CFR 784.200 and 817.200(d)(1), which we propose to remove in concert with this rule change. Please refer to the preamble to proposed 30 CFR 780.24(c) for a discussion of this proposed rule change. 9. Why are we proposing to remove existing 30 CFR 784.26? We propose to remove existing 30 CFR 784.26 because the references to fugitive dust and cross-references to 30 CFR 817.95 in the existing rule refer to provisions that we removed in 1983 in response to a court decision striking down our authority to regulate air pollution under SMCRA, except for air pollution attendant to erosion. The court held that ‘‘the legislative history indicates that Congress only intended to regulate air pollution related to erosion’’ 478 and that ‘‘the Secretary’s authority to regulate [air] pollution is limited to activities related to erosion.’’ 479 The court remanded former 30 CFR 816.95 and 817.95 (1979), which contained performance standards for fugitive dust control, for revision. However, the court did not address the parallel permitting requirements at 30 CFR 780.15 and 784.26. The 1983 rulemaking removed all requirements in 30 CFR 817.95 for fugitive dust control practices, including requirements for monitoring of fugitive dust to determine compliance with federal and state air quality standards. That rulemaking also changed the section heading of 30 CFR 817.95 from ‘‘Air resources protection’’ to ‘‘Stabilization of surface areas’’ and replaced the air quality performance standards formerly located in 30 CFR 817.95 with soil stabilization 478 PSMRL I, Round II, 1980 U.S. Dist.

See 48 FR 1160–1163 (Jan. 10, 1983). However, the 1983 rulemaking did not remove the parallel permitting requirements in 30 CFR 784.26. Instead, we stated in the preamble to that rulemaking that we agreed with a commenter that we also needed to amend the permit application rules at 30 CFR 780.15 and 784.26 for consistency with the revisions to 30 CFR 816.95 and 817.95, and that we would do so in a subsequent independent rulemaking.480 Adoption of this proposed rule would fulfill that long-delayed commitment. With respect to air pollution attendant to erosion, proposed 30 CFR 784.12(f) would add a permitting counterpart to the existing performance standard at 30 CFR 817.95(a), which provides that all exposed surface areas must be protected and stabilized to effectively control erosion and air pollution attendant to erosion. We also propose to add crossreferences to the dust control performance standards for roads in 30 CFR 817.150 and 817.151. We also propose to redesignate existing 30 CFR 784.25, which contains requirements pertaining to the return of coal processing waste to abandoned underground mine workings, as new 30 CFR 784.26. 10. Section 784.26: What information must I provide if I plan to return coal processing waste to abandoned underground workings? We propose to redesignate existing 30 CFR 784.25 as 30 CFR 784.26. We propose to revise redesignated 30 CFR 784.26 by replacing the word ‘‘backfill’’ and its variants with ‘‘backstow’’ or equivalent terminology to avoid any confusion with the process of backfilling open pits or our proposed definition of ‘‘backfill’’ in 30 CFR 701.5. Proposed paragraph (b)(2) would add a requirement for a description of all chemicals used to process the coal, the quantity of those chemicals remaining in the coal processing waste, and the likely impact of those chemicals on groundwater and any persons, aquatic life, or wildlife using or exposed to that groundwater. We propose to revise paragraph (c) to require that the backstowing plan include plans for monitoring the chemicals contained in the coal processing waste and a description of the anticipated effect on biological communities. The regulatory authority needs the information described above to determine whether the proposed backstowing operation 480 48 would cause material damage to the hydrologic balance outside the permit area in violation of section 510(b)(3) of SMCRA.481 We propose to add paragraph (c)(6), which would require that the backstowing plan submitted to the regulatory authority include the measures to be taken to comply with the underground mine discharge requirements of 30 CFR 817.41, when applicable. The inclusion of this provision would serve as a reminder that the permitting requirements of 30 CFR 784.26 are not the only regulations that may apply to review of applications of this nature. We also propose to revise paragraph (d) to clarify that the surface-water and groundwater monitoring plans for the proposed backstowing operation must comply with the requirements of 30 CFR 784.23, which apply to all operations subject to part 784. Finally, we propose to revise paragraph (e) to specify that the regulatory authority may exempt pneumatic backstowing operations from compliance with these requirements if the applicant demonstrates, and the regulatory authority finds in writing, that the proposed pneumatic backstowing operation will not adversely impact surface water, groundwater, or water supplies. The corresponding existing rule at 30 CFR 784.25(e) lacks any requirement for a demonstration by the applicant and it has no criteria for determining when the regulatory authority may grant an exception. Such an open-ended provision is not consistent with the environmental protection purposes and provisions of SMCRA. We invite comment on whether any of the requirements of paragraphs (a) through (d) should apply to all pneumatic backstowing operations, either because the regulatory authority needs that information to decide whether to grant an exemption or because those requirements are needed to ensure that the operation is conducted in an environmentally sound manner. We also invite comment on whether we should adopt similar requirements that would apply to backstowing of coal processing waste in abandoned underground mines when that activity occurs in connection with either a surface coal mine or a coal preparation plant regulated under 30 CFR 785.21.

Section 784.30: When must I prepare a subsidence control plan and what information must that plan include? We propose to redesignate existing 30 CFR 784.20 as 30 CFR 784.30. Proposed 30 CFR 784.30 is substantively identical to existing 30 CFR 784.20. However, existing 30 CFR 784.20(a)(3) contains language that we suspended on December 22, 1999 (64 FR 71652– 71653), in response to a court order vacating those provisions.482 We propose to lift the suspension and then remove the previously suspended language. Specifically, we propose to delete the language in existing 30 CFR 784.20(a)(3) that requires a presubsidence survey of the condition of all noncommercial buildings or occupied residential dwellings and related structures that might be materially damaged by subsidence, or have their reasonably foreseeable value diminished by subsidence, within the area encompassed by the angle of draw. Proposed 30 CFR 784.30(a)(3) would retain the requirement in existing 30 CFR 784.20(a)(3) for a pre-subsidence survey of the condition of the quantity and quality of all drinking, domestic, and residential water supplies within the proposed permit area and the adjacent area. 13. Section 784.35: What information must I provide concerning the minimization and disposal of excess spoil? Proposed 30 CFR 784.35 is substantively identical to its proposed surface mining counterpart at 30 CFR 780.35. Existing 30 CFR 784.19, which is the current underground mining counterpart to 30 CFR 780.35, contains an ambiguous cross-reference to the requirements of 30 CFR 780.35, ‘‘if appropriate.’’ We propose to replace this cross-reference with actual regulatory text and thus eliminate the ambiguity. 482 Nat’l Mining Ass’n v.

Proposed 30 CFR 784.28 is substantively identical to its surface mining counterpart at proposed 30 CFR 780.28, except that proposed 30 CFR 784.28 includes language clarifying that it applies to activities conducted on the land surface. Like existing 30 CFR 784.28, proposed 30 CFR 784.28 would not apply to activities conducted underground or to surface impacts resulting from subsidence caused by underground workings. Sfmt 4702 E:\FR\FM\27JYP2.SGM 27JYP2 tkelley on DSK3SPTVN1PROD with PROPOSALS2 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules Proposed 30 CFR 784.35 also contains revisions to provide consistency with the definition of coal mine waste in 30 CFR 701.5, which we adopted on September 26, 1983 (48 FR 44006). Among other things, that definition reclassified underground development waste as coal mine waste, which means that fills constructed of underground development waste must adhere to the requirements for refuse piles instead of the requirements applicable to excess spoil fills. At the same time that we adopted the definition of coal mine waste in 1983, we revised our performance standards at 30 CFR 817.71 through 817.74 to eliminate the language that combined underground development waste with excess spoil for purposes of performance standards for underground mines. Because the definition of coal mine waste includes underground development waste, the disposal of underground development waste is subject to the performance standards for refuse piles at 30 CFR 817.83 rather than the performance standards for the disposal of excess spoil that applied under the pre-1983 rules. The design requirements for fills in existing 30 CFR 784.19 apply to both underground development waste and excess spoil, which means that those permitting requirements are inconsistent with the 1983 changes to the corresponding performance standards. Proposed 30 CFR 784.35 would apply only to the disposal of excess spoil, consistent with the 1983 changes to our definitions and performance standards regarding coal mine waste. For the same reason, we propose to remove all references to underground development waste in existing 30 CFR 784.19 and to revise the section heading accordingly in concert with our proposed redesignation of existing 30 CFR 784.19 as 30 CFR 784.35. Under proposed 30 CFR 784.35, the permitting requirements for refuse piles in proposed 30 CFR 784.25, not the excess spoil requirements of proposed 30 CFR 784.35, would govern the disposal of underground development waste. Proposed 30 CFR 784.35 parallels proposed 30 CFR 780.35, which contains the permit application requirements for the disposal of excess spoil generated by surface mining activities. As noted above, the existing rule at 30 CFR 784.19 includes those requirements by cross-reference in a somewhat ambiguous fashion. Adding specific language in place of the crossreference to 30 CFR 780.35 in the existing rule would be consistent with the pattern established in most of our VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 other rules for surface and underground mines, in which separately codified provisions for surface and underground mines are nearly identical except for cross-references and the type of operation to which they apply. In addition, adding specific language in place of the cross-reference to 30 CFR 780.35 will allow the inclusion of crossreferences to the appropriate underground mining performance standards in part 817 rather than having to use the cross-references in 30 CFR 780.35 to the surface mining performance standards in part 816. 14. Why are we proposing to remove existing 30 CFR 784.200? Existing 30 CFR 784.200 contains only one interpretive rule, which addresses the use of the permit revision process for postmining land use changes for underground mines. We propose to include this interpretive rule in 30 CFR 784.24 in revised form to the extent that it contains unique provisions not already present in other regulations. Specifically, proposed 30 CFR 784.24(c) would require that any proposed change to a higher or better postmining land use must be processed as a significant permit revision. Please refer to the preamble to proposed 30 CFR 780.24(c) for a discussion of this proposed rule change. We will remove 30 CFR 784.200 if we adopt proposed 30 CFR 784.24(c). J. Part 785: Requirements for Permits for Special Categories of Mining 1. Section 785.14: What special provisions apply to proposed mountaintop removal mining operations? We propose to revise and reorganize 30 CFR 785.14 in accordance with plain language principles. However, we will not discuss those changes here because they are nonsubstantive in nature. With regard to substantive changes, we propose to move existing paragraph (b) to 30 CFR 701.5 as part of our proposed definition of mountaintop removal mining. In proposed paragraph (b)(1), which corresponds to existing paragraph (c)(1), we propose to replace ‘‘land to be affected’’ with ‘‘land to be disturbed’’ to be consistent with the definitions of ‘‘affected area’’ and ‘‘disturbed area’’ in 30 CFR 701.5. This change also would reflect the fact that only lands to be disturbed by the mining operation would have a proposed postmining land use. We propose to remove existing 30 CFR 785.14(c)(3), which provides that the requirements of 30 CFR part 824 must be made a specific condition of the permit. This provision is redundant and PO 00000 Frm 00095 Fmt 4701 Sfmt 4702 44529 unnecessary because the performance standards of 30 CFR part 824 are independently enforceable. Making those performance standards a specific condition of the permit condition adds nothing of value. Furthermore, nothing in SMCRA requires this permit condition. Proposed 30 CFR 785.14(b)(8), like existing 30 CFR 785.14(c)(2), would continue to require that the applicant demonstrate, and the regulatory authority find, that the proposed operation has been designed to comply with the requirements of 30 CFR part 824. Proposed paragraph (b)(9) would replace existing 30 CFR 824.11(a)(9), which prohibits damage to natural watercourses below the lowest coal seam to be mined. We propose to delete the clause limiting the scope of that prohibition to watercourses below the lowest coal seam to be mined because that clause does not appear in the underlying statutory provision. Instead, section 515(c)(4)(D) of SMCRA 483 provides that ‘‘no damage will be done to natural watercourses.’’ However, SMCRA does not define either ‘‘damage’’ or ‘‘natural watercourses.’’ Proposed paragraph (b)(9) would specify that we will consider no damage to have occurred to other natural watercourses if the applicant demonstrates and the regulatory authority finds in writing that all the following conditions exist: • The proposed operation will not increase the amount or concentration of parameters of concern in discharges to groundwater and surface water from the proposed permit area, when compared to the discharges that would occur if the operation were designed to adhere to approximate original contour restoration requirements. • The proposed operation will not result in changes in the size or frequency of peak flows from the proposed permit area that would cause an increase in damage from flooding, when compared to the impacts that would occur if the operation were designed to adhere to approximate original contour restoration requirements. • The total volume of flow from the proposed permit area, during every season of the year, will not vary in a way that would adversely affect any existing or reasonably foreseeable use of surface water or groundwater or any designated use of surface water under section 101(a) or 303(c) of the Clean Water Act.484 483 30 484 33 E:\FR\FM\27JYP2.SGM U.S.C. 1265(c)(4)(D).

We invite comment on whether we can or should instead adopt a rule that would allow the approval of mountaintop removal mining operations that would damage natural watercourses within the permit area if the applicant can demonstrate that the damage will be fully offset by implementation of the fish and wildlife enhancement measures proposed under 30 CFR 780.16. Under proposed paragraph (b)(10), the revegetation plan proposed under 30 CFR 780.12(g) for the operation would have to require that those portions of the proposed permit area that are forested at the time of application or that would revert to forest under conditions of natural succession be revegetated using native tree and understory species to the extent that this requirement is not inconsistent with attainment of the proposed postmining land use. Addition of this requirement would improve implementation of the revegetation requirements of section 515(b)(19) of SMCRA.486 It also would be consistent with section 515(b)(24) of SMCRA,487 which provides that, to the extent possible, surface coal mining and reclamation operations must minimize disturbances to and adverse impacts on fish, wildlife, and related environmental values and enhance those resources where practicable, using the best technology currently available. Proposed paragraph (b)(11) would require that the bond posted for the permit under part 800 of this chapter include an amount equal to the cost of regrading the site to its approximate original contour and revegetating the regraded land in the event that the approved postmining land use is not implemented before expiration of the revegetation responsibility period under § 816.115. As an alternative to requiring posting of this bond amount at the time of permit issuance, we are considering adopting a rule that would prohibit release of any bond amount for the entire permit until the approved postmining land use has been implemented. We invite comment on which alternative would be more effective in preventing abuse of this exception from the AOC restoration requirements of SMCRA. 485 30 U.S.C. 1260(b)(3). 486 30 U.S.C. 1265(b)(19). 487 30 U.S.C. 1265(b)(24). VerDate Sep<11>2014 19:15 Jul 24, 2015 Proposed paragraph (b)(13) would require that the permit clearly identify the acreage and location of mountaintop removal mining areas. Many permits include several types of mining, so the permittee, the regulatory authority, and other interested persons need this information to determine which portions of the permit area are subject to the mountaintop removal mining provisions. Finally, in proposed paragraph (c), we propose to replace the permit review requirements of existing paragraphs (d)(1) and (2) with a cross-reference to the permit review requirements of proposed 30 CFR 774.10(a)(2). Existing paragraph (d)(1) requires a permit review within the sixth month preceding the third year from the date of permit issuance, before each permit renewal, and not later than the middle of each permit term. Proposed 30 CFR 774.10(a)(2) would replace both this provision and a corresponding provision in existing 30 CFR 774.10(a)(3) with language that is consistent with the underlying statutory provision in section 515(c)(6) of SMCRA,488 which requires that permits of this type be reviewed not more than 3 years from the date of permit issuance, unless the permittee affirmatively demonstrates that the proposed development is proceeding in accordance with the terms of the approved schedule and reclamation plan. This review is a one-time requirement, not a recurring event. 2. Section 785.16: What special requirements apply to proposed variances from approximate original contour restoration requirements for steep-slope mining? Proposed Paragraph (a): Application and Approval Requirements We propose to revise 30 CFR 785.16(a) to clarify that a variance approved under this section may apply to only a portion of the permit area rather than to the entire permit area. This change would emphasize that a variance should be limited to the smallest area necessary to accommodate the proposed postmining land use for which the variance is granted. We propose to include the criteria in existing 30 CFR 816.133(d) and 817.133(d) for approval of a variance from approximate original contour requirements in 30 CFR 785.16 because those variances may be granted only for steep-slope mining operations.

Frm 00096 Fmt 4701 Sfmt 4702 make our regulations easier to understand and more user-friendly. Proposed paragraph (a)(8) would allow approval of a variance only if the variance will not result in the construction of a fill in a perennial or an intermittent stream. Sacrificing perennial or intermittent stream segments for the purpose of creating a different postmining land use is neither appropriate nor warranted in view of paragraphs (a) and (d) of section 102 of SMCRA.489 Those paragraphs provide that two of the purposes of SMCRA are to establish a nationwide program to protect society and the environment from the adverse effects of surface coal mining operations and to assure that those operations are conducted in a manner that protects the environment. Proposed paragraph (a)(8) is consistent with section 515(b)(23) of SMCRA,490 which requires that surface coal mining and reclamation operations ‘‘meet such other criteria as are necessary to achieve reclamation in accordance with the purposes of this Act, taking into consideration the physical, climatological, and other characteristics of the site.’’ Addition of this provision also would be consistent with sections 515(b)(24) and 516(b)(11) of SMCRA,491 which require that surface coal mining and reclamation operations be conducted so as to minimize disturbances and adverse impacts on fish, wildlife, and related environmental values to the extent possible, using the best technology currently available. Proposed paragraph (a)(9) would revise the criteria in existing 30 CFR 785.16(a)(3) for determining when the watershed of the proposed permit area and the adjacent area will be deemed improved by the proposed operation. The proposed revisions, which we summarize and discuss below, would promote environmental protection in keeping with the purposes of SMCRA in paragraphs (a), (d), and (f) of section 102 of the Act.492 They also would be consistent with our proposed definition of ‘‘material damage to the hydrologic balance outside the permit area’’ in 30 CFR 701.5. Proposed paragraph (a)(9)(i) would require a demonstration that the proposed operation would reduce the amount or concentration of total suspended solids or other parameters of concern in discharges to groundwater or surface water. The proposed rule corresponds to the first part of existing 489 30 U.S.C. 1202(a) and (d). U.S.C. 1265(b)(23). 491 30 U.S.C. 1265(b)(24) and 1266(b)(11). 492 30 U.S.C. 1202(a), (d), and (f). 490 30 E:\FR\FM\27JYP2.SGM 27JYP2 tkelley on DSK3SPTVN1PROD with PROPOSALS2 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules 30 CFR 785.16(a)(3)(i), which does not mention concentration. We propose to add a reference to concentration because the concentration of parameters of concern in discharges may be more ecologically important than actual amounts under certain conditions. In addition, the existing rule refers to pollutants rather than parameters of concern. We propose to replace ‘‘pollutants’’ with ‘‘parameters of concern’’ because the latter term potentially encompasses a broader range of ecologically important discharge characteristics than would the term ‘‘pollutants.’’ We also propose to delete the somewhat ambiguous language in the existing rule that refers to improvement of public or private uses or the ecology of the water. The language proposed for deletion is not necessary because the critical factor is whether the proposed operation would reduce the amount or concentration of parameters of concern. We propose to revise paragraph (a)(9)(ii), which corresponds to the last part of existing 30 CFR 785.16(a)(3)(i), by adding a reference to the ‘‘size or frequency’’ of peak-flow discharges. Both size and frequency factor into damage from floods, so the applicant and the regulatory authority should consider both factors. Proposed paragraph (a)(9)(iv) would add a requirement for a demonstration that the proposed operation would result in a lesser adverse impact on the aquatic ecology of the cumulative impact area than would occur if the area were to be mined and restored to its approximate original contour. Proposed paragraph (a)(9)(v) would add a requirement for a demonstration that the proposed operation would result in less impact on perennial and intermittent streams than would occur if the land were to be mined and restored to its approximate original contour. The proposed rule would allow the regulatory authority to consider fish and wildlife enhancement measures approved under proposed 30 CFR 780.16 and 784.16 in making this determination. However, fish and wildlife enhancement measures approved under proposed 30 CFR 780.16 and 784.16 may not be used to avoid the prohibition on excess spoil fills in proposed paragraph (a)(8). Proposed paragraphs (a)(10)(i) and (ii) contain the same surface owner consent provisions as existing 30 CFR 785.16(a)(4). We propose to add paragraph (a)(10)(iii), which would specify that the surface owner has not and will not receive any monetary compensation, item of value, or other consideration in exchange for requesting VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 the variance. Proposed paragraph (a)(10)(iii) is consistent with section 102(b) of SMCRA,493 which provides that one of the purposes of the Act is to assure that the rights of surface landowners are fully protected from surface coal mining operations. It also is consistent with section 102(a) of SMCRA,494 which seeks to ‘‘protect society and the environment from the adverse effects of surface mining,’’ by ensuring that variances are requested because they are necessary and appropriate to achieve the approved postmining land use and not due to coercion, deception, or monetary compensation. Proposed paragraph (a)(11) would require a demonstration that the proposed deviations from the premining surface configuration are necessary and appropriate to achieve the approved postmining land use. The intent of this provision is to ensure that variances are granted only for the area necessary to accommodate legitimate postmining land use needs. Proposed paragraph (a)(12) would require the use of native tree and understory species to revegetate all portions of the permit area that are forested at the time of the application or that would revert to forest under conditions of natural succession. This requirement would not apply to permanent impoundments, roads and other impervious surfaces to be retained following the completion of mining and reclamation. It also would not apply to those portions of the permit area covered by the variance if compliance with this requirement would be inconsistent with the attainment of the postmining land use. The intent of this provision is to encourage reforestation of reclaimed lands, where appropriate, and to minimize adverse impacts on fish, wildlife, and related environmental values, as required by sections 515(b)(24) and 516(b)(11) of SMCRA.495 Proposed paragraph (a)(13) would require that the performance bond posted for the permit include an amount equal to the cost of regrading the site to its approximate original contour and revegetating the regraded land in the event that the approved postmining land use is not implemented before expiration of the revegetation responsibility period under 30 CFR 816.115 or 817.115. The intent of this proposed provision is to ensure that variances are granted only for legitimate immediate postmining land use needs. If the postmining land use is not PO 00000 U.S.C. 1202(b).

The bond that this proposed paragraph would require would ensure that the regulatory authority has sufficient funds to complete the reclamation in the event that the permittee fails to do so. As an alternative to requiring posting of this bond amount at the time of permit issuance, we are considering adopting a rule that would prohibit release of any bond amount for the entire permit area until the postmining land use for which the variance was granted has been implemented. We invite comment on which alternative would be more effective in preventing abuse of this exception from the AOC restoration requirements of SMCRA. Proposed Paragraph (b): Regulatory Authority Responsibilities We propose to remove existing paragraph (b)(1), which provides that the requirements of 30 CFR 816.133(d) or 817.133(d) must be included as a specific permit condition. There is no counterpart in SMCRA for this provision. Performance standards are just as enforceable as permit conditions, so there is no reason why these particular performance standards should be made a permit condition. Proposed paragraph (b)(2) would replace the permit review requirements of existing paragraphs (c) and (d) with a cross-reference to the corresponding permit review requirements of 30 CFR 774.10(a), which we propose to revise to be consistent with the underlying statutory provisions in section 515(e)(6) of SMCRA.496 Proposed paragraphs (b)(3) and (4) would include existing paragraphs (e) and (f), respectively, in substantively identical form. Proposed paragraph (b)(5) would require that, before approving a steepslope variance from approximate original contour, the regulatory authority find and document in writing that the surface-owner consent requirements of proposed paragraph (a)(10) have been met. Proposed paragraph (b)(5) is consistent with section 102(b) of SMCRA,497 which provides that one of the purposes of the Act is to assure that the rights of surface landowners are fully protected from 493 30 494 30 Frm 00097 Fmt 4701 Sfmt 4702 44531 496 30 497 30 E:\FR\FM\27JYP2.SGM U.S.C. 1265(e)(6).

Section 785.25: What special provisions apply to proposed operations on lands eligible for remining? We propose to revise 30 CFR 785.25 to improve clarity and to specify that the potential environmental and safety problems that could reasonably be anticipated to occur must be the result of prior mining activities within the proposed permit area. In addition, we propose to specify that the identification of these anticipated problems may be based upon, among other things, a record review of operations near the site and any relevant available information, including data from prior mining activities and remining operations on similar sites. Finally, we propose to delete the term ‘‘mitigative’’ when referring to the measures that will be taken to ensure that reclamation requirements will be met. Mitigation refers to measures to be taken to compensate for the inability to meet reclamation requirements. Hence, the term is not appropriate in the context in which it is used in existing 30 CFR 785.25. tkelley on DSK3SPTVN1PROD with PROPOSALS2 K. Part 800: Bond, Financial Assurance, and Liability Insurance Requirements for Surface Coal Mining and Reclamation Operations. We propose to revise part 800 by adding provisions for the use of financial assurances to guarantee treatment of long-term discharges, modifying the provisions governing alternative bonding systems, and adding more specific criteria and procedures to the provisions governing bond release. In the latter case, we propose to split existing 30 CFR 800.40 into five separate sections (30 CFR 800.40 through 800.44) that address various aspects of the bond release process in greater detail. We also propose to adopt other changes and clarifications, which we discuss below on a section-bysection basis. In addition, for the reasons explained in Part VIII of this preamble, we propose to revise elements of part 800 in accordance with plain language principles. 498 30 U.S.C. 1202(a). VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 1. How do we propose to guarantee treatment of long-term discharges? We propose to add 30 CFR 800.18 and revise other sections of part 800 as appropriate to require that permittees post suitable financial instruments (known as ‘‘financial assurances’’) to guarantee that sufficient funds will be available for the treatment of long-term or perpetual discharges for which a surface or underground coal mine or other facility regulated under SMCRA is responsible. We also propose to add a definition of financial assurance in 30 CFR 800.5 and include necessary and appropriate references to, and provisions for, financial assurances in proposed 30 CFR 800.1, 800.4, 800.13, 800.15, 800.30, and 800.42. Under 30 CFR 773.15(e) and section 510(b)(3) of SMCRA,499 the regulatory authority may not issue a permit unless the application demonstrates, and the regulatory authority finds, that the proposed operation has been designed to prevent material damage to the hydrologic balance outside the permit area. In addition, under 30 CFR 773.15(b) and section 510(b)(2) of SMCRA,500 the regulatory authority may not issue a permit unless the application demonstrates, and the regulatory authority finds, that reclamation as required by the Act and the applicable regulatory program can be accomplished under the reclamation plan approved in the permit. Further, the policy entitled ‘‘Hydrologic Balance Protection: Policy Goals and Objectives on Correcting, Preventing, and Controlling Acid/Toxic Mine Drainage’’ 501 that we issued on March 31, 1997, states, ‘‘[i]n no case should a permit be approved if the determination of probable hydrologic consequences or other reliable hydrologic analysis predicts the formation of a postmining pollutional discharge that would require continuing long-term treatment without a defined endpoint.’’ 502 Improved permitting practices and advances in predictive techniques have almost eliminated acid mine drainage with respect to surface mining permits issued in the last three decades. For example, in Pennsylvania, a state in which acid mine drainage has historically been a widespread and significant problem, a 1999 study 503 U.S.C. 1260(b)(3). U.S.C. 1260(b)(2). 501 See www.osmre.gov/lrg/docs/ amdpolicy033197.pdf (last accessed August 6, 2014). 502 Id., p. 5. 503 Pennsylvania Department of Environmental Protection, ‘‘Evaluation of Mining Permits Resulting in Acid Mine Drainage 1987–1996: A Post Mortem Study’’ (March 1999). PO 00000 499 30 500 30 Frm 00098 Fmt 4701 Sfmt 4702 found that only 17 (one percent) of the 1,699 surface mining permits issued in Pennsylvania between1987 and1996 had long-term postmining discharges that required treatment. In contrast, long-term postmining discharges that required treatment developed on an average of 17 percent of permits issued between1977 and 1983 before the introduction of a science-based permit review program in 1984. However, legacy discharges from older mines remain a concern, as do potential discharges from underground mines after closure. Long-term discharges vary in quality and rate of attenuation. According to one study and literature review, ‘‘surface mines and below-drainage underground mines improve in discharge quality relatively rapidly (20–40 years), [but] abovedrainage underground mines are not as easily predicted.’’ 504 The researchers examined discharges from 44 underground mines in the Pittsburgh and Upper Freeport coal seams in 1968 and again in 1999–2000. During the intervening 30+ years, there were no significant changes in pH, but iron decreased an average of 80 percent, sulfate decreased between 50 percent and 75 percent on average, and total acidity decreased between 56 percent and 79 percent on average.505 While 34 of the 44 mines showed significant improvement in total acidity, 10 showed no change, and 3 became much worse.506 This variability supports our proposal to require that financial assurances for long-term discharges be calculated using a worst-case scenario (treatment in perpetuity) to ensure that sufficient funds will be available for treatment at all times. In addition, there are few studies evaluating the length of time treatment may be needed for other parameters of concern. Section 509(e) of SMCRA 507 requires that the regulatory authority adjust the amount of bond or deposit required and the terms of acceptance of the bond ‘‘where the cost of future reclamation changes.’’ This requirement applies whenever an unanticipated discharge requiring long-term treatment develops. However, conventional bond instruments (surety bonds, collateral bonds, and self-bonds) are not optimal for this purpose because, under conditions of forfeiture, they provide a one-time lump sum payout rather than the income stream needed to fund 504 Demchak, J.; J. Skousen; and L. M. McDonald. Longevity of Acid Discharges from Underground Mines Located above the Regional Water Table, J. Environ.

Surety bonds and self-bonds are especially ill-suited for this purpose because (1) the need for discharge treatment may outlast the surety or the permittee and (2) neither a surety bond nor a self-bond requires that funds or other assets be physically placed with the regulatory authority or in an account dedicated solely to the regulatory authority, which means that funds would not necessarily be available to continue treatment if the surety and the permittee go out of business before the need for treatment ends. Furthermore, surety companies normally do not underwrite a bond when there is no expectation of release of liability, as would be the case with almost all longterm discharges because there is no reliable prospect of fully abating the source of the discharge. Section 509(c) of SMCRA 508 provides that ‘‘the Secretary may approve as part of a State or Federal program an alternative system that will achieve the objectives and purposes of the bonding program pursuant to this section.’’ This provision affords statutory authority for our proposal in 30 CFR 800.18 to allow the use of financial assurances in place of conventional bonds when a continuing income stream is needed to meet ongoing treatment requirements for long-term discharges. Existing 30 CFR 800.11(e), which we propose to redesignate as 30 CFR 800.9, provides that, to meet the objectives and purposes of the bonding program, the alternative system (1) ‘‘must assure that the regulatory authority will have available sufficient money to complete the reclamation plan for any areas which may be in default at any time;’’ and (2) ‘‘must provide a substantial economic incentive for the permittee to comply with all reclamation provisions.’’ Establishment of a financial assurance in the form of a trust fund or annuity would satisfy the first criterion, while the permittee’s provision of the moneys needed to establish the trust fund or annuity and the express terms of the trust would satisfy the second criterion. We relied upon this statutory authority to adopt similar financial assurance provisions at 30 CFR 942.800 as part of the Tennessee federal regulatory program.509 As we did in the Tennessee rulemaking, we propose to elaborate upon and incorporate into regulation pertinent elements of the policy entitled ‘‘Hydrologic Balance Protection: Policy Goals and Objectives on Correcting, Preventing, and 508 30 509 72 U.S.C. 1259(c). FR 9616 (Mar. 2, 2007). VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 Controlling Acid/Toxic Mine Drainage’’ 510 that we adopted on March 31, 1997. Specifically, Objective 2 under the ‘‘Environmental Protection’’ policy goal includes the following strategies: Strategy 2.2—If, subsequent to permit issuance, monitoring identifies acid- or toxicforming conditions which were not anticipated in the mining and operation plan, the regulatory authority should require the operator to adjust the financial assurance. Strategy 2.3—Where inspections conducted in response to bond release requests identify surface or subsurface water pollution, bond in an amount adequate to abate the pollution should be held as long as water treatment is required, unless a financial guarantee or some other enforceable contract or mechanism to ensure continued treatment exists.511 The policy acknowledges that ‘‘the required financial assurance may take a form other than those associated with a traditional performance bond.’’ 512 In 2002, we published an advance notice of proposed rulemaking entitled ‘‘Bonding and Other Financial Assurance Mechanisms for Treatment of Long-Term Pollutional Discharges and Acid/Toxic Mine Drainage (AMD) Related Issues.’’ See 67 FR 35070 (May 17, 2002). In that notice, we sought comments on, among other things, the form and amount of financial assurance that should be required to guarantee treatment of postmining discharges. Commenters disagreed as to whether financial assurance should be required, but they largely agreed that, if it was, surety bonds are not the best means— or even an appropriate means—of accomplishing that purpose because a surety bond is not designed to provide the income stream needed to fund ongoing treatment. We provided the following explanation of the statutory basis for the requirement that permittees post financial guarantees for treatment of long-term discharges. Section 509(a) of the Act requires that each permittee post a performance bond conditioned upon faithful performance of all the requirements of the Act and the permit. Paragraph (b) of this Section of the Act specifies that ‘‘[t]he amount of the bond shall be sufficient to assure the completion of the reclamation plan if the work had to be performed by the regulatory authority in the event of forfeiture.’’ The hydrologic reclamation plan is part of the reclamation plan to which this section refers. Section 519(c) of SMCRA authorizes release of this bond only when the regulatory authority is satisfied that the reclamation required by the 510 See www.osmre.gov/lrg/docs/ amdpolicy033197.pdf (last accessed August 6, 2014). 511 Id., p. 6. 512 Id., p. 15 (response to comment 16). PO 00000 Frm 00099 Fmt 4701 Sfmt 4702 bond has been accomplished, and paragraph (c)(3) specifies that ‘‘no bond shall be fully released until all reclamation requirements of this Act are fully met.’’ Furthermore, section 519(b) of the Act provides that whenever a bond release is requested, the regulatory authority must conduct an inspection to evaluate the reclamation work performed, including ‘‘whether pollution of surface or subsurface water is occurring, the probability of continuance of future occurrence of such pollution, and the estimated cost of abating such pollution.’’ Therefore, there is no doubt that, under SMCRA, the permittee must provide a financial guarantee to cover treatment of postmining discharges when such discharges develop and require treatment.513 The financial assurance elements of this proposed rule rely upon the same rationale. In addition, our financial assurance requirements in proposed 30 CFR 800.18 derive support from the following discussion in a Federal district court decision affirming our disapproval of a West Virginia regulatory program amendment that would have authorized final bond release upon installation of a passive treatment system for long-term discharges: SMCRA and its accompanying regulations comprise an intricate and complicated scheme, which contains a wealth of Congressional policies and purposes. See, e.g., 30 U.S.C. 1201, 1202. Further, the overriding policies of SMCRA, minimization of environmental damage and maximization of coal production, necessarily are in tension with each other. It is within this delicate framework that OSM regulates. * * * * * The balance in the Director’s approach, consistent with congressional direction, is readily ascertainable. The Director begins with the proposition that complete prevention of AMD [acid mine drainage] during mining and reclamation may not be possible and the associated environmental burden, with treatment, is judged tolerable resulting in a permit being issued. At this interim juncture, then, environmental considerations give way to the goal of maximizing coal production for the nation’s energy requirements. Once an operator decides to close up shop and leave, however, it then would be inconsistent to allow the treatment guarantee to lapse, potentially saddling the taxpayers and adjoining landowners with a perpetual financial and environmental problem that should have been internalized by the operator. At this final stage, environmental considerations and cost internalization assume ultimate priority over the goal of maximization of production to require the total abatement of AMD. The Director has thus struck a reasonable balance in the face of Congressional ambiguity and difficult, conflicting policy considerations. Given satisfaction of the 513 Id., E:\FR\FM\27JYP2.SGM pp. 14–15 (response to comment 16). 27JYP2 44534 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules Chevron inquiry, the Court is bound to defer to that interpretation.514 The court noted that ‘‘a bedrock principle of SMCRA is the obligation of the mine operator to bear the costs associated with surface mining, from the permitting of a mining operation through to the conclusion of the reclamation process.’’ 515 In a footnote, the court observed that— Even were treatment acceptable for bond release, the lingering difficulty with the proposed amendment is its hands-off approach to passive treatment. An operator conceivably could erect a passive treatment system, gain release and the system could later fail, leaving the taxpayers and adjoining landowners with a burden contrary to the policy of cost internalization. Such a burden could not have been intended by Congress.516 tkelley on DSK3SPTVN1PROD with PROPOSALS2 Proposed 30 CFR 800.18 seeks to avoid precisely this burden and result. Finally, finding 1.b.(2) in the preamble to the document announcing our decision on another West Virginia program amendment provision contains the following rationale for requiring that permittees post performance bonds adequate to guarantee ongoing treatment of discharges: For conventional bonds, 30 CFR 800.14(b) provides that ‘‘the amount of the bond shall be sufficient to assure the completion of the reclamation plan if the work had to be performed by the regulatory authority in the event of forfeiture.’’ Under 30 CFR 780.18(b)(9), 780.21(h), 784.13(b)(9), and 784.14(g), the reclamation plan must include the steps to be taken to comply with all applicable effluent limitations and State and Federal water quality laws and regulations. These steps include treatment. Therefore, when the mining and reclamation plan indicates that treatment will be needed on a temporary basis during mining and the early stages of reclamation, the bond must be calculated to include an amount adequate to provide for continued temporary treatment in the event forfeiture occurs within the timeframe during which treatment is needed. Also, under 30 CFR 800.15(a), the regulatory authority is required to adjust the amount and terms of a conventional bond whenever the cost of future reclamation changes. Therefore, if an unanticipated treatment need arises, the regulatory authority has an obligation to order an increase in the minimum bond required for the site. This amount must be adequate to cover all foreseeable treatment costs. This interpretation is consistent with the preamble to 30 CFR 800.17, which under the heading ‘‘Section 800.17(c)’’ states that: ‘‘Performance bonding continues to be required at § 800.17(a) for surface disturbances incident to underground mining 514 West Virginia Mining and Reclamation Ass’n et al. v.

Completion of the reclamation plan as it relates to mine drainage and protection of the hydrologic balance would continue to be covered by the bond with respect to requirements included in § 784.14. 48 FR 32948, July 19, 1983.’’ Sections 780.21(h) and 784.14(g) require a hydrologic reclamation plan showing how surface and underground mining operations will comply with applicable State and Federal water quality laws and regulations. Furthermore, section 519(b) of SMCRA requires the regulatory authority, when evaluating bond release requests, to consider whether pollution of surface and ground water is occurring, the probability of any continuing pollution, and the estimated cost of abating such pollution. Section 519(c)(3) of SMCRA and the implementing regulations at 30 CFR 800.40(c)(3) provide that no bond shall be fully released until all the reclamation requirements of the Act, the regulatory program, and the permit have been met. These requirements include abatement of surface and ground water pollution resulting from the operation.517 While proposed 30 CFR 800.18 focuses on financial assurance instruments (trust funds and annuities) to provide the necessary income stream, it also recognizes that collateral bonds can, under certain circumstances, be a satisfactory means of guaranteeing treatment of long-term discharges because collateral bonds require the posting of cash, securities, or other collateral. Specifically, proposed 30 CFR 800.18(b)(2) would allow the use of collateral bonds provided that the amount of the collateral bond posted includes the cost of treating the discharge during the time required to collect and liquidate the bond and convert the proceeds to a financial instrument that will generate interest in an amount sufficient to cover future treatment costs and associated administrative expenses. 2. How do we propose to revise the definitions in 30 CFR 800.5? We propose to revise existing 30 CFR 800.5(b)(6), which is part of the definition of ‘‘collateral bond,’’ to delete the reference to ‘‘investment-grade rated securities having a rating of AAA, AA, or A or an equivalent rating issued by a nationally recognized securities rating service.’’ According to the Department of the Treasury regulations at 12 CFR 16.2, a security is considered investment grade if it is rated in one of the top four rating categories by each nationally recognized statistical rating organization that has rated the security. Our rules include only those securities with ratings in the top three categories. In addition, unlike the Treasury PO 00000 517 60 FR 51902 (Oct. 4, 1995). Frm 00100 Fmt 4701 Sfmt 4702 regulations, we do not require that the security receive these ratings from all organizations that have rated the security. Therefore, we propose to revise 30 CFR 800.5(b)(6) to eliminate the reference to ‘‘investment-grade’’ securities and to instead use language consistent with a similar provision in 30 CFR 800.23(b)(3)(i). We also propose to replace the term ‘‘nationally recognized securities ratings service’’ with the term found in the Credit Rating Agency Reform Act of 2006 (Pub. L. 109–291) and used by the Securities and Exchange Commission: ‘‘Nationally recognized statistical rating organization.’’ As revised, our proposed rule would include securities with a rating of ‘‘A’’ or higher from either Moody’s Investors Service or Standard and Poor’s or an equivalent rating issued by any other nationally recognized statistical rating organization registered with the Securities and Exchange Commission. In existing paragraph (d), we propose to define ‘‘financial assurance’’ as ‘‘a trust fund, an annuity, or a combination thereof.’’ We invite comment on whether there are other investment vehicles that could provide the income stream needed to guarantee treatment of long-term discharges and therefore should be included in this definition. 3. Section 800.9: What requirements apply to alternative bonding systems? We propose to redesignate the provisions for alternative bonding systems in existing 30 CFR 800.11(e) as new 30 CFR 800.9(a). Proposed 30 CFR 800.9(b) would clarify that the alternative bonding system will apply in lieu of the performance bond requirements of part 800 to the extent specified in the regulatory program and the document in which we approve the alternative bonding system as part of a state or federal program. Proposed paragraph (b) also would specify that all alternative bonding systems must include provisions analogous to the bond release provisions of proposed 30 CFR 800.40 through 800.44 and the bond forfeiture provisions of 30 CFR 800.50. This provision is necessary to ensure that the regulatory program, including the alternative bonding system, remains consistent with section 519 of SMCRA,518 which governs bond release, which in turn determines when the regulatory authority may terminate jurisdiction over the operation in accordance with 30 CFR 700.11(d). Proposed 30 CFR 800.9(c) would clarify that an alternative bonding system may be structured to include only certain 518 30 E:\FR\FM\27JYP2.SGM U.S.C. 1269. 27JYP2 tkelley on DSK3SPTVN1PROD with PROPOSALS2 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules phases of reclamation under proposed 30 CFR 800.42, provided that the other phases are covered by one of the forms of bond listed in 30 CFR 800.12. This provision would ensure that the entire operation has bond coverage, as required by section 509 of SMCRA.519 Proposed 30 CFR 800.9(d)(1) would prohibit an alternative bonding system from covering restoration of the ecological function of a stream under 30 CFR 780.28, 784.28, 816.57, and 817.57. Alternative bonding systems are not appropriate or reliable mechanisms to guarantee restoration of the ecological function of a stream, given the length of time that we anticipate will be required to restore that function. Furthermore, restoration should be the responsibility of the individual, company, or other mining entity that makes the decision to mine through a stream. Existing alternative bonding systems were not established with the expectation that they might have to cover the costs of restoring the ecological function of a stream. Exposing those systems to these unanticipated costs could compromise their fiscal integrity. Proposed 30 CFR 800.9(d)(2)(i) would prohibit an alternative bonding system from covering treatment of long-term discharges that come into existence after the effective date of paragraph (d), unless, upon discovery of the discharge, the permittee contributes an amount sufficient to cover all costs that the alternative bonding system will incur to treat the discharge in perpetuity and the alternative bonding system sets that money aside in a separate account dedicated solely to treatment of that discharge. Otherwise, consistent with proposed 30 CFR 800.18, the permittee would be required to post a financial assurance, a collateral bond, or a combination thereof to cover this obligation. Financial assurances are preferred because they produce an income stream, but the permittee has the option of posting a sufficiently large collateral bond to cover all foreseeable treatment and reclamation costs. Self-bonds are neither appropriate nor reliable for this purpose because they do not require the deposit of any funds with the regulatory authority or under the control of the regulatory authority. Therefore, the regulatory authority may not be able to recover the necessary funds if the permittee goes out of business. In that case, there would be no dedicated funding set aside to ensure continued treatment of the discharge, which means either that treatment would cease, resulting in environmental damage, or that a governmental entity would assume treatment, meaning that the public would bear the cost of avoiding environmental damage. Under proposed 30 CFR 800.9(d)(2)(ii), long-term discharges that came into existence before the effective date of paragraph (d) would continue to be covered by any applicable state alternative bonding system unless the regulatory authority amends its program to specifically establish an earlier effective date. The proposed rule would require that the permittee of a site with a discharge subject to paragraph (d)(2)(ii) contribute to the alternative bonding system an amount sufficient to cover all costs that the regulatory authority estimates that the alternative bonding system will incur to treat the discharge for as long as the discharge requires active or passive treatment to meet Clean Water Act standards or pertinent SMCRA-related requirements. The proposed rule would require that the alternative bonding system place that amount in a separate account available only for treatment of the discharge for which the contribution is made. The proposed rule further provides that a permittee unable to make this contribution must post a financial assurance, a collateral bond, or a combination thereof to cover this obligation. 4. Section 800.11: When and how must I file a bond? We propose to redesignate existing 30 CFR 800.11(e) as 30 CFR 800.9. We propose to streamline the remaining provisions of existing 30 CFR 800.11 and improve the wording and structure to clarify their meaning. We also propose to add a requirement that the bond be filed in the amount that the regulatory authority determines necessary under 30 CFR 800.14. In addition, we propose to delete a mostly obsolete provision in existing 30 CFR 800.11(c) specifying that an operator ‘‘may not extend any underground shafts, tunnels or operations’’ before the regulatory authority accepts the performance bond required for that area. This provision is inconsistent with section 509(a) of SMCRA,520 which requires a performance bond only for that area of land within the permit area upon which the operator will conduct surface coal mining and reclamation operations. Paragraphs (27) and (28) of section 701 of SMCRA 521 define surface coal mining and reclamation operations, in relevant part, as ‘‘activities conducted on the surface of lands’’ and ‘‘the areas 520 30 519 30 U.S.C. 1259.

Frm 00101 Fmt 4701 Sfmt 4702 44535 upon which such activities occur or where such activities disturb the natural land surface.’’ Therefore, SMCRA does not require posting of performance bond for underground workings. Proposed paragraph (d) would replace the mostly obsolete provision in existing paragraph (c) with a prohibition on disturbing any surface area (by any type of surface coal mining operation) or extending any vertical underground mine shaft or other vertical underground mine opening for which a performance bond is required before the regulatory authority accepts the performance bond required for that area or extension. A performance bond is required for extension of vertical underground mine shafts and other vertical underground mine openings because those openings must be filled upon the completion of mining and the depth of the opening will affect the cost of reclamation. 5. Section 800.12: What form of bond is acceptable? The first sentence of existing 30 CFR 800.12 provides that the regulatory authority must prescribe the form of the bond. We propose to redesignate this sentence as paragraph (a). The remainder of existing 30 CFR 800.12 provides that the regulatory authority may allow the permittee to post a surety bond, a collateral bond, a self-bond, or a combination of these forms of bond. We propose to redesignate this provision as paragraph (b) and add paragraphs (c) through (e) to identify exceptions and special requirements. Proposed paragraph (c) would clarify that an alternative bonding system approved under proposed 30 CFR 800.9 is not subject to 30 CFR 800.12. Proposed paragraph (d) reflects the fact that proposed 30 CFR 800.18 would require that a permittee post either a financial assurance or a collateral bond to guarantee treatment of a long-term discharge. Consistent with proposed 30 CFR 780.28(c), 784.28(c), 816.57(b), and 817.57(b), proposed paragraph (e) would require that the permittee post a surety bond, a collateral bond, or a combination thereof to guarantee restoration of the ecological function of a stream segment. A self-bond is not an appropriate mechanism to guarantee restoration of a stream’s ecological function because of the risk that the company may cease to exist during the time required to accomplish that restoration. In addition, a self-bond does not require that the permittee file financial instruments or collateral with the regulatory authority, nor is there any third party obligated to complete the E:\FR\FM\27JYP2.SGM 27JYP2 44536 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules reclamation or pay the amount of the bond if the permittee defaults on reclamation obligations. tkelley on DSK3SPTVN1PROD with PROPOSALS2 6. Section 800.13: What is the liability period for a bond? Existing 30 CFR 800.13(b) allows separate bonding of isolated and clearly defined portions of the permit area that require extended liability. We propose to revise this paragraph to allow those provisions to apply to the bond posted to guarantee restoration of a stream’s ecological function under proposed 30 CFR 780.28, 784.28, 816.57, and 817.57. The proposed addition would recognize that restoring the premining ecological function of a stream segment is a lengthy process. We also propose to revise paragraph (b) to require that access routes to any separately bonded areas be included within those areas. Under the existing rule, bonding of these routes is discretionary on the part of the regulatory authority. However, we see no basis under section 509 of SMCRA to exclude any disturbed areas from bonding requirements unless those areas are fully reclaimed and are no longer used for any activity related to mining and reclamation. Existing paragraph (d) provides that the permittee is responsible under the bond for restoring the disturbed area to a condition capable of supporting the approved postmining land use. It further provides that the permittee’s responsibility does not extend to actual implementation of the approved use. We propose to revise this paragraph to reflect the proposed revisions to 30 CFR 785.16(a)(13), which would impose alternative reclamation requirements on the permittee if the postmining land use forming the basis for a variance from the approximate original contour restoration requirements is not implemented by the end of the revegetation responsibility period. We also propose to add a provision clarifying that proposed 30 CFR 800.18 would govern the liability period for long-term treatment of discharges. 7. Section 800.14: How will the regulatory authority determine the amount of bond required? We propose to revise existing 30 CFR 800.14(a) by adding the biological condition of perennial and intermittent streams within the permit area to the list of factors that the regulatory authority must consider in establishing bond amounts. This revision is consistent with our proposal to require restoration of the ecological function of perennial and intermittent streams under 30 CFR 780.28, 784.28, 816.57, and 817.57. Streams with a more pristine biological VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 condition may be more difficult to restore and thus may require a higher bond amount. We propose to revise existing 30 CFR 800.14(b) by adding paragraph (b)(2) to require that the calculations used to determine the bond amount specifically identify the amount of bond needed to restore stream function. Under proposed paragraph (b)(2), the permittee then would have the option of either posting a separate bond for that amount or incorporating it into the bond posted for the entire permit or increment. We propose to redesignate existing 30 CFR 800.14(c) as paragraph (f) and add a new paragraph (c) to reflect the proposed revisions to 30 CFR 785.16(a)(13), which would impose alternative reclamation requirements on the permittee if the postmining land use forming the basis for a variance from approximate original contour restoration requirements is not implemented by the end of the revegetation responsibility period. Specifically, we propose to require that the amount of the bond be sufficient to restore the variance area to its approximate original contour if the approved postmining land use is not implemented by the end of the applicable revegetation responsibility period. This proposed requirement is intended to minimize any potential abuse of the steep-slope variance provision. Proposed 30 CFR 800.14(d) would clarify that proposed 30 CFR 800.18 would govern the amount of the financial assurance required to guarantee long-term treatment of discharges. Proposed 30 CFR 800.14(e) is substantively identical to the provision in existing paragraph (b) establishing that the total bond posted for the entire area under one permit may not be less than $10,000, as required by the last clause of section 509(a) of SMCRA.522 8. Section 800.15: When must the regulatory authority adjust the bond amount and when may I request adjustment of the bond amount? We propose to revise existing 30 CFR 800.15(a) to more clearly distinguish between bond adjustments under section 509(e) of SMCRA 523 and bond releases under section 519 of SMCRA.524 Specifically, as discussed below, we propose to incorporate into regulation our interpretation of section 509(e) of SMCRA,525 which we explain in the preamble to the existing rules and PO 00000 526 https://www.osmre.gov/LRG/docs/ directive882.pdf (last accessed October 28, 2014). 527 48 FR 32944 (Jul. 19, 1983). 528 Id. at 32945. 529 30 U.S.C. 1259(e). 522 30 U.S.C. 1259(a). 523 30 U.S.C. 1259(e). 524 30 U.S.C. 1269. 525 30 U.S.C. 1259(e). Frm 00102 Fmt 4701 in Directive TSR–1, ‘‘Handbook for Calculation of Reclamation Bond Amounts.’’ 526 Section 509(e) of SMCRA provides that ‘‘[t]he amount of the bond or deposit required and the terms of each acceptance of the applicant’s bond shall be adjusted by the regulatory authority from time to time as affected land acreages are increased or decreased or where the cost of future reclamation changes.’’ The preamble to existing 30 CFR 800.15(c) states that ‘‘reduction of bond is considered a bond adjustment if the reduction is based on a change in method of operation or other circumstances which reduces the estimated cost for the regulatory authority to reclaim.’’ 527 It further states that ‘‘any reduction in bond amount for reclamation work performed on disturbed areas’’ does not qualify as a bond adjustment because ‘‘bond for disturbed areas can only be released or reduced through formal release procedures of § 800.40.’’ 528 Proposed 30 CFR 800.15(a) would clarify that, consistent with existing policy, the changes in the cost of reclamation to which section 509(e) of SMCRA 529 refers are limited to decreases in the cost of future reclamation as a result of (1) the approval of revisions to the operation and reclamation plan in the permit or (2) changes in the unit costs of future reclamation; e.g., the cost of moving a cubic yard of spoil x number of feet, the cost of planting x number of trees, or the hourly cost to operate a specified piece of equipment. Situations that qualify for bond reduction through the bond adjustment process on this basis would include technological advances that would reduce the unit costs of reclamation, approved revisions to the operation plan (such as a decision not to remove the lowest coal seam) that would result in an operation of more limited extent than originally approved and bonded, and approved revisions to the reclamation plan (such as an alteration in the postmining land use) that would reduce reclamation costs. A bond reduction under 30 CFR 800.15 on the basis of a change in the cost of reclamation must be justified solely upon a demonstration that the reclamation cost estimates that form the basis for the existing bond amount are no longer valid for reasons other than completion of elements of the reclamation process. We propose to add language specifying that the bond Sfmt 4702 E:\FR\FM\27JYP2.SGM 27JYP2 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules adjustment provisions may not be used to reduce the amount of the performance bond to reflect decreases in the cost of future reclamation as a result of completion of activities required under the reclamation plan approved in the permit. Bond reduction for completed reclamation activities such as backfilling or topsoil replacement may be accomplished only in accordance with the bond release requirements and procedures of proposed 30 CFR 800.40 through 800.44. Any bond reduction requested as a result of reclamation work performed must be submitted and processed as an application for bond release under proposed 30 CFR 800.40 through 800.44. Under proposed 30 CFR 800.15(e), the regulatory authority would have to require that appropriate bond or financial assurance be posted in accordance with proposed 30 CFR 800.18 whenever a discharge that will require long-term treatment is identified. Proposed 30 CFR 800.15(f) would prohibit reduction of the bond amount to reflect the failure of the permittee to restore the approximate original contour or when the reclamation plan was improperly modified to reflect the level of reclamation completed rather than the level of reclamation required under the regulatory program. tkelley on DSK3SPTVN1PROD with PROPOSALS2 9. Section 800.16: What are the general terms and conditions of the bond? Existing 30 CFR 800.16(e) states that the bond must provide a mechanism for banks and sureties to give prompt notice to the regulatory authority and the permittee of any action filed alleging the insolvency or bankruptcy of the permittee, bank, or surety or alleging any violations that would result in suspension or revocation of the bank’s or surety’s license or charter to do business. We propose to revise this paragraph so that it would apply not just to banks and sureties, but also to any other responsible financial entity that issues bonds. We see no logical or legal reason to limit the scope of this requirement to banks and sureties. We also propose to move existing 30 CFR 800.16(e)(2), which sets forth the actions that the permittee and regulatory authority must take in the event of incapacity of a bank or surety, to 30 CFR 800.30(b). This provision is not a term or condition of the bond. Therefore, it is more appropriately located in 30 CFR 800.30, which is the section that contains requirements for replacement of bonds. VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 10. Why are we proposing to remove existing 30 CFR 800.17? Existing 30 CFR 800.17 contains bond requirements for underground coal mines and long-term coal-related surface facilities and structures. We propose to remove this section because it largely duplicates provisions of other sections of part 800. The only unique provision authorizes the posting of bond instruments with defined expiration dates, provided the bond is conditioned upon extension, replacement, or payment in full 30 days before the expiration date. The rule also requires that the regulatory authority initiate bond forfeiture proceedings if the permittee has not filed a term extension or a replacement bond 30 days before the expiration date. This provision was originally adopted under the authority of section 516(d) of SMCRA,530 which requires consideration of ‘‘the distinct difference between surface and underground coal mining’’ in developing regulations applying the bond requirements of section 509 of SMCRA 531 to underground mines. Specifically, section 800.17 provides a limited exception to the following provision in section 509(b) of SMCRA: ‘‘Liability under the bond shall be for the duration of the surface coal mining and reclamation operation and for a period coincident with [the] operator’s responsibility for revegetation requirements in section 515.’’ This exception is no longer necessary because underground mines can obtain letters of credit and other bonds just as other surface coal mining operations do. 11. Section 800.18: What special provisions apply to financial guarantees for treatment of long-term discharges? Proposed 30 CFR 800.18 would establish performance bond and financial assurance requirements that would apply whenever any discharge from a surface or underground coal mine or other facility regulated under SMCRA requires treatment and continues or may reasonably be expected to continue after the completion of mining, backfilling, grading, and the establishment of revegetation. Part IX.K.1. of this preamble explains the rationale for requiring a bond or financial assurance to guarantee treatment of long-term discharges and for the use of financial assurances in place of conventional bond instruments. We also propose to apply these requirements to situations in which the PO 00000 530 30 531 30 U.S.C. 1266(d). U.S.C. 1259. Frm 00103 Fmt 4701 Sfmt 4702 44537 regulatory authority finds that a discharge requiring long-term treatment will develop in the future, provided that the quantity and quality of the future discharge can be determined with reasonable probability. In these situations, it would be prudent to require that the permittee establish a trust fund or annuity during the mining phase when revenues are available. If the regulatory authority does not require establishment of a trust fund or annuity until the discharge actually develops, the permittee may no longer be in business or may lack the resources to establish a trust fund or annuity. One example of an operation that would meet these criteria is an underground mine that creates a mine pool that will reach surface elevations and begin to discharge at some point after mine closure. Proposed paragraph (b) would specify that only financial assurances and collateral bonds are acceptable forms of bond to guarantee treatment of longterm discharges. As discussed in Part IX.K.1. of this preamble, surety bonds and self-bonds are not appropriate instruments because neither would produce the income stream needed to cover treatment expenses and because there is a distinct possibility that the discharge would outlast both the permittee and the surety. If the permittee elects to post a collateral bond rather than a financial assurance, the rule would require that the amount of the collateral bond include the cost of treating the discharge during the time needed to collect and liquidate the bond and convert the proceeds to a financial instrument that will generate interest in an amount sufficient to cover future treatment costs and associated administrative expenses. To minimize threats to the solvency of alternative bonding systems, we propose to prohibit those systems from covering treatment of long-term discharges unless the permittee posts an amount equal to the cost of treating the discharge in perpetuity and the alternative bonding system places that money in a separate account dedicated solely to treatment of that discharge. However, the proposed rule would grandfather in operations with discharges covered by an alternative bonding system on the effective date of this new provision. Proposed paragraph (c) would specify that the amount of financial assurance or collateral bond required must include the cost of treating the discharge to meet all applicable numerical standards or limits that are in effect at the time that the regulatory authority issues an order requiring posting of a financial assurance or bond. The numerical E:\FR\FM\27JYP2.SGM 27JYP2 tkelley on DSK3SPTVN1PROD with PROPOSALS2 44538 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules standards or limits may be established in a SMCRA permit (the criteria for material damage to the hydrologic balance outside the permit area), in a permit or authorization issued under the Clean Water Act (an NPDES permit, a section 404 dredge or fill permit or authorization, or a section 401 water quality certification), or in regulations implementing the Clean Water Act. Proposed paragraph (d) would establish requirements for the financial assurance instrument itself. We based these provisions on the experience of the Pennsylvania and Tennessee regulatory authorities in establishing and managing trust funds and annuities to guarantee long-term treatment of discharges. Proposed paragraph (d) would require that the trust fund or annuity be in a form approved by the regulatory authority and contain all terms and conditions required by the regulatory authority. The trust fund or annuity would have to be established in a manner that guarantees that sufficient moneys will be available when needed to pay for treatment costs in perpetuity (unless the permittee demonstrates, and the regulatory authority finds, based on scientifically proven facts, that treatment will be needed for a lesser time, either because the discharge will attenuate or because its quality will improve); periodic maintenance, renovation, and replacement of treatment and support facilities; final reclamation of the sites upon which treatment facilities are located and areas used in support of those facilities; and administrative costs incurred by the regulatory authority or trustee. Calculations of the amount required for the trust fund or annuity would have to be based on a conservative anticipated rate of return on the proposed investments that is consistent with longterm historical rates of return for similar investments. The regulatory authority would be required to specify the investment objectives of the trust fund or annuity to ensure that those objectives are consistent with production of an income stream adequate to meet ongoing treatment needs. The trust fund or annuity must irrevocably establish the regulatory authority as the beneficiary of the trust fund or of the proceeds from the annuity for the purpose of treating mine drainage or other mining-related discharges to protect the environment and users of surface water. Proposed paragraph (d)(1)(i) would allow permittees a reasonable time to fully fund trust funds and annuities rather than requiring a lump-sum deposit as would be required for collateral bonds. Under the proposed VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 rule, the regulatory authority could accept an arrangement by which the permittee builds the amount of the trust fund or annuity over time, provided that the permittee continues to treat the discharge during that time; and the regulatory authority retains all performance bonds posted for the permit until the trust fund or annuity reaches a self-sustaining level as determined by the regulatory authority. This provision is needed because some permittees may require additional time to obtain the financing needed to establish a trust fund or annuity for treatment of unanticipated discharges. Insisting on immediate funding of the full cost of a trust fund or annuity could force the permittee into a default on reclamation or other obligations, which could be counterproductive if it results in the permittee ceasing treatment or if it disrupts or precludes the allocation of funds for treatment or other reclamation activities. Proposed paragraph (d)(6) would require that the trust fund or annuity provide that disbursement of money from the trust fund or annuity may be made only upon written authorization of the regulatory authority or according to a schedule established in the agreement accompanying the trust fund or annuity. We anticipate that a fully funded trust or annuity may include provisions for disbursements to the permittee as a mechanism to cover the cost of water treatment, especially for those permittees no longer generating income from the mining of coal. Disbursements from the income stream of a fully funded trust fund or annuity would not be considered a bond release or a bond forfeiture because we propose to adopt these financial assurance provisions as an alternative bonding system for the specific purpose of producing the income stream needed to pay for treatment and related costs. Proposed paragraph (d)(7) would provide that the financial institution or company serving as a trustee or issuing an annuity must be one of the following: • A national bank chartered by the Office of the Comptroller of the Currency. • An operating subsidiary of a national bank chartered by the Office of the Comptroller of the Currency. • A bank or trust company chartered by the state in which the operation is located. • An insurance company licensed or authorized to do business in the state in which the operation is located or designated by the pertinent regulatory body of that state as an eligible surplus lines insurer. PO 00000 Frm 00104 Fmt 4701 Sfmt 4702 • Any other financial institution or company with trust powers and with offices located in the state in which the operation is located, provided that the institution’s or company’s activities are examined or regulated by a state or federal agency. This proposed restriction is intended to ensure that only competent, reliable, and properly capitalized and insured companies are eligible for selection as trustees. We invite comment on whether the proposed list is too inclusive or exclusive. Proposed paragraph (e) would allow termination of a trust fund or annuity only upon the demise of the trustee or the company issuing the annuity or as specified by the regulatory authority upon a determination that one of the following situations exists: • No further treatment or other reclamation measures are necessary. • A satisfactory replacement bond or financial assurance has been posted. • The terms of the trust fund or annuity establish conditions for termination and those conditions have been met. • The trustee’s administration of the trust fund or annuity is unsatisfactory to the regulatory authority, in which case the permittee or the regulatory authority must procure a new trustee. We invite comment on whether there are any other situations in which termination should be allowed or required. Proposed paragraph (f) would require that the regulatory authority establish a schedule for reviewing the performance of the trustee, the adequacy of the trust fund or annuity, and the accuracy of the assumptions upon which the trust fund or annuity is based. We propose to require that these reviews occur on at least an annual basis, but we invite comment on whether a different review frequency would be more appropriate and why. The rule would require that the regulatory authority order the permittee to provide additional resources to the trust fund or annuity whenever the review or any other information available to the regulatory authority at any time demonstrates that the financial assurance is no longer adequate to meet the purpose for which it was established. Proposed paragraph (g) provides that the bond replacement provisions of 30 CFR 800.30(a) would govern the replacement of any financial assurance. Proposed paragraph (h) specifies that release of reclamation liabilities and obligations under financial assurances would be subject to the applicable bond release provisions of proposed 30 CFR 800.40 through 800.44. E:\FR\FM\27JYP2.SGM 27JYP2 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules Proposed paragraph (i) provides that the permittee may apply for, and the regulatory authority may approve, release of any bonds posted for the permit or permit increment for which the regulatory authority has approved a financial assurance, provided that the permittee and the regulatory authority comply with the bond release requirements and procedures in proposed §§ 800.40 through 800.44. This provision would apply only if the financial assurance is in place and fully funded, the permit or permit increment fully meets all applicable reclamation requirements (with the exception of the discharge and the presence of associated treatment and support facilities), and the financial assurance will serve as the bond for reclamation of the portion of the permit area required for postmining water treatment facilities and access to those facilities. Release of all other bonds for the site would be appropriate under these conditions because the fully funded trust fund or annuity would be available to fund treatment and reclamation activities in the event of a permittee’s bankruptcy or dissolution. tkelley on DSK3SPTVN1PROD with PROPOSALS2 12. Section 800.21: What additional requirements apply to collateral bonds? We propose to revise existing 30 CFR 800.21(a)(3) to allow the acceptance of certificates of deposit issued by financial institutions other than banks. We also propose to revise existing 30 CFR 800.21(a)(4) and (d)(4) to eliminate references to the now-defunct Federal Savings and Loan Insurance Corporation and references to the obsolete $100,000 maximum on the amount insured by the Federal Deposit Insurance Corporation. The proposed revisions would make this section consistent with the current structure and nomenclature of the financial industry and its regulators. 13. Section 800.23: What additional requirements apply to self-bonds? We propose to revise existing 30 CFR 800.23(b)(3)(i) to allow the use of any nationally recognized statistical rating organization (NRSRO) registered with the Securities and Exchange Commission in determining whether a corporation is eligible to self-bond. The existing rule allows use of only Moody’s Investors Service and Standard and Poor’s. The proposed revision is consistent with the Credit Rating Agency Reform Act of 2006 (Pub. L. 109–291), which facilitated the entry of new credit rating organizations into the market by abolishing the authority of the Securities and Exchange Commission (SEC) to designate NRSROs by no-action letters and replacing that process with a provision that, to be VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 recognized as an NRSRO, a rating agency must register with the SEC. As stated in section 2(5) of the Credit Rating Agency Reform Act of 2006, ‘‘the 2 largest credit rating agencies serve the vast majority of the market, and additional competition is in the public interest.’’ Therefore, our existing rule requiring use of either Moody’s or Standard and Poor’s in determining selfbonding eligibility is no longer appropriate. 14. Section 800.30: When may I replace a bond or financial assurance instrument and when must I do so? We propose to revise this section by combining existing 30 CFR 800.30(a) and (b) into paragraph (a) and by deleting an unnecessary sentence in existing 30 CFR 800.30(b) stating that replacement of a performance bond does not constitute bond release. We also propose to extend the applicability of this section to financial assurances under proposed 30 CFR 800.18, and to redesignate the mandatory bond replacement provisions of existing 30 CFR 800.16(e)(2) as 30 CFR 800.30(b). Proposed paragraph (a) would allow the regulatory authority to decline to accept a proffered replacement surety bond if, in the judgment of the regulatory authority, the new surety does not have adequate reinsurance or other resources sufficient to cover the default of one or more mining companies for which the surety has provided bond coverage. This proposed provision is intended to avoid a repeat of the situation involving Frontier Insurance Company in the 1980s in which the surety could not meet its obligations. Proposed paragraph (b) would extend the applicability of existing 30 CFR 800.16(e)(2) to include other responsible financial entities issuing bonds. The existing language in 30 CFR 800.16(e)(2) applies only to banks and sureties, but we see no logical reason to exclude other bond-issuing entities from the scope of this paragraph. We also propose to revise this paragraph to clarify that failure to replace a bond within the specified time is a violation for which the regulatory authority must issue a notice of violation. Operating without bond coverage would be a violation of the permit condition required under 30 CFR 773.17(a). 15. Section 800.40: How do I apply for release of all or part of a bond? We propose to redesignate existing 30 CFR 800.40(a) as new section 800.40, with two substantive revisions. First, we propose to require that the applicant submit a certified copy of the required PO 00000 Frm 00105 Fmt 4701 Sfmt 4702 44539 newspaper advertisement. Addition of the certification requirement would provide independent documentation that the newspaper advertisement has indeed been published for the required 4 weeks. Second, we propose to require that the description of the results achieved under the approved reclamation plan include an analysis of the results of the monitoring of groundwater, surface water, and the biological condition of perennial and intermittent streams under 30 CFR 816.35 through 816.37 or 817.35 through 817.37. This analysis is critical to a determination of whether reclamation requirements relating to protection of the hydrologic balance have been met. 16. Section 800.41: How will the regulatory authority process my application for bond release? We propose to redesignate existing 30 CFR 800.40(b)(1) as section 800.41 and restructure the existing rule as paragraphs (a) and (b) of section 800.41. We also propose two substantive revisions. First, proposed paragraph (a)(1) would specify that the regulatory authority’s clock for processing the application begins only upon submittal of a complete application rather than upon receipt of any application. Second, proposed paragraph (a)(2) would clarify that a complete application for bond release is one that includes all items required under 30 CFR 800.40. The proposed additions would benefit both the applicant and the regulatory authority by ensuring that an application is complete before the review process begins, which would have the additional benefit of promoting the efficient use of resources. 17. Section 800.42: What are the criteria for bond release? We propose to redesignate existing 30 CFR 800.40(c) as 30 CFR 800.42, with a number of substantive revisions. Proposed paragraph (a) sets forth the general requirements that would have to be met before the regulatory authority may approve an application for bond release and release all or part of the bond in accordance with the other paragraphs of 30 CFR 800.42. Proposed paragraph (a) would apply to all types of bond release applications (Phase I through Phase III). In general, sections 509(a) and 519(b) of SMCRA 532 provide authority for the proposed revisions. Section 509(a) 533 provides, in relevant part, that the amount of bond in place for a surface coal mining and 532 30 533 30 E:\FR\FM\27JYP2.SGM U.S.C. 1259(a) and 1269(b).

Section 519(b) of SMCRA 534 provides that the regulatory authority’s evaluation of a bond release application must ‘‘consider, among other things, the degree of difficulty to complete any remaining reclamation, whether pollution of surface and subsurface water is occurring, the probability of continuance of future occurrence of such pollution, and the estimated cost of abating such pollution.’’ Proposed paragraphs (a)(2) through (a)(6) are intended to ensure that the regulatory authority takes these factors into consideration. Proposed paragraph (a)(2) would not allow the regulatory authority to release any bond if, after an evaluation of the monitoring data for groundwater, surface water, and the biological condition of perennial and intermittent streams submitted under proposed 30 CFR 816.35 through 816.37 or 817.35 through 817.37, it determines that adverse trends exist that may result in material damage to the hydrologic balance outside the permit area. This provision is intended to prevent premature release of bond that may be needed to correct potentially expensive damage to the hydrologic balance. This proposed requirement is consistent with section 515(b)(23) of SMCRA,535 which requires that surface coal mining and reclamation operations ‘‘meet such other criteria as are necessary to achieve reclamation in accordance with the purposes of this Act, taking into consideration the physical, climatological, and other characteristics of the site.’’ Proposed paragraph (a)(3) would prohibit the release of any portion of the bond unless and until the permittee posts a financial assurance or collateral bond under proposed 30 CFR 800.18 if a discharge requiring long-term treatment exists either on the permit area or at a point that is hydrologically connected to the permit area. Adoption of this proposed paragraph would incorporate into regulation one of the strategies in the policy entitled ‘‘Hydrologic Balance Protection: Policy Goals and Objectives on Correcting, 534 30 535 30 U.S.C. 1269(b). U.S.C. 1265(b)(23). VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 Preventing, and Controlling Acid/Toxic Mine Drainage’’ that we issued on March 31, 1997. Specifically, Strategy 2.3 of Objective 2 under the ‘‘Environmental Protection’’ goal provides that— Strategy 2.3—Where inspections conducted in response to bond release requests identify surface or subsurface water pollution, bond in an amount adequate to abate the pollution should be held as long as water treatment is required, unless a financial guarantee or some other enforceable contract or mechanism to ensure continued treatment exists.536 Proposed paragraph (a)(4) would apply whenever the permit area or increment includes a variance under 30 CFR 785.16 from restoration of the approximate original contour. In that case, the proposed rule would prohibit release of the portion of the bond described in proposed 30 CFR 785.16(a)(13), in whole or in part, until the approved postmining land use is implemented or until the site is restored to the approximate original contour and revegetated in accordance with 30 CFR 816.111 and 816.116 or 817.111 and 817.116. This provision is intended to prevent abuse of the steep-slope variance provision and to ensure that variances are requested and granted only when there is a reasonable likelihood of achieving the alternative postmining land use, as provided in the requirements for approval of higher or better land uses under section 515(b)(2) of SMCRA.537 Authority for this provision derives in part from section 515(e)(5) of SMCRA,538 which provides that the regulatory authority ‘‘shall promulgate specific regulations to govern the granting of variances in accord with the provision of this subsection, and may impose such additional requirements as he deems to be necessary.’’ Proposed paragraph (a)(5) pertains to buildings and structures to be retained as part of the approved postmining land use. It would prohibit release of the bond amount described in proposed 30 CFR 780.24(d)(2) or 784.24(d)(2) either until the structure is in use as part of the postmining land use or until the structure is removed and the site upon which it was located is reclaimed in accordance with part 816 or part 817. This provision is intended to ensure that only structures with actual utility for the postmining land use are retained. 536 ‘‘Policy Goals and Objectives on Correcting, Preventing and Controlling Acid/Toxic Mine Drainage,’’ OSMRE, March 31, 1997.

There would be no funds available to remove structures retained as part of the postmining land use at the time of bond release if they subsequently deteriorate. Proposed 30 CFR 800.42(a)(6) would require that the regulatory authority consider the results of the evaluation required under proposed 30 CFR 816.41(a)(3) when determining the amount of bond to release. Proposed 30 CFR 816.41(a)(3) requires that the evaluation consider, among other factors, the degree of difficulty to complete any remaining reclamation, whether pollution of surface and subsurface water is occurring, the probability of future occurrence of such pollution, and the estimated cost of abating such pollution. The factors listed in the proposed rule are identical to the factors listed in section 519(b) of SMCRA.539 Proposed paragraph (b) would include the criteria for Phase I bond release in existing 30 CFR 800.40(c)(1). We propose to revise the existing criteria by adding a provision clarifying that restoration of the form of perennial and intermittent stream segments mined through under 30 CFR 816.57 or 817.57 is part of the backfilling and grading process and therefore must be accomplished before the area is eligible for Phase I bond release. We also propose to add a provision stating that the amount of bond that the regulatory authority retains after Phase I release must be adequate to ensure that the regulatory authority will have sufficient funds for a third party to complete the remaining portion of the reclamation plan, including restoration of the ecological function of perennial and intermittent streams under 30 CFR 816.57 or 817.57 and completion of any fish and wildlife enhancement measures required in the permit in accordance with 30 CFR 780.16 or 784.16, in the event of forfeiture. The proposed additional requirements are necessary and appropriate to ensure compliance with section 509(a) of SMCRA,540 which provides, in relevant part, that the amount of bond in place for a surface coal mining and reclamation operation ‘‘shall be sufficient to assure the completion of the reclamation plan if the work had to be performed by the regulatory authority in the event of forfeiture.’’ 539 30 540 30 E:\FR\FM\27JYP2.SGM U.S.C. 1269(b).

Proposed paragraph (b) would clarify that section 519(c)(1) of SMCRA 542 does not stand alone; i.e., that release of the entire 60 percent is neither required nor allowed if releasing that amount of money would result in retention of insufficient bond to cover remaining reclamation costs, as required by section 509(a) of SMCRA.543 Proposed paragraph (c) would include the criteria for Phase II bond release in existing 30 CFR 800.40(c)(2). Proposed paragraph (c)(1) would revise the existing criteria by adding a requirement that the regulatory authority establish standards for determining when revegetation has been successfully established for purposes of this paragraph. Establishment connotes an element of permanence. However, except for prime farmland, revegetation need not meet the entire suite of revegetation success standards under 30 CFR 816.116 or 817.116 to qualify for Phase II bond release. Otherwise, there would be little practical difference between the criteria for Phase II and Phase III bond release if the revegetation responsibility period must expire before a site is eligible for Phase II bond release. We invite comment on whether we should provide national standards for establishment of revegetation for purposes of Phase II bond release or whether this decision is best left to the judgment of the regulatory authority, based on local conditions. We also propose to add a provision in proposed paragraph (c)(2) stating that the amount of bond that the regulatory authority retains after Phase II release must be adequate to ensure that the regulatory authority will have sufficient funds for a third party to complete the remaining portion of the reclamation plan, including restoration of the ecological function of perennial and intermittent streams under 30 CFR 816.57 or 817.57 and completion of any fish and wildlife enhancement measures required in the permit in accordance with 30 CFR 780.16 or 784.16, in the event of forfeiture.

We invite comment on the meaning of ‘‘silt dam’’ as used in proposed paragraph (c)(5) and in section 519(c)(2) of SMCRA.545 Proposed paragraph (d) would include the criteria for Phase III (final) bond release in existing 30 CFR 800.40(c)(3).

Section 800.43: When and how must the regulatory authority provide notification of its decision on a bond release application? Proposed 30 CFR 800.43(a) is substantively identical to existing 30 CFR 800.40(b)(2). Proposed 30 CFR 800.43(b) and (c) are substantively identical to existing 30 CFR 800.40(d) and (e), respectively. 19.

Part 816: Permanent Program Performance Standards—Surface Mining Activities In this preamble, we typically discuss only those sections and paragraphs for which we propose substantive revisions. For the reasons explained in Part VIII of this preamble, we propose to revise other sections and paragraphs within this part in accordance with plain language principles, to update crossreferences, and to improve consistency. In general, we do not discuss those proposed changes because no substantive change in meaning is intended. 545 30 Jkt 235001 PO 00000 U.S.C. 1269(c)(2). Frm 00107 Fmt 4701 1. Section 816.1: What does this part do? Existing 30 CFR 816.1 provides that part 816 sets forth the minimum environmental protection performance standards to be adopted and implemented under regulatory programs for surface mining activities. However, the content requirements and approval criteria for state regulatory programs are located at 30 CFR parts 730 through 732. Therefore, we propose to revise this section to simply state that it sets forth the environmental protection performance standards for surface mining activities under the Act. 2. Section 816.2: What is the objective of this part? Existing 30 CFR 816.2 provides that the objective of part 816 is to ensure that all surface mining activities are conducted in a manner that preserves and enhances environmental and other values in accordance with the Act. However, SMCRA does not require preservation and enhancement of all values in all cases. Instead, as stated in section 102(f) of the Act,546 one of the purposes of the Act is to ‘‘strike a balance between protection of the environment and agricultural productivity and the Nation’s need for coal as an essential source of energy.’’ Therefore, we propose to revise 30 CFR 816.2 to state that the objective of part 816 is to ensure that surface mining activities are conducted in an environmentally sound manner in accordance with the Act. 3. Section 816.11: What signs and markers must I post? The existing rules contain four requirements to mark buffer zones for perennial and intermittent streams—one in the stream buffer zone rule for surface mining operations at 30 CFR 816.57(b), one in the stream buffer zone rule for underground mining operations at 30 CFR 817.57(b), one in the requirements for signs and markers for surface mining operations at 30 CFR 816.11(e), and one in the requirements for signs and markers for underground mining operations at 30 CFR 817.11(e). We propose to consolidate those requirements into 30 CFR 816.11(e) and 817.11(e). Proposed 30 CFR 816.11(e) would provide that the boundaries of any buffer to be maintained between surface mining activities and perennial or intermittent streams in accordance with proposed 30 CFR 780.28 and 816.57 must be clearly marked to avoid disturbance by surface mining activities. 546 30 Sfmt 4702 44541 E:\FR\FM\27JYP2.SGM U.S.C. 1202(f). 27JYP2 44542 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules 4. Section 816.22: How must I handle topsoil, subsoil, and other plant growth media? General Discussion of Basis for Proposed Revisions In general, our proposed revisions to this section would improve implementation of section 515(b)(6) of SMCRA,547 which requires that surface coal mining operations ‘‘restore the topsoil or the best available subsoil which is best able to support vegetation,’’ and section 515(b)(5) of SMCRA,548 which states that surface coal mining operations must— tkelley on DSK3SPTVN1PROD with PROPOSALS2 remove the topsoil from the land in a separate layer, replace it on the backfill area, or if not utilized immediately, segregate it in a separate pile from other spoil and when the topsoil is not replaced on a backfill area within a time short enough to avoid deterioration of the topsoil, maintain a successful cover by quick growing plant or other means thereafter so that the topsoil is preserved from wind and water erosion, remains free of any contamination by other acid or toxic material, and is in a usable condition for sustaining vegetation when restored during reclamation, except if topsoil is of insufficient quantity or of poor quality for sustaining vegetation, or if other strata can be shown to be more suitable for vegetation requirements, then the operator shall remove, segregate, and preserve in a like manner such other strata which is best able to support vegetation. Existing 30 CFR 816.22 focuses primarily on topsoil handling. We propose to revise this section and its permitting counterpart at 30 CFR 780.12(e) to require salvage, protection, and redistribution of soil materials in addition to the topsoil to ensure that the reconstructed soil on the reclaimed minesite provides a root zone of sufficient depth and comprised of appropriate soil and overburden materials that will create a plant growth medium suitable for the vegetation to be planted. The existing regulations are either unclear on this point (see existing paragraphs (a)(1)(ii) and (2), which sometimes have been interpreted as meaning that soil materials other than topsoil need be salvaged, stored, and redistributed only if the topsoil is less than 6 inches thick or is of poor quality) or, in the case of existing paragraph (e), make salvage of soil materials other than topsoil discretionary on the part of the regulatory authority. The revised performance standards in proposed paragraphs (a), (b), and (e) of 30 CFR 816.22 and the soil-handling plan required by proposed 30 CFR 780.12(e) would require salvage, protection, storage, and redistribution of 547 30 548 30 U.S.C. 1265(b)(6).

In addition, Forest Reclamation Advisory No. 8 (one of the publications implementing and supporting the Forestry Reclamation Approach) states that deep soil is required for productive tree growth and that ‘‘[s]alvaging and re-spreading only the upper few inches or horizons of soil is unlikely to restore premining capability unless additional materials suitable for reforestation are added.’’ 551 Furthermore, the following excerpt from a U.S. District Court for the District of Columbia decision in PSMRL I, Round I concerning the 1979 version of our regulations at 30 CFR 816.22(d), which required segregation of the B horizon and portions of the C horizon if the regulatory authority determined that those materials were necessary or desirable to ensure soil productivity, provides support for our proposed revisions: Section 515(b)(5) [of SMCRA] authorizes segregation [of materials other than topsoil] if the topsoil cannot sustain vegetation or if other strata enhance post-mining vegetation. This is essentially what the regulations command. They focus on ‘‘soil productivity,’’ and grant the regulatory authority power to require segregation if necessary to improve such productivity.552 Proposed Paragraph (a): Removal and Salvage Proposed paragraph (a) would require that the permittee separately remove and salvage all topsoil and other soil materials identified for salvage and use as postmining plant growth media in the soil-handling plan approved in the permit under § 780.12(e).

Like the existing rule, it provides an exemption for minor disturbances. The proposed rule differs from the existing rule primarily in that it requires removal and salvage of all topsoil and other soil and overburden materials needed to reconstruct a suitable postmining plant growth medium throughout the root zone required to support the vegetation to be planted after the completion of mining. The existing rule requires removal and salvage of only topsoil, topsoil substitutes, or the top 6 inches of material when the topsoil is less than 6 inches in depth. As discussed above, in most cases, that material would result in a postmining plant growth medium of insufficient depth to support all land uses that the land was capable of supporting before any mining, which would be inconsistent with section 515(b)(2) of SMCRA.553 Proposed Paragraph (b): Storage The stockpiling requirements and temporary distribution provisions of proposed paragraph (b) are substantively identical to those of existing paragraph (c), with the exception that we propose to add a requirement that any species used to establish a vegetative cover on stockpiles be non-invasive to avoid endangering the success of efforts to revegetate the site with plants native to the area. Proposed Paragraph (c): Soil Substitutes and Supplements Proposed paragraph (c) provides that when the soil handling plan approved in the permit in accordance with § 780.12(e) provides for the use of substitutes for or supplements to the existing topsoil or subsoil, the permittee must salvage, store, and redistribute the overburden materials selected and approved for that purpose in a manner consistent with paragraphs (a), (b), and (e) of section 816.22. It is the counterpart to existing paragraph (a)(1)(ii), but differs in that it applies to all soil substitutes and supplements, not just to topsoil substitutes and supplements. We propose to move the approval standards for soil substitutes and supplements from existing paragraph (b) to 30 CFR 780.12(e) as part of our effort to consolidate permitting requirements in subchapter G rather than having them split between 553 30 E:\FR\FM\27JYP2.SGM U.S.C. 1265(b)(2). 27JYP2 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules the permitting requirements of subchapter G and the performance standards of subchapter K. Proposed Paragraph (d): Site Preparation Proposed paragraph (d)(1) would require that the permittee minimize grading of backfilled areas to avoid compaction of the reconstructed root zone, as specified in the soil-handling plan approved in the permit in accordance with § 780.12(e). The rule would allow compaction only to the extent necessary to ensure stability and to comply with water-quality standards. Loosely graded soil materials have less compaction, greater water infiltration, and less erosion than more intensely graded soil materials.554 Greater infiltration generally makes more water available for plant growth and less erosion may result in a reduced frequency for cleanouts of sedimentation ponds.555 As stated in one research report: Third-year results show that intensive grading did not result in better ground cover establishment or erosion control. In fact, erosion was highest on the intensively graded plots.556 tkelley on DSK3SPTVN1PROD with PROPOSALS2 Limited compaction is also more favorable to tree root growth, which will increase survival and growth rates and promote the establishment of productive forest land on reclaimed minesites.557 Proposed paragraph (d)(2) would require that, if necessary, the permittee rip, chisel-plow, or otherwise mechanically treat backfilled and graded areas before topsoil redistribution to reduce potential slippage of redistributed material placed on slopes and to promote root penetration. This provision is substantively identical to existing paragraph (d)(2) except that we propose to specify that the treatment must be mechanical in nature (ripping and chisel-plowing are the two most common methods) because we are not aware of any other effective type of treatment. 554 Sweigard, R., J.

VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 Proposed Paragraph (e): Redistribution Proposed paragraph (e) includes soil redistribution requirements analogous to those of existing paragraph (d)(1). The proposed rule differs from the redistribution requirements in the existing rule primarily in that the proposed rule would apply to all salvaged soil and soil substitute materials, not just to topsoil and topsoil substitutes and supplements, as in the existing rule. In addition, the proposed rule not only would require minimization of compaction to the extent possible (a requirement that is similar to the existing rule’s ban on excess compaction); it would require that the permittee take measures to alleviate any excess compaction that does occur, which would minimize adverse impacts on site productivity and plant growth. We propose to remove existing paragraph (d)(4), which requires application of nutrients and soil amendments to initially-redistributed soil material when necessary to reestablish vegetative cover. The revegetation component of the reclamation plan required under proposed 30 CFR 780.12 governs the use of nutrients and soil amendments. Finally, proposed paragraph (e) would require use of a statistically-valid sampling technique to document that soil materials have been redistributed in the locations and to the depths required by the soil-handling plan approved in the permit in accordance with § 780.12(e). We encourage use of EPA’s Data Quality Objectives model,558 which is a seven-step method to assist in assuring that the appropriate type, quantity, and quality of data are collected for decision-making purposes. Site-specific variability should be taken into account when designing a sampling program and caution is recommended in the selection of composite versus discrete sampling methods for certain soil constituents. We invite comment on whether use of the EPA Data Quality Objectives model or its equivalent should be mandatory. Proposed Paragraph (f): Organic Matter Proposed paragraph (f) would require the salvage of organic matter found on the site, including duff, other organic litter, and vegetative materials such as tree tops, small logs, and root balls. We propose to prohibit the burning or burying of these materials. Instead, for 558 ‘‘Guidance on Systematic Planning Using the Data Quality Objectives Process,’’ (EPA QA/G–4), EPA/240/B–06/001, February 2006; available at https://www.epa.gov/quality/qa_docs.html (last accessed August 7, 2014). PO 00000 Frm 00109 Fmt 4701 Sfmt 4702 44543 the reasons discussed at slightly greater length in the preamble to proposed 30 CFR 780.12(e), proposed paragraph (f) would require that the permittee redistribute the salvaged materials across the regraded surface or incorporate them into the soil to control erosion, promote growth of vegetation, serve as a source of native plant seeds and inoculants such as mycorrhizae, speed restoration of the soil’s ecological community and ecosystem processes, and increase the moisture retention capability of the soil. Proposed paragraph (f) is consistent with Forest Reclamation Advisory No. 8, which states that ‘‘[w]hen soil is obtained from forested areas prior to mining, the salvage operation should take stumps, roots, and woody debris left on the site, transport them to the reclaimed area, and re-spread them with the soil.’’ 559 The rule also would allow the use of woody debris for stream restoration purposes and to construct fish and wildlife habitat enhancement features. Proposed paragraph (f) would enhance implementation of section 515(b)(19) of SMCRA,560 which requires that surface coal mining and reclamation operations establish ‘‘a diverse, effective, and permanent vegetative cover of the same seasonal variety native to the area of land to be affected and capable of self-regeneration and plant succession.’’ It also would improve implementation of section 515(b)(24) of SMCRA,561 which requires that surface coal mining and reclamation operations, ‘‘to the extent possible using the best technology currently available, minimize disturbances and adverse impacts of the operation on fish, wildlife, and related environmental values, and achieve enhancement of such resources where practicable.’’ 5. Section 816.34: How must I protect the hydrologic balance? This new section would incorporate, reorganize, and consolidate paragraphs (a), (b), and (d) of existing 30 CFR 816.41. Those paragraphs contain general requirements for protection of the hydrologic balance as well as provisions specific to protection of groundwater and surface water. Proposed Paragraph (a) Proposed paragraph (a) is primarily comprised of existing 30 CFR 816.41(a). However, proposed paragraph (a)(3) would add a requirement to protect streams within the permit area, unless 559 Skousen, et al. (2011), op. cit. at 3.

This provision would enhance implementation of section 515(b)(24) of SMCRA,562 which requires that surface coal mining and reclamation operations be conducted to minimize adverse impacts on fish, wildlife, and related environmental values to the extent possible using the best technology currently available. In addition, proposed paragraphs (a)(4) and (5) would clarify and refine the scope of existing 30 CFR 816.41(a), which requires the ‘‘protection or replacement of water rights.’’ Proposed paragraph (a)(4) would require that the permittee assure the protection or replacement of water supplies to the extent required by 30 CFR 816.40. Proposed paragraph (a)(5) would require that the permittee protect existing water rights under state law. (Water rights are determined by state law.) Proposed paragraphs (a)(4) and (5) better reflect the provisions of section 717 of SMCRA,563 which contains the water rights and water supply replacement requirements applicable to surface mines. With respect to water rights, section 717(a) 564 provides that nothing in SMCRA ‘‘shall be construed as affecting in any way the right of any person to enforce or protect, under applicable law, his interest in water resources affected by a surface coal mining operation.’’ With respect to water supply replacement, section 717(b) 565 provides that— tkelley on DSK3SPTVN1PROD with PROPOSALS2 The operator of a surface coal mine shall replace the water supply of an owner of interest in real property who obtains all or part of his supply of water for domestic, agricultural, industrial, or other legitimate use from an underground or surface source where such supply has been affected by contamination, diminution, or interruption proximately resulting from such surface coal mine operation. Proposed paragraph (a)(4) relates to section 717(b) of SMCRA,566 while proposed paragraph (a)(5) relates to section 717(a) of SMCRA.567 Proposed paragraphs (a)(8) and (10) correspond to existing 30 CFR 816.41(b)(1) and (d)(1), respectively. We propose to revise the existing rules by adopting language that more closely follows the language of section 515(b)(10)(A) of SMCRA.568 Specifically, we propose to replace requirements in the existing rules to 562 30 U.S.C. 1265(b)(24). U.S.C. 1307. 564 30 U.S.C. 1307(a). 565 30 U.S.C. 1307(b). 566 30 U.S.C. 1307(b). 567 30 U.S.C. 1307(a). 568 30 U.S.C. 1265(b)(10)(A). 563 30 VerDate Sep<11>2014 19:15 Jul 24, 2015 minimize acidic or toxic drainage with requirements to avoid acid or toxic mine drainage. In addition, we propose to add a requirement for use of the best technology currently available. Section 515(b)(10) of SMCRA 569 uses this phrase only in paragraph (B)(i), which pertains to suspended solids. However, proposed paragraphs (a)(8) and (10) of this rule would require use of the best technology currently available to meet the requirements of section 515(b)(10)(A) 570 as well. Application of this standard to all surface-water and groundwater protection activities is appropriate because section 515(b)(24) of SMCRA 571 requires use of the best technology currently available to minimize adverse impacts on fish, wildlife, and related environmental values. Surface water and groundwater quality are related environmental values in this context. In proposed paragraph (a)(11), which is the counterpart to existing 30 CFR 816.41(d)(2), we propose to add a crossreference to the surface-water runoff control plan that would be required by proposed 30 CFR 780.29. Proposed Paragraph (b) Proposed paragraph (b)(1) is substantively identical to the last sentence in existing 30 CFR 816.41(a) except that we propose to expand its scope to include a requirement that the permittee use mining and reclamation practices that minimize adverse impacts on stream biota rather than relying upon water treatment to minimize those impacts. The existing rule applies only to water pollution and changes in flow. We also propose to revise the existing rule to clarify that this requirement is not absolute and that it applies only to the maximum extent practicable. The addition of a reference to streams and their biota recognizes the importance of those features to the hydrologic balance, watershed ecology, and environmental values related to fish and wildlife. This requirement also would benefit the permittee because using mining and reclamation practices that avoid the creation of discharges requiring treatment is economically advantageous, especially for selenium where recent settlement agreements and court orders have resulted in the construction of treatment plants and implementation of treatment plans that will cost tens of millions of dollars. Proposed paragraph (b)(2) is substantively identical to the last U.S.C. 1265(b)(10). U.S.C. 1265(b)(10)(A). 571 30 U.S.C. 1265(b)(24). sentence of existing 30 CFR 816.41(d)(1). Proposed Paragraph (c) Proposed paragraph (c) is substantively identical to the middle sentence of existing 30 CFR 816.41(a). Proposed Paragraph (d) Proposed paragraph (d) would establish examination and reporting requirements for the surface-runoff control structures identified in the surface-water runoff control plan approved in the permit under proposed 30 CFR 780.29. Section 515(b)(10)(B)(i) of SMCRA,572 which requires that surface coal mining operations be conducted ‘‘so as to prevent, to the extent possible using the best technology currently available, additional contributions of suspended solids to streamflow, or runoff outside the permit area,’’ provides legal authority for adoption of these requirements. In general, hydraulic structures for sediment control are designed to retain surface runoff from the 10-year, 24-hour precipitation event within the permit area and then discharge the retained runoff at a rate that does not exacerbate downstream and off-permit impacts. In other words, by retaining surface runoff on the minesite, peak flow, stream scour, and sediment deposition in receiving streams does not increase beyond the level that would occur in the absence of mining. The structures act as ‘‘flow equalization chambers.’’ Proposed paragraph (d)(1) would require that the permittee examine the entire surface-water control system promptly after the cessation of each precipitation event of a specified size. The size of the precipitation event generating the examination would differ depending on average annual precipitation amounts. For consistency, we propose to use the same average annual precipitation amounts as section 515(b)(20) of SMCRA 573 uses to determine the length of revegetation responsibility periods; i.e., our proposed examination requirements would differ depending on whether the permit lies in an area with average annual precipitation of 26.0 inches or less. Bankfull flow in a stream in an area with an average annual precipitation of more than 26.0 inches generally occurs in response to a precipitation event with a recurrence interval between 1.5 and 2 years. Bankfull flow is the stage at which water in the stream just fills the stream channel to the top of its banks; 569 30 570 30 Jkt 235001 PO 00000 Frm 00110 Fmt 4701 Sfmt 4702 572 30 573 30 E:\FR\FM\27JYP2.SGM U.S.C. 1265(b)(10)(B)(i).

Under natural conditions, any precipitation event greater than the 2-year event would be expected to result in some flooding— and possibly flood-related damage. However, the more modest flows from smaller, more frequent events often transport the greatest quantity of sediment material over time.574 Hydraulic structures for surface coal mining and reclamation operations are typically designed with a combination of sediment and stormwater runoff storage capacity well in excess of the estimated surface runoff from the 2-year event. Failure to maintain these structures by removing accumulated sediment can result in a reduction of stormwater storage capacity, which in turn may result in a discharge that causes property damage or material damage to the hydrologic balance outside the permit area. Therefore, for areas with an average annual precipitation of more than 26.0 inches, proposed paragraph (d)(1)(i) would apply the examination and reporting requirements to all precipitation events that equal or exceed the 2-year recurrence interval. We invite comment on whether a precipitation event with a 2-year recurrence interval is an appropriate threshold for requiring examination of sediment control systems in mesic regions or whether we should allow variations based upon differences in terrain, storm frequency, the nature of sedimentation control structures, and the frequency with which discharges from sedimentation control structures occur. In contrast, our experience indicates that discharges from sedimentation ponds are extremely rare in areas with an average annual precipitation of 26.0 inches or less. A review of representative mines in the West determined that approximately one percent of all impoundments discharge in any single year. Another survey indicated that discharges occurred in only one of the past 10 years. Therefore, for areas with an average annual precipitation of 26.0 inches or less, proposed paragraph (d)(1)(ii) would apply the examination and reporting requirements only to significant precipitation events. The regulatory authority would be responsible for establishing that threshold, either as part of the regulatory program or in the permit. We invite comment on whether we should establish more specific 574 Rosgen, Dave. ‘‘Applied River Morphology.’’ Wildland Hydrology (1996).

Proposed paragraph (d)(2) would require that the permittee prepare a report after the occurrence of each precipitation event that equals or exceeds the applicable threshold. The proposed rule would require that the report discuss the performance of the hydraulic structures, identify and describe any material damage to the hydrologic balance outside the permit area that occurred, and identify and describe the remedial measures taken in response to that damage. The proposed rule also would require that the report be certified by a registered professional engineer and be submitted to the regulatory authority within 48 hours of cessation of the applicable precipitation event to ensure that the regulatory authority has the ability to take prompt action to correct any deficiencies. saturation, groundwater migration rates typically are measured in only feet per day. Therefore, proposed paragraph (a)(2) would require that groundwater monitoring continue through mining and during reclamation until the entire bond amount for the monitored area has been fully released under proposed 30 CFR 800.42(d), which generally will not occur until expiration of the revegetation responsibility period. In addition, proposed 30 CFR 800.42(a) would provide that the regulatory authority may not release any portion of the bond if an evaluation of monitoring data indicates that adverse trends exist that could result in material damage to the hydrologic balance outside the permit area. Any shorter time could result in a failure to detect impacts, given the combination of slow saturation and migration rates. 6. Section 816.35: How must I monitor groundwater? Proposed 30 CFR 816.35 is substantively identical to existing 30 CFR 816.41(c), except as discussed below. Proposed Paragraphs (b) and (c) Proposed paragraphs (b) and (c) are substantively identical to existing 30 CFR 816.41(c)(2). Proposed Paragraph (a) Proposed paragraph (a)(1)(i) is substantively identical to the first sentence of existing 30 CFR 816.41(c)(1). Proposed paragraph (a)(1)(ii) would require adherence to the data collection, analysis, and reporting requirements of proposed 30 CFR 777.13(a) and (b) when conducting groundwater monitoring. This provision would be consistent with section 517(b)(2) of SMCRA, which requires that monitoring data collection and analysis ‘‘be conducted according to standards and procedures set forth by the regulatory authority in order to assure their reliability and validity.’’ Proposed paragraph (a)(2) includes the requirement in existing 30 CFR 816.41(c)(3) that groundwater monitoring proceed through mining and continue during reclamation until bond release. However, we propose to revise the existing language to clarify that monitoring must continue until the entire bond amount for the monitored area has been fully released under proposed 30 CFR 800.42(d), not just partial or Phase I or II bond release. This change is appropriate because the time required to achieve saturation of backfilled areas or underground mine voids typically is measured in years, which means that mining-related impacts on groundwater outside the permit area may not occur until years after completion of mining and land reclamation.

We propose to remove existing 30 CFR 816.41(c)(3)(ii) because it provides that the regulatory authority may approve a permit revision that would allow the cessation of groundwater monitoring based on a finding that monitoring is no longer necessary to achieve the purposes of the monitoring plan. As discussed in the preamble to proposed paragraph (a) above, cessation of monitoring before the entire bond amount for the monitored area has been fully released under proposed 30 CFR 800.42(d) is inappropriate, based on the time required for saturation of the backfill and slow groundwater migration rates. Proposed paragraph (d) would continue to allow the regulatory authority to approve a permit revision to otherwise modify the parameters monitored and the sampling frequency under certain conditions. We invite comment on whether we should establish a minimum sampling frequency or place other restrictions on the regulatory authority’s ability to modify monitoring requirements. However, to supplement the demonstrations required by existing 30 CFR 816.41(c)(3)(i) before the regulatory authority may approve a permit revision of this nature, we propose to add requirements that the permittee demonstrate that future changes in E:\FR\FM\27JYP2.SGM 27JYP2 44546 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules groundwater quantity or quality are unlikely and that the operation has preserved or restored the biological condition of perennial and intermittent streams with base flows originating in whole or in part from groundwater within the permit or adjacent areas. See proposed paragraphs (d)(1) and (2)(iii). The additional criteria are intended to ensure that groundwater monitoring requirements are not reduced or modified prematurely. In addition, we propose to replace the requirement in existing 30 CFR 816.41(c)(3)(i) for a demonstration that the water quantity and quality are suitable to support approved postmining land uses with a requirement for a demonstration that the operation has maintained the availability and quality of groundwater in a manner that can support existing and reasonably foreseeable uses.

We also propose to specify that the regulatory authority must issue a permit revision order under § 774.10(b) when requiring changes to the monitoring plan approved in the permit. Proposed Paragraph (f) Like existing 30 CFR 816.41(c)(4), proposed paragraph (f) would require that the permittee install, maintain, operate, and, when no longer needed, remove all equipment, structures, and other devices used in conjunction with monitoring groundwater. We propose to add cross-references to 30 CFR 816.13 and 816.39, which also contain requirements pertinent to the closure or disposition of monitoring wells. 7. Section 816.36: How must I monitor surface water? Proposed 30 CFR 816.36 is substantively identical to existing 30 CFR 816.41(e), except as discussed below. VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 Proposed Paragraph (a) Proposed paragraph (a)(1)(I) is substantively identical to the first sentence of existing 30 CFR 816.41(e)(1).

This provision would be consistent with section 517(b)(2) of SMCRA, which requires that monitoring data collection and analysis ‘‘be conducted according to standards and procedures set forth by the regulatory authority in order to assure their reliability and validity.’’ Proposed paragraph (a)(2) includes the requirement in existing 30 CFR 816.41(e)(3) that surface-water monitoring proceed through mining and continue during reclamation until bond release. However, we propose to revise the existing language to remove any ambiguity concerning the meaning of ‘‘bond release’’ and clarify that monitoring must continue until the entire bond amount posted for the monitored area has been fully released under proposed 30 CFR 800.42(d), not just partial or Phase I or II bond release. As discussed above in the portion of the preamble concerning proposed 30 CFR 816.35(a), this change is appropriate because the time required to achieve saturation of backfilled areas or underground mine voids typically is measured in years, which means that mining-related impacts on groundwater, and hence surface water fed by groundwater, outside the permit area may not occur until years after the completion of mining and land reclamation. Even after complete saturation, groundwater migration rates typically are measured in only feet per day. Therefore, proposed paragraph (a)(2) would require that surface-water monitoring continue through mining and during reclamation until the entire bond amount posted for the monitored area has been fully released under proposed 30 CFR 800.42(d), which generally will not occur until expiration of the revegetation responsibility period.

We invite comment on whether we should establish a minimum sampling frequency or place other restrictions on the regulatory authority’s ability to modify monitoring requirements. However, as in the similar provision in proposed 30 CFR 816.35 relating to groundwater monitoring, we propose to add requirements that the permittee demonstrate that future changes in surface-water quantity or quality are unlikely and that the operation has preserved or restored the biological condition of perennial and intermittent streams within the permit and adjacent areas. See proposed paragraphs (d)(1) and (2)(iii). The additional criteria are intended to ensure that surface-water monitoring requirements are not reduced or modified prematurely. In addition, we propose to replace the requirement in existing 30 CFR 816.41(e)(3)(i) for a demonstration that the water quantity and quality are suitable to support approved postmining land uses with a requirement for a demonstration that the operation has maintained the availability and quality of surface water in a manner that can support existing and reasonably foreseeable uses and that does not preclude attainment of designated uses under section 101(a) or 303(c) of the Clean Water Act.575 Our 575 33 E:\FR\FM\27JYP2.SGM U.S.C. 1251(a) and 1313(c), respectively. 27JYP2 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules proposed replacement language parallels the terminology of our proposed definition of material damage to the hydrologic balance outside the permit area in 30 CFR 701.5, which also relies upon existing, reasonably foreseeable, and designated uses under section 101(a) or 303(c) of the Clean Water Act. We propose to retain the requirement in the last clause of existing 30 CFR 816.41(e)(3)(i) for a demonstration that the water rights of other users have been protected or replaced. Proposed Paragraph (e) Proposed paragraph (e) corresponds to the second sentence of existing 30 CFR 816.41(e)(1), which provides that the regulatory authority may require additional monitoring when necessary. We propose to modify the existing language to specify that the regulatory authority must require additional monitoring when information available to the regulatory authority indicates that additional monitoring is necessary to protect the hydrologic balance, detect hydrologic changes, or meet other requirements of the regulatory program.

Section 816.37: How must I monitor the biological condition of streams? We propose to add this section to require monitoring of the biological condition of perennial and intermittent streams, consistent with the monitoring plan approved in the permit in accordance with proposed 30 CFR 780.23(c). The proposed rule would require annual monitoring during mining and reclamation until the entire bond amount for the monitored area has been fully released under proposed 30 CFR 800.42(d). The annual frequency is intended to provide sufficient data to evaluate the impacts of mining and reclamation without depleting the stream segment of aquatic life, as more frequent sampling might do. Monitoring would enable the permittee and the regulatory authority to determine whether the predictions in the permit application are accurate and to take timely corrective measures if the VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 predictions turn out to be inaccurate. The proposed monitoring requirements generally parallel the requirements for water monitoring under 30 CFR 816.35 and 8816.36, but in simplified form. 9. Section 816.38: How must I handle acid-forming and toxic-forming materials? Proposed section 816.38 would replace and revise existing 30 CFR 816.41(f), which requires that drainage from acid-forming and toxic-forming materials into surface water and groundwater be avoided by appropriate storage, burial, and treatment practices. We propose to flesh out the existing rule to more completely implement section 515(b)(14) of SMCRA,576 which requires that all acid-forming materials and toxic materials be ‘‘treated or buried and compacted or otherwise disposed of in a manner designed to prevent contamination of ground or surface waters,’’ and section 515(b)(3) of SMCRA,577 which provides that ‘‘overburden or spoil shall be shaped and graded in such a way as to prevent slides, erosion, and water pollution.’’ Proposed 30 CFR 816.38 also would more completely implement section 515(b)(10) of SMCRA,578 which provides that surface coal mining and reclamation operations must be conducted to ‘‘minimize the disturbances to the prevailing hydrologic balance at the mine-site and in associated offsite areas and to the quality and quantity of water in surface and ground water systems both during and after surface coal mining operations and during reclamation by *** avoiding acid or other toxic mine drainage.’’ We propose to revise the introductory text of 30 CFR 816.38 to require that the permittee use the best technology currently available to handle acidforming and toxic-forming materials in a manner that will avoid the creation of acid or toxic mine drainage into surface water and groundwater. The phrase ‘‘best technology currently available’’ does not appear in the sections of SMCRA mentioned above. However, application of this standard to the handling of acid-forming and toxicforming materials is appropriate because section 515(b)(24) of SMCRA 579 requires use of the best technology currently available to minimize adverse impacts on fish, wildlife, and related environmental values. The handling of acid-forming and toxic-forming materials would affect surface-water and PO 00000 576 30 U.S.C. 1265(b)(14).

Proposed paragraphs (a) through (f) contain more specific provisions on how the permittee must implement this requirement. Proposed paragraph (a) would require that the permittee identify potential acid-forming and toxic-forming materials in overburden strata and the stratum immediately below the lowest coal seam to be mined. We invite comment on whether there are generally-accepted tests for potential acid-forming and toxic-forming materials in overburden strata that the final rule should require. Proposed paragraph (a) also would require that the permittee cover exposed coal seams and the stratum immediately beneath the lowest coal seam mined with a layer of compacted material with a hydraulic conductivity at least two orders of magnitude lower than the hydraulic conductivity of the adjacent less-compacted spoil to minimize contact and interaction with water. Covering the coal seam and the underlying stratum with material that has a lower permeability than the adjacent spoil would reduce the amount of water that could either reach or leave the coal seam and underlying stratum. Reduced water transmission will inhibit both the creation and migration of acid or toxic mine drainage. Use of materials with such a great difference in permeability should result in the lowpermeability material behaving as an aquitard. The groundwater and infiltrating surface water should preferentially flow through the surrounding high-permeability material and not through the low-permeability material encapsulating the acid-forming or toxic-forming materials. Proposed paragraph (b) would require that the permittee identify the anticipated postmining groundwater level for all locations at which acidforming or toxic-forming materials are to be placed. This information is critical to a determination of whether the materials will remain in an environment that will prevent formation or migration of acid or toxic mine drainage. Proposed paragraph (c) would require that the permittee selectively handle and place acid-forming and toxicforming materials within the backfill in accordance with the plan approved in the permit, unless the permit allows placement of those materials in an excess spoil fill or a coal mine waste refuse pile. Proposed paragraph (c) identifies three acceptable handling techniques for acid-forming and toxicforming materials to be placed in the E:\FR\FM\27JYP2.SGM 27JYP2 tkelley on DSK3SPTVN1PROD with PROPOSALS2 44548 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules backfill: (1) Complete isolation of acidforming and toxic-forming materials from contact or interaction with surface water or groundwater by surrounding those materials with compacted material with a hydraulic conductivity at least two orders of magnitude lower than the hydraulic conductivity of the adjacent less-compacted spoil; (2) placement of acid-forming and toxic-forming materials in a location below the water table where they will remain fully saturated at all times, provided that the permittee demonstrates, and the regulatory authority finds in writing in the permit, that complete saturation will prevent the formation of acid or toxic leachate; and (3) treatment to neutralize the acid-forming and toxic-forming potential of those materials. The last technique may be used in combination with either of the first two methods. Under the proposed rule, the permittee must use the technique or combination of techniques approved in the permit in accordance with proposed 30 CFR 780.12(d)(4). The permittee must demonstrate and the regulatory authority must confirm that the selected technique will be effective for each parameter of concern. For example, a technique that may be effective in preventing the formation of acid drainage might not be effective in preventing leaching of selenium. The regulatory authority may require that the permittee or permit applicant submit additional information, including fate and transport modeling, if deemed necessary. Isolation of acid-forming and toxicforming materials from contact with groundwater or surface water can be accomplished by completely surrounding those materials with compacted material with a hydraulic conductivity at least two orders of magnitude lower than the hydraulic conductivity of the adjacent lesscompacted spoil to minimize interaction with water. Situations requiring saturation rather than isolation arise most frequently in the relatively flat terrain of coalfields in the Midwest and the West. Saturation may not be suitable for materials with the potential for forming toxic compounds through processes other than pyritic oxidation. Proposed paragraph (d) would allow placement of acid-forming and toxicforming materials in an excess spoil fill or a coal mine waste refuse pile when approved in the permit. The proposed rule would require the use of isolation or treatment or a combination of those techniques whenever the permittee places acid-forming or toxic-forming materials in an excess spoil fill or a coal mine waste refuse pile. The proposed VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 rule would not authorize use of the saturation technique because saturation could jeopardize the stability of the fill or refuse pile. Saturation also could result in discharges with high levels of total dissolved solids, which in turn could adversely impact the biological condition of streams and cause material damage to the hydrologic balance outside the permit area. Alternatively, prohibition of placement of acid-forming or toxicforming materials in an excess spoil fill would provide an additional layer of protection against the development of seeps containing acid or toxic mine drainage. We invite comment on whether we should revise our rule to include such a prohibition. Proposed paragraph (e) would modify the requirements in existing 30 CFR 816.41(f)(1)(ii) for temporary storage of acid-forming and toxic-forming materials to emphasize that storage may be used only when the regulatory authority specifically approves temporary storage as necessary and finds in writing in the permit that the proposed storage method will protect surface water and groundwater by preventing erosion, the formation of polluted runoff, and the infiltration of polluted water into aquifers. The proposed rule would require that the regulatory authority specify a maximum time for temporary storage, which may not exceed the period until burial first becomes feasible. We also propose to add a provision prohibiting temporary storage if doing so would result in a risk of adverse impacts to the biological condition of perennial or intermittent streams. Minimizing the need for, and duration of, temporary storage is critical because the oxidation of pyritic materials continues while the material is exposed. Precipitation may infiltrate and percolate through the pile, which can result in an increase in the concentration of total dissolved solids leaving the site. The weathering products of pyrite oxidation essentially become ‘‘stored acidity,’’ which presents a greater risk to the hydrologic balance if the permanent placement technique ultimately is not successful. Our proposed revisions to the temporary storage requirements for acid-forming and toxic-forming materials would improve implementation of section 515(b)(10) of SMCRA.580 580 30 U.S.C. 1265(b)(10). This provision of SMCRA specifies that surface coal mining and reclamation operations must be conducted to— minimize the disturbances to the prevailing hydrologic balance at the mine-site and in associated offsite areas and to the quality and quantity of water in surface and ground water PO 00000 Frm 00114 Fmt 4701 Sfmt 4702 Proposed paragraph (f) would require that disposal, treatment, and storage practices for acid-forming and toxicforming materials be consistent with other material handling and disposal provisions of the regulatory program. This paragraph is substantively identical to existing 30 CFR 816.41(f)(2). 10. Section 816.40: What responsibility do I have to replace water supplies? Proposed 30 CFR 816.40 would replace and revise existing 30 CFR 816.41(h), which contains performance standards to implement section 717(b) of SMCRA.581 That paragraph of SMCRA provides that— The operator of a surface coal mine shall replace the water supply of an owner of interest in real property who obtains all or part of his supply of water for domestic, agricultural, industrial, or other legitimate use from an underground or surface source where such supply has been affected by contamination, diminution, or interruption proximately resulting from such surface coal mine operation. Proposed 30 CFR 816.40 would further flesh out the requirements of this statutory provision by incorporating paragraphs (a) and (b) of the existing definition of ‘‘replacement of water supply’’ in 30 CFR 701.5. We propose to move those paragraphs to 30 CFR 816.40(a)(2) through (4) because they effectively function as performance standards and are not definitional in nature. We also propose to require adherence to the water supply replacement provisions of proposed 30 CFR 780.22(b) when the permit anticipates that damage to water supplies will occur. Finally, we propose to add the following provisions that would apply when unanticipated damage to a protected water supply occurs: • The permittee would have to provide an emergency temporary water supply within 24 hours of notification of unanticipated damage to a protected water supply. The temporary supply must be adequate in quantity and quality to meet normal household needs. • The permittee would have to develop and submit a plan for a permanent replacement supply to the regulatory authority within 30 days of receiving notice of unanticipated damage. systems both during and after surface coal mining operations and during reclamation by— (A) avoiding acid or other toxic mine drainage by such measures as, but not limited to— (i) preventing or removing water from contact with toxic producing deposits[.] 581 30 U.S.C. 1307(b).

The proposed timeframes for replacement of water supplies for which damage is unanticipated differ somewhat from those set forth in the preamble to the existing definition of ‘‘replacement of water supply’’ in 30 CFR 701.5. That preamble defines prompt replacement as providing an emergency drinking water supply within 48 hours of notification, a temporary water supply hookup within 2 weeks of notification, and a permanent replacement supply within 2 years of notification.582 We propose to replace the timeframes in that preamble with the times set forth in proposed 30 CFR 816.40 as discussed above. The proposed timeframes would better protect society and the environment from the adverse effects of surface coal mining operations, in keeping with the purpose of SMCRA set forth in section 102(a) of the Act.583 11. Section 816.41: Under what conditions may I discharge to an underground mine? Proposed section 816.41 would inlude existing 30 CFR 816.41(i) and add four new requirements that must be met before the regulatory authority may approve a proposed discharge to any type of underground mine. First, proposed paragraph (a)(1)(ii) would require a demonstration that the discharge will be made in a manner that will prevent material damage to the hydrologic balance of the area in which the underground mine receiving the discharge is located. Second, proposed paragraph (a)(1)(iii) would require a demonstration that the discharge will be made in a manner that will not adversely impact the biological condition of perennial or intermittent streams. Third, proposed paragraph (a)(3)(ii) would allow the regulatory authority to approve discharges of water that exceed the effluent limitations for pH and total suspended solids only if available evidence indicates that there is no direct hydrologic connection between the underground mine and other waters and that the discharge would not cause material damage to the hydrologic balance outside the permit area. All three of the proposed revisions discussed above are intended to more fully implement section 510(b)(3) of SMCRA,584 which prohibits approval of a permit application unless the applicant demonstrates, and the regulatory authority finds, that the proposed operation has been designed to prevent material damage to the hydrologic balance outside the permit area. The fourth proposed revision would add paragraph (a)(5), which would require that the permit applicant obtain written permission from the owner of the mine into which the discharge is to be made and provide a copy of that authorization to the regulatory authority. 12. Section 816.42: What are my responsibilities to comply with water quality standards and effluent limitations? We propose to redesignate existing 30 CFR 816.42 as paragraph (a) of this section. We also propose to revise this paragraph by replacing the reference to the effluent limitations in 40 CFR part 434 with a reference to the effluent limitations established in the NPDES permit for the operation. This change would make our regulations consistent with the policy and practice of the EPA, which recognizes only the effluent limitations in the NPDES permit as being enforceable. Proposed paragraph (b) would require that discharges of overburden (including excess spoil), coal mine waste, and other materials into waters of the United States be made in compliance with section 404 of the Clean Water Act 585 and its implementing regulations. While the language would be new, the requirement would not—SMCRA permittees always have been required to comply with the Clean Water Act, as emphasized in section 702(a) of SMCRA,586 which provides that ‘‘[n]othing in this Act shall be construed as superseding, amending, modifying, or repealing’’ the Clean Water Act (33 U.S.C. 1251 et seq.), any rule or regulation adopted under the Clean Water Act, any state laws enacted pursuant to the Clean Water Act, ‘‘or other Federal laws relating to preservation of water quality.’’ We invite comment on whether the provisions of proposed paragraph (b) should be considered informational in nature like the provisions of section 702(a) of SMCRA 587 or whether they should be directly enforceable under SMCRA. Proposed paragraphs (c) through (e) would establish enforceable performance standards requiring proper operation and maintenance of water 582 60 585 33 583 30 FR 16727 (Mar. 31, 1995).

Proposed paragraph (d) would require that the permittee remove precipitates and otherwise maintain all water treatment facilities involving the use of settling ponds or lagoons as necessary to maintain the functionality of the ponds or lagoons. The permittee would be required to dispose of the precipitates removed either in an approved solid waste landfill or in a location within the permit area. Proposed paragraph (e) would require that the permittee operate and maintain water treatment facilities until the regulatory authority authorizes their removal based upon monitoring data demonstrating that influent to the facilities meets all applicable water quality standards and effluent limits without treatment. 13. Section 816.43: How must I construct and maintain diversions and other channels to convey water? We propose to revise this section to reflect plain language principles. In addition, we propose several substantive changes. First, proposed paragraph (a)(3) would require the construction of channels that meet temporary diversion design criteria to convey surface runoff to siltation structures whenever the sedimentation control plan approved in the permit pursuant to 30 CFR 816.45 involves the use of siltation structures. This requirement would not apply if the entire disturbed area would naturally drain to the siltation structure without the construction of channels. Requiring that these channels meet temporary diversion design criteria would minimize the potential for failure and the resulting possibility of offsite impacts. Diversion failures have resulted in subsequent failures of larger structures. For example, in West Virginia in 2003, the failure of a diversion ditch caused erosion and the breaching of a reclaimed impoundment, resulting in a flow of water, slurry, and coarse refuse downstream.

Existing 30 CFR 816.43(a) requires that diversions be designed to minimize adverse impacts to the hydrologic balance within the permit and adjacent areas. Proposed paragraph (a)(4)(ii) would clarify that this provision includes a requirement to minimize adverse impacts to perennial and intermittent streams within that area. Existing 30 CFR 816.43(a) requires that diversions be designed to ‘‘prevent material damage outside the permit area.’’ Proposed paragraph (a)(4)(iii) would revise this language to require that diversions be designed to prevent material damage to the hydrologic balance outside the permit area. The revised language would make this provision consistent with the terminology of 30 CFR 773.15(e) and section 510(b)(3) of SMCRA,589 which require that surface coal mining and reclamation operations be designed to prevent material damage to the hydrologic balance outside the permit area. We propose to combine existing 30 CFR 816.43(a)(2)(ii) and (c)(3) into a new paragraph (a)(5)(ii). Existing paragraph (a)(2)(ii) provides that each diversion and its appurtenant structures must be designed, located, constructed, maintained, and used to provide protection against flooding and resultant damage to life and property. Existing paragraph (c)(3) states that this requirement will be deemed met when the combination of channel, bank, and floodplain configuration is adequate to safely pass the peak runoff of a 2-year, 6-hour precipitation event for a temporary diversion and a 10-year, 6hour precipitation event for a permanent diversion. Proposed paragraph (a)(5)(ii) would replace existing paragraph (a)(2)(ii) with a slightly modified version of existing paragraph (c)(3) because existing paragraph (c)(3) effectively negates existing paragraph (a)(2)(ii). Proposed paragraph (a)(5)(ii) would not contain the reference to floodplain configuration in existing paragraph (c)(3) because use of a floodplain to convey flows from storm runoff is appropriate in naturallyfunctioning streams and in restored streams, but not with temporary or permanent diversions. Proposed paragraph (a)(5)(ii) also would require that each diversion be designed using the appropriate regional NRCS synthetic storm distribution to determine peak flows. The preamble to 589 30 proposed 30 CFR 780.29 explains the rationale for this proposed requirement. Proposed paragraph (a)(5)(iii) would include existing paragraph (a)(2)(iii). We propose to add a reference to runoff outside the permit area to be consistent with the underlying statutory provision in section 515(b)(10)(B)(i) of SMCRA,590 which requires that surface coal mining operations be conducted ‘‘so as to prevent, to the extent possible using the best technology currently available, additional contributions of suspended solids to streamflow, or runoff outside the permit area.’’ The last sentence of existing paragraph (a)(3) and the entirety of existing paragraph (b) contain approval, design, and construction requirements for temporary and permanent diversions of perennial, intermittent, and ephemeral streams. We propose to move the approval and design provisions to 30 CFR 780.28(c) and the construction requirements to 30 CFR 816.57(b) to consolidate requirements concerning activities in, through, or adjacent to streams in those sections. Proposed paragraph (b) would specify that 30 CFR 780.28 and 816.57 contain additional requirements applicable to diversions of perennial and intermittent streams. Lastly, we propose to revise paragraph (c)(1) of the existing rules to limit the scope of paragraph (c), which applies to diversions of miscellaneous flows, to surface-water flows other than perennial and intermittent streams. The existing rule is internally inconsistent in that it specifically includes groundwater discharges, but expressly excludes perennial and intermittent streams. However, any flow resulting from a groundwater discharge would be a perennial or intermittent stream under both the existing and proposed definitions of those terms in 30 CFR 701.5. Therefore, diversions of groundwater discharges would be subject to the stream-channel diversion requirements referenced in proposed paragraph (b) rather than standards for miscellaneous flows under paragraph (c). We invite comment on whether we should revise paragraph (c) to apply the same design events for temporary and permanent diversions of miscellaneous flows as apply to temporary and permanent diversions of perennial and intermittent streams because there is no readily apparent hydrologic reason to apply different standards based on the flow regime of the stream. Instead, it may be more logical to prescribe design events based upon the length of time that the diversion is expected to remain U.S.C. 1260(b)(3).

Similarly, permanent diversions of miscellaneous flows would have to be designed and constructed to safely pass the peak runoff from the 100-year, 6-hour precipitation event rather than the 10year, 6-hour event. We also invite comment on whether we should raise the design event for temporary diversions to the 25-year, 6-hour event to provide an added margin of safety. 14. Section 816.45: What sediment control measures must I use? We propose to remove the second sentence of 30 CFR 816.45(b), which reads as follows: ‘‘The sedimentation storage capacity of practices in and downstream from the disturbed areas shall reflect the degree to which successful mining and reclamation techniques are applied to reduce erosion and control sediment.’’ The meaning of this sentence is unclear, but it appears to be predicated on the assumption that all mines will have a sedimentation pond or other siltation structure located downstream of the disturbed area. That assumption is inconsistent with the court decision remanding former 30 CFR 816.46(b)(2) (1983).591 Furthermore, not all sediment control practices include sedimentation storage capacity. Therefore, we propose to remove this sentence to avoid any conflict with either the court decision or current technology. 15. Section 816.46: What requirements apply to siltation structures? We propose to remove existing paragraph (b)(1) of this section because it duplicates 30 CFR 816.45(a)(1), both of which require use of the best technology currently available to prevent additional contributions of suspended solids to streamflow or runoff outside the permit area to the extent possible. Section 816.45 is the more appropriate location for this provision because section 816.46 covers only siltation structures, whereas section 816.45 encompasses all methods of sediment control. Section 816.45 sets forth various measures and techniques that may constitute the best technology currently available for sediment control, 591 PSMRL II, Round III, 620 F. Supp. 1519, 1566– 1568 (D.D.C. 1985), as discussed at 73 FR 75854 (Dec. 12, 2008). See also 51 FR 41961 (Nov. 20, 1986).

Paragraph (b)(2) of 30 CFR 816.46 and 817.46 (1983) required that all surface drainage from the disturbed area be passed through a siltation structure before leaving the permit area. In essence, that paragraph prescribed siltation structures (sedimentation ponds and other treatment facilities with point-source discharges) as the best technology currently available for sediment control. However, paragraph (b)(2) was struck down upon judicial review because the court found that the preamble to the rulemaking in which it was adopted did not articulate a sufficient basis for the rule under the Administrative Procedure Act. The court stated that the preamble did not adequately discuss the benefits and drawbacks of siltation structures and alternative sediment control methods and did not enable the court ‘‘to discern the path taken by [the Secretary] in responding to commenters’ concerns’’ that siltation structures in the West are not the best technology currently available. See In re: Permanent Surface Mining Regulation Litigation II, Round III, 620 F. Supp. 1519, 1566–1568 (D.D.C. July 15, 1985). On November 20, 1986 (51 FR 41961), we suspended the rules struck down by the court. In a technical rule that corrected various errors in citations, cross-references, and other inadvertent errors, we lifted that suspension and removed paragraph (b)(2) from our regulations on September 29, 2010 (75 FR 60272, 60275). However, on February 14, 2014, the court’s decision in NPCA reinstated the version of 30 CFR 816.46(b) in effect before adoption of the stream buffer zone rule on December 12, 2008. This action had the effect of reinstating the suspension, which we codified in a final rule published on December 22, 2014. See 79 FR 76227–76233. We now propose to lift this suspension, remove paragraph (b)(2) of sections 816.46 and 817.46, and redesignate the remaining paragraphs of those sections accordingly. In addition, we propose to redesignate as paragraph (b)(1) the provision in existing paragraph (b)(3) requiring that the permittee construct siltation structures for an area before initiating any surface mining activities in the area. We also propose to revise this paragraph to clarify that the requirement to construct siltation structures applies only when the approved permit requires the use of siltation structures to achieve the sediment control requirements of 30 CFR 816.45. This revision is needed because, as the courts have recognized, VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 siltation structures are not always the best technology currently available for sediment control.592 Proposed paragraph (b)(2) would retain only the requirement in existing paragraph (b)(3) that the construction of siltation structures be certified by a qualified registered professional engineer or a qualified registered professional land surveyor. Finally, we propose to— • Revise existing paragraph (b)(5), which we propose to redesignate as paragraph (b)(4), to remove the prohibition on removing siltation structures sooner than 2 years after the last augmented seeding. The standard is too inflexible and it is arguably inconsistent with the decision in PSMRL II, Round III discussed above, in which the court held that we had not demonstrated that siltation structures are always the best technology currently available to control sediment in runoff from the minesite. Applying that rationale, the permittee should have the option of using other methods of sediment control in lieu of retaining the siltation structures for 2 years after the last augmented seeding. In addition, the remaining standard in the rule, which prohibits removal of siltation structures until the disturbed area is stabilized and revegetated, is sufficient to ensure an appropriate level of environmental protection. • Revise existing paragraph (b)(6), which we propose to redesignate as paragraph (b)(5), to clarify that the exemption for sedimentation ponds approved by the regulatory authority for retention as permanent impoundments under 30 CFR 816.49(b) is contingent upon meeting the maintenance requirements of 30 CFR 800.42(c)(5). The latter rule implements the statutory provision in section 519(c)(2) of SMCRA 593 establishing bond release requirements for silt dams to be retained as permanent impoundments. • Remove existing paragraph (c)(1)(i), which provides that sedimentation ponds must be used individually or in series. This provision adds nothing meaningful to our regulations because there is no other way in which sedimentation ponds could be used. • Revise existing paragraph (c)(1)(ii), which we propose to redesignate as paragraph (c)(1)(i), to provide that the prohibition on locating sedimentation ponds in stream channels applies to both perennial and intermittent stream channels, not just to perennial stream 592 PSMRL II, Round III, 620 F.

In addition, we propose to clarify that any exceptions to this prohibition must comply with 30 CFR 780.28, which contains the permitting requirements for activities in, through, or adjacent to perennial and intermittent streams, and the performance standards concerning sedimentation control structures in streams in 30 CFR 816.57(c). The statutory basis for these proposed changes is the same as the statutory basis for the stream protection measures proposed in 30 CFR 780.28. • Revise existing paragraph (c)(1)(iii)(H), which we propose to redesignate as paragraph (c)(1)(ii)(H), to replace the prohibition on the use of acid-forming or toxic-forming coal processing waste in the construction of sedimentation ponds with a prohibition on the use of any acid-forming or toxicforming materials in the construction of sedimentation ponds. This change is both appropriate and necessary because coal processing waste is not the only form of acid-forming or toxic-forming materials that could conceivably be used in the construction of sedimentation ponds. The proposed change also would better implement section 515(b)(10)(A)(i) of SMCRA,594 which requires the avoidance of acid or other toxic mine drainage by ‘‘preventing or removing water from contact with toxic producing deposits.’’ 16. Section 816.47: What requirements apply to discharge structures for impoundments? We propose to revise this section by updating the terminology to reflect our 1983 rulemaking in which we introduced the term ‘‘coal mine waste’’ and replaced the term ‘‘coal processing waste dams and embankments’’ with coal mine waste impounding structures. See 48 FR 44006 (Sept. 26, 1983). 17. Section 816.49: What requirements apply to impoundments? We propose to update the hazard classifications and incorporations by reference in existing paragraph (a)(1) of this section to be consistent with those in 30 CFR 780.25, which contains the permitting requirements for impoundments. Specifically we propose to update the incorporation by reference of the NRCS publication ‘‘Earth Dams and Reservoirs,’’ Technical Release No. 60 (210–VI–TR60, October 1985), by replacing the reference to the October 1985 edition with a reference to the superseding July 2005 edition.

Consequently, we propose to delete the ordering information pertinent to the National Technical Information Service and replace it with the URL (Internet address) at which the publication may be reviewed and from which it may be downloaded without charge. We propose to revise our permanent impoundment requirements in paragraph (b) by adding three new criteria for approval of permanent impoundments. Proposed paragraph (b)(7) would require a demonstration that approval of the impoundment would not result in retention of spoil piles or ridges that are inconsistent with the definition of approximate original contour. Proposed paragraph (b)(8) would require a demonstration that approval of the impoundment would not result in the creation of an excess spoil fill elsewhere within the permit area. These two proposed changes are intended to provide a safeguard against the retention of final-cut impoundments and associated spoil ridges that are inconsistent with the requirement in section 515(b)(3) of SMCRA 595 to ‘‘restore the approximate original contour of the land with all highwalls, spoil piles, and depressions eliminated.’’ Proposed paragraph (b)(9) would require a demonstration that the impoundment has been designed with dimensions and other characteristics that would enhance fish and wildlife habitat to the extent that doing so is not inconsistent with the intended use of the impoundment. This provision would improve implementation of section 515(b)(24) of SMCRA,596 which requires use of the best technology currently available to the extent possible to enhance fish, wildlife, and related environmental values where practicable. tkelley on DSK3SPTVN1PROD with PROPOSALS2 18.

Part II of this preamble summarizes both the terrestrial impacts of surface coal mining operations and the impacts of those operations on streams, as documented by scientific studies. Among other things, our proposed rule is intended to prevent or minimize the adverse impacts on fish, wildlife, and related environmental values, including streams, documented in those studies. The authority for our proposed revisions to 30 CFR 816.57 is identical to our authority for the corresponding permitting requirements in proposed 30 CFR 780.28 and is discussed at length in the introductory portion of the preamble to that proposed rule. Proposed Paragraph (a) Existing paragraph (a) provides that ‘‘[n]o land within 100 feet of a perennial or intermittent stream shall be disturbed by surface mining activities, unless the regulatory authority specifically authorizes surface mining activities closer to, or through, such a stream.’’ The rule further specifies that the regulatory authority may provide that authorization only upon finding that the activities will not cause or contribute to the violation of applicable state or federal water quality standards and that they will not adversely affect the water quantity and quality or other environmental resources of the stream. The regulatory authority also must find that if there will be a temporary or permanent stream-channel diversion, it will comply with 30 CFR 816.43, which contains the performance standards for diversions. As described in more detail in Part VI of this preamble, existing paragraph (a) has been subject to differing interpretations over the years. In an effort to provide greater clarity, proposed paragraph (a)(1) would retain only the provision that prohibits disturbance of land within 100 feet of a perennial or intermittent stream without regulatory authority approval. We propose to replace the criteria for regulatory authority approval in the existing rule with new permit application requirements and approval criteria and requirements in 30 CFR 780.28. We also propose to expand protections for perennial and intermittent streams, as discussed below. Proposed paragraph (a)(1) would prohibit the conduct of surface mining activities in or through a perennial or intermittent stream, or that would disturb the surface of land within 100 PO 00000 Frm 00118 Fmt 4701 Sfmt 4702 feet, measured horizontally,597 of a perennial or intermittent stream, unless the regulatory authority authorizes those activities in the permit after making the findings that would be required by proposed 30 CFR 780.28. Part VI of this preamble discusses the history of stream buffer zone rules under SMCRA, all of which have established a minimum buffer zone width of 100 feet on either side of the stream. The preamble to our 1979 rules explains the rationale for that width. See 44 FR 15176–15177 (Mar. 13, 1979). A more recent literature review documents that a vegetative filter strip width of 100 feet generally will attenuate sediment in runoff from disturbed areas.598 Section 515(b)(10)(B)(i) of SMCRA,599 which, in relevant part, requires that surface coal mining operations be conducted ‘‘so as to prevent, to the extent possible using the best technology currently available, additional contributions of suspended solids to streamflow, or runoff outside the permit area,’’ provides the primary statutory authority for the minimum buffer width that we propose to establish in paragraph (a)(1). The prohibition on disturbing the buffer zone also would implement section 515(b)(24) of SMCRA,600 which provides that surface coal mining and reclamation operations must be conducted to minimize disturbances to and adverse impacts on fish, wildlife, and related environmental values to the extent possible using the best technology currently available. Proposed paragraph (a)(2) would reiterate that surface mining activities may be conducted in waters of the United States only if the permittee first obtains all necessary authorizations, certifications, and permits under the Clean Water Act, 33 U.S.C. 1251 et seq. This proposed paragraph is an informational provision that would be consistent with section 702(a) of SMCRA,601 which provides that ‘‘[n]othing in this Act shall be construed as superseding, amending, modifying, or repealing’’ the Clean Water Act, any rule or regulation adopted under the Clean Water Act, or any state laws enacted pursuant to the Clean Water Act.

Permit conditions are directly enforceable under SMCRA. Therefore, addition of the permit condition in proposed 30 CFR 773.17(h) would mean that the SMCRA regulatory authority must take enforcement action if the permittee does not obtain all necessary Clean Water Act authorizations, certifications, and permits before beginning any activity under the SMCRA permit that also requires approval, authorization, or certification under the Clean Water Act. Proposed Paragraph (b) Existing paragraph (b) requires that the permittee mark the buffer zone that is not to be disturbed. We propose to move this provision to 30 CFR 816.11(e), which contains a similar requirement, to consolidate the marking requirement in the signs and markers section. Proposed paragraph (b) would establish requirements specific to mining through or diverting perennial or intermittent streams. Proposed paragraph (b)(1) would require compliance with the design and construction and maintenance plans approved in the permit. Proposed paragraph (b)(2) would require that the permittee restore the hydrological form and ecological function of the stream segment as expeditiously as practicable. In essence, this provision would require that the permittee take timely steps to restore the stream, first by constructing an appropriate channel as soon as surface mining is completed in the area in which the channel is to be located, then by planting appropriate vegetation in the riparian corridor in the first appropriate season following channel construction, followed by whatever other action may be needed to restore the stream’s ecological function. Proposed paragraph (b)(2) does not mean that we anticipate rapid restoration of the ecological function of the stream. We recognize that a considerable amount of time may be needed to accomplish that requirement, particularly if restoration of the ecological function requires establishment of substantial canopy cover. Appendix B of a 2012 EPA publication describes a scenario in which high-gradient stream channels devoid of aquatic life on an abandoned minesite in West Virginia may be VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 restored to biological health in an estimated 10 years.602 This time is roughly consistent with the time required for restoration of low-gradient streams in Illinois and Indiana, as discussed in Part II of this preamble. Other studies suggest that a much longer, as-yet-undetermined length of time may be needed to restore formerly high-quality Appalachian streams to a biological condition comparable to their premining biological condition.603 However, as discussed in connection with proposed paragraph (b)(2)(ii), reestablishment of the premining biological condition is not necessarily required to restore the ecological function of the stream. Proposed paragraph (b)(2)(i) would provide that a restored stream channel or a stream-channel diversion need not exactly replicate the channel morphology that existed before mining, but it must have a channel morphology comparable to the premining form of the affected stream segment in terms of baseline stream pattern, profile, and dimensions, including channel slope, sinuosity, water depth, bankfull depth, bankfull width, width of the flood-prone area, and dominant in-stream substrate. These characteristics are critical to restoration of the premining hydrological form or the ecological function of the stream or both. The proposed paragraph also would use terminology that would improve consistency with corresponding requirements under section 404 of the Clean Water Act. Finally, proposed paragraph (b)(2)(i) would include a clause specifying that, for degraded streams, the enhancement provisions of proposed paragraph (b)(4) would apply in place of the requirement in proposed paragraph (b)(2)(i) for restoration of streams to their premining form. This clause is necessary to ensure that the proposed rule would not require restoration of a degraded stream to its degraded premining form and condition. Proposed paragraph (b)(2)(ii)(A) would specify that a stream flowing through a restored stream channel or a stream-channel diversion must meet the 602 Harman, W., R. Starr, M. Carter, K. Tweedy, M.

Proposed paragraph (b)(2)(ii)(B) would clarify that a stream flowing through a restored stream channel or a stream-channel diversion need not contain precisely the same biota or have the same biological condition as the original stream segment did before mining, but it must have a biological condition that is adequate to support the uses that existed before mining and that would not preclude attainment of the designated uses of the original stream segment under section 101(a) or 303(c) of the Clean Water Act 604 before mining. This provision is intended to allow some change in the species composition of the array of insects, fish, and other aquatic organisms found in a stream flowing through a restored stream channel or stream-channel diversion, provided that the change in species composition would preclude neither any use that existed before mining nor attainment of any designated use before mining. Proposed paragraph (b)(2)(ii)(C) would require that the biological condition of the restored stream be determined using a protocol that meets the requirements of proposed 30 CFR 780.19(e)(2). In effect, it would require use of a scientifically-valid multimetric bioassessment protocol used by agencies responsible for implementing the Clean Water Act, with modifications to meet SMCRA-related needs. At a minimum, the protocol must be based upon the measurement of an appropriate array of aquatic organisms, including benthic macroinvertebrates. It must require identification of benthic macroinvertebrates to the genus level; result in the calculation of index values for both habitat and macroinvertebrates; and provide a correlation of index values to the capability of the stream to support designated uses under section 101(a) or 303(c) of the Clean Water Act, as well as any other existing or reasonably foreseeable uses. We seek comment on the effectiveness of using index scores from bioassessment protocols to ascertain impacts on existing, reasonably foreseeable, or designated uses. We also invite commenters to suggest other approaches that may be equally or more effective. Finally, proposed paragraph (b)(2)(ii)(D) would specify that populations of organisms used to determine the postmining biological condition of the stream segment must be self-sustaining within that segment.

Our proposed performance standards in paragraph (b) would complement our proposed permitting requirements at 30 CFR 780.12(b)(3) (one of the steps in the reclamation timetable is restoration of the form of perennial and intermittent stream segments), 780.12(b)(7) (one of the steps in the reclamation timetable is restoration of the ecological function of perennial and intermittent stream segments), 780.12(h) (the reclamation plan must include a detailed stream restoration plan), 780.28(c) (detailed permit application requirements for mining through or diverting a perennial or intermittent stream segment), and 780.28(e)(2) (the regulatory authority must make a specific written finding before approving mining through or diversion of a perennial or intermittent stream segment). Proposed paragraph (b)(2)(iii)(A) would require that performance bond calculations for the operation include a specific line item for restoration of the ecological function of the stream segment. See also proposed 30 CFR 800.14(b)(2). In addition, proposed paragraph (b)(2)(iii)(B) would require that the permittee post a surety bond, a collateral bond, or a combination of surety and collateral bonds to cover the cost of restoration of the ecological function of the stream segment. A selfbond is not an appropriate mechanism to guarantee restoration of a stream’s ecological function because of the risk that the company may cease to exist during the time required to accomplish that restoration. In addition, a self-bond does not require that the permittee file financial instruments or collateral with the regulatory authority, nor is there any third party obligated to complete the reclamation or pay the amount of the bond if the permittee defaults on reclamation obligations. Proposed paragraph (b)(2)(iii)(C) would require that the permittee demonstrate full restoration of the physical form of the restored stream segment before the site would qualify for final bond release under proposed 30 CFR 800.42(d). Proposed 30 CFR 800.42(b)(1) would define Phase I reclamation as including restoration of the form of perennial and intermittent streams, which means that no bond could be released until the permittee restores the hydrological form of any stream segment within the area to which the bond release application applies. VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 Proposed paragraph (b)(2)(iii)(D) would require that the permittee demonstrate full restoration of the ecological function of the restored stream segment before the site would qualify for final bond release under proposed 30 CFR 800.42(d). Under proposed 30 CFR 800.42(b)(2) and (c)(2), the amount of bond retained following Phase I and II reclamation, respectively, must be sufficient to restore the ecological function of the stream segments that were restored in form as part of Phase I reclamation. Proposed paragraph (b)(3) would specify that, upon completion of construction of a stream-channel diversion or restored stream channel, the permittee must obtain a certification from a qualified registered professional engineer that the stream-channel diversion or restored stream channel meets all construction requirements of this section (except those pertaining to restoration of the ecological function) and is in accordance with the design approved in the permit. A similar requirement appears in existing 30 CFR 816.43(b)(4). We propose to move it to 30 CFR 816.57 to consolidate performance standards for the diversion and restoration of perennial and intermittent streams. We also propose to expand its scope to include restored stream channels because proper construction of those channels is no less important in terms of stability, hydraulic capacity, and ecological restoration than is construction of stream-channel diversions. This certification requirement applies only to the construction of the channel; it does not extend to restoration of ecological function or biological requirements, which may lie beyond the engineer’s sphere of professional competence. Finally, proposed paragraph (b)(4) would provide that if the stream segment to be mined through or diverted is in a degraded condition before mining, the permittee must implement measures to enhance the form and ecological function of the segment as part of the restoration or diversion process. This provision is intended to ensure that stream segments degraded by prior mining or other human activities are improved to the fullest extent possible, not just restored to the condition that existed before the current mining operation. It also would implement section 515(b)(24) of SMCRA,605 which provides that surface coal mining and reclamation operations must ‘‘achieve enhancement’’ of fish, wildlife, and related environmental values where practicable, to the extent PO 00000 possible using the best technology currently available. Nothing in our proposed stream restoration requirements would exempt the permittee from meeting any additional onsite or offsite mitigation requirements that the U.S. Army Corps of Engineers may require under section 404 of the Clean Water Act.606 We invite commenters to— • Identify studies pertinent to restoration of the functions of perennial and intermittent streams, particularly headwaters streams, after mining or similar disturbances. • Weigh in on whether our rule should differentiate between lowgradient and high-gradient streams on the theory that high-gradient streams are more difficult to restore in backfilled areas because of the lack of a competent substrate and the removal of perched aquifers. Proposed Paragraph (c) Proposed paragraph (c)(1) would prohibit the use of perennial or intermittent streams as waste treatment systems to convey surface runoff from the disturbed area to a sedimentation pond. It also would prohibit construction of a sedimentation pond in a perennial or an intermittent stream. Almost all perennial and intermittent streams are of high value to fish and wildlife. Therefore, prohibiting the use of those streams for sedimentation control purposes is consistent with section 515(b)(24) of SMCRA,607 which provides that to the extent possible, surface coal mining and reclamation operations must use the best technology currently available to minimize disturbances to and adverse impacts on fish, wildlife, and related environmental values. Our experience indicates that there are almost always reasonable alternatives to using perennial and intermittent streams as waste treatment systems. However, in steep-slope areas, those alternatives may not have the least overall adverse impact on fish, wildlife, and related environmental values because of the extensive disturbance and excavation that would be needed to construct diversions and sedimentation ponds outside streams in that topography. Therefore, proposed paragraph (c)(2) would exempt excess spoil fills or coal mine waste disposal facilities in steep-slope areas from this prohibition when use of a perennial or intermittent stream segment as a waste treatment system for sediment control and construction of a sedimentation 606 33 605 30 U.S.C. 1265(b)(24).

Proposed paragraph (c)(3) would require that the adverse impacts of using a stream segment as a waste treatment system on fish, wildlife, and related environmental values be minimized by keeping the length of the stream segment used as a waste treatment system as short as possible and, when practicable, maintaining an undisturbed buffer at least 100 feet in width along that segment. The proposed rule would require placement of the sedimentation pond as close to the toe of the excess spoil fill or coal mine waste disposal structure as possible. We also propose to require that the permittee remove the sedimentation pond and restore the hydrological form and ecological function of the stream segment in accordance with proposed paragraph (b)(2) following the completion of construction and revegetation of the fill or coal mine waste disposal structure. Both the 1979 and 1983 versions of our permanent regulatory program regulations prohibit the placement of sedimentation ponds in perennial streams unless approved by the regulatory authority. See 30 CFR 816.46(a)(2) (1979) and 816.46(c)(1)(ii) (1983). However, the preamble to the 1979 rules explains that construction of sedimentation ponds in streams typically is a necessity in steep-slope mining conditions: Sedimentation ponds must be constructed prior to any disturbance of the area to be drained into the pond and as near as possible to the area to be disturbed. [Citation omitted.] Generally, such structures should be located out of perennial streams to facilitate the clearing, removal and abandonment of the pond. Further, locating ponds out of perennial streams avoids the potential that flooding will wash away the pond. However, under design conditions, ponds may be constructed in perennial streams without harm to public safety or the environment. Therefore, the final regulations authorize the regulatory authority to approve construction of ponds in perennial streams on a sitespecific basis to take into account topographic factors. tkelley on DSK3SPTVN1PROD with PROPOSALS2 * * * * * Commenters suggested allowing construction of sedimentation ponds in intermittent and perennial streams. Because of the physical, topographic, or geographical constraints in steep slope mining areas, the valley floor is often the only possible location for a sediment pond. Since the valleys are steep and quite narrow, dams must be high and must be continuous across the entire VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 valley in order to secure the necessary storage. * * * * * The Office recognizes that mining and other forms of construction are presently undertaken in very small perennial streams. Many Soil Conservation Service (SCS) [now the Natural Resources Conservation Service] structures are also located in perennial streams. Accordingly, OSM believes these cases require thorough examination. Therefore, the regulations have been modified to permit construction of sedimentation ponds in perennial streams only with approval by the regulatory authority. 44 FR 15159–15160 (Mar. 13, 1979) (citations omitted). In short, what was true in 1979 remains true today; i.e., sedimentation ponds must be constructed where there is sufficient storage capacity, which, in narrow valleys lacking natural terraces, typically means in the stream. Our proposed rule is consistent with a March 1, 2006, letter from Benjamin Grumbles, Assistant Administrator of the EPA, to John Paul Woodley, Assistant Secretary of the Army (Civil Works). Among other things, that letter states that the sedimentation pond must be constructed as close to the toe of the fill as practicable to minimize temporary adverse environmental impacts associated with construction and operation of the waste treatment system. 19. Section 816.71: How must I dispose of excess spoil? We propose to revise our excess spoil rules to minimize the extent to which excess spoil fills adversely impact perennial and intermittent streams, to improve fill stability, and to enhance fill aesthetics and compatibility with surrounding landforms. As previously discussed in the portions of this preamble concerning 30 CFR 780.35, we propose to move paragraphs (b)(1) (design certification), (c) (location), and (d)(1) (foundation investigations) of the existing version of 30 CFR 816.71 to 30 CFR 780.35 as part of our effort to place provisions that are solely design considerations and requirements in our permitting regulations in subchapter G rather than in the performance standards in subchapter K. Proposed Paragraph (a): General Requirements Both the existing and proposed versions of paragraph (a) require that excess spoil be placed in a controlled manner. However, we propose to revise the introductory language of this paragraph to specifically require that excess spoil be transported and placed by mechanical means. The added PO 00000 Frm 00121 Fmt 4701 Sfmt 4702 44555 language is intended to more fully implement 515(b)(22)(A) of SMCRA,608 which requires that excess spoil be ‘‘transported and placed in a controlled manner in position for concurrent compaction and in such a way to assure mass stability and to prevent mass movement.’’ Our existing rules at 30 CFR 816.73 allow end-dumping of excess spoil down steep slopes into a valley. This practice relies upon gravity transport, rather than mechanical transport, of spoil to its final location. We no longer consider gravity transport of spoil to its final location to be controlled placement under section 515(b)(22)(A) of SMCRA.609 The preamble to our proposed removal of 30 CFR 816.73 explains the shortcomings of end-dumping and durable rock fills in greater detail. However, nothing in the proposed revisions to our excess spoil requirements would prohibit the construction of valley fills, head-ofhollow fills, sidehill fills, or any type of fill other than durable rock fills. We propose to revise existing paragraphs (a)(1) through (3) and add paragraphs (a)(4) through (7) as follows: • Proposed paragraph (a)(1) is substantively identical to existing paragraph (a)(1) except that we propose to add a requirement that excess spoil placement will minimize adverse effects of leachate and surface-water runoff on the biological condition of perennial and intermittent streams within the permit area, not just adverse effects on surface water and groundwater as in the existing rule. The new requirement would implement section 515(b)(24) of SMCRA 610 more fully by minimizing adverse impacts of the operation on fish, wildlife, and related environmental values. • Proposed paragraph (a)(2) is substantively identical to existing paragraph (a)(2). • We propose to revise paragraph (a)(3) to be more consistent with the underlying requirement in section 515(b)(22)(G) of SMCRA,611 which provides that excess spoil must be placed in a manner that will ensure that ‘‘the final configuration is compatible with the natural drainage pattern and surroundings and suitable for intended uses.’’ As revised, proposed paragraph (a)(3) would require that the final surface configuration of the fill be suitable for revegetation and the postmining land use or uses and be compatible with the natural drainage pattern and surroundings.

Our proposed revisions would correct those omissions. • Proposed paragraph (a)(4) would add a requirement that excess spoil be placed in a manner that would minimize disturbances to and adverse impacts on fish, wildlife, and related environmental values to the extent possible, using the best technology currently available. This provision parallels the language of section 515(b)(24) of SMCRA,612 which applies to all aspects of surface coal mining and reclamation operations, including the disposal of excess spoil. • Proposed paragraph (a)(5) would require that excess spoil be placed in a manner that would ensure that the fill will not change the size or frequency of peak flows from precipitation events or thaws in a way that would result in an increase in damage from flooding when compared with the impacts of premining peak flows. • Proposed paragraph (a)(6) would require that excess spoil be placed in a manner that would ensure that the fill will not preclude any existing or reasonably foreseeable use of surface water or groundwater or, for surface water downstream of the fill, preclude attainment of any designated use under section 101(a) or 303(c) of the Clean Water Act.613 The proposed language parallels the terminology in our proposed definition of ‘‘material damage to the hydrologic balance outside the permit area’’ in 30 CFR 701.5, which relies in large measure upon the status of existing, reasonably foreseeable, and designated uses of water. • Proposed paragraph (a)(7) would require that excess spoil be placed in a manner that would ensure that the fill will not cause or contribute to an exceedance of any applicable federal, state, or tribal water quality standards. Proposed paragraphs (a)(5) through (7) would more fully implement sections 510(b)(3) and 515(b)(10) of SMCRA.614 Section 510(b)(3) 615 prohibits approval of a permit application unless the applicant demonstrates and the regulatory authority finds that the proposed operation ‘‘has been designed to prevent material damage to the hydrologic balance outside the permit area.’’ Section 515(b)(10) 616 requires that surface coal mining and reclamation operations be conducted so 612 30 U.S.C. 1265(b)(24).

Proposed Paragraph (b): Stability Requirements We propose to move existing paragraph (b))(1), which pertains to certification of the design for the excess spoil fill and appurtenant structures, to 30 CFR 780.35 as part of our effort to move permitting requirements from the performance standards of subchapter K to the permitting provisions of subchapter G. We propose to redesignate existing paragraph (b)(2) as paragraph (b)(1) and revise it to require that the fill not only be designed to attain a minimum static safety factor of 1.5 as required by the existing rules, but that the fill actually be constructed to attain that safety factor. This change is consistent with section 515(b)(22)(A) of the Act,617 which requires that all excess spoil be placed in a way that ensures mass stability and prevents mass movement. We also propose to redesignate existing paragraph (d)(2), which requires keyway cuts for excess spoil fills built on steep slopes, as paragraph (b)(2). In addition, we propose to replace the term ‘‘keyway cuts’’ with ‘‘bench cuts.’’ The term ‘‘keyway cut’’ is technically a cut beneath a dam that is used to extend low-permeability fill material to, but not into, bedrock. The term ‘‘bench cut’’ is more appropriate here because it refers to cuts into bedrock, not just down to bedrock. Fill construction under steep-slope conditions requires that cuts be made into bedrock, not just down to bedrock, to ensure stability. Therefore, our proposed revisions would provide greater fill stability than the existing regulations. Proposed Paragraph (c): Compliance With Permit We propose to move the fill location requirements of existing paragraph (c) to 30 CFR 780.35 because those requirements pertain primarily to the fill design and thus are more appropriately codified as part of the PO 00000 617 30 U.S.C. 1265(b)(22)(A). Frm 00122 Fmt 4701 Sfmt 4702 permitting provisions of subchapter G. We propose to replace those requirements with a performance standard reminding the permittee that the fill must be constructed in accordance with the design and plans approved in the permit. Proposed paragraph (c) would require that fills be built on the sites selected under section 780.35 in a manner consistent with the designs submitted under those sections and approved as part of the permit. Proposed Paragraph (d): Requirements for Handling of Organic Matter and Soil Materials We propose to move the foundation investigation requirements of existing paragraph (d)(1) to 30 CFR 780.35 to consolidate those provisions with a similar and overlapping foundation investigation requirement in that section. We also propose to redesignate existing paragraph (d)(2) as paragraph (b)(2) as discussed above. We propose to redesignate existing paragraph (e)(1) as new paragraph (d). Proposed paragraph (d) would require that soil and organic matter, including vegetative materials, in the footprint of excess spoil fills be salvaged, stored, and redistributed or otherwise used in a manner consistent with our proposed revisions to 30 CFR 780.12(e) and 816.22. Proposed Paragraph (e): Surface Runoff Control Requirements As discussed above, we propose to redesignate existing paragraph (e)(1) as new paragraph (d). In addition, we propose to redesignate existing paragraphs (e)(2) through (5) as paragraphs (g)(1), (h), (i), and (g)(3), respectively. We propose to redesignate existing 30 CFR 816.72(a) as 30 CFR 816.71(e) and revise it to apply to all fills because control of surface-water runoff from the fill and adjacent areas is critical to the stability of all types of fills, not just valley and head-of-hollow fills. Proposed paragraph (e)(1), like existing 30 CFR 816.72(a), would require that runoff from areas above the fill and runoff from the surface of the fill be directed into stabilized channels designed to meet the requirements of 30 CFR 816.43 and to safely pass the runoff from a 100-year, 6-hour precipitation event. We do not consider surface runoff diversions constructed under proposed 30 CFR 816.71(e)(1) to be streamchannel diversions or restored streams, nor would they qualify as offsetting fish and wildlife enhancement measures under proposed 30 CFR 780.28(d)(2). In proposed paragraph (e)(1)(ii), we propose to add a requirement that those E:\FR\FM\27JYP2.SGM 27JYP2 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules channels be designed using the appropriate regional NRCS synthetic storm distribution. The preamble to proposed 30 CFR 780.29 explains the rationale for this proposed requirement. Like its counterpart in existing 30 CFR 816.72(a), proposed paragraph (e)(2) would prohibit directing uncontrolled surface runoff over the outslope of the fill. Like the existing rule, it also would require that the permittee grade the top surface of a completed fill such that the final slope after settlement will be toward properly designed drainage channels. Proposed Paragraph (f): Control of Water Within the Footprint of the Fill Our proposed revisions to this paragraph focus on underdrain requirements, with particular emphasis on ensuring the use of hard, weatherresistant materials and construction techniques that will promote long-term stability. We propose to require that the underdrain system be designed to carry the anticipated infiltration of water due to precipitation, snowmelt, and water from seeps and springs in the foundation of the disposal area away from the excess spoil fill. This requirement would minimize the phreatic level within the fill. We also propose to require that the underdrain system be protected from material piping, clogging, and contamination by an adequate filter system designed and constructed using current, prudent engineering practices to ensure the longterm functioning of the underdrain system. A long-term functioning filter using natural materials generally requires multiple lifts of material specifically sized, graded, and placed so that the overlying lift is progressively smaller in diameter. Geotextile material may be used for filter construction. Filter construction is vital to providing a long-term functioning underdrain. We propose to prohibit the use of perforated pipe as an alternative to hard, weather-resistant rock for two reasons. First, minor shifts within a fill mass can result in a broken and consequently dysfunctional pipe underdrain, but a rock underdrain of sufficient size is likely to be flexible enough to retain sufficient continuity to transport infiltrated water from the fill. Second, a pipe with small perforations and limited to a single flow-through orifice is more likely to clog than a porous rock underdrain with multiple alternative pathways for water transport. Future changes in local surface-water and groundwater hydrology may result 44557 in water infiltration into the fill in excess of what is anticipated. Therefore, we propose to allow the use of perforated pipe in an underdrain system only for the purpose of enhancing the capability of the underdrain to pass water in excess of the anticipated maximum infiltration. However, the rock underdrain must be capable of transporting the anticipated maximum water infiltration out of the fill independent of the presence of the perforated pipe. In addition, the perforated pipe must be made of materials that are not susceptible to corrosion (not just corrosion-resistant materials as in the existing rules) and sufficiently crush-resistant to withstand pressures at the depth at which the pipe will be buried. Finally, we propose to specify that only hard rock that is resistant to weathering, for example, well-cemented sandstone and massive limestone, and that is not acid-forming or toxic-forming may be used to construct durable rock underdrains.

Section 515(b)(22) of SMCRA 618 and most of the rules implementing that statutory provision focus on the longterm stability of excess spoil fills. Longterm stability is of great importance because the industry does not provide maintenance for fills following final bond release, nor does the regulatory authority monitor fills after final bond release. An effective underdrain system is a critical factor in ensuring fill stability. A functional underdrain system allows water from surface-water infiltration into the fill mass and from seeps and springs in the fill’s foundation to freely pass from the fill. The absence of an effective underdrain can result in the formation of a phreatic surface and the associated potential for destabilization because of increased pore-water pressures within the fill mass.

This in turn depends on the presence of large and interconnected pores or voids between the material particles. For this reason, it is important that the underdrains be composed of large, blocky rock. For an underdrain to function well over the long term, the rock must be resistant to weathering and hard enough to withstand the effects of blasting and conveyance from the blast site to the site at which the underdrain system is being constructed. Rock that is not resistant to weathering effects, i.e., rock that is not ‘‘sound,’’ will disintegrate into fragments too small to act as an effective filter and consequently make the underdrain much less permeable. Historically, the criterion governing whether rock is suitable as underdrain material has been its ‘‘durability.’’ PO 00000 Frm 00123 Fmt 4701 Sfmt 4702 Existing 30 CFR 816.71(f)(3) requires that the rock underdrains of excess spoil fills ‘‘be constructed of durable, nonacid-, nontoxic-forming rock (e.g., natural sand and gravel, sandstone, limestone, or other durable rock) that does not slake in water or degrade to soil material, and which is free of coal, clay or other nondurable material.’’ Similar language appears in existing 30 CFR 816.73(b) for durable rock fills. The durable rock fill construction technique has been the predominant construction method for the last 30 years. Unlike other construction methods, it does not require underdrain construction prior to spoil placement or bottom-to-top spoil placement in thin lifts. Instead, spoil is end-dumped into valleys in a single lift or multiple lifts, during which gravity segregation theoretically forms a freedraining zone of large-sized rock in the lower one-third of the fill. The existing regulations do not specify how the durability of rock is to E:\FR\FM\27JYP2.SGM 27JYP2 44558 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules tkelley on DSK3SPTVN1PROD with PROPOSALS2 be determined. In general, both the mining industry and regulatory authorities have relied upon the slake durability index (SDI) for this purpose. This test involves the placement of oven-dried rock samples in 2 mm wire mesh drums 1/3 immersed in water, which are then rotated at 20 rpm for 10 minutes for two cycles. The weight of the sample remaining in the drum is divided by the weight of the original sample and multiplied by 100 to obtain a percentage. SDI values of 90 percent or more are generally considered durable. OSMRE studies and inspection reports indicated that some of the rock material being used in durable rock fill construction was weak and non-durable despite documentation in the permit that the materials being used were considered durable based on SDI tests. The apparent failure of the SDI tests to adequately distinguish between durable and nondurable rock was attributed to the nature of the test and the behavior of shale and other mudstones as they slake or disintegrate into soil. Frequently, samples with those geologic compositions would turn into loose flakes or mud balls that would not pass through the wire mesh during the test. State and federal regulatory authorities have developed a broad consensus that the SDI test is not adequate for surface coal mining and excess spoil fill construction purposes. In response, we developed and tested an alternative testing protocol and classification system called the ‘‘Strength Durability Classification’’ (Welsh et al., 1991).619 The initial phase of the Strength Durability Classification protocol, the jar-slake test, consists of soaking oven-dried rock samples in water for 24 hours to identify very lowdurability rock by its short-term slaking behavior. Samples with minimal breakdown are then subjected to a second phase of free-swell and pointload tests. The free-swell test entails measuring the swell of an oven-dried sample immersed in water for 4 hours. The degree of swell reflects the amount of water absorbed into the void spaces of the rock. Rocks that absorb more water generally weather more rapidly. The point-load strength test involves placing samples between opposite conical platens that are pressed or 619 Welsh, R.A., Jr., Vallejo, L.E., Lovell, L.W., and Robinson, M.K., 1991, The U.S. Office of Surface Mining (OSM) Proposed Strength-Durability Classification System, in ‘‘Proceedings of Symposium on Detection of and Construction at the Soil/Rock Interface’’ (W.F.

The test is performed on at least 20 samples for statistical validity. After plotting the point-load strength and swell-test data on a graph, the points are compared to two ‘‘zones’’ on the same graph representing the acceptable value ranges for durable rock fill underdrains and more conventional, selectively placed rock underdrains. The Strength Durability Classification protocol has proven to be more discriminating than the SDI, but some critics claim that its durability standards are unrealistically stringent. In 2002, we conducted a study in which we visually estimated the percent of durable rock in 44 durable rock fills under construction and judged whether a discernible underdrain was forming by gravity segregation. Of 44 fills under construction, 28 appeared to have less than 80 percent durable rock and 5 fills showed no visual evidence of having a functioning underdrain. The study found that excess spoil fills in Appalachia generally have been stable, but it recommended improvement in the design, construction, and regulation of fills to ensure long-term stability. One recommendation urged continued work on the development of a more discriminating method for determining rock durability. The study suggested that the amount of sandstone available at a minesite should be one criterion for approving a proposed durable rock fill. It also stated that it might be feasible to develop a quantitative method of assessing gravity-segregated underdrain formation.620 In a 2006 special study, we and the Kentucky Department of Surface Mine Reclamation and Enforcement found that 4 of 29 durable rock fills evaluated had ‘‘questionable’’ underdrains.621 Given the problems with rock durability determination discussed above, application of the SDI or other tests of comparable rigor will not ensure a functioning underdrain in any type of fill. While the SDI can distinguish rocks that will quickly slake or disintegrate into soil material, it does not adequately assess whether they can withstand 620 Office of Surface Mining, ‘‘Long-Term Stability of Valley Fills’’ (2002) in Appendices A, B, and C of ‘‘Draft Programmatic Environmental Impact Statement—Mountaintop Mining/Valley Fills in Appalachia,’’ U.S. Environmental Protection Agency, 2003, EPA 9–03–R–00013, EPA Region 3, Philadelphia, PA, available at https://www.epa.gov/ region3/mtntop/eis2003.htm. 621 Kentucky Department of Natural Resources and U.S. Office of Surface Mining, ‘‘Excess Spoil Fill Stability,’’ Evaluation Year 2006 Special Study, OSM open file report, Lexington, KY, 2006.

Although the Strength Durability Classification protocol is somewhat more discriminatory than the SDI, it also is not sufficiently representative of the short-term and long-term dynamics of a surface mine site. The jar-slake and free-swell tests in particular do not adequately assess the long-term weathering resistance of the rock and the point-load test may not be sufficiently representative of the dynamic effects of blasting, collision, and abrasion. Although there are other classification systems relating to rock durability in the literature, many are designed for rocks unlike those encountered in coal mining. Other protocols apply only to shale, include SDI in addition to other tests or indices, or measure the properties of in-place rock slopes. Therefore, we propose to base the acceptability of rock for use in underdrains on the rock’s hardness and resistance to weathering. Underdrains in a fill constructed in lifts occupy narrow corridors within the fill mass even when properly sized to handle anticipated maximum drainage discharge. Any clogging within these limited zones will quickly engender fill instability. Consequently, criteria for underdrain materials must be selected with the goal of ensuring that the underdrain system will remain effective on a long-term basis, not just until final bond release. Our proposed rule would establish criteria based on rock lithology and the results of two methods that measure the rock’s hardness and soundness via laboratory tests. First, materials used to construct underdrains must consist of hard rock that is resistant to weathering, such as well-cemented sandstone and massive limestone, and that is not acidforming or toxic-forming (and thus would not result in acid or toxic mine drainage). In addition, materials used to construct underdrains must be free of both soil and fine-grained, clastic rocks such as siltstone, shale, mudstone, and claystone, which generally are weaker and more prone to rapid weathering than sandstones and limestone. Finegrained rocks also are problematic in that they produce a fine-grained, impermeable soil when highly weathered. From field observations of durable rock fills under construction, we know that the appearance of shale boulders can be deceptive. Large shale particles that appear competent soon after being end-dumped often quickly disintegrate from natural weathering processes, the stress resulting from being buried at depth, and abrasion E:\FR\FM\27JYP2.SGM 27JYP2 tkelley on DSK3SPTVN1PROD with PROPOSALS2 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules from handling. Even if tests find some shale to be hard and sound enough for underdrain material, the certifying engineer would have difficulty ensuring that all rock placed in the underdrain was correctly selected. Second, the materials must meet certain threshold criteria as determined by the Los Angeles abrasion test and either the sodium sulfate or magnesium sulfate soundness test.622 Highway departments frequently use both tests to assess the suitability of rock for the construction of roads and riprap-lined drainage channels. The Los Angeles abrasion test focuses on rock hardness. It consists of placement of the rock sample in a steel drum containing a prescribed number of steel spheres. After rotating the drum 1,000 times, the sample is removed and sieved. The amount of degradation of the sample is reported as the percent (by weight) of the sample lost through the sieve. The shocks, collisions, and abrasions that the sample experiences are reasonably representative of the dynamics and handling of materials at a minesite. The sodium sulfate and magnesium sulfate soundness tests measure the susceptibility of rock to weathering. In these tests, the rock sample is immersed in a saturated solution of sodium sulfate or magnesium sulfate, after which the sample is placed in an oven to dehydrate the salts, which precipitate in the voids between the rock particles. The process is then repeated on the sample for a specified number of cycles to simulate freezing and thawing. The external expansive force of the salt crystals during the immersion phase of each cycle simulates the expansion of water upon freezing. We acknowledge that freezing of water in rocks and soil does not occur in all climates. Furthermore, its occurrence is limited to a relatively shallow depth below the surface and consequently is not a process that would affect most of the buried underdrain. However, an underdrain is only as good as its weakest point and, like the natural weathering process, this test exploits openings and weaknesses in rock such as fractures and the porous zones of weakly cemented grains. The sulfate soundness tests measure the rock’s ability to withstand repeated freezethaw cycles and thus facilitate identification of those rock materials most likely to remain competent on a long-term basis. 622 See https://www.pavementinteractive.org/ index.php?title=Sulfate_Soundness_Test (last accessed January 19, 2015). VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 Proposed Paragraph (g): Placement of Excess Spoil Proposed paragraph (g)(1) is the counterpart to existing paragraph (e)(2). We propose to move the provision of existing paragraph (e)(2) requiring that the fill be covered with topsoil or other suitable materials to proposed paragraph (d), which contains all requirements related to soils. We also propose to eliminate the provision in existing paragraph (e)(2) that would allow the regulatory authority to approve an exception to the requirement that excess spoil be placed in horizontal lifts of no more than 4 feet in thickness. Placement in lifts exceeding 4 feet in thickness will not uniformly result in the concurrent compaction necessary to minimize the volume of void spaces in the fill. Minimization of the volume of void spaces is critical to minimizing the adverse impact on fish and wildlife because the volume of void spaces correlates directly with the amount of dissolved solids that migrate from the fill into the receiving stream. An increase in dissolved solids can have a substantial adverse impact on aquatic life. Proposed paragraph (g)(1) would require the use of mechanized equipment to transport and place excess spoil. Similarly, proposed paragraph (g)(2) would prohibit the use of any excess spoil transport and placement technique that involves end-dumping, wing-dumping, cast-blasting, gravity placement, or casting spoil downslope, all of which are not conducive to concurrent compaction or placement in lifts no greater than 4 feet in thickness. As noted above, section 515(b)(22)(A) of SMCRA 623 provides that all excess spoil material resulting from surface coal mining operations must be ‘‘transported and placed in a controlled manner in position for concurrent compaction and in such a way to assure mass stability and to prevent mass movement.’’ Our proposed prohibition on the placement of excess spoil in horizontal lifts greater than 4 feet in thickness would improve implementation of this provision of SMCRA, especially the requirements for controlled placement and concurrent compaction. As explained in our discussion of proposed paragraph (a), our existing rules at 30 CFR 816.73 allow end-dumping of excess spoil down steep slopes into a valley. This practice relies upon gravity transport of spoil to its final location. We no longer consider gravity transport of spoil to its final location to be controlled placement under section 515(b)(22)(A) of SMCRA.624 Only mechanical transport meets that statutory requirement. The preamble to our proposed removal of 30 CFR 816.73 explains the shortcomings of end-dumping and durable rock fills in greater detail. Furthermore, we have found that gravity placement in single or large lifts has resulted in elevated suspended solids during storm events because of the flushing of fine material from the loose-dumped excess spoil and from the typically large unvegetated active free face associated with this construction method. Placement in smaller lifts with concurrent compaction would decrease the permeability of the fill, inhibiting infiltration, allowing revegetation of the fill face concurrent with construction of the fill, and reducing discharges of both suspended and dissolved solids. Proposed paragraph (g)(3) is the counterpart to existing paragraph (e)(5). Proposed paragraph (g)(3)(i) would require that acid-forming and toxicforming materials be handled and placed in accordance with 30 CFR 816.38 and in a manner that will minimize adverse effects on plant growth and the approved postmining land use. Under proposed 30 CFR 816.38(d), the only acceptable techniques for the placement of acidforming and toxic-forming materials would be isolation and treatment. The proposed rule would not authorize use of saturation techniques because of the stability risk that saturation poses for fills and because of the possibility that use of saturation techniques would increase discharges of total dissolved solids, which could have adverse impacts on aquatic life in streams that receive those discharges. Proposed paragraph (g)(3)(ii) would require that the permittee cover combustible materials with noncombustible materials in a manner that will prevent sustained combustion and minimize adverse effects on plant growth and the approved postmining land use. Proposed paragraph (g)(3) is consistent with section 515(b)(14) of SMCRA,625 which requires that all acidforming materials and toxic materials be ‘‘treated or buried and compacted or otherwise disposed of in a manner designed to prevent contamination of ground or surface waters’’ and which requires that materials constituting a fire hazard be treated or buried to prevent sustained combustion.

