Purpose A. Proposed Action In July 2011, the EPA issued the Indian Country Minor NSR rule that established, among other things, the requirements and process for the preconstruction permitting of minor sources in Indian country. Under the rule, on or after September 2, 2014, an owner or operator must obtain a preconstruction permit from the reviewing authority 1 if the source will 1 In this document, reviewing authority refers to an EPA regional office. However, tribes can become E:\FR\FM\17JYP5.SGM 17JYP5 Federal Register / Vol. 79, No. 137 / Thursday, July 17, 2014 / Proposed Rules emcdonald on DSK67QTVN1PROD with PROPOSALS5 construct a new true minor source,2 or will modify an existing true minor source in Indian country. The rule also specified the process and requirements for using general permits as a streamlined permitting approach to authorize construction and modifications at true minor sources. General permits streamline the preconstruction permitting of new or modified true minor sources because they involve the issuance of one permit that can apply to multiple stationary sources that have similar emissions units. On January 14, 2014, the EPA proposed general permits 3 for use in Indian country pursuant to the Indian Country Minor NSR rule for new or modified true minor sources in the following five source categories: Hot mix asphalt plants; stone quarrying, crushing, and screening facilities; auto body repair and miscellaneous surface coating operations; gasoline dispensing facilities (GDFs); and petroleum dry cleaning facilities. In the alternative, the EPA also proposed permits by rule for use in Indian country for new or modified minor sources in three of the source categories: Auto body repair and miscellaneous surface coating operations; GDFs; and petroleum dry cleaning facilities. The EPA also proposed certain changes to the Indian Country Minor NSR rule. The proposed changes include: Extending the deadline by when true minor sources in the oil and gas sector must receive minor source NSR permits; and allowing general permits and permits by rule for specific categories to be used to create synthetic minor sources. In the prior action, we also sought comment on a number of issues, some of which relate reviewing authorities if they decide to assume responsibility for implementing the minor NSR program in their area and are either delegated authority to implement the Indian Country Minor NSR rule or establish and obtain the EPA’s approval of their own minor source program. 2 True minor source means a source that emits, or has the potential to emit, regulated NSR pollutants in amounts that are less than the major source thresholds under either the Prevention of Significant Deterioration program at 40 CFR 52.21, or the Major NSR Program for Nonattainment Areas in Indian Country at 40 CFR 49.166 through 49.173, but equal to or greater than the minor NSR thresholds in 40 CFR 49.153, without the need to take an enforceable restriction to reduce its potential to emit (PTE) to such levels. The PTE includes fugitive emissions, to the extent that they are quantifiable, only if the source belongs to one of the 28 source categories listed in part 51, Appendix S, paragraph II.A.4(iii) or 40 CFR 52.21(b)(1)(iii), as applicable. 3 ‘‘General Permits and Permits by Rule for the Federal Minor New Source Review Program in Indian Country,’’ U.S. Environmental Protection Agency, January 14, 2014 (79 FR 2546), https:// www.gpo.gov/fdsys/pkg/FR-2014-01-14/pdf/201330345.pdf. VerDate Mar<15>2010 17:53 Jul 16, 2014 Jkt 232001 to the source categories contained in this proposal. Today’s proposal addresses a second group of activities; the EPA is proposing the use of two types of minor NSR preconstruction permits to help streamline permitting of true minor sources that construct or modify in Indian country and that belong to one of six additional source categories. The first type of permit is a general permit. A general permit is a document that the EPA will make available online that will contain all of the emissions limitations, monitoring, recordkeeping and reporting requirements to which a source in a given source category would be subject. Sources seeking coverage under a tribal general permit will need to submit a request for coverage or application to the EPA. The second type is a permit by rule, which uses a regulatory-type structure to permit sources by pre-authorizing construction and modification activities carried out in accordance with the permit’s requirements. Sources seeking coverage under a tribal permit by rule must notify the EPA that it meets the terms of coverage and is complying with the permit’s conditions, but does not need to await approval of a request for coverage. As our preferred approach, we are proposing general permits for the six source categories: Concrete batch plants; boilers; stationary spark ignition engines; stationary compression ignition engines; graphic arts and printing operations; and sawmills. Specifically, we are proposing general permits for these source categories for permitting affected emissions units and emissionsgenerating activities in these source categories. As an alternative, for graphic arts and printing operations, the EPA is also requesting comment on whether, in lieu of establishing a general permit, we should instead adopt a permit by rule. We are making available various permit implementation documents and tools on which we request public comment. In a prior action 4 in which we also proposed general permits and permits by rule for certain source categories of minor sources in Indian country, we proposed the regulatory framework that the EPA will use to establish permits by rule. That proposed regulatory framework is also relevant here. 4 ‘‘General Permits and Permits by Rule for the Federal Minor New Source Review Program in Indian Country,’’ U.S. Environmental Protection Agency, January 14, 2014 (79 FR 2546), https:// www.gpo.gov/fdsys/pkg/FR-2014-01-14/pdf/201330345.pdf. PO 00000 Frm 00005 Fmt 4701 Sfmt 4702 41849 B. Areas Where the EPA Is Seeking Comment In this proposal, we are seeking comment on the following areas: (1) All aspects of the permit documents and implementation tools of the following six source categories (Sections VI. and IX.): a. Concrete batch plants; b. Boilers; c. Stationary compression ignition engines; d. Stationary spark ignition engines; e. Graphic arts and printing operations; and f. Sawmills. (2) The appropriateness of using a streamlined general permit/permit by rule application for one source category (Section IX.): a. Graphic arts and printing operations. (3) Different aspects of the EPA’s conclusion on its control technology review that, because the control measures in this proposal are currently used by other similar sources in other areas of the country, the measures in the proposed permits are technically and economically feasible, and cost effective (Section V.); (4) The process for sources to address the requirements of the Endangered Species Act (ESA) and the National Historic Preservation Act (NHPA) with respect to the six categories in today’s proposal (Sections V. and VII.); (5) Use of throughput limits and capacity limits as surrogate for tons per year (tpy) allowable emission limitations, or, alternatively, establishment of annual allowable emission limitations for each pollutant, and the use of throughput limits as surrogate monitoring measures to demonstrate compliance with tpy annual allowable emission limitations (Sections V. and VI.); (6) Finalizing both permitting mechanisms for graphic arts and printing operations by providing authorization to construct or modify true minor sources in this category via permits by rule and by providing enforceable limitations to create synthetic minor sources in this category via general permits (Section X.); and (7) Proposed rule changes to the Indian Country Minor NSR rule in one area (Section XI.): a. Shortening the general permit application review process from 90 to 45 days for one source category out of the six in this proposal for which the EPA believes it is appropriate: i. Graphic arts and printing operations. In this proposal, we are not seeking comment on several issues already E:\FR\FM\17JYP5.SGM 17JYP5 emcdonald on DSK67QTVN1PROD with PROPOSALS5 41850 Federal Register / Vol. 79, No. 137 / Thursday, July 17, 2014 / Proposed Rules proposed in the January 14, 2014, action that more broadly cover policy and other issues related generally to the functioning and use of general permits and permits by rule in Indian country. The Agency’s final decision on those issues, though, has the potential to impact sources in the source categories proposed in this action. Those issues include the following: (1) Several administrative aspects of general