Proposed Paragraph (h): Final Configuration Proposed paragraph (h) is the counterpart to existing paragraph (e)(3), which requires that the final configuration of the fill be suitable for the approved postmining land use. Proposed paragraph (h)(1) would add requirements that the final configuration of the fill be compatible with the natural drainage pattern and the surrounding terrain and, to the extent practicable, consistent with natural landforms. The added provisions would better implement section 515(b)(22)(G) of SMCRA,627 which requires that the final configuration be ‘‘compatible with the natural drainage pattern and surroundings and suitable for intended uses.’’ Proposed paragraph (h)(2) is substantively identical to the provisions of existing paragraph (e)(3) concerning terracing. Proposed paragraph (h)(3)(i) would add a new requirement for the use of geomorphic reclamation principles for the final surface configuration of the fill. Specifically, it would require that the top surface of the fill be graded to create a topography that includes ridgelines and valleys with varied hillslope configurations when practicable, compatible with stability and postmining land use considerations, and generally consistent with the premining topography. Geomorphic reclamation principles are intended to produce a final surface configuration with greater erosional stability and more ecological benefits than other techniques. Proposed paragraph (h)(3)(ii) would allow the final surface elevation of the fill to exceed the elevation of the surrounding terrain when necessary to minimize placement of excess spoil in perennial and intermittent streams, provided the final configuration complies with the compatibility and postmining land use requirements of proposed paragraphs (a)(3) and (h)(1). Sections 515(b)(10)(B)(i) and 515(b)(24) of SMCRA provide the primary statutory authority for proposed paragraphs (h)(3)(i) and (ii). Section 515(b)(10)(B)(i) of SMCRA 628 requires that surface coal mining operations be conducted to prevent, to the extent possible using the best technology currently available, additional contributions of suspended solids to streamflow or runoff outside the permit area. Section 515(b)(24) of SMCRA 629 requires that, to the extent possible using the best technology currently available, surface coal mining and reclamation operations be conducted so as to minimize disturbances and adverse impacts of the operation on fish, wildlife, and related environmental values and to achieve enhancement of those resources where practicable. Finally, we propose to add paragraph (h)(3)(iii), which would provide that the geomorphic reclamation requirements of paragraph (h)(3)(i) do not apply in situations in which they would result in burial of a greater length of perennial or intermittent streams than traditional fill design and construction techniques. Allowing use of reclamation techniques that would bury a greater length of stream than other techniques would not be consistent with section 515(b)(24) of SMCRA as discussed above. Proposed Paragraph (i): Impoundments and Depressions Proposed paragraph (i) is the counterpart to existing paragraph (e)(4), which prohibits the construction of permanent impoundments on the completed fill and establishes criteria for the construction of small depressions on the surface of the fill. The proposed rule is substantively identical to the existing rule with the exception that we propose to further restrict the conditions under which small depressions may be constructed or retained on the completed fill. Specifically, we propose to allow small depressions only when they are consistent with the hydrologic reclamation plan approved in the permit in accordance with 30 CFR 780.22 and when infiltration resulting from those depressions would not result in elevated levels of parameters of concern (especially sulfate and other ions that increase specific conductance and electrical conductivity in streams) in discharges from the fill. The proposed revisions would assist in ensuring that discharges from the fill will not cause material damage to the hydrologic balance outside the permit area, in compliance with section 510(b)(3) of SMCRA.630 It also would minimize ‘‘disturbances to the prevailing hydrologic balance at the mine-site and in associated offsite areas and to the quality and quantity of water in surface and ground water systems’’ as required by section 515(b)(10) of SMCRA.631 629 30 U.S.C. 1265(b)(24).

Proposed Paragraph (k): Inspections and Examinations Proposed paragraph (k) is the counterpart to existing paragraph (h), which establishes inspection requirements for excess spoil fills. We propose to revise the professional inspection requirements for excess spoil fills by specifying that the engineer or other specialist must conduct additional complete inspections during critical construction periods to ensure that the fill is constructed properly. Proposed paragraphs (k)(2)(i) and (ii) would require that the engineer or specialist conduct daily examinations during placement and compaction of fill materials and maintain a log of those examinations. Proposed paragraph (k)(3)(iii) would require that the certified report that the engineer or specialist submits for each complete inspection include a review and summary of the daily examination logs. If the report identifies any evidence of instability, structural weakness, or other hazardous conditions, proposed paragraph (k)(3)(ii) would require that the permittee submit an application for a permit revision that includes appropriate remedial design specifications. The proposed revisions are intended to ensure that excess spoil fills are constructed in compliance with the stability requirements of section 515(b)(22) of SMCRA.632 Placement of the underdrain and the placement of the filter are each considered critical construction phases. Therefore, two separate inspections are required if the underdrain is constructed first and the filter system is constructed later. However, these two phases can be concurrent, in which case one inspection may suffice for both phases. We invite comment on whether the rule should require additional specific oversight by the engineer when segregated, graded, natural material is used to construct the filter system. Finally, we propose to remove existing paragraph (h)(3)(ii), which pertains to durable rock fills constructed under 30 CFR 816.73, consistent with our proposal to prohibit that method of fill construction.

Why are we proposing to remove the provisions for rock-core chimney drains in existing 30 CFR 816.72(b)? We propose to remove existing 30 CFR 816.72(b) because mine operators are no longer constructing fills with rock-core chimney drains. A rock-core chimney drain is a vertical column of durable rock extending from the toe of the fill to the head of the fill and from the base of the fill to the surface of the fill. A few small fills constructed decades ago included rock-core chimney drains, but, to the best of our knowledge, the technique has not been used recently or on large fills. Our proposed removal of 30 CFR 816.72(b) would not prohibit the construction of head-of-hollow or valley fills without rock-core chimney drains. However, all proposed head-of-hollow and valley fills would have to meet the permitting requirements of proposed 30 CFR 780.28 and 780.35. If approved, these fills would have to comply with the performance standards of proposed 30 CFR 816.71. 633 30 21. Why are we proposing to remove the provisions for durable rock fills in existing 30 CFR 816.73? Existing 30 CFR 816.73 allows excess spoil fills to be constructed by enddumping, in which overburden is pushed or dumped over the side of the mountain to cascade into the valley below. In theory, the larger rocks roll to the bottom of the valley to form an underdrain by gravity segregation. We propose to remove this section for four reasons. First, further scrutiny of the statutory provisions governing disposal of excess spoil indicates that this method of fill construction does not comply fully with section 515(b)(22)(A) of SMCRA.634 That provision of SMCRA requires that surface coal mining and reclamation operations place all excess spoil material in such a manner that the ‘‘spoil is transported and placed in a controlled manner in position for concurrent compaction and in such a way [as] to assure mass stability and to prevent mass movement.’’ End-dumping of excess spoil relies upon gravity both for transport after dumping and to determine final placement, which does not comport well with the statutory requirement for transport and placement in a controlled manner. Second, as discussed in the preamble to proposed 30 CFR 816.71(f), we have observed inconsistent formation of underdrains in durable rock fills. Nonfunctional underdrains may compromise the stability of the fill by raising the moisture content of the fill material, which increases the ability of that material to move. Saturated fills are prone to buckling and landslides. Third, as discussed in detail below, durable rock fills may increase the risk of flooding and associated damage because of the large size of the fill face and the length of time that the face remains unvegetated. Fourth, the lack of compaction during the construction of durable rock fills creates the potential for increased levels of total dissolved solids in discharges from those fills because of the greater amount of pore space and reactive surface compared with other types of fills. Higher levels of total dissolved solids in discharges from the fill translate to elevated electrical conductivity in streams downgradient of the fill. As summarized in Part II of this preamble, elevated electrical conductivity can adversely impact the capability of the stream to support certain species of benthic macroinvertebrates, which in turn reduces the capability of the stream to U.S.C. 1260(b)(3) and 1265(b)(10).

Therefore, we propose to refine our existing regulations by removing 30 CFR 816.73, which allows construction of durable rock fills by gravity transport and placement. With respect to other types of excess spoil fills, proposed 30 CFR 816.71(g) would require use of mechanized equipment to transport and place the excess spoil in lifts no greater than 4 feet, which would greatly increase both control and compaction. Increased compaction of the spoil placed in the fill would increase the density of each unit of excess spoil and thus decrease the amount of space that it occupies. The resulting reduction in the amount of spoil storage space needed would (or at least could) reduce the footprint of the fill, which should reduce the number and length of stream segments buried by the fill. Increased compaction also should reduce discharges of total dissolved solids and other parameters of concern, thus minimizing the adverse impacts on fish, wildlife, and related environmental values as required by section 515(b)(24) of the Act.635 Finally, construction of fills using mechanized methods of transport and placement would facilitate the special handling of acidforming and toxic-forming materials, which should result in a reduction in the concentration and volume of toxic materials, such as selenium, in water discharged from the fill, which would further minimize adverse impacts on fish, wildlife, and related environmental values. As mentioned above, some durable rock fills have exacerbated flooding during and after precipitation events. Flooding may threaten public safety and cause property damage downstream of the fill. The following case studies describe how durable rock fills may contribute to flooding and damage from flooding. Snap Creek, West Virginia On June 13, 2010, an area near the town of Man in Logan County, West Virginia, received approximately 4.8 inches of rain within 24 hours. Floodrelated damage occurred downstream from an end-dumped durable rock fill on the Snap Creek minesite (Permit S– 5013–96) south of Man. Stormwater runoff flowing down the face of the fill completely filled the sedimentation pond near the toe of the fill. The sediment-laden runoff then scoured the flood plain of the Left Fork of Rich Creek down to bedrock for a distance of 635 30 E:\FR\FM\27JYP2.SGM U.S.C. 1265(b)(24). 27JYP2 44562 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules approximately 0.25 mile. The scoured material, along with spoil from the face of the fill, was deposited on the flood plain and along the stream channel for an additional 0.25 mile to its confluence with Rich Creek. Sedimentation continued along Rich Creek approximately 0.25 mile further to the stream’s confluence with the Guyandotte River. No one was injured and little property damage occurred because most of the affected areas were uninhabited. The fill was being graded to its final configuration when the rainfall event occurred. The finer fractions of the soil exposed on the face of an end-dumped fill during final grading are very susceptible to erosion, particularly during heavy rainfall events. Protecting downstream areas from this type of mudflow at this stage of fill construction is nearly impossible, which provides additional justification for prohibiting the construction of durable rock fills. tkelley on DSK3SPTVN1PROD with PROPOSALS2 Kayford South, West Virginia On June 13, 2010, a significant rainfall event occurred near the town of Dorothy in Raleigh County, West Virginia, resulting in flooding, erosion, and deposition of eroded mine spoil downstream from a durable rock fill associated with a surface mine (Permit S–3008–00). The event eroded the face of the fill, which was being graded for reclamation, with the sediment completely filling the sedimentation pond below the toe of the fill. After filling the pond, water and mobilized sediment flowed down Gardner Branch approximately 0.5 mile to the confluence with the Clear Fork of the Coal River. The flow scoured the stream channel and deposited sediment along the length of Gardner Branch. In this case, no one was injured and little property damage occurred because the affected areas were uninhabited. The fill was being graded to its final configuration when the rainfall event occurred. A primary issue at this site and other durable rock fills is the time lag between completion of excess spoil placement and final grading because of the top-down construction method. In this case, the lag was more than 2 years. During this time, the face of the fill was completely exposed and susceptible to erosion. Lyburn, West Virginia On July 19, 2002, a flood event on Winding Shoals Branch in Lyburn, Logan County, West Virginia, destroyed ten residences and damaged vehicles and property. Stormwater runoff, rock, mud, and debris from a surface mine (Permit S–5023–93) flooded the narrow VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 stream valley. The primary cause of the significant damage at Lyburn was the condition of the durable rock fill and its proximity to structures. At the time of the storm, the company was reclaiming this end-dumped fill. As is typical of an end-dumped durable rock fill during reclamation, soil and small rock particles on the face of the fill were exposed and highly susceptible to erosion. Our proposal to remove 30 CFR 816.73 and the authority that it provides to construct durable rock fills using enddumping and gravity segregation is intended to prevent the recurrence of events like those discussed above. Fills constructed from the bottom up in accordance with 30 CFR 816.71 are much less susceptible to erosion and much less likely to contribute to flooding than are durable rock fills, which are constructed from the top down. The faces of fills constructed in accordance with 30 CFR 816.71 can be reclaimed and revegetated in stages, which reduces surface runoff and susceptibility to erosion, while the faces of durable rock fills cannot be reclaimed and revegetated until the fill is completed. 22. Section 816.74: What special requirements apply to the disposal of excess spoil on a preexisting bench? We propose to revise 30 CFR 816.74(a) to clarify that the term ‘‘preexisting bench’’ applies only to features located on previously mined areas or on bond forfeiture sites. This term does not apply to benches created as part of an earlier phase of the mining operation that generated the excess spoil to be disposed of under this provision. We propose to revise 30 CFR 816.74(b) for consistency with our proposed changes to 30 CFR 780.12(e) and 816.22 concerning the removal, salvage, storage, and redistribution of soil and organic matter. We propose to revise 30 CFR 816.74(c) by adding a requirement that underdrains comply with proposed 30 CFR 816.71(f)(3). In addition, proposed 30 CFR 816.74(e)(2), which is the counterpart to existing 30 CFR 816.74(d)(2), would require the use of all reasonably available spoil to eliminate all preexisting highwalls, consistent with the regulations governing backfilling and grading of previously mined areas under 30 CFR 816.106. Finally, we propose to remove the gravity-transport provisions in 30 CFR 816.74(h) because this method of transporting spoil from one bench to another is not fully consistent with PO 00000 Frm 00128 Fmt 4701 Sfmt 4702 section 515(b)(22)(A) of SMCRA,636 which provides that all excess spoil material resulting from surface coal mining operations must be ‘‘transported and placed in a controlled manner in position for concurrent compaction and in such a way to assure mass stability and to prevent mass movement.’’ Gravity transport is not transport in a controlled manner. 23. Section 816.81: How must I dispose of coal mine waste? Proposed Paragraph (a): General Requirements Proposed paragraph (a) is substantively identical to the first sentence of existing paragraph (a), except that we propose to add language requiring compliance with the refuse pile requirements of 30 CFR 816.83 and the coal mine waste impounding structure requirements of 30 CFR 816.84 when applicable. Proposed Paragraph (b): Basic Performance Standards Proposed paragraph (b) would include the remaining provisions of existing paragraph (a). Proposed paragraph (b)(1) would revise existing paragraph (a)(1) to require that the coal mine waste disposal facility minimize adverse effects not only on the quality and quantity of surface water and groundwater as in the existing rule, but also on the biological condition of perennial and intermittent streams within the permit area to the extent possible, using the best technology currently available. Our proposed revisions are consistent with section 515(b)(24) of SMCRA,637 which requires that, to the extent possible using the best technology currently available, surface coal mining and reclamation operations be conducted so as to minimize disturbances and adverse impacts of the operation on fish, wildlife, and related environmental values and to achieve enhancement of those resources where practicable. We propose to add paragraph (b)(6), which would require that the coal mine waste disposal facility not change the size or frequency of peak flows from precipitation events or thaws in a way that would result in increased damage from flooding when compared with the impacts of premining peak flows. We also propose to add paragraph (b)(7), which would require that the coal mine waste disposal facility not preclude any existing or reasonably foreseeable use of surface water or groundwater or, for surface wates downstream of the 636 30 637 30 E:\FR\FM\27JYP2.SGM U.S.C. 1265(b)(22)(A).

In addition, we propose to add paragraph (b)(8), which would require that the coal mine waste disposal facility not cause or contribute to an exceedance of any applicable water quality standards. Finally, we propose to add paragraph (b)(9), which would require that the disposal facility not discharge acid or toxic mine drainage. The proposed addition of paragraphs (b)(6) through (9) is intended to improve implementation of sections 510(b)(3) and 515(b)(10) of SMCRA. Section 510(b)(3) 639 prohibits approval of a permit application unless the applicant demonstrates and the regulatory authority finds that the proposed operation ‘‘has been designed to prevent material damage to the hydrologic balance outside the permit area.’’ Section 515(b)(10) 640 requires that surface coal mining and reclamation operations be conducted so as to ‘‘minimize disturbances to the prevailing hydrologic balance at the mine-site and in associated offsite areas and to the quality and quantity of water in surface and ground water systems both during and after surface coal mining operations and during reclamation.’’ The proposed revisions also are consistent with our proposed definition of ‘‘material damage to the hydrologic balance outside the permit area’’ in 30 CFR 701.5, which focuses on mining-related impacts to uses of groundwater and surface water. Finally, the proposed revisions are consistent with section 702(a) of SMCRA,641 which provides that nothing in SMCRA may be construed as superseding, amending, modifying, or repealing the Clean Water Act or state laws enacted pursuant to the Clean Water Act. tkelley on DSK3SPTVN1PROD with PROPOSALS2 Proposed Paragraph (c): Coal Mine Waste From Outside the Permit Area Proposed paragraph (c) is substantively identical to existing paragraph (b). 638 33 U.S.C. 1251(a) and 1313(c), respectively. 639 30 U.S.C. 1260(b)(3). 640 30 U.S.C. 1265(b)(10). 641 30 U.S.C. 1292(a). VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 Proposed Paragraph (d): Design and Construction Requirements Proposed paragraph (d) would include existing paragraph (c) in revised form. Proposed paragraph (d)((1)(i) would require that coal mine waste disposal facilities be constructed in accordance with current, prudent engineering practices and any criteria established by the regulatory authority. The existing regulations require that the design of the facility meet those requirements, but they do not address the construction process, which also is important in ensuring that the structure is stable and performs as intended. Proposed paragraph (d)(1)(ii) would require that, as part of the design certification, the engineer specifically certify that any existing and planned underground mine workings in the vicinity of the disposal facility will not adversely impact the stability of the structure. The Martin County Slurry Spill incident in Martin County, Kentucky on October 11, 2000, illustrates the magnitude of environmental damage that can result when impounded coal refuse slurry breaks through into adjacent underground mine workings that open to the surface. In this case, the mine openings discharged 306 million gallons of slurry into two tributaries of the Tug Fork River (Coldwater Fork and Wolf Creek). The slurry covered nearby residents’ yards to a depth of as much as 5 feet, visibly polluted more than 100 miles of waterways, including the Big Sandy and Ohio Rivers, and devastated aquatic life in 70 miles of stream. Six public water intakes were adversely affected and alternative water supplies had to be arranged for 27,000 residents. Cleanup costs were approximately $59 million.642 Proposed paragraph (d)(1)(ii) is intended to ensure that each coal mine waste disposal facility is designed to prevent similar events. This design requirement would benefit the public, the environment, and mine operators by reducing the probability of breakthroughs into underground mine workings and the environmental and property damage and cleanup expenses that may result from those breakthroughs. Proposed paragraph (d)(1)(iii) would require that the coal mine waste disposal facility be constructed in accordance with the design and plans 642 See https://www.sourcewatch.org/ index.php?title=Martin_County_sludge_spill (last accessed February 4, 2015) and https:// www.jackspadaro.com/news_articles/2003/10_12_ 03/herald-leader10_12_03.html (last accessed February 4, 2015). PO 00000 Frm 00129 Fmt 4701 Sfmt 4702 44563 submitted under 30 CFR 780.25 and approved in the permit and that a qualified registered professional engineer experienced in the design and construction of similar earth and waste structures certify that the facility has been constructed in accordance with the approved design. Proposed paragraph (d)(1)(iii) would provide additional safeguards for protection of the environment, public health and safety, and property. Thus, it would better implement section 102(a) of SMCRA,643 which states that one of the purposes of SMCRA is to ‘‘establish a nationwide program to protect society and the environment from the adverse effects of surface coal mining operations.’’ To the extent that proposed paragraph (d)(1)(iii) would improve stability, it also would improve implementation of section 515(b)(11) of SMCRA,644 which requires that all waste piles be stabilized in designated areas, and sections 515(b)(13) and 515(f) of SMCRA,645 which include provisions intended to ensure that coal mine waste impoundments are constructed in a manner that would protect public safety and public and private property. And the proposed revisions would be consistent with section 515(b)(23) of SMCRA,646 which requires surface coal mining and reclamation operations to ‘‘meet such other criteria as are necessary to achieve reclamation in accordance with the purposes of this Act, taking into consideration the physical, climatological, and other characteristics of the site.’’ Proposed Paragraph (e): Foundation Investigations Proposed paragraph (e) is substantively identical to existing paragraph (d), except that we propose to add language requiring that the analysis of foundation conditions for the coal mine waste disposal facility take into consideration the effect of any underground mine workings located in either the permit area or the adjacent area. The rationale for this proposed change is the same as the rationale for proposed paragraph (d), as discussed above. Proposed Paragraph (f): Soil Handling Requirements Proposed paragraph (f) would require that vegetation, organic matter, and soil materials be salvaged, stored, and redistributed or otherwise handled in accordance with proposed 30 CFR 643 30 U.S.C. 1202(a). U.S.C. 1265(b)(11). 645 30 U.S.C. 1265(b)(13) and (f). 646 30 U.S.C. 1265(b)(23). 644 30 E:\FR\FM\27JYP2.SGM 27JYP2 44564 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules 816.22. While 30 CFR 816.22 would apply in the absence of this rule, the addition of this paragraph would reaffirm the applicability of that rule to coal mine waste disposal facilities. tkelley on DSK3SPTVN1PROD with PROPOSALS2 Proposed paragraphs (g) and (h): Emergency Procedures and Underground Disposal Proposed paragraphs (g) and (h) are substantively identical to existing paragraphs (e) and (f), respectively. 24. Section 816.83: What special performance standards apply to coal mine waste refuse piles? Proposed 30 CFR 816.83 is substantively identical to existing 30 CFR 816.83 except as discussed below. We propose to revise paragraph (b), which includes existing paragraph (a), to specify that the refuse pile must be constructed with the diversions and underdrains included in the approved design. In proposed paragraph (b)(3), which corresponds to part of existing paragraph (a)(2), we propose to add a requirement that diversion channels be designed using the appropriate regional NRCS synthetic storm distribution to determine the peak flow from surface runoff from a 100-year, 6-hour precipitation event. The preamble to proposed 30 CFR 780.29 explains the rationale for this proposed requirement. We propose to remove existing paragraph (c)(1) because it duplicates the soil handling requirements of proposed 30 CFR 816.81, which 30 CFR 816.83(a) cross-references. In proposed paragraph (d)(2), which corresponds to existing paragraph (c)(3), we propose to delete language in the existing rule that allows the creation and retention of small depressions on the completed refuse pile. Removal of this provision is justified because depressions promote infiltration and because discharges filtered through coal mine waste typically contain higher levels of total dissolved solids, metals, and other parameters of concern than discharges filtered through mine spoil. The proposed revision would improve implementation of sections 510(b)(3) and 515(b)(10) of SMCRA.647 Section 510(b)(3) 648 prohibits approval of a permit application unless the applicant demonstrates and the regulatory authority finds that the proposed operation ‘‘has been designed to prevent material damage to the hydrologic balance outside the permit area.’’ Section 515(b)(10) 649 requires that 647 30 U.S.C. 1260(b)(3) and 1265(b)(10). U.S.C. 1260(b)(3). 649 30 U.S.C. 1265(b)(10). surface coal mining and reclamation operations be conducted so as to ‘‘minimize disturbances to the prevailing hydrologic balance at the mine-site and in associated offsite areas and to the quality and quantity of water in surface and ground water systems both during and after surface coal mining operations and during reclamation.’’ In proposed paragraph (e), which corresponds to existing paragraph (d), we propose to delete the existing inspection standards and requirements and replace them with a cross-reference to the corresponding inspection and examination requirements for excess spoil fills that we propose to adopt as part of 30 CFR 816.71. Excess spoil fills and coal mine waste refuse piles are similar structures in terms of engineering needs and requirements. Therefore, they should have identical inspection and examination requirements. 25. Section 816.84: What special requirements apply to coal mine waste impounding structures? Proposed 30 CFR 816.84 is substantively identical to existing 30 CFR 816.84 except as discussed below. Proposed paragraph (b), which is the counterpart to existing paragraph (a), would clarify that coal mine waste may not be used to construct impounding structures unless the use of coal mine waste will not result acid drainage or toxic seepage through the impounding structure. The existing rule only refers to acid seepage. Our proposed revision of the scope of this rule to include toxic seepage is appropriate because section 515(b)(10)(A) of SMCRA 650 requires avoidance of ‘‘acid or other toxic mine drainage.’’ We also propose to replace the term ‘‘acid seepage’’ in the existing rule with ‘‘acid drainage’’ because that is the term that we define in 30 CFR 701.5. However, we propose to use the term toxic seepage in recognition of the mechanism by which we anticipate that any toxic mine drainage might develop. Proposed paragraph (e), which is the counterpart to existing paragraph (d), would specify that diversions must be both designed and constructed to meet the requirements of 30 CFR 816.43. The existing rule contains only the design requirement. The performance standards of 30 CFR 816.43 apply to all diversions subject to regulation under SMCRA and our proposed revision would reiterate that principle. We also propose to specify that the diversions must be designed using the appropriate regional NRCS synthetic storm 648 30 VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 distribution to determine the peak flow from surface runoff from a 100-year, 6hour precipitation event. The preamble to proposed 30 CFR 780.29 explains the rationale for this proposed requirement. Finally, we propose to move existing paragraph (e) to 30 CFR 780.25(d) because it is a permitting requirement rather than a performance standard. Our goal is to move permitting requirements now located in the performance standards of subchapter K to the permitting provisions of subchapter G whenever feasible. 26. Section 816.95: How must I protect surface areas from wind and water erosion? We propose to revise 30 CFR 816.95(b) to replace the references to topsoil with references to soil and soil substitutes to be consistent with 30 CFR 780.12(e) and 816.22(c), which allow the use of topsoil and subsoil substitutes and supplements under certain conditions. 27. Section 816.97: How must I protect and enhance fish, wildlife, and related environmental values? Unless otherwise noted, our proposed substantive revisions to 30 CFR 816.97, as discussed below, are intended to more fully implement section 515(b)(24) of SMCRA,651 which provides that ‘‘to the extent possible using the best technology currently available’’ surface coal mining and reclamation operations must be conducted so as to ‘‘minimize disturbances and adverse impacts of the operation on fish, wildlife, and related environmental values, and achieve enhancement of such resources where practicable.’’ A few of the proposed revisions also would provide more detail on the measures and procedures needed to ensure compliance with the Endangered Species Act. Proposed requirements for the use of native species and reforestation would more completely implement section 515(b)(19) of SMCRA,652 which requires establishment of a ‘‘permanent vegetative cover of the same seasonal variety native to the area of land to be affected and capable of self-regeneration and plant succession.’’ Proposed Paragraph (a): General Requirements Proposed paragraph (a) would require that the permittee, to the extent possible using the best technology currently available, minimize disturbances and adverse impacts on fish, wildlife, and related environmental values and 651 30 650 30 PO 00000 U.S.C. 1265(b)(10)(A).

Proposed paragraph (a) is substantively identical to both section 515(b)(24) of SMCRA 653 and to existing paragraph (a), with the exception that we propose to add a reminder that the permittee must comply with the fish and wildlife protection and enhancement plan approved in the permit. Proposed Paragraph (b): Species Listed or Proposed for Listing as Threatened or Endangered Existing 30 CFR 816.97(b) and (d) contain provisions that pertain to threatened and endangered species. We propose to consolidate those provisions in proposed paragraph (b). Proposed paragraph (b)(1) would set forth requirements concerning species that the U.S. Fish and Wildlife Service has listed or proposed for listing under the Endangered Species Act. Proposed paragraphs (b)(1)(i) through (iii) are substantively identical to the requirements of existing 30 CFR 816.97(b) with respect to federally-listed species, with four exceptions. First, we propose to replace the terms ‘‘consult’’ and ‘‘consultation’’ in the existing regulations with ‘‘contact and coordinate’’ and ‘‘in coordination with’’ to clarify that, in this context, these regulations do not refer to consultation under section 7(a)(2) of the Endangered Species Act. Second, we propose to expand the scope of paragraph (b)(1)(i) to include species proposed for listing as threatened or endangered under the Endangered Species Act, not just species actually listed under that law. We are proposing this change in response to discussions with the U.S. Fish and Wildlife Service. The proposed change is consistent with section 7(a)(4) of the Endangered Species Act, which provides that ‘‘[e]ach Federal agency shall confer with the Secretary on any agency action which is likely to jeopardize the continued existence of any species proposed to be listed under section 4 or result in the destruction or adverse modification of critical habitat proposed to be designated for such species.’’ It also would assist in implementing the fish and wildlife protection provisions of sections 515(b)(24) and 516(b)(11) of SMCRA. The conferencing requirement of section 7(a)(4) of the Endangered Species Act is not the same as the consultation 653 30 U.S.C. 1265(b)(24). VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 requirement for threatened and endangered species under section 7(a)(2) of the Endangered Species Act. Third, in proposed paragraph (b)(1)(ii), we propose to add a sentence clarifying that the requirement that the permittee report to the regulatory authority the presence of any federallylisted threatened or endangered species within the permit area applies regardless of whether the species was listed before or after permit issuance. We also propose to expand this notification requirement to apply to both the permit area and the adjacent area, not just the permit area as under the existing rule. We are proposing this change in response to discussions with the U.S. Fish and Wildlife Service concerning compliance with the Endangered Species Act. We are considering whether to limit the notification requirement of proposed paragraph (b)(1)(ii) to the active mining phase of the operation; i.e., whether the final rule should specify that the notification requirement expires at the time of Phase II bond release because of the typical lack of activity on the site after that stage of reclamation. We invite comment on this question. Fourth, in proposed paragraph (b)(1)(iii)(A), we propose to add a requirement that the regulatory authority issue a permit revision order under 30 CFR 774.10(b) when necessary to implement the results of the coordination process with state and federal fish and wildlife agencies following receipt of notification under proposed paragraphs (b)(1)(ii) and (iii). This requirement would apply only when revision of the operation and reclamation plan approved in the permit is necessary to ensure protection of federally-listed threatened and endangered species. Proposed paragraph (b)(1)(iv) would expressly require compliance with any species-specific protective measures required by the regulatory authority in coordination with the U.S. Fish and Wildlife Service. While proposed paragraph (b)(1)(iv) would be a new regulation, the requirement itself is a longstanding component of the result of a formal section 7(a)(2) consultation under the Endangered Species Act with respect to the continuation and approval of surface coal mining and reclamation operations under a SMCRA regulatory program. Proposed paragraph (b)(1)(v) is substantively identical to those elements of existing paragraph (d) that pertain to the Endangered Species Act; i.e., it would provide that nothing in our regulations authorizes the taking of a threatened or endangered species in PO 00000 Frm 00131 Fmt 4701 Sfmt 4702 44565 violation of the Endangered Species Act. Only the U.S. Fish and Wildlife Service may quantify allowable take of species listed as threatened or endangered. Proposed paragraph (b)(2) would set forth requirements pertaining to species listed as threatened or endangered under state statutes similar to the Endangered Species Act. It would include reporting and related requirements analogous to those of proposed paragraphs (b)(1)(ii) and (iii). Proposed Paragraph (c): Bald and Golden Eagles Existing paragraphs (c) and (d) both contain provisions that pertain to bald and golden eagles. We propose to consolidate those provisions in proposed paragraph (c). Proposed paragraphs (c)(1) through (3) are substantively identical to existing paragraph (c). Proposed paragraph (c)(4) would consist of those elements of existing paragraph (d) that pertain to the Bald and Golden Eagle Protection Act; i.e., it would provide that nothing in our regulations authorizes the taking of a bald or golden eagle, its nest, or its eggs in violation of the Bald and Golden Eagle Protection Act. Proposed Paragraph (d): Miscellaneous Protective Measures for Other Species of Fish and Wildlife We propose to redesignate existing paragraph (e), which contains miscellaneous provisions relating to protection of fish and wildlife in general, as paragraph (d). Proposed paragraph (d)(1) is substantively identical to existing paragraph (e)(1) with one exception. We propose to remove the clause allowing the regulatory authority to determine that is unnecessary to ensure that electric power transmission lines and other transmission facilities used for, or incidental to, surface mining activities on the permit area are designed and constructed to minimize electrocution hazards to raptors. We are not aware of any situations in which these precautions are not necessary or appropriate. We also propose to expand the scope of this paragraph to include all avian species with large wingspans, not just raptors, consistent with recommendations of the Avian Power Line Interaction Committee in a 2006 publication,654 which found that nonraptor avian species with large wingspans including, but not limited to, 654 Avian Power Line Interaction Committee (APLIC). 2006.

Proposed paragraph (d)(2) would require that the permittee locate, construct, operate, and maintain haul and access roads and sedimentation control structures in a manner that avoids or minimizes impacts on important fish and wildlife species or other species protected by state or federal law. It is substantively identical to existing paragraph (e)(2), except that we propose to add the words ‘‘construct’’ and ‘‘maintain’’ to be more consistent with the language of section 515(b)(17) of SMCRA,655 which requires that surface coal mining and reclamation operations be conducted so as to ‘‘insure that the construction, maintenance, and postmining conditions of access roads into and across the site of operations will control or prevent erosion and siltation, pollution of water, damage to fish or wildlife or their habitat, or public or private property.’’ We also propose to apply the requirements of proposed paragraph (d)(2) to sedimentation control structures to more effectively implement the fish and wildlife protection requirements of section 515(b)(24) of SMCRA.656 Proposed paragraphs (d)(3) and (4) are substantively identical to existing paragraphs (e)(3) and (4). Proposed paragraph (d)(5) would require that the permittee reclaim and reforest lands that were forested at the time of application and lands that would revert to forest under conditions of natural succession in a manner that enhances recovery of the native forest ecosystem as expeditiously as practicable. This provision would assist in implementation of the fish and wildlife protection provisions of section 515(b)(24) of SMCRA 657 and the revegetation requirements of section 515(b)(19) of SMCRA.658 Proposed Paragraph (e): Wetlands and Habitat of Unusually High Value for Fish and Wildlife We propose to redesignate existing paragraph (f), which pertains to wetlands, vegetation along rivers and streams and bordering ponds and lakes, and habitat of unusually high value for fish and wildlife, as paragraph (e) and revise it for clarity and to be consistent with section 515(b)(24) of SMCRA.659 The existing rule allows the permittee to select one of four options with respect 655 30 656 30 U.S.C. 1265(b)(17).

Hence, the existing rule is not fully consistent with section 515(b)(24) of SMCRA, which requires both minimization of disturbances and adverse impacts on fish, wildlife, and related environmental values to the extent possible and enhancement of those resources where practicable. Proposed paragraph (e) would improve consistency with section 515(b)(24) of SMCRA by requiring the permittee to enhance those resources where practical in all cases and by adding the qualifier ‘‘to the extent possible’’ with respect to the requirement to avoid disturbances to and restore or replace those resources. In accordance with accepted scientific terminology, we also propose to use the term ‘‘lentic’’ to refer to vegetation bordering lakes and ponds. As proposed, paragraph (e) would require the permittee to avoid disturbances to, restore or replace, and, where practicable, enhance, wetlands, riparian vegetation along rivers and streams, lentic vegetation bordering ponds and lakes, and habitat of unusually high value for fish and wildlife. Proposed Paragraph (f): Vegetation Requirements for Fish and Wildlife Habitat Postmining Land Use We propose to redesignate existing paragraph (g) as paragraph (f) and revise it by removing the requirement that plants used to revegetate areas with a fish and wildlife habitat postmining land use be arranged to maximize edge effect. Maximizing edge effect means that plantings would be designed to include the greatest amount of boundary areas between different types of natural habitats. It promotes the greatest species diversity, but also results in habitat fragmentation, which has deleterious effects on wildlife species that require large blocks of continuous habitat. We propose to replace that requirement with a provision that would require that the permittee select and arrange plant species to maximize the benefits to fish and wildlife. This change reflects current wildlife management philosophy, which emphasizes preservation or restoration of entire natural communities, rather than just those species that would benefit from the creation of edge effect. In addition, we propose to require the use of native species, prohibit the use of invasive plant species that are known to inhibit natural succession, and add a requirement that plant species be PO 00000 Frm 00132 Fmt 4701 Sfmt 4702 selected on the basis of their ability to sustain natural succession by allowing the establishment and spread of plant species across ecological gradients. These changes would improve implementation of section 515(b)(19) of SMCRA,660 which requires establishment of a ‘‘permanent vegetative cover of the same seasonal variety native to the area of land to be affected and capable of self-regeneration and plant succession.’’ Section 515(b)(19) 661 also provides that ‘‘introduced species may be used * * * where desirable and necessary to achieve the approved postmining land use plan.’’ We cannot envision any scenario in which introduced species would be either desirable or necessary to achieve a fish and wildlife habitat postmining land use. Proposed Paragraph (g): Vegetation Requirements for Cropland Postmining Land Use We propose to redesignate existing paragraph (h) as paragraph (g). Both paragraphs are substantively identical, but we propose to remove the phrase ‘‘throughout the harvested area’’ from the existing rule. That phrase is both unclear and unnecessary. Proposed Paragraph (h): Vegetation Requirements for Forestry Postmining Land Uses Proposed paragraph (h) would provide that any lands with either a managed or unmanaged forestry postmining land use must be replanted with native tree and understory species to the extent that doing so is not inconsistent with the type of forestry to be practiced as part of the postmining land use. This new paragraph also would require that plantings of commercial species be interspersed with plantings with native trees and shrubs of high value to wildlife, regardless of the type of forestry postmining land use. Proposed paragraph (h) would improve implementation of the revegetation requirements of section 515(b)(19) of SMCRA 662 and the provisions of section 515(b)(24) of SMCRA 663 concerning protection and enhancement of fish, wildlife, and related environmental values, as previously discussed. Proposed Paragraph (i): Vegetation Requirements for Other Postmining Land Uses We propose to revise existing paragraph (i) to add commercial and 660 30 U.S.C. 1265(b)(19). U.S.C. 1265(b)(24). 662 30 U.S.C. 1265(b)(19). 663 30 U.S.C. 1265(b)(24). 661 30 E:\FR\FM\27JYP2.SGM 27JYP2 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules tkelley on DSK3SPTVN1PROD with PROPOSALS2 intensive recreational uses to the list of postmining land uses for which the permittee must establish greenbelts to provide food and cover to wildlife. The uses that we propose to add are similar in intensity to the uses in the existing rule; therefore, the same requirements should apply. Proposed paragraph (i)(1) would require that the plants used to create the greenbelts be native and noninvasive, consistent with section 515(b)(19) of SMCRA 664 and the purpose of the greenbelts. In addition, proposed paragraph (i)(1) would create an exception to the greenbelt requirement when greenbelts would be inconsistent with the approved postmining land use for that site. Proposed paragraph (i)(2) would add another requirement for lands with the postmining land uses listed in the introductory text of proposed paragraph (i). Specifically, proposed paragraph (i)(2)(i) would require the establishment of a 100-foot buffer 665 comprised of native species, including species adapted to and suitable for planting in riparian zones, along each bank of all perennial and intermittent streams within the portion of the permit area for which these postmining land uses are approved. The species planted must consist of native tree and understory species if the land was forested at the time of application or if it would revert to forest under conditions of natural succession. The proposed requirements would improve implementation of the revegetation requirements of section 515(b)(19) of SMCRA 666 and the provisions of section 515(b)(24) of SMCRA 667 concerning protection and enhancement of fish, wildlife, and related environmental values, as previously discussed. Proposed paragraph (i)(2)(i) would provide an exception from the riparian buffer requirement when such a buffer would be incompatible with an approved postmining land use that is implemented during the revegetation responsibility period before final bond release under proposed § 800.42(d). Proposed Paragraph (j): Planting Arrangement Requirements Proposed paragraph (j) would require that plantings on all reclaimed areas be designed and arranged in a manner that will optimize benefits to wildlife to the extent practicable and consistent with the approved postmining land use.

Section 816.99: What measures must I take to prevent and remediate landslides? We propose to revise this section to improve adherence to plain language principles and to delete the reference to erosion in existing 30 CFR 816.99(a). The proposed deletion is appropriate because retention of an undisturbed natural barrier at the elevation of the lowest coal seam to be mined would not and could not play a role in preventing erosion on the disturbed area above the barrier. The role of such a barrier is limited to stability and preventing landslides. 29. Section 816.100: What are the standards for keeping reclamation contemporaneous with mining? We propose to revise this section to improve adherence to plain language principles and to add stream restoration to the list of reclamation activities that are subject to the contemporaneous reclamation requirement. Existing 30 CFR 816.100 states that reclamation activities include, but are not limited to, those specifically listed in the rule. Therefore, we consider our proposed addition of stream restoration to the list of activities to be a clarification of the existing regulation. 30. Why are we proposing to remove existing 30 CFR 816.101? As adopted on December 17, 1991, 30 CFR 816.101 established time and distance requirements for rough backfilling and grading following coal removal. However, we subsequently suspended this section, effective August 31, 1992, as a result of a Joint Stipulation of Dismissal in litigation following the issuance of that rule. See 57 FR 33874, 33875 (Jul. 31, 1992) and Nat’l Coal Ass’n et al. v. U.S. Dep’t of the Interior, et al., Civ. No. 92–0408– CRR (D.D.C.). We now propose to lift the suspension and remove this section as part of our rewrite of the backfilling and grading requirements. Removal of a section that has not been in effect for almost 20 years would improve the clarity of our requirements and avoid the confusion that can result on the part of persons who are not aware of the suspension. The contemporaneous reclamation requirements of 30 CFR 816.100, in combination with the site-specific 668 Id. PO 00000 Frm 00133 reclamation timetable approved in the permit, should be sufficient to ensure that permittees complete rough backfilling and grading in a timely manner. The reclamation timetable requirement currently appears in existing 30 CFR 780.18(b)(3), which we propose to redesignate as 30 CFR 780.12(b). Proposed 30 CFR 780.12(b) also would require that the reclamation timetable include application for each phase of bond release under proposed 30 CFR 800.42 because reclamation cannot be considered complete until the regulatory authority releases all bond posted for the site in accordance with proposed 30 CFR 800.42(d). 31. Section 816.102: How must I backfill the mined area and configure the land surface? We propose to revise and restructure this section to clarify exactly when and where our approximate original contour restoration requirements apply, consistent with our proposed revisions to the definition of approximate original contour in 30 CFR 701.5 and other statutory and regulatory requirements. Section 515(b)(3) of SMCRA 669 provides the primary statutory basis for both the existing rules and the changes that we are proposing. In relevant part, section 515(b)(3) requires that surface coal mining and reclamation operations ‘‘compact (where advisable to insure stability or to prevent leaching of toxic materials), and grade in order to restore the approximate original contour of the land with all highwalls, spoil piles, and depressions eliminated (unless small depressions are needed in order to retain moisture to assist revegetation or as otherwise authorized pursuant to this Act).’’ It also provides exceptions to this requirement for mountaintop removal mining operations and thin and thick overburden situations. Proposed Paragraph (a) We propose to revise the introductory language of paragraph (a) to clarify that the backfilling requirement applies only to mined areas, while the grading requirement applies to the entire disturbed area. The existing rule applies the backfilling requirement to the entire disturbed area. However, those portions of the disturbed area outside the mined area do not contain a pit or similar excavation that requires backfilling. (See the preamble discussion of our proposed definition of backfill in 30 CFR 701.5.) Those areas only require grading to restore the approximate original contour in compliance with 669 30 Fmt 4701 Sfmt 4702 44567 E:\FR\FM\27JYP2.SGM U.S.C. 1265(b)(3). 27JYP2 tkelley on DSK3SPTVN1PROD with PROPOSALS2 44568 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules section 515(b)(3) of SMCRA.670 We also propose to require that the backfilling and grading of the minesite adhere to the plan approved in the permit in accordance with 30 CFR 780.12(d). Proposed paragraphs (a)(1)(i) through (ix) list exceptions from the requirement to restore the approximate original contour as the final surface configuration of the backfilled and regraded area. The exceptions in proposed paragraphs (a)(1)(i) through (v) correspond to the exceptions that appear in existing paragraph (k) and are substantively identical to those exceptions. We propose to reword the exception in proposed paragraph (a)(1)(v) to emphasize that the exception for remining operations applies only to the extent specified in 30 CFR 816.106(b); i.e., it is limited to an exception from the highwall elimination requirement. This proposed revision would not change existing law, policy, or practice, but it would add clarity concerning the scope of the exception. Proposed paragraphs (a)(1)(vi) and (vii) would clarify that excess spoil fills constructed in accordance with 30 CFR 816.71 or 816.74 and refuse piles constructed in accordance with 30 CFR 816.83 do not need to comply with approximate original contour restoration requirements. The rationale for these two exceptions appears in the preamble discussion of our proposed revisions to the definition of approximate original contour in 30 CFR 701.5. Proposed paragraph (a)(1)(viii) would clarify that permanent impoundments that meet the requirements of proposed paragraph (a)(3)(ii) and proposed § 780.35(b)(4) are exempt from compliance with approximate original contour restoration requirements. The proposed exception is consistent with the definition of approximate original contour in section 701(2) of SMCRA,671 which contains a clause specifying that ‘‘water impoundments may be permitted’’ if they comply with the permanent impoundment provisions of section 515(b)(8) of SMCRA.672 The regulations implementing section 515(b)(8) of SMCRA are located at 30 CFR 816.49(b). Proposed 30 CFR 816.102(a)(3)(ii) would require compliance with 30 CFR 816.49(b). Approval of a permanent impoundment would not exempt the permittee from complying with all applicable approximate original contour restoration requirements on the remainder of the disturbed area. Proposed paragraph (a)(1)(ix) would allow the placement of overburden that otherwise would be classified as excess spoil on the mined-out area to heights in excess of the premining elevation when necessary to avoid or minimize construction of excess spoil fills on undisturbed land, provided that the placement occurs in accordance with proposed 30 CFR 780.35(b)(3). This provision would harmonize the approximate original contour restoration requirement of section 515(b)(3) of SMCRA 673 with section 515(b)(24) of SMCRA,674 which requires that surface coal mining and reclamation operations use the best technology currently available to ‘‘minimize disturbances and adverse impacts of the operation on fish, wildlife, and related environmental values’’ to the extent possible. Streams are generally recognized as among the habitats with the highest value to fish, wildlife, and related environmental values. To minimize both the amount of land disturbed and the length of stream segments buried or otherwise adversely affected, proposed 30 CFR 780.35(b)(3) provides that premining elevations would not operate as a cap on the elevation of backfilled areas. Instead, the final elevation would be determined on the basis of the factors listed in proposed 30 CFR 780.35(b)(2)(ii) through (v), together with the requirement in 30 CFR 780.35(b)(3) that the final surface configuration be compatible with the natural drainage pattern and the surrounding terrain. Proposed paragraph (a)(2) is substantively identical to existing paragraph (g), with the exception of a proposed requirement that backfilling and grading be conducted in a manner that minimizes the creation of uniform slopes and cut-and-fill terraces. Both uniform slopes and cut-and-fill terraces are rarely found in nature and thus normally would not be considered consistent with the concept of approximate original contour restoration. However, the definition of approximate original contour in section 701(2) of SMCRA 675 contains language allowing terracing. Therefore, the proposed rule would continue to allow the construction of cut-and-fill terraces under certain conditions for specified purposes, as in the existing rules. Proposed paragraph (a)(3), like existing paragraph (a)(2), would require the elimination of all highwalls, spoil piles, and depressions, with certain exceptions. We propose to add impoundments to this list for clarity, although this addition would not be a substantive change. Proposed paragraph (a)(3)(i)(A), like existing paragraph (h), would allow the construction of small depressions if they are needed to retain moisture, minimize erosion, create or enhance wildlife habitat, or assist revegetation. Proposed paragraph (a)(3)(i) would add two other requirements that must be met before small depressions may be created or retained. First, proposed paragraph (a)(3)(i)(B) would require that the depressions be consistent with the hydrologic reclamation plan approved in the permit in accordance with proposed 30 CFR 780.22. Second, proposed paragraph (a)(3)(i)(C) would require that the permittee demonstrate that the depressions would not result in elevated levels of parameters of concern (e.g., total dissolved solids and selenium) in discharges from the backfilled and graded area. The two new requirements are intended to ensure protection of the hydrologic balance in accordance with section 515(b)(10) of SMCRA,676 which provides that surface coal mining and reclamation operations must be conducted to ‘‘minimize the disturbances to the prevailing hydrologic balance at the mine-site and in associated offsite areas and to the quality and quantity of water in surface and ground water systems both during and after surface coal mining operations and during reclamation.’’ Proposed paragraphs (a)(3)(i)(B) and (C) also would improve implementation of section 515(b)(3) of SMCRA,677 which requires, in pertinent part, that surface coal mining and reclamation operations shape and grade overburden or spoil ‘‘in such a way as to prevent * * * water pollution.’’ Proposed paragraph (a)(3)(ii), like existing paragraph (i), would allow the retention of permanent impoundments if they are suitable for the approved postmining land use and if they meet the requirements of 30 CFR 816.49 and 816.56. We propose to add a provision allowing the retention of permanent impoundments only if the permittee has demonstrated compliance with the future maintenance requirements of proposed 30 CFR 800.42(c)(5). The new provision would improve implementation of section 519(c)(2) of SMCRA,678 which provides that ‘‘[w]here a silt dam is to be retained as a permanent impoundment pursuant to section 515(b)(8) 679 [the statutory counterpart to 30 CFR 816.49(b)],’’ 676 30 670 Id. 671 30 672 30 673 30 U.S.C. 1265(b)(3). 674 30 U.S.C. 1265(b)(24). 675 30 U.S.C. 1291(2).

This provision would apply only when the impoundment is located in waters of the United States. It is intended to encourage coordination and cooperation with the Clean Water Act permitting authority. Proposed paragraph (a)(3)(iii), like existing paragraph (a)(2), would allow the permittee to retain highwalls on previously mined areas to the extent provided in § 816.106(b). Proposed paragraph (a)(3)(iv) would allow retention of modified highwall segments to the extent necessary to replace similar natural landforms; i.e., cliffs or bluffs, removed by the mining operation. The proposed rule would harmonize two provisions of section 515(b)(3) of SMCRA 680 that may pose a potential conflict in certain situations: the requirement to restore the approximate original contour and the requirement to eliminate all highwalls. The proposed rule would allow the retention of highwall segments to replace cliffs or bluffs destroyed by mining, but only if the highwall segments are modified to closely resemble the features destroyed by mining and to restore the ecological functions of those features. For example, ledges may need to be blasted into the highwall face to provide nesting habitat for raptors and other cliff-dwelling wildlife and microhabitats may need to be created at the base of the highwall remnant. The proposed rule would specify that the number, length, and height of any modified highwall segments retained may not exceed the number, length, and height of the premining features that they replace. In addition to harmonizing potentiallyconflicting requirements within section 515(b)(3) of SMCRA,681 the proposed rule would require restoration of valuable wildlife habitat, which would improve implementation of section 515(b)(24) of SMCRA.682 Section 515(b)(24) requires that, to the extent possible, surface coal mining and reclamation operations use the best technology currently available to U.S.C. 1265(b)(3). U.S.C. 1265(b)(3). 682 30 U.S.C. 1265(b)(24). minimize disturbances and adverse impacts on fish, wildlife, and related environmental values and to achieve enhancement of those resources where practicable. Under the proposed rule, the regulatory authority would have to amend its regulatory program to establish the conditions under which highwall segments may be retained and the modifications that must be made to those highwall segments to ensure that the retained segment restores the form and ecological function of similar premining landforms. We have already approved highwall retention provisions of this nature as part of the New Mexico and Utah regulatory programs.683 The New Mexico program provision, CSMC Rule 20–102(a)(2), allows the retention of limited stretches of highwall if similar features were part of the natural landscape of the mine area prior to mine operations. In addition, the following requirements apply: • The highwall must have a static safety factor of 1.3. • The highwall must not pose a hazard to persons or wildlife in the area. • The highwall must be backfilled to cover the uppermost coal seam to a minimum depth of 4 feet. • The retained portion of the highwall may not exceed 800 feet in length and must be a minimum of at least 3,000 feet from any other portion of any other highwall remnant approved for retention as part of the postmining land use. • The highwall is necessary to replace cliff-type habitats that existed in the natural topography prior to mining. • The ends of the highwall left standing must be contoured into the surrounding topography with slopes of 3:1 or less. The Utah program provision (Utah Administrative Code R645–301– 553.650) allows a permittee to seek approval to retain highwalls when the proposed highwall remnant would meet all stability requirements and the following criteria: • The remaining highwall will not be greater in height or length than the cliffs and cliff-like escarpments that were replaced or disturbed by the mining operations. • The remaining highwall will replace a preexisting cliff or similar natural premining feature and will resemble the structure, composition, and function of the natural cliff it replaces. • The remaining highwall will be modified, if necessary, as determined by 680 30 VerDate Sep<11>2014 19:15 Jul 24, 2015 the regulatory authority, to restore clifftype habitats used by the flora and fauna existing prior to mining. • The remaining highwall will be compatible with the postmining land use and the visual attributes of the area. • The remaining highwall will be compatible with the geomorphic processes of the area. We invite comment on whether we should include any of these specific state program criteria in our rule for national applicability. Proposed paragraph (a)(4) is substantively identical to existing paragraph (a)(3). Proposed paragraph (a)(5), like existing paragraph (a)(4), would require that backfilling and grading be conducted to minimize erosion and water pollution both on and off the site. We propose to add language clarifying that the requirement to minimize water pollution includes discharges of parameters of concern for which no numerical effluent limitations or water quality standards have been established. Our proposed revision is in accordance with section 515(b)(10) of SMCRA,684 which provides that surface coal mining and reclamation operations must be conducted to ‘‘minimize the disturbances to the prevailing hydrologic balance at the mine-site and in associated offsite areas and to the quality and quantity of water in surface and ground water systems both during and after surface coal mining operations and during reclamation.’’ Proposed paragraph (a)(6) is identical to existing paragraph (a)(5). Proposed Paragraph (b) Existing paragraph (b) requires that all spoil except excess spoil disposed of in accordance with 30 CFR 816.71 or 816.74 be returned to the mined-out area. We propose to revise this paragraph by adding an exception in proposed paragraph (b)(2) for mountaintop removal mining operations. Under section 515(c)(4)(E) of SMCRA,685 spoil from mountaintop removal mining operations need not be returned to the mined-out area, provided any spoil not returned to the mined-out area is placed in accordance with the excess spoil disposal requirements of section 515(b)(22) of SMCRA.686 Mountaintop removal mining operations are designed to create a level plateau or gently rolling contour where mountainous topography existed before mining, which limits the amount 684 30 681 30 683 45 FR 86459 (Dec. 31, 1980) and 58 FR 48600 (Sept. 17, 1993), respectively.

Proposed paragraph (b)(3) would include the exception in existing paragraph (d) for spoil used to blend the mined-out area into the surrounding terrain, with revisions to reflect our proposed changes to 30 CFR 816.22 concerning the salvage, storage, redistribution, and use of soil materials and organic matter. We also propose to remove existing paragraph (d)(3), which requires that spoil used for blending be backfilled and graded in accordance with the requirements of 30 CFR 816.102. Existing paragraph (d)(3) is redundant because the requirements of 30 CFR 816.102 automatically apply to all backfilling and grading activities unless specifically exempted. tkelley on DSK3SPTVN1PROD with PROPOSALS2 Proposed Paragraph (c) Existing paragraph (c) requires the compaction of spoil and waste materials where advisable to ensure stability or to prevent the leaching of toxic materials. For clarity and consistency with the terminology used elsewhere in our regulations, we propose to replace the phrase ‘‘the leaching of toxic materials’’ with ‘‘the formation of acid or toxic mine drainage.’’ We also propose to add a requirement to avoid compacting materials placed in what will be the root zone of the species planted under the revegetation plan approved in the permit in accordance with proposed 30 CFR 780.12(g) to the extent possible. As discussed in the portion of this preamble concerning proposed 30 CFR 780.12(e) and 816.22, soil compaction is a major inhibitor of plant growth and productivity, especially for trees and shrubs. Therefore, compaction of the root zone must be minimized to achieve the revegetation requirements of section 515(b)(19) of SMCRA 687 and the postmining land use capability requirements of section 515(b)(2) of SMCRA.688 Proposed Paragraph (d) Proposed paragraph (d) would include existing paragraph (f), which requires the covering or treatment of all exposed coal seams and acid-forming materials, toxic-forming materials, and combustible materials. We propose to revise the existing rule by establishing separate requirements for exposed coal seams, acid-forming and toxic-forming materials, and combustible materials to reflect the different nature of these materials and to clarify which requirements apply to which materials. Proposed paragraph (d)(1) would require that all exposed coal seams be covered with material that is noncombustible, nonacid-forming, and nontoxic-forming to prevent coal seam fires and the development of acid or toxic mine drainage. Proposed paragraph (d)(2) would require that all other combustible materials exposed, used, or produced during mining be handled and disposed of in accordance with 30 CFR 816.89 (noncoal waste materials) in a manner that will prevent sustained combustion. Proposed paragraph (d)(3) would require that the permittee handle and place all other acid-forming or toxic-forming materials in compliance with the plan approved in the permit in accordance with proposed 30 CFR 780.12(d)(4); in compliance with 30 CFR 816.38, which governs the handling and placement of acid-forming and toxic-forming materials; in compliance with the hydrologic reclamation plan approved in the permit in accordance with proposed 30 CFR 780.22(a); and in a manner that will minimize adverse effects on plant growth and the approved postmining land use. The proposed revisions described above would improve implementation of section 515(b)(10) of SMCRA,689 which provides that surface coal mining and reclamation operations must be conducted to ‘‘minimize the disturbances to the prevailing hydrologic balance at the mine-site and in associated offsite areas and to the quality and quantity of water in surface and ground water systems both during and after surface coal mining operations and during reclamation.’’ They also would more fully implement those provisions of section 515(b)(3) of SMCRA 690 that discuss the handling of acid-forming and toxic materials during backfilling and grading, as well as section 515(b)(14) of SMCRA,691 which contains requirements for the handling and disposal of acid-forming and toxic materials and materials constituting a fire hazard. Proposed Paragraph (e) We propose to revise this paragraph by updating the terminology to reflect our 1983 rulemaking in which we introduced the term ‘‘coal mine waste’’ to include both coal processing waste and underground development waste.692 689 30 U.S.C. 1265(b)(10).

Proposed Paragraph (f) Proposed paragraph (f) is substantively identical to existing paragraph (j) except that we propose to revise this paragraph by replacing the references to ‘‘topsoil’’ with the term ‘‘soil materials’’ to be consistent with our proposed changes to 30 CFR 816.22. 32. Section 816.104: What special provisions for backfilling, grading, and surface configuration apply to sites with thin overburden? We propose to revise this section, which implements the thin overburden exception in section 515(b)(3) of SMCRA,693 for clarity. Our proposed revisions to existing paragraph (a) would resolve ambiguities and convert the definition to a description of the situations in which the thin overburden provisions of 30 CFR 816.104 would apply. In proposed paragraph (a)(1), we propose to replace the term ‘‘land’’ with ‘‘mined area’’ to emphasize that the determination as to whether the postmining surface configuration closely resembles the premining surface configuration must be made with respect to the mined area, not the surrounding area. We also propose to insert ‘‘any’’ before ‘‘mining’’ to clarify that, when the permit area has been previously mined, the premining surface configuration must be the surface configuration that existed before any mining, not the surface configuration of the existing previously mined area. The preamble to our proposed revisions to the definition of approximate original contour in 30 CFR 701.5 contains further discussion of these matters. In proposed paragraph (b), we propose to retain the existing performance standards for thin overburden at 30 CFR 816.104(b)(1) and (2), with appropriate plain language and citation changes. Among other things, the existing standards require that the permittee use all spoil and waste materials available from the entire permit area to attain the lowest practicable grade that does not exceed the angle of repose.

This requirement is intended to harmonize the reclaimed area with surrounding areas. 33. Section 816.105: What special provisions for backfilling, grading, and surface configuration apply to sites with thick overburden? We propose to revise this section, which implements the thick overburden exception in section 515(b)(3) of SMCRA,695 for clarity. Our proposed revisions to existing paragraph (a) would resolve ambiguities and convert the definition to a description of the situations in which the thick overburden provisions of 30 CFR 816.105 would apply. In proposed paragraph (a)(1), we propose to replace the term ‘‘land’’ with ‘‘mined area’’ to emphasize that the determination as to whether the postmining surface configuration closely resembles the premining surface configuration must be made with respect to the mined area, not the surrounding area. We also propose to insert ‘‘any’’ before ‘‘mining’’ to clarify that, when the permit area has been previously mined, the premining surface configuration must be the surface configuration that existed before any mining, not the surface configuration of the existing previously mined area. The preamble to our proposed revisions to the definition of approximate original contour in 30 CFR 701.5 contains further discussion of these matters. We also propose to delete the provision in our existing rules that a thick overburden situation exists when the amount of material to be returned to the mined-out area is so large that it is not possible to achieve a surface configuration that blends into and complements the drainage pattern of the surrounding terrain. We are aware of no circumstances in which this situation would exist. We propose to revise the performance standards for thick overburden operations in existing paragraph (b) by adding an introductory reminder that all backfilling and grading activities must comply with the backfilling and grading plan approved in the permit under proposed 30 CFR 780.12(d). We also propose to revise existing paragraph (b) to improve consistency with the underlying statutory provisions and to reflect other rule changes that we are proposing. In relevant part, section 515(b)(3) of SMCRA 696 provides— That in surface coal mining where the volume of overburden is large relative to the thickness of the coal deposit and where the operator demonstrates that due to volumetric expansion the amount of overburden and other spoil and waste materials removed in the course of the mining operation is more than sufficient to restore the approximate original contour, the operator shall after restoring the approximate original contour, backfill, grade, and compact (where advisable) the excess overburden and other spoil and waste materials to attain the lowest grade but not more than the angle of repose, and to cover all acid-forming and other toxic materials, in order to achieve an ecologically sound land use compatible with the surrounding region and that such overburden or spoil shall be shaped and graded in such a way as to prevent slides, erosion, and water pollution and is revegetated in accordance with the requirements of the Act[.] To implement this provision, proposed 30 CFR 816.105(b)(1) would require that the permittee backfill the mined-out area to the approximate original contour and then place the remaining spoil and waste materials on top of the backfilled area to the extent possible, as determined in accordance with the excess spoil minimization requirements of proposed 30 CFR 780.35(b). Section 515(b)(3) of SMCRA could be interpreted as requiring return of all spoil and waste materials to the mined-out area, but such a reading would not be the best interpretation of the statute. Nor is it technically possible to return all spoil from many steepslope mining operations to the minedout area. Section 515(b)(22) of SMCRA 697 recognizes that mining operations may generate excess spoil. Accordingly, it establishes requirements governing placement of excess spoil outside the mined-out area.

Proposed 30 CFR 816.105(b)(2) would require that the spoil and waste materials placed on top of the backfilled area be graded to the lowest practicable grade that is ecologically sound, consistent with the postmining land use, and compatible with the surrounding region. No slope may exceed the angle of repose. Proposed paragraph (b)(2) would be consistent with the language in section 515(b)(3) of SMCRA,698 which requires that the operator ‘‘backfill, grade, and compact (where advisable) the excess overburden and other spoil and waste materials to attain the lowest grade but not more than the angle of repose * * * in order to achieve an ecologically sound land use compatible with the surrounding region.’’ Proposed 30 CFR 816.105(b)(3), like existing 30 CFR 816.105(b)(2), would continue to require compliance with most of the backfilling, spoil and soil placement, grading, and surface configuration requirements of 30 CFR 816.102, with the notable exception of the requirement in 30 CFR 816.102(a)(1) for restoration of the approximate original contour as the final surface configuration. Among other things, proposed paragraph (b)(3) would implement or facilitate implementation of those provisions of section 515(b)(3) of SMCRA that require (1) covering of all acid-forming and other toxic materials, (2) compaction of spoil and waste materials where advisable, (3) shaping and grading of overburden and spoil ‘‘in such a way as to prevent slides, erosion, and water pollution,’’ and (4) revegetation. Proposed 30 CFR 816.105(b)(4), like existing 30 CFR 816.105(b)(3), would continue to require that any excess spoil be placed in accordance with the excess spoil disposal requirements of 30 CFR 816.71 or 816.74. As provided in our proposed definition of excess spoil in 30 CFR 701.5, this requirement would apply to all spoil material placed above the approximate original contour within the mined-out area as part of the continued construction of an excess spoil fill with a toe located outside the mined-out area. 698 30 E:\FR\FM\27JYP2.SGM U.S.C. 1265(b)(3). 27JYP2 44572 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules Proposed paragraph (b)(5) would require that the final surface configuration blend into and complement the drainage pattern of the surrounding terrain to the extent possible.

Section 816.107: What special provisions for backfilling, grading, and surface configuration apply to steep slopes? We propose to revise existing paragraph (d) of this section, which governs the disposal of woody materials on steep-slope mining sites, for consistency with proposed 30 CFR 816.22(f). The existing rule provides that woody materials may not be buried in the backfill unless the regulatory authority determines that doing so would not create stability problems. However, as discussed in the preamble to proposed 30 CFR 816.22(f), woody materials are sufficiently valuable for revegetation and fish and wildlife enhancement purposes that they should be used for those purposes rather than being buried or burned. Therefore, we propose to revise 30 CFR 816.107(d) to prohibit the burial of woody materials in the backfill and to require that the permittee instead handle those materials in accordance with proposed 30 CFR 816.22(f). 36. Section 816.111: How must I revegetate the area disturbed by mining? We propose to revise and restructure this section for clarity and consistency with other proposed rule changes. We also propose to move existing paragraphs (b) and (c) and most of existing paragraph (d) to proposed 30 CFR 780.12(g) because they are permitting requirements that pertain to development of the revegetation plan. We propose to delete the sentence in VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 existing paragraph (d) stating that the requirements of 30 CFR part 823 apply to prime farmland. This sentence is unnecessary because by its own terms 30 CFR part 823 applies to all prime farmland. In addition, we propose to redesignate existing 30 CFR 816.113 and 816.114 as proposed paragraphs (e) and (d), respectively, of 30 CFR 816.111. Most of our proposed substantive revisions are intended to improve the implementation of section 515(b)(2) of SMCRA,699 which requires that surface coal mining and reclamation operations ‘‘restore the land affected to a condition capable of supporting the uses which it was capable of supporting prior to any mining, or higher or better uses of which there is reasonable likelihood,’’ and section 515(b)(19) of SMCRA,700 which provides that surface coal mining and reclamation operations must— establish on the regraded areas, and on all other lands affected, a diverse, effective, and permanent vegetation cover of the same seasonal variety native to the area of land to be affected and capable of self-regeneration and plant succession at least equal in extent of cover to the natural vegetation of the area; except, that introduced species may be used in the revegetation process where desirable and necessary to achieve the approved postmining land use plan[.] The proposed revisions are necessary in part because an approved higher or better postmining land use is not always implemented during the revegetation responsibility period. Requiring initial revegetation with native species would promote environmentally-sound reclamation and enhance fish and wildlife habitat without precluding implementation of the higher or better use at a later date. The increased emphasis on revegetation with native species also would prevent proliferation of instances in which backfilled and graded minesites have not been revegetated with a permanent vegetative cover of the same seasonal variety native to the area, as required by section 515(b)(19) of SMCRA. Proposed Paragraph (a) We propose to revise existing paragraph (a) to clarify that the revegetation requirements of 30 CFR 816.111 do not apply to rock piles and other rock or non-vegetative features created to restore or enhance wildlife habitat under the fish and wildlife protection and enhancement plan approved in the permit in accordance with 30 CFR 780.16.

Finally, we propose to clarify that the revegetation exemption for water areas applies only to water areas approved as part of or in support of the postmining land use or approved as part of the fish and wildlife protection and enhancement plan in the permit. Proposed Paragraph (b) Proposed paragraph (b) would require that the reestablished vegetative cover comply with the revegetation plan approved in the permit in accordance with proposed 30 CFR 780.12(g). It also would require that the vegetative cover be consistent with both the approved postmining land use and establishment of the plant communities described in the permit application as required by proposed 30 CFR 779.19. In addition, proposed paragraph (b) would require that the vegetative cover be capable of stabilizing the soil surface and, in the long term, preventing erosion in excess of what would have occurred naturally had the site not been disturbed. Background erosion levels on undisturbed sites vary from region to region and site to site, depending on geology, soils, topography, and climate. Further, proposed paragraph (b) would require that the vegetative cover not inhibit the establishment of woody plants when the revegetation plan requires the use of woody plants. Extensive herbaceous ground cover can inhibit the establishment and growth of trees and shrubs, which would provide more effective long-term surface stabilization and erosion control in areas that are naturally forested. The dense herbaceous ground covers often used in the past to control erosion on regraded sites compete with newlyplanted trees and tree seedlings for soil nutrients, water, and sunlight and provide habitat and cover for rodents and other animals that damage tree seedlings and young trees. An article in a technical publication provides the following summary of the effects of ground cover on establishment of trees on mined lands: The negative effects of overly abundant and aggressive ground cover on the survival and growth of trees planted on reclaimed mine lands has long been known. Trees planted into introduced, aggressive forages [especially tall fescue and sericea lespedeza] often are overtopped by the grass or legume and are unable to break free (Burger and Torbert, 1992; Torbert et al., 1995). The seedlings are pinned to the ground and have E:\FR\FM\27JYP2.SGM 27JYP2 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules little chance for survival. If it is known that trees are to be planted, a tree-compatible ground cover should be seeded that will be less competitive with trees. Tree-compatible ground cover should be slow growing, sprawling or low growing, not allopathic, and non-competitive with trees (Burger and Torbert, 1992). Plass (1968) reported that after four growing seasons the height growth of sweetgum and sycamore planted into an established stand of tall fescue on spoil banks was significantly retarded. Andersen et al. (1989) found that survival and height growth for red oak and black walnut was significantly greater on sites where ground cover was chemically controlled.701 desirable components of the plant communities described in the permit application under proposed 30 CFR 779.19 and that are not inconsistent with the postmining land use to be considered in determining whether the revegetation requirements of 30 CFR 816.111 and 816.116 have been met. Proposed paragraph (c) would be consistent with existing practice and with the requirement to establish a vegetative cover capable of selfregeneration and plant succession in section 515(b)(19) of SMCRA.704 Researchers from the University of Maine determined that even a small amount (less than 20 percent) of herbaceous ground cover around tree seedlings will substantially reduce early stand growth.702 Another study of revegetation of mined lands in Appalachia found that dense ground covers prevent the natural seeding-in of native plants, while low ground cover seeding rates allowed the invasion of light-seeded native trees such as yellow poplar, red maple, and birches.703 The amount of vegetative ground cover necessary to control erosion on any particular site is a function of the site topography, composition of the surface material, precipitation frequency and intensity, and the degree of soil compaction. Loosely graded or uncompacted material, particularly if placed on a relatively gentle slope, may have virtually no runoff or erosion and would require little or no herbaceous vegetative ground cover to control erosion. Conversely, highly-compacted material placed on a steep slope severely limits infiltration and increases runoff so that a dense vegetative cover may be needed to control erosion. We invite comment on whether proposed paragraphs (b)(4) and (5) strike the proper balance between the need for erosion control and the conditions required to promote establishment of native trees and shrubs, or whether adjustments are needed. Proposed Paragraph (d) Proposed paragraph (d), which would include existing 30 CFR 816.114, would require that all areas upon which soil materials have been redistributed be stabilized either by establishing a temporary vegetative cover consisting of noncompetitive and non-invasive species or by applying a hay mulch (native hay would be required when commercially available) that is free of weed and noxious plant seeds. These methods could be used alone or in combination. In addition, proposed paragraph (d) would allow the regulatory authority to waive this requirement if it determines that neither method is necessary to stabilize the surface and control erosion. Proposed paragraph (d) is intended to promote establishment of ‘‘a diverse, effective, and permanent vegetative cover of the same seasonal variety native to the area of land to be affected and capable of self-regeneration and plant succession,’’ as required by section 515(b)(19) of SMCRA.705 The preamble to proposed paragraph (b) explains the obstacle that dense herbaceous ground covers comprised of aggressive perennial species like tall fescue and sericea lespedeza present to the establishment of trees and shrubs and, hence, to achieving the type of postmining plant community that SMCRA requires. tkelley on DSK3SPTVN1PROD with PROPOSALS2 Proposed Paragraph (c) Proposed paragraph (c) would allow volunteer plants of species that are 701 King, J. and J.

Section 816.115: How long am I responsible for revegetation after planting? Proposed 30 CFR 816.115 is substantively identical to the provisions concerning revegetation responsibility periods in existing 30 CFR 816.116(c), with one exception. Proposed paragraph (a)(2) would provide that the initial planting of small areas that are regraded and planted as a result of the removal of sediment control structures and associated structures and facilities (e.g., diversion ditches, disposal and storage areas for accumulated sediment, sediment pond embankments, and ancillary roads used to access those structures) need not be considered an augmented seeding necessitating an extended or separate revegetation responsibility period. This proposed paragraph is not a new proposal; its adoption would merely incorporate into regulation the policy upon which we previously provided notice and opportunity for comment 706 and subsequently adopted in the context of the approval of several state regulatory program amendments.707 The following discussion from the preamble to our approval of the Illinois program amendment sets forth the rationale for our policy: Section 515(b)(20) of SMCRA provides that the revegetation responsibility period shall commence ‘‘after the last year of augmented seeding, fertilizing, irrigation, or other work’’ needed to assure revegetation success. In the absence of any indication of Congressional intent in the legislative history, OSM interprets this requirement as applying to the increment or permit area as a whole, not individually to those lands within the permit area upon which revegetation is delayed solely because of their use in support of the reclamation effort on the planted area. As implied in the preamble discussion of 30 CFR 816.46(b)(5), which prohibits the removal of ponds or other siltation structures until two years after the last augmented seeding, planting of the sites from which such structures are removed need not itself be considered an augmented seeding necessitating an extended or separate liability period (48 FR 44038–44039, September 26, 1983). The purpose of the revegetation responsibility period is to ensure that the mined area has been reclaimed to a condition capable of supporting the desired permanent vegetation. Achievement of this purpose will not be adversely affected by this 706 See 58 FR 48333 (Sept. 15, 1993). e.g., Colorado (61 FR 26792, 26796–26797 (May 29, 1996)), Illinois (62 FR 55765–55769 Oct. 22, 1997)), and Ohio (63 FR 51829–51833 (Sept. 29, 1998)). 707 See, E:\FR\FM\27JYP2.SGM 27JYP2 44574 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules with proposed 30 CFR 779.22(b). This approach is also consistent with the legislative history of section 508 of SMCRA,710 in which Congress states: ‘‘It is important that the potential utility which the land had for a variety of uses be the benchmark rather than any single, possibly low value, use which by circumstances may have existed at the time mining began.’’ 711 We propose to require that minesites be revegetated in a manner that will restore the native plant communities described in the permit application in accordance with proposed 30 CFR 779.19, regardless of the approved postmining land use. The proposed rule contains an exception for those portions of the permit area on which the approved postmining land use is implemented before the end of the revegetation responsibility period under proposed 30 CFR 816.115, but that exception would apply only if restoration of native plant communities would be inconsistent with that use, as may be the case with agricultural, commercial, industrial, and residential postmining land uses. This approach would improve implementation of section 515(b)(19) of SMCRA,712 which provides that surface coal mining and reclamation operations must— Neither the policy nor the state program amendment approvals extend to the removal of haul roads or other primary roads. Because of the difficulty in reestablishing vegetation on the surfaces of primary roads, that type of road may need to be bonded separately for purposes of the revegetation liability period, unless the road is approved for retention as part of the postmining land use. tkelley on DSK3SPTVN1PROD with PROPOSALS2 interpretation of section 515(b)(20) of SMCRA since (1) the lands involved are relatively small in size and either widely dispersed or narrowly linear in distribution and (2) the delay in establishing revegetation on these sites is due not to reclamation deficiencies or the facilitation of mining, but rather to the regulatory requirement that ponds and diversions be retained and maintained to control runoff from the planted area until the revegetation is sufficiently established to render such structure unnecessary for the protection of water quality. In addition, the areas affected likely would be no larger than those which could be reseeded (without restarting the revegetation period) in the course of performing normal husbandry practices, as that term is defined in 30 CFR 816.116(c)(4) and explained in the preamble to that rule (53 FR 34636, 34641; September 7, 1988; 52 FR 28012, 28016; July 27, 1987). Areas this small would have a negligible impact on any evaluation of the permit area as a whole. Most importantly, this interpretation is unlikely to adversely affect the regulatory authority’s ability to make a statistically valid determination as to whether a diverse, effective permanent vegetative cover has been successfully established in accordance with the appropriate revegetation success standards. From a practical standpoint, it is usually difficult to identify precisely where such areas are located in the field once revegetation is established in accordance with the approved reclamation plan.708 establish on the regraded areas, and on all other lands affected, a diverse, effective, and permanent vegetation cover of the same seasonal variety native to the area of land to be affected and capable of self-regeneration and plant succession at least equal in extent of cover to the natural vegetation of the area; except, that introduced species may be used in the revegetation process where desirable and necessary to achieve the approved postmining land use plan[.] 39. Section 816.116: What are the standards for determining the success of revegetation? We propose to reorient our regulations concerning revegetation success standards away from focusing on a single postmining land use, which may or may not be implemented, to standards pertinent to a determination of whether the site has been restored ‘‘to a condition capable of supporting the uses which it was capable of supporting prior to any mining, or higher or better uses of which there is reasonable likelihood,’’ as required by section 515(b)(2) of SMCRA.709 In effect, the standards would have to reflect the premining land use capability and productivity information provided in the permit application in accordance Nothing in this provision of the Act suggests that revegetation success standards should be based solely or primarily on the postmining land use, with the exception of situations in which introduced species are desirable and necessary to achieve the postmining land use, as would be true of most cropland postmining land uses. Therefore, the approach most consistent with paragraphs (b)(2) and (b)(19) of section 515 of SMCRA 713 is the one that we are proposing; i.e., success standards that are sufficiently rigorous to demonstrate that the disturbed area has been restored to a condition capable of supporting the uses that it was capable of supporting before any mining and FR 55766 (Oct. 22, 1997). 709 30 U.S.C. 1265(b)(2). 19:15 Jul 24, 2015 711 S.

Proposed 30 CFR 816.116 would fill a gap in our existing rules by requiring the establishment of revegetation success standards for all reclaimed areas. Specifically, existing 30 CFR 816.116(b)(4) establishes revegetation success standards for lands with an approved commercial, industrial, or residential postmining land use only if that land use is to be implemented less than 2 years after completion of regrading. The existing rules are silent on revegetation success standards for lands with an approved commercial, industrial, or residential postmining land use to be implemented two or more years after completion of regrading. Proposed Paragraph (a) Proposed paragraph (a) is substantively identical to existing paragraph (a)(1). Proposed Paragraph (b) Proposed 30 CFR 816.116 would establish, or require the establishment of, revegetation success standards for all reclaimed areas. Proposed paragraph (b) would require that those standards be adequate to demonstrate restoration of premining land use capability, consistent with section 515(b)(2) of SMCRA.714 Specifically, revegetation success standards would have to be based upon the plant community and vegetation information required under proposed 30 CFR 779.19, the soil type and productivity information required under proposed 30 CFR 779.21, and the land use capability and productivity information required under proposed 30 CFR 779.22. Revegetation success standards also must be based upon the postmining land use approved under proposed 30 CFR 780.24 if the postmining land use will be implemented before expiration of the revegetation responsibility period. Otherwise, proposed paragraph (a)(4) would require that the site be revegetated in a manner that will restore native plant communities and the revegetation success standards for the site must reflect that requirement, regardless of the postmining land use. Proposed paragraph (a)(4) would improve implementation of section 515(b)(19) of SMCRA,715 which, with limited exceptions, requires revegetation with native species, and section 515(b)(24) of SMCRA,716 which requires that surface coal mining and reclamation operations minimize 714 30 U.S.C. 1265(b)(2).

Together with our proposed changes to the soil salvage and redistribution requirements in proposed 30 CFR 780.12(e) and 816.22, the revegetation success standard requirements of proposed paragraph (b) would preserve the site’s future land use capability in those situations in which the approved postmining land use is less intensive than other uses that the land was capable of supporting before mining. For example, if the approved postmining land use is pasture, but the land was used for cropland before mining, proposed 30 CFR 780.12(e) and 816.22 would require that the soil be reconstructed in a manner that would restore the site’s capability to support cropland (not just pasture, which does not require as deep a root zone). Similarly, proposed 30 CFR 816.116(b) would require that the revegetation success standards for the site be based in part upon row crop production, not just production of pasture forage and ground cover. Proposed Paragraph (c) Proposed paragraph (c) would require that revegetation success standards include species diversity, areal distribution of species, ground cover (except for land actually used for cropland after the completion of regrading and redistribution of soil materials), production (for land used for cropland, pasture or grazing land either before permit issuance or after the completion of regrading and redistribution of soil materials), and stocking (for all areas revegetated with woody plants, regardless of the postmining land use). Proposed paragraph (c) is intended to provide greater specificity than the introductory language of existing paragraph (a), which requires that the success of revegetation ‘‘be judged on the effectiveness of the vegetation for the approved postmining land use, the extent of cover compared to the cover occurring in natural vegetation of the area, and the general requirements of § 816.111.’’ Proposed paragraph (c) would be consistent with section 515(b)(19) of SMCRA,717 which requires establishment of ‘‘a diverse, effective, and permanent vegetative cover of the same seasonal variety native to the area of land to be affected and capable of self-regeneration and plant succession at 717 30 least equal in extent of cover to the natural vegetation of the area.’’ It also would be consistent with section 515(b)(2) of SMCRA,718 which requires restoration of the land ‘‘to a condition capable of supporting the uses that it was capable of supporting prior to any mining, or to higher or better uses * * *.’’ Proposed Paragraph (d) Proposed paragraph (d) is substantively identical to the second sentence of existing paragraph (a)(2), which establishes statistical confidence requirements for revegetation sampling techniques and statistical adequacy standards for determining when revegetation success standards for ground cover, production, and stocking have been met. We invite comment on whether our statistical confidence interval requirements are appropriate in all situations. 19:15 Jul 24, 2015 Proposed Paragraph (g) Proposed paragraph (g) is based upon existing paragraph (b)(4), which provides that areas to be developed for commercial, industrial, or residential use less than 2 years after completion of regrading need only meet a ground cover standard; i.e., the vegetative ground cover must not be less than that required to control erosion. Proposed paragraph (g) would revise this requirement to apply to all lands actually developed for commercial, industrial, or residential use during the revegetation responsibility period. This change would recognize the fact that vegetation and vegetative productivity are not major components of those land uses. However, because of the potential for abuse of this provision, the proposed rule would limit its applicability to only those lands actually developed for the specified uses, rather than all lands for which one of those uses has been approved as the postmining land use in the permit. Proposed Paragraph (f) Proposed paragraphs (f)(1) and (2) are substantively identical to existing paragraph (b)(3)(ii). However, proposed paragraph (f)(2)(iii)(A) would clarify that only those species of trees and shrubs approved in the permit as part of the revegetation plan under proposed 30 CFR 780.12(g) or volunteer trees and shrubs of species that meet the requirements of proposed 30 CFR 816.111(c) may be counted for purposes of determining whether stocking standards have been met. This proposed Proposed paragraph (h) is substantively identical to existing paragraph (b)(5) in that it specifies that, at a minimum, the cover on revegetated previously mined areas must not be less than the ground cover existing before redisturbance and must be adequate to control erosion. We also propose to clarify that previously mined areas need only meet a ground cover standard unless the regulatory authority specifies otherwise. The added language is consistent with the intent of the existing rule. 718 30 Jkt 235001 clarification is intended to ensure that only specimens of species consistent with section 515(b)(19) of SMCRA 719 are counted in determining revegetation success. Existing paragraph (b)(3)(iii) requires that vegetative ground cover on areas planted with trees and shrubs not be less than that required to achieve the approved postmining land use. Proposed paragraph (f)(3) would replace that requirement with a provision that would require that vegetative ground cover on areas planted with trees and shrubs have characteristics that will allow for the natural establishment and succession of native plants, including trees and shrubs. The preamble to proposed 30 CFR 816.111(b) discusses the significance of the extent and type of ground cover to the successful establishment of trees and shrubs. Proposed Paragraph (e) Proposed paragraph (e) is substantively identical to existing paragraph (b)(3)(i) in that it would require that the regulatory authority specify minimum stocking and planting arrangements on the basis of local and regional conditions and after coordination with and approval by the state agencies responsible for the administration of forestry and wildlife programs. However, unlike existing paragraph (b)(3)(i), which applies only to areas to be developed for fish and wildlife habitat, recreation, undeveloped land, or forest products, proposed paragraph (e) would apply to all areas that are revegetated with woody plants, consistent with proposed paragraph (c), as discussed in the preamble to proposed paragraph (b). We also propose to replace the term ‘‘consultation’’ with ‘‘coordination’’ to avoid any confusion with consultation requirements and procedures under section 7(a)(2) of the Endangered Species Act.

Section 816.133: What provisions concerning the postmining land use apply to my operation? We propose to revise existing paragraph (a) for clarity, to include cross-references to pertinent permitting requirements, and to add the phrase ‘‘of which there is a reasonable likelihood’’ after ‘‘higher or better uses’’ to be consistent with the corresponding statutory provision in section 515(b)(2) of SMCRA.720 Existing paragraphs (b) and (c) of this section are permitting requirements that we propose to move to the land use information requirements of 30 CFR 779.22 and the postmining land use requirements of 30 CFR 780.24.

Why are we proposing to remove the interpretive rule in existing 30 CFR 816.200? This section contains only one interpretive rule, which pertains to the 1979 version of the topsoil substitute requirements in 30 CFR 816.22. However, we revised 30 CFR 816.22 on May 16, 1983 (48 FR 22100), in a manner that rendered the interpretive rule obsolete. Therefore, we intend to remove existing 30 CFR 816.200. M. Part 817: Permanent Program Performance Standards—Underground Mining Activities. Part 817 contains the permanent regulatory program performance standards for underground mining activities. It is the counterpart to part 816 for surface mining activities. In general, part 817 is substantively identical to part 816, except for the substitution of ‘‘underground mining activities’’ for ‘‘surface mining activities,’’ the replacement of references to surface mining regulations with references to the corresponding underground mining regulations, and changes of a similar nature. Our proposed revisions to part 817 are similarly substantively identical to the corresponding revisions that we propose in part 816. Therefore, this portion of the preamble discusses only those proposed revisions to part 817 that differ from the proposed revisions to the corresponding provisions of part 816. Otherwise, the rationale that we provide for the proposed revisions to part 816 applies with equal effect to our proposed revisions to part 817. Section 516 of SMCRA 721 contains the performance standards for underground mining operations. Section 516(b)(10) 722 states that ‘‘with respect to other surface impacts not specified in this subsection * * *, [underground coal mining operations must] operate in accordance with the [performance] standards established under section 515 of this title for such effects which result from surface coal mining operations.’’ In other words, unless otherwise specified in section 516 or in the regulations implementing section 516, the performance standards for surface mining operations in section 515 of SMCRA 723 also apply to underground mining operations under section 516 of the Act. The following table identifies those provisions of section 515 for which section 516 contains a counterpart: Section 515(b) Section 516(b) (10) (11) (13) (14) (19) (21) (24) (9) (4) (5) (8) (6) (7) (11) In general, the corresponding provisions of sections 515 and 516 listed in the table are similar. Therefore, when reading the preamble to part 816 for purposes of understanding a rule proposed in part 817, you may use this table to convert references to section 515 in the preamble to part 816 to references to section 516 for purposes of part 817. 1. Section 817.11: What signs and markers must I post? The existing rules contain two requirements to mark buffer zones for perennial and intermittent streams—one in the stream buffer zone rules in sections 816.57(b) and 817.57(b) and one in the rules concerning signs and markers in sections 816.11(e) and 817.11(e). We propose to consolidate those requirements in sections 816.11(e) and 817.11(e). As revised, proposed section 817.11(e) provides that the boundaries of any buffer to be maintained between surface activities U.S.C. 1265(b)(2).

This section is substantively identical to proposed 30 CFR 816.34 for surface mines, with one exception: The underground rules do not contain a counterpart to proposed 30 CFR 816.34(a)(9), which would require that the permittee handle earth materials and runoff in a manner that will restore the approximate premining recharge capacity of the reclaimed area as a whole. Our omission of this provision from the underground mining rules reflects the construction of sections 515 and 516 of SMCRA.724 Section 515(b)(10)(D) of SMCRA 725 requires that surface coal mining operations restore the recharge capacity of the mined area to approximate premining conditions. However, that requirement does not appear in the corresponding provision for underground coal mining operations in section 516(b)(9) of SMCRA.726 3. Section 817.40: What responsibility do I have to replace water supplies? This section is substantively identical to proposed 30 CFR 816.40 for surface mines, with one exception: Proposed paragraph (a)(1) reflects the water supply replacement requirements of section 720(a)(2) of SMCRA 727 for underground mining operations rather than the water supply replacement requirements of section 717(b) of SMCRA 728 for surface mines. 4. Section 817.44: What restrictions apply to gravity discharges from underground mines? The counterpart to this proposed rule is existing 30 CFR 817.41(i). We propose to revise this rule by adding a requirement in proposed paragraph (a)(2)(ii) that the applicant for a gravity discharge design the discharge control structure to prevent a mine pool blowout. We also propose to add paragraph (a)(3), which would require that the permittee construct and maintain the discharge control structure in accordance with the design approved by the regulatory authority and any other conditions imposed by the regulatory authority.

Section 817.57: What additional performance standards apply to surface activities conducted in, through, or adjacent to a perennial or intermittent stream? This section is substantively identical to proposed 30 CFR 816.57 for surface mining activities except that, in accordance with our interpretation of the definition of ‘‘surface coal mining operations’’ in section 701(28) of SMCRA 730 and 30 CFR 700.5, the provisions of 30 CFR 817.57 would not apply to the surface impacts, including subsidence-related impacts, resulting from underground mining activities if there are no mining activities conducted on the surface of the land on which those impacts occur. However, as provided in the proposed definition of ‘‘material damage to the hydrologic balance outside the permit area’’ in 30 CFR 701.5, underground mine operators must conduct their operations in a manner that preserves sufficient flow to maintain existing and reasonably foreseeable uses of perennial and intermittent streams on land overlying the underground workings or within the angle of draw of those workings. In addition, as provided in the same definition, underground mine operators must conduct their operations in a manner that does not preclude attainment of the designated use or uses of perennial and intermittent streams on land overlying the underground workings or within the angle of draw of those workings. 6. Section 817.71: How must I dispose of excess spoil? We propose to remove existing 30 CFR 817.71(k), which provides that spoil resulting from face-up operations for underground coal mine development may be placed at drift entries as part of a cut-and-fill structure if that structure is less than 400 feet in length and is designed in accordance with section 817.71. We propose to remove this paragraph because spoil excavated as part of face-up operations and used to construct a mine bench is not excess spoil. Under both the existing and proposed definitions of excess spoil in 30 CFR 701.5, excess spoil consists of spoil material disposed of in a location 729 30 730 30 U.S.C. 1260(b)(3). U.S.C. 1291(28). VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 outside the mined-out area, but it does not include spoil needed to achieve restoration of the approximate original contour. In most cases, spoil used to construct the bench for an underground mine will later be used to reclaim the face-up area when coal extraction from the underground mine is finished. That is, the bench will be regraded to cover the mine entry and eliminate any highwall once mining is completed and the bench is no longer needed for mine offices, parking lots, equipment storage, conveyor belts, and other mining-related purposes. Consequently, this paragraph of the regulations does not belong in a section devoted to disposal of excess spoil. We are not proposing to move the requirements of 30 CFR 817.71(k) to another part of our rules because we do not find it necessary to impose the design requirements for excess spoil fills (which are permanent structures) on temporary spoil storage structures and support facilities, such as the benches to which section 817.71(k) applies. Nor do we find it necessary or appropriate to limit those benches to 400 feet in length. Bench length and configuration are more appropriately determined by operational, topographic, geologic, and other site-specific considerations. However, the regulatory authority has the right to impose design and construction requirements on a case-by-case basis when it determines that those requirements are a necessary prerequisite to making the permit application approval findings specified in 30 CFR 773.15. 7. Section 817.102: How must I backfill surface excavations and grade and configure the land surface? This section contains several differences from proposed 30 CFR 816.102 for surface mining activities. First, in paragraph (a), we propose to clarify that the backfilling requirement applies to surface excavations created by surface operations associated with underground mines. Second, the underground mining regulations would not include the exceptions for mountaintop removal mining and thin and thick overburden found in proposed 30 CFR 816.102(a)(1)(i), (iii), and (iv). Those provisions do not apply to underground mining operations. Third, we propose to move existing 30 CFR 817.102(l) to paragraph (a)(1)(vii) to consolidate it with the other exceptions to the requirement to restore the approximate original contour. We also propose to replace the word ‘‘fills’’ in the existing rule with ‘‘spoil storage areas’’ to comply more accurately with PO 00000 Frm 00143 Fmt 4701 Sfmt 4702 44577 the decision in In re: Permanent Surface Mining Regulation Litigation I, Round II (PSMRL I, Round II) when read as a whole.731 The opinion directs the Secretary to provide some flexibility for underground mining operations with respect to regrading spoil from face-up areas. The court’s opinion addresses the requirement to restore the approximate original contour for spoil stored until the underground mining operation is completed: One distinct difference between surface and underground mines concerns the length of their duration. An underground mine may remain active up to 40 years. Surface disturbances thereby become settled and revegetated. In this situation, it is duplicitous to require the removal of previously settled and revegetated land only to achieve the purpose of a second revegetation. The court therefore remands these regulations. It directs the Secretary to provide some flexibility for settled fills that have become stabilized and revegetated.732 The opinion does use the word ‘‘fills’’ in one instance in the last sentence of the opinion. However, we do not believe that the court intended its opinion to address excess spoil because excess spoil by definition includes only spoil not needed to restore the approximate original contour, which means that excess spoil fills already are excluded from the requirement to restore the approximate original contour. Therefore, applying this exception only to excess spoil fills would render the court’s decision meaningless. The court’s decision does not discuss the requirement in section 515(b)(3) of SMCRA 733 to eliminate all highwalls. We do not interpret the court’s decision as requiring an exception from that requirement. The court’s objection to the 1979 rule discusses situations in which the only purpose of removing and regrading spoil in a settled and revegetated storage area would be to restore the approximate original contour to achieve a second revegetation. However, removal of the stored spoil may be necessary for purposes other than revegetation. For example, the stored spoil may be needed to eliminate the highwall at the mine face-up. Therefore, we propose to add paragraph (a)(1)(vii)(G) to specify that settled and revegetated spoil storage areas may not be retained undisturbed if the spoil in those areas is needed to eliminate the 731 See In re: Permanent Surface Mining Regulation Litigation I-Round II, No. 79–1144, 1980 U.S. Dist.

Section 817.121: What measures must I take to prevent, control, or correct damage resulting from subsidence? We propose to revise paragraph (c)(4) of this section by removing those provisions that we suspended on December 22, 1999 (64 FR 71652– 71653), in response to a court order vacating those provisions.734 Specifically, we propose to remove all of existing 30 CFR 817.121(c)(4) except paragraph (c)(4)(v). We also propose to restructure this section for clarity and ease of reference and revise it in accordance with plain-language principles to make it more user-friendly. We do not propose any substantive revisions. 9. Why are we proposing to remove the interpretive rules in existing 30 CFR 817.200? Existing 30 CFR 817.200 contains two interpretive rules. The first one, in paragraph (c), pertains to the 1979 version of the topsoil substitute requirements in 30 CFR 817.22. However, we subsequently revised 30 CFR 817.22 in a manner that rendered the interpretive rule obsolete.735 Therefore, we intend to remove existing 30 CFR 817.200(c). The second interpretive rule, in paragraph (d), addresses the use of the permit revision process for postmining land use changes for underground mines. We propose to include this interpretive rule into 30 CFR 784.24 in revised form to the extent that it contains unique provisions not already present in other regulations. Specifically, proposed 30 CFR 784.24(c) would require that any proposed change to a higher or better postmining land use be processed as a significant permit revision. We will remove 30 CFR 817.200(d) if we adopt proposed 30 CFR 784.24(c). As discussed in the preamble to proposed 30 CFR 780.24(c), we propose to apply this requirement only to changes to higher or better uses rather than to all proposed land use changes because we also propose to revise our postmining land use regulations to clarify that the standards and procedures for approving alternative postmining land uses would apply only to changes to higher or better uses. Changes from one land use that the land was capable of supporting prior to mining to another land use that the land 734 Nat’l Mining Ass’n v. Babbitt, 173 F.3d 906 (D.C. Cir. 1999). 735 See 48 FR 22100 (May 16, 1983). VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 was capable of supporting prior to mining would no longer require approval as an alternative postmining land use. Our proposed revisions would improve consistency with section 515(b)(2) of SMCRA,736 which requires that surface coal mining and reclamation operations ‘‘restore the land affected to a condition capable of supporting the uses which it was capable of supporting prior to any mining, or higher or better uses of which there is a reasonable likelihood.’’ The statutory provision distinguishes only between uses that the land was capable of supporting before mining and higher or better uses; i.e., it establishes criteria for approval of higher or better uses, but no special criteria for approval of any of the uses that the land was capable of supporting before mining. N. Part 824: Special Permanent Program Performance Standards—Mountaintop Removal Mining Operations We propose to revise 30 CFR 824.11(a) by removing paragraphs (a)(2) through (a)(4) because they duplicate our proposed definition of mountaintop removal mining in 30 CFR 701.5. In addition, we propose to streamline the introductory language by specifying that 30 CFR 824.11 applies to all operations for which the regulatory authority has approved a permit under 30 CFR 785.14. Proposed paragraph (b)(1) would include existing 30 CFR 824.11(a)(5), which provides that mountaintop removal mining operations must meet all applicable requirements of the regulatory program except for approximate original contour restoration requirements. We propose to revise this paragraph by adding a citation to the approximate original contour restoration requirements in proposed 30 CFR 816.102(a)(1) and by adding an exception from the thick overburden requirements of 30 CFR 816.105. The latter requirements are inconsistent with the purpose of mountaintop removal mining operations, which is to create a level plateau or gently rolling contour, because the thick overburden rules require that as much spoil be returned to the mined-out area as possible. Under proposed paragraph (b)(2)(i), as under existing 30 CFR 824.11(a)(6), the permittee would be required to retain an outcrop barrier, consisting of the toe of the lowest coal seam and its associated overburden, of sufficient width to prevent slides and erosion, except for certain specified exceptions. We propose to revise this provision to require that the permittee construct drains through the barrier to the extent PO 00000 necessary to prevent saturation of the backfill. This requirement is necessary because the outcrop barrier resembles a berm but consists of consolidated natural rock and coal that is much less permeable than the fractured, unconsolidated rock of which backfill is comprised. Without drains, the barrier could serve as a dike, impounding water in the void spaces within the backfill. Allowing the foundation zone of the backfill to become saturated could result in slope instability, which would be inconsistent with section 102(a) of SMCRA,737 which states that one of the purposes of SMCRA is to ‘‘establish a nationwide program to protect society and the environment from the adverse effects of surface coal mining operations.’’ We also propose to add paragraph (b)(2)(iv) to allow the regulatory authority to approve removal of the outcrop barrier required by paragraph (b)(2)(i) if the regulatory program establishes standards for and requires construction of a barrier comprised of alternative materials that will provide equivalent stability. We have approved one such state program provision in West Virginia that has worked well, both in terms of stability and in terms of maximizing coal recovery consistent with section 515(b)(1) of SMCRA.738 In proposed paragraph (b)(3), which would include existing 30 CFR 824.11(a)(7), we propose to delete the phrase ‘‘on the mined area’’ from the language requiring final graded slopes to be no steeper than 20 percent. This revision would allow the plateau area to extend outside the mined area to include the decks (top surfaces) of excess spoil fills, which would be consistent with the concept of mountaintop removal mining and could facilitate the use of landforming principles if desired. In proposed paragraph (b)(4), which would include existing 30 CFR 824.11(a)(8), we propose to delete the existing sentence that prohibits directing drainage through or over a valley or head-of-hollow fill. This proposed revision would enhance the ability of the permittee to use landforming principles and natural stream channel design techniques when it is possible to do so without adversely impacting the stability of the fill and without increasing discharges of parameters of concern. Its adoption would allow the reestablishment or replacement of impacted or buried streams and facilitate the use of drainage techniques that incorporate the 737 30 736 30 U.S.C. 1265(b)(2).

We propose to move existing 30 CFR 824.11(a)(9), which prohibits damage to natural watercourses below the lowest coal seam to be mined, to 30 CFR 785.14(b)(9) in revised form. We propose to do so because this requirement is really more of an operational design element (permitting requirement) than a performance standard, especially in view of our proposed interpretation of the meaning of the underlying statutory provision as discussed in the preamble to proposed 30 CFR 785.14(b)(9). We propose to remove existing 30 CFR 824.11(a)(10), which requires that all waste and acid-forming and toxicforming materials be covered with nontoxic spoil to prevent pollution and to achieve the postmining land use. As discussed above, this provision is unnecessary because it contains no requirements that are not already encompassed by proposed 30 CFR 824.11(b)(1), which is the counterpart to existing 30 CFR 824.11(a)(5). tkelley on DSK3SPTVN1PROD with PROPOSALS2 O. Part 827: Special Permanent Program Performance Standards—Coal Preparation Plants Not Located Within the Permit Area of a Mine We propose to revise 30 CFR 827.12 by streamlining it to list only the sections of part 816 that apply to coal preparation plants not located at a mine. Specifically, this proposed rule would specify that the construction, operation, maintenance, modification, reclamation, and removal activities at coal preparation plants must comply with the following provisions of part 816: Sections 816.11, 816.22, 816.34 through 816.57, 816.71, 816.74, 816.79, 816.81 through 816.97, 816.100, 816.102, 816.104, 816.106, 816.111 through 816.116, 816.131 through 816.133, 816.150, 816.151, and 816.181. This list of sections is substantively identical to the sections included in the existing rule, with the exception that we propose to add 30 CFR 816.57 to the list. Section 816.57 contains performance standards for mining in, through, or within 100 feet of perennial and intermittent streams. In a previous rulemaking, we declined to include 30 CFR 816.57, which at that time was known as the stream buffer zone rule, in 30 CFR 827.12. However, we stated that we might add such a requirement ‘‘in a separate rulemaking if experience under this rule indicates that VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 such buffer zones are necessary to meet the Act’s objectives.’’ 739 Our experience over the last three decades has led us to propose inclusion of 30 CFR 816.57. Specifically, we find that coal preparation plants can have substantial and long-lasting adverse environmental impacts on streams as a result of dust, surface runoff, and noncompliant discharges of process water. In addition, coal preparation plants normally are in existence longer than a surface mine and some underground mines, which means that any impacts would be relatively longterm. An undisturbed buffer between coal preparation plants and streams could mitigate some of those impacts. X. What effect would this rule have in federal program states and on Indian lands? If adopted in final form, the rule that we are proposing today would apply to all non-Indian lands in states with a federal regulatory program. States with federal regulatory programs include Arizona, California, Georgia, Idaho, Massachusetts, Michigan, North Carolina, Oregon, Rhode Island, South Dakota, Tennessee, and Washington. These programs are codified at 30 CFR parts 903, 905, 910, 912, 921, 922, 933, 937, 939, 941, 942, and 947, respectively. In general, there would be no need to amend the approved federal program before the rule would take effect because, with limited exceptions, each program cross-references 30 CFR parts 700, 701, 773, 774, 777, 779, 780, 783, 784, 785, 800, 816, 817, 824, and 827. Tennessee is the only federal program state with active coal production and, thus, is the only state in which the rule would have immediate impact. Tennessee law already sharply restricts most significant mining activities in or near streams, which means that the provisions of proposed 30 CFR 780.28, 784.28, 816.57, and 817.57 pertaining to mining in, through, or near streams, are unlikely to have a significant effect on mining within that state. Section 69–3– 108(f) of the Tennessee Code Annotated, as amended by the Responsible Mining Act of 2009, prohibits issuance of any permit for the removal of coal by surface mining methods or for surface access points to underground mining within 100 feet of the ordinary high-water mark of a stream. It also prohibits issuance of a permit that would allow placement of overburden or waste from a surface mine within that buffer zone. However, unlike the proposed federal rule, the state law does not apply to any type of PO 00000 739 48 FR 20399 (May 5, 1983). Frm 00145 Fmt 4701 Sfmt 4702 44579 stream crossing, to operations that improve the quality of stream segments previously disturbed by mining, or to coal mine waste from underground mines or coal preparation plants. Nor does the state law apply to coal transportation, storage, preparation and processing, loading, and shipping operations when necessary because of site-specific conditions, provided that those activities and operations do not cause the loss of stream function. If adopted in final form, the following parts of the proposed rule that we are publishing today also would apply to Indian lands by virtue of crossreferences in 30 CFR part 750: • 30 CFR 750.12(c)(1) includes the permitting provisions of parts 773, 774, 777, 779, 780, 783, 784, and 785 by cross-reference. We are not proposing any substantive revisions to the exceptions listed in 30 CFR 750.12(c)(2). • 30 CFR 750.17 includes the bond and insurance provisions of subchapter J (part 800) by cross-reference. • 30 CFR 750.16 includes the performance standards of parts 816, 817, 824, and 827 by cross-reference. The revisions to parts 700 and 701 also would apply to Indian lands by virtue of 30 CFR 700.1(a), which provides that subchapter A of 30 CFR chapter VII contains ‘‘regulatory requirements and definitions generally applicable to the programs and persons covered by the Act.’’ We invite the public to comment on whether there are unique conditions in any federal program states or on Indian lands that should be addressed in the national rule or as specific amendments to individual federal programs or to the Indian lands rules. XI. How would this rule affect state regulatory programs? Adoption of this proposed rule as a final rule would not have any immediate effect on approved state regulatory programs. States would need to propose and adopt counterpart revisions to their regulations and other state program provisions and submit them for review by OSMRE and the public as a program amendment under 30 CFR 732.17. Under 30 CFR 732.17(g)(9), no change to state law or regulations shall take effect for purposes of a state program until that change is approved by OSMRE as a program amendment. If we adopt a final rule based on this proposed rule, we will evaluate each state regulatory program approved under 30 CFR part 732 and section 503 E:\FR\FM\27JYP2.SGM 27JYP2 44580 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules of the Act 740 to determine whether any changes in the state program are necessary to maintain consistency with federal requirements. If we determine that a state program provision needs to be amended as a result of revisions to the corresponding federal rule, we will notify the state in accordance with 30 CFR 732.17(d). Section 505(a) of the Act 741 and 30 CFR 730.11(a) provide that SMCRA and federal regulations adopted under SMCRA do not supersede any state law or regulation unless that law or regulation is inconsistent with the Act or the federal regulations adopted under the Act. Section 505(b) of the Act 742 and 30 CFR 730.11(b) provide that we may not construe existing state laws and regulations, or state laws and regulations adopted in the future, as inconsistent with SMCRA or the federal regulations if these state laws and regulations either provide for more stringent land use and environmental controls and regulations or have no counterpart in the Act or the federal regulations. Under 30 CFR 732.15(a), each state regulatory program must provide for the state to carry out the provisions and meet the purposes of the Act and its implementing regulations. In addition, that rule requires that state laws and regulations be in accordance with the provisions of the Act and consistent with the federal regulations. As defined in 30 CFR 730.5, ‘‘consistent with’’ and ‘‘in accordance with’’ mean that the state laws and regulations are no less stringent than, meet the minimum requirements of, and include all applicable provisions of the Act. The definition also provides that these terms mean that the state laws and regulations are no less effective than the federal regulations in meeting the requirements of the Act. Under 30 CFR 732.17(e)(1), we may require a state program amendment if, as a result of changes in SMCRA or the federal regulations, the approved state regulatory program no longer meets the requirements of SMCRA or the federal regulations. tkelley on DSK3SPTVN1PROD with PROPOSALS2 XII.

XIII. Procedural Matters and Required Determinations A. Regulatory Planning and Review (Executive Orders 12866 and 13563) Executive Order 12866 provides that the Office of Information and Regulatory E:\FR\FM\27JYP2.SGM 27JYP2 tkelley on DSK3SPTVN1PROD with PROPOSALS2 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules Affairs (OIRA) will review all significant rules. OIRA has determined that this proposed rule is significant because it may have an annual effect on the economy of $100 million or more, or adversely affect in a material way the economy, a sector of the economy, productivity, competition, jobs, the environment, public health, or safety, or State, local or tribal governments or communities. Executive Order 13563 reaffirms the principles of E.O. 12866 while calling for improvements in the Nation’s regulatory system to promote predictability, to reduce uncertainty, and to use the best, most innovative, and least burdensome tools for achieving regulatory ends. The executive order directs agencies to consider regulatory approaches that reduce burdens and maintain flexibility and freedom of choice for the public where these approaches are relevant, feasible, and consistent with regulatory objectives. E.O. 13563 emphasizes further that regulations must be based on the best available science and that the rulemaking process must allow for public participation and an open exchange of ideas. We have developed this proposed rule in a manner consistent with these requirements. We have prepared a draft regulatory impact analysis (RIA) and submitted it to the Office of Management and Budget. We invite comments on that analysis, which you can view online at www.osmre.gov and www.regulations.gov or in person at the headquarters office location listed in ADDRESSES and at the OSMRE regional, field, and area office locations listed in Part XII of this preamble. Based upon the draft RIA, we do not project that the proposed rule would prohibit mining of any particular coal reserves in excess of baseline conditions. Therefore, our estimates do not include the direct and indirect costs associated with stranded coal reserves. We invite comment on the occurrence of stranded coal reserves as a consequence of the proposed rule and any attendant costs that should be included in the RIA. We also invite comment on the cost assumptions by model mine and alternative in Exhibit 4–3 in the draft RIA, including the assumed costs for habitat restoration. estimates into their assessments of regulatory impacts in cost-benefit analyses.743 The Interagency Working Group guidance provides an SCC dollar value based on the average of three specific models. The SCC related to a specific proposed action is calculated by multiplying the change in emissions in that year by the SCC value appropriate for that year. The net present value of the benefits can be calculated by multiplying each of these future benefits by an appropriate discount factor and summing across all affected years. This analysis does not monetize the methane emissions and increased carbon sequestration effects of the action alternatives in the draft EIS for multiple reasons. Most fundamentally, data limitations prevent a quantitative analysis of the net effect of each alternative on carbon emissions from coal mining. Available evidence suggests that the alternatives would have varying offsetting effects on greenhouse gas emissions. For instance, some alternatives would result in changes that would increase emissions, such as an increase in the amount of time hauling vehicles are operated. Conversely, some of the same alternatives would increase the number of acres of forest reestablished or undisturbed annually, which would increase the carbon storage potential when compared to the No Action Alternative. Predicting the direction and magnitude of impacts on overall U.S. greenhouse gas emissions is highly complex. The impact depends on factors such as the change in coal prices, the technological flexibility that power producers have to switch to substitute fuels, the price trends for those substitutes, the emissions profile for those substitutes, changes in coal export markets, and a variety of other considerations. This analysis anticipates that the net effect on climate resiliency is positive at the national level under each action alternative (excluding Alternative 9), i.e., that each alternative would result in less carbon in the atmosphere because of increased carbon sequestration and reduced methane emissions. However, data gaps prevent quantifying, and therefore monetizing, the magnitude of this benefit. Social Cost of Carbon (SCC) The Interagency Working Group on the Social Cost of Carbon issued guidelines in 2010, and an update in 2013, to help agencies assess the climate change-related benefits of reducing carbon emissions and integrate these 743 Technical Support Document—Technical Update of the Social Cost of Carbon for Regulatory Impact Analysis Under Executive Order 12866, Interagency Working Group on Social Cost of Carbon, United States Government, May 2013.

When a federal agency proposes regulations, the RFA, as amended by the Small Business Regulatory Enforcement Fairness Act of 1996 (SBREFA), requires the agency to prepare and make available for public comment an analysis that describes the effect of the rule on small businesses, small organizations, and small government jurisdictions.744 For this rulemaking, the analysis takes the form of an Initial Regulatory Flexibility Analysis (IRFA), which appears in Appendix A of the draft regulatory impact analysis. Estimate of the Number of Small Entities to Which the Rule Would Apply The goal of this analysis is to identify the number of small entities with mining permits that fall within each coal region. However, due to the complexity in corporate structures in the coal mining industry, it is difficult to calculate the exact number of small entities (defined by the RFA as having 500 or fewer employees) that could be affected by this proposed rule. The coal mining industry is continually changing and it is common for large mining operators to merge with smaller operators, creating complicated business relationships between parent corporations and subsidiaries. When determining how to estimate the number of small coal mining companies that could be affected by the proposed rule, we used a conservative approach to avoid underestimating the number of small entities. Specifically, we adhered to the method that the Mine Safety and Health Administration (MSHA) uses to calculate compliance costs to small business. MSHA examines the impact of a proposed rule on a mine with 500 or fewer employees, which is the Small Business Administration (SBA) threshold, and gives careful consideration to small mines with fewer than 20 employees. MSHA’s rationale for applying these two thresholds is as follows: MSHA has also examined the impact of the proposed rule on mines with fewer than 20 employees, which MSHA and the mining community have traditionally referred to as ‘‘small mines.’’ These small mines differ from larger mines not only in the number of employees, but also in economies of scale in material produced, in the type and amount of production equipment, and in supply inventory. Therefore, their costs of complying with MSHA’s rules and the impact of the Agency’s rules on them would also tend to be different. This analysis complies with the requirements of the RFA for an analysis of the impact on ‘‘small 744 5 E:\FR\FM\27JYP2.SGM U.S.C. 601 et seq. 27JYP2 44582 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules entities’’ while continuing MSHA’s traditional definition of ‘‘small mines.’’ 745 To estimate the number of small entities potentially affected by this rule, we used MSHA data from 2013 on mines, mine controllers, employees, and production to identify mines likely operated by small businesses. We assumed that each mine controller listed in that database represented a separate entity. We eliminated controllers with more than 500 employees. We also excluded all inactive mines, all operating companies reporting no employees, and all entities reporting less than 2,000 tons annual production because these mines are not representative of a typical small entity in the industry. We sorted small entities into those with identified controllers having 500 or fewer employees (the SBA threshold), and, as a subset, those controllers having fewer than 20 employees (the MSHA threshold). We determined that there were 284 small entities under the SBA threshold and 134 small entities under MSHA’s small mine definition, with 91 percent of the SBA small entities and 96 percent of the MSHA small mines located in the Appalachian Basin. We estimate that compliance costs for SBA small entities would range between zero and 3.6 percent of gross annual revenues, depending on the mining region. In Appalachia, we estimate compliance costs would average 4.7 percent of gross annual revenues for surface mines and 2.5 percent of gross annual revenues for underground mines. We estimate that compliance costs for MSHA small mines would range between 0 and 16 percent of gross annual revenues, depending on the mining region. In Appalachia, we estimate compliance costs would average 7.1 percent of gross annual revenues for surface mines and 4.3 percent of gross annual revenues for underground mines. tkelley on DSK3SPTVN1PROD with PROPOSALS2 Description of Measures to Minimize Economic Impacts on Small Entities Section 507(c) of SMCRA 746 establishes the small operator assistance program (SOAP).

An operator is eligible to receive training and assistance if his or her probable total annual production at all locations will not exceed 300,000 tons. Under section 507(c)(1) of SMCRA 747 and 30 CFR 795.9, the following permit application activities are eligible for financial assistance under SOAP: • Preparation of the determination of the probable hydrologic consequences of mining, including collection and analysis of baseline data and any engineering analyses and designs needed for the determination. • Collection and analysis of geological data. • Development of cross-sections, maps, and plans. • Collection of information on archaeological and historical resources and preparation of any related plans. • Development of preblast surveys. • Collection of site-specific information on fish and wildlife resources and preparation of fish and wildlife protection and enhancement plans. These activities include many of the new permit application requirements in the proposed rule; e.g., the expanded baseline data requirements concerning hydrology, geology, and the biological condition of streams and the expanded requirements for site-specific fish and wildlife protection and enhancement plans. In addition, section 507(c)(2) of SMCRA 748 provides that, as part of SOAP, we must either provide training or assume the cost of training eligible small operators on the preparation of permit applications and compliance with the regulatory program. Although SOAP funding is available for activities associated with new permit application requirements and training, SMCRA does not authorize SOAP funding for compliance costs associated with the expanded requirements for monitoring groundwater, surface water, and the biological condition of streams. If this proposed rule is adopted as a final rule, we intend to interpret section 507(c)(1) of SMCRA 749 in a manner that will maximize SOAP funding eligibility for the cost of compliance with the new permit application requirements. We invite comment on whether 30 CFR 795.9 could or should be revised to include more of the new permit application requirements in this proposed rule. PO 00000 U.S.C. 1257(c)(1). U.S.C. 1257(c)(2). 749 30 U.S.C. 1257(c)(1). SOAP funding is subject to annual appropriation from the federal expense portion of the Abandoned Mine Reclamation Fund established under section 401(a) of SMCRA.750 Section 401(c)(9) of SMCRA 751 caps SOAP funding at $10 million per year. If this proposed rule is adopted, we intend to request $10 million in appropriations to provide financial assistance to small operators in developing permit applications. We also intend to provide training to assist small operators in meeting the additional requirements of the proposed rule. Thus, SOAP assistance should substantially reduce compliance costs for small operators by offsetting the cost of most of the new permit application requirements. C. Small Business Regulatory Enforcement Fairness Act This proposed rule is not a major rule under the Small Business Regulatory Enforcement Fairness Act, 5 U.S.C. 804(2). As discussed in the draft regulatory impact analysis, the proposed rule would not— a. Have an annual effect on the economy of $100 million or more. b. Cause a major increase in costs or prices for consumers; individual industries; federal, state, or local government agencies; or geographic regions. c. Have significant adverse effects on competition, employment, investment, productivity, innovation, or the ability of U.S.-based enterprises to compete with foreign-based enterprises. D. Unfunded Mandates This proposed rule would not impose an unfunded mandate on state, local, or tribal governments or the private sector of $100 million or more per year. As discussed in the draft regulatory impact analysis, the total aggregate annual compliance and related costs associated with this proposed rule would not exceed $60 million. In addition, the proposed rule would not have a significant or unique effect on state, tribal, or local governments or the private sector. Therefore, a statement containing the information required by the Unfunded Mandates Reform Act, 2 U.S.C. 1534, is not required. E. Executive Order 12630—Takings Under the criteria in Executive Order 12630, we have made a preliminary determination that this proposed rule does not have specific, identifiable takings implications. First, based upon the draft regulatory impact analysis, we 747 30 748 30 Frm 00148 Fmt 4701 750 30 751 30 Sfmt 4702 E:\FR\FM\27JYP2.SGM U.S.C. 1231(a).

Second, the question of whether the proposed rule might effect a compensable taking of a particular property interest necessarily involves ad hoc factual inquiries, including the economic impact of the proposed rule on a particular claimant; the extent to which the proposed rule might interfere with a claimant’s reasonable, investment-backed expectations; and the character of the government action, none of which is possible for a national rule of this scope, which does not specifically bar the mining of any particular coal reserves. However, based upon the draft regulatory impact analysis, we have no basis to believe that implementation of the proposed rule would be likely to result in compensable takings of any specific property interests. F. Executive Order 13132—Federalism This proposed rule would not alter or affect the relationship between states and the federal government. Therefore, the proposed rule does not have significant federalism implications. Consequently, there is no need to prepare a federalism assessment. tkelley on DSK3SPTVN1PROD with PROPOSALS2 G. Executive Order 12988—Civil Justice Reform The Office of the Solicitor for the Department of the Interior has determined that this proposed rule would not unduly burden the judicial system and that it meets the requirements of sections 3(a) and 3(b)(2) of the Executive Order. H. Executive Order 13175— Consultation and Coordination With Indian Tribal Governments We have evaluated the potential effects of this proposed rule on federally-recognized Indian tribes and have determined that its provisions would not have substantial direct effects on the relationship between the federal government and Indian tribes or on the distribution of power and responsibilities between the federal government and Indian tribes. On May 12, 2010, the Director of OSMRE met with the Chairmen of the Hopi and Crow Tribes and the President of the Navajo Nation to initiate consultation on the stream protection rulemaking and development of the draft EIS. The tribes in attendance requested that they be kept informed of the rulemaking process and EIS development. The Director of OSMRE again met with tribal leaders in Washington, DC on December 1, 2011. At that time, OSMRE provided VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 additional information on the elements under consideration for the alternatives in the draft EIS and discussed the expected impacts to the SMCRA regulatory program for Indian lands. OSMRE intends to consult with tribal leaders again after the proposed rule has been published. I. Executive Order 13211—Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use This proposed rule is not considered a significant energy action under Executive Order 13211. As discussed below and in the draft regulatory impact analysis, the revisions contained in this proposed rule would not have a significant effect on the supply, distribution, or use of energy. The Office of Management and Budget has identified nine outcomes that may constitute ‘‘a significant adverse effect.’’ The three outcomes that are relevant to this proposed rule are: (1) A reduction in coal production in excess of five million tons per year, (2) a reduction in electricity production in excess of one billion kilowatt-hours per year or in excess of 500 megawatts (MW) of installed capacity,752 and (3) an increase in the cost of energy production in excess of one percent. As explained below, the proposed rule would not meet any of these criteria. The draft regulatory impact analysis estimates the impact of the proposed rule on coal production over a 21-year period, 2020 through 2040. On average, the rule would reduce coal production by 1.9 million short tons per year, with the greatest impact occurring in 2022, when the reduction would be 4.6 million short tons. Because coal makes up a significant part of the domestic energy mix, an increase in the price of coal likely would result in an increase in domestic electricity prices, which in turn would reduce market demand for electricity. The draft regulatory impact analysis predicts that the proposed rule would increase electricity costs by 0.1 percent per year on average, which would result in an average decrease in electricity demand and production of 0.2 billion kilowatt-hours per year. Compliance costs associated with the proposed rule would be less than one percent of total coal production costs in every year within the study period (2020–2040). On average, compliance 752 Installed capacity is the ‘‘total manufacturerrated capacity for equipment such as turbines, generators, condensers, transformers, and other system components’’ and represents the maximum flow of energy from the plant or the maximum output of the plant. PO 00000 Frm 00149 Fmt 4701 Sfmt 4702 44583 costs would comprise 0.1 percent of total coal production costs over that period. J. Paperwork Reduction Act Under 5 CFR 1320, the rules implementing the information collection aspects of the Paperwork Reduction Act, a federal agency must estimate the burden imposed on the public by any proposed collection of information. This burden consists of ‘‘the total time, effort, or financial resources expended by persons to generate, maintain, retain, or disclose or provide information to or for a Federal agency.’’ We estimated the aggregate burden (in hours) for information collection under the proposed rule by calculating the number of hours that industry and state and local governments would need to comply with each element of the proposed rule. In addition, we estimated the total annual non-hour cost burden to respondents. These non-wage costs include items such as equipment required for monitoring, sampling, drilling and testing, operation and maintenance, and purchase of services. We calculated the total estimated burden for two respondent groups, mine operators and state regulatory authorities, on an annual basis averaged over a 3-year period. Summary of Burden (Costs) Calculated for Major Elements of Stream Protection Rule This proposed rule contains collections of information that we are submitting to the Office of Management and Budget (OMB) for review and approval in accordance with the Paperwork Reduction Act, 44 U.S.C. 3501, et seq. These collections are contained in 30 CFR parts 774, 779, 783, 780, 784, 785, 800, 816, and 817. We also estimated programmatic changes where burden is being moved between parts.

Summary: Sections 506, 507, 509, 510, and 511 of SMCRA provide that persons seeking permit revisions, permit renewals; or the transfer, assignment, or sale of their permit rights for coal mining activities submit relevant information to the regulatory authority to allow the regulatory authority to determine whether the applicant meets the requirements for the action requested.

Title: 30 CFR part 780—Surface Mining Permit Applications—Minimum Requirements for Operation and Reclamation Plans. OMB Control Number: 1029–xxx3. Summary: Sections 507 and 508 of the Act contain permit application requirements for surface coal mining activities, including a requirement that the application include an operation and reclamation plan. The regulatory authority uses this information to determine whether the proposed surface coal mining operation will achieve the environmental protection requirements of the Act and regulatory program. Without this information, OSMRE and state regulatory authorities could not approve permit applications for surface coal mines and related facilities. Title: 30 CFR part 784—Underground Mining Permit Applications—Minimum Requirements for Operation and Reclamation Plans. OMB Control Number: 1029–xxx4. Summary: Sections 507(b), 508(a), and 516(b) and (d) of SMCRA require applicants for permits for underground coal mines to prepare and submit operation and reclamation plans for coal mining activities as part of the application. Regulatory authorities use this information to determine whether the plans will achieve the reclamation and environmental protection requirements of the Act and regulatory program. Without this information, OSMRE and state regulatory authorities could not approve permit applications for underground coal mines and related facilities. Title: 30 CFR part 785—Requirements for Permits for Special Categories of Mining. OMB Control Number: 1029–xxx5. Summary: Sections 507, 508, 510, 515, 701, and 711 of SMCRA require applicants for special categories of mining activities to provide descriptions, maps, plans and data relating to the proposed activity. Without this information, OSMRE and state regulatory authorities could not approve permit applications for special categories of mining activities. Title: 30 CFR part 800—Bond, Financial Assurance, and Insurance Requirements for Surface Coal Mining and Reclamation Operations Under Regulatory Programs. OMB Control Number: 1029–xxx6. Estimated annual responses Estimated burden hour changes due to SPR Summary: OSMRE and state regulatory authorities use the information collected under 30 CFR part 800 to ensure that persons conducting or planning to conduct surface coal mining and reclamation operations post and maintain a performance bond or financial assurance in a form and amount adequate to guarantee fulfillment of all reclamation obligations. Title: 30 CFR parts 816 and 817— Permanent Program Performance Standards—Surface and Underground Mining Activities. OMB Control Number: 1029–xxx7. Summary: Sections 515 and 516 of SMCRA provide that permittees conducting coal mining and reclamation operations must meet all applicable performance standards of the regulatory program approved under the Act. The regulatory authority uses the information collected to assist in evaluating compliance with this requirement.

The area outside the proposed or actual permit area within which there is a reasonable possibility of adverse impacts from surface coal mining operations or underground mining activities, as determined by the regulatory authority. The area covered by this term will vary with the context in which a regulation uses this term; i.e., the nature of the resource or resources addressed by a regulation in which the term ‘‘adjacent area’’ appears will determine the size and other dimensions of the adjacent area for purposes of that regulation. (b) Underground mines. For underground mines, the adjacent area includes, at a minimum, the area overlying the underground workings plus the area within a reasonable angle of draw from the perimeter of the underground workings. (c) Underground mine pools. For all operations, the adjacent area also includes the area that might be affected physically or hydrologically by the dewatering of existing mine pools as part of surface or underground mining operations, plus the area that might be affected physically or hydrologically by mine pools that develop after cessation of mining activities. * * * * * Approximate original contour means that surface configuration achieved by backfilling and grading of the mined area so that the reclaimed area closely resembles the general surface configuration of the land within the permit area prior to any mining activities or related disturbances and blends into and complements the E:\FR\FM\27JYP2.SGM 27JYP2 tkelley on DSK3SPTVN1PROD with PROPOSALS2 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules drainage pattern of the surrounding terrain. All highwalls and spoil piles must be eliminated to meet the terms of the definition, but that requirement does not prohibit the approval of terracing under § 816.102 or § 817.102 of this chapter, the retention of access roads in accordance with § 816.150 or § 817.151 of this chapter, or the approval of permanent water impoundments that comply with §§ 816.49, 816.56, and 780.24(b) or §§ 817.49, 817.56, and 784.24(b) of this chapter. For purposes of this definition, the term ‘‘mined area’’ does not include excess spoil fills and coal refuse piles. * * * * * Backfill, when used as a noun, means the spoil and waste materials used to fill the void resulting from an excavation created for the purpose of extracting coal from the earth. When used as a verb, the term refers to the process of filling that void. The term also includes all spoil and waste materials used to restore the approximate original contour. Bankfull means the water level, or stage, at which a stream, river, or lake is at the top of its banks and any further rise would result in water moving into the flood plain. * * * * * Biological condition is a measure of the ecological health of a stream or segment of a stream as determined by the type, diversity, distribution, abundance, and physiological state of aquatic organisms and communities found in the stream or stream segment. * * * * * Cumulative impact area means an area that includes the— (a) Actual or proposed permit area. (b) HUC–12 (U.S. Geological Survey 12-digit Watershed Boundary Dataset) watershed or watersheds in which the actual or proposed permit area is located. (c) Any other area within which impacts resulting from an actual or proposed surface or underground coal mining operation may interact with the impacts of all existing and anticipated surface and underground coal mining on surface-water and groundwater systems, including the impacts that existing and anticipated mining will have during mining and reclamation and after final bond release. At a minimum, existing and anticipated mining must include: (1) The proposed operation; (2) All existing surface and underground coal mining operations; (3) Any proposed surface or underground coal mining operation for which a permit application has been submitted to the regulatory authority; VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 (4) Any proposed surface or underground coal mining operation for which a request for an authorization, certification, or permit has been submitted under the Clean Water Act; (5) All existing and proposed coal mining operations that are required to meet diligent development requirements for leased federal coal and for which a resource recovery and protection plan has been either approved or submitted to and reviewed by the authorized officer of the Bureau of Land Management under 43 CFR 3482.1(b); and (6) For underground mines, all areas of contiguous coal reserves adjacent to an existing or proposed underground mine that are owned or controlled by the applicant. * * * * * Ecological function of a stream means the role that the stream plays in dissipating energy and transporting water, sediment, organic matter, and nutrients downstream. It also includes the ability of the stream ecosystem to retain and transform inorganic materials needed for biological processes into organic forms (forms containing carbon) and to oxidize those organic molecules back into elemental forms through respiration and decomposition. Finally, the term includes the role that the stream plays in the life cycles of plants, insects, amphibians (especially salamanders), reptiles, fish, birds, and mammals that either reside in the stream or depend upon it for habitat, reproduction, food, water, or protection from predators. The biological condition of a stream is one measure of its ecological function. * * * * * Ephemeral stream means a stream or part of a stream that has flowing water only during, and for a short duration after, precipitation events in a typical year. Ephemeral streambeds are located above the water table year-round. Groundwater is not a source of water for streamflow. Runoff from rainfall is the primary source of water for streamflow. * * * * * Excess spoil means spoil material disposed of in a location other than the mined-out area within the permit area and all spoil material placed above the approximate original contour within the mined-out area as part of the continued construction of an excess spoil fill with a toe located outside the mined-out area. This term does not include any spoil required and used to restore the approximate original contour of the mined-out area. Except as provided in the first sentence of this definition, this term does not include spoil material PO 00000 Frm 00153 Fmt 4701 Sfmt 4702 44587 placed within the mined-out area in accordance with the thick overburden provisions of § 816.105(b)(1) of this chapter. Nor does it include spoil material used to blend the mined-out area with the surrounding terrain in non-steep slope areas in accordance with § 816.102(b)(3) or § 817.102(b)(3) of this chapter. * * * * * Fill means a permanent, nonimpounding structure constructed under §§ 816.71 through 816.83 or §§ 817.71 through 817.83 of this chapter for the purpose of disposing of excess spoil or coal mine waste generated by surface coal mining operations or underground mining activities. * * * * * Groundwater means subsurface water located in those portions of soils and geologic formations that are fully saturated with water; i.e., those zones where all the pore spaces and rock fractures are completely filled with water. This term includes subsurface water in both regional and perched aquifers, but it does not include water in soil horizons that are temporarily saturated by precipitation events. * * * * * Hydrologic balance means the relationship between the quality and quantity of water inflow to, water outflow from, and water storage in a hydrologic unit such as a drainage basin, aquifer, soil zone, lake, or reservoir. It encompasses the dynamic relationships among precipitation, runoff, evaporation, and changes in storage of groundwater and surface water, as well as interactions that result in changes in the chemical composition or physical characteristics of groundwater and surface water, which may in turn affect the biological condition of streams and other water bodies. * * * * * Intermittent stream means a stream or part of a stream that has flowing water during certain times of the year when groundwater provides water for streamflow. During dry periods, intermittent streams may not have flowing water. Runoff from rainfall is a supplemental source of water for streamflow. * * * * * Land use means specific uses or management-related activities, rather than the vegetation or cover of the land. The term includes support facilities that are an integral part of the use. Land uses may be identified in combination when joint or seasonal uses occur. For purposes of this chapter, the following land use categories apply: E:\FR\FM\27JYP2.SGM 27JYP2 tkelley on DSK3SPTVN1PROD with PROPOSALS2 44588 Federal Register / Vol. 80, No. 143 / Monday, July 27, 2015 / Proposed Rules (a) Cropland. Land used for the production of crops for harvest, either alone or in rotation with grasses and legumes. Crops include row crops, small grains, hay, commercial nursery plantings, vegetables, fruits, nuts, crops, and other plants typically cultivated for commercial purposes in fields, orchards, vineyards, and similar settings. * * * * * Material damage, in the context of §§ 784.30 and 817.121 of this chapter, means: (a) Any functional impairment of surface lands, features, structures or facilities; (b) Any physical change that has a significant adverse impact on the affected land’s capability to support any current or reasonably foreseeable uses or causes significant loss in production or income; or (c) Any significant change in the condition, appearance or utility of any structure or facility from its presubsidence condition. Material damage to the hydrologic balance outside the permit area means any adverse impact from surface coal mining and reclamation operations or from underground mining activities, including any adverse impacts from subsidence that may occur as a result of underground mining activities, on the quality or quantity of surface water or groundwater, or on the biological condition of a perennial or intermittent stream, that would— (a) Preclude any designated use under sections 101(a) or 303(c) of the Clean Water Act or any existing or reasonably foreseeable use of surface water or groundwater outside the permit area; or (b) Impact threatened or endangered species, or have an adverse effect on designated critical habitat, outside the permit area in violation of the Endangered Species Act of 1973, 16 U.S.C. 1531 et seq. * * * * * Mountaintop removal mining means surface mining activities in which the mining operation extracts an entire coal seam or seams running through the upper fraction of a mountain, ridge, or hill, except for outcrop barriers retained under § 824.11(b)(2) of this chapter, by removing substantially all overburden above the coal seam and using that overburden to create a level plateau or a gently rolling contour, with no highwalls remaining, that is capable of supporting one or more of the postmining land uses identified in § 785.14 of this chapter. * * * * * VerDate Sep<11>2014 19:15 Jul 24, 2015 Jkt 235001 Occupied residential dwelling and structures related thereto means, for purposes of §§ 784.30 and 817.121 of this chapter, any building or other structure that, at the time the subsidence occurs, is used either temporarily, occasionally, seasonally, or permanently for human habitation. This term also includes any building, structure, or facility installed on, above, or below the land surface if that building, structure, or facility is adjunct to or used in connection with an occupied residential dwelling. Examples of such structures include, but are not limited to, garages; storage sheds and barns; greenhouses and related buildings; utilities and cables; fences and other enclosures; retaining walls; paved or improved patios, walks and driveways; septic sewage treatment facilities; and lot drainage and lawn and garden irrigation systems. This term does not include any structure used only for commercial agricultural, industrial, retail or other commercial purposes. * * * * * Parameters of concern means those chemical or physical characteristics and properties of surface water or groundwater that could be altered by surface or underground mining activities, including discharges associated with those activities, in a manner that would adversely impact surface-water or groundwater quality or the biological condition of a stream. Perennial stream means a stream or part of a stream that has flowing water year-round during a typical year. The water table is located above the streambed for most of the year. Groundwater is the primary source of water for streamflow. Runoff from rainfall is a supplemental source of water for streamflow. * * * * * Reclamation means those actions taken to restore mined land and associated disturbed areas to a condition in which the site is capable of supporting the uses it was capable of supporting prior to any mining or any higher or better uses approved by the regulatory authority. The site also must meet all other requirements of the permit and regulatory program that pertain to restoration of the site. For sites with discharges that require treatment, this term also includes those actions taken to eliminate, remediate, or treat those discharges, including both discharges from the mined area and all other discharges that are hydrologically connected to either the mined area or the operation, regardless of whether PO 00000 Frm 00154 Fmt 4701 Sfmt 4702 those discharges are located within the disturbed area. Reclamation plan means the plan for reclamation of surface coal mining operations under parts 780, 784, and 785 of this chapter. * * * * * Renewable resource lands means aquifers, aquifer recharge areas, recharge areas for other subsurface and surface water, areas for agricultural or silvicultural production of food and fiber, and grazing lands. Replacement of water supply means, with respect to protected water supplies contaminated, diminished, or interrupted by coal mining operations, provision of water supply on both a temporary and permanent basis equivalent to premining quantity and quality. Replacement includes provision of an equivalent water delivery system and payment of operation and maintenance costs in excess of customary and reasonable delivery costs for premining water supplies. * * * * * Temporary diversion means a channel constructed to convey streamflow or overland flow away from the site of actual or proposed coal exploration or surface coal mining and reclamation operations or to convey those flows to a siltation structure or other treatment facility. The term includes only those channels not approved by the regulatory authority to remain after reclamation as part of the approved postmining land use. * * * * * Waters of the United States has the same meaning as the definition of that term in 40 CFR 230.3(s). * * * * * PART 773—REQUIREMENTS FOR PERMITS AND PERMIT PROCESSING 5.

(iv) The proposed operation will result in a lesser adverse impact on the aquatic ecology of the cumulative impact area than would occur if the area to be mined was restored to its approximate original contour. (v) The impact on perennial and intermittent streams within the proposed permit and adjacent areas will be less than the impact that would occur if the area to be mined was restored to its approximate original contour. The fish and wildlife enhancement measures proposed and approved under § 780.16 or § 784.16 of this chapter may be considered in making this determination. (vi) The appropriate state environmental agency has approved the plan. (10)(i) The owner of the surface of the lands within the proposed permit area has knowingly requested, in writing, as part of the application, that a variance be granted. (ii) The request must be made separately from any surface owner consent given for the operations under § 778.15 of this chapter and it must show an understanding that the variance could not be granted without the surface owner’s request. (iii) The surface owner has not and will not receive any monetary compensation, item of value, or other consideration in exchange for requesting the variance. (11) The proposed deviations from the premining surface configuration are necessary and appropriate to achieve the approved postmining land use. (12) The revegetation plan proposed under §§ 780.12(g) or 784.12(g) of this chapter requires the use of native tree and understory species to revegetate all portions of the permit area that are forested at the time of application or that would revert to forest under conditions of natural succession.

(a) The regulatory authority must determine the amount of the bond required for each area to be bonded, based upon, but not limited to— (1) The requirements of the permit, including the reclamation plan. (2) The probable difficulty of reclamation, giving consideration to the topography, geology, hydrology, and revegetation potential of the permit area and the biological condition of perennial and intermittent streams within the permit and adjacent areas. (3) The estimated reclamation costs submitted by the permit applicant. (b)(1) The amount of the bond must be sufficient to assure the completion of the reclamation plan if the work has to be performed by a third party under contract with the regulatory authority in the event of forfeiture.

The permittee may elect to either post a separate bond for this amount or incorporate that amount into the bond posted for the entire permit or increment. (c) When the permit includes a variance from approximate original contour restoration requirements under § 785.16 of this chapter, the amount of the bond must be sufficient to restore the disturbed area to the approximate original contour if the approved postmining land use is not implemented by the end of the applicable revegetation responsibility period under § 816.115 or § 817.115 of this chapter. (d) The amount of financial assurance required for treatment of long-term discharges must be determined in accordance with § 800.18 of this part.

(i) The regulatory authority may specify periodic times or set a schedule for reevaluating and adjusting the bond amount to fulfill this requirement. (ii) The permittee may request at any time that the regulatory authority reduce the amount of the performance bond based upon submission of evidence that the permittee’s method of operation or other circumstances will reduce the estimated unit costs for the regulatory authority to reclaim the bonded area. (iii) The regulatory authority may not use the provisions of this section to reduce the amount of the performance bond to reflect changes in the cost of reclamation resulting from completion of activities required under the reclamation plan. Bond reduction for completed reclamation activities must comply with the bond release requirements and procedures of §§ 800.40 through 800.44 of this part. (b) The regulatory authority must— (1) Notify the permittee, the surety, and any person with a property interest in collateral who has requested notification under § 800.21(f) of this part of any proposed adjustment to the bond amount; and (2) Provide the permittee an opportunity for an informal conference on the adjustment.

(B) Suckers on shrubby vegetation can be counted as volunteer plants when it is evident the shrub community is vigorous and expanding. (iv) The requirements of paragraphs (f)(2)(i) and (ii) of this section will be deemed met when records of woody vegetation planted show that— (A) No woody plants were planted during the last two growing seasons of the responsibility period; and, (B) If any replanting of woody plants took place earlier during the responsibility period, the total number planted during the last 60 percent of that period is less than 20 percent of the total number of woody plants required to meet the stocking standard. (3) Vegetative ground cover on areas planted with trees or shrubs must be of a nature that allows for natural establishment and succession of native plants, including trees and shrubs. (g) Special provision for areas that are developed within the revegetation responsibility period. Portions of the permit area that are developed for industrial, commercial, or residential use within the revegetation responsibility period need not meet production or stocking standards. For those areas, the vegetative ground cover must not be less than that required to control erosion. (h) Special provision for previously mined areas. Previously mined areas need only meet a vegetative ground cover standard, unless the regulatory authority specifies otherwise. At a minimum, the cover on the revegetated previously mined area must not be less than the ground cover existing before redisturbance and must be adequate to control erosion. (i) Special provision for prime farmland.

Stream Protection Rule

AGENCY: Office of Surface Mining Reclamation and Enforcement, Interior.

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: We, the Office of Surface Mining Reclamation and Enforcement 
(OSMRE or OSM), are proposing to revise our regulations, based on, 
among other things, advances in science, to improve the balance between 
environmental protection and the Nation's need for coal as a source of 
energy. This proposed rule would better protect streams, fish, 
wildlife, and related environmental values from the adverse impacts of 
surface coal mining operations and provide mine operators with a 
regulatory framework to avoid water pollution and the long-term costs 
associated with water treatment. We propose to revise our regulations 
to clearly define ``material damage to the hydrologic balance outside 
the permit area'' and require that each permit specify the point at 
which adverse mining-related impacts on groundwater and surface water 
would reach that level of damage; collect adequate premining data about 
the site of the proposed mining operation and adjacent areas to 
establish an adequate baseline for evaluation of the impacts of mining 
and the effectiveness of reclamation; adjust monitoring requirements to 
enable timely detection and correction of any adverse trends in the 
quality or quantity of surface water and groundwater or the biological 
condition of streams; ensure protection or restoration of perennial and 
intermittent streams and related resources; ensure that permittees and 
regulatory authorities make use of advances in science and technology; 
ensure that land disturbed by mining operations is restored to a 
condition capable of supporting the uses that it was capable of 
supporting before mining; and update and codify the requirements and 
procedures for protection of threatened or endangered species and 
designated critical habitat. The proposed changes would apply to both 
surface mines and the surface effects of underground mines. The 
majority of the proposed revisions update our regulations to 
incorporate or reflect the best available science and experience gained 
over the last 30 years. Approximately thirty percent of the proposed 
rule consists of editorial revisions and organizational changes 
intended to improve consistency, clarity, accuracy, and ease of use.

I. Executive Summary

    Significant advances in scientific knowledge and mining and 
reclamation techniques have occurred in the more than 30 years that 
have elapsed since the enactment of the Surface Mining Control and 
Reclamation Act of 1977 (SMCRA or the Act) \1\ and the adoption of 
federal regulations implementing that law. The proposed rule seeks to 
acknowledge the advancements in science, technology, policy, and the 
law that impact coal communities and natural resources, based on our 
experience and engagement with state regulatory authorities, industry, 
non-governmental organizations, academia, citizens, and other 
stakeholders.
---------------------------------------------------------------------------

    \1\ 30 U.S.C. 1201 et seq.
---------------------------------------------------------------------------

    The primary purpose of this proposed rule is to reinforce the need 
to minimize the adverse impacts \2\ of surface coal mining operations 
on surface water, groundwater, fish, wildlife, and related 
environmental values, with particular emphasis on protecting or 
restoring streams and aquatic ecosystems. The proposed rule, if adopted 
as final, also will enhance public health by reducing exposure to 
contaminants from coal mining in drinking water. The proposed rule has 
the following seven major elements:
---------------------------------------------------------------------------

    \2\ Impacts include loss of headwater streams, long-term 
degradation of water quality in streams downstream of a mine, 
displacement of native species, fragmentation of large blocks of 
mature hardwood forests, compaction and improper construction of 
postmining soils that inhibit the reestablishment of native plant 
communities and adverse impacts on watershed hydrology where coal 
mining occurs.
---------------------------------------------------------------------------

     First, the proposed rule defines the term ``material 
damage to the hydrologic balance outside the permit area'' and requires 
that each permit establish the point at which adverse mining-related 
impacts on groundwater and surface water reach an unacceptable level; 
i.e., the point at which adverse impacts from mining would cause 
material damage to the hydrologic balance outside the permit area.
     Second, the proposed rule sets forth how to collect 
adequate premining data about the site of the proposed mining operation 
and adjacent areas to establish a comprehensive baseline that will

[[Page 44439]]

facilitate evaluation of the effects of mining operations.
     Third, the proposed rule outlines how to conduct 
effective, comprehensive monitoring of groundwater and surface water 
during and after both mining and reclamation and during the 
revegetation responsibility period to provide real-time information 
documenting mining-related changes in water quality and quantity. 
Similarly, the proposed rule addresses the need to require monitoring 
of the biological condition of streams during and after mining and 
reclamation to evaluate changes in aquatic life. Proper monitoring 
would enable timely detection of any adverse trends and allow timely 
implementation of any necessary corrective measures.
     Fourth, the proposed rule promotes the protection or 
restoration of perennial and intermittent streams and related 
resources, especially the headwater streams that are critical to 
maintaining the ecological health and productivity of downstream 
waters.
     Fifth, the proposed rule is intended to ensure that 
permittees and regulatory authorities make use of advances in 
information, technology, science, and methodologies related to surface 
and groundwater hydrology, surface-runoff management, stream 
restoration, soils, and revegetation, all of which relate directly or 
indirectly to protection of water resources.
     Sixth, the proposed rule is intended to ensure that land 
disturbed by surface coal mining operations is restored to a condition 
capable of supporting the uses that it was capable of supporting before 
mining. Soil characteristics and the degree and type of revegetation 
have a significant impact on surface-water runoff quantity and quality 
as well as on aquatic life and the terrestrial ecosystems dependent 
upon perennial and intermittent streams. The proposed rule also would 
require revegetation of reclaimed minesites with native species unless 
and until a conflicting postmining land use, such as intensive 
agriculture, is implemented.
     Seventh, the proposed rule would update and codify 
requirements and procedures to protect threatened and endangered 
species and designated critical habitat under the Endangered Species 
Act of 1973.\3\ It also would better explain how the fish and wildlife 
protection and enhancement provisions of SMCRA should be implemented.
---------------------------------------------------------------------------

    \3\ 16 U.S.C. 1531 et seq.
---------------------------------------------------------------------------

    This proposed rule would more completely implement SMCRA's 
permitting requirements and performance standards, provide regulatory 
clarity to operators and stakeholders while better achieving the 
purposes of SMCRA as set forth in section 102 of the Act.\4\ In 
particular, the proposed rule would more completely realize the 
purposes in paragraphs (a), (c), (d), and (f) of that section, which 
include establishing a nationwide program to protect society and the 
environment from the adverse effects of surface coal mining operations 
and assuring that surface coal mining operations are conducted in an 
environmentally protective manner and are not conducted where 
reclamation is not feasible. Furthermore, the proposed rule is intended 
to address recent court decisions, mitigate legal challenges, and 
strike the appropriate balance between environmental protection, 
agricultural productivity and the Nation's need for coal as an 
essential source of energy, while providing greater regulatory 
certainty to the mining industry.
---------------------------------------------------------------------------

    \4\ 30 U.S.C. 1202.
---------------------------------------------------------------------------

    Apart from the procedural determinations in Part XIII, this 
document does not discuss the benefits and costs of the proposed rule 
in detail. Please refer to the draft regulatory impact analysis for an 
in-depth analysis of projected benefits and costs of the proposed rule 
and other alternatives under consideration.

II. Why are we proposing to revise our regulations?

    Our primary purpose in proposing this rule is to strike a better 
balance between ``protection of the environment and agricultural 
productivity and the Nation's needs for coal as an essential source of 
energy.'' \5\ Specifically, the proposed rule is designed to minimize 
the adverse impacts of surface coal mining operations on surface water, 
groundwater, and site productivity, with particular emphasis on 
protecting or restoring streams, aquatic ecosystems, riparian habitats 
and corridors, native vegetation, and the ability of mined land to 
support the uses that it was capable of supporting before mining. Our 
proposed changes reflect our experience during the more than three 
decades since adoption of the existing regulations, as well as advances 
in scientific knowledge and mining and reclamation techniques during 
that time. The proposed rule would more completely implement sections 
515(b)(24) and 516(b)(11) of SMCRA, which provide that, to the extent 
possible using the best technology currently available, surface coal 
mining and reclamation operations must be conducted to minimize 
disturbances and adverse impacts on fish, wildlife, and related 
environmental values and to achieve enhancement of those resources 
where practicable.\6\ It also would update our regulations concerning 
compliance with the Endangered Species Act of 1973.\7\ In addition, we 
propose to revise and reorganize our regulations for clarity, to make 
them more user-friendly, to remove obsolete and redundant provisions, 
and to implement plain language principles.

    \7\ 16 U.S.C. 1531 et seq.
---------------------------------------------------------------------------

    Coal mining operations continue to have adverse impacts on streams, 
fish, and wildlife despite the enactment of SMCRA and the adoption of 
federal regulations implementing that law more than 30 years ago. Those 
impacts include loss of headwater streams, long-term degradation of 
water quality in streams downstream of a mine, displacement of 
pollution-sensitive species of fish and insects by pollution-tolerant 
species, fragmentation of large blocks of mature hardwood forests, 
replacement of native species by highly competitive non-native species 
that inhibit reestablishment of native plant communities, and 
compaction and improper construction of postmining soils that result in 
a reduction of site productivity and adverse impacts on watershed 
hydrology.

Impacts on Aquatic Ecology

    Headwater streams consist of first-order through third-order 
streams \8\ under the Strahler stream-order system, which is the 
generally-accepted geographical classification system for ranking 
streams by size.\9\ Headwater streams are the small swales, creeks, and 
streams that connect to form larger streams and rivers. They trap 
floodwaters, recharge groundwater, remove pollution, provide fish and 
wildlife habitat, and sustain the health of downstream rivers, lakes, 
and bays. These streams support diverse biological communities of 
aquatic invertebrates, such as insects, and

[[Page 44440]]

vertebrates, including fish and salamanders, that are often distinct 
from the species found further downstream. Headwater streams function 
as sources of sediment, water, nutrients, and organic matter for 
downstream systems. Riparian vegetation provides organic matter to 
headwater streams in the form of dropped leaves and other plant parts. 
This organic matter fuels the aquatic food web.\10\ According to the 
U.S. Environmental Protection Agency (EPA), headwater streams that flow 
only seasonally or in response to precipitation events; i.e., 
intermittent and ephemeral streams, comprise approximately 53 percent 
of the total stream miles in the continental United States.\11\
---------------------------------------------------------------------------

    \8\ The U.S. Geological Survey sometimes characterizes only 
first-order and second-order streams as headwater streams. See, 
e.g., Argue, D. M., Pope, J. P., and Dieffenbach, Fred. 2012.

    \9\ See https://geography.about.com/od/physicalgeography/a/streamorder.htm (last accessed January 29, 2015). A first-order 
stream has no tributaries. When two first-order streams join, they 
form a second-order stream. When two second-order streams join, they 
form a third-order stream.

---------------------------------------------------------------------------

    Headwater streams are the streams most likely to be directly 
disturbed or impacted by coal mining activities. The EPA estimates that 
SMCRA permits in existence between 1992 and 2002 authorized the 
destruction of 1,208 miles of headwater streams.\12\ This total 
included approximately 2 percent of the total stream miles and 4 
percent of the first-order and second-order stream miles in the central 
Appalachian coalfields.\13\

023F, p. 16.
    \13\ Id. However, the fact that the mining plan in the permit 
authorized destruction of a stream segment does not necessarily mean 
that the destruction occurred. In some cases, the permittee may have 
decided not proceed with mining or to alter mining plans subsequent 
to permit issuance. An unknown amount of the habitat destruction was 
offset through the section 404 permitting process of the U.S. Army 
Corps of Engineers, which requires mitigation of loss or degradation 
of waters of the United States.
---------------------------------------------------------------------------

    Our proposed rule would address loss of stream miles in two ways. 
First, we propose to amend the standards governing excess spoil and 
coal mine waste to minimize both the generation of excess spoil and the 
placement of excess spoil and coal mine waste in perennial or 
intermittent streams. Second, we propose to adopt standards that would 
minimize mining through perennial and intermittent streams. When mining 
through a perennial or an intermittent stream does occur, our revised 
standards would require that the permittee restore both the 
hydrological form and the ecological function of the mined-through 
stream segment.
    Midwestern studies of reconstructed stream segments demonstrate 
that restoration of hydrological form and ecological function after 
mining through a stream is technologically feasible and attainable. In 
Illinois, case studies documented that streams flowing through channels 
reconstructed after mining can approach the regional biological 
diversity found in streams in unmined watersheds in that region.\14\ 
Another Illinois study focused on 25 miles of low-gradient perennial 
streams with moderately disturbed premining watersheds. Those stream 
segments were relocated in the 1980s to facilitate mining and then were 
restored in their approximate premining location, although two of the 
three streams were routed through permanent pit impoundments for part 
of their length. In general, the study found that the premining 
hydrological form and ecological function of the streams have been 
successfully restored, based on a comparison with relatively 
undisturbed segments of those streams that are upstream of the mining 
operations.\15\ The exception is fish abundance and diversity, which is 
substantially lower, perhaps, the authors suggest, because of the lack 
of mature riparian timber and instream woody debris.\16\ In addition, 
monitoring of habitat, water chemistry, and biological parameters of a 
low-gradient stream in Indiana that flows through a channel 
reconstructed after mining has demonstrated rapid recovery of the 
stream's ecological function.\17\

    The general consensus is that reconstruction and restoration of 
high-gradient streams after mining is more challenging. However, a 2012 
EPA publication notes that ``restoration of high-gradient, very small 
intermittent and ephemeral channels as part of stream mitigation 
projects is common in coalmining regions.'' \18\ This statement appears 
in the context of a discussion of improving existing degraded stream 
channels as mitigation for the adverse impacts of coal mining 
elsewhere, but the principles set forth in the publication also should 
apply to functional restoration of stream channels newly constructed or 
reconstructed as part of surface coal mining and reclamation 
operations. Appendix B of the publication describes a scenario in which 
high-gradient stream channels devoid of aquatic life on an abandoned 
minesite in West Virginia may be restored to biological health in an 
estimated 10 years.\19\

---------------------------------------------------------------------------

    Most adverse impacts of surface coal mining operations on water 
quality occur as a result of the excavation and fracturing of the rock 
layers above the coal seam. The mining process converts mostly solid 
rock, which has few pore spaces and thus offers little opportunity for 
chemical reaction with air and water, into highly fragmented mine 
spoil, which contains a vastly greater number and volume of pore spaces 
and thus offers much greater opportunity for chemical reaction with air 
and water. Surface water and groundwater infiltrate the pore spaces in 
mine spoil placed in the backfilled area of a mine or in an excess 
spoil fill and react with air and the surfaces of the rock fragments to 
produce drainage with high ionic concentrations. Specifically, water 
percolating through an excess spoil fill or the backfilled area of a 
mine typically contains substantially higher concentrations of sulfate, 
bicarbonate, calcium, and magnesium ions, as well as some trace metals, 
compared to the concentrations of those ions and metals in groundwater 
discharges and surface runoff from areas undisturbed by mining.\20\

    When sulfate is the dominant anion in those discharges, the result 
can be acid mine drainage, which mobilizes metals such as iron, 
manganese, aluminum, and zinc that are directly toxic to fish at high 
levels.\21\ But high concentrations of sulfate ions do not necessarily 
result in acid mine drainage because groundwater discharges and surface 
runoff from backfilled areas and excess spoil fills often also contain 
elevated concentrations of alkaline ions (especially calcium, 
magnesium, and carbonate ions), which neutralize the acidic sulfate 
ions, thus preventing the formation of acid mine drainage.\22\

    However, alkaline ions also can have negative impacts on water 
quality and aquatic life. Elevated concentrations of alkaline ions in 
mine drainage may result in significant increases in the pH and 
electrical conductivity of streams that receive discharges from mined 
areas.\23\ Elevated concentrations of both these ions and sulfate ions 
are highly correlated with elevated electrical conductivity in streams, 
which is highly correlated with the loss or absence of pollution-
sensitive species of aquatic insects and fish even when in-stream 
habitat downstream of the mining activity is otherwise intact.\24\ The 
adverse impacts may extend far downstream. One study found that adverse 
impacts from both surface and underground mines on water quality in 
Appalachian streams extended an average of 6.2 miles downstream from 
the mine.\25\

    The EPA has established an aquatic life benchmark of 300 
microsiemens per centimeter ([mu]S/cm) for electrical conductivity, 
based on a scientific determination that maintaining conductivity at or 
below this level should prevent the extirpation of 95 percent of 
invertebrate genera, such as mayflies, dragonflies, damselflies, and 
aquatic beetles, in central Appalachian streams.\26\ In other words, 
mining activities that cause an increase in the electrical conductivity 
of a stream to no more than 300 [mu]S/cm would be expected to result in 
the extirpation of no more than 5 percent of the invertebrate genera 
present in the stream before mining. A recent study suggests that a 
similar benchmark for fish would be somewhat higher because adverse 
impacts on the populations and diversity of fish species begin to 
appear at conductivity readings between 600 and 1,000 [mu]S/cm.\27\

Tennessee, Pennsylvania, Virginia, Alabama, and Maryland in 
Ecoregions 68, 69, and 70 because the salt matrix and background 
(calcium and magnesium cations and sulfate and bicarbonate anions at 
circum-neutral pH) is expected to be similar throughout those 
ecoregions. EPA further states that this benchmark also may be 
appropriate for other nearby regions, but that it may not apply when 
the relative concentrations of dissolved ions are different.

    Elevated electrical conductivity in streams can persist for many 
years after the completion of mining and land reclamation.\28\ This 
water quality characteristic can prevent or restrict recolonization by 
the species of fish \29\ and insects \30\ that inhabited the affected 
stream segment before mining began in the watershed. Studies in 
Appalachia of existing minesites have not found any ecologically 
significant improvement in electrical conductivity with either time or 
the extent of reforestation of the minesite.\31\ However, a recent 
study of test plots on a surface mine in Kentucky found that the 
quality of water emanating from plots that used the Forestry 
Reclamation Approach \32\ to soil reconstruction improved dramatically 
within 3 to 9 years after spoil placement, with electrical conductivity 
apparently stabilizing at levels 50 percent below those recorded during 
the first 3 years.\33\ Our proposed rule would address the conductivity 
issue by requiring that backfilling techniques consider impacts on 
electrical conductivity, by requiring that excess spoil fills be 
constructed in compacted lifts, and by incorporating elements of the 
Forestry Reclamation Approach into our soil reconstruction and 
revegetation rules.

Selenium Impacts

    In locations with geological formations that contain selenium, 
mining has sometimes resulted in elevated levels of selenium in streams 
downgradient of the minesite. Mining exposes elemental selenium to air, 
thus facilitating oxidation to selenite and selenate, which are soluble 
in water. Selenium bioaccumulates \34\ in fish tissues, causing 
reproductive problems, physical deformities, and, in extreme cases, 
mortality in fish in the affected streams.\35\ Selenium is beneficial 
to animals, including humans, when ingested in small amounts, but toxic 
when ingested in amounts ranging from 0.1 to 10 mg/kg of food.\36\ 
Humans have a dietary requirement estimated to be 0.04 to 0.10 mg/kg of 
food, but ingestion of selenium in amounts as low as 0.07 mg per day 
has been shown to have deleterious effects similar to arsenic 
poisoning.\37\ Thus, selenium concentrations in streams may be a human 
health concern when the stream serves as a drinking water supply or

[[Page 44442]]

when fish in the stream are used for human consumption.
---------------------------------------------------------------------------

    \34\ Bioaccumulation means an increase in the concentration of a 
chemical in a biological organism over time, compared to the 
chemical's concentration in the environment. Compounds accumulate in 
living things any time they are taken up and stored faster than they 
are broken down (metabolized) or excreted. See extoxnet.orst.edu/tibs/bioaccum.htm (last accessed January 6, 2015).
    \35\ Hitt and Chambers, op. cit., suggest that an aquatic life 
benchmark for total dissolved selenium concentrations using the 
criteria that EPA relied upon to establish a benchmark for 
electrical conductivity would be between four and seven micrograms 
per liter, at least for fish.

for Water'' (1976), p. 200.

---------------------------------------------------------------------------

    The proposed rule would address the environmental and human health 
concerns related to selenium by requiring collection of baseline 
hydrologic and geologic information on this element. If selenium is 
present in any of the overburden to be removed as part of the mining 
process, the proposed rule would require that the permit include limits 
on selenium discharges to prevent material damage to the hydrologic 
balance outside the permit area. The hydrologic reclamation plan and 
toxic materials handling plan must address selenium and the surface 
water and groundwater monitoring plans must include selenium.

Impacts on Stream Flow Regime and Flooding

    In addition to the water quality impacts discussed above, mining 
may affect the flow regime of streams by removing springs and otherwise 
causing changes in base flow, water temperature, seasonal variations in 
flow, and fluctuations in flow in response to storm events. Reclaimed 
minesites generally exhibit both reduced evapotranspiration (as a 
result of forest loss due to mining) and reduced infiltration of 
rainfall (as a result of soil compaction during reclamation), compared 
to unmined areas. A 2009 study of flood response in Virginia watersheds 
found that flood magnitude increased with the amount of surface-mined 
land within the watershed. In contrast, logging operations that removed 
most forest cover in similar Virginia watersheds increased overall 
water yield within the watershed without increasing flood volume, a 
difference that the authors of the study attributed to the soil 
compaction associated with typical surface mine reclamation. Another 
study in Maryland found that the volume of surface runoff as a result 
of a storm in a watershed influenced by surface mining was 
significantly higher than the volume of runoff from an undisturbed 
forested watershed as a result of the same-size storm. The authors 
attributed this difference to soil compaction on the mined land, which 
reduced infiltration rates to less than 1 cm/hr, compared to 30 cm/hr 
in the undisturbed watershed. Increased surface runoff in response to 
storms increases the potential for flood damage and may adversely 
impact the hydrological function of the stream by causing stream 
channelization.\38\ Our proposed rule would address this issue by 
minimizing soil compaction and maximizing reforestation.

Impacts on Topography and Microclimates

    Mining impacts on the terrestrial environment include a loss of 
topographic complexity; i.e., regraded minesites generally are flatter 
and more uniform in terms of surface elevation and configuration when 
compared with the premining topography. U.S. Geological Survey studies 
of central Appalachia found that surface coal mining reduced ridgetop 
elevations by an average of 112 feet, raised valley floor elevations by 
an average of 174 feet, reduced slope steepness by 9.5-11 percent, and 
changed slope aspect \39\ by 38-41 degrees.\40\ Changes are less 
dramatic in areas with flatter topography, but the same principle of 
greater uniformity and less topographic diversity after mining and 
regrading still applies. Regraded minesites usually lack the small 
drainageways and variations in slope and other topographical features 
found prior to mining. Therefore, they also lack the microclimates and 
associated ecosystems found prior to mining. Landsat data from 2007-
2009 for the area containing a large mountaintop removal mining 
operation in West Virginia indicate that surface temperatures of areas 
disturbed by mining were warmer and more variable in all seasons except 
winter.\41\ Surface temperatures influence the type of vegetation that 
can survive on mined land and the extent and rate at which the 
premining plant community and associated fauna can recolonize the site.
---------------------------------------------------------------------------

a significant effect on the soils and microclimate of the slope and 
hence on the plant and animal life found there, as well as the 
site's productivity.

---------------------------------------------------------------------------

Impacts on Soils, Vegetation, and Terrestrial Wildlife

    Other terrestrial impacts include forest fragmentation (loss of 
large blocks of contiguous mature interior forest and increases in 
forest edge and grassland habitat), loss of native forests, changes in 
species composition and biodiversity of both plants and animals, and 
loss or severe compaction of soil horizons and organic matter. At least 
temporarily, mining of previously forested areas adversely impacts 
species that prefer or require interior forest (for example, the 
cerulean warbler, the ovenbird, and the scarlet tanager) and favors 
species that prefer or require edge habitat (for example, the cardinal, 
the brown-headed cowbird, and many species of sparrows).
    Furthermore, conventional reclamation techniques typically result 
in heavily compacted soils that offer a hostile environment for native 
plant species and soil microorganisms, which means that minesites 
reclaimed by those techniques often are either planted with or 
colonized by nonnative species and remain in a state of arrested 
ecological succession. Both soil compaction and competitive herbaceous 
ground covers inhibit the establishment of native forests similar to 
those that occupied the area prior to mining. Soil compaction also 
reduces the site indices for tree growth, which means that the 
reclaimed minesite is not capable of supporting a forest with a 
productivity equal to that of the forest that either existed or could 
have existed prior to mining.
    Our proposed rule would address terrestrial impacts in a variety of 
ways, including a requirement for restoration of the premining drainage 
pattern to the extent possible and incorporation of elements of the 
Forestry Reclamation Approach. Use of that approach would minimize soil 
compaction and maximize reforestation and restoration of site 
productivity. Our proposed rule emphasizes revegetation with native 
species, restoration of natural plant communities whenever there is no 
conflict with implemented postmining land uses, and the protection or 
establishment of riparian corridors along streams to promote 
protection, restoration, and enhancement of fish, wildlife, and related 
environmental values. It also would modify the standards for approval 
of exceptions to the approximate original contour restoration 
requirement by limiting exceptions to those necessary to implement the 
postmining land use within the revegetation responsibility period.

Draft Environmental Impact Statement (EIS)

    The draft EIS for this proposed rule contains an expanded 
discussion of the impacts of mining on the environment. Almost all the 
literature surveys and studies reviewed for this rulemaking process 
have been published since the adoption in 1983 of our principal 
regulations concerning protection of the hydrologic balance \42\ and 
protection of fish, wildlife, and related environmental

values,\43\ which underscores the need to update our regulations to 
reflect new scientific understanding of impacts associated with coal 
mining.

Relationship to 2009 MOU

    This proposed rule helps fulfill our responsibilities under a 
memorandum of understanding (MOU) that the Secretary of the Department 
of the Interior, the Administrator of the EPA, and the Acting Assistant 
Secretary of the Army (Civil Works) entered into on June 11, 2009. This 
MOU implemented an interagency action plan designed to significantly 
reduce the harmful environmental consequences of surface coal mining 
operations in six Appalachian states and ensure that future mining is 
conducted consistent with federal law. Specifically, Part III.A. of the 
MOU provides that we will review our ``existing regulatory authorities 
and procedures to determine whether regulatory modifications should be 
proposed to better protect the environment and public health from the 
impacts of Appalachian surface coal mining.'' It also provides that, at 
a minimum, we will consider revisions to the stream buffer zone rule 
published December 12, 2008,\44\ and our existing regulatory 
requirements concerning approximate original contour. Ultimately, we 
determined that development of a comprehensive, nationally applicable 
stream protection rule would be the most appropriate and effective 
method of achieving the purposes and requirements of SMCRA, as well as 
meeting the goals set forth in the MOU.\45\
---------------------------------------------------------------------------

    \44\ The U.S. District Court for the District of Columbia 
vacated the 2008 stream buffer zone rule on February 20, 2014, in 
National Parks Conservation Ass'n v. Jewell, 2014 U.S. Dist. LEXIS 
152383 (D.D.C. Feb. 20, 2014). See also 79 FR 76227-76233 (Dec. 22, 
2014).
    \45\ In keeping with our commitment in the MOU, we considered 
making revisions to our approximate original contour regulations. 
Ultimately, we decided not to propose any major changes to our 
permitting requirements and performance standards concerning 
approximate original contour restoration at this time because of 
cost concerns and perceived difficulty of implementation. However, 
we are proposing revisions to our regulations governing exceptions 
to the requirement to restore the approximate original contour.
---------------------------------------------------------------------------

III. What needs does this proposed rule address?

    All versions of the stream buffer zone rule that we have adopted 
over the years, including the version now in effect, focused primarily 
on activities in or within 100 feet of the stream itself.\46\ Yet, 
mining activities beyond the 100-foot stream buffer zone can adversely 
impact the quality and quantity of water in streams by disturbing 
aquifers, by altering the physical and chemical nature of recharge 
zones as well as surface-water runoff and infiltration rates and 
drainage patterns, and by modifying the topography and vegetative 
composition of the watershed. Thus, there are many components of our 
regulations that could be revised to improve implementation of SMCRA 
with regard to protection of streams in particular and the hydrologic 
balance in general. We have identified six specific areas in which we 
propose to revise our regulations to better protect streams and 
associated environmental values.
---------------------------------------------------------------------------

    \46\ The 2008 rule was somewhat broader in that it also included 
provisions intended to minimize the creation of excess spoil and to 
limit the footprint of excess spoil fills.
---------------------------------------------------------------------------

    First, while ephemeral streams derive their flow from surface 
runoff from precipitation events, perennial and intermittent streams 
derive their flow from both groundwater discharges and surface runoff 
from precipitation events. Therefore, there is a need to clearly define 
the point at which adverse mining-related impacts on both groundwater 
and surface water reach an unacceptable level; that is, the point at 
which adverse impacts from mining cause material damage to the 
hydrologic balance outside the permit area. Neither SMCRA nor the 
existing regulations define the term ``material damage to the 
hydrologic balance outside the permit area'' or establish criteria for 
determining what level of adverse impacts would constitute material 
damage. In particular, there is no requirement that the SMCRA 
regulatory authority establish a specific standard for conductivity or 
selenium, both of which can have deleterious effects on aquatic life at 
elevated levels.
    Second, there is a need to collect adequate premining data about 
the site of the proposed mining operation and adjacent areas to 
establish a comprehensive baseline that will facilitate evaluation of 
the effects of mining. The existing rules require data only for a 
limited number of water-quality parameters rather than the full suite 
needed to establish a complete baseline against which the impacts of 
mining can be compared. The existing rules also contain no requirement 
for determining the biological condition of streams within the proposed 
permit and adjacent areas, so there is no assurance that the permit 
application will include baseline data on aquatic life.
    Third, there is a need for effective, comprehensive monitoring of 
groundwater and surface water during and after both mining and 
reclamation and during the revegetation responsibility period to 
provide real-time information documenting mining-related changes in the 
values of the parameters being monitored. Similarly, there is a need to 
require monitoring of the biological condition of streams during and 
after mining and reclamation to evaluate changes in aquatic life. 
Proper monitoring will enable timely detection of any adverse trends 
and timely implementation of any necessary corrective measures. The 
existing rules require monitoring of only water quantity and a limited 
number of water-quality parameters, not all parameters necessary to 
evaluate the impact of mining and reclamation. The existing rules do 
not ensure that the number and location of monitoring points will be 
adequate to determine the impact of mining and reclamation. They also 
allow discontinuance or reduction of water monitoring too early to 
ascertain the impacts of mining and reclamation on water quality with a 
reasonable degree of confidence, especially for groundwater.
    Fourth, there is a need to ensure protection or restoration of 
streams and related resources, including the headwater streams that are 
important to maintaining the ecological health and productivity of 
downstream waters. The existing rules have not always been applied in a 
manner sufficient to ensure protection or restoration of streams, 
especially with respect to the ecological function of streams. 
Maintenance, restoration, or establishment of riparian corridors or 
buffers, comprised of native species, for streams is a critical element 
of stream protection. In forested areas, riparian buffers for streams 
moderate the temperature of water in the stream, provide food (in the 
form of fallen leaves and other plant parts) for the aquatic food web, 
roots that stabilize stream banks, reduce surface runoff, and filter 
sediment and nutrients in surface runoff.
    Fifth, there is a need to ensure that permittees and regulatory 
authorities make use of advances in information, technology, science, 
and methodologies related to surface and groundwater hydrology, 
surface-runoff management, stream restoration, soils, and revegetation, 
all of which relate directly or indirectly to protection of water 
resources.
    Sixth, there is a need to ensure that land disturbed by surface 
coal mining operations is restored to a condition capable of supporting 
the uses that it was capable of supporting before any mining, including 
both those uses dependent upon stream protection or restoration and 
those uses that promote or support protection and restoration of

[[Page 44444]]

streams and related environmental values. Existing rules and permitting 
practices have focused primarily on the land's suitability for a single 
approved postmining land use and they have not always been applied in a 
manner that results in the construction of postmining soils that 
provide a growth medium suitable for restoration of premining site 
productivity. A corollary need is to ensure that reclaimed minesites 
are revegetated with native species unless and until a conflicting 
postmining land use, such as intensive agriculture, is implemented. 
Soil characteristics and the degree and type of revegetation have a 
major impact on surface-water runoff quantity and quality as well as on 
aquatic life and the terrestrial ecosystems dependent upon perennial 
and intermittent streams. Under the existing rules, sites with certain 
postmining land uses have been revegetated with non-native species even 
when the postmining land use is not implemented prior to final bond 
release and even on those portions of the site where non-native species 
are not necessary to achieve the postmining land use.
    The proposed rule would address these needs in the manner described 
in Part IX of this preamble. As mentioned in Part II of this preamble, 
we determined that improved protection of the hydrologic balance, 
especially streams, and related environmental values would benefit all 
regions of the country, not just Appalachia. In addition, one of the 
reasons SMCRA was enacted was to ensure a minimum level of 
environmental protection nationwide by establishing national surface 
coal mining and reclamation standards to prevent competition for coal 
markets from undermining the ability of states to maintain adequate 
regulatory programs for coal mining operations within their borders. 
See section 101(g) of SMCRA, 30 U.S.C. 1201(g). Thus, we concluded that 
a nationwide rule is required to clearly articulate a minimum standard 
for protection of the hydrologic balance, especially streams, and 
related environmental values that strikes an appropriate balance 
between environmental protection and the Nation's need for coal.

IV. What Clean Water Act programs protect streams?

    The goal of the Clean Water Act is to ``restore and maintain the 
chemical, physical, and biological integrity of the Nation's waters.'' 
\47\ To achieve that objective, section 301 of the Clean Water Act \48\ 
prohibits the discharge of pollutants from point sources into waters of 
the United States unless consistent with the requirements of the Act. 
Section 402 of the Clean Water Act \49\ governs the discharge of 
pollutants other than dredged or fill material, while section 404 \50\ 
governs the discharge of dredged or fill material into waters of the 
United States.

    \50\ 33 U.S.C. 1344.
---------------------------------------------------------------------------

Section 303 Water Quality Standards

    Section 303 of the Clean Water Act \51\ requires states to adopt 
water quality standards applicable to their intrastate and interstate 
waters. Water quality standards assist in maintaining the physical, 
chemical, and biological integrity of a water body by designating uses, 
setting water quality criteria to protect those uses, and establishing 
provisions to protect water quality from degradation. Water quality 
standards established by states \52\ are subject to EPA review. 40 CFR 
131.5; 33 U.S.C. 1313(c). EPA may object to state-adopted water quality 
standards and may require changes to the state-adopted water quality 
standards and, if the state does not respond to EPA's objections, EPA 
may promulgate federal standards. 33 U.S.C. 1313(c)(3)-(4); 40 CFR 
131.5, 131.21.
---------------------------------------------------------------------------

    \51\ 33 U.S.C. 1313.
    \52\ EPA may treat an eligible federally-recognized Indian tribe 
in the same manner as a state for implementing and managing certain 
environmental programs, including under the Clean Water Act.
---------------------------------------------------------------------------

    Water quality criteria may be expressed numerically and implemented 
in permits through specific numeric limitations on the concentration of 
a specific pollutant in the water (e.g., 0.1 milligrams of chromium per 
liter) or by more general narrative standards applicable to a wide set 
of pollutants. To assist states in adopting water quality standards 
that will meet with EPA's approval, Congress authorized EPA to develop 
and publish recommended criteria for water quality that accurately 
reflect ``the latest scientific knowledge.'' 33 U.S.C. 1314(a). Water 
quality standards are not self-implementing; they are implemented 
through permits, such as the section 402 permit or the section 404 
permit. 33 U.S.C. 1311(b)(1)(C); 40 CFR 122.44(d), 230.10(b).

Section 401 Water Quality Certification

    State water quality standards are incorporated into all federal 
Clean Water Act permits through section 401, which requires each 
applicant to submit a certification from the affected state that the 
discharge will be consistent with state water quality requirements. 33 
U.S.C. 1341(a)(1). Thus, section 401 provides states with a veto over 
federal permits that may allow exceedances of state water quality 
standards. It also empowers states to impose and enforce water quality 
standards that are more stringent than those required by federal law. 
33 U.S.C. 1370.

Section 402 National Pollutant Discharge Elimination System (NPDES)

    Section 402 of the Clean Water Act governs discharges of pollutants 
other than dredged or fill material into waters of the United States. 
Permits issued under the authority of section 402 are known as NPDES 
permits. They typically contain numerical limits called effluent 
limitations that restrict the amounts of specified pollutants that may 
be discharged. NPDES permits must contain technology-based effluent 
limits and any more stringent water quality-based effluent limits 
necessary to meet applicable state water quality standards. 33 U.S.C. 
1311(b)(1)(A) and (C), 33 U.S.C. 1342(a); 40 CFR 122.44(a)(1) and 
(d)(1). Water quality-based effluent limitations are required for all 
pollutants that the permitting authority determines ``are or may be 
discharged at a level [that] will cause, have the reasonable potential 
to cause, or contribute an excursion above any [applicable] water 
quality standard, including State narrative criteria for water 
quality.'' 40 CFR 122.44(d)(1)(i). The procedure for determining the 
need for water quality-based effluent limits is called a reasonable 
potential analysis, or ``RPA.''
    Section 402 permits are issued by EPA unless the state has an 
approved program whereby the state issues the permits, subject to EPA 
oversight. 33 U.S.C. 1342(b)(e); 551 U.S. 644, 650-651 (2007). The 
state must submit draft permits to EPA for review, and EPA may object 
to a proposed permit that is not consistent with the Clean Water Act 
and federal regulations. 33 U.S.C. 1342(d); 40 CFR 123.43 and 123.44. 
If the state does not adequately address EPA's objections, EPA may 
assume the authority to issue the permit. 33 U.S.C. 1342(d)(4). EPA's 
procedures for the review of state-issued permits are set forth in 
regulations at 40 CFR 123.44 and in memoranda of agreement with the 
states.

Section 404 Permits

    Section 404(a) of the Clean Water Act authorizes the Secretary of 
the Army, acting through the U.S. Army Corps of Engineers (ACE or the 
Corps), to ``issue

[[Page 44445]]

permits . . . for the discharge of dredged or fill material into the 
navigable waters at specified disposal sites.'' 33 U.S.C. 1344(a). By 
this authority, the ACE regulates discharges of dredged and fill 
material into waters of the United States in connection with surface 
coal mining and reclamation operations. The ACE's regulations governing 
section 404 permit procedures are set forth at 33 CFR part 325.
    Although the ACE is the permitting authority under section 404, EPA 
has an important role in the permitting process. Section 404(b) of the 
Clean Water Act requires that permitting decisions comply with 
guidelines developed by EPA in conjunction with the ACE. These 
guidelines, which are referred to as the ``404(b)(1) Guidelines,'' are 
codified in 40 CFR part 230. Among other things, the 404(b)(1) 
Guidelines prohibit the discharge of fill if it would cause or 
contribute to a violation of a water quality standard or cause or 
contribute to significant degradation of the waters of the United 
States. 40 CFR 230.10(b), (c)(1) through (c)(3). The 404(b)(1) 
Guidelines require the ACE to analyze more than 15 different factors 
that could be impacted by the proposed action, including substrate, 
suspended particulates, turbidity, water quality, water circulation, 
water level fluctuations, salinity gradients, threatened and endangered 
species, aquatic organisms in the food web, other wildlife special 
aquatic sites, water supplies, fisheries, recreation, aesthetics, and 
parks. 40 CFR 230(c) through (f). The 404(b)(1) Guidelines provide that 
the ACE must ensure that the proposed discharges would not cause or 
contribute to significant adverse effects on human health or welfare, 
aquatic life, or aquatic ecosystems. 40 CFR 230.10(c)(1) through 
(c)(3).
    Before the ACE may issue a section 404 permit, it must provide 
notice to the public, EPA, and other resource agencies, which may 
provide comments to the ACE for consideration. 33 CFR 325.3(d). In 
addition, the ACE and EPA have entered into a Memorandum of Agreement 
(MOA) as directed by section 404(q) of the Clean Water Act, 33 U.S.C. 
1344(q), that expressly recognizes that ``the EPA has an important role 
in the Department of the Army Regulatory Program under the Clean Water 
Act[.]'' The MOA provides that ``[p]ursuant to its authority under 
section 404(b)(1) of the Clean Water Act, the EPA may provide comments 
to the Corps identifying its views regarding compliance with the 
section 404(b)(1) Guidelines'' and ``[t]he Corps will fully consider 
EPA's comments when determining [compliance] with the National 
Environmental Policy Act, and other relevant statutes, regulations, and 
policies.'' Id.
    In addition, section 404(c) of the Clean Water Act provides EPA 
with the authority to prohibit, withdraw, deny, or restrict the 
specification of disposal sites that would otherwise be authorized by a 
section 404 permit. This provision is often referred to as EPA's permit 
veto authority.
    The ACE reviews individual permit applications under section 404(a) 
of the Clean Water Act on a case-by-case basis. 33 U.S.C. 1344(a). 
Individual permits may be issued or denied after a review involving, 
among other things, site-specific documentation and analysis, 
opportunity for public hearing, public interest review, and a formal 
determination that the permit is lawful and warranted. 33 CFR parts 
320, 323, and 325.
    Not every discharge is of such significance that an individual 
evaluation of the discharge's environmental effects is necessary. 
Instead, section 404(e) of the Clean Water Act authorizes the Secretary 
of the Army to issue general permits for categories of activities 
involving discharges of dredged or fill material that, as a group, have 
only minimal impacts on the waters of the United States. The ACE can 
issue these general permits (as well as individual permits) on a state, 
regional, or nationwide basis. The ACE refers to general permits issued 
on a nationwide basis as ``nationwide permits'' (NWP). NWPs must be 
reviewed reissued every 5 years to remain valid. The ACE last reissued 
the NWPs on February 21, 2012 (77 FR 10184).
    NWP 21, Surface Coal Mining Activities, provides authorization for 
the discharge of dredged or fill material into waters of the United 
States when those discharges are associated with surface coal mining 
activities. The permittee must submit a preconstruction notification to 
the ACE district engineer and receive written authorization prior to 
commencing the activity. The ACE review of preconstruction 
notifications under NWP 21 is focused on the individual and cumulative 
adverse effects to the aquatic environment and on determining 
appropriate mitigation should mitigation be necessary. The ACE review 
does not extend to upland areas or the mining operation as a whole.
    To qualify for NWP 21, an activity must meet all of the following 
criteria:
    (1) The activities are already authorized or are currently being 
processed by a SMCRA-approved state program or an integrated permit 
processing procedure by the Department of the Interior.
    (2) The discharge will not cause the loss of more than \1/2\ acre 
of non-tidal waters of the United States, including the loss of no more 
than 300 linear feet of streambed, unless, for intermittent and 
ephemeral streambeds, the ACE district engineer waives the 300-linear-
foot limit by making a written determination concluding that the 
discharge will result in minimal individual and cumulative adverse 
effects.
    (3) The discharge is not associated with the construction of valley 
fills which are fill structures associated with surface coal mining 
activities that are typically constructed within valleys associated 
with steep, mountainous terrain.
    Any surface mining activity that does not meet all three criteria 
must apply for an individual permit instead unless the activity 
qualifies for NWP 49 as discussed below.
    Two other NWPs may apply to coal mining activities under SMCRA.
    NWP 49, Coal Remining Activities, applies to discharges of dredged 
or fill material into non-tidal waters of the United States when those 
discharges are associated with the remining and reclamation of lands 
that were previously mined for coal. The activities must already be 
authorized by the SMCRA regulatory authority or be in process as part 
of an integrated permit processing procedure under SMCRA.
    The permittee may conduct new coal mining activities in conjunction 
with the remining activities when he or she clearly demonstrates to the 
ACE that the overall mining plan will result in a net increase in 
aquatic resource functions. The ACE will consider the SMCRA regulatory 
authority's decision regarding the amount of currently undisturbed 
adjacent lands needed to facilitate the remining and reclamation of the 
previously mined area. The total area disturbed by new mining must not 
exceed 40 percent of the total acreage covered by both the remined area 
and the additional area necessary to carry out the reclamation of the 
previously mined area. The permittee must submit a pre-construction 
notification and a document describing how the overall mining plan will 
result in a net increase in aquatic resource functions to the district 
engineer and receive written authorization prior to commencing the 
activity.

[[Page 44446]]

    NWP 50, Underground Coal Mining Activities, applies to discharges 
of dredged or fill material into non-tidal waters of the United States 
when those discharges are associated with the remining and reclamation 
of lands that were previously mined for coal. The activities must 
already be authorized by the SMCRA regulatory authority or be in 
process as part of an integrated permit processing procedure under 
SMCRA.
    The discharge must not cause the loss of greater than \1/2\ acre of 
non-tidal waters of the United States, including the loss of no more 
than 300 linear feet of stream bed, unless, for intermittent and 
ephemeral streambeds, the ACE district engineer waives the 300-linear-
foot limit by making a written determination concluding that the 
discharge will result in minimal adverse effects. This NWP does not 
authorize coal preparation and processing activities outside the 
minesite or discharges into nontidal wetlands adjacent to tidal waters. 
The permittee must submit a pre-construction notification to the ACE 
district engineer and receive written authorization prior to commencing 
the activity.

V. What provisions of SMCRA provide legal authority for the proposed 
rule?

    This proposed rule would more completely implement SMCRA's 
permitting requirements and performance standards and better achieve 
the purposes of SMCRA as set forth in section 102 of the Act.\53\ It is 
intended to balance all relevant purposes of the Act, which include 
ensuring that surface coal mining operations are conducted in a manner 
that protects the environment, establishing a nationwide program to 
protect society and the environment from the adverse effects of surface 
coal mining operations, and ensuring a coal supply adequate for our 
Nation's energy needs.
---------------------------------------------------------------------------

    Our proposed rule is intended to address the adverse impacts and 
needs discussed in Parts II and III of this preamble by adding 
specificity to and otherwise revising our existing regulations to more 
completely implement various provisions of SMCRA, including, but not 
limited to:
    Section 101(c),\54\ in which Congress finds that ``many surface 
coal mining operations result in disturbances of surface areas that 
burden and adversely affect commerce and the public welfare by * * * 
polluting the water, by destroying fish and wildlife habitats, by 
impairing natural beauty, * * * and by counteracting governmental

VI. What is the history of our regulation of coal mining in relation to 
buffer zones for streams?

    The U.S. House of Representatives first passed a bill (H.R. 6482) 
to regulate surface coal mining operations in 1972. Section 9(a) of 
that bill included a flat prohibition on mining within 100 feet of any 
``body of water, stream, pond, or lake to which the public enjoys use 
and access, or other private property.'' However, the bill never became 
law and the provision did not appear in either the House or Senate 
versions of the bills that ultimately became SMCRA. Therefore, nothing 
in SMCRA specifically establishes or requires a buffer zone for 
streams, although sections 515(b)(24) and 516(b)(11) of SMCRA \72\ 
require that mining operations minimize disturbances and adverse 
impacts on fish, wildlife, and related environmental values to the 
extent possible using the best technology currently available. We have 
consistently interpreted those and other provisions of SMCRA as meaning 
that protection of perennial and intermittent streams, with their 
intrinsic value to fish and wildlife, is an important element of the 
environmental protection regime that SMCRA established. Since the 
enactment of SMCRA, we have adopted four sets of regulations, which we 
discuss below, that included the concept of a buffer zone for streams.
---------------------------------------------------------------------------

    \72\ 30 U.S.C. 1265(b)(24) and 1266(b)(11).
---------------------------------------------------------------------------

The 1977 Stream Buffer Zone Rule

    In 1977, we published initial regulatory program regulations 
providing that no land within 100 feet of an intermittent or perennial 
stream could be disturbed by surface coal mining and reclamation 
operations unless the regulatory authority specifically authorizes 
those operations. See 30 CFR 715.17(d)(3) and 717.17(d), as published 
at 42 FR 62639, 62686, 62697 (Dec. 13, 1977). We stated that we adopted 
that rule as a means ``to protect stream channels from abnormal 
erosion'' from nearby upslope mining activities.\73\ However, that 
rule, which applies only to the now-limited subset of surface coal 
mining and reclamation operations subject to the initial regulatory 
program, does not specify the conditions under which the regulatory 
authority may authorize surface coal mining operations within the 
buffer zone.
---------------------------------------------------------------------------

    \73\ Id. at 62652.
---------------------------------------------------------------------------

The 1979 Stream Buffer Zone Rule

    In 1979, we published the original version of our permanent 
regulatory program regulations. Those regulations, as codified at 30 
CFR 816.57 and 817.57, provided that, with the exception of stream 
diversions, the surface of land within 100 feet of a perennial stream 
or a non-perennial stream with a biological community could not be 
disturbed by surface mining activities or surface operations and 
facilities associated with an underground mine unless the regulatory 
authority specifically authorized mining-related activities closer to 
or through the stream. Under the regulations, the regulatory authority 
could grant that authorization only after making a finding that the 
original stream channel would be restored and that, during and after 
the mining, the water quantity and quality in the section of the stream 
within 100 feet of the mining activities would not be adversely 
affected.
    Paragraph (c) of these rules provided that a biological community 
existed if, at any time, the stream contained an assemblage of two or 
more species of arthropods or molluscan animals that were adapted to 
flowing water for all or part of their life cycle, dependent upon a 
flowing water habitat, reproducing or could reasonably be expected to 
reproduce in the water body where they are found, and longer than two 
millimeters at some stage of the part of their life cycle spent in the 
flowing water habitat. See 44 FR 14902, 15175 (Mar. 13, 1979).
    The preamble to the 1979 rules explains that the purpose of the 
revised rules was to implement paragraphs (b)(10) and (b)(24) of 
section 515 of the Act.\74\ It states that ``[b]uffer zones are 
required to protect streams from the adverse effects of sedimentation 
and from gross disturbance of stream channels,'' but that ``if 
operations can be conducted within 100 feet of a stream in an 
environmentally acceptable manner, they may be approved.'' \75\ In 
addition, it states that ``[t]he 100-foot limit is based on typical 
distances that should be maintained to protect stream channels from 
sedimentation,'' but that, while the 100-foot standard provides a 
simple rule for enforcement purposes, ``site-specific variation should 
be made available when the regulatory authority has an objective basis 
for either increasing or decreasing the width of the buffer zone.''

The 1983 Stream Buffer Zone Rule

    In 1983, we revised 30 CFR 816.57 and 817.57 by deleting the 
requirement to restore the original stream channel. We also replaced 
the biological community criterion for determining which non-perennial 
streams are protected under the rule with a requirement for protection 
of all perennial and intermittent streams. We redefined an intermittent 
stream as a stream or reach of a stream that (a) drains a watershed of 
at least one square mile or (b) is below the local water table for at 
least some part of the year and obtains its flow from both surface 
runoff and groundwater discharge. Finally, we replaced the 1979 finding 
with a requirement that the regulatory authority find that the proposed 
mining activities would not cause or contribute to a violation of 
applicable state or federal water quality standards and would not 
adversely affect the quantity or quality of the water in the stream or 
the other environmental resources of the stream. See 48 FR 30312, 
30327-30328 (Jun. 30, 1983).
    In 1983, we also adopted revised performance standards for coal 
preparation plants not located within the permit area of a mine. At 
that time, we decided not to apply the stream buffer zone rule to those 
preparation plants. See 30 CFR 827.12 and the preamble to those rules 
at 48 FR 20399 (May 5, 1983).
    The preamble to the 1983 stream buffer zone rules reiterates the 
general rationale for adoption of a stream buffer zone rule that we 
specified in the preamble to the 1979 rules. In addition, it identifies 
the reason for replacing the biological community criterion with the 
intermittent stream threshold as a matter of improving the ease of 
administration and eliminating the possibility of applying the rule to 
ephemeral streams:

    The biological-community standard was confusing to apply since 
there are areas with ephemeral surface waters of little biological 
or hydrologic significance which, at some time of the year, contain 
a biological community as defined by previous Sec.  816.57(c). Thus, 
much confusion arose when operators attempted to apply the previous 
rule's standards to springs, seeps,

[[Page 44448]]

ponding areas, and ephemeral streams. While some small biological 
communities which contribute to the overall production of downstream 
ecosystems will be excluded from special buffer-zone protection 
under final Sec.  816.57(a), the purposes of Section 515(b)(24) of 
the Act will best be achieved by providing a buffer zone for those 
streams with more significant environmental-resource values.\77\
---------------------------------------------------------------------------

    \77\ 48 FR 30313 (Jun. 30 1983). Based upon additional 
scientific information developed over the last 30 years, we no 
longer concur with this characterization of the significance of 
ephemeral streams.

    Referring to those streams that would not be protected by 30 CFR 
816.57, i.e., ephemeral streams, the preamble further states that 
``[i]t is impossible to conduct surface mining without disturbing a 
number of minor natural streams, including some which contain biota.'' 
\78\ Referring to those streams that would be protected by 30 CFR 
816.57, i.e., perennial and intermittent streams, the preamble also 
states that ``surface coal mining operations will be permissible as 
long as environmental protection will be afforded to those streams with 
more significant environmental-resource value.'' \79\ The preamble 
further provides that the revised rules ``also recognize that 
intermittent and perennial streams generally have environmental-
resource values worthy of protection under Section 515(b)(24) of the 
Act.'' \80\ In addition, the preamble notes that ``[a]lthough final 
Sec.  816.57 is intended to protect significant biological values in 
streams, the primary objective of the rule is to provide protection for 
the hydrologic balance and related environmental values of perennial 
and intermittent streams''.\81\ It further states that ``[t]he 100-foot 
limit is used to protect streams from sedimentation and help preserve 
riparian vegetation and aquatic habitats.'' \82\

elsewhere in this preamble, implementation of the 1983 rule has not 
resulted in uniform or consistent achievement of this primary 
objective.
    \82\ Id. at 30314.
---------------------------------------------------------------------------

    We also stated that we removed the requirement to restore the 
original stream channel in deference to the stream-channel diversion 
requirements of 30 CFR 816.43 and 817.43 and to clarify that there does 
not have to be a stream diversion for mining to occur inside the buffer 
zone.\83\
---------------------------------------------------------------------------

    \83\ Id.
---------------------------------------------------------------------------

    Finally, the preamble states that we expanded the finding in 30 CFR 
816.57(a)(1) to include environmental resources of the stream other 
than water quantity and quality to clarify ``that regulatory 
authorities will be allowed to consider factors other than water 
quantity and quality in making buffer-zone determinations'' and ``to 
provide a more accurate reflection of the objectives of Sections 
515(b)(10) and 515(b)(24) of the Act.'' \84\ In fact, the language of 
the revised finding not only allowed regulatory authorities to consider 
environmental resources of the stream other than water quantity and 
quality, it required that they do so.
---------------------------------------------------------------------------

    \84\ Id. at 30316.
---------------------------------------------------------------------------

    The National Wildlife Federation challenged this regulation as 
being inconsistent with sections 515(b)(10) and (24) of the Act, 
primarily because it deleted the biological community criterion for 
non-perennial stream protection. However, the court rejected that 
challenge, finding without elaboration that the ``regulation is not in 
conflict with either section 515(b)(10) or 515(b)(24).'' \85\ The court 
also noted that the Secretary had properly justified the rule change on 
the grounds that the previous rule was confusing and difficult to apply 
without protecting areas of little biological significance.

Round II, 21 ERC 1725, 1741-1742 (D.D.C. 1984).

    Industry also challenged the 1983 version of 30 CFR 817.57(a) to 
the extent that it included all underground mining activities. However, 
industry withdrew its challenge when the Secretary stipulated that the 
rule would apply only to surface lands and surface activities 
associated with underground mining.\86\

    Historically, we and some state regulatory authorities applied the 
1983 stream buffer zone rule in a manner that allowed the placement of 
excess spoil fills, refuse piles, slurry impoundments, and 
sedimentation ponds in intermittent and perennial streams within the 
permit area. However, as discussed at length in the preamble to a 2004 
proposed rule,\87\ which we never finalized, there has been 
considerable controversy over the proper interpretation of both the 
Clean Water Act and our 1983 rules as they apply to the placement of 
fill material in or near perennial and intermittent streams.
---------------------------------------------------------------------------

    \87\ See 69 FR 1038-1042 (Jan. 7, 2004).
---------------------------------------------------------------------------

    One interpretation of the 1983 stream buffer zone rules appears in 
our annual oversight reports for West Virginia for 1999 and 2000, which 
state that the stream buffer zone rule does not apply to the footprint 
of a fill placed in a perennial or intermittent stream as part of a 
surface coal mining operation. On June 4, 1999, in West Virginia 
Highlands Conservancy v. Babbitt, Civ. No. 1:99CV01423 (D.D.C.), the 
plaintiffs challenged the validity of that interpretation, alleging 
that it constituted rulemaking in violation of the Administrative 
Procedure Act.
    However, on August 9, 1999, OSMRE, the U.S. Army Corps of 
Engineers, EPA, and the West Virginia Division of Environmental 
Protection (WVDEP) signed a memorandum of understanding (MOU) in which 
all four agencies in effect agreed to an interpretation that allowed 
valley fills in intermittent or perennial streams to be approved only 
if the buffer zone findings were made for the filled stream segments. 
The MOU also stated that the Clean Water Act Section 404(b)(1) 
Guidelines at 40 CFR part 230 contain requirements comparable to the 
findings required by the combination of OSMRE's 1983 stream buffer zone 
rule and the West Virginia stream buffer zone rule. Consequently, the 
MOU found that, ``where a proposed fill is consistent with the 
requirements of the Section 404(b)(1) Guidelines and applicable 
requirements for Section 401 certification of compliance with water 
quality standards, the fill would also satisfy the criteria for 
granting a stream buffer zone variance under SMCRA and WVDEP 
regulations.'' \88\ As a result of the signing of the MOU, the court 
approved an unopposed motion to dismiss the case mentioned above \89\ 
as moot in an order filed September 23, 1999.

---------------------------------------------------------------------------

    In a lawsuit filed in the U.S. District Court for the Southern 
District of West Virginia in July 1998, plaintiffs asserted that the 
1983 stream buffer zone rule should be interpreted to allow mining 
activities through a perennial or intermittent stream or within the 
buffer zone for a perennial or intermittent stream only if the 
activities are minor incursions.\90\ They argued that the rule did not 
allow substantial segments of a perennial or intermittent stream to be 
buried underneath excess spoil fills or other mining-related 
structures.\91\ On October 20, 1999, the district court ruled in favor 
of the plaintiffs on this

[[Page 44449]]

point, holding that the West Virginia version of the stream buffer zone 
rule applies to all segments of a stream, including those segments 
within the footprint of an excess spoil fill, not just to the stream as 
a whole.\92\ The court stated that the construction of fills in 
perennial or intermittent streams is inconsistent with the language of 
the West Virginia counterpart to 30 CFR 816.57(a)(1), which provides 
that the regulatory authority may authorize surface mining activities 
within a stream buffer zone only after making certain findings, 
including a finding that the proposed activities would not ``adversely 
affect the normal flow or gradient of the stream, adversely affect fish 
migration or related environmental values, materially damage the water 
quantity or quality of the stream . . . .'' \93\ The court also 
concluded that, contrary to the August 1999 MOU, satisfaction of the 
Section 404(b)(1) Guidelines is not equivalent to satisfaction of the 
SMCRA buffer zone rule.\94\

interpret the 1983 version of the stream buffer zone rule, the brief 
for the federal appellants in that case included another interpretation 
of the regulation in their brief. In sum, the federal appellants 
supported an interpretation based on the district court decision and 
stated that 30 CFR 816.57 ``prohibits the burial of substantial 
portions of intermittent and perennial streams beneath excess mining 
spoil.'' \95\

    In a different case related to the issuance of a nationwide section 
404 permit under the Clean Water Act, the U.S. District Court for the 
Southern District of West Virginia stated in an opinion that SMCRA and 
the 1983 stream buffer zone rule do not authorize disposal of 
overburden in streams: ``SMCRA contains no provision authorizing 
disposal of overburden waste in streams, a conclusion further supported 
by the buffer zone rule.'' \96\ Yet, on appeal, the U.S. Court of 
Appeals for the Fourth Circuit rejected the district court's 
conclusion, stating that ``SMCRA does not prohibit the discharge of 
surface coal mining excess spoil in waters of the United States.'' \97\ 
The court further stated that ``it is beyond dispute that SMCRA 
recognizes the possibility of placing excess spoil material in waters 
of the United States even though those materials do not have a 
beneficial purpose.'' \98\

traditional interpretation of the [stream buffer zone] is in harmony

The 2008 Rule

    In 2004, we proposed a rule to revise the 1983 version of the 
stream buffer zone rule in order ``to clarify the circumstances in 
which mining activities such as the construction of excess spoil fills 
may be allowed within the [stream buffer zone]''.\101\ Although we 
abandoned this proposed rule, we proposed another rule in 2007, in part 
``to end the ambiguity in interpretation of the stream buffer zone 
rules and to ensure that regulatory authorities, mine operators, other 
governmental entities, landowners, and citizens all can have a common 
understanding of what the stream buffer zone rules do and do not 
require, consistent with underlying statutory authority.'' \102\

    \102\ 72 FR 48890, 48892 (Aug. 24, 2007).
---------------------------------------------------------------------------

    We subsequently adopted a final rule that revised the circumstances 
under which mining activities may be conducted in or near perennial or 
intermittent streams and established new requirements for the creation 
and disposal of excess spoil and coal mine waste. Among other things, 
the rule required that mining operations be designed to minimize the 
creation of excess spoil and that permit applicants consider a range of 
reasonable alternatives to the disposal of excess spoil and coal mine 
waste in perennial or intermittent streams or their buffer zones and 
select the alternative with the least overall adverse impact on fish, 
wildlife, and related environmental values. With respect to activities 
in the stream itself, it replaced the findings in the 1983 rule with a 
requirement for a finding that avoiding disturbance of the stream is 
not reasonably possible. It also required a demonstration of compliance 
with the Clean Water Act before the permittee initiates mining 
activities in a perennial or intermittent stream if those activities 
require authorization or certification under the Clean Water Act. With 
respect to activities confined to the stream buffer zone, the rule 
replaced the findings in the 1983 rule with a requirement for a finding 
that avoiding disturbance of land within 100 feet of the stream either 
is not reasonably possible or is not necessary to meet the fish and 
wildlife and hydrologic balance protection requirements of the 
regulatory program. That rule, which we refer to in this preamble as 
the 2008 rule, took effect January 12, 2009. For a more detailed 
history of the 2008 rule, please refer to the discussion in the 
preamble to that rule.\103\

Litigation Concerning the 2008 Rule

    Shortly after publication of the 2008 rule, ten environmental 
organizations challenged the validity of the rule. See Coal River 
Mountain Watch v. Salazar (``Coal River''), No. 08-2212 (D.D.C., filed 
Dec. 22, 2008) and National Parks Conservation Ass'n v. Salazar 
(``NPCA''), No. 09-115 (D.D.C., filed Jan. 16, 2009).
    In NPCA, the Federal Government filed a motion on April 27, 2009, 
for voluntary remand and vacatur of the 2008 rule. The motion was based 
on the Secretary's determination that OSMRE

[[Page 44450]]

erred in failing to initiate consultation with the U.S. Fish and 
Wildlife Service (FWS or the Service) under section 7(a)(2) of the 
Endangered Species Act, 16 U.S.C. 1536(a)(2), to evaluate possible 
effects of the 2008 rule on threatened and endangered species. In Coal 
River, the Federal Government filed a motion on April 28, 2009, to 
dismiss the complaint as moot if the court granted the motion in NPCA.
    On August 12, 2009, the court denied the Federal Government's 
motion in NPCA, holding that, absent a ruling on the merits, 
significant new evidence, or consent of all the parties, a grant of 
vacatur would allow the government to improperly bypass the procedures 
set forth in the Administrative Procedure Act, 5 U.S.C. 551 et seq., 
for repealing an agency rule. On the same date, the court denied the 
Federal Government's motion to dismiss in Coal River. See Nat'l Parks 
Conservation Ass'n v. Salazar, 660 F. Supp. 2d 3, 4 (D.D.C. 2009).
    On March 19, 2010, the parties involved in the NPCA and Coal River 
litigation signed a settlement agreement in which the Secretary agreed 
to make best efforts to sign a proposed rule to amend or replace the 
2008 rule within a year and sign a final rule within approximately 18 
months. On April 2, 2010, the court granted the parties' motion to hold 
in abeyance further judicial proceedings concerning the 2008 rule to 
allow time for us to conduct this rulemaking. However, for a variety of 
reasons, the Secretary had not yet published a proposed rule as of the 
beginning of 2013. Given this delay, on March 19, 2013, the court 
granted the plaintiffs' motions to resume the litigation.
    On February 20, 2014, the court vacated the 2008 rule because 
``OSM's determination that the revisions to the stream protection rule 
encompassed by the 2008 Rule would have no effect on threatened and 
endangered species or critical habitat was not a rational conclusion'' 
and that therefore our failure to initiate consultation on the 2008 
rule was a violation of section 7(a)(2) of the Endangered Species Act.

proceedings consistent with the decision.\105\ The court's decision 
also stated that vacatur of the 2008 rule resulted in reinstatement of 
the rule in effect before the vacated rule took effect.\106\ In 
response, OSMRE published a notice of vacatur in the Federal 
Register.\107\ Therefore, the proposed rule that we are publishing 
today uses the pre-2008 rules as the baseline for all proposed changes.

The 2009 Memorandum of Understanding

    As mentioned above, on June 11, 2009, the Secretary, the 
Administrator of the EPA, and the Acting Assistant Secretary of the 
Army (Civil Works) entered into an MOU \108\ implementing an 
interagency action plan designed to significantly reduce the harmful 
environmental consequences of surface coal mining operations in six 
Appalachian states,\109\ while ensuring that future mining remains 
consistent with federal law. Among other things, in the MOU we 
committed to review our ``existing regulatory authorities and 
procedures to determine whether regulatory modifications should be 
proposed to better protect the environment and public health from the 
impacts of Appalachian surface coal mining.'' It also provides that, at 
a minimum, we will consider revisions to the 2008 rule and our 
regulatory requirements concerning approximate original contour.\110\
---------------------------------------------------------------------------

    \109\ Kentucky, Ohio, Pennsylvania, Tennessee, Virginia, and 
West Virginia.
    \110\ The MOU also stated that we would develop guidance 
clarifying how the 1983 stream buffer zone rule would be applied to 
reduce adverse impacts on streams if the court granted the 
Government's motion in NPCA for remand and vacatur of the 2008 rule. 
However, the court in NPCA did not grant the specific motion 
mentioned in the MOU. See Nat'l Parks Conservation Ass'n v. Salazar, 
660 F. Supp. 2d 3, 4 (D.D.C. 2009).
---------------------------------------------------------------------------

    The proposed rule that we are publishing today is, in part, the 
result of our review of existing regulatory authorities and procedures 
as promised in the MOU. The proposed rule would replace the vacated 
2008 rule and the reinstated pre-2008 rules. However, we have decided 
not to propose any major changes to our permitting requirements and 
performance standards concerning approximate original contour 
restoration at this time because of cost concerns and perceived 
difficulty of implementation.\111\
---------------------------------------------------------------------------

    \111\ The draft EIS and draft regulatory impact analysis for 
this rulemaking evaluate potential changes to approximate original 
contour requirements, including the addition of landforming and 
digital modeling requirements, as part of Alternative 4.
---------------------------------------------------------------------------

The Advance Notice of Proposed Rulemaking (ANPRM)

    On November 30, 2009 (74 FR 62664-64668), we published an advance 
notice of proposed rulemaking, consistent with the MOU and National 
Parks Conservation Association v. Salazar, 660 F. Supp. 2d 3, 4 (D.D.C. 
2009). Specifically, the notice described ten alternatives for revising 
the 2008 rule and related rules and invited the public to comment on 
those alternatives and to suggest other ways that the 2008 rule should 
be revised to better protect streams and implement the MOU. We also 
invited the public to identify provisions of our regulations other than 
the 2008 rule that should be revised to better protect the environment 
and the public from the impacts of Appalachian surface coal mining. We 
received approximately 32,750 comments during the 30-day comment 
period.
    After evaluating the comments that we received on the ANPRM, re-
examining the 2008 rule, and re-examining practices in and outside 
Appalachia, we determined that development of a comprehensive stream 
protection rule would be the most appropriate and effective method of 
better achieving the purposes and requirements of SMCRA as well as the 
goals set forth in the MOU and the ANPRM. Consequently, we are 
proposing a rule that would identify measures that mine operators and 
SMCRA regulatory authorities must take to prevent or minimize mining-
related impacts on streams and fish, wildlife and related environmental 
values.
    Thus, the scope of this proposed rule is broader than the scope of 
the 2008 rule, which focused primarily on excess spoil handling, coal 
mine waste disposal, and activities conducted in or near streams. 
Consistent with the broader scope of the proposed rule, we are 
preparing a new EIS, rather than supplementing the EIS prepared for the 
2008 rule. We also are consulting with the U.S. Fish and Wildlife 
Service as required by section 7 of the Endangered Species Act. 
Furthermore, if we determine that adoption of this proposed rule may 
affect species under the jurisdiction of the National Marine Fisheries 
Service (NMFS), we will consult with NMFS, which is

[[Page 44451]]

responsible for administration and enforcement of the Endangered 
Species Act with respect to anadromous and marine species.
    Comments that we received in response to the ANPRM differed as to 
whether the proposed rule should be national in scope or whether it 
should be limited to central Appalachia or to steep-slope mining 
operations. After evaluating those comments, we have decided to propose 
rules that are national in scope because streams are ecologically 
important regardless of topography or where they are located in the 
country. Measures to protect the quality and quantity of streamflow, 
both from surface sources and groundwater discharges, are likewise 
important regardless of topography or location. In addition, section 
101(g) of SMCRA states that ``[national] surface mining and reclamation 
standards are essential in order to insure that competition in 
interstate commerce among sellers of coal produced in different States 
will not be used to undermine the ability of the several States to 
improve and maintain adequate standards on coal mining operations 
within their borders.'' In other words, national standards are 
necessary because they define a set of environmental protection 
requirements that a state cannot relax as an incentive to coal 
producers to either continue to mine coal in the state or to relocate 
to the state.
    Protecting our water resources and preventing water pollution is 
important everywhere, especially in the arid and semiarid West and 
portions of the country that are experiencing droughts. There is a need 
for consistent, scientifically-valid documentation of the premining 
physical, chemical, and biological condition of streams and the impacts 
of mining and reclamation on those streams. All permits should include 
plans for stream protection or restoration that require use of best 
practices to either maintain the ecological condition of streams or 
restore both the physical form and the ecological function of affected 
streams. The proposed rule is sufficiently flexible to accommodate the 
different regions where coal is mined and the differences in streams 
found in those regions.
    In addition, the proposed rule would address some concerns that 
commenters on the ANPRM expressed with respect to other provisions of 
our regulations that are not necessarily directly related to stream 
protection, but that are important in terms of protecting the 
hydrologic balance or better achieving other requirements and purposes 
of SMCRA. We also propose to reorganize, revise, and streamline our 
rules to improve their readability and internal consistency, to update 
or remove obsolete provisions, to remove redundant and unneeded 
provisions, to be consistent with court decisions, and to incorporate 
plain language principles.

VII. Why does the proposed rule include protective measures for 
ephemeral streams?

    Unlike the regulations implementing the Clean Water Act, the 
existing regulations implementing SMCRA contain no specific protections 
for ephemeral streams. As summarized in Part II of this preamble, 
scientific studies completed since the enactment of SMCRA and the 
adoption of our existing rules have documented the importance of 
headwater streams, including ephemeral streams, in maintaining the 
ecological health and function of streams downgradient of headwater 
streams. EPA recently completed a literature review of the importance 
of headwater streams and published a report summarizing the findings of 
more than 1,200 peer-reviewed studies.\112\ With some exceptions, the 
report generally does not differentiate between the various types of 
headwaters streams, which consist of a mix of perennial, intermittent, 
and ephemeral streams, but it does emphasize that ephemeral streams are 
an important component of headwaters streams and that they have an 
effect on the form and function of downstream channels and aquatic 
life. Consistent with the findings of this report and other studies, 
our proposed rule includes some protections for ephemeral streams, 
tailored to their hydrologic and ecological functions.

June 16, 2015).
---------------------------------------------------------------------------

    We also are considering adopting an alternative that would provide 
equal protection to all streams, without regard to whether the stream 
is perennial, intermittent, or ephemeral. We invite comment on whether 
we should adopt this alternative in the final rule and, if so, whether 
we should extend all the protections that this proposed rule would 
afford to perennial and intermittent streams to ephemeral streams or 
whether we should instead scale back those protections to avoid undue 
adverse impacts on the mining industry, while still providing improved 
environmental protection to all streams compared with the existing 
regulations.

A. What are the findings of the EPA report?

    The report states that the evidence unequivocally demonstrates that 
the stream channels, riparian wetlands, floodplain wetlands, and open 
waters that together form river networks are clearly connected to 
downstream waters in ways that profoundly influence downstream water 
integrity. According to the authors, the body of literature documenting 
connectivity and downstream effects is most abundant for perennial and 
intermittent streams and for riparian and floodplain wetlands. However, 
the report states that, although less abundant, the evidence for 
connectivity and downstream effects of ephemeral streams is strong and 
compelling, particularly in context with the large body of evidence 
supporting the physical connectivity and cumulative effects of 
channelized flows that form and maintain stream networks.\113\
---------------------------------------------------------------------------

    \113\ Id. at ES-7.
---------------------------------------------------------------------------

    The report identifies five principal contributions of ephemeral 
streams: (1) Providing streamflow to larger streams; (2) conveying 
water into local storage compartments such as ponds, shallow aquifers, 
or streambanks that are important sources of water for maintenance of 
the baseflow in larger streams; (3) transporting sediment, woody 
debris, and nutrients; (4) providing the biological connectivity that 
is necessary either to support the life cycle of some invertebrates or 
to facilitate the transport of terrestrial invertebrates that serve as 
food resources in downstream communities; and (5) influencing 
fundamental biogeochemical processes such as the assimilation and 
transformation of nitrogen that may otherwise have detrimental impacts 
on downstream communities. The report's explanation of these 
contributions is summarized below. In addition, headwater streams, 
including ephemeral and intermittent streams, shape downstream channels 
by accumulating and gradually or episodically releasing stored 
materials such as sediment and large woody debris.\114\ These materials 
help structure stream and river channels by slowing the flow of water 
through channels and providing substrate and habitat for aquatic 
organisms.\115\

Providing Streamflow to Larger Streams
    Ephemeral streams are hydrologically connected to downstream waters 
via channels that convey surface and subsurface water in direct 
response to precipitation. Moreover, these streams are the defining 
characteristic of many watersheds in arid and semi-arid regions of the 
United States; thus serving a critical role in the maintenance of water 
resources.\116\

Hydrological Significance of Ephemeral and Intermittent Streams in 
the Arid and Semi-Arid American Southwest. Office of Research and 
Development, Washington, DC Final Report No. EPA/600/R-08/134 
(2008).
---------------------------------------------------------------------------

Conveyance of Water Into Local Storage Compartments
    Ephemeral streams may convey water to local storage compartments, 
such as ponds, shallow aquifers, and streambanks, and recharge regional 
alluvial aquifers, depending upon the frequency, duration, magnitude, 
and timing of precipitation events. These local storage compartments 
are important sources of water for maintaining baseflow in perennial 
streams. Streamflow typically depends on the delayed (i.e., lagged) 
release of shallow groundwater from local storage, especially during 
dry periods and in areas with shallow groundwater tables and pervious 
subsurfaces. Relative to their cumulative surface area, an inordinate 
amount of groundwater recharge occurs in headwater ephemeral and 
intermittent channels within arid drainage basins. Furthermore, in the 
southwestern United States, short-term shallow groundwater storage in 
alluvial floodplain aquifers, with gradual release into stream 
channels, is a major source of annual flow in rivers.\117\

Transport of Sediment and Nutrients
    Ephemeral streams frequently contain boulders and woody debris that 
entrain and store loose, unconsolidated sediment during smaller 
precipitation events that is subsequently released during infrequent, 
high-magnitude precipitation events. Because of the abundance and 
distribution of headwater streams, sediment storage and transport by 
those streams can have a substantial cumulative effect on downstream 
waters; headwater streams are important sediment sources for 
maintaining channels and floodplains.\118\ Similarly, headwater streams 
are important sources of organic matter (organic carbon) that serves as 
a downstream food source for aquatic life forms such as benthic 
macroinvertebrates and that enhances the fertility of agriculture on 
alluvial fans where some of the organic matter is deposited.\119\

Biological Connectivity
    Headwaters streams, including ephemeral streams, play an important 
role in the dispersal of genetic material and production and transport 
of food resources. For example, headwaters streams provide habitat that 
is critical for completion of one or more life-cycle stages of many 
aquatic and semiaquatic species capable of moving throughout water 
networks. These streams provide habitat for completion of complex life 
cycles. They also provide a refuge from predators, competitors, 
parasites, or adverse physical conditions in downstream waters.\120\

    Because biological connections often result from passive transport 
of organisms or their products with water flow, biological connectivity 
often depends on hydrologic connectivity. Many living organisms, 
however, also can actively move with or against water flow; others 
disperse actively or passively over land by walking, flying, drifting, 
or ``hitchhiking.'' All of these organism-mediated connections form the 
basis of biological connectivity between headwater streams and 
downstream waters. Biological connections between upstream and 
downstream reaches can affect downstream waters via multiple pathways 
or functions. For organisms capable of significant upstream movement, 
headwater streams, including ephemeral and intermittent streams, can 
increase both the amount and quality of habitat available to those 
organisms. Many organisms require different habitats for different 
resources (e.g., food, spawning habitat, overwintering habitat), and 
thus move throughout the river network--both longitudinally and 
laterally--over their life cycles, with some requiring dry channels to 
complete part of their life cycle. Furthermore, dry stream channels can 
facilitate dispersal of aquatic invertebrates by serving as dispersal 
corridors for terrestrial adult forms. Headwater streams also provide 
food resources to downstream waters, especially in the form of 
terrestrial invertebrates that accumulate in intermittent and ephemeral 
streams during dry periods and are then transported downstream by storm 
flows during and after a precipitation event.\121\

Biogeochemical Processes
    There is strong evidence that headwater streams function as 
nitrogen sources (via export) and sinks (via uptake and transformation) 
for river networks. For example, one study estimated that rapid cycling 
of nutrients, including nitrogen, in small streams with no agricultural 
or urban impacts removed 20-40% of the nitrogen that otherwise would be 
delivered to downstream waters. Nutrients, including nitrogen, are 
necessary to support aquatic life, but excess nutrients lead to 
eutrophication and hypoxia, in which over-enrichment causes dissolved 
oxygen concentrations to fall below the level necessary to sustain most 
aquatic animal life in the stream and streambed. Thus, the influence of 
streams on nutrient loads can have significant repercussions for 
hypoxia in downstream waters.\122\

B. What specific rule changes are we proposing with respect to 
ephemeral streams?

    We propose to require that the permit applicant identify and map 
all ephemeral streams within the proposed permit and adjacent areas. 
The applicant must describe the physical and hydrologic characteristics 
of those streams in detail, as well as any associated vegetation in the 
riparian zone if one exists. In addition, the applicant must assess the 
biological condition of a representative sample of those ephemeral 
streams. See proposed 30 CFR 780.19(c)(6) and 784.19(c)(6).
    We also propose to require that the significance of ephemeral 
streams be evaluated during the permitting process as part of the 
determination of the probable hydrologic consequences of mining and the 
cumulative hydrologic impact assessment. See proposed 30 CFR 780.20, 
780.21, 784.20, and 784.21.
    We further propose to specify that the backfilling and grading plan 
in the reclamation plan required by proposed 30 CFR 780.12(d) and 
784.12(d) must include contour maps, cross-sections, or models that 
show in detail the anticipated final surface configuration, including 
drainage patterns, of the proposed permit area. Proposed 30 CFR 
780.28(c)(1) and 784.28(c)(1) would require that the postmining 
drainage pattern, including ephemeral streams, be similar to the 
premining drainage pattern, with limited exceptions.

[[Page 44453]]

    Under proposed 30 CFR 780.28(b)(3) and 784.28(b)(3), the 
reclamation plan for an operation that proposes to disturb a perennial, 
intermittent, or ephemeral stream, or the surface of land within 100 
feet of that stream, must include the planting of native species, 
including, when appropriate, species adapted to and suitable for 
planting in riparian zones, within a corridor at least 100 feet in 
width on each side of the stream as part of the reclamation process 
following the completion of mining activities. The riparian corridor 
requirement would not apply to prime farmland or when a corridor would 
be inconsistent with an approved postmining land use that is actually 
implemented before expiration of the revegetation responsibility 
period. Nor would it apply to stream segments that are buried beneath 
an excess spoil fill or a coal mine waste disposal facility.

VIII. Overview and Tabular Summaries of Proposed Revisions and 
Organizational Changes

    The following derivation tables summarize the organizational 
changes in the proposed rule, relative to the existing rules. They also 
indicate whether we propose to revise the rule text in each 
redesignated section or paragraph. The organizational changes serve 
several purposes, including--
     Breaking up overly long sections and paragraphs into 
multiple shorter sections and paragraphs for ease of reference and 
improved comprehension.
     Renumbering sections in the underground mining rules to 
align their numbering with the corresponding sections in the surface 
mining rules. This change would greatly improve ease of reference and 
the user-friendliness of our rules.
     Moving permitting requirements from subchapter K 
(performance standards) to subchapter G to consolidate permitting 
requirements in subchapter G.
     Restructuring subchapter G to better distinguish between 
baseline information requirements and reclamation plan requirements.
     Removing redundant, suspended, and obsolete provisions.
    The following table is organized in the numerical order of the 
existing rule citations. It includes only those provisions of the 
existing regulations that we propose to move or remove.

    In general, we drafted the proposed rule using plain language 
principles, consistent with section 501(b) of SMCRA, 30 U.S.C. 1251(a), 
which provides that regulations must be ``concise and written in plain, 
understandable language,'' and Executive Order 13563, which provides 
that our regulatory system ``must ensure that regulations are 
accessible, consistent, written in plain language, and easy to 
understand.'' \123\ In addition, a June 1, 1998, Executive Memorandum 
on Plain Language in Government Writing \124\ requires the use of plain 
language in all proposed and final rulemaking documents published after 
January 1, 1999. The Office of the Federal Register also encourages the 
use of plain language in writing regulations, as set forth in detail at 
www.plainlanguage.gov and associated links.

    \123\ 76 FR 3821 (Jan. 21, 2011).
    \124\ 63 FR 31883-31886 (Jun. 10, 1998).
---------------------------------------------------------------------------

    Plain language requirements vary from one document to another, 
depending on the intended audience. Plain language documents have 
logical organization and easy-to-read design features like short 
sections, short sentences, tables, and lots of white space. They use 
common everyday words (except for necessary technical terms), pronouns, 
the active voice, and a question-and-answer format when feasible.
    The proposed rule and preamble use the pronouns ``we,'' ``us,'' and 
``our'' to refer to OSMRE, and the pronouns ``I,'' ``you,'' and 
``your'' to refer to a permit applicant or permittee. We avoid use of 
the word ``shall'' in the proposed rule and preamble, except in quoted 
material. Instead, we use ``must'' to indicate an obligation, ``will'' 
to identify a future event, and ``may not'' to convey a prohibition.
    We invite comment on how we could more fully incorporate plain 
language principles.

IX. How do we propose to revise specific provisions of our existing 
regulations?

    In this portion of the preamble, we discuss selected provisions of 
our proposed rule in the order in which the regulations that we propose 
to revise would appear in Title 30, Chapter VII of the Code of Federal 
Regulations. In general, we do not discuss proposed organizational 
changes (see Part VIII of this preamble for a listing of organizational 
changes), nonsubstantive editorial revisions (e.g., plain language 
changes, correction of grammatical errors, and syntax improvements), 
cross-reference changes, or revisions of a minor nature. No substantive 
change in meaning is intended for proposed revisions made in accordance 
with plain language principles.

A. Section 700.11(d): Termination and Reassertion of Jurisdiction

    The basis and purpose for our termination-of-jurisdiction rules is 
set forth in the preamble to the 1988 version of these rules. See 53 FR 
44356-44363 (Nov. 2, 1988). We propose to revise paragraph (d)(1) of 
the existing rules by removing the phrase ``the reclaimed site of'' 
from the existing introductory language because the regulatory 
authority's jurisdiction extends to the entire surface coal mining and 
reclamation operation, not just to the lands disturbed and reclaimed by 
the operation. Hence, any decision to terminate jurisdiction likewise 
should extend to the entire operation.
    We propose to improve the structure of the existing rule by placing 
the termination of jurisdiction requirements for initial program 
operations in paragraph (d)(1) and the requirements for permanent 
program operations in paragraph (d)(2). We also propose to add a 
provision to paragraph (d)(2)(ii) to reflect the proposed addition to 
30 CFR part 800 of provisions concerning financial assurances for 
treatment of long-term discharges. In particular, we propose to allow 
the regulatory authority to terminate jurisdiction over all portions of 
a minesite and all aspects of the operation, except treatment-related 
facilities and obligations, once the permittee posts an acceptable 
financial assurance under proposed 30 CFR 800.18 to guarantee treatment 
of all long-term discharges. Termination of jurisdiction may not occur 
until all performance bonds for the remainder of the permit area are 
fully released. Our proposed rule would improve the efficiency of 
regulatory authorities by eliminating unnecessary inspections of

[[Page 44467]]

the portion of the permit area that has been fully reclaimed. It also 
would eliminate the need for federal oversight of those sites and allow 
the property owner to acquire full control over the land. Continuing to 
conduct inspections of a fully-reclaimed minesite or of fully-completed 
operations would divert scarce resources from unreclaimed sites and 
other regulatory program responsibilities.
    Because of the restructuring described above, we propose to 
redesignate existing paragraph (d)(2) as paragraph (d)(3). This 
paragraph provides that the regulatory authority must reassert 
jurisdiction if the termination was based upon fraud, collusion, or 
misrepresentation of a material fact. We also propose to revise this 
provision to clarify that it applies to both intentional and 
unintentional misrepresentations of a material fact, including the 
subsequent discovery of a discharge that requires treatment. Our 
proposed revision is consistent with the decision of the U.S. Court of 
Appeals for the District of Columbia Circuit that upheld our 
termination of jurisdiction rules.\125\

Cir. 1991); see also Brief for the Secretary at 27 n. 11.
---------------------------------------------------------------------------

    In addition, proposed paragraph (d)(4) would specify that the 
termination of jurisdiction provisions of proposed paragraphs (d)(1) 
and (2) do not apply to proposed 30 CFR 817.40, which contains the 
domestic water supply replacement requirements for underground mines, 
or to the structural damage repair or compensation requirements of 30 
CFR 817.121(c)(2). Proposed paragraph (d)(4) is consistent with the 
decision of the U.S. District Court for the District of Columbia 
concerning termination of jurisdiction for the water replacement and 
subsidence damage correction obligations imposed on underground mines 
by section 720(a) of SMCRA.\126\ In that decision, the court held that 
those obligations are not subject to the termination of jurisdiction 
provisions of 30 CFR 700.11(d).\127\

---------------------------------------------------------------------------

    Finally, we propose to revise existing 30 CFR 700.11(d)(1)(ii), 
which we propose to redesignate as 30 CFR 700.11(d)(2), to specify that 
the requirements of that paragraph also apply to coal exploration 
activities, as was intended when we first published our termination-of-
jurisdiction rules in 1988.\128\ The phrase ``or of a coal exploration 
site'' was inadvertently omitted from the published text of existing 30 
CFR 700.11(d)(1). We plan to correct this inadvertent error when 
publishing a final rule. However, we invite comment on whether we 
should instead limit the scope of that requirement to termination of 
jurisdiction for coal exploration permits issued under 30 CFR 772.12. 
The rationale for a limitation of this nature is that, unlike coal 
exploration permits, coal exploration notices do not require regulatory 
authority approval and do not involve activities that substantially 
disturb the land surface.

B. Section 701.5: Definitions

    This portion of the preamble discusses, in alphabetical order, each 
definition that we propose to add, remove, or revise.
Acid Drainage
    We propose to revise the definition of this term to clarify that 
the same definition applies to the term ``acid mine drainage.'' We also 
propose to correct the terminology in the definition to comport with 
the terminology used in SMCRA. Specifically, we propose to replace the 
undefined term ``surface coal mine and reclamation operation'' with 
``surface coal mining and reclamation operations,'' which is defined at 
section 701(27) of SMCRA,\129\ as well as in 30 CFR 700.5.
---------------------------------------------------------------------------

    \129\ 30 U.S.C. 1291(27).
---------------------------------------------------------------------------

Adjacent Area
    Proposed paragraph (a) would revise and broaden the existing 
definition of ``adjacent area'' to ensure that it includes all areas 
outside the proposed or actual permit area within which there is a 
reasonable possibility of adverse impacts from surface coal mining 
operations or underground mining activities, as applicable. The 
existing definition limits the adjacent area to areas where adverse 
impacts could reasonably be expected to occur and, for underground 
mining, to areas where subsidence is probable. Those limits are too 
restrictive because they effectively limit baseline data collection and 
monitoring to the area in which adverse impacts are almost certain to 
occur. If impacts occur outside that area, there will be no baseline 
data against which to evaluate those impacts. Therefore, we propose to 
revise the definition to include areas where impacts are reasonably 
possible, as determined by the regulatory authority on a site-specific 
basis.
    The revised definition would emphasize that the term ``adjacent 
area'' is both site-specific and context-specific. As in the existing 
definition, the nature of the resource and the context in which the 
regulations use the term ``adjacent area'' would determine the size and 
dimensions of the adjacent area for that resource. Our regulations 
require that each permit application contain information concerning 
historic resources, fish and wildlife resources, surface water, 
groundwater, and geology for the proposed permit and adjacent areas. 
The size and boundaries of the adjacent area in the context of historic 
resources, which are stationary, may differ substantially from the size 
and boundaries of the adjacent area for surface water, for which flow 
patterns are determined by topography, and the size and boundaries of 
the adjacent area for groundwater, which has a migration pattern 
determined by geology.
    Proposed paragraph (b) would specify that the adjacent area for an 
underground mine includes both the area overlying the proposed 
underground workings and the area within a reasonable angle of draw 
\130\ from the perimeter of the underground workings. This provision 
would ensure that the adjacent area includes all areas in which 
subsidence may reasonably occur.
---------------------------------------------------------------------------

    \130\ The angle of draw is the angle between the outside edge of 
an underground mine void and the point on the surface to which 
subsidence may extend when the strata overlying the mine void 
collapse. Draw usually proceeds at an angle of 65-75[deg] to the 
horizontal. This definition is adapted from: Ailsa Allaby and 
Michael Allaby. ``angle of draw.'' A Dictionary of Earth Sciences. 
1999. Retrieved February 02, 2015, from Encyclopedia.com: https://www.encyclopedia.com/doc/1O13-angleofdraw.html.
---------------------------------------------------------------------------

    Proposed paragraph (c) would specify that, for all operations, the 
adjacent area also includes the area that might be affected physically 
or hydrologically by dewatering existing underground mine pools as part 
of surface or underground mining operations, plus the area that might 
be affected physically or hydrologically by mine pools that develop 
after cessation of mining activities.
    We considered adding another paragraph to specify that, in the 
context of surface-water resources, the adjacent area would include, at 
a minimum, the HUC-12 (U.S. Geological Survey 12-digit Watershed 
Boundary Dataset) \131\ watershed or watersheds in which the proposed 
or actual permit area is located. However, we decided against including 
that provision because HUC boundaries are fixed and do not vary with 
the location of the mining operation. Surface-water data collected from 
those portions of the HUC-12 watershed that are upgradient of the

[[Page 44468]]

proposed operation would be of little or no value in making permitting 
decisions or evaluating the impacts of mining. In addition, HUC-12 
watersheds typically contain between 10,000 and 40,000 acres, which is 
much larger than the area necessary or appropriate to establish 
baseline conditions for most coal mines, which are only tens or 
hundreds of acres in size.
---------------------------------------------------------------------------

    \131\ See https://water.usgs.gov/GIS/huc.html (last accessed 
September 8, 2014).
---------------------------------------------------------------------------

    We invite comment on whether the definition should prescribe a more 
appropriate minimum size for the adjacent area for surface-water 
resources and, if so, how that minimum size should be determined. For 
example, a 2002 OSMRE reference document on baseline data recommends 
that the adjacent area for surface water include both the surface-water 
runoff drainage area for the proposed operation and at least the next 
higher-order drainage area.
Approximate Original Contour
    We propose to revise the definition of this term to explain its 
scope and to incorporate plain language principles. In concert with 
these changes, we propose to clarify that the term refers to the 
general surface configuration of the land within the permit area as it 
existed before any mining, not the configuration that existed 
immediately prior to the proposed or current operation. We intend this 
change to operate as a requirement that operations backfill and regrade 
previously mined areas to closely resemble the general surface 
configuration that existed before any mining, except as provided in 30 
CFR 816.106 or 817.106. This approach is consistent with section 
515(b)(2) of SMCRA,\132\ which requires that surface coal mining and 
reclamation operations be conducted so as to ``restore the land 
affected to a condition capable of supporting the uses which it was 
capable of supporting prior to any mining . . . .'' In ruling on the 
regulations implementing that provision of the Act, the U.S. District 
Court for the District of Columbia subsequently held that ``[t]he use 
of the word `any' indicates that Congress intended the operator to 
restore the land to the condition that existed before it was ever 
mined.'' \133\

(Envtl. Law Inst.) 20208.
---------------------------------------------------------------------------

    Our proposed addition of the phrase ``within the permit area'' when 
referring to the general surface configuration is intended to clarify 
that determinations of approximate original contour must be made based 
on the general surface configuration of the permit area, not the 
general surface configuration of the surrounding area. The proposed 
addition is consistent with section 701(2) of SMCRA,\134\ which defines 
``approximate original contour'' as meaning ``that surface 
configuration achieved by backfilling and grading of the mined area so 
that the reclaimed area . . . closely resembles the general surface 
configuration of the land prior to mining and blends into and 
complements the drainage pattern of the surrounding terrain . . . .'' 
The statutory definition clearly applies the term ``general surface 
configuration'' only to the area that is mined and reclaimed; it does 
not extend to the surrounding area. Instead, with respect to the 
surrounding area, the statutory definition requires that the general 
surface configuration of the reclaimed area blend into and complement 
the drainage pattern of the surrounding terrain. Limiting the scope of 
the term ``general surface configuration'' to the mined and reclaimed 
area also is consistent with the discussion and diagrams in the 
legislative history of SMCRA. See H.R. Rep. No. 94-45, at 94 (1975).
---------------------------------------------------------------------------

    \134\ 30 U.S.C. 1291(2).
---------------------------------------------------------------------------

    In addition, we propose to revise the definition to include an 
exception for excess spoil fills, consistent with a June 18, 1999, 
legal opinion from the Department of the Interior's Office of the 
Solicitor. That opinion confirmed that the AOC restoration requirements 
of SMCRA do not apply to the construction of excess spoil fills, in 
part because the statutory definition of approximate original contour 
in section 701(2) of SMCRA \135\ applies only to ``that surface 
configuration achieved by backfilling and grading of the mined area.'' 
Excess spoil fills are not part of the backfilling process and they are 
at least initially located outside the mined area. We also propose to 
add an exception for coal mine waste refuse piles because the same 
rationale applies to the construction of those piles. Furthermore, 
sections 515(b)(11) and 516(b)(4) of SMCRA \136\ clearly envision the 
construction of permanent coal mine waste refuse piles on the land's 
surface, but there is no requirement to restore the surface of that 
land to approximate original contour, nor would it be possible to do 
so. Instead, section 515(b)(11) of the Act \137\ requires that the 
operation ``assure the final contour of the waste pile will be 
compatible with natural surroundings and that the site can and will be 
stabilized and revegetated according to the provisions of the Act.'' 
Section 516(b)(4) \138\ includes similar language for refuse piles 
associated with underground mines.

    \138\ 30 U.S.C. 1266(b)(4).
---------------------------------------------------------------------------

    We also propose to revise the definition to clarify that, 
consistent with the legislative history, the potentially confusing 
placement of the phrase ``including any terracing or access roads'' in 
the statutory definition does not mean that terraces and access roads 
must be regraded to the approximate original contour. As explained in 
the legislative history of the definition of approximate original 
contour, Congress added this phrase to clarify that the AOC restoration 
requirement does not prohibit the construction of terraces or the 
retention of access roads on backfilled areas.\139\ Therefore, we 
propose to add language stating that the requirements of the definition 
do not prohibit the approval of terracing under 30 CFR 816.102 or 
817.102 or the retention of access roads under 30 CFR 816.150 or 
817.150.

---------------------------------------------------------------------------

    Finally, we propose to replace the cross-references to 30 CFR 
816.133 and 817.133 with cross-references to 30 CFR 780.24(b) and 
784.24(b), respectively. This change reflects our proposal to move the 
relevant portions of 30 CFR 816.133 and 817.133 to 30 CFR 780.24(b) and 
784.24(b), respectively.
Backfill
    We propose to add a definition of ``backfill'' to clarify the 
difference between backfill, excess spoil fills, and thick overburden 
returned to the mined-out area under 30 CFR 816.105, all of which have 
different permitting requirements and performance standards. We derived 
our proposed definition from the definition of ``backfill'' in A 
Dictionary of Mining, Mineral, and Related Terms (U.S. Bureau of Mines, 
1968). However, we modified that definition by tailoring it to coal 
mining and the purpose stated in the first sentence of this discussion. 
Specifically, we propose to define ``backfill,'' when used as a noun, 
as the spoil and waste materials used to fill the void resulting from 
an excavation created for the purpose of extracting coal from the 
earth. When used as a verb, the term would refer to the process of 
filling that void. The definition also would include all materials used 
to restore the approximate original contour of the mined-out area. We 
propose to

[[Page 44469]]

make conforming changes to the definition of excess spoil, which is 
discussed below under a separate heading.
Bankfull
    We propose to add a definition of this technical and scientific 
term because we use this term in our proposed regulations to more 
precisely fix the boundaries of stream buffer zones and riparian 
corridors and in our proposed stream restoration requirements. Under 
our proposed definition, bankfull would mean the water level or stage 
at which a stream, river, or lake is at the top of its banks and any 
further rise would result in water moving into the flood plain. The 
proposed definition parallels the one that appears in the National 
Weather Service glossary.\140\

---------------------------------------------------------------------------

Biological Condition
    We propose to add a definition of biological condition in 
conjunction with the new permitting requirements and performance 
standards concerning documentation, protection, and restoration of 
biological communities in streams. Specifically, we propose to define 
biological condition as a measure of the ecological health of a stream 
or segment of a stream as determined by the type, diversity, 
distribution, abundance, and physiological state of aquatic organisms 
and communities found in the stream or stream segment. The biological 
condition of a water body is the ultimate indicator of watershed health 
because aquatic organisms and communities reflect the cumulative 
conditions of all other watershed components and processes.\141\

    \141\ https://water.epa.gov/polwaste/nps/watershed/biotic.cfm 
(last accessed June 8, 2015).
---------------------------------------------------------------------------

    Our proposed rule would require application of a multimetric 
biological assessment and taxonomic assessment protocol to determine 
biological condition. See, e.g., proposed 30 CFR 780.19(e) and 
784.19(e). Multimetric indices include metrics such as species 
richness, complexity, and tolerance as well as trophic measures. They 
provide a quantitative comparison (often referred to as an index of 
biological or biotic integrity) of the ecological complexity of 
biological assemblages relative to a regionally-defined reference 
condition. For example, River Invertebrate Prediction and 
Classification System models quantify biological condition by comparing 
the observed taxa at a site to the taxa that would be expected to be 
present in the absence of human-caused stress.\142\
---------------------------------------------------------------------------

    \142\ Id.
---------------------------------------------------------------------------

    Our existing regulations do not specifically require collection of 
the baseline data necessary to determine the biological condition of 
streams. Consequently, the permit application often lacks specific 
descriptions of the aquatic community residing in streams within the 
permit and adjacent areas. The lack of baseline information on the 
biological condition of streams creates an impediment to determining 
whether the proposed operation has been designed to prevent material 
damage to the hydrologic balance outside the permit area, as required 
by sections 507(b) and 510(b)(3) of SMCRA.\143\ It also creates an 
impediment to evaluating whether the operation has been and is being 
conducted to minimize adverse impacts on fish, wildlife, and related 
environmental values, as required by sections 515(b)(24) and 516(b)(11) 
of SMCRA.\144\ Furthermore, preparation of a comprehensive cumulative 
hydrologic impact assessment is not always possible if the permit 
application does not include information on the biological condition of 
streams. While the information sometimes may be available from the 
agencies responsible for implementing the Clean Water Act, those 
agencies generally do not assess the cumulative loading of substances 
legally discharged into the receiving stream until the stream becomes 
impaired.

---------------------------------------------------------------------------

Cumulative Impact Area
    Sections 507(b)(11) and 510(b)(3) of SMCRA \145\ require that the 
regulatory authority prepare an assessment of the probable cumulative 
impact of all anticipated mining in the area upon the hydrology of the 
general area. In 1983, we adopted a definition of cumulative impact 
area to identify both the extent of the area that must be included in 
this evaluation and the scope of the term ``anticipated mining.'' \146\ 
The first sentence of the 1983 definition mentions only anticipated 
mining, while the second sentence includes existing operations in the 
list of the types of operations encompassed by the term ``anticipated 
mining.'' We propose to resolve this inconsistency by replacing the 
term ``anticipated mining'' with ``existing and anticipated mining'' or 
its equivalent.

---------------------------------------------------------------------------

    In addition, we propose to add language clearly specifying that the 
term ``mining'' includes both surface and underground mining 
operations. Discharges of water from underground mines can cause 
material damage to the hydrologic balance outside the permit area, as 
demonstrated by a 2010 incident in which water discharged from an 
underground mine resulted in a golden algae bloom in Dunkard Creek in 
West Virginia and Pennsylvania that caused a major fish kill.\147\ Our 
revised definition would clarify that the cumulative impact area 
includes the area within which the proposed or actual operation may 
interact with the impacts of all existing and anticipated surface and 
underground coal mining operations.

---------------------------------------------------------------------------

    We propose to restructure the definition for clarity. Proposed 
paragraphs (a) through (c) would specify the areas that must be 
included in the cumulative impact area.
    Proposed paragraph (a) would require that the cumulative impact 
area include the actual or proposed permit area. The addition of the 
``actual or proposed'' language reflects the fact that the cumulative 
impact area is a concept that applies both before and after permit 
issuance.
    Proposed paragraph (b) would require that the cumulative impact 
area include the HUC-12 (U.S. Geological Survey 12-digit Watershed 
Boundary Dataset) \148\ watershed or watersheds in which the actual or 
proposed permit area is located. We propose to add this provision to 
establish a bright-line standard for the minimum size of the cumulative 
impact area. For operations that straddle a ridgeline or other 
watershed boundary, the cumulative impact area must include, at a 
minimum, the HUC-12 watershed on each side of the ridgeline or other 
boundary.
---------------------------------------------------------------------------

    \148\ See https://water.usgs.gov/GIS/huc.html (last accessed 
September 8, 2014).
---------------------------------------------------------------------------

    Proposed paragraph (c) would provide that, in addition to the areas 
specified in proposed paragraphs (a) and (b), the cumulative impact 
area must include any other area within which impacts resulting from an 
actual or proposed surface or underground coal mining operation may 
interact with the impacts of all existing and anticipated surface and 
underground coal mining on surface-water and groundwater systems, 
including the impacts that existing and

[[Page 44470]]

anticipated mining will have during mining and reclamation and after 
final bond release. Proposed paragraphs (c)(1) through (6) would 
specify the minimum components of the term ``existing and anticipated 
mining.'' Proposed paragraphs (c)(1) through (3) are substantively 
identical to paragraphs (a) through (c) of the existing definition.
    Proposed paragraph (c)(4) would specify that ``anticipated mining'' 
includes any proposed surface or underground mining operation for which 
a person has submitted a request for an authorization, certification, 
or permit under the Clean Water Act. Inclusion of proposed operations 
for which the Clean Water Act authorization process has begun would 
assist in preparation of a more comprehensive analysis on the part of 
both the permit applicant or permittee and the regulatory authority.
    Proposed paragraph (c)(5) would modify paragraph (d) of the 
existing definition to clarify that anticipated mining includes all 
lands for which a resource recovery and protection plan has been either 
approved or submitted to and reviewed by the authorized officer of the 
Bureau of Land Management under 43 CFR 3482.1(b). The added language 
would clarify the point at which lands containing leased Federal coal 
must be included within the cumulative impact area.
    Proposed paragraph (c)(6) would specify that anticipated mining 
includes, for underground mines, all areas of contiguous coal reserves 
adjacent to an existing or proposed underground mine that are owned or 
controlled by the applicant. This addition is appropriate because, 
barring significant changes in economic or regulatory conditions, the 
mine very likely will be extended into those reserves in the future.
Ecological Function
    We propose to add a definition of this term in concert with our 
proposal to require that permittees restore the ecological function of 
the segments of perennial and intermittent streams through which they 
mine. Ecological function includes physical parameters, biological 
parameters, and a consideration of physical and biological interactions 
as nutrients and energy are collected and transferred down the stream 
continuum.\149\ Specifically, we propose to define this term as 
including the role that the stream plays in dissipating energy and 
transporting water, sediment, organic matter, and nutrients downstream. 
It also includes the ability of the stream ecosystem to retain and 
transform inorganic materials needed for biological processes into 
organic forms (forms containing carbon) and to oxidize those organic 
molecules back into elemental forms through respiration and 
decomposition. Finally, the term includes the role that the stream 
plays in the life cycles of plants, insects, amphibians (especially 
salamanders), reptiles, fish, birds, and mammals that either reside in 
the stream or depend upon it for habitat, reproduction, food, water, or 
protection from predators. The proposed definition is based upon a 
functional assessment guidebook that the U.S. Army Corps of Engineers 
developed for ephemeral and intermittent streams in central 
Appalachia.\150\ The biological condition of a stream is one measure of 
its ecological function.

---------------------------------------------------------------------------

Ephemeral Stream
    We propose to redefine ``ephemeral stream'' in a manner that is 
substantively identical to the manner in which the U.S. Army Corps of 
Engineers defines that term in Part F of the 2012 reissuance of the 
nationwide permits under section 404 of the Clean Water Act. See 77 FR 
10184, 10288 (Feb. 21, 2012). Adoption of a substantively identical 
definition would promote consistency in application and interpretation 
of that term under both SMCRA and Clean Water Act programs.
    We invite comment on whether the definition in the final rule 
should include language specifying that the U.S. Army Corps of 
Engineers has the ultimate authority to determine the point at which an 
ephemeral stream becomes an intermittent stream or a perennial stream 
and vice versa. Further, if the final rule includes language to that 
effect, we invite comment on whether the definition also should provide 
that any determination that the Corps makes concerning these transition 
points will be controlling for purposes of SMCRA regulatory programs. 
Commenters should discuss the applicability of two SMCRA provisions in 
this context. First, section 702(a) of SMCRA \151\ provides that 
``[n]othing in this Act shall be construed as superseding, amending, 
modifying, or repealing'' the Clean Water Act, any rule or regulation 
adopted under the Clean Water Act, or any state laws enacted pursuant 
to the Clean Water Act. Second, section 505(b) of SMCRA \152\ provides 
that any provision of any state law or regulation may not be construed 
to be inconsistent with SMCRA if it ``provides for more stringent land 
use and environmental controls and regulations of surface coal mining 
and reclamation operation[s] than do the provisions of this Act or any 
regulation issued pursuant thereto.'' In other words, should our 
regulations allow states to adopt and apply stream definitions in a 
manner that would protect a greater length of stream than would the 
Corps determinations?

    The primary difference between our existing definition and the 
Corps definition that we propose to adopt concerns the treatment of 
snowmelt. Our existing definition classifies streamflow in response to 
the melting of snow and ice as an ephemeral stream, whereas the Corps 
definition is silent on this point. The preamble to the Corps 
definition notes that the Corps declined to accept a recommendation 
from a commenter that streamflow resulting from snowmelt be classified 
as an ephemeral stream. The preamble explains that, while snowmelt may 
contribute to the flow of ephemeral streams, snowmelt also contributes 
to the flow of intermittent and perennial streams, especially in areas 
with deep snow packs. The preamble further states that the definition 
appropriately focuses on the duration of flow and that melting snow 
should not be considered a precipitation event because the development 
of a snowpack occurs over the course of a winter season. See 77 FR 
10184, 10262 (Feb. 21, 2012).
Excess Spoil
    Our existing rules define excess spoil as spoil material disposed 
of in a location other than the mined-out area. The definition excludes 
spoil used to achieve the approximate original contour or to blend the 
mined-out area with the surrounding terrain in non-steep slope areas. 
However, the existing definition is silent with respect to the 
characterization of spoil placed on the mined-out area in excess of the 
amount of spoil needed to restore the approximate original contour. We 
propose to revise the definition of excess spoil and add a definition 
of backfill to more clearly differentiate among backfill, material 
placed in excess spoil fills, and thick overburden returned to the 
mined-out area under 30 CFR 816.105.

[[Page 44471]]

    Specifically, we propose to define excess spoil as including all 
spoil material disposed of in a location other than the mined-out area 
within the permit area. The definition also would include all spoil 
material placed above the approximate original contour within the 
mined-out area as part of the continued construction of an excess spoil 
fill with a toe located outside the mined-out area. The added language 
concerning continuation of an excess spoil fill onto the mined-out area 
is intended to ensure that the fill is constructed using consistent 
standards for the entire structure so that the fill is uniformly 
stable.
    The revised definition would retain the clarification that spoil 
used to restore the approximate original contour of the mined-out area 
is not excess spoil. It also would retain the exception for spoil used 
to blend the mined-out area with the surrounding terrain in non-steep 
slope areas. We propose to add a new provision clarifying that the 
definition does not include spoil material placed within the mined-out 
area in accordance with the thick overburden provisions of 30 CFR 
816.105(b)(1), even if it exceeds the amount needed to restore the 
approximate original contour, unless that material is a continuation of 
an excess spoil fill. This provision would eliminate any ambiguity 
regarding thick overburden treatment in the existing rules and is 
consistent with the thick overburden provisions of section 515(b)(3) of 
SMCRA,\153\ which makes no reference to the excess spoil provisions of 
section 515(b)(22) of SMCRA \154\ in establishing requirements for the 
placement and grading of spoil within the mined-out area.

    \154\ 30 U.S.C. 1265(b)(22).
---------------------------------------------------------------------------

    In summary, under our proposed rule, the general backfilling and 
grading requirements of 30 CFR 816.102 or 817.102 would apply to all 
spoil placed in the mined-out area for the purpose of restoring the 
approximate original contour within the parameters of those rules. The 
thick overburden performance standards of 30 CFR 816.105(b) would apply 
to all spoil placed in or on the mined-out area in excess of the 
approximate original contour parameters established in 30 CFR 
816.102(a)(1) or 817.102(a)(1), with the exception of spoil that is a 
continuation of an excess spoil fill with a toe located outside the 
mined-out area. For all operations, the excess spoil disposal 
requirements of 30 CFR 816.71 and 816.74 or 817.71 and 817.74 would 
govern the construction of excess spoil fills, including any spoil 
placed above the approximate original contour within the mined-out area 
as part of the continuation of an excess spoil fill with a toe located 
outside the mined-out area.
Fill
    We propose to define the term ``fill'' to clarify the meaning of 
this term as it is used in the context of surface coal mining 
operations under SMCRA and to differentiate this term from the term 
``fill material'' as used and defined in the regulations implementing 
section 404 of the Clean Water Act.\155\ See 33 CFR 323.2(e) and 40 CFR 
232.2. Our proposed definition would include only permanent, non-
impounding structures constructed for the purpose of disposing of 
excess spoil and solid coal mine waste, consistent with the common 
usage of this term in the context of coal mining operations. It would 
not include any impoundments or temporary structures. It has no 
relationship to whether construction of the excess spoil or coal mine 
waste disposal facility involves the discharge of dredged or fill 
material into waters of the United States under the Clean Water Act.

Fugitive Dust
    We propose to remove this definition because it defines a term that 
we no longer use in our regulations. See the preamble discussions of 
proposed 30 CFR 780.12(f) and our proposed removal of existing 30 CFR 
780.15 and 784.26 for further explanation.
Groundwater
    This definition would replace the existing definition of the term 
``Ground water.'' We propose to replace the words ``ground water'' with 
the single word ``groundwater'' throughout our regulations for internal 
consistency. We also propose to revise the definition to add clarity 
and to more closely resemble generally-accepted definitions in 
scientific and trade publications. Specifically, our proposed 
definition is adapted from Freeze and Cherry (1979) \156\ and a 
publication entitled ``The ABCs of Aquifers.'' \157\ Under the proposed 
rule, ``groundwater'' would mean subsurface water located in those 
portions of soils and geologic formations that are completely saturated 
with water; i.e., those zones where all the pore spaces and rock 
fractures are completely filled with water. We propose to add a 
sentence clarifying that this term includes subsurface water in both 
regional and perched aquifers, but that it does not include water in 
soil horizons that are temporarily saturated by precipitation events.

    Perched aquifers occur where subsurface water collects above 
unsaturated rock formations as a result of a discontinuous impermeable 
layer.\158\ Perched aquifers are fairly common in glacial 
sediments.\159\ They also occur in other sedimentary formations where 
weathered layers, ancient soils or caliche (found in arid or semiarid 
areas) have created impermeable zones.\160\ Perched aquifers are often 
removed by surface coal mining operations; they need not be restored 
unless restoration is needed to prevent material damage to the 
hydrologic balance outside the permit area.

Highwall Remnant
    We propose to remove this definition because the term ``highwall 
remnant'' is self-explanatory and because the existing definition 
inappropriately limits the term to remining operations. There is no 
basis under SMCRA for this limitation.
Hydrologic Balance
    The existing definition of hydrologic balance mentions water 
quality, but focuses on water quantity, water flow and movement, water 
storage, and changes in the physical state of water. We propose to 
revise this definition to include provisions relating to water quality 
and the impact of water quality on the biological condition of streams. 
Specifically, we propose to add language stating that the term includes 
interactions that result in changes in the chemical composition or 
physical characteristics of groundwater and surface water, which may 
affect the biological condition of streams and other water bodies. The 
proposed revisions are intended to clarify that water quality is as 
important as water quantity. They are consistent with the manner and 
context in which the term ``hydrologic balance'' appears in SMCRA. 
Sections 507, 508, 510, 515, and 516 of SMCRA\161\ contain repeated 
references to water quality considerations. As summarized in Part II of 
this preamble, in many cases, adverse impacts on water quality and the 
resulting change in the biological condition of streams are the 
principal

area as we proposed to define that term in 30 CFR 701.5.

Intermittent Stream
    We propose to redefine ``intermittent stream'' in a manner that is 
substantively identical to the manner in which the U.S. Army Corps of 
Engineers defines that term in Part F of the 2012 reissuance of the 
nationwide permits under section 404 of the Clean Water Act. See 77 FR 
10184, 10288 (Feb. 21, 2012). Adoption of a substantively-identical 
definition would promote consistency in application and interpretation 
of that term under both SMCRA and Clean Water Act programs.
    We invite comment on whether the definition in the final rule 
should include language specifying that the U.S. Army Corps of 
Engineers has the ultimate authority to determine the point at which an 
ephemeral stream becomes an intermittent stream or a perennial stream 
and vice versa. Further, if the final rule includes language to that 
effect, we invite comment on whether the definition also should provide 
that any determination that the Corps makes concerning these transition 
points will be controlling for purposes of SMCRA regulatory programs. 
Commenters should discuss the applicability of two SMCRA provisions in 
this context. First, section 702(a) of SMCRA \162\ provides that 
``[n]othing in this Act shall be construed as superseding, amending, 
modifying, or repealing'' the Clean Water Act, any rule or regulation 
adopted under the Clean Water Act, or any state laws enacted pursuant 
to the Clean Water Act. Second, section 505(b) of SMCRA \163\ provides 
that any provision of any state law or regulation may not be construed 
to be inconsistent with SMCRA if it ``provides for more stringent land 
use and environmental controls and regulations of surface coal mining 
and reclamation operation[s] than do the provisions of this Act or any 
regulation issued pursuant thereto.'' In other words, should our 
regulations allow states to adopt and apply stream definitions in a 
manner that would protect a greater length of stream than would the 
Corps determinations?

    \162\ 30 U.S.C. 1292(a).
    \163\ 30 U.S.C. 1255(b).
---------------------------------------------------------------------------

    Our existing definition has two principal differences with the 
Corps' definition that we propose to adopt. First, paragraph (b) of our 
existing definition of an intermittent stream would not consider a 
stream with a base flow resulting from the melting of a snowpack to be 
an intermittent stream because the snowpack does not lie below the 
local water table and because snowmelt is not considered groundwater. 
However, the preamble to the definition of ``ephemeral stream'' that 
the Corps adopted as part of the 2012 reissuance of the nationwide 
permits under section 404 of the Clean Water Act states that snowmelt 
contributes to the flow of intermittent and perennial streams, 
especially in areas with deep snow packs, and that melting snow should 
not be considered a precipitation event because the development of a 
snowpack occurs over the course of a winter season. See 77 FR 10184, 
10262 (Feb. 21, 2012). In essence, the preamble discussion would allow 
a stream originating from a melting snowpack to be considered an 
intermittent stream even though the definition of ``intermittent 
stream'' requires groundwater as the source of base flow. We invite 
comment on whether we should revise our proposed definition of 
``intermittent stream'' to include language consistent with the 
discussion of snowmelt in the preamble to the Corps' definition of 
``ephemeral stream.''
    Second, we propose to remove paragraph (a) of our existing 
definition of ``intermittent stream.'' That paragraph automatically 
designates any stream or reach of a stream that drains a watershed of 
at least one square mile as an intermittent stream. This provision is 
inconsistent with generally-accepted stream classification systems 
because it is based on watershed size rather than streambed 
characteristics and duration and source of streamflow. For example, one 
study in West Virginia found perennial streams with a median drainage 
area of less than 0.1 square mile and intermittent flows with a median 
drainage area of 14.5 acres, both of which are much smaller than one 
square mile (640 acres).\164\ On the other hand, ephemeral streams in 
arid regions can have drainage areas of dozens of square miles. 
Furthermore, the existing definition could be construed as meaning that 
all streams with a watershed greater than one square mile are 
intermittent, even when they would otherwise be classified as perennial 
streams.

Hydrologic Characteristics for Headwater Streams in the Mountaintop 
Coal-Mining Region of Southern West Virginia, 2000-2001.'' Water-
Resources Investigations Report 02-4300, U.S. Department of the 
Interior Geological Survey.
---------------------------------------------------------------------------

    We originally adopted the watershed-size criterion because Alabama 
and Illinois found it easy to administer and apply and because we 
believed that a stream with a watershed of that size has a potential 
for flood volumes that would necessitate application of the stream-
channel diversion requirements.\165\ As explained below, we no longer 
find either reason compelling.
---------------------------------------------------------------------------

    \165\ 44 FR 14932 (Mar. 13, 1979).
---------------------------------------------------------------------------

    First, the easy-to-administer argument is valid only if the 
watershed-size criterion was the only criterion for determining whether 
a stream is intermittent. However, that is not the case. The existing 
definition also provides that any stream that is below the local water 
table for at least part of the year and obtains its flow from both 
surface runoff and groundwater discharge is an intermittent stream. As 
discussed above, both perennial and intermittent streams often have 
watersheds much smaller than one square mile, so the permit applicant 
and the regulatory authority still must conduct a hydrological 
evaluation of streams in watersheds smaller than one square mile to 
determine whether they are nonetheless intermittent or perennial based 
on the source of streamflow.
    With respect to the second reason, the possibility of flood damage 
from diversion of an otherwise-ephemeral stream with a watershed 
greater than one square mile does not justify retention of a definition 
of intermittent stream that is not consistent with definitions used by 
the U.S. Army Corps of Engineers and the scientific community. The 
preamble to 30 CFR 816.43 and 817.43 requests comment on whether we 
should revise our regulations governing diversions to adopt design 
requirements based on whether the diversion is permanent or temporary 
rather than on whether the flow being diverted is perennial, 
intermittent, or ephemeral.
Land Use
    We propose to revise the introductory text of this definition for 
clarity and to add a sentence specifying that the individual land use 
categories in the definition are the categories to be used in the 
regulatory program. In addition, we propose to remove the third 
sentence of the first paragraph of the existing definition. That 
sentence reads: ``Changes of land use from one of the following 
categories to another shall be considered as a change to an alternative 
land use which is subject to approval by the regulatory authority.'' 
This sentence is inconsistent with the revisions that we are proposing 
to 30 CFR 780.24 and 784.24, as discussed later in this preamble. Under 
our proposed revisions to those rules, a proposed postmining

[[Page 44473]]

land use that differs from the actual premining land use would not 
require approval as a higher or better use if the land as it existed 
before mining was already capable of supporting that use in its 
existing condition. Moreover, this change would better implement 
section 515(b)(2) of SMCRA,\166\ which provides that the permittee must 
``restore the land affected to a condition capable of supporting the 
uses [not just the use that existed immediately prior to mining] which 
it was capable of supporting prior to any mining, or higher or better 
uses of which there is reasonable likelihood.'' This statutory language 
indicates that the alternative postmining land use requirements in our 
rules should apply only when the applicant or permittee proposes a 
higher or better use, not a use that the land was capable of supporting 
before mining.
---------------------------------------------------------------------------

    \166\ 30 U.S.C. 1265(b)(2).
---------------------------------------------------------------------------

    We also propose to revise the definition of cropland in paragraph 
(a) of the definition of land use to more accurately and inclusively 
describe the types of plantings and planting settings associated with 
that land use category. Specifically, we propose to include commercial 
nursery plantings, vegetables, fruits, nuts, and other plants typically 
grown in fields, orchards, vineyards, and similar settings involving 
intensive agricultural uses.
Material Damage
    We propose to revise a cross-reference to 30 CFR 784.20 in this 
definition to be consistent with our proposed redesignation of existing 
Sec.  784.20 as Sec.  784.30. We propose no other changes to this 
definition, which applies only in the context of damage that occurs as 
a result of subsidence caused by underground mining operations. It is 
not related to, nor does it replace or supersede, the definition of 
``material damage to the hydrologic balance outside the permit area'' 
or requirements related to that definition.
Material Damage to the Hydrologic Balance Outside the Permit Area
    Our existing regulations do not define this term, which, as 
discussed below, is central to one of the principal findings required 
for approval of a permit application. Section 510(b)(3) of SMCRA \167\ 
specifies that the regulatory authority may not approve a permit 
application unless the regulatory authority has ``made an assessment of 
the probable cumulative impact of all anticipated mining in the area on 
the hydrologic balance specified in section 507(b).'' This assessment 
is generally referred to as the cumulative hydrologic impact assessment 
(CHIA). Section 507(b)(11) of SMCRA,\168\ the pertinent part of the 
SMCRA section referenced in the quote above, requires that each permit 
application include--
---------------------------------------------------------------------------

    \167\ 30 U.S.C. 1260(b)(3).
    \168\ 30 U.S.C. 1257(b)(11).

a determination of the probable hydrologic consequences of the 
mining and reclamation operations, both on and off the mine site, 
with respect to the hydrologic regime, quantity and quality of water 
in surface and ground water systems including the dissolved and 
suspended solids under seasonal flow conditions and the collection 
of sufficient data for the mine site and surrounding areas so that 
an assessment can be made by the regulatory authority of the 
probable cumulative impact of all anticipated mining in the area 
upon the hydrology of the area and particularly upon water 
---------------------------------------------------------------------------
availability.

    Section 510(b)(3) also specifies that the regulatory authority may 
not approve a permit unless the application affirmatively demonstrates 
and the regulatory authority finds in writing that the proposed 
operation ``has been designed to prevent material damage to the 
hydrologic balance outside the permit area.'' However, SMCRA does not 
define or explain the meaning of the term ``material damage to the 
hydrologic balance outside the permit area.''
    Our existing regulations do not fully integrate the implementation 
of sections 507(b)(11) and 510(b)(3) of SMCRA \169\ because they do not 
require collection of sufficient data for the proposed permit area and 
surrounding areas to prepare an adequate CHIA and because they do not 
define or establish criteria for determining material damage to the 
hydrologic balance outside the permit area. In particular, they do not 
specifically require data related to the biological community in 
streams or data comprised of a complete suite of the chemical and 
physical constituents and properties of groundwater and surface water. 
Without sound baseline information on surface-water and groundwater 
quality and quantity and the biological communities in streams, the 
regulatory authority cannot prepare an adequate cumulative hydrologic 
impact assessment or determine whether the proposed mining operation 
has been designed to prevent material damage to the hydrologic balance 
outside the permit area. This proposed rule is intended to correct this 
problem by adding a definition of the term ``material damage to the 
hydrologic balance outside the permit area'' and by refining and 
expanding baseline data requirements for permit applications, which we 
discuss later in this preamble in connection with proposed 30 CFR 
780.19. These two changes would promote more effective implementation 
of sections 507(b)(11) and 510(b)(3) of SMCRA \170\ and, in combination 
with the improved monitoring requirements in proposed 30 CFR 780.23 and 
816.35 through 816.37, would better protect streams.

    In developing a definition of ``material damage to the hydrologic 
balance outside the permit area,'' we looked to our previous statements 
on this matter in preambles to our regulations concerning hydrology and 
geology. We also examined other provisions of SMCRA and the legislative 
history of section 510(b)(3) of SMCRA.\171\ Several commenters on a 
proposed rule on hydrology and geology that we published on June 25, 
1982 (47 FR 27712), requested that we add a definition of material 
damage to the hydrologic balance outside the permit area to our 
regulations. However, the preamble to the final rule that we adopted in 
response to that proposed rule explains that we declined the requests 
for a definition ``because the gauges for measuring material damage may 
vary from area to area and from operation to operation. OSM[RE] has not 
established fixed criteria, except for those established under 
Sec. Sec.  816.42 and 817.42 related to compliance with water-quality 
standards and effluent limitations.'' \172\ The preamble provides no 
further explanation of that statement, but it does state that we agreed 
with commenters that ``regulatory authorities should establish criteria 
to measure material damage.'' \173\

---------------------------------------------------------------------------

    In the 30 years since we published that preamble, very few states 
have adopted a definition or established programmatic criteria for 
material damage to the hydrologic balance outside the permit area. 
Therefore, adoption of a federal definition of material damage to the 
hydrologic balance outside the permit area is both necessary and 
appropriate to ensure effective and consistent application of that 
term.
    In addition, the absence of either a federal definition of or 
criteria for material damage to the hydrologic balance outside the 
permit area has made it difficult for us to determine whether states 
are effectively implementing their counterparts to 30 CFR 773.15(c) and 
section 510(b)(3) of

[[Page 44474]]

SMCRA.\174\ As we have long recognized, definitions can help us more 
effectively implement SMCRA: ``Many of the terms used by Congress are 
not defined or explained and thus are too vague to be enforced 
effectively until given more precise meanings.'' \175\

    The legislative history of section 510(b)(3) of SMCRA \176\ 
provides little illumination as to the meaning of material damage to 
the hydrologic balance outside the permit area and thus is of little 
assistance in developing a definition. The term first appears in H.R. 
2, the House version of the legislation that ultimately became SMCRA. 
Earlier unsuccessful precursors to SMCRA used the phrase ``significant 
irreparable offsite damage,'' which also was undefined. In explaining 
the change in terminology, the Committee report states only that the 
previous phrase was ``deleted in favor of language that specifies that 
the mine is to be designed to prevent damage to the hydrologic balance 
outside the permit area.'' \177\ There is no discussion of whether, in 
making this substitution, Congress intended to eliminate the elements 
of ``significant'' and ``irreparable'' from the standard, or whether 
the new language is merely a nonsubstantive change in wording.

    When we declined to define ``material damage to the hydrologic 
balance outside the permit area'' in 1983, we noted that the only fixed 
criteria that we established at the time for such damage were those 
included in ``Sec. Sec.  816.42 and 817.42 related to compliance with 
water-quality standards and effluent limitations.'' However, we do not 
think it appropriate to interpret this preamble statement as meaning 
that any exceedance of water quality standards or effluent limitations, 
no matter how minor and no matter what the cause, would constitute 
material damage to the hydrologic balance outside the permit area.
    Our proposed definition reflects our conclusion that the mere 
possibility of an acid or toxic discharge or other type of degradation 
of surface water or groundwater does not provide an adequate basis for 
permit denial on the grounds that it would not prevent material damage 
to the hydrologic balance outside the permit area. Instead, for a 
permit to be denied on this basis, there must be some probability of 
the formation of acid or toxic mine drainage that may continue after 
the completion of mining and land reclamation, and there must be a 
reasonable likelihood that the reclamation plan proposed by the 
applicant will not be capable of preventing the formation of that 
drainage. We base our conclusion, in part, on our prior statements 
relating to the preparation of cumulative hydrologic impact 
assessments. We find these statements to be particularly instructive 
because section 510(b)(3) of SMCRA,\178\ which refers to those 
assessments, also contains the term ``material damage to the hydrologic 
balance outside the permit area.'' In particular, in the preamble to 
the 1983 version of 30 CFR 780.21(g), we stated that the cumulative 
hydrologic impact assessment must be ``accomplished in an 
environmentally and scientifically sound fashion,'' and that it 
``cannot reasonably be extended to include remote and speculative 
impacts.'' \179\ Instead, we determined that the assessment ``should be 
based upon those impacts that have a reasonable likelihood for 
occurring and which are sufficiently defined to enable the regulatory 
authority to reach a decision.'' \180\

Thus, we looked to other sources, including related provisions of 
SMCRA, to provide some guidance as to what material damage to the 
hydrologic balance outside the permit area means in the context of 
water quality parameters for which there are no effluent limitations. 
Section 508(a)(13) of SMCRA \181\ requires that each reclamation plan 
include--
---------------------------------------------------------------------------

    \181\ 30 U.S.C. 1258(a)(13).

[A] detailed description of the measures to be taken during the 
mining and reclamation process to assure the protection of:
    (A) the quality of surface and ground water systems, both on- 
and off-site, from adverse effects of the mining and reclamation 
process;
    (B) the rights of present users to such water; and
    (C) the quantity of surface and ground water systems, both on- 
and off-site, from adverse effects of the mining and reclamation 
process or to provide alternative sources of water where such 
protection of quantity cannot be assured[.]

    In 1979, we noted that this provision of SMCRA, along with sections 
102, 510(b)(3), and 522(a) through (d) of the Act,\182\ ``requires that 
mining not be permitted at all, if reclamation cannot be feasibly 
performed to protect water uses. Thus, to the extent that mining would 
result in unacceptable discharges of sulfates and total dissolved 
solids, the regulatory authority should not issue permits for the areas 
involved.'' \183\ As that passage from the 1979 preamble indicates, we 
have never interpreted section 508(a)(13) of SMCRA \184\ to operate as 
an absolute prohibition on mining operations that would have adverse 
effects on the hydrologic balance. In our judgment, this provision also 
does not supersede the performance standards in sections 515 and 516 of 
SMCRA,\185\ which recognize that mining may cause some adverse effects 
on surface water and groundwater, particularly within the permit area. 
See, e.g., section 515(b)(10) of SMCRA,\186\ which provides that 
surface coal mining and reclamation operations must be conducted ``to 
minimize the disturbances to the prevailing hydrologic balance at the 
mine-site and in associated offsite areas and to the quality and 
quantity of water in surface and ground water systems both during and 
after surface coal mining operations and during reclamation.'' 
Significantly, this provision of SMCRA uses the term ``minimize'' 
rather than ``prevent'' when describing the standard that surface coal 
mining and reclamation operations must meet in this context.

    With these considerations in mind, we have designed our proposed 
definition of material damage to the hydrologic balance outside the 
permit area to protect all designated uses of surface water and all 
existing and reasonably foreseeable uses of surface water and 
groundwater outside the permit area. Specifically, in relevant part, 
under our proposed definition, ``material damage to the hydrologic 
balance outside the permit area'' would mean any adverse impact from 
surface or underground mining operations on the quantity or quality of 
surface water or groundwater, or on the biological condition of a 
perennial or intermittent stream, that would preclude any designated 
surface-water use under sections 101(a) and 303(c) of the Clean Water 
Act \187\ or any existing or reasonably foreseeable use of surface 
water or groundwater outside the permit area. Our proposed definition 
is consistent with our statement in the 1979 preamble that mining 
should not be permitted at all if reclamation cannot feasibly protect 
water uses.\188\

    States have developed multimetric bioassessment protocols for use 
in determining the biological condition of streams and other surface 
waters for purposes of preparing the water quality inventory required 
under section 305(b) of the Clean Water Act. Multimetric indices 
include metrics such as species richness, complexity, and tolerance as 
well as trophic measures. They provide a quantitative comparison (often 
referred to as an index of biological or biotic integrity) of the 
ecological complexity of biological assemblages relative to a 
regionally-defined reference condition. Under proposed 30 CFR 
780.19(e)(2) and 784.19(e)(2), states would be required to establish a 
correlation between these index values and each designated use under 
sections 101(a) and 303(c) of the Clean Water Act, as well as any other 
existing or reasonably foreseeable uses. In other words, we anticipate 
that the SMCRA regulatory authority, with assistance from the 
appropriate Clean Water Act agencies, will define the range of index 
values required to support each existing, reasonably foreseeable, and 
designated use of the stream segment in question. Any change in the 
biological condition of the stream or other surface-water body, as 
documented by index scores resulting from use of the bioassessment 
protocol for monitoring purposes, that would preclude attainment or 
maintenance of an existing, reasonably foreseeable, or designated use 
of surface water would constitute material damage to the hydrologic 
balance outside the permit area if the change in scores is a result of 
the SMCRA operation. We seek comment on the effectiveness of using 
index scores from bioassessment protocols to ascertain impacts on 
existing, reasonably foreseeable, or designated uses. If you disagree 
with the use of index scores from bioassessment protocols, please 
identify a viable and scientifically-valid alternative.
    The regulations implementing the Clean Water Act define ``existing 
uses'' as ``those uses actually attained in a waterbody on or after 
November 28, 1975, whether or not they are included in the water 
quality standards.'' See 40 CFR 131.3. In the context of this proposed 
definition, we intend to interpret the term ``existing uses'' in a 
similar fashion; i.e., existing uses would be those uses in existence 
at the time of preparation of the permit application, regardless of 
whether those uses are designated uses. Alternatively, we may replace 
the term ``existing uses'' with ``premining uses'' for purposes of 
clarity. We invite comment on this topic.
    The second part of the proposed definition of ``material damage to 
the hydrologic balance outside the permit area'' provides that this 
term means any adverse impact from surface coal mining and reclamation 
operations or from underground mining activities, including any adverse 
impacts from subsidence that may occur as a result of underground 
mining activities, on the quality or quantity of surface water or 
groundwater, or on the biological condition of a perennial or 
intermittent stream, that would impact threatened or endangered 
species, or have an adverse effect on designated critical habitat, 
outside the permit area in violation of the Endangered Species Act of 
1973, 16 U.S.C. 1531 et seq. This provision is intended to ensure 
compliance with both the Endangered Species Act and the fish and 
wildlife protection provisions of sections 515(b)(24) and 516(b)(11) of 
SMCRA. We also are considering alternative language for the second part 
of the definition. That alternative would replace the phrase ``that 
would impact threatened or endangered species, or have an adverse 
effect on designated critical habitat, outside the permit area in 
violation of the Endangered Species Act of 1973, 16 U.S.C. 1531 et 
seq.'' with ``that would jeopardize the continued existence of 
threatened or endangered species, or result in the destruction or 
adverse modification of designated critical habitat, outside the permit 
area in violation of the Endangered Species Act of 1973, 16 U.S.C. 1531 
et seq.'' The second alternative would parallel the language of 
existing and proposed 30 CFR 816.97(b) and 817.97(b).
    State water quality standards and associated water quality criteria 
provide a starting point for establishment of material damage criteria 
under SMCRA for surface waters, but they are not the endpoint. SMCRA 
material damage criteria must be no less stringent than Clean Water Act 
water quality standards and criteria in all cases, but, in some 
situations, they may need to be more stringent to protect unique uses 
or to comply with the Endangered Species Act. In addition, the SMCRA 
regulatory authority may need to establish numerical material damage 
criteria for parameters of concern for which there are no numerical 
water quality standards or water quality criteria under the Clean Water 
Act.
    The Clean Water Act does not apply to groundwater, so the SMCRA 
regulatory authority would need to use best professional judgment to 
establish material damage criteria to protect existing and reasonably 
foreseeable uses of groundwater. Material damage criteria for 
groundwater also would need to take into consideration the needs of any 
threatened or endangered species.
    The proposed definition does not differentiate between permanent or 
long-term impacts and temporary or short-term impacts. Any impact that 
would preclude a designated, existing, or reasonably foreseeable use of 
surface water outside the permit area, or an existing or reasonably 
foreseeable use of groundwater outside the permit area, would 
constitute material damage to the hydrologic balance, regardless of the 
duration of the impairment. Isolated noncompliant discharges would not 
be considered material damage unless those discharges are of a 
magnitude sufficient to preclude a protected use. We invite comment on 
whether the definition should exclude temporary adverse impacts if the 
permit applicant can demonstrate that there will be no long-term 
adverse impacts after mining is completed.
    Nothing in the proposed definition is intended to supersede the 
water supply replacement provisions of sections 717 and 720 of 
SMCRA.\189\ In other words, material damage to the hydrologic balance 
outside the permit area would not exist solely because the operation 
destroys or damages protected water supplies, provided that the 
permittee replaces those supplies in accordance with applicable 
regulatory program requirements (i.e., proposed 30 CFR 816.40 or 
817.40) and the definition of ``replacement of water supply'' in 30 CFR 
701.5.
---------------------------------------------------------------------------

    \189\ 30 U.S.C. 1307 and 1309a.
---------------------------------------------------------------------------

    The definition would apply to adverse impacts from subsidence 
resulting from underground mining operations and to other adverse 
impacts resulting from underground mining operations; e.g., dewatering 
a stream by mining through a fracture zone or dewatering an aquifer or 
saturated zone that serves as a water supply for legitimate uses. It 
would not be limited to the impacts of surface mining activities or the 
impacts of activities conducted on the surface of land in connection 
with an underground coal mine. Section 510(b)(3) of SMCRA\190\ applies 
to all applications for permits or permit revisions. This provision has 
never contained an exception for impacts from underground mining 
operations or for any other type of surface coal mining operations for 
which a permit is required.

    Paragraphs (a) and (d) of section 516 of SMCRA\191\ require that 
the Secretary take into consideration the distinct difference between 
surface and underground coal mining when promulgating regulations for 
underground mining operations. However, this provision does not justify 
allowing underground mining operations or subsidence resulting from 
underground mining operations to dewater or degrade a stream to the 
extent of precluding an existing, reasonably foreseeable, or designated 
use of that stream. Doing so would hold underground mines to a lesser 
standard of environmental protection than surface mines. Nothing in the 
environmental protection purposes of SMCRA, as set forth in paragraphs 
(a), (c), (d), and (f) of section 102 of the Act,\192\ suggests or 
supports the adoption of a lesser standard for underground mines.

---------------------------------------------------------------------------

    We are aware of concerns that including impacts from subsidence in 
the definition could effectively prohibit use of the longwall mining 
method or other high-extraction methods of underground mining to 
recover a substantial proportion of coal reserves. However, application 
of this definition to the area overlying proposed underground workings 
and the area within a reasonable angle of draw from the perimeter of 
those workings would not prohibit all mining operations that would 
result in subsidence of streams. It would only prohibit mining 
operations that would result in dewatering of a stream to the extent 
that the stream would no longer be able to support existing or 
reasonably foreseeable uses or designated uses of the stream under the 
Clean Water Act and for which there are no viable measures to prevent 
this impact. Our draft regulatory impact analysis found that the 
proposed rule, including this definition, would not strand or sterilize 
any reserves; i.e., the proposed rule would not make any coal reserves 
that are technically and economically feasible to mine under baseline 
conditions unavailable for extraction.
    Underground mine operators cannot avoid application of section 
510(b)(3) of SMCRA\193\ by drawing the permit boundaries for the mine 
to include undisturbed areas that may be affected by subsidence. In 
revising the definition of ``permit area'' in 1983, we specifically 
rejected a suggestion that the definition should include all areas 
overlying underground workings. Instead, we stated that the permit area 
consists of all ``areas for which reclamation operations are planned 
and for which the performance bond can be accurately set,'' which, we 
further explain, would not include areas with subsidence potential but 
no planned disturbance.\194\ We recognize that some state regulatory 
programs may include the area overlying the proposed underground 
workings and other undisturbed areas with subsidence potential within 
their definitions of ``permit area.'' Should our proposed definition of 
material damage to the hydrologic balance outside the permit area 
become final, those states would need to specify that the prohibition 
on the approval of permit applications for operations that would result 
in material damage to the hydrologic balance outside the permit area 
applies to all lands to which that prohibition would apply under the 
federal regulations. In other words, state regulatory authorities would 
have to ensure that the prohibition would apply to all lands overlying 
the underground mine workings and to all lands within a reasonable 
angle of draw \195\ from the perimeter of those workings, if those 
lands are not otherwise disturbed by surface operations or facilities 
associated with the underground mine.

Mountaintop Removal Mining
    We propose to consolidate the descriptions of mountaintop removal 
mining operations in existing 30 CFR 785.14(b) and 824.11(a)(2) and (3) 
into a new definition in Sec.  701.5 for clarity and ease of use. This 
new definition is consistent with section 515(c)(2) of SMCRA,\196\ 
which pertains to operations that ``remove an entire coal seam or seams 
running through the upper fraction of a mountain, ridge, or hill . . . 
by removing all of the overburden and creating a level plateau or a 
gently rolling contour with no highwalls remaining, and capable of 
supporting postmining uses in accord with the requirements of this 
section.'' We anticipate that this definition also may be useful in 
correcting misconceptions about the meaning of this term and what types 
of operations it includes.

Occupied Residential Dwelling and Structures Related Thereto
    We propose to revise a cross-reference to 30 CFR 784.20 in this 
definition to be consistent with our proposed redesignation of existing 
Sec.  784.20 as Sec.  784.30. We propose no other substantive revisions 
to this definition--only a plain language revision to the last 
sentence.
Parameters of Concern
    We propose to add a definition of this term because we use this 
term extensively in our proposed rule. Under the proposed definition, 
parameters of concern would consist of those chemical or physical 
characteristics or properties of surface water or groundwater that 
could be altered by mining activities in a manner that would adversely 
impact the quality of surface water or groundwater or the biological 
condition of a stream.
Perennial Stream
    We propose to redefine ``perennial stream'' in a manner that is 
substantively identical to the manner in which the U.S. Army Corps of 
Engineers defines that term in Part F of the 2012 reissuance of the 
nationwide permits under section 404 of the Clean Water Act. See 77 FR 
10184, 10288 (Feb. 21, 2012). Adoption of a substantively identical 
definition would promote consistency in application and interpretation 
of that term under both SMCRA and Clean Water Act programs.
    We invite comment on whether the definition in the final rule 
should include language specifying that the U.S. Army Corps of 
Engineers has the ultimate authority to determine the point at which an 
ephemeral stream becomes an intermittent stream or a perennial stream 
and vice versa. Further, if the final rule includes language to that 
effect, we invite comment on whether the definition also should provide 
that any determination that the Corps makes concerning these transition 
points will be controlling for purposes of SMCRA regulatory programs. 
Commenters should discuss the applicability of two SMCRA provisions in 
this context. First, section 702(a) of SMCRA \197\ provides that 
``[n]othing in this Act shall be construed as superseding, amending, 
modifying, or repealing'' the Clean Water Act, any rule or regulation 
adopted under the Clean Water Act, or any state laws enacted pursuant 
to the Clean Water Act. Second, section 505(b) of SMCRA \198\ provides 
that any provision of any state law or regulation may not be construed 
to be inconsistent with SMCRA if it ``provides for more stringent land 
use and environmental controls and regulations of surface coal mining 
and

[[Page 44477]]

reclamation operation[s] than do the provisions of this Act or any 
regulation issued pursuant thereto.'' In other words, should our 
regulations allow states to adopt and apply stream definitions in a 
manner that would protect a greater length of stream than would the 
Corps determinations?
---------------------------------------------------------------------------

    \197\ 30 U.S.C. 1292(a).
    \198\ 30 U.S.C. 1255(b).
---------------------------------------------------------------------------

    Our existing definition has two principal differences with the 
Corps' definition that we propose to adopt. First, our existing 
definition of a perennial stream would not consider a stream with a 
base flow resulting from the melting of a snowpack to be a perennial 
stream because the snowpack does not lie below the local water table 
and because snowmelt is not considered groundwater. However, the 
preamble to the definition of ``ephemeral stream'' that the Corps 
adopted as part of the 2012 reissuance of the nationwide permits under 
section 404 of the Clean Water Act states that snowmelt contributes to 
the flow of intermittent and perennial streams, especially in areas 
with deep snow packs, and that melting snow should not be considered a 
precipitation event because the development of a snowpack occurs over 
the course of a winter season. See 77 FR 10184, 10262 (Feb. 21, 2012). 
In essence, the preamble discussion would allow a stream originating 
from a melting snowpack to be considered a perennial stream even though 
the definition of ``perennial stream'' requires groundwater as the 
source of base flow. We invite comment on whether we should revise our 
proposed definition of ``perennial stream'' to include language 
consistent with the discussion of snowmelt in the preamble to the 
Corps' definition of ``ephemeral stream.''
    Second, the Corps' definition of ``perennial stream'' refers to 
continuous flow year-round ``during a typical year.'' Our existing 
definition refers to continuous flow during all of the calendar year. 
The Corps' definition--and hence our proposed definition--reflect the 
fact that perennial streams or segments of those streams may cease 
flowing during periods of sustained below-normal precipitation. Our 
proposed adoption of the Corps' definition would have the effect of 
clarifying that those stoppages do not result in reclassification of 
the stream as intermittent.
Reclamation
    The existing definition of reclamation in 30 CFR 701.5 provides 
that this term ``means those actions taken to restore mined land as 
required by this chapter to a postmining land use approved by the 
regulatory authority.'' This definition is too narrow and does not 
fully implement SMCRA.
    First, the existing definition applies only to the mined area, not 
to the entire disturbed area. Section 102(e) of SMCRA \199\ states that 
one of the purposes of SMCRA is to ``assure that adequate procedures 
are undertaken to reclaim surface areas as contemporaneously as 
possible with the surface coal mining operations.'' Among other things, 
the definition of ``surface coal mining operations'' in section 701(28) 
of SMCRA \200\ includes all activities conducted on the surface of 
lands in connection with a surface coal mine. Those activities are not 
limited to mined areas. In addition, paragraph (B) of the definition 
includes ``the areas upon which such activities occur or where such 
activities disturb the natural land surface.'' Therefore, we propose to 
apply the definition to the entire disturbed area, rather than limiting 
it to the mined area.
---------------------------------------------------------------------------

    \199\ 30 U.S.C. 1202(e).
    \200\ 30 U.S.C. 1291(28).
---------------------------------------------------------------------------

    Second, the existing definition includes only actions taken to 
restore land to an approved postmining land use, not to all actions 
taken to restore land and water to the conditions required by the Act 
and regulatory program. Third, the existing definition implies that the 
land must be restored to an actual postmining land use when, in fact, 
section 515(b)(2) of SMCRA\201\ requires only that the land be restored 
to a condition in which it is capable of supporting the uses it was 
capable of supporting prior to any mining or, subject to certain 
restrictions, higher or better uses.
---------------------------------------------------------------------------

    \201\ 30 U.S.C. 1265(b)(2).
---------------------------------------------------------------------------

    The proposed definition corrects these deficiencies. Our proposed 
rule would define reclamation as meaning those actions taken to restore 
the mined land and associated disturbed areas to a condition in which 
the site is (1) capable of supporting the uses it was capable of 
supporting prior to any mining or any higher or better uses approved by 
the regulatory authority, and (2) meets all other requirements of the 
permit and regulatory program that pertain to restoration of the site. 
In addition, our proposed definition specifically details what 
reclamation means for sites with discharges that require treatment. For 
those sites, we propose to revise the definition to specify that the 
term also includes those actions taken or that must be taken to 
eliminate, remediate or treat those discharges, including both 
discharges from the mined area and all other discharges that are 
hydrologically connected to either the mined area or the mining 
operation, regardless of whether those discharges are located within 
the disturbed area.
    However, nothing in this proposed definition should be construed as 
meaning that the regulatory authority may approve a permit application 
for an operation that will cause, or that is likely to cause, a 
postmining discharge that requires treatment to prevent pollution. 
Doing so would violate SMCRA as explained in the acid mine drainage 
policy statement that we issued on March 31, 1997.\202\

accessed August 27, 2014).
---------------------------------------------------------------------------

Reclamation Plan
    We propose to add this definition to clarify which provisions of 
our permit application requirements are considered part of the 
reclamation plan. Section 701(21) of SMCRA \203\ defines ``reclamation 
plan'' as ``a plan submitted by an applicant for a permit under a State 
program or Federal program which sets forth a plan for reclamation of 
the proposed surface coal mining operations pursuant to section 508 [of 
SMCRA.]'' In this proposed rule, we propose to adopt a streamlined 
version of the statutory definition that complies with plain language 
principles, eliminates the unnecessary reference to state or federal 
programs, and contains adaptations needed to reflect the structure and 
organization of the regulations that correspond to the reclamation plan 
requirements of SMCRA. Specifically, the proposed rule would replace 
the reference to section 508 of SMCRA \204\ with references to 30 CFR 
parts 780, 784, and 785. Part 780 contains the rules that implement 
section 508 of SMCRA.\205\ Part 784 is the underground mining 
counterpart of part 780. Part 785 contains permit application 
requirements, including reclamation plan requirements, that apply to 
special categories of mining.

Renewable Resource Lands
    We propose to revise this definition to clarify that it includes 
recharge areas for surface waters, not just recharge areas for 
underground waters. We find no legal or technical reason to exclude 
recharge areas for lakes, ponds, and wetlands from classification as 
renewable resource lands. Section

[[Page 44478]]

522(a)(3)(C) of SMCRA \206\ uses this term in the context of 
establishing criteria for designating lands as unsuitable for certain 
types of surface coal mining operations. Specifically, it provides that 
lands are eligible for designation if surface coal mining operations 
would ``affect renewable resource lands in which such operations could 
result in a substantial loss or reduction of long-range productivity of 
water supply . . .'' This statutory provision further provides that 
those lands ``include aquifers and aquifer recharge areas,'' but it 
does not limit the scope of that provision to those areas. Many towns 
and cities depend upon surface-water reservoirs for their water supply, 
which means that paragraph (a)(3)(C) would include the watersheds of 
those reservoirs. Surface disturbances like mining that involve removal 
of vegetation can significantly impact both the quantity and quality of 
water available from those watersheds.
---------------------------------------------------------------------------

    \206\ 30 U.S.C. 1272(a)(3)(C).
---------------------------------------------------------------------------

Replacement of Water Supply
    We propose to revise this definition by moving existing paragraphs 
(a) and (b), which describe how the water supply replacement obligation 
may be satisfied, to the performance standards at 30 CFR 816.40 and 
817.40. Existing paragraphs (a) and (b) of the definition are more 
appropriately categorized as performance standards, which means that 
they should be codified as part of the performance standards in 
subchapter K, not as part of the definition of this term.
Temporary Diversion
    We propose to revise this definition in a manner that avoids using 
part of the term itself (``diversion'') as part of the definition. In 
addition, the existing definition, which includes only diversions of 
streams and overland flow, could be construed as excluding diversion 
channels used to convey surface runoff or pit water to a siltation 
structure or treatment facility. We propose to revise the definition to 
specifically include those channels.
Waters of the United States
    To promote consistency with the Clean Water Act, we propose to 
define this term as having the same meaning as the corresponding 
definition in 40 CFR 230.3(s), which is part of the Section 404(b)(1) 
Guidelines under the Clean Water Act

C. Part 773: Requirements for Permits and Permit Processing

1. Section 773.5: How must the regulatory authority coordinate the 
permitting process with requirements under other laws?
    Section 773.5 specifies that each regulatory program must provide 
for the coordination of review and issuance of SMCRA permits with 
applicable provisions of various federal laws. It implements, in part, 
section 503(a)(6) of SMCRA,\207\ which requires that each state 
regulatory program establish ``a process for coordinating the review 
and issuance of permits for surface coal mining and reclamation 
operations with any other Federal or State permit process applicable to 
the proposed operations.''
---------------------------------------------------------------------------

    \207\ 30 U.S.C. 1253(a)(6).
---------------------------------------------------------------------------

    We propose to add the Clean Water Act, 33 U.S.C. 1251 et seq., to 
the list of laws for which coordination is required under both state 
and federal regulatory programs. Almost all surface coal mining 
operations require Clean Water Act permits and both SMCRA and the Clean 
Water Act are concerned with protection of water quality, so it makes 
sense to coordinate the SMCRA and Clean Water Act permitting processes. 
Coordination of the SMCRA and Clean Water Act permitting processes also 
would assist in reducing or eliminating potential conflicts between 
SMCRA and Clean Water Act permits. That outcome would be consistent 
with section 702(a) of SMCRA,\208\ which provides that ``[n]othing in 
this Act shall be construed as superseding, amending, modifying, or 
repealing'' the Clean Water Act, any rule or regulation adopted under 
the Clean Water Act, or any state laws enacted pursuant to the Clean 
Water Act.
---------------------------------------------------------------------------

    \208\ 30 U.S.C. 1292(a).
---------------------------------------------------------------------------

    In addition, we propose to add the National Environmental Policy 
Act of 1969 (NEPA), 42 U.S.C. 4371 et seq., to the list of laws for 
which a coordination process is required under federal regulatory 
programs. There is no need or basis to apply this coordination 
requirement to state regulatory programs approved under SMCRA because 
the Departmental Manual excludes permit applications under state SMCRA 
regulatory programs from NEPA compliance. See 516 DM 13.3.
    Finally, we propose to clarify that only federal regulatory 
programs must establish a process for coordination with the National 
Historic Preservation Act of 1966 (NHPA), 54 U.S.C. 300101 et seq. This 
change is consistent with National Mining Association v. John M. 
Fowler, 324 F.3d 752 (D.C. Cir. 2003), in which the court held that 
projects licensed or permitted by state and local agencies pursuant to 
a delegation or approval by a federal agency are not federally funded 
or federally licensed undertakings for purposes of section 106 of the 
NHPA.
2. Section 773.7: How and when will the regulatory authority review and 
make a decision on a permit application?
    We propose to restructure 30 CFR 773.7(a) to improve clarity and 
eliminate a grammatical error in the existing language. There are no 
substantive revisions to this paragraph.
    We also propose to add 30 CFR 773.7(b)(2), which would list the 
factors that the regulatory authority must consider in determining what 
constitutes a reasonable time for notifying a permit applicant whether 
the application has been approved or disapproved, in whole or in part. 
The factors in proposed paragraphs (b))(2)(i) through (iv) reflect the 
factors listed in section 514(b) of SMCRA.\209\ Proposed paragraph 
(b)(2)(v) would require consideration of the time required to complete 
the interagency permitting coordination process under 30 CFR 773.5.
---------------------------------------------------------------------------

    \209\ 30 U.S.C. 1264(b).
---------------------------------------------------------------------------

    Finally, we propose to redesignate existing 30 CFR 773.7(b) as 30 
CFR 773.7(c) and revise that paragraph to specifically state that an 
applicant for the transfer, assignment, or sale of permit rights has 
the burden of proof for establishing that the application is in 
compliance with all regulatory program requirements. We propose to make 
this change because the transfer, assignment, or sale of permit rights 
is a type of permit revision, which means that an application of that 
nature is subject to section 510(a) of SMCRA.\210\ In relevant part, 
that paragraph of the Act states that the applicant for a permit or 
permit revision has the burden of establishing that the application is 
in compliance with all requirements of the applicable regulatory 
program.
---------------------------------------------------------------------------

    \210\ 30 U.S.C. 1260(a).
---------------------------------------------------------------------------

3. Section 773.15: What findings must the regulatory authority make 
before approving a permit application?
    Most of the changes that we propose to make to this section result 
from either the application of plain language principles or an effort 
to clarify the meaning and scope of the findings that the regulatory 
authority must make before approving a permit application.
    Proposed paragraph (c)(2) would clarify that the finding that the 
proposed

[[Page 44479]]

permit area is not within an area designated as unsuitable for surface 
coal mining operations under 30 CFR parts 762 and 764 or 769 applies 
only to lands that are designated as unsuitable for the type of surface 
coal mining operations that the permit applicant proposed to conduct. 
For example, lands may be designated as unsuitable only for surface 
mining, in which case the regulatory authority may approve a permit for 
an underground mine. Similarly, proposed paragraph (c)(3) would clarify 
that the finding that the proposed permit area is not within an area 
subject to the prohibitions of 30 CFR 761.11 does not apply in 
situations in which one or more of the exceptions (valid existing 
rights, the existing operation exemption, landowner consent, joint 
approval, etc.) to those prohibitions applies.
    We propose to revise the finding in paragraph (e) concerning the 
assessment of the cumulative hydrologic impacts of mining by adding 
paragraph (e)(3), which would require that the regulatory authority 
find that it has inserted into the permit criteria defining material 
damage to the hydrologic balance outside the permit area on a site-
specific basis, expressed in numerical terms for each parameter of 
concern, as required by Sec.  780.21(b) or Sec.  784.21(b). Our 
proposed revision is intended to ensure that permit-specific criteria 
are both established and readily available to the permittee, 
inspectors, and permit reviewers.
    Existing paragraph (j) provides that, before approving a permit 
application, the regulatory authority must find that the proposed 
operation is not likely to either jeopardize the continued existence of 
threatened or endangered species or result in destruction or adverse 
modification of critical habitat, as determined under the Endangered 
Species Act of 1973, 16 U.S.C. 1531 et seq. In response to discussions 
with the U.S. Fish and Wildlife Service concerning compliance with the 
Endangered Species Act, we propose to modify paragraph (j) to extend 
the finding to include species that the Secretary has proposed for 
listing as threatened or endangered.\211\ The proposed change is 
consistent with section 7(a)(4) of the Endangered Species Act, which 
provides that ``[e]ach Federal agency shall confer with the Secretary 
on any agency action which is likely to jeopardize the continued 
existence of any species proposed to be listed under section 4 or 
result in the destruction or adverse modification of critical habitat 
proposed to be designated for such species.'' It also would assist in 
implementing the fish and wildlife protection provisions of sections 
515(b)(24) and 516(b)(11) of SMCRA. The conferencing requirement of 
section 7(a)(4) of the Endangered Species Act is not the same as the 
consultation requirement for threatened and endangered species under 
section 7(a)(2) of the Endangered Species Act. Also, the U.S. Fish and 
Wildlife Service is responsible for determining allowable take of 
species listed as threatened or endangered.
---------------------------------------------------------------------------

    \211\ We will revise this provision and other proposed rules 
concerning protection of threatened and endangered species to 
include the National Marine Fisheries Service (NMFS), which is 
responsible for administration and enforcement of the Endangered 
Species Act with respect to anadromous and marine species, if we 
determine that this rulemaking may affect species under NMFS 
jurisdiction.
---------------------------------------------------------------------------

    We propose to remove existing paragraph (m), which applies to 
permits to be issued under 30 CFR 785.25 (permits containing lands 
eligible for remining). This finding is not needed because it merely 
repeats requirements already stated in 30 CFR 785.25. In addition, 
paragraph (m) is duplicative of paragraph (h), which requires a finding 
that the applicant has satisfied all applicable requirements of 30 CFR 
part 785. Removal of existing paragraph (m) would result in the 
redesignation of existing paragraph (n) as paragraph (m).
    In addition, we propose to add a new paragraph (n), which would 
require that the regulatory authority find that the applicant has 
demonstrated that the operation has been designed to prevent the 
formation of discharges that would require long-term treatment after 
mining has been completed. The regulatory authority also would be 
required to find that the applicant has demonstrated that there is no 
credible evidence that the design of the operation will not work as 
intended to prevent the formation of discharges of that nature.
    Avoiding creation of discharges that require long-term treatment 
benefits both the permittee (because the permittee would bear the cost 
of treating the discharge) and the public (because there is no risk of 
environmental damage or use of tax receipts to pay for treatment if the 
permittee defaults). Adoption of proposed paragraph (n) would 
incorporate into regulation one of the provisions of the policy 
entitled ``Hydrologic Balance Protection: Policy Goals and Objectives 
on Correcting, Preventing, and Controlling Acid/Toxic Mine Drainage'' 
\212\ that we issued on March 31, 1997. In that policy, we explain that 
approval of a permit that would result in the creation of a discharge 
requiring long-term treatment would be inconsistent with SMCRA: ``In no 
case should a permit be approved if the determination of probable 
hydrologic consequences or other reliable hydrologic analysis predicts 
the formation of a postmining pollutional discharge that would require 
continuing long-term treatment without a defined endpoint.'' \213\ The 
regulatory authority may rely upon data from similar completed mining 
operations under conditions that are representative of those found at 
the site of the proposed operation as credible evidence for this 
demonstration and finding.

---------------------------------------------------------------------------

    We explained our authority for this provision when we issued our 
policy document:

Several commenters expressed concern that OSM exceeded its statutory 
authority by focusing on section 510(b)(3) of SMCRA, which provides 
that no permit application may be approved unless the regulatory 
authority finds that the operation has been designed to prevent 
material damage to the hydrologic balance outside the permit area, 
and interpreting that section as requiring the prevention of AMD 
[acid mine drainage] formation. The commenters noted that sections 
515(b)(10) and 516(b)(9) of SMCRA refer to minimization (rather than 
prevention) of hydrologic disturbances and avoidance (rather than 
the prevention) of AMD, with the prevention of AMD formation being 
only one of the three avoidance mechanisms listed in these sections.
    Response: The minimization and avoidance provisions of sections 
515(b)(10) and 516(b)(9) of SMCRA do not negate the material damage 
prevention requirement of section 510(b)(3). Furthermore, the Act 
specifies that the provisions cited by the commenters apply only 
during mining and reclamation. OSM interprets this limitation as 
meaning that conducting operations in a manner likely to result in 
AMD production is acceptable only when AMD formation is expected to 
be a temporary phenomenon. In other words, discharge treatment is an 
appropriate means of avoiding AMD and minimizing damage to the 
hydrologic balance only when the need for treatment has a defined 
endpoint.
* * * * *
    The approach adopted in the policy statement is fully consistent 
with the Rith Energy decision in which the IBLA [Interior Board of 
Land Appeals] upheld OSM's refusal to approve a mining plan that 
sought to minimize, rather than avoid, AMD. In that case, the IBLA 
agreed with OSM that ``the statute, as properly read, requires the 
agency to minimize disturbance to the prevailing hydrologic balance 
by avoiding acid or toxic mine drainage. Minimizing the contact of 
water and toxic-producing deposits, as argued by petitioner [Rith 
Energy], is not the standard.'' 111 IBLA 249. The policy

[[Page 44480]]

statement accords with Rith Energy because it provides that 
``[p]ermits may only be approved where the operation is designed to 
ensure that off-site material damage to the hydrologic balance will 
be prevented.'' (Emphasis added.) Permittees may not plan in advance 
to allow AMD to occur and then simply mitigate the effects of the 
AMD.\214\

    \214\ Id. at 12 and 14.

    Finally, we propose to add a new required finding in paragraph (o) 
in response to discussions with the U.S. Fish and Wildlife Service 
concerning compliance with the Endangered Species Act. This finding 
would specify that, to the extent possible using the best technology 
currently available, the proposed operation has been designed to 
minimize disturbances and adverse impacts on fish, wildlife, and 
related environmental values, as identified in Sec.  779.20 or Sec.  
783.20, and to enhance those resources where practicable, as required 
under Sec.  780.16 and Sec.  784.16. The proposed language is similar 
to sections 515(b)(24) and 516(b)(11) of SMCRA \215\ and is intended to 
reinforce those statutory provisions.

4. Section 773.17: What conditions must the regulatory authority place 
on each permit issued?
    We propose to revise paragraph (c) of this section to require that 
the permittee comply with all applicable requirements of the Act rather 
than all applicable performance standards of the Act. We propose to 
make this change because the condition also requires compliance with 
the requirements of the regulatory program, which means that the 
applicable performance standards would be in the program, not the Act.
    We propose to revise paragraph (e) of this section to require that 
the permittee notify the regulatory authority and other appropriate 
state and federal regulatory agencies of any adverse impact to the 
environment or public health or safety as a result of a noncompliance 
with any term or condition of the permit. Notification would allow 
those agencies to take any necessary action to minimize the impacts of 
the noncompliance on the environment or public health or safety, 
consistent with the purpose stated in section 102(a) of SMCRA.\216\
---------------------------------------------------------------------------

    \216\ 30 U.S.C. 1202.
---------------------------------------------------------------------------

    We propose to add a new permit condition in paragraph (h) of this 
section to require that the permittee obtain all necessary 
authorizations, certifications, and permits in accordance with Clean 
Water Act requirements before conducting any activities that require 
approval or authorization under the Clean Water Act. The new condition 
would be consistent with section 702(a) of SMCRA,\217\ which provides 
that ``[n]othing in this Act shall be construed as superseding, 
amending, modifying, or repealing'' the Clean Water Act,\218\ or any 
rule or regulation adopted under the Clean Water Act, or any state laws 
enacted pursuant to the Clean Water Act. It also would be consistent 
with our efforts to enhance coordination between the SMCRA and Clean 
Water Act regulatory authorities. Permit conditions are directly 
enforceable under SMCRA. Therefore, the addition of this permit 
condition would mean that the SMCRA regulatory authority must take 
enforcement action if the permittee does not obtain all necessary Clean 
Water Act authorizations, certifications, and permits before beginning 
any activity under the SMCRA permit that also requires approval, 
authorization, or certification under the Clean Water Act.

D. Part 774: Revision; Renewal; Transfer, Assignment, or Sale of Permit 
Rights; Post-Permit Issuance Requirements.

1. Section 774.10: When must the regulatory authority review a permit?
    We propose to revise paragraphs (a)(2) and (a)(3) of this section 
to establish identical review requirements for permits for mountaintop 
removal mining operations under 30 CFR 785.14 and for permits that 
include a variance from approximate original contour restoration 
requirements under 30 CFR 785.16. This change is appropriate because 
the statutory review requirements for those types of operations in 
paragraphs (c)(6) and (e)(6) of section 515 of SMCRA \219\ are 
substantively identical. Furthermore, these reviews are one-time 
events, not recurring requirements like midterm permit reviews.
---------------------------------------------------------------------------

    \219\ 30 U.S.C. 1265(c)(6) and (e)(6).
---------------------------------------------------------------------------

    In concert with this change, we propose to move the midterm review 
requirements for permits with a variance for a delay in contemporaneous 
reclamation requirements because of combined surface and underground 
mining from paragraph (a)(2) to a new paragraph (a)(4). Creation of the 
new single-topic paragraph also is in keeping with plain language 
principles.
2. Section 774.15: How may I renew a permit?
    We propose to revise paragraph (b)(2) of this section by adding 
paragraph (b)(2)(vii), which would require that each application for 
permit renewal include an analysis of the monitoring results for 
surface water, groundwater, and the biological condition of streams and 
an evaluation of the accuracy and adequacy of the determination of the 
probable hydrologic consequences of mining (PHC determination). We also 
propose to add paragraph (b)(2)(viii), which would require that the 
renewal application include either an update of the PHC determination 
or documentation that the findings in the existing PHC determination 
are still valid. Similarly, we propose to revise paragraph (c)(1) of 
this section by adding paragraph (c)(1)(viii), which would authorize 
the regulatory authority to withhold approval of a permit renewal 
application if monitoring results or the updated PHC determination 
indicate that the finding that the regulatory authority made under 30 
CFR 773.15(e) that the operation is designed to prevent material damage 
to the hydrologic balance outside the permit area is no longer 
accurate.
    These revisions would assist the regulatory authority in ensuring 
that the operation continues to be designed and conducted to prevent 
material damage to the hydrologic balance outside the permit area. A 
narrow reading of section 510(b)(3) of SMCRA \220\ and 30 CFR 773.15(e) 
might hold that the finding concerning material damage to the 
hydrologic balance outside the permit area is required only for the 
approval of an application for a permit or permit revision. However, we 
interpret section 510(b)(3) of SMCRA more broadly. Addition of a 
requirement for an equivalent finding as a prerequisite for the 
approval of permit renewal applications is consistent with the intent 
and purpose of section 510(b)(3) of the Act.\221\
---------------------------------------------------------------------------

    \220\ 30 U.S.C. 1260(b)(3).
    \221\ 30 U.S.C. 1260(b)(3).
---------------------------------------------------------------------------

    Proposed paragraph (b)(2)(v) is substantively identical to existing 
paragraph (b)(2)(iii), with the exception that we propose to remove the 
provision requiring that the application for a permit renewal include 
any additional bond requested by the regulatory authority. This 
provision is both unnecessary and out of sequence because, at the time 
that the permittee submits the application for renewal, the amount of 
additional bond needed, if any, would not yet be known. The regulatory 
authority determines the amount of additional bond required after 
completing a technical review of the renewal application. Proposed 
paragraph (c)(1)(vi), like existing paragraph (c)(1)(v), provides that 
the

[[Page 44481]]

regulatory authority may deny a permit renewal application if the 
applicant has not submitted the additional bond required by the 
regulatory authority. This paragraph provides sufficient protection 
against renewal of a permit that lacks the necessary bond coverage.
    We propose to revise paragraph (c)(1)(ii) to specify that the 
regulatory authority will apply the permit eligibility standards in 30 
CFR 773.12 through 773.14 in making this determination. In other words, 
applicants for permit renewal may avail themselves of the 
provisionally-issued permit procedures of 30 CFR 773.14 and the 
exception in 30 CFR 773.13 for unanticipated events or conditions at 
remining sites. Extending the exception for unanticipated events or 
conditions at remining sites to permit renewals is consistent with the 
intent of Congress in enacting section 510(e) of SMCRA.\222\
---------------------------------------------------------------------------

    \222\ 30 U.S.C. 1260(e).
---------------------------------------------------------------------------

    In addition, as a matter of equitable treatment, a permittee with a 
violation who is seeking renewal of a permit should have the same 
opportunity to obtain a provisionally-renewed permit as a person with a 
violation who is seeking to obtain a new permit has to obtain a 
provisionally-issued permit. Under 30 CFR 773.14, the regulatory 
authority may provisionally issue a permit if (1) the applicant 
certifies that each outstanding violation is being abated to the 
satisfaction of the agency with jurisdiction over the violation and the 
regulatory authority has no evidence to the contrary, (2) the applicant 
and operations owned or controlled by the applicant are in compliance 
with any abatement plan approved by the agency with jurisdiction over 
the violation, (3) the applicant is pursuing a good faith challenge to 
the pertinent ownership or control listing and there is no initial 
judicial decision in force affirming the listing, or (4) the violation 
is the subject of a good faith administrative or judicial appeal 
contesting the validity of the violation and there is no initial 
judicial decision in force affirming the violation. Our proposed 
revisions to 30 CFR 774.15(c)(1)(ii) would apply the same principles 
and criteria to the permit renewal process. In addition, the provisions 
of 30 CFR 773.14(c), which specify the actions that the regulatory 
authority must take to suspend or revoke the permit if the permittee 
ceases to be eligible for a provisionally-issued permit, would apply.
    We also propose assorted other nonsubstantive changes to 30 CFR 
774.15 to improve compliance with plain language principles.

E. Part 777: General Content Requirements for Permit Applications

1. Section 777.11: What are the format and content requirements for 
permit applications?
    We propose to revise paragraph (a)(3) of this section to require 
that permit applications be filed in an electronic format prescribed by 
the regulatory authority, unless the regulatory authority grants an 
exception to this requirement for good cause. We propose this change to 
facilitate public participation and interagency coordination in the 
permitting process because it is much more efficient and convenient to 
review and exchange information online or by email than it is to review 
hard copies, which are time-consuming to produce and which may involve 
considerable travel to other offices to review documents that cannot be 
copied. Electronic filing also would assist in the coordination of 
regulatory and inspection activities required by section 713 of 
SMCRA.\223\ Furthermore, use of an electronic format for the permitting 
process can improve efficiency by enabling correction letters and 
applicant responses to occur in real time with less expense to the 
regulatory authority and the applicant. Finally, electronic filing 
promotes attainment of the goals of the Paperwork Reduction Act.
---------------------------------------------------------------------------

    \223\ 30 U.S.C. 1303.
---------------------------------------------------------------------------

2. Section 777.13: What requirements apply to the collection, analysis, 
and reporting of technical data and to the use of models?
    We propose to consolidate existing paragraphs (a) and (b) into 
proposed paragraph (a) because both paragraphs pertain to technical 
data and analyses. Existing paragraph (a) would be recodified as 
paragraph (a)(1) and existing paragraph (b) would be recodified as 
paragraph (a)(2).
    Proposed paragraph (a)(1) would add a requirement for submission of 
metadata, which consists of data describing the contents and context of 
data files. The availability of metadata greatly increases the 
usefulness of the original data by providing information about how, 
where, when, and by whom the data were collected and analyzed. It 
enables reviewers to evaluate the validity of both the data itself and 
comparisons with data collected at other times and other places by 
other persons. Existing paragraph (a) already required submission of 
much of this information, i.e., the names of persons or organizations 
that collected and analyzed the data, the dates that the data were 
collected and analyzed, and descriptions of the methodology used to 
collect and analyze the data. We also propose to revise the rule to add 
requirements for submission of the field sampling sheets prepared for 
water samples collected from wells (the sheets would identify the 
presence of any well screens as well as the depth at which the sample 
was taken). For all samples that require laboratory analysis, the 
proposed rule would require information pertaining to the quality 
assurance and quality control procedures used by the laboratory that 
analyzed the sample. For electronic data, the proposed rule would 
require identification of any transformations that the data underwent. 
The proposed rule would not limit metadata to the specific items listed 
in proposed paragraph (a)(1). Although not specified in the proposed 
rule, metadata should be generated in a format commonly used by the 
scientific community.
    Proposed paragraph (b) would require that all sampling and analyses 
of groundwater and surface water performed to meet the permitting 
requirements of subchapter G of our regulations be conducted according 
to the methodology in 40 CFR parts 136 and 434. Proposed paragraph 
corresponds to the provisions concerning water-quality sampling and 
analysis methodologies in existing 30 CFR 780.21(a) and 784.14(a). 
Moving this provision to 30 CFR 777.13 would consolidate the 
requirements concerning sampling and analysis methodologies for 
groundwater and surface water in one location and expand their 
applicability to all pertinent data and analyses required for permit 
applications under subchapter G, which should promote better data 
collection and analysis procedures and, hence, improved permitting 
decisions.
    We propose to eliminate the incorporation by reference of the 15th 
edition of the ``Standard Methods for the Examination of Water and 
Wastewater'' in existing 30 CFR 780.21(a) and 784.14(a). That document 
is now obsolete because the current edition is the 22nd edition, which 
was published in 2012. However, rather than incorporating the current 
edition of the ``Standard Methods for the Examination of Water and 
Wastewater,'' we propose to remove the existing incorporation by 
reference of the 15th edition of that document while retaining the 
provision in the existing rule that allows use of the sampling and 
analysis methodologies in 40 CFR parts 136 and 434. This proposed 
change would ensure that sampling and analysis methodologies under 
SMCRA are

[[Page 44482]]

consistent with those approved by EPA for use for Clean Water Act 
purposes. We invite comment on whether there are any unique SMCRA-
related requirements that would necessitate incorporating the current 
edition of the ``Standard Methods for the Examination of Water and 
Wastewater'' into our rule. In other words, would the collection and 
analysis of the baseline and monitoring data that we propose to require 
under this rule involve the use of sampling and analysis methodologies 
that 40 CFR parts 136 and 434 do not include?
    Proposed paragraph (c) would require that all geological sampling 
and analyses performed to meet the permitting requirements of 
subchapter G of our regulations be conducted using a scientifically-
valid methodology. This new provision should promote better geologic 
data collection and analysis procedures and, hence, improved permitting 
decisions. Scientifically-valid methodologies include, but are not 
limited to, those set forth in the Engineering Geology Field Manual, 
Second Edition (1998), developed by the Bureau of Reclamation within 
the U.S. Department of the Interior.
    We propose to move the provisions concerning the use of models 
found in existing 30 CFR 780.21(d) and 784.14(d) to 30 CFR 777.13(d) to 
consolidate requirements concerning the use of models in the latter 
paragraph. If adopted as final, proposed paragraph (d) would apply to 
all permit application requirements. The existing provisions in 30 CFR 
780.21(d) and 784.14(d) apply only to hydrologic data, but we find no 
scientific reason for limiting the use of modeling in this manner. We 
also propose to modify the existing provisions by adding paragraph 
(d)(2), which would require that all models be calibrated using actual 
site-specific data and that they be validated for the region and 
ecosystem in which they will be used. The additional requirements are 
intended to improve the accuracy and validity of any models used. 
Finally, we propose to add a new paragraph (d)(3) clarifying that the 
regulatory authority has the discretionary authority to prohibit the 
use of models and to require the submission of additional actual, site-
specific data.
3. Section 777.15: What information must my application include to be 
administratively complete?
    We propose to revise this section to use terminology consistent 
with the revisions to the permitting regulations published on September 
28, 1983 (48 FR 44344), which removed the term ``complete application'' 
and replaced it with the terms ``administratively complete 
application'' and ``complete and accurate application.''

F. Part 779: Surface Mining Permit Applications--Minimum Requirements 
for Information on Environmental Resources and Conditions

1. Section 779.1: What does this part do?
    Existing 30 CFR 779.1 states that part 779 establishes the minimum 
requirements for the Secretary's approval of regulatory program 
provisions for the environmental resources contents of permit 
applications for surface mining activities. However, the content 
requirements and standards for approval of state regulatory programs 
are located in 30 CFR parts 730 through 732. Therefore, we propose to 
revise 30 CFR 779.1 to specify that part 779 sets forth permit 
application requirements relating to environmental resources and 
conditions.
2. Section 779.2: What is the objective of this part?
    We propose to revise this section to reflect plain language 
principles and to clarify that the objective of part 779 is to ensure 
that the permit applicant provides the regulatory authority with a 
complete and accurate description of both the environmental resources 
that may be impacted or affected by proposed surface mining activities 
and the environmental conditions that exist within the proposed permit 
and adjacent areas. The existing language does not mention 
environmental conditions, such as the information on climate required 
by 30 CFR 779.18.
3. Why are we proposing to remove existing 30 CFR 779.11 and 779.12?
    We propose to remove 30 CFR 779.11, which requires a description of 
the existing premining environmental resources within the proposed 
permit and adjacent areas, because the requirements for this 
description are set out in detail in other sections of part 779. 
Therefore, existing 30 CFR 779.11 is redundant and unnecessary.
    We propose to remove existing 30 CFR 779.12(a) because the 
anticipated mining schedule that it requires is duplicative of proposed 
30 CFR 779.24(a)(3). We propose to move the cultural resource 
requirements of existing 30 CFR 779.12(b) to a new 30 CFR 779.17 
devoted to that topic.
4. Section 779.19: What information on vegetation must I include in my 
permit application?
    We propose to revise existing 30 CFR 779.19 by adding more 
specificity and making submission of vegetation information mandatory 
rather than discretionary as under the existing rules. The changes that 
we propose are needed to ensure that native plant communities are 
restored on reclaimed areas as required by section 515(b)(19) of 
SMCRA.\224\ Further, these changes are intended to implement, in part, 
section 515(b)(24) of SMCRA,\225\ which requires that, ``to the extent 
possible using the best technology currently available,'' surface coal 
mining and reclamation operations be conducted in a manner that will 
``minimize disturbances and adverse impacts on fish, wildlife, and 
related environmental values, and achieve enhancement of such resources 
where practicable.''

    Restoration or establishment of native plant communities is the 
most effective way of restoring or enhancing wildlife habitat. The 
Virginia Department of Conservation and Natural Resources describes the 
benefits of native plants as follows:

    The benefit of growing plants within the region they evolved is 
they are more likely to thrive under the local conditions while 
being less likely to invade new habitats. Native plants are well 
adapted to local environmental conditions, maintain or improve soil 
fertility, reduce erosion, and often require less fertilizer and 
pesticides than many alien plants. These characteristics save time 
and money and reduce the amount of harmful run-off threatening the 
aquatic resources of our streams, rivers, and estuaries. In 
addition, functionally healthy and established natural communities 
are better able to resist invasions by alien plant species. So the 
use of native plants can help prevent the spread of alien species 
already present in a region and help avert future introductions. ***
    Native plants provide familiar sources of food and shelter for 
wildlife. As natural habitats are replaced by urban and suburban 
development, the use of native plants in landscaping can provide 
essential shelter for displaced wildlife. Land managers can use 
native plants to maintain and restore wildlife habitat. Native 
wildlife species comprise a majority of the game and non-game 
animals we manage habitat for, and they evolved with native plant 
species. Although alien species are often promoted for their value 
as wildlife food plants, there is no evidence that alien plant 
materials are superior to native plants. For instance, on land 
managed for upland game animals, native warm season grasses (big and 
little bluestem, switch grass, Indian grass, coastal panic grass, 
gama grass), and other native forbs (butterfly weed, ironweed,

[[Page 44483]]

Joe Pye weed) offer good sources of nutrition without the ecological 
threats associated with nonnative forage plants. Dramatic increases 
in nesting success of both game birds and songbirds have been 
observed in fields planted with native grasses, which also offer 
superior winter cover. In addition, warm season grasses provide 
productive and palatable livestock forage. ***
    On a broader ecological scale, planting native species 
contributes to the overall health of natural communities. 
Disturbances of intact ecosystems that open and fragment habitat, 
such as land clearing activities, increase the potential of invasion 
by alien species. Native plants provide important alternatives to 
alien species for conservation and restoration projects in these 
disturbed areas. They can fill many land management needs currently 
occupied by nonnative species, and often with lower costs and 
maintenance requirements. Once established in an appropriate area, 
most native plant species are hardy and do not require watering, 
fertilizers, or pesticides.\226\

    A U.S. Fish and Wildlife Service publication describes the benefits 
---------------------------------------------------------------------------
of native plants as follows:

    Native plants naturally occur in the region in which they 
evolved. While non-native plants might provide some of the above 
benefits, native plants have many additional advantages. Because 
native plants are adapted to local soils and climate conditions, 
they generally require less watering and fertilizing than non-
natives. Natives are often more resistant to insects and disease as 
well, and so are less likely to need pesticides. Wildlife evolved 
with plants; therefore, they use native plant communities for food, 
cover and rearing young. Using native plants helps preserve the 
balance and beauty of natural ecosystems.\227\

Landscaping: Chesapeake Bay Watershed.'' U.S. Fish and Wildlife

    Notwithstanding the advantages of native plant communities, many 
regraded and revegetated areas do not contain a diverse, effective, 
permanent vegetative cover of the same seasonal variety native to the 
area as required by section 515(b)(19) of SMCRA.\228\ Instead, areas 
that were previously forested were backfilled, regraded, and 
revegetated in a manner that makes the land incapable of achieving its 
premining forested status. Those lands are now heavily compacted 
grasslands with scrub trees. Neither grassland nor the trees are 
representative of the native premining vegetation. A 2007 study 
estimates that Appalachia alone contains between 750,000 and 1.5 
million acres of such reclaimed mine land.\229\ Our proposed 
refinements to the regulations would lead to better implementation of 
the revegetation requirements of section 515(b)(19) of SMCRA.\230\ In 
addition, the proposed rule would assist in the implementation of 
section 508(a)(2) of SMCRA,\231\ which requires that the reclamation 
plan in each permit application identify both the premining land uses 
and the capability of the land prior to any mining to support a variety 
of uses.

    Moreover, the proposed rule is consistent with Section 2.(a)(2)(iv)

``[e]ach Federal agency whose actions may affect the status of invasive 
species shall, to the extent practicable and permitted by law, . . .

    Proposed paragraph (a) would require that the permit application 
identify, describe, and map existing vegetation and plant communities, 
as well as those plant communities that would exist under conditions of 
natural succession. The description and map must be adequate to 
evaluate whether the vegetation provides important habitat for fish and 
wildlife and whether the site contains any native plant communities of 
local or regional significance.
    Proposed paragraph (b) would require that the applicant adhere to 
the classifications in the National Vegetation Classification Standard 
(NVCS) \233\ in preparing the description required under proposed 
paragraph (a). The NVCS is the standard endorsed by the Federal 
Geographic Data Committee.\234\ Use of this standard would promote 
consistent identification of plant communities and development of 
appropriate revegetation plans to restore those communities following 
mining.

    Proposed paragraph (c) would allow the regulatory authority to 
approve the use of other generally-accepted vegetation classification 
systems in lieu of the NVCS. We invite comment on what other systems 
may exist.
    Proposed paragraph (d) would require that the application include a 
discussion of the potential for reestablishing the plant communities 
described in paragraph (a) after the completion of mining. This 
discussion would assist the regulatory authority in evaluating the 
proposed revegetation plan and in determining which plant communities 
the permittee must reestablish.
5. Section 779.20: What information on fish and wildlife resources must 
I include in my permit application?
    The fish and wildlife resource information requirements in existing 
30 CFR 780.16(a) identify the baseline fish and wildlife resource 
information that each permit application must include. Therefore, we 
propose to move it to part 779, which contains environmental resource 
information requirements for permit applications. Part 779 is a better 
fit for a fish and wildlife resource information requirement than part 
780, which contains operation and reclamation plan requirements. The 
fish and wildlife information requirements in existing 30 CFR 780.16(a) 
and proposed 30 CFR 779.20 are necessary to fully implement the fish 
and wildlife protection and enhancement requirements of section 
515(b)(24) of SMCRA.\235\
---------------------------------------------------------------------------

    \235\ 30 U.S.C. 1265(b)(24).
---------------------------------------------------------------------------

    Proposed paragraph (c)(1) is similar to the portion of existing 30 
CFR 780.16(a)(2)(i) that pertains to species listed or proposed for 
listing as threatened or endangered under the Endangered Species Act of 
1973, 16 U.S.C. 1531 et seq., and to critical habitat designated under 
that law. We propose to add a requirement that the site-specific 
resource information include a description of the effects of future 
state or private activities that are reasonably certain to occur within 
the proposed permit and adjacent areas. The requested information will 
assist the U.S. Fish and Wildlife Service in fulfilling its 
responsibilities under the coordination process pertaining to 
threatened or endangered species.
    Proposed paragraph (c)(2) is substantively identical to the portion 
of existing 30 CFR 780.16(a)(2)(i) that pertains to species or habitat 
protected by state statutes similar to the Endangered Species Act.
    In proposed paragraph (c)(3), which corresponds to existing 30 CFR 
780.16(a)(2)(ii), we propose to expand the list of examples of habitat 
of unusually high value to fish and

[[Page 44484]]

wildlife to include areas that support populations of endemic species 
that are vulnerable because of restricted ranges, limited mobility, 
limited reproductive capacity, or specialized habitat requirements. We 
propose to delete the reference to important streams in the existing 
regulation because proposed paragraph (c)(5) would require site-
specific information for all perennial and intermittent streams, not 
just important streams.
    Proposed paragraph (c)(4) is substantively identical to existing 30 
CFR 780.16(a)(2)(iii), except for the addition of language clarifying 
that this provision includes species identified as sensitive by a state 
or federal agency. Proposed paragraph (c)(6) would require submission 
of site-specific information when native plant communities of local or 
regional ecological significance are present.
    Proposed paragraph (d) includes the U.S. Fish and Wildlife Service 
permit application review provisions found at 30 CFR 780.16(c) in our 
existing rules. We propose to revise those provisions in response to 
discussions with the U.S. Fish and Wildlife Service concerning 
compliance with the Endangered Species Act. We will further revise this 
provision and other proposed rules concerning protection of threatened 
and endangered species to include the National Marine Fisheries Service 
(NMFS), which is responsible for administration and enforcement of the 
Endangered Species Act with respect to anadromous and marine species, 
if we determine that this rulemaking may affect species under NMFS 
jurisdiction.
    Proposed paragraph (d)(1)(i) would require that the regulatory 
authority provide the fish and wildlife resource information included 
in the permit application under proposed paragraph (c) to the 
applicable regional or field office of the U.S. Fish and Wildlife 
Service whenever that information includes species listed as threatened 
or endangered under the Endangered Species Act, critical habitat 
designated under that law, or species proposed for listing as 
threatened or endangered under that law. The proposed rule would 
require that the regulatory authority provide this information to the 
Service no later than the time that it provides written notice of 
receipt of an administratively complete permit application to the 
Service under Sec.  773.6(a)(3)(ii). Under the existing rule, the 
Service must request this information from the regulatory authority 
rather than receiving it automatically.
    Proposed paragraph (d)(1)(ii) is similar to the existing rule in 
that it allows the Service to request fish and wildlife resource 
information submitted as part of permit applications even when the 
information in those applications does not include species listed as 
threatened or endangered under the Endangered Species Act, critical 
habitat designated under that law, or species proposed for listing as 
threatened or endangered under that law. Under both the existing and 
proposed rules, the regulatory authority must provide that information 
to the Service within 10 days of receipt of the request.
    Proposed paragraph (d)(2) specifies how the regulatory authority 
must handle comments received from the Service and how any 
disagreements are to be resolved. This proposed paragraph generally 
parallels the provisions that we and the Service agreed to as a result 
of a formal section 7(a)(2) Endangered Species Act consultation 
pertaining to the approval and conduct of surface coal mining and 
reclamation operations under a SMCRA regulatory program. Specifically, 
proposed paragraphs (d)(2)(i) through (iii) provide that if the 
regulatory authority does not agree with a Service recommendation that 
pertains to fish and wildlife or plants listed as threatened or 
endangered under the Endangered Species Act or to critical habitat 
designated under that law, the regulatory authority must explain the 
rationale for that decision in a comment disposition document and must 
provide a copy of that document to the pertinent Service field office. 
The proposed rule also would require that the regulatory authority 
provide a copy of that document to the appropriate OSMRE field office 
for informational purposes and to allow the OSMRE field office to 
monitor resolution of the disagreement. If the Service field office 
does not concur with the regulatory authority's decision and the 
regulatory authority and the Service field office are subsequently 
unable to conclude an agreement at that level, the proposed rule allows 
either the regulatory authority or the Service to elevate the issue 
through the chain of command of the regulatory authority, the Service, 
and OSMRE for resolution.
    Proposed paragraph (d)(2)(iv) provides that the regulatory 
authority may not approve the permit application until all issues are 
resolved in accordance with this process and the regulatory authority 
receives written documentation from the Service that all issues have 
been resolved. Like all provisions in proposed paragraph (d)(2), this 
provision is intended to ensure the protection of threatened and 
endangered species in accordance with the Endangered Species Act.
    Proposed paragraph (e) provides that the regulatory authority may 
require the prevention of adverse impacts to streams and watersheds in 
the permit and adjacent areas in order to protect exceptional 
environmental values. The proposed rule would require that all 
decisions be based upon scientific principles and analyses. In 
addition, it would require coordination with state and federal fish and 
wildlife agencies and agencies responsible for implementing the Clean 
Water Act before taking action under this paragraph. The protection 
that this proposed rule would provide through the permitting process 
would be in addition to any protection that might be available through 
the process for designating lands as unsuitable for surface coal mining 
operations under section 522 of SMCRA.\236\ The proposed rule is 
consistent with section 102(c) of SMCRA,\237\ which provides that one 
of the purposes of the Act is to ``assure that surface mining 
operations are not conducted where reclamation as required by this Act 
is not feasible.'' Section 515(b)(23) of SMCRA,\238\ requires that 
surface coal mining and reclamation operations ``meet such other 
criteria as are necessary to achieve reclamation in accordance with the 
purposes of this Act, taking into consideration the physical, 
climatological, and other characteristics of the site.'' The site-
specific nature of our proposed rule is consistent with this provision 
of the Act.

6. Section 779.21: What information on soils must I include in my 
permit application?
    Existing 30 CFR 779.21 requires that each permit applicant submit 
adequate soil survey information for the proposed permit area. On 
August 4, 1980, we suspended the existing rules insofar as they apply 
to lands other than prime farmland.\239\ The suspension reflects the 
February 26, 1980, decision of the U.S. District Court for the District 
of Columbia in litigation concerning the permanent regulatory program 
rules that we adopted in 1979. In that decision, the court held that 
section 507(b)(16) of SMCRA \240\ is a clear expression of 
congressional intent to require soil surveys only for prime farmlands 
identified by a reconnaissance inspection. The court also ruled that 
the

justification for the rule was misplaced.\242\

---------------------------------------------------------------------------

    We propose to lift the suspension of existing 30 CFR 779.21 and 
replace the provisions of the existing rule with revised rule text that 
is consistent with the court decision. Proposed paragraph (a) would 
require that the application include the results of a reconnaissance 
inspection of the proposed permit area to determine whether or not 
prime farmland is present, as required by 30 CFR 785.17(b)(1). If that 
inspection indicates that prime farmland may be present, proposed 
paragraph (e) would require that the application include the soil 
survey information required by 30 CFR 785.17(b)(3). Proposed paragraphs 
(a) and (e) do not contain any new requirements; they merely include 
and cross-reference existing prime farmland regulations.
    Proposed paragraph (b) would require a map showing all soil mapping 
units located within the proposed permit area, if the National 
Cooperative Soil Survey (NCSS) has completed and published a soil 
survey for the area. The application also would be required to include 
either a link to the appropriate soil survey information on the Natural 
Resources Conservation Service (NRCS) Web site, which is located at 
https://websoilsurvey.sc.egov.usda.gov/App/HomePage.htm (as of August 
27, 2014), or the equivalent information in paper form.
    Proposed paragraph (c) would require a description of soil depths 
within the proposed permit area. Proposed paragraph (d) would require 
detailed information on soil quality to satisfy the requirements of 
proposed 30 CFR 780.12(e)(2)(ii) if the permit applicant seeks approval 
for the use of soil substitutes or supplements under 30 CFR 780.12(e). 
Proposed paragraph (e) is discussed above together with proposed 
paragraph (a). Proposed paragraph (f) would require that the permit 
applicant provide any other information that the regulatory authority 
finds necessary to determine land use capability and to prepare the 
reclamation plan.
    The revised version of 30 CFR 779.21 that we are proposing today 
would be consistent with the decision in PSMRL I, Round I. First, the 
proposed rule would not require that the applicant conduct an actual 
soil survey for lands other than prime farmland. Instead, it would 
require submission of only existing soil survey information, which, 
apart from transferring pertinent information to the permit application 
maps, can be provided by reference to the appropriate link to the NRCS 
Web site. The proposed rule would not require that the applicant 
conduct an actual soil survey if the information is not available from 
the NRCS. (The NRCS has completed soil surveys for more than 99 percent 
of the land area within the conterminous states.)
    Second, the statutory basis for proposed 30 CFR 779.21 is section 
508(a)(2) of SMCRA,\243\ not section 508(a)(3).\244\ The court held 
that section 508(a)(3) did not constitute authority for the prior rule. 
However, section 508(a)(2) provides that--
---------------------------------------------------------------------------

    \243\ 30 U.S.C. 1258(a)(2).
    \244\ 30 U.S.C. 1258(a)(3).

Each reclamation plan submitted as part of a permit application 
pursuant to any approved State program or a Federal program under 
the provisions of this Act shall include, in the degree of detail 
necessary to demonstrate that reclamation required by the State or 
Federal program can be accomplished, a statement of:
* * * * *
    (B) the capability of the land prior to any mining to support a 
variety of uses giving consideration to soil and foundation 
characteristics, topography, and vegetative cover, and, if 
applicable, a soil survey prepared pursuant to section 507(b)(16).

    All the information that we propose to require in 30 CFR 779.21 
consists of soil and foundation characteristics. Section 508(a)(2) of 
SMCRA \245\ requires the applicant to include that information in each 
permit application, not just in those applications that contain prime 
farmland. Identification of soil mapping units and submission of 
available soil survey information about those units, as proposed 
paragraph (b) would require, is critical to determining the premining 
capability of the land, as required by section 508(a)(2)(B) of 
SMCRA,\246\ and to establishing the soil salvage and replacement 
requirements needed to ensure that the revegetation requirements of the 
Act and regulations can be met.
---------------------------------------------------------------------------

    \245\ 30 U.S.C. 1258(a)(2).
    \246\ 30 U.S.C. 1258(a)(2)(B).
---------------------------------------------------------------------------

    Likewise, the premining soil depth, soil quality, and other 
information that would be required under proposed paragraphs (c), (d), 
and (f) also is needed for the applicant and the regulatory authority 
to effectively determine the premining capability of the land and to 
establish the soil salvage, soil substitute, and soil replacement 
requirements needed to ensure that the revegetation requirements of the 
Act and regulations can be met. Furthermore, soil depth and quality are 
critical to determining the productivity of the site and hence to 
establishing pertinent revegetation success standards for the site for 
certain postmining land uses.
7. Section 779.22: What information on land use and productivity must I 
include in my permit application?
    The counterpart in our existing rules to this section is 30 CFR 
780.23(a). We propose to delete the second sentence of existing 
paragraph (a)(1), which provides that the application must include a 
description of the historical use of the land if the premining use 
changed within the 5 years preceding the anticipated starting date of 
the proposed operation. SMCRA does not include a similar provision and 
this timeframe has sometimes proven difficult to determine with 
precision. Furthermore, this information has little or no value in the 
existing permitting process because it is not a criterion or 
determinant of any permitting decisions under the existing rules.
    The proposed rule would continue to require that the application 
include a narrative analysis of the capability of the land before any 
mining to support a variety of uses, as required by section 
508(a)(2)(B) of SMCRA.\247\ We propose to require a description of all 
historical uses of the land without a time limitation and without 
limitation to the single use preceding the permit application, as a 
component of this narrative because historical uses provide 
documentation, in part, of premining land use capability. Our proposed 
revisions are consistent with the legislative history of this provision 
of SMCRA, which states that:
---------------------------------------------------------------------------

    \247\ 30 U.S.C. 1258(a)(2)(B).

The description is to serve as a benchmark against which the 
adequacy of reclamation and the degradation resulting from the 
proposed mining may be measured. It is important that the potential 
utility which the land had for a variety of uses be the benchmark 
rather than any single, possibly low value, use which by 
circumstances may have existed at the time mining began.\248\
---------------------------------------------------------------------------

    \248\ S. Rep. No. 95-128, at 76-77 (1977).

    Thus, it is clear that a single-use criterion is not in accordance 
with sections 508(a) and 515(b)(2) of SMCRA \249\ or the legislative 
history of section 508(a). The postmining land use must be compared 
with the variety of uses that the land was capable of supporting before 
any mining, not just a single premining use.
---------------------------------------------------------------------------

    \249\ 30 U.S.C. 1258(a) and 1265(b)(2), respectively.
---------------------------------------------------------------------------

    We also propose to add paragraph (b)(3), which would require that 
the permit application include a narrative

[[Page 44486]]

analysis of the premining productivity of the proposed permit area for 
fish and wildlife. Section 508(a)(2)(C) of SMCRA \250\ lists 
productivity in terms of the average yield of food, fiber, forage, or 
wood products, but it is not an exclusive list of productivity measures 
that can be used to assess premining productivity. The fish and 
wildlife information required by proposed paragraph (b)(3) would assist 
the regulatory authority in evaluating the environmental impacts of the 
proposed operation and in determining what fish and wildlife protection 
and enhancement measures may be appropriate. Limiting productivity 
measures to quantifiable commodity indicators such as food, fiber, and 
wood products would incorrectly ignore the underlying purposes of 
SMCRA, one of which is to establish a nationwide program to protect 
society and the environment from the adverse effects of surface coal 
mining operations.\251\
---------------------------------------------------------------------------

    \250\ 30 U.S.C. 1258(a)(2)(C).
    \251\ See 30 U.S.C. 1202(a).
---------------------------------------------------------------------------

    Following the same logic, we propose to add paragraph (c), which 
would allow the regulatory authority to require submission of any 
additional information that the regulatory authority deems necessary to 
determine the condition, capability, and productivity of the land 
within the proposed permit area. This additional information may 
include data concerning the site's carbon absorption and storage 
capability.
8. Section 779.24: What maps, plans, and cross-sections must I submit 
with my permit application?
    We propose to consolidate existing 30 CFR 779.24 and 779.25 into 30 
CFR 779.24 and add a new paragraph (c) to clarify that the regulatory 
authority may require that the applicant submit all materials in a 
digital format that includes all necessary metadata. We invite comment 
on whether the digital format option should instead be mandatory to 
facilitate review by both the public and the regulatory authority.
    Other substantive proposed changes are discussed below.
    Proposed paragraph (a)(3) would require a description of the size, 
sequence, and timing of the mining of subareas for which the applicant 
anticipates seeking additional permits or expansion of an existing 
permit in the future. The corresponding existing rule at 30 CFR 
779.24(c) applies this requirement to areas for which the applicant 
anticipates seeking additional permits. However, in practice, 
regulatory authorities do not always require a new permit application 
for additional acreage to be mined. Some state regulatory programs 
allow expansion by means of permit amendments or revisions. We have 
approved state program amendments of this nature, provided that the 
program amendment specifies that the permit amendment or revision 
application is subject to the same information requirements as a new 
permit and that the application must be processed and approved in the 
same manner as a new permit. We have found that amendments containing 
those provisions are no less stringent than section 510(a)(3) of 
SMCRA,\252\ which provides that, except for incidental boundary 
revisions, any extension of the area covered by a permit must be made 
by application for a new permit. The proposed language would reflect 
this reality and ensure that the description would include all subareas 
for which the applicant anticipates seeking approval to mine in the 
future, not just those subareas for which the applicant anticipates 
seeking new permits.

    Proposed paragraphs (a)(7), (a)(8), (a)(9), (a)(18), (a)(20), and 
(a)(27) would allow certain information that is not particularly 
amenable to display on a map to instead be submitted in a table cross-
referenced to a map if approved by the regulatory authority. This 
information would include depth of water, gas and oil wells; ownership 
of wells and groundwater resources; ownership and descriptions of 
surface-water features; and elevations and geographic coordinates of 
test borings, core samplings, and monitoring stations.
    In proposed paragraph (a)(11), we propose to add a provision 
requiring mapping of all public water supplies and wellhead protection 
zones \253\ located within one-half mile of the proposed permit area. 
This information would be important in preparing the cumulative 
hydrologic impact assessment required by section 510(b)(3) of SMCRA 
\254\ and may be of value in preparing the PHC determination and 
hydrologic reclamation plan for the proposed permit.

    Proposed paragraph (a)(13) would add a requirement for a map 
showing the location of any discharge, including, but not limited to, a 
mine-water treatment or pumping facility, into or from an active, 
inactive, or abandoned underground mine that is hydrologically 
connected to the proposed permit area or that is located within one-
half mile, measured horizontally, of the proposed permit area. The 
applicant will need this information to prepare the determination of 
the probable hydrologic consequences of mining required by section 
507(b)(11) of SMCRA.\255\ In addition, the regulatory authority will 
need this information to prepare the cumulative hydrologic impact 
assessment required by the same provision of the Act and by section 
510(b)(3) of SMCRA.\256\

    We propose to add a requirement in paragraphs (a)(18) and (20) that 
the application include the geographic coordinates of test borings, 
core samplings, and monitoring stations. Our inspectors have found that 
this information often is time-consuming or difficult to locate in the 
permit file or to determine from maps included in that file, so a list 
of features with their geographic coordinates should improve the 
efficiency with which regulatory authority and OSMRE personnel perform 
their duties by greatly improving the ability of regulatory authority 
and OSMRE personnel to field-check those locations using GPS devices. 
The requirement for geographic coordinates also is intended to ensure 
that the locations of these features are determined by an actual survey 
rather than approximated on a topographic map.
    Proposed paragraph (a)(19) would expand upon the requirement in 
existing 30 CFR 779.25(a)(6) for the location and extent of subsurface 
water, if encountered, by adding provisions concerning aquifers that 
currently are found only in the corresponding requirements for 
underground mines at existing 30 CFR 783.25(a)(6). Specifically, we 
propose to require that the application include the areal and vertical 
distribution of aquifers and a portrayal of seasonal variations in 
hydraulic head in different aquifers. This information is equally 
important for proposed surface mining operations because it would be 
used to establish baseline groundwater conditions and predict the 
impacts of the proposed mining operation on those aquifers, regardless 
of whether the proposed operation is a surface mine or an underground 
mine. Furthermore, section 507(b)(14) of SMCRA,\257\ which is the 
primary statutory counterpart to proposed 30 CFR 779.24, expressly 
requires that the application include the location of aquifers. In 
addition,

[[Page 44487]]

proposed 30 CFR 779.24(a)(19) would include a requirement for the 
estimated elevation of the water table, which section 507(b)(14) of 
SMCRA also requires.
---------------------------------------------------------------------------

    \257\ 30 U.S.C. 1257(b)(14).

    In proposed paragraph (a)(21), we propose to add a requirement that 
the maps, cross-sections, and plans include the commonly used names of 
the coal seams to be mined, overburden strata, and the stratum 
immediately below the lowest coal seam to be mined. This information 
would assist reviewers in predicting the impacts of the proposed 
operation by facilitating consultation with published reference 
materials on the coal seams and geological strata in question.
    In proposed paragraph (a)(27), we propose to add a requirement that 
the application identify all directional or horizontal drilling for 
hydrocarbon extraction operations, including those using hydraulic 
fracturing methods, within or underlying the proposed permit and 
adjacent areas. Both the applicant and the regulatory authority need 
this information to determine the probable hydrologic consequences of 
the proposed operation and to ensure that the operation's design takes 
these operations and wells into consideration.

G. Part 780: Surface Mining Permit Applications--Minimum Requirements 
for Reclamation and Operation Plans

1. Section 780.1: What does this part do?
    Existing 30 CFR 780.1 states that part 780 provides the minimum 
requirements for the Secretary's approval of regulatory program 
provisions for the mining operations and reclamation plan portions of 
permit applications for surface mining activities, except to the extent 
that part 785 establishes different requirements. However, the content 
requirements and standards for approval of state regulatory programs 
are located in 30 CFR parts 730 through 732. Therefore, we propose to 
revise 30 CFR 780.1 to specify that part 780 sets forth permit 
application requirements for reclamation and operation plans for 
proposed operations.
2. Section 780.2: What is the objective of this part?
    We propose to revise this section to specifically mention 
reclamation of the disturbed area to reflect the fact that part 780 
includes numerous reclamation requirements. The existing rule only 
mentions surface mining activities. We recognize that this change is 
not essential because the definition of ``surface mining activities'' 
in 30 CFR 700.5 includes reclamation, but adding a mention of 
reclamation in 30 CFR 780.2 would make this rule clearer to the reader.
3. Section 780.12: What information must the reclamation plan include?
Paragraph (a): General Requirements
    Proposed paragraph (a) is substantively identical to existing 30 
CFR 780.18(a) with one exception. The existing rule requires that each 
permit application contain a reclamation plan showing how the applicant 
will comply with section 515 of SMCRA,\258\ the federal performance 
standards in subchapter K of 30 CFR Chapter VII, and the environmental 
protection performance standards of the regulatory program. We propose 
to revise this provision to be more consistent with section 508(a) of 
SMCRA,\259\ which requires that each reclamation plan include the 
information ``necessary to demonstrate that reclamation required by the 
State or Federal program can be accomplished.'' The existing rule is 
too limiting in that it refers only to performance standards, not to 
all reclamation requirements. In addition, the references to section 
515 of SMCRA and subchapter K of 30 CFR Chapter VII in the existing 
rule are inconsistent with the principle of state primacy under section 
503(a) of SMCRA,\260\ which specifies that a state with an approved 
regulatory program assumes exclusive jurisdiction over surface coal 
mining and reclamation operations on non-Federal, non-Indian lands 
within its borders, except as provided in sections 521 and 523 \261\ 
and title IV \262\ of the Act. Therefore, we propose to revise 
paragraph (a) by deleting the references to performance standards and 
to section 515 of SMCRA and subchapter K of 30 CFR Chapter VII. 
Instead, we propose to require that each permit application include a 
reclamation plan showing how the applicant will comply with the 
reclamation requirements of the applicable regulatory program.