permits, including: a. Whether the EPA’s proposed approach of incorporating by reference each reviewing authority’s approval of a request for coverage into the general permit is necessary and appropriate; and b. The appropriateness of proposed permit terms related to the reviewing authority’s ability to reopen, revise, or terminate an individual approval of coverage under the general permit; (2) The regulatory framework that the EPA is proposing as an alternative to use to establish permits by rule and the streamlined review and issuance process that the EPA is proposing whereby a source can become covered by a permit by rule by notifying the EPA that it qualifies for the permit, meets the terms of coverage and is complying with the permit’s conditions (but not having to wait for the reviewing authority’s approval); (3) Proposal to change the policy in the Indian Country Minor NSR rule to allow the use of both general permits and permits by rule to create synthetic minor sources; (4) Use of more than one general permit and/or permit by rule for a source at a single location; (5) Additional source categories for which the EPA is planning to propose general permits and/or permits by rule; and (6) Proposed rule changes to the Indian Country Minor NSR rule in four areas in three provisions: a. Adjusting the deadline by which minor sources covered by a general permit need to obtain a preconstruction permit; b. Extending the permitting deadline for true minor sources within the oil and gas source category; c. Removing a provision to make clear that sources may seek coverage under a general permit as soon as it is effective and need not wait an additional 4 months; and d. Adjusting the deadline for oil and gas sources for certain registrationrelated requirements to be consistent with the proposed permitting deadline extension. VerDate Mar<15>2010 17:53 Jul 16, 2014 Jkt 232001 III. Background A. Tribal Air Rule On February 12, 1998,5 the EPA used its authority under section 301(d) of the Clean Air Act (CAA) to find that we would not treat tribal governments the same as states with respect to specific plan submittal and implementation deadlines under the CAA for National Ambient Air Quality Standards (NAAQS)-related requirements. This finding applied to many section 110 requirements, including requirements under section 110(a)(2)(c) to submit a program to regulate the modification and construction of any stationary source as necessary to ensure that the NAAQS are achieved. Although we determined that Indian tribes were not obligated to implement a permitting program, the EPA also made clear that we continue to have a general obligation under the CAA to ensure the protection of air quality throughout Indian country. To that end, we also used our authority under sections 301(a) and 301(d)(4) to establish a requirement to promulgate such federal implementation plan (FIP) provisions as are necessary or appropriate to protect air quality in Indian country (40 CFR 49.11(a)). For a number of years, the only federal CAA NSR permitting program that applied in Indian country was the major NSR program for areas meeting the NAAQS (‘‘attainment’’ areas) or areas for which there is insufficient information to determine whether they meet the NAAQS (‘‘unclassifiable’’ areas). We call this program the Prevention of Significant Deterioration (PSD) program (40 CFR 52.21). No federal NSR permitting program has covered minor sources or major sources in nonattainment areas. Nor was there a readily available way for major sources to take enforceable limits and become synthetic minor sources. On August 21, 2006, the EPA proposed the regulation: ‘‘Review of New Sources and Modifications in Indian Country’’ (i.e., the Indian Country NSR rule).6 Within this regulation, the EPA proposed to protect air quality in Indian country by establishing a FIP program to regulate the modification and construction of minor stationary sources consistent with the requirements of section 110(a)(2)(c) 5 ‘‘Indian Tribes: Air Quality Planning and Management,’’ U.S. Environmental Protection Agency, February 12, 1998 (63 FR 7254), https:// www.gpo.gov/fdsys/pkg/FR-1998-02-12/pdf/983451.pdf. 6 ‘‘Review of New Sources and Modifications in Indian Country,’’ U.S. Environmental Protection Agency, August 21, 2006 (71 FR 48696), https:// www.gpo.gov/fdsys/pkg/FR-2006-08-21/html/066926.htm. PO 00000 Frm 00006 Fmt 4701 Sfmt 4702 of the CAA. We call this part of the Indian Country NSR rule the Indian Country Minor NSR rule. Under the Indian Country Minor NSR rule, we proposed to fill a regulatory gap and provide a mechanism for issuing preconstruction permits for the construction of new minor sources and certain modifications of major and minor sources in Indian country. In developing the rule, the EPA conducted extensive outreach and consultation and provided an extensive public comment period that ended on March 20, 2007. The comments we received provided detailed information specific to Indian country and the final Indian Country Minor NSR rule incorporated many of the suggestions we received. We promulgated final rules on July 1, 2011,7 and the FIP became effective on August 30, 2011.8 B. Indian Country Minor NSR Rule 1. What is the Indian Country Minor NSR rule? The Indian Country Minor NSR rule applies to new and modified minor stationary sources and to minor modifications at existing major stationary sources located in Indian country where there is no EPAapproved program in place. The rule also includes a pre-construction permits program for major sources proposing to construct in areas of Indian country that have not attained one or more NAAQS, i.e., nonattainment areas. After September 2, 2014, any new stationary sources that will emit, or will have the PTE, a regulated NSR pollutant in amounts that will be: (1) Equal to or greater than the minor NSR thresholds, established in the Indian Country Minor NSR rule; and (2) less than the amount that would qualify the source as a major source for purposes of the PSD or nonattainment major NSR programs, 7 ‘‘Review of New Sources and Modifications in Indian Country,’’ U.S. Environmental Protection Agency, July 1, 2011 (76 FR 38748), https:// www.federalregister.gov/articles/2011/07/01/201114981/review-of-new-sources-and-modifications-inindian-country. 8 On January 17, 2014, the United States Court of Appeals for the District of Columbia Circuit issued an opinion and judgment vacating the Indian Country NSR rule with respect to non-reservation areas of Indian country. As a result, EPA does not currently have minor source NSR permitting authority in non-reservation areas of Indian country and any general permits and permits by rule issued under the Indian Country Minor NSR rule will not be immediately available in such areas of Indian country. Importantly, the court’s decision does not affect the Indian Country Minor NSR rule with respect to reservations, whether formal or informal, and any final general permits and permits by rule issued under the Indian Country Minor NSR rule will be available in those areas. The EPA is currently considering, but has not yet determined, how best to implement the court’s decision. E:\FR\FM\17JYP5.SGM 17JYP5 41851 Federal Register / Vol. 79, No. 137 / Thursday, July 17, 2014 / Proposed Rules must apply for and obtain a minor NSR permit before commencing construction of the new source. Likewise, any existing stationary source (minor or major) must apply for and obtain a minor NSR permit before commencing construction of a physical or operational change that will increase the allowable emissions of the stationary source by more than the specified minor NSR threshold amounts, if the change does not otherwise trigger the permitting requirements of the PSD or nonattainment major NSR program(s).9 Among other things, the Indian Country Minor NSR rule created a framework for the EPA to streamline the issuance of preconstruction permits to true minor sources by using general permits. We explain this framework further in the sections below. 2. What is a true minor source and how does it differ from a synthetic minor source? ‘‘True minor source’’ means a source that emits, or has the potential to emit, regulated NSR pollutants in amounts that are less than the major source thresholds under either the PSD program at 40 CFR 52.21, or the Major NSR program for Nonattainment Areas in Indian Country at 40 CFR 49.166 through 49.173, but equal to or greater than the minor NSR thresholds in 40 CFR 49.153, without the need to take an enforceable restriction to reduce its PTE to such levels. The PTE includes fugitive emissions, to the extent that they are quantifiable, only if the source belongs to one of the 28 source categories listed in 40 CFR part 51, Appendix S, paragraph II.A.4(iii) or 40 CFR 52.21(b)(1)(iii), as applicable. For example, a hot mix asphalt facility, located in a sulfur dioxide (SO2) attainment area, that has a maximum potential to emit of 135 tpy of SO2, without the need to take an enforceable restriction to reduce its PTE to such levels, would qualify as a true minor source. By contrast, ‘‘synthetic minor source’’ means a source that otherwise has the potential to emit regulated NSR pollutants in amounts that are at or above those for major sources, but that has taken a restriction so that its PTE is less than such amounts. Such restrictions must be enforceable as a legal and practical matter. For example, a hot mix asphalt facility, located in an SO2 attainment area, that has an unrestricted PTE of 270 tpy, but that is legally constrained to emit only 135 tpy of SO2 because the source has taken a throughput limit made enforceable through a permit (i.e., a limit on how much hot mix product it can produce), would qualify as a synthetic minor source. In the preamble to both the proposed and final Indian Country Minor NSR rule, the EPA indicated that it would not use general permits to allow otherwise major sources to create synthetic minor sources.10 3. What are the minor NSR thresholds? The ‘‘minor NSR thresholds’’ establish cutoff levels for each regulated NSR pollutant. If a source naturally has a PTE in amounts lower than the thresholds, then it is exempt from the Indian Country Minor NSR rule (see Table 2 and 40 CFR 49.153) for that pollutant. New or modified sources which naturally have a PTE in amounts that are: (1) Equal to or greater than the minor NSR thresholds; and (2) less than the major NSR thresholds (generally 100 to 250 tpy) are ‘‘minor sources’’ of emissions and subject to the Indian Country Minor NSR rule requirements at 40 CFR 49.151 through 161.

If the source straddles the two areas, the more stringent thresholds apply. 12 In extreme ozone nonattainment areas, section 182(e)(2) of the CAA requires any change at a major source that results in any increase in emissions to be subject to major NSR permitting. In other words, any changes to existing major sources in extreme ozone nonattainment areas are subject to a ‘‘0’’ tpy threshold, but that threshold does not apply to minor sources. 13 Id. PO 00000 Frm 00007 Fmt 4701 Sfmt 4702 E:\FR\FM\17JYP5.SGM 17JYP5 emcdonald on DSK67QTVN1PROD with PROPOSALS5 41852 Federal Register / Vol. 79, No. 137 / Thursday, July 17, 2014 / Proposed Rules general permit for categories of emissions units or stationary sources that are similar in nature, have substantially similar emissions, and would be subject to the same or substantially similar permit requirements.14 ‘‘Similar in nature’’ refers to size, processes, and operating conditions. The purpose of a general permit is to provide for protection of air quality while simplifying the permit process for similar minor sources. General permits offer a cost-effective means of issuing permits and provide a quicker and simpler mechanism for permitting minor sources than the sitespecific permitting process. While the final Indian Country Minor NSR rule contemplated issuance of general permits by the EPA regions, we have determined (for the permits on which we are taking comment here) that a nationwide action is appropriate. Through this action, we are proposing to issue general permits to serve as preconstruction permit authorizations that contain emission limitations and other restrictions to govern how a source may construct, modify and operate. National general permits streamline the permit issuance process by establishing universal requirements through one notice for specific types of emissions activities at multiple sources across the country. The EPA believes that the general permit approach is appropriate for the source categories in today’s proposal where the control equipment or techniques are generally similar from region to region. A general permit also allows a reviewing authority to notify the public through one notice that it intends to apply these requirements to any eligible source that seeks coverage under the permit in the future. This minimizes the burden on reviewing authorities’ resources by eliminating the need to issue separate permits for each individual minor source within the source type or category covered by the general permit. Use of a general permit also decreases the time required for an individual minor source to obtain a preconstruction permit because the application process is standardized. The Indian Country Minor NSR rule describes the process the EPA will use to issue general permits for the minor NSR program. A general permit must be issued in accordance with the requirements in 40 CFR 49.156. Briefly, these requirements address public 14 ‘‘Review of New Sources and Modifications in Indian Country,’’ U.S. Environmental Protection Agency, July 1, 2011 (76 FR 38770), https:// www.federalregister.gov/articles/2011/07/01/2011– 14981/review-of-new-sources-and-modifications-inindian-country. VerDate Mar<15>2010 17:53 Jul 16, 2014 Jkt 232001 availability of information, public notification and participation, and public comments. In addition, as discussed in Section IX., we are providing implementation tools to guide sources through a series of questions to determine whether they meet the criteria to be eligible for coverage under a general permit. C. What is a permit by rule? Like a general permit, a permit by rule is a standard set of requirements that can apply to multiple stationary sources with similar emissions characteristics. For purposes of this action, a permit by rule would differ from a general permit in that the agency would codify a permit by rule directly into the Indian Country Minor NSR rule. The process for a source to apply for coverage under a permit by rule, and the process for the reviewing authority to grant coverage under a permit by rule, is more streamlined compared to a standard general permit, or a site-specific permit. In particular, a proposed project need not wait for a response from the permitting authority before starting construction under a permit by rule. Section VII. provides a description of the source application process for permits by rule. IV. Description of General Permit Program in Indian Country and the EPA’s Use of This Package To Satisfy the General Permit Issuance Process A. General Permit Program The EPA codified the framework it would follow to issue general permits for minor sources in the Indian Country Minor NSR rule in 40 CFR 49.156. While it was not necessary for the EPA to codify this framework to issue general permits, the EPA nonetheless created the regulatory framework to better inform the public of the process the EPA will use to issue general permits. Per the framework, to issue a general permit, the reviewing authority must follow the requirements for public participation contained in 40 CFR 49.157. These provisions require the reviewing authority then to provide a notice that a draft permit is available for comment. The regulations list a number of ways in which a reviewing authority can provide notice to the public, and also allow the reviewing authority to use other means of notification as appropriate (40 CFR 49.157(b)(1)(ii)(E)). We have opted to provide notice to the public regarding the present proposal of general permits for six source categories through use of the Federal Register. We believe this approach is appropriate in this case because we intend to apply PO 00000 Frm 00008 Fmt 4701 Sfmt 4702 these general permits in all areas of Indian country subject to the Indian Country Minor NSR Program and the Federal Register provides a nationwide circulation of the notice. We will also mail a copy of each permit for which the reviewing authority has approved coverage for a source to the appropriate Indian governing bodies and the tribal, state and local air pollution agencies in adjacent air jurisdictions that may be impacted by the air pollution sources that use the general permit in accordance with 40 CFR 49.157(b)(1)(i). The existing regulations also identify the type of information that a reviewing authority must make available to the public, and list a number of elements to be included in the public notice (40 CFR 49.157(a) and (b)(2)). We are satisfying these requirements in this proposal in a wide-ranging manner by providing the public access to the application forms we will require an applicant to complete, and the other implementation tools for each general permit. (We discuss these tools in greater detail in Section IX. of this preamble.) Many of these requirements relate to information that is best made available when an individual applicant applies for coverage under a specific general permit. We will make information specific to an individual source’s request for coverage under a general permit available at the time we provide notice of the source’s request for coverage. After providing adequate public notice of the availability of the draft permit, the reviewing authority must allow a period of at least 30 days for the public to comment on the permit, and to request a public hearing (40 CFR 49.157). We are satisfying these requirements by using this proposed rule to propose, take comments and hold a public hearing on the general permits. Once we finalize a general permit, it will be used by the EPA’s regional office reviewing authorities 15 for sources requesting coverage under the permit. The regulations set forth the provisions for a final permit to undergo administrative and judicial review in accordance with 40 CFR 49.159. The procedures governing appeals of NSR permits to the Environmental Appeals Board will govern administrative review of these general permits. Issuance of a general permit is a final agency action with respect to all aspects of the general 15 The Administrator delegated the authority to each of the EPA Regional Administrators to carry out all aspects of the Indian Country Minor NSR program, including issuing general permits and approving individual coverage under a general permit.