Paragraph (b): Reclamation Timetable
    Section 508(a)(7) of SMCRA \263\ requires the reclamation plan for 
each permit application include ``a detailed estimated timetable for 
the accomplishment of each major step in the reclamation plan.'' 
Existing 30 CFR 780.18(b)(1) implements this provision in part. We 
propose to revise the existing rule by listing the activities which, at 
a minimum, must be considered major steps in the reclamation process. 
In typical chronological order, those steps include, but are not 
limited to, backfilling, grading, restoration of the form of all 
reconstructed perennial and intermittent stream segments, soil 
redistribution, planting, demonstration of revegetation success, 
restoration of the ecological function of all reconstructed perennial 
and intermittent stream segments, and application for each phase of 
bond release. Establishment of a timetable that includes those steps 
should promote consistency in the application of this provision and 
result in a more comprehensive timetable, which would implement section 
508(a)(7) of SMCRA more completely.
---------------------------------------------------------------------------

    \263\ 30 U.S.C. 1258(a)(7).
---------------------------------------------------------------------------

    The regulatory authority must evaluate the proposed timetable to 
determine whether it meets the contemporaneous reclamation requirements 
of section 515(b)(16) of SMCRA.\264\ Once approved as part of the 
permit, this timetable serves as a standard for evaluating compliance 
with the contemporaneous reclamation requirements of section 515(b)(16) 
of SMCRA.\265\

Paragraph (c): Reclamation Cost Estimate
    We propose to revise this paragraph, which appears at 30 CFR 
780.18(b)(2) in our existing rules, by clarifying that the cost 
estimates must include both direct and indirect costs and by requiring 
that the permit applicant use current, standardized construction cost 
estimation methods and equipment cost guides in developing estimates of 
the cost of reclamation. These changes should improve the accuracy of 
cost estimates and increase the usefulness of these estimates to the 
regulatory authority in determining the amount of performance bond 
required under section 509 of SMCRA \266\ and 30 CFR part 800.
---------------------------------------------------------------------------

    \266\ 30 U.S.C. 1259.
---------------------------------------------------------------------------

Paragraph (d): Backfilling and Grading Plan
    Proposed paragraph (d) corresponds to existing 30 CFR 780.18(b)(3). 
We propose to add more specificity to the existing rule, which requires 
``[a] plan for backfilling, soil stabilization, compacting, and 
grading, with contour maps or cross-sections that show the anticipated 
final surface configuration of the proposed permit area, in

[[Page 44488]]

accordance with 30 CFR 816.102 through 816.107.''
    Proposed paragraph (d)(1) would require that the reclamation plan 
contain a plan for backfilling the mined-out area, compacting the 
backfill, and grading the disturbed area in accordance with 30 CFR 
817.102 through 817.107 of this chapter, using the best technology 
currently available. It also would specify that the plan must limit 
compaction to the minimum necessary to achieve stability requirements 
unless additional compaction is necessary to reduce infiltration to 
minimize leaching and discharges of parameters of concern. The added 
language is intended to achieve a balance between minimizing 
compaction, which research has shown stunts the growth of most crops 
and woody plants,\267\ and the need to minimize the formation of 
discharges that contain sulfate and other ions that could have adverse 
impacts on receiving streams and their aquatic life.

145; Crossley, D. I. ``The effect of a compact subsoil horizon on 
root penetration.'' Journal of Forestry 38.10 (1940): 794-796.
---------------------------------------------------------------------------

    Proposed paragraph (d)(1) also would require that the plan be 
accompanied by models, contour maps, or cross-sections that show in 
detail the anticipated final surface elevations and configuration of 
the proposed permit area, including drainage patterns. The regulatory 
authority would use this information to determine whether the proposed 
plan satisfies the backfilling, grading, and surface configuration 
requirements of 30 CFR 816.102 through 816.107.
    Proposed paragraph (d)(2) would require that the plan describe in 
detail how the permittee will conduct backfilling and reclamation 
activities and handle acid-forming and toxic-forming materials, if 
present, to prevent the formation of acid or toxic mine drainage from 
acid-forming and toxic-forming materials within the overburden. It also 
would require an explanation of how the method selected will protect 
groundwater and surface water in accordance with 30 CFR 816.38, which 
contains the performance standards for handling acid-forming and toxic-
forming materials. Proposed paragraph (d)(2) would implement in part 
the requirements in section 515(b)(3) of SMCRA \268\ that surface coal 
mining and reclamation operations compact spoil where advisable to 
prevent leaching of toxic materials, cover all acid-forming and other 
toxic materials, and shape and grade overburden and spoil to prevent 
water pollution. It also would implement, in part, section 515(b)(14) 
of SMCRA,\269\ which requires that all acid-forming materials and toxic 
materials be ``treated or buried and compacted or otherwise disposed of 
in a manner designed to prevent contamination of ground or surface 
waters.''

Paragraph (e): Soil Handling Plan
    We propose to extensively revise our existing rules concerning 
soils to promote salvage, preservation, and redistribution of the best 
available soil materials for the purpose of creating a growing medium 
(soil) suitable for the intended vegetation, including creation of a 
root zone of sufficient depth for that vegetation. Proposed paragraph 
(e) would include those provisions of our existing rules at 30 CFR 
816.22(b) and (e) that are permitting requirements rather than 
performance standards in an effort to consolidate permit application 
information and review requirements in subchapter G rather than having 
them split between subchapters G (permit requirements) and K 
(performance standards).
    We propose to extensively revise our existing rules to better 
implement section 515(b)(5) of SMCRA,\270\ which states that surface 
coal mining operations must--
---------------------------------------------------------------------------

    \270\ 30 U.S.C. 1265(b)(5).

remove the topsoil from the land in a separate layer, replace it on 
the backfill area, or if not utilized immediately, segregate it in a 
separate pile from other spoil and when the topsoil is not replaced 
on a backfill area within a time short enough to avoid deterioration 
of the topsoil, maintain a successful cover by quick growing plant 
or other means thereafter so that the topsoil is preserved from wind 
and water erosion, remains free of any contamination by other acid 
or toxic material, and is in a usable condition for sustaining 
vegetation when restored during reclamation, except if topsoil is of 
insufficient quantity or of poor quality for sustaining vegetation, 
or if other strata can be shown to be more suitable for vegetation 
requirements, then the operator shall remove, segregate, and 
preserve in a like manner such other strata which is best able to 
---------------------------------------------------------------------------
support vegetation.

    Proposed paragraph (e)(1)(i) is similar to the first sentence of 
existing 30 CFR 780.18(b)(4). It would require that the reclamation 
plan include a plan and schedule for removal, storage, and 
redistribution of topsoil, subsoil, and other material to be used as a 
final growing medium in accordance with 30 CFR 816.22.
    Consistent with proposed 30 CFR 816.22(f), we also propose to add a 
requirement that the application include a plan for salvaging, 
protecting, and redistributing or otherwise using all organic matter 
(duff, other organic litter, and vegetative materials such as tree 
tops, small logs, and root balls) found on the site. Acceptable uses 
for organic matter are as a soil supplement, to promote revegetation, 
to assist in stream restoration, or to provide wildlife habitat. 
Preservation and distribution of organic matter on the regraded site 
would assist in meeting the requirement of section 515(b)(19) of SMCRA 
\271\ to establish on the regraded area a diverse, effective, and 
permanent vegetative cover of the same seasonal variety native to the 
area. Our proposed rule also is consistent with the findings of an 
extensive literature review of reforestation on minesites in 
Appalachia. That review recommended that ``all surface organic debris 
(including stumps, stems, roots, and litter), all soil layers, and the 
soft saprolite and weathered rock materials under the soil be removed, 
mixed in the process of excavating, hauling and dumping, and placed on 
the surface of reclaimed mine sites to a depth of 1 to 2 meters.''

---------------------------------------------------------------------------

    Proposed paragraph (e)(1)(ii) provides that the plan must require 
the removal, segregation, stockpiling, and redistribution of the B and 
C horizons and other underlying strata or portions thereof to the 
extent that those horizons and strata are needed to provide the root 
zone required to restore premining land use capability or to comply 
with the revegetation requirements of 30 CFR 816.111 and 816.116. The 
proposed rule differs from the existing rule at 30 CFR 816.22(e) in 
that the existing rule provides that salvage and redistribution of 
these soil materials is discretionary on the part of the regulatory 
authority.
    However, the subsoil (the B and C horizons) also is important for 
plant growth. Plant roots extend through the topsoil into the subsoil 
(root zone), which provides a substantial proportion of the plant's 
nutrient requirements. For example, field studies have shown that 
between 45 percent and 65 percent of nitrogen available to plants from 
the soil lies below a depth of 6 inches. During dry summer weather, 
many plants, especially deep-rooted plants like alfalfa and most trees, 
depend for their survival on moisture available in the subsoil. Alfalfa 
extracts 55 percent of its moisture requirements from soil

[[Page 44489]]

materials deeper than one foot and is capable of extracting water from 
subsoil up to 6 feet in depth. Even medium-rooted crops like wheat and 
corn extract up to 40 percent of their moisture requirements from soil 
materials deeper than one foot. Finally, many plants depend on root 
penetration well into the subsoil for physical support, especially 
where topsoil is thin. If plant roots are unable to penetrate deeply 
into a reclaimed subsoil, soil capability for plant growth will be 
degraded.\273\

Reclaiming Borrow Excavations'' (December 2013); pp. 5-6.
---------------------------------------------------------------------------

    Therefore, a failure to require salvage and redistribution of the B 
and C horizons under these conditions would result in a failure to 
restore the site to a condition in which it is capable of supporting 
those land uses that it was capable of supporting before any mining, as 
required by section 515(b)(2) of SMCRA.\274\
---------------------------------------------------------------------------

    \274\ 30 U.S.C. 1265(b)(2).
---------------------------------------------------------------------------

    Furthermore, proposed paragraph (e)(1)(ii) is consistent with, and 
would improve implementation of, section 515(b)(5) of SMCRA,\275\ which 
provides that if strata other than the topsoil ``can be shown to be 
more suitable for vegetation requirements, then the operator shall 
remove, segregate, and preserve in a like manner such other strata 
which is best able to support vegetation.'' The U.S. District Court for 
the District of Columbia upheld this interpretation of section 
515(b)(5) of SMCRA in 1980 in PSMRL I, Round I concerning the 1979 
version of our regulations at 30 CFR 816.22(d),\276\ which required 
segregation of the B horizon and portions of the C horizon if the 
regulatory authority determined that those materials were necessary or 
desirable to ensure soil productivity:
---------------------------------------------------------------------------

    \275\ 30 U.S.C. 1265(b)(5).
    \276\ 30 CFR 816.22(d) was subsequently redesignated as 30 CFR 
816.22(e) on May 16, 1983. See 48 FR 22100.

    Section 515(b)(5) authorizes segregation [of materials other 
than topsoil] if the topsoil cannot sustain vegetation or if other 
strata enhance post-mining vegetation. This is essentially what the 
regulations command. They focus on ``soil productivity,'' and grant 
the regulatory authority power to require segregation if necessary 
to improve such productivity.\277\

    Proposed paragraph (e)(1)(iii) would require that the plan explain 
how soil materials would be handled and stored to avoid contamination 
by acid-forming or toxic-forming materials and to minimize the loss of 
desirable soil characteristics during handling and storage. These 
provisions mirror similar requirements in section 515(b)(5) of 
SMCRA.\278\
---------------------------------------------------------------------------

    \278\ 30 U.S.C. 1265(b)(5).
---------------------------------------------------------------------------

    Proposed paragraph (e)(2) contains expanded criteria and 
requirements for the approval and use of soil substitutes or 
supplements. It differs from existing 30 CFR 816.22(b) most 
significantly in that the existing rule allows use of topsoil 
substitutes or supplements if the resulting soil medium is equal to or 
more suitable than the existing topsoil in terms of its capability to 
sustain vegetation. We propose to eliminate the provision allowing use 
of topsoil substitutes or supplements when the resulting growing medium 
(soil) is only equal to the existing topsoil in terms of its capability 
to sustain vegetation. Our proposed revision would improve the 
implementation of section 515(b)(5) of SMCRA,\279\ which allows use of 
other overburden strata in place of the topsoil only if those strata 
``can be shown to be more suitable for vegetation requirements.'' 
Nothing in this provision of SMCRA authorizes the use of other strata 
in place of topsoil if the resulting medium is only equal in its 
ability to meet vegetation requirements.
---------------------------------------------------------------------------

    \279\ Id.
---------------------------------------------------------------------------

    While section 515(b)(5) of SMCRA \280\ is silent on the use of 
subsoil substitutes, we propose to apply the same standards to the use 
of subsoil substitutes and supplements as we do to topsoil substitutes 
and supplements. The subsoil is an important part of the growing medium 
in that, among other things, it provides the root zone required by many 
plants for physical support, moisture, and nutrient uptake.\281\ 
Therefore, application of the same standards for subsoil substitutes as 
for topsoil substitutes is appropriate to ensure that the reclaimed 
site is restored to a condition in which it is capable of supporting 
the uses that it was capable of supporting before any mining, as 
required by section 515(b)(2) of SMCRA.\282\

    Proposed paragraph (e)(2)(i) explains that proposed paragraph 
(e)(2) would apply to all permit applicants proposing to use 
appropriate overburden materials as a supplement to or substitute for 
the existing topsoil or subsoil on the proposed permit area.
    Proposed paragraph (e)(2)(ii)(A) would require that the permit 
applicant demonstrate, and the regulatory authority find in writing, 
that either the quality of the existing topsoil and subsoil is inferior 
to that of the alternative overburden materials proposed for use or 
that the quantity of existing topsoil and subsoil is not adequate to 
provide the optimal rooting depth or to meet other growth requirements 
of the native species to be planted under the revegetation plan. In the 
latter case, the proposed rule also would require that the soil 
handling plan provide for the salvage and redistribution of all 
existing soil materials as a component of the approved growing medium 
to obtain the benefits of the native existing soil materials as a 
source of seeds, other plant propagules, mycorrhizae, other soil flora 
and fauna, and other biological components that promote revegetation. 
Studies in Appalachia have found that native soils contain nitrogen and 
phosphorus in organic forms that are readily available to plants; they 
also contain organic carbon that is essential to soil microorganisms 
and nutrient cycling.\283\ The author of an extensive literature review 
of reforestation on minesites in Appalachia concluded that native soils 
``will be the most favorable material available on most mine sites for 
use in constructing mine soils for reforestation'' and that, when use 
of rock spoil is necessary, the native soils, as well as stumps and 
woody debris, should be mixed with those spoils to enhance their 
chemical, biological, and physical properties.\284\

    Proposed paragraph (e)(2)(ii)(B) would require that the permit 
applicant demonstrate, and the regulatory authority find in writing, 
that use of the alternative overburden materials, either in combination 
with or in place of the topsoil or subsoil, would result in a growing 
medium (soil) that will provide superior rooting depth in comparison to 
the existing topsoil and subsoil and that will be more suitable to 
sustain the vegetation required by the approved postmining land use and 
the revegetation plan than the existing topsoil and subsoil.
    Proposed paragraph (e)(2)(ii)(C) would require that overburden 
materials selected for use as a soil substitute or supplement be the 
best materials available in the proposed permit area to support the 
native vegetation to be established on the reclaimed area or the crops 
to be planted on that area.
    The demonstrations and findings required by proposed paragraphs 
(e)(2)(ii)(A) through (C) would, in part, improve implementation of 
section

[[Page 44490]]

515(b)(5) of SMCRA,\285\ which provides that ``if topsoil is of 
insufficient quantity or of poor quality for sustaining vegetation, or 
if other strata can be shown to be more suitable for vegetation 
requirements, then the operator shall remove, segregate, and preserve 
in a like manner such other strata which is best able to support 
vegetation.'' In addition, these demonstrations and findings are 
intended to ensure the establishment of a growing medium on the 
reclaimed area that is capable of supporting the uses that the land was 
capable of supporting before any mining, as required by section 
515(b)(2) of SMCRA.\286\ Finally, the emphasis on the use of native 
species to determine optimal rooting depths and other growth 
requirements when evaluating the suitability of potential soil 
substitutes is consistent with section 515(b)(19) of SMCRA,\287\ which 
requires establishment of a diverse, effective, and permanent

    Proposed paragraphs (e)(2)(iii) and (iv) would expand upon the 
second and third sentences of existing 30 CFR 780.18(b)(4), which 
establish minimum content requirements for the demonstration of the 
suitability of potential soil substitutes or supplements and which 
allow the regulatory authority to require other analyses, field trials, 
or greenhouse tests if necessary. Proposed paragraph (e)(2)(iii) would 
require that the regulatory authority specify suitability criteria for 
potential soil substitutes and supplements; chemical and physical 
analyses, field trials, or greenhouse tests that the applicant must 
conduct on potential soil substitutes and supplements; and sampling 
objectives, sampling techniques, and the techniques to be used to 
analyze the samples collected. Proposed paragraph (e)(2)(iv)(A) would 
require that demonstrations of the suitability of potential soil 
substitutes and supplements include the physical and chemical soil 
characteristics and root zones needed to support the type of vegetation 
to be established on the reclaimed area. Proposed paragraph 
(e)(2)(iv)(B) would require that those demonstrations include a 
comparison and analysis of the thickness, total depth, texture, percent 
coarse fragments, pH, thermal toxicity, and areal extent of the 
different kinds of soil horizons and overburden materials available 
within the proposed permit area, based upon a statistically valid 
sampling procedure.
    Proposed paragraphs (e)(2)(iii) and (iv) are intended to ensure 
that the determination of the suitability of potential soil substitutes 
and supplements is conducted in a scientifically-sound manner. Use of 
scientifically-invalid sampling and analytical techniques or a lack of 
comprehensive criteria for the evaluation and approval of potential 
soil substitutes and supplements could result in the establishment of 
an inferior growing medium on the reclaimed area that is incapable of 
supporting the uses that it was capable of supporting before any 
mining. Such a result would be inconsistent with section 515(b)(2) of 
SMCRA.\288\ It also would be inconsistent with the requirement in 
section 515(b)(5) of SMCRA \289\ that any topsoil substitutes be shown 
to be more suitable for vegetation requirements than the existing soil 
and that any substitute materials be the best able to support 
vegetation.

    Proposed paragraph (e)(2)(v) would require that the soil handling 
plan include a plan for testing and evaluating overburden materials 
during both removal and redistribution to ensure that the permittee 
removes and redistributes only those overburden materials approved for 
use as soil substitutes or supplements. This requirement would provide 
a safeguard against the salvage and redistribution of overburden 
materials that have not been approved for use as soil substitutes or 
supplements. Use of unapproved materials could result in the 
establishment of an inferior growing medium on the reclaimed area that 
is incapable of supporting the uses that it was capable of supporting 
before any mining. Such a result would be inconsistent with section 
515(b)(2) of SMCRA.\290\ It also would be inconsistent with the 
requirement in section 515(b)(5) of SMCRA \291\ that any topsoil 
substitutes be shown to be more suitable for vegetation requirements 
than the existing soil and that any substitute materials be the best 
able to support vegetation.

Paragraph (f): Surface Stabilization Plan
    We propose to add this paragraph to replace existing 30 CFR 780.15, 
which requires that the reclamation plan include an air pollution 
control plan for fugitive dust. Under existing 30 CFR 780.15, at a 
minimum, the permit application must include a ``plan for fugitive dust 
control practices, as required under 30 CFR 816.95.'' We propose to 
remove 30 CFR 780.15 because the references to fugitive dust and cross-
references to 30 CFR 816.95 in the existing rule refer to provisions 
that we removed in 1983 in response to a court decision striking down 
our authority to regulate air pollution under SMCRA, except for air 
pollution attendant to erosion. The court held that ``the legislative 
history indicates that Congress only intended to regulate air pollution 
related to erosion.'' \292\ The 1983 rulemaking removed all 
requirements in 30 CFR 816.95 for fugitive dust control practices, 
including requirements for monitoring of fugitive dust to determine 
compliance with federal and state air quality standards. That 
rulemaking also changed the section heading of 30 CFR 816.95 from ``Air 
resources protection'' to ``Stabilization of surface areas'' and 
replaced the air quality performance standards formerly located in that 
section with soil stabilization requirements that contain no mention of 
fugitive dust or air quality monitoring. See 48 FR 1160-1163 (Jan. 10, 
1983).

---------------------------------------------------------------------------

    However, the 1983 rulemaking did not remove the parallel permitting 
requirements in 30 CFR 780.15 and 784.26. Instead, we stated in the 
preamble to that rulemaking that we agreed with a commenter that we 
also needed to amend the permit application rules at 30 CFR 780.15 and 
784.26 for consistency with the revisions to 30 CFR 816.95 and 817.95, 
and that we would do so in a subsequent independent rulemaking.\293\ 
Adoption of this proposed rule would fulfill that commitment in part by 
adding permit application information requirements consistent with the 
1983 revisions to 30 CFR 816.95. In other words, we propose to replace 
the obsolete air pollution control plan requirements in existing 30 CFR 
780.15 with the surface stabilization plan requirements in proposed 30 
CFR 780.12(f) to correspond with the requirements in existing 30 CFR 
816.95, as revised in 1983.
---------------------------------------------------------------------------

    \293\ 48 FR 1161 (Jan. 10, 1983).
---------------------------------------------------------------------------

    Proposed paragraph (f) would add a permitting counterpart to the 
current performance standard at 30 CFR 816.95(a), which provides that 
all exposed surface areas must be protected and stabilized to 
effectively control erosion and air pollution attendant to

[[Page 44491]]

erosion. We also propose to add cross-references to the current dust 
control performance standards for roads in 30 CFR 816.150 and 816.151.
Paragraph (g): Revegetation Plan
    We propose to extensively revise this paragraph, which appears at 
30 CFR 780.18(b)(5) in our existing rules, by adding specificity for 
elements of the revegetation plan, by incorporating those provisions of 
30 CFR 816.111 that are more appropriately considered permitting 
requirements rather than performance standards, and by ensuring that 
there is a detailed counterpart in the revegetation plan to the 
revegetation performance standards in 30 CFR 816.111 through 816.116, 
when appropriate. The various components of proposed paragraph (g) are 
intended to ensure compliance with or improve implementation of section 
515(b)(19) of SMCRA,\294\ which requires that surface coal mining and 
reclamation operations establish ``a diverse, effective, and permanent 
vegetative cover of the same seasonal variety native to the area of 
land to be affected and capable of self-regeneration and plant 
succession at least equal in extent of cover to the natural vegetation 
of the area; except, that introduced species may be used in the 
revegetation process where desirable and necessary to achieve the 
approved postmining land use plan.''
---------------------------------------------------------------------------

    \294\ 30 U.S.C. 1265(b)(19).
---------------------------------------------------------------------------

    Proposed paragraph (g)(1)(ii) would add a site preparation element 
to the revegetation plan to reflect extensive research documenting the 
adverse impacts of excessive compaction on vegetation, especially woody 
plants. The new element would require a description of the measures 
that the permittee will take to avoid compaction or, when avoidance is 
not possible, to minimize and alleviate compaction of the root zone 
during backfilling, grading, soil redistribution, and planting.
    In addition, we propose to require in paragraph (g)(1)(viii) that 
the revegetation plan identify any normal husbandry practices that the 
permittee intends to use and explain whether the permittee intends to 
conduct irrigation or apply fertilizer after the first year and, if so, 
for how long and to what extent. This information will assist the 
regulatory authority in determining whether the proposed practices are 
normal husbandry practices or whether they are augmentative in nature, 
which would necessitate restarting the revegetation responsibility 
period under proposed 30 CFR 816.115, which corresponds to existing 30 
CFR 816.116(c). These provisions would serve as the permit application 
information counterpart to the performance standards in proposed 30 CFR 
816.115(a)(1) and (b), which correspond to existing 30 CFR 
816.116(c)(1) and (c)(4).
    Proposed paragraph (g)(1)(xi) would add a requirement that the 
revegetation plan include the measures that the permittee will take to 
avoid the establishment of invasive species on reclaimed areas or to 
control those species if they do become established. Invasive species 
are highly detrimental to native ecosystems, agriculture, and forestry. 
They have posed a problem on some minesites either because the permit 
improperly allowed the use of invasive non-native species or because of 
the reclamation practices used. We propose to add this provision to 
improve the implementation of section 515(b)(19) of SMCRA,\295\ which 
requires the establishment of a diverse, effective, and permanent 
vegetative cover of the same seasonal variety native to the area, and 
section 515(b)(2) of SMCRA,\296\ which requires restoration of mined 
land to a condition capable of supporting the uses it was capable of 
supporting before any mining. Allowing the establishment of invasive 
species also would be inconsistent with the fish and wildlife 
protection provisions of section 515(b)(24) of SMCRA.\297\ Moreover, 
proposed paragraph (g)(1)(xi) is consistent with Section 2.(a)(2)(i) 
and (iv) of Executive Order 13112, ``Invasive Species,'' which requires 
that ``[e]ach Federal agency whose actions may affect the status of 
invasive species shall, to the extent practicable and permitted by law, 
. . . (i) prevent the introduction of invasive species; . . . [and] 
(iv) provide for the restoration of native species and habitat 
conditions in ecosystems that have been invaded.'' \298\

---------------------------------------------------------------------------

    Proposed paragraph (g)(2) would require that the plan be designed 
to create a diverse, effective, permanent vegetative cover that is 
consistent with the vegetative communities described in the permit 
application in accordance with 30 CFR 779.19. It also would require 
that the plan meet the other requirements of 30 CFR 816.116(a) and (b).
    Proposed paragraph (g)(3) is substantively identical to the 
species-selection criteria of existing 30 CFR 816.111(a)(2), (a)(4), 
and (b), with two exceptions. Proposed paragraph (g)(3)(i) would 
prohibit the use of introduced species unless they are non-invasive. 
This proposed requirement is consistent with section 515(b)(19) of 
SMCRA,\299\ which allows the use of introduced species only if they are 
desirable. Invasive introduced species are not desirable because they 
out-compete native vegetation and can have adverse impacts on fish and 
wildlife, which would be inconsistent with the fish and wildlife 
protection requirements of section 515(b)(24) of SMCRA.\300\ Moreover, 
proposed paragraph (g)(3)(i) is consistent with Section 2.(a)(2)(i) of 
Executive Order 13112, ``Invasive Species,'' which requires that 
``[e]ach Federal agency whose actions may affect the status of invasive 
species shall, to the extent practicable and permitted by law, . . . 
prevent the introduction of invasive species''.\301\

---------------------------------------------------------------------------

    Proposed paragraph (g)(3)(ii) would provide that the species 
selected need to be capable of stabilizing the soil surface from 
erosion only to the extent that control of erosion with herbaceous 
species is consistent with establishment of a permanent vegetative 
cover that resembles native plant communities in the area. We propose 
to add this qualifier because some level of erosion is natural and 
because excessive herbaceous cover can inhibit establishment of woody 
plants, as discussed at length elsewhere in this preamble.
    Proposed paragraphs (g)(4) and (g)(5) are substantively identical 
to existing 30 CFR 816.116(c) and (d). Both paragraphs would provide 
limited exceptions to the species-selection requirements of proposed 
paragraphs (g)(3)(i), (iv), and (v), which correspond to the species-
selection provisions of section 515(b)(19) of SMCRA.\302\ Proposed 
paragraph (g)(3) would provide an exception for temporary cover, while 
proposed paragraph (g)(4) would provide an exception for long-term, 
intensive agricultural postmining land uses. These exceptions would be 
consistent with section 515(b)(19) of SMCRA,\303\ which allows the use 
of introduced species ``in the revegetation process where desirable and 
necessary to achieve the approved postmining land use plan.'' Proposed 
paragraph (g)(4) also would implement section 515(b)(20) of SMCRA \304\ 
to the extent that it provides exceptions to the requirements of 
section 515(b)(19) for

[[Page 44492]]

long-term, intensive agricultural postmining land uses.

    Proposed paragraph (g)(6) would require that a professional 
forester or ecologist develop and certify all revegetation plans that 
include the establishment of trees and shrubs. It also would require 
that those plans include site-specific planting prescriptions for 
canopy trees, understory trees and shrubs, and herbaceous ground cover 
compatible with establishment of those trees and shrubs. In addition, 
this proposed paragraph would require that the plan rely exclusively 
upon the use of native species unless those species are inconsistent 
with the approved postmining land use and that land use is implemented 
before the entire bond amount for the area in question has been fully 
released.
Paragraph (h): Stream Restoration Plan
    We propose to add this paragraph to require that the reclamation 
plan expressly address in detail how the permittee will restore the 
form and ecological function of each segment of a perennial or 
intermittent stream that is proposed to be mined through under 30 CFR 
780.28. The plan must conform to the requirements of 30 CFR 780.28 and 
816.57. The U.S. Army Corps of Engineers may require additional onsite 
or offsite mitigation under section 404 of the Clean Water Act.\305\

Paragraph (i): Coal Resource Conservation Plan
    Proposed paragraph (i) corresponds to existing 30 CFR 780.18(b)(6). 
We propose to add language consistent with the existing coal recovery 
performance standard at 30 CFR 816.59. Proposed paragraph (i) would 
implement section 508(a)(6) of SMCRA,\306\ which provides that the 
reclamation plan must include a statement of ``the consideration which 
has been given to maximize the utilization and conservation of the 
solid fuel resource being recovered so that reaffecting the land in the 
future can be minimized.''
---------------------------------------------------------------------------

    \306\ 30 U.S.C. 1258(a)(6).
---------------------------------------------------------------------------

Paragraph (j): Plan for Disposal of Noncoal Waste Materials
    Proposed paragraph (j) corresponds to existing 30 CFR 780.18(b)(7). 
We propose to clarify that this requirement applies to all noncoal 
waste materials resulting from mining and reclamation activities, but 
not to coal combustion residuals such as fly ash and bottom ash. The 
existing rule applies to ``debris, acid-forming and toxic-forming 
materials, and materials constituting a fire hazard.'' We propose to 
delete the reference to acid-forming and toxic-forming materials 
because proposed 30 CFR 780.22 contains the permit application 
information requirements for those materials. As revised, proposed 
paragraph (j) would apply to all noncoal waste materials covered by 30 
CFR 816.89. It would serve as the permit application information 
counterpart to the performance standards for disposal of noncoal waste 
materials in 30 CFR 816.89.
    We also propose to require that the reclamation plan describe the 
type and quantity of noncoal waste materials that the permittee intends 
to dispose of within the proposed permit area, how the permittee 
intends to dispose of those materials in accordance with 30 CFR 816.89, 
and the locations of any noncoal waste material disposal sites within 
the proposed permit area, as well as the contingency plans developed to 
preclude sustained combustion of combustible noncoal materials. These 
permit application information requirements would enable the regulatory 
authority to evaluate the potential environmental impacts of the 
disposal of noncoal waste materials and ensure that the permit includes 
appropriate measures to protect society and the environment from the 
adverse effects of this aspect of surface coal mining operations, as 
provided in section 102(a) of SMCRA.\307\

    \307\ 30 U.S.C. 1202(a).

Paragraph (m): Consistency With Land Use Plans and Landowner Plans
    In the existing rules, this paragraph appears in 30 CFR 
780.23(b)(3). However, section 780.23(b) applies only in the context of 
the postmining land use, which is not consistent with the underlying 
statutory requirement at section 508(a)(8) of SMCRA.\308\ That 
provision of the Act requires that the reclamation plan describe the 
consideration that has been given to making the surface coal mining and 
reclamation operations themselves consistent with surface owner plans 
and applicable state and local land use plans and programs. This 
provision is separate and distinct from the requirement in section 
508(a)(3) of the Act \309\ that the reclamation plan discuss the 
relationship of the postmining land use to existing land use policies 
and plans and the comments of the surface owner. Therefore, we propose 
to move the provision in existing 30 CFR 780.23(b)(3) to new Sec.  
780.12(m) to ensure that, in discussing consistency with surface owner 
plans and applicable state and local land use plans, the reclamation 
plan addresses the consistency of the proposed operations (not just the 
proposed postmining land use) with those plans.

We also propose to combine existing paragraphs (a) and (b) into 
paragraph (a) and redesignate existing paragraph (c) as paragraph (b).
    We propose to remove the requirement in existing 30 CFR 
780.14(b)(7) for maps showing each air pollution collection and control 
facility because that requirement is associated with regulations in 30 
CFR 816.95 that the court struck down in 1980 and that we removed in 
1983. Specifically, the court struck down our authority to regulate air 
pollution under SMCRA, except for air pollution attendant to 
erosion.\310\ See the portion of this preamble concerning our proposed 
removal of 30 CFR 780.15 for additional discussion.

    In proposed paragraph (a)(7), which corresponds to existing 
paragraph (b)(6), we propose to add a requirement for a map showing the 
location of each point at which water will be discharged from the 
proposed permit area to a surface-water body and the name of that water 
body, consistent with equivalent requirements in sections 507(b)(10) 
and (14) of SMCRA.\311\

    In proposed paragraph (a)(11), which corresponds to existing 
paragraph (b)(11), we propose to replace the terms ``coal processing 
waste bank'' and ``coal processing waste dam and embankment'' with 
``refuse pile'' and ``coal mine waste impounding structure'' to employ 
terminology consistent with the definitions and performance standards 
that we adopted on September 26, 1983 (48 FR 44006). We also propose to 
add a reference to siltation structures, consistent with our addition 
of that terminology and requirements for those structures on September 
26, 1983 (48 FR 44032).
    We propose to add paragraphs (a)(12) through (a)(14), which would 
require a map showing each segment of a perennial or intermittent 
stream that would be mined through, buried, or diverted; any perennial 
or intermittent stream segment to be restored, any temporary or 
permanent stream-channel

[[Page 44493]]

diversion, and each segment of a perennial or intermittent stream that 
would be improved as part of the fish and wildlife enhancement plan. 
The regulatory authority would need this information to assist in 
evaluating whether the proposed application is in compliance with 
requirements pertaining to activities in perennial and intermittent 
streams in proposed 30 CFR 780.28 and 816.57.
    We also propose to add paragraph (a)(15), which would require a map 
showing the location and geographic coordinates of each point at which 
the applicant proposes to monitor groundwater, surface water, or the 
biological condition of perennial and intermittent streams. The 
regulatory authority would need this information to determine whether 
the application includes a sufficient number of monitoring sites and 
whether those sites are adequately distributed and located to ensure 
that monitoring results are representative of the entire permit area, 
as required by proposed 30 CFR 780.23.
    In addition, we propose to revise existing 30 CFR 780.14(c), which 
we propose to redesignate as 30 CFR 780.13(b), by replacing the cross-
references to 30 CFR 780.35(c) and 816.71(b) with a cross-reference to 
30 CFR 780.35 to be consistent with other changes that we are proposing 
to those rules. Those changes include moving the design certification 
requirement formerly located in section 816.71(b) to 30 CFR 780.35(b) 
to consolidate permitting requirements in subchapter G. The existing 
rules also include a cross-reference to the certification requirements 
in 30 CFR 816.73(c) for durable rock fills. We do not propose to 
include a similar cross-reference in 30 CFR 780.13(b) because we are 
proposing to remove 30 CFR 816.73 in its entirety, which means that 
durable rock fills would no longer be allowed.
    We propose to add paragraph (c), which would authorize the 
regulatory authority to require submission of the information required 
by paragraph (a) in a digital format, when appropriate. We invite 
comment on whether submission of this information in a digital format 
should be mandatory rather than discretionary to facilitate review and 
analysis by the public and the regulatory authority.
5. Why are we proposing to remove existing 30 CFR 780.15?
    We propose to remove existing 30 CFR 780.15 and redesignate 
existing 30 CFR 780.13 as 30 CFR 780.15 because the references to 
fugitive dust and cross-references to 30 CFR 816.95 in existing 30 CFR 
780.15 refer to provisions that we removed in 1983 in response to a 
court decision striking down our authority to regulate air pollution 
under SMCRA, except for air pollution attendant to erosion. The court 
held that ``the legislative history indicates that Congress only 
intended to regulate air pollution related to erosion'' \312\ and that 
``the Secretary's authority to regulate [air] pollution is limited to 
activities related to erosion.'' \313\ The court remanded former 30 CFR 
816.95 and 817.95 (1979), which contained performance standards for 
fugitive dust control, for revision. However, the court did not address 
the parallel permitting requirements at 30 CFR 780.15 and 784.26.

    The 1983 rulemaking removed all requirements in 30 CFR 816.95 for 
fugitive dust control practices, including requirements for monitoring 
of fugitive dust to determine compliance with federal and state air 
quality standards. That rulemaking also changed the section heading of 
30 CFR 816.95 from ``Air resources protection'' to ``Stabilization of 
surface areas'' and replaced the air quality performance standards 
formerly located in 30 CFR 816.95 with soil stabilization requirements

48 FR 1160-1163 (Jan. 10, 1983).
    However, the 1983 rulemaking did not remove the parallel permitting

6. Section 780.16: What must I include in the fish and wildlife 
protection and enhancement plan?
    Proposed 30 CFR 780.16 is the counterpart to paragraphs (b) and (c) 
of existing 30 CFR 780.16. Our proposed revisions to the existing rule 
would provide greater specificity on the measures that the fish and 
wildlife protection and enhancement plan in the permit application must 
include. The proposed revisions would improve implementation of section 
515(b)(24) of SMCRA,\315\ which provides that ``to the extent possible 
using the best technology currently available,'' surface coal mining 
and reclamation operations must ``minimize disturbances and adverse 
impacts of the operation on fish, wildlife, and related environmental

The proposed revisions also are consistent with paragraphs (a) and (d) 
of section 102 of SMCRA,\316\ which provide that two of the purposes of 
SMCRA are establishing ``a nationwide program to protect society and 
the environment from the adverse effects of surface coal mining 
operations'' and assuring ``that surface coal mining operations are so 
conducted as to protect the environment.''

    Likewise, the proposed revisions to 30 CFR 780.16 are consistent

mining and reclamation operations ``meet such other criteria as are

    Proposed paragraph (a) contains general requirements analogous to 
existing 30 CFR 780.16(b)(1) and (2). Like the existing rules, it 
provides that the fish and wildlife protection and enhancement plan 
must be consistent with the performance standards for fish and wildlife 
protection and enhancement at 30 CFR 816.97 and must be specific to the 
fish and wildlife resources of the proposed permit and adjacent areas 
as identified in the permit application in accordance with 30 CFR 
779.20. We propose to add a requirement that the plan also comply with 
the specific protection and enhancement requirements of 30 CFR 
780.16(b) through (e).
    Proposed paragraph (b) concerns protection of threatened and 
endangered species. Like the existing rule, it would require a 
description of how the proposed operation will comply with the 
Endangered Species Act. We

[[Page 44494]]

propose to add a provision that would expressly require that the fish 
and wildlife protection and enhancement plan contain a description of 
any species-specific protection and enhancement plans developed under 
the Endangered Species Act, which would include any plans developed in 
accordance with the existing formal section 7(a)(2) Endangered Species 
Act consultation pertaining to the approval and conduct of surface coal 
mining and reclamation operations under a SMCRA regulatory program. We 
propose to add these provisions in response to discussions with the 
U.S. Fish and Wildlife Service concerning compliance with the 
Endangered Species Act.
    Proposed paragraph (c) would contain requirements for the 
protection of fish and wildlife other than threatened and endangered 
species. It would require that the fish and wildlife protection and 
enhancement plan describe how, to the extent possible using the best 
technology currently available, the proposed operation will minimize 
disturbances and adverse impacts on fish, wildlife, and related 
environmental values, as required by section 515(b)(24) of SMCRA.\320\ 
It lists a number of measures that the fish and wildlife protection and 
enhancement plan must include to minimize disturbance and adverse 
impacts, including timing of operations to avoid or minimize disruption 
to wildlife and retention of forest cover and native vegetation for as 
long as possible.

---------------------------------------------------------------------------

    As discussed below, riparian (streamside) vegetation plays a 
critical role in maintaining or restoring the ecological function of a 
stream. Therefore, proposed paragraph (c)(3) would specify that the 
fish and wildlife enhancement plan must require maintenance of an 
intact forested buffer at least 100 feet wide between surface 
disturbance and a perennial or intermittent stream to the extent 
possible. This requirement would apply only when the stream is located 
in a forested area.
    Researchers have found that, in small, well-shaded upland streams, 
as much as 75 percent of the organic food base may be supplied by 
dissolved organic compounds or detritus such as fruit, limbs, leaves 
and insects that fall from the forest canopy in the riparian zone. 
\321\ Benthic detritivores (bacteria, fungi and invertebrates) that 
live on the stream bottom feed on the detritus and form the basis of 
the aquatic food chain. They pass on this energy when they are, in 
turn, consumed by larger benthic fauna and eventually by fish. Thus, 
the streamside forest functions as an important energy source for the 
entire aquatic food chain from headwaters to estuary.\322\

    Furthermore, forested riparian buffers are essential to prevent 
excessively high water temperatures in coldwater streams and to 
moderate temperature variations in other streams. One study found a 
four-fold decline in fish density in coldwater streams after removal of 
the forested riparian buffer.\323\ Another study found that 
invertebrate populations in streams with forested buffers of 100 feet 
exhibited no change following clearcutting of the area outside the 
buffer zone. However, streams in watersheds in which clearcutting 
operations left narrower forested buffers experienced significant 
changes in the species diversity of invertebrate populations, with the 
extent of the changes correlating to buffer width.\324\

    Studies of effective buffer widths for wildlife generally recommend 
wider buffers than those required for sediment control and protection 
of water quality. For example, recommended buffer widths for 
conservation of forest-dwelling birds often exceed 300 feet.\325\ A 
comprehensive guide to riparian forest buffers in the Chesapeake Bay 
watershed provides a range of recommended minimum buffer widths for 
different objectives: 50 to 275 feet for wildlife habitat, 60 to 225 
feet for flood mitigation, 50 to 175 feet for sediment removal, 35 to 
140 feet for nitrogen removal, 20 to 60 feet for water temperature 
moderation, and 20 to 45 feet for bank stabilization and aquatic food 
web maintenance.\326\ The minimum 100-foot buffer width that we propose 
to adopt lies within the lower end of the range of recommended minimum 
widths for wildlife habitat and flood mitigation, in the middle of the 
range for sediment removal and nitrogen removal, and exceeds the range 
recommended for water temperature moderation and bank stabilization and 
aquatic food web maintenance. Therefore, the 100-foot minimum width 
that we have proposed for the riparian buffer is an appropriate 
midrange compromise that strikes a balance among property rights and 
the various recommended buffer widths for relevant objectives, 
consistent with section 102(f) of SMCRA,\327\ which provides that one 
of the purposes of SMCRA is to strike a balance between environmental 
protection and the need for coal production.

    We propose to specify that the buffer width must be measured 
horizontally on a line perpendicular to the stream beginning at the 
bankfull elevation or, if there are no discernible streambanks, the 
centerline of the active channel. We derived this provision primarily 
from Natural Resources Conservation Service Conservation Practice 
Standard Code 391 (``Riparian Forest Buffer'') (July 2010), which 
states: ``Measurement shall begin at and perpendicular to the normal 
water line, bank-full elevation, or the top of the bank as determined 
locally.'' For streams that lack defined banks, our proposed rule would 
adopt the standard used in a riparian buffer conservation zone model 
ordinance, which calls for measurement from the centerline of the 
stream in those circumstances.\328\

    Another measure listed in proposed paragraph (c) is a requirement 
for periodic evaluation of the impacts of the operation on fish, 
wildlife, and related environmental values in the permit and adjacent 
areas. This paragraph would require that the permittee use that 
information to modify operations or take other action if necessary to 
avoid or minimize unforeseen adverse impacts on fish, wildlife, and 
related environmental values.
    Proposed paragraph (d)(1) would require that the fish and wildlife 
protection and enhancement plan include a description of the measures 
that the permit applicant proposes to implement as the best technology 
currently available to enhance fish, wildlife, and related 
environmental values both within and outside the area

[[Page 44495]]

to be disturbed by mining activities, where practicable. If the 
applicant determines that it is not practicable to implement any 
enhancement measures, the application would have to explain the 
rationale for this determination. Proposed paragraphs (d)(1)(i) through 
(xi) list examples of potential enhancement measures. However, the 
applicant may select other measures. There is no expectation that each 
application will include all the measures listed here.
    Under proposed paragraph (d)(2), implementation of fish and 
wildlife enhancement measures would be mandatory whenever the proposed 
operation would result in the long-term loss of native forest, other 
native plant communities, or a segment of a perennial or intermittent 
stream. In this context, ``long-term'' means that the permittee would 
not be able to correct the resource loss before expiration of the 
period of extended revegetation responsibility as prescribed in 
proposed 30 CFR 816.115. Thus, the removal of significant native forest 
cover and the loss of the ecological benefits associated with that 
cover would be considered a long-term loss, as would the burial of a 
perennial or intermittent stream segment by an excess spoil fill or 
coal mine waste disposal facility.
    We invite comment on whether there are other interpretations of 
``long-term'' that we should consider. We also invite comment on 
whether the regulatory authority may consider mitigation measures 
approved under the authority of the Clean Water Act as satisfying the 
separate SMCRA requirement for mandatory enhancement measures. 
Acceptance may enhance coordination of permitting reviews under SMCRA 
and the Clean Water Act. We request that anyone with data on the 
effectiveness and long-term viability of Clean Water Act mitigation 
measures that have already been implemented submit that data to us for 
consideration in our decision as to whether to accept Clean Water Act 
mitigation measures as fish and wildlife enhancement measures under 
SMCRA. We also request that anyone with data on downstream impacts from 
coal mining and the effectiveness of Clean Water Act mitigation 
measures on those impacts submit that data to us for consideration. 
Finally, we request that anyone with data on the cumulative downstream 
impacts of coal mining that are not addressed by Clean Water Act 
mitigation measures or National Pollutant Discharge Elimination System 
(NPDES) permits submit that data to us for consideration.
    Proposed paragraph (d)(2)(ii) would require that the scope of the 
enhancement measures be commensurate with the potential long-term 
adverse impact to those resources and that the measures be permanent in 
nature. For example, riparian corridors must be protected by 
conservation easements (dedicated to an appropriate agency or 
organization) or deed restrictions or so that the newly planted 
vegetation is not destroyed after bond release and termination of 
jurisdiction under SMCRA. We invite comment on whether our regulations 
should define ``commensurate'' in this context and, if so, how we 
should define that term.
    Proposed paragraph (d)(2)(iii)(A) would require that enhancement 
measures be implemented within the watershed in which the proposed 
operation is located, unless opportunities for enhancement are not 
available within that watershed. In the latter situation, the proposed 
rule would allow the permit applicant to propose enhancement measures 
for implementation in the nearest adjacent watershed in which 
enhancement opportunities exist. Proposed paragraph (d)(2)(iii)(B) 
would require that each regulatory program prescribe the size of the 
watershed for purposes of paragraph (d)(2)(iii)(A) of this section, 
using a generally-accepted watershed classification system. We invite 
comment on whether we should instead establish a standard size 
nationwide as part of the final rule. The HUC-12 (U.S. Geological 
Survey 12-digit Watershed Boundary Dataset) watershed is one 
possibility.
    Proposed paragraph (d)(2)(iv) would require that completion of 
mandatory enhancement measures be made a condition of permit issuance 
to ensure that this requirement is both enforceable and covered by the 
performance bond posted for the operation.
    Proposed paragraph (d)(3) would require that the area to be 
disturbed by implementation of enhancement measures be included within 
the proposed permit area whenever implementation of those measures 
would result in more than a de minimis disturbance of the surface of 
land outside the area to be mined. This provision would ensure that the 
regulatory authority can enforce implementation of those measures under 
the SMCRA permit and that their implementation would be covered by the 
performance bond for the operation.
    Proposed paragraph (e) would contain the U.S. Fish and Wildlife 
Service permit application review provisions located at existing 30 CFR 
780.16(c). We propose to revise these provisions in response to 
discussions with the U.S. Fish and Wildlife Service concerning 
compliance with the Endangered Species Act.
    Proposed paragraph (e)(1)(i) would require that the regulatory 
authority provide the fish and wildlife protection and enhancement plan 
developed under this section as part of the permit application to the 
applicable regional or field office of the U.S. Fish and Wildlife 
Service whenever the resource information submitted under proposed 30 
CFR 779.20 includes species listed as threatened or endangered under 
the Endangered Species Act, critical habitat designated under that law, 
or species proposed for listing as threatened or endangered under that 
law. The proposed rule would require that the regulatory authority 
provide this information to the Service no later than the time that the 
regulatory authority provides written notice of receipt of an 
administratively complete permit application to the Service under 
proposed 30 CFR 773.6(a)(3)(ii). Under existing 30 CFR 780.16(c), the 
Service must request this information from the regulatory authority 
rather than receiving it automatically.
    Proposed paragraph (e)(1)(ii) is similar to existing 30 CFR 
780.16(c) in that it would allow the Service to request an opportunity 
to review the fish and wildlife protection and enhancement plans 
submitted as part of other permit applications even when the resource 
information in those applications does not include species listed as 
threatened or endangered under the Endangered Species Act, critical 
habitat designated under that law, or species proposed for listing as 
threatened or endangered under that law. Under both the existing and 
proposed rules, the regulatory authority must provide that information 
to the Service within 10 days of receipt of the request.
    Proposed paragraph (e)(2) would specify how the regulatory 
authority must handle comments received from the Service and how any 
disagreements are to be resolved. Proposed paragraph (e)(2) generally 
parallels the provisions that we and the Service agreed to as a result 
of a formal section 7(a)(2) Endangered Species Act consultation 
pertaining to the approval and conduct of surface coal mining and 
reclamation operations under a SMCRA regulatory program. Specifically, 
proposed paragraphs (e)(2)(i) through (iii) would provide that if the 
regulatory authority does not agree with a Service recommendation that 
pertains to fish and wildlife or plants listed as threatened or 
endangered under the

[[Page 44496]]

Endangered Species Act or to critical habitat designated under that 
law, the regulatory authority must explain the rationale for that 
decision in a comment disposition document and must provide a copy of 
that document to the pertinent Service field office. The proposed rule 
also would require that the regulatory authority provide a copy of that 
document to the appropriate OSMRE field office for informational 
purposes and to allow the OSMRE field office to monitor resolution of 
the disagreement. If the Service field office does not concur with the 
regulatory authority's decision and the regulatory authority and the 
Service field office are subsequently unable to conclude an agreement 
at that level, the proposed rule allows either the regulatory authority 
or the Service to elevate the issue through the chain of command of the 
regulatory authority, the Service, and OSMRE for resolution.
    Proposed paragraph (e)(2)(iv) would provide that the regulatory 
authority may not approve the permit application until all issues are 
resolved in accordance with this process and the regulatory authority 
receives written documentation from the Service that all issues have 
been resolved. Like all provisions of proposed paragraph (e)(2), this 
provision is intended to ensure the protection of threatened and 
endangered species in accordance with the Endangered Species Act.
7. Section 780.19: What baseline information on hydrology, geology, and 
aquatic biology must I provide?
Proposed paragraph (a): General Requirements
    Proposed paragraph (a) would require that each permit application 
contain information on the hydrology, geology, and aquatic biology of 
the proposed permit and adjacent areas in sufficient detail to assist 
in preparing the determination of the probable hydrologic consequences 
of mining under 30 CFR 780.20, preparing the hydrologic reclamation 
plan under 30 CFR 780.22, preparing the surface-water and groundwater 
monitoring plans under 30 CFR 780.23, preparing the plans for 
monitoring the biological condition of streams under 30 CFR 780.23, 
demonstrating that all reclamation required by the regulatory program 
can be accomplished as required by 30 CFR 773.15(b), preparing the 
cumulative hydrologic impact assessment under 30 CFR 780.21, and 
determining whether the proposed operation has been designed to prevent 
material damage to the hydrologic balance outside the permit area as 
required by 30 CFR 773.15(e).
    Section 510(b)(3) of SMCRA \329\ specifies that the regulatory 
authority may not approve a permit application unless the regulatory 
authority has ``made an assessment of the probable cumulative impact of 
all anticipated mining in the area on the hydrologic balance specified 
in section 507(b).'' This assessment is commonly referred to as the 
CHIA. Section 507(b)(11) of SMCRA,\330\ the pertinent part of the SMCRA 
section referenced in the quote above, requires that each permit 
application include--
---------------------------------------------------------------------------

    \329\ 30 U.S.C. 1260(b)(3).
    \330\ 30 U.S.C. 1257(b)(11).

a determination of the probable hydrologic consequences of the 
mining and reclamation operations, both on and off the mine site, 
with respect to the hydrologic regime, quantity and quality of water 
in surface and ground water systems including the dissolved and 
suspended solids under seasonal flow conditions and the collection 
of sufficient data for the mine site and surrounding areas so that 
an assessment can be made by the regulatory authority of the 
probable cumulative impact of all anticipated mining in the area 
upon the hydrology of the area and particularly upon water 
---------------------------------------------------------------------------
availability.

    Section 510(b)(3) also specifies that the regulatory authority may 
not approve a permit unless the application affirmatively demonstrates 
and the regulatory authority finds in writing that the proposed 
operation ``has been designed to prevent material damage to the 
hydrologic balance outside the permit area.'' In addition, section 
510(b)(2) of SMCRA \331\ specifies that the regulatory authority may 
not approve a permit unless the application affirmatively demonstrates 
and the regulatory authority finds in writing that the ``applicant has 
demonstrated that reclamation as required by this Act and the State or 
Federal program can be accomplished under the reclamation plan 
contained in the permit application.''
---------------------------------------------------------------------------

    \331\ 30 U.S.C. 1260(b)(2).
---------------------------------------------------------------------------

    Without sound baseline information on surface-water and groundwater 
quality and quantity and the biological communities in streams, the 
regulatory authority cannot prepare an adequate CHIA or determine 
whether the proposed mining operation has been designed to prevent 
material damage to the hydrologic balance outside the permit area. A 
lack of adequate baseline data and accurate mining impact analyses 
based on that data likewise would impair the ability of the regulatory 
authority to make the finding required by 30 CFR 773.15(b) and section 
510(b)(2) of SMCRA \332\ concerning the feasibility of reclamation. 
Proposed 30 CFR 780.19 would refine and expand baseline data 
requirements for permit applications to promote more effective 
implementation of sections 507(b)(11) and 510(b)(3) of SMCRA \333\ and 
better protect streams, groundwater, and related environmental values.

Proposed Paragraph (b): Information on Groundwater
    Proposed paragraph (b)(1) would require that each permit 
application include information sufficient to document seasonal 
variations in the quality, quantity, and usage of groundwater, 
including all surface discharges, within the proposed permit and 
adjacent areas. Currently, this provision is part of existing 30 CFR 
780.21(b)(1).
    Proposed paragraph (b)(2) would require that the permit application 
include an assessment of the seasonal characteristics of any 
underground mine pool that is present within the proposed permit or 
adjacent areas unless the applicant demonstrates, and the regulatory 
authority finds, that the mine pool is not hydrologically connected to 
the proposed permit area. Proposed paragraph (b)(2) also would require 
that the determination of the probable hydrologic consequences of the 
proposed operation include a discussion of the effect of the proposed 
mining operation on any underground mine pools within the proposed 
permit and adjacent areas. In our experience, the mine pools associated 
with underground mines adjacent to, underlying, or overlying the 
proposed operation are not always properly or completely described, 
including the current or potential degree of hydrologic connection 
between the mine pool and the proposed operation. The level of detail 
and data collection needs to be sufficient for the reviewer to 
understand the complex interaction between the mine pools and the 
hydrology of the proposed permit and adjacent areas.
    Proposed paragraph (b)(3) would allow the regulatory authority to 
require the installation of properly-screened monitoring wells when 
necessary to obtain groundwater quality and quantity information 
sufficient to characterize seasonal variations. Properly-designed and 
constructed monitoring wells are essential to collection of reliable 
and scientifically-valid data, which section 517(b)(2) of SMCRA 
requires.

[[Page 44497]]

    Proposed paragraph (b)(4) would expand the list of parameters in 
existing 30 CFR 780.21(b)(1) that must be included in the description 
of groundwater quality. Proposed new parameters include major anions, 
major cations, the cation-anion balance, hot acidity,\334\ total 
alkalinity, pH, ammonia, arsenic, cadmium, copper, nitrogen, selenium, 
and zinc. Our rationale for adding these parameters is that a complete 
characterization of the prevailing premining hydrologic balance, 
including water chemistry, is necessary to fully assess the impacts of 
the proposed operations. The additional data also would facilitate 
quality assurance and quality control procedures. Finally, the 
additional baseline data may document existing water quality or other 
problems and thus provide the permittee with a defense against later 
assertions that it has caused adverse impacts to a stream with respect 
to those parameters.
---------------------------------------------------------------------------

    \334\ Hot acidity refers to the hot peroxide treatment titration 
method for determination of acidity.
---------------------------------------------------------------------------

    The proposed addition of selenium and a requirement for both total 
dissolved solids and specific conductance (rather than either total 
dissolved solids or specific conductance, as in the existing 
regulations) reflect concerns identified in scientific studies 
documenting the adverse impacts that elevated concentrations of those 
parameters have had on aquatic life in streams in the central 
Appalachian coalfields. Part II of this preamble summarizes some of 
those studies.
    Proposed paragraph (b)(5) is substantively identical to the 
groundwater quantity information requirements in the last sentence of 
existing 30 CFR 780.21(b)(1).
    Proposed paragraph (b)(6)(i) would require that the permit 
applicant establish monitoring wells (or equivalent monitoring points 
like springs and other direct surface discharges of groundwater) at a 
sufficient number of locations within the proposed permit and adjacent 
areas to determine groundwater quality, quantity, and movement in each 
aquifer above or immediately below the lowest coal seam to be mined. At 
a minimum, for each aquifer, we propose to require monitoring points 
upgradient and downgradient of the proposed permit area and within the 
proposed permit area to ensure collection of data sufficient to fully 
describe baseline groundwater conditions.
    Proposed paragraph (b)(6)(ii) would require that the permit 
applicant collect water samples from the locations identified in 
proposed paragraph (b)(6)(i) at equally-spaced monthly intervals for a 
minimum of 12 consecutive months to document seasonal variations in the 
quality of groundwater through a complete hydrologic cycle. Proposed 
paragraph (b)(6)(ii) also would require that the permit applicant 
analyze those samples for all parameters listed in proposed paragraph 
(b)(4) at the same frequency. Analysis of all listed parameters would 
establish a comprehensive baseline for groundwater quality.
    Proposed paragraph (b)(6)(iii) would require that the permit 
applicant take the measurements listed in proposed paragraph (b)(5) at 
each location identified in proposed paragraph (b)(6)(i) at equally 
spaced monthly intervals for a minimum of 12 consecutive months to 
document seasonal variations in groundwater levels and to establish a 
comprehensive baseline for groundwater availability.
    Currently, regulatory authorities require anywhere from as few as 
three samples (high, mean, and low base flow) to multiple years of 
sampling. Requiring a minimum of 12 consecutive, equally-spaced monthly 
samples would ensure that the baseline data collected would cover the 
entire water year.\335\ Under both our existing rules and the 1979 
rules, the regulatory authority could accept fewer than 12 months of 
data, provided that, as explained in the preamble to the 1979 rules, 
the maximum seasonal variation could be established by extrapolation 
from existing data collected within the same watershed or in a similar 
watershed through the use of modeling or other reasonable predictive 
tools.\336\ However, our past experience indicates that extrapolation 
is not a reliably accurate method to document and describe seasonal 
variation. Therefore, we now propose to require collection of actual 
data for the complete water year.
---------------------------------------------------------------------------

    \335\ The water year runs from October 1 through September 30.
    \336\ 44 FR 15034 (Mar. 13, 1979).
---------------------------------------------------------------------------

    Proposed paragraph (b)(6)(iv) would require that the regulatory 
authority extend the minimum baseline data collection period whenever 
data available from the National Oceanic and Atmospheric Administration 
or similar databases indicate that the region in which the proposed 
operation is located experienced severe drought (-3.0 or lower on the 
Palmer Drought Severity Index \337\) or abnormally high precipitation 
(3.0 or higher on the Palmer Drought Severity Index) during the initial 
baseline data collection period. The Palmer Drought Severity Index is a 
national index used to characterize climatic conditions across the 
country on a weekly frequency. During excessively wet periods, the 
seasonal concentrations of chemical constituents might be lower than 
normal because flows and water levels are higher. During severe drought 
periods, the concentrations of chemical constituents might be higher 
than normal because flows and water levels are lower. We propose to 
require that baseline data collection continue until the dataset 
includes 12 consecutive months without severe drought or abnormally 
high precipitation. Without this provision, the baseline data in the 
permit application would not be an accurate description of normal 
premining conditions.

Proposed Paragraph (c): Information on Surface Water
    Proposed paragraph (c)(1) would require that each permit 
application include information sufficient to document seasonal 
variation in surface-water quality, quantity, and usage within the 
proposed permit and adjacent areas. Currently, this provision is part 
of existing 30 CFR 780.21(b)(2).
    Proposed paragraph (c)(2) would expand the list of parameters in 
existing 30 CFR 780.21(b)(2) that must be included in the descriptions 
of surface water quality. Proposed new parameters include major anions, 
major cations, the cation-anion balance, hot acidity,\338\ total 
alkalinity, pH, ammonia, arsenic, cadmium, copper, nitrogen, selenium, 
and zinc. We also propose to require that the applicant include any 
additional parameters required by the agency implementing the NPDES 
program under section 402 of the Clean Water Act.\339\ Our rationale 
for adding these parameters is that a complete characterization of the 
prevailing premining hydrologic balance, including water chemistry, is 
necessary to fully assess the impacts of the proposed operations. The 
additional data also would facilitate quality assurance and quality 
control procedures. Finally, the additional baseline data may document 
existing water quality or other problems and thus provide the permittee 
with a defense against later assertions that it

[[Page 44498]]

has caused adverse impacts to a stream with respect to those 
parameters.

    The proposed addition of selenium and a requirement for both total 
dissolved solids and specific conductance (rather than just one or the 
other, as in the existing regulations) reflect concerns identified in 
scientific studies documenting the adverse impacts that elevated 
concentrations of those parameters have had on aquatic life in streams 
in the central Appalachian coalfields. Part II of this preamble 
summarizes some of those studies.
    Proposed paragraph (c)(3)(i) would require that the applicant 
provide baseline information on seasonal flow variations and peak-flow 
magnitude and frequency for all perennial, intermittent, and ephemeral 
streams and other surface-water discharges within the proposed permit 
and adjacent areas. This information is needed to prepare the 
determination of the probable hydrologic consequences of mining under 
proposed 30 CFR 780.20 and to prepare the surface-water runoff control 
plan that we propose to require under 30 CFR 780.29. Proposed paragraph 
(c)(3)(i) also would require that the applicant provide information on 
the extent of existing usage for existing uses and anticipated usage 
for all reasonably foreseeable uses. This information is needed to 
prepare the determination of the probable hydrologic consequences of 
mining and the CHIA and to establish permit-specific criteria for 
material damage to the hydrologic balance outside the permit area, 
consistent with our proposed definition of that term in 30 CFR 701.5.
    Proposed paragraph (c)(3)(ii) would require the use of generally-
accepted professional flow measurement techniques to ensure the 
accuracy of baseline flow data. The proposed rule would prohibit the 
use of subjective visual flow observations because of the inherent lack 
of precision in those observations and variations among observers.
    Proposed paragraph (c)(4)(i) would require that the permit 
applicant establish monitoring points at a sufficient number of 
locations within the proposed permit and adjacent areas to determine 
the quality and quantity of water in each stream within those areas. At 
a minimum, we propose to require monitoring points upgradient and 
downgradient of the proposed permit area in each perennial and 
intermittent stream within the proposed permit and adjacent areas, as 
well as in a representative number of ephemeral streams within the 
proposed permit area, to ensure collection of data sufficient to fully 
describe baseline surface water conditions. Ephemeral streams in the 
adjacent area are unlikely to be affected by mining, so we do not 
propose to require monitoring of those streams.
    Proposed paragraph (c)(4)(ii) would require that the permit 
applicant collect water samples from the locations identified in 
proposed paragraph (c)(4)(i) at equally-spaced monthly intervals for a 
minimum of 12 consecutive months to document seasonal variations in 
surface water quality through a complete hydrologic cycle. Proposed 
paragraph (c)(4)(ii) also would require that the permit applicant 
analyze those samples for all parameters listed in proposed paragraph 
(c)(2) at the same frequency. Analysis of all listed parameters would 
establish a comprehensive baseline for surface water quality.
    Proposed paragraph (c)(4)(iii) would require that the permit 
applicant take the measurements listed in proposed paragraph (c)(3) at 
each location identified in proposed paragraph (c)(4)(i) at equally 
spaced monthly intervals for a minimum of 12 consecutive months to 
document seasonal variations in streamflow and to establish a 
comprehensive baseline for streamflow and surface water availability.
    Currently, regulatory authorities require anywhere from as few as 
three samples (high, mean, and low base flow) to multiple years of 
sampling. Requiring a minimum of 12 consecutive, equally-spaced monthly 
samples would ensure that the baseline data collected would cover the 
entire water year.\340\ Under both our existing rules and the 1979 
rules, the regulatory authority could accept fewer than 12 months of 
data, provided that, as explained in the preamble to the 1979 rules, 
the maximum seasonal variation could be established by extrapolation 
from existing data collected within the same watershed or in a similar 
watershed through the use of modeling or other reasonable predictive 
tools.\341\ However, our past experience indicates that extrapolation 
is not a reliably accurate method to document and describe seasonal 
variation. Therefore, we now propose to require collection of actual 
data for the complete water year. In addition, our proposal is 
consistent with the approach now being taken by agencies responsible 
for implementing the Clean Water Act.
---------------------------------------------------------------------------

    \340\ The water year runs from October 1 through September 30.
    \341\ 44 FR 15034 (Mar. 13, 1979).
---------------------------------------------------------------------------

    Proposed paragraph (c)(4)(iv) would require that the regulatory 
authority extend the minimum baseline data collection period whenever 
data available from the National Oceanic and Atmospheric Administration 
or similar databases indicate that the region in which the proposed 
operation is located experienced severe drought (-3.0 or lower on the 
Palmer Drought Severity Index \342\) or abnormally high precipitation 
(3.0 or higher on the Palmer Drought Severity Index) during the initial 
baseline data collection period. The Palmer Drought Severity Index is a 
national index used to characterize climatic conditions across the 
country on a weekly frequency. During excessively wet periods, the 
seasonal concentrations of chemical constituents might be lower than 
normal because flows and water levels are higher. During severe drought 
periods, the concentrations of chemical constituents might be higher 
than normal because flows and water levels are lower. We propose to 
require that baseline data collection continue until the dataset 
includes 12 consecutive months without severe drought or abnormally 
high precipitation. Without this provision, the baseline data in the 
permit application would not be an accurate description of normal 
premining conditions.

---------------------------------------------------------------------------

    Proposed paragraph (c)(5) would require that the applicant provide 
records of precipitation amounts for the proposed permit area, using 
on-site self-recording devices. Precipitation records must be adequate 
to generate and calibrate a hydrologic model of the site, should the 
regulatory authority require such a model. This information is needed 
to prepare the PHC determination under proposed 30 CFR 780.20 and the 
surface-water runoff control plan required under proposed 30 CFR 
780.29.
    Proposed paragraph (c)(6) would require that the applicant identify 
and assess all perennial, intermittent, and ephemeral streams within 
the permit and adjacent areas. The assessment would include a 
description of the physical and hydraulic characteristics of the stream 
channel, as well as the biological condition of each stream, and the 
nature of vegetation within the riparian zone. For streams that appear 
on the list of impaired surface waters prepared under section 303(d) of 
the Clean Water Act,\343\ it also would

[[Page 44499]]

require identification of the stressors and associated total maximum 
daily loads, if applicable. Proposed paragraph (c)(6) would result in 
documentation of the premining physical and biological conditions of 
streams for purposes of evaluating the impacts of mining, establishing 
stream restoration standards, and establishing revegetation 
requirements for riparian corridors.

---------------------------------------------------------------------------

Proposed Paragraph (d): Additional Information for Discharges From 
Previous Coal Mining Operations
    Proposed paragraph (d) would require that the applicant collect and 
analyze a one-time sample of all existing discharges from previous 
mining operations within the proposed permit and adjacent areas during 
the low baseflow season. Both the applicant and the regulatory 
authority would use the results of these analyses to identify any 
additional parameters of concern. Data from previous mining operations 
also can be helpful in preparing the determination of the probable 
hydrologic consequences of mining and the CHIA. Hydrologic data from 
both reclaimed and unreclaimed minesites can be extremely valuable in 
predicting the impacts of future mining.
Proposed Paragraph (e): Biological Condition Information for Streams
    Proposed paragraph (e)(1) would require that each permit 
application include an assessment of the biological condition of each 
perennial and intermittent stream within the proposed permit and 
adjacent areas as well as an assessment of the biological condition of 
a representative sample of ephemeral streams within those areas. This 
requirement would not apply to a permit application for which the 
regulatory authority grants an exemption under proposed paragraph (h).
    Proposed paragraph (e)(2) would require that persons conducting the 
assessment use a multimetric bioassessment protocol approved by the 
state or tribal agency responsible for preparing the water quality 
inventory report required under section 305(b) of the Clean Water Act 
\344\ or other scientifically-valid multimetric bioassessment protocols 
used by agencies responsible for implementing the Clean Water Act. 
Multimetric indices include metrics such as species richness, 
complexity, and tolerance as well as trophic measures. They provide a 
quantitative comparison (often referred to as an index of biological or 
biotic integrity) of the ecological complexity of biological 
assemblages relative to a regionally-defined reference condition. 
However, we also propose to establish minimum standards that those 
protocols must meet. First, the bioassessment protocol must be based 
upon the measurement of an appropriate array of aquatic organisms, 
including benthic macroinvertebrates. Benthic macroinvertebrates are 
particularly useful for assessing the biological condition of the 
stream because certain species are highly sensitive to the presence of 
pollutants. Furthermore, we propose to require identification of 
benthic macroinvertebrates to the genus level because a bioassessment 
protocol that identifies macroinvertebrates only to the family level 
may not be capable of differentiating between pollution-tolerant and 
pollution-intolerant genera within the same family. On the other hand, 
a bioassessment protocol that identifies organisms to the species level 
may not be consistent with available indices of biological integrity.
---------------------------------------------------------------------------

    \344\ 33 U.S.C. 1315(b).
---------------------------------------------------------------------------

    Finally, proposed paragraph (e)(2) would require that the 
bioassessment protocol result in the calculation of index values for 
both habitat and macroinvertebrates and provide a correlation of index 
values to the capability of the stream to support designated uses under 
section 101(a) or 303(c) of the Clean Water Act, as well as any other 
existing or reasonably foreseeable uses. We seek comment on the 
effectiveness of using index scores from bioassessment protocols to 
ascertain impacts on existing, reasonably foreseeable, or designated 
uses. We also invite commenters to suggest other approaches that may be 
equally or more effective.
Proposed Paragraph (f): Geologic Information
    Proposed paragraph (f) is substantively identical to the existing 
rules at 30 CFR 780.22(b) through (d), except as discussed below. We 
propose to eliminate the provision in existing 30 CFR 780.22(b)(2)(ii) 
that allows the regulatory authority to waive the requirement that the 
permit application include analyses of each stratum in the geological 
column for alkalinity-producing materials. We also propose to eliminate 
the provision in existing 30 CFR 780.22(b)(2)(iii) that allows the 
regulatory authority to waive the requirement that the permit 
application include an analysis of the coal seam for pyritic sulfur. 
Both analyses are necessary for a complete acid-base accounting, 
assessment of the potential for acid mine drainage, and prediction of 
the total dissolved solids content of postmining discharges. In 
addition, this information is necessary to prepare an accurate 
determination of the probable hydrologic consequences of mining under 
proposed 30 CFR 780.20 and the cumulative hydrologic impact assessment 
under proposed 30 CFR 780.21. Finally, the information is necessary to 
assist the regulatory authority in determining whether reclamation is 
possible and whether the proposed operation will create a long-term 
postmining discharge requiring treatment.
    We invite comment on whether we should adopt provisions similar to 
proposed 30 CFR 777.13(b) to prescribe acceptable methodologies for the 
geochemical analyses required by proposed 30 CFR 780.19(f)(3)(ii) and 
(iii).
Proposed Paragraph (g): Cumulative Impact Area Information
    Proposed paragraph (g) is substantively identical to existing 30 
CFR 780.21(c), with the exception that we propose to clarify that the 
permit applicant may submit data and analyses from nearby mining 
operations if the site of those operations is representative of the 
proposed operations in terms of topography, hydrology, geology, 
geochemistry, and method of mining.
Proposed Paragraph (h): Exception for Operations That Avoid Streams
    Proposed paragraph (h) would allow a permit applicant to request 
that the regulatory authority waive the biological condition 
information requirements of proposed 30 CFR 780.19(e). The regulatory 
authority may approve the request only if it determines that the 
applicant has demonstrated that the proposed operation will not mine 
through or bury a perennial or intermittent stream; create a point-
source discharge to any perennial, intermittent, or ephemeral stream; 
or modify the baseflow of any perennial or intermittent stream.
Proposed Paragraph (i): Coordination With Clean Water Act Agencies
    Proposed paragraph (i) would require that SMCRA regulatory 
authorities consult with the agencies responsible for issuing permits, 
authorizations, and certifications under the Clean Water Act and make 
best efforts to minimize differences in baseline data collection points 
and parameters to the extent practicable and consistent with each 
agency's mission, statutory requirements, and implementing regulations. 
Coordination could reduce the overall regulatory impact to the 
industry, reduce the workload of

[[Page 44500]]

regulatory authorities, and expedite the permitting process. Applicants 
and permittees may use data already provided to or collected by a Clean 
Water Act agency to satisfy SMCRA requirements, provided that the data 
is reasonably current and of the type, scope, and quantity required for 
SMCRA purposes. Proposed paragraph (i) is consistent with the intent of 
section 713 of SMCRA,\345\ which, among other things, promotes 
coordination of regulatory activities under SMCRA and the Clean Water 
Act.
---------------------------------------------------------------------------

    \345\ 30 U.S.C. 1303.
---------------------------------------------------------------------------

Proposed Paragraph (j): Corroboration of Baseline Data
    Proposed paragraph (j) would require that the regulatory authority 
either corroborate a sample of the baseline information in each permit 
application or arrange for a third party to conduct the corroboration 
at the applicant's expense. Corroboration may include, but is not 
limited to, simultaneous sample collection and analysis, use of field 
verification measurements, or comparison of application data with 
application or monitoring data from adjacent operations. The existing 
regulations at 30 CFR 777.13 already require that the permit applicant 
document and describe the methods and persons collecting and analyzing 
technical data. We interpret the existing regulations as meaning that 
the regulatory authority has an obligation to monitor the accuracy and 
completeness of data collection and analyses for permit applications. 
Proposed paragraph (j) would make this responsibility explicit.
Proposed Paragraph (k): Permit Nullification for Inaccurate Information
    Proposed paragraph (k) specifies that a permit will be void from 
the date of issuance and have no legal effect if the permit issuance 
was based on substantially inaccurate baseline information. Under those 
circumstances, the proposed rule provides that the permittee must cease 
mining-related activities and immediately begin to reclaim the site. 
This measure would avoid or minimize the environmental harm that could 
result from initiation or continuation of an operation approved on the 
basis of substantially inaccurate data. We do not intend for this 
provision to apply in situations in which the application contains only 
minor omissions or errors. By ``substantially inaccurate,'' we mean 
situations such as missing or false chemical analyses of geologic 
strata or misrepresentation of data from another permit application as 
being collected from the proposed permit and adjacent areas. Adoption 
of proposed paragraph (k) would be in furtherance of section 102(a) of 
SMCRA,\346\ which provides that one of the purposes of the Act is to 
establish a nationwide program to protect society and the environment 
from the adverse effects of surface coal mining operations.

8. Section 780.20: How must I prepare the determination of the probable 
hydrologic consequences of my proposed operation (PHC determination)?
    Proposed paragraph (a) would revise the requirements concerning 
preparation of the determination of the probable hydrologic 
consequences of mining in existing 30 CFR 780.21(f)(1) through (f)(3) 
by adding a requirement to consider the impacts of the proposed 
operation on the biological condition of perennial, intermittent, and 
ephemeral streams located within the proposed permit and adjacent 
areas, not just on the quantity and quality of surface water and 
groundwater as in the existing rule. Proposed paragraph (a)(1) would 
replace the requirement in existing 30 CFR 780.21(f)(3)(i) for a 
finding on whether the proposed operation may cause adverse impacts to 
the hydrologic balance with a requirement for a finding on whether the 
proposed operation may cause material damage to the hydrologic balance 
outside the permit area. These proposed changes would more closely 
tailor the PHC determination to both the definition of ``material 
damage to the hydrologic balance outside the permit area'' that we 
propose to add to 30 CFR 701.5 and the existing finding that the 
regulatory authority must make before approving a permit application 
under 30 CFR 773.15(e), which, in relevant part, requires a 
determination that the proposed operation has been designed to prevent 
material damage to the hydrologic balance outside the permit area.
    Proposed paragraph (a)(4) would require a finding on whether the 
proposed operation would either intercept or create aquifers in surface 
mine spoil or underground mine voids. Surface mining frequently results 
in the formation of a new aquifer in spoil that is placed in either the 
backfill or an excess spoil fill. This aquifer may have substantially 
different quality and quantity characteristics than water found in 
undisturbed overburden strata. Underground mine voids can store large 
volumes of water in what are commonly known as mine pools. The storage 
volume and discharge rates of these pools may be orders of magnitude 
larger than those associated with aquifers in surface mine spoil 
because mine pools typically collect water from a much larger area than 
do surface mine spoil aquifers. Discharges from underground mine pools 
are frequently of relatively high volume because their recharge rate 
averages 0.47 gallons per minute per acre of mine voids.\347\

Formation by Well Dewatering. Special Report of Research, The 
Pennsylvania State University, 73 p.
---------------------------------------------------------------------------

    The quantity and quality of the groundwater that recharges the mine 
pool from overlying and underlying rock strata can significantly 
influence postmining water quality.\348\ These mine pool aquifers may 
discharge directly to the land surface or to groundwater systems 
downgradient of the aquifer. The PHC determination must consider the 
timing, quality, quantity, and location of these discharges to 
adequately assess the probable impacts of the proposed operation on the 
hydrologic balance. The new finding also would require evaluation of 
the impacts of any temporary or permanent dewatering of aquifers, 
including underground mine pools, on the hydrologic balance.

Mines, in the Proceedings of the Twenty-Fourth West Virginia Surface 
Mine Drainage Task Force Symposium, Morgantown, WV, 54 pp.
---------------------------------------------------------------------------

    Proposed paragraph (a)(5) would expand the finding in existing 30 
CFR 780.21(f)(3)(iv) concerning what impact the proposed operation 
would have on specific water quality parameters to include the 
parameters for which baseline information would be required under 
proposed 30 CFR 780.19(b) and (c). Furthermore, we propose to add 
requirements in paragraph (a)(5) for findings on what impact the 
proposed operation would have on precipitation runoff patterns and 
characteristics; seasonal variations in streamflow; the magnitude and 
frequency of peak flows in perennial, intermittent, and ephemeral 
streams within the proposed permit and adjacent areas; and the 
biological condition of those streams. Finally, we propose to add a 
requirement in paragraph (a)(5)(iv) for a finding about the impact that 
any diversion of surface or subsurface flows to underground mine 
workings or any changes in watershed size as a result of the postmining 
surface configuration would have on the availability of surface water 
and groundwater. The changes in proposed paragraph (a)(5)

[[Page 44501]]

would improve the comprehensiveness and predictive accuracy of the PHC 
determination. They also would provide a more scientifically sound 
basis for development of the CHIA required by proposed 30 CFR 780.21 
and the hydrologic reclamation plan required by proposed 30 CFR 780.22.
    Proposed paragraph (b) is substantively identical to existing 30 
CFR 780.21(b)(3), with the exception that we propose to expand the 
conditions under which the regulatory authority may request that the 
applicant submit supplemental information to include those situations 
in which the PHC determination indicates that the proposed operation 
may result in adverse impacts to the biological condition of perennial 
or intermittent streams within the proposed permit area or the adjacent 
area. We also propose to clarify that the regulatory authority may 
request additional geochemical analyses of overburden materials and 
information concerning underground mine pools and their impacts. The 
new provisions are necessary to ensure that the PHC determination is 
sufficiently comprehensive to support development of the hydrologic 
reclamation plan required by 30 CFR 780.22 and the CHIA required by 30 
CFR 780.21.
    Proposed paragraph (c)(1) is substantively identical to existing 30 
CFR 780.21(f)(4), which requires that the regulatory authority 
determine whether a new or updated PHC determination is needed as part 
of the process of evaluating permit revision applications. We propose 
to add paragraph (c)(2) to clarify that the applicant must prepare a 
new or updated PHC determination whenever a regulatory authority review 
finds that one is needed.
9. Section 780.21: What requirements apply to preparation and review of 
the cumulative hydrologic impact assessment (CHIA)?
    Our existing regulations contain very few standards or criteria for 
preparation of the CHIA. Those regulations, which are located at 30 CFR 
780.21(g)(1), provide that the regulatory authority must prepare an 
assessment of the probable cumulative hydrologic impacts of the 
proposed operation and all anticipated mining upon surface-water and 
groundwater systems in the cumulative impact area. The regulations 
further state that the assessment must be sufficient to determine, for 
purposes of permit approval, whether the proposed operation has been 
designed to prevent material damage to the hydrologic balance outside 
the permit area. The lack of standards or content requirements for the 
CHIA, coupled with the lack of a definition of material damage to the 
hydrologic balance, is an impediment to stream protection under SMCRA 
because there are no objective criteria to apply.
    We propose to remedy that problem, in part, by establishing more 
detailed content requirements for the CHIA, based on our experience as 
the regulatory authority in Tennessee and on Indian lands and on our 
experience in evaluating the implementation of state regulatory 
programs. Our proposed requirements would improve implementation of 
sections 507(b)(11) and 510(b)(3) of SMCRA,\349\ which require that the 
regulatory authority prepare a CHIA and provide that the regulatory 
authority may not approve a permit application unless the application 
affirmatively demonstrates, and the regulatory authority finds in 
writing, that the proposed operation has been designed to prevent 
material damage to the hydrologic balance outside the permit area. 
Section 201(c)(2) of SMCRA \350\ directs the Secretary, acting through 
OSMRE, to ``publish such rules and regulations as may be necessary to 
carry out the purposes and provisions of the Act.'' This provision 
establishes statutory authority for the enhanced CHIA regulations in 
this proposed rule. The more detailed CHIA content requirements that we 
propose to adopt are prudent measures to ensure that the CHIA is 
adequate to prevent the approval or renewal of permits that would 
result in material damage to the hydrologic balance outside the permit 
area.

    \350\ 30 U.S.C. 1211(c)(2).
---------------------------------------------------------------------------

    Proposed paragraph (a)(1) is substantively identical to existing 30 
CFR 780.21(g)(1), with the exception that we propose to clarify that 
the CHIA must be in writing. We also propose to remove the sentence 
stating that the regulatory authority may allow the permit applicant to 
submit data and analyses relevant to the CHIA with the application. 
This sentence that we propose to delete is unnecessary because it is 
inherently true, whether stated or not. In addition, proposed paragraph 
(a)(3) effectively replaces this sentence.
    Proposed paragraph (a)(2) would provide that, in preparing the 
CHIA, the regulatory authority must consider relevant information on 
file for other mining operations located within the cumulative impact 
area or in similar watersheds. This provision is intended to ensure 
that the regulatory authority considers all available information when 
preparing the CHIA.
    Proposed paragraph (a)(3) would provide that the regulatory 
authority may not approve a permit application until it receives the 
hydrologic, geologic, and biological information needed to prepare the 
CHIA, either from other federal and state agencies or from the 
applicant. This provision is consistent with similar language in the 
provisos at the end of section 507(b)(11) of SMCRA.\351\
---------------------------------------------------------------------------

    \351\ 30 U.S.C. 1257(b)(11).

    Proposed paragraph (b) would establish detailed content 
requirements for the CHIA to ensure that the assessment is sufficiently 
comprehensive to support the finding that the regulatory authority must 
make under section 510(b)(3) of SMCRA \352\ and 30 CFR 773.15(e) 
regarding whether the operation has been designed to prevent material 
damage to the hydrologic balance outside the permit area. The new 
requirements correspond to elements of the proposed definition of 
``material damage to the hydrologic balance outside the permit area'' 
in 30 CFR 701.5. By requiring the development of permit-specific, 
numerical material damage criteria, they also would facilitate 
implementation of the prohibition in section 510(b)(3) of SMCRA and 30 
CFR 773.15(e) on approval of a permit application unless the CHIA 
demonstrates that the proposed operation has been designed to prevent 
material damage to the hydrologic balance outside the permit area.
---------------------------------------------------------------------------

    \352\ 30 U.S.C. 1260(b)(3).
---------------------------------------------------------------------------

    Proposed paragraph (b)(1) would require that the CHIA contain a map 
of the cumulative impact area. The boundaries of this area may differ 
for surface water and groundwater, in which case proposed paragraph 
(b)(1)(i) would require that the map identify and display those 
differences. Proposed paragraphs (b)(1)(ii) through (iv) would require 
that the map identify the locations of all previous, current, and 
anticipated surface and underground mining, the locations of all 
baseline data collection sites under proposed 30 CFR 780.19, and 
designated uses of surface water under section 101(a) or 303(c) of the 
Clean Water Act.
    Proposed paragraph (b)(2) would require that the CHIA contain a 
description of all previous, existing, and anticipated mining within 
the cumulative impact area, including, at a minimum, the coal seam or 
seams mined, the extent of mining, and the reclamation status of each 
operation.

[[Page 44502]]

    Proposed paragraph (b)(3) would require that the CHIA contain a 
description of the baseline hydrologic information collected from the 
proposed permit and adjacent areas under proposed 30 CFR 780.19. This 
description would include the quality and quantity of surface water and 
groundwater and seasonal variations therein; quantitative information 
about existing usage of surface water and groundwater, as well as 
information defining the quality of water required for each existing 
and reasonably foreseeable use of groundwater and surface water and 
each designated use of surface water under section 101(a) or 303(c) of 
the Clean Water Act; a description and map of the local and regional 
groundwater systems; and the biological condition of perennial, 
intermittent, and ephemeral streams within the proposed permit and 
adjacent areas. The requirements of proposed paragraph (b)(3) would not 
apply to the entire cumulative impact area.
    Proposed paragraph (b)(4) would require that the CHIA contain a 
discussion of any potential concerns identified in the PHC 
determination prepared under proposed 30 CFR 780.20 and how those 
concerns have been or will be resolved.
    Proposed paragraph (b)(5) would require that the CHIA contain a 
qualitative and quantitative assessment of how all anticipated surface 
and underground mining may impact water quality in surface water and 
groundwater in the cumulative impact area, expressed in terms of each 
baseline parameter identified under 30 CFR 780.19.
    Proposed paragraph (b)(6) would require that the CHIA contain 
criteria defining material damage to the hydrologic balance outside the 
permit area on a site-specific basis and that these numerical criteria 
be incorporated into the permit to ensure that they are enforceable. 
Proposed paragraphs (b)(6)(i) through (iii) would require that the 
criteria be expressed in numerical terms for each parameter of concern, 
that they take into consideration the biological requirements of any 
species listed as threatened or endangered under the Endangered Species 
Act when those species or designated critical habitat are present 
within the cumulative impact area, and that they identify the portion 
of the cumulative impact area to which the criteria apply and the 
locations at which impacts will be monitored. The regulatory authority 
may establish different criteria for subareas within the cumulative 
impact area when appropriate. Water quality standards established under 
the Clean Water Act or in the NPDES permit for the operation might 
suffice for some parameters of concern, but NPDES permits do not 
address cumulative impacts and are not necessarily structured to 
prevent material damage to the hydrologic balance outside the permit 
area.
    We invite comment on whether the rule also should require that the 
regulatory authority establish lower corrective action thresholds to 
identify the point at which the permittee must take action to minimize 
the potential that adverse trends will continue and ultimately cause 
material damage to the hydrologic balance outside the permit area. In 
particular, we are interested in whether corrective action thresholds 
would be both more effective and more efficient in preventing material 
damage to the hydrologic balance outside the permit area, as required 
by SMCRA, and in avoiding designation of streams as impaired under 
section 303(d) of the Clean Water Act.\353\
---------------------------------------------------------------------------

    \353\ 33 U.S.C. 1313(d).
---------------------------------------------------------------------------

    Proposed paragraph (b)(7) would require an assessment of how all 
anticipated surface and underground mining may affect groundwater 
movement and availability within the cumulative impact area. This 
information is important in the determination of whether adverse 
impacts on groundwater would be severe enough to result in material 
damage to the hydrologic balance outside the permit area.
    Proposed paragraph (b)(8) would require an evaluation of whether 
the CHIA will support a finding that the operation has been designed to 
prevent material damage to the hydrologic balance outside the permit 
area, as required by 30 CFR 773.15(e) and section 510(b)(3) of 
SMCRA.\354\ This evaluation would have to contain supporting data and 
analyses. Proposed paragraph (b)(8) also would require that the CHIA 
include certain documented determinations as a prerequisite for a 
finding that the operation has been designed to prevent material damage 
to the hydrologic balance outside the permit area.
---------------------------------------------------------------------------

    \354\ 30 U.S.C. 1260(b)(3).
---------------------------------------------------------------------------

    Proposed paragraph (b)(8)(i) would require a determination that, 
during all phases of mining and reclamation and at all times of the 
year, variations in streamflow and groundwater availability resulting 
from the operation, as well as variations in the amount and 
concentration of parameters of concern in discharges from the operation 
to groundwater and surface water, would not--
     Result in conversion of a perennial or intermittent stream 
to an ephemeral stream or conversion of a perennial stream to an 
intermittent stream. Conversion of an intermittent stream to a 
perennial stream or conversion of an ephemeral stream to an 
intermittent or perennial stream may be acceptable, provided the 
conversion would not disrupt or preclude any existing, reasonably 
foreseeable, or designated use of the stream under section 101(a) or 
303(c) of the Clean Water Act and would not adversely impact threatened 
or endangered species or designated critical habitat in violation of 
the Endangered Species Act. We also are considering replacement of 
``would not adversely impact threatened or endangered species or 
designated critical habitat in violation of the Endangered Species 
Act'' with ``would not jeopardize the continued existence of threatened 
or endangered species or result in the destruction or adverse 
modification of designated critical habitat in violation of the 
Endangered Species Act.'' The second alternative would parallel the 
language of existing and proposed 30 CFR 816.97(b) and 817.97(b).
     Result in an exceedance of applicable water quality 
standards in any stream located outside the permit area.
     Disrupt or preclude any existing or reasonably foreseeable 
use of surface water outside the permit area or any designated use of 
surface water under section 101(a) or 303(c) of the Clean Water Act 
\355\ outside the permit area, except as provided in water supply 
replacement provisions of proposed 30 CFR 780.22(b) and 816.40.

    \355\ 33 U.S.C. 1251(a) and 1313(c).
---------------------------------------------------------------------------

    Proposed paragraph (b)(8)(ii) would require a determination that 
the operation has been designed to ensure that neither the mining 
operation nor the final configuration of the reclaimed area will result 
in changes in the size or frequency of peak flows from precipitation 
events or thaws that would cause an increase in damage from flooding, 
when compared with premining conditions.
    Proposed paragraph (b)(8)(iii) would require a determination that 
perennial and intermittent streams located outside the permit area but 
within the cumulative impact area would continue to have sufficient 
baseflow and recharge capacity to maintain their premining flow regime 
both during and after mining and reclamation. In other words, the 
regulatory authority must find that

[[Page 44503]]

perennial stream segments will retain perennial flows and intermittent 
stream segments will retain intermittent flows during and after mining 
and reclamation. Conversion of an intermittent stream to a perennial 
stream or conversion of an ephemeral stream to an intermittent or 
perennial stream may be acceptable, provided the conversion would not 
disrupt or preclude any existing, reasonably foreseeable, or designated 
use of the stream under section 101(a) or 303(c) of the Clean Water Act 
and would not adversely impact threatened or endangered species or 
designated critical habitat in violation of the Endangered Species Act. 
We also are considering replacement of ``would not adversely impact 
threatened or endangered species or designated critical habitat in 
violation of the Endangered Species Act'' with ``would not jeopardize 
the continued existence of threatened or endangered species or result 
in the destruction or adverse modification of designated critical 
habitat in violation of the Endangered Species Act.'' The second 
alternative would parallel the language of existing and proposed 30 CFR 
816.97(b) and 817.97(b).
    Proposed paragraph (b)(8)(iv) would require a determination that 
the operation has been designed to protect the quantity and quality of 
water in any aquifer that significantly ensures the prevailing 
hydrologic balance.
    Proposed paragraph (c)(1) would require that the regulatory 
authority review each application for a significant permit revision to 
determine whether a new or updated CHIA is needed. This paragraph is 
similar to existing 30 CFR 780.21(g)(2), except that we propose to add 
a requirement that the regulatory authority document the review, 
including the analysis and conclusions, together with the rationale for 
the conclusions, in writing. In addition, we propose to require this 
review only for applications for significant permit revisions, not for 
all applications for any type of permit revisions as under the existing 
rule. We are not aware of any situation in which a non-significant 
permit revision application has required an update of the CHIA under 
the existing rules. Therefore, conducting this review of non-
significant permit revision applications is not a meaningful or 
productive use of regulatory authority resources.
    Proposed paragraph (c)(2) would add a requirement that the 
regulatory authority reevaluate the CHIA during the permit renewal 
process or every 5 years, whichever is more frequent, to determine 
whether the CHIA remains accurate and whether the material damage 
criteria in the CHIA and the permit are adequate to ensure that 
material damage to the hydrologic balance outside the permit area will 
not occur. This evaluation must include a review of all water 
monitoring data from both the operation in question and all coal mining 
operations within the cumulative impact area. We invite comment on 
whether this 5-year review frequency for water monitoring data is 
adequate to detect adverse trends in a timely manner or whether more 
frequent reviews, such as during midterm permit review, should be 
required. In addition, we invite comment on whether the permittee also 
should be required to conduct this review.
    Proposed paragraph (c)(3) would require preparation of a new or 
updated CHIA whenever the regulatory authority finds that one is needed 
based on the evaluation required by proposed paragraph (c)(2). Proposed 
paragraphs (c)(2) and (c)(3) are logical extensions of the finding that 
the regulatory authority must make under section 510(b)(3) of SMCRA 
\356\ and 30 CFR 773.15(e) regarding whether the operation has been 
designed to prevent material damage to the hydrologic balance outside 
the permit area.

    \356\ 30 U.S.C. 1260(b)(3).
---------------------------------------------------------------------------

10. Section 780.22: What information must I include in the hydrologic 
reclamation plan and what information must I provide on alternative 
water resources?
    Proposed paragraph (a) would be substantively identical to the 
hydrologic reclamation plan requirements in existing 30 CFR 780.21(h), 
except as discussed below. Proposed paragraph (a)(2)(v) would replace 
the existing requirement for measures to avoid acid or toxic drainage 
with a requirement for preventive and remedial measures to avoid acid 
or toxic discharges to surface water and to avoid (or, if avoidance is 
not possible, minimize) degradation of groundwater. The new language 
reflects the nature of the surface mining process, which typically 
converts solid rock to highly-fragmented spoil, thus altering 
groundwater composition and quality.
    Proposed paragraph (a)(3) would require that the hydrologic 
reclamation plan address the impacts of any transfers of water among 
active and abandoned mines within the proposed permit and adjacent 
areas. The transfer of water between mines, whether intentional through 
direct connections or unintentional through leakage, can have 
substantial impacts on the availability, quality, and distribution of 
groundwater and surface water in the permit and adjacent areas, which 
in turn may have a substantial impact on users of groundwater and 
surface water. For example, a reduction in baseflow of a stream would 
reduce the assimilative capacity of the stream. In addition, increases 
in the hydrostatic head elevations of underground mine pools might 
cause blowouts or landslides or have other adverse impacts on land and 
water resources.
    Proposed paragraph (a)(4) would add a requirement for a description 
of the steps that the permittee will take during mining and reclamation 
through final bond release to protect and enhance aquatic life and 
related environmental values to the extent possible using the best 
technology currently available. This requirement would more completely 
implement section 515(b)(24) of SMCRA,\357\ which provides that surface 
coal mining and reclamation operations must use the best technology 
currently available to minimize disturbances and adverse impacts to 
fish, wildlife, and related environmental values to the extent possible 
and enhance those resources where practicable.
---------------------------------------------------------------------------

    \357\ 30 U.S.C. 1265(b)(24).
---------------------------------------------------------------------------

    Proposed paragraph (b) would replace and expand the alternative 
water source information required by existing 30 CFR 780.21(e) if the 
proposed operation may result in contamination, diminution, or 
interruption of a protected water supply. Proposed paragraph (b)(1) 
would require that the applicant identify alternative water sources 
that are available, feasible to develop, and suitable in quality and 
sufficient in quantity to support premining uses and approved 
postmining land uses. Proposed paragraph (b)(2) would prohibit any 
mining that would contaminate, diminish, or interrupt a protected water 
supply if the applicant is unable to identify any suitable alternative 
water sources. These provisions are intended to prevent situations in 
which high-quality water from a spring is replaced with well water that 
requires substantial treatment.
    When a suitable alternative water source is available, proposed 
paragraph (b)(3) would require that the permittee develop and install 
the alternative water supply on a permanent basis before adversely 
affecting an existing water supply protected under proposed 30 CFR 
816.40. This provision would not apply if the permittee demonstrates, 
and the regulatory authority finds, that the proposed operation also 
would adversely affect the replacement supply.

[[Page 44504]]

In that case, the proposed rule would require that the permittee 
provide a temporary replacement water supply until it is safe to 
install the permanent replacement water supply.
    Finally, proposed paragraph (b)(4) would require a description of 
how the applicant would provide both temporary and permanent 
replacements for any unexpected losses of protected water supplies in 
accordance with the timeframes and other requirements of proposed 30 
CFR 816.40.
    Proposed paragraph (b) is intended to more completely implement the 
water supply replacement requirements of sections 717(b) and 720(a)(2) 
of SMCRA.\358\

11. Section 780.23: What information must I include in plans for the 
monitoring of groundwater, surface water, and the biological condition 
of streams during and after mining?
    Paragraphs (b)(1) and (2) of section 517 of SMCRA \359\ provide 
authority for the adoption of regulations establishing monitoring 
requirements for surface coal mining and reclamation operations. Among 
other things, paragraph (b)(1) provides that ``the regulatory authority 
shall require any permittee to . . . install, use, and maintain any 
necessary monitoring equipment or methods [and] evaluate results in 
accordance with such methods, at such locations, intervals, and in such 
manner as a regulatory authority shall prescribe.'' Paragraph (b)(2) 
includes the following additional provisions:
---------------------------------------------------------------------------

    \359\ 30 U.S.C. 1267(b)(1) and (2).

    [F]or those surface coal mining and reclamation operations which 
remove or disturb strata that serve as aquifers which significantly 
insure the hydrologic balance of water use either on or off the 
mining site, the regulatory authority shall specify those--
    (A) monitoring sites to record the quantity and quality of 
surface drainage above and below the minesite as well as in the 
potential zone of influence;
    (B) monitoring sites to record level, amount, and samples of 
ground water and aquifers potentially affected by the mining and 
also directly below the lowermost (deepest) coal seam to be mined;
    (C) records of well logs and borehole data to be maintained; and
    (D) monitoring sites to record precipitation.
    The monitoring data collection and analysis required by this 
section shall be conducted according to standards and procedures set 
forth by the regulatory authority in order to assure their 
reliability and validity.

    Proposed 30 CFR 780.23 would establish more detailed requirements 
for groundwater and surface-water monitoring plans than those that 
appear in existing 30 CFR 780.21(i) and (j). Thus, they would more 
completely implement the statutory provisions described and quoted 
above. Furthermore, our proposed enhanced monitoring requirements are 
intended to ensure that, as required by section 515(b)(24) of 
SMCRA,\360\ surface coal mining and reclamation operations are 
conducted so as to minimize disturbances to and adverse impacts on 
fish, wildlife, and related environmental values to the extent possible 
using the best technology currently available.
---------------------------------------------------------------------------

    \360\ 30 U.S.C. 1265(b)(24).
---------------------------------------------------------------------------

    Finally, our proposed enhanced monitoring requirements would be 
consistent with both the more comprehensive baseline information that 
we propose to require in 30 CFR 780.19 and the definition of ``material 
damage to the hydrologic balance outside the permit area'' that we 
propose to adopt in 30 CFR 701.5. Comprehensive baseline information 
and monitoring are critical to evaluating the impact of the mining 
operation on the hydrologic balance, which in turn is essential to 
preventing the occurrence of material damage to the hydrologic balance 
outside the permit area, consistent with section 510(b)(3) of 
SMCRA.\361\
---------------------------------------------------------------------------

    \361\ 30 U.S.C. 1260(b)(3).
---------------------------------------------------------------------------

Proposed Paragraphs (a): Groundwater Monitoring Plan
    Proposed paragraph (a) would include the groundwater monitoring 
plan requirements in existing 30 CFR 780.21(i). We propose to revise 
those requirements by adding more specific minimum requirements for the 
groundwater monitoring plan to ensure that the plan is adequate to 
evaluate the impacts of the mining operation on groundwater in the 
proposed permit and adjacent areas and to identify adverse trends in 
sufficient time to initiate corrective action to prevent the operation 
from causing material damage to the hydrologic balance outside the 
permit area. The following discussion highlights the more significant 
elements of proposed paragraph (a).
    Proposed paragraph (a)(1)(iii)(A) would require that each 
groundwater monitoring plan include monitoring wells (or equivalent 
monitoring points with direct groundwater discharges, such as springs) 
located upgradient and downgradient of the proposed operation to 
facilitate identification of potential mining-related changes in 
groundwater quantity or quality and to assist in an evaluation of 
whether any downgradient changes are the result of the mining and 
reclamation activities. The proposed rule would require separate wells 
for each aquifer above or immediately below the lowest coal seam to be 
mined. This provision would ensure identification of impacts on each 
aquifer, consistent with section 517(b)(2)(B) of SMCRA, which requires 
monitoring of ``aquifers potentially affected by the mining and also 
directly below the lowermost (deepest) coal seam to be mined.''
    Proposed paragraph (a)(1)(iii)(B) would require placement of 
monitoring wells in backfilled portions of the permit area after 
backfilling and grading of all or a portion of the permit area is 
completed. The purpose of these wells is to identify how infiltration 
through the spoil may alter groundwater levels and quality. The 
proposed rule would allow the regulatory authority to waive placement 
of monitoring wells in the backfilled area if it finds that wells in 
the backfilled area are not necessary to determine or predict the 
future impact of the mining operation on groundwater quality.
    Finally, to monitor impacts on underground mine pools, proposed 
paragraph (a)(1)(iii)(C) would require placement of monitoring wells in 
any existing underground mine workings that would have a direct 
hydrological connection to the proposed operation. These mine pools may 
serve as municipal, industrial, or residential water supplies. In 
addition, sudden, unplanned releases of the water in those mine pools 
can result in flooding damage or adverse impacts on receiving streams.
    Proposed paragraph (a)(1)(iv) would require that the plan describe 
how the monitoring data will be used to determine the impacts of the 
operation upon the hydrologic balance and the biological condition of 
perennial and intermittent streams within the permit and adjacent 
areas, as well as to prevent material damage to the hydrologic balance 
outside the permit area.
    Proposed paragraph (a)(1)(v) would require that the plan describe 
how monitoring practices will comply with the sampling, analysis, and 
reporting requirements of proposed 30 CFR 777.13(a) and (b) to ensure 
that samples are collected and analyzed in a legally and scientifically 
valid manner. Proposed paragraph (a)(1)(v) is consistent with the 
requirement in the text after section 517(b)(2)(D) of SMCRA \362\ that 
the regulatory authority set forth standards and procedures for 
monitoring data collection and analysis

[[Page 44505]]

to assure the reliability and validity of the data.
---------------------------------------------------------------------------

    \362\ 30 U.S.C. 1267(b)(2)(D).
---------------------------------------------------------------------------

    Proposed paragraph (a)(2)(i) would require that the groundwater 
monitoring plan provide for the monitoring of parameters that could be 
affected by the proposed operation if those parameters relate to the 
findings and predictions in the PHC determination prepared under 30 CFR 
780.20, the biological condition of perennial and intermittent streams 
and other surface-water bodies that receive discharges from groundwater 
within the proposed permit and adjacent areas, the suitability of the 
groundwater for existing and reasonably foreseeable uses, and the 
suitability of the groundwater to support the premining and postmining 
land uses. Monitoring of these parameters would assist the permittee 
and regulatory authority in preventing material damage to the 
hydrologic balance outside the permit area and in determining 
compliance with the water supply protection and postmining land use 
requirements of SMCRA and its implementing regulations.
    Proposed paragraph (a)(2)(ii) would require quarterly monitoring of 
14 specific parameters, including, among others, selenium and the 
minimum water-quality parameters required by existing 30 CFR 
780.21(i)(1) (pH, total iron, total manganese, and total dissolved 
solids or specific conductance). As summarized in Part II of this 
preamble, selenium can have deleterious effects upon fish and human 
health. In addition, this proposed paragraph would require quarterly 
monitoring of major anions (including, at a minimum, bicarbonate, 
chloride, and sulfate), major cations (including, at a minimum, 
calcium, magnesium, potassium, and sodium), and the cation-anion 
balance. As summarized in Part II of this preamble, these anions and 
cations form salts that can alter water chemistry in a manner that 
sometimes has a substantial adverse impact on aquatic life. With 
respect to water quantity, proposed paragraph (a)(2)(ii) would require 
quarterly measurement of water levels, discharge rates, or yield rates. 
Existing 30 CFR 780.21(i) only requires monitoring of water levels, 
which may not be sufficient to fully evaluate groundwater quantity and 
availability in all cases. Finally, proposed paragraph (a)(2)(ii) would 
require quarterly monitoring of certain metals (if present in 
discharges from prior underground mines) and any other parameters of 
local significance, as determined by the regulatory authority based 
upon the information collected and the analyses conducted under 
proposed 30 CFR 780.19 through 780.21.
    Proposed paragraph (a)(3) would require that the regulatory 
authority reconsider the adequacy of the groundwater monitoring plan at 
two points during the permit application review process. The first 
reconsideration would occur after the regulatory authority completes 
the technical review of the application. At that point, the regulatory 
authority may require that the permit applicant revise the plan to 
increase the frequency of monitoring, to require monitoring of 
additional parameters, or to require monitoring at additional 
locations, if the additional requirements would contribute to 
protection of the hydrologic balance. The second reconsideration would 
occur after preparation of the CHIA under proposed 30 CFR 780.21. At 
that point, the regulatory authority would be responsible for ensuring 
that the groundwater monitoring plan requires monitoring of all 
parameters for which the CHIA establishes material damage criteria; 
i.e., all parameters of concern. These reconsiderations are intended to 
ensure that the monitoring plans are designed to provide sufficiently 
comprehensive monitoring data to enable both the permittee and the 
regulatory authority to identify any adverse impacts on groundwater in 
time to take corrective action to prevent material damage to the 
hydrologic balance outside the permit area.
    Finally, proposed paragraph (a)(4) would modify the provision in 
existing 30 CFR 780.21(i)(2) that authorizes a groundwater-monitoring 
exception for any water-bearing stratum that does not serve as an 
aquifer that significantly ensures the hydrologic balance within the 
cumulative impact area. Specifically, proposed paragraph (a)(4) would 
allow a groundwater-monitoring exception for a water-bearing stratum 
that does not serve as an aquifer that significantly ensures the 
hydrologic balance within the cumulative impact area only if that 
stratum has no existing or foreseeable use for agricultural or other 
human purposes or for fish and wildlife purposes. The addition of this 
requirement would more fully implement the environmental protection 
purposes set forth in sections 102(a) and (d) of SMCRA.\363\ We 
recognize that the proposed new criterion does not appear in section 
517(b)(2) of SMCRA.\364\ However, addition of the new criterion is 
appropriate because use of water for agricultural or fish and wildlife 
purposes impacts land use capability and productivity and would assist 
in the implementation of the postmining land use requirements of 
section 515(b)(2) of SMCRA \365\ and the fish and wildlife protection 
and enhancement requirements of section 515(b)(24) of SMCRA.\366\

Proposed Paragraph (b): Surface-Water Monitoring Plan
    Proposed paragraph (b) would include the surface-water monitoring 
plan requirements in existing 30 CFR 780.21(j). We propose to revise 
those requirements by adding more specific minimum requirements for the 
surface-water monitoring plan to ensure that the plan is adequate to 
evaluate the impacts of the mining operation on streams and other 
surface-water bodies in the proposed permit and adjacent areas and to 
identify adverse trends in sufficient time to initiate corrective 
action to prevent the operation from causing material damage to the 
hydrologic balance outside the permit area. The following discussion 
highlights the more significant elements of proposed paragraph (b).
    Proposed paragraph (b)(1)(ii) would require on-site measurement of 
precipitation amounts at specified locations within the permit area, 
using self-recording devices. Measurement of precipitation amounts at 
the minesite is an important component of the surface water runoff 
control plan required under proposed 30 CFR 780.29. We propose to 
require that precipitation measurements continue through Phase II bond 
release under proposed 30 CFR 800.42(c) or for any longer period 
specified by the regulatory authority. Phase II bond release is the 
point at which revegetation has been established.
    Proposed paragraph (b)(1)(iv) would require that, at a minimum, 
each surface-water monitoring plan include monitoring of point-source 
discharges from the proposed operation as well as monitoring points 
located upgradient and downgradient of the proposed permit area in each 
perennial and intermittent stream within the proposed permit and 
adjacent areas to facilitate identification of potential mining-related 
changes in surface-water quantity or quality and to assist in an 
evaluation of whether any downgradient changes are the result of the 
mining and reclamation activities. This provision would be consistent 
with section 517(b)(2)(A) of SMCRA, which requires

[[Page 44506]]

that the regulatory authority specify ``monitoring sites to record the 
quantity and quality of surface drainage above and below the minesite 
as well as in the potential zone of influence.'' Point-source 
discharges would be located within the potential zone of influence.
    Proposed paragraph (b)(1)(v) would require that the plan describe 
how the monitoring data will be used to determine the impacts of the 
operation upon the hydrologic balance and the biological condition of 
perennial and intermittent streams within the permit and adjacent 
areas, as well as to prevent material damage to the hydrologic balance 
outside the permit area.
    Proposed paragraph (b)(1)(vi) would require that the plan describe 
how surface-water monitoring practices will comply with the sampling, 
analysis, and reporting requirements of proposed 30 CFR 777.13(a) and 
(b) to ensure that samples are collected and analyzed in a legally and 
scientifically valid manner. Proposed paragraph (b)(1)(vi) is 
consistent with the requirement in the text after section 517(b)(2)(D) 
of SMCRA that the regulatory authority set forth standards and 
procedures for monitoring data collection and analysis to assure the 
reliability and validity of the data.
    Proposed paragraph (b)(2)(i) would require that the surface-water 
monitoring plan provide for the monitoring of parameters that could be 
affected by the proposed operation if those parameters relate to 
applicable effluent limitation guidelines under 40 CFR part 434, the 
findings and predictions in the PHC determination prepared under 30 CFR 
780.20, the surface-water runoff control plan prepared under proposed 
30 CFR 780.29, the biological condition of perennial and intermittent 
streams and other surface-water bodies within the proposed permit and 
adjacent areas, the suitability of the surface water for existing and 
reasonably foreseeable uses as well as designated uses under section 
101(a) or 303(c) of the Clean Water Act, and the suitability of the 
surface water to support the premining and postmining land uses. 
Monitoring of these parameters would assist the permittee and 
regulatory authority in preventing material damage to the hydrologic 
balance outside the permit area and in determining compliance with the 
water supply protection and postmining land use requirements of SMCRA 
and its implementing regulations.
    Proposed paragraph (b)(2)(ii) would require quarterly monitoring of 
15 specific parameters, including, among others, selenium and the 
minimum water-quality parameters required by existing 30 CFR 
780.21(j)(2)(i) (pH, total iron, total manganese, total suspended 
solids, and total dissolved solids or specific conductance). As 
summarized in Part II of this preamble, selenium can have deleterious 
effects upon fish and human health. In addition, this proposed 
paragraph would require quarterly monitoring of major anions 
(including, at a minimum, bicarbonate, chloride, and sulfate), major 
cations (including, at a minimum, calcium, magnesium, potassium, and 
sodium), and the cation-anion balance. As summarized in Part II of this 
preamble, these anions and cations form salts that can alter water 
chemistry in a manner that sometimes has a significant adverse impact 
on aquatic life. With respect to water quantity, proposed paragraphs 
(b)(2)(ii)(A) and (iii)(B), like existing 30 CFR 780.21(j)(2)(i), would 
require quarterly measurement of flow rates. We propose to require use 
of generally-accepted professional flow measurement techniques, rather 
than subjective visual observations that involve no actual measurements 
and that will vary from observer to observer. Finally, proposed 
paragraph (b)(2)(ii) would require quarterly monitoring of certain 
metals (if present in discharges from prior underground mines) and any 
other parameters of local significance, as determined by the regulatory 
authority based upon the information collected and the analyses 
conducted under proposed 30 CFR 780.19 through 780.21.
    Proposed paragraph (b)(2)(iii) would not require that point-source 
discharges be monitored for the parameters listed in proposed paragraph 
(b)(2)(ii). Instead, as in existing 30 CFR 780.21(j)(2)(ii), the 
proposed rule would defer to the National Pollutant Discharge 
Elimination System permitting authority's determinations of which 
parameters must be monitored. We invite comment on whether, in the 
final rule, we should require monitoring of some or all of the 
parameters listed in proposed paragraph (b)(2)(ii) in point-source 
discharges to establish a more definitive connection between discharges 
from the minesite and trends observed at downgradient monitoring 
locations.
    To promote coordination of permitting and monitoring requirements 
under SMCRA and the Clean Water Act, proposed paragraph (b)(2)(iv) 
would require that the surface-water monitoring plan be revised to 
include any site-specific monitoring requirements imposed by the 
National Pollutant Discharge Elimination System permitting authority or 
the agency responsible for administration of section 404 of the Clean 
Water Act.\367\ This provision recognizes that this information may not 
be available at the time of application for the SMCRA permit and, thus, 
may need to be added later via a permit revision.

---------------------------------------------------------------------------

    Proposed paragraph (b)(3) would require that the regulatory 
authority reconsider the adequacy of the surface-water monitoring plan 
at two points during the permit application review process. The first 
reconsideration would occur after the regulatory authority completes 
the technical review of the application. At that point, the regulatory 
authority may require that the permit applicant revise the plan to 
increase the frequency of monitoring, to require monitoring of 
additional parameters, or to require monitoring at additional 
locations, if the additional requirements would contribute to 
protection of the hydrologic balance. The second reconsideration would 
occur after preparation of the CHIA under proposed 30 CFR 780.21. At 
that point, the regulatory authority would be responsible for ensuring 
that the surface-water monitoring plan requires monitoring of all 
parameters for which the CHIA establishes material damage criteria; 
i.e., all parameters of concern. These reconsiderations are intended to 
ensure that the monitoring plans are designed to provide sufficiently 
comprehensive monitoring data to enable both the permittee and the 
regulatory authority to identify any adverse impacts on surface water 
in time to take corrective action to prevent material damage to the 
hydrologic balance outside the permit area.
Proposed Paragraph (c): Biological Condition Monitoring Plan
    Proposed paragraph (c)(1) would require that each permit 
application include a plan for monitoring the biological condition of 
perennial and intermittent streams within the proposed permit area and 
the adjacent area. The proposed rule would require that the plan be 
adequate to evaluate the impacts of the mining operation on the 
biological condition of those streams and to determine in a timely 
manner whether corrective action is needed to prevent the operation 
from causing material damage to the hydrologic balance outside the 
permit area.
    Proposed paragraph (c)(2)(i) would specify that the plan must 
require use of a multimetric bioassessment protocol that meets the 
requirements of proposed 30 CFR 780.19(e)(2). In essence, this 
provision requires use of a multimetric

[[Page 44507]]

bioassessment protocol approved by the state or tribal agency 
responsible for preparing the water quality inventory report required 
under section 305(b) of the Clean Water Act \368\ or other 
scientifically-valid, multimetric bioassessment protocols used by 
agencies responsible for implementing the Clean Water Act. The 
bioassessment protocol must be based upon the presence or absence, 
population levels, and biomass of an appropriate array of aquatic 
organisms, including benthic macroinvertebrates. It must require 
identification of macroinvertebrates to the genus level because a 
bioassessment protocol that requires identification of aquatic 
organisms only to the family level may not be capable of 
differentiating between pollution-tolerant and pollution-intolerant 
genera within the same family, while a bioassessment protocol that 
identifies organisms to the species level may not be consistent with 
available indices of biological integrity. Finally, the protocol must 
result in the calculation of index values for both habitat and 
macroinvertebrates and provide a correlation of index values to the 
capability of the stream to support designated uses under section 
101(a) or 303(c) of the Clean Water Act.
---------------------------------------------------------------------------

    \368\ 33 U.S.C. 1315(b).
---------------------------------------------------------------------------

    Proposed paragraph (c)(2)(ii) would require that the plan identify 
biological condition monitoring locations in each perennial and 
intermittent stream within the proposed permit and adjacent areas. 
Proposed paragraph (c)(2)(iii) would require that the plan establish a 
sampling frequency that must be no less than annual, but not so 
frequent as to unnecessarily deplete the populations of the species 
being monitored. Proposed paragraph (c)(2)(iv) would provide that the 
plan must require submission of biological condition monitoring data to 
the regulatory authority on an annual basis.
    Proposed paragraph (c)(3) would require that the regulatory 
authority reconsider the adequacy of the biological condition 
monitoring plan after completing preparation of the CHIA under proposed 
30 CFR 780.21. The proposed rule would require that, if necessary, the 
regulatory authority issue an order to the applicant to revise the plan 
to correct any deficiencies.
    The monitoring requirements in proposed paragraph (c) would assist 
in more completely implementing section 515(b)(24) of SMCRA,\369\ which 
requires that surface coal mining and reclamation operations be 
conducted so as to minimize disturbances to and adverse impacts on 
fish, wildlife, and related environmental values to the extent possible 
using the best technology currently available. Proposed paragraph (c) 
also would provide a means of implementing the definition of ``material 
damage to the hydrologic balance outside the permit area'' that we 
propose to adopt in 30 CFR 701.5, which relies in part upon designated 
uses of surface water under section 101(a) or section 303(c) of the 
Clean Water Act. The biological condition of perennial and intermittent 
streams and other surface waters determines whether those waters are 
capable of attaining their designated uses.
---------------------------------------------------------------------------

    \369\ 30 U.S.C. 1265(b)(24).
---------------------------------------------------------------------------

Proposed Paragraph (d): Exceptions
    Proposed paragraph (d)(1) would allow potential permit applicants 
to request that the regulatory authority modify the groundwater and 
surface-water monitoring plan requirements of proposed paragraphs (b) 
and (c) and modify or waive the biological condition monitoring plan 
requirements of proposed paragraph (c) if the proposed permit area 
includes only lands eligible for remining. The proposed rule would 
allow the regulatory authority to approve the request if it determines 
that an alternative monitoring plan will be adequate to monitor the 
impacts of the proposed operation on groundwater and surface water, 
based upon an evaluation of the quality of groundwater and surface 
water and the biological condition of the receiving stream at the time 
of application. The exception for remining operations would provide an 
incentive to mine and reclaim previously mined areas without the use of 
public funds. Streams in the vicinity of previously mined areas also 
are likely to be of lower quality than streams in unmined watersheds 
because of the adverse impacts of previous mining.
    Proposed paragraph (d)(2) would allow permit applicants to request 
that the regulatory authority waive the biological condition monitoring 
plan requirements of proposed paragraph (c) if the applicant 
demonstrates, and the regulatory authority finds in writing, that the 
proposed operation will not mine through or bury a perennial or 
intermittent stream; create a point-source discharge to any perennial, 
intermittent, or ephemeral stream; or modify the baseflow of any 
perennial or intermittent stream. If the applicant meets all 
requirements except the one concerning a point-source discharge, the 
proposed rule would allow the regulatory authority to approve limiting 
the biological condition monitoring plan requirements to only the 
stream that will receive the point-source discharge.
Proposed Paragraph (e): Coordination With Clean Water Act Agencies
    Proposed paragraph (e) would require that SMCRA regulatory 
authorities consult with the agencies responsible for issuing permits, 
authorizations, and certifications under the Clean Water Act and make 
best efforts to minimize differences in monitoring locations and 
reporting requirements and to share data to the extent practicable and 
consistent with each agency's mission, statutory requirements, and 
implementing regulations. Coordination could reduce both costs and the 
overall regulatory impact to the industry, as well as improving 
regulatory efficiency. In addition, the proposed requirement would be 
consistent with the intent of the regulatory coordination provisions of 
section 713 of SMCRA.\370\

12. Section 780.24: What requirements apply to the postmining land use?
    Proposed 30 CFR 780.24 would consolidate the requirements for 
approval of postmining land uses that appear in existing 30 CFR 
780.23(b), 816.133(b), and 816.133(c). We also propose to add a surface 
mining counterpart to the interpretive rules concerning postmining land 
use changes in existing 30 CFR 784.200(a) and 817.200(d)(1). In 
addition, we propose to revise existing 30 CFR 780.24 to improve 
consistency with SMCRA and its legislative history and to more 
completely implement the environmental protection purposes of SMCRA, 
including the fish and wildlife protection and enhancement requirements 
of section 515(b)(24) of SMCRA,\371\ while remaining mindful of the 
requirement in section 508(a)(3) of SMCRA \372\ to consider the 
comments of the surface owner and state and local governments and 
agencies. Our proposed revisions to the existing requirements also are 
consistent with section 515(b)(23) of SMCRA,\373\ which provides that 
surface coal mining and reclamation operations must ``meet such other 
criteria as are necessary to achieve reclamation in accordance with the 
purposes of this Act, taking into consideration the physical, 
climatological, and other characteristics of the site.''

[[Page 44508]]

Proposed Paragraph (a): What postmining land use information must my 
application contain?
    Section 515(b)(2) of SMCRA \374\ requires that surface coal mining 
and reclamation operations ``restore the land affected to a condition 
capable of supporting the uses which it was capable of supporting prior 
to any mining, or higher or better uses of which there is a reasonable 
likelihood.'' Section 508(a)(3) of SMCRA \375\ requires that each 
reclamation plan include a statement of ``the use which is proposed to 
be made of the land following reclamation, including a discussion of 
the utility and capacity of the reclaimed land to support a variety of 
alternative uses.'' Combining these two statutory provisions, proposed 
paragraph (a)(1) would require that each permit application include 
both a description and a map of the proposed postmining land use or 
uses and a discussion of the utility and capability of the reclaimed 
land to support a variety of other uses, including the uses that the 
land was capable of supporting before any mining, as identified in the 
narrative analysis required under 30 CFR 779.22.
---------------------------------------------------------------------------

    \374\ 30 U.S.C. 1265(b)(2).
    \375\ 30 U.S.C. 1258(a)(3).
---------------------------------------------------------------------------

    Proposed paragraph (a)(2) would require that the land use or uses 
be described in terms of the categories listed in our definition of 
``land use'' in 30 CFR 701.5, which would assist the regulatory 
authority in determining compliance with provisions of our regulations 
that are tied to land use; e.g., alternative postmining land uses, 
revegetation standards, and exceptions from approximate original 
contour restoration requirements, and provide a baseline for 
application of these provisions on a national basis.
    Proposed paragraph (a)(3) would require that the application 
explain how the proposed postmining land use is consistent with 
existing state and local land use policies and plans. Addition of this 
requirement would be consistent with section 508(a)(3) of SMCRA,\376\ 
which requires that the reclamation plan include an explanation of the 
relationship of the proposed postmining land use to existing land use 
policies and plans. That section of SMCRA also requires that the 
application include comments from state and local governments or 
agencies that would have to approve or authorize the proposed land use. 
Furthermore, section 515(b)(2) of SMCRA \377\ prohibits the approval of 
alternative postmining land uses that are ``inconsistent with 
applicable land use policies and plans.'' Therefore, it would be 
reasonable to conclude that Congress intended for all postmining land 
uses to be consistent with state and local land use policies and plans, 
especially since regulation of land use has traditionally been the 
province of state and local governments.
---------------------------------------------------------------------------

    \376\ 30 U.S.C. 1258(a)(3).
    \377\ 30 U.S.C. 1265(b)(2).
---------------------------------------------------------------------------

    Proposed paragraph (a)(4) is substantively identical to the 
corresponding existing rule at 30 CFR 780.23(c). Proposed paragraph 
(a)(5) is substantively identical to the corresponding existing rule at 
30 CFR 780.23(b)(1) with the exception that the proposed rule clarifies 
that the permit applicant must identify any support facilities (not 
just activities as in the existing rule) needed to achieve the 
postmining land use. (Support facilities are equipment repair areas, 
mine offices, parking lots, and other surface areas upon which are 
sited structures, facilities, or other property or material resulting 
from or incident to the activities listed in paragraph (a) of the 
definition of ``surface coal mining operations'' in 30 CFR 700.5.) The 
regulatory authority needs this information when evaluating whether the 
proposed postmining land use can be achieved and in deciding whether to 
allow mining-related structures to be retained as part of the 
postmining land use.
    Proposed paragraph (a)(6)(i) would specify that the application 
must provide the demonstration required under proposed paragraph (b)(1) 
if the applicant proposes to restore the proposed permit area or a 
portion thereof to a condition capable of supporting a higher or better 
use or uses rather than to a condition capable of supporting the use or 
uses that the land supported before any mining. This provision is 
substantively identical to existing 30 CFR 780.23(b)(2) except as 
discussed in the preamble to proposed paragraph (b) below.
    Proposed paragraph (a)(6)(ii) would require that an applicant 
requesting approval of a higher or better alternative postmining land 
use disclose any monetary compensation, item of value, or other 
consideration offered to the landowner by the applicant or the 
applicant's agent in exchange for the landowner's agreement to a 
postmining land use that differs from the premining use. Adoption of 
this provision is supported by section 515(b)(2) of SMCRA, which 
requires that surface coal mining and reclamation operations--

restore the land affected to a condition capable of supporting the 
uses which it was capable of supporting prior to any mining, or 
higher or better uses of which there is reasonable likelihood, so 
long as such use or uses do not present any actual or probably 
hazard to public health or safety or pose any actual or probable 
threat of water diminution or pollution, and the permit applicants' 
declared proposed land use following reclamation is not deemed to be 
impractical or unreasonable, inconsistent with applicable land use 
policies and plans, involves unreasonable delay in implementation, 
or is violative of Federal, State, or local law.

    Disclosure of whether a landowner has been provided with or is 
reasonably expected to be provided with compensation or other 
consideration for any postmining land use changes would allow the 
regulatory authority to better understand whether the proposed 
postmining land use change is one that the landowner genuinely desires 
on its own merits and is reasonably likely to be achieved, or whether 
the landowner agreed to the land use change for short-term financial 
gain or other reasons. This type of short-term land use decision-making 
is contrary to the broader purposes identified in SMCRA, such as 
``protect[ing] society and the environment from the adverse effects of 
surface mining coal operations'' in section 102(a) and assuring that 
``operations are conducted as to protect the environment'' in section 
102(d).
Proposed Paragraph (b): What requirements apply to the approval of 
alternative postmining land uses?
    Existing 30 CFR 780.23(b)(2) provides that the application must 
include all materials needed for approval of an alternative postmining 
land use under 30 CFR 816.133 if the proposed postmining land use 
differs from the premining use. Existing 30 CFR 816.133(b) further 
provides that the ``premining uses of land to which the postmining land 
use is compared shall be those uses which the land previously 
supported, if the land has not been previously mined and has been 
properly managed.'' In new section 780.24, we propose to require 
compliance with the alternative postmining land use approval 
requirements only when the applicant or permittee proposes to restore 
the land to a condition capable of supporting higher or better uses (a 
term that we define in 30 CFR 701.5) rather than to a condition capable 
of supporting the uses that it could support before any mining. The 
proposed language better tracks the underlying statutory provision in 
section 515(b)(2) of SMCRA,\378\ as quoted above. In addition, it is 
consistent with the legislative history of section 508(a) of SMCRA:

    The description [of premining land use capability] is to serve 
as a benchmark against which the adequacy of reclamation and the 
degradation resulting from the proposed mining may be measured. It 
is important that the potential utility which the land had for a 
variety of uses be the benchmark rather than any single, possibly 
low value, use which by circumstances may have existed at the time 
mining began.\380\

    By requiring approval only when the change is to a higher or better 
use, our proposed rule also would avoid unnecessary paperwork on the 
part of permit applicants and conserve often-scarce regulatory 
authority resources.
    We propose to delete the provision in existing 30 CFR 816.133(b) 
requiring that the land be properly managed before the premining land 
use may be compared with the proposed alternative postmining land use. 
There is no statutory counterpart to this provision of the existing 
rule, nor is it supported by the legislative history of SMCRA. 
Furthermore, the criteria for approval of proposed alternative 
postmining land uses in existing 30 CFR 816.133(c) bear no relationship 
to whether the land was properly managed before mining. In addition, 
proper management is a subjective determination. To the extent that 
this provision could be construed as requiring that the regulatory 
authority reject a proposed higher or better postmining land use that 
involves less intensive management than the premining use, the existing 
rule is inconsistent with the preamble to our definition of ``land 
use'' in 30 CFR 701.5, which states that the land use categories in the 
definition are not hierarchical.\381\ Consistent with that statement, 
the same rulemaking defined ``higher or better uses'' as meaning 
``postmining land uses that have a higher economic value or nonmonetary 
benefit to the landowner or the community than the premining land 
uses.'' We are not proposing any changes to that definition. Therefore, 
the provision in existing 30 CFR 816.133(b) requiring that the land be 
properly managed before the premining land use may be compared with the 
proposed alternative postmining land use has no statutory basis and, in 
any case, is not feasible.

    Proposed paragraph (b) combines existing 30 CFR 780.23(b)(2), which 
requires that the permit application include all materials needed for 
approval of an alternative postmining land use under 30 CFR 816.133, 
with the alternative postmining land use approval criteria of 30 CFR 
816.133(c). Proposed paragraph (b)(1) sets forth permit application 
requirements, while proposed paragraph (b)(2) contains requirements 
applicable to the regulatory authority's decision-making process. In 
essence, proposed paragraph (b)(1), like existing 30 CFR 780.23(b)(2), 
requires that the permit applicant submit a demonstration that the 
request for an alternative postmining land use meets the criteria for 
approval, while proposed paragraph (b)(2), like existing 30 CFR 
816.133(c), specifies when the regulatory authority may approve a 
request for an alternative postmining land use.
    Proposed paragraph (b)(1) would retain the criteria in the 
corresponding existing rules at 30 CFR 816.133(c) for approving 
alternative postmining land uses, while requiring that the permit 
applicant demonstrate compliance with both those criteria and several 
new criteria intended to promote environmental protection and 
restoration of fish and wildlife habitat consistent with section 
515(b)(24) of SMCRA \382\ and the purposes in paragraphs (a), (d), and 
(f) of section 102 of SMCRA.\383\ Addition of the new criteria also 
would be consistent with section 515(b)(23) of SMCRA,\384\ which 
requires that surface coal mining and reclamation operations ``meet 
such other criteria as are necessary to achieve reclamation in 
accordance with the purposes of this Act, taking into consideration the 
physical, climatological, and other characteristics of the site.''

    As previously stated, proposed paragraph (b)(1)(i) would retain the 
provision in the corresponding existing rules at 30 CFR 816.133(c)(1) 
that there must be a reasonable likelihood of achievement of the 
proposed higher or better alternative postmining land use. However, we 
propose to expand upon this requirement by adding language that would 
require the applicant to document that a reasonable likelihood of 
achieving the higher or better use exists through submission of, for 
example, real estate and construction contracts, plans for installation 
of any necessary infrastructure, procurement of any necessary zoning 
approvals, landowner commitments, economic forecasts, and studies by 
land use planning agencies, as applicable. The additional language 
would flesh out the requirement in section 515(b)(2) of SMCRA \385\ 
that there be a reasonable likelihood of achievement of the proposed 
land use. In the past, approved alternative postmining land uses have 
not been implemented on some reclaimed minesites, including some sites 
for which the regulatory authority approved a variance from approximate 
original contour restoration requirements for the purpose of achieving 
a particular alternative postmining land use. Our proposed rule changes 
concerning the reasonable likelihood of achievement of the alternative 
postmining land use are intended to prevent recurrences of situations 
in which the regulatory authority approves an alternative postmining 
land use that has little chance of being implemented in the reasonably 
foreseeable future. The proposed rule changes thus would improve 
compliance with the conditions for approval of higher or better uses 
under section 515(b)(2) of SMCRA \386\ and the approximate original 
contour restoration requirements of section 515(b)(3) of SMCRA.\387\

designed to prevent material damage to the hydrologic balance outside

    Proposed paragraph (b)(2) would allow the regulatory authority to 
approve a request for an alternative postmining land use if it first 
consults with the landowner or the land management agency having 
jurisdiction over the lands to which the use would apply and finds in 
writing that the applicant has made the demonstration required under 
proposed paragraph (b)(1). These proposed provisions are substantively 
identical to the corresponding existing rules at 30 CFR 816.133(c), 
with the exception of the proposed requirement that the finding be in 
writing and the addition of the new and modified criteria in paragraph 
(b)(1) as discussed above.
Proposed Paragraph (c): What requirements apply to permit revision 
applications that propose to change the postmining land use?
    Proposed paragraph (c) would provide that, consistent with the 
decision in PSMRL I, Round II,\392\ permittees may use the permit 
revision process to change the postmining land use after permit 
issuance. The proposed rule would specify that the application for a 
permit revision must be processed as a significant revision if the 
permittee proposes to restore the land to a condition capable of 
supporting higher or better uses rather than to a condition capable of 
supporting the uses that it was capable of supporting before any 
mining.

---------------------------------------------------------------------------

    Proposed paragraph (c) would provide a surface mining counterpart 
to the interpretive rules for underground mines at 30 CFR 784.200 and 
817.200(d)(1), which specify that the requirements for approval of an 
alternative postmining land use may be met via the permit revision 
process rather than as part of the original permit application. We do 
not now interpret our existing surface mining rules as prohibiting 
permittees from submitting permit revision applications to change the 
postmining land use after permit issuance, nor have we interpreted 
those rules as doing so in the past. Therefore, the only effect of 
proposed paragraph (c) would be to require that a proposed change to a 
higher or better postmining land use be processed as a significant 
revision. As provided in 30 CFR 774.13(a)(2), an application for a 
significant permit revision must comply with the public notice and 
public participation requirements that apply to an application for a 
new permit.
    Unlike existing 30 CFR 784.200 and 817.200(d)(1), which classify 
any change in postmining land use as a significant permit revision, we 
propose to apply this requirement only to a proposed change to a higher 
or better use. A change from one postmining land use that the land was 
capable of supporting prior to mining to another postmining land use 
that the land was capable of supporting prior to mining would no longer 
require approval as an alternative postmining land use, nor would a 
request for such a change need to be processed as a significant permit 
revision.
    Our proposed rule would improve consistency with section 515(b)(2) 
of SMCRA,\393\ which requires that surface coal mining and reclamation 
operations ``restore the land affected to a condition capable of 
supporting the uses which it was capable of supporting prior to any 
mining, or higher or better uses of which there is a reasonable 
likelihood.'' The statutory provision distinguishes only between uses 
that the land was capable of supporting before mining and higher or 
better uses; i.e., it establishes criteria for approval of higher or 
better uses, but no criteria for approval of any of the uses that the 
land was capable of supporting before mining.

    \393\ 30 U.S.C. 1265(b)(2).

Proposed Paragraph (d): What restrictions apply to the retention of 
mining-related structures?
    Proposed paragraph (d) would establish new requirements pertinent 
to the retention of mining-related structures in support of the 
postmining land use. First, the applicant or permittee would have to 
demonstrate, and the regulatory authority would have to find in 
writing, that the size and characteristics of mining-related structures 
(other than roads and impoundments) proposed for retention for 
potential use as part of the postmining land use are consistent with 
and proportional to the needs of the postmining land use. For example, 
retention of an entire coal preparation plant building as a storage 
facility for an agriculture or silvicultural postmining land use would 
be disproportionate to the needs for the postmining land use. Second, 
the amount of bond required for the permit must include the cost of 
removing the structure and reclaiming the land to a condition capable 
of supporting the premining uses. Third, the reclamation plan must 
specify that the permittee will remove any structure not in use as part 
of the approved postmining land use by the end of the revegetation 
responsibility period and reclaim the land upon which it was located.
    These measures are intended to ensure that only mining-related 
structures with a bona fide role in supporting the postmining land use 
are retained. These provisions should minimize the number of mining-
related structures that are retained, ostensibly to support the 
postmining land use, but that are abandoned after final bond release 
and become safety hazards, attractive nuisances, or a visual blight on 
the landscape. Thus, proposed paragraph (d) would more fully implement 
section 102(a) of SMCRA,\394\ which provides that one of the purposes 
of SMCRA is to protect society and the environment from the adverse 
effects of surface coal mining operations. In addition, section 
515(b)(2) of SMCRA \395\ allows the approval of higher or better 
postmining land uses only if they do not present any actual of probable 
hazard to public health or safety. Logically, the same requirement 
should apply to retention of mining-related structures that did not 
exist prior to mining.

Proposed Paragraph (e): What special provisions apply to previously 
mined areas?
    Proposed paragraph (e) would contain the postmining land use 
requirements for previously mined areas, as that term is defined in 30 
CFR 701.5. They do not differ substantively from the corresponding 
requirements in the last sentence of the existing rules at 30 CFR 
816.133(b) except for the proposed addition of a requirement that the 
revegetation plan require the use of native tree and shrub species for 
revegetation of all portions of the proposed permit area that were 
forested at the time of application or that would revert to forest 
under conditions of natural succession, provided that the planting of 
trees and shrubs on those lands would not be inconsistent with 
achievement of the proposed postmining land use. The added requirement 
would more fully implement section 515(b)(19) of SMCRA,\396\ which 
requires establishment of a diverse, effective, permanent vegetative 
cover of the same seasonal variety native to the area, and the fish and 
wildlife protection and

13. Section 780.25: What information must I provide for siltation 
structures, impoundments, and refuse piles?
Changes To Conform With the 1983 Revisions to Definitions and 
Performance Standards
    On September 26, 1983 (48 FR 44006), we revised the definitions and 
performance standards in our regulations relating to coal mine waste to 
be more consistent with the terminology used by the Mine Safety and 
Health Administration (MSHA). As we stated at 48 FR 44009, ``[i]t is 
undesirable to have two regulatory programs for the same subject that 
contain conflicting standards or which use fundamentally different 
terminology.''
    Among other things, we adopted definitions of three new terms in 30 
CFR 701.5. Coal mine waste is defined as ``coal processing waste and 
underground development waste.'' Impounding structure is defined as ``a 
dam, embankment, or other structure used to impound water, slurry, or 
other liquid or semi-liquid material.'' Refuse pile is defined as ``a 
surface deposit of coal mine waste that does not impound water, slurry, 
or other liquid or semi-liquid material.'' The latter two terms are 
consistent with the terminology of MSHA's regulations. ``Refuse pile'' 
replaces the term ``coal processing waste bank'' that we used in our 
previous regulations, while the term ``impounding structure'' includes, 
but is not limited to, all structures that our rules previously 
referred to as coal processing waste dams or embankments.
    In concert with the new definition of coal mine waste, we revised 
our performance standards at 30 CFR 817.71 through 817.74 to eliminate 
the language that combined underground development waste with excess 
spoil for purposes of performances standards for underground mines. 
Because the definition of coal mine waste includes underground 
development waste, we revised our regulations to specify that the 
disposal of underground development waste is subject to the performance 
standards for refuse piles at 30 CFR 817.83 rather than the performance 
standards for the disposal of excess spoil that applied under the old 
rules.
    However, we did not revise our permitting requirements in a similar 
fashion at that time. Therefore, we now propose to modify 30 CFR parts 
780 and 784 to harmonize the terminology in those rules with our 1983 
changes to the definitions and performance standards concerning coal 
mine waste. In essence, we propose to (1) replace the term ``coal 
processing waste banks'' with ``refuse piles'' and (2) replace the term 
``coal processing waste dams and embankments'' with references to coal 
mine waste impounding structures.
Proposed Paragraph (a): General Requirements
    In addition to the changes in terminology, we propose to revise 
existing paragraph (a)(1)(iii) to require that the general plan for 
each proposed siltation structure, impoundment, or refuse pile include 
the hydrologic and geologic information needed to assess the hydrologic 
impact of the structure. The existing rule requires submission of only 
``preliminary'' hydrologic and geologic information. We propose to 
remove the word ``preliminary'' because preliminary information 
typically would not be sufficient to assess the hydrologic impact of a 
proposed structure.
    We propose to revise existing paragraph (a)(1)(iv) to require that 
the general plan for each proposed siltation structure, impoundment, or 
refuse pile contain a report describing the results of a geotechnical 
investigation of the potential effect on the structure if subsurface 
strata should subside as a result of past, current, or future 
underground mining operations beneath or within the proposed permit and 
adjacent areas. Geotechnical investigations may include site 
reconnaissance, drilling, or some combination of these with geophysical 
investigations (ground-penetrating radar, seismic investigations, 
etc.). The existing rule requires only a survey describing the 
potential effect of subsidence resulting from past underground mining 
operations. A survey alone would provide insufficient information to 
evaluate the potential effects of subsidence.
    Therefore, to promote long-term structural stability, we propose to 
require a geotechnical investigation instead of a survey and we propose 
to require consideration of the potential effects of subsidence from 
past, existing, and future underground mining operations, beneath or 
within the proposed permit and adjacent areas, not just the potential 
effects of past underground mining operations within an unspecified 
area. The design needs to ensure that the structure will be capable of 
withstanding all potential impacts of any subsidence that may occur 
during the life of the proposed structure. We propose to add the 
reference to the proposed permit and adjacent areas to ensure that the 
investigation includes all underground mining operations that have the 
potential to cause subsidence that may affect the proposed structure, 
not just operations within the proposed permit area.
    Finally, we propose to specify that the investigation report must 
identify design and construction measures that would prevent adverse 
subsidence-related impacts on the structure whenever impacts of that 
nature are a possibility. In short, proposed paragraph (a)(1)(iv) is 
intended to protect against failure of the impoundment embankment or 
other impoundment failures as a result of subsidence. Impoundment 
stability, especially for large impoundments, is important to protect 
the public, private and public property, and the environment from the 
adverse effects of flooding and other consequences of impoundment 
failure, consistent with the purposes of SMCRA in paragraphs (a) and 
(d) of section 102 of the Act.\398\

    \398\ 30 U.S.C. 1202(a) and (d).
---------------------------------------------------------------------------

    We propose to redesignate existing paragraph (a)(1)(v) as paragraph 
(a)(1)(vi) and add a new paragraph (a)(1)(v) to require that the 
general plan for each impoundment include an analysis of the potential 
for the impoundment to drain into subjacent underground mine workings, 
together with an analysis of the impacts of such drainage. The Martin 
County Slurry Spill incident in Martin County, Kentucky on October 11, 
2000, illustrates the magnitude of environmental damage that can result 
when impounded coal refuse slurry breaks through into adjacent 
underground mine workings that open to the surface. In this case, the 
mine openings discharged 306 million gallons of slurry into two 
tributaries of the Tug Fork River (Coldwater Fork and Wolf Creek). The 
slurry covered nearby residents' yards to a depth of as much as 5 feet, 
visibly polluted more than 100 miles of waterways, including the Big 
Sandy and Ohio Rivers, and devastated aquatic life in 70 miles of 
stream. Six public water intakes were adversely affected and 
alternative water supplies had to be arranged for 27,000 residents. 
Cleanup costs were approximately $59 million.\399\

    Proposed paragraph (a)(1)(v) is intended to ensure that all types 
of

[[Page 44512]]

impoundments constructed for coal mining purposes are designed to 
prevent similar breakthroughs. This design requirement would reduce the 
probability of breakthroughs into underground mine workings, thus 
benefiting the public, the environment, and mine operators by avoiding 
the environmental and property damage and cleanup expenses that may 
result from those breakthroughs, consistent with the purposes of SMCRA 
in paragraphs (a) and (d) of section 102 of the Act.\400\

    Paragraph (a)(2) sets forth design requirements for all 
impoundments other than low-hazard impoundments. We propose to revise 
the introductory text of existing paragraph (a)(2) for clarity and 
redesignate that text as paragraph (a)(2)(i). Proposed paragraph 
(a)(2)(i) would specify that the detailed design plan requirements of 
proposed paragraph (a)2)(ii) would apply to all structures meeting the 
MSHA criteria of 30 CFR 77.216(a), as well as to all structures that 
meet the Significant Hazard Class or High Hazard Class criteria for 
dams in NRCS publication Technical Release No. 60, ``Earth Dams and 
Reservoirs,'' regardless of whether those structures meet the MSHA 
criteria of 30 CFR 77.216(a).
    We propose to revise redesignated paragraph (a)(2)(i) to update the 
incorporation by reference of the NRCS publication ``Earth Dams and 
Reservoirs,'' Technical Release No. 60 (210-VI-TR60, October 1985), by 
replacing the reference to the October 1985 edition with a reference to 
the superseding July 2005 edition. Consistent with the terminology in 
the newer edition, we propose to replace references to Class B or C dam 
criteria with references to Significant Hazard Class or High Hazard 
Class dam criteria, respectively. Only the terminology has changed--the 
actual criteria remain the same as before. The newer publication is not 
available from the National Technical Information Service, but is 
available online from the NRCS (the successor to the Soil Conservation 
Service). Consequently, we propose to delete the ordering information 
pertinent to the National Technical Information Service and replace it 
with the Internet address at which the publication may be reviewed and 
from which it may be downloaded without charge. We also propose to 
update the address and location of our administrative record room and 
the Internet address information for the National Archives and Records 
Administration.
    In addition, we propose to redesignate existing paragraphs 
(a)(2)(i) through (iv) as paragraphs (a)(2)(ii)(A) through (D) and add 
introductory text to proposed paragraph (a)(2)(ii). The introductory 
text is a revised version of the last sentence of the introductory text 
of existing paragraph (a)(2), modified to be consistent with proposed 
paragraph (a)(2)(i). As it currently exists, redesignated paragraph 
(a)(2)(ii)(B) requires that the detailed design plan include any 
geotechnical investigation, design, and construction requirements. This 
language is ambiguous because it does not identify the geotechnical 
investigation, design, and construction requirements to which it 
refers. Therefore, we propose to revise redesignated paragraph 
(a)(2)(ii)(B) to require that the detailed design plan for any 
structure that meets the applicability provisions of proposed paragraph 
(a)(2)(i) incorporate any design and construction measures identified 
in the geotechnical investigation report prepared under 30 CFR 
780.25(a)(1)(iv) as necessary to protect against potential adverse 
impacts from subsidence resulting from underground mine workings 
underlying or adjacent to the structure. These measures might include 
grouting or backstowing of mine voids or surface mining of seams within 
the impoundment safety zone. In short, proposed paragraph (a)(2)(ii)(B) 
would operate in conjunction with proposed paragraph (a)(1)(iv) to 
protect against failure of the impoundment embankment or other 
impoundment failures as a result of subsidence. Impoundment stability, 
especially for large impoundments, is important to protect the public, 
private and public property, and the environment from the adverse 
effects of flooding and other consequences of impoundment failure, 
consistent with the purposes of SMCRA in paragraphs (a) and (d) of 
section 102 of the Act.\401\

    \401\ 30 U.S.C. 1202(a) and (d).
---------------------------------------------------------------------------

    We propose to reinstate former paragraph (a)(3), which was 
erroneously removed as part of the codification process for a rule 
published December 12, 2008 (73 FR 75814). This paragraph contains 
detailed design plan requirements for structures not covered under 
paragraph (a)(2).
Proposed Paragraph (c): Permanent and Temporary Impoundments
    Both the existing and proposed versions of paragraph (c) contain 
design requirements that apply to all impoundments. To improve clarity 
and consistency with other regulations, we propose to revise existing 
paragraph (c)(2) by replacing the term ``Mine Safety and Health 
Administration'' with a citation to 30 CFR 77.216(a), which contains 
the MSHA impoundment criteria to which paragraph (c)(2) refers. As 
revised, proposed paragraph (c)(2) would require that plans for 
impoundments meeting MSHA criteria comply with MSHA's impoundment 
design requirements at 30 CFR 77.216-2. We propose to delete the 
requirement that those plans also comply with 30 CFR 77.216-1. The 
requirement that we propose to delete is not germane to permit 
applications and plans because it contains signage requirements that 
apply only to impoundments that already exist or are under 
construction. In the second sentence, we propose to delete an obsolete 
cross-reference to paragraph (a).
    We also propose to revise paragraph (c)(2) to clarify that the 
requirement that the permit application include the plan submitted to 
MSHA applies only to those portions of the plan that are complete at 
the time of submission of the SMCRA permit application. Impoundment 
plans normally are submitted to MSHA in stages; they may not be 
complete or even started at the time that the applicant submits an 
application for the SMCRA permit. SMCRA-related permit application 
information requirements are sufficiently comprehensive that the 
regulatory authority does not need the MSHA plan to process the SMCRA 
permit application or to ensure the stability of proposed structures.
    We propose to redesignate existing paragraph (f) as paragraph 
(c)(4). That paragraph applies only to impoundments that meet certain 
criteria in Technical Release No. 60 or the MSHA criteria of 30 CFR 
77.216(a). It has no relevance to the other structures to which 30 CFR 
780.25 applies (low-hazard impoundments and refuse piles). Therefore, 
it is more appropriate to include the stability analysis requirements 
of existing paragraph (f) as part of proposed paragraph (c), which 
applies only to impoundments, including coal mine waste impoundments. 
We also propose to revise this paragraph to be consistent with the 
terminology in the July 2005 edition of Technical Release No. 60 by 
replacing references to Class B or C dam criteria with references to 
Significant Hazard Class or High Hazard Class dam criteria, 
respectively. Only the terminology would change; the actual criteria 
would remain the same as before. Finally, we propose to revise this 
paragraph to clarify that the stability analyses that it requires must 
address

[[Page 44513]]

static, seismic, and post-earthquake (liquefaction) conditions because 
those conditions are all part of a comprehensive stability analysis.
Proposed Paragraph (d): Coal Mine Waste Impoundments and Refuse Piles
    As discussed in the introductory portion of the preamble to this 
section, we propose to modify 30 CFR parts 780 and 784 to harmonize the 
terminology in those rules with our 1983 changes to the definitions and 
performance standards concerning coal mine waste. In essence, ``refuse 
pile'' would replace the term ``coal processing waste bank'' as used in 
existing parts 780 and 784, while the term ``impounding structure'' 
would include all structures that existing parts 780 and 784 refer to 
as coal processing waste dams or embankments. We also use the term 
``coal mine waste impoundment'' to refer to the impounding structure in 
combination with the basin behind the impounding structure. We propose 
to combine existing paragraph (d), which contains design requirements 
for coal processing waste banks, and existing paragraph (e), which 
contains design requirements for coal processing waste dams and 
embankments, into a revised paragraph (d) that uses the newer 
terminology. Proposed paragraph (d) would apply to any application that 
proposes to place coal mine waste in a refuse pile or impoundment or 
use coal mine waste to construct an impounding structure. We are adding 
the language concerning use of coal mine waste to construct an 
impounding structure because proposed paragraph (d) is the permitting 
counterpart of the performance standards for coal mine waste disposal 
in 30 CFR 816.81 through 816.84. Section 816.84 applies to both 
impounding structures constructed of coal mine waste and impounding 
structures intended to impound coal mine waste. Our proposed revision 
would expand the scope of proposed paragraph (d) to coincide with the 
scope of the corresponding performance standards.
    Proposed paragraph (d)(1) corresponds to existing paragraph (d), 
which requires that coal processing waste banks be designed to comply 
with the requirements of 30 CFR 816.81 through 816.84. Proposed 
paragraph (d)(1) would require that refuse piles (the successor term to 
``coal processing waste banks'') be designed to comply with the 
requirements of 30 CFR 780.28, 816.81, and 816.83. We propose to delete 
the cross-reference to 30 CFR 816.84 found in existing paragraph (d) 
because proposed paragraph (d)(1) would pertain only to refuse piles, 
not to the impounding structures to which 30 CFR 816.84 applies. The 
proposed deletion is not a substantive change because the corresponding 
provision of the existing rules does not pertain to impounding 
structures either, despite the cross-reference. We propose to add the 
cross-reference to 30 CFR 780.28 to emphasize the need for compliance 
with that section whenever a refuse pile would be located in or within 
100 feet of a perennial or intermittent stream.
    Proposed paragraph (d)(2) corresponds to existing paragraph (e), 
which requires that coal processing waste dams and embankments be 
designed to comply with the requirements of 30 CFR 816.81 through 
816.84, among other things. Proposed paragraph (d)(2)(i) would require 
that impounding structures constructed of or intended to impound coal 
mine waste (the successor terminology to ``coal processing waste dams 
and embankments'') be designed to comply with the requirements of 30 
CFR 780.28, 816.81, and 816.84. We propose to delete the cross-
reference to 30 CFR 816.83 found in existing paragraph (e) because 
proposed paragraph (d)(2) would pertain only to impounding structures, 
not to the refuse piles to which 30 CFR 816.83 applies. The proposed 
deletion is not a substantive change because the corresponding 
provision of the existing rules does not pertain to refuse piles 
either, despite the cross-reference. We also propose to add a cross-
reference to the impoundment requirements of 30 CFR 816.49(a) and (c). 
This proposed addition likewise is not a substantive change because 30 
CFR 816.84(b)(1) already includes an identical cross-reference to 30 
CFR 816.49(a) and (c), which would apply by operation of the cross-
reference to 30 CFR 816.84 in proposed paragraph (d)(2)(i). We propose 
to add this cross-reference only as a matter of clarity and ease of 
use.
    Finally, we propose to add the cross-reference to 30 CFR 780.28 to 
emphasize the need for compliance with that section whenever an 
impounding structure constructed of or intended to impound coal mine 
waste would be located in or within 100 feet of a perennial or 
intermittent stream. While coal mine waste impoundments may not be 
retained as permanent impoundments, they typically are converted to 
refuse piles and retained as permanent features, which means that the 
stream segment that they cover is not restored. Hence, proposed 
paragraph (d)(2)(i) and proposed 30 CFR 780.28 would apply the same 
requirements to coal mine waste impoundments as would apply to refuse 
piles with respect to the approval of such structures in perennial or 
intermittent streams.
    Proposed paragraph (d)(2)(ii) would require that the design plan 
for any impounding structure constructed of or intended to impound coal 
mine waste comply with the MSHA requirements of 30 CFR 77.216-2 if the 
structure meets the criteria of 30 CFR 77.216(a). The corresponding 
provision of existing paragraph (e) also required compliance with 30 
CFR 77.216-1. We propose to delete this cross-reference because 30 CFR 
77.216-1 does not include any design requirements. Instead, that rule 
consists solely of MSHA requirements for signage for existing 
impoundments and impoundments under construction. Those requirements 
are not relevant to preparation of plans or permit applications for 
proposed impoundments or impounding structures. Proposed paragraph 
(d)(2)(ii) would retain the requirement that each plan for an 
impounding structure comply with 30 CFR 77.216-2, which contains MSHA 
design requirements for impoundments and impounding structures.
    Proposed paragraph (d)(2)(iii) is substantively identical to the 
corresponding portion of existing paragraph (e), which requires that 
the application include a geotechnical investigation of the foundation 
area and that the investigation be planned and supervised by an 
engineer or engineering geologist. We propose to redesignate existing 
paragraphs (e)(1) through (4), which establish minimum requirements for 
that investigation, as paragraphs (d)(2)(iii)(A) through (D).
    Proposed paragraph (d)(2)(iv) would require that the design ensure 
that at least 90 percent of the water stored in the impoundment during 
the design precipitation event will be removed within a 10-day period. 
This requirement is substantively identical to existing 30 CFR 
816.84(e). We propose to move it to 30 CFR 780.25(d)(2)(iv) as part of 
our ongoing efforts to move permitting requirements currently located 
in subchapter K to subchapter G.
14. Section 780.28: What additional requirements apply to proposed 
activities in, through, or adjacent to streams?
    Proposed 780.28 would establish standards for the review and 
approval of permit applications that propose to conduct surface mining 
activities in or through a perennial, intermittent, or ephemeral stream 
or that would disturb the surface of lands within 100 feet of a 
perennial, intermittent, or ephemeral stream. Consequently, we propose 
to move the permitting aspects of the

[[Page 44514]]

stream buffer zone rule, which is currently codified at 30 CFR 
816.57(a) as part of the performance standards in subchapter K, to 30 
CFR 780.28, which would be part of the permitting requirements of 
subchapter G. Existing 30 CFR 816.57(a) provides that the regulatory 
authority may authorize activities on the surface of lands within 100 
feet of a perennial or intermittent stream only upon finding that (1) 
the activities will not cause or contribute to the violation of 
applicable State or Federal water quality standards and will not 
adversely affect the water quantity and quality or other environmental 
resources of the stream, and (2) if there will be a temporary or 
permanent stream-channel diversion, it will comply with 30 CFR 816.43.
    Part II of this preamble summarizes the impacts of surface coal 
mining operations on streams, as documented by scientific studies. Our 
proposed rule is intended to prevent or minimize the adverse impacts 
documented in those studies.
    The permitting requirements and performance standards in SMCRA 
contain limited direct references to streams, but SMCRA is replete with 
requirements to minimize or prevent adverse impacts on fish, wildlife, 
related environmental values, the quantity and quality of surface water 
and groundwater, and the hydrologic balance. See sections 507(b)(10), 
(11) and (14); 508(a)(9) and (13); 510(b); 515(b)(2), (4), (9), (10), 
(14), (17), and (24); 515(c)(4); 515(e)(3); 516(b)(4); and 516(b)(9) 
through (12).\402\ To the extent that proposed 30 CFR 780.28 pertains 
to the impact of surface coal mining and reclamation operations on 
streams outside the permit area, section 510(b)(3) of SMCRA,\403\ which 
prohibits issuance of a permit unless the applicant demonstrates, and 
the regulatory authority finds, that the proposed operation has been 
designed to prevent material damage to the hydrologic balance outside 
the permit area, provides authority for this proposed rule.

    In addition, section 102 of SMCRA \404\ repeatedly identifies 
environmental protection as one of the purposes of SMCRA. In 
particular, section 102(a) \405\ states that one of the purposes of 
SMCRA is to ``establish a nationwide program to protect society and the 
environment from the adverse effects of surface coal mining 
operations.'' Paragraph (c) \406\ provides that another purpose is to 
``assure that surface mining operations are not conducted where 
reclamation as required by this Act is not feasible.'' Paragraph (d) 
\407\ provides that still another purpose is to ``assure that surface 
coal mining operations are so conducted as to protect the 
environment.'' Paragraph (f) \408\ states that one of the Act's 
purposes is to ``strike a balance between protection of the environment 
and agricultural productivity and the Nation's need for coal as an 
essential source of energy.'' Together with section 201(c)(2) of SMCRA 
\409\ and the provisions of title V of SMCRA discussed below, these 
statutory provisions provide adequate authority for the stream 
protection measures that we propose to adopt in 30 CFR 780.28 to remedy 
the environmental problems identified in Part II of this preamble. 
Section 201(c)(2) of SMCRA \410\ provides that the Secretary of the 
Interior, acting through OSMRE, shall ``publish and promulgate such

    In an en banc ruling, the U.S. Court of Appeals for the District of 
Columbia Circuit upheld the Secretary's authority to promulgate rules 
under the authority of section 201(c) of SMCRA \411\ that impose 
permitting requirements in addition to those set forth in sections 507 
and 508 of SMCRA: \412\ ``We hold that the Act's explicit listings of 
information required of permit applicants are not exhaustive, and do 
not preclude the Secretary from requiring the states to secure 
additional information needed to ensure compliance with the Act.'' 
\413\ The court found that the Secretary's conclusion that additional 
information beyond that explicitly required in the Act was needed to 
effectively implement the Act was entitled to some deference.\414\ 
Furthermore, the U.S. District Court for the District of Columbia has 
held that ``[a] court should sustain regulations when they reasonably 
relate to the purpose of the legislation.'' \415\ The regulations that 
we propose in 30 CFR 780.28 clearly relate to and promote attainment of 
the environmental protection purposes of the Act, as well as the other 
provisions of SMCRA cited above that pertain to protection of fish, 
wildlife, related environmental values, the quantity and quality of 
surface water and groundwater, and the hydrologic balance. The proposed 
regulations also would implement section 515(b)(23) of SMCRA,\416\ 
which provides that surface coal mining and reclamation operations must 
``meet such other criteria as are necessary to achieve reclamation in 
accordance with the purposes of this Act, taking into consideration the 
physical, climatological, and other characteristics of the site.''

    In addition, the measures that we propose to adopt in 30 CFR 780.28 
receive support from section 515(b)(2) of SMCRA,\417\ which requires 
that surface coal mining and reclamation operations ``restore the land 
affected to a condition capable of supporting the uses which it was 
capable of supporting prior to any mining, or higher or better uses of 
which there is a reasonable likelihood.'' Perennial and intermittent 
streams provide important fish and wildlife habitat, which almost 
always is one of the uses that the land was capable of supporting 
before mining. Section 515(b)(10) of SMCRA \418\ also provides 
statutory authority for proposed 30 CFR 780.28. In relevant part, 
section 515(b)(10) of SMCRA requires that surface coal mining and 
reclamation operations ``minimize the disturbances to the prevailing 
hydrologic balance at the mine-site and in associated offsite areas and 
to the quality and quantity of water in surface and ground water 
systems both during and after surface coal mining operations and during 
reclamation by . . . (G) such other actions as the regulatory authority 
may prescribe.''

515(b)(10)(B)(i) of SMCRA,\420\ which, in relevant part, requires that 
surface coal mining operations be conducted ``so as to prevent, to the 
extent possible using the best technology currently available,

[[Page 44515]]

statutory authority for that minimum buffer width. The prohibition on 
disturbing the buffer zone also would implement section 515(b)(24) of 
SMCRA,\421\ which provides that surface coal mining and reclamation 
operations must be conducted to minimize disturbances to and adverse 
impacts on fish, wildlife, and related environmental values to the 
extent possible using the best technology currently available.

Proposed Paragraph (a): Clean Water Act Requirements
    Proposed paragraph (a) would specify that a person may conduct 
surface mining activities in waters of the United States only if that 
person first obtains all necessary authorizations, certifications, and 
permits under the Clean Water Act, 33 U.S.C. 1251 et seq. This proposed 
paragraph is an informational provision that would be consistent with 
section 702(a) of SMCRA,\422\ which provides that ``[n]othing in this 
Act shall be construed as superseding, amending, modifying, or 
repealing'' the Clean Water Act, any rule or regulation adopted under 
the Clean Water Act, or any state laws enacted pursuant to the Clean 
Water Act. Proposed paragraph (a) would operate in tandem with proposed 
30 CFR 773.17(h), which would add a new permit condition requiring that 
the permittee obtain all necessary authorizations, certifications, and 
permits in accordance with Clean Water Act requirements before 
conducting any activities that require approval, authorization, or 
certification under the Clean Water Act. Permit conditions are directly 
enforceable under SMCRA. Therefore, addition of the permit condition in 
proposed 30 CFR 773.17(h) would mean that the SMCRA regulatory 
authority must take enforcement action if the permittee does not obtain 
all necessary Clean Water Act authorizations, certifications, and 
permits before beginning any activity under the SMCRA permit that also 
requires approval or authorization under the Clean Water Act.
---------------------------------------------------------------------------

    \422\ 30 U.S.C. 1292(a).
---------------------------------------------------------------------------

Proposed Paragraph (b): When must I comply with this section?
    Proposed paragraph (b)(1) would apply 30 CFR 780.28 to permit 
applications to conduct surface mining activities in or through a 
perennial, intermittent, or ephemeral stream or on the surface of lands 
within 100 feet, measured horizontally, of perennial or intermittent 
streams.\423\ The 100-foot distance reflects the 100-foot buffer zone 
that 30 CFR 816.57(a) establishes for perennial and intermittent 
streams. The preamble to proposed 30 CFR 816.57(a) explains the 
rationale for the 100-foot buffer zone width. Activities include, but 
are not limited to, mining through or diverting streams; constructing 
sedimentation ponds, excess spoil fills, and coal mine waste disposal 
facilities in or near streams; and constructing stream crossings for 
roads and utilities, as well as the full range of mining and 
reclamation activities that the application may propose to take place 
outside the stream channel but on the surface of lands within 100 feet 
of the stream.
---------------------------------------------------------------------------

    \423\ See the discussion of proposed 30 CFR 780.16(c) in this 
preamble for an explanation of how this distance must be measured.
---------------------------------------------------------------------------

    Proposed paragraph (b)(2), in combination with proposed paragraph 
(e)(2) and 30 CFR 816.57, would prohibit mining-related activities in 
or within 100 feet of perennial and intermittent streams unless the 
applicant demonstrates, and the regulatory authority finds in writing, 
that the proposed activity would not (i) preclude any premining use or 
any designated use under the Clean Water Act of the affected stream 
segment following the completion of mining and reclamation; (ii) result 
in the conversion of the affected stream segment from intermittent to 
ephemeral, from perennial to intermittent, or from perennial to 
ephemeral; (iii) cause or contribute to a violation of water quality 
standards under the Clean Water Act; or (iv) cause material damage to 
the hydrologic balance outside the permit area. Proposed paragraph 
(b)(2)(iv) would duplicate the finding required by 30 CFR 773.15(e). 
Proposed paragraphs (b)(2)(i) through (iii) are similar to subsets of 
the definition of material damage to the hydrologic balance outside the 
permit area, but they differ from the definition of that term and 30 
CFR 773.15(e) in that they would apply within the permit area as well 
as outside it. Proposed paragraphs (b)(2)(i) and (ii) would apply to 
stream segments within the permit area only after the completion of 
mining and reclamation, consistent with section 515(b)(10) of 
SMCRA,\424\ which provides for minimization, not prevention, of 
disturbances to the prevailing hydrologic balance at the minesite.
---------------------------------------------------------------------------

    \424\ 30 U.S.C. 1265(b)(10).
---------------------------------------------------------------------------

    To enhance fish and wildlife habitat, as required by section 
515(b)(24) of SMCRA,\425\ proposed paragraph (b)(3)(i) would require 
that the permit application include plans for establishment of a 
riparian corridor at least 100 feet wide on each side of a perennial, 
intermittent, or ephemeral stream segment \426\ that remains after 
mining or that is restored as part of the reclamation process. The 
preamble to proposed 30 CFR 780.16 explains why we selected the minimum 
100-foot width for the riparian corridor.
---------------------------------------------------------------------------

    \425\ 30 U.S.C. 1265(b)(24).
    \426\ See the discussion of proposed 30 CFR 780.16(c) in this 
preamble for an explanation of how this distance must be measured.
---------------------------------------------------------------------------

    Proposed paragraph (b)(3)(ii) would require that disturbed areas 
within the corridor be planted with native species, including species 
adapted to and suitable for planting in riparian zones within that 
corridor. It also would require use of native trees and shrubs in 
previously forested areas or in areas that would revert to forest under 
conditions of natural succession. Creation of a riparian corridor 
populated with native species is part of the best technology currently 
available to minimize adverse impacts on fish, wildlife, and related 
environmental values and to achieve enhancement of those resources, as 
required by section 515(b)(24) of SMCRA.\427\ Nothing in proposed 
paragraph (b)(3) would require planting of hydrophilic species in 
riparian corridors or portions of riparian corridors that are incapable 
of providing the necessary moisture or other growing conditions. In 
those situations, proposed paragraph (b)(3)(ii) would require that the 
riparian corridor be planted with native species appropriate to the 
conditions.
---------------------------------------------------------------------------

    \427\ 30 U.S.C. 1265(b)(24).
---------------------------------------------------------------------------

    Proposed paragraph (b)(3)(iii) would provide that the proposed 
riparian corridor requirement would not apply to prime farmland 
historically used for cropland because 30 CFR 785.17(e)(1) provides 
that the postmining land use of prime farmland historically used for 
cropland must be cropland. The proposed riparian corridor requirement 
also would not apply to situations in which revegetation would be 
incompatible with an approved postmining land use that is implemented 
during the revegetation responsibility period before final bond 
release. Finally, the riparian corridor requirement would not apply to 
stream segments buried beneath an excess spoil fill or a coal mine 
waste disposal facility pursuant to proposed paragraph (d).
Proposed Paragraph (c): What additional requirements apply to an 
application that proposed to mine through or divert a perennial, 
intermittent, or ephemeral stream?
    Proposed paragraph (c)(1) would require that the proposed 
postmining drainage pattern of perennial,

[[Page 44516]]

intermittent, and ephemeral stream channels to be restored after the 
completion of mining be similar to the premining drainage pattern. In 
addition to its ecological benefits, this requirement would better 
implement the requirement in section 515(b)(3) of SMCRA \428\ that the 
permittee ``restore the approximate original contour of the land.'' The 
proposed rule would allow the regulatory authority to approve 
deviations from the premining drainage pattern when necessary to ensure 
stability, to promote enhancement of fish and wildlife habitat 
consistent with sections 515(b)(24) and 516(b)(11) of SMCRA,\429\ or to 
prevent or minimize excessive downcutting (deepening) of reconstructed 
stream channels. For example, additional meanders may be needed to 
minimize channel erosion and downcutting when restoring streams in 
areas with a badlands-type topography that existed prior to mining.