The provisions of 40 CFR 49.159 will continue to govern administrative and judicial review of the EPA’s approval of an individual source’s request for coverage. After the reviewing authority approves a request for coverage by an individual source, a party may appeal only the applicability of the general permit to that particular source. Although we are using a Federal Register notice to initially establish the general permits, we intend to use other methods also consistent with procedures in 40 CFR 49.159 to reopen or administratively amend the final permits if we determine it is necessary and appropriate. A reviewing authority may reopen and revise a final general permit for cause after providing the opportunity for notice and comment under 40 CFR 49.157. Revisions to a final general permit may be appropriate, for example, when the reviewing authority decides to issue a new general permit for the same category to account for advances in control technology or for other pertinent reasons. However, when a reviewing authority issues a new general permit, sources operating under the existing general permit will be able to continue to operate under the existing permit unless and until the source subsequently proposes to modify.16 B. How do sources apply for general permits? 40 CFR 49.156(e) describes the procedure for sources to obtain coverage under a general permit. At the time a source submits a request for coverage under a general permit, it must submit a copy of such request to the appropriate Indian governing body for the area of Indian country where the source is locating. The reviewing authority must act on the source’s request for coverage under the general permit as expeditiously as possible, but it must notify the source of the final decision within 90 days of its receipt of the coverage request. The source’s reviewing authority must comply with a 45-day completeness review period to determine if the request for coverage under a general permit is complete. Therefore, within 30 days after the receipt of the source’s coverage request, the reviewing authority must make an initial request for any additional information necessary to process the 16 If the EPA revises an existing general permit, then the original permit can no longer be used for new and modified minor sources. The new general permit will be used for new and modified minor sources in the relevant source category. The existing general permit remains in place for existing facilities unless and until they choose to modify. VerDate Mar<15>2010 17:53 Jul 16, 2014 Jkt 232001 coverage request and the source must submit such information within 15 days. If the source does not submit the requested information within 15 days from the request for additional information and this results in a delay that is beyond the 45-day completeness review period, the 90-day permit issuance period for the general permit will be extended by the additional days the source takes to submit the requested information beyond the 45-day period. If the reviewing authority fails to notify the source within a 30-day period of any additional information necessary to process the source’s coverage request, the source will still have 15 days to submit such information and the reviewing authority must still grant or deny the request for coverage under a general permit within the 90-day general permit issuance period and without any time extension. If the reviewing authority determines that the source’s request for coverage under a general permit has all the relevant information and is complete, it will notify the source in writing as soon as that determination is made. If the source does not receive from the reviewing authority a request for additional information or a notice that the request for coverage under a general permit is complete within the 45-day completeness review period, the request will be deemed complete. After permit coverage is granted, under 40 CFR 49.156(e), coverage under a general permit becomes invalid if a source does not commence construction within 18 months after the effective date of coverage under a general permit, if the source discontinues construction for a period of 18 months or more, or if the source does not complete construction within a reasonable time. The reviewing authority may extend the 18-month period upon a satisfactory showing that an extension is justified, and the 18month limit does not apply to the time period between construction of the approved phases of a phased construction project. In those cases, construction of each such phase must commence within 18 months of the projected and approved commencement date. In Section XI., the EPA proposes to amend 40 CFR 49.156(e) to shorten the permit application procedure to 45 from 90 days for one source category in today’s proposal: Graphic arts and printing operations. In Section IX., we describe the implementation documents and tools that we are making available for comment to assist sources with applying for general permits. PO 00000 Frm 00009 Fmt 4701 Sfmt 4702 41853 C. What are the required permitting elements? For general permits, these elements are discussed in the Indian Country Minor NSR rule promulgated at 40 CFR 49.155(a) and include: • The effective date of the permit and the date by which a source must commence construction in order for the permit’s coverage to remain valid (i.e., 18 months after the source obtains coverage under the general permit); • The emissions units subject to the permit and their associated emission limitations (and other permit conditions); • Monitoring, recordkeeping, reporting and testing requirements to ensure compliance with the emission limitations; and • A severability clause to ensure the continued validity of the other portions of the permit in the event of a challenge to a portion of the permit. V. Source Categories for Which Proposed General Permits in Indian Country Are Available for Public Review A. Notice of Proposed General Permits In accordance with 40 CFR 49.171(b)(1)(1)(E), we are providing the public with a copy of six proposed general permits covering six source categories: (1) Concrete batch plants, (2) boilers, (3) stationary spark ignition engines, (4) stationary compression ignition engines, (5) graphic arts and printing operations and (6) sawmills. Copies of each of these proposed permits and the following four associated permitting documents are available in the docket for this notice (EPA–HQ–OAR–2011–0151) and at https://www.epa.gov/air/tribal/ tribalnsr.html: (1) Request for Coverage (Application); (2) Questionnaire; (3) Instructions; and (4) PTE calculator. The application for one of the six source categories in today’s proposal (i.e., graphic arts and printing operations) is streamlined and asks for contact and location information and basic solvent usage information (more detailed source-specific information would be required from sources seeking coverage under the other five general permits). This is discussed further in Section IX. The general permits will authorize 17 construction of, or any modifications of, 17 To be eligible for a proposed general permit in today’s action, the PTE of your facility, including E:\FR\FM\17JYP5.SGM Continued 17JYP5 emcdonald on DSK67QTVN1PROD with PROPOSALS5 41854 Federal Register / Vol. 79, No. 137 / Thursday, July 17, 2014 / Proposed Rules any of the affected emission units, or pollutant emitting activities named in the permit, at any proposed true minor source that meets the permit’s applicability requirements and eligibility