    \429\ 30 U.S.C. 1265(b)(24) and 1266(b)(11).
---------------------------------------------------------------------------

    Proposed paragraph (c)(2) would establish additional requirements 
for permit applications that propose to mine through or permanently or 
temporarily divert a perennial or intermittent stream. Proposed 
paragraph (c)(2)(i) would reiterate that the applicant must meet the 
requirements of proposed paragraphs (a) through (c)(1). Proposed 
paragraph (c)(2)(ii) would require that the applicant demonstrate that 
there is no reasonable alternative that would avoid mining through or 
diverting the stream. Proposed paragraph (c)(2)(iii) would require that 
the operation be designed to minimize the extent to which the stream 
will be mined through or diverted. Proposed paragraph (c)(2)(iv) would 
require that the applicant demonstrate that the techniques in the 
reclamation plan will restore the form and ecological function of the 
affected stream segment, as required by 30 CFR 816.57(b).
    Proposed paragraph (c)(2)(iv)(A) would require the selective 
placement of aquitards (barriers to groundwater infiltration) within 
the backfill or fill when necessary to restore perennial and 
intermittent streams. Placement of a layer of lower-permeability spoil 
or other material near the surface but below the root zone for trees 
and shrubs could provide the subsurface flow needed to restore flow in 
perennial and intermittent stream segments. Construction of aquitards 
would have the additional benefit of quickly removing water that 
otherwise would have infiltrated the fill and could have emerged as 
leachate with undesirable concentrations of total dissolved solids or 
other parameters that could degrade downstream waters.
    Proposed paragraph (c)(2)(iv)(B) would require that the permit 
application include a separate bond calculation for the costs of 
restoring the ecological function of the stream. It also would require 
that, before permit issuance, the permit applicant post a surety bond, 
a collateral bond, or a combination of surety and collateral bonds to 
cover that cost. A self-bond is not appropriate to guarantee 
restoration of a stream's ecological function because of the risk that 
the company may cease to exist during the time required to accomplish 
that restoration. In addition, a self-bond does not require that the 
permittee file financial instruments or collateral with the regulatory 
authority, nor is there any third party obligated to complete the 
reclamation or pay the amount of the bond if the permittee defaults on 
reclamation obligations.
    Proposed paragraph (c)(2)(v) would require that the applicant 
comply with the stream restoration and stream-channel diversion design 
requirements in existing 30 CFR 816.43. As part of our effort to 
consolidate permitting requirements in subchapter G of our regulations, 
we propose to move the stream-channel diversion design provisions in 
the last sentence of existing 30 CFR 816.43(a)(3) and in paragraphs 
(b)(2) through (b)(4) of existing 30 CFR 816.43 to 30 CFR 
780.28(c)(2)(v) and (vi).
    We also propose to extend the design requirements of proposed 
paragraph (c)(2)(v)(A) and the design certification requirements of 
proposed paragraph (c)(2)(vi) to perennial and intermittent stream 
channels to be restored after the completion of mining. Our existing 
rules do not address restored stream channels, an oversight that we 
propose to correct because there is no legal or scientific basis for 
the absence of standards for the restoration of stream channels. 
Restored stream channels and permanent stream-channel diversions are 
equally important in terms of their value to the fish, wildlife, and 
related environmental values protected by section 515(b)(24) of 
SMCRA.\430\ In addition, there is no legal, technical, or scientific 
reason why designs for restored stream channels should be subject to 
less rigorous certification standards than designs for stream-channel 
diversions.
---------------------------------------------------------------------------

    \430\ 30 U.S.C. 1265(b)(24).
---------------------------------------------------------------------------

    Proposed paragraph (c)(2)(v)(A) would require that designs for 
permanent stream-channel diversions, temporary stream-channel 
diversions that will be in use for 2 or more years, and stream channels 
that are to be restored after the completion of mining replicate or 
approximate the premining characteristics of the original stream 
channel to promote the recovery and enhancement of the aquatic habitat 
and to minimize adverse alteration of stream channels on and off the 
site, including channel deepening or enlargement. This provision is 
similar to the last sentence of existing 30 CFR 816.43(a)(3), with a 
few exceptions.
    First, the existing rule applies only to permanent stream-channel 
diversions. Applying the design requirements of proposed paragraph 
(c)(2)(v)(A) to temporary stream-channel diversions that will be in use 
for 2 or more years would reduce the damage to aquatic resources caused 
by temporary diversions that remain in use for extended periods, 
consistent with the requirement in section 515(b)(24) of SMCRA \431\ to 
minimize adverse impacts on fish, wildlife, and related environmental 
values to the extent possible, using the best technology currently 
available. In recognition of the shorter lifespan of temporary 
diversions, we propose to specify that, for temporary stream-channel 
diversions that will remain in use for 2 or more years, the vegetation 
proposed for planting in the riparian zone need not include species 
that would not reach maturity until after the diversion is removed. In 
other words, faster-growing species like willows, alders, and poplars 
or early successional natural riparian vegetation would be acceptable.
---------------------------------------------------------------------------

    \431\ Id.
---------------------------------------------------------------------------

    Second, proposed paragraph (c)(2)(v)(A) would specify that the 
premining characteristics of the original stream channel include, but 
are not limited to, the baseline stream pattern, profile, dimensions, 
substrate, habitat, and natural vegetation growing in the riparian 
zone. The addition of this clarification is intended to make our 
regulations more consistent with similar requirements under section 404 
of the Clean Water Act and its implementing regulations. It also would 
minimize adverse impacts on fish, wildlife, and related environmental 
values to the extent possible, using the best technology currently 
available, as required by section 515(b)(24) of SMCRA.\432\
---------------------------------------------------------------------------

    \432\ Id.
---------------------------------------------------------------------------

    Third, proposed paragraph (c)(2)(v)(A) would specify that the 
design must minimize adverse alteration of stream channels on and off 
the site, including channel deepening or enlargement. This provision 
would minimize adverse impacts on fish, wildlife, and related

[[Page 44517]]

environmental values to the extent possible, using the best technology 
currently available, as required by section 515(b)(24) of SMCRA,\433\ 
because channel deepening or enlargement can reduce the frequency and 
volume of flows over the flood-plain and contribute sediment to 
streamflow and streambeds through streambank erosion.
---------------------------------------------------------------------------

    \433\ Id.
---------------------------------------------------------------------------

    Proposed paragraph (c)(2)(v)(B) would require that the stream-
channel design ensure that the hydraulic capacity of all temporary and 
permanent stream-channel diversions is at least equal to the hydraulic 
capacity of the unmodified stream channel immediately upstream from the 
diversion and no greater than the hydraulic capacity of the unmodified 
stream channel immediately downstream from the diversion. Existing 30 
CFR 816.43(b)(2) applies the same standard for the hydraulic capacity 
of the diversion both upstream and downstream of the diversion; i.e., 
the designed hydraulic capacity of the diversion must be at least equal 
to the hydraulic capacity of the unmodified stream channel immediately 
upstream and downstream from the diversion. Our proposal to require 
that the designed hydraulic capacity of the diversion be no greater 
than (rather than at least equal to) the hydraulic capacity of the 
unmodified stream channel immediately downstream from the diversion 
would protect against the scouring and other adverse impacts that could 
result from a sudden constriction in channel capacity if the diversion 
was allowed to exceed the capacity of the unmodified stream channel 
downstream of the diversion. Therefore, proposed paragraph (c)(2)(v)(B) 
would be consistent with the requirement in section 515(b)(24) of SMCRA 
\434\ to minimize adverse impacts on fish, wildlife, and related 
environmental values to the extent possible, using the best technology 
currently available.
---------------------------------------------------------------------------

    \434\ Id.
---------------------------------------------------------------------------

    Proposed paragraph (c)(2)(v)(C) would require that all temporary 
and permanent stream-channel diversions be designed so that the 
combination of channel, bank, and flood-plain configuration is adequate 
to pass safely the peak runoff of a 10-year, 6-hour precipitation event 
for a temporary diversion and a 100-year, 6-hour precipitation event 
for a permanent diversion. Proposed paragraph (c)(2)(v)(C) is 
substantively identical to existing 30 CFR 816.43(b)(3). We invite 
comment on whether the design event for a temporary diversion should be 
raised to the 25-year, 6-hour event to provide added safety and 
protection against overtopping.
    Proposed paragraph (c)(2)(vi) would require submission of a 
certification from a qualified registered professional engineer that 
the designs for all stream-channel diversions and all stream channels 
to be restored after the completion of mining meet the design 
requirements of 30 CFR 780.28 and any additional design criteria 
established by the regulatory authority. Our proposed rule differs from 
the design certification elements of existing 30 CFR 816.43(b)(4) in 
that we propose to expand the design certification requirement to apply 
to all stream channels to be restored after the completion of mining, 
not just to stream-channel diversions as in the existing rule. As 
discussed above, there is no legal, technical, or scientific reason to 
apply less rigorous design and certification requirements to restored 
stream channels than to permanent stream-channel diversions. In 
addition, we propose to require that the engineer certify that the 
design meets the design requirements of 30 CFR 780.28, not the 
performance standards as in the existing rule, because performance 
standards do not apply directly to designs. Finally, we propose to 
specify that the certification may be limited to the location, 
dimensions, and physical characteristics of the stream channel; it need 
not include restoration of ecological function, which may be beyond the 
professional competency of an engineer.
Proposed Paragraph (d): What requirements apply to an application to 
construct an excess spoil fill or coal mine waste disposal facility in 
a perennial or intermittent streams?
    Proposed paragraph (d)(1) would apply the requirements of proposed 
paragraph (d)(2) in place of the requirements of proposed paragraph 
(b)(2) if the applicant proposes to construct an excess spoil fill or 
coal mine waste disposal facility that would encroach upon any part of 
a perennial or intermittent stream. We are proposing paragraph (d) 
because we recognize that some of the requirements of proposed 
paragraph (b)(2) that would apply to activities in streams cannot be 
met with respect to a stream segment that is buried underneath an 
excess spoil fill or a coal mine waste disposal facility.
    A permit application that contains a proposal to construct an 
excess spoil fill or a coal mine waste disposal facility that would not 
encroach upon any part of a perennial or intermittent stream would not 
be subject to the requirements of proposed paragraph (d)(2). However, 
if the proposed fill or disposal facility would disturb the surface of 
land within 100 feet of a perennial or intermittent stream,\435\ the 
application would have to comply with the requirements of proposed 
paragraph (b)(2).
---------------------------------------------------------------------------

    \435\ See the discussion of proposed 30 CFR 780.16(c) in this 
preamble for an explanation of how this distance must be measured.
---------------------------------------------------------------------------

    Proposed paragraph (d)(2) would identify the demonstrations that a 
permit application must include if the applicant proposes to construct 
an excess spoil fill or coal mine waste disposal facility in a 
perennial or intermittent stream. The legal authority for the proposed 
demonstration requirements is set forth in detail in the introductory 
paragraphs of the discussion of proposed 30 CFR 780.28 in this preamble 
and will not be repeated here. The demonstrations that we propose to 
require are a combination of other regulatory program and Clean Water 
Act requirements; measures that constitute the best technology 
currently available to minimize any adverse impacts on fish, wildlife, 
and related environmental values, as required by section 515(b)(24) of 
SMCRA; \436\ and fish and wildlife enhancement measures intended to 
offset any unavoidable long-term damage to fish, wildlife, and related 
environmental values.
---------------------------------------------------------------------------

    \436\ Id.
---------------------------------------------------------------------------

    Proposed paragraph (d)(2)(i) would require that the applicant 
demonstrate that the operation has been designed to minimize the amount 
of excess spoil or coal mine waste generated, which would have the 
effect of minimizing the need for or the size of the excess spoil fill 
or coal mine waste disposal facility. This finding corresponds to 
proposed 30 CFR 780.35(b) for excess spoil. For coal mine waste, this 
finding in essence would require a description of the steps taken to 
minimize the amount of coal mine waste generated by the coal 
preparation process, such as the use of filter presses, or an 
explanation of why minimization measures are not practicable.
    Proposed paragraph (d)(2)(ii) would require that the applicant 
demonstrate that, after evaluating all potential upland locations in 
the vicinity of the proposed operation, there is no practicable 
alternative that would avoid placement of excess spoil or coal mine 
waste in a perennial or intermittent stream. Potential upland locations 
that must be considered include, but are not limited to, abandoned mine 
lands and existing fills with excess capacity. The application must 
identify potential locations such as the examples

[[Page 44518]]

mentioned above and explain why those locations are not suitable or 
practicable. We anticipate that, for excess spoil, the permit applicant 
and regulatory authority would conduct this analysis in a manner 
similar to that described in Kentucky Reclamation Advisory Memorandum 
(RAM) 145, which establishes a fill placement optimization process for 
steep-slope mining in Kentucky.\437\ For coal mine waste, the 
application would have to explain why an alternative configuration, 
location, or coal mine waste disposal method is not practicable.

---------------------------------------------------------------------------

    Proposed paragraph (d)(2)(iii) would require that the applicant 
demonstrate that, to the extent possible using the best technology 
currently available, the proposed excess spoil fill or coal mine waste 
disposal facility has been designed to minimize both placement of 
excess spoil or coal mine waste in a perennial or intermittent stream 
and adverse impacts on fish, wildlife, and related environmental 
values. This provision corresponds in part to the fill optimization 
requirements of proposed 30 CFR 780.35(c). We anticipate that the RAM 
145 process mentioned above may assist in meeting this requirement. 
Proposed paragraph (d)(2)(iii) would implement, in part, section 
515(b)(24) of SMCRA,\438\ which provides that surface coal mining and 
reclamation operations must be conducted to minimize disturbances and 
adverse impacts on fish, wildlife, and related environmental values to 
the extent possible, using the best technology currently available.

    Proposed paragraph (d)(2)(iv) would require that the applicant 
demonstrate that the fish and wildlife enhancement plan for the 
proposed operation includes measures that would fully and permanently 
offset any long-term adverse impacts that the fill, refuse pile, or 
coal mine waste impoundment would have on fish, wildlife, and related 
environmental values within the footprint of the fill, refuse pile, or 
coal mine waste impoundment. The regulatory authority would determine 
the meaning of ``fully and permanently offset'' on a case-by-case 
basis. At a minimum, riparian corridors must be protected by 
conservation easements (dedicated to an appropriate agency or 
organization) or deed restrictions so that the newly planted vegetation 
is not destroyed after bond release. We invite comment on whether the 
final rule could or should include more specific standards or criteria 
for determining the meaning of ``fully and permanently offset.'' We 
also invite comment on whether mitigation required pursuant to section 
404 of the Clean Water Act \439\ may satisfy this requirement and 
whether past Clean Water Act mitigation measures have been successful. 
We encourage submission of data to document the success or failure of 
those measures.

facility has been designed in a manner that will not cause or 
contribute to a violation of water quality standards or result in the 
formation of toxic mine drainage. The demonstration that this paragraph 
would require is intended to ensure the proposed operation will not 
cause material damage to the hydrologic balance outside the permit 
area. In particular, it is intended to ensure that discharges to 
surface water or groundwater from the excess spoil fill or coal mine 
waste disposal facility would not have a substantial adverse impact on 
water quality or aquatic biota in receiving streams. As defined in 30 
CFR 701.5, toxic mine drainage means any discharge that ``contains a 
substance that through chemical or physical effects is likely to kill, 
injure, or impair biota commonly present in that area that might be 
exposed to it.''
    Proposed paragraph (d)(2)(vi) would require that the applicant 
demonstrate that the revegetation plan submitted under proposed 30 CFR 
780.12(g) requires reforestation of a completed excess spoil fill if 
the land is forested at the time of application or if it would revert 
to forest under conditions of natural succession. This measure is 
intended to minimize the adverse impacts of the fill on watershed 
hydrology, especially the quantity and quality of surface runoff, and 
aquatic life in the stream.
    Proposed Paragraph (e): What are the regulatory authority's 
responsibilities?
    Proposed paragraph (e)(1)(i) would require that the regulatory 
authority establish objective standards for determining when the 
ecological function of a restored or permanently-diverted perennial or 
intermittent stream has been restored. Objective standards are 
essential to fair enforcement of the requirement for restoration of the 
ecological function of streams and to enable permit applicants to 
develop appropriate and comprehensive reclamation plans. Proposed 
paragraph (e)(1)(ii) would require that, in establishing these 
standards, the regulatory authority coordinate with the Clean Water Act 
permitting authority to ensure compliance with all Clean Water Act 
requirements.
    Proposed paragraph (e)(1)(iii) would specify that the standards 
established by the regulatory authority must comply with the functional 
restoration requirements of proposed 30 CFR 816.57(b)(2). In relevant 
part, proposed 30 CFR 816.57(b)(2) would require that a stream flowing 
through a restored stream channel or stream-channel diversion have a 
biological condition adequate to support the designated uses of the 
original stream segment under section 101(a) or 303(c) of the Clean 
Water Act \440\ before mining. This provision may allow limited changes 
in the species composition of the array of insects, fish, and other 
aquatic organisms found in a stream flowing through a restored stream 
channel or stream-channel diversion, as long as the changes do not 
preclude existing uses or attainment of designated uses. Proposed 30 
CFR 816.57(b)(2) also would require that the biological condition of 
the restored stream be determined using a protocol that meets the 
requirements of proposed 30 CFR 780.19(e)(2) and that populations of 
organisms used to determine the postmining biological condition of the 
stream segment be self-sustaining within that segment. We propose to 
include this provision because the presence of individual organisms 
that happen to drift into the reconstructed channel from other areas is 
not an indicator of restoration of the ecological function of the 
restored stream segment.

    Proposed paragraph (e)(2) specifies that the regulatory authority 
may not approve an application that includes any activities included in 
proposed paragraph (a)(1) unless the regulatory authority first makes a 
written finding that the applicant has fully satisfied all applicable 
requirements of 30 CFR 780.28. It also would require that the finding 
be accompanied by a detailed explanation and rationale for the finding. 
These requirements are appropriate, given the purposes and provisions 
of SMCRA discussed in the introductory paragraphs of the preamble to 30 
CFR 816.57 and the typically high value of perennial and intermittent 
streams to fish and wildlife.

15. Section 780.29: What information must I include in the surface-
water runoff control plan?
    We propose to revise this section to require that each application 
include a surface-water runoff control plan. We propose to require this 
plan because uncontrolled surface-water runoff can and has been known 
to cause flooding downgradient of the operation, which in turn can 
result in material damage to the hydrologic balance outside the permit 
area, property damage, and loss of human life, as well as adverse 
impacts on fish, wildlife, and related environmental values. Section 
510(b)(3) of SMCRA \441\ provides that the regulatory authority may not 
approve a permit application unless the application affirmatively 
demonstrates and the regulatory authority finds in writing that the 
proposed operation has been designed to prevent material damage to the 
hydrologic balance outside the permit area. Section 515(b)(24) of SMCRA 
\442\ requires that surface coal mining and reclamation operations 
minimize adverse impacts on fish, wildlife, and related environmental 
values.

---------------------------------------------------------------------------

    Proposed paragraph (a)(1) specifies that the plan must explain how 
surface-water runoff will be handled in a manner that will prevent peak 
discharges from the proposed permit area, both during and after mining 
and reclamation, from exceeding premining peak discharges from the same 
area for the same-size precipitation event. Proposed paragraph (a)(1) 
also requires use of the appropriate regional NRCS synthetic storm 
distribution to estimate peak discharges. Design criteria for hydraulic 
structures intended to handle overland flow from precipitation events 
are based in part on the peak runoff rate and/or runoff volume from the 
area draining to the structure. Actual precipitation records for small 
drainage areas generally are not available, so engineers typically rely 
upon mathematical models instead. The distribution of rainfall 
intensities is one of the primary inputs to those models. We propose to 
require use of the appropriate regional NRCS synthetic storm 
distribution to determine runoff intensities and peak flows because it 
is a widely accepted, prudent engineering design methodology.
    Maximum runoff from a drainage area occurs when the peak intensity 
of the rainfall event coincides with the time of concentration (the 
length of time between the beginning of the rainfall event and the time 
when runoff from the entire drainage area first arrives at the outlet 
for the drainage area). Typically, for precipitation events with the 
same return interval (2 years, 10 years, 100 years, etc.), peak 
intensity is much greater for storms of short duration--the shorter the 
duration, the greater the maximum intensity and the greater the amount 
of peak flow from surface runoff. Traditionally, peak stormwater runoff 
from a drainage area was determined using a storm duration 
approximately 1.7 times greater than the time of concentration. Use of 
the NRCS synthetic storm distribution accomplishes this determination 
automatically. For example, precipitation intensity during the 1-hour 
or 6-hour increment with the highest rainfall amount within the 24-hour 
10-year synthetic distribution (theoretical storm event) is identical 
to precipitation intensity and total rainfall during traditional 1-hour 
and 6-hour 10-year events. Therefore, it is not necessary to select a 
storm duration related to the time of concentration to capture the 
greater intensities of events of shorter duration.
    Proposed paragraph (a)(2) specifies that the explanation in 
paragraph (a)(1) must consider the findings in the PHC determination 
prepared under Sec.  780.20.
    Proposed paragraph (b) would require that the plan include a 
surface-water runoff monitoring and inspection program that would 
provide sufficient precipitation and stormwater discharge data for the 
proposed permit area to evaluate the effectiveness of surface-water 
runoff control practices. The surface-water runoff monitoring and 
inspection program must specify criteria for monitoring, inspection, 
and reporting consistent with 30 CFR 816.34(d), which contains the 
corresponding performance standards. The program must contain a 
monitoring point density that adequately represents the drainage 
pattern and drainage distribution across the entire proposed permit 
area, with a minimum of one monitoring point for each watershed 
discharge point. We invite comment on whether the proposed minimum 
monitoring point density standard is too high or too low.
    Proposed paragraph (c) would require that the permit application 
include descriptions, maps, and cross-sections of all runoff control 
structures, including diversions and other channels used to collect and 
convey surface-water runoff. Existing 30 CFR 780.29 applies this 
requirement only to diversions, which, under 30 CFR 816.43, could be 
construed as excluding channels constructed to collect and convey 
surface runoff from the area to be disturbed by the mining operations. 
Under proposed paragraph (c), all such channels would have to be 
designed in accordance with the standards in 30 CFR 816.43. Proposed 
paragraph (c) is intended to ensure that these channels are safe, 
stable, and of adequate capacity.
16. Section 780.35: What information must I provide concerning the 
minimization and disposal of excess spoil?
    We propose to revise, reorganize, and expand our existing rules 
governing permitting requirements for the disposal of excess spoil.
Background and Rationale for the Proposed Rule Changes
    Disposal of excess spoil and coal mine waste often involves the 
filling of substantial portions of stream valleys, especially in 
central Appalachia. Based upon our regulatory experience, updated 
science, and modern engineering practices, we propose to revise our 
regulations to minimize the creation of excess spoil and to ensure that 
excess spoil fills and coal mine waste disposal facilities are located 
and designed to minimize disturbances and adverse impacts on fish, 
wildlife, and related environmental values to the extent possible, 
using the best technology currently available, as required by sections 
515(b)(24) and 516(b)(11) of SMCRA.\443\
---------------------------------------------------------------------------

    \443\ 30 U.S.C. 1265(b)(24) and 1266(b)(11).
---------------------------------------------------------------------------

    Our existing regulations pertaining to the disposal of excess spoil 
primarily focus on ensuring that fills are safe and stable. We propose 
to add several requirements intended to promote environmental 
protection, including minimization of the adverse environmental impacts 
of fill construction in perennial and intermittent streams. We 
recognize that section 515(b)(22) of SMCRA,\444\ which establishes 
standards for the disposal of excess spoil, does not include any 
requirements specifically oriented toward environmental protection, but 
instead focuses on engineering standards intended to promote stability, 
prevent mass movement, and control infiltration of water. However, 
section 515(b)(24) of SMCRA \445\ does require that surface coal mining 
and reclamation operations be conducted in a manner that minimizes 
disturbances to, and adverse impacts on, fish, wildlife, and related 
environmental values to the extent possible, using the

[[Page 44520]]

best technology currently available. Section 515(b)(24) \446\ applies 
to the disposal of excess spoil both by its own terms (disposal of 
excess spoil is a part of surface coal mining and reclamation 
operations) and through section 515(b)(22)(I),\447\ which requires that 
the placement of excess spoil meet ``all other provisions of this 
Act.'' SMCRA contains numerous environmental protection requirements 
that apply to all surface coal mining and reclamation operations and 
all aspects of those operations, including the disposal of excess 
spoil. The fact that section 515(b)(22) \448\ does not mention 
environmental protection in no way suggests that excess spoil fills 
need not comply with the environmental protection provisions of SMCRA 
or that we lack the authority to adopt regulations establishing 
environmental protection requirements for those structures.

    The goal of the excess spoil minimization and fill size 
optimization requirements of proposed paragraphs (b) and (c) is to 
minimize fill footprints and thus minimize disturbances of forests, 
perennial and intermittent streams, and riparian vegetation, consistent 
with the requirement in sections 515(b)(24) and 516(b)(11) of SMCRA 
\449\ to minimize disturbances and adverse impacts on fish, wildlife, 
and related environmental values to the extent possible using the best 
technology currently available.

---------------------------------------------------------------------------

    As part of our oversight activities, we conducted studies in 1999 
in Kentucky, Virginia, and West Virginia to determine how state 
regulatory authorities were administering SMCRA regulatory programs 
regarding restoration of approximate original contour. From our review 
of permit files and reclaimed mines, we determined that, typically, 
some of the spoil placed in excess spoil fills could have been retained 
on or returned to mined-out areas. See ``An Evaluation of Approximate 
Original Contour and Postmining Land Use in Kentucky'' (OSMRE, 
September 1999); ``An Evaluation of Approximate Original Contour 
Variances and Postmining Land Uses in Virginia'' (OSMRE, September 
1999); and ``Final Report: An Evaluation of Approximate Original 
Contour and Postmining Land Use in West Virginia'' (OSMRE, May 1999).
    In many instances, we found that the permit application 
overestimated the anticipated volume of excess spoil that the operation 
would produce. In addition, fills were designed and constructed larger 
than necessary to accommodate the anticipated excess spoil, which 
resulted in the unnecessary disturbance of additional land. Kentucky, 
Virginia, and West Virginia worked with us to develop enhanced guidance 
on material balance determinations, spoil management, and approximate 
original contour determinations to correct these problems to the extent 
feasible under the existing regulations. The regulatory authorities in 
those states have adopted policies based on that guidance for use in 
reviewing permit applications.\450\ We also developed guidance for use 
under the Tennessee federal regulatory program.\451\

---------------------------------------------------------------------------

    If adopted, the rule that we are proposing today would provide 
further authority for the policies in place in Kentucky, Tennessee, 
Virginia, and West Virginia. It would strengthen the enforceability of 
decisions based on those policies and provide national consistency by 
ensuring that certain basic requirements will be applied nationwide, 
including in those states that have not adopted such policies. The 
environment, the public, and the regulated community are best served by 
the adoption of national regulations to clarify environmental 
considerations concerning the generation and disposal of excess spoil.
    Proposed Paragraph (a): Applicability.
    This proposed paragraph would clarify that the provisions of 30 CFR 
780.35 apply only to permit applications that propose to generate 
excess spoil.
Proposed Paragraph (b): Demonstration of Minimization of Excess Spoil
    Proposed paragraph (b)(1) would require a demonstration, with 
supporting calculations and other documentation, that the operation has 
been designed to minimize, to the extent possible, the volume of excess 
spoil that the operation will generate. Designing the operation in this 
fashion should ensure that the maximum amount of overburden is returned 
to the mined-out area. Our goal is to ensure that the volume of 
overburden placed in excess spoil fills is minimized to the maximum 
extent possible. Minimizing the volume of overburden placed in excess 
spoil fills is critical to minimizing the amount of undisturbed land 
affected by fill construction and to ensuring that those fills bury or 
otherwise impact the shortest length of stream possible.
    Proposed paragraph (b)(2) would specify the factors that the permit 
applicant and the regulatory authority must consider in determining 
whether the proposed operation has been designed to minimize the 
creation of excess spoil to the extent possible. It requires 
consideration of safety and stability needs and requirements; 
revegetation and postmining land use needs and requirements; the need 
for drainage structures, access roads, and berms; applicable 
regulations concerning backfilling, compaction, grading, and 
restoration of the approximate original contour; and other relevant 
regulatory requirements, in particular those pertaining to protection 
of water quality and fish, wildlife, and related environmental values. 
Some or all of those factors may limit the amount of spoil that can be 
returned to the mined-out area, especially the requirements related to 
safety, stability, and postmining land use. Also, if the regulatory 
authority does not approve the proposed postmining land use, the 
applicant and the regulatory authority would need to revisit the 
demonstration to determine whether it must be revised to reflect the 
needs and attributes of the postmining land use that is finally 
approved.
    In addition, proposed paragraph (b)(2)(iii) would specify that 
drainage structures, access roads, and berms on the perimeter of the 
backfilled area must not exceed a total width of 20 feet unless the 
permit applicant can demonstrate a need for a greater width. This 
restriction would maximize placement of overburden material on the 
mined-out area and minimize the generation and placement of excess 
spoil. In many cases, construction of access roads or drainage controls 
wider or larger than necessary prevents maximum spoil placement within 
the mined-out area, thus creating larger excess spoil fills and burial 
of a greater length of perennial or intermittent stream segments than 
absolutely necessary. We propose to select 20 feet as the maximum width 
because that is the typical width of a drainage bench on the face of a 
fill or embankment. Twenty feet should provide adequate room for 
drainage and sediment controls during the period between final grading 
and establishment of vegetation. Twenty feet also would afford adequate 
access for equipment in the event that maintenance is required before 
final bond release. We seek comment on

[[Page 44521]]

whether the maximum width should be larger or smaller than 20 feet.
    To attain the goal of minimizing both the amount of land disturbed 
and the length of perennial and intermittent stream segments buried or 
otherwise adversely affected, proposed paragraph (b)(3) would clarify 
that premining elevations do not operate as a cap on the elevation of 
backfilled areas. Instead, the final elevation would be determined on 
the basis of the factors listed in proposed 30 CFR 780.35(b)(2), 
together with the requirement that the final surface configuration be 
compatible with the surrounding terrain and be consistent with natural 
premining landforms. For the same reason, proposed paragraph (b)(4) 
would prohibit the creation of a final-cut impoundment under 30 CFR 
816.49(b) or the placement of coal combustion residues or noncoal 
materials in the mine excavation if doing so would displace spoil 
removed from the excavation to the extent that the displaced mine spoil 
would have to be placed in an excess spoil fill.
Proposed Paragraph (c): Fill Capacity Demonstration
    Proposed paragraph (c) would require that the application include a 
demonstration, with supporting calculations and other documentation, 
that the designed maximum cumulative volume of all proposed excess 
spoil fills within the permit area is no larger than the capacity 
needed to accommodate the anticipated cumulative volume of excess spoil 
that the operation will generate, as calculated under paragraph (b). 
This requirement is intended to prohibit the practice of designing an 
operation with a larger number and greater size of excess spoil fills 
than necessary and then constructing only part of each fill. This 
practice results in the filling of a greater length of stream than 
would be necessary if each fill was used to its maximum capacity, 
especially when using a bottom-up method of fill construction in which 
the entire footprint of the fill is disturbed either before or shortly 
after initial placement of excess spoil in the fill. Adoption of 
proposed paragraph (c) would minimize the adverse impacts of the 
operation on fish, wildlife, and related environmental values, as 
required by section 515(b)(24) of SMCRA,\452\ by minimizing the amount 
of land and water disturbed to construct excess spoil fills.
---------------------------------------------------------------------------

    \452\ 30 U.S.C. 1265(b)(24).
---------------------------------------------------------------------------

Proposed Paragraph (d): Requirements Related to Perennial and 
Intermittent Streams
    Proposed paragraph (d) would specify that a permit applicant 
proposing to construct an excess spoil fill in or within 100 feet of a 
perennial or intermittent stream \453\ must comply with the 
requirements of proposed 30 CFR 780.28 concerning activities in or near 
perennial or intermittent streams.
---------------------------------------------------------------------------

    \453\ See the discussion of proposed 30 CFR 780.16(c) in this 
preamble for an explanation of how this distance must be measured.
---------------------------------------------------------------------------

Proposed Paragraph (e): Location
    Proposed paragraph (e)(1) would require that a permit applicant 
submit maps and cross-section drawings or models showing the location 
and profile of all proposed excess spoil fills. This requirement 
corresponds to the first sentence of existing paragraph (a), which we 
propose to modernize to allow the use of models at the discretion of 
the permit applicant and the regulatory authority. Models can be more 
detailed than either maps or cross-sections. We also propose to require 
that the application include a profile of each excess spoil fill so 
that the regulatory authority is able to determine whether the 
completed fill would meet all applicable surface configuration 
requirements.
    Proposed paragraph (e)(2) would specify that fills must be located 
on the most moderately sloping and naturally stable areas available. It 
also would specify that the regulatory authority will determine which 
areas are available for excess spoil fill construction after 
considering other requirements of the Act and the regulatory program. 
This paragraph corresponds to part of existing 30 CFR 816.71(c), which 
we propose to move to 30 CFR 780.35 because it is a permitting 
requirement, not a performance standard. We propose to add the 
provision specifying that the regulatory authority will determine which 
areas are available for excess spoil fill construction to improve 
consistency with section 515(b)(22)(E) of SMCRA,\454\ which requires 
that excess spoil be placed ``upon the most moderate slope among those 
upon which, in the judgment of the regulatory authority, the spoil 
could be placed in compliance with all the requirements of the Act.'' 
Because one of the requirements of the Act is the provision in section 
515(b)(24) \455\ specifying that surface coal mining and reclamation 
operations must be conducted so as to minimize disturbances and adverse 
impacts on fish, wildlife, and related environmental values to the 
extent possible, using the best technology currently available, the 
location with the most moderate slopes in the vicinity of the proposed 
operation may not be available if construction of the fill at that 
location would have greater adverse impact on fish, wildlife, and 
related environmental values than would construction of the fill at a 
different location with steeper slopes. In other words, the requirement 
to place excess spoil on the most moderate slope is subordinate to 
compliance with other requirements of the Act and regulatory program.

    \455\ 30 U.S.C. 1265(b)(24).
---------------------------------------------------------------------------

    Proposed paragraph (e)(3) provides that, whenever possible, the 
permit applicant must place fills on or above a natural terrace, bench, 
or berm if that location would provide additional stability and prevent 
mass movement. This paragraph corresponds to the remainder of existing 
30 CFR 816.71(c), which we propose to move to 30 CFR 780.35 because it 
is a permitting requirement, not a performance standard. Proposed 
paragraph (e)(3) is consistent with section 515(b)(22)(E) of 
SMCRA,\456\ which requires that excess spoil be placed ``where 
possible, upon, or above, a natural terrace, bench, or berm, if such 
placement provides additional stability and prevents mass movement.'' 
However, spoil placement upon or above a natural terrace, bench, or 
berm may not always be possible because section 515(b)(24) of SMCRA 
\457\ provides that surface coal mining and reclamation operations must 
minimize disturbances and adverse impacts on fish, wildlife, and 
related environmental values to the extent possible, using the best 
technology currently available. Implementation of that requirement may 
entail placement of spoil in a location other than on or above a 
natural terrace, bench, or berm, provided the alternative location is 
stable and would have lesser overall adverse impacts on fish, wildlife, 
and related environmental values.

Proposed Paragraph (f): Design Plans
    Proposed paragraph (f) requires that an application for an 
operation that would generate excess spoil include detailed design 
plans for each excess spoil fill, prepared in accordance with the 
requirements of proposed 30 CFR 780.35 and 816.71 through 816.74. 
Proposed paragraph (f) corresponds to the portion of existing 30 CFR 
780.35(a) that requires that the design comply with 30 CFR 816.71 
through 816.74. For

[[Page 44522]]

clarity and completeness, we propose to add language also requiring 
compliance with the requirements of 30 CFR 780.35, although those 
design requirements would apply anyway in the absence of this 
provision. Proposed paragraph (f) also would require that the applicant 
design the fill and appurtenant structures using current prudent 
engineering practices and any additional design criteria established by 
the regulatory authority. That requirement appears in the first 
sentence of existing 30 CFR 816.71(b)(1), which we propose to move to 
30 CFR 780.35 because it is a design requirement, not a performance 
standard.
Proposed Paragraph (g): Geotechnical Investigation
    Proposed paragraph (g) would require that the application include 
the results of a geotechnical investigation, with supporting 
calculations and analyses, of the site of each proposed excess spoil 
fill, with the exception of those sites at which spoil will be placed 
only on a preexisting bench under 30 CFR 816.74. This provision 
corresponds to existing paragraph (b). We propose to add a requirement 
that the applicant submit supporting calculations and analyses with the 
geotechnical investigation of the site of each proposed excess spoil 
fill. The additional data is essential for the permit application 
reviewer to determine the stability of the proposed design.
    Proposed paragraphs (g)(1) through (6) identify information that 
would have to be submitted with the application to document the 
geotechnical investigation and its results.
    Proposed paragraph (g)(1) would require sufficient foundation 
investigations, as well as any necessary laboratory testing of 
foundation material, to determine the design requirements for 
foundation stability for the site of each fill. This requirement 
currently appears in existing 30 CFR 816.71(d)(1). We propose to move 
it to 30 CFR 780.35(g) consistent with our effort to consolidate design 
requirements in the permitting rules rather than splitting them between 
the permitting rules and the performance standards. The foundation 
investigation is an element of the geotechnical investigation that is 
required for approval of a proposed excess spoil fill in a permit 
application.
    Proposed paragraphs (g)(2) through (6) correspond to, and are 
substantively identical to, existing paragraphs (b)(1) through (5), 
except as discussed below.
    We propose to revise paragraph (g)(3) to require that the applicant 
provide the geographic coordinates and a narrative description, rather 
than just a survey, of all springs, seepage, mine discharges, and 
groundwater flow observed or anticipated during wet periods in the area 
of the proposed fill. The added precision will assist the regulatory 
authority in evaluating the adequacy of the excess spoil fill design.
    Proposed paragraph (g)(4) would require that the applicant provide 
an analysis of the potential effects of any underground mine workings 
within the proposed permit and adjacent areas, including the effects of 
any subsidence that may occur as a result of previous, existing, and 
future underground mining operations. The proposed requirement is 
similar to the portion of existing 30 CFR 816.71(d)(1) that requires 
that the analyses of foundation conditions take into consideration the 
effect of underground mine workings, if any, upon the stability of the 
fill and appurtenant structures. Existing 30 CFR 780.35(b)(3) also 
requires a survey of the potential effects of subsidence that may occur 
as a result of past and future underground mining operations. Our 
proposed revisions would require that the analysis also consider the 
potential effects of subsidence from existing underground mining 
operations, not just past and future operations. The design needs to be 
capable of withstanding all potential impacts of any subsidence that 
may occur during the life of the proposed structure. We propose to add 
the reference to the proposed permit and adjacent areas to ensure that 
the analysis includes all operations that have the potential to cause 
subsidence that may affect the proposed fill, not just operations 
within the proposed permit area.
    Proposed paragraph (g)(6) is substantively identical to existing 
paragraph (b)(5), with the exception that we propose to revise this 
paragraph to clarify that the stability analyses that it requires must 
address static, seismic, and post-earthquake (liquefaction) conditions 
because those conditions are all part of a comprehensive stability 
analysis.
Proposed Paragraph (h): Operation and Reclamation Plans
    Proposed paragraph (h) would require that the permit applicant 
submit plans for the construction, operation, maintenance, and 
reclamation of all excess spoil fills in accordance with the 
requirements of Sec. Sec.  816.71 through 816.74. This requirement 
corresponds to a similar provision in existing paragraph (a). However, 
that provision includes a requirement for plans for the ``removal, if 
appropriate, of the site and structures.'' Because excess spoil fills 
are permanent, it is not appropriate to include plans for their removal 
in the application. Consequently, we propose to replace the requirement 
for plans for removal of the fills with a requirement for plans for 
their reclamation, which would consist of final site preparation and 
revegetation consistent with the approved postmining land use.
Proposed Paragraph (i): Additional Requirements for Bench Cuts or Rock-
Toe Buttresses
    Proposed paragraph (i) combines overlapping requirements in 
existing paragraph (c) and 30 CFR 816.71(d)(2) concerning application 
and design requirements for bench cuts or rock-toe buttresses. We 
propose to revise the existing requirements by replacing the term 
``keyway cuts'' with ``bench cuts.'' The term ``keyway cut'' is 
technically a cut beneath a dam that is used to extend low-permeability 
fill material to, but not into, bedrock. The term ``bench cut'' is more 
appropriate here because it refers to cuts into bedrock, not just down 
to bedrock, which is essential in the context of fill construction 
under steep-slope conditions.
Proposed Paragraph (j): Design Certification
    Proposed paragraph (j) would require that the application include a 
certification by a qualified registered professional engineer 
experienced in the design of earth and rock fills that the design of 
all fills and appurtenant structures meets the requirements of 30 CFR 
780.35. This requirement currently appears in the second sentence of 
existing 30 CFR 816.71(b)(1), which we propose to move to 30 CFR 780.35 
consistent with our effort to consolidate design requirements in the 
permitting rules rather than splitting them between the permitting 
rules and the performance standards. We propose no substantive changes 
to this provision.
17. Section 780.37: What information must I provide concerning access 
and haul roads?
    We propose to revise and reorganize existing paragraphs (a)(1), 
(2), (3), and (5) into proposed paragraphs (a)(1) and (2) to improve 
clarity and to eliminate redundancies and unnecessary cross-references. 
Proposed paragraph (a)(3) would require that the applicant demonstrate 
how all proposed roads will comply with the applicable requirements of 
30 CFR 780.28 (activities in, through, or near streams), 816.150 
(general performance standards for roads), and 816.151 (performance 
standards for primary roads). Section

[[Page 44523]]

780.28 is an element of the rule that we are proposing today, while 30 
CFR 816.150 and 816.151 are existing rules.
    We propose to add paragraph (a)(4) to require that the application 
identify each road that would be located in or within 100 feet of the 
channel of a perennial or intermittent stream,\458\ each proposed ford 
of a perennial or intermittent stream that would be used as a temporary 
route during road construction, any plans to alter or relocate a 
natural stream channel, and each proposed low-water crossing of a 
perennial or intermittent stream channel. The regulatory authority 
would need this information to determine compliance with the applicable 
requirements of proposed 30 CFR 780.28 and existing 30 CFR 816.150, and 
816.151.
---------------------------------------------------------------------------

    \458\ See the discussion of proposed 30 CFR 780.16(c) in this 
preamble for an explanation of how this distance must be measured.
---------------------------------------------------------------------------

    We also propose to add paragraph (a)(5) to require that the 
applicant explain why any proposed fords, alterations or relocations of 
natural stream channels, or low-water crossings are necessary and how 
they comply with the applicable requirements of proposed 30 CFR 780.28 
and section 515(b)(18) of the Act.\459\ Section 515(b)(18) of SMCRA 
\460\ provides that surface coal mining and reclamation operations must 
``refrain from the construction of roads or other access ways up a 
stream bed or drainage channel or in such proximity to such channel so 
as to seriously alter the normal flow of water.''

    The proposed revisions are needed to ensure that the stream 
protection requirements of proposed 30 CFR 780.28 are applied to roads, 
which can have very damaging environmental impacts on streams.

H. Part 783: Underground Mining Permit Applications--Minimum 
Requirements for Information on Environmental Resources and Conditions

    Part 783 contains the minimum requirements for information on 
environmental resources and environmental conditions when preparing 
applications for underground mining operations. It is the counterpart 
to part 779 for applications for surface mining operations. In general, 
part 783 is substantively identical to part 779, except for the 
substitution of ``underground mining activities'' for ``surface mining 
activities,'' the replacement of references to surface mining 
regulations with references to the corresponding underground mining 
regulations, and changes of a similar nature. Our proposed revisions to 
part 783 are similarly substantively identical to the corresponding 
revision that we propose in part 779. Therefore, this portion of the 
preamble discusses only those proposed revisions to part 783 that 
differ from the proposed revisions to the corresponding provisions of 
part 779. Otherwise, the rationale that we provide for the proposed 
revisions to part 779 applies with equal effect to our proposed 
revisions to part 783.
    We also call attention to our proposed revisions to the definition 
of ``adjacent area'' in 30 CFR 701.5, which clarifies the size and 
extent of the area to which certain of the information requirements of 
part 783 would apply. As revised, the definition would include all 
areas that could experience adverse impacts from either a surface coal 
mining operation or underground mining activities, including potential 
impacts from any subsidence that may occur as a result of underground 
mining activities. The existing definition is limited to areas that 
either would be adversely impacted or could reasonably be expected to 
be adversely impacted. If adopted as proposed, the revised definition 
would ensure the collection of baseline and other data from all areas 
where adverse impacts are possible, not just from those areas where 
adverse impacts are probable. In other words, our proposed definition 
of ``adjacent area'' would include, at a minimum, the entire area 
overlying the proposed underground workings plus the area within a 
reasonable angle of draw from the perimeter of those workings.
1. Section 783.24: What maps, plans, and cross-sections must I submit 
with my permit application?
    We propose to apply the requirements of 30 CFR 783.24(a)(5) to 
include the location of surface and subsurface man-made features 
within, passing through, or passing over the proposed permit and 
adjacent areas, rather than just the proposed permit area as in the 
corresponding proposed surface mining rules at 30 CFR 779.24(a)(5). The 
regulatory authority would need this information when evaluating the 
potential impacts of both the proposed underground mining operation and 
subsidence resulting from that operation on those features.
    Proposed 30 CFR 783.24(a)(11) would be the underground mining 
counterpart to proposed 30 CFR 779.24(a)(11), which, as previously 
discussed, would add a new provision requiring mapping of all wellhead 
protection zones \461\ located within one-half mile of the proposed 
permit area for surface mining operations. Proposed 30 CFR 
783.24(a)(11) would expand that requirement to include all wellhead 
protection zones located within one-half mile of either the proposed 
permit area of an underground mine or the area overlying the proposed 
underground workings. This expansion is warranted to ensure that the 
permit application review process includes consideration of the 
potential impact of underground mining activities, and subsidence 
resulting from those activities, on these important zones and the water 
supplies that they protect. However, this provision is not intended to 
prohibit underground mining operations within wellhead protection zones 
when those operations can be conducted in a manner that will not 
endanger public water supplies or when the permit applicant can 
identify suitable alternative sources of water capable of providing 
water of equivalent quantity and quality.
---------------------------------------------------------------------------

    \461\ A wellhead protection zone or area is a surface and 
subsurface land area regulated under the Safe Drinking Water Act (42 
U.S.C. 330f-300j) to prevent contamination of a well or well-field 
supplying a public water system.
---------------------------------------------------------------------------

    Proposed 30 CFR 783.24(a)(13) also would require that the map 
include the location of any discharge into or from an active, inactive, 
or abandoned underground or surface mine when the discharge is located 
within one-half mile of the area overlying the proposed underground 
workings, rather than just when the discharge is located within one-
half mile of the proposed permit area as in our proposed surface mining 
rules at 30 CFR 779.24(a)(13). The larger area is appropriate because 
the permit area for an underground mine does not include the area 
overlying the underground workings unless the mine disturbs the surface 
of those lands. However, the regulatory authority needs the discharge 
information from the expanded area to fully evaluate the potential 
impacts of the proposed underground mining operation on the hydrologic 
balance and to prepare the CHIA.
    We propose to lift the suspension of existing 30 CFR 783.25(a)(3), 
(a)(8), and (a)(9) and remove those provisions from our rules. Our 
proposed actions are consistent with PSMRL I, Round II, in which the 
court remanded those provisions, which were then located at 30 CFR 
783.25(c), (h), and (i), for further rulemaking proceedings because the 
preamble provided insufficient justification of the need for or 
usefulness of that information for

[[Page 44524]]

proposed underground mining operations.\462\ As discussed below in the 
context of 30 CFR 783.24(a)(21), (25), and (26), we are re-proposing 
those elements of the suspended rules that are relevant to underground 
mining operations and necessary or useful in the review of permit 
applications for underground mining operations.
---------------------------------------------------------------------------

    \462\ PSMRL I, Round II, 1980 U.S. Dist. LEXIS 17660 at *23-24 
(D.D.C. 1980), 19 ERC (BNA) 1477.
---------------------------------------------------------------------------

    Proposed 30 CFR 783.24(a)(21) would require that the application 
include information concerning the nature, depth, thickness, and 
commonly used names of the coal seams to be mined. Except for the names 
of the coal seams, this information currently is part of suspended 30 
CFR 783.25(a)(3). Information concerning the depth and thickness of the 
coal seam would assist the regulatory authority in reviewing the 
subsidence control plan. Chemical characteristics of the coal seam play 
an important role in determining whether acid mine drainage may be a 
problem. The name of the coal seam would allow the regulatory authority 
to compare reported data with data representative of that seam. The 
remaining information required by suspended 30 CFR 783.25(a)(3) either 
is not relevant to underground mining or is covered by the geologic 
information requirements in proposed 30 CFR 784.19(f), which 
corresponds to existing 30 CFR 784.22.
    Proposed 30 CFR 783.24(a)(23) would require that the application 
include a map and cross-sections showing the location and extent of 
known workings of active, inactive, or abandoned underground mines 
located either within the proposed permit area or within a 2,000-foot 
radius in any direction of the proposed underground workings. Existing 
30 CFR 783.25(a)(5) applies this requirement to the permit and adjacent 
areas. The additional specificity in our proposed rule would ensure 
that the application contains location information for all other 
underground mine workings that could either impact or be impacted by 
the proposed operation.
    Proposed 30 CFR 783.24(a)(25), like suspended 30 CFR 783.25(a)(8), 
would require that the application include maps identifying the 
location and extent of existing or previously surface-mined areas 
within the proposed permit area. This information is important in 
determining which postmining surface configuration and revegetation 
success standards apply, as well as evaluating eligibility for the 
remining provisions of 30 CFR 785.25.
    Proposed 30 CFR 783.24(a)(26) closely resembles suspended 30 CFR 
783.24(a)(9). It would require that the application include a map with 
the location and dimensions of existing areas of spoil, coal mine 
waste, noncoal waste disposal sites, dams, embankments, other 
impoundments, and water treatment facilities within the proposed permit 
area. Those features would affect the reclamation plan, and possibly 
the operations plan, for the mine, so they should be included on the 
permit application maps. The proposed rule differs from the suspended 
rule in that the proposed rule does not include ``waste,'' which is an 
undefined term of uncertain meaning. The proposed rule uses updated 
terminology concerning coal mine waste and, for the reasons discussed 
in the part of this preamble that explains our proposed removal of 
existing 30 CFR 780.15, it does not include air pollution control 
facilities.
    Finally, proposed 30 CFR 783.24(a)(27), which corresponds to 
existing 30 CFR 783.25(a)(10), would expand the scope of the existing 
rule to include conventional gas and oil wells within both the proposed 
permit and adjacent areas, rather than just within the proposed permit 
area. As in the proposed surface mining counterpart rule at 30 CFR 
779.24(a)(27), we also propose to require that the map include the 
extent of any directional or horizontal drilling for hydrocarbon 
extraction operations within both the proposed permit and adjacent 
areas. The permit area for an underground mine does not include the 
area overlying the underground workings or other areas where subsidence 
may occur. Therefore, the regulatory authority needs the information in 
proposed 30 CFR 783.24(a)(27) for both the proposed permit area and the 
adjacent area, not just the proposed permit area, when evaluating what 
impacts the proposed underground mining operation and any potential 
subsidence resulting from that operation may have on oil and gas 
operations.

I. Part 784: Underground Mining Permit Applications--Minimum 
Requirements for Reclamation and Operation Plans

    Part 784 contains the minimum requirements for operation and 
reclamation plans when preparing applications for underground mining 
operations. It is the counterpart to part 780 for applications for 
surface mining operations. In general, part 784 is substantively 
identical to part 780, except for the substitution of ``underground 
mining activities'' for ``surface mining activities,'' the replacement 
of references to surface mining regulations with references to the 
corresponding underground mining regulations, and changes of a similar 
nature. Our proposed revisions to part 784 are similarly substantively 
identical to the corresponding revisions that we propose in part 780. 
Therefore, this portion of the preamble discusses only those proposed 
revisions to part 784 that differ from the proposed revisions to the 
corresponding provisions of part 780. Otherwise, the rationale that we 
provide for the proposed revisions to part 780 applies with equal 
effect to our proposed revisions to part 784.
    We also call attention to our proposed revisions to the definition 
of ``adjacent area'' in 30 CFR 701.5, which could significantly affect 
the scope of some of the plans that part 784 requires. As revised, the 
definition would include all areas that could experience adverse 
impacts from either a surface coal mining operation or underground 
mining activities, including potential impacts from any subsidence that 
may occur as a result of underground mining activities. At a minimum, 
this area would include the entire area overlying proposed underground 
workings plus the area encompassed by an appropriate angle of draw from 
the perimeter of those workings. It also would include all areas with 
underground mine pools that could be affected as well as areas that 
could be affected by any mine pool that forms after closure of the 
underground mine and any areas that could be affected by landslides or 
blowouts resulting from the formation of that mine pool.
    The existing definition is limited to areas that either would be 
adversely impacted or could reasonably be expected to be adversely 
impacted. If adopted as proposed, the revised definition would require 
that the reclamation plan address all areas where adverse impacts are 
possible, not just those areas where adverse impacts are probable.
1. Section 784.11: What must I include in the general description of my 
proposed operation?
    We propose to add language in paragraph (b)(5) to clarify that the 
narrative required by paragraph (b) must address underground mine 
ventilation boreholes, fans, and access roads.
2. Section 784.13: What additional maps and plans must I include in the 
reclamation plan?
    Proposed 30 CFR 784.13(a)(4), which would combine existing 30 CFR 
784.23(b)(1) and (13), would require that the application include a map 
showing the location of all buildings, utility corridors, and other 
facilities to be used or constructed within the proposed

[[Page 44525]]

permit area, together with identification of each facility that will 
remain as a permanent feature after the completion of underground 
mining activities.
    We also propose to remove existing 30 CFR 784.23(b)(11), which 
requires a cross-section profile of the anticipated final surface 
configuration of the affected area, because this requirement duplicates 
part of proposed 30 CFR 784.12(d).
    The preamble to 30 CFR 780.13 includes a discussion of the proposed 
removal of existing 30 CFR 780.13(b)(7) concerning air pollution. There 
is no counterpart to existing 30 CFR 780.13(b)(7) in the underground 
mining regulations at 30 CFR 784.23, so the discussion of our proposed 
removal of that paragraph does not pertain to proposed 30 CFR 784.13. 
Paragraph numbering adjustments need to be made accordingly when 
applying the discussion in this preamble concerning 30 CFR 780.13 to 30 
CFR 784.13.
3. Section 784.19: What baseline information on hydrology, geology, and 
aquatic biology must I provide?
    Proposed paragraph (a) differs from its counterpart in proposed 30 
CFR 780.19(a) only in that it contains an additional requirement in 
paragraph (a)(5) that the baseline information collected be in 
sufficient detail to assist in preparing the subsidence control plan 
under 30 CFR 784.30. In the existing rules, this requirement appears in 
30 CFR 784.22(a)(4) and applies only to geologic information.
    Proposed paragraph (c) is substantively identical to its 
counterpart in proposed 30 CFR 780.19(c) with the exception that we 
propose to add paragraph (c)(3)(D) to the surface-water quantity 
description. This new paragraph would require that the description 
include seepage-run sampling determinations, if the application 
proposes to deploy a longwall panel beneath a perennial or intermittent 
stream or employ other types of full-extraction mining methods beneath 
a perennial or intermittent stream. Seepage runs are a series of in-
stream flow measurements taken to determine the discharge rate of the 
stream at various points. The measurement begins upstream of any 
probable impacts from the proposed underground mine, proceeds through 
the reach of the stream that lies above the proposed mine workings, and 
continues to a point in the stream downgradient of any probable impacts 
from the proposed mine. At each measurement point, the stream width is 
divided into segments and an average velocity is measured for each 
segment. The average velocity is determined by either a single 
measurement taken at a point located six-tenths of the distance from 
the surface of the stream to the bottom of the stream or an average of 
two measurements taken at two-tenths and eight-tenths of the distance 
from the surface of the stream to the bottom of the stream. The 
discharge rate of each stream segment then is calculated based on the 
cross-sectional area and the average velocity. The sum of the discharge 
rates for all stream segments is the total streamflow at that point.
    Subsidence resulting from longwall mining can cause a loss of part 
or all of the streamflow. Where the overburden is sufficiently thick 
(>100 to 150 meters), streamflow may be diverted into dilated fractures 
in the rocks immediately underlying the stream. This is especially true 
for sandstone units which, when fractured, tend to remain open, 
allowing significant transmission of streamflow to groundwater. 
Groundwater flow through fractures behaves in a cubic-root function in 
that doubling of the size of a fracture aperture enables the fracture 
to transmit approximately eight times the original flow.\463\ The 
dilation of fractures caused by subsidence resulting from longwall 
mining can and frequently does result in diversion of surface 
streamflow into the groundwater via these fractures. Where this 
happens, the loss may be spatially limited; i.e., once the stream 
passes beyond the impact footprint of the mine, the flow generally 
returns to the surface at a level expected at that point based on area-
normalized flow criteria (e.g., liters per minute per hectare drained).

1979. Validity of Cubic Law for Fluid Flow in a Deformable Rock 
Fracture, Water Resources Research, Vol. 16, No. 6, pp. 1016-1024.
---------------------------------------------------------------------------

    Seepage-run determinations are necessary to accurately determine 
the impacts of longwall mining on streamflow. Minor to moderate loss of 
streamflow often is not noticeable by visual observation. So, seepage 
run determinations are needed to quantify the impacts. Seepage run 
determinations also are needed to quantify streamflow should it return 
in reaches that are beyond the impact of mining.
    Proposed paragraph (e) sets forth the baseline information on the 
biological condition of streams that the application must include. The 
proposed requirements are substantively identical for both surface and 
underground mining operations, with the exception that applicants for 
underground mining operations must submit the required information for 
all perennial and intermittent streams within the adjacent area that 
might possibly be impacted by subsidence resulting from the proposed 
operation. As discussed in the preamble to our proposed definition of 
material damage to the hydrologic balance outside the permit area in 30 
CFR 701.5, the regulatory authority may not approve any proposed 
operation that is predicted to cause subsidence that would result in 
the dewatering of perennial or intermittent streams or that is 
predicted to result in other adverse impacts that would cause the 
stream to no longer be capable of supporting existing or reasonably 
foreseeable uses or that would preclude attainment of designated uses 
under section 101(a) or 303(c) of the Clean Water Act.\464\ However, 
the regulatory authority still would need the information that this 
paragraph would require for both the area overlying the proposed 
underground workings and the area within a reasonable angle of draw 
from the perimeter of those workings to determine whether the operation 
has created material damage to the hydrologic balance outside the 
permit area as a result of unanticipated subsidence. This information 
also would provide a standard for determining when any material damage 
to the stream has been corrected under 30 CFR 817.121(a).
---------------------------------------------------------------------------

    \464\ 33 U.S.C. 1251(a) and 1313(c).
---------------------------------------------------------------------------

    We propose to add paragraph (f)(1)(iv) to the requirements for 
baseline geologic information for proposed underground mining 
operations. The new paragraph would require a description of the 
composition of the base of each perennial and intermittent stream 
within the proposed permit and adjacent areas, together with a 
prediction of how that base would be affected by subsidence and how 
subsidence of the streambed would impact streamflow. This information 
would be of value in preparation of the PHC determination under 
proposed 30 CFR 784.20 and the CHIA under proposed 30 CFR 784.21 and in 
determining whether the proposed operation may result in material 
damage to the hydrologic balance outside the permit area.
    Proposed paragraph (h) establishes conditions under which the 
regulatory authority may grant an exception from the requirement to 
provide baseline information on the biological condition of streams. It 
is substantively identical to proposed 30 CFR 780.19(h)(2), except that 
it includes a provision clarifying that the exception is not available 
if the proposed operation could cause

[[Page 44526]]

subsidence resulting in changes in the base flow of perennial or 
intermittent streams or in pooling of those streams.
    Unlike proposed 30 CFR 780.19(h), proposed 30 CFR 784.19(h) does 
not include an exception for proposed operations for which the area 
from which coal is to be extracted includes only lands eligible for 
remining. The purpose of this exception for surface mining operations 
under proposed 30 CFR 780.19(h)(1) is to provide an incentive to remine 
previously mined areas by surface mining methods and then reclaim the 
redisturbed acreage with no expenditure of public funds. However, 
underground mining operations do not involve surface mining, apart from 
preparation of the face-up for the underground mine entries. Therefore, 
underground mining operations are unlikely to result in the remining 
and reclamation of previously mined areas to any significant extent. 
Thus, an exception intended to promote the remining and reclamation of 
previously mined areas would serve little purpose in rules that apply 
only to underground mining operations.
4. Section 784.20: How must I prepare the determination of the probable 
hydrologic consequences of my proposed operation (PHC determination)?
    Proposed section 784.20, which appears at 30 CFR 784.14(e) in the 
existing rules, is substantively identical to the corresponding 
proposed rule concerning surface mining at 30 CFR 780.20, with the 
exception of paragraphs (a)(3), (a)(6), and (a)(7). Proposed paragraph 
(a)(3), like the existing rule at 30 CFR 784.14(e)(3)(iv), includes 
provisions consistent with the water replacement requirements of 
section 720 of SMCRA \465\ for underground operations rather than the 
water replacement requirements of section 717(b) of SMCRA,\466\ which 
apply only to surface mines. We propose to add paragraph (a)(6) to 
require that the PHC determination include a finding on what impact 
subsidence resulting from the proposed operation may have on perennial 
and intermittent streams. This finding is critical to a determination 
of whether the proposed operation would cause material damage to the 
hydrologic balance outside the permit area, as required by 30 CFR 
773.15(e) and section 510(b)(3) of SMCRA.\467\
---------------------------------------------------------------------------

    \465\ 30 U.S.C. 1309a.
    \466\ 30 U.S.C. 1307(b).
    \467\ 30 U.S.C. 1260(b)(3).
---------------------------------------------------------------------------

    In addition, we propose to add paragraph (a)(7), which would 
require that the PHC determination include a finding on whether the 
proposed underground workings would flood after mine closure and, if 
so, a statement and explanation of the highest anticipated 
potentiometric surface of the mine pool after closure; whether, where, 
and when the mine pool is likely to result in a surface discharge; and 
the predicted quality of any discharge from the mine pool. The 
regulatory authority would use this information, in combination with 
models and calculations of void space and adjacent mine barrier 
seepage, to predict the probability of a blowout, where and when 
blowouts might occur, and the likelihood that water discharged as a 
result of the blowout will require treatment to meet water quality 
standards or any applicable effluent limitations.
    The biggest environmental threat from an underground mine is the 
formation of a post-closure point-source discharge or baseflow 
discharge that is acidic in character (and thus usually high in metal 
concentrations) or that contains high total dissolved solids, which 
result in elevated electrical conductivity in receiving streams. Either 
characteristic can substantially degrade water quality and the 
biological condition of streams. Our proposed requirement that the PHC 
determination include information and a finding on mine pools should 
enable the applicant to make a business decision as to whether revenue 
from the proposed operation would be sufficient to justify the cost of 
preventing future noncompliant discharges of a perpetual nature. It 
also would enable the regulatory authority to prepare a better CHIA and 
require the applicant to take discharge prevention measures or change 
the mining plan to avoid creating a post-closure discharge that would 
cause material damage to the hydrologic balance outside the permit area 
in violation of section 510(b)(3) of SMCRA.\468\
---------------------------------------------------------------------------

    \468\ 30 U.S.C. 1260(b)(3).
---------------------------------------------------------------------------

    Proposed paragraph (a)(7) also would require that the PHC 
determination include a statement and explanation of the predicted 
impact of the mine pool on the hydrologic balance of the proposed 
permit and adjacent areas after the mine pool reaches equilibrium, the 
potential for a mine pool blowout or other hydrologic disturbances, the 
potential for the mine pool to destabilize surface features, and the 
potential impact of roof collapses on mine pool behavior and 
equilibrium. Both the permit applicant and the regulatory authority 
need this information to determine whether any preventive or remedial 
measures are necessary to address adverse impacts related to mine 
pools.
5. Section 784.21: What requirements apply to preparation and review of 
the cumulative hydrologic impact assessment (CHIA)?
    Proposed 30 CFR 784.21 is substantively identical to the CHIA 
requirements for surface mine permits in proposed 30 CFR 780.21, with 
one exception: Our proposed CHIA requirements for a permit for an 
underground mine do not contain a counterpart to the requirement in 
proposed 30 CFR 780.21(b)(8)(iv) that the regulatory authority find 
that the proposed operation has been designed to protect the quantity 
and quality of water in any aquifer that significantly ensures the 
prevailing hydrologic balance. That provision does not apply to 
underground mines because section 516(b)(9) of SMCRA,\469\ which is the 
underground mining counterpart to section 515(b)(10),\470\ does not 
include a counterpart to section 515(b)(10)(D), which requires 
restoration of the recharge capacity of the mined area to approximate 
premining conditions. As Congress further recognized in adopting 
section 720 of SMCRA,\471\ underground mining operations will 
necessarily dewater some aquifers. In those situations, section 720

supplies protected under that section of the law.

6. Section 784.22: What information must I include in the hydrologic 
reclamation plan and what information must I provide on alternative 
water resources?
    Proposed 30 CFR 780.22(a) is substantively identical to the 
corresponding requirements for surface mine permit applications in 
proposed 30 CFR 780.22(a), with one exception: Our proposed hydrologic 
reclamation plan requirements for a permit application for an 
underground mine do not contain a counterpart to the requirement in 
proposed 30 CFR 780.22(a)(2)(ix) that the plan demonstrate how the 
operation will restore the approximate premining recharge capacity. Not 
including a counterpart to this provision in the underground mining 
rules is consistent with the difference between sections 515 and 516 of 
SMCRA,\472\ as discussed above in the preamble to proposed 30

[[Page 44527]]

CFR 784.21. Section 515(b)(10)(D) of SMCRA \473\ requires that surface 
coal mining operations restore the recharge capacity of the mined area 
to approximate premining conditions. However, this requirement does not 
appear in the corresponding provision for underground coal mining 
operations in section 516(b)(9) of SMCRA.\474\

---------------------------------------------------------------------------

    We also propose to add paragraph (b) to require that an underground 
mining permit application contain information on alternative water 
sources. The existing rules concerning underground mining permit 
applications do not include a similar provision. However, the addition 
of this requirement would enhance the ability of both the permittee and 
the regulatory authority to ensure that the water supply replacement 
requirements of 30 CFR 817.40 and section 720 of SMCRA \475\ are 
properly implemented. Proposed paragraph (b) is substantively identical 
to the corresponding proposed surface mining requirement at 30 CFR 
780.22(b), with the exception that paragraph (b)(1) of section 784.22 
reflects the different scope of water supply replacement requirements 
for underground mining operations, as specified in 30 CFR 817.40 and 
section 720 of SMCRA.\476\

7. Section 784.23: What information must I include in my plans for the 
monitoring of groundwater, surface water, and the biological condition 
of streams during and after mining?
    Proposed 30 CFR 784.23 is substantively identical to the 
corresponding monitoring plan requirements for surface mine permit 
applications in proposed 30 CFR 780.23, except as discussed below.
    Proposed 30 CFR 784.23(a)(1)(iii) does not include a requirement 
that the groundwater monitoring plan provide for monitoring wells to be 
placed in backfilled portions of the permit area. We did not include 
this requirement because surface excavations associated with 
underground mining operations typically are small in size relative to 
surface mines and do not involve ongoing backfilling and grading 
activities. Any changes in water quality detected by wells placed in 
backfilled areas would not be useful in planning changes in future 
phases of the operation, because there would be no future phases. 
Instead, we propose to require that the groundwater monitoring plan 
include at least one monitoring well to be located in the mine pool 
after mine closure. This requirement would allow both the permittee and 
the regulatory authority to monitor changes in mine pool elevation and 
to evaluate the accuracy of the PHC determination's prediction of 
whether the mine pool ultimately will rise to the level that a surface 
discharge will result. This information is important because water 
quality in mine pools is often poor,\477\ which means that any surface 
discharge would need to be treated, potentially in perpetuity.

Flooding of an Abandoned Below-drainage Pittsburgh Coal Mine, in the 
Proceedings of the Twenty-First West Virginia Surface Mine Drainage 
Task Force Symposium, Morgantown, WV, pp. 139-160.
---------------------------------------------------------------------------

    Proposed paragraphs (a)(1)(iii) and (b)(1)(iv) would require that 
upgradient and downgradient monitoring points for groundwater and 
surface water be located at a distance sufficiently close to the 
underground mine workings to detect changes as the mining operation 
progresses. The plan must include a schedule and map for moving these 
sites as the underground workings advance. Without this provision, the 
upgradient and downgradient monitoring points could be located so far 
away from the active underground workings that they would provide no 
meaningful data for purposes of analyzing impacts of current operations 
on groundwater or surface water.
    Proposed paragraph (d) establishes conditions under which the 
regulatory authority may grant an exception from the requirement to 
monitor the biological condition of streams. It is substantively 
identical to proposed 30 CFR 780.23(d)(2), except that it includes a 
provision clarifying that the exception is not available if the 
proposed operation could cause subsidence resulting in changes in the 
base flow of a perennial or an intermittent stream or in pooling of a 
perennial or an intermittent stream.
    Unlike proposed 30 CFR 780.23(d) for permit applications for 
surface mines, proposed 30 CFR 784.23(d) does not include an exception 
for proposed underground mining operations for which the area from 
which coal is to be extracted includes only lands eligible for 
remining. The purpose of this exception for surface mining operations 
under proposed 30 CFR 780.23(d)(1) is to provide an incentive to remine 
previously mined areas by surface mining methods and then reclaim the 
redisturbed acreage with no expenditure of public funds. However, 
underground mining operations do not involve surface mining, apart from 
preparation of the face-up or mine entries, which means that any 
redisturbance-and hence reclamation--of previously mined areas would be 
comparatively minimal. Therefore, an exception intended to promote the 
surface mining and reclamation of previously mined areas would serve no 
purpose in rules that apply only to underground mining operations.
8. Section 784.24: What requirements apply to the postmining land use?
    Proposed section 784.24 is substantively identical to its proposed 
surface mining counterpart in 30 CFR 780.24. Both proposed 30 CFR 
780.24 and 784.24 would include a modified version of the interpretive 
rules concerning postmining land use changes for underground mines at 
30 CFR 784.200 and 817.200(d)(1), which we propose to remove in concert 
with this rule change. Please refer to the preamble to proposed 30 CFR 
780.24(c) for a discussion of this proposed rule change.
9. Why are we proposing to remove existing 30 CFR 784.26?
    We propose to remove existing 30 CFR 784.26 because the references 
to fugitive dust and cross-references to 30 CFR 817.95 in the existing 
rule refer to provisions that we removed in 1983 in response to a court 
decision striking down our authority to regulate air pollution under 
SMCRA, except for air pollution attendant to erosion. The court held 
that ``the legislative history indicates that Congress only intended to 
regulate air pollution related to erosion'' \478\ and that ``the 
Secretary's authority to regulate [air] pollution is limited to 
activities related to erosion.'' \479\ The court remanded former 30 CFR 
816.95 and 817.95 (1979), which contained performance standards for 
fugitive dust control, for revision. However, the court did not address 
the parallel permitting requirements at 30 CFR 780.15 and 784.26.

---------------------------------------------------------------------------

    The 1983 rulemaking removed all requirements in 30 CFR 817.95 for 
fugitive dust control practices, including requirements for monitoring 
of fugitive dust to determine compliance with federal and state air 
quality standards. That rulemaking also changed the section heading of 
30 CFR 817.95 from ``Air resources protection'' to ``Stabilization of 
surface areas'' and replaced the air quality performance standards 
formerly located in 30 CFR 817.95 with soil stabilization

[[Page 44528]]

requirements that contain no mention of fugitive dust or air quality 
monitoring. See 48 FR 1160-1163 (Jan. 10, 1983).
    However, the 1983 rulemaking did not remove the parallel permitting 
requirements in 30 CFR 784.26. Instead, we stated in the preamble to 
that rulemaking that we agreed with a commenter that we also needed to 
amend the permit application rules at 30 CFR 780.15 and 784.26 for 
consistency with the revisions to 30 CFR 816.95 and 817.95, and that we 
would do so in a subsequent independent rulemaking.\480\ Adoption of 
this proposed rule would fulfill that long-delayed commitment.
---------------------------------------------------------------------------

    \480\ 48 FR 1161 (Jan. 10, 1983).
---------------------------------------------------------------------------

    With respect to air pollution attendant to erosion, proposed 30 CFR 
784.12(f) would add a permitting counterpart to the existing 
performance standard at 30 CFR 817.95(a), which provides that all 
exposed surface areas must be protected and stabilized to effectively 
control erosion and air pollution attendant to erosion. We also propose 
to add cross-references to the dust control performance standards for 
roads in 30 CFR 817.150 and 817.151.
    We also propose to redesignate existing 30 CFR 784.25, which 
contains requirements pertaining to the return of coal processing waste 
to abandoned underground mine workings, as new 30 CFR 784.26.
10. Section 784.26: What information must I provide if I plan to return 
coal processing waste to abandoned underground workings?
    We propose to redesignate existing 30 CFR 784.25 as 30 CFR 784.26. 
We propose to revise redesignated 30 CFR 784.26 by replacing the word 
``backfill'' and its variants with ``backstow'' or equivalent 
terminology to avoid any confusion with the process of backfilling open 
pits or our proposed definition of ``backfill'' in 30 CFR 701.5. 
Proposed paragraph (b)(2) would add a requirement for a description of 
all chemicals used to process the coal, the quantity of those chemicals 
remaining in the coal processing waste, and the likely impact of those 
chemicals on groundwater and any persons, aquatic life, or wildlife 
using or exposed to that groundwater. We propose to revise paragraph 
(c) to require that the backstowing plan include plans for monitoring 
the chemicals contained in the coal processing waste and a description 
of the anticipated effect on biological communities. The regulatory 
authority needs the information described above to determine whether 
the proposed backstowing operation would cause material damage to the 
hydrologic balance outside the permit area in violation of section 
510(b)(3) of SMCRA.\481\
---------------------------------------------------------------------------

    \481\ 30 U.S.C. 1260(b)(3).
---------------------------------------------------------------------------

    We propose to add paragraph (c)(6), which would require that the 
backstowing plan submitted to the regulatory authority include the 
measures to be taken to comply with the underground mine discharge 
requirements of 30 CFR 817.41, when applicable. The inclusion of this 
provision would serve as a reminder that the permitting requirements of 
30 CFR 784.26 are not the only regulations that may apply to review of 
applications of this nature.
    We also propose to revise paragraph (d) to clarify that the 
surface-water and groundwater monitoring plans for the proposed 
backstowing operation must comply with the requirements of 30 CFR 
784.23, which apply to all operations subject to part 784.
    Finally, we propose to revise paragraph (e) to specify that the 
regulatory authority may exempt pneumatic backstowing operations from 
compliance with these requirements if the applicant demonstrates, and 
the regulatory authority finds in writing, that the proposed pneumatic 
backstowing operation will not adversely impact surface water, 
groundwater, or water supplies. The corresponding existing rule at 30 
CFR 784.25(e) lacks any requirement for a demonstration by the 
applicant and it has no criteria for determining when the regulatory 
authority may grant an exception. Such an open-ended provision is not 
consistent with the environmental protection purposes and provisions of 
SMCRA. We invite comment on whether any of the requirements of 
paragraphs (a) through (d) should apply to all pneumatic backstowing 
operations, either because the regulatory authority needs that 
information to decide whether to grant an exemption or because those 
requirements are needed to ensure that the operation is conducted in an 
environmentally sound manner.
    We also invite comment on whether we should adopt similar 
requirements that would apply to backstowing of coal processing waste 
in abandoned underground mines when that activity occurs in connection 
with either a surface coal mine or a coal preparation plant regulated 
under 30 CFR 785.21.
11. Section 784.28: What additional requirements apply to proposed 
surface activities in, through, or adjacent to streams?
    Proposed 30 CFR 784.28 is substantively identical to its surface 
mining counterpart at proposed 30 CFR 780.28, except that proposed 30 
CFR 784.28 includes language clarifying that it applies to activities 
conducted on the land surface. Like existing 30 CFR 784.28, proposed 30 
CFR 784.28 would not apply to activities conducted underground or to 
surface impacts resulting from subsidence caused by underground 
workings.
12. Section 784.30: When must I prepare a subsidence control plan and 
what information must that plan include?
    We propose to redesignate existing 30 CFR 784.20 as 30 CFR 784.30. 
Proposed 30 CFR 784.30 is substantively identical to existing 30 CFR 
784.20. However, existing 30 CFR 784.20(a)(3) contains language that we 
suspended on December 22, 1999 (64 FR 71652-71653), in response to a 
court order vacating those provisions.\482\ We propose to lift the 
suspension and then remove the previously suspended language. 
Specifically, we propose to delete the language in existing 30 CFR 
784.20(a)(3) that requires a pre-subsidence survey of the condition of 
all noncommercial buildings or occupied residential dwellings and 
related structures that might be materially damaged by subsidence, or 
have their reasonably foreseeable value diminished by subsidence, 
within the area encompassed by the angle of draw. Proposed 30 CFR 
784.30(a)(3) would retain the requirement in existing 30 CFR 
784.20(a)(3) for a pre-subsidence survey of the condition of the 
quantity and quality of all drinking, domestic, and residential water 
supplies within the proposed permit area and the adjacent area.

13. Section 784.35: What information must I provide concerning the 
minimization and disposal of excess spoil?
    Proposed 30 CFR 784.35 is substantively identical to its proposed 
surface mining counterpart at 30 CFR 780.35. Existing 30 CFR 784.19, 
which is the current underground mining counterpart to 30 CFR 780.35, 
contains an ambiguous cross-reference to the requirements of 30 CFR 
780.35, ``if appropriate.'' We propose to replace this cross-reference 
with actual regulatory text and thus eliminate the ambiguity.

[[Page 44529]]

    Proposed 30 CFR 784.35 also contains revisions to provide 
consistency with the definition of coal mine waste in 30 CFR 701.5, 
which we adopted on September 26, 1983 (48 FR 44006). Among other 
things, that definition reclassified underground development waste as 
coal mine waste, which means that fills constructed of underground 
development waste must adhere to the requirements for refuse piles 
instead of the requirements applicable to excess spoil fills. At the 
same time that we adopted the definition of coal mine waste in 1983, we 
revised our performance standards at 30 CFR 817.71 through 817.74 to 
eliminate the language that combined underground development waste with 
excess spoil for purposes of performance standards for underground 
mines. Because the definition of coal mine waste includes underground 
development waste, the disposal of underground development waste is 
subject to the performance standards for refuse piles at 30 CFR 817.83 
rather than the performance standards for the disposal of excess spoil 
that applied under the pre-1983 rules.
    The design requirements for fills in existing 30 CFR 784.19 apply 
to both underground development waste and excess spoil, which means 
that those permitting requirements are inconsistent with the 1983 
changes to the corresponding performance standards. Proposed 30 CFR 
784.35 would apply only to the disposal of excess spoil, consistent 
with the 1983 changes to our definitions and performance standards 
regarding coal mine waste. For the same reason, we propose to remove 
all references to underground development waste in existing 30 CFR 
784.19 and to revise the section heading accordingly in concert with 
our proposed redesignation of existing 30 CFR 784.19 as 30 CFR 784.35. 
Under proposed 30 CFR 784.35, the permitting requirements for refuse 
piles in proposed 30 CFR 784.25, not the excess spoil requirements of 
proposed 30 CFR 784.35, would govern the disposal of underground 
development waste.
    Proposed 30 CFR 784.35 parallels proposed 30 CFR 780.35, which 
contains the permit application requirements for the disposal of excess 
spoil generated by surface mining activities. As noted above, the 
existing rule at 30 CFR 784.19 includes those requirements by cross-
reference in a somewhat ambiguous fashion. Adding specific language in 
place of the cross-reference to 30 CFR 780.35 in the existing rule 
would be consistent with the pattern established in most of our other 
rules for surface and underground mines, in which separately codified 
provisions for surface and underground mines are nearly identical 
except for cross-references and the type of operation to which they 
apply. In addition, adding specific language in place of the cross-
reference to 30 CFR 780.35 will allow the inclusion of cross-references 
to the appropriate underground mining performance standards in part 817 
rather than having to use the cross-references in 30 CFR 780.35 to the 
surface mining performance standards in part 816.
14. Why are we proposing to remove existing 30 CFR 784.200?
    Existing 30 CFR 784.200 contains only one interpretive rule, which 
addresses the use of the permit revision process for postmining land 
use changes for underground mines. We propose to include this 
interpretive rule in 30 CFR 784.24 in revised form to the extent that 
it contains unique provisions not already present in other regulations. 
Specifically, proposed 30 CFR 784.24(c) would require that any proposed 
change to a higher or better postmining land use must be processed as a 
significant permit revision. Please refer to the preamble to proposed 
30 CFR 780.24(c) for a discussion of this proposed rule change. We will 
remove 30 CFR 784.200 if we adopt proposed 30 CFR 784.24(c).

J. Part 785: Requirements for Permits for Special Categories of Mining

1. Section 785.14: What special provisions apply to proposed 
mountaintop removal mining operations?
    We propose to revise and reorganize 30 CFR 785.14 in accordance 
with plain language principles. However, we will not discuss those 
changes here because they are nonsubstantive in nature.
    With regard to substantive changes, we propose to move existing 
paragraph (b) to 30 CFR 701.5 as part of our proposed definition of 
mountaintop removal mining. In proposed paragraph (b)(1), which 
corresponds to existing paragraph (c)(1), we propose to replace ``land 
to be affected'' with ``land to be disturbed'' to be consistent with 
the definitions of ``affected area'' and ``disturbed area'' in 30 CFR 
701.5. This change also would reflect the fact that only lands to be 
disturbed by the mining operation would have a proposed postmining land 
use.
    We propose to remove existing 30 CFR 785.14(c)(3), which provides 
that the requirements of 30 CFR part 824 must be made a specific 
condition of the permit. This provision is redundant and unnecessary 
because the performance standards of 30 CFR part 824 are independently 
enforceable. Making those performance standards a specific condition of 
the permit condition adds nothing of value. Furthermore, nothing in 
SMCRA requires this permit condition. Proposed 30 CFR 785.14(b)(8), 
like existing 30 CFR 785.14(c)(2), would continue to require that the 
applicant demonstrate, and the regulatory authority find, that the 
proposed operation has been designed to comply with the requirements of 
30 CFR part 824.
    Proposed paragraph (b)(9) would replace existing 30 CFR 
824.11(a)(9), which prohibits damage to natural watercourses below the 
lowest coal seam to be mined. We propose to delete the clause limiting 
the scope of that prohibition to watercourses below the lowest coal 
seam to be mined because that clause does not appear in the underlying 
statutory provision. Instead, section 515(c)(4)(D) of SMCRA \483\ 
provides that ``no damage will be done to natural watercourses.'' 
However, SMCRA does not define either ``damage'' or ``natural 
watercourses.''
---------------------------------------------------------------------------

    \483\ 30 U.S.C. 1265(c)(4)(D).
---------------------------------------------------------------------------

    Proposed paragraph (b)(9) would specify that we will consider no 
damage to have occurred to other natural watercourses if the applicant 
demonstrates and the regulatory authority finds in writing that all the 
following conditions exist:
     The proposed operation will not increase the amount or 
concentration of parameters of concern in discharges to groundwater and 
surface water from the proposed permit area, when compared to the 
discharges that would occur if the operation were designed to adhere to 
approximate original contour restoration requirements.
     The proposed operation will not result in changes in the 
size or frequency of peak flows from the proposed permit area that 
would cause an increase in damage from flooding, when compared to the 
impacts that would occur if the operation were designed to adhere to 
approximate original contour restoration requirements.
     The total volume of flow from the proposed permit area, 
during every season of the year, will not vary in a way that would 
adversely affect any existing or reasonably foreseeable use of surface 
water or groundwater or any designated use of surface water under 
section 101(a) or 303(c) of the Clean Water Act.\484\
---------------------------------------------------------------------------

    \484\ 33 U.S.C. 1251(a) and 1313(c), respectively.

---------------------------------------------------------------------------

[[Page 44530]]

    These requirements are intended to ensure that the proposed 
operation is designed to prevent material damage to the hydrologic 
balance outside the permit area, as required by 30 CFR 773.15(e) and 
section 510(b)(3) of SMCRA,\485\ and as we propose to define that term 
in 30 CFR 701.5.
---------------------------------------------------------------------------

    \485\ 30 U.S.C. 1260(b)(3).
---------------------------------------------------------------------------

    We invite comment on whether we can or should instead adopt a rule 
that would allow the approval of mountaintop removal mining operations 
that would damage natural watercourses within the permit area if the 
applicant can demonstrate that the damage will be fully offset by 
implementation of the fish and wildlife enhancement measures proposed 
under 30 CFR 780.16.
    Under proposed paragraph (b)(10), the revegetation plan proposed 
under 30 CFR 780.12(g) for the operation would have to require that 
those portions of the proposed permit area that are forested at the 
time of application or that would revert to forest under conditions of 
natural succession be revegetated using native tree and understory 
species to the extent that this requirement is not inconsistent with 
attainment of the proposed postmining land use. Addition of this 
requirement would improve implementation of the revegetation 
requirements of section 515(b)(19) of SMCRA.\486\ It also would be 
consistent with section 515(b)(24) of SMCRA,\487\ which provides that, 
to the extent possible, surface coal mining and reclamation operations 
must minimize disturbances to and adverse impacts on fish, wildlife, 
and related environmental values and enhance those resources where 
practicable, using the best technology currently available.

    \487\ 30 U.S.C. 1265(b)(24).
---------------------------------------------------------------------------

    Proposed paragraph (b)(11) would require that the bond posted for 
the permit under part 800 of this chapter include an amount equal to 
the cost of regrading the site to its approximate original contour and 
revegetating the regraded land in the event that the approved 
postmining land use is not implemented before expiration of the 
revegetation responsibility period under Sec.  816.115. As an 
alternative to requiring posting of this bond amount at the time of 
permit issuance, we are considering adopting a rule that would prohibit 
release of any bond amount for the entire permit until the approved 
postmining land use has been implemented. We invite comment on which 
alternative would be more effective in preventing abuse of this 
exception from the AOC restoration requirements of SMCRA.
    Proposed paragraph (b)(13) would require that the permit clearly 
identify the acreage and location of mountaintop removal mining areas. 
Many permits include several types of mining, so the permittee, the 
regulatory authority, and other interested persons need this 
information to determine which portions of the permit area are subject 
to the mountaintop removal mining provisions.
    Finally, in proposed paragraph (c), we propose to replace the 
permit review requirements of existing paragraphs (d)(1) and (2) with a 
cross-reference to the permit review requirements of proposed 30 CFR 
774.10(a)(2). Existing paragraph (d)(1) requires a permit review within 
the sixth month preceding the third year from the date of permit 
issuance, before each permit renewal, and not later than the middle of 
each permit term. Proposed 30 CFR 774.10(a)(2) would replace both this 
provision and a corresponding provision in existing 30 CFR 774.10(a)(3) 
with language that is consistent with the underlying statutory 
provision in section 515(c)(6) of SMCRA,\488\ which requires that 
permits of this type be reviewed not more than 3 years from the date of 
permit issuance, unless the permittee affirmatively demonstrates that 
the proposed development is proceeding in accordance with the terms of 
the approved schedule and reclamation plan. This review is a one-time 
requirement, not a recurring event.

2. Section 785.16: What special requirements apply to proposed 
variances from approximate original contour restoration requirements 
for steep-slope mining?
Proposed Paragraph (a): Application and Approval Requirements
    We propose to revise 30 CFR 785.16(a) to clarify that a variance 
approved under this section may apply to only a portion of the permit 
area rather than to the entire permit area. This change would emphasize 
that a variance should be limited to the smallest area necessary to 
accommodate the proposed postmining land use for which the variance is 
granted.
    We propose to include the criteria in existing 30 CFR 816.133(d) 
and 817.133(d) for approval of a variance from approximate original 
contour requirements in 30 CFR 785.16 because those variances may be 
granted only for steep-slope mining operations. Consolidation of all 
steep-slope variance provisions into 30 CFR 785.16 would make our 
regulations easier to understand and more user-friendly.
    Proposed paragraph (a)(8) would allow approval of a variance only 
if the variance will not result in the construction of a fill in a 
perennial or an intermittent stream. Sacrificing perennial or 
intermittent stream segments for the purpose of creating a different 
postmining land use is neither appropriate nor warranted in view of 
paragraphs (a) and (d) of section 102 of SMCRA.\489\ Those paragraphs 
provide that two of the purposes of SMCRA are to establish a nationwide 
program to protect society and the environment from the adverse effects 
of surface coal mining operations and to assure that those operations 
are conducted in a manner that protects the environment.

    Proposed paragraph (a)(8) is consistent with section 515(b)(23) of 
SMCRA,\490\ which requires that surface coal mining and reclamation 
operations ``meet such other criteria as are necessary to achieve 
reclamation in accordance with the purposes of this Act, taking into 
consideration the physical, climatological, and other characteristics 
of the site.'' Addition of this provision also would be consistent with 
sections 515(b)(24) and 516(b)(11) of SMCRA,\491\ which require that 
surface coal mining and reclamation operations be conducted so as to 
minimize disturbances and adverse impacts on fish, wildlife, and 
related environmental values to the extent possible, using the best 
technology currently available.

    Proposed paragraph (a)(9) would revise the criteria in existing 30 
CFR 785.16(a)(3) for determining when the watershed of the proposed 
permit area and the adjacent area will be deemed improved by the 
proposed operation. The proposed revisions, which we summarize and 
discuss below, would promote environmental protection in keeping with 
the purposes of SMCRA in paragraphs (a), (d), and (f) of section 102 of 
the Act.\492\ They also would be consistent with our proposed 
definition of ``material damage to the hydrologic balance outside the 
permit area'' in 30 CFR 701.5.

    Proposed paragraph (a)(9)(i) would require a demonstration that the 
proposed operation would reduce the amount or concentration of total 
suspended solids or other parameters of concern in discharges to 
groundwater or surface water. The proposed rule corresponds to the 
first part of existing

[[Page 44531]]

30 CFR 785.16(a)(3)(i), which does not mention concentration. We 
propose to add a reference to concentration because the concentration 
of parameters of concern in discharges may be more ecologically 
important than actual amounts under certain conditions. In addition, 
the existing rule refers to pollutants rather than parameters of 
concern. We propose to replace ``pollutants'' with ``parameters of 
concern'' because the latter term potentially encompasses a broader 
range of ecologically important discharge characteristics than would 
the term ``pollutants.'' We also propose to delete the somewhat 
ambiguous language in the existing rule that refers to improvement of 
public or private uses or the ecology of the water. The language 
proposed for deletion is not necessary because the critical factor is 
whether the proposed operation would reduce the amount or concentration 
of parameters of concern.
    We propose to revise paragraph (a)(9)(ii), which corresponds to the 
last part of existing 30 CFR 785.16(a)(3)(i), by adding a reference to 
the ``size or frequency'' of peak-flow discharges. Both size and 
frequency factor into damage from floods, so the applicant and the 
regulatory authority should consider both factors.
    Proposed paragraph (a)(9)(iv) would add a requirement for a 
demonstration that the proposed operation would result in a lesser 
adverse impact on the aquatic ecology of the cumulative impact area 
than would occur if the area were to be mined and restored to its 
approximate original contour.
    Proposed paragraph (a)(9)(v) would add a requirement for a 
demonstration that the proposed operation would result in less impact 
on perennial and intermittent streams than would occur if the land were 
to be mined and restored to its approximate original contour. The 
proposed rule would allow the regulatory authority to consider fish and 
wildlife enhancement measures approved under proposed 30 CFR 780.16 and 
784.16 in making this determination. However, fish and wildlife 
enhancement measures approved under proposed 30 CFR 780.16 and 784.16 
may not be used to avoid the prohibition on excess spoil fills in 
proposed paragraph (a)(8).
    Proposed paragraphs (a)(10)(i) and (ii) contain the same surface 
owner consent provisions as existing 30 CFR 785.16(a)(4). We propose to 
add paragraph (a)(10)(iii), which would specify that the surface owner 
has not and will not receive any monetary compensation, item of value, 
or other consideration in exchange for requesting the variance. 
Proposed paragraph (a)(10)(iii) is consistent with section 102(b) of 
SMCRA,\493\ which provides that one of the purposes of the Act is to 
assure that the rights of surface landowners are fully protected from 
surface coal mining operations. It also is consistent with section 
102(a) of SMCRA,\494\ which seeks to ``protect society and the 
environment from the adverse effects of surface mining,'' by ensuring 
that variances are requested because they are necessary and appropriate 
to achieve the approved postmining land use and not due to coercion, 
deception, or monetary compensation.

    Proposed paragraph (a)(11) would require a demonstration that the 
proposed deviations from the premining surface configuration are 
necessary and appropriate to achieve the approved postmining land use. 
The intent of this provision is to ensure that variances are granted 
only for the area necessary to accommodate legitimate postmining land 
use needs.
    Proposed paragraph (a)(12) would require the use of native tree and 
understory species to revegetate all portions of the permit area that 
are forested at the time of the application or that would revert to 
forest under conditions of natural succession. This requirement would 
not apply to permanent impoundments, roads and other impervious 
surfaces to be retained following the completion of mining and 
reclamation. It also would not apply to those portions of the permit 
area covered by the variance if compliance with this requirement would 
be inconsistent with the attainment of the postmining land use. The 
intent of this provision is to encourage reforestation of reclaimed 
lands, where appropriate, and to minimize adverse impacts on fish, 
wildlife, and related environmental values, as required by sections 
515(b)(24) and 516(b)(11) of SMCRA.\495\

    Proposed paragraph (a)(13) would require that the performance bond 
posted for the permit include an amount equal to the cost of regrading 
the site to its approximate original contour and revegetating the 
regraded land in the event that the approved postmining land use is not 
implemented before expiration of the revegetation responsibility period 
under 30 CFR 816.115 or 817.115. The intent of this proposed provision 
is to ensure that variances are granted only for legitimate immediate 
postmining land use needs. If the postmining land use is not 
implemented before expiration of the revegetation responsibility 
period, the proposed rule would require that the regulatory authority 
order the permittee to restore the variance area to approximate 
original contour and plant it with the vegetation that would have been 
required had no variance been granted. The bond that this proposed 
paragraph would require would ensure that the regulatory authority has 
sufficient funds to complete the reclamation in the event that the 
permittee fails to do so.
    As an alternative to requiring posting of this bond amount at the 
time of permit issuance, we are considering adopting a rule that would 
prohibit release of any bond amount for the entire permit area until 
the postmining land use for which the variance was granted has been 
implemented. We invite comment on which alternative would be more 
effective in preventing abuse of this exception from the AOC 
restoration requirements of SMCRA.
Proposed Paragraph (b): Regulatory Authority Responsibilities
    We propose to remove existing paragraph (b)(1), which provides that 
the requirements of 30 CFR 816.133(d) or 817.133(d) must be included as 
a specific permit condition. There is no counterpart in SMCRA for this 
provision. Performance standards are just as enforceable as permit 
conditions, so there is no reason why these particular performance 
standards should be made a permit condition.
    Proposed paragraph (b)(2) would replace the permit review 
requirements of existing paragraphs (c) and (d) with a cross-reference 
to the corresponding permit review requirements of 30 CFR 774.10(a), 
which we propose to revise to be consistent with the underlying 
statutory provisions in section 515(e)(6) of SMCRA.\496\

    Proposed paragraphs (b)(3) and (4) would include existing

    Proposed paragraph (b)(5) would require that, before approving a 
steep-slope variance from approximate original contour, the regulatory 
authority find and document in writing that the surface-owner consent 
requirements of proposed paragraph (a)(10) have been met. Proposed 
paragraph (b)(5) is consistent with section 102(b) of SMCRA,\497\ which 
provides that one of the purposes of the Act is to assure that the 
rights of surface landowners are fully protected from

surface coal mining operations. It also is consistent with section 
102(a) of SMCRA,\498\ which seeks to ``protect society and the 
environment from the adverse effects of surface mining,'' by ensuring 
that variances are requested because they are necessary and appropriate 
to achieve the approved postmining land use and not due to coercion,

3. Section 785.25: What special provisions apply to proposed operations 
on lands eligible for remining?
    We propose to revise 30 CFR 785.25 to improve clarity and to 
specify that the potential environmental and safety problems that could 
reasonably be anticipated to occur must be the result of prior mining 
activities within the proposed permit area. In addition, we propose to 
specify that the identification of these anticipated problems may be 
based upon, among other things, a record review of operations near the 
site and any relevant available information, including data from prior 
mining activities and remining operations on similar sites.
    Finally, we propose to delete the term ``mitigative'' when 
referring to the measures that will be taken to ensure that reclamation 
requirements will be met. Mitigation refers to measures to be taken to 
compensate for the inability to meet reclamation requirements. Hence, 
the term is not appropriate in the context in which it is used in 
existing 30 CFR 785.25.

K. Part 800: Bond, Financial Assurance, and Liability Insurance 
Requirements for Surface Coal Mining and Reclamation Operations.

    We propose to revise part 800 by adding provisions for the use of 
financial assurances to guarantee treatment of long-term discharges, 
modifying the provisions governing alternative bonding systems, and 
adding more specific criteria and procedures to the provisions 
governing bond release. In the latter case, we propose to split 
existing 30 CFR 800.40 into five separate sections (30 CFR 800.40 
through 800.44) that address various aspects of the bond release 
process in greater detail. We also propose to adopt other changes and 
clarifications, which we discuss below on a section-by-section basis. 
In addition, for the reasons explained in Part VIII of this preamble, 
we propose to revise elements of part 800 in accordance with plain 
language principles.
1. How do we propose to guarantee treatment of long-term discharges?
    We propose to add 30 CFR 800.18 and revise other sections of part 
800 as appropriate to require that permittees post suitable financial 
instruments (known as ``financial assurances'') to guarantee that 
sufficient funds will be available for the treatment of long-term or 
perpetual discharges for which a surface or underground coal mine or 
other facility regulated under SMCRA is responsible. We also propose to 
add a definition of financial assurance in 30 CFR 800.5 and include 
necessary and appropriate references to, and provisions for, financial 
assurances in proposed 30 CFR 800.1, 800.4, 800.13, 800.15, 800.30, and 
800.42.
    Under 30 CFR 773.15(e) and section 510(b)(3) of SMCRA,\499\ the 
regulatory authority may not issue a permit unless the application 
demonstrates, and the regulatory authority finds, that the proposed 
operation has been designed to prevent material damage to the 
hydrologic balance outside the permit area. In addition, under 30 CFR 
773.15(b) and section 510(b)(2) of SMCRA,\500\ the regulatory authority 
may not issue a permit unless the application demonstrates, and the 
regulatory authority finds, that reclamation as required by the Act and 
the applicable regulatory program can be accomplished under the 
reclamation plan approved in the permit. Further, the policy entitled 
``Hydrologic Balance Protection: Policy Goals and Objectives on 
Correcting, Preventing, and Controlling Acid/Toxic Mine Drainage'' 
\501\ that we issued on March 31, 1997, states, ``[i]n no case should a 
permit be approved if the determination of probable hydrologic 
consequences or other reliable hydrologic analysis predicts the 
formation of a postmining pollutional discharge that would require 
continuing long-term treatment without a defined endpoint.'' \502\

    Improved permitting practices and advances in predictive techniques 
have almost eliminated acid mine drainage with respect to surface 
mining permits issued in the last three decades. For example, in 
Pennsylvania, a state in which acid mine drainage has historically been 
a widespread and significant problem, a 1999 study \503\ found that 
only 17 (one percent) of the 1,699 surface mining permits issued in 
Pennsylvania between1987 and1996 had long-term postmining discharges 
that required treatment. In contrast, long-term postmining discharges 
that required treatment developed on an average of 17 percent of 
permits issued between1977 and 1983 before the introduction of a 
science-based permit review program in 1984.

    However, legacy discharges from older mines remain a concern, as do 
potential discharges from underground mines after closure. Long-term 
discharges vary in quality and rate of attenuation. According to one 
study and literature review, ``surface mines and below-drainage 
underground mines improve in discharge quality relatively rapidly (20-
40 years), [but] above-drainage underground mines are not as easily 
predicted.'' \504\ The researchers examined discharges from 44 
underground mines in the Pittsburgh and Upper Freeport coal seams in 
1968 and again in 1999-2000. During the intervening 30+ years, there 
were no significant changes in pH, but iron decreased an average of 80 
percent, sulfate decreased between 50 percent and 75 percent on 
average, and total acidity decreased between 56 percent and 79 percent 
on average.\505\ While 34 of the 44 mines showed significant 
improvement in total acidity, 10 showed no change, and 3 became much 
worse.\506\ This variability supports our proposal to require that 
financial assurances for long-term discharges be calculated using a 
worst-case scenario (treatment in perpetuity) to ensure that sufficient 
funds will be available for treatment at all times. In addition, there 
are few studies evaluating the length of time treatment may be needed 
for other parameters of concern.

    Section 509(e) of SMCRA \507\ requires that the regulatory 
authority adjust the amount of bond or deposit required and the terms 
of acceptance of the bond ``where the cost of future reclamation 
changes.'' This requirement applies whenever an unanticipated discharge 
requiring long-term treatment develops. However, conventional bond 
instruments (surety bonds, collateral bonds, and self-bonds) are not 
optimal for this purpose because, under conditions of forfeiture, they 
provide a one-time lump sum payout rather than the income stream needed 
to fund

[[Page 44533]]

treatment of long-term discharges. Surety bonds and self-bonds are 
especially ill-suited for this purpose because (1) the need for 
discharge treatment may outlast the surety or the permittee and (2) 
neither a surety bond nor a self-bond requires that funds or other 
assets be physically placed with the regulatory authority or in an 
account dedicated solely to the regulatory authority, which means that 
funds would not necessarily be available to continue treatment if the 
surety and the permittee go out of business before the need for 
treatment ends. Furthermore, surety companies normally do not 
underwrite a bond when there is no expectation of release of liability, 
as would be the case with almost all long-term discharges because there 
is no reliable prospect of fully abating the source of the discharge.

    Section 509(c) of SMCRA \508\ provides that ``the Secretary may 
approve as part of a State or Federal program an alternative system 
that will achieve the objectives and purposes of the bonding program 
pursuant to this section.'' This provision affords statutory authority 
for our proposal in 30 CFR 800.18 to allow the use of financial 
assurances in place of conventional bonds when a continuing income 
stream is needed to meet ongoing treatment requirements for long-term 
discharges. Existing 30 CFR 800.11(e), which we propose to redesignate 
as 30 CFR 800.9, provides that, to meet the objectives and purposes of 
the bonding program, the alternative system (1) ``must assure that the 
regulatory authority will have available sufficient money to complete 
the reclamation plan for any areas which may be in default at any 
time;'' and (2) ``must provide a substantial economic incentive for the 
permittee to comply with all reclamation provisions.'' Establishment of 
a financial assurance in the form of a trust fund or annuity would 
satisfy the first criterion, while the permittee's provision of the 
moneys needed to establish the trust fund or annuity and the express 
terms of the trust would satisfy the second criterion.

    We relied upon this statutory authority to adopt similar financial 
assurance provisions at 30 CFR 942.800 as part of the Tennessee federal 
regulatory program.\509\ As we did in the Tennessee rulemaking, we 
propose to elaborate upon and incorporate into regulation pertinent 
elements of the policy entitled ``Hydrologic Balance Protection: Policy 
Goals and Objectives on Correcting, Preventing, and Controlling Acid/
Toxic Mine Drainage'' \510\ that we adopted on March 31, 1997. 
Specifically, Objective 2 under the ``Environmental Protection'' policy 
goal includes the following strategies:

    \510\ See www.osmre.gov/lrg/docs/amdpolicy033197.pdf (last

    Strategy 2.2--If, subsequent to permit issuance, monitoring 
identifies acid- or toxic-forming conditions which were not 
anticipated in the mining and operation plan, the regulatory 
authority should require the operator to adjust the financial 
assurance.
    Strategy 2.3--Where inspections conducted in response to bond 
release requests identify surface or subsurface water pollution, 
bond in an amount adequate to abate the pollution should be held as 
long as water treatment is required, unless a financial guarantee or 
some other enforceable contract or mechanism to ensure continued 
treatment exists.\511\

    The policy acknowledges that ``the required financial assurance may 
take a form other than those associated with a traditional performance 
bond.'' \512\ In 2002, we published an advance notice of proposed 
rulemaking entitled ``Bonding and Other Financial Assurance Mechanisms 
for Treatment of Long-Term Pollutional Discharges and Acid/Toxic Mine 
Drainage (AMD) Related Issues.'' See 67 FR 35070 (May 17, 2002). In 
that notice, we sought comments on, among other things, the form and 
amount of financial assurance that should be required to guarantee 
treatment of postmining discharges. Commenters disagreed as to whether 
financial assurance should be required, but they largely agreed that, 
if it was, surety bonds are not the best means--or even an appropriate 
means--of accomplishing that purpose because a surety bond is not 
designed to provide the income stream needed to fund ongoing treatment.
---------------------------------------------------------------------------

    \512\ Id., p. 15 (response to comment 16).
---------------------------------------------------------------------------

    We provided the following explanation of the statutory basis for 
the requirement that permittees post financial guarantees for treatment 
of long-term discharges.

    Section 509(a) of the Act requires that each permittee post a 
performance bond conditioned upon faithful performance of all the 
requirements of the Act and the permit. Paragraph (b) of this 
Section of the Act specifies that ``[t]he amount of the bond shall 
be sufficient to assure the completion of the reclamation plan if 
the work had to be performed by the regulatory authority in the 
event of forfeiture.'' The hydrologic reclamation plan is part of 
the reclamation plan to which this section refers. Section 519(c) of 
SMCRA authorizes release of this bond only when the regulatory 
authority is satisfied that the reclamation required by the bond has 
been accomplished, and paragraph (c)(3) specifies that ``no bond 
shall be fully released until all reclamation requirements of this 
Act are fully met.'' Furthermore, section 519(b) of the Act provides 
that whenever a bond release is requested, the regulatory authority 
must conduct an inspection to evaluate the reclamation work 
performed, including ``whether pollution of surface or subsurface 
water is occurring, the probability of continuance of future 
occurrence of such pollution, and the estimated cost of abating such 
pollution.'' Therefore, there is no doubt that, under SMCRA, the 
permittee must provide a financial guarantee to cover treatment of 
postmining discharges when such discharges develop and require 
treatment.\513\
---------------------------------------------------------------------------

    \513\ Id., pp. 14-15 (response to comment 16).

    The financial assurance elements of this proposed rule rely upon 
the same rationale. In addition, our financial assurance requirements 
in proposed 30 CFR 800.18 derive support from the following discussion 
in a Federal district court decision affirming our disapproval of a 
West Virginia regulatory program amendment that would have authorized 
final bond release upon installation of a passive treatment system for 
---------------------------------------------------------------------------
long-term discharges:

    SMCRA and its accompanying regulations comprise an intricate and 
complicated scheme, which contains a wealth of Congressional 
policies and purposes. See, e.g., 30 U.S.C. 1201, 1202. Further, the 
overriding policies of SMCRA, minimization of environmental damage 
and maximization of coal production, necessarily are in tension with 
each other. It is within this delicate framework that OSM regulates.
* * * * *
    The balance in the Director's approach, consistent with 
congressional direction, is readily ascertainable. The Director 
begins with the proposition that complete prevention of AMD [acid 
mine drainage] during mining and reclamation may not be possible and 
the associated environmental burden, with treatment, is judged 
tolerable resulting in a permit being issued. At this interim 
juncture, then, environmental considerations give way to the goal of 
maximizing coal production for the nation's energy requirements. 
Once an operator decides to close up shop and leave, however, it 
then would be inconsistent to allow the treatment guarantee to 
lapse, potentially saddling the taxpayers and adjoining landowners 
with a perpetual financial and environmental problem that should 
have been internalized by the operator. At this final stage, 
environmental considerations and cost internalization assume 
ultimate priority over the goal of maximization of production to 
require the total abatement of AMD.
    The Director has thus struck a reasonable balance in the face of 
Congressional ambiguity and difficult, conflicting policy 
considerations. Given satisfaction of the

interpretation.\514\

obligation of the mine operator to bear the costs associated with 
surface mining, from the permitting of a mining operation through to

    Even were treatment acceptable for bond release, the lingering 
difficulty with the proposed amendment is its hands-off approach to 
passive treatment. An operator conceivably could erect a passive 
treatment system, gain release and the system could later fail, 
leaving the taxpayers and adjoining landowners with a burden 
contrary to the policy of cost internalization. Such a burden could 
not have been intended by Congress.\516\

    \516\ Id. at 517, n. 12.

    Proposed 30 CFR 800.18 seeks to avoid precisely this burden and 
result.
    Finally, finding 1.b.(2) in the preamble to the document announcing 
our decision on another West Virginia program amendment provision 
contains the following rationale for requiring that permittees post 
performance bonds adequate to guarantee ongoing treatment of 
discharges:

    For conventional bonds, 30 CFR 800.14(b) provides that ``the 
amount of the bond shall be sufficient to assure the completion of 
the reclamation plan if the work had to be performed by the 
regulatory authority in the event of forfeiture.'' Under 30 CFR 
780.18(b)(9), 780.21(h), 784.13(b)(9), and 784.14(g), the 
reclamation plan must include the steps to be taken to comply with 
all applicable effluent limitations and State and Federal water 
quality laws and regulations. These steps include treatment. 
Therefore, when the mining and reclamation plan indicates that 
treatment will be needed on a temporary basis during mining and the 
early stages of reclamation, the bond must be calculated to include 
an amount adequate to provide for continued temporary treatment in 
the event forfeiture occurs within the timeframe during which 
treatment is needed. Also, under 30 CFR 800.15(a), the regulatory 
authority is required to adjust the amount and terms of a 
conventional bond whenever the cost of future reclamation changes. 
Therefore, if an unanticipated treatment need arises, the regulatory 
authority has an obligation to order an increase in the minimum bond 
required for the site. This amount must be adequate to cover all 
foreseeable treatment costs. This interpretation is consistent with 
the preamble to 30 CFR 800.17, which under the heading ``Section 
800.17(c)'' states that:
    ``Performance bonding continues to be required at Sec.  
800.17(a) for surface disturbances incident to underground mining to 
ensure that the reclamation plan is completed for those areas. 
Completion of the reclamation plan as it relates to mine drainage 
and protection of the hydrologic balance would continue to be 
covered by the bond with respect to requirements included in Sec.  
784.14. 48 FR 32948, July 19, 1983.''
    Sections 780.21(h) and 784.14(g) require a hydrologic 
reclamation plan showing how surface and underground mining 
operations will comply with applicable State and Federal water 
quality laws and regulations. Furthermore, section 519(b) of SMCRA 
requires the regulatory authority, when evaluating bond release 
requests, to consider whether pollution of surface and ground water 
is occurring, the probability of any continuing pollution, and the 
estimated cost of abating such pollution. Section 519(c)(3) of SMCRA 
and the implementing regulations at 30 CFR 800.40(c)(3) provide that 
no bond shall be fully released until all the reclamation 
requirements of the Act, the regulatory program, and the permit have 
been met. These requirements include abatement of surface and ground 
water pollution resulting from the operation.\517\
---------------------------------------------------------------------------

    \517\ 60 FR 51902 (Oct. 4, 1995).

    While proposed 30 CFR 800.18 focuses on financial assurance 
instruments (trust funds and annuities) to provide the necessary income 
stream, it also recognizes that collateral bonds can, under certain 
circumstances, be a satisfactory means of guaranteeing treatment of 
long-term discharges because collateral bonds require the posting of 
cash, securities, or other collateral. Specifically, proposed 30 CFR 
800.18(b)(2) would allow the use of collateral bonds provided that the 
amount of the collateral bond posted includes the cost of treating the 
discharge during the time required to collect and liquidate the bond 
and convert the proceeds to a financial instrument that will generate 
interest in an amount sufficient to cover future treatment costs and 
associated administrative expenses.
2. How do we propose to revise the definitions in 30 CFR 800.5?
    We propose to revise existing 30 CFR 800.5(b)(6), which is part of 
the definition of ``collateral bond,'' to delete the reference to 
``investment-grade rated securities having a rating of AAA, AA, or A or 
an equivalent rating issued by a nationally recognized securities 
rating service.'' According to the Department of the Treasury 
regulations at 12 CFR 16.2, a security is considered investment grade 
if it is rated in one of the top four rating categories by each 
nationally recognized statistical rating organization that has rated 
the security. Our rules include only those securities with ratings in 
the top three categories. In addition, unlike the Treasury regulations, 
we do not require that the security receive these ratings from all 
organizations that have rated the security. Therefore, we propose to 
revise 30 CFR 800.5(b)(6) to eliminate the reference to ``investment-
grade'' securities and to instead use language consistent with a 
similar provision in 30 CFR 800.23(b)(3)(i). We also propose to replace 
the term ``nationally recognized securities ratings service'' with the 
term found in the Credit Rating Agency Reform Act of 2006 (Pub. L. 109-
291) and used by the Securities and Exchange Commission: ``Nationally 
recognized statistical rating organization.'' As revised, our proposed 
rule would include securities with a rating of ``A'' or higher from 
either Moody's Investors Service or Standard and Poor's or an 
equivalent rating issued by any other nationally recognized statistical 
rating organization registered with the Securities and Exchange 
Commission.
    In existing paragraph (d), we propose to define ``financial 
assurance'' as ``a trust fund, an annuity, or a combination thereof.'' 
We invite comment on whether there are other investment vehicles that 
could provide the income stream needed to guarantee treatment of long-
term discharges and therefore should be included in this definition.
3. Section 800.9: What requirements apply to alternative bonding 
systems?
    We propose to redesignate the provisions for alternative bonding 
systems in existing 30 CFR 800.11(e) as new 30 CFR 800.9(a). Proposed 
30 CFR 800.9(b) would clarify that the alternative bonding system will 
apply in lieu of the performance bond requirements of part 800 to the 
extent specified in the regulatory program and the document in which we 
approve the alternative bonding system as part of a state or federal 
program. Proposed paragraph (b) also would specify that all alternative 
bonding systems must include provisions analogous to the bond release 
provisions of proposed 30 CFR 800.40 through 800.44 and the bond 
forfeiture provisions of 30 CFR 800.50. This provision is necessary to 
ensure that the regulatory program, including the alternative bonding 
system, remains consistent with section 519 of SMCRA,\518\ which 
governs bond release, which in turn determines when the regulatory 
authority may terminate jurisdiction over the operation in accordance 
with 30 CFR 700.11(d). Proposed 30 CFR 800.9(c) would clarify that an 
alternative bonding system may be structured to include only certain

[[Page 44535]]

phases of reclamation under proposed 30 CFR 800.42, provided that the 
other phases are covered by one of the forms of bond listed in 30 CFR 
800.12. This provision would ensure that the entire operation has bond 
coverage, as required by section 509 of SMCRA.\519\
---------------------------------------------------------------------------

    \518\ 30 U.S.C. 1269.
    \519\ 30 U.S.C. 1259.
---------------------------------------------------------------------------

    Proposed 30 CFR 800.9(d)(1) would prohibit an alternative bonding 
system from covering restoration of the ecological function of a stream 
under 30 CFR 780.28, 784.28, 816.57, and 817.57. Alternative bonding 
systems are not appropriate or reliable mechanisms to guarantee 
restoration of the ecological function of a stream, given the length of 
time that we anticipate will be required to restore that function. 
Furthermore, restoration should be the responsibility of the 
individual, company, or other mining entity that makes the decision to 
mine through a stream. Existing alternative bonding systems were not 
established with the expectation that they might have to cover the 
costs of restoring the ecological function of a stream. Exposing those 
systems to these unanticipated costs could compromise their fiscal 
integrity.
    Proposed 30 CFR 800.9(d)(2)(i) would prohibit an alternative 
bonding system from covering treatment of long-term discharges that 
come into existence after the effective date of paragraph (d), unless, 
upon discovery of the discharge, the permittee contributes an amount 
sufficient to cover all costs that the alternative bonding system will 
incur to treat the discharge in perpetuity and the alternative bonding 
system sets that money aside in a separate account dedicated solely to 
treatment of that discharge. Otherwise, consistent with proposed 30 CFR 
800.18, the permittee would be required to post a financial assurance, 
a collateral bond, or a combination thereof to cover this obligation. 
Financial assurances are preferred because they produce an income 
stream, but the permittee has the option of posting a sufficiently 
large collateral bond to cover all foreseeable treatment and 
reclamation costs.
    Self-bonds are neither appropriate nor reliable for this purpose 
because they do not require the deposit of any funds with the 
regulatory authority or under the control of the regulatory authority. 
Therefore, the regulatory authority may not be able to recover the 
necessary funds if the permittee goes out of business. In that case, 
there would be no dedicated funding set aside to ensure continued 
treatment of the discharge, which means either that treatment would 
cease, resulting in environmental damage, or that a governmental entity 
would assume treatment, meaning that the public would bear the cost of 
avoiding environmental damage.
    Under proposed 30 CFR 800.9(d)(2)(ii), long-term discharges that 
came into existence before the effective date of paragraph (d) would 
continue to be covered by any applicable state alternative bonding 
system unless the regulatory authority amends its program to 
specifically establish an earlier effective date. The proposed rule 
would require that the permittee of a site with a discharge subject to 
paragraph (d)(2)(ii) contribute to the alternative bonding system an 
amount sufficient to cover all costs that the regulatory authority 
estimates that the alternative bonding system will incur to treat the 
discharge for as long as the discharge requires active or passive 
treatment to meet Clean Water Act standards or pertinent SMCRA-related 
requirements. The proposed rule would require that the alternative 
bonding system place that amount in a separate account available only 
for treatment of the discharge for which the contribution is made. The 
proposed rule further provides that a permittee unable to make this 
contribution must post a financial assurance, a collateral bond, or a 
combination thereof to cover this obligation.
4. Section 800.11: When and how must I file a bond?
    We propose to redesignate existing 30 CFR 800.11(e) as 30 CFR 
800.9. We propose to streamline the remaining provisions of existing 30 
CFR 800.11 and improve the wording and structure to clarify their 
meaning. We also propose to add a requirement that the bond be filed in 
the amount that the regulatory authority determines necessary under 30 
CFR 800.14.
    In addition, we propose to delete a mostly obsolete provision in 
existing 30 CFR 800.11(c) specifying that an operator ``may not extend 
any underground shafts, tunnels or operations'' before the regulatory 
authority accepts the performance bond required for that area. This 
provision is inconsistent with section 509(a) of SMCRA,\520\ which 
requires a performance bond only for that area of land within the 
permit area upon which the operator will conduct surface coal mining 
and reclamation operations. Paragraphs (27) and (28) of section 701 of 
SMCRA \521\ define surface coal mining and reclamation operations, in 
relevant part, as ``activities conducted on the surface of lands'' and 
``the areas upon which such activities occur or where such activities 
disturb the natural land surface.'' Therefore, SMCRA does not require 
posting of performance bond for underground workings.
---------------------------------------------------------------------------

    \520\ 30 U.S.C. 1259(a).
    \521\ 30 U.S.C. 1291(27) and (28).
---------------------------------------------------------------------------

    Proposed paragraph (d) would replace the mostly obsolete provision 
in existing paragraph (c) with a prohibition on disturbing any surface 
area (by any type of surface coal mining operation) or extending any 
vertical underground mine shaft or other vertical underground mine 
opening for which a performance bond is required before the regulatory 
authority accepts the performance bond required for that area or 
extension. A performance bond is required for extension of vertical 
underground mine shafts and other vertical underground mine openings 
because those openings must be filled upon the completion of mining and 
the depth of the opening will affect the cost of reclamation.
5. Section 800.12: What form of bond is acceptable?
    The first sentence of existing 30 CFR 800.12 provides that the 
regulatory authority must prescribe the form of the bond. We propose to 
redesignate this sentence as paragraph (a). The remainder of existing 
30 CFR 800.12 provides that the regulatory authority may allow the 
permittee to post a surety bond, a collateral bond, a self-bond, or a 
combination of these forms of bond. We propose to redesignate this 
provision as paragraph (b) and add paragraphs (c) through (e) to 
identify exceptions and special requirements. Proposed paragraph (c) 
would clarify that an alternative bonding system approved under 
proposed 30 CFR 800.9 is not subject to 30 CFR 800.12. Proposed 
paragraph (d) reflects the fact that proposed 30 CFR 800.18 would 
require that a permittee post either a financial assurance or a 
collateral bond to guarantee treatment of a long-term discharge.
    Consistent with proposed 30 CFR 780.28(c), 784.28(c), 816.57(b), 
and 817.57(b), proposed paragraph (e) would require that the permittee 
post a surety bond, a collateral bond, or a combination thereof to 
guarantee restoration of the ecological function of a stream segment. A 
self-bond is not an appropriate mechanism to guarantee restoration of a 
stream's ecological function because of the risk that the company may 
cease to exist during the time required to accomplish that restoration. 
In addition, a self-bond does not require that the permittee file 
financial instruments or collateral with the regulatory authority, nor 
is there any third party obligated to complete the

[[Page 44536]]

reclamation or pay the amount of the bond if the permittee defaults on 
reclamation obligations.
6. Section 800.13: What is the liability period for a bond?
    Existing 30 CFR 800.13(b) allows separate bonding of isolated and 
clearly defined portions of the permit area that require extended 
liability. We propose to revise this paragraph to allow those 
provisions to apply to the bond posted to guarantee restoration of a 
stream's ecological function under proposed 30 CFR 780.28, 784.28, 
816.57, and 817.57. The proposed addition would recognize that 
restoring the premining ecological function of a stream segment is a 
lengthy process. We also propose to revise paragraph (b) to require 
that access routes to any separately bonded areas be included within 
those areas. Under the existing rule, bonding of these routes is 
discretionary on the part of the regulatory authority. However, we see 
no basis under section 509 of SMCRA to exclude any disturbed areas from 
bonding requirements unless those areas are fully reclaimed and are no 
longer used for any activity related to mining and reclamation.
    Existing paragraph (d) provides that the permittee is responsible 
under the bond for restoring the disturbed area to a condition capable 
of supporting the approved postmining land use. It further provides 
that the permittee's responsibility does not extend to actual 
implementation of the approved use. We propose to revise this paragraph 
to reflect the proposed revisions to 30 CFR 785.16(a)(13), which would 
impose alternative reclamation requirements on the permittee if the 
postmining land use forming the basis for a variance from the 
approximate original contour restoration requirements is not 
implemented by the end of the revegetation responsibility period. We 
also propose to add a provision clarifying that proposed 30 CFR 800.18 
would govern the liability period for long-term treatment of 
discharges.
7. Section 800.14: How will the regulatory authority determine the 
amount of bond required?
    We propose to revise existing 30 CFR 800.14(a) by adding the 
biological condition of perennial and intermittent streams within the 
permit area to the list of factors that the regulatory authority must 
consider in establishing bond amounts. This revision is consistent with 
our proposal to require restoration of the ecological function of 
perennial and intermittent streams under 30 CFR 780.28, 784.28, 816.57, 
and 817.57. Streams with a more pristine biological condition may be 
more difficult to restore and thus may require a higher bond amount.
    We propose to revise existing 30 CFR 800.14(b) by adding paragraph 
(b)(2) to require that the calculations used to determine the bond 
amount specifically identify the amount of bond needed to restore 
stream function. Under proposed paragraph (b)(2), the permittee then 
would have the option of either posting a separate bond for that amount 
or incorporating it into the bond posted for the entire permit or 
increment.
    We propose to redesignate existing 30 CFR 800.14(c) as paragraph 
(f) and add a new paragraph (c) to reflect the proposed revisions to 30 
CFR 785.16(a)(13), which would impose alternative reclamation 
requirements on the permittee if the postmining land use forming the 
basis for a variance from approximate original contour restoration 
requirements is not implemented by the end of the revegetation 
responsibility period. Specifically, we propose to require that the 
amount of the bond be sufficient to restore the variance area to its 
approximate original contour if the approved postmining land use is not 
implemented by the end of the applicable revegetation responsibility 
period. This proposed requirement is intended to minimize any potential 
abuse of the steep-slope variance provision.
    Proposed 30 CFR 800.14(d) would clarify that proposed 30 CFR 800.18 
would govern the amount of the financial assurance required to 
guarantee long-term treatment of discharges.
    Proposed 30 CFR 800.14(e) is substantively identical to the 
provision in existing paragraph (b) establishing that the total bond 
posted for the entire area under one permit may not be less than 
$10,000, as required by the last clause of section 509(a) of 
SMCRA.\522\

8. Section 800.15: When must the regulatory authority adjust the bond 
amount and when may I request adjustment of the bond amount?
    We propose to revise existing 30 CFR 800.15(a) to more clearly 
distinguish between bond adjustments under section 509(e) of SMCRA 
\523\ and bond releases under section 519 of SMCRA.\524\ Specifically, 
as discussed below, we propose to incorporate into regulation our 
interpretation of section 509(e) of SMCRA,\525\ which we explain in the 
preamble to the existing rules and in Directive TSR-1, ``Handbook for 
Calculation of Reclamation Bond Amounts.'' \526\ Section 509(e) of 
SMCRA provides that ``[t]he amount of the bond or deposit required and 
the terms of each acceptance of the applicant's bond shall be adjusted 
by the regulatory authority from time to time as affected land acreages 
are increased or decreased or where the cost of future reclamation 
changes.'' The preamble to existing 30 CFR 800.15(c) states that 
``reduction of bond is considered a bond adjustment if the reduction is 
based on a change in method of operation or other circumstances which 
reduces the estimated cost for the regulatory authority to reclaim.'' 
\527\ It further states that ``any reduction in bond amount for 
reclamation work performed on disturbed areas'' does not qualify as a 
bond adjustment because ``bond for disturbed areas can only be released 
or reduced through formal release procedures of Sec.  800.40.'' \528\

    \528\ Id. at 32945.
---------------------------------------------------------------------------

    Proposed 30 CFR 800.15(a) would clarify that, consistent with 
existing policy, the changes in the cost of reclamation to which 
section 509(e) of SMCRA \529\ refers are limited to decreases in the 
cost of future reclamation as a result of (1) the approval of revisions 
to the operation and reclamation plan in the permit or (2) changes in 
the unit costs of future reclamation; e.g., the cost of moving a cubic 
yard of spoil x number of feet, the cost of planting x number of trees, 
or the hourly cost to operate a specified piece of equipment. 
Situations that qualify for bond reduction through the bond adjustment 
process on this basis would include technological advances that would 
reduce the unit costs of reclamation, approved revisions to the 
operation plan (such as a decision not to remove the lowest coal seam) 
that would result in an operation of more limited extent than 
originally approved and bonded, and approved revisions to the 
reclamation plan (such as an alteration in the postmining land use) 
that would reduce reclamation costs.
---------------------------------------------------------------------------

    \529\ 30 U.S.C. 1259(e).
---------------------------------------------------------------------------

    A bond reduction under 30 CFR 800.15 on the basis of a change in 
the cost of reclamation must be justified solely upon a demonstration 
that the reclamation cost estimates that form the basis for the 
existing bond amount are no longer valid for reasons other than 
completion of elements of the reclamation process. We propose to add 
language specifying that the bond

[[Page 44537]]

adjustment provisions may not be used to reduce the amount of the 
performance bond to reflect decreases in the cost of future reclamation 
as a result of completion of activities required under the reclamation 
plan approved in the permit. Bond reduction for completed reclamation 
activities such as backfilling or topsoil replacement may be 
accomplished only in accordance with the bond release requirements and 
procedures of proposed 30 CFR 800.40 through 800.44. Any bond reduction 
requested as a result of reclamation work performed must be submitted 
and processed as an application for bond release under proposed 30 CFR 
800.40 through 800.44.
    Under proposed 30 CFR 800.15(e), the regulatory authority would 
have to require that appropriate bond or financial assurance be posted 
in accordance with proposed 30 CFR 800.18 whenever a discharge that 
will require long-term treatment is identified.
    Proposed 30 CFR 800.15(f) would prohibit reduction of the bond 
amount to reflect the failure of the permittee to restore the 
approximate original contour or when the reclamation plan was 
improperly modified to reflect the level of reclamation completed 
rather than the level of reclamation required under the regulatory 
program.
9. Section 800.16: What are the general terms and conditions of the 
bond?
    Existing 30 CFR 800.16(e) states that the bond must provide a 
mechanism for banks and sureties to give prompt notice to the 
regulatory authority and the permittee of any action filed alleging the 
insolvency or bankruptcy of the permittee, bank, or surety or alleging 
any violations that would result in suspension or revocation of the 
bank's or surety's license or charter to do business. We propose to 
revise this paragraph so that it would apply not just to banks and 
sureties, but also to any other responsible financial entity that 
issues bonds. We see no logical or legal reason to limit the scope of 
this requirement to banks and sureties.
    We also propose to move existing 30 CFR 800.16(e)(2), which sets 
forth the actions that the permittee and regulatory authority must take 
in the event of incapacity of a bank or surety, to 30 CFR 800.30(b). 
This provision is not a term or condition of the bond. Therefore, it is 
more appropriately located in 30 CFR 800.30, which is the section that 
contains requirements for replacement of bonds.
10. Why are we proposing to remove existing 30 CFR 800.17?
    Existing 30 CFR 800.17 contains bond requirements for underground 
coal mines and long-term coal-related surface facilities and 
structures. We propose to remove this section because it largely 
duplicates provisions of other sections of part 800. The only unique 
provision authorizes the posting of bond instruments with defined 
expiration dates, provided the bond is conditioned upon extension, 
replacement, or payment in full 30 days before the expiration date. The 
rule also requires that the regulatory authority initiate bond 
forfeiture proceedings if the permittee has not filed a term extension 
or a replacement bond 30 days before the expiration date.
    This provision was originally adopted under the authority of 
section 516(d) of SMCRA,\530\ which requires consideration of ``the 
distinct difference between surface and underground coal mining'' in 
developing regulations applying the bond requirements of section 509 of 
SMCRA \531\ to underground mines. Specifically, section 800.17 provides 
a limited exception to the following provision in section 509(b) of 
SMCRA: ``Liability under the bond shall be for the duration of the 
surface coal mining and reclamation operation and for a period 
coincident with [the] operator's responsibility for revegetation 
requirements in section 515.'' This exception is no longer necessary 
because underground mines can obtain letters of credit and other bonds 
just as other surface coal mining operations do.

11. Section 800.18: What special provisions apply to financial 
guarantees for treatment of long-term discharges?
    Proposed 30 CFR 800.18 would establish performance bond and 
financial assurance requirements that would apply whenever any 
discharge from a surface or underground coal mine or other facility 
regulated under SMCRA requires treatment and continues or may 
reasonably be expected to continue after the completion of mining, 
backfilling, grading, and the establishment of revegetation. Part 
IX.K.1. of this preamble explains the rationale for requiring a bond or 
financial assurance to guarantee treatment of long-term discharges and 
for the use of financial assurances in place of conventional bond 
instruments.
    We also propose to apply these requirements to situations in which 
the regulatory authority finds that a discharge requiring long-term 
treatment will develop in the future, provided that the quantity and 
quality of the future discharge can be determined with reasonable 
probability. In these situations, it would be prudent to require that 
the permittee establish a trust fund or annuity during the mining phase 
when revenues are available. If the regulatory authority does not 
require establishment of a trust fund or annuity until the discharge 
actually develops, the permittee may no longer be in business or may 
lack the resources to establish a trust fund or annuity. One example of 
an operation that would meet these criteria is an underground mine that 
creates a mine pool that will reach surface elevations and begin to 
discharge at some point after mine closure.
    Proposed paragraph (b) would specify that only financial assurances 
and collateral bonds are acceptable forms of bond to guarantee 
treatment of long-term discharges. As discussed in Part IX.K.1. of this 
preamble, surety bonds and self-bonds are not appropriate instruments 
because neither would produce the income stream needed to cover 
treatment expenses and because there is a distinct possibility that the 
discharge would outlast both the permittee and the surety. If the 
permittee elects to post a collateral bond rather than a financial 
assurance, the rule would require that the amount of the collateral 
bond include the cost of treating the discharge during the time needed 
to collect and liquidate the bond and convert the proceeds to a 
financial instrument that will generate interest in an amount 
sufficient to cover future treatment costs and associated 
administrative expenses. To minimize threats to the solvency of 
alternative bonding systems, we propose to prohibit those systems from 
covering treatment of long-term discharges unless the permittee posts 
an amount equal to the cost of treating the discharge in perpetuity and 
the alternative bonding system places that money in a separate account 
dedicated solely to treatment of that discharge. However, the proposed 
rule would grandfather in operations with discharges covered by an 
alternative bonding system on the effective date of this new provision.
    Proposed paragraph (c) would specify that the amount of financial 
assurance or collateral bond required must include the cost of treating 
the discharge to meet all applicable numerical standards or limits that 
are in effect at the time that the regulatory authority issues an order 
requiring posting of a financial assurance or bond. The numerical

[[Page 44538]]

standards or limits may be established in a SMCRA permit (the criteria 
for material damage to the hydrologic balance outside the permit area), 
in a permit or authorization issued under the Clean Water Act (an NPDES 
permit, a section 404 dredge or fill permit or authorization, or a 
section 401 water quality certification), or in regulations 
implementing the Clean Water Act.
    Proposed paragraph (d) would establish requirements for the 
financial assurance instrument itself. We based these provisions on the 
experience of the Pennsylvania and Tennessee regulatory authorities in 
establishing and managing trust funds and annuities to guarantee long-
term treatment of discharges. Proposed paragraph (d) would require that 
the trust fund or annuity be in a form approved by the regulatory 
authority and contain all terms and conditions required by the 
regulatory authority. The trust fund or annuity would have to be 
established in a manner that guarantees that sufficient moneys will be 
available when needed to pay for treatment costs in perpetuity (unless 
the permittee demonstrates, and the regulatory authority finds, based 
on scientifically proven facts, that treatment will be needed for a 
lesser time, either because the discharge will attenuate or because its 
quality will improve); periodic maintenance, renovation, and 
replacement of treatment and support facilities; final reclamation of 
the sites upon which treatment facilities are located and areas used in 
support of those facilities; and administrative costs incurred by the 
regulatory authority or trustee. Calculations of the amount required 
for the trust fund or annuity would have to be based on a conservative 
anticipated rate of return on the proposed investments that is 
consistent with long-term historical rates of return for similar 
investments. The regulatory authority would be required to specify the 
investment objectives of the trust fund or annuity to ensure that those 
objectives are consistent with production of an income stream adequate 
to meet ongoing treatment needs. The trust fund or annuity must 
irrevocably establish the regulatory authority as the beneficiary of 
the trust fund or of the proceeds from the annuity for the purpose of 
treating mine drainage or other mining-related discharges to protect 
the environment and users of surface water.
    Proposed paragraph (d)(1)(i) would allow permittees a reasonable 
time to fully fund trust funds and annuities rather than requiring a 
lump-sum deposit as would be required for collateral bonds. Under the 
proposed rule, the regulatory authority could accept an arrangement by 
which the permittee builds the amount of the trust fund or annuity over 
time, provided that the permittee continues to treat the discharge 
during that time; and the regulatory authority retains all performance 
bonds posted for the permit until the trust fund or annuity reaches a 
self-sustaining level as determined by the regulatory authority. This 
provision is needed because some permittees may require additional time 
to obtain the financing needed to establish a trust fund or annuity for 
treatment of unanticipated discharges. Insisting on immediate funding 
of the full cost of a trust fund or annuity could force the permittee 
into a default on reclamation or other obligations, which could be 
counterproductive if it results in the permittee ceasing treatment or 
if it disrupts or precludes the allocation of funds for treatment or 
other reclamation activities.
    Proposed paragraph (d)(6) would require that the trust fund or 
annuity provide that disbursement of money from the trust fund or 
annuity may be made only upon written authorization of the regulatory 
authority or according to a schedule established in the agreement 
accompanying the trust fund or annuity. We anticipate that a fully 
funded trust or annuity may include provisions for disbursements to the 
permittee as a mechanism to cover the cost of water treatment, 
especially for those permittees no longer generating income from the 
mining of coal. Disbursements from the income stream of a fully funded 
trust fund or annuity would not be considered a bond release or a bond 
forfeiture because we propose to adopt these financial assurance 
provisions as an alternative bonding system for the specific purpose of 
producing the income stream needed to pay for treatment and related 
costs.
    Proposed paragraph (d)(7) would provide that the financial 
institution or company serving as a trustee or issuing an annuity must 
be one of the following:
     A national bank chartered by the Office of the Comptroller 
of the Currency.
     An operating subsidiary of a national bank chartered by 
the Office of the Comptroller of the Currency.
     A bank or trust company chartered by the state in which 
the operation is located.
     An insurance company licensed or authorized to do business 
in the state in which the operation is located or designated by the 
pertinent regulatory body of that state as an eligible surplus lines 
insurer.
     Any other financial institution or company with trust 
powers and with offices located in the state in which the operation is 
located, provided that the institution's or company's activities are 
examined or regulated by a state or federal agency.
    This proposed restriction is intended to ensure that only 
competent, reliable, and properly capitalized and insured companies are 
eligible for selection as trustees. We invite comment on whether the 
proposed list is too inclusive or exclusive.
    Proposed paragraph (e) would allow termination of a trust fund or 
annuity only upon the demise of the trustee or the company issuing the 
annuity or as specified by the regulatory authority upon a 
determination that one of the following situations exists:
     No further treatment or other reclamation measures are 
necessary.
     A satisfactory replacement bond or financial assurance has 
been posted.
     The terms of the trust fund or annuity establish 
conditions for termination and those conditions have been met.
     The trustee's administration of the trust fund or annuity 
is unsatisfactory to the regulatory authority, in which case the 
permittee or the regulatory authority must procure a new trustee.
    We invite comment on whether there are any other situations in 
which termination should be allowed or required.
    Proposed paragraph (f) would require that the regulatory authority 
establish a schedule for reviewing the performance of the trustee, the 
adequacy of the trust fund or annuity, and the accuracy of the 
assumptions upon which the trust fund or annuity is based. We propose 
to require that these reviews occur on at least an annual basis, but we 
invite comment on whether a different review frequency would be more 
appropriate and why. The rule would require that the regulatory 
authority order the permittee to provide additional resources to the 
trust fund or annuity whenever the review or any other information 
available to the regulatory authority at any time demonstrates that the 
financial assurance is no longer adequate to meet the purpose for which 
it was established.
    Proposed paragraph (g) provides that the bond replacement 
provisions of 30 CFR 800.30(a) would govern the replacement of any 
financial assurance.
    Proposed paragraph (h) specifies that release of reclamation 
liabilities and obligations under financial assurances would be subject 
to the applicable bond release provisions of proposed 30 CFR 800.40 
through 800.44.

[[Page 44539]]

    Proposed paragraph (i) provides that the permittee may apply for, 
and the regulatory authority may approve, release of any bonds posted 
for the permit or permit increment for which the regulatory authority 
has approved a financial assurance, provided that the permittee and the 
regulatory authority comply with the bond release requirements and 
procedures in proposed Sec. Sec.  800.40 through 800.44. This provision 
would apply only if the financial assurance is in place and fully 
funded, the permit or permit increment fully meets all applicable 
reclamation requirements (with the exception of the discharge and the 
presence of associated treatment and support facilities), and the 
financial assurance will serve as the bond for reclamation of the 
portion of the permit area required for postmining water treatment 
facilities and access to those facilities. Release of all other bonds 
for the site would be appropriate under these conditions because the 
fully funded trust fund or annuity would be available to fund treatment 
and reclamation activities in the event of a permittee's bankruptcy or 
dissolution.
12. Section 800.21: What additional requirements apply to collateral 
bonds?
    We propose to revise existing 30 CFR 800.21(a)(3) to allow the 
acceptance of certificates of deposit issued by financial institutions 
other than banks. We also propose to revise existing 30 CFR 
800.21(a)(4) and (d)(4) to eliminate references to the now-defunct 
Federal Savings and Loan Insurance Corporation and references to the 
obsolete $100,000 maximum on the amount insured by the Federal Deposit 
Insurance Corporation. The proposed revisions would make this section 
consistent with the current structure and nomenclature of the financial 
industry and its regulators.
13. Section 800.23: What additional requirements apply to self-bonds?
    We propose to revise existing 30 CFR 800.23(b)(3)(i) to allow the 
use of any nationally recognized statistical rating organization 
(NRSRO) registered with the Securities and Exchange Commission in 
determining whether a corporation is eligible to self-bond. The 
existing rule allows use of only Moody's Investors Service and Standard 
and Poor's. The proposed revision is consistent with the Credit Rating 
Agency Reform Act of 2006 (Pub. L. 109-291), which facilitated the 
entry of new credit rating organizations into the market by abolishing 
the authority of the Securities and Exchange Commission (SEC) to 
designate NRSROs by no-action letters and replacing that process with a 
provision that, to be recognized as an NRSRO, a rating agency must 
register with the SEC. As stated in section 2(5) of the Credit Rating 
Agency Reform Act of 2006, ``the 2 largest credit rating agencies serve 
the vast majority of the market, and additional competition is in the 
public interest.'' Therefore, our existing rule requiring use of either 
Moody's or Standard and Poor's in determining self-bonding eligibility 
is no longer appropriate.
14. Section 800.30: When may I replace a bond or financial assurance 
instrument and when must I do so?
    We propose to revise this section by combining existing 30 CFR 
800.30(a) and (b) into paragraph (a) and by deleting an unnecessary 
sentence in existing 30 CFR 800.30(b) stating that replacement of a 
performance bond does not constitute bond release. We also propose to 
extend the applicability of this section to financial assurances under 
proposed 30 CFR 800.18, and to redesignate the mandatory bond 
replacement provisions of existing 30 CFR 800.16(e)(2) as 30 CFR 
800.30(b).
    Proposed paragraph (a) would allow the regulatory authority to 
decline to accept a proffered replacement surety bond if, in the 
judgment of the regulatory authority, the new surety does not have 
adequate reinsurance or other resources sufficient to cover the default 
of one or more mining companies for which the surety has provided bond 
coverage. This proposed provision is intended to avoid a repeat of the 
situation involving Frontier Insurance Company in the 1980s in which 
the surety could not meet its obligations.
    Proposed paragraph (b) would extend the applicability of existing 
30 CFR 800.16(e)(2) to include other responsible financial entities 
issuing bonds. The existing language in 30 CFR 800.16(e)(2) applies 
only to banks and sureties, but we see no logical reason to exclude 
other bond-issuing entities from the scope of this paragraph. We also 
propose to revise this paragraph to clarify that failure to replace a 
bond within the specified time is a violation for which the regulatory 
authority must issue a notice of violation. Operating without bond 
coverage would be a violation of the permit condition required under 30 
CFR 773.17(a).
15. Section 800.40: How do I apply for release of all or part of a 
bond?
    We propose to redesignate existing 30 CFR 800.40(a) as new section 
800.40, with two substantive revisions. First, we propose to require 
that the applicant submit a certified copy of the required newspaper 
advertisement. Addition of the certification requirement would provide 
independent documentation that the newspaper advertisement has indeed 
been published for the required 4 weeks. Second, we propose to require 
that the description of the results achieved under the approved 
reclamation plan include an analysis of the results of the monitoring 
of groundwater, surface water, and the biological condition of 
perennial and intermittent streams under 30 CFR 816.35 through 816.37 
or 817.35 through 817.37. This analysis is critical to a determination 
of whether reclamation requirements relating to protection of the 
hydrologic balance have been met.
16. Section 800.41: How will the regulatory authority process my 
application for bond release?
    We propose to redesignate existing 30 CFR 800.40(b)(1) as section 
800.41 and restructure the existing rule as paragraphs (a) and (b) of 
section 800.41. We also propose two substantive revisions. First, 
proposed paragraph (a)(1) would specify that the regulatory authority's 
clock for processing the application begins only upon submittal of a 
complete application rather than upon receipt of any application. 
Second, proposed paragraph (a)(2) would clarify that a complete 
application for bond release is one that includes all items required 
under 30 CFR 800.40. The proposed additions would benefit both the 
applicant and the regulatory authority by ensuring that an application 
is complete before the review process begins, which would have the 
additional benefit of promoting the efficient use of resources.
17. Section 800.42: What are the criteria for bond release?
    We propose to redesignate existing 30 CFR 800.40(c) as 30 CFR 
800.42, with a number of substantive revisions. Proposed paragraph (a) 
sets forth the general requirements that would have to be met before 
the regulatory authority may approve an application for bond release 
and release all or part of the bond in accordance with the other 
paragraphs of 30 CFR 800.42. Proposed paragraph (a) would apply to all 
types of bond release applications (Phase I through Phase III). In 
general, sections 509(a) and 519(b) of SMCRA \532\ provide authority 
for the proposed revisions. Section 509(a) \533\ provides, in relevant 
part, that the amount of bond in place for a surface coal mining and

[[Page 44540]]

reclamation operation ``shall be sufficient to assure the completion of 
the reclamation plan if the work had to be performed by the regulatory 
authority in the event of forfeiture.'' The new requirements in 
proposed paragraphs (a)(2) through (a)(6) are intended to ensure that 
the regulatory authority retains sufficient bond to complete the 
reclamation plan if the work has to be performed by the regulatory 
authority in the event of forfeiture. Section 519(b) of SMCRA \534\ 
provides that the regulatory authority's evaluation of a bond release 
application must ``consider, among other things, the degree of 
difficulty to complete any remaining reclamation, whether pollution of 
surface and subsurface water is occurring, the probability of 
continuance of future occurrence of such pollution, and the estimated 
cost of abating such pollution.'' Proposed paragraphs (a)(2) through 
(a)(6) are intended to ensure that the regulatory authority takes these 
factors into consideration.

    \533\ 30 U.S.C. 1259(a).
    \534\ 30 U.S.C. 1269(b).
---------------------------------------------------------------------------

    Proposed paragraph (a)(2) would not allow the regulatory authority 
to release any bond if, after an evaluation of the monitoring data for 
groundwater, surface water, and the biological condition of perennial 
and intermittent streams submitted under proposed 30 CFR 816.35 through 
816.37 or 817.35 through 817.37, it determines that adverse trends 
exist that may result in material damage to the hydrologic balance 
outside the permit area. This provision is intended to prevent 
premature release of bond that may be needed to correct potentially 
expensive damage to the hydrologic balance. This proposed requirement 
is consistent with section 515(b)(23) of SMCRA,\535\ which requires 
that surface coal mining and reclamation operations ``meet such other 
criteria as are necessary to achieve reclamation in accordance with the 
purposes of this Act, taking into consideration the physical, 
climatological, and other characteristics of the site.''
---------------------------------------------------------------------------

    \535\ 30 U.S.C. 1265(b)(23).
---------------------------------------------------------------------------

    Proposed paragraph (a)(3) would prohibit the release of any portion 
of the bond unless and until the permittee posts a financial assurance 
or collateral bond under proposed 30 CFR 800.18 if a discharge 
requiring long-term treatment exists either on the permit area or at a 
point that is hydrologically connected to the permit area. Adoption of 
this proposed paragraph would incorporate into regulation one of the 
strategies in the policy entitled ``Hydrologic Balance Protection: 
Policy Goals and Objectives on Correcting, Preventing, and Controlling 
Acid/Toxic Mine Drainage'' that we issued on March 31, 1997. 
Specifically, Strategy 2.3 of Objective 2 under the ``Environmental 
Protection'' goal provides that--

    Strategy 2.3--Where inspections conducted in response to bond 
release requests identify surface or subsurface water pollution, 
bond in an amount adequate to abate the pollution should be held as 
long as water treatment is required, unless a financial guarantee or 
some other enforceable contract or mechanism to ensure continued 
treatment exists.\536\

and Controlling Acid/Toxic Mine Drainage,'' OSMRE, March 31, 1997. 
Available at www.osmre.gov/lrg/docs/amdpolicy033197.pdf (last 
accessed August 27, 2014), p. 6.

    Proposed paragraph (a)(4) would apply whenever the permit area or 
increment includes a variance under 30 CFR 785.16 from restoration of 
the approximate original contour. In that case, the proposed rule would 
prohibit release of the portion of the bond described in proposed 30 
CFR 785.16(a)(13), in whole or in part, until the approved postmining 
land use is implemented or until the site is restored to the 
approximate original contour and revegetated in accordance with 30 CFR 
816.111 and 816.116 or 817.111 and 817.116. This provision is intended 
to prevent abuse of the steep-slope variance provision and to ensure 
that variances are requested and granted only when there is a 
reasonable likelihood of achieving the alternative postmining land use, 
as provided in the requirements for approval of higher or better land 
uses under section 515(b)(2) of SMCRA.\537\ Authority for this 
provision derives in part from section 515(e)(5) of SMCRA,\538\ which 
provides that the regulatory authority ``shall promulgate specific 
regulations to govern the granting of variances in accord with the 
provision of this subsection, and may impose such additional 
requirements as he deems to be necessary.''

---------------------------------------------------------------------------

    Proposed paragraph (a)(5) pertains to buildings and structures to 
be retained as part of the approved postmining land use. It would 
prohibit release of the bond amount described in proposed 30 CFR 
780.24(d)(2) or 784.24(d)(2) either until the structure is in use as 
part of the postmining land use or until the structure is removed and 
the site upon which it was located is reclaimed in accordance with part 
816 or part 817. This provision is intended to ensure that only 
structures with actual utility for the postmining land use are 
retained. Unused and unmaintained mine buildings can become dangerous 
attractive nuisances and a visual blight on the landscape. There would 
be no funds available to remove structures retained as part of the 
postmining land use at the time of bond release if they subsequently 
deteriorate.
    Proposed 30 CFR 800.42(a)(6) would require that the regulatory 
authority consider the results of the evaluation required under 
proposed 30 CFR 816.41(a)(3) when determining the amount of bond to 
release. Proposed 30 CFR 816.41(a)(3) requires that the evaluation 
consider, among other factors, the degree of difficulty to complete any 
remaining reclamation, whether pollution of surface and subsurface 
water is occurring, the probability of future occurrence of such 
pollution, and the estimated cost of abating such pollution. The 
factors listed in the proposed rule are identical to the factors listed 
in section 519(b) of SMCRA.\539\
---------------------------------------------------------------------------

    \539\ 30 U.S.C. 1269(b).
---------------------------------------------------------------------------

    Proposed paragraph (b) would include the criteria for Phase I bond 
release in existing 30 CFR 800.40(c)(1). We propose to revise the 
existing criteria by adding a provision clarifying that restoration of 
the form of perennial and intermittent stream segments mined through 
under 30 CFR 816.57 or 817.57 is part of the backfilling and grading 
process and therefore must be accomplished before the area is eligible 
for Phase I bond release. We also propose to add a provision stating 
that the amount of bond that the regulatory authority retains after 
Phase I release must be adequate to ensure that the regulatory 
authority will have sufficient funds for a third party to complete the 
remaining portion of the reclamation plan, including restoration of the 
ecological function of perennial and intermittent streams under 30 CFR 
816.57 or 817.57 and completion of any fish and wildlife enhancement 
measures required in the permit in accordance with 30 CFR 780.16 or 
784.16, in the event of forfeiture. The proposed additional 
requirements are necessary and appropriate to ensure compliance with 
section 509(a) of SMCRA,\540\ which provides, in relevant part, that 
the amount of bond in place for a surface coal mining and reclamation 
operation ``shall be sufficient to assure the completion of the 
reclamation plan if the work had to be performed by the regulatory 
authority in the event of forfeiture.''

    Section 519(c)(1) of SMCRA \541\ authorizes ``release of 60 per 
centum of the bond or collateral for the applicable permit area'' upon 
the completion of backfilling, grading, and drainage control. Proposed 
paragraph (b) would clarify that section 519(c)(1) of SMCRA \542\ does 
not stand alone; i.e., that release of the entire 60 percent is neither 
required nor allowed if releasing that amount of money would result in 
retention of insufficient bond to cover remaining reclamation costs, as 
required by section 509(a) of SMCRA.\543\

    \542\ 30 U.S.C. 1269(c)(1).

---------------------------------------------------------------------------

    Proposed paragraph (c) would include the criteria for Phase II bond 
release in existing 30 CFR 800.40(c)(2). Proposed paragraph (c)(1) 
would revise the existing criteria by adding a requirement that the 
regulatory authority establish standards for determining when 
revegetation has been successfully established for purposes of this 
paragraph. Establishment connotes an element of permanence. However, 
except for prime farmland, revegetation need not meet the entire suite 
of revegetation success standards under 30 CFR 816.116 or 817.116 to 
qualify for Phase II bond release. Otherwise, there would be little 
practical difference between the criteria for Phase II and Phase III 
bond release if the revegetation responsibility period must expire 
before a site is eligible for Phase II bond release. We invite comment 
on whether we should provide national standards for establishment of 
revegetation for purposes of Phase II bond release or whether this 
decision is best left to the judgment of the regulatory authority, 
based on local conditions.
    We also propose to add a provision in proposed paragraph (c)(2) 
stating that the amount of bond that the regulatory authority retains 
after Phase II release must be adequate to ensure that the regulatory 
authority will have sufficient funds for a third party to complete the 
remaining portion of the reclamation plan, including restoration of the 
ecological function of perennial and intermittent streams under 30 CFR 
816.57 or 817.57 and completion of any fish and wildlife enhancement 
measures required in the permit in accordance with 30 CFR 780.16 or 
784.16, in the event of forfeiture. The proposed additional 
requirements are necessary and appropriate to ensure compliance with 
section 509(a) of SMCRA,\544\ which provides, in relevant part, that 
the amount of bond in place for a surface coal mining and reclamation 
operation ``shall be sufficient to assure the completion of the 
reclamation plan if the work had to be performed by the regulatory 
authority in the event of forfeiture.''

more specific cross-references to the regulations pertaining to 
permanent impoundments; i.e., 30 CFR 816.49(b) and 816.56 or 817.49(b) 
and 817.56. We invite comment on the meaning of ``silt dam'' as used in 
proposed paragraph (c)(5) and in section 519(c)(2) of SMCRA.\545\

    Proposed paragraph (d) would include the criteria for Phase III 
(final) bond release in existing 30 CFR 800.40(c)(3). We propose to add 
language in proposed paragraph (d)(2) emphasizing that Phase III 
reclamation is not completed until the permittee restores the 
ecological function of perennial and intermittent streams under 30 CFR 
816.57 or 817.57 and completes any fish and wildlife enhancement 
measures required in the permit in accordance with 30 CFR 780.16 or 
784.16.
18. Section 800.43: When and how must the regulatory authority provide 
notification of its decision on a bond release application?
    Proposed 30 CFR 800.43(a) is substantively identical to existing 30 
CFR 800.40(b)(2). Proposed 30 CFR 800.43(b) and (c) are substantively 
identical to existing 30 CFR 800.40(d) and (e), respectively.
19. Section 800.44: Who may file an objection to a bond release 
application and how must the regulatory authority respond to an 
objection?
    Proposed 30 CFR 800.44 is comprised of paragraphs (a) through (c), 
which are substantively identical to existing 30 CFR 800.40(f) through 
(h), respectively.

L. Part 816: Permanent Program Performance Standards--Surface Mining 
Activities

    In this preamble, we typically discuss only those sections and 
paragraphs for which we propose substantive revisions. For the reasons 
explained in Part VIII of this preamble, we propose to revise other 
sections and paragraphs within this part in accordance with plain 
language principles, to update cross-references, and to improve 
consistency. In general, we do not discuss those proposed changes 
because no substantive change in meaning is intended.
1. Section 816.1: What does this part do?
    Existing 30 CFR 816.1 provides that part 816 sets forth the minimum 
environmental protection performance standards to be adopted and 
implemented under regulatory programs for surface mining activities. 
However, the content requirements and approval criteria for state 
regulatory programs are located at 30 CFR parts 730 through 732. 
Therefore, we propose to revise this section to simply state that it 
sets forth the environmental protection performance standards for 
surface mining activities under the Act.
2. Section 816.2: What is the objective of this part?
    Existing 30 CFR 816.2 provides that the objective of part 816 is to 
ensure that all surface mining activities are conducted in a manner 
that preserves and enhances environmental and other values in 
accordance with the Act. However, SMCRA does not require preservation 
and enhancement of all values in all cases. Instead, as stated in 
section 102(f) of the Act,\546\ one of the purposes of the Act is to 
``strike a balance between protection of the environment and 
agricultural productivity and the Nation's need for coal as an 
essential source of energy.'' Therefore, we propose to revise 30 CFR 
816.2 to state that the objective of part 816 is to ensure that surface 
mining activities are conducted in an environmentally sound manner in 
accordance with the Act.
---------------------------------------------------------------------------

    \546\ 30 U.S.C. 1202(f).
---------------------------------------------------------------------------

3. Section 816.11: What signs and markers must I post?
    The existing rules contain four requirements to mark buffer zones 
for perennial and intermittent streams--one in the stream buffer zone 
rule for surface mining operations at 30 CFR 816.57(b), one in the 
stream buffer zone rule for underground mining operations at 30 CFR 
817.57(b), one in the requirements for signs and markers for surface 
mining operations at 30 CFR 816.11(e), and one in the requirements for 
signs and markers for underground mining operations at 30 CFR 
817.11(e). We propose to consolidate those requirements into 30 CFR 
816.11(e) and 817.11(e). Proposed 30 CFR 816.11(e) would provide that 
the boundaries of any buffer to be maintained between surface mining 
activities and perennial or intermittent streams in accordance with 
proposed 30 CFR 780.28 and 816.57 must be clearly marked to avoid 
disturbance by surface mining activities.

[[Page 44542]]

4. Section 816.22: How must I handle topsoil, subsoil, and other plant 
growth media?
General Discussion of Basis for Proposed Revisions
    In general, our proposed revisions to this section would improve 
implementation of section 515(b)(6) of SMCRA,\547\ which requires that 
surface coal mining operations ``restore the topsoil or the best 
available subsoil which is best able to support vegetation,'' and 
section 515(b)(5) of SMCRA,\548\ which states that surface coal mining 
operations must--
---------------------------------------------------------------------------

    \547\ 30 U.S.C. 1265(b)(6).
    \548\ 30 U.S.C. 1265(b)(5).

remove the topsoil from the land in a separate layer, replace it on 
the backfill area, or if not utilized immediately, segregate it in a 
separate pile from other spoil and when the topsoil is not replaced 
on a backfill area within a time short enough to avoid deterioration 
of the topsoil, maintain a successful cover by quick growing plant 
or other means thereafter so that the topsoil is preserved from wind 
and water erosion, remains free of any contamination by other acid 
or toxic material, and is in a usable condition for sustaining 
vegetation when restored during reclamation, except if topsoil is of 
insufficient quantity or of poor quality for sustaining vegetation, 
or if other strata can be shown to be more suitable for vegetation 
requirements, then the operator shall remove, segregate, and 
preserve in a like manner such other strata which is best able to 
---------------------------------------------------------------------------
support vegetation.

    Existing 30 CFR 816.22 focuses primarily on topsoil handling. We 
propose to revise this section and its permitting counterpart at 30 CFR 
780.12(e) to require salvage, protection, and redistribution of soil 
materials in addition to the topsoil to ensure that the reconstructed 
soil on the reclaimed minesite provides a root zone of sufficient depth 
and comprised of appropriate soil and overburden materials that will 
create a plant growth medium suitable for the vegetation to be planted. 
The existing regulations are either unclear on this point (see existing 
paragraphs (a)(1)(ii) and (2), which sometimes have been interpreted as 
meaning that soil materials other than topsoil need be salvaged, 
stored, and redistributed only if the topsoil is less than 6 inches 
thick or is of poor quality) or, in the case of existing paragraph (e), 
make salvage of soil materials other than topsoil discretionary on the 
part of the regulatory authority.
    The revised performance standards in proposed paragraphs (a), (b), 
and (e) of 30 CFR 816.22 and the soil-handling plan required by 
proposed 30 CFR 780.12(e) would require salvage, protection, storage, 
and redistribution of whatever soil materials are necessary to ensure 
that the site will be restored ``to a condition capable of supporting 
the uses which it was capable of supporting prior to any mining, or 
higher or better uses of which there is reasonable likelihood,'' as 
required by section 515(b)(2) of SMCRA,\549\ and to ensure that the 
site will be able to meet the revegetation requirements of paragraphs 
(b)(19) and (20) of section 515 of the Act.\550\ The preamble 
discussion of proposed 30 CFR 780.12(e), to which we are proposing to 
move paragraphs (b) and (e) of existing 30 CFR 816.22 in revised form, 
provides additional background on the basis and purpose for the 
proposed revisions. In addition, Forest Reclamation Advisory No. 8 (one 
of the publications implementing and supporting the Forestry 
Reclamation Approach) states that deep soil is required for productive 
tree growth and that ``[s]alvaging and re-spreading only the upper few 
inches or horizons of soil is unlikely to restore premining capability 
unless additional materials suitable for reforestation are added.''

    Furthermore, the following excerpt from a U.S. District Court for 
the District of Columbia decision in PSMRL I, Round I concerning the 
1979 version of our regulations at 30 CFR 816.22(d), which required 
segregation of the B horizon and portions of the C horizon if the 
regulatory authority determined that those materials were necessary or 
desirable to ensure soil productivity, provides support for our 
proposed revisions:
Section 515(b)(5) [of SMCRA] authorizes segregation [of materials 
other than topsoil] if the topsoil cannot sustain vegetation or if 
other strata enhance post-mining vegetation. This is essentially 
what the regulations command. They focus on ``soil productivity,'' 
and grant the regulatory authority power to require segregation if 
necessary to improve such productivity.\552\

Proposed Paragraph (a): Removal and Salvage
    Proposed paragraph (a) would require that the permittee separately 
remove and salvage all topsoil and other soil materials identified for 
salvage and use as postmining plant growth media in the soil-handling 
plan approved in the permit under Sec.  780.12(e). The rule would 
require completion of removal and salvage of these materials from the 
area to be disturbed before any drilling, blasting, mining, or other 
surface disturbance takes place on that area. Like the existing rule, 
it provides an exemption for minor disturbances.
    The proposed rule differs from the existing rule primarily in that 
it requires removal and salvage of all topsoil and other soil and 
overburden materials needed to reconstruct a suitable postmining plant 
growth medium throughout the root zone required to support the 
vegetation to be planted after the completion of mining. The existing 
rule requires removal and salvage of only topsoil, topsoil substitutes, 
or the top 6 inches of material when the topsoil is less than 6 inches 
in depth. As discussed above, in most cases, that material would result 
in a postmining plant growth medium of insufficient depth to support 
all land uses that the land was capable of supporting before any 
mining, which would be inconsistent with section 515(b)(2) of 
SMCRA.\553\
---------------------------------------------------------------------------

    \553\ 30 U.S.C. 1265(b)(2).
---------------------------------------------------------------------------

Proposed Paragraph (b): Storage
    The stockpiling requirements and temporary distribution provisions 
of proposed paragraph (b) are substantively identical to those of 
existing paragraph (c), with the exception that we propose to add a 
requirement that any species used to establish a vegetative cover on 
stockpiles be non-invasive to avoid endangering the success of efforts 
to revegetate the site with plants native to the area.
Proposed Paragraph (c): Soil Substitutes and Supplements
    Proposed paragraph (c) provides that when the soil handling plan 
approved in the permit in accordance with Sec.  780.12(e) provides for 
the use of substitutes for or supplements to the existing topsoil or 
subsoil, the permittee must salvage, store, and redistribute the 
overburden materials selected and approved for that purpose in a manner 
consistent with paragraphs (a), (b), and (e) of section 816.22. It is 
the counterpart to existing paragraph (a)(1)(ii), but differs in that 
it applies to all soil substitutes and supplements, not just to topsoil 
substitutes and supplements. We propose to move the approval standards 
for soil substitutes and supplements from existing paragraph (b) to 30 
CFR 780.12(e) as part of our effort to consolidate permitting 
requirements in subchapter G rather than having them split between

[[Page 44543]]

the permitting requirements of subchapter G and the performance 
standards of subchapter K.
Proposed Paragraph (d): Site Preparation
    Proposed paragraph (d)(1) would require that the permittee minimize 
grading of backfilled areas to avoid compaction of the reconstructed 
root zone, as specified in the soil-handling plan approved in the 
permit in accordance with Sec.  780.12(e). The rule would allow 
compaction only to the extent necessary to ensure stability and to 
comply with water-quality standards.
    Loosely graded soil materials have less compaction, greater water 
infiltration, and less erosion than more intensely graded soil 
materials.\554\ Greater infiltration generally makes more water 
available for plant growth and less erosion may result in a reduced 
frequency for cleanouts of sedimentation ponds.\555\ As stated in one 
research report:

erosion was highest on the intensively graded plots.\556\

    Limited compaction is also more favorable to tree root growth, 
which will increase survival and growth rates and promote the 
establishment of productive forest land on reclaimed minesites.\557\
---------------------------------------------------------------------------

---------------------------------------------------------------------------

    Proposed paragraph (d)(2) would require that, if necessary, the 
permittee rip, chisel-plow, or otherwise mechanically treat backfilled 
and graded areas before topsoil redistribution to reduce potential 
slippage of redistributed material placed on slopes and to promote root 
penetration. This provision is substantively identical to existing 
paragraph (d)(2) except that we propose to specify that the treatment 
must be mechanical in nature (ripping and chisel-plowing are the two 
most common methods) because we are not aware of any other effective 
type of treatment.
Proposed Paragraph (e): Redistribution
    Proposed paragraph (e) includes soil redistribution requirements 
analogous to those of existing paragraph (d)(1). The proposed rule 
differs from the redistribution requirements in the existing rule 
primarily in that the proposed rule would apply to all salvaged soil 
and soil substitute materials, not just to topsoil and topsoil 
substitutes and supplements, as in the existing rule. In addition, the 
proposed rule not only would require minimization of compaction to the 
extent possible (a requirement that is similar to the existing rule's 
ban on excess compaction); it would require that the permittee take 
measures to alleviate any excess compaction that does occur, which 
would minimize adverse impacts on site productivity and plant growth.
    We propose to remove existing paragraph (d)(4), which requires 
application of nutrients and soil amendments to initially-redistributed 
soil material when necessary to reestablish vegetative cover. The 
revegetation component of the reclamation plan required under proposed 
30 CFR 780.12 governs the use of nutrients and soil amendments.
    Finally, proposed paragraph (e) would require use of a 
statistically-valid sampling technique to document that soil materials 
have been redistributed in the locations and to the depths required by 
the soil-handling plan approved in the permit in accordance with Sec.  
780.12(e). We encourage use of EPA's Data Quality Objectives 
model,\558\ which is a seven-step method to assist in assuring that the 
appropriate type, quantity, and quality of data are collected for 
decision-making purposes. Site-specific variability should be taken 
into account when designing a sampling program and caution is 
recommended in the selection of composite versus discrete sampling 
methods for certain soil constituents. We invite comment on whether use 
of the EPA Data Quality Objectives model or its equivalent should be 
mandatory.

---------------------------------------------------------------------------

Proposed Paragraph (f): Organic Matter
    Proposed paragraph (f) would require the salvage of organic matter 
found on the site, including duff, other organic litter, and vegetative 
materials such as tree tops, small logs, and root balls. We propose to 
prohibit the burning or burying of these materials. Instead, for the 
reasons discussed at slightly greater length in the preamble to 
proposed 30 CFR 780.12(e), proposed paragraph (f) would require that 
the permittee redistribute the salvaged materials across the regraded 
surface or incorporate them into the soil to control erosion, promote 
growth of vegetation, serve as a source of native plant seeds and 
inoculants such as mycorrhizae, speed restoration of the soil's 
ecological community and ecosystem processes, and increase the moisture 
retention capability of the soil. Proposed paragraph (f) is consistent 
with Forest Reclamation Advisory No. 8, which states that ``[w]hen soil 
is obtained from forested areas prior to mining, the salvage operation 
should take stumps, roots, and woody debris left on the site, transport 
them to the reclaimed area, and re-spread them with the soil.'' \559\ 
The rule also would allow the use of woody debris for stream 
restoration purposes and to construct fish and wildlife habitat 
enhancement features.

    Proposed paragraph (f) would enhance implementation of section

reclamation operations establish ``a diverse, effective, and permanent 
vegetative cover of the same seasonal variety native to the area of 
land to be affected and capable of self-regeneration and plant 
succession.'' It also would improve implementation of section 
515(b)(24) of SMCRA,\561\ which requires that surface coal mining and 
reclamation operations, ``to the extent possible using the best 
technology currently available, minimize disturbances and adverse 
impacts of the operation on fish, wildlife, and related environmental 
values, and achieve enhancement of such resources where practicable.''

5. Section 816.34: How must I protect the hydrologic balance?
    This new section would incorporate, reorganize, and consolidate 
paragraphs (a), (b), and (d) of existing 30 CFR 816.41. Those 
paragraphs contain general requirements for protection of the 
hydrologic balance as well as provisions specific to protection of 
groundwater and surface water.
Proposed Paragraph (a)
    Proposed paragraph (a) is primarily comprised of existing 30 CFR 
816.41(a). However, proposed paragraph (a)(3) would add a requirement 
to protect streams within the permit area, unless

[[Page 44544]]

otherwise approved in the permit in accordance with proposed 30 CFR 
780.28 and 816.57. This provision would enhance implementation of 
section 515(b)(24) of SMCRA,\562\ which requires that surface coal 
mining and reclamation operations be conducted to minimize adverse 
impacts on fish, wildlife, and related environmental values to the 
extent possible using the best technology currently available.
---------------------------------------------------------------------------

    \562\ 30 U.S.C. 1265(b)(24).
---------------------------------------------------------------------------

    In addition, proposed paragraphs (a)(4) and (5) would clarify and 
refine the scope of existing 30 CFR 816.41(a), which requires the 
``protection or replacement of water rights.'' Proposed paragraph 
(a)(4) would require that the permittee assure the protection or 
replacement of water supplies to the extent required by 30 CFR 816.40. 
Proposed paragraph (a)(5) would require that the permittee protect 
existing water rights under state law. (Water rights are determined by 
state law.) Proposed paragraphs (a)(4) and (5) better reflect the 
provisions of section 717 of SMCRA,\563\ which contains the water 
rights and water supply replacement requirements applicable to surface 
mines. With respect to water rights, section 717(a) \564\ provides that 
nothing in SMCRA ``shall be construed as affecting in any way the right 
of any person to enforce or protect, under applicable law, his interest 
in water resources affected by a surface coal mining operation.'' With 
respect to water supply replacement, section 717(b) \565\ provides 
that--

interruption proximately resulting from such surface coal mine 
---------------------------------------------------------------------------
operation.

    Proposed paragraphs (a)(8) and (10) correspond to existing 30 CFR 
816.41(b)(1) and (d)(1), respectively. We propose to revise the 
existing rules by adopting language that more closely follows the 
language of section 515(b)(10)(A) of SMCRA.\568\ Specifically, we 
propose to replace requirements in the existing rules to minimize 
acidic or toxic drainage with requirements to avoid acid or toxic mine 
drainage. In addition, we propose to add a requirement for use of the 
best technology currently available. Section 515(b)(10) of SMCRA \569\ 
uses this phrase only in paragraph (B)(i), which pertains to suspended 
solids. However, proposed paragraphs (a)(8) and (10) of this rule would 
require use of the best technology currently available to meet the 
requirements of section 515(b)(10)(A) \570\ as well. Application of 
this standard to all surface-water and groundwater protection 
activities is appropriate because section 515(b)(24) of SMCRA \571\ 
requires use of the best technology currently available to minimize 
adverse impacts on fish, wildlife, and related environmental values. 
Surface water and groundwater quality are related environmental values 
in this context.