statements, and for which the reviewing authority approves coverage under the permit. We request comment on all aspects of the general permits and the associated forms and documentation provided to assist the stationary sources specified in the permits in complying with the Indian country minor NSR preconstruction permitting and postconstruction operating requirements. In Section VIII., we propose, in the alternative, a permit by rule for graphic arts and printing operations. Should we decide to finalize a permit by rule for this category, then we may not finalize the draft general permit for that category. Alternatively, we may opt to finalize both permitting mechanisms for this source category, and may tailor one of the permitting mechanisms to provide authorization to construct or modify true minor sources (i.e., permit by rule) and another to provide enforceable limitations to create synthetic minor sources (i.e., general permit). We specifically request comment on this ‘‘hybrid’’ approach (see Section XI. of the January 14, 2014 proposal 18 for further discussion on the hybrid approach). For the six source categories in today’s action, we are proposing general permits as our preferred approach. We have crafted our proposal to ensure air quality is protected and to provide more detailed or streamlined approaches, as appropriate. For concrete batch plants, boilers, stationary spark ignition engines, stationary compression ignition engines and sawmills, the EPA is proposing (1) that we retain the 90-day application review process provided in the Indian Country NSR Rule; and (2) that we provide more detailed applications that are appropriate for sources in these categories that involve multiple pollutants where the reviewing authority needs to conduct a review to evaluate whether an individual source meets the requirements in the permit. However, we also recognize that a more streamlined approach may be appropriate for other source categories with few pollutants of concern and in all existing, new, and modified emission units present at the facility, must be below the major source thresholds for NSR. 18 ‘‘General Permits and Permits by Rule for the Federal Minor New Source Review Program in Indian Country,’’ U.S. Environmental Protection Agency, January 14, 2014 (79 FR 2546), https:// www.gpo.gov/fdsys/pkg/FR-2014-01-14/pdf/201330345.pdf. VerDate Mar<15>2010 17:53 Jul 16, 2014 Jkt 232001 which the operations are less complex. For graphic arts and printing operations, the EPA is proposing to change the underlying rule to provide a shorter application review period (see Section XI.) and a shorter application (see Section IX.). The permit by rule proposed as an alternative for this source category would take that streamlining a step further (see Section VII.). The remainder of this section outlines the general structure of each of the proposed general permits, and requests comment on issues that are common among the proposed general permits. Specifically, we are requesting comment on: (1) Whether the EPA’s proposed approach of incorporating by reference each reviewing authority’s approval of a request for coverage into the general permit is necessary and appropriate; and (2) The appropriateness of proposed permit terms related to the reviewing authority’s ability to reopen, revise, or terminate an individual approval of coverage under the general permit. This section also describes the general process we undertook for each of the control technology reviews required to establish the terms and conditions of each proposed general permit, and requests comment on our conclusions on several aspects of the control technology reviews. Additional information and supporting analyses on each of these proposed permits are located in the background documents. These documents are available at Docket ID No. EPA–HQ–OAR–2011–0151 and online at https://www.epa.gov/air/tribal/ tribalnsr.html. B. Structure of General Permits Each proposed general permit contains a similar overall structure. The cover page of each proposed permit contains general information on the proposed permit. First, it briefly describes the applicability of the permit to a particular source category or emissions activity the general permit regulates in accordance with 40 CFR 49.156(d)(1). This description varies for each of the proposed permits, depending on the emissions activity covered by the proposed permit. Second, the cover page limits eligibility for coverage under the permit to true minor sources. We included this limitation to allow permitting authorities the ability to process a permit application for inherently larger sources using the more extended time periods the Indian Country Minor NSR rule provides for case by case, site PO 00000 Frm 00010 Fmt 4701 Sfmt 4702 specific review. We also include this limitation in the proposed permits to remain consistent with our current policy that we will not allow sources to use general permits to create synthetic minor sources. We recognize, however, that limiting eligibility of these proposed permits to only true minor sources could limit the number and types of sources that could take advantage of the streamlined, general permitting process. In our prior proposal of January 14, 2014, we proposed to change the current policy in the Indian Country Minor NSR rule to allow general permits and permits by rule to create synthetic minor sources. Depending on the outcome of that proposal, we may amend one or more of the final permits in this proposal to allow any minor source to apply for coverage under that permit. Third, following the eligibility statement, the proposed permit directs applicants to the specific information that an applicant must include in a request for coverage under the permit in accordance with 40 CFR 49.156(d)(2)(ii) and (iii). The request for coverage serves as the permit application and some of the information in the application will differ for each proposed permit. We discuss the application and implementation tools to assist true minor sources in determining whether a source is eligible for coverage under a general permit in Section IX. Fourth, the proposed permit contains a statement that incorporates each reviewing authority’s approval of a request for coverage into the general permit. Sections 1 through 6 of the general permit, and the most current approval of the request for coverage, must be posted prominently at the facility, and each affected emissions unit and any associated air pollution control technology must be labeled with the identification number listed in the Approval of the Request for Coverage for that permitted source. We request comment on the inclusion of this condition in the permits given that the Indian Country Minor NSR rule only requires posting of the approval of coverage. As we developed the proposed permits, we envisioned situations in which the reviewing authority may need to revise information contained in the approval notice sometime after issuance. For example, a source covered by a general permit may subsequently change ownership. A reviewing authority may delegate responsibilities for the general permit to a tribal air pollution control agency. A source may subsequently need to revise something in its request for coverage that would E:\FR\FM\17JYP5.SGM 17JYP5 emcdonald on DSK67QTVN1PROD with PROPOSALS5 Federal Register / Vol. 79, No. 137 / Thursday, July 17, 2014 / Proposed Rules alter elements of the approval. For example, a source may misidentify an equipment identification number in its request for coverage, or decide to expand or limit the scope of the modification. A reviewing authority may need to alter its approval of the request for coverage for these situations. The general permit provisions at 40 CFR 51.156(b)(2) broadly reference 40 CFR 49.159, which specifically addresses the reviewing authority’s ability to reopen or administratively amend permits. The provisions, however, do not specifically delineate how they apply to an approval of a request for coverage under a general permit. By incorporating the approval into the general permit, we ensure that the revision procedures contained in 40 CFR 49.159 apply to revisions a reviewing authority may make to the approval of the request for coverage. We request comment on this approach for incorporating the approval of the request for coverage into the general permit. Alternatively, we request comment on whether such incorporation is unnecessary and on whether to apply the procedures in 40 CFR 49.159 to the approval of the request for coverage, or whether the EPA should amend the existing regulations at 40 CFR 49.156 to address amendments to the request for coverage. Fifth, the proposed permit contains information on the reviewing authority’s right to terminate or revise the general permit. The general permit provisions in the Indian Country Minor NSR rule provide the reviewing authority the ability to revise, revoke and reissue, or terminate a general permit. In harmony with those provisions, the proposed permits include authority for a reviewing authority to revise or terminate an approval of a request for coverage. We are adding these provisions to the general permit, under the authority of 40 CFR 49.156(d), to clarify how the Indian Country Minor NSR rule intended these provisions to apply to an individual request for coverage. We request comment on inclusion of these provisions in the general permit, or, alternatively, whether the EPA should amend the Indian Country Minor NSR rule to expressly delineate the reviewing authority’s right to revise or terminate an individual source’s coverage under a general permit. Finally, the proposed permit contains a statement indicating that the definitions contained in the Indian Country Minor NSR rule govern use of those terms within the general permit. The statement also refers permittees to a section of the permit that contains definitions that may be specific to the VerDate Mar<15>2010 17:53 Jul 16, 2014 Jkt 232001 source categories or emissions activities covered by the general permit; and indicates that when a term is not otherwise defined we will interpret that term consistent with normal business use. We, nonetheless, request comment on whether we should include any additional definitions to improve the clarity of the general permits. Following the general information section, each proposed permit contains the enforceable terms and conditions of the general permit. Section 1 of the Terms and Conditions provisions contains general provisions that, with only a few exceptions, are similar for all the general permits. These provisions contain statements that the Indian Country Minor NSR rule requires in each permit pursuant to 40 CFR 49.155. In each permit, the general provisions are followed by emission limitations and other operational restrictions or specifications, and monitoring, recordkeeping, and reporting requirements that are unique to each of the permits. The notice and reporting requirements are followed by a section outlining the reviewing authority’s ability to change the general permit, including the approval of the request for coverage, a section on requesting coverage under the permit, and attachments with abbreviations and acronyms, a list of definitions, and a list of reviewing authorities and areas of coverage. Attachments to the concrete batch plant and sawmill permits also contain requirements to minimize fugitive dust emissions. An attachment to the sawmill permit contains sample VOC calculations. Attachments to the graphic arts and printing operations general permit contain requirements for serious, severe or extreme ozone nonattainment areas and sample calculations for monthly VOC emissions. C. The EPA’s Control Technology Review Each permit establishes specific numerical limitations on the quantity, rate or concentration of emissions for each regulated NSR pollutant emitted by each affected emissions unit. For each general permit, in a manner similar to what a permitting authority would be expected to do for an individual source, we established these control technologybased requirements by researching both state and local air quality programs to identify control technologies or other emissions reduction measures used by similar sources in surrounding areas, and by reviewing requirements contained in existing 40 CFR parts 60 and 63 emissions standards that apply to these source categories. Some of the PO 00000 Frm 00011 Fmt 4701 Sfmt 4702 41855 proposed permits build upon the requirements in the 40 CFR parts 60 and 63 emissions standards by including some control technology measures found in state and local agencies’ general permits for these source categories. The proposed permit for graphic arts and printing operations draws control information from control technique guidelines for flexible package printing and offset lithographic printing developed by the EPA covering activities in the printing industry.19 The background documents for each proposed permit explain the state and local programs we reviewed to identify control technology options in each source category. We believe that, because these control measures are currently used by other similar sources in other areas of the country, they are technically and economically feasible, and cost effective. We request comment on this conclusion, and invite commenters to submit specific information that would indicate that either: (1) The measures in the proposed permits are not economically feasible and/or cost effective; or (2) additional economically feasible and cost effective measures are available and appropriate to include in the final general permits. In determining specific emission limitations and control measures for each permit, we considered air quality conditions in Indian country. Notably, Indian country contains both attainment and nonattainment areas for different regulated NSR pollutants.20 In some cases, for areas designated as nonattainment for a given pollutant, the proposed permits contain more stringent emission limitations for that pollutant (or precursors of that pollutant). These control requirements will help mitigate any further degradation of air quality in those areas. In other cases, however, the proposed permits do not include different emission limitations based on the attainment status of the area. In these situations, we determined that the emission limitations are sufficient to protect air quality in both attainment and nonattainment areas. For concrete batch plants, boilers, stationary spark ignition engines, stationary compression ignition engines, 19 For more information, go to: https:// www.epa.gov/glo/SIPToolkit/ctgs.html. 20 Maps for those NAAQS for which the EPA has designated nonattainment areas in Indian Country are available online at https://www.epa.gov/air/ tribal/tribalnsr.html and Docket ID No. EPA–HQ– OAR–2011–0151. NAAQS for which the EPA has designated nonattainment areas are: Ozone (2008 NAAQS), PM10 (1987 NAAQS), PM2.5 24-Hour (2006 NAAQS), and PM2.5 Annual (1997 NAAQS). There are no tribal lands in nonattainment for SO2 (2010 NAAQS), NO2, lead (2008 NAAQS), and CO. E:\FR\FM\17JYP5.SGM 17JYP5 emcdonald on DSK67QTVN1PROD with PROPOSALS5 41856 Federal Register / Vol. 79, No. 137 / Thursday, July 17, 2014 / Proposed Rules and sawmills, we also added additional provisions related to the location of the emitting activities and the source property boundary. We call these provisions, which are designed to minimize the impacts of emissions on air quality in the immediate vicinity of the source, setback requirements. Under the setback requirement, sources may not locate within a specific distance from the property boundary and nearest residences. In reviewing state and local air agency general permits, we found that permitting authorities in Alaska, Texas and Washington include setback requirements to protect local ambient air quality from potential source impacts. We find that these requirements are both reasonable and prudent measures to protect local air quality, and are economically feasible and cost effective. We, therefore, included similar measures in the proposed permits. We discuss the specific setback requirements for each category in Section VI. We welcome comments on the use of these setback requirements. We also welcome comments on the types of buildings from which we should establish setback requirements (e.g., schools, nursing homes). We further request comment on whether the setback requirement conflicts with tribal authority over zoning-related matters, and, if so, then on how we should resolve that conflict. To further protect against adverse local air quality impacts, the proposed permits ensure that no source will cause or contribute to NAAQS or PSD increment violations by prohibiting emissions that would result in such impacts. Thus, reviewing authorities will consider any air quality concerns unique to specific areas that arise after issuance of the general permits in this proposal when determining whether an individual permit applicant is eligible for coverage under the general permit. For example, if a source wants to locate in an area with air quality levels approaching or violating the NAAQS, the reviewing authority may need to request that a source apply for a sitespecific permit so that the potential for greater control than that afforded by the general permit can be evaluated. In conducting the control technology review, we also considered the anticipated growth rate of the source categories. In general, we do not anticipate significant increases in growth for these six