    In proposed paragraph (a)(11), which is the counterpart to existing 
30 CFR 816.41(d)(2), we propose to add a cross-reference to the 
surface-water runoff control plan that would be required by proposed 30 
CFR 780.29.
Proposed Paragraph (b)
    Proposed paragraph (b)(1) is substantively identical to the last 
sentence in existing 30 CFR 816.41(a) except that we propose to expand 
its scope to include a requirement that the permittee use mining and 
reclamation practices that minimize adverse impacts on stream biota 
rather than relying upon water treatment to minimize those impacts. The 
existing rule applies only to water pollution and changes in flow. We 
also propose to revise the existing rule to clarify that this 
requirement is not absolute and that it applies only to the maximum 
extent practicable.
    The addition of a reference to streams and their biota recognizes 
the importance of those features to the hydrologic balance, watershed 
ecology, and environmental values related to fish and wildlife. This 
requirement also would benefit the permittee because using mining and 
reclamation practices that avoid the creation of discharges requiring 
treatment is economically advantageous, especially for selenium where 
recent settlement agreements and court orders have resulted in the 
construction of treatment plants and implementation of treatment plans 
that will cost tens of millions of dollars.
    Proposed paragraph (b)(2) is substantively identical to the last 
sentence of existing 30 CFR 816.41(d)(1).
Proposed Paragraph (c)
    Proposed paragraph (c) is substantively identical to the middle 
sentence of existing 30 CFR 816.41(a).
Proposed Paragraph (d)
    Proposed paragraph (d) would establish examination and reporting 
requirements for the surface-runoff control structures identified in 
the surface-water runoff control plan approved in the permit under 
proposed 30 CFR 780.29. Section 515(b)(10)(B)(i) of SMCRA,\572\ which 
requires that surface coal mining operations be conducted ``so as to 
prevent, to the extent possible using the best technology currently 
available, additional contributions of suspended solids to streamflow, 
or runoff outside the permit area,'' provides legal authority for 
adoption of these requirements.
---------------------------------------------------------------------------

    \572\ 30 U.S.C. 1265(b)(10)(B)(i).
---------------------------------------------------------------------------

    In general, hydraulic structures for sediment control are designed 
to retain surface runoff from the 10-year, 24-hour precipitation event 
within the permit area and then discharge the retained runoff at a rate 
that does not exacerbate downstream and off-permit impacts. In other 
words, by retaining surface runoff on the minesite, peak flow, stream 
scour, and sediment deposition in receiving streams does not increase 
beyond the level that would occur in the absence of mining. The 
structures act as ``flow equalization chambers.''
    Proposed paragraph (d)(1) would require that the permittee examine 
the entire surface-water control system promptly after the cessation of 
each precipitation event of a specified size. The size of the 
precipitation event generating the examination would differ depending 
on average annual precipitation amounts. For consistency, we propose to 
use the same average annual precipitation amounts as section 515(b)(20) 
of SMCRA \573\ uses to determine the length of revegetation 
responsibility periods; i.e., our proposed examination requirements 
would differ depending on whether the permit lies in an area with 
average annual precipitation of 26.0 inches or less.
---------------------------------------------------------------------------

    \573\ 30 U.S.C. 1265(b)(20).
---------------------------------------------------------------------------

    Bankfull flow in a stream in an area with an average annual 
precipitation of more than 26.0 inches generally occurs in response to 
a precipitation event with a recurrence interval between 1.5 and 2 
years. Bankfull flow is the stage at which water in the stream just 
fills the stream channel to the top of its banks;

[[Page 44545]]

i.e., it is the point at which any further increase in the elevation of 
streamflow would cause water to begin to flow onto the flood plain. 
Under natural conditions, any precipitation event greater than the 2-
year event would be expected to result in some flooding--and possibly 
flood-related damage. However, the more modest flows from smaller, more 
frequent events often transport the greatest quantity of sediment 
material over time.\574\

Hydrology (1996).
---------------------------------------------------------------------------

    Hydraulic structures for surface coal mining and reclamation 
operations are typically designed with a combination of sediment and 
stormwater runoff storage capacity well in excess of the estimated 
surface runoff from the 2-year event. Failure to maintain these 
structures by removing accumulated sediment can result in a reduction 
of stormwater storage capacity, which in turn may result in a discharge 
that causes property damage or material damage to the hydrologic 
balance outside the permit area.
    Therefore, for areas with an average annual precipitation of more 
than 26.0 inches, proposed paragraph (d)(1)(i) would apply the 
examination and reporting requirements to all precipitation events that 
equal or exceed the 2-year recurrence interval. We invite comment on 
whether a precipitation event with a 2-year recurrence interval is an 
appropriate threshold for requiring examination of sediment control 
systems in mesic regions or whether we should allow variations based 
upon differences in terrain, storm frequency, the nature of 
sedimentation control structures, and the frequency with which 
discharges from sedimentation control structures occur.
    In contrast, our experience indicates that discharges from 
sedimentation ponds are extremely rare in areas with an average annual 
precipitation of 26.0 inches or less. A review of representative mines 
in the West determined that approximately one percent of all 
impoundments discharge in any single year. Another survey indicated 
that discharges occurred in only one of the past 10 years. Therefore, 
for areas with an average annual precipitation of 26.0 inches or less, 
proposed paragraph (d)(1)(ii) would apply the examination and reporting 
requirements only to significant precipitation events. The regulatory 
authority would be responsible for establishing that threshold, either 
as part of the regulatory program or in the permit. We invite comment 
on whether we should establish more specific criteria for examination 
of hydraulic structures in arid and semiarid regions.
    Proposed paragraph (d)(2) would require that the permittee prepare 
a report after the occurrence of each precipitation event that equals 
or exceeds the applicable threshold. The proposed rule would require 
that the report discuss the performance of the hydraulic structures, 
identify and describe any material damage to the hydrologic balance 
outside the permit area that occurred, and identify and describe the 
remedial measures taken in response to that damage. The proposed rule 
also would require that the report be certified by a registered 
professional engineer and be submitted to the regulatory authority 
within 48 hours of cessation of the applicable precipitation event to 
ensure that the regulatory authority has the ability to take prompt 
action to correct any deficiencies.
6. Section 816.35: How must I monitor groundwater?
    Proposed 30 CFR 816.35 is substantively identical to existing 30 
CFR 816.41(c), except as discussed below.
Proposed Paragraph (a)
    Proposed paragraph (a)(1)(i) is substantively identical to the 
first sentence of existing 30 CFR 816.41(c)(1). Proposed paragraph 
(a)(1)(ii) would require adherence to the data collection, analysis, 
and reporting requirements of proposed 30 CFR 777.13(a) and (b) when 
conducting groundwater monitoring. This provision would be consistent 
with section 517(b)(2) of SMCRA, which requires that monitoring data 
collection and analysis ``be conducted according to standards and 
procedures set forth by the regulatory authority in order to assure 
their reliability and validity.''
    Proposed paragraph (a)(2) includes the requirement in existing 30 
CFR 816.41(c)(3) that groundwater monitoring proceed through mining and 
continue during reclamation until bond release. However, we propose to 
revise the existing language to clarify that monitoring must continue 
until the entire bond amount for the monitored area has been fully 
released under proposed 30 CFR 800.42(d), not just partial or Phase I 
or II bond release. This change is appropriate because the time 
required to achieve saturation of backfilled areas or underground mine 
voids typically is measured in years, which means that mining-related 
impacts on groundwater outside the permit area may not occur until 
years after completion of mining and land reclamation. Even after 
complete saturation, groundwater migration rates typically are measured 
in only feet per day.
    Therefore, proposed paragraph (a)(2) would require that groundwater 
monitoring continue through mining and during reclamation until the 
entire bond amount for the monitored area has been fully released under 
proposed 30 CFR 800.42(d), which generally will not occur until 
expiration of the revegetation responsibility period. In addition, 
proposed 30 CFR 800.42(a) would provide that the regulatory authority 
may not release any portion of the bond if an evaluation of monitoring 
data indicates that adverse trends exist that could result in material 
damage to the hydrologic balance outside the permit area. Any shorter 
time could result in a failure to detect impacts, given the combination 
of slow saturation and migration rates.
Proposed Paragraphs (b) and (c)
    Proposed paragraphs (b) and (c) are substantively identical to 
existing 30 CFR 816.41(c)(2).
Proposed Paragraph (d)
    Proposed paragraph (d) is the counterpart to those elements of 
existing 30 CFR 816.41(c)(3) that pertain to modification of the 
groundwater monitoring plan. We propose to remove existing 30 CFR 
816.41(c)(3)(ii) because it provides that the regulatory authority may 
approve a permit revision that would allow the cessation of groundwater 
monitoring based on a finding that monitoring is no longer necessary to 
achieve the purposes of the monitoring plan. As discussed in the 
preamble to proposed paragraph (a) above, cessation of monitoring 
before the entire bond amount for the monitored area has been fully 
released under proposed 30 CFR 800.42(d) is inappropriate, based on the 
time required for saturation of the backfill and slow groundwater 
migration rates. Proposed paragraph (d) would continue to allow the 
regulatory authority to approve a permit revision to otherwise modify 
the parameters monitored and the sampling frequency under certain 
conditions. We invite comment on whether we should establish a minimum 
sampling frequency or place other restrictions on the regulatory 
authority's ability to modify monitoring requirements.
    However, to supplement the demonstrations required by existing 30 
CFR 816.41(c)(3)(i) before the regulatory authority may approve a 
permit revision of this nature, we propose to add requirements that the 
permittee demonstrate that future changes in

[[Page 44546]]

groundwater quantity or quality are unlikely and that the operation has 
preserved or restored the biological condition of perennial and 
intermittent streams with base flows originating in whole or in part 
from groundwater within the permit or adjacent areas. See proposed 
paragraphs (d)(1) and (2)(iii). The additional criteria are intended to 
ensure that groundwater monitoring requirements are not reduced or 
modified prematurely.
    In addition, we propose to replace the requirement in existing 30 
CFR 816.41(c)(3)(i) for a demonstration that the water quantity and 
quality are suitable to support approved postmining land uses with a 
requirement for a demonstration that the operation has maintained the 
availability and quality of groundwater in a manner that can support 
existing and reasonably foreseeable uses. Our proposed replacement 
language parallels the terminology in our proposed definition of 
``material damage to the hydrologic balance outside the permit area'' 
in 30 CFR 701.5.
Proposed Paragraph (e)
    Proposed paragraph (e) corresponds to the second sentence of 
existing 30 CFR 816.41(c)(1), which provides that the regulatory 
authority may require additional monitoring when necessary. We propose 
to modify the existing language to specify that the regulatory 
authority must require additional monitoring when information available 
to the regulatory authority indicates that additional monitoring is 
necessary to protect the hydrologic balance, detect hydrologic changes, 
or meet other requirements of the regulatory program. We also propose 
to specify that the regulatory authority must issue a permit revision 
order under Sec.  774.10(b) when requiring changes to the monitoring 
plan approved in the permit.
Proposed Paragraph (f)
    Like existing 30 CFR 816.41(c)(4), proposed paragraph (f) would 
require that the permittee install, maintain, operate, and, when no 
longer needed, remove all equipment, structures, and other devices used 
in conjunction with monitoring groundwater. We propose to add cross-
references to 30 CFR 816.13 and 816.39, which also contain requirements 
pertinent to the closure or disposition of monitoring wells.
7. Section 816.36: How must I monitor surface water?
    Proposed 30 CFR 816.36 is substantively identical to existing 30 
CFR 816.41(e), except as discussed below.
Proposed Paragraph (a)
    Proposed paragraph (a)(1)(I) is substantively identical to the 
first sentence of existing 30 CFR 816.41(e)(1). Proposed paragraph 
(a)(1)(ii) would require adherence to the data collection, analysis, 
and reporting requirements of proposed 30 CFR 777.13(a) and (b) when 
conducting groundwater monitoring. This provision would be consistent 
with section 517(b)(2) of SMCRA, which requires that monitoring data 
collection and analysis ``be conducted according to standards and 
procedures set forth by the regulatory authority in order to assure 
their reliability and validity.''
    Proposed paragraph (a)(2) includes the requirement in existing 30 
CFR 816.41(e)(3) that surface-water monitoring proceed through mining 
and continue during reclamation until bond release. However, we propose 
to revise the existing language to remove any ambiguity concerning the 
meaning of ``bond release'' and clarify that monitoring must continue 
until the entire bond amount posted for the monitored area has been 
fully released under proposed 30 CFR 800.42(d), not just partial or 
Phase I or II bond release. As discussed above in the portion of the 
preamble concerning proposed 30 CFR 816.35(a), this change is 
appropriate because the time required to achieve saturation of 
backfilled areas or underground mine voids typically is measured in 
years, which means that mining-related impacts on groundwater, and 
hence surface water fed by groundwater, outside the permit area may not 
occur until years after the completion of mining and land reclamation. 
Even after complete saturation, groundwater migration rates typically 
are measured in only feet per day.
    Therefore, proposed paragraph (a)(2) would require that surface-
water monitoring continue through mining and during reclamation until 
the entire bond amount posted for the monitored area has been fully 
released under proposed 30 CFR 800.42(d), which generally will not 
occur until expiration of the revegetation responsibility period. In 
addition, proposed 30 CFR 800.42(a) would provide that the regulatory 
authority may not release any portion of the bond if an evaluation of 
monitoring data indicates that adverse trends exist that could result 
in material damage to the hydrologic balance outside the permit area. 
Any shorter time could result in a failure to detect impacts on surface 
water fed by groundwater, given the combination of slow saturation and 
migration rates for groundwater.
Proposed Paragraphs (b) and (c)
    Proposed paragraphs (b) and (c) are substantively identical to 
existing 30 CFR 816.41(e)(2).
Proposed Paragraph (d)
    Proposed paragraph (d) would be the counterpart to those elements 
of existing 30 CFR 816.41(e)(3) that pertain to modification of the 
surface-water monitoring plan. We propose to remove existing 30 CFR 
816.41(e)(3)(ii) because it provides that the regulatory authority may 
approve a permit revision that would allow the cessation of surface-
water monitoring based on a finding that monitoring is no longer 
necessary to achieve the purposes of the monitoring plan. As discussed 
in the preamble to paragraph (a) above, cessation of monitoring before 
the entire bond amount for the monitored area has been fully released 
under proposed 30 CFR 800.42(d) is inappropriate, based on the time 
required for saturation of the backfill and slow groundwater migration 
rates. Proposed paragraph (d) would continue to allow the regulatory 
authority to approve a permit revision to otherwise modify the 
parameters monitored and the sampling frequency under certain 
conditions. We invite comment on whether we should establish a minimum 
sampling frequency or place other restrictions on the regulatory 
authority's ability to modify monitoring requirements.
    However, as in the similar provision in proposed 30 CFR 816.35 
relating to groundwater monitoring, we propose to add requirements that 
the permittee demonstrate that future changes in surface-water quantity 
or quality are unlikely and that the operation has preserved or 
restored the biological condition of perennial and intermittent streams 
within the permit and adjacent areas. See proposed paragraphs (d)(1) 
and (2)(iii). The additional criteria are intended to ensure that 
surface-water monitoring requirements are not reduced or modified 
prematurely.
    In addition, we propose to replace the requirement in existing 30 
CFR 816.41(e)(3)(i) for a demonstration that the water quantity and 
quality are suitable to support approved postmining land uses with a 
requirement for a demonstration that the operation has maintained the 
availability and quality of surface water in a manner that can support 
existing and reasonably foreseeable uses and that does not preclude 
attainment of designated uses under section 101(a) or 303(c) of the 
Clean Water Act.\575\ Our

[[Page 44547]]

proposed replacement language parallels the terminology of our proposed 
definition of material damage to the hydrologic balance outside the 
permit area in 30 CFR 701.5, which also relies upon existing, 
reasonably foreseeable, and designated uses under section 101(a) or 
303(c) of the Clean Water Act. We propose to retain the requirement in 
the last clause of existing 30 CFR 816.41(e)(3)(i) for a demonstration 
that the water rights of other users have been protected or replaced.
---------------------------------------------------------------------------

    \575\ 33 U.S.C. 1251(a) and 1313(c), respectively.
---------------------------------------------------------------------------

Proposed Paragraph (e)
    Proposed paragraph (e) corresponds to the second sentence of 
existing 30 CFR 816.41(e)(1), which provides that the regulatory 
authority may require additional monitoring when necessary. We propose 
to modify the existing language to specify that the regulatory 
authority must require additional monitoring when information available 
to the regulatory authority indicates that additional monitoring is 
necessary to protect the hydrologic balance, detect hydrologic changes, 
or meet other requirements of the regulatory program. We also propose 
to specify that the regulatory authority must issue a permit revision 
order under Sec.  774.10(b) when requiring changes to the monitoring 
plan approved in the permit.
Proposed Paragraph (f)
    Like existing 30 CFR 816.41(e)(4), proposed paragraph (f) would 
require that the permittee install, maintain, operate, and, when no 
longer needed, remove all equipment, structures, and other devices used 
in conjunction with monitoring surface water.
8. Section 816.37: How must I monitor the biological condition of 
streams?
    We propose to add this section to require monitoring of the 
biological condition of perennial and intermittent streams, consistent 
with the monitoring plan approved in the permit in accordance with 
proposed 30 CFR 780.23(c). The proposed rule would require annual 
monitoring during mining and reclamation until the entire bond amount 
for the monitored area has been fully released under proposed 30 CFR 
800.42(d). The annual frequency is intended to provide sufficient data 
to evaluate the impacts of mining and reclamation without depleting the 
stream segment of aquatic life, as more frequent sampling might do. 
Monitoring would enable the permittee and the regulatory authority to 
determine whether the predictions in the permit application are 
accurate and to take timely corrective measures if the predictions turn 
out to be inaccurate. The proposed monitoring requirements generally 
parallel the requirements for water monitoring under 30 CFR 816.35 and 
8816.36, but in simplified form.
9. Section 816.38: How must I handle acid-forming and toxic-forming 
materials?
    Proposed section 816.38 would replace and revise existing 30 CFR 
816.41(f), which requires that drainage from acid-forming and toxic-
forming materials into surface water and groundwater be avoided by 
appropriate storage, burial, and treatment practices. We propose to 
flesh out the existing rule to more completely implement section 
515(b)(14) of SMCRA,\576\ which requires that all acid-forming 
materials and toxic materials be ``treated or buried and compacted or 
otherwise disposed of in a manner designed to prevent contamination of 
ground or surface waters,'' and section 515(b)(3) of SMCRA,\577\ which 
provides that ``overburden or spoil shall be shaped and graded in such 
a way as to prevent slides, erosion, and water pollution.'' Proposed 30 
CFR 816.38 also would more completely implement section 515(b)(10) of 
SMCRA,\578\ which provides that surface coal mining and reclamation 
operations must be conducted to ``minimize the disturbances to the 
prevailing hydrologic balance at the mine-site and in associated 
offsite areas and to the quality and quantity of water in surface and 
ground water systems both during and after surface coal mining 
operations and during reclamation by *** avoiding acid or other toxic 
mine drainage.''

    \576\ 30 U.S.C. 1265(b)(14).
    \577\ 30 U.S.C. 1265(b)(3).
    \578\ 30 U.S.C. 1265(b)(10).
---------------------------------------------------------------------------

    We propose to revise the introductory text of 30 CFR 816.38 to 
require that the permittee use the best technology currently available 
to handle acid-forming and toxic-forming materials in a manner that 
will avoid the creation of acid or toxic mine drainage into surface 
water and groundwater. The phrase ``best technology currently 
available'' does not appear in the sections of SMCRA mentioned above. 
However, application of this standard to the handling of acid-forming 
and toxic-forming materials is appropriate because section 515(b)(24) 
of SMCRA \579\ requires use of the best technology currently available 
to minimize adverse impacts on fish, wildlife, and related 
environmental values. The handling of acid-forming and toxic-forming 
materials would affect surface-water and groundwater quality, which are 
related environmental values in the context of fish and wildlife.
---------------------------------------------------------------------------

    \579\ 30 U.S.C. 1265(b)(24).
---------------------------------------------------------------------------

    Proposed paragraphs (a) through (f) contain more specific 
provisions on how the permittee must implement this requirement.
    Proposed paragraph (a) would require that the permittee identify 
potential acid-forming and toxic-forming materials in overburden strata 
and the stratum immediately below the lowest coal seam to be mined. We 
invite comment on whether there are generally-accepted tests for 
potential acid-forming and toxic-forming materials in overburden strata 
that the final rule should require.
    Proposed paragraph (a) also would require that the permittee cover 
exposed coal seams and the stratum immediately beneath the lowest coal 
seam mined with a layer of compacted material with a hydraulic 
conductivity at least two orders of magnitude lower than the hydraulic 
conductivity of the adjacent less-compacted spoil to minimize contact 
and interaction with water. Covering the coal seam and the underlying 
stratum with material that has a lower permeability than the adjacent 
spoil would reduce the amount of water that could either reach or leave 
the coal seam and underlying stratum. Reduced water transmission will 
inhibit both the creation and migration of acid or toxic mine drainage. 
Use of materials with such a great difference in permeability should 
result in the low-permeability material behaving as an aquitard. The 
groundwater and infiltrating surface water should preferentially flow 
through the surrounding high-permeability material and not through the 
low-permeability material encapsulating the acid-forming or toxic-
forming materials.
    Proposed paragraph (b) would require that the permittee identify 
the anticipated postmining groundwater level for all locations at which 
acid-forming or toxic-forming materials are to be placed. This 
information is critical to a determination of whether the materials 
will remain in an environment that will prevent formation or migration 
of acid or toxic mine drainage.
    Proposed paragraph (c) would require that the permittee selectively 
handle and place acid-forming and toxic-forming materials within the 
backfill in accordance with the plan approved in the permit, unless the 
permit allows placement of those materials in an excess spoil fill or a 
coal mine waste refuse pile. Proposed paragraph (c) identifies three 
acceptable handling techniques for acid-forming and toxic-forming 
materials to be placed in the

[[Page 44548]]

backfill: (1) Complete isolation of acid-forming and toxic-forming 
materials from contact or interaction with surface water or groundwater 
by surrounding those materials with compacted material with a hydraulic 
conductivity at least two orders of magnitude lower than the hydraulic 
conductivity of the adjacent less-compacted spoil; (2) placement of 
acid-forming and toxic-forming materials in a location below the water 
table where they will remain fully saturated at all times, provided 
that the permittee demonstrates, and the regulatory authority finds in 
writing in the permit, that complete saturation will prevent the 
formation of acid or toxic leachate; and (3) treatment to neutralize 
the acid-forming and toxic-forming potential of those materials. The 
last technique may be used in combination with either of the first two 
methods. Under the proposed rule, the permittee must use the technique 
or combination of techniques approved in the permit in accordance with 
proposed 30 CFR 780.12(d)(4). The permittee must demonstrate and the 
regulatory authority must confirm that the selected technique will be 
effective for each parameter of concern. For example, a technique that 
may be effective in preventing the formation of acid drainage might not 
be effective in preventing leaching of selenium. The regulatory 
authority may require that the permittee or permit applicant submit 
additional information, including fate and transport modeling, if 
deemed necessary.
    Isolation of acid-forming and toxic-forming materials from contact 
with groundwater or surface water can be accomplished by completely 
surrounding those materials with compacted material with a hydraulic 
conductivity at least two orders of magnitude lower than the hydraulic 
conductivity of the adjacent less-compacted spoil to minimize 
interaction with water. Situations requiring saturation rather than 
isolation arise most frequently in the relatively flat terrain of 
coalfields in the Midwest and the West. Saturation may not be suitable 
for materials with the potential for forming toxic compounds through 
processes other than pyritic oxidation.
    Proposed paragraph (d) would allow placement of acid-forming and 
toxic-forming materials in an excess spoil fill or a coal mine waste 
refuse pile when approved in the permit. The proposed rule would 
require the use of isolation or treatment or a combination of those 
techniques whenever the permittee places acid-forming or toxic-forming 
materials in an excess spoil fill or a coal mine waste refuse pile. The 
proposed rule would not authorize use of the saturation technique 
because saturation could jeopardize the stability of the fill or refuse 
pile. Saturation also could result in discharges with high levels of 
total dissolved solids, which in turn could adversely impact the 
biological condition of streams and cause material damage to the 
hydrologic balance outside the permit area.
    Alternatively, prohibition of placement of acid-forming or toxic-
forming materials in an excess spoil fill would provide an additional 
layer of protection against the development of seeps containing acid or 
toxic mine drainage. We invite comment on whether we should revise our 
rule to include such a prohibition.
    Proposed paragraph (e) would modify the requirements in existing 30 
CFR 816.41(f)(1)(ii) for temporary storage of acid-forming and toxic-
forming materials to emphasize that storage may be used only when the 
regulatory authority specifically approves temporary storage as 
necessary and finds in writing in the permit that the proposed storage 
method will protect surface water and groundwater by preventing 
erosion, the formation of polluted runoff, and the infiltration of 
polluted water into aquifers. The proposed rule would require that the 
regulatory authority specify a maximum time for temporary storage, 
which may not exceed the period until burial first becomes feasible. We 
also propose to add a provision prohibiting temporary storage if doing 
so would result in a risk of adverse impacts to the biological 
condition of perennial or intermittent streams. Minimizing the need 
for, and duration of, temporary storage is critical because the 
oxidation of pyritic materials continues while the material is exposed. 
Precipitation may infiltrate and percolate through the pile, which can 
result in an increase in the concentration of total dissolved solids 
leaving the site. The weathering products of pyrite oxidation 
essentially become ``stored acidity,'' which presents a greater risk to 
the hydrologic balance if the permanent placement technique ultimately 
is not successful. Our proposed revisions to the temporary storage 
requirements for acid-forming and toxic-forming materials would improve 
implementation of section 515(b)(10) of SMCRA.\580\
---------------------------------------------------------------------------

    \580\ 30 U.S.C. 1265(b)(10). This provision of SMCRA specifies 
that surface coal mining and reclamation operations must be 
conducted to--
    minimize the disturbances to the prevailing hydrologic balance 
at the mine-site and in associated offsite areas and to the quality 
and quantity of water in surface and ground water systems both 
during and after surface coal mining operations and during 
reclamation by--
    (A) avoiding acid or other toxic mine drainage by such measures 
as, but not limited to--
    (i) preventing or removing water from contact with toxic 
producing deposits[.]
---------------------------------------------------------------------------

    Proposed paragraph (f) would require that disposal, treatment, and 
storage practices for acid-forming and toxic-forming materials be 
consistent with other material handling and disposal provisions of the 
regulatory program. This paragraph is substantively identical to 
existing 30 CFR 816.41(f)(2).
10. Section 816.40: What responsibility do I have to replace water 
supplies?
    Proposed 30 CFR 816.40 would replace and revise existing 30 CFR 
816.41(h), which contains performance standards to implement section 
717(b) of SMCRA.\581\ That paragraph of SMCRA provides that--
---------------------------------------------------------------------------

    \581\ 30 U.S.C. 1307(b).

The operator of a surface coal mine shall replace the water supply 
of an owner of interest in real property who obtains all or part of 
his supply of water for domestic, agricultural, industrial, or other 
legitimate use from an underground or surface source where such 
supply has been affected by contamination, diminution, or 
interruption proximately resulting from such surface coal mine 
---------------------------------------------------------------------------
operation.

    Proposed 30 CFR 816.40 would further flesh out the requirements of 
this statutory provision by incorporating paragraphs (a) and (b) of the 
existing definition of ``replacement of water supply'' in 30 CFR 701.5. 
We propose to move those paragraphs to 30 CFR 816.40(a)(2) through (4) 
because they effectively function as performance standards and are not 
definitional in nature. We also propose to require adherence to the 
water supply replacement provisions of proposed 30 CFR 780.22(b) when 
the permit anticipates that damage to water supplies will occur. 
Finally, we propose to add the following provisions that would apply 
when unanticipated damage to a protected water supply occurs:
     The permittee would have to provide an emergency temporary 
water supply within 24 hours of notification of unanticipated damage to 
a protected water supply. The temporary supply must be adequate in 
quantity and quality to meet normal household needs.
     The permittee would have to develop and submit a plan for 
a permanent replacement supply to the regulatory authority within 30 
days of receiving notice of unanticipated damage.

[[Page 44549]]

     The permittee would have to provide a permanent 
replacement water supply within 2 years of receiving notice of 
unanticipated damage.
    The proposed timeframes for replacement of water supplies for which 
damage is unanticipated differ somewhat from those set forth in the 
preamble to the existing definition of ``replacement of water supply'' 
in 30 CFR 701.5. That preamble defines prompt replacement as providing 
an emergency drinking water supply within 48 hours of notification, a 
temporary water supply hookup within 2 weeks of notification, and a 
permanent replacement supply within 2 years of notification.\582\ We 
propose to replace the timeframes in that preamble with the times set 
forth in proposed 30 CFR 816.40 as discussed above. The proposed 
timeframes would better protect society and the environment from the 
adverse effects of surface coal mining operations, in keeping with the 
purpose of SMCRA set forth in section 102(a) of the Act.\583\

---------------------------------------------------------------------------

11. Section 816.41: Under what conditions may I discharge to an 
underground mine?
    Proposed section 816.41 would inlude existing 30 CFR 816.41(i) and 
add four new requirements that must be met before the regulatory 
authority may approve a proposed discharge to any type of underground 
mine. First, proposed paragraph (a)(1)(ii) would require a 
demonstration that the discharge will be made in a manner that will 
prevent material damage to the hydrologic balance of the area in which 
the underground mine receiving the discharge is located. Second, 
proposed paragraph (a)(1)(iii) would require a demonstration that the 
discharge will be made in a manner that will not adversely impact the 
biological condition of perennial or intermittent streams. Third, 
proposed paragraph (a)(3)(ii) would allow the regulatory authority to 
approve discharges of water that exceed the effluent limitations for pH 
and total suspended solids only if available evidence indicates that 
there is no direct hydrologic connection between the underground mine 
and other waters and that the discharge would not cause material damage 
to the hydrologic balance outside the permit area. All three of the 
proposed revisions discussed above are intended to more fully implement 
section 510(b)(3) of SMCRA,\584\ which prohibits approval of a permit 
application unless the applicant demonstrates, and the regulatory 
authority finds, that the proposed operation has been designed to 
prevent material damage to the hydrologic balance outside the permit 
area.
---------------------------------------------------------------------------

    \584\ 30 U.S.C. 1260(b)(3).
---------------------------------------------------------------------------

    The fourth proposed revision would add paragraph (a)(5), which 
would require that the permit applicant obtain written permission from 
the owner of the mine into which the discharge is to be made and 
provide a copy of that authorization to the regulatory authority.
12. Section 816.42: What are my responsibilities to comply with water 
quality standards and effluent limitations?
    We propose to redesignate existing 30 CFR 816.42 as paragraph (a) 
of this section. We also propose to revise this paragraph by replacing 
the reference to the effluent limitations in 40 CFR part 434 with a 
reference to the effluent limitations established in the NPDES permit 
for the operation. This change would make our regulations consistent 
with the policy and practice of the EPA, which recognizes only the 
effluent limitations in the NPDES permit as being enforceable.
    Proposed paragraph (b) would require that discharges of overburden 
(including excess spoil), coal mine waste, and other materials into 
waters of the United States be made in compliance with section 404 of 
the Clean Water Act \585\ and its implementing regulations. While the 
language would be new, the requirement would not--SMCRA permittees 
always have been required to comply with the Clean Water Act, as 
emphasized in section 702(a) of SMCRA,\586\ which provides that 
``[n]othing in this Act shall be construed as superseding, amending, 
modifying, or repealing'' the Clean Water Act (33 U.S.C. 1251 et seq.), 
any rule or regulation adopted under the Clean Water Act, any state 
laws enacted pursuant to the Clean Water Act, ``or other Federal laws 
relating to preservation of water quality.'' We invite comment on 
whether the provisions of proposed paragraph (b) should be considered 
informational in nature like the provisions of section 702(a) of SMCRA 
\587\ or whether they should be directly enforceable under SMCRA.

    \586\ 30 U.S.C. 1292(a).
    \587\ Id.
---------------------------------------------------------------------------

    Proposed paragraphs (c) through (e) would establish enforceable 
performance standards requiring proper operation and maintenance of 
water treatment facilities and environmentally appropriate disposition 
of precipitates from those facilities. They are intended to improve 
implementation of section 515(b)(10)(A)(ii) of SMCRA,\588\ which 
requires that surface coal mining and reclamation operations avoid acid 
or other toxic mine drainage by ``treating drainage to reduce toxic 
content which adversely affects downstream water upon being released to 
water courses.''
---------------------------------------------------------------------------

    \588\ 30 U.S.C. 1265(b)(10)(A)(ii).
---------------------------------------------------------------------------

    Specifically, proposed paragraph (c) would require the permittee to 
construct water treatment facilities for discharges from the operation 
as soon as the need for those facilities becomes evident. Proposed 
paragraph (d) would require that the permittee remove precipitates and 
otherwise maintain all water treatment facilities involving the use of 
settling ponds or lagoons as necessary to maintain the functionality of 
the ponds or lagoons. The permittee would be required to dispose of the 
precipitates removed either in an approved solid waste landfill or in a 
location within the permit area. Proposed paragraph (e) would require 
that the permittee operate and maintain water treatment facilities 
until the regulatory authority authorizes their removal based upon 
monitoring data demonstrating that influent to the facilities meets all 
applicable water quality standards and effluent limits without 
treatment.
13. Section 816.43: How must I construct and maintain diversions and 
other channels to convey water?
    We propose to revise this section to reflect plain language 
principles. In addition, we propose several substantive changes. First, 
proposed paragraph (a)(3) would require the construction of channels 
that meet temporary diversion design criteria to convey surface runoff 
to siltation structures whenever the sedimentation control plan 
approved in the permit pursuant to 30 CFR 816.45 involves the use of 
siltation structures. This requirement would not apply if the entire 
disturbed area would naturally drain to the siltation structure without 
the construction of channels. Requiring that these channels meet 
temporary diversion design criteria would minimize the potential for 
failure and the resulting possibility of offsite impacts. Diversion 
failures have resulted in subsequent failures of larger structures. For 
example, in West Virginia in 2003, the failure of a diversion ditch 
caused erosion and the breaching of a reclaimed impoundment, resulting 
in a flow of water, slurry, and coarse refuse downstream. This event

[[Page 44550]]

isolated residents along Ned's Branch, blocked roads and a major 
railroad, and contaminated the Guyandotte River.
    Existing 30 CFR 816.43(a) requires that diversions be designed to 
minimize adverse impacts to the hydrologic balance within the permit 
and adjacent areas. Proposed paragraph (a)(4)(ii) would clarify that 
this provision includes a requirement to minimize adverse impacts to 
perennial and intermittent streams within that area.
    Existing 30 CFR 816.43(a) requires that diversions be designed to 
``prevent material damage outside the permit area.'' Proposed paragraph 
(a)(4)(iii) would revise this language to require that diversions be 
designed to prevent material damage to the hydrologic balance outside 
the permit area. The revised language would make this provision 
consistent with the terminology of 30 CFR 773.15(e) and section 
510(b)(3) of SMCRA,\589\ which require that surface coal mining and 
reclamation operations be designed to prevent material damage to the 
hydrologic balance outside the permit area.
---------------------------------------------------------------------------

    \589\ 30 U.S.C. 1260(b)(3).
---------------------------------------------------------------------------

    We propose to combine existing 30 CFR 816.43(a)(2)(ii) and (c)(3) 
into a new paragraph (a)(5)(ii). Existing paragraph (a)(2)(ii) provides 
that each diversion and its appurtenant structures must be designed, 
located, constructed, maintained, and used to provide protection 
against flooding and resultant damage to life and property. Existing 
paragraph (c)(3) states that this requirement will be deemed met when 
the combination of channel, bank, and floodplain configuration is 
adequate to safely pass the peak runoff of a 2-year, 6-hour 
precipitation event for a temporary diversion and a 10-year, 6-hour 
precipitation event for a permanent diversion. Proposed paragraph 
(a)(5)(ii) would replace existing paragraph (a)(2)(ii) with a slightly 
modified version of existing paragraph (c)(3) because existing 
paragraph (c)(3) effectively negates existing paragraph (a)(2)(ii). 
Proposed paragraph (a)(5)(ii) would not contain the reference to 
floodplain configuration in existing paragraph (c)(3) because use of a 
floodplain to convey flows from storm runoff is appropriate in 
naturally-functioning streams and in restored streams, but not with 
temporary or permanent diversions.
    Proposed paragraph (a)(5)(ii) also would require that each 
diversion be designed using the appropriate regional NRCS synthetic 
storm distribution to determine peak flows. The preamble to proposed 30 
CFR 780.29 explains the rationale for this proposed requirement.
    Proposed paragraph (a)(5)(iii) would include existing paragraph 
(a)(2)(iii). We propose to add a reference to runoff outside the permit 
area to be consistent with the underlying statutory provision in 
section 515(b)(10)(B)(i) of SMCRA,\590\ which requires that surface 
coal mining operations be conducted ``so as to prevent, to the extent 
possible using the best technology currently available, additional 
contributions of suspended solids to streamflow, or runoff outside the 
permit area.''
---------------------------------------------------------------------------

    \590\ 30 U.S.C. 1265(b)(10)(B)(i).
---------------------------------------------------------------------------

    The last sentence of existing paragraph (a)(3) and the entirety of 
existing paragraph (b) contain approval, design, and construction 
requirements for temporary and permanent diversions of perennial, 
intermittent, and ephemeral streams. We propose to move the approval 
and design provisions to 30 CFR 780.28(c) and the construction 
requirements to 30 CFR 816.57(b) to consolidate requirements concerning 
activities in, through, or adjacent to streams in those sections. 
Proposed paragraph (b) would specify that 30 CFR 780.28 and 816.57 
contain additional requirements applicable to diversions of perennial 
and intermittent streams.
    Lastly, we propose to revise paragraph (c)(1) of the existing rules 
to limit the scope of paragraph (c), which applies to diversions of 
miscellaneous flows, to surface-water flows other than perennial and 
intermittent streams. The existing rule is internally inconsistent in 
that it specifically includes groundwater discharges, but expressly 
excludes perennial and intermittent streams. However, any flow 
resulting from a groundwater discharge would be a perennial or 
intermittent stream under both the existing and proposed definitions of 
those terms in 30 CFR 701.5. Therefore, diversions of groundwater 
discharges would be subject to the stream-channel diversion 
requirements referenced in proposed paragraph (b) rather than standards 
for miscellaneous flows under paragraph (c).
    We invite comment on whether we should revise paragraph (c) to 
apply the same design events for temporary and permanent diversions of 
miscellaneous flows as apply to temporary and permanent diversions of 
perennial and intermittent streams because there is no readily apparent 
hydrologic reason to apply different standards based on the flow regime 
of the stream. Instead, it may be more logical to prescribe design 
events based upon the length of time that the diversion is expected to 
remain in existence; i.e., whether it is temporary or permanent. Under 
this approach, temporary diversions of miscellaneous flows would have 
to be designed and constructed to safely pass the peak runoff from the 
10-year, 6-hour precipitation event rather than the 2-year, 6-hour 
event. Similarly, permanent diversions of miscellaneous flows would 
have to be designed and constructed to safely pass the peak runoff from 
the 100-year, 6-hour precipitation event rather than the 10-year, 6-
hour event. We also invite comment on whether we should raise the 
design event for temporary diversions to the 25-year, 6-hour event to 
provide an added margin of safety.
14. Section 816.45: What sediment control measures must I use?
    We propose to remove the second sentence of 30 CFR 816.45(b), which 
reads as follows: ``The sedimentation storage capacity of practices in 
and downstream from the disturbed areas shall reflect the degree to 
which successful mining and reclamation techniques are applied to 
reduce erosion and control sediment.'' The meaning of this sentence is 
unclear, but it appears to be predicated on the assumption that all 
mines will have a sedimentation pond or other siltation structure 
located downstream of the disturbed area. That assumption is 
inconsistent with the court decision remanding former 30 CFR 
816.46(b)(2) (1983).\591\ Furthermore, not all sediment control 
practices include sedimentation storage capacity. Therefore, we propose 
to remove this sentence to avoid any conflict with either the court 
decision or current technology.

41961 (Nov. 20, 1986).
---------------------------------------------------------------------------

15. Section 816.46: What requirements apply to siltation structures?
    We propose to remove existing paragraph (b)(1) of this section 
because it duplicates 30 CFR 816.45(a)(1), both of which require use of 
the best technology currently available to prevent additional 
contributions of suspended solids to streamflow or runoff outside the 
permit area to the extent possible. Section 816.45 is the more 
appropriate location for this provision because section 816.46 covers 
only siltation structures, whereas section 816.45 encompasses all 
methods of sediment control. Section 816.45 sets forth various measures 
and techniques that may constitute the best technology currently 
available for sediment control,

[[Page 44551]]

although applicants and regulatory authorities are not limited to those 
measures and techniques.
    Paragraph (b)(2) of 30 CFR 816.46 and 817.46 (1983) required that 
all surface drainage from the disturbed area be passed through a 
siltation structure before leaving the permit area. In essence, that 
paragraph prescribed siltation structures (sedimentation ponds and 
other treatment facilities with point-source discharges) as the best 
technology currently available for sediment control. However, paragraph 
(b)(2) was struck down upon judicial review because the court found 
that the preamble to the rulemaking in which it was adopted did not 
articulate a sufficient basis for the rule under the Administrative 
Procedure Act. The court stated that the preamble did not adequately 
discuss the benefits and drawbacks of siltation structures and 
alternative sediment control methods and did not enable the court ``to 
discern the path taken by [the Secretary] in responding to commenters' 
concerns'' that siltation structures in the West are not the best 
technology currently available. See In re: Permanent Surface Mining 
Regulation Litigation II, Round III, 620 F. Supp. 1519, 1566-1568 
(D.D.C. July 15, 1985).
    On November 20, 1986 (51 FR 41961), we suspended the rules struck 
down by the court. In a technical rule that corrected various errors in 
citations, cross-references, and other inadvertent errors, we lifted 
that suspension and removed paragraph (b)(2) from our regulations on 
September 29, 2010 (75 FR 60272, 60275). However, on February 14, 2014, 
the court's decision in NPCA reinstated the version of 30 CFR 816.46(b) 
in effect before adoption of the stream buffer zone rule on December 
12, 2008. This action had the effect of reinstating the suspension, 
which we codified in a final rule published on December 22, 2014. See 
79 FR 76227-76233. We now propose to lift this suspension, remove 
paragraph (b)(2) of sections 816.46 and 817.46, and redesignate the 
remaining paragraphs of those sections accordingly.
    In addition, we propose to redesignate as paragraph (b)(1) the 
provision in existing paragraph (b)(3) requiring that the permittee 
construct siltation structures for an area before initiating any 
surface mining activities in the area. We also propose to revise this 
paragraph to clarify that the requirement to construct siltation 
structures applies only when the approved permit requires the use of 
siltation structures to achieve the sediment control requirements of 30 
CFR 816.45. This revision is needed because, as the courts have 
recognized, siltation structures are not always the best technology 
currently available for sediment control.\592\ Proposed paragraph 
(b)(2) would retain only the requirement in existing paragraph (b)(3) 
that the construction of siltation structures be certified by a 
qualified registered professional engineer or a qualified registered 
professional land surveyor.

1985), as discussed at 73 FR 75854 (Dec. 12, 2008).
---------------------------------------------------------------------------

    Finally, we propose to--
     Revise existing paragraph (b)(5), which we propose to 
redesignate as paragraph (b)(4), to remove the prohibition on removing 
siltation structures sooner than 2 years after the last augmented 
seeding. The standard is too inflexible and it is arguably inconsistent 
with the decision in PSMRL II, Round III discussed above, in which the 
court held that we had not demonstrated that siltation structures are 
always the best technology currently available to control sediment in 
runoff from the minesite. Applying that rationale, the permittee should 
have the option of using other methods of sediment control in lieu of 
retaining the siltation structures for 2 years after the last augmented 
seeding. In addition, the remaining standard in the rule, which 
prohibits removal of siltation structures until the disturbed area is 
stabilized and revegetated, is sufficient to ensure an appropriate 
level of environmental protection.
     Revise existing paragraph (b)(6), which we propose to 
redesignate as paragraph (b)(5), to clarify that the exemption for 
sedimentation ponds approved by the regulatory authority for retention 
as permanent impoundments under 30 CFR 816.49(b) is contingent upon 
meeting the maintenance requirements of 30 CFR 800.42(c)(5). The latter 
rule implements the statutory provision in section 519(c)(2) of SMCRA 
\593\ establishing bond release requirements for silt dams to be 
retained as permanent impoundments.
---------------------------------------------------------------------------

    \593\ 30 U.S.C. 1269(c)(2).
---------------------------------------------------------------------------

     Remove existing paragraph (c)(1)(i), which provides that 
sedimentation ponds must be used individually or in series. This 
provision adds nothing meaningful to our regulations because there is 
no other way in which sedimentation ponds could be used.
     Revise existing paragraph (c)(1)(ii), which we propose to 
redesignate as paragraph (c)(1)(i), to provide that the prohibition on 
locating sedimentation ponds in stream channels applies to both 
perennial and intermittent stream channels, not just to perennial 
stream channels as in the existing rule. In addition, we propose to 
clarify that any exceptions to this prohibition must comply with 30 CFR 
780.28, which contains the permitting requirements for activities in, 
through, or adjacent to perennial and intermittent streams, and the 
performance standards concerning sedimentation control structures in 
streams in 30 CFR 816.57(c). The statutory basis for these proposed 
changes is the same as the statutory basis for the stream protection 
measures proposed in 30 CFR 780.28.
     Revise existing paragraph (c)(1)(iii)(H), which we propose 
to redesignate as paragraph (c)(1)(ii)(H), to replace the prohibition 
on the use of acid-forming or toxic-forming coal processing waste in 
the construction of sedimentation ponds with a prohibition on the use 
of any acid-forming or toxic-forming materials in the construction of 
sedimentation ponds. This change is both appropriate and necessary 
because coal processing waste is not the only form of acid-forming or 
toxic-forming materials that could conceivably be used in the 
construction of sedimentation ponds. The proposed change also would 
better implement section 515(b)(10)(A)(i) of SMCRA,\594\ which requires 
the avoidance of acid or other toxic mine drainage by ``preventing or 
removing water from contact with toxic producing deposits.''

---------------------------------------------------------------------------

16. Section 816.47: What requirements apply to discharge structures for 
impoundments?
    We propose to revise this section by updating the terminology to 
reflect our 1983 rulemaking in which we introduced the term ``coal mine 
waste'' and replaced the term ``coal processing waste dams and 
embankments'' with coal mine waste impounding structures. See 48 FR 
44006 (Sept. 26, 1983).
17. Section 816.49: What requirements apply to impoundments?
    We propose to update the hazard classifications and incorporations 
by reference in existing paragraph (a)(1) of this section to be 
consistent with those in 30 CFR 780.25, which contains the permitting 
requirements for impoundments. Specifically we propose to update the 
incorporation by reference of the NRCS publication ``Earth Dams and 
Reservoirs,'' Technical Release No. 60 (210-VI-TR60, October 1985), by 
replacing the reference to the October 1985 edition with a reference to 
the superseding July 2005 edition. Consistent with the terminology in 
the newer edition, we proposed to replace

[[Page 44552]]

references to Class B or C dam criteria throughout section 816.49 with 
references to Significant Hazard Class or High Hazard Class dam 
criteria, respectively. Only the terminology has changed--the actual 
criteria remain the same as before. The newer publication is not 
available from the National Technical Information Service, but is 
available online from the NRCS. Consequently, we propose to delete the 
ordering information pertinent to the National Technical Information 
Service and replace it with the URL (Internet address) at which the 
publication may be reviewed and from which it may be downloaded without 
charge.
    We propose to revise our permanent impoundment requirements in 
paragraph (b) by adding three new criteria for approval of permanent 
impoundments. Proposed paragraph (b)(7) would require a demonstration 
that approval of the impoundment would not result in retention of spoil 
piles or ridges that are inconsistent with the definition of 
approximate original contour. Proposed paragraph (b)(8) would require a 
demonstration that approval of the impoundment would not result in the 
creation of an excess spoil fill elsewhere within the permit area. 
These two proposed changes are intended to provide a safeguard against 
the retention of final-cut impoundments and associated spoil ridges 
that are inconsistent with the requirement in section 515(b)(3) of 
SMCRA \595\ to ``restore the approximate original contour of the land 
with all highwalls, spoil piles, and depressions eliminated.''
---------------------------------------------------------------------------

    \595\ 30 U.S.C. 1265(b)(3).
---------------------------------------------------------------------------

    Proposed paragraph (b)(9) would require a demonstration that the 
impoundment has been designed with dimensions and other characteristics 
that would enhance fish and wildlife habitat to the extent that doing 
so is not inconsistent with the intended use of the impoundment. This 
provision would improve implementation of section 515(b)(24) of 
SMCRA,\596\ which requires use of the best technology currently 
available to the extent possible to enhance fish, wildlife, and related 
environmental values where practicable.

18. Section 816.57: What additional performance standards apply to 
activities in, through, or adjacent to a perennial or intermittent 
stream?
General Discussion of Basis for Proposed Changes
    We propose to replace existing 30 CFR 816.57 with provisions that 
would better protect perennial and intermittent streams, consistent 
with the June 11, 2009, MOU discussed in Part VI of this preamble. Part 
II of this preamble summarizes both the terrestrial impacts of surface 
coal mining operations and the impacts of those operations on streams, 
as documented by scientific studies. Among other things, our proposed 
rule is intended to prevent or minimize the adverse impacts on fish, 
wildlife, and related environmental values, including streams, 
documented in those studies. The authority for our proposed revisions 
to 30 CFR 816.57 is identical to our authority for the corresponding 
permitting requirements in proposed 30 CFR 780.28 and is discussed at 
length in the introductory portion of the preamble to that proposed 
rule.
Proposed Paragraph (a)
    Existing paragraph (a) provides that ``[n]o land within 100 feet of 
a perennial or intermittent stream shall be disturbed by surface mining 
activities, unless the regulatory authority specifically authorizes 
surface mining activities closer to, or through, such a stream.'' The 
rule further specifies that the regulatory authority may provide that 
authorization only upon finding that the activities will not cause or 
contribute to the violation of applicable state or federal water 
quality standards and that they will not adversely affect the water 
quantity and quality or other environmental resources of the stream. 
The regulatory authority also must find that if there will be a 
temporary or permanent stream-channel diversion, it will comply with 30 
CFR 816.43, which contains the performance standards for diversions.
    As described in more detail in Part VI of this preamble, existing 
paragraph (a) has been subject to differing interpretations over the 
years. In an effort to provide greater clarity, proposed paragraph 
(a)(1) would retain only the provision that prohibits disturbance of 
land within 100 feet of a perennial or intermittent stream without 
regulatory authority approval. We propose to replace the criteria for 
regulatory authority approval in the existing rule with new permit 
application requirements and approval criteria and requirements in 30 
CFR 780.28. We also propose to expand protections for perennial and 
intermittent streams, as discussed below.
    Proposed paragraph (a)(1) would prohibit the conduct of surface 
mining activities in or through a perennial or intermittent stream, or 
that would disturb the surface of land within 100 feet, measured 
horizontally,\597\ of a perennial or intermittent stream, unless the 
regulatory authority authorizes those activities in the permit after 
making the findings that would be required by proposed 30 CFR 780.28. 
Part VI of this preamble discusses the history of stream buffer zone 
rules under SMCRA, all of which have established a minimum buffer zone 
width of 100 feet on either side of the stream. The preamble to our 
1979 rules explains the rationale for that width. See 44 FR 15176-15177 
(Mar. 13, 1979). A more recent literature review documents that a 
vegetative filter strip width of 100 feet generally will attenuate 
sediment in runoff from disturbed areas.\598\

preamble for an explanation of how this distance must be measured.

---------------------------------------------------------------------------

    Section 515(b)(10)(B)(i) of SMCRA,\599\ which, in relevant part, 
requires that surface coal mining operations be conducted ``so as to 
prevent, to the extent possible using the best technology currently 
available, additional contributions of suspended solids to streamflow, 
or runoff outside the permit area,'' provides the primary statutory 
authority for the minimum buffer width that we propose to establish in 
paragraph (a)(1). The prohibition on disturbing the buffer zone also 
would implement section 515(b)(24) of SMCRA,\600\ which provides that 
surface coal mining and reclamation operations must be conducted to 
minimize disturbances to and adverse impacts on fish, wildlife, and 
related environmental values to the extent possible using the best 
technology currently available.

    \600\ 30 U.S.C. 1265(b)(24).
---------------------------------------------------------------------------

    Proposed paragraph (a)(2) would reiterate that surface mining 
activities may be conducted in waters of the United States only if the 
permittee first obtains all necessary authorizations, certifications, 
and permits under the Clean Water Act, 33 U.S.C. 1251 et seq. This 
proposed paragraph is an informational provision that would be 
consistent with section 702(a) of SMCRA,\601\ which provides that 
``[n]othing in this Act shall be construed as superseding, amending, 
modifying, or repealing'' the Clean Water Act, any rule or regulation 
adopted under the Clean Water Act, or any state laws enacted pursuant 
to the Clean Water Act. Proposed paragraph (a)(2) would operate in 
tandem with proposed 30

[[Page 44553]]

CFR 773.17(h), which would add a new permit condition requiring that 
the permittee obtain all necessary authorizations, certifications, and 
permits in accordance with Clean Water Act requirements before 
conducting any activities that require approval or authorization under 
the Clean Water Act. Permit conditions are directly enforceable under 
SMCRA. Therefore, addition of the permit condition in proposed 30 CFR 
773.17(h) would mean that the SMCRA regulatory authority must take 
enforcement action if the permittee does not obtain all necessary Clean 
Water Act authorizations, certifications, and permits before beginning 
any activity under the SMCRA permit that also requires approval, 
authorization, or certification under the Clean Water Act.
---------------------------------------------------------------------------

    \601\ 30 U.S.C. 1292(a).
---------------------------------------------------------------------------

Proposed Paragraph (b)
    Existing paragraph (b) requires that the permittee mark the buffer 
zone that is not to be disturbed. We propose to move this provision to 
30 CFR 816.11(e), which contains a similar requirement, to consolidate 
the marking requirement in the signs and markers section.
    Proposed paragraph (b) would establish requirements specific to 
mining through or diverting perennial or intermittent streams. Proposed 
paragraph (b)(1) would require compliance with the design and 
construction and maintenance plans approved in the permit. Proposed 
paragraph (b)(2) would require that the permittee restore the 
hydrological form and ecological function of the stream segment as 
expeditiously as practicable. In essence, this provision would require 
that the permittee take timely steps to restore the stream, first by 
constructing an appropriate channel as soon as surface mining is 
completed in the area in which the channel is to be located, then by 
planting appropriate vegetation in the riparian corridor in the first 
appropriate season following channel construction, followed by whatever 
other action may be needed to restore the stream's ecological function.
    Proposed paragraph (b)(2) does not mean that we anticipate rapid 
restoration of the ecological function of the stream. We recognize that 
a considerable amount of time may be needed to accomplish that 
requirement, particularly if restoration of the ecological function 
requires establishment of substantial canopy cover. Appendix B of a 
2012 EPA publication describes a scenario in which high-gradient stream 
channels devoid of aquatic life on an abandoned minesite in West 
Virginia may be restored to biological health in an estimated 10 
years.\602\ This time is roughly consistent with the time required for 
restoration of low-gradient streams in Illinois and Indiana, as 
discussed in Part II of this preamble. Other studies suggest that a 
much longer, as-yet-undetermined length of time may be needed to 
restore formerly high-quality Appalachian streams to a biological 
condition comparable to their premining biological condition.\603\ 
However, as discussed in connection with proposed paragraph (b)(2)(ii), 
re-establishment of the premining biological condition is not 
necessarily required to restore the ecological function of the stream.

---------------------------------------------------------------------------

    Proposed paragraph (b)(2)(i) would provide that a restored stream 
channel or a stream-channel diversion need not exactly replicate the 
channel morphology that existed before mining, but it must have a 
channel morphology comparable to the premining form of the affected 
stream segment in terms of baseline stream pattern, profile, and 
dimensions, including channel slope, sinuosity, water depth, bankfull 
depth, bankfull width, width of the flood-prone area, and dominant in-
stream substrate. These characteristics are critical to restoration of 
the premining hydrological form or the ecological function of the 
stream or both. The proposed paragraph also would use terminology that 
would improve consistency with corresponding requirements under section 
404 of the Clean Water Act. Finally, proposed paragraph (b)(2)(i) would 
include a clause specifying that, for degraded streams, the enhancement 
provisions of proposed paragraph (b)(4) would apply in place of the 
requirement in proposed paragraph (b)(2)(i) for restoration of streams 
to their premining form. This clause is necessary to ensure that the 
proposed rule would not require restoration of a degraded stream to its 
degraded premining form and condition.
    Proposed paragraph (b)(2)(ii)(A) would specify that a stream 
flowing through a restored stream channel or a stream-channel diversion 
must meet the functional restoration criteria established by the 
regulatory authority in consultation with the Clean Water Act agency 
under proposed 30 CFR 780.28(e)(1). Proposed paragraph (b)(2)(ii)(B) 
would clarify that a stream flowing through a restored stream channel 
or a stream-channel diversion need not contain precisely the same biota 
or have the same biological condition as the original stream segment 
did before mining, but it must have a biological condition that is 
adequate to support the uses that existed before mining and that would 
not preclude attainment of the designated uses of the original stream 
segment under section 101(a) or 303(c) of the Clean Water Act \604\ 
before mining. This provision is intended to allow some change in the 
species composition of the array of insects, fish, and other aquatic 
organisms found in a stream flowing through a restored stream channel 
or stream-channel diversion, provided that the change in species 
composition would preclude neither any use that existed before mining 
nor attainment of any designated use before mining.
---------------------------------------------------------------------------

    \604\ 33 U.S.C. 1251(a) and 1313(c).
---------------------------------------------------------------------------

    Proposed paragraph (b)(2)(ii)(C) would require that the biological 
condition of the restored stream be determined using a protocol that 
meets the requirements of proposed 30 CFR 780.19(e)(2). In effect, it 
would require use of a scientifically-valid multimetric bioassessment 
protocol used by agencies responsible for implementing the Clean Water 
Act, with modifications to meet SMCRA-related needs. At a minimum, the 
protocol must be based upon the measurement of an appropriate array of 
aquatic organisms, including benthic macroinvertebrates. It must 
require identification of benthic macroinvertebrates to the genus 
level; result in the calculation of index values for both habitat and 
macroinvertebrates; and provide a correlation of index values to the 
capability of the stream to support designated uses under section 
101(a) or 303(c) of the Clean Water Act, as well as any other existing 
or reasonably foreseeable uses. We seek comment on the effectiveness of 
using index scores from bioassessment protocols to ascertain impacts on 
existing, reasonably foreseeable, or designated uses. We also invite 
commenters to suggest other approaches that may be equally or more 
effective.
    Finally, proposed paragraph (b)(2)(ii)(D) would specify that 
populations of organisms used to determine the postmining biological 
condition of the stream segment must be self-sustaining within that 
segment. We

[[Page 44554]]

propose to include this provision because the presence of individual 
organisms that happen to drift into the reconstructed channel from 
other areas is not an indicator of restoration of the ecological 
function of the restored stream segment.
    Our proposed performance standards in paragraph (b) would 
complement our proposed permitting requirements at 30 CFR 780.12(b)(3) 
(one of the steps in the reclamation timetable is restoration of the 
form of perennial and intermittent stream segments), 780.12(b)(7) (one 
of the steps in the reclamation timetable is restoration of the 
ecological function of perennial and intermittent stream segments), 
780.12(h) (the reclamation plan must include a detailed stream 
restoration plan), 780.28(c) (detailed permit application requirements 
for mining through or diverting a perennial or intermittent stream 
segment), and 780.28(e)(2) (the regulatory authority must make a 
specific written finding before approving mining through or diversion 
of a perennial or intermittent stream segment).
    Proposed paragraph (b)(2)(iii)(A) would require that performance 
bond calculations for the operation include a specific line item for 
restoration of the ecological function of the stream segment. See also 
proposed 30 CFR 800.14(b)(2). In addition, proposed paragraph 
(b)(2)(iii)(B) would require that the permittee post a surety bond, a 
collateral bond, or a combination of surety and collateral bonds to 
cover the cost of restoration of the ecological function of the stream 
segment. A self-bond is not an appropriate mechanism to guarantee 
restoration of a stream's ecological function because of the risk that 
the company may cease to exist during the time required to accomplish 
that restoration. In addition, a self-bond does not require that the 
permittee file financial instruments or collateral with the regulatory 
authority, nor is there any third party obligated to complete the 
reclamation or pay the amount of the bond if the permittee defaults on 
reclamation obligations.
    Proposed paragraph (b)(2)(iii)(C) would require that the permittee 
demonstrate full restoration of the physical form of the restored 
stream segment before the site would qualify for final bond release 
under proposed 30 CFR 800.42(d). Proposed 30 CFR 800.42(b)(1) would 
define Phase I reclamation as including restoration of the form of 
perennial and intermittent streams, which means that no bond could be 
released until the permittee restores the hydrological form of any 
stream segment within the area to which the bond release application 
applies.
    Proposed paragraph (b)(2)(iii)(D) would require that the permittee 
demonstrate full restoration of the ecological function of the restored 
stream segment before the site would qualify for final bond release 
under proposed 30 CFR 800.42(d). Under proposed 30 CFR 800.42(b)(2) and 
(c)(2), the amount of bond retained following Phase I and II 
reclamation, respectively, must be sufficient to restore the ecological 
function of the stream segments that were restored in form as part of 
Phase I reclamation.
    Proposed paragraph (b)(3) would specify that, upon completion of 
construction of a stream-channel diversion or restored stream channel, 
the permittee must obtain a certification from a qualified registered 
professional engineer that the stream-channel diversion or restored 
stream channel meets all construction requirements of this section 
(except those pertaining to restoration of the ecological function) and 
is in accordance with the design approved in the permit. A similar 
requirement appears in existing 30 CFR 816.43(b)(4). We propose to move 
it to 30 CFR 816.57 to consolidate performance standards for the 
diversion and restoration of perennial and intermittent streams. We 
also propose to expand its scope to include restored stream channels 
because proper construction of those channels is no less important in 
terms of stability, hydraulic capacity, and ecological restoration than 
is construction of stream-channel diversions. This certification 
requirement applies only to the construction of the channel; it does 
not extend to restoration of ecological function or biological 
requirements, which may lie beyond the engineer's sphere of 
professional competence.
    Finally, proposed paragraph (b)(4) would provide that if the stream 
segment to be mined through or diverted is in a degraded condition 
before mining, the permittee must implement measures to enhance the 
form and ecological function of the segment as part of the restoration 
or diversion process. This provision is intended to ensure that stream 
segments degraded by prior mining or other human activities are 
improved to the fullest extent possible, not just restored to the 
condition that existed before the current mining operation. It also 
would implement section 515(b)(24) of SMCRA,\605\ which provides that 
surface coal mining and reclamation operations must ``achieve 
enhancement'' of fish, wildlife, and related environmental values where 
practicable, to the extent possible using the best technology currently 
available.
---------------------------------------------------------------------------

    \605\ 30 U.S.C. 1265(b)(24).
---------------------------------------------------------------------------

    Nothing in our proposed stream restoration requirements would 
exempt the permittee from meeting any additional onsite or offsite 
mitigation requirements that the U.S. Army Corps of Engineers may 
require under section 404 of the Clean Water Act.\606\

    We invite commenters to--
     Identify studies pertinent to restoration of the functions 
of perennial and intermittent streams, particularly headwaters streams, 
after mining or similar disturbances.
     Weigh in on whether our rule should differentiate between 
low-gradient and high-gradient streams on the theory that high-gradient 
streams are more difficult to restore in backfilled areas because of 
the lack of a competent substrate and the removal of perched aquifers.
Proposed Paragraph (c)
    Proposed paragraph (c)(1) would prohibit the use of perennial or 
intermittent streams as waste treatment systems to convey surface 
runoff from the disturbed area to a sedimentation pond. It also would 
prohibit construction of a sedimentation pond in a perennial or an 
intermittent stream. Almost all perennial and intermittent streams are 
of high value to fish and wildlife. Therefore, prohibiting the use of 
those streams for sedimentation control purposes is consistent with 
section 515(b)(24) of SMCRA,\607\ which provides that to the extent 
possible, surface coal mining and reclamation operations must use the 
best technology currently available to minimize disturbances to and 
adverse impacts on fish, wildlife, and related environmental values. 
Our experience indicates that there are almost always reasonable 
alternatives to using perennial and intermittent streams as waste 
treatment systems.
---------------------------------------------------------------------------

    \607\ 30 U.S.C. 1265(b)(24).
---------------------------------------------------------------------------

    However, in steep-slope areas, those alternatives may not have the 
least overall adverse impact on fish, wildlife, and related 
environmental values because of the extensive disturbance and 
excavation that would be needed to construct diversions and 
sedimentation ponds outside streams in that topography. Therefore, 
proposed paragraph (c)(2) would exempt excess spoil fills or coal mine 
waste disposal facilities in steep-slope areas from this prohibition 
when use of a perennial or intermittent stream segment as a waste 
treatment system for sediment control and construction of a 
sedimentation

[[Page 44555]]

pond in a perennial or an intermittent stream would have less overall 
adverse impact on fish, wildlife, and related environmental values than 
construction of diversions and sedimentation ponds on slopes above the 
stream.
    Proposed paragraph (c)(3) would require that the adverse impacts of 
using a stream segment as a waste treatment system on fish, wildlife, 
and related environmental values be minimized by keeping the length of 
the stream segment used as a waste treatment system as short as 
possible and, when practicable, maintaining an undisturbed buffer at 
least 100 feet in width along that segment. The proposed rule would 
require placement of the sedimentation pond as close to the toe of the 
excess spoil fill or coal mine waste disposal structure as possible. We 
also propose to require that the permittee remove the sedimentation 
pond and restore the hydrological form and ecological function of the 
stream segment in accordance with proposed paragraph (b)(2) following 
the completion of construction and revegetation of the fill or coal 
mine waste disposal structure.
    Both the 1979 and 1983 versions of our permanent regulatory program 
regulations prohibit the placement of sedimentation ponds in perennial 
streams unless approved by the regulatory authority. See 30 CFR 
816.46(a)(2) (1979) and 816.46(c)(1)(ii) (1983). However, the preamble 
to the 1979 rules explains that construction of sedimentation ponds in 
streams typically is a necessity in steep-slope mining conditions:

    Sedimentation ponds must be constructed prior to any disturbance 
of the area to be drained into the pond and as near as possible to 
the area to be disturbed. [Citation omitted.] Generally, such 
structures should be located out of perennial streams to facilitate 
the clearing, removal and abandonment of the pond. Further, locating 
ponds out of perennial streams avoids the potential that flooding 
will wash away the pond. However, under design conditions, ponds may 
be constructed in perennial streams without harm to public safety or 
the environment. Therefore, the final regulations authorize the 
regulatory authority to approve construction of ponds in perennial 
streams on a site-specific basis to take into account topographic 
factors.
* * * * *
    Commenters suggested allowing construction of sedimentation 
ponds in intermittent and perennial streams. Because of the 
physical, topographic, or geographical constraints in steep slope 
mining areas, the valley floor is often the only possible location 
for a sediment pond. Since the valleys are steep and quite narrow, 
dams must be high and must be continuous across the entire valley in 
order to secure the necessary storage.
* * * * *
    The Office recognizes that mining and other forms of 
construction are presently undertaken in very small perennial 
streams. Many Soil Conservation Service (SCS) [now the Natural 
Resources Conservation Service] structures are also located in 
perennial streams. Accordingly, OSM believes these cases require 
thorough examination. Therefore, the regulations have been modified 
to permit construction of sedimentation ponds in perennial streams 
only with approval by the regulatory authority.

44 FR 15159-15160 (Mar. 13, 1979) (citations omitted).
    In short, what was true in 1979 remains true today; i.e., 
sedimentation ponds must be constructed where there is sufficient 
storage capacity, which, in narrow valleys lacking natural terraces, 
typically means in the stream.
    Our proposed rule is consistent with a March 1, 2006, letter from 
Benjamin Grumbles, Assistant Administrator of the EPA, to John Paul 
Woodley, Assistant Secretary of the Army (Civil Works). Among other 
things, that letter states that the sedimentation pond must be 
constructed as close to the toe of the fill as practicable to minimize 
temporary adverse environmental impacts associated with construction 
and operation of the waste treatment system.
19. Section 816.71: How must I dispose of excess spoil?
    We propose to revise our excess spoil rules to minimize the extent 
to which excess spoil fills adversely impact perennial and intermittent 
streams, to improve fill stability, and to enhance fill aesthetics and 
compatibility with surrounding landforms. As previously discussed in 
the portions of this preamble concerning 30 CFR 780.35, we propose to 
move paragraphs (b)(1) (design certification), (c) (location), and 
(d)(1) (foundation investigations) of the existing version of 30 CFR 
816.71 to 30 CFR 780.35 as part of our effort to place provisions that 
are solely design considerations and requirements in our permitting 
regulations in subchapter G rather than in the performance standards in 
subchapter K.
Proposed Paragraph (a): General Requirements
    Both the existing and proposed versions of paragraph (a) require 
that excess spoil be placed in a controlled manner. However, we propose 
to revise the introductory language of this paragraph to specifically 
require that excess spoil be transported and placed by mechanical 
means. The added language is intended to more fully implement 
515(b)(22)(A) of SMCRA,\608\ which requires that excess spoil be 
``transported and placed in a controlled manner in position for 
concurrent compaction and in such a way to assure mass stability and to 
prevent mass movement.'' Our existing rules at 30 CFR 816.73 allow end-
dumping of excess spoil down steep slopes into a valley. This practice 
relies upon gravity transport, rather than mechanical transport, of 
spoil to its final location. We no longer consider gravity transport of 
spoil to its final location to be controlled placement under section 
515(b)(22)(A) of SMCRA.\609\ The preamble to our proposed removal of 30 
CFR 816.73 explains the shortcomings of end-dumping and durable rock 
fills in greater detail. However, nothing in the proposed revisions to 
our excess spoil requirements would prohibit the construction of valley 
fills, head-of-hollow fills, sidehill fills, or any type of fill other 
than durable rock fills.

---------------------------------------------------------------------------

    We propose to revise existing paragraphs (a)(1) through (3) and add 
paragraphs (a)(4) through (7) as follows:
     Proposed paragraph (a)(1) is substantively identical to 
existing paragraph (a)(1) except that we propose to add a requirement 
that excess spoil placement will minimize adverse effects of leachate 
and surface-water runoff on the biological condition of perennial and 
intermittent streams within the permit area, not just adverse effects 
on surface water and groundwater as in the existing rule. The new 
requirement would implement section 515(b)(24) of SMCRA \610\ more 
fully by minimizing adverse impacts of the operation on fish, wildlife, 
and related environmental values.
---------------------------------------------------------------------------

    \610\ 30 U.S.C. 1265(b)(24).
---------------------------------------------------------------------------

     Proposed paragraph (a)(2) is substantively identical to 
existing paragraph (a)(2).
     We propose to revise paragraph (a)(3) to be more 
consistent with the underlying requirement in section 515(b)(22)(G) of 
SMCRA,\611\ which provides that excess spoil must be placed in a manner 
that will ensure that ``the final configuration is compatible with the 
natural drainage pattern and surroundings and suitable for intended 
uses.'' As revised, proposed paragraph (a)(3) would require that the 
final surface configuration of the fill be suitable for revegetation 
and the postmining land use or uses and be compatible with the natural 
drainage pattern and surroundings. The existing

[[Page 44556]]

rule does not mention the final configuration of the fill or the 
natural drainage pattern. Our proposed revisions would correct those 
omissions.
---------------------------------------------------------------------------

    \611\ 30 U.S.C. 1265(b)(22)(G).

     Proposed paragraph (a)(4) would add a requirement that 
excess spoil be placed in a manner that would minimize disturbances to 
and adverse impacts on fish, wildlife, and related environmental values 
to the extent possible, using the best technology currently available. 
This provision parallels the language of section 515(b)(24) of 
SMCRA,\612\ which applies to all aspects of surface coal mining and 
reclamation operations, including the disposal of excess spoil.
---------------------------------------------------------------------------

    \612\ 30 U.S.C. 1265(b)(24).
---------------------------------------------------------------------------

     Proposed paragraph (a)(5) would require that excess spoil 
be placed in a manner that would ensure that the fill will not change 
the size or frequency of peak flows from precipitation events or thaws 
in a way that would result in an increase in damage from flooding when 
compared with the impacts of premining peak flows.
     Proposed paragraph (a)(6) would require that excess spoil 
be placed in a manner that would ensure that the fill will not preclude 
any existing or reasonably foreseeable use of surface water or 
groundwater or, for surface water downstream of the fill, preclude 
attainment of any designated use under section 101(a) or 303(c) of the 
Clean Water Act.\613\ The proposed language parallels the terminology 
in our proposed definition of ``material damage to the hydrologic 
balance outside the permit area'' in 30 CFR 701.5, which relies in 
large measure upon the status of existing, reasonably foreseeable, and 
designated uses of water.

    \613\ 33 U.S.C. 1251(a) and 1313(c), respectively.

     Proposed paragraph (a)(7) would require that excess spoil 
be placed in a manner that would ensure that the fill will not cause or 
contribute to an exceedance of any applicable federal, state, or tribal 
water quality standards.
    Proposed paragraphs (a)(5) through (7) would more fully implement 
sections 510(b)(3) and 515(b)(10) of SMCRA.\614\ Section 510(b)(3) 
\615\ prohibits approval of a permit application unless the applicant 
demonstrates and the regulatory authority finds that the proposed 
operation ``has been designed to prevent material damage to the 
hydrologic balance outside the permit area.'' Section 515(b)(10) \616\ 
requires that surface coal mining and reclamation operations be 
conducted so as to ``minimize disturbances to the prevailing hydrologic 
balance at the mine-site and in associated offsite areas and to the 
quality and quantity of water in surface and ground water systems both 
during and after surface coal mining operations and during 
reclamation.'' The proposed revisions also are consistent with our 
proposed definition of ``material damage to the hydrologic balance 
outside the permit area'' in 30 CFR 701.5, which focuses on mining-
related impacts to uses of groundwater and surface water.

Proposed Paragraph (b): Stability Requirements
    We propose to move existing paragraph (b))(1), which pertains to 
certification of the design for the excess spoil fill and appurtenant 
structures, to 30 CFR 780.35 as part of our effort to move permitting 
requirements from the performance standards of subchapter K to the 
permitting provisions of subchapter G. We propose to redesignate 
existing paragraph (b)(2) as paragraph (b)(1) and revise it to require 
that the fill not only be designed to attain a minimum static safety 
factor of 1.5 as required by the existing rules, but that the fill 
actually be constructed to attain that safety factor. This change is 
consistent with section 515(b)(22)(A) of the Act,\617\ which requires 
that all excess spoil be placed in a way that ensures mass stability 
and prevents mass movement.
---------------------------------------------------------------------------

    \617\ 30 U.S.C. 1265(b)(22)(A).
---------------------------------------------------------------------------

    We also propose to redesignate existing paragraph (d)(2), which 
requires keyway cuts for excess spoil fills built on steep slopes, as 
paragraph (b)(2). In addition, we propose to replace the term ``keyway 
cuts'' with ``bench cuts.'' The term ``keyway cut'' is technically a 
cut beneath a dam that is used to extend low-permeability fill material 
to, but not into, bedrock. The term ``bench cut'' is more appropriate 
here because it refers to cuts into bedrock, not just down to bedrock. 
Fill construction under steep-slope conditions requires that cuts be 
made into bedrock, not just down to bedrock, to ensure stability. 
Therefore, our proposed revisions would provide greater fill stability 
than the existing regulations.
Proposed Paragraph (c): Compliance With Permit
    We propose to move the fill location requirements of existing 
paragraph (c) to 30 CFR 780.35 because those requirements pertain 
primarily to the fill design and thus are more appropriately codified 
as part of the permitting provisions of subchapter G. We propose to 
replace those requirements with a performance standard reminding the 
permittee that the fill must be constructed in accordance with the 
design and plans approved in the permit. Proposed paragraph (c) would 
require that fills be built on the sites selected under section 780.35 
in a manner consistent with the designs submitted under those sections 
and approved as part of the permit.
Proposed Paragraph (d): Requirements for Handling of Organic Matter and 
Soil Materials
    We propose to move the foundation investigation requirements of 
existing paragraph (d)(1) to 30 CFR 780.35 to consolidate those 
provisions with a similar and overlapping foundation investigation 
requirement in that section. We also propose to redesignate existing 
paragraph (d)(2) as paragraph (b)(2) as discussed above.
    We propose to redesignate existing paragraph (e)(1) as new 
paragraph (d). Proposed paragraph (d) would require that soil and 
organic matter, including vegetative materials, in the footprint of 
excess spoil fills be salvaged, stored, and redistributed or otherwise 
used in a manner consistent with our proposed revisions to 30 CFR 
780.12(e) and 816.22.
Proposed Paragraph (e): Surface Runoff Control Requirements
    As discussed above, we propose to redesignate existing paragraph 
(e)(1) as new paragraph (d). In addition, we propose to redesignate 
existing paragraphs (e)(2) through (5) as paragraphs (g)(1), (h), (i), 
and (g)(3), respectively.
    We propose to redesignate existing 30 CFR 816.72(a) as 30 CFR 
816.71(e) and revise it to apply to all fills because control of 
surface-water runoff from the fill and adjacent areas is critical to 
the stability of all types of fills, not just valley and head-of-hollow 
fills. Proposed paragraph (e)(1), like existing 30 CFR 816.72(a), would 
require that runoff from areas above the fill and runoff from the 
surface of the fill be directed into stabilized channels designed to 
meet the requirements of 30 CFR 816.43 and to safely pass the runoff 
from a 100-year, 6-hour precipitation event. We do not consider surface 
runoff diversions constructed under proposed 30 CFR 816.71(e)(1) to be 
stream-channel diversions or restored streams, nor would they qualify 
as offsetting fish and wildlife enhancement measures under proposed 30 
CFR 780.28(d)(2).
    In proposed paragraph (e)(1)(ii), we propose to add a requirement 
that those

[[Page 44557]]

channels be designed using the appropriate regional NRCS synthetic 
storm distribution. The preamble to proposed 30 CFR 780.29 explains the 
rationale for this proposed requirement.
    Like its counterpart in existing 30 CFR 816.72(a), proposed 
paragraph (e)(2) would prohibit directing uncontrolled surface runoff 
over the outslope of the fill. Like the existing rule, it also would 
require that the permittee grade the top surface of a completed fill 
such that the final slope after settlement will be toward properly 
designed drainage channels.
Proposed Paragraph (f): Control of Water Within the Footprint of the 
Fill
    Our proposed revisions to this paragraph focus on underdrain 
requirements, with particular emphasis on ensuring the use of hard, 
weather-resistant materials and construction techniques that will 
promote long-term stability. We propose to require that the underdrain 
system be designed to carry the anticipated infiltration of water due 
to precipitation, snowmelt, and water from seeps and springs in the 
foundation of the disposal area away from the excess spoil fill. This 
requirement would minimize the phreatic level within the fill. We also 
propose to require that the underdrain system be protected from 
material piping, clogging, and contamination by an adequate filter 
system designed and constructed using current, prudent engineering 
practices to ensure the long-term functioning of the underdrain system. 
A long-term functioning filter using natural materials generally 
requires multiple lifts of material specifically sized, graded, and 
placed so that the overlying lift is progressively smaller in diameter. 
Geotextile material may be used for filter construction. Filter 
construction is vital to providing a long-term functioning underdrain.
    We propose to prohibit the use of perforated pipe as an alternative 
to hard, weather-resistant rock for two reasons. First, minor shifts 
within a fill mass can result in a broken and consequently 
dysfunctional pipe underdrain, but a rock underdrain of sufficient size 
is likely to be flexible enough to retain sufficient continuity to 
transport infiltrated water from the fill. Second, a pipe with small 
perforations and limited to a single flow-through orifice is more 
likely to clog than a porous rock underdrain with multiple alternative 
pathways for water transport.
    Future changes in local surface-water and groundwater hydrology may 
result in water infiltration into the fill in excess of what is 
anticipated. Therefore, we propose to allow the use of perforated pipe 
in an underdrain system only for the purpose of enhancing the 
capability of the underdrain to pass water in excess of the anticipated 
maximum infiltration. However, the rock underdrain must be capable of 
transporting the anticipated maximum water infiltration out of the fill 
independent of the presence of the perforated pipe. In addition, the 
perforated pipe must be made of materials that are not susceptible to 
corrosion (not just corrosion-resistant materials as in the existing 
rules) and sufficiently crush-resistant to withstand pressures at the 
depth at which the pipe will be buried.
    Finally, we propose to specify that only hard rock that is 
resistant to weathering, for example, well-cemented sandstone and 
massive limestone, and that is not acid-forming or toxic-forming may be 
used to construct durable rock underdrains. The proposed rule would 
require that the underdrain be free of both soil and fine-grained, 
clastic rocks such as siltstone, shale, mudstone, and claystone. All 
rock used to construct underdrains would have to meet the criteria in 
the following table:

----------------------------------------------------------------------------------------------------------------

    Section 515(b)(22) of SMCRA \618\ and most of the rules 
implementing that statutory provision focus on the long-term stability 
of excess spoil fills. Long-term stability is of great importance 
because the industry does not provide maintenance for fills following 
final bond release, nor does the regulatory authority monitor fills 
after final bond release. An effective underdrain system is a critical 
factor in ensuring fill stability.
---------------------------------------------------------------------------

    \618\ 30 U.S.C. 1265(b)(22).
---------------------------------------------------------------------------

    A functional underdrain system allows water from surface-water 
infiltration into the fill mass and from seeps and springs in the 
fill's foundation to freely pass from the fill. The absence of an 
effective underdrain can result in the formation of a phreatic surface 
and the associated potential for destabilization because of increased 
pore-water pressures within the fill mass. The effectiveness of an 
underdrain depends on whether the material is sufficiently permeable or 
hydraulically conductive to convey all subsurface water from the fill. 
This in turn depends on the presence of large and interconnected pores 
or voids between the material particles. For this reason, it is 
important that the underdrains be composed of large, blocky rock. For 
an underdrain to function well over the long term, the rock must be 
resistant to weathering and hard enough to withstand the effects of 
blasting and conveyance from the blast site to the site at which the 
underdrain system is being constructed. Rock that is not resistant to 
weathering effects, i.e., rock that is not ``sound,'' will disintegrate 
into fragments too small to act as an effective filter and consequently 
make the underdrain much less permeable.
    Historically, the criterion governing whether rock is suitable as 
underdrain material has been its ``durability.'' Existing 30 CFR 
816.71(f)(3) requires that the rock underdrains of excess spoil fills 
``be constructed of durable, nonacid-, nontoxic-forming rock (e.g., 
natural sand and gravel, sandstone, limestone, or other durable rock) 
that does not slake in water or degrade to soil material, and which is 
free of coal, clay or other nondurable material.'' Similar language 
appears in existing 30 CFR 816.73(b) for durable rock fills. The 
durable rock fill construction technique has been the predominant 
construction method for the last 30 years. Unlike other construction 
methods, it does not require underdrain construction prior to spoil 
placement or bottom-to-top spoil placement in thin lifts. Instead, 
spoil is end-dumped into valleys in a single lift or multiple lifts, 
during which gravity segregation theoretically forms a free-draining 
zone of large-sized rock in the lower one-third of the fill.
    The existing regulations do not specify how the durability of rock 
is to

[[Page 44558]]

be determined. In general, both the mining industry and regulatory 
authorities have relied upon the slake durability index (SDI) for this 
purpose. This test involves the placement of oven-dried rock samples in 
2 mm wire mesh drums 1/3 immersed in water, which are then rotated at 
20 rpm for 10 minutes for two cycles. The weight of the sample 
remaining in the drum is divided by the weight of the original sample 
and multiplied by 100 to obtain a percentage. SDI values of 90 percent 
or more are generally considered durable.
    OSMRE studies and inspection reports indicated that some of the 
rock material being used in durable rock fill construction was weak and 
non-durable despite documentation in the permit that the materials 
being used were considered durable based on SDI tests. The apparent 
failure of the SDI tests to adequately distinguish between durable and 
nondurable rock was attributed to the nature of the test and the 
behavior of shale and other mudstones as they slake or disintegrate 
into soil. Frequently, samples with those geologic compositions would 
turn into loose flakes or mud balls that would not pass through the 
wire mesh during the test. State and federal regulatory authorities 
have developed a broad consensus that the SDI test is not adequate for 
surface coal mining and excess spoil fill construction purposes.
    In response, we developed and tested an alternative testing 
protocol and classification system called the ``Strength Durability 
Classification'' (Welsh et al., 1991).\619\ The initial phase of the 
Strength Durability Classification protocol, the jar-slake test, 
consists of soaking oven-dried rock samples in water for 24 hours to 
identify very low-durability rock by its short-term slaking behavior. 
Samples with minimal breakdown are then subjected to a second phase of 
free-swell and point-load tests. The free-swell test entails measuring 
the swell of an oven-dried sample immersed in water for 4 hours. The 
degree of swell reflects the amount of water absorbed into the void 
spaces of the rock. Rocks that absorb more water generally weather more 
rapidly. The point-load strength test involves placing samples between 
opposite conical platens that are pressed or ``loaded'' against the 
sample until it fails. The amount of load needed to generate failure is 
the point-load strength of the sample. The test is performed on at 
least 20 samples for statistical validity. After plotting the point-
load strength and swell-test data on a graph, the points are compared 
to two ``zones'' on the same graph representing the acceptable value 
ranges for durable rock fill underdrains and more conventional, 
selectively placed rock underdrains. The Strength Durability 
Classification protocol has proven to be more discriminating than the 
SDI, but some critics claim that its durability standards are 
unrealistically stringent.

    In 2002, we conducted a study in which we visually estimated the 
percent of durable rock in 44 durable rock fills under construction and 
judged whether a discernible underdrain was forming by gravity 
segregation. Of 44 fills under construction, 28 appeared to have less 
than 80 percent durable rock and 5 fills showed no visual evidence of 
having a functioning underdrain. The study found that excess spoil 
fills in Appalachia generally have been stable, but it recommended 
improvement in the design, construction, and regulation of fills to 
ensure long-term stability. One recommendation urged continued work on 
the development of a more discriminating method for determining rock 
durability. The study suggested that the amount of sandstone available 
at a minesite should be one criterion for approving a proposed durable 
rock fill. It also stated that it might be feasible to develop a 
quantitative method of assessing gravity-segregated underdrain 
formation.\620\

    Given the problems with rock durability determination discussed 
above, application of the SDI or other tests of comparable rigor will 
not ensure a functioning underdrain in any type of fill. While the SDI 
can distinguish rocks that will quickly slake or disintegrate into soil 
material, it does not adequately assess whether they can withstand 
crushing or weakening from blasting and handling in a mine operation or 
resist the long-term effects of weathering. Although the Strength 
Durability Classification protocol is somewhat more discriminatory than 
the SDI, it also is not sufficiently representative of the short-term 
and long-term dynamics of a surface mine site. The jar-slake and free-
swell tests in particular do not adequately assess the long-term 
weathering resistance of the rock and the point-load test may not be 
sufficiently representative of the dynamic effects of blasting, 
collision, and abrasion.
    Although there are other classification systems relating to rock 
durability in the literature, many are designed for rocks unlike those 
encountered in coal mining. Other protocols apply only to shale, 
include SDI in addition to other tests or indices, or measure the 
properties of in-place rock slopes.
    Therefore, we propose to base the acceptability of rock for use in 
underdrains on the rock's hardness and resistance to weathering. 
Underdrains in a fill constructed in lifts occupy narrow corridors 
within the fill mass even when properly sized to handle anticipated 
maximum drainage discharge. Any clogging within these limited zones 
will quickly engender fill instability. Consequently, criteria for 
underdrain materials must be selected with the goal of ensuring that 
the underdrain system will remain effective on a long-term basis, not 
just until final bond release.
    Our proposed rule would establish criteria based on rock lithology 
and the results of two methods that measure the rock's hardness and 
soundness via laboratory tests. First, materials used to construct 
underdrains must consist of hard rock that is resistant to weathering, 
such as well-cemented sandstone and massive limestone, and that is not 
acid-forming or toxic-forming (and thus would not result in acid or 
toxic mine drainage). In addition, materials used to construct 
underdrains must be free of both soil and fine-grained, clastic rocks 
such as siltstone, shale, mudstone, and claystone, which generally are 
weaker and more prone to rapid weathering than sandstones and 
limestone. Fine-grained rocks also are problematic in that they produce 
a fine-grained, impermeable soil when highly weathered. From field 
observations of durable rock fills under construction, we know that the 
appearance of shale boulders can be deceptive. Large shale particles 
that appear competent soon after being end-dumped often quickly 
disintegrate from natural weathering processes, the stress resulting 
from being buried at depth, and abrasion

[[Page 44559]]

from handling. Even if tests find some shale to be hard and sound 
enough for underdrain material, the certifying engineer would have 
difficulty ensuring that all rock placed in the underdrain was 
correctly selected.
    Second, the materials must meet certain threshold criteria as 
determined by the Los Angeles abrasion test and either the sodium 
sulfate or magnesium sulfate soundness test.\622\ Highway departments 
frequently use both tests to assess the suitability of rock for the 
construction of roads and riprap-lined drainage channels. The Los 
Angeles abrasion test focuses on rock hardness. It consists of 
placement of the rock sample in a steel drum containing a prescribed 
number of steel spheres. After rotating the drum 1,000 times, the 
sample is removed and sieved. The amount of degradation of the sample 
is reported as the percent (by weight) of the sample lost through the 
sieve. The shocks, collisions, and abrasions that the sample 
experiences are reasonably representative of the dynamics and handling 
of materials at a minesite.
---------------------------------------------------------------------------

    \622\ See https://www.pavementinteractive.org/index.php?title=Sulfate_Soundness_Test (last accessed January 19, 
2015).
---------------------------------------------------------------------------

    The sodium sulfate and magnesium sulfate soundness tests measure 
the susceptibility of rock to weathering. In these tests, the rock 
sample is immersed in a saturated solution of sodium sulfate or 
magnesium sulfate, after which the sample is placed in an oven to 
dehydrate the salts, which precipitate in the voids between the rock 
particles. The process is then repeated on the sample for a specified 
number of cycles to simulate freezing and thawing. The external 
expansive force of the salt crystals during the immersion phase of each 
cycle simulates the expansion of water upon freezing. We acknowledge 
that freezing of water in rocks and soil does not occur in all 
climates. Furthermore, its occurrence is limited to a relatively 
shallow depth below the surface and consequently is not a process that 
would affect most of the buried underdrain. However, an underdrain is 
only as good as its weakest point and, like the natural weathering 
process, this test exploits openings and weaknesses in rock such as 
fractures and the porous zones of weakly cemented grains. The sulfate 
soundness tests measure the rock's ability to withstand repeated 
freeze-thaw cycles and thus facilitate identification of those rock 
materials most likely to remain competent on a long-term basis.
Proposed Paragraph (g): Placement of Excess Spoil
    Proposed paragraph (g)(1) is the counterpart to existing paragraph 
(e)(2). We propose to move the provision of existing paragraph (e)(2) 
requiring that the fill be covered with topsoil or other suitable 
materials to proposed paragraph (d), which contains all requirements 
related to soils. We also propose to eliminate the provision in 
existing paragraph (e)(2) that would allow the regulatory authority to 
approve an exception to the requirement that excess spoil be placed in 
horizontal lifts of no more than 4 feet in thickness. Placement in 
lifts exceeding 4 feet in thickness will not uniformly result in the 
concurrent compaction necessary to minimize the volume of void spaces 
in the fill. Minimization of the volume of void spaces is critical to 
minimizing the adverse impact on fish and wildlife because the volume 
of void spaces correlates directly with the amount of dissolved solids 
that migrate from the fill into the receiving stream. An increase in 
dissolved solids can have a substantial adverse impact on aquatic life.
    Proposed paragraph (g)(1) would require the use of mechanized 
equipment to transport and place excess spoil. Similarly, proposed 
paragraph (g)(2) would prohibit the use of any excess spoil transport 
and placement technique that involves end-dumping, wing-dumping, cast-
blasting, gravity placement, or casting spoil downslope, all of which 
are not conducive to concurrent compaction or placement in lifts no 
greater than 4 feet in thickness. As noted above, section 515(b)(22)(A) 
of SMCRA \623\ provides that all excess spoil material resulting from 
surface coal mining operations must be ``transported and placed in a 
controlled manner in position for concurrent compaction and in such a 
way to assure mass stability and to prevent mass movement.'' Our 
proposed prohibition on the placement of excess spoil in horizontal 
lifts greater than 4 feet in thickness would improve implementation of 
this provision of SMCRA, especially the requirements for controlled 
placement and concurrent compaction. As explained in our discussion of 
proposed paragraph (a), our existing rules at 30 CFR 816.73 allow end-
dumping of excess spoil down steep slopes into a valley. This practice 
relies upon gravity transport of spoil to its final location. We no 
longer consider gravity transport of spoil to its final location to be 
controlled placement under section 515(b)(22)(A) of SMCRA.\624\ Only 
mechanical transport meets that statutory requirement. The preamble to 
our proposed removal of 30 CFR 816.73 explains the shortcomings of end-
dumping and durable rock fills in greater detail.

---------------------------------------------------------------------------

    Furthermore, we have found that gravity placement in single or 
large lifts has resulted in elevated suspended solids during storm 
events because of the flushing of fine material from the loose-dumped 
excess spoil and from the typically large unvegetated active free face 
associated with this construction method. Placement in smaller lifts 
with concurrent compaction would decrease the permeability of the fill, 
inhibiting infiltration, allowing revegetation of the fill face 
concurrent with construction of the fill, and reducing discharges of 
both suspended and dissolved solids.
    Proposed paragraph (g)(3) is the counterpart to existing paragraph 
(e)(5). Proposed paragraph (g)(3)(i) would require that acid-forming 
and toxic-forming materials be handled and placed in accordance with 30 
CFR 816.38 and in a manner that will minimize adverse effects on plant 
growth and the approved postmining land use. Under proposed 30 CFR 
816.38(d), the only acceptable techniques for the placement of acid-
forming and toxic-forming materials would be isolation and treatment. 
The proposed rule would not authorize use of saturation techniques 
because of the stability risk that saturation poses for fills and 
because of the possibility that use of saturation techniques would 
increase discharges of total dissolved solids, which could have adverse 
impacts on aquatic life in streams that receive those discharges. 
Proposed paragraph (g)(3)(ii) would require that the permittee cover 
combustible materials with noncombustible materials in a manner that 
will prevent sustained combustion and minimize adverse effects on plant 
growth and the approved postmining land use.
    Proposed paragraph (g)(3) is consistent with section 515(b)(14) of 
SMCRA,\625\ which requires that all acid-forming materials and toxic 
materials be ``treated or buried and compacted or otherwise disposed of 
in a manner designed to prevent contamination of ground or surface 
waters'' and which requires that materials constituting a fire hazard 
be treated or buried to prevent sustained combustion. Section 
515(b)(22)(I) of SMCRA,\626\ which provides that excess spoil must be 
placed in a manner that meets ``all other

[[Page 44560]]

requirements of this Act,'' provides additional authorization for 
proposed paragraph (g)(3).

---------------------------------------------------------------------------

Proposed Paragraph (h): Final Configuration
    Proposed paragraph (h) is the counterpart to existing paragraph 
(e)(3), which requires that the final configuration of the fill be 
suitable for the approved postmining land use. Proposed paragraph 
(h)(1) would add requirements that the final configuration of the fill 
be compatible with the natural drainage pattern and the surrounding 
terrain and, to the extent practicable, consistent with natural 
landforms. The added provisions would better implement section 
515(b)(22)(G) of SMCRA,\627\ which requires that the final 
configuration be ``compatible with the natural drainage pattern and 
surroundings and suitable for intended uses.''
---------------------------------------------------------------------------

    \627\ 30 U.S.C. 1265(b)(22)(G).
---------------------------------------------------------------------------

    Proposed paragraph (h)(2) is substantively identical to the 
provisions of existing paragraph (e)(3) concerning terracing.
    Proposed paragraph (h)(3)(i) would add a new requirement for the 
use of geomorphic reclamation principles for the final surface 
configuration of the fill. Specifically, it would require that the top 
surface of the fill be graded to create a topography that includes 
ridgelines and valleys with varied hillslope configurations when 
practicable, compatible with stability and postmining land use 
considerations, and generally consistent with the premining topography. 
Geomorphic reclamation principles are intended to produce a final 
surface configuration with greater erosional stability and more 
ecological benefits than other techniques. Proposed paragraph 
(h)(3)(ii) would allow the final surface elevation of the fill to 
exceed the elevation of the surrounding terrain when necessary to 
minimize placement of excess spoil in perennial and intermittent 
streams, provided the final configuration complies with the 
compatibility and postmining land use requirements of proposed 
paragraphs (a)(3) and (h)(1).
    Sections 515(b)(10)(B)(i) and 515(b)(24) of SMCRA provide the 
primary statutory authority for proposed paragraphs (h)(3)(i) and (ii). 
Section 515(b)(10)(B)(i) of SMCRA \628\ requires that surface coal 
mining operations be conducted to prevent, to the extent possible using 
the best technology currently available, additional contributions of 
suspended solids to streamflow or runoff outside the permit area. 
Section 515(b)(24) of SMCRA \629\ requires that, to the extent possible 
using the best technology currently available, surface coal mining and 
reclamation operations be conducted so as to minimize disturbances and 
adverse impacts of the operation on fish, wildlife, and related 
environmental values and to achieve enhancement of those resources 
where practicable.

---------------------------------------------------------------------------

    Finally, we propose to add paragraph (h)(3)(iii), which would 
provide that the geomorphic reclamation requirements of paragraph 
(h)(3)(i) do not apply in situations in which they would result in 
burial of a greater length of perennial or intermittent streams than 
traditional fill design and construction techniques. Allowing use of 
reclamation techniques that would bury a greater length of stream than 
other techniques would not be consistent with section 515(b)(24) of 
SMCRA as discussed above.
Proposed Paragraph (i): Impoundments and Depressions
    Proposed paragraph (i) is the counterpart to existing paragraph 
(e)(4), which prohibits the construction of permanent impoundments on 
the completed fill and establishes criteria for the construction of 
small depressions on the surface of the fill. The proposed rule is 
substantively identical to the existing rule with the exception that we 
propose to further restrict the conditions under which small 
depressions may be constructed or retained on the completed fill. 
Specifically, we propose to allow small depressions only when they are 
consistent with the hydrologic reclamation plan approved in the permit 
in accordance with 30 CFR 780.22 and when infiltration resulting from 
those depressions would not result in elevated levels of parameters of 
concern (especially sulfate and other ions that increase specific 
conductance and electrical conductivity in streams) in discharges from 
the fill. The proposed revisions would assist in ensuring that 
discharges from the fill will not cause material damage to the 
hydrologic balance outside the permit area, in compliance with section 
510(b)(3) of SMCRA.\630\ It also would minimize ``disturbances to the 
prevailing hydrologic balance at the mine-site and in associated 
offsite areas and to the quality and quantity of water in surface and 
ground water systems'' as required by section 515(b)(10) of SMCRA.\631\

Proposed Paragraph (j): Surface Area Stabilization
    Proposed paragraph (j) is substantively identical to existing 
paragraph (g).
Proposed Paragraph (k): Inspections and Examinations
    Proposed paragraph (k) is the counterpart to existing paragraph 
(h), which establishes inspection requirements for excess spoil fills. 
We propose to revise the professional inspection requirements for 
excess spoil fills by specifying that the engineer or other specialist 
must conduct additional complete inspections during critical 
construction periods to ensure that the fill is constructed properly. 
Proposed paragraphs (k)(2)(i) and (ii) would require that the engineer 
or specialist conduct daily examinations during placement and 
compaction of fill materials and maintain a log of those examinations. 
Proposed paragraph (k)(3)(iii) would require that the certified report 
that the engineer or specialist submits for each complete inspection 
include a review and summary of the daily examination logs. If the 
report identifies any evidence of instability, structural weakness, or 
other hazardous conditions, proposed paragraph (k)(3)(ii) would require 
that the permittee submit an application for a permit revision that 
includes appropriate remedial design specifications. The proposed 
revisions are intended to ensure that excess spoil fills are 
constructed in compliance with the stability requirements of section 
515(b)(22) of SMCRA.\632\

    \632\ 30 U.S.C. 1265(b)(22).
---------------------------------------------------------------------------

    Placement of the underdrain and the placement of the filter are 
each considered critical construction phases. Therefore, two separate 
inspections are required if the underdrain is constructed first and the 
filter system is constructed later. However, these two phases can be 
concurrent, in which case one inspection may suffice for both phases. 
We invite comment on whether the rule should require additional 
specific oversight by the engineer when segregated, graded, natural 
material is used to construct the filter system.
    Finally, we propose to remove existing paragraph (h)(3)(ii), which 
pertains to durable rock fills constructed under 30 CFR 816.73, 
consistent with our proposal to prohibit that method of fill 
construction. The preamble concerning our proposed removal of 30 CFR 
816.73 explains our rationale for that proposed action.

[[Page 44561]]

Proposed Paragraph (l): Coal Mine Waste
    Proposed paragraph (l) would establish requirements for the 
disposal of coal mine waste in excess spoil fills. Proposed paragraph 
(l) is substantively identical to existing paragraph (i) except that we 
propose to add proposed paragraph (l)(1), which would allow disposal of 
coal mine waste in excess spoil fills only if the permittee 
demonstrates, and the regulatory authority finds in writing, that there 
is no credible evidence that the disposal of coal mine waste in the 
excess spoil fill will cause or contribute to a violation of applicable 
water quality standards or effluent limitations or result in material 
damage to the hydrologic balance outside the permit area. The proposed 
addition would assist in ensuring that the hydrologic balance 
protection requirements of sections 510(b)(3) and 515(b)(10) of SMCRA 
are met.\633\ In addition, we propose to add a cross-reference to 30 
CFR 816.81 to clarify that the coal mine waste must be placed in 
accordance with the general coal mine waste disposal requirements of 30 
CFR 816.81, not just the refuse pile requirements of 30 CFR 816.83.

Proposed Paragraph (m): Underground Disposal
    Proposed paragraph (m) is substantively identical to existing 
paragraph (j).
20. Why are we proposing to remove the provisions for rock-core chimney 
drains in existing 30 CFR 816.72(b)?
    We propose to remove existing 30 CFR 816.72(b) because mine 
operators are no longer constructing fills with rock-core chimney 
drains. A rock-core chimney drain is a vertical column of durable rock 
extending from the toe of the fill to the head of the fill and from the 
base of the fill to the surface of the fill. A few small fills 
constructed decades ago included rock-core chimney drains, but, to the 
best of our knowledge, the technique has not been used recently or on 
large fills.
    Our proposed removal of 30 CFR 816.72(b) would not prohibit the 
construction of head-of-hollow or valley fills without rock-core 
chimney drains. However, all proposed head-of-hollow and valley fills 
would have to meet the permitting requirements of proposed 30 CFR 
780.28 and 780.35. If approved, these fills would have to comply with 
the performance standards of proposed 30 CFR 816.71.
21. Why are we proposing to remove the provisions for durable rock 
fills in existing 30 CFR 816.73?
    Existing 30 CFR 816.73 allows excess spoil fills to be constructed 
by end-dumping, in which overburden is pushed or dumped over the side 
of the mountain to cascade into the valley below. In theory, the larger 
rocks roll to the bottom of the valley to form an underdrain by gravity 
segregation. We propose to remove this section for four reasons. First, 
further scrutiny of the statutory provisions governing disposal of 
excess spoil indicates that this method of fill construction does not 
comply fully with section 515(b)(22)(A) of SMCRA.\634\ That provision 
of SMCRA requires that surface coal mining and reclamation operations 
place all excess spoil material in such a manner that the ``spoil is 
transported and placed in a controlled manner in position for 
concurrent compaction and in such a way [as] to assure mass stability 
and to prevent mass movement.'' End-dumping of excess spoil relies upon 
gravity both for transport after dumping and to determine final 
placement, which does not comport well with the statutory requirement 
for transport and placement in a controlled manner.
---------------------------------------------------------------------------

    \634\ 30 U.S.C. 1265(b)(22)(A).
---------------------------------------------------------------------------

    Second, as discussed in the preamble to proposed 30 CFR 816.71(f), 
we have observed inconsistent formation of underdrains in durable rock 
fills. Non-functional underdrains may compromise the stability of the 
fill by raising the moisture content of the fill material, which 
increases the ability of that material to move. Saturated fills are 
prone to buckling and landslides.
    Third, as discussed in detail below, durable rock fills may 
increase the risk of flooding and associated damage because of the 
large size of the fill face and the length of time that the face 
remains unvegetated.
    Fourth, the lack of compaction during the construction of durable 
rock fills creates the potential for increased levels of total 
dissolved solids in discharges from those fills because of the greater 
amount of pore space and reactive surface compared with other types of 
fills. Higher levels of total dissolved solids in discharges from the 
fill translate to elevated electrical conductivity in streams 
downgradient of the fill. As summarized in Part II of this preamble, 
elevated electrical conductivity can adversely impact the capability of 
the stream to support certain species of benthic macroinvertebrates, 
which in turn reduces the capability of the stream to support species 
of fish dependent upon those macroinvertebrates as a food source.
    Therefore, we propose to refine our existing regulations by 
removing 30 CFR 816.73, which allows construction of durable rock fills 
by gravity transport and placement. With respect to other types of 
excess spoil fills, proposed 30 CFR 816.71(g) would require use of 
mechanized equipment to transport and place the excess spoil in lifts 
no greater than 4 feet, which would greatly increase both control and 
compaction. Increased compaction of the spoil placed in the fill would 
increase the density of each unit of excess spoil and thus decrease the 
amount of space that it occupies. The resulting reduction in the amount 
of spoil storage space needed would (or at least could) reduce the 
footprint of the fill, which should reduce the number and length of 
stream segments buried by the fill.
    Increased compaction also should reduce discharges of total 
dissolved solids and other parameters of concern, thus minimizing the 
adverse impacts on fish, wildlife, and related environmental values as 
required by section 515(b)(24) of the Act.\635\ Finally, construction 
of fills using mechanized methods of transport and placement would 
facilitate the special handling of acid-forming and toxic-forming 
materials, which should result in a reduction in the concentration and 
volume of toxic materials, such as selenium, in water discharged from 
the fill, which would further minimize adverse impacts on fish, 
wildlife, and related environmental values.

    As mentioned above, some durable rock fills have exacerbated 
flooding during and after precipitation events. Flooding may threaten 
public safety and cause property damage downstream of the fill. The 
following case studies describe how durable rock fills may contribute 
to flooding and damage from flooding.
Snap Creek, West Virginia
    On June 13, 2010, an area near the town of Man in Logan County, 
West Virginia, received approximately 4.8 inches of rain within 24 
hours. Flood-related damage occurred downstream from an end-dumped 
durable rock fill on the Snap Creek minesite (Permit S-5013-96) south 
of Man. Stormwater runoff flowing down the face of the fill completely 
filled the sedimentation pond near the toe of the fill. The sediment-
laden runoff then scoured the flood plain of the Left Fork of Rich 
Creek down to bedrock for a distance of

[[Page 44562]]

approximately 0.25 mile. The scoured material, along with spoil from 
the face of the fill, was deposited on the flood plain and along the 
stream channel for an additional 0.25 mile to its confluence with Rich 
Creek. Sedimentation continued along Rich Creek approximately 0.25 mile 
further to the stream's confluence with the Guyandotte River. No one 
was injured and little property damage occurred because most of the 
affected areas were uninhabited.
    The fill was being graded to its final configuration when the 
rainfall event occurred. The finer fractions of the soil exposed on the 
face of an end-dumped fill during final grading are very susceptible to 
erosion, particularly during heavy rainfall events. Protecting 
downstream areas from this type of mudflow at this stage of fill 
construction is nearly impossible, which provides additional 
justification for prohibiting the construction of durable rock fills.
Kayford South, West Virginia
    On June 13, 2010, a significant rainfall event occurred near the 
town of Dorothy in Raleigh County, West Virginia, resulting in 
flooding, erosion, and deposition of eroded mine spoil downstream from 
a durable rock fill associated with a surface mine (Permit S-3008-00). 
The event eroded the face of the fill, which was being graded for 
reclamation, with the sediment completely filling the sedimentation 
pond below the toe of the fill. After filling the pond, water and 
mobilized sediment flowed down Gardner Branch approximately 0.5 mile to 
the confluence with the Clear Fork of the Coal River. The flow scoured 
the stream channel and deposited sediment along the length of Gardner 
Branch. In this case, no one was injured and little property damage 
occurred because the affected areas were uninhabited.
    The fill was being graded to its final configuration when the 
rainfall event occurred. A primary issue at this site and other durable 
rock fills is the time lag between completion of excess spoil placement 
and final grading because of the top-down construction method. In this 
case, the lag was more than 2 years. During this time, the face of the 
fill was completely exposed and susceptible to erosion.
Lyburn, West Virginia
    On July 19, 2002, a flood event on Winding Shoals Branch in Lyburn, 
Logan County, West Virginia, destroyed ten residences and damaged 
vehicles and property. Stormwater runoff, rock, mud, and debris from a 
surface mine (Permit S-5023-93) flooded the narrow stream valley. The 
primary cause of the significant damage at Lyburn was the condition of 
the durable rock fill and its proximity to structures. At the time of 
the storm, the company was reclaiming this end-dumped fill. As is 
typical of an end-dumped durable rock fill during reclamation, soil and 
small rock particles on the face of the fill were exposed and highly 
susceptible to erosion.
    Our proposal to remove 30 CFR 816.73 and the authority that it 
provides to construct durable rock fills using end-dumping and gravity 
segregation is intended to prevent the recurrence of events like those 
discussed above. Fills constructed from the bottom up in accordance 
with 30 CFR 816.71 are much less susceptible to erosion and much less 
likely to contribute to flooding than are durable rock fills, which are 
constructed from the top down. The faces of fills constructed in 
accordance with 30 CFR 816.71 can be reclaimed and revegetated in 
stages, which reduces surface runoff and susceptibility to erosion, 
while the faces of durable rock fills cannot be reclaimed and 
revegetated until the fill is completed.
22. Section 816.74: What special requirements apply to the disposal of 
excess spoil on a preexisting bench?
    We propose to revise 30 CFR 816.74(a) to clarify that the term 
``preexisting bench'' applies only to features located on previously 
mined areas or on bond forfeiture sites. This term does not apply to 
benches created as part of an earlier phase of the mining operation 
that generated the excess spoil to be disposed of under this provision.
    We propose to revise 30 CFR 816.74(b) for consistency with our 
proposed changes to 30 CFR 780.12(e) and 816.22 concerning the removal, 
salvage, storage, and redistribution of soil and organic matter. We 
propose to revise 30 CFR 816.74(c) by adding a requirement that 
underdrains comply with proposed 30 CFR 816.71(f)(3). In addition, 
proposed 30 CFR 816.74(e)(2), which is the counterpart to existing 30 
CFR 816.74(d)(2), would require the use of all reasonably available 
spoil to eliminate all preexisting highwalls, consistent with the 
regulations governing backfilling and grading of previously mined areas 
under 30 CFR 816.106.
    Finally, we propose to remove the gravity-transport provisions in 
30 CFR 816.74(h) because this method of transporting spoil from one 
bench to another is not fully consistent with section 515(b)(22)(A) of 
SMCRA,\636\ which provides that all excess spoil material resulting 
from surface coal mining operations must be ``transported and placed in 
a controlled manner in position for concurrent compaction and in such a 
way to assure mass stability and to prevent mass movement.'' Gravity 
transport is not transport in a controlled manner.

23. Section 816.81: How must I dispose of coal mine waste?
Proposed Paragraph (a): General Requirements
    Proposed paragraph (a) is substantively identical to the first 
sentence of existing paragraph (a), except that we propose to add 
language requiring compliance with the refuse pile requirements of 30 
CFR 816.83 and the coal mine waste impounding structure requirements of 
30 CFR 816.84 when applicable.
Proposed Paragraph (b): Basic Performance Standards
    Proposed paragraph (b) would include the remaining provisions of 
existing paragraph (a). Proposed paragraph (b)(1) would revise existing 
paragraph (a)(1) to require that the coal mine waste disposal facility 
minimize adverse effects not only on the quality and quantity of 
surface water and groundwater as in the existing rule, but also on the 
biological condition of perennial and intermittent streams within the 
permit area to the extent possible, using the best technology currently 
available. Our proposed revisions are consistent with section 
515(b)(24) of SMCRA,\637\ which requires that, to the extent possible 
using the best technology currently available, surface coal mining and 
reclamation operations be conducted so as to minimize disturbances and 
adverse impacts of the operation on fish, wildlife, and related 
environmental values and to achieve enhancement of those resources 
where practicable.
---------------------------------------------------------------------------

    \637\ 30 U.S.C. 1265(b)(24).
---------------------------------------------------------------------------

    We propose to add paragraph (b)(6), which would require that the 
coal mine waste disposal facility not change the size or frequency of 
peak flows from precipitation events or thaws in a way that would 
result in increased damage from flooding when compared with the impacts 
of premining peak flows. We also propose to add paragraph (b)(7), which 
would require that the coal mine waste disposal facility not preclude 
any existing or reasonably foreseeable use of surface water or 
groundwater or, for surface wates downstream of the

[[Page 44563]]

facility, preclude attainment of any designated use under section 
101(a) or 303(c) of the Clean Water Act.\638\ The proposed language 
parallels the terminology in our proposed definition of ``material 
damage to the hydrologic balance outside the permit area'' in 30 CFR 
701.5, which relies in large measure upon the status of existing, 
reasonably foreseeable, and designated uses of water. In addition, we 
propose to add paragraph (b)(8), which would require that the coal mine 
waste disposal facility not cause or contribute to an exceedance of any 
applicable water quality standards. Finally, we propose to add 
paragraph (b)(9), which would require that the disposal facility not 
discharge acid or toxic mine drainage.
---------------------------------------------------------------------------

    \638\ 33 U.S.C. 1251(a) and 1313(c), respectively.
---------------------------------------------------------------------------

    The proposed addition of paragraphs (b)(6) through (9) is intended 
to improve implementation of sections 510(b)(3) and 515(b)(10) of 
SMCRA. Section 510(b)(3) \639\ prohibits approval of a permit 
application unless the applicant demonstrates and the regulatory 
authority finds that the proposed operation ``has been designed to 
prevent material damage to the hydrologic balance outside the permit 
area.'' Section 515(b)(10) \640\ requires that surface coal mining and 
reclamation operations be conducted so as to ``minimize disturbances to 
the prevailing hydrologic balance at the mine-site and in associated 
offsite areas and to the quality and quantity of water in surface and 
ground water systems both during and after surface coal mining 
operations and during reclamation.'' The proposed revisions also are 
consistent with our proposed definition of ``material damage to the 
hydrologic balance outside the permit area'' in 30 CFR 701.5, which 
focuses on mining-related impacts to uses of groundwater and surface 
water. Finally, the proposed revisions are consistent with section 
702(a) of SMCRA,\641\ which provides that nothing in SMCRA may be 
construed as superseding, amending, modifying, or repealing the Clean 
Water Act or state laws enacted pursuant to the Clean Water Act.

Proposed Paragraph (c): Coal Mine Waste From Outside the Permit Area
    Proposed paragraph (c) is substantively identical to existing 
paragraph (b).
Proposed Paragraph (d): Design and Construction Requirements
    Proposed paragraph (d) would include existing paragraph (c) in 
revised form. Proposed paragraph (d)((1)(i) would require that coal 
mine waste disposal facilities be constructed in accordance with 
current, prudent engineering practices and any criteria established by 
the regulatory authority. The existing regulations require that the 
design of the facility meet those requirements, but they do not address 
the construction process, which also is important in ensuring that the 
structure is stable and performs as intended.
    Proposed paragraph (d)(1)(ii) would require that, as part of the 
design certification, the engineer specifically certify that any 
existing and planned underground mine workings in the vicinity of the 
disposal facility will not adversely impact the stability of the 
structure. The Martin County Slurry Spill incident in Martin County, 
Kentucky on October 11, 2000, illustrates the magnitude of 
environmental damage that can result when impounded coal refuse slurry 
breaks through into adjacent underground mine workings that open to the 
surface. In this case, the mine openings discharged 306 million gallons 
of slurry into two tributaries of the Tug Fork River (Coldwater Fork 
and Wolf Creek). The slurry covered nearby residents' yards to a depth 
of as much as 5 feet, visibly polluted more than 100 miles of 
waterways, including the Big Sandy and Ohio Rivers, and devastated 
aquatic life in 70 miles of stream. Six public water intakes were 
adversely affected and alternative water supplies had to be arranged 
for 27,000 residents. Cleanup costs were approximately $59 
million.\642\

---------------------------------------------------------------------------

    Proposed paragraph (d)(1)(ii) is intended to ensure that each coal 
mine waste disposal facility is designed to prevent similar events. 
This design requirement would benefit the public, the environment, and 
mine operators by reducing the probability of breakthroughs into 
underground mine workings and the environmental and property damage and 
cleanup expenses that may result from those breakthroughs.
    Proposed paragraph (d)(1)(iii) would require that the coal mine 
waste disposal facility be constructed in accordance with the design 
and plans submitted under 30 CFR 780.25 and approved in the permit and 
that a qualified registered professional engineer experienced in the 
design and construction of similar earth and waste structures certify 
that the facility has been constructed in accordance with the approved 
design. Proposed paragraph (d)(1)(iii) would provide additional 
safeguards for protection of the environment, public health and safety, 
and property. Thus, it would better implement section 102(a) of 
SMCRA,\643\ which states that one of the purposes of SMCRA is to 
``establish a nationwide program to protect society and the environment 
from the adverse effects of surface coal mining operations.'' To the 
extent that proposed paragraph (d)(1)(iii) would improve stability, it 
also would improve implementation of section 515(b)(11) of SMCRA,\644\ 
which requires that all waste piles be stabilized in designated areas, 
and sections 515(b)(13) and 515(f) of SMCRA,\645\ which include 
provisions intended to ensure that coal mine waste impoundments are 
constructed in a manner that would protect public safety and public and 
private property. And the proposed revisions would be consistent with 
section 515(b)(23) of SMCRA,\646\ which requires surface coal mining 
and reclamation operations to ``meet such other criteria as are 
necessary to achieve reclamation in accordance with the purposes of 
this Act, taking into consideration the physical, climatological, and 
other characteristics of the site.''

Proposed Paragraph (e): Foundation Investigations
    Proposed paragraph (e) is substantively identical to existing 
paragraph (d), except that we propose to add language requiring that 
the analysis of foundation conditions for the coal mine waste disposal 
facility take into consideration the effect of any underground mine 
workings located in either the permit area or the adjacent area. The 
rationale for this proposed change is the same as the rationale for 
proposed paragraph (d), as discussed above.
Proposed Paragraph (f): Soil Handling Requirements
    Proposed paragraph (f) would require that vegetation, organic 
matter, and soil materials be salvaged, stored, and redistributed or 
otherwise handled in accordance with proposed 30 CFR

[[Page 44564]]

816.22. While 30 CFR 816.22 would apply in the absence of this rule, 
the addition of this paragraph would reaffirm the applicability of that 
rule to coal mine waste disposal facilities.
Proposed paragraphs (g) and (h): Emergency Procedures and Underground 
Disposal
    Proposed paragraphs (g) and (h) are substantively identical to 
existing paragraphs (e) and (f), respectively.
24. Section 816.83: What special performance standards apply to coal 
mine waste refuse piles?
    Proposed 30 CFR 816.83 is substantively identical to existing 30 
CFR 816.83 except as discussed below. We propose to revise paragraph 
(b), which includes existing paragraph (a), to specify that the refuse 
pile must be constructed with the diversions and underdrains included 
in the approved design.
    In proposed paragraph (b)(3), which corresponds to part of existing 
paragraph (a)(2), we propose to add a requirement that diversion 
channels be designed using the appropriate regional NRCS synthetic 
storm distribution to determine the peak flow from surface runoff from 
a 100-year, 6-hour precipitation event. The preamble to proposed 30 CFR 
780.29 explains the rationale for this proposed requirement.
    We propose to remove existing paragraph (c)(1) because it 
duplicates the soil handling requirements of proposed 30 CFR 816.81, 
which 30 CFR 816.83(a) cross-references.
    In proposed paragraph (d)(2), which corresponds to existing 
paragraph (c)(3), we propose to delete language in the existing rule 
that allows the creation and retention of small depressions on the 
completed refuse pile. Removal of this provision is justified because 
depressions promote infiltration and because discharges filtered 
through coal mine waste typically contain higher levels of total 
dissolved solids, metals, and other parameters of concern than 
discharges filtered through mine spoil. The proposed revision would 
improve implementation of sections 510(b)(3) and 515(b)(10) of 
SMCRA.\647\ Section 510(b)(3) \648\ prohibits approval of a permit 
application unless the applicant demonstrates and the regulatory 
authority finds that the proposed operation ``has been designed to 
prevent material damage to the hydrologic balance outside the permit 
area.'' Section 515(b)(10) \649\ requires that surface coal mining and 
reclamation operations be conducted so as to ``minimize disturbances to 
the prevailing hydrologic balance at the mine-site and in associated 
offsite areas and to the quality and quantity of water in surface and 
ground water systems both during and after surface coal mining 
operations and during reclamation.''

    \649\ 30 U.S.C. 1265(b)(10).
---------------------------------------------------------------------------

    In proposed paragraph (e), which corresponds to existing paragraph 
(d), we propose to delete the existing inspection standards and 
requirements and replace them with a cross-reference to the 
corresponding inspection and examination requirements for excess spoil 
fills that we propose to adopt as part of 30 CFR 816.71. Excess spoil 
fills and coal mine waste refuse piles are similar structures in terms 
of engineering needs and requirements. Therefore, they should have 
identical inspection and examination requirements.
25. Section 816.84: What special requirements apply to coal mine waste 
impounding structures?
    Proposed 30 CFR 816.84 is substantively identical to existing 30 
CFR 816.84 except as discussed below. Proposed paragraph (b), which is 
the counterpart to existing paragraph (a), would clarify that coal mine 
waste may not be used to construct impounding structures unless the use 
of coal mine waste will not result acid drainage or toxic seepage 
through the impounding structure. The existing rule only refers to acid 
seepage. Our proposed revision of the scope of this rule to include 
toxic seepage is appropriate because section 515(b)(10)(A) of SMCRA 
\650\ requires avoidance of ``acid or other toxic mine drainage.'' We 
also propose to replace the term ``acid seepage'' in the existing rule 
with ``acid drainage'' because that is the term that we define in 30 
CFR 701.5. However, we propose to use the term toxic seepage in 
recognition of the mechanism by which we anticipate that any toxic mine 
drainage might develop.
---------------------------------------------------------------------------

    \650\ 30 U.S.C. 1265(b)(10)(A).
---------------------------------------------------------------------------

    Proposed paragraph (e), which is the counterpart to existing 
paragraph (d), would specify that diversions must be both designed and 
constructed to meet the requirements of 30 CFR 816.43. The existing 
rule contains only the design requirement. The performance standards of 
30 CFR 816.43 apply to all diversions subject to regulation under SMCRA 
and our proposed revision would reiterate that principle. We also 
propose to specify that the diversions must be designed using the 
appropriate regional NRCS synthetic storm distribution to determine the 
peak flow from surface runoff from a 100-year, 6-hour precipitation 
event. The preamble to proposed 30 CFR 780.29 explains the rationale 
for this proposed requirement.
    Finally, we propose to move existing paragraph (e) to 30 CFR 
780.25(d) because it is a permitting requirement rather than a 
performance standard. Our goal is to move permitting requirements now 
located in the performance standards of subchapter K to the permitting 
provisions of subchapter G whenever feasible.
26. Section 816.95: How must I protect surface areas from wind and 
water erosion?
    We propose to revise 30 CFR 816.95(b) to replace the references to 
topsoil with references to soil and soil substitutes to be consistent 
with 30 CFR 780.12(e) and 816.22(c), which allow the use of topsoil and 
subsoil substitutes and supplements under certain conditions.
27. Section 816.97: How must I protect and enhance fish, wildlife, and 
related environmental values?
    Unless otherwise noted, our proposed substantive revisions to 30 
CFR 816.97, as discussed below, are intended to more fully implement 
section 515(b)(24) of SMCRA,\651\ which provides that ``to the extent 
possible using the best technology currently available'' surface coal 
mining and reclamation operations must be conducted so as to ``minimize 
disturbances and adverse impacts of the operation on fish, wildlife, 
and related environmental values, and achieve enhancement of such 
resources where practicable.'' A few of the proposed revisions also 
would provide more detail on the measures and procedures needed to 
ensure compliance with the Endangered Species Act. Proposed 
requirements for the use of native species and reforestation would more 
completely implement section 515(b)(19) of SMCRA,\652\ which requires 
establishment of a ``permanent vegetative cover of the same seasonal 
variety native to the area of land to be affected and capable of self-
regeneration and plant succession.''

Proposed Paragraph (a): General Requirements
    Proposed paragraph (a) would require that the permittee, to the 
extent possible using the best technology currently available, minimize 
disturbances and adverse impacts on fish, wildlife, and related 
environmental values and

[[Page 44565]]

achieve enhancement of those resources where practicable, as described 
in detail in the fish and wildlife protection and enhancement plan 
approved in the permit in accordance with 30 CFR 780.16. Proposed 
paragraph (a) is substantively identical to both section 515(b)(24) of 
SMCRA \653\ and to existing paragraph (a), with the exception that we 
propose to add a reminder that the permittee must comply with the fish 
and wildlife protection and enhancement plan approved in the permit.

    \653\ 30 U.S.C. 1265(b)(24).
---------------------------------------------------------------------------

Proposed Paragraph (b): Species Listed or Proposed for Listing as 
Threatened or Endangered
    Existing 30 CFR 816.97(b) and (d) contain provisions that pertain 
to threatened and endangered species. We propose to consolidate those 
provisions in proposed paragraph (b). Proposed paragraph (b)(1) would 
set forth requirements concerning species that the U.S. Fish and 
Wildlife Service has listed or proposed for listing under the 
Endangered Species Act.
    Proposed paragraphs (b)(1)(i) through (iii) are substantively 
identical to the requirements of existing 30 CFR 816.97(b) with respect 
to federally-listed species, with four exceptions. First, we propose to 
replace the terms ``consult'' and ``consultation'' in the existing 
regulations with ``contact and coordinate'' and ``in coordination 
with'' to clarify that, in this context, these regulations do not refer 
to consultation under section 7(a)(2) of the Endangered Species Act.
    Second, we propose to expand the scope of paragraph (b)(1)(i) to 
include species proposed for listing as threatened or endangered under 
the Endangered Species Act, not just species actually listed under that 
law. We are proposing this change in response to discussions with the 
U.S. Fish and Wildlife Service. The proposed change is consistent with 
section 7(a)(4) of the Endangered Species Act, which provides that 
``[e]ach Federal agency shall confer with the Secretary on any agency 
action which is likely to jeopardize the continued existence of any 
species proposed to be listed under section 4 or result in the 
destruction or adverse modification of critical habitat proposed to be 
designated for such species.'' It also would assist in implementing the 
fish and wildlife protection provisions of sections 515(b)(24) and 
516(b)(11) of SMCRA. The conferencing requirement of section 7(a)(4) of 
the Endangered Species Act is not the same as the consultation 
requirement for threatened and endangered species under section 7(a)(2) 
of the Endangered Species Act.
    Third, in proposed paragraph (b)(1)(ii), we propose to add a 
sentence clarifying that the requirement that the permittee report to 
the regulatory authority the presence of any federally-listed 
threatened or endangered species within the permit area applies 
regardless of whether the species was listed before or after permit 
issuance. We also propose to expand this notification requirement to 
apply to both the permit area and the adjacent area, not just the 
permit area as under the existing rule. We are proposing this change in 
response to discussions with the U.S. Fish and Wildlife Service 
concerning compliance with the Endangered Species Act.
    We are considering whether to limit the notification requirement of 
proposed paragraph (b)(1)(ii) to the active mining phase of the 
operation; i.e., whether the final rule should specify that the 
notification requirement expires at the time of Phase II bond release 
because of the typical lack of activity on the site after that stage of 
reclamation. We invite comment on this question.
    Fourth, in proposed paragraph (b)(1)(iii)(A), we propose to add a 
requirement that the regulatory authority issue a permit revision order 
under 30 CFR 774.10(b) when necessary to implement the results of the 
coordination process with state and federal fish and wildlife agencies 
following receipt of notification under proposed paragraphs (b)(1)(ii) 
and (iii). This requirement would apply only when revision of the 
operation and reclamation plan approved in the permit is necessary to 
ensure protection of federally-listed threatened and endangered 
species.
    Proposed paragraph (b)(1)(iv) would expressly require compliance 
with any species-specific protective measures required by the 
regulatory authority in coordination with the U.S. Fish and Wildlife 
Service. While proposed paragraph (b)(1)(iv) would be a new regulation, 
the requirement itself is a longstanding component of the result of a 
formal section 7(a)(2) consultation under the Endangered Species Act 
with respect to the continuation and approval of surface coal mining 
and reclamation operations under a SMCRA regulatory program.
    Proposed paragraph (b)(1)(v) is substantively identical to those 
elements of existing paragraph (d) that pertain to the Endangered 
Species Act; i.e., it would provide that nothing in our regulations 
authorizes the taking of a threatened or endangered species in 
violation of the Endangered Species Act. Only the U.S. Fish and 
Wildlife Service may quantify allowable take of species listed as 
threatened or endangered.
    Proposed paragraph (b)(2) would set forth requirements pertaining 
to species listed as threatened or endangered under state statutes 
similar to the Endangered Species Act. It would include reporting and 
related requirements analogous to those of proposed paragraphs 
(b)(1)(ii) and (iii).
Proposed Paragraph (c): Bald and Golden Eagles
    Existing paragraphs (c) and (d) both contain provisions that 
pertain to bald and golden eagles. We propose to consolidate those 
provisions in proposed paragraph (c). Proposed paragraphs (c)(1) 
through (3) are substantively identical to existing paragraph (c). 
Proposed paragraph (c)(4) would consist of those elements of existing 
paragraph (d) that pertain to the Bald and Golden Eagle Protection Act; 
i.e., it would provide that nothing in our regulations authorizes the 
taking of a bald or golden eagle, its nest, or its eggs in violation of 
the Bald and Golden Eagle Protection Act.
Proposed Paragraph (d): Miscellaneous Protective Measures for Other 
Species of Fish and Wildlife
    We propose to redesignate existing paragraph (e), which contains 
miscellaneous provisions relating to protection of fish and wildlife in 
general, as paragraph (d). Proposed paragraph (d)(1) is substantively 
identical to existing paragraph (e)(1) with one exception. We propose 
to remove the clause allowing the regulatory authority to determine 
that is unnecessary to ensure that electric power transmission lines 
and other transmission facilities used for, or incidental to, surface 
mining activities on the permit area are designed and constructed to 
minimize electrocution hazards to raptors. We are not aware of any 
situations in which these precautions are not necessary or appropriate. 
We also propose to expand the scope of this paragraph to include all 
avian species with large wingspans, not just raptors, consistent with 
recommendations of the Avian Power Line Interaction Committee in a 2006 
publication,\654\ which found that non-raptor avian species with large 
wingspans including, but not limited to,

[[Page 44566]]

ravens, magpies, storks, and cranes, are subject to electrocution by 
power lines.

    Proposed paragraph (d)(2) would require that the permittee locate, 
construct, operate, and maintain haul and access roads and 
sedimentation control structures in a manner that avoids or minimizes 
impacts on important fish and wildlife species or other species 
protected by state or federal law. It is substantively identical to 
existing paragraph (e)(2), except that we propose to add the words

of section 515(b)(17) of SMCRA,\655\ which requires that surface coal 
mining and reclamation operations be conducted so as to ``insure that 
the construction, maintenance, and postmining conditions of access 
roads into and across the site of operations will control or prevent 
erosion and siltation, pollution of water, damage to fish or wildlife 
or their habitat, or public or private property.'' We also propose to 
apply the requirements of proposed paragraph (d)(2) to sedimentation 
control structures to more effectively implement the fish and wildlife 
protection requirements of section 515(b)(24) of SMCRA.\656\

    Proposed paragraph (d)(5) would require that the permittee reclaim 
and reforest lands that were forested at the time of application and 
lands that would revert to forest under conditions of natural 
succession in a manner that enhances recovery of the native forest 
ecosystem as expeditiously as practicable. This provision would assist 
in implementation of the fish and wildlife protection provisions of

section 515(b)(19) of SMCRA.\658\

Proposed Paragraph (e): Wetlands and Habitat of Unusually High Value 
for Fish and Wildlife
    We propose to redesignate existing paragraph (f), which pertains to 
wetlands, vegetation along rivers and streams and bordering ponds and 
lakes, and habitat of unusually high value for fish and wildlife, as 
paragraph (e) and revise it for clarity and to be consistent with 
section 515(b)(24) of SMCRA.\659\ The existing rule allows the 
permittee to select one of four options with respect to wetlands, 
vegetation bordering streams and water bodies, and habitat of unusually 
high value for fish and wildlife: (1) Avoid disturbances to them, (2) 
enhance them where practical, (3) restore them, or (4) replace them. 
Hence, the existing rule is not fully consistent with section 
515(b)(24) of SMCRA, which requires both minimization of disturbances 
and adverse impacts on fish, wildlife, and related environmental values 
to the extent possible and enhancement of those resources where 
practicable. Proposed paragraph (e) would improve consistency with 
section 515(b)(24) of SMCRA by requiring the permittee to enhance those 
resources where practical in all cases and by adding the qualifier ``to 
the extent possible'' with respect to the requirement to avoid 
disturbances to and restore or replace those resources. In accordance 
with accepted scientific terminology, we also propose to use the term 
``lentic'' to refer to vegetation bordering lakes and ponds. As 
proposed, paragraph (e) would require the permittee to avoid 
disturbances to, restore or replace, and, where practicable, enhance, 
wetlands, riparian vegetation along rivers and streams, lentic 
vegetation bordering ponds and lakes, and habitat of unusually high 
value for fish and wildlife.

Proposed Paragraph (f): Vegetation Requirements for Fish and Wildlife 
Habitat Postmining Land Use
    We propose to redesignate existing paragraph (g) as paragraph (f) 
and revise it by removing the requirement that plants used to 
revegetate areas with a fish and wildlife habitat postmining land use 
be arranged to maximize edge effect. Maximizing edge effect means that 
plantings would be designed to include the greatest amount of boundary 
areas between different types of natural habitats. It promotes the 
greatest species diversity, but also results in habitat fragmentation, 
which has deleterious effects on wildlife species that require large 
blocks of continuous habitat. We propose to replace that requirement 
with a provision that would require that the permittee select and 
arrange plant species to maximize the benefits to fish and wildlife. 
This change reflects current wildlife management philosophy, which 
emphasizes preservation or restoration of entire natural communities, 
rather than just those species that would benefit from the creation of 
edge effect.
    In addition, we propose to require the use of native species, 
prohibit the use of invasive plant species that are known to inhibit 
natural succession, and add a requirement that plant species be 
selected on the basis of their ability to sustain natural succession by 
allowing the establishment and spread of plant species across 
ecological gradients. These changes would improve implementation of 
section 515(b)(19) of SMCRA,\660\ which requires establishment of a 
``permanent vegetative cover of the same seasonal variety native to the 
area of land to be affected and capable of self-regeneration and plant 
succession.'' Section 515(b)(19) \661\ also provides that ``introduced 
species may be used * * * where desirable and necessary to achieve the 
approved postmining land use plan.'' We cannot envision any scenario in 
which introduced species would be either desirable or necessary to 
achieve a fish and wildlife habitat postmining land use.

Proposed Paragraph (g): Vegetation Requirements for Cropland Postmining 
Land Use
    We propose to redesignate existing paragraph (h) as paragraph (g). 
Both paragraphs are substantively identical, but we propose to remove 
the phrase ``throughout the harvested area'' from the existing rule. 
That phrase is both unclear and unnecessary.
Proposed Paragraph (h): Vegetation Requirements for Forestry Postmining 
Land Uses
    Proposed paragraph (h) would provide that any lands with either a 
managed or unmanaged forestry postmining land use must be replanted 
with native tree and understory species to the extent that doing so is 
not inconsistent with the type of forestry to be practiced as part of 
the postmining land use. This new paragraph also would require that 
plantings of commercial species be interspersed with plantings with 
native trees and shrubs of high value to wildlife, regardless of the 
type of forestry postmining land use. Proposed paragraph (h) would 
improve implementation of the revegetation requirements of section 
515(b)(19) of SMCRA \662\ and the provisions of section 515(b)(24) of 
SMCRA \663\ concerning protection and enhancement of fish, wildlife, 
and related environmental values, as previously discussed.

Proposed Paragraph (i): Vegetation Requirements for Other Postmining 
Land Uses
    We propose to revise existing paragraph (i) to add commercial and

[[Page 44567]]

intensive recreational uses to the list of postmining land uses for 
which the permittee must establish greenbelts to provide food and cover 
to wildlife. The uses that we propose to add are similar in intensity 
to the uses in the existing rule; therefore, the same requirements 
should apply. Proposed paragraph (i)(1) would require that the plants 
used to create the greenbelts be native and non-invasive, consistent 
with section 515(b)(19) of SMCRA \664\ and the purpose of the 
greenbelts. In addition, proposed paragraph (i)(1) would create an 
exception to the greenbelt requirement when greenbelts would be 
inconsistent with the approved postmining land use for that site.
---------------------------------------------------------------------------

    \664\ 30 U.S.C. 1265(b)(19).
---------------------------------------------------------------------------

    Proposed paragraph (i)(2) would add another requirement for lands 
with the postmining land uses listed in the introductory text of 
proposed paragraph (i). Specifically, proposed paragraph (i)(2)(i) 
would require the establishment of a 100-foot buffer \665\ comprised of 
native species, including species adapted to and suitable for planting 
in riparian zones, along each bank of all perennial and intermittent 
streams within the portion of the permit area for which these 
postmining land uses are approved. The species planted must consist of 
native tree and understory species if the land was forested at the time 
of application or if it would revert to forest under conditions of 
natural succession. The proposed requirements would improve 
implementation of the revegetation requirements of section 515(b)(19) 
of SMCRA \666\ and the provisions of section 515(b)(24) of SMCRA \667\ 
concerning protection and enhancement of fish, wildlife, and related 
environmental values, as previously discussed. Proposed paragraph 
(i)(2)(i) would provide an exception from the riparian buffer 
requirement when such a buffer would be incompatible with an approved 
postmining land use that is implemented during the revegetation 
responsibility period before final bond release under proposed Sec.  
800.42(d).

Proposed Paragraph (j): Planting Arrangement Requirements
    Proposed paragraph (j) would require that plantings on all 
reclaimed areas be designed and arranged in a manner that will optimize 
benefits to wildlife to the extent practicable and consistent with the 
approved postmining land use. The proposed requirement would improve 
implementation of the provisions of section 515(b)(24) of SMCRA \668\ 
concerning protection and enhancement of fish, wildlife, and related 
environmental values.

28. Section 816.99: What measures must I take to prevent and remediate 
landslides?
    We propose to revise this section to improve adherence to plain 
language principles and to delete the reference to erosion in existing 
30 CFR 816.99(a). The proposed deletion is appropriate because 
retention of an undisturbed natural barrier at the elevation of the 
lowest coal seam to be mined would not and could not play a role in 
preventing erosion on the disturbed area above the barrier. The role of 
such a barrier is limited to stability and preventing landslides.
29. Section 816.100: What are the standards for keeping reclamation 
contemporaneous with mining?
    We propose to revise this section to improve adherence to plain 
language principles and to add stream restoration to the list of 
reclamation activities that are subject to the contemporaneous 
reclamation requirement. Existing 30 CFR 816.100 states that 
reclamation activities include, but are not limited to, those 
specifically listed in the rule. Therefore, we consider our proposed 
addition of stream restoration to the list of activities to be a 
clarification of the existing regulation.
30. Why are we proposing to remove existing 30 CFR 816.101?
    As adopted on December 17, 1991, 30 CFR 816.101 established time 
and distance requirements for rough backfilling and grading following 
coal removal. However, we subsequently suspended this section, 
effective August 31, 1992, as a result of a Joint Stipulation of 
Dismissal in litigation following the issuance of that rule. See 57 FR 
33874, 33875 (Jul. 31, 1992) and Nat'l Coal Ass'n et al. v. U.S. Dep't 
of the Interior, et al., Civ. No. 92-0408-CRR (D.D.C.). We now propose 
to lift the suspension and remove this section as part of our rewrite 
of the backfilling and grading requirements. Removal of a section that 
has not been in effect for almost 20 years would improve the clarity of 
our requirements and avoid the confusion that can result on the part of 
persons who are not aware of the suspension.
    The contemporaneous reclamation requirements of 30 CFR 816.100, in 
combination with the site-specific reclamation timetable approved in 
the permit, should be sufficient to ensure that permittees complete 
rough backfilling and grading in a timely manner. The reclamation 
timetable requirement currently appears in existing 30 CFR 
780.18(b)(3), which we propose to redesignate as 30 CFR 780.12(b). 
Proposed 30 CFR 780.12(b) also would require that the reclamation 
timetable include application for each phase of bond release under 
proposed 30 CFR 800.42 because reclamation cannot be considered 
complete until the regulatory authority releases all bond posted for 
the site in accordance with proposed 30 CFR 800.42(d).
31. Section 816.102: How must I backfill the mined area and configure 
the land surface?
    We propose to revise and restructure this section to clarify 
exactly when and where our approximate original contour restoration 
requirements apply, consistent with our proposed revisions to the 
definition of approximate original contour in 30 CFR 701.5 and other 
statutory and regulatory requirements. Section 515(b)(3) of SMCRA \669\ 
provides the primary statutory basis for both the existing rules and 
the changes that we are proposing. In relevant part, section 515(b)(3) 
requires that surface coal mining and reclamation operations ``compact 
(where advisable to insure stability or to prevent leaching of toxic 
materials), and grade in order to restore the approximate original 
contour of the land with all highwalls, spoil piles, and depressions 
eliminated (unless small depressions are needed in order to retain 
moisture to assist revegetation or as otherwise authorized pursuant to 
this Act).'' It also provides exceptions to this requirement for 
mountaintop removal mining operations and thin and thick overburden 
situations.
---------------------------------------------------------------------------

    \669\ 30 U.S.C. 1265(b)(3).
---------------------------------------------------------------------------

Proposed Paragraph (a)
    We propose to revise the introductory language of paragraph (a) to 
clarify that the backfilling requirement applies only to mined areas, 
while the grading requirement applies to the entire disturbed area. The 
existing rule applies the backfilling requirement to the entire 
disturbed area. However, those portions of the disturbed area outside 
the mined area do not contain a pit or similar excavation that requires 
backfilling. (See the preamble discussion of our proposed definition of 
backfill in 30 CFR 701.5.) Those areas only require grading to restore 
the approximate original contour in compliance with

[[Page 44568]]

section 515(b)(3) of SMCRA.\670\ We also propose to require that the 
backfilling and grading of the minesite adhere to the plan approved in 
the permit in accordance with 30 CFR 780.12(d).
---------------------------------------------------------------------------

---------------------------------------------------------------------------

    Proposed paragraphs (a)(1)(i) through (ix) list exceptions from the 
requirement to restore the approximate original contour as the final 
surface configuration of the backfilled and regraded area. The 
exceptions in proposed paragraphs (a)(1)(i) through (v) correspond to 
the exceptions that appear in existing paragraph (k) and are 
substantively identical to those exceptions. We propose to reword the 
exception in proposed paragraph (a)(1)(v) to emphasize that the 
exception for remining operations applies only to the extent specified 
in 30 CFR 816.106(b); i.e., it is limited to an exception from the 
highwall elimination requirement. This proposed revision would not 
change existing law, policy, or practice, but it would add clarity 
concerning the scope of the exception.
    Proposed paragraphs (a)(1)(vi) and (vii) would clarify that excess 
spoil fills constructed in accordance with 30 CFR 816.71 or 816.74 and 
refuse piles constructed in accordance with 30 CFR 816.83 do not need 
to comply with approximate original contour restoration requirements. 
The rationale for these two exceptions appears in the preamble 
discussion of our proposed revisions to the definition of approximate 
original contour in 30 CFR 701.5.
    Proposed paragraph (a)(1)(viii) would clarify that permanent 
impoundments that meet the requirements of proposed paragraph 
(a)(3)(ii) and proposed Sec.  780.35(b)(4) are exempt from compliance 
with approximate original contour restoration requirements. The 
proposed exception is consistent with the definition of approximate 
original contour in section 701(2) of SMCRA,\671\ which contains a 
clause specifying that ``water impoundments may be permitted'' if they 
comply with the permanent impoundment provisions of section 515(b)(8) 
of SMCRA.\672\ The regulations implementing section 515(b)(8) of SMCRA 
are located at 30 CFR 816.49(b). Proposed 30 CFR 816.102(a)(3)(ii) 
would require compliance with 30 CFR 816.49(b). Approval of a permanent 
impoundment would not exempt the permittee from complying with all 
applicable approximate original contour restoration requirements on the 
remainder of the disturbed area.

    Proposed paragraph (a)(1)(ix) would allow the placement of 
overburden that otherwise would be classified as excess spoil on the 
mined-out area to heights in excess of the premining elevation when 
necessary to avoid or minimize construction of excess spoil fills on 
undisturbed land, provided that the placement occurs in accordance with 
proposed 30 CFR 780.35(b)(3). This provision would harmonize the 
approximate original contour restoration requirement of section 
515(b)(3) of SMCRA \673\ with section 515(b)(24) of SMCRA,\674\ which 
requires that surface coal mining and reclamation operations use the 
best technology currently available to ``minimize disturbances and 
adverse impacts of the operation on fish, wildlife, and related 
environmental values'' to the extent possible. Streams are generally 
recognized as among the habitats with the highest value to fish, 
wildlife, and related environmental values. To minimize both the amount 
of land disturbed and the length of stream segments buried or otherwise 
adversely affected, proposed 30 CFR 780.35(b)(3) provides that 
premining elevations would not operate as a cap on the elevation of 
backfilled areas. Instead, the final elevation would be determined on 
the basis of the factors listed in proposed 30 CFR 780.35(b)(2)(ii) 
through (v), together with the requirement in 30 CFR 780.35(b)(3) that 
the final surface configuration be compatible with the natural drainage 
pattern and the surrounding terrain.

---------------------------------------------------------------------------

    Proposed paragraph (a)(2) is substantively identical to existing 
paragraph (g), with the exception of a proposed requirement that 
backfilling and grading be conducted in a manner that minimizes the 
creation of uniform slopes and cut-and-fill terraces. Both uniform 
slopes and cut-and-fill terraces are rarely found in nature and thus 
normally would not be considered consistent with the concept of 
approximate original contour restoration. However, the definition of 
approximate original contour in section 701(2) of SMCRA \675\ contains 
language allowing terracing. Therefore, the proposed rule would 
continue to allow the construction of cut-and-fill terraces under 
certain conditions for specified purposes, as in the existing rules.
---------------------------------------------------------------------------

    \675\ 30 U.S.C. 1291(2).
---------------------------------------------------------------------------

    Proposed paragraph (a)(3), like existing paragraph (a)(2), would 
require the elimination of all highwalls, spoil piles, and depressions, 
with certain exceptions. We propose to add impoundments to this list 
for clarity, although this addition would not be a substantive change.
    Proposed paragraph (a)(3)(i)(A), like existing paragraph (h), would 
allow the construction of small depressions if they are needed to 
retain moisture, minimize erosion, create or enhance wildlife habitat, 
or assist revegetation. Proposed paragraph (a)(3)(i) would add two 
other requirements that must be met before small depressions may be 
created or retained. First, proposed paragraph (a)(3)(i)(B) would 
require that the depressions be consistent with the hydrologic 
reclamation plan approved in the permit in accordance with proposed 30 
CFR 780.22. Second, proposed paragraph (a)(3)(i)(C) would require that 
the permittee demonstrate that the depressions would not result in 
elevated levels of parameters of concern (e.g., total dissolved solids 
and selenium) in discharges from the backfilled and graded area. The 
two new requirements are intended to ensure protection of the 
hydrologic balance in accordance with section 515(b)(10) of SMCRA,\676\ 
which provides that surface coal mining and reclamation operations must 
be conducted to ``minimize the disturbances to the prevailing 
hydrologic balance at the mine-site and in associated offsite areas and 
to the quality and quantity of water in surface and ground water 
systems both during and after surface coal mining operations and during 
reclamation.'' Proposed paragraphs (a)(3)(i)(B) and (C) also would 
improve implementation of section 515(b)(3) of SMCRA,\677\ which 
requires, in pertinent part, that surface coal mining and reclamation 
operations shape and grade overburden or spoil ``in such a way as to 
prevent * * * water pollution.''

    \677\ 30 U.S.C. 1265(b)(3).
---------------------------------------------------------------------------

    Proposed paragraph (a)(3)(ii), like existing paragraph (i), would 
allow the retention of permanent impoundments if they are suitable for 
the approved postmining land use and if they meet the requirements of 
30 CFR 816.49 and 816.56. We propose to add a provision allowing the 
retention of permanent impoundments only if the permittee has 
demonstrated compliance with the future maintenance requirements of 
proposed 30 CFR 800.42(c)(5). The new provision would improve 
implementation of section 519(c)(2) of SMCRA,\678\ which provides that 
``[w]here a silt dam is to be retained as a permanent impoundment 
pursuant to section 515(b)(8) \679\ [the statutory counterpart to 30 
CFR 816.49(b)],''

[[Page 44569]]

Phase II bond may be released ``so long as provisions for sound future 
maintenance by the operator or the landowner have been made with the 
regulatory authority.'' In addition, proposed paragraph (a)(3)(ii)(D) 
would specify that the permittee must have obtain all necessary 
approvals and authorizations under section 404 of the Clean Water Act 
before a previously temporary impoundment may be retained as a 
permanent impoundment. This provision would apply only when the 
impoundment is located in waters of the United States. It is intended 
to encourage coordination and cooperation with the Clean Water Act 
permitting authority.

    Proposed paragraph (a)(3)(iii), like existing paragraph (a)(2), 
would allow the permittee to retain highwalls on previously mined areas 
to the extent provided in Sec.  816.106(b).
    Proposed paragraph (a)(3)(iv) would allow retention of modified 
highwall segments to the extent necessary to replace similar natural 
landforms; i.e., cliffs or bluffs, removed by the mining operation. The 
proposed rule would harmonize two provisions of section 515(b)(3) of 
SMCRA \680\ that may pose a potential conflict in certain situations: 
the requirement to restore the approximate original contour and the 
requirement to eliminate all highwalls. The proposed rule would allow 
the retention of highwall segments to replace cliffs or bluffs 
destroyed by mining, but only if the highwall segments are modified to 
closely resemble the features destroyed by mining and to restore the 
ecological functions of those features. For example, ledges may need to 
be blasted into the highwall face to provide nesting habitat for 
raptors and other cliff-dwelling wildlife and microhabitats may need to 
be created at the base of the highwall remnant. The proposed rule would 
specify that the number, length, and height of any modified highwall 
segments retained may not exceed the number, length, and height of the 
premining features that they replace. In addition to harmonizing 
potentially-conflicting requirements within section 515(b)(3) of 
SMCRA,\681\ the proposed rule would require restoration of valuable 
wildlife habitat, which would improve implementation of section 
515(b)(24) of SMCRA.\682\ Section 515(b)(24) requires that, to the 
extent possible, surface coal mining and reclamation operations use the 
best technology currently available to minimize disturbances and 
adverse impacts on fish, wildlife, and related environmental values and 
to achieve enhancement of those resources where practicable.

    Under the proposed rule, the regulatory authority would have to 
amend its regulatory program to establish the conditions under which 
highwall segments may be retained and the modifications that must be 
made to those highwall segments to ensure that the retained segment 
restores the form and ecological function of similar premining 
landforms. We have already approved highwall retention provisions of 
this nature as part of the New Mexico and Utah regulatory 
programs.\683\

---------------------------------------------------------------------------

    The New Mexico program provision, CSMC Rule 20-102(a)(2), allows 
the retention of limited stretches of highwall if similar features were 
part of the natural landscape of the mine area prior to mine 
operations. In addition, the following requirements apply:
     The highwall must have a static safety factor of 1.3.
     The highwall must not pose a hazard to persons or wildlife 
in the area.
     The highwall must be backfilled to cover the uppermost 
coal seam to a minimum depth of 4 feet.
     The retained portion of the highwall may not exceed 800 
feet in length and must be a minimum of at least 3,000 feet from any 
other portion of any other highwall remnant approved for retention as 
part of the postmining land use.
     The highwall is necessary to replace cliff-type habitats 
that existed in the natural topography prior to mining.
     The ends of the highwall left standing must be contoured 
into the surrounding topography with slopes of 3:1 or less.
    The Utah program provision (Utah Administrative Code R645-301-
553.650) allows a permittee to seek approval to retain highwalls when 
the proposed highwall remnant would meet all stability requirements and 
the following criteria:
     The remaining highwall will not be greater in height or 
length than the cliffs and cliff-like escarpments that were replaced or 
disturbed by the mining operations.
     The remaining highwall will replace a preexisting cliff or 
similar natural premining feature and will resemble the structure, 
composition, and function of the natural cliff it replaces.
     The remaining highwall will be modified, if necessary, as 
determined by the regulatory authority, to restore cliff-type habitats 
used by the flora and fauna existing prior to mining.
     The remaining highwall will be compatible with the 
postmining land use and the visual attributes of the area.
     The remaining highwall will be compatible with the 
geomorphic processes of the area.
    We invite comment on whether we should include any of these 
specific state program criteria in our rule for national applicability.
    Proposed paragraph (a)(4) is substantively identical to existing 
paragraph (a)(3).
    Proposed paragraph (a)(5), like existing paragraph (a)(4), would 
require that backfilling and grading be conducted to minimize erosion 
and water pollution both on and off the site. We propose to add 
language clarifying that the requirement to minimize water pollution 
includes discharges of parameters of concern for which no numerical 
effluent limitations or water quality standards have been established. 
Our proposed revision is in accordance with section 515(b)(10) of 
SMCRA,\684\ which provides that surface coal mining and reclamation 
operations must be conducted to ``minimize the disturbances to the 
prevailing hydrologic balance at the mine-site and in associated 
offsite areas and to the quality and quantity of water in surface and 
ground water systems both during and after surface coal mining 
operations and during reclamation.''

    Proposed paragraph (a)(6) is identical to existing paragraph

Proposed Paragraph (b)
    Existing paragraph (b) requires that all spoil except excess spoil 
disposed of in accordance with 30 CFR 816.71 or 816.74 be returned to 
the mined-out area. We propose to revise this paragraph by adding an 
exception in proposed paragraph (b)(2) for mountaintop removal mining 
operations. Under section 515(c)(4)(E) of SMCRA,\685\ spoil from 
mountaintop removal mining operations need not be returned to the 
mined-out area, provided any spoil not returned to the mined-out area 
is placed in accordance with the excess spoil disposal requirements of 
section 515(b)(22) of SMCRA.\686\ Mountaintop removal mining operations 
are designed to create a level plateau or gently rolling contour where 
mountainous topography existed before mining, which limits the amount

of spoil that can be returned to the mined-out area.

    Proposed paragraph (b)(3) would include the exception in existing 
paragraph (d) for spoil used to blend the mined-out area into the 
surrounding terrain, with revisions to reflect our proposed changes to 
30 CFR 816.22 concerning the salvage, storage, redistribution, and use 
of soil materials and organic matter. We also propose to remove 
existing paragraph (d)(3), which requires that spoil used for blending 
be backfilled and graded in accordance with the requirements of 30 CFR 
816.102. Existing paragraph (d)(3) is redundant because the 
requirements of 30 CFR 816.102 automatically apply to all backfilling 
and grading activities unless specifically exempted.
Proposed Paragraph (c)
    Existing paragraph (c) requires the compaction of spoil and waste 
materials where advisable to ensure stability or to prevent the 
leaching of toxic materials. For clarity and consistency with the 
terminology used elsewhere in our regulations, we propose to replace 
the phrase ``the leaching of toxic materials'' with ``the formation of 
acid or toxic mine drainage.''
    We also propose to add a requirement to avoid compacting materials 
placed in what will be the root zone of the species planted under the 
revegetation plan approved in the permit in accordance with proposed 30 
CFR 780.12(g) to the extent possible. As discussed in the portion of 
this preamble concerning proposed 30 CFR 780.12(e) and 816.22, soil 
compaction is a major inhibitor of plant growth and productivity, 
especially for trees and shrubs. Therefore, compaction of the root zone 
must be minimized to achieve the revegetation requirements of section 
515(b)(19) of SMCRA \687\ and the postmining land use capability 
requirements of section 515(b)(2) of SMCRA.\688\

Proposed Paragraph (d)
    Proposed paragraph (d) would include existing paragraph (f), which 
requires the covering or treatment of all exposed coal seams and acid-
forming materials, toxic-forming materials, and combustible materials. 
We propose to revise the existing rule by establishing separate 
requirements for exposed coal seams, acid-forming and toxic-forming 
materials, and combustible materials to reflect the different nature of 
these materials and to clarify which requirements apply to which 
materials.
    Proposed paragraph (d)(1) would require that all exposed coal seams 
be covered with material that is noncombustible, nonacid-forming, and 
nontoxic-forming to prevent coal seam fires and the development of acid 
or toxic mine drainage. Proposed paragraph (d)(2) would require that 
all other combustible materials exposed, used, or produced during 
mining be handled and disposed of in accordance with 30 CFR 816.89 
(noncoal waste materials) in a manner that will prevent sustained 
combustion. Proposed paragraph (d)(3) would require that the permittee 
handle and place all other acid-forming or toxic-forming materials in 
compliance with the plan approved in the permit in accordance with 
proposed 30 CFR 780.12(d)(4); in compliance with 30 CFR 816.38, which 
governs the handling and placement of acid-forming and toxic-forming 
materials; in compliance with the hydrologic reclamation plan approved 
in the permit in accordance with proposed 30 CFR 780.22(a); and in a 
manner that will minimize adverse effects on plant growth and the 
approved postmining land use.
    The proposed revisions described above would improve implementation 
of section 515(b)(10) of SMCRA,\689\ which provides that surface coal 
mining and reclamation operations must be conducted to ``minimize the 
disturbances to the prevailing hydrologic balance at the mine-site and 
in associated offsite areas and to the quality and quantity of water in 
surface and ground water systems both during and after surface coal 
mining operations and during reclamation.'' They also would more fully 
implement those provisions of section 515(b)(3) of SMCRA \690\ that 
discuss the handling of acid-forming and toxic materials during 
backfilling and grading, as well as section 515(b)(14) of SMCRA,\691\ 
which contains requirements for the handling and disposal of acid-
forming and toxic materials and materials constituting a fire hazard.

Proposed Paragraph (e)
    We propose to revise this paragraph by updating the terminology to 
reflect our 1983 rulemaking in which we introduced the term ``coal mine 
waste'' to include both coal processing waste and underground 
development waste.\692\

---------------------------------------------------------------------------

Proposed Paragraph (f)
    Proposed paragraph (f) is substantively identical to existing 
paragraph (j) except that we propose to revise this paragraph by 
replacing the references to ``topsoil'' with the term ``soil 
materials'' to be consistent with our proposed changes to 30 CFR 
816.22.
32. Section 816.104: What special provisions for backfilling, grading, 
and surface configuration apply to sites with thin overburden?
    We propose to revise this section, which implements the thin 
overburden exception in section 515(b)(3) of SMCRA,\693\ for clarity. 
Our proposed revisions to existing paragraph (a) would resolve 
ambiguities and convert the definition to a description of the 
situations in which the thin overburden provisions of 30 CFR 816.104 
would apply. In proposed paragraph (a)(1), we propose to replace the 
term ``land'' with ``mined area'' to emphasize that the determination 
as to whether the postmining surface configuration closely resembles 
the premining surface configuration must be made with respect to the 
mined area, not the surrounding area. We also propose to insert ``any'' 
before ``mining'' to clarify that, when the permit area has been 
previously mined, the premining surface configuration must be the 
surface configuration that existed before any mining, not the surface 
configuration of the existing previously mined area. The preamble to 
our proposed revisions to the definition of approximate original 
contour in 30 CFR 701.5 contains further discussion of these matters.
---------------------------------------------------------------------------

    \693\ 30 U.S.C. 1265(b)(3).
---------------------------------------------------------------------------

    In proposed paragraph (b), we propose to retain the existing 
performance standards for thin overburden at 30 CFR 816.104(b)(1) and 
(2), with appropriate plain language and citation changes. Among other 
things, the existing standards require that the permittee use all spoil 
and waste materials available from the entire permit area to attain the 
lowest practicable grade that does not exceed the angle of repose. This 
requirement is consistent with section 515(b)(3) of SMCRA,\694\ which 
provides--
---------------------------------------------------------------------------

    \694\ Id.

    That in surface coal mining which is carried out at the same 
location over a substantial period of time where the operation 
transects the coal deposit, and the thickness of the coal deposits 
relative to the volume of the overburden is large and where the 
operator demonstrates that the overburden and other spoil and waste 
materials at a particular point in the permit

[[Page 44571]]

area or otherwise available from the entire permit area is 
insufficient, giving due consideration to volumetric expansion, to 
restore the approximate original contour, the operator, at a 
minimum, shall backfill, grade, and compact (where advisable) using 
all available overburden and other spoil and waste materials to 
attain the lowest practicable grade but not more than the angle of 
repose, to provide adequate drainage and to cover all acid-forming 
and other toxic materials, in order to achieve an ecologically sound 
---------------------------------------------------------------------------
land use compatible with the surrounding region[.]

    We propose to add a reminder that the permittee must backfill all 
mined areas and grade all disturbed areas in accordance with the 
backfilling and grading plan approved in the permit under proposed 30 
CFR 780.12(d). We also propose to require that the permittee ensure 
that the final surface configuration blends into and complements the 
drainage pattern of the surrounding terrain to the extent possible. 
This requirement is intended to harmonize the reclaimed area with 
surrounding areas.
33. Section 816.105: What special provisions for backfilling, grading, 
and surface configuration apply to sites with thick overburden?
    We propose to revise this section, which implements the thick 
overburden exception in section 515(b)(3) of SMCRA,\695\ for clarity. 
Our proposed revisions to existing paragraph (a) would resolve 
ambiguities and convert the definition to a description of the 
situations in which the thick overburden provisions of 30 CFR 816.105 
would apply. In proposed paragraph (a)(1), we propose to replace the 
term ``land'' with ``mined area'' to emphasize that the determination 
as to whether the postmining surface configuration closely resembles 
the premining surface configuration must be made with respect to the 
mined area, not the surrounding area. We also propose to insert ``any'' 
before ``mining'' to clarify that, when the permit area has been 
previously mined, the premining surface configuration must be the 
surface configuration that existed before any mining, not the surface 
configuration of the existing previously mined area. The preamble to 
our proposed revisions to the definition of approximate original 
contour in 30 CFR 701.5 contains further discussion of these matters.
---------------------------------------------------------------------------

    \695\ 30 U.S.C. 1265(b)(3).
---------------------------------------------------------------------------

    We also propose to delete the provision in our existing rules that 
a thick overburden situation exists when the amount of material to be 
returned to the mined-out area is so large that it is not possible to 
achieve a surface configuration that blends into and complements the 
drainage pattern of the surrounding terrain. We are aware of no 
circumstances in which this situation would exist.
    We propose to revise the performance standards for thick overburden 
operations in existing paragraph (b) by adding an introductory reminder 
that all backfilling and grading activities must comply with the 
backfilling and grading plan approved in the permit under proposed 30 
CFR 780.12(d). We also propose to revise existing paragraph (b) to 
improve consistency with the underlying statutory provisions and to 
reflect other rule changes that we are proposing. In relevant part, 
section 515(b)(3) of SMCRA \696\ provides--
---------------------------------------------------------------------------

    \696\ 30 U.S.C. 1265(b)(3).

    That in surface coal mining where the volume of overburden is 
large relative to the thickness of the coal deposit and where the 
operator demonstrates that due to volumetric expansion the amount of 
overburden and other spoil and waste materials removed in the course 
of the mining operation is more than sufficient to restore the 
approximate original contour, the operator shall after restoring the 
approximate original contour, backfill, grade, and compact (where 
advisable) the excess overburden and other spoil and waste materials 
to attain the lowest grade but not more than the angle of repose, 
and to cover all acid-forming and other toxic materials, in order to 
achieve an ecologically sound land use compatible with the 
surrounding region and that such overburden or spoil shall be shaped 
and graded in such a way as to prevent slides, erosion, and water 
pollution and is revegetated in accordance with the requirements of 
---------------------------------------------------------------------------
the Act[.]

    To implement this provision, proposed 30 CFR 816.105(b)(1) would 
require that the permittee backfill the mined-out area to the 
approximate original contour and then place the remaining spoil and 
waste materials on top of the backfilled area to the extent possible, 
as determined in accordance with the excess spoil minimization 
requirements of proposed 30 CFR 780.35(b). Section 515(b)(3) of SMCRA 
could be interpreted as requiring return of all spoil and waste 
materials to the mined-out area, but such a reading would not be the 
best interpretation of the statute. Nor is it technically possible to 
return all spoil from many steep-slope mining operations to the mined-
out area.
    Section 515(b)(22) of SMCRA \697\ recognizes that mining operations 
may generate excess spoil. Accordingly, it establishes requirements 
governing placement of excess spoil outside the mined-out area. To 
harmonize these two statutory provisions, proposed 30 CFR 816.105(b)(1) 
would require adherence to the excess spoil minimization requirements 
in proposed 30 CFR 780.35(b) to ensure that spoil and waste materials 
are returned to the mined-out area to the extent possible after 
considering the technical, postmining land use, environmental, and 
other factors listed in proposed 30 CFR 780.35(b)(2)(i) through (v).
---------------------------------------------------------------------------

    \697\ 30 U.S.C. 1265(b)(22).
---------------------------------------------------------------------------

    Proposed 30 CFR 816.105(b)(2) would require that the spoil and 
waste materials placed on top of the backfilled area be graded to the 
lowest practicable grade that is ecologically sound, consistent with 
the postmining land use, and compatible with the surrounding region. No 
slope may exceed the angle of repose. Proposed paragraph (b)(2) would 
be consistent with the language in section 515(b)(3) of SMCRA,\698\ 
which requires that the operator ``backfill, grade, and compact (where 
advisable) the excess overburden and other spoil and waste materials to 
attain the lowest grade but not more than the angle of repose * * * in 
order to achieve an ecologically sound land use compatible with the 
surrounding region.''
---------------------------------------------------------------------------

    \698\ 30 U.S.C. 1265(b)(3).
---------------------------------------------------------------------------

    Proposed 30 CFR 816.105(b)(3), like existing 30 CFR 816.105(b)(2), 
would continue to require compliance with most of the backfilling, 
spoil and soil placement, grading, and surface configuration 
requirements of 30 CFR 816.102, with the notable exception of the 
requirement in 30 CFR 816.102(a)(1) for restoration of the approximate 
original contour as the final surface configuration. Among other 
things, proposed paragraph (b)(3) would implement or facilitate 
implementation of those provisions of section 515(b)(3) of SMCRA that 
require (1) covering of all acid-forming and other toxic materials, (2) 
compaction of spoil and waste materials where advisable, (3) shaping 
and grading of overburden and spoil ``in such a way as to prevent 
slides, erosion, and water pollution,'' and (4) revegetation.
    Proposed 30 CFR 816.105(b)(4), like existing 30 CFR 816.105(b)(3), 
would continue to require that any excess spoil be placed in accordance 
with the excess spoil disposal requirements of 30 CFR 816.71 or 816.74. 
As provided in our proposed definition of excess spoil in 30 CFR 701.5, 
this requirement would apply to all spoil material placed above the 
approximate original contour within the mined-out area as part of the 
continued construction of an excess spoil fill with a toe located 
outside the mined-out area.

[[Page 44572]]

    Proposed paragraph (b)(5) would require that the final surface 
configuration blend into and complement the drainage pattern of the 
surrounding terrain to the extent possible. This requirement is 
intended to harmonize the reclaimed area with surrounding areas.
34. Section 816.106: What special provisions for backfilling, grading, 
and surface configuration apply to previously mined areas with a 
preexisting highwall?
    We propose to modify the cross-references in existing paragraph (b) 
to be consistent with the other rule changes that we are proposing 
today. We also propose to revise the language of existing paragraph (b) 
to clarify that it does not grant an exception to any of the general 
backfilling and grading requirements of 30 CFR 816.102 except the 
requirement to eliminate all highwalls. All other proposed changes 
would improve adherence to plain language principles and are 
nonsubstantive.
35. Section 816.107: What special provisions for backfilling, grading, 
and surface configuration apply to steep slopes?
    We propose to revise existing paragraph (d) of this section, which 
governs the disposal of woody materials on steep-slope mining sites, 
for consistency with proposed 30 CFR 816.22(f). The existing rule 
provides that woody materials may not be buried in the backfill unless 
the regulatory authority determines that doing so would not create 
stability problems. However, as discussed in the preamble to proposed 
30 CFR 816.22(f), woody materials are sufficiently valuable for 
revegetation and fish and wildlife enhancement purposes that they 
should be used for those purposes rather than being buried or burned. 
Therefore, we propose to revise 30 CFR 816.107(d) to prohibit the 
burial of woody materials in the backfill and to require that the 
permittee instead handle those materials in accordance with proposed 30 
CFR 816.22(f).
36. Section 816.111: How must I revegetate the area disturbed by 
mining?
    We propose to revise and restructure this section for clarity and 
consistency with other proposed rule changes. We also propose to move 
existing paragraphs (b) and (c) and most of existing paragraph (d) to 
proposed 30 CFR 780.12(g) because they are permitting requirements that 
pertain to development of the revegetation plan. We propose to delete 
the sentence in existing paragraph (d) stating that the requirements of 
30 CFR part 823 apply to prime farmland. This sentence is unnecessary 
because by its own terms 30 CFR part 823 applies to all prime farmland. 
In addition, we propose to redesignate existing 30 CFR 816.113 and 
816.114 as proposed paragraphs (e) and (d), respectively, of 30 CFR 
816.111.
    Most of our proposed substantive revisions are intended to improve 
the implementation of section 515(b)(2) of SMCRA,\699\ which requires 
that surface coal mining and reclamation operations ``restore the land 
affected to a condition capable of supporting the uses which it was 
capable of supporting prior to any mining, or higher or better uses of 
which there is reasonable likelihood,'' and section 515(b)(19) of 
SMCRA,\700\ which provides that surface coal mining and reclamation 
operations must--
---------------------------------------------------------------------------

    \699\ 30 U.S.C. 1265(b)(2).
    \700\ 30 U.S.C. 1265(b)(19).

establish on the regraded areas, and on all other lands affected, a 
diverse, effective, and permanent vegetation cover of the same 
seasonal variety native to the area of land to be affected and 
capable of self-regeneration and plant succession at least equal in 
extent of cover to the natural vegetation of the area; except, that 
introduced species may be used in the revegetation process where 
desirable and necessary to achieve the approved postmining land use 
---------------------------------------------------------------------------
plan[.]

    The proposed revisions are necessary in part because an approved 
higher or better postmining land use is not always implemented during 
the revegetation responsibility period. Requiring initial revegetation 
with native species would promote environmentally-sound reclamation and 
enhance fish and wildlife habitat without precluding implementation of 
the higher or better use at a later date. The increased emphasis on 
revegetation with native species also would prevent proliferation of 
instances in which backfilled and graded minesites have not been 
revegetated with a permanent vegetative cover of the same seasonal 
variety native to the area, as required by section 515(b)(19) of SMCRA.
Proposed Paragraph (a)
    We propose to revise existing paragraph (a) to clarify that the 
revegetation requirements of 30 CFR 816.111 do not apply to rock piles 
and other rock or non-vegetative features created to restore or enhance 
wildlife habitat under the fish and wildlife protection and enhancement 
plan approved in the permit in accordance with 30 CFR 780.16. We also 
propose to clarify that the revegetation exemption also applies to any 
other area that contains an impervious surface, such as a building or a 
parking lot, approved as part of or in support of the postmining land 
use and constructed before expiration of the revegetation 
responsibility period. Finally, we propose to clarify that the 
revegetation exemption for water areas applies only to water areas 
approved as part of or in support of the postmining land use or 
approved as part of the fish and wildlife protection and enhancement 
plan in the permit.
Proposed Paragraph (b)
    Proposed paragraph (b) would require that the reestablished 
vegetative cover comply with the revegetation plan approved in the 
permit in accordance with proposed 30 CFR 780.12(g). It also would 
require that the vegetative cover be consistent with both the approved 
postmining land use and establishment of the plant communities 
described in the permit application as required by proposed 30 CFR 
779.19. In addition, proposed paragraph (b) would require that the 
vegetative cover be capable of stabilizing the soil surface and, in the 
long term, preventing erosion in excess of what would have occurred 
naturally had the site not been disturbed. Background erosion levels on 
undisturbed sites vary from region to region and site to site, 
depending on geology, soils, topography, and climate. Further, proposed 
paragraph (b) would require that the vegetative cover not inhibit the 
establishment of woody plants when the revegetation plan requires the 
use of woody plants.
    Extensive herbaceous ground cover can inhibit the establishment and 
growth of trees and shrubs, which would provide more effective long-
term surface stabilization and erosion control in areas that are 
naturally forested. The dense herbaceous ground covers often used in 
the past to control erosion on regraded sites compete with newly-
planted trees and tree seedlings for soil nutrients, water, and 
sunlight and provide habitat and cover for rodents and other animals 
that damage tree seedlings and young trees. An article in a technical 
publication provides the following summary of the effects of ground 
cover on establishment of trees on mined lands:

    The negative effects of overly abundant and aggressive ground 
cover on the survival and growth of trees planted on reclaimed mine 
lands has long been known. Trees planted into introduced, aggressive 
forages [especially tall fescue and sericea lespedeza] often are 
overtopped by the grass or legume and are unable to break free 
(Burger and Torbert, 1992; Torbert et al., 1995). The seedlings are 
pinned to the ground and have

[[Page 44573]]

little chance for survival. If it is known that trees are to be 
planted, a tree-compatible ground cover should be seeded that will 
be less competitive with trees. Tree-compatible ground cover should 
be slow growing, sprawling or low growing, not allopathic, and non-
competitive with trees (Burger and Torbert, 1992). Plass (1968) 
reported that after four growing seasons the height growth of 
sweetgum and sycamore planted into an established stand of tall 
fescue on spoil banks was significantly retarded. Andersen et al. 
(1989) found that survival and height growth for red oak and black 
walnut was significantly greater on sites where ground cover was 
chemically controlled.\701\

    Researchers from the University of Maine determined that even a 
small amount (less than 20 percent) of herbaceous ground cover around 
tree seedlings will substantially reduce early stand growth.\702\ 
Another study of revegetation of mined lands in Appalachia found that 
dense ground covers prevent the natural seeding-in of native plants, 
while low ground cover seeding rates allowed the invasion of light-
seeded native trees such as yellow poplar, red maple, and birches.\703\

---------------------------------------------------------------------------

    The amount of vegetative ground cover necessary to control erosion 
on any particular site is a function of the site topography, 
composition of the surface material, precipitation frequency and 
intensity, and the degree of soil compaction. Loosely graded or 
uncompacted material, particularly if placed on a relatively gentle 
slope, may have virtually no runoff or erosion and would require little 
or no herbaceous vegetative ground cover to control erosion. 
Conversely, highly-compacted material placed on a steep slope severely 
limits infiltration and increases runoff so that a dense vegetative 
cover may be needed to control erosion.
    We invite comment on whether proposed paragraphs (b)(4) and (5) 
strike the proper balance between the need for erosion control and the 
conditions required to promote establishment of native trees and 
shrubs, or whether adjustments are needed.
Proposed Paragraph (c)
    Proposed paragraph (c) would allow volunteer plants of species that 
are desirable components of the plant communities described in the 
permit application under proposed 30 CFR 779.19 and that are not 
inconsistent with the postmining land use to be considered in 
determining whether the revegetation requirements of 30 CFR 816.111 and 
816.116 have been met. Proposed paragraph (c) would be consistent with 
existing practice and with the requirement to establish a vegetative 
cover capable of self-regeneration and plant succession in section 
515(b)(19) of SMCRA.\704\

    \704\ 30 U.S.C. 1265(b)(19).
---------------------------------------------------------------------------

Proposed Paragraph (d)
    Proposed paragraph (d), which would include existing 30 CFR 
816.114, would require that all areas upon which soil materials have 
been redistributed be stabilized either by establishing a temporary 
vegetative cover consisting of noncompetitive and non-invasive species 
or by applying a hay mulch (native hay would be required when 
commercially available) that is free of weed and noxious plant seeds. 
These methods could be used alone or in combination. In addition, 
proposed paragraph (d) would allow the regulatory authority to waive 
this requirement if it determines that neither method is necessary to 
stabilize the surface and control erosion. Proposed paragraph (d) is 
intended to promote establishment of ``a diverse, effective, and 
permanent vegetative cover of the same seasonal variety native to the 
area of land to be affected and capable of self-regeneration and plant 
succession,'' as required by section 515(b)(19) of SMCRA.\705\ The 
preamble to proposed paragraph (b) explains the obstacle that dense 
herbaceous ground covers comprised of aggressive perennial species like 
tall fescue and sericea lespedeza present to the establishment of trees 
and shrubs and, hence, to achieving the type of postmining plant 
community that SMCRA requires.

Proposed Paragraph (e)
    Proposed paragraph (e), which concerns the timing of revegetation, 
is substantively identical to existing 30 CFR 816.113. We propose to 
add a cross-reference to the revegetation plan approved in the permit 
in accordance with proposed 30 CFR 780.12(g).
37. Why are we proposing to remove existing 30 CFR 816.113 and 816.114?
    We propose to consolidate existing 30 CFR 816.113 and 816.114 into 
30 CFR 816.111 with the other general performance standards for 
revegetation. We propose to redesignate 30 CFR 816.113 and 816.114 as 
30 CFR 816.111(e) and (d), respectively.
38. Section 816.115: How long am I responsible for revegetation after 
planting?
    Proposed 30 CFR 816.115 is substantively identical to the 
provisions concerning revegetation responsibility periods in existing 
30 CFR 816.116(c), with one exception.
    Proposed paragraph (a)(2) would provide that the initial planting 
of small areas that are regraded and planted as a result of the removal 
of sediment control structures and associated structures and facilities 
(e.g., diversion ditches, disposal and storage areas for accumulated 
sediment, sediment pond embankments, and ancillary roads used to access 
those structures) need not be considered an augmented seeding 
necessitating an extended or separate revegetation responsibility 
period. This proposed paragraph is not a new proposal; its adoption 
would merely incorporate into regulation the policy upon which we 
previously provided notice and opportunity for comment \706\ and 
subsequently adopted in the context of the approval of several state 
regulatory program amendments.\707\
---------------------------------------------------------------------------

    \706\ See 58 FR 48333 (Sept. 15, 1993).
    \707\ See, e.g., Colorado (61 FR 26792, 26796-26797 (May 29, 
1996)), Illinois (62 FR 55765-55769 Oct. 22, 1997)), and Ohio (63 FR 
51829-51833 (Sept. 29, 1998)).
---------------------------------------------------------------------------

    The following discussion from the preamble to our approval of the 
Illinois program amendment sets forth the rationale for our policy:

    Section 515(b)(20) of SMCRA provides that the revegetation 
responsibility period shall commence ``after the last year of 
augmented seeding, fertilizing, irrigation, or other work'' needed 
to assure revegetation success. In the absence of any indication of 
Congressional intent in the legislative history, OSM interprets this 
requirement as applying to the increment or permit area as a whole, 
not individually to those lands within the permit area upon which 
revegetation is delayed solely because of their use in support of 
the reclamation effort on the planted area. As implied in the 
preamble discussion of 30 CFR 816.46(b)(5), which prohibits the 
removal of ponds or other siltation structures until two years after 
the last augmented seeding, planting of the sites from which such 
structures are removed need not itself be considered an augmented 
seeding necessitating an extended or separate liability period (48 
FR 44038-44039, September 26, 1983).
    The purpose of the revegetation responsibility period is to 
ensure that the mined area has been reclaimed to a condition capable 
of supporting the desired permanent vegetation. Achievement of this 
purpose will not be adversely affected by this

[[Page 44574]]

interpretation of section 515(b)(20) of SMCRA since (1) the lands 
involved are relatively small in size and either widely dispersed or 
narrowly linear in distribution and (2) the delay in establishing 
revegetation on these sites is due not to reclamation deficiencies 
or the facilitation of mining, but rather to the regulatory 
requirement that ponds and diversions be retained and maintained to 
control runoff from the planted area until the revegetation is 
sufficiently established to render such structure unnecessary for 
the protection of water quality.
    In addition, the areas affected likely would be no larger than 
those which could be reseeded (without restarting the revegetation 
period) in the course of performing normal husbandry practices, as 
that term is defined in 30 CFR 816.116(c)(4) and explained in the 
preamble to that rule (53 FR 34636, 34641; September 7, 1988; 52 FR 
28012, 28016; July 27, 1987). Areas this small would have a 
negligible impact on any evaluation of the permit area as a whole.
    Most importantly, this interpretation is unlikely to adversely 
affect the regulatory authority's ability to make a statistically 
valid determination as to whether a diverse, effective permanent 
vegetative cover has been successfully established in accordance 
with the appropriate revegetation success standards. From a 
practical standpoint, it is usually difficult to identify precisely 
where such areas are located in the field once revegetation is 
established in accordance with the approved reclamation plan.\708\
---------------------------------------------------------------------------

    \708\ 62 FR 55766 (Oct. 22, 1997).

    Neither the policy nor the state program amendment approvals extend 
to the removal of haul roads or other primary roads. Because of the 
difficulty in reestablishing vegetation on the surfaces of primary 
roads, that type of road may need to be bonded separately for purposes 
of the revegetation liability period, unless the road is approved for 
retention as part of the postmining land use.
39. Section 816.116: What are the standards for determining the success 
of revegetation?
    We propose to reorient our regulations concerning revegetation 
success standards away from focusing on a single postmining land use, 
which may or may not be implemented, to standards pertinent to a 
determination of whether the site has been restored ``to a condition 
capable of supporting the uses which it was capable of supporting prior 
to any mining, or higher or better uses of which there is reasonable 
likelihood,'' as required by section 515(b)(2) of SMCRA.\709\ In 
effect, the standards would have to reflect the premining land use 
capability and productivity information provided in the permit 
application in accordance with proposed 30 CFR 779.22(b). This approach 
is also consistent with the legislative history of section 508 of 
SMCRA,\710\ in which Congress states: ``It is important that the 
potential utility which the land had for a variety of uses be the 
benchmark rather than any single, possibly low value, use which by 
circumstances may have existed at the time mining began.'' \711\

    \711\ S. Rept. 95-128, 95th Cong., 1st Sess. 76-77 (1977).
---------------------------------------------------------------------------

    We propose to require that minesites be revegetated in a manner 
that will restore the native plant communities described in the permit 
application in accordance with proposed 30 CFR 779.19, regardless of 
the approved postmining land use. The proposed rule contains an 
exception for those portions of the permit area on which the approved 
postmining land use is implemented before the end of the revegetation 
responsibility period under proposed 30 CFR 816.115, but that exception 
would apply only if restoration of native plant communities would be 
inconsistent with that use, as may be the case with agricultural, 
commercial, industrial, and residential postmining land uses. This 
approach would improve implementation of section 515(b)(19) of 
SMCRA,\712\ which provides that surface coal mining and reclamation 
operations must--
---------------------------------------------------------------------------

    \712\ 30 U.S.C. 1265(b)(19).

establish on the regraded areas, and on all other lands affected, a 
diverse, effective, and permanent vegetation cover of the same 
seasonal variety native to the area of land to be affected and 
capable of self-regeneration and plant succession at least equal in 
extent of cover to the natural vegetation of the area; except, that 
introduced species may be used in the revegetation process where 
desirable and necessary to achieve the approved postmining land use 
---------------------------------------------------------------------------
plan[.]