source categories for the foreseeable future, as we identified no information indicating that VerDate Mar<15>2010 17:53 Jul 16, 2014 Jkt 232001 to be the case.21 Thus, we do not believe that emissions increases from these categories will pose unique or additional impacts on air quality in the foreseeable future that might warrant a more stringent approach to controlling emissions than contained in the proposed permits. We request comment on our conclusion about anticipated growth in these source categories and regions, and the reasonableness of the emission limitations and control measures specified in the proposed permits. D. Scope of Coverage Under Each General Permit In the Indian Country Minor NSR rule, the EPA stated that it may use the general permit mechanism to issue permits to ‘‘similar’’ types of emissions units or minor sources. This limitation on the ability to issue general permits is consistent with the EPA’s longstanding interpretation of the CAA as it relates to the ability of a permitting agency and source to use standardized protocols to meet CAA minor source permitting requirements. The proposed general permits meet the limitation that general permits apply only to similar sources, because each of the permits covers only affected emission units or emissions generating activities that are: (1) Specifically identified by name in the permit; (2) generate the same regulated NSR pollutants in the same manner and magnitude; and (3) are associated only with operations within a defined source category.22 We discuss the specific scope of each proposed general permit in more detail in Section VI. below and in the background document for each proposed general permit. E. Surrogate Annual Allowable Emission Limitations The Indian Country Minor NSR rule requires the reviewing authority to establish annual allowable emission limitations for each affected emissions unit and for each NSR regulated pollutant emitted by the unit, if the unit is issued an enforceable limitation lower than the PTE of that unit (40 CFR 49.155(a)(2)). For the six source categories in this proposal, the proposed general permits provide emissions limitations as annual tpy allowable 21 See the following memo online at https:// www.epa.gov/air/tribal/tribalnsr.html and in the docket (ID No. EPA–HQ–OAR–2011–0151): ‘‘Projected New Minor Sources in Indian Country,’’ from Lillian Grace Bradley, Environmental Economist, EPA/OAQPS to Chris Stoneman, Policy Advisor, EPA/OAQPS, March 13, 2014. 22 These criteria are not the sole manner for demonstrating that a general permit applies only to similar sources, but they serve as examples of the types of characteristics that may be relevant. PO 00000 Frm 00012 Fmt 4701 Sfmt 4702 emission limitations, throughput limits or input-based emissions limits, or some combination thereof, depending on the particular source category. In the case of concrete batch plants, we believe that a production limit serves as a reasonable surrogate for a tpy emission limitation, since there is a direct correlation between the amount of material processed and the amount of pollution emitted. We also believe that monitoring throughput rather than actual emissions may provide a more cost-effective method of demonstrating compliance. For example, concrete batch facilities regularly track a facility’s throughput, but do not necessarily analyze specific emissions discharges. Thus, reliance on throughput limits provides a more costeffective approach to regulating emissions and we believe this will enhance the potential for compliance with the proposed permit for this category. The approach for engines (spark ignition and compression ignition) and boilers also relies on a concept of ‘‘surrogate’’ emissions limitations, but instead of using throughput limits, these permits rely on ‘‘surrogate’’ capacity limits. The capacity limits are set at levels to ensure that the sources remain below certain tpy emissions rates. We also believe that setting capacity limits rather than limitations on actual emissions may provide a more costeffective and practical method of demonstrating compliance, which will enhance the potential for compliance with the proposed permit for this category. For sawmills and graphic arts and printing operations, we provide tpy emissions limitations in the permit. We require sources in these two categories to track throughput and to calculate annual emissions based on their throughput using the calculator we have provided. The reason for providing this additional flexibility for the source is due to the uncertainty they face as to the exact nature of their production at the start of a reporting period. For example, a sawmill will not necessarily know what species of wood (each with different VOC content) it will process in a given year. The source, therefore, would need to track its board-feet throughput of each wood species and calculate the emissions associated with the wood species to ensure it stays within the permitted emissions limitations. The same approach is applicable to graphic arts and printing operations that may be engaged in several different types of printing operations that involve different solvents with different VOC contents. Those sources need similar flexibility E:\FR\FM\17JYP5.SGM 17JYP5 Federal Register / Vol. 79, No. 137 / Thursday, July 17, 2014 / Proposed Rules emcdonald on DSK67QTVN1PROD with PROPOSALS5 and would also need to track solvent usage and VOC content to ensure they stay within the permitted emissions limitations. In Section VI. below, we request comment on these approaches for the six source categories. In a related matter, in the January 14, 2014, proposal, we indicated that we granted reconsideration on the issue of allowing reviewing authorities to use general permits to create synthetic minor sources and proposed to change the current policy of not allowing their use for this purpose. If the EPA allows otherwise major sources to qualify as synthetic minor sources through use of general permits, we request comment on specific changes that we would need to include in the limits of each permit to properly regulate synthetic minor sources for the six categories in this proposal. For example, should the EPA establish higher annual tpy allowable emission limitations or surrogate production limits that are just below the major source thresholds for each regulated NSR pollutant, or should the EPA maintain the limitations in the current proposed permits to maintain an adequate compliance margin? F. Requirements of the Endangered Species Act and the National Historic Preservation Act 23 The ESA requires federal agencies to ensure, in consultation with the U.S. Fish and Wildlife Service and/or the National Marine Fisheries Service (the Services), that any action they authorize, fund, or carry out will not likely jeopardize the continued existence of any listed threatened or endangered species, or destroy or adversely modify the designated critical habitat of such species. Under relevant ESA implementing regulations, federal agencies consult with the Service(s) on actions that may affect listed species or designated critical habitat. The NHPA requires federal agencies to take into account the effects of their undertakings on historic properties (i.e., properties that are either listed on, or eligible for listing on, the National Register of Historic Places) and to provide the Advisory Council on Historic Preservation (the Council) a reasonable opportunity to comment on such undertakings. Under relevant NHPA implementing regulations, NHPA consultations are generally conducted with the appropriate Tribal and/or State 23 These requirements apply to both general permits and permits by rule. Only general permits are mentioned here but the requirements apply identically to both permit types. Section VII.C. is specific to permits by rule and notes that these requirements also apply to permits by rule. VerDate Mar<15>2010 17:53 Jul 16, 2014 Jkt 232001 Historic Preservation Officers in the first instance, with opportunities for direct Council involvement in appropriate circumstances, including, for example, consultations in connection with undertakings affecting multiple tribes or states. The Indian country minor NSR program has increased the number of activities for which the EPA is the permitting authority. To meet ESA and NHPA requirements, we have developed a process for compliance with these laws when issuing the general permits. The EPA intends to consult with the Services and the Council on our general permits and the proposed procedures to address potential effects on relevant protected resources. For purposes of general permits, the EPA intends to adopt a framework that provides appropriate protection for listed species and critical habitat and historic properties. The