    Nothing in this provision of the Act suggests that revegetation 
success standards should be based solely or primarily on the postmining 
land use, with the exception of situations in which introduced species 
are desirable and necessary to achieve the postmining land use, as 
would be true of most cropland postmining land uses. Therefore, the 
approach most consistent with paragraphs (b)(2) and (b)(19) of section 
515 of SMCRA \713\ is the one that we are proposing; i.e., success 
standards that are sufficiently rigorous to demonstrate that the 
disturbed area has been restored to a condition capable of supporting 
the uses that it was capable of supporting before any mining and that 
will ensure restoration of plant communities native to the area.
---------------------------------------------------------------------------

    \713\ 30 U.S.C. 1265(b)(2) and (19).
---------------------------------------------------------------------------

    Proposed 30 CFR 816.116 would fill a gap in our existing rules by 
requiring the establishment of revegetation success standards for all 
reclaimed areas. Specifically, existing 30 CFR 816.116(b)(4) 
establishes revegetation success standards for lands with an approved 
commercial, industrial, or residential postmining land use only if that 
land use is to be implemented less than 2 years after completion of 
regrading. The existing rules are silent on revegetation success 
standards for lands with an approved commercial, industrial, or 
residential postmining land use to be implemented two or more years 
after completion of regrading.
Proposed Paragraph (a)
    Proposed paragraph (a) is substantively identical to existing 
paragraph (a)(1).
Proposed Paragraph (b)
    Proposed 30 CFR 816.116 would establish, or require the 
establishment of, revegetation success standards for all reclaimed 
areas. Proposed paragraph (b) would require that those standards be 
adequate to demonstrate restoration of premining land use capability, 
consistent with section 515(b)(2) of SMCRA.\714\ Specifically, 
revegetation success standards would have to be based upon the plant 
community and vegetation information required under proposed 30 CFR 
779.19, the soil type and productivity information required under 
proposed 30 CFR 779.21, and the land use capability and productivity 
information required under proposed 30 CFR 779.22. Revegetation success 
standards also must be based upon the postmining land use approved 
under proposed 30 CFR 780.24 if the postmining land use will be 
implemented before expiration of the revegetation responsibility 
period. Otherwise, proposed paragraph (a)(4) would require that the 
site be revegetated in a manner that will restore native plant 
communities and the revegetation success standards for the site must 
reflect that requirement, regardless of the postmining land use. 
Proposed paragraph (a)(4) would improve implementation of section 
515(b)(19) of SMCRA,\715\ which, with limited exceptions, requires 
revegetation with native species, and section 515(b)(24) of SMCRA,\716\ 
which requires that surface coal mining and reclamation operations 
minimize

[[Page 44575]]

adverse impacts on fish, wildlife, and related environmental values to 
the extent possible using the best technology currently available and 
enhance those resources where practicable.

---------------------------------------------------------------------------

    Together with our proposed changes to the soil salvage and 
redistribution requirements in proposed 30 CFR 780.12(e) and 816.22, 
the revegetation success standard requirements of proposed paragraph 
(b) would preserve the site's future land use capability in those 
situations in which the approved postmining land use is less intensive 
than other uses that the land was capable of supporting before mining. 
For example, if the approved postmining land use is pasture, but the 
land was used for cropland before mining, proposed 30 CFR 780.12(e) and 
816.22 would require that the soil be reconstructed in a manner that 
would restore the site's capability to support cropland (not just 
pasture, which does not require as deep a root zone). Similarly, 
proposed 30 CFR 816.116(b) would require that the revegetation success 
standards for the site be based in part upon row crop production, not 
just production of pasture forage and ground cover.
Proposed Paragraph (c)
    Proposed paragraph (c) would require that revegetation success 
standards include species diversity, areal distribution of species, 
ground cover (except for land actually used for cropland after the 
completion of regrading and redistribution of soil materials), 
production (for land used for cropland, pasture or grazing land either 
before permit issuance or after the completion of regrading and 
redistribution of soil materials), and stocking (for all areas 
revegetated with woody plants, regardless of the postmining land use). 
Proposed paragraph (c) is intended to provide greater specificity than 
the introductory language of existing paragraph (a), which requires 
that the success of revegetation ``be judged on the effectiveness of 
the vegetation for the approved postmining land use, the extent of 
cover compared to the cover occurring in natural vegetation of the 
area, and the general requirements of Sec.  816.111.'' Proposed 
paragraph (c) would be consistent with section 515(b)(19) of 
SMCRA,\717\ which requires establishment of ``a diverse, effective, and 
permanent vegetative cover of the same seasonal variety native to the 
area of land to be affected and capable of self-regeneration and plant 
succession at least equal in extent of cover to the natural vegetation 
of the area.'' It also would be consistent with section 515(b)(2) of 
SMCRA,\718\ which requires restoration of the land ``to a condition 
capable of supporting the uses that it was capable of supporting prior 
to any mining, or to higher or better uses * * *.''

    \718\ 30 U.S.C. 1265(b)(2).
---------------------------------------------------------------------------

Proposed Paragraph (d)
    Proposed paragraph (d) is substantively identical to the second 
sentence of existing paragraph (a)(2), which establishes statistical 
confidence requirements for revegetation sampling techniques and 
statistical adequacy standards for determining when revegetation 
success standards for ground cover, production, and stocking have been 
met. We invite comment on whether our statistical confidence interval 
requirements are appropriate in all situations.
Proposed Paragraph (e)
    Proposed paragraph (e) is substantively identical to existing 
paragraph (b)(3)(i) in that it would require that the regulatory 
authority specify minimum stocking and planting arrangements on the 
basis of local and regional conditions and after coordination with and 
approval by the state agencies responsible for the administration of 
forestry and wildlife programs. However, unlike existing paragraph 
(b)(3)(i), which applies only to areas to be developed for fish and 
wildlife habitat, recreation, undeveloped land, or forest products, 
proposed paragraph (e) would apply to all areas that are revegetated 
with woody plants, consistent with proposed paragraph (c), as discussed 
in the preamble to proposed paragraph (b). We also propose to replace 
the term ``consultation'' with ``coordination'' to avoid any confusion 
with consultation requirements and procedures under section 7(a)(2) of 
the Endangered Species Act.
Proposed Paragraph (f)
    Proposed paragraphs (f)(1) and (2) are substantively identical to 
existing paragraph (b)(3)(ii). However, proposed paragraph 
(f)(2)(iii)(A) would clarify that only those species of trees and 
shrubs approved in the permit as part of the revegetation plan under 
proposed 30 CFR 780.12(g) or volunteer trees and shrubs of species that 
meet the requirements of proposed 30 CFR 816.111(c) may be counted for 
purposes of determining whether stocking standards have been met. This 
proposed clarification is intended to ensure that only specimens of 
species consistent with section 515(b)(19) of SMCRA \719\ are counted 
in determining revegetation success.
---------------------------------------------------------------------------

    \719\ 30 U.S.C. 1265(b)(19).
---------------------------------------------------------------------------

    Existing paragraph (b)(3)(iii) requires that vegetative ground 
cover on areas planted with trees and shrubs not be less than that 
required to achieve the approved postmining land use. Proposed 
paragraph (f)(3) would replace that requirement with a provision that 
would require that vegetative ground cover on areas planted with trees 
and shrubs have characteristics that will allow for the natural 
establishment and succession of native plants, including trees and 
shrubs. The preamble to proposed 30 CFR 816.111(b) discusses the 
significance of the extent and type of ground cover to the successful 
establishment of trees and shrubs.
Proposed Paragraph (g)
    Proposed paragraph (g) is based upon existing paragraph (b)(4), 
which provides that areas to be developed for commercial, industrial, 
or residential use less than 2 years after completion of regrading need 
only meet a ground cover standard; i.e., the vegetative ground cover 
must not be less than that required to control erosion. Proposed 
paragraph (g) would revise this requirement to apply to all lands 
actually developed for commercial, industrial, or residential use 
during the revegetation responsibility period. This change would 
recognize the fact that vegetation and vegetative productivity are not 
major components of those land uses. However, because of the potential 
for abuse of this provision, the proposed rule would limit its 
applicability to only those lands actually developed for the specified 
uses, rather than all lands for which one of those uses has been 
approved as the postmining land use in the permit.
Proposed Paragraph (h)
    Proposed paragraph (h) is substantively identical to existing 
paragraph (b)(5) in that it specifies that, at a minimum, the cover on 
revegetated previously mined areas must not be less than the ground 
cover existing before redisturbance and must be adequate to control 
erosion. We also propose to clarify that previously mined areas need 
only meet a ground cover standard unless the regulatory authority 
specifies otherwise. The added language is consistent with the intent 
of the existing rule.

[[Page 44576]]

Proposed Paragraph (i)
    Proposed paragraph (i) would provide a reminder that, for prime 
farmland, the revegetation success standards in 30 CFR 823.15 apply in 
lieu of the provisions of proposed 30 CFR 816.116(b) through (h).
40. Section 816.133: What provisions concerning the postmining land use 
apply to my operation?
    We propose to revise existing paragraph (a) for clarity, to include 
cross-references to pertinent permitting requirements, and to add the 
phrase ``of which there is a reasonable likelihood'' after ``higher or 
better uses'' to be consistent with the corresponding statutory 
provision in section 515(b)(2) of SMCRA.\720\ Existing paragraphs (b) 
and (c) of this section are permitting requirements that we propose to 
move to the land use information requirements of 30 CFR 779.22 and the 
postmining land use requirements of 30 CFR 780.24. Similarly, existing 
paragraph (d) of this section consists of permitting requirements that 
we propose to consolidate with the approximate original contour 
variance provisions of 30 CFR 785.16.

41. Why are we proposing to remove the interpretive rule in existing 30 
CFR 816.200?
    This section contains only one interpretive rule, which pertains to 
the 1979 version of the topsoil substitute requirements in 30 CFR 
816.22. However, we revised 30 CFR 816.22 on May 16, 1983 (48 FR 
22100), in a manner that rendered the interpretive rule obsolete. 
Therefore, we intend to remove existing 30 CFR 816.200.

M. Part 817: Permanent Program Performance Standards--Underground 
Mining Activities.

    Part 817 contains the permanent regulatory program performance 
standards for underground mining activities. It is the counterpart to 
part 816 for surface mining activities. In general, part 817 is 
substantively identical to part 816, except for the substitution of 
``underground mining activities'' for ``surface mining activities,'' 
the replacement of references to surface mining regulations with 
references to the corresponding underground mining regulations, and 
changes of a similar nature. Our proposed revisions to part 817 are 
similarly substantively identical to the corresponding revisions that 
we propose in part 816. Therefore, this portion of the preamble 
discusses only those proposed revisions to part 817 that differ from 
the proposed revisions to the corresponding provisions of part 816. 
Otherwise, the rationale that we provide for the proposed revisions to 
part 816 applies with equal effect to our proposed revisions to part 
817.
    Section 516 of SMCRA \721\ contains the performance standards for 
underground mining operations. Section 516(b)(10) \722\ states that 
``with respect to other surface impacts not specified in this 
subsection * * *, [underground coal mining operations must] operate in 
accordance with the [performance] standards established under section 
515 of this title for such effects which result from surface coal 
mining operations.'' In other words, unless otherwise specified in 
section 516 or in the regulations implementing section 516, the 
performance standards for surface mining operations in section 515 of 
SMCRA \723\ also apply to underground mining operations under section 
516 of the Act. The following table identifies those provisions of 
section 515 for which section 516 contains a counterpart:
---------------------------------------------------------------------------

    \721\ 30 U.S.C. 1266.
    \722\ 30 U.S.C. 1266(b)(10).

(19)......................................  (6)
(21)......................................  (7)
(24)......................................  (11)
------------------------------------------------------------------------

    In general, the corresponding provisions of sections 515 and 516 
listed in the table are similar. Therefore, when reading the preamble 
to part 816 for purposes of understanding a rule proposed in part 817, 
you may use this table to convert references to section 515 in the 
preamble to part 816 to references to section 516 for purposes of part 
817.
1. Section 817.11: What signs and markers must I post?
    The existing rules contain two requirements to mark buffer zones 
for perennial and intermittent streams--one in the stream buffer zone 
rules in sections 816.57(b) and 817.57(b) and one in the rules 
concerning signs and markers in sections 816.11(e) and 817.11(e). We 
propose to consolidate those requirements in sections 816.11(e) and 
817.11(e). As revised, proposed section 817.11(e) provides that the 
boundaries of any buffer to be maintained between surface activities 
and perennial or intermittent streams in accordance with sections 
784.28 and 817.57 must be clearly marked to avoid disturbance by 
surface operations and facilities resulting from or in connection with 
an underground mine.
2. Section 817.34: How must I protect the hydrologic balance?
    This section is substantively identical to proposed 30 CFR 816.34 
for surface mines, with one exception: The underground rules do not 
contain a counterpart to proposed 30 CFR 816.34(a)(9), which would 
require that the permittee handle earth materials and runoff in a 
manner that will restore the approximate premining recharge capacity of 
the reclaimed area as a whole. Our omission of this provision from the 
underground mining rules reflects the construction of sections 515 and 
516 of SMCRA.\724\ Section 515(b)(10)(D) of SMCRA \725\ requires that 
surface coal mining operations restore the recharge capacity of the 
mined area to approximate premining conditions. However, that 
requirement does not appear in the corresponding provision for 
underground coal mining operations in section 516(b)(9) of SMCRA.\726\

---------------------------------------------------------------------------

3. Section 817.40: What responsibility do I have to replace water 
supplies?
    This section is substantively identical to proposed 30 CFR 816.40 
for surface mines, with one exception: Proposed paragraph (a)(1) 
reflects the water supply replacement requirements of section 720(a)(2) 
of SMCRA \727\ for underground mining operations rather than the water 
supply replacement requirements of section 717(b) of SMCRA \728\ for 
surface mines.

4. Section 817.44: What restrictions apply to gravity discharges from 
underground mines?
    The counterpart to this proposed rule is existing 30 CFR 817.41(i). 
We propose to revise this rule by adding a requirement in proposed 
paragraph (a)(2)(ii) that the applicant for a gravity discharge design 
the discharge control structure to prevent a mine pool blowout. We also 
propose to add paragraph (a)(3), which would require that the permittee 
construct and maintain the discharge control structure in accordance 
with the design approved by the regulatory authority and any other 
conditions imposed by the regulatory authority. The proposed

[[Page 44577]]

revisions are intended to provide for the safety of the public, protect 
property from damage by mine pool blowouts, and prevent material damage 
to the hydrologic balance outside the permit area in accordance with 
section 510(b)(3) of SMCRA.\729\
---------------------------------------------------------------------------

    \729\ 30 U.S.C. 1260(b)(3).
---------------------------------------------------------------------------

5. Section 817.57: What additional performance standards apply to 
surface activities conducted in, through, or adjacent to a perennial or 
intermittent stream?
    This section is substantively identical to proposed 30 CFR 816.57 
for surface mining activities except that, in accordance with our 
interpretation of the definition of ``surface coal mining operations'' 
in section 701(28) of SMCRA \730\ and 30 CFR 700.5, the provisions of 
30 CFR 817.57 would not apply to the surface impacts, including 
subsidence-related impacts, resulting from underground mining 
activities if there are no mining activities conducted on the surface 
of the land on which those impacts occur. However, as provided in the 
proposed definition of ``material damage to the hydrologic balance 
outside the permit area'' in 30 CFR 701.5, underground mine operators 
must conduct their operations in a manner that preserves sufficient 
flow to maintain existing and reasonably foreseeable uses of perennial 
and intermittent streams on land overlying the underground workings or 
within the angle of draw of those workings. In addition, as provided in 
the same definition, underground mine operators must conduct their 
operations in a manner that does not preclude attainment of the 
designated use or uses of perennial and intermittent streams on land 
overlying the underground workings or within the angle of draw of those 
workings.
---------------------------------------------------------------------------

    \730\ 30 U.S.C. 1291(28).
---------------------------------------------------------------------------

6. Section 817.71: How must I dispose of excess spoil?
    We propose to remove existing 30 CFR 817.71(k), which provides that 
spoil resulting from face-up operations for underground coal mine 
development may be placed at drift entries as part of a cut-and-fill 
structure if that structure is less than 400 feet in length and is 
designed in accordance with section 817.71. We propose to remove this 
paragraph because spoil excavated as part of face-up operations and 
used to construct a mine bench is not excess spoil. Under both the 
existing and proposed definitions of excess spoil in 30 CFR 701.5, 
excess spoil consists of spoil material disposed of in a location 
outside the mined-out area, but it does not include spoil needed to 
achieve restoration of the approximate original contour. In most cases, 
spoil used to construct the bench for an underground mine will later be 
used to reclaim the face-up area when coal extraction from the 
underground mine is finished. That is, the bench will be regraded to 
cover the mine entry and eliminate any highwall once mining is 
completed and the bench is no longer needed for mine offices, parking 
lots, equipment storage, conveyor belts, and other mining-related 
purposes. Consequently, this paragraph of the regulations does not 
belong in a section devoted to disposal of excess spoil.
    We are not proposing to move the requirements of 30 CFR 817.71(k) 
to another part of our rules because we do not find it necessary to 
impose the design requirements for excess spoil fills (which are 
permanent structures) on temporary spoil storage structures and support 
facilities, such as the benches to which section 817.71(k) applies. Nor 
do we find it necessary or appropriate to limit those benches to 400 
feet in length. Bench length and configuration are more appropriately 
determined by operational, topographic, geologic, and other site-
specific considerations. However, the regulatory authority has the 
right to impose design and construction requirements on a case-by-case 
basis when it determines that those requirements are a necessary 
prerequisite to making the permit application approval findings 
specified in 30 CFR 773.15.
7. Section 817.102: How must I backfill surface excavations and grade 
and configure the land surface?
    This section contains several differences from proposed 30 CFR 
816.102 for surface mining activities. First, in paragraph (a), we 
propose to clarify that the backfilling requirement applies to surface 
excavations created by surface operations associated with underground 
mines.
    Second, the underground mining regulations would not include the 
exceptions for mountaintop removal mining and thin and thick overburden 
found in proposed 30 CFR 816.102(a)(1)(i), (iii), and (iv). Those 
provisions do not apply to underground mining operations.
    Third, we propose to move existing 30 CFR 817.102(l) to paragraph 
(a)(1)(vii) to consolidate it with the other exceptions to the 
requirement to restore the approximate original contour. We also 
propose to replace the word ``fills'' in the existing rule with ``spoil 
storage areas'' to comply more accurately with the decision in In re: 
Permanent Surface Mining Regulation Litigation I, Round II (PSMRL I, 
Round II) when read as a whole.\731\ The opinion directs the Secretary 
to provide some flexibility for underground mining operations with 
respect to regrading spoil from face-up areas. The court's opinion 
addresses the requirement to restore the approximate original contour 
for spoil stored until the underground mining operation is completed:

    \731\ See In re: Permanent Surface Mining Regulation Litigation 
I-Round II, No. 79-1144, 1980 U.S. Dist. LEXIS 17660 at *17-18 
(D.D.C. May 16, 1980).

    One distinct difference between surface and underground mines 
concerns the length of their duration. An underground mine may 
remain active up to 40 years. Surface disturbances thereby become 
settled and revegetated. In this situation, it is duplicitous to 
require the removal of previously settled and revegetated land only 
to achieve the purpose of a second revegetation. The court therefore 
remands these regulations. It directs the Secretary to provide some 
flexibility for settled fills that have become stabilized and 
revegetated.\732\
---------------------------------------------------------------------------

    \732\ Id. at *18.

    The opinion does use the word ``fills'' in one instance in the last 
sentence of the opinion. However, we do not believe that the court 
intended its opinion to address excess spoil because excess spoil by 
definition includes only spoil not needed to restore the approximate 
original contour, which means that excess spoil fills already are 
excluded from the requirement to restore the approximate original 
contour. Therefore, applying this exception only to excess spoil fills 
would render the court's decision meaningless.
    The court's decision does not discuss the requirement in section 
515(b)(3) of SMCRA \733\ to eliminate all highwalls. We do not 
interpret the court's decision as requiring an exception from that 
requirement. The court's objection to the 1979 rule discusses 
situations in which the only purpose of removing and regrading spoil in 
a settled and revegetated storage area would be to restore the 
approximate original contour to achieve a second revegetation. However, 
removal of the stored spoil may be necessary for purposes other than 
revegetation. For example, the stored spoil may be needed to eliminate 
the highwall at the mine face-up. Therefore, we propose to add 
paragraph (a)(1)(vii)(G) to specify that settled and revegetated spoil 
storage areas may not be retained undisturbed if the spoil in those 
areas is needed to eliminate the

[[Page 44578]]

highwall or to meet other requirements of the regulatory program.

8. Section 817.121: What measures must I take to prevent, control, or 
correct damage resulting from subsidence?
    We propose to revise paragraph (c)(4) of this section by removing 
those provisions that we suspended on December 22, 1999 (64 FR 71652-
71653), in response to a court order vacating those provisions.\734\ 
Specifically, we propose to remove all of existing 30 CFR 817.121(c)(4) 
except paragraph (c)(4)(v). We also propose to restructure this section 
for clarity and ease of reference and revise it in accordance with 
plain-language principles to make it more user-friendly. We do not 
propose any substantive revisions.

9. Why are we proposing to remove the interpretive rules in existing 30 
CFR 817.200?
    Existing 30 CFR 817.200 contains two interpretive rules. The first 
one, in paragraph (c), pertains to the 1979 version of the topsoil 
substitute requirements in 30 CFR 817.22. However, we subsequently 
revised 30 CFR 817.22 in a manner that rendered the interpretive rule 
obsolete.\735\ Therefore, we intend to remove existing 30 CFR 
817.200(c).
---------------------------------------------------------------------------

    \735\ See 48 FR 22100 (May 16, 1983).
---------------------------------------------------------------------------

    The second interpretive rule, in paragraph (d), addresses the use 
of the permit revision process for postmining land use changes for 
underground mines. We propose to include this interpretive rule into 30 
CFR 784.24 in revised form to the extent that it contains unique 
provisions not already present in other regulations. Specifically, 
proposed 30 CFR 784.24(c) would require that any proposed change to a 
higher or better postmining land use be processed as a significant 
permit revision. We will remove 30 CFR 817.200(d) if we adopt proposed 
30 CFR 784.24(c).
    As discussed in the preamble to proposed 30 CFR 780.24(c), we 
propose to apply this requirement only to changes to higher or better 
uses rather than to all proposed land use changes because we also 
propose to revise our postmining land use regulations to clarify that 
the standards and procedures for approving alternative postmining land 
uses would apply only to changes to higher or better uses.
    Changes from one land use that the land was capable of supporting 
prior to mining to another land use that the land was capable of 
supporting prior to mining would no longer require approval as an 
alternative postmining land use. Our proposed revisions would improve 
consistency with section 515(b)(2) of SMCRA,\736\ which requires that 
surface coal mining and reclamation operations ``restore the land 
affected to a condition capable of supporting the uses which it was 
capable of supporting prior to any mining, or higher or better uses of 
which there is a reasonable likelihood.'' The statutory provision 
distinguishes only between uses that the land was capable of supporting 
before mining and higher or better uses; i.e., it establishes criteria 
for approval of higher or better uses, but no special criteria for 
approval of any of the uses that the land was capable of supporting 
before mining.

N. Part 824: Special Permanent Program Performance Standards--
Mountaintop Removal Mining Operations

    We propose to revise 30 CFR 824.11(a) by removing paragraphs (a)(2) 
through (a)(4) because they duplicate our proposed definition of 
mountaintop removal mining in 30 CFR 701.5. In addition, we propose to 
streamline the introductory language by specifying that 30 CFR 824.11 
applies to all operations for which the regulatory authority has 
approved a permit under 30 CFR 785.14.
    Proposed paragraph (b)(1) would include existing 30 CFR 
824.11(a)(5), which provides that mountaintop removal mining operations 
must meet all applicable requirements of the regulatory program except 
for approximate original contour restoration requirements. We propose 
to revise this paragraph by adding a citation to the approximate 
original contour restoration requirements in proposed 30 CFR 
816.102(a)(1) and by adding an exception from the thick overburden 
requirements of 30 CFR 816.105. The latter requirements are 
inconsistent with the purpose of mountaintop removal mining operations, 
which is to create a level plateau or gently rolling contour, because 
the thick overburden rules require that as much spoil be returned to 
the mined-out area as possible.
    Under proposed paragraph (b)(2)(i), as under existing 30 CFR 
824.11(a)(6), the permittee would be required to retain an outcrop 
barrier, consisting of the toe of the lowest coal seam and its 
associated overburden, of sufficient width to prevent slides and 
erosion, except for certain specified exceptions. We propose to revise 
this provision to require that the permittee construct drains through 
the barrier to the extent necessary to prevent saturation of the 
backfill. This requirement is necessary because the outcrop barrier 
resembles a berm but consists of consolidated natural rock and coal 
that is much less permeable than the fractured, unconsolidated rock of 
which backfill is comprised. Without drains, the barrier could serve as 
a dike, impounding water in the void spaces within the backfill. 
Allowing the foundation zone of the backfill to become saturated could 
result in slope instability, which would be inconsistent with section 
102(a) of SMCRA,\737\ which states that one of the purposes of SMCRA is 
to ``establish a nationwide program to protect society and the 
environment from the adverse effects of surface coal mining 
operations.''
---------------------------------------------------------------------------

    \737\ 30 U.S.C. 1202(a).
---------------------------------------------------------------------------

    We also propose to add paragraph (b)(2)(iv) to allow the regulatory 
authority to approve removal of the outcrop barrier required by 
paragraph (b)(2)(i) if the regulatory program establishes standards for 
and requires construction of a barrier comprised of alternative 
materials that will provide equivalent stability. We have approved one 
such state program provision in West Virginia that has worked well, 
both in terms of stability and in terms of maximizing coal recovery 
consistent with section 515(b)(1) of SMCRA.\738\
---------------------------------------------------------------------------

    \738\ 30 U.S.C. 1265(b)(1).
---------------------------------------------------------------------------

    In proposed paragraph (b)(3), which would include existing 30 CFR 
824.11(a)(7), we propose to delete the phrase ``on the mined area'' 
from the language requiring final graded slopes to be no steeper than 
20 percent. This revision would allow the plateau area to extend 
outside the mined area to include the decks (top surfaces) of excess 
spoil fills, which would be consistent with the concept of mountaintop 
removal mining and could facilitate the use of landforming principles 
if desired.
    In proposed paragraph (b)(4), which would include existing 30 CFR 
824.11(a)(8), we propose to delete the existing sentence that prohibits 
directing drainage through or over a valley or head-of-hollow fill. 
This proposed revision would enhance the ability of the permittee to 
use landforming principles and natural stream channel design techniques 
when it is possible to do so without adversely impacting the stability 
of the fill and without increasing discharges of parameters of concern. 
Its adoption would allow the reestablishment or replacement of impacted 
or buried streams and facilitate the use of drainage techniques that 
incorporate the

[[Page 44579]]

best technology currently available for the control of drainage. In 
particular, it would allow the construction of stable channels to 
convey discharges and runoff from the plateau areas over valley and 
head-of-hollow fills.
    We propose to move existing 30 CFR 824.11(a)(9), which prohibits 
damage to natural watercourses below the lowest coal seam to be mined, 
to 30 CFR 785.14(b)(9) in revised form. We propose to do so because 
this requirement is really more of an operational design element 
(permitting requirement) than a performance standard, especially in 
view of our proposed interpretation of the meaning of the underlying 
statutory provision as discussed in the preamble to proposed 30 CFR 
785.14(b)(9).
    We propose to remove existing 30 CFR 824.11(a)(10), which requires 
that all waste and acid-forming and toxic-forming materials be covered 
with non-toxic spoil to prevent pollution and to achieve the postmining 
land use. As discussed above, this provision is unnecessary because it 
contains no requirements that are not already encompassed by proposed 
30 CFR 824.11(b)(1), which is the counterpart to existing 30 CFR 
824.11(a)(5).

O. Part 827: Special Permanent Program Performance Standards--Coal 
Preparation Plants Not Located Within the Permit Area of a Mine

    We propose to revise 30 CFR 827.12 by streamlining it to list only 
the sections of part 816 that apply to coal preparation plants not 
located at a mine. Specifically, this proposed rule would specify that 
the construction, operation, maintenance, modification, reclamation, 
and removal activities at coal preparation plants must comply with the 
following provisions of part 816: Sections 816.11, 816.22, 816.34 
through 816.57, 816.71, 816.74, 816.79, 816.81 through 816.97, 816.100, 
816.102, 816.104, 816.106, 816.111 through 816.116, 816.131 through 
816.133, 816.150, 816.151, and 816.181. This list of sections is 
substantively identical to the sections included in the existing rule, 
with the exception that we propose to add 30 CFR 816.57 to the list. 
Section 816.57 contains performance standards for mining in, through, 
or within 100 feet of perennial and intermittent streams.
    In a previous rulemaking, we declined to include 30 CFR 816.57, 
which at that time was known as the stream buffer zone rule, in 30 CFR 
827.12. However, we stated that we might add such a requirement ``in a 
separate rulemaking if experience under this rule indicates that such 
buffer zones are necessary to meet the Act's objectives.'' \739\
---------------------------------------------------------------------------

    \739\ 48 FR 20399 (May 5, 1983).
---------------------------------------------------------------------------

    Our experience over the last three decades has led us to propose 
inclusion of 30 CFR 816.57. Specifically, we find that coal preparation 
plants can have substantial and long-lasting adverse environmental 
impacts on streams as a result of dust, surface runoff, and 
noncompliant discharges of process water. In addition, coal preparation 
plants normally are in existence longer than a surface mine and some 
underground mines, which means that any impacts would be relatively 
long-term. An undisturbed buffer between coal preparation plants and 
streams could mitigate some of those impacts.

X. What effect would this rule have in federal program states and on 
Indian lands?

    If adopted in final form, the rule that we are proposing today 
would apply to all non-Indian lands in states with a federal regulatory 
program. States with federal regulatory programs include Arizona, 
California, Georgia, Idaho, Massachusetts, Michigan, North Carolina, 
Oregon, Rhode Island, South Dakota, Tennessee, and Washington. These 
programs are codified at 30 CFR parts 903, 905, 910, 912, 921, 922, 
933, 937, 939, 941, 942, and 947, respectively. In general, there would 
be no need to amend the approved federal program before the rule would 
take effect because, with limited exceptions, each program cross-
references 30 CFR parts 700, 701, 773, 774, 777, 779, 780, 783, 784, 
785, 800, 816, 817, 824, and 827.
    Tennessee is the only federal program state with active coal 
production and, thus, is the only state in which the rule would have 
immediate impact. Tennessee law already sharply restricts most 
significant mining activities in or near streams, which means that the 
provisions of proposed 30 CFR 780.28, 784.28, 816.57, and 817.57 
pertaining to mining in, through, or near streams, are unlikely to have 
a significant effect on mining within that state. Section 69-3-108(f) 
of the Tennessee Code Annotated, as amended by the Responsible Mining 
Act of 2009, prohibits issuance of any permit for the removal of coal 
by surface mining methods or for surface access points to underground 
mining within 100 feet of the ordinary high-water mark of a stream. It 
also prohibits issuance of a permit that would allow placement of 
overburden or waste from a surface mine within that buffer zone. 
However, unlike the proposed federal rule, the state law does not apply 
to any type of stream crossing, to operations that improve the quality 
of stream segments previously disturbed by mining, or to coal mine 
waste from underground mines or coal preparation plants. Nor does the 
state law apply to coal transportation, storage, preparation and 
processing, loading, and shipping operations when necessary because of 
site-specific conditions, provided that those activities and operations 
do not cause the loss of stream function.
    If adopted in final form, the following parts of the proposed rule 
that we are publishing today also would apply to Indian lands by virtue 
of cross-references in 30 CFR part 750:
     30 CFR 750.12(c)(1) includes the permitting provisions of 
parts 773, 774, 777, 779, 780, 783, 784, and 785 by cross-reference. We 
are not proposing any substantive revisions to the exceptions listed in 
30 CFR 750.12(c)(2).
     30 CFR 750.17 includes the bond and insurance provisions 
of subchapter J (part 800) by cross-reference.
     30 CFR 750.16 includes the performance standards of parts 
816, 817, 824, and 827 by cross-reference.
    The revisions to parts 700 and 701 also would apply to Indian lands 
by virtue of 30 CFR 700.1(a), which provides that subchapter A of 30 
CFR chapter VII contains ``regulatory requirements and definitions 
generally applicable to the programs and persons covered by the Act.''
    We invite the public to comment on whether there are unique 
conditions in any federal program states or on Indian lands that should 
be addressed in the national rule or as specific amendments to 
individual federal programs or to the Indian lands rules.

XI. How would this rule affect state regulatory programs?

    Adoption of this proposed rule as a final rule would not have any 
immediate effect on approved state regulatory programs. States would 
need to propose and adopt counterpart revisions to their regulations 
and other state program provisions and submit them for review by OSMRE 
and the public as a program amendment under 30 CFR 732.17. Under 30 CFR 
732.17(g)(9), no change to state law or regulations shall take effect 
for purposes of a state program until that change is approved by OSMRE 
as a program amendment.
    If we adopt a final rule based on this proposed rule, we will 
evaluate each state regulatory program approved under 30 CFR part 732 
and section 503

[[Page 44580]]

of the Act \740\ to determine whether any changes in the state program 
are necessary to maintain consistency with federal requirements. If we 
determine that a state program provision needs to be amended as a 
result of revisions to the corresponding federal rule, we will notify 
the state in accordance with 30 CFR 732.17(d).
---------------------------------------------------------------------------

    \740\ 30 U.S.C. 1253.
---------------------------------------------------------------------------

    Section 505(a) of the Act \741\ and 30 CFR 730.11(a) provide that 
SMCRA and federal regulations adopted under SMCRA do not supersede any 
state law or regulation unless that law or regulation is inconsistent 
with the Act or the federal regulations adopted under the Act. Section 
505(b) of the Act \742\ and 30 CFR 730.11(b) provide that we may not 
construe existing state laws and regulations, or state laws and 
regulations adopted in the future, as inconsistent with SMCRA or the 
federal regulations if these state laws and regulations either provide 
for more stringent land use and environmental controls and regulations 
or have no counterpart in the Act or the federal regulations.
---------------------------------------------------------------------------

    \741\ 30 U.S.C. 1255(a).
    \742\ 30 U.S.C. 1255(b).
---------------------------------------------------------------------------

    Under 30 CFR 732.15(a), each state regulatory program must provide 
for the state to carry out the provisions and meet the purposes of the 
Act and its implementing regulations. In addition, that rule requires 
that state laws and regulations be in accordance with the provisions of 
the Act and consistent with the federal regulations. As defined in 30 
CFR 730.5, ``consistent with'' and ``in accordance with'' mean that the 
state laws and regulations are no less stringent than, meet the minimum 
requirements of, and include all applicable provisions of the Act. The 
definition also provides that these terms mean that the state laws and 
regulations are no less effective than the federal regulations in 
meeting the requirements of the Act. Under 30 CFR 732.17(e)(1), we may 
require a state program amendment if, as a result of changes in SMCRA 
or the federal regulations, the approved state regulatory program no 
longer meets the requirements of SMCRA or the federal regulations.

XIII. Procedural Matters and Required Determinations

A. Regulatory Planning and Review (Executive Orders 12866 and 13563)

    Executive Order 12866 provides that the Office of Information and 
Regulatory

[[Page 44581]]

Affairs (OIRA) will review all significant rules. OIRA has determined 
that this proposed rule is significant because it may have an annual 
effect on the economy of $100 million or more, or adversely affect in a 
material way the economy, a sector of the economy, productivity, 
competition, jobs, the environment, public health, or safety, or State, 
local or tribal governments or communities.
    Executive Order 13563 reaffirms the principles of E.O. 12866 while 
calling for improvements in the Nation's regulatory system to promote 
predictability, to reduce uncertainty, and to use the best, most 
innovative, and least burdensome tools for achieving regulatory ends. 
The executive order directs agencies to consider regulatory approaches 
that reduce burdens and maintain flexibility and freedom of choice for 
the public where these approaches are relevant, feasible, and 
consistent with regulatory objectives. E.O. 13563 emphasizes further 
that regulations must be based on the best available science and that 
the rulemaking process must allow for public participation and an open 
exchange of ideas. We have developed this proposed rule in a manner 
consistent with these requirements.
    We have prepared a draft regulatory impact analysis (RIA) and 
submitted it to the Office of Management and Budget. We invite comments 
on that analysis, which you can view online at www.osmre.gov and 
www.regulations.gov or in person at the headquarters office location 
listed in ADDRESSES and at the OSMRE regional, field, and area office 
locations listed in Part XII of this preamble.
    Based upon the draft RIA, we do not project that the proposed rule 
would prohibit mining of any particular coal reserves in excess of 
baseline conditions. Therefore, our estimates do not include the direct 
and indirect costs associated with stranded coal reserves. We invite 
comment on the occurrence of stranded coal reserves as a consequence of 
the proposed rule and any attendant costs that should be included in 
the RIA.
    We also invite comment on the cost assumptions by model mine and 
alternative in Exhibit 4-3 in the draft RIA, including the assumed 
costs for habitat restoration.
Social Cost of Carbon (SCC)
    The Interagency Working Group on the Social Cost of Carbon issued 
guidelines in 2010, and an update in 2013, to help agencies assess the 
climate change-related benefits of reducing carbon emissions and 
integrate these estimates into their assessments of regulatory impacts 
in cost-benefit analyses.\743\ The Interagency Working Group guidance 
provides an SCC dollar value based on the average of three specific 
models. The SCC related to a specific proposed action is calculated by 
multiplying the change in emissions in that year by the SCC value 
appropriate for that year. The net present value of the benefits can be 
calculated by multiplying each of these future benefits by an 
appropriate discount factor and summing across all affected years.

    This analysis does not monetize the methane emissions and increased 
carbon sequestration effects of the action alternatives in the draft 
EIS for multiple reasons. Most fundamentally, data limitations prevent 
a quantitative analysis of the net effect of each alternative on carbon 
emissions from coal mining. Available evidence suggests that the 
alternatives would have varying offsetting effects on greenhouse gas 
emissions. For instance, some alternatives would result in changes that 
would increase emissions, such as an increase in the amount of time 
hauling vehicles are operated. Conversely, some of the same 
alternatives would increase the number of acres of forest reestablished 
or undisturbed annually, which would increase the carbon storage 
potential when compared to the No Action Alternative.
    Predicting the direction and magnitude of impacts on overall U.S. 
greenhouse gas emissions is highly complex. The impact depends on 
factors such as the change in coal prices, the technological 
flexibility that power producers have to switch to substitute fuels, 
the price trends for those substitutes, the emissions profile for those 
substitutes, changes in coal export markets, and a variety of other 
considerations.
    This analysis anticipates that the net effect on climate resiliency 
is positive at the national level under each action alternative 
(excluding Alternative 9), i.e., that each alternative would result in 
less carbon in the atmosphere because of increased carbon sequestration 
and reduced methane emissions. However, data gaps prevent quantifying, 
and therefore monetizing, the magnitude of this benefit.

B. Regulatory Flexibility Act (RFA).

    When a federal agency proposes regulations, the RFA, as amended by 
the Small Business Regulatory Enforcement Fairness Act of 1996 
(SBREFA), requires the agency to prepare and make available for public 
comment an analysis that describes the effect of the rule on small 
businesses, small organizations, and small government 
jurisdictions.\744\ For this rulemaking, the analysis takes the form of 
an Initial Regulatory Flexibility Analysis (IRFA), which appears in 
Appendix A of the draft regulatory impact analysis.

Estimate of the Number of Small Entities to Which the Rule Would Apply
    The goal of this analysis is to identify the number of small 
entities with mining permits that fall within each coal region. 
However, due to the complexity in corporate structures in the coal 
mining industry, it is difficult to calculate the exact number of small 
entities (defined by the RFA as having 500 or fewer employees) that 
could be affected by this proposed rule. The coal mining industry is 
continually changing and it is common for large mining operators to 
merge with smaller operators, creating complicated business 
relationships between parent corporations and subsidiaries.
    When determining how to estimate the number of small coal mining 
companies that could be affected by the proposed rule, we used a 
conservative approach to avoid underestimating the number of small 
entities. Specifically, we adhered to the method that the Mine Safety 
and Health Administration (MSHA) uses to calculate compliance costs to 
small business. MSHA examines the impact of a proposed rule on a mine 
with 500 or fewer employees, which is the Small Business Administration 
(SBA) threshold, and gives careful consideration to small mines with 
fewer than 20 employees. MSHA's rationale for applying these two 
thresholds is as follows:

    MSHA has also examined the impact of the proposed rule on mines 
with fewer than 20 employees, which MSHA and the mining community 
have traditionally referred to as ``small mines.'' These small mines 
differ from larger mines not only in the number of employees, but 
also in economies of scale in material produced, in the type and 
amount of production equipment, and in supply inventory. Therefore, 
their costs of complying with MSHA's rules and the impact of the 
Agency's rules on them would also tend to be different. This 
analysis complies with the requirements of the RFA for an analysis 
of the impact on ``small

[[Page 44582]]

entities'' while continuing MSHA's traditional definition of ``small 
mines.'' \745\

Preliminary Regulatory Economic Analysis for Lowering Miners' 
Exposure to Respirable Coal Mine Dust Including Continuous Personal 
Dust Monitors Proposed Rule. Washington, RIN 1219-AB64, September 
2010. Page 159.

    To estimate the number of small entities potentially affected by 
this rule, we used MSHA data from 2013 on mines, mine controllers, 
employees, and production to identify mines likely operated by small 
businesses. We assumed that each mine controller listed in that 
database represented a separate entity. We eliminated controllers with 
more than 500 employees. We also excluded all inactive mines, all 
operating companies reporting no employees, and all entities reporting 
less than 2,000 tons annual production because these mines are not 
representative of a typical small entity in the industry.
    We sorted small entities into those with identified controllers 
having 500 or fewer employees (the SBA threshold), and, as a subset, 
those controllers having fewer than 20 employees (the MSHA threshold). 
We determined that there were 284 small entities under the SBA 
threshold and 134 small entities under MSHA's small mine definition, 
with 91 percent of the SBA small entities and 96 percent of the MSHA 
small mines located in the Appalachian Basin.
    We estimate that compliance costs for SBA small entities would 
range between zero and 3.6 percent of gross annual revenues, depending 
on the mining region. In Appalachia, we estimate compliance costs would 
average 4.7 percent of gross annual revenues for surface mines and 2.5 
percent of gross annual revenues for underground mines.
    We estimate that compliance costs for MSHA small mines would range 
between 0 and 16 percent of gross annual revenues, depending on the 
mining region. In Appalachia, we estimate compliance costs would 
average 7.1 percent of gross annual revenues for surface mines and 4.3 
percent of gross annual revenues for underground mines.
Description of Measures to Minimize Economic Impacts on Small Entities
    Section 507(c) of SMCRA \746\ establishes the small operator 
assistance program (SOAP). To the extent that funds are appropriated 
for that program, this provision of SMCRA authorizes us to provide 
small operators with training and financial assistance in preparing 
certain elements of permit applications. An operator is eligible to 
receive training and assistance if his or her probable total annual 
production at all locations will not exceed 300,000 tons.
---------------------------------------------------------------------------

    \746\ 30 U.S.C. 1257(c).
---------------------------------------------------------------------------

    Under section 507(c)(1) of SMCRA \747\ and 30 CFR 795.9, the 
following permit application activities are eligible for financial 
assistance under SOAP:
---------------------------------------------------------------------------

    \747\ 30 U.S.C. 1257(c)(1).
---------------------------------------------------------------------------

     Preparation of the determination of the probable 
hydrologic consequences of mining, including collection and analysis of 
baseline data and any engineering analyses and designs needed for the 
determination.
     Collection and analysis of geological data.
     Development of cross-sections, maps, and plans.
     Collection of information on archaeological and historical 
resources and preparation of any related plans.
     Development of preblast surveys.
     Collection of site-specific information on fish and 
wildlife resources and preparation of fish and wildlife protection and 
enhancement plans.
    These activities include many of the new permit application 
requirements in the proposed rule; e.g., the expanded baseline data 
requirements concerning hydrology, geology, and the biological 
condition of streams and the expanded requirements for site-specific 
fish and wildlife protection and enhancement plans. In addition, 
section 507(c)(2) of SMCRA \748\ provides that, as part of SOAP, we 
must either provide training or assume the cost of training eligible 
small operators on the preparation of permit applications and 
compliance with the regulatory program. Although SOAP funding is 
available for activities associated with new permit application 
requirements and training, SMCRA does not authorize SOAP funding for 
compliance costs associated with the expanded requirements for 
monitoring groundwater, surface water, and the biological condition of 
streams.
---------------------------------------------------------------------------

    \748\ 30 U.S.C. 1257(c)(2).
---------------------------------------------------------------------------

    If this proposed rule is adopted as a final rule, we intend to 
interpret section 507(c)(1) of SMCRA \749\ in a manner that will 
maximize SOAP funding eligibility for the cost of compliance with the 
new permit application requirements. We invite comment on whether 30 
CFR 795.9 could or should be revised to include more of the new permit 
application requirements in this proposed rule.
---------------------------------------------------------------------------

    \749\ 30 U.S.C. 1257(c)(1).
---------------------------------------------------------------------------

    SOAP funding is subject to annual appropriation from the federal 
expense portion of the Abandoned Mine Reclamation Fund established 
under section 401(a) of SMCRA.\750\ Section 401(c)(9) of SMCRA \751\ 
caps SOAP funding at $10 million per year. If this proposed rule is 
adopted, we intend to request $10 million in appropriations to provide 
financial assistance to small operators in developing permit 
applications. We also intend to provide training to assist small 
operators in meeting the additional requirements of the proposed rule. 
Thus, SOAP assistance should substantially reduce compliance costs for 
small operators by offsetting the cost of most of the new permit 
application requirements.

C. Small Business Regulatory Enforcement Fairness Act

    This proposed rule is not a major rule under the Small Business 
Regulatory Enforcement Fairness Act, 5 U.S.C. 804(2). As discussed in 
the draft regulatory impact analysis, the proposed rule would not--
    a. Have an annual effect on the economy of $100 million or more.
    b. Cause a major increase in costs or prices for consumers; 
individual industries; federal, state, or local government agencies; or 
geographic regions.
    c. Have significant adverse effects on competition, employment, 
investment, productivity, innovation, or the ability of U.S.-based 
enterprises to compete with foreign-based enterprises.

D. Unfunded Mandates

    This proposed rule would not impose an unfunded mandate on state, 
local, or tribal governments or the private sector of $100 million or 
more per year. As discussed in the draft regulatory impact analysis, 
the total aggregate annual compliance and related costs associated with 
this proposed rule would not exceed $60 million. In addition, the 
proposed rule would not have a significant or unique effect on state, 
tribal, or local governments or the private sector. Therefore, a 
statement containing the information required by the Unfunded Mandates 
Reform Act, 2 U.S.C. 1534, is not required.

E. Executive Order 12630--Takings

    Under the criteria in Executive Order 12630, we have made a 
preliminary determination that this proposed rule does not have 
specific, identifiable takings implications. First, based upon the 
draft regulatory impact analysis, we

[[Page 44583]]

do not project that the proposed rule would prohibit mining of any 
particular coal reserves in excess of baseline conditions. Second, the 
question of whether the proposed rule might effect a compensable taking 
of a particular property interest necessarily involves ad hoc factual 
inquiries, including the economic impact of the proposed rule on a 
particular claimant; the extent to which the proposed rule might 
interfere with a claimant's reasonable, investment-backed expectations; 
and the character of the government action, none of which is possible 
for a national rule of this scope, which does not specifically bar the 
mining of any particular coal reserves. However, based upon the draft 
regulatory impact analysis, we have no basis to believe that 
implementation of the proposed rule would be likely to result in 
compensable takings of any specific property interests.

F. Executive Order 13132--Federalism

    This proposed rule would not alter or affect the relationship 
between states and the federal government. Therefore, the proposed rule 
does not have significant federalism implications. Consequently, there 
is no need to prepare a federalism assessment.

G. Executive Order 12988--Civil Justice Reform

    The Office of the Solicitor for the Department of the Interior has 
determined that this proposed rule would not unduly burden the judicial 
system and that it meets the requirements of sections 3(a) and 3(b)(2) 
of the Executive Order.

H. Executive Order 13175--Consultation and Coordination With Indian 
Tribal Governments

    We have evaluated the potential effects of this proposed rule on 
federally-recognized Indian tribes and have determined that its 
provisions would not have substantial direct effects on the 
relationship between the federal government and Indian tribes or on the 
distribution of power and responsibilities between the federal 
government and Indian tribes. On May 12, 2010, the Director of OSMRE 
met with the Chairmen of the Hopi and Crow Tribes and the President of 
the Navajo Nation to initiate consultation on the stream protection 
rulemaking and development of the draft EIS. The tribes in attendance 
requested that they be kept informed of the rulemaking process and EIS 
development. The Director of OSMRE again met with tribal leaders in 
Washington, DC on December 1, 2011. At that time, OSMRE provided 
additional information on the elements under consideration for the 
alternatives in the draft EIS and discussed the expected impacts to the 
SMCRA regulatory program for Indian lands. OSMRE intends to consult 
with tribal leaders again after the proposed rule has been published.

I. Executive Order 13211--Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use

    This proposed rule is not considered a significant energy action 
under Executive Order 13211. As discussed below and in the draft 
regulatory impact analysis, the revisions contained in this proposed 
rule would not have a significant effect on the supply, distribution, 
or use of energy.
    The Office of Management and Budget has identified nine outcomes 
that may constitute ``a significant adverse effect.'' The three 
outcomes that are relevant to this proposed rule are: (1) A reduction 
in coal production in excess of five million tons per year, (2) a 
reduction in electricity production in excess of one billion kilowatt-
hours per year or in excess of 500 megawatts (MW) of installed 
capacity,\752\ and (3) an increase in the cost of energy production in 
excess of one percent. As explained below, the proposed rule would not 
meet any of these criteria.
---------------------------------------------------------------------------

    \752\ Installed capacity is the ``total manufacturer-rated 
capacity for equipment such as turbines, generators, condensers, 
transformers, and other system components'' and represents the 
maximum flow of energy from the plant or the maximum output of the 
plant.
---------------------------------------------------------------------------

    The draft regulatory impact analysis estimates the impact of the 
proposed rule on coal production over a 21-year period, 2020 through 
2040. On average, the rule would reduce coal production by 1.9 million 
short tons per year, with the greatest impact occurring in 2022, when 
the reduction would be 4.6 million short tons.
    Because coal makes up a significant part of the domestic energy 
mix, an increase in the price of coal likely would result in an 
increase in domestic electricity prices, which in turn would reduce 
market demand for electricity. The draft regulatory impact analysis 
predicts that the proposed rule would increase electricity costs by 0.1 
percent per year on average, which would result in an average decrease 
in electricity demand and production of 0.2 billion kilowatt-hours per 
year.
    Compliance costs associated with the proposed rule would be less 
than one percent of total coal production costs in every year within 
the study period (2020-2040). On average, compliance costs would 
comprise 0.1 percent of total coal production costs over that period.

J. Paperwork Reduction Act

    Under 5 CFR 1320, the rules implementing the information collection 
aspects of the Paperwork Reduction Act, a federal agency must estimate 
the burden imposed on the public by any proposed collection of 
information. This burden consists of ``the total time, effort, or 
financial resources expended by persons to generate, maintain, retain, 
or disclose or provide information to or for a Federal agency.''
    We estimated the aggregate burden (in hours) for information 
collection under the proposed rule by calculating the number of hours 
that industry and state and local governments would need to comply with 
each element of the proposed rule.
    In addition, we estimated the total annual non-hour cost burden to 
respondents. These non-wage costs include items such as equipment 
required for monitoring, sampling, drilling and testing, operation and 
maintenance, and purchase of services.
    We calculated the total estimated burden for two respondent groups, 
mine operators and state regulatory authorities, on an annual basis 
averaged over a 3-year period.
Summary of Burden (Costs) Calculated for Major Elements of Stream 
Protection Rule
    This proposed rule contains collections of information that we are 
submitting to the Office of Management and Budget (OMB) for review and 
approval in accordance with the Paperwork Reduction Act, 44 U.S.C. 
3501, et seq. These collections are contained in 30 CFR parts 774, 779, 
783, 780, 784, 785, 800, 816, and 817. We also estimated programmatic 
changes where burden is being moved between parts.
    Title: 30 CFR part 774--Revision; Renewal; Transfer, Assignment, or 
Sale of Permit Rights; Post-Permit Issuance Requirements.
    OMB Control Number: 1029-xxx1.
    Summary: Sections 506, 507, 509, 510, and 511 of SMCRA provide that 
persons seeking permit revisions, permit renewals; or the transfer, 
assignment, or sale of their permit rights for coal mining activities 
submit relevant information to the regulatory authority to allow the 
regulatory authority to determine whether the applicant meets the 
requirements for the action requested.

    Title: 30 CFR parts 779 and 783--Surface and Underground Mining 
Permit Applications--Minimum Requirements for Information on 
Environmental Resources and Conditions.
    OMB Control Number: 1029-xxx2.
    Summary: Applications for surface and underground coal mining 
permits are required to provide adequate descriptions of the 
environmental resources that may be affected by proposed surface mining 
activities. Without this information, OSMRE and state regulatory 
authorities could not approve permit applications for surface coal 
mines and related facilities.
    Title: 30 CFR part 780--Surface Mining Permit Applications--Minimum 
Requirements for Operation and Reclamation Plans.
    OMB Control Number: 1029-xxx3.
    Summary: Sections 507 and 508 of the Act contain permit application 
requirements for surface coal mining activities, including a 
requirement that the application include an operation and reclamation 
plan. The regulatory authority uses this information to determine 
whether the proposed surface coal mining operation will achieve the 
environmental protection requirements of the Act and regulatory 
program. Without this information, OSMRE and state regulatory 
authorities could not approve permit applications for surface coal 
mines and related facilities.
    Title: 30 CFR part 784--Underground Mining Permit Applications--
Minimum Requirements for Operation and Reclamation Plans.
    OMB Control Number: 1029-xxx4.
    Summary: Sections 507(b), 508(a), and 516(b) and (d) of SMCRA 
require applicants for permits for underground coal mines to prepare 
and submit operation and reclamation plans for coal mining activities 
as part of the application. Regulatory authorities use this information 
to determine whether the plans will achieve the reclamation and 
environmental protection requirements of the Act and regulatory 
program. Without this information, OSMRE and state regulatory 
authorities could not approve permit applications for underground coal 
mines and related facilities.
    Title: 30 CFR part 785--Requirements for Permits for Special 
Categories of Mining.
    OMB Control Number: 1029-xxx5.
    Summary: Sections 507, 508, 510, 515, 701, and 711 of SMCRA require 
applicants for special categories of mining activities to provide 
descriptions, maps, plans and data relating to the proposed activity. 
Without this information, OSMRE and state regulatory authorities could 
not approve permit applications for special categories of mining 
activities.
    Title: 30 CFR part 800--Bond, Financial Assurance, and Insurance 
Requirements for Surface Coal Mining and Reclamation Operations Under 
Regulatory Programs.
    OMB Control Number: 1029-xxx6.
    Summary: OSMRE and state regulatory authorities use the information 
collected under 30 CFR part 800 to ensure that persons conducting or 
planning to conduct surface coal mining and reclamation operations post 
and maintain a performance bond or financial assurance in a form and 
amount adequate to guarantee fulfillment of all reclamation 
obligations.
    Title: 30 CFR parts 816 and 817--Permanent Program Performance 
Standards--Surface and Underground Mining Activities.
    OMB Control Number: 1029-xxx7.
    Summary: Sections 515 and 516 of SMCRA provide that permittees 
conducting coal mining and reclamation operations must meet all 
applicable performance standards of the regulatory program approved 
under the Act. The regulatory authority uses the information collected 
to assist in evaluating compliance with this requirement.
    The table below summarizes estimated information collection burdens 
associated with this proposed rule, should it become final. We 
calculated the total estimated burden for two respondent groups, mine 
operators and state regulatory authorities, on an annual basis averaged 
over a 3-year period. The table does not include operational or other 
costs that do not involve a collection of information.

the administrative record for this proposed rule at the location 
specified under ADDRESSES. You also may review the draft EIS at 
www.osmre.gov and www.regulations.gov. The Docket ID Number is OSM-
2010-0021. We will complete a final environmental impact statement with 
responses to all substantive comments received on the draft statement 
before we publish a final rule.

L. Data Quality Act

    In developing this proposed rule, we did not conduct or use a 
study, experiment, or survey requiring peer review under the Data 
Quality Act (Pub. L. 106-554).

M. 1 CFR Part 51--Incorporation by reference

    Proposed 30 CFR 780.25(a)(2)(i)(B), 784.25(a)(2)(i)(B), 
816.49(a)(1), and 817.49(a)(1) would incorporate by reference the 
Natural Resources Conservation Service publication ``Earth Dams and 
Reservoirs,'' Technical Release No. 60 (210-VI-TR60, July 2005) (``TR-
60''). The proposed incorporation by reference would replace the 
incorporation by reference of the now-obsolete October 1985 edition of 
TR-60 in the existing rules. While the incorporation by reference would 
extend to the entire document, our regulations use only two elements of 
the publication: the hazard classification system for dams and the 
freeboard hydrograph criteria for impoundments in the table entitled 
``Minimum Emergency Spillway Hydrologic Criteria.''
    Under 1 CFR 51.5(a), we must make the materials that we propose to 
incorporate by reference reasonably available to interested parties. 
The July 2005 edition of TR-60 is available for review and download 
free of charge from the Web site of the Natural Resources Conservation 
Service at https://www.info.usda.gov/scripts/lpsiis.dll/TR/TR_210_60.htm. The publication also is available for review in person 
at the OSMRE headquarters office location listed in ADDRESSES and at 
the OSMRE regional, field, and area office locations listed in Part XII 
of this preamble.

Sec.  700.11  What coal exploration and coal mining operations are 
subject to our rules?

* * * * *
    (d) Termination and reassertion of jurisdiction--(1) Termination of 
jurisdiction for initial regulatory program sites. A regulatory 
authority may terminate its jurisdiction under the initial regulatory 
program over a completed surface coal mining and reclamation operation, 
or portion thereof, when the regulatory authority determines in writing 
that all requirements imposed under subchapter B of this chapter have 
been successfully completed.
    (2) Termination of jurisdiction for permanent regulatory program 
sites. A regulatory authority may terminate its jurisdiction under the 
permanent regulatory program over a completed surface coal mining and 
reclamation operation, or portion thereof, when--
    (i) The regulatory authority determines in writing that all 
requirements imposed under the applicable regulatory program have been 
successfully completed; or
    (ii)(A) Where a performance bond or financial assurance was 
required, the regulatory authority has made a final decision in 
accordance with part 800 of this chapter to release the performance 
bond or financial assurance fully.
    (B) When a financial assurance has been posted under Sec.  800.18 
of this chapter and all other performance bonds posted for the site 
under part 800 of this chapter have been released, the regulatory 
authority may terminate jurisdiction over all portions of the site and 
all aspects of the operation except for treatment-related facilities 
and obligations covered by the financial assurance.
    (3) Reassertion of jurisdiction. Following a termination under 
paragraph (d)(1) or (2) of this section, the regulatory authority must 
reassert jurisdiction under the regulatory program over a site or 
operation if it is demonstrated that the written determination or bond 
release referred to in paragraph (d)(1) or (2) of this section was 
based upon fraud, collusion, or the intentional or unintentional 
misrepresentation of a material fact, which includes the discovery of a 
discharge requiring treatment of mining-related parameters of concern, 
as that term is defined in Sec.  701.5 of this chapter, after 
termination of jurisdiction.
    (4) Exception for certain underground mining requirements. The 
provisions of paragraphs (d)(1) and (2) of this section do not apply to

Sec.  701.5  Definitions

    Acid drainage or acid mine drainage means water with a pH of less 
than 6.0 and in which total acidity exceeds total alkalinity that is 
discharged from an active, inactive, or abandoned surface coal mining 
and reclamation operation or from an area affected by surface coal 
mining and reclamation operations.
* * * * *
    Adjacent area means--
    (a) Basic definition for all operations and all resources. The area 
outside the proposed or actual permit area within which there is a 
reasonable possibility of adverse impacts from surface coal mining 
operations or underground mining activities, as determined by the 
regulatory authority. The area covered by this term will vary with the 
context in which a regulation uses this term; i.e., the nature of the 
resource or resources addressed by a regulation in which the term 
``adjacent area'' appears will determine the size and other dimensions 
of the adjacent area for purposes of that regulation.
    (b) Underground mines. For underground mines, the adjacent area 
includes, at a minimum, the area overlying the underground workings 
plus the area within a reasonable angle of draw from the perimeter of 
the underground workings.
    (c) Underground mine pools. For all operations, the adjacent area 
also includes the area that might be affected physically or 
hydrologically by the dewatering of existing mine pools as part of 
surface or underground mining operations, plus the area that might be 
affected physically or hydrologically by mine pools that develop after 
cessation of mining activities.
* * * * *
    Approximate original contour means that surface configuration 
achieved by backfilling and grading of the mined area so that the 
reclaimed area closely resembles the general surface configuration of 
the land within the permit area prior to any mining activities or 
related disturbances and blends into and complements the

[[Page 44587]]

drainage pattern of the surrounding terrain. All highwalls and spoil 
piles must be eliminated to meet the terms of the definition, but that 
requirement does not prohibit the approval of terracing under Sec.  
816.102 or Sec.  817.102 of this chapter, the retention of access roads 
in accordance with Sec.  816.150 or Sec.  817.151 of this chapter, or 
the approval of permanent water impoundments that comply with 
Sec. Sec.  816.49, 816.56, and 780.24(b) or Sec. Sec.  817.49, 817.56, 
and 784.24(b) of this chapter. For purposes of this definition, the 
term ``mined area'' does not include excess spoil fills and coal refuse 
piles.
* * * * *
    Backfill, when used as a noun, means the spoil and waste materials 
used to fill the void resulting from an excavation created for the 
purpose of extracting coal from the earth. When used as a verb, the 
term refers to the process of filling that void. The term also includes 
all spoil and waste materials used to restore the approximate original 
contour.
    Bankfull means the water level, or stage, at which a stream, river, 
or lake is at the top of its banks and any further rise would result in 
water moving into the flood plain.
* * * * *
    Biological condition is a measure of the ecological health of a 
stream or segment of a stream as determined by the type, diversity, 
distribution, abundance, and physiological state of aquatic organisms 
and communities found in the stream or stream segment.
* * * * *
    Cumulative impact area means an area that includes the--
    (a) Actual or proposed permit area.
    (b) HUC-12 (U.S. Geological Survey 12-digit Watershed Boundary 
Dataset) watershed or watersheds in which the actual or proposed permit 
area is located.
    (c) Any other area within which impacts resulting from an actual or 
proposed surface or underground coal mining operation may interact with 
the impacts of all existing and anticipated surface and underground 
coal mining on surface-water and groundwater systems, including the 
impacts that existing and anticipated mining will have during mining 
and reclamation and after final bond release. At a minimum, existing 
and anticipated mining must include:
    (1) The proposed operation;
    (2) All existing surface and underground coal mining operations;
    (3) Any proposed surface or underground coal mining operation for 
which a permit application has been submitted to the regulatory 
authority;
    (4) Any proposed surface or underground coal mining operation for 
which a request for an authorization, certification, or permit has been 
submitted under the Clean Water Act;
    (5) All existing and proposed coal mining operations that are 
required to meet diligent development requirements for leased federal 
coal and for which a resource recovery and protection plan has been 
either approved or submitted to and reviewed by the authorized officer 
of the Bureau of Land Management under 43 CFR 3482.1(b); and
    (6) For underground mines, all areas of contiguous coal reserves 
adjacent to an existing or proposed underground mine that are owned or 
controlled by the applicant.
* * * * *
    Ecological function of a stream means the role that the stream 
plays in dissipating energy and transporting water, sediment, organic 
matter, and nutrients downstream. It also includes the ability of the 
stream ecosystem to retain and transform inorganic materials needed for 
biological processes into organic forms (forms containing carbon) and 
to oxidize those organic molecules back into elemental forms through 
respiration and decomposition. Finally, the term includes the role that 
the stream plays in the life cycles of plants, insects, amphibians 
(especially salamanders), reptiles, fish, birds, and mammals that 
either reside in the stream or depend upon it for habitat, 
reproduction, food, water, or protection from predators. The biological 
condition of a stream is one measure of its ecological function.
* * * * *
    Ephemeral stream means a stream or part of a stream that has 
flowing water only during, and for a short duration after, 
precipitation events in a typical year. Ephemeral streambeds are 
located above the water table year-round. Groundwater is not a source 
of water for streamflow. Runoff from rainfall is the primary source of 
water for streamflow.
* * * * *
    Excess spoil means spoil material disposed of in a location other 
than the mined-out area within the permit area and all spoil material 
placed above the approximate original contour within the mined-out area 
as part of the continued construction of an excess spoil fill with a 
toe located outside the mined-out area. This term does not include any 
spoil required and used to restore the approximate original contour of 
the mined-out area. Except as provided in the first sentence of this 
definition, this term does not include spoil material placed within the 
mined-out area in accordance with the thick overburden provisions of 
Sec.  816.105(b)(1) of this chapter. Nor does it include spoil material 
used to blend the mined-out area with the surrounding terrain in non-
steep slope areas in accordance with Sec.  816.102(b)(3) or Sec.  
817.102(b)(3) of this chapter.
* * * * *
    Fill means a permanent, non-impounding structure constructed under 
Sec. Sec.  816.71 through 816.83 or Sec. Sec.  817.71 through 817.83 of 
this chapter for the purpose of disposing of excess spoil or coal mine 
waste generated by surface coal mining operations or underground mining 
activities.
* * * * *
    Groundwater means subsurface water located in those portions of 
soils and geologic formations that are fully saturated with water; 
i.e., those zones where all the pore spaces and rock fractures are 
completely filled with water. This term includes subsurface water in 
both regional and perched aquifers, but it does not include water in 
soil horizons that are temporarily saturated by precipitation events.
* * * * *
    Hydrologic balance means the relationship between the quality and 
quantity of water inflow to, water outflow from, and water storage in a 
hydrologic unit such as a drainage basin, aquifer, soil zone, lake, or 
reservoir. It encompasses the dynamic relationships among 
precipitation, runoff, evaporation, and changes in storage of 
groundwater and surface water, as well as interactions that result in 
changes in the chemical composition or physical characteristics of 
groundwater and surface water, which may in turn affect the biological 
condition of streams and other water bodies.
* * * * *
    Intermittent stream means a stream or part of a stream that has 
flowing water during certain times of the year when groundwater 
provides water for streamflow. During dry periods, intermittent streams 
may not have flowing water. Runoff from rainfall is a supplemental 
source of water for streamflow.
* * * * *
    Land use means specific uses or management-related activities, 
rather than the vegetation or cover of the land. The term includes 
support facilities that are an integral part of the use. Land uses may 
be identified in combination when joint or seasonal uses occur. For 
purposes of this chapter, the following land use categories apply:

[[Page 44588]]

    (a) Cropland. Land used for the production of crops for harvest, 
either alone or in rotation with grasses and legumes. Crops include row 
crops, small grains, hay, commercial nursery plantings, vegetables, 
fruits, nuts, crops, and other plants typically cultivated for 
commercial purposes in fields, orchards, vineyards, and similar 
settings.
* * * * *
    Material damage, in the context of Sec. Sec.  784.30 and 817.121 of 
this chapter, means:
    (a) Any functional impairment of surface lands, features, 
structures or facilities;
    (b) Any physical change that has a significant adverse impact on 
the affected land's capability to support any current or reasonably 
foreseeable uses or causes significant loss in production or income; or
    (c) Any significant change in the condition, appearance or utility 
of any structure or facility from its pre-subsidence condition.
    Material damage to the hydrologic balance outside the permit area 
means any adverse impact from surface coal mining and reclamation 
operations or from underground mining activities, including any adverse 
impacts from subsidence that may occur as a result of underground 
mining activities, on the quality or quantity of surface water or 
groundwater, or on the biological condition of a perennial or 
intermittent stream, that would--
    (a) Preclude any designated use under sections 101(a) or 303(c) of 
the Clean Water Act or any existing or reasonably foreseeable use of 
surface water or groundwater outside the permit area; or
    (b) Impact threatened or endangered species, or have an adverse 
effect on designated critical habitat, outside the permit area in 
violation of the Endangered Species Act of 1973, 16 U.S.C. 1531 et seq.
* * * * *
    Mountaintop removal mining means surface mining activities in which 
the mining operation extracts an entire coal seam or seams running 
through the upper fraction of a mountain, ridge, or hill, except for 
outcrop barriers retained under Sec.  824.11(b)(2) of this chapter, by 
removing substantially all overburden above the coal seam and using 
that overburden to create a level plateau or a gently rolling contour, 
with no highwalls remaining, that is capable of supporting one or more 
of the postmining land uses identified in Sec.  785.14 of this chapter.
* * * * *
    Occupied residential dwelling and structures related thereto means, 
for purposes of Sec. Sec.  784.30 and 817.121 of this chapter, any 
building or other structure that, at the time the subsidence occurs, is 
used either temporarily, occasionally, seasonally, or permanently for 
human habitation. This term also includes any building, structure, or 
facility installed on, above, or below the land surface if that 
building, structure, or facility is adjunct to or used in connection 
with an occupied residential dwelling. Examples of such structures 
include, but are not limited to, garages; storage sheds and barns; 
greenhouses and related buildings; utilities and cables; fences and 
other enclosures; retaining walls; paved or improved patios, walks and 
driveways; septic sewage treatment facilities; and lot drainage and 
lawn and garden irrigation systems. This term does not include any 
structure used only for commercial agricultural, industrial, retail or 
other commercial purposes.
* * * * *
    Parameters of concern means those chemical or physical 
characteristics and properties of surface water or groundwater that 
could be altered by surface or underground mining activities, including 
discharges associated with those activities, in a manner that would 
adversely impact surface-water or groundwater quality or the biological 
condition of a stream.
    Perennial stream means a stream or part of a stream that has 
flowing water year-round during a typical year. The water table is 
located above the streambed for most of the year. Groundwater is the 
primary source of water for streamflow. Runoff from rainfall is a 
supplemental source of water for streamflow.
* * * * *
    Reclamation means those actions taken to restore mined land and 
associated disturbed areas to a condition in which the site is capable 
of supporting the uses it was capable of supporting prior to any mining 
or any higher or better uses approved by the regulatory authority. The 
site also must meet all other requirements of the permit and regulatory 
program that pertain to restoration of the site. For sites with 
discharges that require treatment, this term also includes those 
actions taken to eliminate, remediate, or treat those discharges, 
including both discharges from the mined area and all other discharges 
that are hydrologically connected to either the mined area or the 
operation, regardless of whether those discharges are located within 
the disturbed area.
    Reclamation plan means the plan for reclamation of surface coal 
mining operations under parts 780, 784, and 785 of this chapter.
* * * * *
    Renewable resource lands means aquifers, aquifer recharge areas, 
recharge areas for other subsurface and surface water, areas for 
agricultural or silvicultural production of food and fiber, and grazing 
lands.
    Replacement of water supply means, with respect to protected water 
supplies contaminated, diminished, or interrupted by coal mining 
operations, provision of water supply on both a temporary and permanent 
basis equivalent to premining quantity and quality. Replacement 
includes provision of an equivalent water delivery system and payment 
of operation and maintenance costs in excess of customary and 
reasonable delivery costs for premining water supplies.
* * * * *
    Temporary diversion means a channel constructed to convey 
streamflow or overland flow away from the site of actual or proposed 
coal exploration or surface coal mining and reclamation operations or 
to convey those flows to a siltation structure or other treatment 
facility. The term includes only those channels not approved by the 
regulatory authority to remain after reclamation as part of the 
approved postmining land use.
* * * * *
    Waters of the United States has the same meaning as the definition 
of that term in 40 CFR 230.3(s).
* * * * *

7. Revise Sec.  773.7 to read as follows:


Sec.  773.7  How and when will the regulatory authority review and make 
a decision on an application for a permit, permit revision, or permit 
renewal?

    (a) General. The regulatory authority will review an application 
for a permit, permit revision, or permit renewal; and issue a written 
decision granting, requiring modification of, or denying the 
application. Before making this decision, the regulatory authority must 
consider any written comments and objections submitted, as well as the 
records of any informal conference or hearing held on the application.
    (b) When will the regulatory authority make a decision on a permit 
application? (1) If an informal conference is held under Sec.  773.6(c) 
of this part, the regulatory authority will issue a decision on the 
application within 60 days of the close of the conference.
    (2) If no informal conference is held under Sec.  773.6(c) of this 
part, the regulatory authority must issue a decision on the application 
within a reasonable time established in the regulatory program. In 
determining what constitutes a reasonable time or times, the regulatory 
authority must consider the following five factors:
    (i) The time needed for proper site investigations.
    (ii) The complexity of the permit application.
    (iii) Whether there are any written objections on file.
    (iv) Whether the application previously has been approved or 
disapproved, in whole or in part.
    (v) The time required for coordination of permitting activities 
with other agencies under Sec.  773.5 of this part.
    (c) Who has the burden of proof? You, the applicant for a permit, 
revision of a permit, or the transfer, assignment, or sale of permit 
rights, have the burden of establishing that your application is in 
compliance with all requirements of the regulatory program.

8. Revise Sec.  773.15 to read as follows:


Sec.  773.15  What findings must the regulatory authority make before 
approving a permit application?

    The regulatory authority may not approve any application for a 
permit or a significant revision of a permit that you, the applicant, 
submit unless the application affirmatively demonstrates and the 
regulatory authority finds, in writing, on the basis of information set 
forth in the application or from information otherwise available that 
is documented in the approval, that--
    (a) The application is accurate and complete and you have complied 
with all applicable requirements of the Act and the regulatory program.
    (b) You have demonstrated that reclamation as required by the Act 
and the regulatory program can be accomplished under the reclamation 
plan contained in the permit application.
    (c) The proposed permit area is not within an area--
    (1) Under study or administrative proceedings under a petition 
filed pursuant to part 764 or part 769 of this chapter to have an area 
designated as unsuitable for surface coal mining operations, unless you 
demonstrate that you made substantial legal and financial commitments 
before January 4, 1977, in relation to the operation covered by the 
permit application;
    (2) Designated under parts 762 and 764 or 769 of this chapter as 
unsuitable for the type of surface coal mining operations that you 
propose to conduct; or
    (3) Subject to the prohibitions of Sec.  761.11 of this chapter, 
unless one or more of the exceptions provided under that section apply.
    (d) For mining operations where the private mineral estate to be 
mined has been severed from the private surface estate, you have 
submitted to the regulatory authority the documentation required under 
Sec.  778.15(b) of this chapter.
    (e) The regulatory authority has--
    (1) Made an assessment of the probable cumulative impacts of all 
anticipated coal mining on the hydrologic balance in the cumulative 
impact area;
    (2) Determined that the proposed operation has been designed to 
prevent material damage to the hydrologic balance outside the permit 
area; and
    (3) Inserted into the permit criteria defining material damage to 
the hydrologic balance outside the permit area on a site-specific 
basis, expressed in numerical terms for each parameter of concern, as 
required by Sec.  780.21(b) or Sec.  784.21(b) of this chapter.
    (f) You have demonstrated that any existing structure will comply 
with Sec.  701.11(d) of this chapter and the applicable performance 
standards of subchapter B or K of this chapter.
    (g) You have paid all reclamation fees from previous and existing 
operations as required by subchapter R of this chapter.
    (h) You have satisfied the applicable requirements of part 785 of 
this chapter.
    (i) If applicable, you have satisfied the requirements for approval 
of a long-term, intensive agricultural postmining land use.
    (j) The operation is not likely to jeopardize the continued 
existence of species listed or proposed for listing as threatened or 
endangered under the Endangered Species Act of 1973, 16 U.S.C. 1531 et 
seq., or result in destruction or adverse modification of designated 
critical habitat under that law.
    (k) The regulatory authority has taken into account the effect of 
the proposed permitting action on properties listed on and eligible for 
listing on the National Register of Historic Places. This finding may 
be supported in part by inclusion of appropriate permit conditions or 
changes in the operation plan protecting historic resources or a 
documented decision that the regulatory authority has determined that 
no additional protection measures are necessary.
    (l) For a proposed remining operation where you intend to reclaim 
in accordance with the requirements of Sec.  816.106 or Sec.  817.106 
of this chapter, the site of the operation is a previously mined area, 
as that term is defined in Sec.  701.5 of this chapter.
    (m) You are eligible to receive a permit, based on the reviews 
under Sec. Sec.  773.7 through 773.14 of this part.
    (n) You have demonstrated that--
    (1) The operation has been designed to prevent the formation of 
discharges with levels of parameters of concern that would require 
long-term treatment after mining has been completed.

[[Page 44590]]

    (2) There is no credible evidence that the design of the proposed 
operation will not work as intended to prevent the formation of 
discharges with levels of parameters of concern that would require 
long-term treatment after mining has been completed.
    (o) To the extent possible using the best technology currently 
available, the proposed operation has been designed to minimize 
disturbances and adverse impacts on fish, wildlife, and related 
environmental values, as identified in Sec.  779.20 or Sec.  783.20 of 
this chapter, and to achieve enhancement of those resources where 
practicable, as required under Sec.  780.16 or Sec.  784.16 of this 
chapter.

when the inspection is in response to an alleged violation reported to 
the regulatory authority by the private person.
    (e) You must take all possible steps to minimize any adverse impact 
to the environment or public health and safety resulting from 
noncompliance with any term or condition or the permit, including, but 
not limited to--
    (1) Any accelerated or additional monitoring necessary to determine 
the nature and extent of noncompliance and the results of the 
noncompliance.
    (2) Immediate implementation of measures necessary to comply.

Sec.  774.15  How may I renew a permit?

    (a) Right of renewal. A valid permit, issued pursuant to an 
approved regulatory program, carries with it the right of successive 
renewal, within the approved boundaries of the existing permit, upon 
expiration of the term of the permit.
    (b) Application requirements and procedures. (1) You, the 
permittee, must file an application for renewal of a permit with the 
regulatory authority at least 120 days before expiration of the 
existing permit term.
    (2) You must file the application for renewal in the form required 
by the regulatory authority. At a minimum, your application must 
include the following information--
    (i) Your name and address
    (ii) The term of the renewal requested.
    (iii) The permit number or other identifier.
    (iv) Evidence that a liability insurance policy for the operation 
will continue in full force and effect during the proposed renewal term 
or that you will have adequate self-insurance under Sec.  800.60 of 
this chapter for the proposed term of renewal.
    (v) Evidence that the performance bond for the permit will continue 
in full force and effect for the proposed term of renewal.
    (vi) A copy of the newspaper notice and proof of publication, as 
required by Sec.  778.21 of this chapter.
    (vii) An analysis of the monitoring results under Sec. Sec.  816.35 
through 816.37 or Sec. Sec.  817.35 through 817.37 of this chapter and 
an evaluation of the accuracy and adequacy of the determination of the 
probable hydrologic consequences of mining prepared under Sec.  780.20 
or Sec.  784.20 of this chapter.
    (viii) An update of the determination of the probable hydrologic 
consequences of mining prepared under Sec.  780.20 or Sec.  784.20 of 
this chapter, if needed, or documentation that the findings in the 
existing determination are still valid.
    (ix) Additional revised or updated information required by the 
regulatory authority.
    (3) Applications for renewal are subject to the public notification 
and public participation requirements in Sec. Sec.  773.6 and 773.19(b) 
of this chapter.
    (4) If an application for renewal includes any proposed revisions 
to the permit, those revisions must be identified and processed in 
accordance with Sec.  774.13 of this part.
    (c) Approval process--(1) Criteria for approval. The regulatory 
authority must approve a complete and accurate application for permit 
renewal, unless it finds, in writing that--
    (i) The terms and conditions of the existing permit are not being 
satisfactorily met.
    (ii) The present surface coal mining and reclamation operations are 
not in compliance with the environmental protection standards of the 
Act and the regulatory program. The permit eligibility standards in 
Sec. Sec.  773.12 through 773.14 of this chapter apply to this 
determination.
    (iii) The requested renewal substantially jeopardizes your 
continuing ability to comply with the Act and the regulatory program on 
existing permit areas.
    (iv) You have not provided evidence of having continuing liability 
insurance or self-insurance coverage as required under Sec.  800.60 of 
this chapter.
    (v) You have not provided evidence that any performance bond 
required to be in effect for the operation will continue in full force 
and effect for the proposed term of renewal.
    (vi) You have not posted any additional bond required by the 
regulatory authority under part 800 of this chapter.
    (vii) You have not provided any additional revised or updated 
information required by the regulatory authority.
    (viii) The finding that the regulatory authority made under Sec.  
773.15(e) of this chapter that the operation is designed to prevent 
material damage to the hydrologic balance outside the permit area is no 
longer accurate, as demonstrated by analysis of the monitoring results 
under Sec. Sec.  816.35 through 816.37 or Sec. Sec.  817.35 through 
817.37 of this chapter or the updated determination of the probable 
hydrologic consequences of mining prepared under paragraph (b)(2)(viii) 
of this section.
    (2) Burden of proof. In the determination of whether to approve or 
deny an application for renewal of a permit, the burden of proof is on 
the opponents of renewal.
    (3) Alluvial valley floor variance. Areas previously identified in 
the reclamation plan for the original permit as exempt from the 
standards in paragraphs (A) and (B) of section 510(b)(5) of the Act and 
the requirements of paragraphs (c) through (e) of Sec.  785.19 of this 
chapter will retain their exempt status for the term of the renewal.
    (d) Renewal term. The term for any permit renewal must not exceed 
the original permit term under Sec.  773.19(c) of this chapter.
    (e) Notice of decision. The regulatory authority must send copies 
of its decision to the applicant, to each person who filed comments or 
objections on the renewal, to each party to any informal conference 
held on the permit renewal, and to OSMRE if OSMRE is not the regulatory 
authority.
    (f) Administrative and judicial review. Any person having an 
interest which is or may be adversely affected by the decision of the 
regulatory authority has the right to administrative and judicial 
review under part 775 of this chapter.

plans developed in accordance with that law.
    (c) Protection of other species. You must describe how, to the 
extent possible using the best technology currently available, you will 
minimize disturbances and adverse impacts on fish, wildlife, and 
related environmental values. At a minimum, you must explain how you 
will--
    (1) Time operations to avoid or minimize disruption of critical 
life cycle events for fish and wildlife, including migration, nesting, 
breeding, calving, and spawning.
    (2) Retain forest cover and other native vegetation as long as 
possible and time the removal of that vegetation to minimize adverse 
impacts on aquatic and terrestrial species.
    (3) To the extent possible, maintain an intact forested buffer at 
least 100 feet wide between surface disturbances and perennial and 
intermittent streams that are located in forested areas. The buffer 
width must be measured horizontally on a line perpendicular to the 
stream beginning at the bankfull elevation or, if there are no 
discernible banks, the centerline of the active channel.

promote or do not inhibit the long-term development of wildlife 
habitat.
    (7) Avoid mining through perennial or intermittent streams or 
disturbing riparian habitat adjacent to those streams. When avoidance 
is not possible, minimize--
    (i) The time during which mining and reclamation operations disrupt 
those streams or associated riparian habitat;

describe how you will use the best technology currently available to 
enhance fish, wildlife, and related environmental values both within 
and outside the area to be disturbed by mining activities, where 
practicable. Your permit application must either identify and describe 
the enhancement measures that you will implement, where practicable, or 
explain why implementation of those measures is not practicable. 
Potential enhancement measures include, but are not limited to--
    (i) Using the backfilling and grading process to create postmining 
surface features and configurations, such as functional wetlands, of 
high value to fish and wildlife.
    (ii) Designing and constructing permanent impoundments in a manner 
that will maximize their value to fish and wildlife.
    (iii) Creating rock piles and other permanent landscape features of 
value to raptors and other wildlife for nesting and shelter, to the 
extent that those features are consistent with premining features, the 
surrounding topography, and the approved postmining land use.
    (iv) Reestablishing native forests or other native plant 
communities, both within and outside the permit area. This may include 
restoring the native plant communities that existed before any mining, 
establishing native plant communities consistent with the native plant 
communities that are a part of the natural succession process, or 
establishing native plant communities that will support wildlife 
species of local, state, or national concern, including, but not 
limited to, species listed or proposed for listing as threatened or 
endangered on a state or national level.
    (v) Establishing a vegetative corridor at least 100 feet wide along 
the banks of streams that lacked a buffer of this nature before mining. 
The corridor width should be measured horizontally on a line 
perpendicular to the stream beginning at the bankfull elevation or, if 
there are no discernible banks, the centerline of the active channel. 
Species selected for planting within the corridor must be comprised of 
species native to the area, including native plants adapted to and 
suitable for planting in riparian zones within the corridor. Whenever 
possible, you should establish this corridor along both banks of the 
stream.
    (vi) Implementing conservation practices identified in 
publications, such as the technical guides published by the Natural 
Resources Conservation Service.
    (vii) Permanently fencing livestock away from streams.
    (viii) Installing perches and nest boxes.
    (ix) Establishing conservation easements or deed restrictions, with 
an emphasis on preserving riparian vegetation and forested corridors 
along perennial and intermittent streams.

anticipated long-term adverse impacts. (i) Your permit application must 
identify and describe the enhancement measures under paragraph (d)(1) 
of this

[[Page 44600]]

section that you will implement if your surface mining activities would 
result in the long-term loss of native forest, other native plant 
communities, or a segment of a perennial or intermittent stream.
    (ii) The scope of the enhancement measures that you propose under 
paragraph (d)(2)(i) of this section must be commensurate with the 
magnitude of the long-term adverse impacts of the proposed operation. 
Whenever possible, the measures must be permanent.
    (iii)(A) Enhancement measures proposed under paragraph (d)(2) of 
this section must be implemented within the watershed in which the 
proposed operation is located, unless opportunities for enhancement are 
not available within that watershed. In that case, you must propose to 
implement enhancement measures in the closest adjacent watershed in 
which enhancement opportunities exist, as approved by the regulatory 
authority.
    (B) Each regulatory program must prescribe the size of the 
watershed for purposes of paragraph (d)(2)(iii)(A) of this section, 
using a generally-accepted watershed classification system.
    (iv) The permit approved by the regulatory authority must include a 
condition requiring completion of the enhancement measures proposed 
under paragraph (d)(2) of this section.
    (3) Inclusion within permit area. If the enhancement measures to be 
implemented under paragraphs (d)(1) and (2) of this section would 
involve more than a de minimis disturbance of the surface of land 
outside the area to be mined, you must include the land to be disturbed 
by those measures within the proposed permit area.
    (e) Fish and Wildlife Service review. (1)(i) The regulatory 
authority must provide the protection and enhancement plan developed 
under this section to the applicable regional or field office of the 
U.S. Fish and Wildlife Service whenever the resource information 
submitted under Sec.  779.20 of this chapter includes species listed as 
threatened or endangered under the Endangered Species Act of 1973, 16 
U.S.C. 1531 et seq., critical habitat designated under that law, or 
species proposed for listing as threatened or endangered under that 
law. The regulatory authority must provide the protection and 
enhancement plan to the Service no later than the time that it provides 
written notice of the permit application to the Service under Sec.  
773.6(a)(3)(ii) of this chapter.
    (ii) When the resource information obtained under Sec.  779.20 of 
this chapter does not include threatened or endangered species, 
designated critical habitat, or species proposed for listing as 
threatened or endangered, the regulatory authority must provide the 
protection and enhancement plan to the applicable regional or field 
office of the U.S. Fish and Wildlife Service only if the Service 
requests an opportunity to review and comment on that plan. The 
regulatory authority must provide the requested plan to the Service 
within 10 days of receipt of the request from the Service.
    (2)(i) The regulatory authority must document its disposition of 
all comments from the Service that pertain to fish and wildlife or 
plants listed as threatened or endangered under the Endangered Species 
Act of 1973, 16 U.S.C. 1531 et seq., or to critical habitat designated 
under that law.
    (ii) If the regulatory authority does not agree with a species-
specific protection measure or any other recommendation from the 
Service that pertains to fish and wildlife or plants listed as 
threatened or endangered under the Endangered Species Act of 1973, 16 
U.S.C. 1531 et seq., or to critical habitat designated under that law, 
the regulatory authority must explain the rationale for that decision 
in the disposition document prepared under paragraph (e)(2)(i) of this 
section. The regulatory authority must provide a copy of that document 
to the pertinent Service field office and OSMRE field office and must 
refrain from approving the permit application.
    (iii) If the Service field office does not concur with the 
regulatory authority's decision under paragraph (e)(2)(ii) of this 
section and the regulatory authority and the Service field office are 
unable to reach agreement at that level, either the regulatory 
authority or the Service may elevate the issue through the chain of 
command of the regulatory authority, the Service, and OSMRE for 
resolution.
    (iv) The regulatory authority may not approve the permit 
application until all issues are resolved in accordance with paragraph 
(e)(2)(iii) of this section and the regulatory authority receives 
written documentation from the Service that all issues have been 
resolved.

section at equally spaced monthly intervals for a minimum of 12 
consecutive months.
    (iv) The regulatory authority must extend the minimum data 
collection period specified in paragraphs (c)(4)(ii) and (iii) of this 
section whenever data available from the National Oceanic and 
Atmospheric Administration or similar databases indicate that the 
region in which the proposed operation is located experienced severe 
drought (-3.0 or lower on the Palmer Drought Severity Index) or 
abnormally high precipitation (3.0 or higher on the Palmer Drought 
Severity Index) during the initial baseline data collection period. 
Baseline data collection must continue until the dataset includes 12 
consecutive months without severe drought or abnormally high 
precipitation.
    (5) Precipitation measurements. You must provide records of 
precipitation amounts for the proposed permit area, using on-site, 
self-recording devices. Precipitation records must be adequate to 
generate and calibrate a hydrologic model of the site. The regulatory 
authority will determine whether you must create such a model.

those stream segments, if applicable.
    (d) Additional information for discharges from previous coal mining 
operations. If the proposed permit and adjacent areas contain any 
discharges from previous surface or underground coal mining operations, 
you must sample those discharges during low-flow conditions of the 
receiving stream on a one-time basis and analyze the samples for the 
parameters listed in paragraph (c)(2) of this section and for both

bioassessment protocol approved by the state or tribal agency 
responsible for preparing the water quality inventory required under 
section 305(b) of the Clean Water Act, or other scientifically-valid 
multimetric bioassessment protocol used by agencies responsible for 
implementing the Clean Water Act, modified as necessary to meet the 
following requirements. At a minimum, the protocol must--
    (i) Be based upon the measurement of an appropriate array of 
aquatic organisms, including identification of benthic 
macroinvertebrates to the genus level.
    (ii) Result in the calculation of index values for both habitat and 
macroinvertebrates.
    (iii) Provide a correlation of index values to the capability of 
the stream to support designated uses under section 101(a) or 303(c) of 
the Clean Water Act, as well as any other existing or reasonably 
foreseeable uses.
    (f) Geologic information. (1) Your application must include a 
description of the geology of the proposed permit and adjacent areas 
down to and including the deeper of either the stratum immediately 
below the lowest coal seam to be mined or any aquifer below the lowest

must be based on all of the following--
    (i) The cross-sections, maps, and plans required by Sec.  779.24 of 
this chapter.
    (ii) The information obtained under paragraphs (f)(3) and (f)(4) of 
this section.
    (iii) Geologic literature and practices.
    (3) For any portion of the proposed permit area in which the strata 
down to the coal seam or seams to be mined will be removed or are 
already exposed, you must collect and analyze samples collected from 
test borings; drill cores; or fresh, unweathered, uncontaminated 
samples from rock outcrops, down to and including the deeper of either 
the stratum immediately below the lowest coal seam to be mined or any 
aquifer below the lowest seam to be mined that may be adversely 
impacted by mining. Your application must include the following data 
and analyses:
    (i) Logs showing the lithologic characteristics, including physical 
properties and thickness of each stratum, and the location of any 
groundwater encountered.
    (ii) Chemical analyses identifying those strata that may contain 
acid-forming materials, toxic-forming materials, or alkalinity-
producing materials and the extent to which each stratum contains those 
materials.
    (iii) Chemical analyses of the coal seam for acid-forming or toxic-
forming materials, including, but not limited to, total sulfur and 
pyritic sulfur.
    (4) You must provide any additional geologic information and 
analyses that the regulatory authority determines to be necessary to 
protect the hydrologic balance or to meet the performance standards of 
this chapter.
    (5) You may request the regulatory authority to waive the 
requirements of paragraph (f)(3) of this section, in whole or in part. 
The regulatory authority may grant the waiver request only after 
finding in writing that the collection and analysis of such data is 
unnecessary because other representative information is available to 
the regulatory authority in a satisfactory form.
    (g) Cumulative impact area information. (1) The regulatory 
authority will obtain the hydrologic, geologic, and biological 
information necessary to assess the probable cumulative hydrologic 
impacts of the proposed operation and all anticipated mining on 
surface-water and groundwater systems in the cumulative impact area, as 
required by Sec.  780.21 of this part, from the appropriate federal or 
state agencies, to the extent that the information is available from 
those agencies.
    (2) If the information identified in paragraph (g)(1) of this 
section is not available from other federal or state agencies, you must 
gather and submit this information to the regulatory authority as part 
of the permit application before the regulatory authority may approve 
your application. As an alternative to collecting new information, you 
may submit data and analyses from nearby mining operations if the site 
of those operations is

[[Page 44603]]

representative of the proposed operations in terms of topography, 
hydrology, geology, geochemistry, and method of mining.
    (3) The regulatory authority may not approve the permit application 
until the necessary hydrologic, geologic, and biological information 
for the cumulative impact area is available, either from other agencies 
or from you, the applicant.
    (h) Exception for operations that avoid streams. Upon your request, 
the regulatory authority may waive the biological condition information 
requirements of paragraph (e) of this section if you demonstrate, and 
if the regulatory authority finds in writing, that your operation will 
not--
    (1) Mine through or bury a perennial or intermittent stream;
    (2) Create a point-source discharge to any perennial, intermittent, 
or ephemeral stream; or
    (3) Modify the base flow of any perennial or intermittent stream.
    (i) Coordination with Clean Water Act agencies. The regulatory 
authority will consult in a timely manner with the agencies responsible 
for issuing permits, authorizations, and certifications under the Clean 
Water Act and make best efforts to minimize differences in baseline 
data collection points and parameters and to share data to the extent 
practicable and consistent with each agency's mission, statutory 
requirements, and implementing regulations.
    (j) Corroboration of baseline data. The regulatory authority must 
either corroborate a sample of the baseline information in your 
application or arrange for a third party to conduct the corroboration 
at your expense. Corroboration may include, but is not limited to, 
simultaneous sample collection and analysis, use of field measurements, 
or comparison of application data with application or monitoring data 
from adjacent operations.
    (k) Permit nullification for inaccurate information. If the 
regulatory authority issues a permit on the basis of what it later 
determines to be substantially inaccurate baseline information, the 
permit will be void from the date of issuance and have no legal effect. 
You must cease mining-related activities and immediately begin to 
reclaim the disturbed area upon notification by the regulatory 
authority that the permit is void under this paragraph.


Sec.  780.20  How must I prepare the determination of the probable 
hydrologic consequences of my proposed operation (PHC determination)?

    (a) Content of PHC determination. Your permit application must 
contain a determination of the probable hydrologic consequences of the 
proposed operation upon the quality and quantity of surface water and 
groundwater and upon the biological condition of perennial, 
intermittent, and ephemeral streams under seasonal flow conditions for 
the proposed permit and adjacent areas. You must base the PHC 
determination on an analysis of the baseline hydrologic, geologic, 
biological, and other information required under Sec.  780.19 of this 
part. It must include findings on:

diminution, or interruption of an underground or surface source of 
water within the proposed permit or adjacent areas that is used for a 
domestic, agricultural, industrial, or other legitimate purpose.
    (4) Whether the proposed operation will intercept aquifers in 
overburden strata or aquifers in underground mine voids (mine pools) or 
create aquifers in spoil placed in the backfilled area and, if so, what

and after reclamation, and the effect of those impacts on the 
hydrologic balance.
    (5) What impact the proposed operation will have on:

ephemeral streams within the proposed permit and adjacent areas.
    (viii) Other characteristics as required by the regulatory 
authority.
    (b) Supplemental information. (1) The regulatory authority must 
require that you, the applicant, submit supplemental information if the 
PHC determination required by paragraph (a) of this section indicates 
that one of the following conditions exists:
    (i) The proposed operation may result in adverse impacts to the 
hydrologic balance either within or outside the proposed permit area.
    (ii) The proposed operation may result in adverse impacts to the 
biological condition of a perennial or intermittent stream within the 
proposed permit or adjacent areas.
    (iii) Acid-forming or toxic-forming material is present that may 
result in the contamination of either groundwater or surface water used 
as a water supply.
    (2) The supplemental information required under paragraph (b)(1) of 
this section must be adequate to fully evaluate the probable hydrologic 
consequences of the proposed operation and to plan remedial and 
reclamation activities. It may include, but is not limited to, 
additional drilling, geochemical analyses of overburden materials, 
aquifer tests, hydrogeologic analyses of the water-bearing strata, 
analyses of flood flows, or analyses of other characteristics of water 
quality or quantity, including the stability of underground mine pools

authority must review each application for a permit revision to 
determine whether a new or updated PHC determination is needed.
    (2) The regulatory authority must require that you prepare a new or 
updated PHC determination if the review under paragraph (c)(1) of this 
section finds that one is needed.

[[Page 44604]]

Sec.  780.21  What requirements apply to preparation and review of the 
cumulative hydrologic impact assessment (CHIA)?

    (a) General requirements. (1) The regulatory authority must prepare 
a written assessment of the probable cumulative hydrologic impacts of 
the proposed operation and all anticipated mining upon surface-water 
and groundwater systems in the cumulative impact area. This assessment, 
which is known as the CHIA, must be sufficient to determine, for 
purposes of permit approval, whether the proposed operation has been 
designed to prevent material damage to the hydrologic balance outside 
the permit area.
    (2) In preparing the CHIA, the regulatory authority will consider 
relevant information on file for other mining operations located within 
the cumulative impact area or in similar watersheds.
    (3) As provided in Sec.  780.19(g) of this part, the regulatory 
authority may not approve your permit application until it receives the 
hydrologic, geologic, and biological information needed to prepare the 
CHIA, either from other federal and state agencies or from you.
    (b) Contents. At a minimum, the CHIA must include--
    (1) A map of the cumulative impact area. At a minimum, the map must 
identify and display--
    (i) Any difference in the boundaries of the cumulative impact area 
for groundwater and surface water.
    (ii) The locations of all previous, current, and anticipated 
surface and underground mining.
    (iii) The locations of all baseline data collection sites within 
the proposed permit and adjacent areas under Sec.  780.19 of this part.
    (iv) Designated uses of surface water under section 101(a) or 
303(c) of the Clean Water Act.
    (2) A description of all previous, existing, and anticipated 
surface and underground coal mining within the cumulative impact area, 
including, at a minimum, the coal seam or seams mined, the extent of 
mining, and the reclamation status of each operation.
    (3) A description of baseline hydrologic information for the 
proposed permit and adjacent areas under Sec.  780.19 of this part, 
including--
    (i) The quality and quantity of surface water and groundwater and 
seasonal variations therein.
    (ii) Quantitative information about existing usage of surface water 
and groundwater, as well as information defining the quality of water 
required for each existing and reasonably foreseeable use of 
groundwater and surface water and each designated use of surface water 
under section 101(a) or 303(c) of the Clean Water Act.
    (iii) A description and map of the local and regional groundwater 
systems.
    (iv) The biological condition of perennial, intermittent, and 
ephemeral streams.
    (4) A discussion of any potential concerns identified in the PHC 
determination required under Sec.  780.20 of this part and how those 
concerns have been or will be resolved.
    (5) A qualitative and quantitative assessment of how all 
anticipated surface and underground mining may impact the quality of 
surface water and groundwater in the cumulative impact area, expressed 
in terms of each baseline parameter identified under Sec.  780.19 of 
this part.
    (6) Criteria defining material damage to the hydrologic balance 
outside the permit area on a site-specific basis. These criteria must--
    (i) Be expressed in numerical terms for each parameter of concern.
    (ii) Take into consideration the biological requirements of any 
species listed as threatened or endangered under the Endangered Species 
Act when those species or designated critical habitat are present 
within the cumulative impact area.
    (iii) Identify the portion of the cumulative impact area to which 
the criteria apply and locations at which impacts will be monitored. 
The regulatory authority may establish different criteria for subareas 
within the cumulative impact area when appropriate.
    (iv) Be incorporated into the permit.
    (7) An assessment of how all anticipated surface and underground 
mining may affect groundwater movement and availability within the 
cumulative impact area.
    (8) An evaluation, with references to supporting data and analyses, 
of whether the CHIA will support a finding that the operation has been 
designed to prevent material damage to the hydrologic balance outside 
the permit area. To support this finding, the CHIA must include the 
following determinations, with appropriate documentation:
    (i) During all phases of mining and reclamation and at all times of 
the year, variations in streamflow and groundwater availability 
resulting from the operation, as well as variations in the amount and 
concentration of parameters of concern in discharges from the operation 
to groundwater and surface water, will not--
    (A) Result in conversion of a perennial or intermittent stream to 
an ephemeral stream or conversion of a perennial stream to an 
intermittent stream. Conversion of an intermittent stream to a 
perennial stream or conversion of an ephemeral stream to an 
intermittent or perennial stream may be acceptable, provided the 
conversion would not disrupt or preclude any existing, reasonably 
foreseeable, or designated use of the stream under section 101(a) or 
303(c) of the Clean Water Act and would not adversely impact threatened 
or endangered species or designated critical habitat in violation of 
the Endangered Species Act.
    (B) Result in an exceedance of applicable water quality standards 
in any stream located outside the permit area.
    (C) Disrupt or preclude any existing or reasonably foreseeable use 
of surface water outside the permit area or any designated use of 
surface water under section 101(a) or 303(c) of the Clean Water Act 
outside the permit area, except as provided in Sec. Sec.  780.22(b) and 
816.40 of this chapter.
    (D) Disrupt or preclude any existing or reasonably foreseeable use 
of groundwater outside the permit area, except as provided in 
Sec. Sec.  780.22(b) and 816.40 of this chapter.
    (ii) The operation has been designed to ensure that neither the 
mining operation nor the final configuration of the reclaimed area will 
result in changes in the size or frequency of peak flows from 
precipitation events or thaws that would cause an increase in damage 
from flooding, when compared with premining conditions.
    (iii) Perennial and intermittent streams located outside the permit 
area but within the cumulative impact area will continue to have 
sufficient base flow and recharge capacity to maintain their premining 
flow regime; i.e., perennial stream segments will retain perennial 
flows and intermittent stream segments will retain intermittent flows 
both during and after mining and reclamation. Conversion of an 
intermittent stream to a perennial stream or conversion of an ephemeral 
stream to an intermittent or perennial stream may be acceptable, 
provided the conversion would not disrupt or preclude any existing, 
reasonably foreseeable, or designated use of the stream under section 
101(a) or 303(c) of the Clean Water Act and would not adversely impact 
threatened or endangered species or designated critical habitat in 
violation of the Endangered Species Act.
    (iv) The operation has been designed to protect the quantity and 
quality of water in any aquifer that significantly ensures the 
prevailing hydrologic balance.

[[Page 44605]]

    (c) Subsequent reviews. (1) The regulatory authority must review 
each application for a significant permit revision to determine whether 
a new or updated CHIA is needed. The regulatory authority must document 
the review, including the analysis and conclusions, together with the 
rationale for the conclusions, in writing.
    (2)(i) The regulatory authority must reevaluate the CHIA during the 
permit renewal process to determine whether the CHIA remains accurate 
and whether the material damage criteria in the CHIA and the permit are 
adequate to ensure that material damage to the hydrologic balance 
outside the permit area will not occur. This evaluation must include a 
review of all water monitoring data from both this operation and all 
other coal mining operations within the cumulative impact area.
    (ii) If the permit has a term longer than 5 years, the regulatory 
authority must conduct the review required by paragraph (c)(2)(i) of 
this section at intervals not to exceed 5 years.
    (3) The regulatory authority must prepare a new or updated CHIA if 
the review conducted under paragraph (c)(1) or (2) of this section 
finds that one is needed.


Sec.  780.22  What information must I include in the hydrologic 
reclamation plan and what information must I provide on alternative 
water sources?

    (a) Hydrologic reclamation plan. Your permit application must 
include a plan, with maps and descriptions, that demonstrates how the 
proposed operation will comply with the applicable provisions of 
subchapter K of this chapter that relate to protection of the 
hydrologic balance. The plan must--
    (1) Be specific to local hydrologic conditions.
    (2) Include preventive or remedial measures for any potential 
adverse hydrologic consequences identified in the PHC determination 
prepared under Sec.  780.20 of this part. These measures must describe 
the steps that you will take during mining and reclamation through 
final bond release under Sec.  800.42(d) of this chapter to--
    (i) Minimize disturbances to the hydrologic balance within the 
proposed permit and adjacent areas.
    (ii) Prevent material damage to the hydrologic balance outside the 
proposed permit area.
    (iii) Meet applicable water quality laws and regulations.
    (iv) Protect the rights of existing water users in accordance with 
paragraph (b) of this section and Sec.  816.40 of this chapter.
    (v) Avoid acid or toxic discharges to surface water and avoid or, 
if avoidance is not possible, minimize degradation of groundwater.
    (vi) Prevent, to the extent possible using the best technology 
currently available, additional contributions of suspended solids to 
streamflow or to runoff outside the proposed permit area.
    (vii) Provide water-treatment facilities when needed.
    (viii) Control surface-water runoff in accordance with Sec.  780.29 
of this part.
    (ix) Restore the approximate premining recharge capacity.
    (3) Address the impacts of any transfers of water among active and 
abandoned mines within the proposed permit and adjacent areas.
    (4) Describe the steps that you will take during mining and 
reclamation through final bond release under Sec.  800.42(d) of this 
chapter to protect and enhance aquatic life and related environmental 
values to the extent possible using the best technology currently 
available.
    (b) Alternative water source information. (1) If the PHC 
determination prepared under Sec.  780.20 of this part indicates that 
the proposed mining operation may result in contamination, diminution, 
or interruption of an underground or surface source of water within the 
proposed permit or adjacent areas that is used for a domestic, 
agricultural, industrial, or other legitimate purpose, your application 
must demonstrate that alternative water sources are both available and 
feasible to develop. The alternative water sources must be of suitable 
quality and sufficient in quantity to support existing premining uses 
and approved postmining land uses.
    (2) If you cannot identify an alternative water source that is both 
suitable and available, you must modify your application to prevent the 
proposed operation from contaminating, interrupting, or diminishing any 
water supply protected under Sec.  816.40 of this chapter.
    (3)(i) When a suitable alternative water source is available, your 
operation plan must require that the alternative water supply be 
developed and installed on a permanent basis before your operation may 
adversely affect an existing water supply protected under Sec.  816.40 
of this chapter.
    (ii) Paragraph (b)(3)(i) of this section will not apply immediately 
if you demonstrate, and the regulatory authority finds, that the 
proposed operation also would adversely affect the replacement supply. 
In that case, your plan must require provision of a temporary 
replacement water supply until it is safe to install the permanent 
replacement water supply required under paragraph (b)(3)(i) of this 
section.
    (4) Your application must describe how you will provide both 
temporary and permanent replacements for any unexpected losses of water 
supplies protected under Sec.  816.40 of this chapter.

area. The plan must--
    (i) Identify the parameters to be monitored.
    (ii) Specify the sampling frequency for each parameter.
    (iii) Establish a sufficient number of appropriate monitoring 
locations to evaluate the accuracy of the findings in the PHC 
determination, to identify adverse trends, and to determine, in a 
timely fashion, whether corrective action is needed to prevent material 
damage to the hydrologic balance outside the permit area. At a minimum, 
the plan must include--
    (A) For each aquifer above or immediately below the lowest coal 
seam to be mined, monitoring wells or equivalent monitoring points 
located upgradient and downgradient of the proposed operation.
    (B) Monitoring wells placed in backfilled portions of the permit 
area after backfilling and grading of all or a portion of the permit

groundwater quality.
    (C) Monitoring wells in any existing underground mine workings that 
would have a direct hydrological connection to the proposed operation.
    (iv) Describe how the monitoring data will be used to--

initiate, implement, approve, or authorize the proposed use of the land 
following reclamation.
    (5) You must explain how the proposed postmining land use will be 
achieved and identify any support activities or facilities needed to 
achieve that use.
    (6) If you propose to restore the proposed permit area or a portion 
thereof to a condition capable of supporting a higher or better use or 
uses rather than to a condition capable of supporting the uses that the 
land could support before any mining, you must--
    (i) Provide the demonstration required under paragraph (b)(1) of 
this section.
    (ii) Disclose any monetary compensation, item of value, or other 
consideration that you or your agent provided or expect to provide to

support before any mining, you must demonstrate that the proposed 
higher or better use or uses meet the following criteria:
    (i) There is a reasonable likelihood that the proposed use or uses 
will be achieved after mining and reclamation, as documented by, for 
example, real estate and construction contracts, plans for installation 
of any necessary infrastructure, procurement of any necessary zoning 
approvals, landowner commitments, economic forecasts, and studies by 
land use planning agencies.
    (ii) The proposed use or uses do not present any actual or probable 
hazard to public health or safety or any threat of water diminution or

the reclaimed area that would cause an increase in damage from flooding 
when compared with the conditions that would exist if the land were 
restored to a condition capable of supporting the uses that it was 
capable of supporting before any mining.
    (F) Cause the total volume of flow from the reclaimed area, during 
every season of the year, to vary in a way that would preclude any 
existing or reasonably foreseeable use of surface water or groundwater 
or any designated use of surface water under section 101(a) or 303(c) 
of the Clean Water Act.
    (G) Cause a change in the temperature or chemical composition of 
the water that would preclude any existing or reasonably foreseeable 
use of surface water or any designated use of surface water under 
section 101(a) or 303(c) of the Clean Water Act.
    (2) Regulatory authority decision requirements. The regulatory 
authority may approve your request if it--
    (i) Consults with the landowner or the land management agency 
having jurisdiction over the lands to which the use would apply; and
    (ii) Finds in writing that you have made the demonstration required 
under paragraph (b)(1) of this section.

the structures are consistent with and proportional to the needs of the 
postmining land use.
    (2) The amount of bond required for the permit under part 800 of 
this chapter must include the cost of removing the structure and 
reclaiming the land upon which it was located to a condition capable of 
supporting the premining uses. The bond must include the cost of 
restoring the site to its approximate original contour in accordance 
with Sec.  816.102 of this chapter and establishing native vegetation 
in accordance with Sec.  816.111 of this chapter.
    (3) The reclamation plan submitted under Sec.  780.12 of this part 
must specify that if a structure is not in use as part of the approved 
postmining land use by the end of the revegetation responsibility 
period specified in Sec.  816.115 of this chapter, you must remove the 
structure and reclaim the land upon which it was located by restoring 
the approximate original contour in accordance with Sec.  816.102 of 
this chapter and establishing native vegetation in accordance with 
Sec.  816.111 of this chapter.
    (e) What special provisions apply to previously mined areas? If 
land that was previously mined cannot be reclaimed to the land use that 
existed before any mining because of the previously mined condition, 
you may propose, and the regulatory authority may approve, any 
appropriate postmining land use for that land that is both achievable 
and compatible with land uses in the surrounding area, provided that 
you comply with paragraphs (a) and (b)(1)(iv) of this section.

intermittent, and ephemeral streams. (i) If you propose to conduct an 
activity identified in paragraph (b)(1) of this section, you must 
propose to establish a riparian corridor at least 100 feet wide on each 
side of the stream as part of the reclamation process following the 
completion of mining activities within that corridor. The corridor 
width must be measured horizontally on a line perpendicular to the 
stream beginning at the bankfull elevation or, if there are no 
discernible banks, the centerline of the active channel.
    (ii) You must use native species, including species adapted to and 
suitable for planting in riparian zones within that corridor, to 
revegetate disturbed areas within the corridor required under paragraph 
(b)(3)(i) of this section. For areas that are forested at the time of 
application or that would revert to forest under conditions of natural 
succession, you must use native trees and shrubs to meet this 
requirement.
    (iii) Paragraph (b)(3)(i) of this section does not apply to--
    (A) Prime farmland historically used for cropland;
    (B) Situations in which revegetation would be incompatible with an 
approved postmining land use that is implemented during the 
revegetation responsibility period before final bond release under 
Sec.  800.42(d) of this chapter; or
    (C) Streams buried beneath an excess spoil fill or a coal mine 
waste disposal facility under paragraph (d) of this section.
    (c) What additional requirements apply to an application that 
proposes to mine through or divert a perennial, intermittent, or 
ephemeral stream?--(1) Postmining drainage pattern. The postmining 
drainage pattern of perennial, intermittent, and ephemeral stream 
channels that you propose to restore after the completion of mining 
must be similar to the premining drainage pattern, unless the 
regulatory authority approves a different pattern to--
    (i) Ensure stability;
    (ii) Prevent or minimize downcutting of reconstructed stream 
channels; or
    (iii) Promote enhancement of fish and wildlife habitat.
    (2) Mining through or diverting a perennial or intermittent stream. 
If you propose to mine through or divert a perennial or intermittent 
stream, you must--
    (i) Comply with the requirements of paragraphs (a) through (c)(1) 
of this section.
    (ii) Demonstrate that there is no reasonable alternative that would 
avoid mining through or diverting the stream.
    (iii) Design the operation to minimize the extent to which the 
stream will be mined through or diverted.
    (iv) Demonstrate that you can restore the form and ecological 
function of the affected stream segment, as required by Sec.  816.57(b) 
of this chapter, using the techniques in the proposed reclamation plan.
    (A) Those techniques must include the selective placement of low-
permeability materials in the backfill or fill and associated stream 
channels to create the aquitards necessary to support streamflow when 
the goal is to reestablish a perennial or intermittent stream, unless 
you can demonstrate an alternative method of restoring perennial or 
intermittent streamflow.
    (B) You must include a separate bond calculation for the cost of 
restoring the ecological function of the affected stream segment. You 
must post a surety bond, a collateral bond, or a combination of surety 
and collateral bonds to cover that cost before the regulatory authority 
may issue the permit.
    (v) Comply with the following stream-channel restoration and 
stream-channel diversion design requirements:
    (A) Designs for permanent stream-channel diversions, temporary 
stream-

[[Page 44611]]

channel diversions that will remain in use for 2 or more years, and 
stream channels to be restored after the completion of mining must 
adhere to design techniques that will restore or approximate the 
premining characteristics of the original stream channel to promote the 
recovery and enhancement of the aquatic habitat and to minimize adverse 
alteration of stream channels on and off the site, including channel 
deepening or enlargement. The premining characteristics of the original 
stream channel include, but are not limited to, the baseline stream 
pattern, profile, dimensions, substrate, habitat, and natural 
vegetation growing in the riparian zone. For temporary stream-channel 
diversions that will remain in use for 2 or more years, the vegetation 
proposed for planting in the riparian zone need not include species 
that would not reach maturity until after the diversion is removed.
    (B) The designed hydraulic capacity of all temporary and permanent 
stream-channel diversions must be at least equal to the hydraulic 
capacity of the unmodified stream channel immediately upstream of the 
diversion, but no greater than the hydraulic capacity of the unmodified 
stream channel immediately downstream from the diversion.
    (C) All temporary and permanent stream-channel diversions must be 
designed so that the combination of channel, bank, and flood-plain 
configuration is adequate to pass safely the peak runoff of a 10-year, 
6-hour precipitation event for a temporary diversion and a 100-year, 6-
hour precipitation event for a permanent diversion.
    (vi) Submit a certification from a qualified registered 
professional engineer that the designs for all stream-channel 
diversions and all stream channels to be restored after the completion 
of mining meet the design requirements of this section and any 
additional design criteria established by the regulatory authority. 
This certification may be limited to the location, dimensions, and 
physical characteristics of the stream channel; it need not include 
restoration of ecological function.
    (d) What requirements apply to an application to construct an 
excess spoil fill or a coal mine waste disposal facility in a perennial 
or intermittent stream?--(1) Applicability. If you propose to construct 
an excess spoil fill under Sec.  780.35 of this part or a coal mine 
waste disposal facility under Sec.  780.25(d) of this part, you must 
comply with the requirements of paragraph (d)(2) of this section in 
place of the requirements of paragraph (b)(2) of this section whenever 
the fill or disposal facility would encroach upon any part of a 
perennial or intermittent stream.
    (2) Application requirements. If you propose to construct an excess 
spoil fill or coal mine waste disposal facility of the nature described 
in paragraph (d)(1) of this section, your application must demonstrate 
that--
    (i) The operation has been designed to minimize the amount of 
excess spoil or coal mine waste generated.
    (ii) After evaluating all potential upland locations in the 
vicinity of the proposed operation, there is no practicable alternative 
that would avoid placement of excess spoil or coal mine waste in a 
perennial or intermittent stream.
    (iii) To the extent possible using the best technology currently 
available, the proposed excess spoil fill or coal mine waste disposal 
facility has been designed to minimize--
    (A) Placement of excess spoil or coal mine waste in a perennial or 
intermittent stream.
    (B) Adverse impacts on fish, wildlife, and related environmental 
values.
    (iv) The fish and wildlife enhancement plan submitted under Sec.  
780.16 of this part includes measures that would fully and permanently 
offset any long-term adverse impacts that the fill, refuse pile, or 
coal mine waste impoundment would have on fish, wildlife, and related 
environmental values within the footprint of the fill, refuse pile, or 
impoundment.
    (v) The excess spoil fill or coal mine waste disposal facility has 
been designed in a manner that will not cause or contribute to a 
violation of water quality standards or result in the formation of 
toxic mine drainage.
    (vi) The revegetation plan submitted under Sec.  780.12(g) of this 
part requires reforestation of the completed excess spoil fill if the 
land is forested at the time of application or if it would revert to 
forest under conditions of natural succession.
    (e) What are the regulatory authority's responsibilities?--(1) 
Standards for restoration of the ecological function of a stream. (i) 
The regulatory authority must establish objective standards for 
determining when the ecological function of a restored or permanently-
diverted perennial or intermittent stream has been restored.

    (2) The quantity of the existing topsoil and subsoil on the 
proposed permit area is insufficient to provide the optimal rooting 
depth or to meet other growth requirements of the native species to be 
planted. In this case, the plan must require that all available 
existing topsoil and favorable subsoil, regardless of the amount, be 
removed, stored, and redistributed as part of the final growing medium.
    (B) The use of the overburden materials that you have selected, in 
combination with or in place of the topsoil or subsoil, will result in 
a soil medium that is more suitable than the existing topsoil and 
subsoil to sustain vegetation consistent with the postmining land use 
and the revegetation plan under paragraph (g) of this section and that 
will provide a rooting depth that is superior to the existing topsoil 
and subsoil.
    (C) The overburden materials that you select for use as a soil 
substitute or supplement are the best materials available in the 
proposed permit area to support the native vegetation to be established 
or the crops to be planted.

plans developed in accordance with that law.
    (c) Protection of other species. You must describe how, to the 
extent possible using the best technology currently available, you will 
minimize disturbances and adverse impacts on fish, wildlife, and 
related environmental values. At a minimum, you must explain how you 
will--
    (1) Time operations to avoid or minimize disruption of critical 
life cycle events for fish and wildlife, including migration, nesting, 
breeding, calving, and spawning.
    (2) Retain forest cover and other native vegetation as long as

impacts on aquatic and terrestrial species.
    (3) To the extent possible, maintain an intact forested buffer at 
least 100 feet wide between surface disturbances and perennial and 
intermittent streams that are located in forested areas. The buffer 
width must be measured horizontally on a line perpendicular to the 
stream beginning at the bankfull elevation or, if there are no 
discernible banks, the centerline of the active channel.

the banks of streams that lacked a buffer of this nature before mining. 
The corridor width should be measured horizontally on a line 
perpendicular to the stream beginning at the bankfull elevation or, if 
there are no discernible banks, the centerline of the active channel. 
Species selected for planting within the corridor must be native to the

of this section that you will implement if your mining activities would 
result in the long-term loss of native forest, other native plant 
communities, or a segment of a perennial or intermittent stream.
    (ii) The scope of the enhancement measures that you propose under 
paragraph (d)(2)(i) of this section must be commensurate with the 
magnitude of the long-term adverse impacts of the proposed operation. 
Whenever possible, the measures must be permanent.

[[Page 44621]]

    (iii)(A) Enhancement measures proposed under paragraph (d)(2) of 
this section must be implemented within the watershed in which the 
proposed operation is located, unless opportunities for enhancement are 
not available within that watershed. In that case, you must propose to 
implement enhancement measures in the closest adjacent watershed in 
which enhancement opportunities exist, as approved by the regulatory

this chapter does not include threatened or endangered species, 
designated critical habitat, or species proposed for listing as 
threatened or endangered, the regulatory authority must provide the 
protection and enhancement plan to the applicable regional or field 
office of the U.S. Fish and Wildlife Service only if the Service 
requests an opportunity to review and comment on that plan. The 
regulatory authority must provide the requested plan to the Service 
within 10 days of receipt of the request from the Service.
    (2)(i) The regulatory authority must document its disposition of 
all comments from the Service that pertain to fish and wildlife or 
plants listed as threatened or endangered under the Endangered Species 
Act of 1973, 16 U.S.C. 1531 et seq., or to critical habitat designated 
under that law.
    (ii) If the regulatory authority does not agree with a species-
specific protection measure or any other recommendation from the 
Service that pertains to fish and wildlife or plants listed as 
threatened or endangered under the Endangered Species Act of 1973, 16 
U.S.C. 1531 et seq., or to critical habitat designated under that law, 
the regulatory authority must explain the rationale for that decision 
in the disposition document prepared under paragraph (e)(2)(i) of this 
section. The regulatory authority must provide a copy of that document 
to the pertinent Service field office and OSMRE field office and must 
refrain from approving the permit application.
    (iii) If the Service field office does not concur with the 
regulatory authority's decision under paragraph (e)(2)(ii) of this 
section and the regulatory authority and the Service field office are 
unable to reach agreement at that level, either the regulatory 
authority or the Service may elevate the issue through the chain of 
command of the regulatory authority, the Service, and OSMRE for 
resolution.
    (iv) The regulatory authority may not approve the permit 
application until all issues are resolved in accordance with paragraph 
(e)(2)(iii) of this section and the regulatory authority receives 
written documentation from the Service that all issues have been 
resolved.

description must include--
    (i) The areal and structural geology of the proposed permit and 
adjacent areas.
    (ii) Other parameters that influence the required reclamation.
    (iii) An explanation of how the areal and structural geology may

potentially impacted surface water and groundwater.
    (iv) The composition of the base of each perennial and intermittent 
stream within the proposed permit and adjacent areas, together with a 
prediction of how that base would respond to subsidence of strata 
overlying the proposed underground mine workings and how subsidence 
would impact streamflow.
    (2) The description required by paragraph (f)(1) of this section 
must be based on all of the following--
    (i) The cross-sections, maps, and plans required by Sec.  783.24 of 
this chapter.
    (ii) The information obtained under paragraphs (f)(3) through 
(f)(5) of this section.
    (iii) Geologic literature and practices.
    (3) For any portion of the proposed permit area in which the strata 
down to the coal seam to be mined will be removed or are already 
exposed, you must collect and analyze samples from test borings; drill 
cores; or fresh, unweathered, uncontaminated samples from rock 
outcrops, down to and including the deeper of either the stratum 
immediately below the lowest coal seam to be mined or any aquifer below 
the lowest seam to be mined that may be adversely impacted by mining. 
Your application must include the following data and analyses:
    (i) Logs showing the lithologic characteristics, including physical 
properties and thickness, of each stratum, and the location of any 
groundwater encountered.
    (ii) Chemical analyses identifying those strata that may contain 
acid-forming materials, toxic-forming materials, or alkalinity-
producing materials and the extent to which each stratum contains those 
materials.
    (iii) Chemical analyses of the coal seam for acid-forming or toxic-
forming materials, including, but not limited to, total sulfur and 
pyritic sulfur.
    (4) For lands within the permit and adjacent areas where the strata

and analyze samples from test borings or drill cores. Your application 
must include the following data and analyses:
    (i) Logs showing the lithologic characteristics, including physical 
properties and thickness, of each stratum that may be impacted, and the 
location of any groundwater encountered.

any, in the strata immediately above and below each coal seam to be 
mined.
    (5) You must provide any additional geologic information and 
analyses that the regulatory authority determines to be necessary to 
protect the hydrologic balance, to minimize or prevent subsidence, or 
to meet the performance standards of this chapter.
    (6) You may request the regulatory authority to waive the 
requirements of paragraphs (f)(3) and (4) of this section, in whole or 
in part. The regulatory authority may grant the waiver request only 
after finding in writing that the collection and analysis of that data 
is unnecessary because other representative information is available to 
the regulatory authority in a satisfactory form.
    (g) Cumulative impact area information. (1) The regulatory 
authority will obtain the hydrologic, geologic, and biological 
information necessary to assess the probable cumulative hydrologic 
impacts of the proposed operation and all anticipated mining on 
surface-water and groundwater systems in the cumulative impact area, as 
required by Sec.  784.21 of this part, from the appropriate federal or 
state agencies, to the extent that the information is available from 
those agencies.
    (2) If the information identified in paragraph (g)(1) of this 
section is not available from other federal or state agencies, you must 
gather and submit this information to the regulatory authority as part 
of the permit application before the regulatory authority may approve 
your application. As an alternative to collecting new information, you 
may submit data and analyses from nearby mining operations if the site 
of those operations is representative of the proposed operations in 
terms of topography, hydrology, geology, geochemistry, and method of 
mining.
    (3) The regulatory authority may not approve the permit application 
until the necessary hydrologic, geologic, and biological information 
for the cumulative impact area is available, either from other agencies 
or from you, the applicant.
    (h) Exception for operations that avoid streams. Upon your request, 
the regulatory authority may waive the biological condition information 
requirements of paragraph (e) of this section if you demonstrate, and 
if the regulatory authority finds in writing, that your operation will 
not--
    (1) Mine through or bury a perennial or intermittent stream;
    (2) Create a point-source discharge to any perennial, intermittent, 
or ephemeral stream; or
    (3) Modify the base flow of any perennial or intermittent stream or 
cause the stream to pool, either as a result of subsidence or as a 
result of any other mining-related activity.
    (i) Coordination with Clean Water Act agencies. The regulatory 
authority will consult in a timely manner with the agencies responsible 
for issuing permits, authorizations, and certifications under the Clean 
Water Act and make best efforts to minimize differences in baseline 
data collection points and parameters and to share data to the extent 
practicable and consistent with each agency's mission, statutory 
requirements, and implementing regulations.
    (j) Corroboration of baseline data. The regulatory authority must 
either corroborate a sample of the baseline information in your 
application or arrange for a third party to conduct the corroboration 
at your expense. Corroboration may include, but is not limited to, 
simultaneous sample collection and analysis, use of field measurements, 
or comparison of application data with application or monitoring data 
from adjacent operations.
    (k) Permit nullification for inaccurate information. If the 
regulatory authority issues a permit on the basis of what it later 
determines to be substantially inaccurate baseline information, the 
permit will be void from the date of issuance and have no legal effect. 
You must cease mining-related activities and immediately begin to 
reclaim the disturbed area upon notification by the regulatory 
authority that the permit is void under this paragraph.


Sec.  784.20  How must I prepare the determination of the probable 
hydrologic consequences of my proposed operation (PHC determination)?

    (a) Content of PHC determination. Your permit application must 
contain a determination of the probable hydrologic consequences of the 
proposed operation upon the quality and quantity of surface water and 
groundwater and upon the biological condition of perennial, 
intermittent, and ephemeral streams under seasonal flow conditions for 
the proposed permit and adjacent areas. You must base the PHC 
determination on an analysis of the baseline hydrologic, geologic, 
biological, and other information required under Sec.  784.19 of this 
part. It must include findings on:
    (1) Whether the operation may cause material damage to the 
hydrologic balance outside the permit area.

    (i) The highest potentiometric surface of the mine pool after 
closure.
    (ii) Whether, where, and when the mine pool is likely to result in 
a surface discharge, either via gravity or as a result of hydrostatic

disturbances.
    (vi) The potential for the mine pool to destabilize surface 
features.
    (vii) The potential impact of roof collapses on mine pool behavior

PHC determination required by paragraph (a) of this section indicates 
that one of the following conditions exists:
    (i) The proposed operation may result in adverse impacts to the 
hydrologic balance either within or outside the proposed permit area.
    (ii) The proposed operation may result in adverse impacts to the 
biological condition of a perennial or intermittent stream within the 
proposed permit or adjacent areas.
    (iii) Acid-forming or toxic-forming material is present that may 
result in the contamination of either groundwater or surface water used 
as a water supply.
    (2) The supplemental information required under paragraph (b)(1) of 
this section must be adequate to fully evaluate the probable hydrologic 
consequences of the proposed operation and to plan remedial and 
reclamation activities. It may include, but is not limited to, 
additional drilling, geochemical analyses of overburden materials, 
aquifer tests, hydrogeologic analyses of the water-bearing strata, 
analyses of flood flows, or analyses of other characteristics of water 
quality or quantity, including the stability of underground mine pools 
that might be affected by the proposed operation and the stability of 
any mine pool created by the proposed operation.
    (c) Subsequent reviews of PHC determinations. (1) The regulatory 
authority must review each application for a permit revision to 
determine whether a new or updated PHC determination is needed.
    (2) The regulatory authority must require that you prepare a new or 
updated PHC determination if the review under paragraph (c)(1) of this 
section finds that one is needed.


Sec.  784.21  What requirements apply to preparation and review of the 
cumulative hydrologic impact assessment (CHIA)?

    (a) General requirements. (1) The regulatory authority must prepare 
a written assessment of the probable cumulative hydrologic impacts of 
the proposed operation and all anticipated mining upon surface-water 
and groundwater systems in the cumulative impact area. This assessment, 
which is known as the CHIA, must be sufficient to determine, for 
purposes of permit approval, whether the proposed operation has been 
designed to prevent material damage to the hydrologic balance outside 
the permit area.
    (2) In preparing the CHIA, the regulatory authority will consider 
relevant information on file for other mining operations located within 
the cumulative impact area or in similar watersheds.
    (3) As provided in Sec.  784.19(g) of this part, the regulatory 
authority may not approve your permit application until it receives the 
hydrologic, geologic, and biological information needed to prepare the 
CHIA, either from other federal and state agencies or from you.
    (b) Contents. At a minimum, the CHIA must include--
    (1) A map of the cumulative impact area. At a minimum, the map must 
identify and display--
    (i) Any difference in the boundaries of the cumulative impact area 
for groundwater and surface water.
    (ii) The locations of all previous, current, and anticipated 
surface and underground mining.
    (iii) The locations of all baseline data collection sites within 
the proposed permit and adjacent areas under Sec.  784.19 of this part.
    (iv) Designated uses of surface water under section 101(a) or 
303(c) of the Clean Water Act.
    (2) A description of all previous, existing, and anticipated 
surface and underground coal mining within the cumulative impact area, 
including, at a minimum, the coal seam or seams mined, the extent of 
mining, and the reclamation status of each operation.
    (3) A description of baseline hydrologic information for the 
proposed permit and adjacent areas under Sec.  784.19 of this part, 
including--
    (i) The quality and quantity of surface water and groundwater and 
seasonal variations therein.
    (ii) Quantitative information about existing usage of surface water 
and groundwater, as well as information defining the quality of water 
required for each existing and reasonably foreseeable use of 
groundwater and surface water and each designated use of surface water 
under section 101(a) or 303(c) of the Clean Water Act.
    (iii) A description and map of the local and regional groundwater 
systems.
    (iv) The biological condition of perennial, intermittent, and 
ephemeral streams.
    (4) A discussion of any potential concerns identified in the PHC 
determination required under Sec.  784.20 of this part and how those 
concerns have been or will be resolved.
    (5) A quantitative assessment of how all anticipated surface and 
underground mining may impact the quality of surface water and 
groundwater in the cumulative impact area, expressed in terms of each 
baseline parameter identified under Sec.  784.19 of this part.
    (6) Criteria defining material damage to the hydrologic balance 
outside the permit area on a site-specific basis. These criteria must--
    (i) Be expressed in numerical terms for each parameter of concern.
    (ii) Take into consideration the biological requirements of any 
species listed as threatened or endangered under the Endangered Species 
Act when those species or designated critical habitat are present 
within the cumulative impact area.
    (iii) Identify the portion of the cumulative impact area to which 
the criteria apply and the locations at which impacts will be 
monitored. The regulatory authority may establish different criteria 
for subareas within the cumulative impact area when appropriate.
    (iv) Be incorporated into the permit.
    (7) An assessment of how all anticipated surface and underground 
mining may affect groundwater movement and availability within the 
cumulative impact area.
    (8) An evaluation, with references to supporting data and analyses, 
of whether the CHIA will support a finding that the proposed operation 
has been

[[Page 44626]]

designed to prevent material damage to the hydrologic balance outside 
the permit area. To support this finding, the CHIA must include the 
following determinations, with appropriate documentation--
    (i) During all phases of mining and reclamation and at all times of 
the year, variations in streamflow and groundwater availability 
resulting from the operation, as well as variations in the amount and 
concentration of parameters of concern in discharges from the operation 
to groundwater and surface water, will not--
    (A) Result in conversion of a perennial or intermittent stream to 
an ephemeral stream or conversion of a perennial stream to an 
intermittent stream. Conversion of an intermittent stream to a 
perennial stream or conversion of an ephemeral stream to an 
intermittent or perennial stream may be acceptable, provided the 
conversion would not disrupt or preclude any existing, reasonably 
foreseeable, or designated use of the stream under section 101(a) or 
303(c) of the Clean Water Act and would not adversely impact threatened 
or endangered species or designated critical habitat in violation of 
the Endangered Species Act.
    (B) Result in an exceedance of applicable water quality standards 
in any stream located outside the permit area.
    (C) Disrupt or preclude any existing or reasonably foreseeable use 
of surface water outside the permit area or any designated use of 
surface water under section 101(a) or 303(c) of the Clean Water Act 
outside the permit area, except as provided in Sec. Sec.  784.22(b) and 
817.40 of this chapter.
    (D) Disrupt or preclude any existing or reasonably foreseeable use 
of groundwater outside the permit area, except as provided in 
Sec. Sec.  784.22(b) and 817.40 of this chapter.
    (ii) The operation has been designed to ensure that neither the 
mining operation nor the final configuration of the reclaimed area will 
result in changes in the size or frequency of peak flows from 
precipitation events or thaws that would cause an increase in damage 
from flooding, when compared with premining conditions.
    (iii) Perennial and intermittent streams located outside the permit 
area but within the cumulative impact area will continue to have 
sufficient base flow and recharge capacity to maintain their premining 
flow regime; i.e., perennial stream segments will retain perennial 
flows and intermittent stream segments will retain intermittent flows 
both during and after mining and reclamation. Conversion of an 
intermittent stream to a perennial stream or conversion of an ephemeral 
stream to an intermittent or perennial stream may be acceptable, 
provided the conversion does not disrupt or preclude any existing, 
reasonably foreseeable, or designated use of the stream under section 
101(a) or 303(c) of the Clean Water Act and would not adversely impact 
threatened or endangered species or designated critical habitat in 
violation of the Endangered Species Act.
    (iv) The operation has been designed to protect the quantity and 
quality of water in any aquifer that significantly ensures the 
prevailing hydrologic balance.
    (c) Subsequent reviews. (1) The regulatory authority must review 
each application for a significant permit revision to determine whether 
a new or updated CHIA is needed. The regulatory authority must document 
the review, including the analysis and conclusions, together with the 
rationale for the conclusions, in writing.
    (2)(i) The regulatory authority must reevaluate the CHIA during the 
permit renewal process to determine whether the CHIA remains accurate 
and whether the material damage criteria in the CHIA and the permit are 
adequate to ensure that material damage to the hydrologic balance 
outside the permit area will not occur. This evaluation must include a 
review of all water monitoring data from both this operation and all 
other coal mining operations within the cumulative impact area.
    (ii) If the permit has a term longer than 5 years, the regulatory 
authority must conduct the review required by paragraph (c)(2)(i) of 
this section at intervals not to exceed 5 years.
    (3) The regulatory authority must prepare a new or updated CHIA if 
the review conducted under paragraph (c)(1) or (2) of this section 
finds that one is needed.


Sec.  784.22  What information must I include in the hydrologic 
reclamation plan and what information must I provide on alternative 
water sources?

    (a) Hydrologic reclamation plan. Your permit application must 
include a plan, with maps and descriptions, that demonstrates how the 
proposed operation will comply with the applicable provisions of this 
subchapter and subchapter K of this chapter that relate to protection 
of the hydrologic balance. The plan must--
    (1) Be specific to local hydrologic conditions.
    (2) Include preventive or remedial measures for any potential 
adverse hydrologic consequences identified in the PHC determination 
prepared under Sec.  784.20 of this part. These measures must describe 
the steps that you will take during mining and reclamation through 
final bond release under Sec.  800.42(d) of this chapter to--
    (i) Minimize disturbances to the hydrologic balance within the 
proposed permit and adjacent areas.
    (ii) Prevent material damage to the hydrologic balance outside the 
proposed permit area.
    (iii) Meet applicable water quality laws and regulations.
    (iv) Protect existing water users in accordance with paragraph (b) 
of this section and Sec.  817.40 of this chapter.
    (v) Avoid acid or toxic discharges to surface water and avoid or, 
if avoidance is not possible, minimize degradation of groundwater.
    (vi) Prevent, to the extent possible using the best technology 
currently available, additional contributions of suspended solids to 
streamflow or to runoff outside the proposed permit area.
    (vii) Provide water-treatment facilities when needed.
    (viii) Control surface-water runoff in accordance with Sec.  784.29 
of this part.
    (3) Address the impacts of any transfers of water among active and 
abandoned mines within the proposed permit and adjacent areas.
    (4) Describe the steps that you will take during mining and 
reclamation through final bond release under Sec.  800.42(d) of this 
chapter to protect and enhance aquatic life and related environmental 
values to the extent possible using the best technology currently 
available.
    (b) Alternative water source information. (1) If the PHC 
determination prepared under Sec.  784.20 of this part indicates that 
underground mining activities conducted after October 24, 1992, may 
result in contamination, diminution, or interruption of a well or 
spring that is in existence at the time the permit application is 
submitted and that is used for domestic, drinking, or residential 
purposes, your application must demonstrate that alternative water 
sources are both available and feasible to develop. The alternative 
water sources must be of suitable quality and sufficient in quantity to 
support existing premining uses and approved postmining land uses.
    (2) If you cannot identify an alternative water source that is both 
suitable and available, you must modify your application to prevent the 
proposed operation from contaminating, interrupting, or diminishing any 
water supply protected under Sec.  817.40 of this chapter.

[[Page 44627]]

    (3)(i) When a suitable alternative water source is available, your 
operation plan must require that the alternative water supply be 
developed and installed on a permanent basis before your operation may 
adversely affect an existing water supply protected under Sec.  817.40 
of this chapter.
    (ii) Paragraph (b)(3)(i) of this section will not apply immediately 
if you demonstrate, and the regulatory authority finds, that the 
proposed operation also would adversely affect the replacement supply. 
In that case, your plan must require provision of a temporary 
replacement water supply until it is safe to install the permanent 
replacement water supply required under paragraph (b)(3)(i) of this 
section.
    (4) Your application must describe how you will provide both 
temporary and permanent replacements for any unexpected losses of water 
supplies protected under Sec.  817.40 of this chapter.


Sec.  784.23  What information must I include in plans for the 
monitoring of groundwater, surface water, and the biological condition 
of streams during and after mining?

    (a) Groundwater monitoring plan--(1) General requirements. Your 
permit application must include a groundwater monitoring plan adequate 
to evaluate the impacts of the mining operation on groundwater in the 
proposed permit and adjacent areas and to determine in a timely manner 
whether corrective action is needed to prevent the operation from

area. The plan must--
    (i) Identify the parameters to be monitored.
    (ii) Specify the sampling frequency for each parameter.
    (iii) Establish a sufficient number of appropriate monitoring 
locations to evaluate the accuracy of the findings in the PHC 
determination, to identify adverse trends, and to determine, in a 
timely fashion, whether corrective action is needed to prevent material 
damage to the hydrologic balance outside the permit area. At a minimum, 
the plan must include--
    (A) For each aquifer above or immediately below the coal seam to be 
mined, monitoring sites located upgradient and downgradient of the 
proposed operation at a distance sufficiently close to the underground 
mine workings to detect changes as the mining operation progresses. The 
plan must include a schedule and map for moving these sites as the 
underground workings advance.
    (B) Monitoring wells in any existing underground mine workings that 
would have a direct hydrological connection to the proposed operation.
    (C) At least one monitoring well to be located in the mine pool 
after mine closure.

condition of perennial and intermittent streams within the permit and 
adjacent areas.
    (C) Prevent material damage to the hydrologic balance outside the 
permit area.
    (v) Describe how the water samples will be collected, preserved, 
stored, transmitted for analysis, and analyzed in accordance with the 
sampling, analysis, and reporting requirements of paragraphs (a) and 
(b) of Sec.  777.13 of this chapter.
    (2) Parameters--(i) General criteria for selection of parameters. 
The plan must provide for the monitoring of parameters that could be 
affected by the proposed operation if those parameters relate to the--
    (A) Findings and predictions in the PHC determination prepared 
under Sec.  784.20 of this part.
    (B) Biological condition of perennial and intermittent streams and 
other surface-water bodies that receive discharges from groundwater 
within the proposed permit and adjacent areas.
    (C) Suitability of the groundwater for existing and reasonably 
foreseeable uses.
    (D) Suitability of the groundwater to support the premining and 
postmining land uses.
    (ii) Minimum requirements. At a minimum, the plan must require that 
the following parameters be measured at each location every three 
months, with data submitted to the regulatory authority at the same 
frequency:
    (A) Major anions, including, at a minimum, bicarbonate, chloride, 
and sulfate.
    (B) Major cations, including, at a minimum, calcium, magnesium, 
potassium, and sodium.
    (C) The cation-anion balance of the parameters sampled in 
paragraphs (a)(2)(ii)(A) and (B) of this section, plus any cation or 
anion that constitutes a significant percentage of the total ionic 
charge balance.

    (E) Arsenic.
    (F) Cadmium.
    (G) Copper.
    (H) Hot acidity.
    (I) Nitrogen.
    (J) pH.
    (K) Selenium.
    (L) Specific conductance corrected to 25 [deg]C.
    (M) Total alkalinity.
    (N) Total dissolved solids.
    (O) Total iron.
    (P) Total manganese.
    (Q) Zinc.
    (R) Water levels, discharge rates, or yield rates.
    (S) Any parameter listed in Sec.  784.19(d) of this part, if 
detected by the sampling conducted under that paragraph.
    (T) Any other parameters of local significance, as determined by 
the regulatory authority, based upon the information and analyses 
required under Sec. Sec.  784.19 through 784.21 of this part.
    (3) Regulatory authority review and action. (i) Upon completing the 
technical review of the application, the regulatory authority may 
require that you revise the plan to increase the frequency of 
monitoring, to require monitoring of additional parameters, or to 
require monitoring at additional locations, if the additional 
requirements would contribute to protection of the hydrologic balance.
    (ii) After completing preparation of the cumulative hydrologic 
impact assessment required under Sec.  784.21 of this part, the 
regulatory authority must reconsider the adequacy of the monitoring 
plan and require that you make any necessary changes. At a minimum, the 
plan must require monitoring of all parameters for which the regulatory 
authority has established material damage criteria pursuant to the 
cumulative hydrologic impact assessment.
    (4) Exception. If you can demonstrate, on the basis of the PHC 
determination prepared under Sec.  784.20 of this part or other 
available information that a particular water-bearing stratum in the 
proposed permit and adjacent areas has no existing or foreseeable use 
for agricultural or other human purposes or for fish and wildlife 
purposes and does not serve as an aquifer that significantly ensures 
the hydrologic balance within the cumulative impact area, the 
regulatory authority may waive monitoring of that stratum.

restored to a condition capable of supporting the uses that it was 
capable of supporting before any mining.
    (F) Cause the total volume of flow from the reclaimed area, during 
every season of the year, to vary in a way that would preclude any 
existing or reasonably foreseeable use of surface water or groundwater 
or any designated use of surface water under section 101(a) or 303(c)

the structures are consistent with and proportional to the needs of the 
postmining land use.
    (2) The amount of bond required for the permit under part 800 of 
this chapter must include the cost of removing the structure and 
reclaiming the land upon which it was located to a condition capable of 
supporting the premining uses. The bond must include the cost of 
restoring the site to its approximate original contour in accordance 
with Sec.  817.102 of this chapter and establishing native vegetation 
in accordance with Sec.  817.111 of this chapter.
    (3) The reclamation plan submitted under Sec.  784.12 of this part 
must specify that if a structure is not in use as part of the approved 
postmining land use by the end of the revegetation responsibility 
period specified in Sec.  817.115 of this chapter, you must remove the 
structure and reclaim the land upon which it was located by restoring 
the approximate original contour in accordance with Sec.  817.102 of 
this chapter and establishing native vegetation in accordance with 
Sec.  817.111 of this chapter.

intermittent, and ephemeral streams. (i) If you propose to conduct an 
activity identified in paragraph (b)(1) of this section, you must 
propose to establish a riparian corridor at least 100 feet wide on each 
side of the stream as part of the reclamation process following the 
completion of mining activities within that corridor. The corridor 
width must be measured horizontally on a line perpendicular to the 
stream beginning at the bankfull elevation or, if there are no 
discernible banks, the centerline of the active channel.
    (ii) You must use native species, including species adapted to and 
suitable for planting in riparian zones within that corridor, to 
revegetate disturbed areas within the corridor required under paragraph 
(b)(3)(i) of this section. For areas that are forested at the time of 
application or that would revert to forest under conditions of natural 
succession, you must use native trees and shrubs to meet this 
requirement.
    (iii) Paragraph (b)(3)(i) of this section does not apply to--
    (A) Prime farmland historically used for cropland;
    (B) Situations in which revegetation would be incompatible with an 
approved postmining land use that is implemented during the 
revegetation responsibility period before final bond release under 
Sec.  800.42(d) of this chapter; or
    (C) Streams buried beneath an excess spoil fill or a coal mine 
waste disposal facility under paragraph (d) of this section.
    (c) What additional requirements apply to an application that 
proposes to mine through or divert a perennial, intermittent, or 
ephemeral stream?--(1) Postmining drainage pattern. The postmining 
drainage pattern of perennial, intermittent, and ephemeral stream 
channels that you propose to restore after the completion of mining 
must be similar to the premining drainage pattern, unless the 
regulatory authority approves a different pattern to--
    (i) Ensure stability;
    (ii) Prevent or minimize downcutting of reconstructed stream 
channels; or
    (iii) Promote enhancement of fish and wildlife habitat.
    (2) Mining through or diverting a perennial or intermittent stream. 
If you propose to mine through or divert a perennial or intermittent 
stream, you must--
    (i) Comply with the requirements of paragraphs (a) through (c)(1) 
of this section.
    (ii) Demonstrate that there is no reasonable alternative that would 
avoid mining through or diverting the stream.
    (iii) Design the operation to minimize the extent to which the 
stream will be mined through or diverted.
    (iv) Demonstrate that you can restore the form and ecological 
function of the affected stream segment, as required by Sec.  817.57(b) 
of this chapter, using the techniques in the proposed reclamation plan.
    (A) Those techniques must include the selective placement of low-
permeability materials in the backfill or fill and associated stream 
channels to create the aquitards necessary to support streamflow when 
the goal is to reestablish a perennial or intermittent stream, unless 
you can demonstrate an alternative method of restoring perennial or 
intermittent streamflow.
    (B) You must include a separate bond calculation for the cost of 
restoring the ecological function of the affected stream segment. You 
must post a surety bond, a collateral bond, or a combination of surety 
and collateral bonds to cover that cost before the regulatory authority 
may issue the permit.
    (v) Comply with the following stream-channel restoration and 
stream-channel diversion design requirements:
    (A) Designs for permanent stream-channel diversions, temporary 
stream-channel diversions that will remain in use for 2 or more years, 
and stream channels to be restored after the completion of mining must 
adhere to design techniques that will restore or approximate the 
premining characteristics of the original stream channel to promote the 
recovery and enhancement of the aquatic habitat and to minimize adverse 
alteration of stream channels on and off the site, including channel 
deepening or enlargement. The premining characteristics of the original 
stream channel include, but are not limited to, the baseline stream 
pattern, profile, dimensions, substrate, habitat, and natural 
vegetation growing in the riparian zone. For temporary stream-channel 
diversions that will remain in use for 2 or more years, the vegetation 
proposed for planting in the riparian zone need not include species 
that would not reach maturity until after the diversion is removed.
    (B) The designed hydraulic capacity of all temporary and permanent 
stream-channel diversions must be at least equal to the hydraulic 
capacity of the unmodified stream channel immediately upstream of the 
diversion, but no greater than the hydraulic capacity of the unmodified 
stream channel immediately downstream from the diversion.
    (C) All temporary and permanent stream-channel diversions must be 
designed so that the combination of channel, bank, and flood-plain 
configuration is adequate to pass safely the peak runoff of a 10-year, 
6-hour precipitation event for a temporary diversion and a 100-year, 6-
hour precipitation event for a permanent diversion.
    (vi) Submit a certification from a qualified registered 
professional engineer that the designs for all stream-channel 
diversions and all stream channels to be restored after the completion 
of mining meet the design requirements of this section and any 
additional design criteria established by the regulatory authority. 
This certification may be limited to the location, dimensions, and 
physical characteristics of the stream channel; it need not include 
restoration of ecological function.
    (d) What requirements apply to an application to construct an 
excess spoil fill or coal mine waste disposal facility in a perennial 
or intermittent stream?--(1) Applicability. (i) If you propose to 
construct an excess spoil fill under Sec.  784.35 of this part or a 
coal mine waste disposal facility under Sec.  784.25(d) of this part, 
you must comply with the

[[Page 44633]]

requirements of paragraph (d)(2) of this section in place of the 
requirements of paragraph (b)(2) of this section whenever the fill or 
disposal facility would encroach upon any part of a perennial or 
intermittent stream.
    (2) Application requirements. If you propose to construct an excess 
spoil fill or coal mine waste disposal facility of the nature described 
in paragraph (d)(1) of this section, your application must demonstrate 
that--
    (i) The operation has been designed to minimize the amount of 
excess spoil or coal mine waste generated.
    (ii) After evaluating all potential upland locations in the 
vicinity of the proposed operation, there is no practicable alternative 
that would avoid placement of excess spoil or coal mine waste in a 
perennial or intermittent stream.
    (iii) To the extent possible using the best technology currently 
available, the proposed excess spoil fill or coal mine waste disposal 
facility has been designed to minimize--
    (A) Placement of excess spoil or coal mine waste to be placed in a 
perennial or intermittent stream.
    (B) Adverse impacts on fish, wildlife, and related environmental 
values.
    (iv) The fish and wildlife enhancement plan submitted under Sec.  
784.16 of this part includes measures that would fully and permanently 
offset any long-term adverse impacts that the fill, refuse pile, or 
coal mine waste impoundment would have on fish, wildlife, and related 
environmental values within the footprint of the fill, refuse pile, or 
impoundment.
    (v) The excess spoil fill or coal mine waste disposal facility has 
been designed in a manner that will not cause or contribute to a 
violation of water quality standards or result in the formation of 
toxic mine drainage.
    (vi) The revegetation plan submitted under Sec.  784.12(g) of this 
part requires reforestation of the completed excess spoil fill if the 
land is forested at the time of application or if it would revert to 
forest under conditions of natural succession.
    (e) What are the regulatory authority's responsibilities?--(1) 
Standards for restoration of the ecological function of a stream. (i) 
The regulatory authority must establish objective standards for 
determining when the ecological function of a restored or permanently-
diverted perennial or intermittent stream has been restored.
    (ii) In establishing standards under paragraph (e)(1)(i) of this 
section, the regulatory authority must coordinate with the Clean Water 
Act permitting authority to ensure compliance with all Clean Water Act 
requirements.
    (iii) The standards established under paragraph (e)(1)(i) of this 
section must comply with Sec.  817.57(b)(2) of this chapter.
    (2) Finding. The regulatory authority may not approve an 
application that includes any activity identified under paragraph 
(b)(1) of this section unless it first makes a specific written finding 
that you have fully satisfied all applicable requirements of this 
section. The finding must be accompanied by a detailed explanation of 
the rationale for the finding.


Sec.  784.29  What information must I include in the surface-water 
runoff control plan?

    Your application must contain a surface-water runoff control plan 
that includes the following--
    (a)(1) An explanation of how you will handle surface-water runoff 
in a manner that will prevent peak discharges from the proposed permit 
area, both during and after mining and reclamation, from exceeding the 
premining peak discharge from the same area for the same-size 
precipitation event. You must use the appropriate regional Natural 
Resources Conservation Service synthetic storm distribution to estimate 
peak discharges.
    (2) The explanation in paragraph (a)(1) of this section must 
consider the findings in the determination of the probable hydrologic 
consequences of mining prepared under Sec.  784.20 of this part.
    (b) A surface-water runoff monitoring and inspection program that 
will provide sufficient precipitation and stormwater discharge data for 
the proposed permit area to evaluate the effectiveness of the surface-
water runoff control practices under paragraph (a) of this section. The 
surface-water runoff monitoring and inspection program must specify 
criteria for monitoring, inspection, and reporting consistent with 
Sec.  817.34(d) of this chapter. The program must contain a monitoring-

    (9) You have demonstrated that the operation will not damage 
natural watercourses within the proposed permit and adjacent areas. You 
may meet this requirement by demonstrating that the proposed operation 
will comply with all of the following requirements:
    (i) The proposed operation will not increase the amount or 
concentration of parameters of concern in discharges to groundwater and 
surface water from the proposed permit area, when compared to the 
discharges that would occur if the operation were designed to adhere to 
approximate original contour restoration requirements.
    (ii) The proposed operation will not result in changes in the size 
or frequency of peak flows from the proposed permit area that would 
cause an increase in damage from flooding, when compared to the impacts 
that would occur if the operation were designed to adhere to 
approximate original contour restoration requirements.
    (iii) The total volume of flow from the proposed permit area, 
during every season of the year, will not vary in a way that would 
adversely affect any existing or reasonably foreseeable use of surface 
water or groundwater or any designated use of surface water under 
section 101(a) or 303(c) of the Clean Water Act.
    (10) The revegetation plan proposed under Sec.  780.12(g) of this 
chapter requires that those portions of the proposed permit area that 
are forested at the time of application or that would revert to forest 
under conditions of natural succession be revegetated using native tree 
and understory species to the extent that this requirement is not 
inconsistent with attainment of the proposed postmining land use.
    (11) The bond posted for the permit under part 800 of this chapter 
includes an amount equal to the cost of regrading the site to its 
approximate original contour and revegetating the regraded land in the 
event that the approved postmining land use is not implemented before 
expiration of the revegetation responsibility period under Sec.  
816.115 of this chapter.
    (12) The proposed operation complies with all other requirements of 
the regulatory program.
    (c) Permit marking. The regulatory authority must clearly mark the 
permit as including mountaintop removal mining operations. The permit 
must specifically identify the acreage and location of the lands on 
which mountaintop removal mining operations will occur within the 
permit area.
    (d) Subsequent permit reviews. (1) The regulatory authority must 
review each permit issued under this section in accordance with Sec.  
774.10(a)(2) of this chapter.
    (2) The regulatory authority may modify the terms and conditions of 
a permit for mountaintop removal mining at any time if it determines 
that more stringent measures are necessary to insure that the operation 
is conducted in compliance with the requirements of the regulatory 
program.

28. Revise Sec.  785.16 to read as follows:


Sec.  785.16  What special provisions apply to proposed variances from 
approximate original contour restoration requirements for steep-slope 
mining?

    (a) Application and approval requirements. The regulatory authority 
may issue a permit for non-mountaintop removal steep-slope surface coal 
mining operations that includes a variance from the approximate 
original contour restoration requirements in Sec. Sec.  816.102 and 
816.105 of this chapter, as referenced in Sec.  816.107 of this 
chapter, or Sec.  817.102 of this chapter, as referenced in Sec.  
817.107 of this chapter, for all or a portion of the permit area. The 
permit may contain this variance only if the regulatory authority 
finds, in

[[Page 44637]]

writing, that you, the applicant, have demonstrated compliance with the 
following requirements on the basis of a complete application:
    (1) After reclamation, the lands within the proposed permit area to 
which the variance would apply will be suitable for an industrial, 
commercial, residential, or public (including recreational facilities) 
postmining land use.
    (2) The alternative postmining land use requirements of Sec.  
780.24(b) or Sec.  784.24(b) of this chapter have been met.
    (3) After consultation with the appropriate land use planning 
agencies, if any, the proposed use is shown to constitute an equal or 
better economic or public use.
    (4) Federal, state, and local government agencies with an interest 
in the proposed land use have an adequate period in which to review and 
comment on the proposed use.
    (5) A qualified registered professional engineer has certified that 
the operation has been designed in conformance with professional 
standards established to assure the stability, drainage, and 
configuration necessary for the intended use of the site.
    (6) The highwall will be completely backfilled with spoil material 
in a manner that results in a static factor of safety of at least 1.3, 
using standard geotechnical analysis methods.
    (7) Only the amount of spoil that is necessary to achieve the 
postmining land use, ensure the stability of spoil retained on the 
bench, and meet all other requirements of this chapter will be placed 
off the mine bench. All spoil not retained on the bench will be placed 
in accordance with Sec. Sec.  816.71 and 816.74 or Sec. Sec.  817.71 
and 817.74 of this chapter.
    (8) The variance will not result in the construction of a fill in a 
perennial or intermittent stream.
    (9) The proposed operation will improve the condition of the 
watershed of lands within the proposed permit and adjacent areas when 
compared either with the condition of the watershed before the proposed 
operation or with the condition that would exist if the site were mined 
and restored to the approximate original contour. The condition of the 
watershed will be deemed improved only if you demonstrate that the 
following criteria will be met, relative to one of the situations 
described in the preceding sentence:
    (i) The amount or concentration of total suspended solids or other 
parameters of concern in discharges to groundwater or surface water 
from the proposed permit area will be reduced.
    (ii) Flood hazards within the watershed containing the proposed 
permit area will be diminished by reduction of the size or frequency of 
peak-flow discharges from precipitation events or thaws.
    (iii) The total volume of flow from the proposed permit area, 
during every season of the year, will not vary in a way that would 
adversely affect any existing or reasonably foreseeable use of surface 
water or groundwater or any designated use of surface water under 
section 101(a) or 303(c) of the Clean Water Act.
    (iv) The proposed operation will result in a lesser adverse impact 
on the aquatic ecology of the cumulative impact area than would occur 
if the area to be mined was restored to its approximate original 
contour.
    (v) The impact on perennial and intermittent streams within the 
proposed permit and adjacent areas will be less than the impact that 
would occur if the area to be mined was restored to its approximate 
original contour. The fish and wildlife enhancement measures proposed 
and approved under Sec.  780.16 or Sec.  784.16 of this chapter may be 
considered in making this determination.
    (vi) The appropriate state environmental agency has approved the 
plan.
    (10)(i) The owner of the surface of the lands within the proposed 
permit area has knowingly requested, in writing, as part of the 
application, that a variance be granted.
    (ii) The request must be made separately from any surface owner 
consent given for the operations under Sec.  778.15 of this chapter and 
it must show an understanding that the variance could not be granted 
without the surface owner's request.
    (iii) The surface owner has not and will not receive any monetary 
compensation, item of value, or other consideration in exchange for 
requesting the variance.
    (11) The proposed deviations from the premining surface 
configuration are necessary and appropriate to achieve the approved 
postmining land use.
    (12) The revegetation plan proposed under Sec. Sec.  780.12(g) or 
784.12(g) of this chapter requires the use of native tree and 
understory species to revegetate all portions of the permit area that 
are forested at the time of application or that would revert to forest 
under conditions of natural succession. This requirement does not apply 
to--
    (i) Permanent impoundments, roads, and other impervious surfaces to 
be retained following the completion of mining and reclamation.
    (ii) Those portions of the permit area covered by the variance, but 
only to the extent that compliance with this requirement would be 
inconsistent with attainment of the postmining land use.
    (13) The bond posted for the permit under part 800 of this chapter 
includes an amount equal to the cost of regrading the site to its 
approximate original contour and revegetating the regraded land in the 
event that the approved postmining land use is not implemented before 
expiration of the revegetation responsibility period under Sec.  
816.115 or Sec.  817.115 of this chapter.
    (b) Regulatory authority responsibilities. (1) The regulatory 
authority must specifically mark any permit that contains an approved 
variance from approximate original contour restoration requirements.
    (2) The regulatory authority must review each permit incorporating 
a variance under this section in accordance with Sec.  774.10(a)(2) of 
this chapter.
    (3) The regulatory authority may modify the terms and conditions of 
a permit incorporating a variance under this section at any time if it 
determines that more stringent measures are necessary to ensure that 
the operations are conducted in compliance with the requirements of the 
regulatory program.
    (4) The regulatory authority may grant variances in accordance with 
this section only if it has promulgated specific rules to govern the 
granting of variances in accordance with the provisions of this section 
and any necessary, more stringent requirements.
    (5) Before approving a variance in accordance with this section, 
the regulatory authority must find and document in writing that the 
requirements of paragraph (a)(10) of this section have been met.

Sec.  785.25  What special provisions apply to proposed operations on 
lands eligible for remining?

    (a) This section applies to you if you intend to apply for a permit 
to conduct surface coal mining operations on lands eligible for 
remining, as that term is defined in Sec.  701.5 of this chapter.
    (b)(1) Your application must comply with all applicable 
requirements of this subchapter.
    (2) In addition, to be eligible under the provisions of Sec.  
773.13 of this chapter concerning unanticipated events or conditions at 
remining sites, the application must--
    (i) To the extent possible, if not otherwise addressed in the 
permit

[[Page 44638]]

application, identify potential environmental and safety problems that 
could reasonably be anticipated to occur as a result of prior mining 
activities within the proposed permit area. This identification must be 
based on a due diligence investigation that includes visual 
observations, a record review of past mining operations at or near the 
site, environmental sampling, and any other relevant available 
information, including data from prior mining activities and remining 
operations on similar sites.
    (ii) With regard to potential environmental and safety problems 
referred to in paragraph (b)(1)(i) of this section, describe the 
measures that will be taken to ensure that the applicable reclamation 
requirements of the regulatory program can and will be met.

Sec.  800.1  Scope and purpose.

    This part sets forth the minimum requirements for filing and 
maintaining bonds, financial assurances, and liability insurance 
policies for surface coal mining and reclamation operations under 
regulatory programs in accordance with the Act.


Sec.  800.4  Regulatory authority responsibilities.

    (a) The regulatory authority must prescribe and furnish forms for 
filing performance bonds and financial assurances.
    (b) The regulatory authority must prescribe by regulation terms and 
conditions for performance bonds, financial assurances, and liability 
insurance policies.
    (c) The regulatory authority must determine the amount of the bond 
for each area to be bonded, in accordance with Sec.  800.14 of this 
part. The regulatory authority also must adjust the bond amount as 
acreage in the permit area is revised or when other relevant conditions 
change, in accordance with Sec.  800.15 of this part. In addition, the 
regulatory authority must determine the amount of financial assurance 
required under Sec.  800.18 of this part and adjust it as provided in 
that section.
    (d) The regulatory authority may accept a self-bond if the 
permittee meets the requirements of Sec.  800.23 of this part and any 
additional requirements in the regulatory program.
    (e) The regulatory authority must release liability under a bond or 
financial assurance instrument in accordance with Sec. Sec.  800.40 
through 800.44 of this part.
    (f) If the conditions specified in Sec.  800.50 of this part occur, 
the regulatory authority must take appropriate action to cause all or 
part of a bond or financial assurance to be forfeited in accordance 
with procedures of that section.
    (g) The regulatory authority must require in the permit that 
adequate bond and financial assurance coverage be in effect at all 
times. Except as provided in Sec.  800.30(b), operating without 
adequate bond or financial assurance is a violation of a condition of 
these rules and the permit.


Sec.  800.5  Definitions.

    Collateral bond means an indemnity agreement in a sum certain 
executed by the permittee as principal which is supported by the 
deposit with the regulatory authority of one or more of the following:
    (1) A cash account, which shall be the deposit of cash in one or 
more federally-insured or equivalently protected accounts, payable only 
to the regulatory authority upon demand, or the deposit of cash 
directly with the regulatory authority.
    (2) Negotiable bonds of the United States, a state, or a 
municipality, endorsed to the order of, and placed in the possession 
of, the regulatory authority.
    (3) Negotiable certificates of deposit, made payable or assigned to 
the regulatory authority and placed in its possession or held by a 
federally-insured bank.
    (4) An irrevocable letter of credit of any bank organized or 
authorized to transact business in the United States, payable only to 
the regulatory authority upon presentation.
    (5) A perfected, first-lien security interest in real property in 
favor of the regulatory authority.

[[Page 44639]]

Sec.  800.9  What requirements apply to alternative bonding systems?

    (a) OSMRE may approve an alternative bonding system as part of a 
state or federal regulatory program if the system will achieve the 
following objectives and purposes of the bonding program:
    (1) The alternative must assure that the regulatory authority will 
have available sufficient money to complete the reclamation plan for 
any areas which may be in default at any time, except as provided in 
paragraphs (c) and (d) of this section.
    (2) The alternative must provide a substantial economic incentive 
for the permittee to comply with all reclamation provisions.
    (b) The alternative bonding system will apply in lieu of the 
requirements of Sec. Sec.  800.12 through 800.23 of this part, with 
appropriate conforming modifications to the bond release provisions of 
Sec. Sec.  800.40 through 800.44 of this part and the bond forfeiture 
provisions of Sec.  800.50 of this part, to the extent specified in the 
regulatory program and the terms of approval under part 732 of this 
chapter.
    (c) An alternative bonding system may be structured to include only 
certain phases of mining and reclamation under Sec.  800.42 of this 
part, provided that the other phases of mining and reclamation are 
covered by one of the forms of bond listed in Sec.  800.12 of this 
part.
    (d) The following obligations of the permittee are not eligible for 
coverage by an alternative bonding system:
    (1) Restoration of the ecological function of a stream under 
Sec. Sec.  780.28 and 816.57 or Sec. Sec.  784.28 and 817.57 of this 
chapter.
    (2)(i) Treatment of long-term discharges that come into existence 
after the effective date of paragraph (d) of this section, unless, upon 
discovery of the discharge, the permittee contributes an amount 
sufficient to cover all costs that the regulatory authority estimates 
that the alternative bonding system will incur to treat the discharge 
for as long as the discharge requires active or passive treatment to 
meet Clean Water Act standards or the water quality requirements of 
this chapter. The alternative bonding system must place that amount in 
a separate account available only for treatment of the discharge for 
which the contribution is made. Otherwise, consistent with Sec.  800.18 
of this part, the permittee must post a financial assurance, a 
collateral bond, or a combination thereof to cover this obligation.
    (ii) Long-term discharges that came into existence before the 
effective date of paragraph (d) of this section will continue to be 
covered by any applicable state alternative bonding system unless the 
regulatory authority amends its program to specifically establish an 
earlier effective date. The permittee of a site with a discharge 
subject to paragraph (d)(2)(ii) of this section must contribute to the 
alternative bonding system an amount sufficient to cover all costs that 
the alternative bonding system will incur to treat the discharge in 
perpetuity.


Sec.  800.10  Information collection.

    In accordance with 44 U.S.C. 3501 et seq., the Office of Management 
and Budget (OMB) has approved the information collection requirements 
of this part and assigned it control number 1029-xxxx. The regulatory 
authority uses information collected under this part to ensure that 
bond, insurance, and financial assurance instruments are valid and meet 
all requirements of section 509 of SMCRA, which requires that persons 
planning to conduct surface coal mining operations first post a 
performance bond to guarantee fulfillment of all reclamation 
obligations under the approved permit. The regulatory authority also 
uses information collected under this part to ensure compliance with 
the bond release requirements and procedures of section 519 of SMCRA, 
the liability insurance requirements of section 507(f) of SMCRA, and 
bond forfeiture requirements and procedures. Persons planning to 
conduct surface coal mining operations must respond to obtain a 
benefit. A federal agency may not conduct or sponsor, and you are not 
required to respond to, a collection of information unless it displays 
a currently valid OMB control number.


Sec.  800.11  When and how must I file a bond?

    (a) After approving a permit application submitted under subchapter 
G of this chapter, the regulatory authority may not issue the permit 
until you, the permit applicant, file one of the following:
    (1) A performance bond or bonds for the entire permit area;
    (2) A cumulative bond schedule and the performance bond required 
for full reclamation of the initial area to be disturbed; or
    (3) An incremental bond schedule and the performance bond required 
for the first increment in the schedule.
    (b) The bond or bonds that you file under paragraph (a) of this 
section must be--
    (1) In an amount determined under Sec.  800.14 of this part.
    (2) On a form prescribed and furnished by the regulatory authority.
    (3) Made payable to the regulatory authority.
    (4) Conditioned upon the faithful performance of all the 
requirements of the regulatory program and the permit, including the 
reclamation plan.
    (c) If the bond or bonds filed under paragraph (a) of this section 
cover only an identified increment of land within the permit area upon 
which you will initiate and conduct surface coal mining operations 
during the initial term of the permit, you must--
    (1) Identify the initial and successive areas or increments for 
bonding on the permit application map submitted under part 780 or part 
784 of this chapter and specify the bond amount to be provided for each 
area or increment.
    (2) Ensure that independent increments are of sufficient size and 
configuration to provide for efficient reclamation operations should 
reclamation by the regulatory authority become necessary pursuant to 
Sec.  800.50 of this part.
    (3) File additional bond or bonds with the regulatory authority to 
cover each succeeding increment before you initiate and conduct surface 
coal mining operations on that increment.
    (d) You may not disturb any surface area or extend any vertical 
underground mine shaft or other vertical underground mine opening for 
which a performance bond is required before the regulatory authority 
accepts the performance bond required for that area or extension.


Sec.  800.12  What form of bond is acceptable?

    (a) The regulatory authority must prescribe the form of the 
performance bond.
    (b) Except as provided in paragraphs (c) through (e) of this 
section, the regulatory authority may allow the permittee to post any 
of the following forms of bond:
    (1) A surety bond;
    (2) A collateral bond;
    (3) A self-bond; or
    (4) A combination of any of these forms of performance bond.
    (c) An alternative bonding system approved under Sec.  800.9 of 
this part may allow the permittee to post either more or fewer forms of 
bond than those listed in paragraph (b) of this section.
    (d) The regulatory authority may accept only a financial assurance 
or a collateral bond to guarantee treatment of a long-term discharge 
under Sec.  800.18 of this part.
    (e) The regulatory authority may accept only a surety bond, a 
collateral bond, or a combination thereof to

[[Page 44640]]

guarantee restoration of the ecological function of a stream under 
Sec. Sec.  780.28(c), 784.28(c), 816.57(b), and 817.57(b) of this 
chapter.


Sec.  800.13  What is the liability period for a bond?

    (a)(1) Liability under the performance bond will be for the 
duration of the surface coal mining and reclamation operation and for a 
period coincident with the period of extended responsibility for 
successful revegetation under Sec.  816.115 or Sec.  817.115 of this 
chapter or until achievement of the reclamation requirements of the 
regulatory program and the permit, whichever is later.
    (2) With the approval of regulatory authority, a bond may be posted 
and approved to guarantee specific phases of reclamation within the 
permit area, provided that the sum of phase bonds posted equals or 
exceeds the total amount required under Sec. Sec.  800.14 and 800.15 of 
this part. The scope of work to be guaranteed and the liability assumed 
under each phase bond must be specified in detail.
    (b) Isolated and clearly defined portions of the permit area 
requiring extended liability may be separated from the original area 
and bonded separately with the approval of the regulatory authority.
    (1) These areas must be limited in extent and not constitute a 
scattered, intermittent, or checkerboard pattern of failure.
    (2) With the approval of the regulatory authority, the permittee 
may apply the provisions of paragraph (b) of this section to the amount 
of bond posted to guarantee restoration of a stream's ecological 
function under Sec. Sec.  780.28 and 816.57 or Sec. Sec.  784.28 and 
817.57 of this chapter.
    (3) The regulatory authority must include any necessary access 
roads or routes in the area under extended liability.
    (c) If the regulatory authority approves a long-term, intensive 
agricultural postmining land use, the revegetation responsibility 
period specified under Sec.  816.115 or Sec.  817.115 of this chapter 
will start on the date of initial planting for the long-term 
agricultural use.
    (d)(1) The bond liability of the permittee includes only those 
actions that the permittee is required to perform under the permit and 
regulatory program to complete the reclamation plan for the area 
covered by the bond.
    (2) The bond does not cover implementation of an alternative 
postmining land use approved under Sec.  780.24(b) or Sec.  784.24(b) 
of this chapter, but which is beyond the control of the permittee. 
Except as provided in Sec.  785.16(a)(13) of this chapter, the 
permittee is responsible only for restoring the site to conditions 
capable of supporting the approved postmining land use.
    (3) Bond liability for prime farmland includes meeting the 
productivity requirement specified in Sec.  800.42(c) of this part.
    (4) Bond liability for treatment or abatement of long-term 
discharges is specified in Sec.  800.18 of this part.


Sec.  800.14  How will the regulatory authority determine the amount of 
bond required?

    (a) The regulatory authority must determine the amount of the bond 
required for each area to be bonded, based upon, but not limited to--
    (1) The requirements of the permit, including the reclamation plan.
    (2) The probable difficulty of reclamation, giving consideration to 
the topography, geology, hydrology, and revegetation potential of the 
permit area and the biological condition of perennial and intermittent 
streams within the permit and adjacent areas.
    (3) The estimated reclamation costs submitted by the permit 
applicant.
    (b)(1) The amount of the bond must be sufficient to assure the 
completion of the reclamation plan if the work has to be performed by a 
third party under contract with the regulatory authority in the event 
of forfeiture.
    (2) The calculations used to determine the amount of bond required 
under paragraph (b)(1) of this section must specifically identify the 
amount of bond needed to guarantee restoration of a stream's ecological 
function under Sec. Sec.  780.28 and 816.57 or Sec. Sec.  784.28 and 
817.57 of this chapter. The permittee may elect to either post a 
separate bond for this amount or incorporate that amount into the bond 
posted for the entire permit or increment.
    (c) When the permit includes a variance from approximate original 
contour restoration requirements under Sec.  785.16 of this chapter, 
the amount of the bond must be sufficient to restore the disturbed area 
to the approximate original contour if the approved postmining land use 
is not implemented by the end of the applicable revegetation 
responsibility period under Sec.  816.115 or Sec.  817.115 of this 
chapter.
    (d) The amount of financial assurance required for treatment of 
long-term discharges must be determined in accordance with Sec.  800.18 
of this part.
    (e) The total bond initially posted for the entire area under one 
permit may not be less than $10,000.
    (f) The permittee's financial responsibility under Sec.  817.121(c) 
of this chapter for repairing or compensating for material damage 
resulting from subsidence may be satisfied by the liability insurance 
policy required under Sec.  800.60 of this part.


Sec.  800.15  When must the regulatory authority adjust the bond amount 
and when may I request adjustment of the bond amount?

    (a) The regulatory authority must adjust the amount of the bond 
required and, if needed, the terms of the acceptance when--
    (1) The area requiring bond coverage increases or decreases.
    (2) The unit cost or scope of future reclamation changes as a 
result of technological advances, revisions to the operation or 
reclamation plans in the permit, or external factors.
    (i) The regulatory authority may specify periodic times or set a 
schedule for reevaluating and adjusting the bond amount to fulfill this 
requirement.
    (ii) The permittee may request at any time that the regulatory 
authority reduce the amount of the performance bond based upon 
submission of evidence that the permittee's method of operation or 
other circumstances will reduce the estimated unit costs for the 
regulatory authority to reclaim the bonded area.
    (iii) The regulatory authority may not use the provisions of this 
section to reduce the amount of the performance bond to reflect changes 
in the cost of reclamation resulting from completion of activities 
required under the reclamation plan. Bond reduction for completed 
reclamation activities must comply with the bond release requirements 
and procedures of Sec. Sec.  800.40 through 800.44 of this part.
    (b) The regulatory authority must--
    (1) Notify the permittee, the surety, and any person with a 
property interest in collateral who has requested notification under 
Sec.  800.21(f) of this part of any proposed adjustment to the bond 
amount; and
    (2) Provide the permittee an opportunity for an informal conference 
on the adjustment.
    (c) Bond reductions under paragraph (a) of this section are not 
subject to the bond release requirements and procedures of Sec. Sec.  
800.40 through 800.44 of this part.
    (d) In the event that an approved permit is revised in accordance 
with subchapter G of this chapter, the regulatory authority must review 
the bond amount for adequacy and, if necessary, require adjustment of 
the bond amount to conform to the permit as revised. This provision may 
not be used to reduce bond amounts under the circumstances described in 
paragraph (a)(2)(iii) of this section.

[[Page 44641]]

    (e) The regulatory authority must require that appropriate bond or 
financial assurance be posted in accordance with Sec.  800.18 of this 
part whenever a discharge that will require long-term treatment is 
identified.
    (f) The regulatory authority may not reduce the bond amount when 
the permittee does not restore the approximate original contour as 
required or when the reclamation plan was improperly modified to 
reflect the level of reclamation completed rather than the level of 
reclamation required under the regulatory program.


Sec.  800.16  What are the general terms and conditions of the bond?

    (a) The performance bond must be in an amount determined by the 
regulatory authority as provided in Sec.  800.14 of this part.
    (b) The performance bond must be payable to the regulatory 
authority.
    (c) The performance bond must be conditioned upon faithful 
performance of all the requirements of the regulatory program and the 
approved permit, including completion of the reclamation plan.
    (d) The duration of the bond must be for the time provided in Sec.  
800.13 of this part.
    (e) The bond must provide a mechanism for a bank, surety, or other 
responsible financial entity to give prompt notice to the regulatory 
authority and the permittee of any action filed alleging the insolvency 
or bankruptcy of the surety, the bank, or other responsible financial 
entity, or alleging any violations that would result in suspension or 
revocation of the firm's charter or license to do business.


Sec.  800.17  [Reserved]


Sec.  800.18  What special provisions apply to financial guarantees for 
treatment of long-term discharges?

    (a) Applicability. (1) This section applies whenever surface coal

or facilities regulated under this title result in a discharge to 
surface water or groundwater that--
    (i) Requires treatment; and
    (ii) Continues or may reasonably be expected to continue after the 
completion of mining, backfilling, grading, and the establishment of 
revegetation.
    (2) This section also applies whenever information available to the 
regulatory authority documents that a discharge of the nature described 
in paragraph (a)(1) of this section will develop in the future, 
provided that the quantity and quality of the future discharge can be 
determined with reasonable probability.
    (b) Type of financial instruments allowed. (1) Except as provided 
in Sec.  800.9(d)(2) of this part, the permittee must post either a 
financial assurance instrument or a collateral bond to guarantee 
treatment or abatement of postmining discharges.
    (2) If the permittee elects to post a collateral bond under 
paragraph (b)(1) of this section, the amount of the bond must include 
the cost of treating the discharge during the time required to collect 
and liquidate the bond and convert the proceeds to a financial 
instrument that will generate funds in an amount sufficient to cover 
future treatment costs and associated administrative expenses.
    (3) Operations with discharges in states with an approved 
alternative bonding system must comply with the requirements of Sec.  
800.9(d)(2) of this part.
    (c) Discharge treatment standards for cost calculation purposes. 
Calculation of the amount of financial assurance or collateral bond 
required under this section must include the cost of treating the 
discharge to meet any applicable numerical standards or limits that are 
in effect at the time that the regulatory authority issues an order 
requiring posting of a financial assurance or bond, provided that the 
numerical standards or limits are established in--
    (1) The permit issued under subchapter G of this chapter;
    (2) A permit or authorization issued under the Clean Water Act; or
    (3) Regulations implementing the Clean Water Act.
    (d) Requirements for financial assurances. (1) The trust fund or 
annuity must be established in a manner that guarantees that sufficient 
moneys will be available when needed to pay for--
    (i) Treatment of discharges in perpetuity, unless the permittee 
demonstrates, and the regulatory authority finds, based upon available 
evidence, that treatment will be needed for a lesser time, either 
because the discharge will attenuate or because its quality will 
improve. The regulatory authority may accept arrangements that allow 
the permittee to build the amount of the trust fund or annuity over 
time, provided--
    (A) The permittee continues to treat the discharge during that 
time; and
    (B) The regulatory authority retains all performance bonds posted 
for the permit until the trust fund or annuity reaches a self-
sustaining level as determined by the regulatory authority.
    (ii) Maintenance, renovation, and replacement of treatment and 
support facilities as needed.
    (iii) Final reclamation of the sites upon which treatment 
facilities are located and areas used in support of those facilities.

consistent with long-term historical rates of return for similar 
investments.
    (4) The trust fund or annuity must be in a form approved by the 
regulatory authority and contain all terms and conditions required by 
the regulatory authority.
    (5) The trust fund or annuity must irrevocably establish the 
regulatory authority as the beneficiary of the trust fund or of the 
proceeds from the annuity for the purpose of treating mine drainage or 
other mining-related discharges to protect the environment and users of 
surface water.
    (6) The trust fund or annuity must provide that disbursement of 
money from the trust fund or annuity may be made only upon written 
authorization of the regulatory authority or according to a schedule 
established in the agreement accompanying the trust fund or annuity.

issuing an annuity must be one of the following:
    (i) A national bank chartered by the Office of the Comptroller of 
the Currency.
    (ii) An operating subsidiary of a national bank chartered by the 
Office of the Comptroller of the Currency.
    (iii) A bank or trust company chartered by the state in which the 
operation is located.
    (iv) An insurance company licensed or authorized to do business in 
the state in which the operation is located or designated by the 
pertinent regulatory body of that state as an eligible surplus lines 
insurer.
    (v) Any other financial institution or company with trust powers 
and with offices located in the state in which the operation is

a

[[Page 44642]]

trust fund or annuity may occur only upon the demise of the trustee or 
the company issuing the annuity or as specified by the regulatory 
authority upon a determination that one of the following situations 
exists--
    (1) No further treatment or other reclamation measures are 
necessary, in which case paragraph (h) of this section will apply.
    (2) A satisfactory replacement bond or financial assurance has been 
posted in accordance with paragraph (g) of this section.
    (3) The terms of the trust fund or annuity establish conditions for 
termination and those conditions have been met.
    (4) The trustee's administration of the trust fund or annuity is 
unsatisfactory to the regulatory authority, in which case the permittee 
or the regulatory authority must procure a new trustee.
    (f) Regulatory authority review and adjustment of amount of 
financial assurance. (1) The regulatory authority must establish a 
schedule for reviewing the performance of the trustee, the adequacy of 
the trust fund or annuity, and the accuracy of the assumptions upon 
which the trust fund or annuity is based. This review must occur on at 
least an annual basis.
    (2) The regulatory authority must require that the permittee 
provide additional resources to the trust fund or annuity whenever the 
review conducted under paragraph (f)(1) of this section or any other 
information available to the regulatory authority at any time 
demonstrates that the financial assurance is no longer adequate to meet 
the purpose for which it was established.
    (g) Replacement of financial assurance. With the approval of the 
regulatory authority, a financial assurance may be replaced in 
accordance with the provisions of Sec.  800.30(a) of this part.
    (h) Release of liability. Release of reclamation liabilities and 
obligations under financial assurances is subject to the applicable

part.
    (i) Effect of financial assurance on release of bond. The permittee 
may apply for, and the regulatory authority may approve, release of any 
bonds posted for the permit or permit increment for which the 
regulatory authority has approved a financial assurance under this 
section, provided that the permittee and the regulatory authority 
comply with the bond release requirements and procedures in Sec. Sec.  
800.40 through 800.44 of this part. This provision applies only if the 
following conditions exist--
    (1) The financial assurance is both in place and fully funded.
    (2) The permit or permit increment fully meets all applicable 
reclamation requirements, with the exception of the discharge and the 
presence of associated treatment and support facilities.
    (3) The financial assurance will serve as the bond for reclamation 
of the portion of the permit area required for postmining water 
treatment facilities and access to those facilities.


Sec.  800.20  What additional requirements apply to surety bonds?

    (a) A surety bond must be executed by the permittee and a corporate 
surety licensed to do business in the state where the operation is 
located.
    (b) Surety bonds must be noncancellable during their terms, except

    (4) The regulatory authority may not accept an individual 
certificate of deposit in an amount in excess of the maximum amount 
insured by the Federal Deposit Insurance Corporation.
    (b) Letters of credit are subject to the following conditions:

other suitable form of bond at least 30 days before the letter's 
expiration date.
    (3) The letter of credit must be payable to the regulatory 
authority upon demand, in part or in full, upon receipt from the 
regulatory authority of a notice of forfeiture issued in accordance 
with Sec.  800.50 of this part.
    (c) Real property posted as a collateral bond must meet the 
following conditions:
    (1) The applicant or permittee must grant the regulatory authority 
a first mortgage, first deed of trust, or perfected first-lien security 
interest in real property with a right to sell or otherwise dispose of 
the property in the event of forfeiture under Sec.  800.50 of this 
part.
    (2) In order for the regulatory authority to evaluate the adequacy 
of the real property offered to satisfy collateral requirements, the 
applicant or permittee must submit a schedule of the real property to 
be mortgaged or pledged to secure the obligations under the indemnity

appraisal conducted by a certified appraiser; and
    (iii) Proof of possession and title to the real property.
    (3) The property may include land that is part of the permit area. 
However, land pledged as collateral for a bond under this section may

this section.
    (d) Cash accounts are subject to the following conditions:
    (1) The regulatory authority may authorize the permittee to 
supplement the bond through the establishment of a cash account in one 
or more federally-insured or equivalently protected accounts made 
payable upon demand to, or deposited directly with, the regulatory 
authority. The total bond, including the cash account, may not be less 
than the amount determined under Sec.  800.14 of this part, as modified 
by any adjustments under Sec.  800.15 of this part, less any amounts 
released under Sec. Sec.  800.40 through 800.44 of this part.

Federal Deposit Insurance Corporation.
    (e)(1) The estimated bond value of all collateral posted as 
assurance under this section is subject to a margin, which is the ratio 
of bond value to market value, as determined by the regulatory 
authority. The margin must reflect legal and liquidation fees, as well 
as value depreciation, marketability, and fluctuations that might 
affect the net cash available to the regulatory authority to complete 
reclamation.
    (2)(i) The regulatory authority may evaluate the bond value of 
collateral at any time.
    (ii) The regulatory authority must evaluate the bond value of 
collateral as part of the permit renewal process.

value of the collateral.
    (f) Persons who have an interest in collateral posted as a bond, 
and who desire notification of actions pursuant to the bond, must

with less than 5 years of continuous operation to qualify under this 
requirement, if each member of the joint venture or syndicate has been

date of application.
    (ii) When calculating the period of continuous operation, the 
regulatory authority may exclude past periods of interruption to the

an applicant's self-bond from a parent corporation guarantor, if the 
guarantor meets the conditions of paragraphs (b)(1) through (4) of this 
section as if it were the applicant. This written guarantee will be 
referred to as a ``corporate guarantee.'' The terms of the corporate 
guarantee must provide for the following:
    (i) If the applicant fails to complete the reclamation plan, the 
guarantor must do so or the guarantor will be liable under the 
indemnity agreement to provide funds to the regulatory authority

amount.
    (ii) The corporate guarantee will remain in force unless the 
guarantor sends notice of cancellation by certified mail to the 
applicant and to the regulatory authority at least 90 days in advance 
of the cancellation date, and the regulatory authority accepts the

    (iii) The cancellation may be accepted by the regulatory authority 
if the applicant obtains suitable replacement bond before the 
cancellation date or if the lands for which the self-bond, or portion 
thereof, was accepted have not been disturbed.
    (2) The regulatory authority may accept a written guarantee for an 
applicant's self-bond from any corporate guarantor, whenever the 
applicant meets the conditions of paragraphs (b)(1), (2), and (4) of 
this section, and the guarantor meets the conditions of paragraphs 
(b)(1) through (4) of this section. This written guarantee will be 
referred to as a ``non-parent corporate guarantee.'' The terms of this 
guarantee must provide for compliance with the conditions of paragraphs 
(c)(1)(i) through (iii) of this section. The regulatory authority may 
require the applicant to submit any information specified in paragraph 
(b)(3) of this section in order to determine the financial capabilities 
of the applicant.
    (d)(1) For the regulatory authority to accept an applicant's self-
bond, the total amount of the outstanding and proposed self-bonds of 
the applicant for surface coal mining and reclamation operations may 
not exceed 25 percent of the applicant's tangible net worth in the 
United States.
    (2) For the regulatory authority to accept a corporate guarantee, 
the total amount of the parent corporation guarantor's present and 
proposed self-bonds and guaranteed self-bonds for surface coal mining

    (1) The indemnity agreement must be executed by all persons and 
parties who are to be bound by it, including the parent corporation 
guarantor. It must bind each party jointly and severally.
    (2) Corporations applying for a self-bond, and parent and non-
parent corporations guaranteeing an applicant's self-bond, must submit 
an indemnity agreement signed by two corporate officers who are 
authorized to bind their corporations. A copy of the authorization must 
be provided to the regulatory authority along with an affidavit 
certifying that the agreement is valid under all applicable federal and 
state laws. In addition, the guarantor must provide a copy of the 
corporate authorization demonstrating that the corporation may 
guarantee the self-bond and execute the indemnity agreement.
    (3) If the applicant is a partnership, joint venture or syndicate, 
the agreement must bind each partner or party who has a beneficial 
interest, directly or indirectly, in the applicant.
    (4) Pursuant to Sec.  800.50, the applicant and the parent or non-
parent corporate guarantor will be required to complete the approved 
reclamation plan for the lands in default or to pay to the regulatory 
authority an amount necessary to complete the approved reclamation 
plan, not to exceed the bond amount. If permitted under State law, the 
indemnity agreement, when under forfeiture, will operate as a judgment 
against those parties liable under the indemnity agreement.
    (f) A regulatory authority may require self-bonded applicants and 
parent and non-parent corporate guarantors to submit an update of the 
information required under paragraphs (b)(3) and (4) of this section 
within 90 days after the close of each fiscal year following the 
issuance of the self-bond or corporate guarantee.
    (g) If at any time during the period when a self-bond is posted, 
the financial conditions of the applicant or the parent or non-parent 
corporate guarantor change so that the criteria of paragraphs (b)(3) 
and (d) of this section are not satisfied, the permittee must notify 
the regulatory authority immediately and post an alternate form of bond 
in the same amount as the self-bond within 90 days. Should the 
permittee fail to post an adequate substitute bond, the provisions of 
Sec.  800.30(b) of this part will apply.


Sec.  800.30  When may I replace a bond or financial assurance 
instrument and when must I do so?

    (a) Replacement upon request of permittee. (1) The regulatory 
authority may allow you, the permittee, to replace existing bonds and 
financial assurance instruments with other bonds and financial 
assurance instruments that provide equivalent coverage.
    (2) If the proposed replacement bond under paragraph (a) of this 
section is a surety bond, the regulatory authority may decline to 
accept the replacement bond if, in the judgment of the regulatory 
authority, the new surety does not have adequate reinsurance or other 
resources sufficient to cover the default of one or more mining 
companies for which the surety has provided bond coverage.
    (3) The regulatory authority may not release any existing 
performance bond or financial assurance instrument until you have 
submitted, and the regulatory authority has approved, an acceptable 
replacement.
    (b) Replacement by order of the regulatory authority. (1) Upon the 
incapacity of a bank, surety, or other responsible financial entity by 
reason of bankruptcy, insolvency, or suspension or revocation of a 
charter or license, you will be deemed to be without bond coverage and 
you must promptly notify the regulatory authority.
    (2) Upon receipt of notification under Sec.  800.16(e) of this part 
or from you under paragraph (b)(1) of this section, the regulatory 
authority must issue an order requiring that you submit replacement 
bond or financial assurance coverage within a reasonable time, not to 
exceed 90 days.
    (3) If you do not post adequate bond or financial assurance by the 
end of the time allowed, the regulatory authority must issue a notice 
of violation requiring that you post adequate bond or financial 
assurance coverage. If you are actively conducting surface coal mining 
operations, the notice of violation also must require that you cease 
coal extraction and reclaim the site in accordance with the provisions 
of Sec.  816.132 or Sec.  817.132 of this chapter.

during seasons authorized by the regulatory authority. The times or 
seasons appropriate for the evaluation of certain types of reclamation 
will be established in either the regulatory program or your permit.
    (b) What must I include in my application for bond release? You 
must include--
    (1) The application form and information required by the regulatory 
authority.

Sec. Sec.  817.35 through 817.37 of this chapter.
    (vii) The name and address of the regulatory authority to which 
written comments, objections, or requests for public hearings and 
informal conferences on the bond release application may be submitted 
pursuant to Sec.  800.44 of this section.
    (3) Copies of letters that you have sent to adjoining property 
owners, local governmental bodies, planning agencies, sewage and water 
treatment authorities, and water companies in the locality of the 
surface coal mining and reclamation operation, notifying them of your 
intention to seek release of the bond.
    (4) A notarized statement certifying that all applicable 
reclamation activities have been accomplished in accordance with the 
requirements of the regulatory program and the approved reclamation 
plan. You must submit a separate certification for each application and 
each phase of bond release.

Sec.  800.41  How will the regulatory authority process my application 
for bond release?

    (a)(1) Upon receipt of a complete application for bond release, the 
regulatory authority will, within 30 days, or as soon thereafter as 
weather conditions permit, conduct an inspection of the site and an 
evaluation of the reclamation work performed and the reclamation work 
remaining.
    (2) A complete application is one that includes all items required 
under Sec.  800.40 of this part.
    (3) The evaluation will consider, among other factors, the degree 
of difficulty to complete any remaining reclamation, whether pollution 
of surface and subsurface water is occurring, the probability of future 
occurrence of such pollution, and the estimated cost of abating such 
pollution.
    (b)(1) The regulatory authority will notify the surface owner, 
agent, or lessee before conducting the inspection and will offer that 
person an opportunity to participate with the regulatory authority in 
making the inspection.
    (2) The regulatory authority may arrange with you to allow access 
to the permit area, upon request by any person with an interest in bond 
release, for the purpose of gathering information relevant to the 
proceeding.


Sec.  800.42  What are the criteria for bond release?

    (a) General requirements. (1) Except as provided in paragraphs 
(a)(2) through (5) of this section, the regulatory authority may 
release all or part of the bond for the permit area or an increment 
thereof if the regulatory authority is satisfied that you have 
accomplished the required reclamation for the permit area or increment 
in accordance with paragraphs (b) through (d) of this section.
    (2) The regulatory authority may not release any bond under this 
section if, after an evaluation of the monitoring data submitted under 
Sec. Sec.  816.35 through 816.37 or Sec. Sec.  817.35 through 817.37 of 
this chapter, it determines that adverse trends exist that may result 
in material damage to the hydrologic balance outside the permit area.
    (3) If a discharge requiring long-term treatment exists either on 
the permit area or at a point that is hydrologically connected to the 
permit area, you must post a separate bond or financial assurance under 
Sec.  800.18 of this part before any portion of the existing bond for 
the permit area may be released.
    (4) If the permit area or increment includes a variance from 
restoration of the approximate original contour under Sec.  785.16 of 
this chapter, the portion of the bond described in Sec.  785.16(a)(13) 
of this chapter may not be released in whole or in part until the 
approved postmining land use is implemented or until the site is 
restored to the approximate original contour and revegetated in 
accordance with Sec. Sec.  816.111 and 816.116 or Sec. Sec.  817.111 
and 817.116 of this chapter.
    (5) The bond amount described in Sec.  780.24(d)(2) or Sec.  
784.24(d)(2) of this chapter may not be released either until the 
structure is in use as part of the postmining land use or until the 
structure is removed and the site upon which it was located is 
reclaimed in accordance with part 816 or part 817 of this chapter.
    (6) The regulatory authority must consider the results of the 
evaluation conducted under Sec.  800.41(a)(3) of this part when 
determining the amount of bond to release.
    (b) Phase I reclamation. (1) The regulatory authority may release a 
maximum of 60 percent of the bond for a bonded area after you complete 
Phase I reclamation for that area in accordance with the approved 
reclamation plan. Phase I reclamation consists of backfilling, grading, 
and drainage control. It includes restoration of the form of perennial 
and intermittent stream segments under Sec.  816.57 or Sec.  817.57 of 
this chapter. Soil replacement is optional for this phase.
    (2) The amount of bond that the regulatory authority retains after 
Phase I release must be adequate to ensure that the regulatory 
authority will have sufficient funds for a third party to complete the 
remaining portion of the reclamation plan, including restoration of the 
ecological function of perennial and intermittent streams under Sec.  
816.57 or Sec.  817.57 of this chapter and completion of any fish and 
wildlife enhancement measures required in the permit in accordance with 
Sec.  780.16 or Sec.  784.16 of this chapter, in the event of 
forfeiture.
    (c) Phase II reclamation. (1) The regulatory authority may release 
an additional amount of bond after you complete Phase II reclamation, 
which consists of soil replacement (if not accomplished as part of 
Phase I reclamation) and successfully establishing revegetation on the 
area in accordance with the approved reclamation plan. The regulatory 
authority must establish standards defining successful establishment of 
vegetation for purposes of this paragraph.
    (2) The amount of bond that the regulatory authority retains after 
Phase II release must be sufficient to cover the cost of having a third 
party reestablish revegetation for the revegetation responsibility 
period under Sec.  816.115 or Sec.  817.115 of this chapter. In 
addition, it must be adequate to ensure that the regulatory authority 
will have sufficient funds for a third party to complete the remaining 
portion of the reclamation plan, including restoration of the 
ecological function of perennial and intermittent streams under Sec.  
816.57 or Sec.  817.57 of this chapter and completion of any fish and 
wildlife enhancement measures required in the permit in accordance with 
Sec.  780.16 or Sec.  784.16 of this chapter, in the event of 
forfeiture.
    (3) The regulatory authority may not release any part of the bond 
under paragraph (c)(1) of this section if the lands to which the 
release would apply are contributing suspended solids to streamflow or 
runoff outside the permit area in excess of the requirements set by 
subchapter K of this chapter.
    (4) The regulatory authority may not release any part of the bond 
under paragraph (c)(1) of this section until soil productivity for any 
prime farmland on the area to which the release would apply has 
returned to levels of yield equivalent to those of nonmined land of the 
same soil type in the surrounding area under equivalent management 
practices as determined from the soil survey performed under part 823 
of this chapter.
    (5) When the regulatory authority has approved retention of a silt 
dam as a permanent impoundment under Sec.  816.49(b) or Sec.  817.49(b) 
of this chapter, the regulatory authority may approve Phase II bond 
release for the area of the impoundment if the requirements of Sec.  
816.56 or Sec.  817.56 of this chapter have been met and provisions for 
sound future maintenance by the operator or the landowner have been 
made with the regulatory authority.
    (d) Phase III reclamation. (1) The regulatory authority must 
release the remaining portion of the bond upon the completion of Phase 
III reclamation, which consists of successful completion of all surface 
coal mining and reclamation activities and expiration of the 
revegetation responsibility period under Sec.  816.115 or Sec.  817.115 
of this chapter.
    (2) The regulatory authority may not fully release any bond under 
provisions of this section until all applicable reclamation 
requirements of the regulatory program and the permit are fully met. 
Among other things, those requirements include restoration of the 
ecological function of perennial and intermittent streams under Sec.  
816.57 or Sec.  817.57 of this chapter and completion of any fish and 
wildlife enhancement measures required in the permit in

[[Page 44646]]

accordance with Sec.  780.16 or Sec.  784.16 of this chapter.


Sec.  800.43  When and how must the regulatory authority provide 
notification of its decision on a bond release application?

    (a) The regulatory authority will provide written notification of 
its decision on your bond release application to you, the surety (if 
applicable), any other persons with an interest in bond collateral who 
have requested notification under Sec.  800.21(f) of this part, persons 
who filed objections in writing, and objectors who were a party to the 
hearing proceedings, if any. The regulatory authority will provide this

    (c) When any application for total or partial bond release is filed 
with the regulatory authority, the regulatory authority must notify the 
municipality in which the surface coal mining operation is located by 
certified mail at least 30 days prior to the release of all or a 
portion of the bond.


Sec.  800.44  Who may file an objection to a bond release application 
and how must the regulatory authority respond to an objection?

    (a)(1) Any person with a valid legal interest that might be 
adversely affected by release of the bond, or the responsible officer 
or head of any federal, state, or local governmental agency with 
jurisdiction by law or special expertise with respect to any 
environmental, social, or economic impact involved in the operation or 
which is authorized to develop and enforce environmental standards with 
respect to those operations, has the right to file written objections 
to the proposed bond release with the regulatory authority within 30 
days after the last publication of the notice required by Sec.  
800.40(b)(2) of this part.
    (2) If written objections are filed and a hearing is requested, the 
regulatory authority must inform all interested parties of the time and 
place of the hearing, and hold a public hearing within 30 days after 
receipt of the request for the hearing. The regulatory authority must 
advertise the date, time, and location of the public hearing in a 
newspaper of general circulation in the locality for two consecutive 
weeks.
    (3) The public hearing must be held in the locality of the surface 
coal mining operation for which bond release is sought, at the location 
of the regulatory authority office, or at the state capital, at the 
option of the objector.
    (b)(1) For the purpose of the hearing under paragraph (a) of this 
section, the regulatory authority has the authority to administer 
oaths, subpoena witnesses or written or printed material, compel the 
attendance of witnesses or the production of materials, and take 
evidence including, but not limited to, inspection of the land affected 
and other surface coal mining operations carried on by the applicant in 
the general vicinity.
    (2) A verbatim record of each public hearing must be made, and a 
transcript must be made available on the motion of any party or by 
order of the regulatory authority.
    (c) Without prejudice to the right of an objector or the applicant 
for bond release, the regulatory authority may hold an informal 
conference as provided in section 513(b) of the Act to resolve written 
objections. The regulatory authority must make a record of the informal 
conference unless waived by all parties, which must be accessible to 
all parties. The regulatory authority also must furnish all parties to 
the informal conference with a written finding based on the informal 
conference, and the reasons for the finding.


Sec.  800.50  When and how will a bond be forfeited?

    (a) If a permittee or operator refuses or is unable to conduct 
reclamation of an unabated violation, if the terms of the permit are 
not met, or if the permittee or operator defaults on the conditions 
under which the bond was accepted, the regulatory authority must take 
the following action to forfeit all or part of a bond or bonds for any 
permit area or an increment of a permit area:
    (1) Send written notification by certified mail, return receipt 
requested, to the permittee and the surety on the bond, if any, 
informing them of the determination to forfeit all or part of the bond, 
including the reasons for the forfeiture and the amount to be 
forfeited. The amount must be based on the estimated total cost of 
achieving the reclamation plan requirements.
    (2) Advise the permittee and surety, if applicable, of the 
conditions under which forfeiture may be avoided. Those conditions may 
include, but are not limited to--
    (i) Agreement by the permittee or another party to perform 
reclamation operations in accordance with a compliance schedule that 
meets the conditions of the permit, the reclamation plan, and the 
regulatory program and a demonstration that the party has the ability 
to satisfy the conditions; or
    (ii) The regulatory authority may allow a surety to complete the 
reclamation plan, or the portion of the reclamation plan applicable to 
the bonded phase or increment if the surety can demonstrate an ability 
to complete the reclamation in accordance with the approved reclamation 
plan. Except where the reclamation work performed meets the criteria 
for partial bond release under Sec.  800.42 of this part, no surety 
liability may be released until successful completion of all 
reclamation under the terms of the permit, including applicable 
liability periods of Sec.  800.13 of this part.
    (b) In the event forfeiture of the bond is required by this 
section, the regulatory authority shall--
    (1) Proceed to collect the forfeited amount as provided by 
applicable laws for the collection of defaulted bonds or other debts if 
actions to avoid forfeiture have not been taken, or if rights of 
appeal, if any, have not been exercised within a time established by 
the regulatory authority, or if such appeal, if taken, is unsuccessful.
    (2) Use funds collected from bond forfeiture to complete the 
reclamation plan, or portion thereof, on the permit area or increment, 
to which bond coverage applies.
    (c) Upon default, the regulatory authority may cause the forfeiture 
of any and all bonds deposited to complete reclamation for which the 
bonds were posted. Unless specifically limited, as provided in Sec.  
800.11(c) of this part, bond liability will extend to the entire permit 
area under conditions of forfeiture.
    (d)(1) In the event the estimated amount forfeited is insufficient 
to pay for the full cost of reclamation, the permittee or operator is 
liable for remaining costs. The regulatory authority may complete, or 
authorize completion of, reclamation of the bonded area and may recover 
from the permittee or operator all costs of reclamation in excess of 
the amount forfeited.
    (2) In the event the amount of performance bond forfeited is more 
than the amount necessary to complete reclamation, the regulatory 
authority

[[Page 44647]]

must return the unused funds to the party from whom they were 
collected.


Sec.  800.60  What liability insurance must I carry?

    (a) The regulatory authority must require the applicant to submit 
as part of its permit application a certificate issued by an insurance 
company authorized to do business in the United States certifying that 
the applicant has a public liability insurance policy in force for the 
surface coal mining and reclamation operations for which the permit is 
sought. The policy must provide for personal-injury and property-damage 
protection in an amount adequate to compensate any persons injured or 
property damaged as a result of the surface coal mining and reclamation 
operations, including the use of explosives, and who are entitled to 
compensation under the applicable provisions of state law. Minimum 
insurance coverage for bodily injury and property damage is $300,000 
for each occurrence and $500,000 aggregate.
    (b) The policy must be maintained in full force during the life of 
the permit or any renewal thereof and the liability period necessary to 
complete all reclamation operations under this chapter.
    (c) The policy must include a rider requiring that the insurer 
notify the regulatory authority whenever substantive changes are made 
in the policy, including any termination or failure to renew.
    (d) The regulatory authority may accept from the applicant, in lieu 
of a certificate for a public liability insurance policy, satisfactory 
evidence from the applicant that it satisfies applicable state self-
insurance requirements approved as part of the regulatory program and 
the requirements of this section.


Sec.  800.70  What special bonding provisions apply to anthracite 
operations in Pennsylvania?

    (a) All provisions of this subchapter apply to bonding and insuring 
anthracite surface coal mining and reclamation operations in 
Pennsylvania except that--
    (1) The regulatory authority must determine specified bond limits 
in accordance with applicable provisions of Pennsylvania statutes, 
rules and regulations adopted thereunder, and implementing policies of 
the Pennsylvania regulatory authority.
    (2) The period of liability for responsibility under each bond must 
be established for those operations in accordance with applicable laws 
of the Commonwealth of Pennsylvania, rules and regulations adopted 
thereunder, and implementing policies of the Pennsylvania regulatory 
authority.
    (b) Upon amendment of the Pennsylvania permanent regulatory program 
with respect to specified bond limits and the period of revegetation 
responsibility for anthracite surface coal mining and reclamation 
operations, any person engaging in or seeking to engage in those 
operations must comply with additional regulations the Secretary may 
issue as are necessary to meet the purposes of the Act.

    (b) If the approved permit identifies an exploration hole, drilled 
hole, borehole, well, or other exposed underground opening for use to 
monitor groundwater or to return coal processing waste or water to 
underground workings, you must temporarily seal the hole or opening 
before use and protect it during use by installing barricades, fences, 
or other protective devices approved by the regulatory authority. You 
must periodically inspect these devices and maintain them in good 
operating condition.
    (c) You may retain and transfer a drilled hole or groundwater 
monitoring well for use as a water well under the conditions 
established in Sec.  816.39 of this part.
    (d) Except as provided in paragraph (c) of this section, you must 
permanently close each exploration hole, drilled hole, borehole, well, 
or underground opening that mining activities uncover or expose within 
the permit area, unless the regulatory authority--
    (1) Approves use of the hole, well, or opening for water monitoring 
purposes; or
    (2) Authorizes other management of the hole or well.
    (e)(1) Except as provided in paragraph (c) of this section, you 
must cap, seal, backfill, or otherwise properly manage each shaft, 
drift, adit, tunnel, exploratory hole, entryway or other opening to the 
surface from underground when no longer needed for monitoring or any 
other use that the regulatory authority approves after finding that the 
use will not adversely affect the environment or public health and 
safety.
    (2) Permanent closure measures taken under paragraph (e)(1) of this 
section must be--
    (i) Consistent with Sec.  75.1771 of this title;
    (ii) Designed to prevent access to the mine workings by people, 
livestock, fish and wildlife, and machinery; and

Sec.  816.15  [Reserved]


Sec.  816.22  How must I handle topsoil, subsoil, and other plant 
growth media?

    (a) Removal and salvage. (1) You, the permittee, must separately 
remove and salvage all topsoil and other soil materials identified for 
salvage and use as postmining plant growth media in the soil handling 
plan approved in the permit under Sec.  780.12(e) of this chapter. You 
must complete removal and salvage of these materials from the area to 
be disturbed before any drilling, blasting, mining, or other surface 
disturbance takes place on that area.
    (2) The regulatory authority may choose not to require the removal 
of topsoil and other soil materials for minor disturbances that--
    (i) Occur at the site of small structures, such as power poles, 
signs, or fence lines; or
    (ii) Will not destroy the existing vegetation and will not cause 
erosion.
    (b) Storage. (1) You must segregate and, except as provided in 
paragraph (b)(3) of this section, stockpile the materials removed under 
paragraph (a) of this section when it is impractical to

[[Page 44649]]

redistribute those materials promptly on regraded areas.
    (2) Stockpiled materials must--
    (i) Be selectively placed on a stable site within the permit area;
    (ii) Be protected from contaminants and unnecessary compaction that 
would interfere with revegetation;
    (iii) Be protected from wind and water erosion through prompt 
establishment and maintenance of an effective, quick-growing, non-
invasive vegetative cover or through other measures approved by the 
regulatory authority; and
    (iv) Not be moved until required for redistribution unless approved 
by the regulatory authority.
    (3) When stockpiling of organic matter and soil materials removed 
under paragraphs (a) and (f) of this section would be detrimental to 
the quality or quantity of those materials, you may temporarily 
redistribute those soil materials on an approved site within the permit 
area to enhance the current use of that site until the materials are 
needed for later reclamation, provided that--
    (i) Temporary redistribution will not permanently diminish the 
capability of the topsoil of the host site; and
    (ii) The redistributed material will be preserved in a condition 
more suitable for redistribution than if it were stockpiled.
    (c) Soil substitutes and supplements. When the soil handling plan 
approved in the permit in accordance with Sec.  780.12(e) of this 
chapter provides for the use of substitutes for or supplements to the 
existing topsoil or subsoil, you must salvage, store, and redistribute 
the overburden materials selected and approved for that purpose in a 
manner consistent with paragraphs (a), (b), and (e) of this section.
    (d) Site preparation. (1) You must minimize grading of backfilled 
areas to avoid compaction of the reconstructed root zone, as specified 
in the soil handling plan approved in the permit in accordance with 
Sec.  780.12(e) of this chapter. Compaction is allowed only to the 
extent necessary to ensure stability and to comply with water-quality 
standards.
    (2) If necessary, you must rip, chisel-plow, or otherwise 
mechanically treat backfilled and graded areas before topsoil 
redistribution to reduce potential slippage of the redistributed 
material and to promote root penetration. You may conduct this 
treatment after soil redistribution if doing so will not harm the 
redistributed material.
    (e) Redistribution. (1) You must redistribute the materials 
removed, salvaged, and, if necessary, stored under paragraphs (a) 
through (c) of this section in a manner that--
    (i) Complies with the soil handling plan developed under Sec.  
780.12(e) of this chapter and approved as part of the permit.
    (ii) Is consistent with the approved postmining land use, contours, 
and surface-water drainage systems.
    (iii) Minimizes compaction of the materials to the extent possible 
and alleviates any excess compaction that may occur.
    (iv) Protects the materials from wind and water erosion before and 
after seeding and planting to the extent necessary to ensure 
establishment of a successful vegetative cover and to avoid causing or 
contributing to a violation of applicable water quality standards.
    (v) Achieves an approximately uniform, stable thickness across the 
regraded area, except that the thickness may vary when consistent with 
the postmining land use and when variations are necessary or desirable 
to achieve specific revegetation goals and ecological diversity, as set 
forth in the revegetation plan developed under Sec.  780.12(g) of this 
chapter and approved as part of the permit.
    (2) You must use a statistically valid sampling technique to 
document that soil materials have been redistributed in the locations 
and depths required by the soil handling plan developed under Sec.  
780.12(e) of this chapter and approved as part of the permit.
    (3) The regulatory authority may choose not to require the 
redistribution of topsoil on the embankments of permanent impoundments 
or on the embankments of roads to be retained as part of the postmining 
land use if it determines that--
    (i) Placement of topsoil on those embankments is inconsistent with 
the requirement to use the best technology currently available to 
prevent sedimentation, and
    (ii) The embankments will be otherwise stabilized.
    (f) Organic matter. (1) You must salvage duff, other organic 
litter, and vegetative materials such as tree tops, small logs, and 
root balls. You may not burn organic matter or bury it in the backfill.
    (2) Except as otherwise provided in paragraph (f)(3) of this 
section, you must redistribute the materials salvaged under paragraph 
(f)(1) of this section across the regraded surface or incorporate them 
into the soil to control erosion, promote growth of vegetation, serve 
as a source of native plant seeds and soil inoculants to speed 
restoration of the soil's ecological community, and increase the 
moisture retention capability of the soil.
    (3) Vegetative debris must be redistributed in accordance with 
paragraph (f)(2) of this section, used for stream restoration purposes, 
or used to construct fish and wildlife habitat enhancement features.

runoff in a manner that will restore the approximate premining recharge 
capacity of the reclaimed area as a whole, excluding coal mine waste 
disposal areas and excess spoil fills, so as to allow the movement of 
water into the groundwater system.
    (10) Protect surface-water quality by using the best technology 
currently available to handle earth materials, groundwater discharges, 
and runoff in a manner that--
    (i) Avoids the formation of acid or toxic mine drainage.
    (ii) Prevents additional contribution of suspended solids to 
streamflow or runoff outside the permit area to the extent possible.
    (iii) Otherwise prevents water pollution.

with a 2-year recurrence interval. You must use the appropriate 
regional Natural Resources Conservation Service synthetic storm 
distribution to determine peak flow for a storm with that recurrence 
interval.
    (ii) In areas with an average annual precipitation of 26.0 inches 
or less, a significant event of a size specified by the regulatory 
authority.
    (2) You must prepare a report, which must be certified by a

Sec.  816.38  How must I handle acid-forming and toxic-forming 
materials?

    You, the permittee, must use the best technology currently 
available to handle acid-forming and toxic-forming materials in a 
manner that will avoid the creation of acid or toxic mine drainage into 
surface water and groundwater. At a minimum, you must--
    (a) Identify potential acid-forming and toxic-forming materials in 
overburden strata and the stratum immediately below the lowest coal 
seam to be mined and cover exposed coal seams and the stratum 
immediately beneath the lowest coal seam mined with a layer of 
compacted material with a hydraulic conductivity at least two orders of 
magnitude lower than the hydraulic conductivity of the adjacent less-
compacted spoil to minimize contact and interaction with water.
    (b) Identify the anticipated postmining groundwater level for all 
locations at which you propose to place acid-forming or toxic-forming 
materials.
    (c) Selectively handle and place acid-forming and toxic-forming 
materials within the backfill in accordance with the plan approved in 
the permit under Sec.  780.12(d)(4) of this chapter, unless the permit 
allows placement of those materials in an excess spoil fill or a coal 
mine waste refuse pile. When placing those materials in the backfill, 
you must use one or more of the following techniques, as appropriate 
and as approved in the permit:
    (1) Completely surround acid-forming and toxic-forming materials 
with compacted material with a hydraulic conductivity at least two 
orders of magnitude lower than the hydraulic conductivity of adjacent 
less-compacted spoil.
    (2) Place acid-forming and toxic-forming materials in a location 
below the water table where they will remain fully saturated at all 
times, provided that the permittee demonstrates, and the regulatory 
authority finds in writing in the permit, that complete saturation will 
prevent the formation of acid or toxic leachate.
    (3) Treat or otherwise neutralize acid-forming and toxic-forming 
materials to prevent the formation of acid or toxic mine drainage. This 
technique also may be used in combination with either isolation under 
paragraph (c)(1) of this section or saturation under paragraph (c)(2) 
of this section.
    (d) When approved in the permit, place acid-forming and toxic-
forming materials in an excess spoil fill or a coal mine waste refuse 
pile, using one or both of the following techniques, as appropriate:
    (1) Completely surround acid-forming and toxic-forming materials 
with compacted material with a hydraulic conductivity at least two 
orders of magnitude lower than the hydraulic conductivity of the 
adjacent uncompacted spoil or coal mine waste.
    (2) Treat or otherwise neutralize acid-forming and toxic-forming 
materials to prevent the formation of acid or toxic mine drainage.
    (e) Temporarily store acid-forming and toxic-forming materials only 
if the regulatory authority specifically approves temporary storage as 
necessary and finds in writing in the permit that the proposed storage 
method will protect surface water and groundwater by preventing 
erosion, the formation of polluted runoff, and the infiltration of 
polluted water into aquifers. The regulatory authority must specify a 
maximum time for temporary storage, which may not exceed the period 
until burial first becomes feasible. In addition, storage must not 
result in any risk of water pollution, adverse impacts to the 
biological condition of perennial or intermittent streams, or other 
environmental damage.
    (f) Adhere to disposal, treatment, and storage practices that are 
consistent with other material handling and disposal provisions of this 
chapter.


Sec.  816.39  What must I do with exploratory or monitoring wells when 
I no longer need them?

    (a) Except as provided in paragraph (b) of this section, you, the 
permittee, must permanently seal exploratory or monitoring wells in a 
safe and environmentally sound manner in accordance with Sec.  816.13 
of this part before the regulatory authority may approve full release 
of the bond posted for the land on which the wells are located under 
section Sec.  800.42(d) of this chapter.
    (b) With the prior approval of the regulatory authority, you may 
transfer wells to another party for further use. The conditions of the 
transfer must comply with state and local laws. You will remain 
responsible for the proper

[[Page 44652]]

management of the wells until full release of the bond posted for the 
land on which the wells are located under Sec.  800.42(d) of this 
chapter.


Sec.  816.40  What responsibility do I have to replace water supplies?

    (a) Replacement of adversely-impacted water supplies. (1) You, the 
permittee, must replace the water supply of an owner of interest in 
real property who obtains all or part of his or her supply of water for 
domestic, agricultural, industrial, or other legitimate use from an 
underground or surface source when the water supply has been adversely 
impacted by contamination, diminution, or interruption as a result of 
your surface mining activities.
    (2) The replacement supply must be equivalent to the quantity and 
quality of the premining supply.
    (3) Replacement includes provision of an equivalent water supply 
delivery system and payment of operation and maintenance expenses in 
excess of customary and reasonable delivery costs for the premining 
water supply. If you and the water supply owner agree, the obligation 
to pay operation and maintenance costs may be satisfied by a one-time 
payment in an amount that covers the present worth of the increased 
annual operation and maintenance costs for a period upon which you and 
the water supply owner agree.
    (4) If the affected water supply was not needed for the land use in 
existence at the time of loss, contamination, or diminution, and if the 
supply is not needed to achieve the postmining land use, you may 
satisfy the replacement requirements by demonstrating that a suitable 
alternative water source is available and could feasibly be developed, 
provided you obtain written concurrence from the owner of the affected 
water supply.
    (b) Measures to address anticipated adverse impacts to protected 
water supply losses. For anticipated loss of or damage to a protected 
water supply, you must adhere to the requirements set forth in the 
permit in accordance with Sec.  780.22(b) of this chapter.
    (c) Measures to address unanticipated adverse impacts to protected 
water supplies. For unanticipated loss of or damage to a protected 
water supply, you must--
    (1) Provide an emergency temporary water supply within 24 hours of 
notification of the loss. The temporary supply must be adequate in 
quantity and quality to meet normal household needs.
    (2) Develop and submit a plan for a permanent replacement supply to 
the regulatory authority within 30 days of receiving notice that an 
unanticipated loss of or damage to a protected water supply has 
occurred.
    (3) Provide a permanent replacement water supply within 2 years of 
the date of receiving notice of an unanticipated loss of or damage to a 
protected water supply.
    (d) Basis for determination of adverse impact. The regulatory 
authority must use the baseline hydrologic and geologic information 
required under Sec.  780.19 of this chapter and all other available 
information to determine whether and to what extent the mining 
operation adversely impacted the damaged water supply.


Sec.  816.41  Under what conditions may I discharge water and other 
materials into an underground mine?

    (a) You may not discharge any water or other materials from a 
surface coal mining and reclamation operation into an underground mine 
unless the regulatory authority specifically approves the discharge in 
writing, based upon a demonstration that--
    (1) The discharge will be made in a manner that--
    (i) Minimizes disturbances to the hydrologic balance within the 
permit area;
    (ii) Prevents material damage to the hydrologic balance outside the 
permit area, including the hydrologic balance of the area in which the 
underground mine receiving the discharge is located;
    (iii) Does not adversely impact the biological condition of 
perennial or intermittent streams; and
    (iv) Otherwise eliminates public hazards resulting from surface 
mining activities.
    (2) The discharge will not result in a violation of applicable 
water quality standards or effluent limitations.
    (3)(i) The discharge will be at a known rate and of a quality that 
will meet the effluent limitations for pH and total suspended solids 
referenced in Sec.  816.42 of this part.
    (ii) The regulatory authority may approve discharges of water that 
exceed the effluent limitations for pH and total suspended solids if 
the available evidence indicates that there is no direct hydrologic 
connection between the underground mine and other waters and that those 
exceedances will not be inconsistent with paragraph (a)(1) of this 
section.
    (4) The Mine Safety and Health Administration has approved the 
discharge.
    (5) You have obtained written permission from the owner of the mine 
into which the discharge is to be made and you have provided a copy of 
that authorization to the regulatory authority.
    (b) Discharges are limited to the following materials:
    (1) Water.
    (2) Coal processing waste.

registered professional land surveyor as specified in paragraph 
(a)(11)(iv) of this section, must promptly provide to the regulatory 
authority a certified report that the impoundment has been constructed 
and/or maintained as designed and in accordance with the approved plan 
and this chapter. The report must include a discussion of any 
appearance of instability, any structural weakness or other hazardous 
condition, the depth and elevation of any impounded waters, the 
existing storage capacity, any existing or required monitoring 
procedures and instrumentation, and any other aspects of the structure 
affecting stability.
    (iii) You must retain a copy of the report at or near the minesite.
    (iv) In any state that authorizes land surveyors to prepare and 
certify plans in accordance with Sec.  780.25(a) of this chapter, a 
qualified registered professional land surveyor may inspect any 
temporary or permanent impoundment that does not meet the criteria for 
High Hazard Class or Significant Hazard Class dams in TR-60, or that 
does not meet the criteria of Sec.  77.216(a) of this title, and 
certify and submit the report required by paragraph (a)(11)(ii) of this 
section, except that a qualified registered professional engineer must

must be examined at least quarterly. A qualified person designated by 
the operator must examine impoundments for the appearance of structural 
weakness and other hazardous conditions.
    (13) Emergency procedures. If any examination or inspection 
discloses that a potential hazard exists, the person who examined the 
impoundment must promptly inform the regulatory authority of the 
finding and of the emergency procedures formulated for public 
protection and remedial action. The regulatory authority must be 
notified immediately if adequate procedures cannot be formulated or 
implemented. The regulatory authority then must notify the appropriate 
agencies that other emergency procedures are required to protect the 
public.
    (b) Requirements that apply only to permanent impoundments. A 
permanent impoundment of water may be created if authorized by the 
regulatory authority in the approved permit based upon the following 
demonstration:
    (1) The size and configuration of the impoundment will be adequate 
for its intended purposes.
    (2) The quality of impounded water will be suitable on a permanent 
basis for its intended use and, after reclamation, will meet applicable 
state and federal water quality standards. Discharges from the 
impoundment will meet applicable effluent limitations and will not 
degrade the quality of receiving water below applicable state and 
federal water quality standards.
    (3) The water level will be sufficiently stable and be capable of 
supporting the intended use.
    (4) Final grading will provide for adequate safety and access for 
proposed water users.
    (5) The impoundment will not result in the diminution of the 
quality and quantity of water used by surrounding landowners for 
agricultural, industrial, recreational, or domestic uses.
    (6) The impoundment will be suitable for the approved postmining 
land use.
    (7) Approval of the impoundment will not result in retention of 
spoil piles or ridges that are inconsistent with the definition of 
approximate original contour.
    (8) Approval of the impoundment will not result in the creation of 
an excess spoil fill elsewhere within the permit area.
    (9) The impoundment has been designed with dimensions and other 
characteristics that will enhance fish and wildlife habitat to the 
extent that doing so is not inconsistent with the intended use.
    (c) Requirements that apply only to temporary impoundments that 
rely primarily upon storage. (1) In lieu of meeting the requirements in 
paragraph (a)(9)(i) of this section, the regulatory authority may 
approve an impoundment that relies primarily on storage to control the 
runoff from the design precipitation event when you demonstrate, and a 
qualified registered professional engineer or qualified registered 
professional land surveyor in accordance with Sec.  780.25(a) of this 
chapter certifies, that the impoundment will safely control the design 
precipitation event.
    (2) You must use current prudent engineering practices to safely 
remove the water from an impoundment constructed in accordance with 
paragraph (c)(1) of this section.

[[Page 44656]]

    (3) An impoundment constructed in accordance with paragraph (c)(1) 
of this section must be located where failure would not be expected to 
cause loss of life or serious property damage, unless the impoundment 
meets one of the following exceptions:
    (i) An impoundment that meets the criteria for High Hazard Class or 
Significant Hazard Class dams in TR-60, or that meets the criteria of 
Sec.  77.216(a) of this title, and is designed to control the 
precipitation of the probable maximum precipitation of a 6-hour event, 
or any greater event specified by the regulatory authority.
    (ii) An impoundment not included in paragraph (c)(3)(i) of this 
section that is designed to control the precipitation of the 100-year, 
6-hour event, or any greater event specified by the regulatory 
authority.


Sec.  816.56  How must I rehabilitate sedimentation ponds, diversions, 
impoundments, and treatment facilities after I no longer need them?

    Before abandoning a permit area or seeking bond release, you must 
ensure that all temporary structures are removed and reclaimed, and 
that all permanent sedimentation ponds, diversions, impoundments, and 
treatment facilities meet the requirements of this chapter for 
permanent structures, have been maintained properly, and meet the 
requirements of the approved reclamation plan for permanent structures 
and impoundments. You must renovate these structures if necessary to 
meet the requirements of this chapter and to conform to the approved 
reclamation plan.


Sec.  816.57  What additional performance standards apply to activities 
in, through, or adjacent to perennial or intermittent streams?

    (a)(1) General prohibition. You, the permittee or operator, may not 
conduct surface mining activities in or through a perennial or 
intermittent stream, or that would disturb the surface of land within 
100 feet of a perennial or intermittent stream, unless the regulatory 
authority authorizes you to do so in the permit after making the 
findings required under Sec.  780.28 of this chapter. The 100-foot 
distance must be measured horizontally on a line perpendicular to the 
stream beginning at the bankfull elevation or, if there are no 
discernible banks, the centerline of the active channel.
    (2) Clean Water Act requirements. You may conduct surface mining 
activities in waters of the United States only if you first obtain all 
necessary authorizations, certifications, and permits under the Clean 
Water Act, 33 U.S.C. 1251 et seq.
    (b) Requirements for mining through or diverting perennial or 
intermittent streams--(1) Compliance with permit. If your permit 
authorizes you to mine through or divert a perennial or intermittent 
stream, you must comply with the designs and construction and 
maintenance plans approved in the permit.
    (2) Restoration of form and function. You must restore the form and 
ecological function of the stream segment as expeditiously as 
practicable. You must do so either as part of the construction of a 
permanent stream-channel diversion or as part of the construction of a 
restored stream channel when the area in which the stream was located 
before mining is no longer needed for surface mining activities.
    (i) Form. A restored stream channel or a stream-channel diversion 
need not exactly replicate the channel morphology that existed before 
mining, but, except as provided in paragraph (b)(4) of this section, it 
must have a channel morphology comparable to the premining form of the 
affected stream segment in terms of baseline stream pattern, profile, 
and dimensions, including channel slope, sinuosity, water depth, 
bankfull depth, bankfull width, width of the flood-prone area, and 
dominant in-stream substrate.
    (ii) Function. (A) A stream flowing through a restored stream 
channel or a stream-channel diversion must meet the functional 
restoration criteria established by the regulatory authority under 
Sec.  780.28(e)(1) of this chapter.
    (B) The restored stream need not have precisely the same biological 
condition or biota as the stream segment did before mining, but the 
biological condition of the restored stream must be adequate to support 
the uses of that stream segment that existed before mining and it must 
not preclude attainment of the designated uses of that stream segment 
under section 101(a) or 303(c) of the Clean Water Act before mining.
    (C) The biological condition of the restored stream must be 
determined using a protocol that meets the requirements of Sec.  
780.19(e)(2) of this chapter.
    (D) Populations of organisms used to determine the biological 
condition must be self-sustaining within the restored stream segment.
    (iii) Bond and bond release requirements. (A) The performance bond 
calculations for the operation must include a specific line item for 
restoration of the ecological function of the stream segment, as 
provided in Sec.  800.14(b)(2) of this chapter.
    (B) You must post a surety bond, a collateral bond, or a 
combination of surety and collateral bonds to cover the cost of 
restoration of the ecological function of the stream segment.
    (C) You must demonstrate full restoration of the hydrological form 
of the stream segment before you can qualify for Phase I bond release 
under Sec.  800.42(b)(1) of this chapter.
    (D) You must demonstrate full restoration of the ecological 
function of the stream segment before you can qualify for final bond 
release under Sec.  800.42(d) of this chapter.
    (3) Certification. Upon completion of construction of a stream-
channel diversion or a restored stream channel, you must obtain a 
certification from a qualified registered professional engineer that 
the stream-channel diversion or restored stream channel has been 
constructed in accordance with the design approved in the permit and 
meets all requirements of this section other than the functional 
restoration requirements of paragraph (b)(2)(ii) of this section.
    (4) Special provision for restoration of degraded stream segments. 
If the stream segment to be mined through or diverted is in a degraded 
condition before mining, you must implement measures to enhance the 
form and ecological function of the segment as part of the restoration 
or diversion process.
    (c) Prohibition on placement of sedimentation control structures in 
streams. (1) Except as provided in paragraph (c)(2) of this section, 
you may not construct a sedimentation pond in a perennial or 
intermittent stream or use perennial or intermittent streams as waste 
treatment systems to convey surface runoff from the disturbed area to a 
sedimentation pond.
    (2) The prohibition in paragraph (c)(1) of this section does not 
apply to excess spoil fills or coal mine waste disposal facilities in 
steep-slope areas when use of a perennial or intermittent stream 
segment as a waste treatment system for sediment control or 
construction of a sedimentation pond in a perennial or an intermittent 
stream would have less overall adverse impact on fish, wildlife, and 
related environmental values than construction of diversions and 
sedimentation ponds on slopes above the stream.
    (3) When the circumstances described in paragraph (c)(2) of this 
situation exist, the following requirements apply:
    (i) You must minimize the length of the stream segment used as a 
waste treatment system to the extent possible

[[Page 44657]]

and, when practicable, maintain an undisturbed buffer along that 
segment in accordance with paragraph (a)(1) of this section.
    (ii) You must place the sedimentation pond as close to the toe of 
the excess spoil fill or coal mine waste disposal structure as 
possible.
    (iii) Following the completion of construction and revegetation of 
the fill or coal mine waste disposal structure, you must remove the 
sedimentation pond and restore the stream segment in accordance with 
paragraph (b)(2) of this section.


Sec.  816.59  How must I maximize coal recovery?

    You must conduct surface mining activities so as to maximize the 
utilization and conservation of the coal, while using the best 
appropriate technology currently available to maintain environmental 
integrity, so that reaffecting the land in the future through surface 
coal mining operations is minimized.


Sec.  816.61  Use of explosives: General requirements.

    (a) Compliance with other laws and regulations. You must comply 
with all applicable state and federal laws and regulations governing 
the use of explosives.
    (b) Compliance with blasting schedule. Blasts that use more than 5 
pounds of explosive or blasting agent must be conducted according to

performance standards; and
    (ii) Give direction and on-the-job training to persons who are not 
certified and who are assigned to the blasting crew or who assist in 
the use of explosives.
    (d) Blast design. (1) You must submit an anticipated blast design 
if blasting operations will be conducted within--
    (i) 1,000 feet of any building used as a dwelling, public building, 
school, church, or community or institutional building outside the 
permit area; or
    (ii) 500 feet of an active or abandoned underground mine.
    (2) The blast design may be submitted as part of a permit 
application or, if approved by the regulatory authority, at a later 
date, provided that the design is submitted and approved before 
blasting begins.
    (3) The blast design must contain--
    (i) Sketches of the drill patterns, delay periods, and decking.
    (ii) The type and amount of explosives to be used.
    (iii) Critical dimensions.

and meet the applicable airblast, flyrock, and ground-vibration 
standards in Sec.  816.67 of this part.
    (4) A certified blaster must prepare and sign the blast design.
    (5) The regulatory authority may require changes to the design 
submitted.


Sec.  816.62  Use of explosives: Preblasting survey.

    (a) At least 30 days before initiation of blasting, you must 
notify, in writing, all residents or owners of dwellings or other 
structures located within \1/2\ mile of the permit area how to request 
a preblasting survey.
    (b)(1) A resident or owner of a dwelling or structure within \1/2\ 
mile of any part of the permit area may request a preblasting survey. 
This request must be made, in writing, directly to you or to the 
regulatory authority. If the request is made to the regulatory 
authority, the regulatory authority will promptly notify you.
    (2) You must promptly conduct a preblasting survey of the dwelling 
or structure and promptly prepare a written report of the survey.
    (3) You must conduct an updated survey of any subsequent additions,

requested by the resident or owner.
    (c) You must determine the condition of the dwelling or structure 
and document any preblasting damage and other physical factors that 
could reasonably be affected by the blasting. Structures such as 
pipelines, cables, transmission lines, and cisterns, wells, and other 
water systems warrant special attention; however, the assessment of 
these structures may be limited to surface conditions and other readily 
available data.
    (d)(1) The person who conducted the survey must sign the written 
report of the survey.

    \2\ Applicable to the scaled-distance equation of paragraph 
(d)(3)(i) of this section.

    (ii) You must provide a seismographic record for each blast.
    (3) Scaled-distance equation. (i) You may use the scaled-distance 
equation, W = (D/Ds)2, to determine the allowable charge weight of 
explosives to be detonated in any 8-millisecond period, without seismic 
monitoring, where W = the maximum weight of explosives, in pounds; D = 
the distance, in feet, from the blasting site to the nearest protected 
structure; and Ds = the scaled-distance factor. The regulatory 
authority may initially approve the scaled-distance equation using the 
values for the scaled-distance factor listed in paragraph (d)(2)(i) of 
this section.
    (ii) The regulatory authority may authorize development of a 
modified scaled-distance factor upon receipt of a written request by 
the operator, supported by seismographic records of blasting at the 
minesite. The modified scale-distance factor must be determined such 
that the particle velocity of the predicted ground vibration will not 
exceed the prescribed maximum allowable peak particle velocity of 
paragraph (d)(2)(i) of this section at a 95-percent confidence level.
    (4) Blasting-level chart. (i) You may use the ground-vibration 
limits in Figure 1 to determine the maximum allowable ground vibration.

Sec.  816.71  How must I dispose of excess spoil?

    (a) General requirements. You, the permittee or operator, must 
mechanically transport and place excess spoil in designated disposal 
areas, including approved valley fills and other types of approved 
fills, within the permit area in a controlled manner in compliance with 
the requirements of this section. In general, you must place excess 
spoil in a manner that will--
    (1) Minimize the adverse effects of leachate and surface water 
runoff from the fill on surface water, groundwater, and the biological 
condition of perennial and intermittent streams within the permit and 
adjacent areas.
    (2) Ensure mass stability and prevent mass movement during and 
after construction.
    (3) Ensure that the final surface configuration of the fill is 
suitable for revegetation and the approved postmining land use or uses 
and is compatible with the natural drainage pattern and surroundings.
    (4) Minimize disturbances to, and adverse impacts on, fish, 
wildlife, and related environmental values to the extent possible, 
using the best technology currently available.
    (5) Ensure that the fill will not change the size or frequency of 
peak flows from precipitation events or thaws in a way that would 
result in an increase in damage from flooding when compared with the 
impacts of premining peak flows.
    (6) Ensure that the fill will not preclude any existing or 
reasonably foreseeable use of surface water or groundwater or, for 
surface water downstream of the fill, preclude attainment of any 
designated use under section 101(a) or 303(c) of the Clean Water Act.
    (7) Ensure that the fill will not cause or contribute to an 
exceedance of any applicable water quality standards.
    (b) Stability requirements--(1) Static safety factor. You must 
design and construct the fill to attain a minimum long-term static 
safety factor of 1.5. The foundation and abutments of the fill must be 
stable under all conditions of construction.
    (2) Special requirement for steep-slope conditions. Where the slope 
in the disposal area exceeds 2.8h:1v (36 percent), or any lesser slope 
designated by the regulatory authority based on local conditions, you 
must construct bench cuts (excavations into stable bedrock) or rock-toe 
buttresses to ensure fill stability.
    (c) Compliance with permit. You must construct the fill in 
accordance with the design and plans approved in the permit in 
accordance with Sec.  780.35 of this chapter.
    (d) Requirements for handling of organic matter and soil materials. 
You must remove all vegetation, other organic matter, and soil 
materials from the disposal area prior to placement of the excess 
spoil. You must store, redistribute, or otherwise use those materials 
in accordance with Sec.  816.22 of this part. You may use soil 
substitutes and supplements if approved in the permit in accordance 
with Sec.  780.12(e) of this chapter.
    (e) Surface runoff control requirements. (1) You must direct 
surface runoff from areas above the fill and runoff from the surface of 
the fill into stabilized channels designed to--
    (i) Meet the requirements of Sec.  816.43 of this part; and
    (ii) Safely pass the runoff from the 100-year, 6-hour precipitation 
event. You must use the appropriate regional Natural Resources 
Conservation Service synthetic storm distribution to determine the peak 
flow from surface runoff from this event.
    (2) You must grade the top surface of a completed fill such that 
the final slope after settlement will be toward properly designed 
drainage channels. You may not direct uncontrolled surface runoff over 
the outslope of the fill.
    (f) Control of water within the footprint of the fill--(1) General 
requirements. If the disposal area contains springs, natural or manmade 
water courses, or wet weather seeps, you must design and construct 
underdrains and temporary diversions as necessary to control erosion, 
prevent water infiltration into the fill, and ensure stability.
    (2) Temporary diversions. Temporary diversions must comply with the 
requirements of Sec.  816.43 of this part.
    (3) Underdrains. (i) You must construct underdrains that are 
comprised of hard rock that is resistant to weathering.
    (ii) You must design and construct underdrains using current, 
prudent engineering practices and any design criteria established by 
the regulatory authority.
    (iii) In constructing rock underdrains, you may use only hard rock 
that is resistant to weathering, such as well-cemented sandstone and 
massive limestone, and that is not acid-forming or toxic-forming. The 
underdrain must be free of soil and fine-grained, clastic rocks such as 
siltstone, shale, mudstone, and claystone. All rock used to construct 
underdrains must meet the criteria in the following table:

[[Page 44662]]

    (iv) The underdrain system must be designed and constructed to 
carry the maximum anticipated infiltration of water due to 
precipitation, snowmelt, and water from seeps and springs in the 
foundation of the disposal area away from the excess spoil fill.
    (v) To provide a safety factor against future changes in local 
surface-water and groundwater hydrology, perforated pipe may be 
embedded within the rock underdrain to enhance the underdrain capacity 
to carry water in excess of the anticipated maximum infiltration away 
from the excess spoil fill. The pipe must be manufactured of materials 
that are not susceptible to corrosion and must be demonstrated to be 
suitable for the deep burial conditions commonly associated with excess 
spoil fill underdrains.
    (vi) The underdrain system must be protected from material piping, 
clogging, and contamination by an adequate filter system designed and 
constructed using current, prudent engineering practices to ensure the 
long-term functioning of the underdrain system.

materials in a manner that will prevent sustained combustion and 
minimize adverse effects on plant growth and the approved postmining 
land use.
    (h) Final configuration. (1) The final configuration of the fill 
must be suitable for the approved postmining land use, compatible with 
the natural drainage pattern and the surrounding terrain, and, to the 
extent practicable, consistent with natural landforms.
    (2) You may construct terraces on the outslope of the fill if 
required for stability, to control erosion, to conserve soil moisture, 
or to facilitate the approved postmining land use. The grade of the 
outslope between terrace benches may not be steeper than 2h: 1v (50 
percent).
    (3)(i) You must configure the top surface of the fill to create a 
topography that includes ridgelines and valleys with varied hillslope 
configurations when practicable, compatible with stability and 
postmining land use considerations, and generally consistent with the 
premining topography.
    (ii) The final surface elevation of the fill may exceed the 
elevation of the surrounding terrain when necessary to minimize 
placement of excess spoil in perennial and intermittent streams, 
provided the final configuration complies with the requirements of 
paragraphs (a)(3) and (h)(1) of this section.
    (iii) The geomorphic reclamation requirements of paragraph 
(h)(3)(i) of this section do not apply in situations in which they 
would result in burial of a greater length of perennial or intermittent 
streams than traditional fill design and construction techniques.
    (i) Impoundments and depressions. No permanent impoundments are 
allowed on the completed fill. You may construct small depressions if 
they--
    (1) Are needed to retain moisture, minimize erosion, create or 
enhance wildlife habitat, or assist revegetation;
    (2) Are not incompatible with the stability of the fill;
    (3) Are consistent with the hydrologic reclamation plan approved in 
the permit in accordance with Sec.  780.22 of this chapter;
    (4) Will not result in elevated levels of parameters of concern in 
discharges from the fill; and
    (5) Are approved by the regulatory authority.
    (j) Surface area stabilization. You must provide slope protection 
to minimize surface erosion at the site. You must revegetate all 
disturbed areas, including diversion channels that are not riprapped or 
otherwise protected, upon completion of construction.
    (k) Inspections and examinations. A qualified registered 
professional engineer, or other qualified professional specialist under 
the direction of the professional engineer, must inspect the fill 
during construction. The professional engineer or specialist must be 
experienced in the construction of earth and rock fills.
    (1) Complete inspections that include the entire fill must be made 
at least quarterly throughout construction, with additional complete 
inspections conducted during critical construction periods. Critical 
construction periods include, at a minimum--

The log must include a description of the specific work locations, 
excess spoil placement methods, compaction adequacy, lift thickness, 
suitability of fill material, special handling of acid-forming and 
toxic-forming materials, deviations from the approved permit, and 
remedial measures taken.
    (3) The qualified registered professional engineer must provide a 
certified report to the regulatory authority promptly after each 
complete inspection conducted under paragraph (k)(1) of this section. 
The report must--
    (i) Certify that the fill has been constructed and maintained as 
designed and in accordance with the approved plan and this chapter.
    (ii) Identify and discuss any evidence of instability, structural 
weakness, or other hazardous conditions. If one of more of those 
conditions exists, you must submit an application for a permit revision 
that includes appropriate remedial design specifications.

the underdrain system is constructed in phases, each phase must be 
certified separately.
    (ii) The photographs accompanying each certified report must be 
taken in adequate size and number with enough terrain or other physical 
features of the site shown to provide a relative scale to the 
photographs and to specifically and clearly identify the site.
    (5) You must retain a copy of each complete inspection report at or 
near the mine site.
    (l) Coal mine waste. You may dispose of coal mine waste in excess 
spoil fills only if approved by the regulatory authority and only if--
    (1) You demonstrate, and the regulatory authority finds in writing, 
that there is no credible evidence that

[[Page 44663]]

mine waste, you must remove at least 90 percent of the water stored 
during the design precipitation event within the 10-day period 
following the design precipitation event.


Sec.  816.87  What special performance standards apply to burning and 
burned coal mine waste?

    (a) Coal mine waste fires must be extinguished by the person who 
conducts the surface mining activities, in accordance with a plan 
approved by the regulatory authority and the Mine Safety and Health 
Administration. The plan must contain, at a minimum, provisions to 
ensure that only those persons authorized by the operator, and who have 
an understanding of the procedures to be used, are involved in the 
extinguishing operations.
    (b) No burning or burned coal mine waste may be removed from a 
permitted disposal area without a removal plan approved by the 
regulatory authority. Consideration must be given to potential hazards 
to persons working or living in the vicinity of the structure.

or soil substitute materials have been redistributed. This requirement 
applies only to rills and gullies that either--
    (i) Disrupt the approved postmining land use or reestablishment of 
the vegetative cover; or
    (ii) Cause or contribute to a violation of water quality standards 
for receiving waters.
    (2) You must reapply soil materials to the filled or regraded rills 
and gullies when necessary to reestablish a vegetative cover. You must 
then replant those areas.


Sec.  816.97  How must I protect and enhance fish, wildlife, and 
related environmental values?

    (a) General requirements. You, the permittee, must, to the extent 
possible using the best technology currently available, minimize 
disturbances and adverse impacts on fish, wildlife, and related

chapter requiring that you revise the permit.
    (iv) You must comply with any species-specific protection measures 
required by the regulatory authority in coordination with the U.S. Fish 
and Wildlife Service.
    (v) Nothing in this chapter authorizes the taking of a threatened 
or endangered species in violation of the Endangered Species Act of 
1973, 16 U.S.C. 1531 et seq.
    (2) State-listed species. (i) You must promptly report to the 
regulatory authority any state-listed threatened or endangered species 
within the permit are or the adjacent area of which you become aware. 
This requirement applies regardless of whether the species was listed 
before or after permit issuance.
    (ii)(A) Upon receipt of a notification under paragraph (b)(2)(i) of 
this section, the regulatory authority will contact and coordinate with 
the appropriate state fish and wildlife agencies.
    (B) The regulatory authority, in coordination with the appropriate 
state fish and wildlife agencies, will identify whether, and under what 
conditions, you may proceed. When necessary, the regulatory authority 
will issue an order under Sec.  774.10(b) of this chapter requiring 
that you revise the permit.
    (c) Bald and golden eagles. (1) You may not conduct any surface 
mining activity in a manner that would result in the unlawful taking of 
a bald or golden eagle, its nest, or any of its eggs.
    (2) You must promptly report to the regulatory authority any golden

golden eagle, its nest, or any of its eggs in violation of the

[[Page 44666]]

Bald and Golden Eagle Protection Act, 16 U.S.C. 668-668d.
    (d) Miscellaneous protective measures for other species of fish and 
wildlife. To the extent possible, using the best technology currently 
available, you must--
    (1) Ensure that electric power transmission lines and other 
transmission facilities used for, or incidental to, surface mining 
activities on the permit area are designed and constructed to minimize 
electrocution hazards to raptors and other avian species with large 
wingspans.
    (2) Locate, construct, operate, and maintain haul and access roads 
and sedimentation control structures in a manner that avoids or 
minimizes impacts on important fish and wildlife species or other 
species protected by state or federal law.
    (3) Design fences, overland conveyors, and other potential barriers 
to permit passage for large mammals, except where the regulatory 
authority determines that such requirements are unnecessary.
    (4) Fence, cover, or use other appropriate methods to exclude 
wildlife from ponds that contain hazardous concentrations of toxic or 
toxic-forming materials.
    (5) Reclaim and reforest lands that were forested at the time of 
application and lands that would revert to forest under conditions of 
natural succession in a manner that enhances recovery of the native 
forest ecosystem as expeditiously as practicable.
    (e) Wetlands and habitat of unusually high value for fish and 
wildlife. To the extent possible, you must avoid disturbances to, 
restore or replace, and, where practicable, enhance, wetlands, riparian 
vegetation along rivers and streams, lentic vegetation bordering ponds 
and lakes, and habitat of unusually high value for fish and wildlife.
    (f) Vegetation requirements for fish and wildlife habitat 
postmining land use. Where fish and wildlife habitat is a postmining 
land use, you must select and arrange the plant species to be used for 
revegetation to maximize the benefits to fish and wildlife. Plant 
species must be native to the area and must be selected on the basis of 
the following criteria:
    (1) Their proven nutritional value for fish or wildlife.
    (2) Their value as cover for fish or wildlife.
    (3) Their ability to support and enhance fish or wildlife habitat 
after the release of performance bonds.
    (4) Their ability to sustain natural succession by allowing the 
establishment and spread of plant species across ecological gradients. 
You may not use invasive plant species that are known to inhibit 
natural succession.
    (g) Vegetation requirements for cropland postmining land use. Where 
cropland is the postmining land use, and where appropriate for 
wildlife-management and crop-management practices, you must intersperse 
the crop fields with trees, hedges, or fence rows to break up large 
blocks of monoculture and to diversify habitat types for birds and 
other animals.
    (h) Vegetation requirements for forestry postmining land uses. 
Where forestry, whether managed or unmanaged, is the postmining land 
use, you must plant native tree and understory species to the extent 
that doing so is not inconsistent with the type of forestry to be 
practiced as part of the postmining land use. In all cases, regardless 
of the type of forestry to be practiced as part of the postmining land 
use, you must intersperse plantings of commercial species with 
plantings of native trees and shrubs of high value to wildlife.
    (i) Vegetation requirements for other postmining land uses. Where 
residential, public service, commercial, industrial, or intensive 
recreational uses are the postmining land use, you must establish--
    (1) Greenbelts comprised of non-invasive native plants that provide 
food or cover for wildlife, unless greenbelts would be inconsistent 
with the approved postmining land use plan for that site.
    (2)(i) A vegetated buffer at least 100 feet wide along each bank of 
all perennial and intermittent streams within the permit area. The 
width of the buffer must be measured horizontally on a line 
perpendicular to the stream beginning at the bankfull elevation or, if 
there are no discernible banks, the centerline of the active channel. 
The buffer must be planted with species native to the area, including 
species adapted to and suitable for planting in riparian zones within 
the buffer. The species planted must consist of native tree and 
understory species if the land was forested at the time of application 
or if it would revert to forest under conditions of natural succession.
    (ii) Paragraph (i)(2)(i) of this section does not apply to 
situations in which a riparian buffer would be incompatible with an 
approved postmining land use that is implemented during the 
revegetation responsibility period before final bond release under 
Sec.  800.42(d) of this chapter.
    (j) Planting arrangement requirements. You must design and arrange 
plantings in a manner that optimizes benefits to wildlife to the extent 
practicable and consistent with the postmining land use.


Sec.  816.99  What measures must I take to prevent and remediate 
landslides?

    (a) You, the permittee or operator, must provide an undisturbed 
natural barrier beginning at the elevation of the lowest coal seam to 
be mined and extending from the outslope for the distance that the 
regulatory authority determines is needed to assure stability. The 
barrier must be retained in place to prevent slides.
    (b)(1) You must notify the regulatory authority by the fastest 
available means whenever a landslide occurs that has the potential to 
adversely affect public property, health, safety, or the environment.
    (2) You must comply with any remedial measures that the regulatory 
authority requires in response to the notification provided in 
paragraph (b)(1) of this section.


Sec.  816.100  What are the standards for conducting reclamation 
contemporaneously with mining?

    You must reclaim all land disturbed by surface mining activities as 
contemporaneously as practicable with the mining operations, except 
when the mining operations are conducted in accordance with a variance 
for concurrent surface and underground mining activities under Sec.  
785.18 of this chapter. Reclamation activities include, but are not 
limited to, backfilling, grading, soil replacement, revegetation, and 
stream restoration.

chapter.
    (ix) The placement, in accordance with Sec.  780.35(b)(3) of this 
chapter, of what would otherwise be excess spoil on the mined-out area 
to heights in excess of the premining elevation when necessary to avoid 
or minimize construction of excess spoil fills on undisturbed land.
    (2) Minimize the creation of uniform slopes and cut-and-fill 
terraces. The regulatory authority may approve cut-and-fill terraces 
only if--
    (i) They are compatible with the approved postmining land use and 
are needed to conserve soil moisture, ensure stability, or control 
erosion on final-graded slopes; or
    (ii) Specialized grading, foundation conditions, or roads are 
required for the approved postmining land use, in which case the final 
grading may include a terrace of adequate width to ensure the safety, 
stability, and erosion control necessary to implement the postmining 
land use.
    (3) Eliminate all highwalls, spoil piles, impoundments, and 
depressions, except in the following situations:
    (i) You may construct or retain small depressions if--
    (A) They are needed to retain moisture, minimize erosion, create or 
enhance wildlife habitat, or assist revegetation;
    (B) They are consistent with the hydrologic reclamation plan 
approved in the permit in accordance with Sec.  780.22 of this chapter; 
and
    (C) You demonstrate that they will not result in elevated levels of 
parameters of concern in discharges from the backfilled and graded 
area.
    (ii) The regulatory authority may approve the retention of 
permanent impoundments if--
    (A) They meet the requirements of Sec. Sec.  816.49 and 816.56 of 
this part;
    (B) They are suitable for the approved postmining land use;
    (C) You can demonstrate compliance with the future maintenance 
provisions of Sec.  800.42(c)(5) of this chapter; and
    (D) You have obtained all necessary approvals and authorizations 
under section 404 of the Clean Water Act when the impoundment is 
located in waters of the United States.
    (iii) You may retain highwalls on previously mined areas to the 
extent provided in Sec.  816.106(b) of this part.
    (iv) You may retain modified highwall segments to the extent 
necessary to replace similar natural landforms removed by the mining 
operation. The regulatory program must establish the conditions under 
which these highwall segments may be retained and the modifications 
that must be made to the highwall to ensure that the retained segment 
resembles similar premining landforms and restores the ecological 
niches that the premining landforms provided. Nothing in this paragraph 
authorizes the retention of modified highwall segments in excess of the 
number, length, and height needed to replace similar premining 
landforms.
    (4) Achieve a postmining slope that does not exceed either the 
angle of repose or such lesser slope as is necessary to achieve a 
minimum long-term static safety factor of 1.3 and to prevent slides.
    (5) Minimize erosion and water pollution, including discharges of 
parameters of concern for which no numerical effluent limitations or 
water quality standards have been established, both on and off the 
site.
    (6) Support the approved postmining land use.
    (b) You must return all spoil to the mined-out area. This 
requirement does not apply to--
    (1) Excess spoil disposed of in accordance with Sec.  816.71 or 
Sec.  816.74 of this part.
    (2) Mountaintop removal mining operations approved under Sec.  
785.14 of this chapter.
    (3) Spoil placed outside the mined-out area in non-steep slope 
areas to restore the approximate original contour by blending the spoil 
into the surrounding terrain, provided that you comply with the 
following requirements:
    (i) You must remove all vegetation and other organic matter from 
the area outside the mined-out area before spoil placement begins. You 
may not burn or bury these materials; you must store, redistribute, or 
use them in the manner specified in Sec.  816.22(f) of this part.
    (ii) You must remove, segregate, store, and redistribute topsoil on 
the area outside the mined-out area in accordance with Sec.  816.22 of 
this part.
    (c) You must compact spoil and waste materials when necessary to 
ensure stability or to prevent the formation of acid or toxic mine 
drainage, but, to the extent possible, you must avoid compacting spoil, 
soil, and other materials placed in what will be the root zone of the 
species planted under the revegetation plan approved in the permit in 
accordance with Sec.  780.12(g) of this chapter.
    (d)(1) You must cover all exposed coal seams with material that is 
noncombustible, nonacid-forming, and nontoxic-forming.
    (2) You must handle and dispose of all other combustible materials 
exposed, used, or produced during mining in accordance with Sec.  
816.89 of this part in a manner that will prevent sustained combustion, 
as approved in the permit in accordance with Sec.  780.12(j) of this 
chapter.
    (3) You must handle all other acid-forming and toxic-forming 
materials--
    (i) In compliance with the plan approved in the permit in 
accordance with Sec.  780.12(d)(4) of this chapter;
    (ii) In compliance with Sec.  816.38 of this part;
    (iii) In compliance with the hydrologic reclamation plan approved 
in the permit in accordance with Sec.  780.22(a) of this chapter; and
    (iv) In a manner that will minimize adverse effects on plant growth 
and the approved postmining land use.
    (e) You must dispose of any coal mine waste placed in the mined-out 
area in accordance with Sec. Sec.  816.81 and 816.83 of this part, 
except that a long-term static safety factor of 1.3 will apply instead 
of the 1.5 factor specified in Sec.  816.81(d)(2) of this part.
    (f) You must prepare final-graded surfaces in a manner that 
minimizes erosion and provides a surface for replacement of soil 
materials that will minimize slippage.


Sec.  816.104  What special provisions for backfilling, grading, and 
surface configuration apply to sites with thin overburden?

    (a) Applicability. This section applies only where the thickness of 
all overburden strata multiplied by the swell factor for those strata 
plus the thickness of any waste materials to be returned to the mined-
out area is less than the combined thickness of the overburden and coal 
seam or seams prior to removing the coal to the extent that there is 
insufficient material to restore the approximate original contour. 
Specifically, there is insufficient material to achieve a surface 
configuration that--
    (1) Closely resembles the surface configuration of the mined area 
prior to any mining; and
    (2) Blends into and complements the drainage pattern of the 
surrounding terrain.
    (b) Performance standards. Where thin overburden as described in 
paragraph (a) of this section occurs

[[Page 44668]]

within the permit area, you must backfill all mined areas and grade all 
disturbed areas in accordance with the plan approved in the permit 
under Sec.  780.12(d) of this chapter. At a minimum, you must--
    (1) Use all spoil and waste materials available from the entire 
permit area to attain the lowest practicable grade that does not exceed 
the angle of repose.
    (2) Comply with the requirements of paragraphs (a)(2) through (f) 
of Sec.  816.102 of this part.
    (3) Ensure that the final surface configuration blends into and 
complements the drainage pattern of the surrounding terrain to the 
extent possible.


Sec.  816.105  What special provisions for backfilling, grading, and 
surface configuration apply to sites with thick overburden?

    (a) Applicability. This section applies only where the thickness of 
all overburden strata multiplied by the swell factor for those strata 
plus the thickness of any waste materials to be returned to the mined-
out area exceeds the combined thickness of the overburden strata and 
the coal seam or seams in place to the extent that there is more 
material than can be used to restore the approximate original contour. 
Specifically, the amount of material to be returned to the mined-out 
area is so large that it is not possible to achieve a surface 
configuration that closely resembles the surface configuration of the 
mined land prior to any mining.
    (b) Performance standards. Where thick overburden as described in 
paragraph (a) of this section occurs within the permit area, you must 
backfill all mined areas and grade all disturbed areas in accordance 
with the plan approved in the permit under Sec.  780.12(d) of this 
chapter. At a minimum, you must--
    (1) Backfill the mined-out area to the approximate original contour 
and then place the remaining spoil and waste materials on top of the 
backfilled area to the extent possible, as determined in accordance 
with the excess spoil minimization requirements of Sec.  780.35(b) of 
this chapter.
    (2) Grade the backfilled area to the lowest practicable grade that 
is ecologically sound, consistent with the postmining land use, and 
compatible with the surrounding region. No slope may exceed the angle 
of repose.
    (3) Comply with the requirements of paragraphs (a)(2) through (f) 
of Sec.  816.102 of this part.
    (4) Dispose of any excess spoil in accordance with Sec.  816.71 or 
Sec.  816.74 of this part.
    (5) Ensure that the final surface configuration blends into and 
complements the drainage pattern of the surrounding terrain to the 
extent possible.


Sec.  816.106  What special provisions for backfilling, grading, and 
surface configuration apply to previously mined areas with a 
preexisting highwall?

    (a) Remining operations on previously mined areas that contain a 
preexisting highwall must comply with the requirements of Sec. Sec.  
816.102 through 816.107 of this part, except as provided in this 
section.
    (b) The highwall elimination requirements of Sec.  816.102(a) of 
this part do not apply to remining operations for which you demonstrate 
in writing, to the regulatory authority's satisfaction, that the volume 
of all reasonably available spoil is insufficient to completely 
backfill the reaffected or enlarged highwall. Instead, for those 
operations, you must eliminate the highwall to the maximum extent 
technically practical in accordance with the following criteria:
    (1) You must use all spoil generated by the remining operation and 
any other reasonably available spoil to backfill the area. You must 
include reasonably available spoil in the immediate vicinity of the 
remining operation within the permit area.
    (2) You must grade the backfilled area to a slope that is 
compatible with the approved postmining land use and that provides 
adequate drainage and long-term stability.
    (3) Any highwall remnant must be stable and not pose a hazard to 
the public health and safety or to the environment. You must 
demonstrate, to the satisfaction of the regulatory authority, that the 
highwall remnant is stable.
    (4) You must not disturb spoil placed on the outslope during 
previous mining operations if disturbance would cause instability of 
the remaining spoil or otherwise increase the hazard to the public 
health and safety or to the environment.


Sec.  816.107  What special provisions for backfilling, grading, and 
surface configuration apply to operations on steep slopes?

    (a) Surface mining activities on steep slopes must comply with this 
section and the requirements of Sec. Sec.  816.102 through 816.106 of 
this part, except where--
    (1) Mining is conducted on flat or gently rolling terrain with an 
occasional steep slope through which the mining proceeds and leaves a 
plain or predominantly flat area; or
    (2) Operations are conducted in accordance with part 824 of this 
chapter.
    (b) You may not place the following materials on the downslope:
    (1) Spoil.
    (2) Waste materials of any type.
    (3) Debris, including debris from clearing and grubbing, except for 
woody materials used to enhance fish and wildlife habitat.
    (4) Abandoned or disabled equipment.
    (c) You may not disturb land above the highwall unless the 
regulatory authority finds that disturbance will facilitate compliance 
with the environmental protection standards of this subchapter and the 
disturbance is limited to that necessary to facilitate compliance.
    (d) You must handle woody materials in accordance with Sec.  
816.22(f) of this part. You may not bury them in the backfill.


Sec.  816.111  How must I revegetate areas disturbed by mining 
activities?

    (a) You, the permittee, must establish a diverse, effective, 
permanent vegetative cover on regraded areas and on all other disturbed 
areas except--
    (1) Water areas approved as a postmining land use or in support of 
the postmining land use.
    (2) The surfaces of roads approved for retention to support the 
postmining land use.
    (3) Rock piles, water areas, and other non-vegetative features 
created to restore or enhance wildlife habitat under the fish and 
wildlife protection and enhancement plan approved in the permit in 
accordance with Sec.  780.16 of this chapter.
    (4) Any other impervious surface, such as a building or a parking 
lot, approved as part of or in support of the postmining land use. This 
provision applies only to structures and facilities constructed before 
expiration of the revegetation responsibility period.
    (b) The reestablished vegetative cover must--
    (1) Comply with the revegetation plan approved in the permit in 
accordance with Sec.  780.12(g) of this chapter.
    (2) Be consistent with the approved postmining land use and the 
plant communities described in Sec.  779.19 of this chapter.
    (3) Be at least equal in extent of cover to the natural vegetation 
of the area.
    (4) Be capable of stabilizing the soil surface and, in the long 
term, preventing erosion in excess of what would have occurred 
naturally had the site not been disturbed.
    (5) Not inhibit the establishment of trees and shrubs when the 
revegetation

[[Page 44669]]

plan approved in the permit requires the use of woody plants.
    (c) Volunteer plants of species that are desirable components of 
the plant communities described in the permit application under Sec.  
779.19 of this chapter and that are not inconsistent with the 
postmining land use may be considered in determining whether the 
requirements of Sec. Sec.  816.111 and 816.116 have been met.
    (d) You must stabilize all areas upon which you have redistributed 
soil or soil substitute materials. You must use one or a combination of 
the following methods, unless the regulatory authority determines that 
neither method is necessary to stabilize the surface and control 
erosion--
    (1) Establishing a temporary vegetative cover consisting of 
noncompetitive and non-invasive species, either native or domesticated 
or a combination thereof.
    (2) Applying a suitable mulch free of weed and noxious plant seeds. 
You must use native hay mulch to the extent that it is commercially 
available.
    (e) You must plant all disturbed areas with the species needed to 
establish a permanent vegetative cover during the first normal period 
for favorable planting conditions after distribution of the topsoil or 
other plant-growth medium. The normal period for favorable planting 
conditions is the generally accepted local planting time for the type 
of plant materials approved in the permit as part of the revegetation 
plan under Sec.  780.12(g) of this chapter.


Sec.  816.113  [Reserved]


Sec.  816.114  [Reserved]


Sec.  816.115  How long am I responsible for revegetation after 
planting?

    (a) General provisions. (1) The period of extended responsibility 
for successful revegetation will begin after the last year of augmented 
seeding, fertilizing, irrigation, or other work, excluding husbandry 
practices that are approved by the regulatory authority in accordance 
with paragraph (d) of this section.
    (2) The initial planting of small areas that are regraded and 
planted as a result of the removal of sediment control structures and 
associated structures and facilities such as diversion ditches, 
disposal and storage areas for accumulated sediment, sediment pond 
embankments, and ancillary roads used to access those structures need 
not be considered an augmented seeding necessitating an extended or 
separate revegetation responsibility period.
    (b) Areas of more than 26.0 inches of average annual precipitation. 
In areas of more than 26.0 inches of annual average precipitation, the 
period of responsibility will continue for a period of not less than--
    (1) Five full years, except as provided in paragraph (b)(2) of this 
section.
    (i) The vegetation parameters for grazing land, pasture land, or 
cropland must equal or exceed the approved success standard during the 
growing season of any 2 years of the responsibility period, except the 
first year.
    (ii) On all other areas, the parameters must equal or exceed the 
applicable success standard during the growing season of the last year 
of the responsibility period.
    (2) Two full years for lands eligible for remining included in a 
permit approved under Sec.  785.25 of this chapter. The lands must 
equal or exceed the applicable ground cover standard during the growing 
season of the last year of the responsibility period.
    (c) Areas of 26.0 inches or less average annual precipitation. In 
areas of 26.0 inches or less average annual precipitation, the period 
of responsibility will continue for a period of not less than:
    (1) Ten full years, except as provided in paragraph (c)(2) of this 
section.
    (i) The vegetation parameters for grazing land, pasture land, or 
cropland must equal or exceed the approved success standard during the 
growing season of any two years after year six of the responsibility 
period.
    (ii) On all other areas, the parameters must equal or exceed the 
applicable success standard during the growing season of the last year 
of the responsibility period.
    (2) Five full years for lands eligible for remining included in a 
permit approved under Sec.  785.25 of this chapter. The lands must 
equal or exceed the applicable ground cover standard during the growing 
seasons of the last two consecutive years of the responsibility period.
    (d) Normal husbandry practices. (1) The regulatory authority may 
approve selective husbandry practices, excluding augmented seeding, 
fertilization, or irrigation, provided it obtains prior approval from 
OSMRE in accordance with Sec.  732.17 of this chapter that the 
practices are normal husbandry practices, without extending the period 
of responsibility for revegetation success and bond liability, if those 
practices can be expected to continue as part of the postmining land 
use or if discontinuance of the practices after the liability period 
expires will not reduce the probability of permanent revegetation 
success.
    (2) Approved practices must be normal husbandry practices within 
the region for unmined lands having land uses similar to the approved 
postmining land use of the disturbed area, including such practices as 
disease, pest, and vermin control; and any pruning, reseeding, and 
transplanting specifically necessitated by such actions.


Sec.  816.116  What are the standards for determining revegetation 
success?

    (a) The regulatory authority must select standards for revegetation 
success and statistically valid sampling techniques for measuring 
revegetation success. The standards and techniques must be made 
available to the public in written form.
    (b) The standards for success applied to a specific permit must be 
adequate to demonstrate restoration of premining land use capability 
and must reflect the revegetation plan requirements of Sec.  780.12(g) 
of this chapter. They must be based upon the following data--
    (1) The plant community and vegetation information required under 
Sec.  779.19 of this chapter.
    (2) The soil type and productivity information required under Sec.  
779.21 of this chapter.
    (3) The land use capability and productivity information required 
under Sec.  779.22 of this chapter.
    (4) The postmining land use approved under Sec.  780.24 of this 
chapter, but only to the extent that the approved postmining land use 
actually will be implemented before expiration of the revegetation 
responsibility period. Otherwise, the site must be revegetated in a 
manner that will restore native plant communities and the revegetation 
success standards for the site must reflect that requirement.
    (c) Except for the areas identified in Sec.  816.111(a) of this 
part, standards for success must include--
    (1) Species diversity.
    (2) Areal distribution of species.
    (3) Ground cover, except for land actually used for cropland after 
the completion of regrading and redistribution of soil materials.
    (4) Production, for land used for cropland, pasture, or grazing 
land either before permit issuance or after the completion of regrading 
and redistribution of soil materials.
    (5) Stocking, for areas revegetated with woody plants.
    (d) The ground cover, production, or stocking of the revegetated 
area will be considered equal to the approved success standard for 
those parameters when the measured values are not less than 90 percent 
of the success standard, using a 90-percent statistical confidence

[[Page 44670]]

interval (i.e., a one-sided test with a 0.10 alpha error).
    (e) For all areas revegetated with woody plants, regardless of the 
postmining land use, the regulatory authority must specify minimum 
stocking and planting arrangements on the basis of local and regional 
conditions and after coordination with and approval by the state 
agencies responsible for the administration of forestry and wildlife 
programs. Coordination and approval may occur on either a program-wide 
basis or a permit-specific basis.
    (f)(1) Only those species of trees and shrubs approved in the 
permit as part of the revegetation plan under Sec.  780.12(g) of this 
chapter or volunteer trees and shrubs of species that meet the 
requirements of Sec.  816.111(c) of this part may be counted in 
determining whether stocking standards have been met.
    (2)(i) At the time of final bond release under Sec.  800.42(d) of 
this chapter, at least 80 percent of the trees and shrubs used to 
determine success must have been in place for 60 percent of the 
applicable minimum period of responsibility under Sec.  816.115 of this 
part.
    (ii) Trees and shrubs counted in determining revegetation success 
must be healthy and have been in place for not less than two growing 
seasons. Any replanting must be done by means of transplants to allow 
for proper accounting of plant stocking.
    (iii)(A) For purposes of paragraph (f)(2)(ii) of this section, 
volunteer trees and shrubs of species that meet the requirements of 
Sec.  816.111(c) of this part may be deemed equivalent to planted 
specimens two years of age or older.
    (B) Suckers on shrubby vegetation can be counted as volunteer 
plants when it is evident that the shrub community is vigorous and 
expanding.
    (iv) The requirements of paragraphs (f)(2)(i) and (ii) of this 
section will be deemed met when records of woody vegetation planted 
show that--
    (A) No woody plants were planted during the last two growing 
seasons of the responsibility period; and
    (B) If any replanting of woody plants took place earlier during the 
responsibility period, the total number planted during the last 60 
percent of that period is less than 20 percent of the total number of 
woody plants required to meet the stocking standard.
    (3) Vegetative ground cover on areas planted with trees or shrubs 
must be of a nature that allows for natural establishment and 
succession of native plants, including trees and shrubs.
    (g) Special provision for areas that are to be developed within the 
revegetation responsibility period. Portions of the permit area that 
are to be developed for industrial, commercial, or residential use 
within the revegetation responsibility period need not meet production 
or stocking standards. For those areas, the vegetative ground cover 
must not be less than that required to control erosion.
    (h) Special provision for previously mined areas. Previously mined 
areas need only meet a vegetative ground cover standard, unless the 
regulatory authority specifies otherwise. At a minimum, the cover on 
the revegetated previously mined area must not be less than the ground 
cover existing before redisturbance and must be adequate to control 
erosion.
    (i) Special provision for prime farmland. For prime farmland, the 
revegetation success standard provisions of Sec.  823.15 of this 
chapter apply in lieu of the requirements of paragraphs (b) through (h) 
of this section.


Sec.  816.131  What actions must I take when I temporarily cease mining 
operations?

    (a)(1) Each person who temporarily ceases to conduct surface mining 
activities at a particular site must effectively secure surface 
facilities in areas in which there are no current operations, but where 
operations are to be resumed under an approved permit.
    (2) Temporary cessation does not relieve a person of his or her 
obligation to comply with any provisions of the approved permit.
    (b)(1) You must submit a notice of intent to temporarily cease 
operations to the regulatory authority before ceasing mining and 
reclamation operations for 30 or more days, or as soon as you know that 
a temporary cessation will extend beyond 30 days.
    (2) The notice of temporary cessation must include a statement of 
the--
    (i) Exact number of surface acres disturbed within the permit area 
prior to temporary cessation;
    (ii) Extent and kind of reclamation accomplished before temporary 
cessation; and
    (iii) Backfilling, regrading, revegetation, environmental 
monitoring, and water treatment activities that will continue during 
temporary cessation.


Sec.  816.132  What actions must I take when I permanently cease mining 
operations?

    (a) Persons who permanently cease surface mining activities at a 
particular site must close, backfill, or otherwise permanently reclaim 
all disturbed areas in accordance with this chapter and the permit 
approved by the regulatory authority.
    (b) All equipment, structures, underground openings, or other 
facilities must be removed and the affected land reclaimed, unless the 
regulatory authority approves retention of those features because they 
are suitable for the postmining land use or environmental monitoring.


Sec.  816.133  What provisions concerning postmining land use apply to 
my operation?

    Except as provided in Sec.  780.24(c) of this chapter, you, the 
permittee, must restore all disturbed areas in a timely manner to 
conditions that are capable of supporting--
    (a) The uses they were capable of supporting before any mining, as

performance standards of this part and any additional criteria 
specified by the regulatory authority.
    (2) A road damaged by a catastrophic event, such as a flood or 
earthquake, must be repaired as soon as is practicable after the damage 
has occurred.
    (f) Reclamation. A road not to be retained as part of an approved 
postmining land use must be reclaimed in accordance with the approved 
reclamation plan as soon as practicable after it is no longer needed 
for mining and reclamation operations. Reclamation must include--
    (1) Closing the road to traffic.
    (2) Removing all bridges and culverts unless approved as part of 
the postmining land use.
    (3) Removing or otherwise disposing of road-surfacing materials 
that are incompatible with the postmining land use and revegetation

revegetating disturbed surfaces in accordance with Sec. Sec.  816.111, 
816.115, and 816.116 of this chapter.


Sec.  816.151  What additional standards apply to primary roads?

    (a) Primary roads must meet the requirements of Sec.  816.150 of 
this part and the additional requirements of this section.
    (b) Certification. The construction or reconstruction of primary 
roads must be certified in a report to the regulatory authority by a 
qualified registered professional engineer, or in any state that 
authorizes land surveyors to certify the construction or reconstruction 
of primary roads, a qualified registered professional land surveyor 
with experience in the design and construction of roads. The report 
must indicate that the primary road has been constructed or 
reconstructed as designed and in accordance with the approved plan.
    (c) Safety factor. Each primary road embankment must have a minimum 
static factor of 1.3 or meet the requirements established under Sec.  
780.37(c) of this chapter.
    (d) Location. (1) To minimize erosion, a primary road must be 
located, insofar as is practicable, on the most stable available 
surface.
    (2) Fords of perennial or intermittent streams are prohibited 
unless they are specifically approved by the regulatory authority as 
temporary routes during periods of road construction.
    (e) Drainage control. In accordance with the approved plan--
    (1) Each primary road must be constructed, or reconstructed, and 
maintained to have adequate drainage control, using structures such as, 
but not limited to, bridges, ditches, cross drains, and ditch relief 
drains. The drainage control system must be designed to safely pass the 
peak runoff from the 10-year, 6-hour precipitation event, or any 
greater event specified by the regulatory authority.
    (2) Drainage pipes and culverts must be installed as designed, and 
maintained in a free and operating condition and to prevent or control 
erosion at inlets and outlets.
    (3) Drainage ditches must be constructed and maintained to prevent 
uncontrolled drainage over the road surface and embankment.
    (4) Culverts must be installed and maintained to sustain the 
vertical soil pressure, the passive resistance of the foundation, and

Sec.  817.15  [Reserved]


Sec.  817.22  How must I handle topsoil, subsoil, and other plant 
growth media?

    (a) Removal and salvage. (1) You, the permittee, must separately 
remove and salvage all topsoil and other soil materials identified for 
salvage and use as postmining plant growth media in the soil handling 
plan approved in the permit under Sec.  784.12(e) of this chapter. You 
must complete removal and salvage of these materials from the area to 
be disturbed before any drilling, blasting, mining, or other surface 
disturbance takes place on that area.
    (2) The regulatory authority may choose not to require the removal 
of topsoil and other soil materials for minor disturbances that--
    (i) Occur at the site of small structures, such as power poles, 
signs, or fence lines; or
    (ii) Will not destroy the existing vegetation and will not cause 
erosion.
    (b) Storage. (1) You must segregate and, except as provided in 
paragraph (b)(3) of this section, stockpile the materials removed under 
paragraph (a) of this section when it is impractical to redistribute 
those materials promptly on regraded areas.
    (2) Stockpiled materials must--
    (i) Be selectively placed on a stable site within the permit area;
    (ii) Be protected from contaminants and unnecessary compaction that 
would interfere with revegetation;
    (iii) Be protected from wind and water erosion through prompt 
establishment and maintenance of an effective, quick-growing, non-
invasive vegetative cover or through other measures approved by the 
regulatory authority; and
    (iv) Not be moved until required for redistribution unless approved 
by the regulatory authority.
    (3) When stockpiling of organic matter and soil materials removed 
under paragraphs (a) and (f) of this section would be detrimental to 
the quality or quantity of those materials, you may temporarily 
redistribute those soil materials on an approved site within the permit 
area to enhance the current use of that site until the materials are 
needed for later reclamation, provided that--
    (i) Temporary redistribution will not permanently diminish the 
capability of the topsoil of the host site; and
    (ii) The redistributed material will be preserved in a condition 
more suitable for redistribution than if it were stockpiled.
    (c) Soil substitutes and supplements. When the soil handling plan 
approved in the permit in accordance with Sec.  784.12(e) of this 
chapter provides for the use of substitutes for or supplements to the 
existing topsoil or subsoil, you must salvage, store, and redistribute 
the overburden materials selected and approved for that purpose in a 
manner consistent with paragraphs (a), (b), and (e) of this section.
    (d) Site preparation. (1) You must minimize grading of backfilled 
areas to avoid compaction of the reconstructed root zone, as specified 
in the soil handling plan approved in the permit in accordance with 
Sec.  784.12(e) of this chapter. Compaction is allowed only to the 
extent necessary to ensure stability and to comply with water quality 
standards.
    (2) If necessary, you must rip, chisel-plow, or otherwise 
mechanically treat backfilled and graded areas before topsoil 
redistribution to reduce potential slippage of the redistributed 
material and to promote root penetration. You may conduct this 
treatment after soil redistribution if doing so will not harm the 
redistributed material.
    (e) Redistribution. (1) You must redistribute the materials 
removed, salvaged, and, if necessary, stored under paragraphs (a) 
through (c) of this section in a manner that--
    (i) Complies with the soil handling plan developed under Sec.  
784.12(e) of this chapter and approved as part of the permit.
    (ii) Is consistent with the approved postmining land use, contours, 
and surface-water drainage systems.

[[Page 44674]]

    (iii) Minimizes compaction of the materials to the extent possible 
and alleviates any excess compaction that may occur.
    (iv) Protects the materials from wind and water erosion before and 
after seeding and planting to the extent necessary to ensure 
establishment of a successful vegetative cover and to avoid causing or 
contributing to a violation of applicable water quality standards.
    (v) Achieves an approximately uniform, stable thickness across the 
regraded area, except that the thickness may vary when consistent with 
the postmining land use and when variations are necessary or desirable 
to achieve specific revegetation goals and ecological diversity, as set 
forth in the revegetation plan developed under Sec.  784.12(g) of this 
chapter and approved as part of the permit.
    (2) You must use a statistically valid sampling technique to 
document that soil materials have been redistributed in the locations 
and depths required by the soil handling plan developed under Sec.  
784.12(e) of this chapter and approved as part of the permit.
    (3) The regulatory authority may choose not to require the 
redistribution of topsoil on the embankments of permanent impoundments 
or on the embankments of roads to be retained as part of the postmining 
land use if it determines that--
    (i) Placement of topsoil on those embankments is inconsistent with 
the requirement to use the best technology currently available to 
prevent sedimentation, and
    (ii) The embankments will be otherwise stabilized.
    (f) Organic matter. (1) You must salvage duff, other organic 
litter, and vegetative materials such as tree tops, small logs, and 
root balls. You may not burn organic matter or bury it in the backfill.
    (2) Except as otherwise provided in paragraph (f)(3) of this 
section, you must redistribute the materials salvaged under paragraph 
(f)(1) of this section across the regraded surface or incorporate them 
into the soil to control erosion, promote growth of vegetation, serve 
as a source of native plant seeds and soil inoculants to speed 
restoration of the soil's ecological community, and increase the 
moisture retention capability of the soil.
    (3) Vegetative debris must be redistributed in accordance with 
paragraph (f)(2) of this section, used for stream restoration purposes, 
or used to construct fish and wildlife habitat enhancement features.


Sec.  817.34  How must I protect the hydrologic balance?

    (a) You, the permittee, must conduct all underground mining and 
reclamation activities to--

Sec.  784.22 of this chapter and approved in the permit.
    (8) Protect groundwater quality by using the best technology 
currently available to handle earth materials and runoff in a manner 
that avoids the formation of acid or toxic mine drainage and by 
managing excavations and other disturbances to prevent or control 
groundwater degradation.
    (9) Protect groundwater quantity by handling earth materials and 
runoff in a manner that will restore the approximate premining recharge 
capacity of the reclaimed area as a whole, excluding coal mine waste 
disposal areas and excess spoil fills, so as to allow the movement of 
water into the groundwater system.
    (10) Protect surface-water quality by using the best technology 
currently available to handle earth materials, groundwater discharges, 
and runoff in a manner that--
    (i) Avoids the formation of acid or toxic mine drainage.
    (ii) Prevents additional contribution of suspended solids to 
streamflow or runoff outside the permit area to the extent possible.
    (iii) Otherwise prevents water pollution.
    (11) Protect surface-water quality and flow rates by handling earth 
materials and runoff in accordance with the steps outlined in the 
hydrologic reclamation plan and the surface-water runoff control plan 
approved in the permit in accordance with Sec. Sec.  784.22 and 780.29 
of this chapter, respectively.
    (b)(1) To the maximum extent practicable, you must use mining and 
reclamation practices that minimize water pollution, changes in flow, 
and adverse impacts on stream biota rather than relying upon water 
treatment to minimize those impacts.
    (2) You must install, use, and maintain any necessary water-
treatment facilities or water-quality controls if drainage control, 
materials handling, stabilization and revegetation of disturbed areas, 
diversion of runoff, mulching, and other reclamation and remedial 
practices are not adequate to meet the requirements of this section and 
Sec.  817.42 of this part.
    (c) The regulatory authority may require that you take preventive, 
remedial, or monitoring measures in addition to those set forth in this 
part to prevent material damage to the hydrologic balance outside the 
permit area.
    (d)(1) You must examine the hydraulic structures identified under 
Sec.  784.29 of this chapter after each occurrence of the following 
precipitation events:
    (i) In areas with an average annual precipitation of more than 26.0 
inches, an event of a size equal to or greater than that of a storm 
with a 2-year recurrence interval. You must use the appropriate 
regional Natural Resources Conservation Service synthetic storm 
distribution to determine peak flow for a storm with that recurrence 
interval.
    (ii) In areas with an average annual precipitation of 26.0 inches 
or less, a significant event of a size specified by the regulatory 
authority.
    (2) You must prepare a report, which must be certified by a 
registered professional engineer, and submit the report to the 
regulatory authority within 48 hours of cessation of the applicable 
precipitation event under paragraph (d)(1) of this section. The report 
must address the performance of the hydraulic structures, identify and 
describe any material damage to the hydrologic balance outside the 
permit area that occurred, and identify and describe the remedial 
measures taken in response to that damage.

    (2) Monitoring must continue through mining and during reclamation 
until final release of bond under Sec.  800.42(d) of this chapter. As 
provided in Sec.  800.42(a) of this chapter, the regulatory authority 
may not release any portion of the bond if an evaluation of monitoring 
data indicates that adverse trends exist that could result in material 
damage to the hydrologic balance outside the permit area.
    (b)(1) You must submit biological condition monitoring data to the 
regulatory authority on an annual basis, or more frequently if 
prescribed by the regulatory authority.
    (2) Monitoring reports must include analytical results from each 
sample taken during the reporting period.
    (c) You must promptly notify the regulatory authority and take the 
actions required under Sec.  773.17(e) of this chapter whenever the 
analysis of any sample indicates noncompliance with the terms and 
conditions of the permit.
    (d) Whenever information available to the regulatory authority 
indicates that additional monitoring is necessary to meet the 
requirements of the regulatory

[[Page 44676]]

program, the regulatory authority must issue an order under Sec.  
774.10(b) of this chapter requiring that you revise your permit to 
include the necessary additional monitoring.


Sec.  817.38  How must I handle acid-forming and toxic-forming 
materials?

    You, the permittee, must use the best technology currently 
available to handle acid-forming and toxic-forming materials and 
underground development waste in a manner that will avoid the creation 
of acid or toxic mine drainage into surface water and groundwater. At a 
minimum, you must--
    (a) Identify potential acid-forming and toxic-forming materials in 
overburden strata and the stratum immediately below the lowest coal 
seam to be mined and cover exposed coal seams and the stratum 
immediately beneath the lowest coal seam mined with a layer of 
compacted material with a hydraulic conductivity at least two orders of 
magnitude lower than the hydraulic conductivity of the adjacent less-
compacted spoil to minimize contact and interaction with water.
    (b) Identify the anticipated postmining groundwater level for all 
locations at which you propose to place acid-forming or toxic-forming 
materials.
    (c) Selectively handle and place acid-forming and toxic-forming 
materials within the backfill in accordance with the plan approved in 
the permit under Sec.  784.12(d)(4) of this chapter, unless the permit 
allows placement of those materials in an excess spoil fill or a coal 
mine waste refuse pile. When placing those materials in the backfill, 
you must use one or more of the following techniques, as appropriate 
and as approved in the permit:
    (1) Completely surround acid-forming and toxic-forming materials 
with compacted material with a hydraulic conductivity at least two 
orders of magnitude lower than the hydraulic conductivity of adjacent 
less-compacted spoil.
    (2) Place acid-forming and toxic-forming materials in a location 
below the water table where they will remain fully saturated at all 
times, provided that the permittee demonstrates, and the regulatory 
authority finds in writing in the permit, that complete saturation will 
prevent the formation of acid or toxic leachate.
    (3) Treat or otherwise neutralize acid-forming and toxic-forming 
materials to prevent the formation of acid or toxic mine drainage. This 
technique also may be used in combination with either isolation under 
paragraph (c)(1) of this section or saturation under paragraph (c)(2) 
of this section.
    (d) When approved in the permit, place acid-forming and toxic-
forming materials in an excess spoil fill or a coal mine waste refuse 
pile, using one or both of the following techniques, as appropriate:
    (1) Completely surround acid-forming and toxic-forming materials 
with compacted material with a hydraulic conductivity at least two 
orders of magnitude lower than the hydraulic conductivity of the 
adjacent less-compacted spoil or coal mine waste.
    (2) Treat or otherwise neutralize acid-forming and toxic-forming 
materials to prevent the formation of acid or toxic mine drainage.
    (e) Temporarily store acid-forming and toxic-forming materials only 
if the regulatory authority specifically approves temporary storage as 
necessary and finds in writing in the permit that the proposed storage 
method will protect surface water and groundwater by preventing 
erosion, the formation of polluted runoff, and the infiltration of 
polluted water into aquifers. The regulatory authority must specify a 
maximum time for temporary storage, which may not exceed the period 
until burial first becomes feasible. In addition, storage must not 
result in any risk of water pollution, adverse impacts to the 
biological condition of perennial or intermittent streams, or other 
environmental damage.
    (f) Adhere to disposal, treatment, and storage practices that are 
consistent with other material handling and disposal provisions of this 
chapter.


Sec.  817.39  What must I do with exploratory or monitoring wells when 
I no longer need them?

    (a) Except as provided in paragraph (b) of this section, you, the 
permittee, must permanently seal exploratory or monitoring wells in a 
safe and environmentally sound manner in accordance with Sec.  817.13 
of this part before the regulatory authority may approve full release 
of the bond posted for the land on which the wells are located under 
section Sec.  800.42(d) of this chapter.
    (b) With the prior approval of the regulatory authority, you may 
transfer wells to another party for further use. The conditions of the 
transfer must comply with state and local laws. You will remain 
responsible for the proper management of the wells until full release 
of the bond posted for the land on which the wells are located under 
Sec.  800.42(d) of this chapter.


Sec.  817.40  What responsibility do I have to replace water supplies?

    (a) Replacement of adversely-impacted water supplies. (1) You, the 
permittee, must promptly replace any drinking, domestic or residential 
water supply that is contaminated, diminished or interrupted as a 
result of underground mining activities that you conducted after 
October 24, 1992, if the affected well or spring was in existence 
before the date the regulatory authority received the permit 
application for the activities causing the loss, contamination or 
interruption.
    (2) The replacement supply must be equivalent to the quantity and 
quality of the premining supply.
    (3) Replacement includes provision of an equivalent water supply 
delivery system and payment of operation and maintenance expenses in 
excess of customary and reasonable delivery costs for the premining 
water supply. If you and the water supply owner agree, the obligation 
to pay operation and maintenance costs may be satisfied by a one-time 
payment in an amount that covers the present worth of the increased 
annual operation and maintenance costs for a period upon which you and 
the water supply owner agree.
    (4) If the affected water supply was not needed for the land use in 
existence at the time of loss, contamination, or diminution, you may 
satisfy the replacement requirements by demonstrating that a suitable 
alternative water source is available and could feasibly be developed, 
provided you obtain written concurrence from the owner of the affected 
water supply.
    (b) Measures to address anticipated adverse impacts to protected 
water supplies. For anticipated loss of or damage to a protected water 
supply, you must adhere to the requirements set forth in the permit in 
accordance with Sec.  784.22(b) of this chapter.
    (c) Measures to address unanticipated adverse impacts to protected 
water supplies. For unanticipated loss of or damage to a protected 
water supply, you must--
    (1) Provide an emergency temporary water supply within 24 hours of 
notification of the loss. The temporary supply must be adequate in 
quantity and quality to meet normal household needs.
    (2) Develop and submit a plan for a permanent replacement supply to 
the regulatory authority within 30 days of receiving notice that an 
unanticipated loss of or damage to a protected water supply has 
occurred.
    (3) Provide a permanent replacement water supply within 2 years of 
the date

[[Page 44677]]

of receiving notice of an unanticipated loss of or damage to a 
protected water supply.
    (d) Basis for determination of adverse impact. The regulatory 
authority must use the baseline hydrologic and geologic information 
required under Sec.  784.19 of this chapter and all other available 
information to determine whether and to what extent the mining 
operation adversely impacted the damaged water supply.


Sec.  817.41  Under what conditions may I discharge water and other 
materials into an underground mine?

    (a) You may not discharge any water or other materials from your 
operation into an underground mine unless the regulatory authority 
specifically approves the discharge in writing, based upon a 
demonstration that--
    (1) The discharge will be made in a manner that--
    (i) Minimizes disturbances to the hydrologic balance within the 
permit area;
    (ii) Prevents material damage to the hydrologic balance outside the 
permit area, including the hydrologic balance of the area in which the 
underground mine receiving the discharge is located;
    (iii) Does not adversely impact the biological condition of 
perennial or intermittent streams; and
    (iv) Otherwise eliminates public hazards resulting from surface 
mining activities.
    (2) The discharge will not result in a violation of applicable 
water quality standards or effluent limitations.
    (3)(i) The discharge will be at a known rate and of a quality that 
will meet the effluent limitations for pH and total suspended solids 
referenced in Sec.  817.42 of this part.
    (ii) The regulatory authority may approve discharges of water that 
exceed the effluent limitations for pH and total suspended solids if 
the available evidence indicates that there is no direct hydrologic 
connection between the underground mine and other waters and that those 
exceedances will not be inconsistent with paragraph (a)(1) of this 
section.
    (4) The Mine Safety and Health Administration has approved the 
discharge.
    (5) You have obtained written permission from the owner of the mine 
into which the discharge is to be made and you have provided a copy of 
that authorization to the regulatory authority.

registered professional land surveyor as specified in paragraph 
(a)(11)(iv) of this section, must promptly provide to the regulatory 
authority a certified report that the impoundment has been constructed 
and/or maintained as designed and in accordance with the approved plan 
and this chapter. The report must include a discussion of any 
appearance of instability, any structural weakness or other hazardous 
condition, the depth and elevation of any impounded waters, the 
existing storage capacity, any existing or required monitoring 
procedures and instrumentation, and any other aspects of the structure 
affecting stability.
    (iii) You must retain a copy of the report at or near the minesite.
    (iv) In any state that authorizes land surveyors to prepare and 
certify plans in accordance with Sec.  784.25(a) of this chapter, a 
qualified registered professional land surveyor may inspect any 
temporary or permanent impoundment that does not meet the criteria for 
High Hazard Class or Significant Hazard Class dams in TR-60, or that 
does not meet the criteria of Sec.  77.216(a) of this title, and 
certify and submit the report required by paragraph (a)(11)(ii) of this 
section, except that a qualified registered professional engineer must 
certify all coal mine waste impounding structures covered by Sec.  
817.84 of this chapter. The professional land surveyor must be 
experienced in the construction of impoundments.
    (12) Examinations. Impoundments that meet the criteria for High 
Hazard Class or Significant Hazard Class dams in TR-60, or that meet 
the criteria of Sec.  77.216 of this title, must be examined in 
accordance with Sec.  77.216-3 of this title. Impoundments that do not 
meet the criteria for High Hazard Class or Significant Hazard Class 
dams in TR-60, or that are not subject to Sec.  77.216 of this title, 
must be examined at least quarterly. A qualified person designated by 
the operator must examine impoundments for the appearance of structural 
weakness and other hazardous conditions.
    (13) Emergency procedures. If any examination or inspection 
discloses that a potential hazard exists, the person who examined the 
impoundment must promptly inform the regulatory authority of the 
finding and of the emergency procedures formulated for public 
protection and remedial action. The regulatory authority must be 
notified immediately if adequate procedures cannot be formulated or 
implemented. The regulatory authority then must notify the appropriate 
agencies that other emergency procedures are required to protect the 
public.
    (b) Requirements that apply only to permanent impoundments. A 
permanent impoundment of water may be created if authorized by the 
regulatory authority in the approved permit based upon the following 
demonstration:
    (1) The size and configuration of the impoundment will be adequate 
for its intended purposes.
    (2) The quality of impounded water will be suitable on a permanent 
basis for its intended use and, after reclamation, will meet applicable 
state and federal water quality standards. Discharges from the 
impoundment will meet applicable effluent limitations and will not 
degrade the quality of receiving water below applicable state and 
federal water quality standards.
    (3) The water level will be sufficiently stable and be capable of 
supporting the intended use.
    (4) Final grading will provide for adequate safety and access for 
proposed water users.
    (5) The impoundment will not result in the diminution of the 
quality and quantity of water used by surrounding landowners for 
agricultural, industrial, recreational, or domestic uses.
    (6) The impoundment will be suitable for the approved postmining 
land use.
    (7) Approval of the impoundment will not result in retention of 
spoil piles or ridges that are inconsistent with the definition of 
approximate original contour.
    (8) Approval of the impoundment will not result in the creation of 
an excess spoil fill elsewhere within the permit area.
    (9) The impoundment has been designed with dimensions and other 
characteristics that will enhance fish and wildlife habitat to the 
extent that doing so is not inconsistent with the intended use.
    (c) Requirements that apply only to temporary impoundments that 
rely primarily upon storage. (1) In lieu of meeting the requirements in 
paragraph (a)(9)(i) of this section, the regulatory authority may 
approve an impoundment that relies primarily on storage to control the 
runoff from the design precipitation event when you demonstrate, and a 
qualified registered professional engineer or qualified registered 
professional land surveyor in accordance with Sec.  784.25(a) of this 
chapter certifies, that the impoundment will safely control the design 
precipitation event.
    (2) You must use current prudent engineering practices to safely 
remove the water from an impoundment constructed in accordance with 
paragraph (c)(1) of this section.
    (3) An impoundment constructed in accordance with paragraph (c)(1) 
of this section must be located where failure would not be expected to 
cause loss of life or serious property damage, unless the impoundment 
meets one of the following exceptions:
    (i) An impoundment that meets the criteria for High Hazard Class or 
Significant Hazard Class dams in TR-60, or that meets the criteria of 
Sec.  77.216(a) of this title, and is designed to control the 
precipitation of the probable maximum precipitation of a 6-hour event, 
or any greater event specified by the regulatory authority.
    (ii) An impoundment not included in paragraph (c)(3)(i) of this 
section that is designed to control the precipitation of the 100-year, 
6-hour event, or any greater event specified by the regulatory 
authority.


Sec.  817.56  How must I rehabilitate sedimentation ponds, diversions, 
impoundments, and treatment facilities after I no longer need them?

    Before abandoning a permit area or seeking bond release, you must 
ensure that all temporary structures are removed and reclaimed, and 
that all permanent sedimentation ponds, diversions, impoundments, and 
treatment facilities meet the requirements of this chapter for 
permanent structures, have been

[[Page 44681]]

maintained properly, and meet the requirements of the approved 
reclamation plan for permanent structures and impoundments. You must 
renovate these structures if necessary to meet the requirements of this 
chapter and to conform to the approved reclamation plan.


Sec.  817.57  What additional performance standards apply to surface 
activities conducted in, through, or adjacent to a perennial or 
intermittent stream?

    (a)(1) General prohibition. (i) You, the permittee or operator, may 
not conduct underground mining activities in or through a perennial or 
intermittent stream, or that would disturb the surface of land within 
100 feet of a perennial or intermittent stream, unless the regulatory 
authority authorizes you to do so in the permit after making the 
findings required under Sec.  784.28 of this chapter. The 100-foot 
distance must be measured horizontally on a line perpendicular to the 
stream beginning at the bankfull elevation or, if there are no 
discernible banks, the centerline of the active channel.
    (ii) The prohibition in paragraph (a)(1)(i) of this section applies 
only to activities conducted on the land surface. It does not apply to 
underground mining activities conducted beneath the land surface, 
including activities conducted beneath a perennial or intermittent 
stream.
    (2) Clean Water Act requirements. You may conduct underground 
mining activities in waters of the United States only if you first 
obtain all necessary authorizations, certifications, and permits under 
the Clean Water Act, 33 U.S.C. 1251 et seq.
    (b) Requirements for mining through or diverting perennial or 
intermittent streams--(1) Compliance with permit. If your permit 
authorizes you to mine through or divert a perennial or intermittent 
stream, you must comply with the designs and construction and 
maintenance plans approved in the permit.
    (2) Restoration of form and function. You must restore the form and 
ecological function of the stream segment as expeditiously as 
practicable. You must do so either as part of the construction of a 
permanent stream-channel diversion or as part of the construction of a 
restored stream channel when the area in which the stream was located 
before mining is no longer needed for surface mining activities.
    (i) Form. A restored stream channel or a stream-channel diversion 
need not exactly replicate the channel morphology that existed before 
mining, but, except as provided in paragraph (b)(4) of this section, it 
must have a channel morphology comparable to the premining form of the 
affected stream segment in terms of baseline stream pattern, profile, 
and dimensions, including channel slope, sinuosity, water depth, 
bankfull depth, bankfull width, width of the flood-prone area, and 
dominant in-stream substrate.
    (ii) Function. (A) A stream flowing through a restored stream 
channel or a stream-channel diversion must meet the functional 
restoration criteria established by the regulatory authority under 
Sec.  784.28(e)(1) of this chapter.
    (B) The restored stream need not have precisely the same biological 
condition or biota as the stream segment did before mining, but the 
biological condition of the restored stream must be adequate to support 
the uses of that stream segment that existed before mining and it must 
not preclude attainment of the premining designated uses of that stream 
segment under section 101(a) or 303(c) of the Clean Water Act before 
mining.
    (C) The biological condition of the restored stream must be 
determined using a protocol that meets the requirements of Sec.  
784.19(e)(2) of this chapter.
    (D) Populations of organisms used to determine the biological 
condition must be self-sustaining within the restored stream segment.
    (iii) Bond and bond release requirements. (A) The performance bond 
calculations for the operation must include a specific line item for 
restoration of the ecological function of the stream segment, as 
provided in Sec.  800.14(b)(2) of this chapter.
    (B) You must post a surety bond, a collateral bond, or a 
combination of surety and collateral bonds to cover the cost of 
restoration of the ecological function of the stream segment.
    (C) You must demonstrate full restoration of the physical form of 
the stream segment before you can qualify for Phase I bond release 
under Sec.  800.42(b)(1) of this chapter.
    (D) You must demonstrate full restoration of the ecological 
function of the stream segment before you can qualify for final bond 
release under Sec.  800.42(d) of this chapter.
    (3) Certification. Upon completion of construction of a stream-
channel diversion or a restored stream channel, you must obtain a 
certification from a qualified registered professional engineer that 
the stream-channel diversion or restored stream channel has been 
constructed in accordance with the design approved in the permit and 
meets all requirements of this section other than the functional 
restoration requirements of paragraph (b)(2)(ii) of this section.
    (4) Special provision for restoration of degraded stream segments. 
If the stream segment to be mined through or diverted is in a degraded 
condition before mining, you must implement measures to enhance the 
form and ecological function of the segment as part of the restoration 
or diversion process.
    (c) Prohibition on placement of sedimentation control structures in 
streams. (1) Except as provided in paragraph (c)(2) of this section, 
you may not construct a sedimentation pond in a perennial or 
intermittent stream or use perennial or intermittent streams as waste 
treatment systems to convey surface runoff from the disturbed area to a 
sedimentation pond.
    (2) The prohibition in paragraph (c)(1) of this section does not 
apply to excess spoil fills or coal mine waste disposal facilities in 
steep-slope areas when use of a perennial or intermittent stream 
segment as a waste treatment system for sediment control or 
construction of a sedimentation pond in a perennial or intermittent 
stream would have less overall adverse impact on fish, wildlife, and 
related environmental values than construction of diversions and 
sedimentation ponds on slopes above the stream.
    (3) When the circumstances described in paragraph (c)(2) of this 
situation exist, the following requirements apply:
    (i) You must minimize the length of the stream segment used as a 
waste treatment system to the extent possible and, when practicable, 
maintain an undisturbed buffer along that segment in accordance with 
paragraph (a)(1) of this section.
    (ii) You must place the sedimentation pond as close to the toe of 
the excess spoil fill or coal mine waste disposal structure as 
possible.
    (iii) Following the completion of construction and revegetation of 
the fill or coal mine waste disposal structure, you must remove the 
sedimentation pond and restore the stream segment in accordance with 
paragraph (b)(2) of this section.


Sec.  817.59  How must I maximize coal recovery?

    You must conduct underground mining activities so as to maximize 
the utilization and conservation of the coal, while using the best 
appropriate technology currently available to maintain environmental 
integrity, so that reaffecting the land in the future through surface 
coal mining operations is minimized.

[[Page 44682]]

[[Page 44684]]

[GRAPHIC] [TIFF OMITTED] TP27JY15.004


    \1\ Ground vibration must be measured as the particle velocity. 
Particle velocity must be recorded in three mutually perpendicular 
directions. The maximum allowable peak particle velocity applies to 
each of the three measurements.
    \2\ Applicable to the scaled-distance equation of paragraph 
(d)(3)(i) of this section.
    (ii) You must provide a seismographic record for each blast.

    (3) Scaled-distance equation. (i) You may use the scaled-distance 
equation, W = (D/Ds)2, to determine the allowable charge weight of 
explosives to be detonated in any 8-millisecond period, without seismic 
monitoring, where W = the maximum weight of explosives, in pounds; D = 
the distance, in feet, from the blasting site to the nearest protected 
structure; and Ds = the scaled-distance factor. The regulatory 
authority may initially approve the scaled-distance equation using the 
values for the scaled-distance factor listed in paragraph (d)(2)(i) of 
this section.
    (ii) The regulatory authority may authorize development of a 
modified scaled-distance factor upon receipt of a written request by 
the operator, supported by seismographic records of blasting at the 
minesite. The modified scale-distance factor must be determined such 
that the particle velocity of the predicted ground vibration will not 
exceed the prescribed maximum allowable peak particle velocity of 
paragraph (d)(2)(i) of this section at a 95-percent confidence level.
    (4) Blasting-level chart. (i) You may use the ground-vibration 
limits in Figure 1 to determine the maximum allowable ground vibration.

[[Page 44685]]

[GRAPHIC] [TIFF OMITTED] TP27JY15.005

    (ii) If the Figure 1 limits are used, you must provide a 
seismographic record including both particle velocity and vibration-
frequency levels for each blast. The regulatory authority must approve 
the method for the analysis of the predominant frequency contained in 
the blasting records before application of this alternative blasting 
criterion.
    (5) The regulatory authority must reduce the maximum allowable 
ground vibration beyond the limits otherwise provided by this section, 
if determined necessary to provide damage protection.
    (6) The regulatory authority may require that you conduct seismic 
monitoring of any or all blasts or may specify the location at which 
the measurements are taken and the degree of detail necessary in the 
measurement.
    (e) The maximum airblast and ground-vibration standards of 
paragraphs (b) and (d) of this section do not apply at the following 
locations:
    (1) At structures owned by the permittee and not leased to another 
person.
    (2) At structures owned by the permittee and leased to another 
person, if a written waiver by the lessee is submitted to the 
regulatory authority before blasting.

Sec.  817.71  How must I dispose of excess spoil?

    (a) General requirements. You, the permittee or operator, must 
mechanically transport and place excess spoil in designated disposal 
areas, including approved valley fills and other types of approved 
fills, within the permit area in a controlled manner in compliance with 
the requirements of this section. In general, you must place excess 
spoil in a manner that will--
    (1) Minimize the adverse effects of leachate and surface water 
runoff from the fill on surface water, groundwater, and the biological 
condition of perennial and intermittent streams within the permit and 
adjacent areas.
    (2) Ensure mass stability and prevent mass movement during and 
after construction.
    (3) Ensure that the final surface configuration of the fill is 
suitable for revegetation and the approved postmining land use or uses 
and is compatible with the natural drainage pattern and surroundings.
    (4) Minimize disturbances to, and adverse impacts on, fish, 
wildlife, and related environmental values to the extent possible, 
using the best technology currently available.
    (5) Ensure that the fill will not change the size or frequency of 
peak flows from precipitation events or thaws in a way that would 
result in an increase in damage from flooding when compared with the 
impacts of premining peak flows.
    (6) Ensure that the fill will not preclude any existing or 
reasonably foreseeable use of surface water or groundwater or, for 
surface water downstream of the fill, preclude attainment of any 
designated use under section 101(a) or 303(c) of the Clean Water Act.
    (7) Ensure that the fill will not cause or contribute to an 
exceedance of any applicable water quality standards.
    (b) Stability requirements. (1) Static safety factor. You must 
design and construct the fill to attain a minimum long-term static 
safety factor of 1.5. The foundation and abutments of the fill must be 
stable under all conditions of construction.
    (2) Special requirement for steep-slope conditions. Where the slope 
in the disposal area exceeds 2.8h:1v (36 percent), or any lesser slope 
designated by the regulatory authority based on local conditions, you 
must construct bench cuts (excavations into stable bedrock) or rock-toe 
buttresses to ensure fill stability.

possible using the best technology currently available, minimize 
disturbances and adverse impacts on fish, wildlife, and related 
environmental values and achieve enhancement of those resources where 
practicable, as described in detail in the fish and wildlife protection 
and enhancement plan approved in the permit in accordance with Sec.  
784.16 of this chapter.
    (b) Species listed or proposed for listing as threatened or 
endangered. (1) Federally-listed species. (i) You may not conduct any 
underground mining activity that is likely to jeopardize the continued 
existence of threatened or endangered species listed by the Secretary 
or proposed for listing by the Secretary or that is likely to result in 
the destruction or adverse modification of designated critical habitat 
in violation of the Endangered Species Act of 1973, 16 U.S.C. 1531 et 
seq.
    (ii) You must promptly report to the regulatory authority any 
federally-listed threatened or endangered species within the permit 
area or the adjacent area of which you become aware. This requirement 
applies regardless of whether the species was listed before or after 
permit issuance.
    (iii)(A) Upon receipt of a notification under paragraph (b)(2)(ii) 
of this section, the regulatory authority will contact and coordinate 
with the appropriate state and federal fish and wildlife agencies.
    (B) The regulatory authority, in coordination with the appropriate 
state and federal fish and wildlife agencies, will identify whether, 
and under what conditions, you may proceed. When necessary, the 
regulatory authority will issue an order under Sec.  774.10(b) of this 
chapter requiring that you revise the permit.
    (iv) You must comply with any species-specific protection measures 
required by the regulatory authority in coordination with the U.S. Fish 
and Wildlife Service.
    (v) Nothing in this chapter authorizes the taking of a threatened 
or endangered species in violation of the Endangered Species Act of 
1973, 16 U.S.C. 1531 et seq.
    (2) State-listed species. (i) You must promptly report to the 
regulatory authority any state-listed threatened or endangered species 
within the permit area or the adjacent area of which you become aware. 
This requirement applies regardless of whether the species was listed 
before or after permit issuance.
    (ii)(A) Upon receipt of a notification under paragraph (b)(2)(i) of 
this section, the regulatory authority will contact and coordinate with 
the appropriate state fish and wildlife agencies.
    (B) The regulatory authority, in coordination with the appropriate 
state fish and wildlife agencies, will identify whether, and under what 
conditions, you may proceed. When necessary, the regulatory authority 
will issue an order under Sec.  774.10(b) of this chapter requiring 
that you revise the permit.
    (c) Bald and golden eagles. (1) You may not conduct any underground 
mining activity in a manner that would result in the unlawful taking of 
a bald or golden eagle, its nest, or any of its eggs.
    (2) You must promptly report to the regulatory authority any golden 
or bald eagle nest within the permit area of which you become aware.
    (3) Upon notification, the regulatory authority will contact and 
coordinate with the U.S. Fish and Wildlife Service and, when 
appropriate, the state fish and wildlife agency to identify whether, 
and under what conditions, you may proceed.
    (4) Nothing in this chapter authorizes the taking of a bald or 
golden eagle, its nest, or any of its eggs in violation of the Bald and 
Golden Eagle Protection Act, 16 U.S.C. 668-668d.
    (d) Miscellaneous protective measures for other species of fish and 
wildlife. To the extent possible, using the best technology currently 
available, you must--
    (1) Ensure that electric power transmission lines and other 
transmission facilities used for, or incidental to, surface mining 
activities on the permit area are designed and constructed to minimize 
electrocution hazards to raptors and other avian species with large 
wingspans.
    (2) Locate, construct, operate, and maintain haul and access roads 
and sedimentation control structures in a manner that avoids or 
minimizes impacts on important fish and wildlife

[[Page 44691]]

species or other species protected by state or federal law.
    (3) Design fences, overland conveyors, and other potential barriers 
to permit passage for large mammals, except where the regulatory 
authority determines that such requirements are unnecessary.
    (4) Fence, cover, or use other appropriate methods to exclude 
wildlife from ponds that contain hazardous concentrations of toxic or 
toxic-forming materials.
    (5) Reclaim and reforest lands that were forested at the time of 
application and lands that would revert to forest under conditions of 
natural succession in a manner that enhances recovery of the native 
forest ecosystem as expeditiously as practicable.
    (e) Wetlands and habitat of unusually high value for fish and 
wildlife. To the extent possible, you must avoid disturbances to, 
restore or replace, and, where practicable, enhance, wetlands, riparian 
vegetation along rivers and streams, lentic vegetation bordering ponds 
and lakes, and habitat of unusually high value for fish and wildlife.
    (f) Vegetation requirements for fish and wildlife habitat 
postmining land use. Where fish and wildlife habitat is a postmining 
land use, you must select and arrange the plant species to be used for 
revegetation to maximize the benefits to fish and wildlife. Plant 
species must be native to the area and must be selected on the basis of 
the following criteria:
    (1) Their proven nutritional value for fish or wildlife.
    (2) Their value as cover for fish or wildlife.
    (3) Their ability to support and enhance fish or wildlife habitat 
after the release of performance bonds.
    (4) Their ability to sustain natural succession by allowing the 
establishment and spread of plant species across ecological gradients. 
You may not use invasive plant species that are known to inhibit 
natural succession.
    (g) Vegetation requirements for cropland postmining land use. Where 
cropland is the postmining land use, and where appropriate for 
wildlife-management and crop-management practices, you must intersperse 
the crop fields with trees, hedges, or fence rows to break up large 
blocks of monoculture and to diversify habitat types for birds and 
other animals.
    (h) Vegetation requirements for forestry postmining land uses. 
Where forestry, whether managed or unmanaged, is the postmining land 
use, you must plant native tree and understory species to the extent 
that doing so is not inconsistent with the type of forestry to be 
practiced as part of the postmining land use. In all cases, regardless 
of the type of forestry to be practiced as part of the postmining land 
use, you must intersperse plantings of commercial species with 
plantings of native trees and shrubs of high value to wildlife.
    (i) Vegetation requirements for other postmining land uses. Where 
residential, public service, commercial, industrial, or intensive 
recreational uses are the postmining land use, you must establish--
    (1) Greenbelts comprised of non-invasive native plants that provide 
food or cover for wildlife, unless greenbelts would be inconsistent 
with the approved postmining land use plan for that site.
    (2)(i) A vegetated buffer at least 100 feet wide along each bank of 
all perennial and intermittent streams within the permit area. The 
width of the buffer must be measured horizontally on a line 
perpendicular to the stream beginning at the bankfull elevation or, if 
there are no discernible banks, the centerline of the active channel. 
The buffer must be planted with species native to the area, including 
species adapted to and suitable for planting in riparian zones within 
the buffer. The species planted must consist of native tree and 
understory species if the land was forested at the time of application 
or if it would revert to forest under conditions of natural succession.
    (ii) Paragraph (i)(2)(i) of this section does not apply to 
situations in which a riparian buffer would be incompatible with an 
approved postmining land use that is implemented during the 
revegetation responsibility period before final bond release under 
Sec.  800.42(d) of this chapter.
    (j) Planting arrangement requirements. You must design and arrange 
plantings in a manner that optimizes benefits to wildlife to the extent 
practicable and consistent with the postmining land use.


Sec.  817.99  What measures must I take to prevent and remediate 
landslides?

    (a) You must notify the regulatory authority by the fastest 
available means whenever a landslide occurs that has the potential to 
adversely affect public property, health, safety, or the environment.
    (b) You must comply with any remedial measures that the regulatory 
authority requires in response to the notification provided in 
paragraph (a) of this section.


Sec.  817.100  What are the standards for conducting reclamation 
contemporaneously with mining?

    (a) You must reclaim all areas disturbed by surface impacts 
incident to an underground coal mine as contemporaneously as 
practicable with the mining operations, except when the mining 
operations are conducted in accordance with a variance for concurrent 
surface and underground mining activities under Sec.  785.18 of this 
chapter. Reclamation activities include, but are not limited to, 
backfilling, grading, soil replacement, revegetation, and stream 
restoration.
    (b) The regulatory authority may establish schedules that define 
contemporaneous reclamation.


Sec.  817.102  How must I backfill surface excavations and grade and 
configure the land surface?

    (a) You, the permittee or operator, must backfill all surface 
excavations and grade all disturbed areas in compliance with the plan 
approved in the permit in accordance with Sec.  784.12(d) of this 
chapter to--
    (1) Restore the approximate original contour as the final surface 
configuration, except in the following situations:
    (i) Sites for which the regulatory authority has approved a 
variance under Sec.  785.16 of this chapter.
    (ii) Remining operations on previously mined areas, but only to the 
extent specified in Sec.  817.106(b) of this part.

(a)(3)(ii) of this section and Sec.  784.35(b)(4) of this chapter.
    (vi) The placement, in accordance with Sec.  784.35(b)(3) of this 
chapter, of what would otherwise be excess spoil on the mined-out area 
to heights in excess of the premining elevation when necessary to avoid 
or minimize construction of excess spoil fills on undisturbed land.
    (vii) Regrading of settled and revegetated spoil storage sites at 
the conclusion of underground mining activities, provided the following 
conditions are met:
    (A) The settled and revegetated storage sites are composed of spoil 
or non-acid-forming or non-toxic-forming underground development waste.
    (B) The spoil or underground development waste is not located so as 
to be detrimental to the environment,

[[Page 44692]]

the health and safety of the public, or the approved postmining land 
use.
    (C) You demonstrate, through standard geotechnical analysis, that 
the spoil or underground development waste has a 1.3 static safety 
factor for material placed on a solid bench and a 1.5 static safety 
factor for material not placed on a solid bench.
    (D) The surface of the spoil or underground development waste is 
revegetated in accordance with Sec. Sec.  817.111 and 817.116 of this 
part.
    (E) Surface runoff is controlled in accordance with Sec.  784.29 of 
this chapter and Sec. Sec.  817.43 and 817.45 of this part.
    (F) The regulatory authority determines that disturbance of the 
existing spoil or underground development waste would increase 
environmental harm or adversely affect the health or safety of the 
public.
    (G) The spoil is not needed to eliminate the highwall or to meet 
other regulatory program requirements.
    (2) Minimize the creation of uniform slopes and cut-and-fill 
terraces. The regulatory authority may approve cut-and-fill terraces 
only if--
    (i) They are compatible with the approved postmining land use and 
are needed to conserve soil moisture, ensure stability, or control 
erosion on final-graded slopes; or
    (ii) Specialized grading, foundation conditions, or roads are 
required for the approved postmining land use, in which case the final 
grading may include a terrace of adequate width to ensure the safety, 
stability, and erosion control necessary to implement the postmining 
land use.
    (3) Eliminate all highwalls, spoil piles, impoundments, and 
depressions, except in the following situations:
    (i) You may construct or retain small depressions if--
    (A) They are needed to retain moisture, minimize erosion, create or 
enhance wildlife habitat, or assist revegetation;
    (B) They are consistent with the hydrologic reclamation plan 
approved in the permit in accordance with Sec.  784.22 of this chapter; 
and
    (C) You demonstrate that they will not result in elevated levels of 
parameters of concern in discharges from the backfilled and graded 
area.
    (ii) The regulatory authority may approve the retention of 
permanent impoundments if--
    (A) They meet the requirements of Sec. Sec.  817.49 and 817.56 of 
this part;
    (B) They are suitable for the approved postmining land use; and
    (C) You can demonstrate compliance with the future maintenance 
provisions of Sec.  800.42(c)(5) of this chapter.
    (D) You have obtained all necessary approvals and authorizations 
under section 404 of the Clean Water Act when the impoundment is 
located in waters of the United States.
    (iii) You may retain highwalls on previously mined areas to the 
extent provided in Sec.  817.106(b) of this part.
    (iv) You may retain modified highwall segments to the extent 
necessary to replace similar natural landforms removed by the mining 
operation. The regulatory program must establish the conditions under 
which these highwall segments may be retained and the modifications 
that must be made to the highwall to ensure that the retained segment 
resembles similar premining landforms and restores the ecological 
niches that the premining landforms provided. Nothing in this paragraph 
authorizes the retention of modified highwall segments in excess of the 
number, length, and height needed to replace similar premining 
landforms.
    (v) You may retain settled and revegetated spoil storage sites 
under the conditions specified in paragraph (a)(1)(vii) of this 
section.
    (4) Achieve a postmining slope that does not exceed either the 
angle of repose or such lesser slope as is necessary to achieve a 
minimum long-term static safety factor of 1.3 and to prevent slides.
    (5) Minimize erosion and water pollution, including discharges of 
parameters of concern for which no numerical effluent limitations or 
water quality standards have been established, both on and off the 
site.
    (6) Support the approved postmining land use.
    (b) You must return all spoil to the surface excavations from which 
the spoil was removed. This requirement does not apply to--
    (1) Excess spoil disposed of in accordance with Sec.  817.71 or 
Sec.  817.74 of this part.
    (2) Spoil placed outside surface excavations in non-steep slope 
areas to restore the approximate original contour by blending the spoil 
into the surrounding terrain, provided that you comply with the 
following requirements:
    (i) You must remove all vegetation and other organic matter from 
the area upon which you intend to place spoil for blending purposes. 
You may not burn or bury these materials; you must store, redistribute, 
or use them in the manner specified in Sec.  817.22(f) of this part.
    (ii) You must remove, segregate, store, and redistribute topsoil, 
in accordance with Sec.  817.22 of this part, from the area upon which 
you intend to place spoil for blending purposes.
    (3) Settled and revegetated spoil storage sites under the 
conditions specified in paragraph (a)(1)(vii) of this section.
    (c) You must compact spoil and waste materials when necessary to 
ensure stability or to prevent the formation of acid or toxic mine 
drainage, but, to the extent possible, you must avoid compacting spoil, 
soil, and other materials placed in what will be the root zone of the 
species planted under the revegetation plan approved in the permit in 
accordance with Sec.  784.12(g) of this chapter.
    (d)(1) You must cover all exposed coal seams with material that is 
noncombustible, nonacid-forming, and nontoxic-forming.
    (2) You must handle and dispose of all other combustible materials 
exposed, used, or produced during mining in accordance with Sec.  
817.89 of this part in a manner that will prevent sustained combustion, 
as approved in the permit in accordance with Sec.  784.12(j) of this 
chapter.
    (3) You must handle all other acid-forming and toxic-forming 
materials--
    (i) In compliance with the plan approved in the permit in 
accordance with Sec.  784.12(d)(4) of this chapter;
    (ii) In compliance with Sec.  817.38 of this part;
    (iii) In compliance with the hydrologic reclamation plan approved 
in the permit in accordance with Sec.  784.22(a) of this chapter; and
    (iv) In a manner that will minimize adverse effects on plant growth 
and the approved postmining land use.
    (e) You must dispose of any coal mine waste placed in the surface 
excavation in accordance with Sec. Sec.  817.81 and 817.83 of this 
part, except that a long-term static safety factor of 1.3 will apply 
instead of the 1.5 factor specified in Sec.  817.81(d)(2) of this part.
    (f) You must prepare final-graded surfaces in a manner that 
minimizes erosion and provides a surface for replacement of soil 
materials that will minimize slippage.


Sec.  817.106  What special provisions for backfilling, grading, and 
surface configuration apply to previously mined areas with a 
preexisting highwall?

    (a) Remining operations on previously mined areas that contain a 
preexisting highwall must comply with the requirements of Sec. Sec.  
817.102 through 817.107 of this part, except as provided in this 
section.
    (b) The highwall elimination requirements of Sec.  817.102(a) of 
this part do not apply to remining operations for

[[Page 44693]]

which you demonstrate in writing, to the regulatory authority's 
satisfaction, that the volume of all reasonably available spoil is 
insufficient to completely backfill the reaffected or enlarged 
highwall. Instead, for those operations, you must eliminate the 
highwall to the maximum extent technically practical in accordance with 
the following criteria:
    (1) You must use all spoil generated by the remining operation and 
any other reasonably available spoil to backfill the area. You must 
include reasonably available spoil in the immediate vicinity of the 
remining operation within the permit area.
    (2) You must grade the backfilled area to a slope that is 
compatible with the approved postmining land use and that provides 
adequate drainage and long-term stability.
    (3) Any highwall remnant must be stable and not pose a hazard to 
the public health and safety or to the environment. You must 
demonstrate, to the satisfaction of the regulatory authority, that the 
highwall remnant is stable.
    (4) You must not disturb spoil placed on the outslope during 
previous mining operations if disturbance would cause instability of 
the remaining spoil or otherwise increase the hazard to the public 
health and safety or to the environment.


Sec.  817.107  What special provisions for backfilling, grading, and 
surface configuration apply to operations on steep slopes?

    (a) Underground mining activities on steep slopes must comply with 
this section and the requirements of Sec. Sec.  817.102 through 817.106 
of this part.
    (b) You may not place the following materials on the downslope:
    (1) Spoil.
    (2) Waste materials of any type.
    (3) Debris, including debris from clearing and grubbing, except for 
woody materials used to enhance fish and wildlife habitat.
    (4) Abandoned or disabled equipment.
    (c) You may not disturb land above the highwall unless the 
regulatory authority finds that disturbance will facilitate compliance 
with the environmental protection standards of this subchapter and the 
disturbance is limited to that necessary to facilitate compliance.
    (d) You must handle woody materials in accordance with Sec.  
817.22(f) of this part. You may not bury them in the backfill.


Sec.  817.111  How must I revegetate the area disturbed by mining?

    (a) You, the permittee, must establish a diverse, effective, 
permanent vegetative cover on regraded areas and on all other disturbed 
areas except--
    (1) Water areas approved as a postmining land use or in support of 
the postmining land use.
    (2) The surfaces of roads approved for retention to support the 
postmining land use.
    (3) Rock piles, water areas, and other non-vegetative features 
created to restore or enhance wildlife habitat under the fish and 
wildlife protection and enhancement plan approved in the permit in 
accordance with Sec.  784.16 of this chapter.
    (4) Any other impervious surface, such as a building or a parking 
lot, approved as part of or in support of the postmining land use. This 
provision applies only to structures and facilities constructed before 
expiration of the revegetation responsibility period.
    (b) The reestablished vegetative cover must--
    (1) Comply with the revegetation plan approved in the permit in 
accordance with Sec.  784.12(g) of this chapter.
    (2) Be consistent with the approved postmining land use and the 
plant communities described in Sec.  783.19 of this chapter.
    (3) Be at least equal in extent of cover to the natural vegetation 
of the area.
    (4) Be capable of stabilizing the soil surface and, in the long 
term, preventing erosion in excess of what would have occurred 
naturally had the site not been disturbed.
    (5) Not inhibit the establishment of trees and shrubs when the 
revegetation plan approved in the permit requires the use of woody 
plants.
    (c) Volunteer plants of species that are desirable components of 
the plant communities described in the permit application under Sec.  
783.19 of this chapter and that are not inconsistent with the 
postmining land use may be considered in determining whether the 
requirements of Sec. Sec.  817.111 and 817.116 have been met.
    (d) You must stabilize all areas upon which you have distributed 
soil or soil substitute materials. You must use one or a combination of 
the following methods, unless the regulatory authority determines that 
neither method is necessary to stabilize the surface and control 
erosion--
    (1) Establishing a temporary vegetative cover consisting of 
noncompetitive and non-invasive species, either native or domesticated 
or a combination thereof.
    (2) Applying suitable mulch free of weed and noxious plant seeds. 
You must use native hay mulch to the extent that it is commercially 
available.
    (e) You must plant all disturbed areas with the species needed to 
establish a permanent vegetative cover during the first normal period 
for favorable planting conditions after redistribution of the topsoil 
or other plant-growth medium. The normal period for favorable planting 
conditions is the generally accepted local planting time for the type 
of plant materials approved in the permit as part of the revegetation 
plan under Sec.  784.12(g) of this chapter.


Sec.  817.113  [Reserved]


Sec.  817.114  [Reserved]


Sec.  817.115  How long am I responsible for revegetation after 
planting?

    (a) General provisions. (1) The period of extended responsibility 
for successful revegetation will begin after the last year of augmented 
seeding, fertilizing, irrigation, or other work, excluding husbandry 
practices that are approved by the regulatory authority in accordance 
with paragraph (d) of this section.
    (2) The initial planting of small areas that are regraded and 
planted as a result of the removal of sediment control structures and 
associated structures and facilities such as diversion ditches, 
disposal and storage areas for accumulated sediment and sediment pond 
embankment material, and ancillary roads used to access those 
structures need not be considered an augmented seeding necessitating an 
extended or separate revegetation responsibility period.
    (b) Areas of more than 26.0 inches of average annual precipitation. 
In areas of more than 26.0 inches of annual average precipitation, the 
period of responsibility will continue for a period of not less than--
    (1) Five full years, except as provided in paragraph (b)(2) of this 
section.
    (i) The vegetation parameters for grazing land, pasture land, or 
cropland must equal or exceed the approved success standard during the 
growing season of any 2 years of the responsibility period, except the 
first year.
    (ii) On all other areas, the parameters must equal or exceed the 
applicable success standard during the growing season of the last year 
of the responsibility period.
    (2) Two full years for lands eligible for remining included in a 
permit approved under Sec.  785.25 of this chapter. The lands must 
equal or exceed the applicable ground cover standard

[[Page 44694]]

during the growing season of the last year of the responsibility 
period.
    (c) Areas of 26.0 inches or less average annual precipitation. In 
areas of 26.0 inches or less average annual precipitation, the period 
of responsibility will continue for a period of not less than:
    (1) Ten full years, except as provided in paragraph (c)(2) of this 
section.
    (i) The vegetation parameters for grazing land, pasture land, or 
cropland must equal or exceed the approved success standard during the 
growing season of any two years after year six of the responsibility 
period.
    (ii) On all other areas, the parameters must equal or exceed the 
applicable success standard during the growing season of the last year 
of the responsibility period.
    (2) Five full years for lands eligible for remining included in a 
permit approved under Sec.  785.25 of this chapter. The lands must 
equal or exceed the applicable ground cover standard during the growing 
seasons of the last two consecutive years of the responsibility period.
    (d) Normal husbandry practices. (1) The regulatory authority may 
approve selective husbandry practices, excluding augmented seeding, 
fertilization, or irrigation, provided it obtains prior approval from 
OSMRE in accordance with Sec.  732.17 of this chapter that the 
practices are normal husbandry practices, without extending the period 
of responsibility for revegetation success and bond liability, if those 
practices can be expected to continue as part of the postmining land 
use or if discontinuance of the practices after the liability period 
expires will not reduce the probability of permanent revegetation 
success.
    (2) Approved practices must be normal husbandry practices within 
the region for unmined lands having land uses similar to the approved 
postmining land use of the disturbed area, including such practices as 
disease, pest, and vermin control; and any pruning, reseeding, and 
transplanting specifically necessitated by such actions.


Sec.  817.116  What are the standards for determining revegetation 
success?

    (a) The regulatory authority must select standards for revegetation 
success and statistically valid sampling techniques for measuring 
revegetation success. The standards and techniques must be made 
available to the public in written form.
    (b) The standards for success applied to a specific permit must be 
adequate to demonstrate restoration of premining land use capability 
and must reflect the revegetation plan requirements of Sec.  784.12(g) 
of this chapter. They must be based upon the following data--
    (1) The plant community and vegetation information required under 
Sec.  783.19 of this chapter.
    (2) The soil type and productivity information required under Sec.  
783.21 of this chapter.
    (3) The land use capability and productivity information required 
under Sec.  783.22 of this chapter.
    (4) The postmining land use approved under Sec.  784.24 of this 
chapter, but only to the extent that the approved postmining land use 
actually will be implemented before expiration of the revegetation 
responsibility period. Otherwise, the site must be revegetated in a 
manner that will restore native plant communities and the revegetation 
success standards for the site must reflect that requirement.
    (c) Except for the areas identified in Sec.  817.111(a) of this 
part, standards for success must include--
    (1) Species diversity.
    (2) Areal distribution of species.
    (3) Ground cover, except for land actually used for cropland after 
the completion of regrading and redistribution of soil materials.
    (4) Production, for land used for cropland, pasture, or grazing 
land either before permit issuance or after the completion of regrading 
and redistribution of soil materials.
    (5) Stocking, for areas revegetated with woody plants.
    (d) The ground cover, production, or stocking of the revegetated 
area will be considered equal to the approved success standard for 
those parameters when the measured values are not less than 90 percent 
of the success standard, using a 90-percent statistical confidence 
interval (i.e., a one-sided test with a 0.10 alpha error).
    (e) For all areas revegetated with woody plants, regardless of the 
postmining land use), the regulatory authority must specify minimum 
stocking and planting arrangements on the basis of local and regional 
conditions and after coordination with and approval by the state 
agencies responsible for the administration of forestry and wildlife 
programs. Coordination and approval may occur on either a program-wide 
basis or a permit-specific basis.
    (f)(1) Only those species of trees and shrubs approved in the 
permit as part of the revegetation plan under Sec.  784.12(g) of this 
chapter or volunteer trees and shrubs of species that meet the 
requirements of Sec.  817.111(c) of this part may be counted in 
determining whether stocking standards have been met.
    (2)(i) At the time of final bond release under Sec.  800.42(d) of 
this chapter, at least 80 percent of the trees and shrubs used to 
determine success must have been in place for 60 percent of the 
applicable minimum period of responsibility under Sec.  817.115 of this 
part.
    (ii) Trees and shrubs counted in determining revegetation success 
must be healthy and have been in place for not less than two growing 
seasons. Any replanting must be done by means of transplants to allow 
for proper accounting of plant stocking.
    (iii)(A) For purposes of paragraph (f)(2)(ii) of this section, 
volunteer trees and shrubs of species that meet the requirements of 
Sec.  817.111(c) of this part may be deemed equivalent to planted 
specimens two years of age or older.
    (B) Suckers on shrubby vegetation can be counted as volunteer 
plants when it is evident the shrub community is vigorous and 
expanding.
    (iv) The requirements of paragraphs (f)(2)(i) and (ii) of this 
section will be deemed met when records of woody vegetation planted 
show that--
    (A) No woody plants were planted during the last two growing 
seasons of the responsibility period; and,
    (B) If any replanting of woody plants took place earlier during the 
responsibility period, the total number planted during the last 60 
percent of that period is less than 20 percent of the total number of 
woody plants required to meet the stocking standard.
    (3) Vegetative ground cover on areas planted with trees or shrubs 
must be of a nature that allows for natural establishment and 
succession of native plants, including trees and shrubs.
    (g) Special provision for areas that are developed within the 
revegetation responsibility period. Portions of the permit area that 
are developed for industrial, commercial, or residential use within the 
revegetation responsibility period need not meet production or stocking 
standards. For those areas, the vegetative ground cover must not be 
less than that required to control erosion.
    (h) Special provision for previously mined areas. Previously mined 
areas need only meet a vegetative ground cover standard, unless the 
regulatory authority specifies otherwise. At a minimum, the cover on 
the revegetated previously mined area must not be less than the ground 
cover existing before redisturbance and must be adequate to control 
erosion.
    (i) Special provision for prime farmland. For prime farmland, the 
revegetation success standard provisions of Sec.  823.15 of this 
chapter

[[Page 44695]]

apply in lieu of the requirements of paragraphs (b) through (h) of this 
section.


Sec.  817.121  What measures must I take to prevent, control, or 
correct damage resulting from subsidence?

    (a) Measures to prevent or minimize damage. (1) You, the permittee 
or operator, must either--
    (i) Adopt measures consistent with known technology that prevent 
subsidence from causing material damage to the extent technologically 
and economically feasible, maximize mine stability, and maintain the 
value and reasonably foreseeable use of surface lands; or
    (ii) Adopt mining technology that provides for planned subsidence 
in a predictable and controlled manner.
    (2) If you employ mining technology that provides for planned 
subsidence in a predictable and controlled manner under paragraph 
(a)(1)(ii) of this section, you must take necessary and prudent 
measures, consistent with the mining method employed, to minimize 
material damage to the extent technologically and economically feasible 
to non-commercial buildings and occupied residential dwellings and 
structures related thereto unless--
    (i) You have obtained the written consent of the owners of those 
structures; or
    (ii) The costs of those measures would exceed the anticipated costs 
of repair. This exception does not apply if the anticipated damage 
would constitute a threat to health or safety.
    (3) Nothing in this part prohibits the standard method of room-and-
pillar mining.
    (b) You must comply with all provisions of the subsidence control 
plan prepared pursuant to Sec.  784.30 of this chapter and approved in 
the permit.
    (c) Repair of damage to surface lands. To the extent 
technologically and economically feasible, you must correct any 
material damage resulting from subsidence caused to surface lands by 
restoring the land to a condition capable of maintaining the value and 
reasonably foreseeable uses that it was capable of supporting before 
subsidence damage occurred.
    (d) Repair or compensation for damage to non-commercial buildings 
and dwellings and related structures. (1) You must promptly repair, or 
compensate the owner for, material damage resulting from subsidence 
caused to any non-commercial building or occupied residential dwelling 
or structure related thereto that existed at the time of mining.
    (2) If you select the repair option, you must fully rehabilitate, 
restore, or replace the damaged structure.
    (3) If you select the compensation option, you must compensate the 
owner of the damaged structure for the full amount of the decrease in 
value resulting from the subsidence-related damage. You may provide 
compensation by the purchase, before mining, of a non-cancelable, 
premium-prepaid insurance policy.
    (4) The requirements of paragraph (d) of this section apply only to 
subsidence-related damage caused by underground mining activities 
conducted after October 24, 1992.
    (e) Repair or compensation for damage to other structures. To the 
extent required under applicable provisions of state law, you must 
correct material damage resulting from subsidence caused to any 
structures or facilities not protected by paragraph (d) of this section 
by either repairing the damage or compensating the owner of the 
structures or facilities for the full amount of the decrease in value 
resulting from the subsidence. Repair of damage includes 
rehabilitation, restoration, or replacement of damaged structures or 
facilities. Compensation may be accomplished by the purchase before 
mining of a non-cancelable, premium-prepaid insurance policy.
    (f) Information to be considered in determination of causation. The 
regulatory authority must consider all relevant and reasonably 
available information in determining whether damage to protected 
structures was caused by subsidence from underground mining.
    (g) Adjustment of bond amount for subsidence damage. (1) When 
subsidence-related material damage to land, structures or facilities 
protected under paragraphs (c) through (e) of this section occurs, or 
when contamination, diminution, or interruption to a water supply 
protected under Sec.  817.40 of this part occurs, the regulatory 
authority must require the permittee to post additional performance 
bond until the repair, compensation, or replacement is completed.
    (2) The amount of additional bond required under paragraph (g)(1) 
of this section must equal the--
    (i) Estimated cost of the repairs if the repair option is selected.
    (ii) Decrease in value if the compensation option is selected.
    (iii) Estimated cost to replace the protected water supply if the 
permittee will be replacing the water supply.
    (3) The requirements of paragraph (g)(1) of this section do not 
apply if repair, compensation, or replacement is completed within 90 
days of the occurrence of damage. The regulatory authority may extend 
the 90-day time frame, provided that the total time allowed does not 
exceed one year, if you demonstrate, and the regulatory authority finds 
in writing, that subsidence is not complete, that all probable 
subsidence-related material damage has not yet occurred, or that all 
reasonably anticipated changes that may affect the protected water 
supply have not yet occurred, and that therefore it would be 
unreasonable to complete the repair of the subsidence-related material 
damage to lands or protected structures or the replacement of the 
protected water supply within 90 days.
    (h) Prohibitions and limitations on underground mining. (1) You may 
not conduct underground mining activities beneath or adjacent to--
    (i) Public buildings and facilities.
    (ii) Churches, schools, and hospitals.
    (iii) Impoundments with a storage capacity of 20 acre-feet or more 
or bodies of water with a volume of 20 acre-feet or more.
    (2) The prohibitions of paragraph (h)(1) of this section do not 
apply if the subsidence control plan demonstrates that subsidence will 
not cause material damage to, or reduce the reasonably foreseeable use 
of, the features or facilities listed in paragraphs (h)(1)(i) through 
(iii) of this section.
    (3) The regulatory authority may limit the percentage of coal 
extracted under or adjacent to the features and facilities listed in 
paragraphs (h)(1)(i) through (iii) of this section if it determines 
that the limitation is necessary to minimize the potential for material 
damage to those features or facilities or to any aquifer or body of 
water that serves as a significant water source for any public water 
supply system.
    (i) If subsidence causes material damage to any of the features or 
facilities listed in paragraphs (h)(1)(i) through (iii) of this 
section, the regulatory authority may suspend mining under or adjacent 
to those features or facilities until the subsidence control plan is 
modified to ensure prevention of further material damage to those 
features or facilities.
    (j) The regulatory authority must suspend underground mining 
activities under urbanized areas, cities, towns, and communities, and 
adjacent to industrial or commercial buildings, major impoundments, or 
perennial streams, if it finds that the mining activities pose an 
imminent danger is found to inhabitants of the urbanized areas, cities, 
towns, or communities.
    (k) You must submit a detailed plan of the underground workings of 
your

[[Page 44696]]

mine in accordance with a schedule approved by the regulatory 
authority. The detailed plan must include maps and descriptions, as 
appropriate, of significant features of the underground mine, including 
the size, configuration, and approximate location of pillars and 
entries, extraction ratios, measures taken to prevent or minimize 
subsidence and related damage, areas of full extraction, and other 
information required by the regulatory authority. The regulatory 
authority may hold the information submitted with the detailed plan as 
confidential, in accordance with Sec.  773.6(d) of this chapter, upon 
your request.


Sec.  817.122  How and when must I provide notice of planned 
underground mining?

    (a) At least 6 months prior to mining, or within that period if 
approved by the regulatory authority, you, the underground mine 
operator, must mail a notification to all owners and occupants of 
surface property and structures above the planned underground workings.
    (b) The notification must include, at a minimum--
    (1) Identification of specific areas in which mining will take 
place;
    (2) Dates that specific areas will be undermined; and
    (3) The location or locations where the subsidence control plan may 
be examined.

operations?

    (a)(1) Each person who temporarily ceases to conduct underground 
mining activities at a particular site must effectively support and 
maintain all surface access openings to underground operations and 
secure surface facilities in areas in which there are no current 
operations, but where operations are to be resumed under an approved 
permit.
    (2) Temporary cessation does not relieve a person of his or her 
obligation to comply with any provisions of the approved permit.
    (b)(1) You must submit a notice of intent to temporarily cease 
operations to the regulatory authority before ceasing mining and 
reclamation operations for 30 or more days, or as soon as you know that 
a temporary cessation will extend beyond 30 days.
    (2) The notice of temporary cessation must include a statement of 
the--
    (i) Exact number of surface acres disturbed within the permit area 
prior to temporary cessation;
    (ii) Extent and kind of reclamation accomplished before temporary 
cessation; and
    (iii) Backfilling, regrading, revegetation, environmental 
monitoring, underground opening closures, and water treatment 
activities that will continue during temporary cessation.


Sec.  817.132  What actions must I take when I permanently cease mining 
operations?

    (a) Persons who permanently cease conducting underground mining 
activities at a particular site must close, backfill, or otherwise 
permanently reclaim all disturbed areas in accordance with this chapter 
and the permit approved by the regulatory authority.
    (b) All underground openings, surface equipment, surface 
structures, or other surface facilities must be removed and the 
affected land reclaimed, unless the regulatory authority approves 
retention of those features because they are suitable for the 
postmining land use or environmental monitoring.


Sec.  817.133  What provisions concerning postmining land use apply to 
my operation?

    Except as provided in Sec.  784.24(c) of this chapter, you, the 
permittee, must restore all disturbed areas in a timely manner to 
conditions that are capable of supporting--
    (a) The uses they were capable of supporting before any mining; as 
described under Sec.  783.22 of this chapter; or
    (b) Higher or better uses approved under Sec.  784.24(b) of this 
chapter.


Sec.  817.150  What are the general standards for haul and access 
roads?

    (a) Road classification system. (1) Each road meeting the 
definition of that term in Sec.  701.5 of this chapter must be

    (2) A road damaged by a catastrophic event, such as a flood or 
earthquake, must be repaired as soon as is practicable after the damage 
has occurred.
    (f) Reclamation. A road not to be retained as part of an approved 
postmining land use must be reclaimed in accordance with the approved 
reclamation plan as soon as practicable after it is no longer needed 
for mining and reclamation operations. Reclamation must include--
    (1) Closing the road to traffic.

[[Page 44697]]

    (2) Removing all bridges and culverts unless approved as part of 
the postmining land use.
    (3) Removing or otherwise disposing of road-surfacing materials 
that are incompatible with the postmining land use and revegetation 
requirements.
    (4) Reshaping the slopes of road cuts and fills as necessary to be 
compatible with the postmining land use and to complement the natural 
drainage pattern of the surrounding terrain.
    (5) Protecting the natural drainage patterns by installing dikes or 
cross-drains as necessary to control surface runoff and erosion.
    (6) Scarifying or ripping the roadbed, replacing topsoil or 
substitute material in accordance with Sec.  817.22 of this part, and 
revegetating disturbed surfaces in accordance with Sec. Sec.  817.111,

    (a) Primary roads must meet the requirements of Sec.  817.150 of 
this part and the additional requirements of this section.
    (b) Certification. The construction or reconstruction of primary 
roads must be certified in a report to the regulatory authority by a 
qualified registered professional engineer, or in any state that 
authorizes land surveyors to certify the construction or reconstruction 
of primary roads, a qualified registered professional land surveyor, 
with experience in the design and construction of roads. The report 
must indicate that the primary road has been constructed or 
reconstructed as designed and in accordance with the approved plan.
    (c) Safety factor. Each primary road embankment must have a minimum 
static factor of 1.3 or meet the requirements established under Sec.  
784.37(c) of this chapter.
    (d) Location. (1) To minimize erosion, a primary road must be 
located, insofar as is practicable, on the most stable available 
surface.
    (2) Fords of perennial or intermittent streams are prohibited 
unless they are specifically approved by the regulatory authority as 
temporary routes during periods of road construction.
    (e) Drainage control. In accordance with the approved plan--
    (1) Each primary road must be constructed (or reconstructed) and 
maintained to have adequate drainage control, using structures such as, 
but not limited to bridges, ditches, cross drains, and ditch relief 
drains. The drainage control system must be designed to safely pass the 
peak runoff from the 10-year, 6-hour precipitation event, or any 
greater event specified by the regulatory authority.
    (2) Drainage pipes and culverts must be installed as designed, and 
maintained in a free and operating condition and to prevent or control 
erosion at inlets and outlets.
    (3) Drainage ditches must be constructed and maintained to prevent 
uncontrolled drainage over the road surface and embankment.
    (4) Culverts must be installed and maintained to sustain the 
vertical soil pressure, the passive resistance of the foundation, and 
the weight of vehicles using the road.
    (5) Natural stream channels must not be altered or relocated 
without the prior approval of the regulatory authority in accordance 
with Sec.  784.28 of this chapter and Sec.  817.57 of this part.

structures for perennial or intermittent stream channel crossings must 
be made using bridges, culverts, low-water crossings, or other 
structures designed, constructed, and maintained using current prudent 
engineering practices. The regulatory authority must ensure that low-
water crossings are designed, constructed, and maintained to prevent 
erosion of the structure or streambed and additional contributions of 
suspended solids to streamflow.
    (f) Surfacing. Primary roads must be surfaced with material 
approved by the regulatory authority as being sufficiently durable for 
the anticipated volume of traffic and the weight and speed of vehicles 
using the road.


Sec.  817.180  To what extent must I protect utility installations?

    You must conduct all underground coal mining operations in a manner 
that minimizes damage, destruction, or disruption of services provided 
by oil, gas, and water wells; oil, gas, and coal-slurry pipelines; 
railroads; electric and telephone lines; and water and sewage lines 
that pass over, under, or through the permit area, unless otherwise 
approved by the owner of those facilities and the regulatory authority.


Sec.  817.181  What requirements apply to support facilities?

    (a) You must operate each support facility in accordance with the 
permit issued for the mine or coal preparation plant to which the

the regulatory authority has approved a permit under Sec.  785.14 of 
this chapter.
    (b) Performance standards. (1) You, the permittee, must comply with 
all applicable requirements of this subchapter and the regulatory 
program, other than the approximate original contour restoration 
requirements of Sec.  816.102(a)(1) of this chapter and the thick 
overburden requirements of Sec.  816.105 of this chapter.
    (2)(i) You must retain an outcrop barrier, consisting of the toe of 
the lowest coal seam and its associated overburden, of sufficient width 
to prevent slides and erosion. You must construct drains through the 
barrier to the extent necessary to prevent saturation of the backfill.
    (ii) The outcrop barrier requirement in paragraph (b)(2)(i) of this 
section does not apply if the proposed mine site was mined prior to May 
3, 1978, and the toe of the lowest coal seam has already been removed.
    (iii) You may remove a coal barrier adjacent to a head-of-hollow 
fill after the elevation of the fill attains the elevation of the coal 
barrier if the head-of-hollow fill provides the stability otherwise 
ensured by the retention of a coal barrier.
    (iv) The regulatory authority may allow removal of the outcrop 
barrier required by paragraph (b)(2)(i) of this section if the 
regulatory program establishes standards for and requires construction 
of a barrier comprised of alternative materials that will provide 
equivalent stability.

[[Page 44698]]

    (3) The final graded slopes must be less than 1v:5h, so as to 
create a level plateau or gently rolling configuration. The outslopes 
of the plateau may not exceed 1v:2h except where engineering data 
substantiate, and the regulatory authority finds in writing and