EPA believes, based on the evaluation of available information, that the sources that are the subject of this proposal are unlikely to present a significant risk to listed species and critical habitat and to historic properties because they are by their nature small, low emitting sources. However, to ensure listed species and critical habitats and historic properties are protected, the EPA has developed a framework in the general permits that requires the applicant to identify and assess effects before a request for coverage under the general permit is submitted to the EPA. (As noted below, the applicant must submit the assessment to the EPA as part of the request for coverage.) Requiring this assessment should help identify any concerns related to potential impacts on listed species/critical habitat or historic properties early in the process when the greatest opportunities to mitigate or avoid any impacts—including changes to the facility’s location or footprint— are available. This framework is similar to procedures established by the Office of Water for the National Pollutant Discharge Elimination System General Permit for Stormwater Discharges from Construction Activities.24 The EPA believes that requiring a process in the general air quality permits that is similar to the already-established process for the general stormwater permits will be beneficial for all 24 ‘‘Final National Pollutant Discharge Elimination System (NPDES) General Permit for Stormwater Discharges from Construction Activities,’’ U.S. Environmental Protection Agency, February 29, 2012 (77 FR 12286), https:// www.gpo.gov/fdsys/granule/FR-2012-02-29/20124822/content-detail.html. PO 00000 Frm 00013 Fmt 4701 Sfmt 4702 41857 concerned: The applicants, the EPA, the tribes, and the Services. The screening processes developed in the permits for both the ESA and NHPA require the applicant to develop information about the possible effects of the proposed new or modified facility, which includes appropriate outreach to relevant expert resource agencies. Such information and a certification regarding the outcome of the applicant’s screening procedures are submitted to the EPA as part of the request for coverage under the general permit. This information is included as an appendix to the applications for requests for coverage under the general permits. The EPA will review this information as part of determining whether a source is eligible for coverage under the general permit. Because we have limited the applicability of the general permits to categories of sources that have low emissions, we do not expect they are likely to adversely affect listed species/ critical habitats, nor should they have potential effects on historic properties. However, if, through the procedures required in the permit, a source is determined to have an adverse effect on listed species/critical habitats or potential effects on historic properties, the EPA retains the authority to deny coverage under the general permit and to proceed with source-specific permitting and consultation with the appropriate resource agency(ies). VI. Summary of Specific Terms and Conditions of the General Permits and Request for Comment In the following sections, we provide a brief summary of the source category regulated by each general permit and the areas of each proposed general permit on which we specifically seek public comment. In this preamble, we are not delineating every aspect of the requirements of the general permits. Instead, we refer readers to the proposed permits and associated background information to review all of the detailed requirements we include in each general permit. Although we are soliciting comments on specific aspects of the proposed permits, we, nonetheless, invite the public to comment on all relevant aspects of the proposed permits. Generally, we have designed the proposed permits to be as comprehensive as possible and, thus, they contain emission limitations requirements for several, potentially affected emission units that could be found at a source. If a source determines that it does not have all of the emission units that the general permit covers, it can still seek coverage for those units E:\FR\FM\17JYP5.SGM 17JYP5 41858 Federal Register / Vol. 79, No. 137 / Thursday, July 17, 2014 / Proposed Rules the permit covers. The intent of the comprehensive permit is to help avoid sources with multiple emission units having to apply for multiple general permits. In any case, if a source determines that it is does not meet the qualifications of the general permit for a given category, then it can apply for a site-specific permit. We are proposing the general permits for true minor sources in Indian country. To be eligible for a general permit as proposed in this action, a source would need to calculate the PTE for all of its NSR-regulated pollutants for all existing, new, and modified emission units. If the total PTE is less than the NSR major source thresholds, then the source is eligible for the permit, provided all other qualifying conditions are satisfied. emcdonald on DSK67QTVN1PROD with PROPOSALS5 A. Concrete Batch Plants 1. What is a concrete batch plant? A concrete batch plant is an operation that combines various ingredients to form concrete. Some of these inputs include sand, water, aggregate (rocks, gravel, etc.), fly ash, potash, and cement. There are two types of concrete batch plants: Ready mix plants and central mix plants. A concrete plant can have a variety of parts and equipment, including but not limited to: Mixers (either tilt-up or horizontal or in some cases both), cement batchers, aggregate batchers, conveyors, radial stackers, aggregate bins, cement bins, heaters, chillers, cement silos, batch plant controls, and dust collectors (to minimize environmental pollution). Concrete is composed essentially of water, cement, sand (fine aggregate) and coarse aggregate. Approximately 75 percent of the U.S. concrete manufactured is produced at plants that store, convey, measure and discharge these constituents into trucks for transport to a job site. At most of these plants, sand, aggregate, cement and water are all gravity fed from the weight hopper into the mixer trucks. The concrete is mixed on the way to the site where the concrete is to be poured. At some of these plants, the concrete may also be manufactured in a central mix drum and transferred to a transport truck. Most of the remaining concrete manufactured is cast as products in a factory setting. Precast products range from concrete bricks and paving stones to bridge girders, structural components, and panels for cladding. Concrete masonry, another type of manufactured concrete, may be best known for its conventional 8 x 8 x 16-inch block. In a few cases concrete is dry batched or prepared at a building construction site. VerDate Mar<15>2010 17:53 Jul 16, 2014 Jkt 232001 This proposed general permit would apply to the construction of new true minor source concrete batch plants or the modification of existing true minor concrete batch plants located in Indian country. The proposed permit is designed to be as comprehensive as possible and, thus, contains emission limitations requirements for: • Storage silos; • Batch drop points; • Loading transfer areas; • Weigh hoppers; • Auxiliary storage bins; • Non-emergency stationary engines; • Emergency stationary engines; and • Setbacks. The proposed permit requires that the permittee maintain and operate each affected emission unit and any associated air pollution control equipment, considering the manufacturer’s recommended operating procedures, so as to minimize emissions of NSR regulated pollutants. The reviewing authority will determine whether the permittee is using acceptable operating and maintenance procedures based on monitoring results, opacity observations, review of operating and maintenance procedures, and inspection of the permitted source. (Failure to meet these requirements would constitute a violation of the permit.) The proposed permit requires each storage silo to be equipped with an audible alarm or an automatic shutoff system that warns when the silo is full. Loading operations cannot be conducted without a warning or shutoff device. Storage silos, weigh hoppers and auxiliary storage bins must be vented to a fabric or cartridge filter. The filter systems can be a centralized system. A suction shroud or other pickup device should be installed at each batch drop point (drum, truck loading etc.) and vented to a fabric or cartridge filter system. Loading and unloading areas must be well lit during non-daylight hours when the permitted source is in operation and visible emissions from each storage silo, weigh hopper and auxiliary storage bin must not exceed 10 percent opacity based on a six-minute average (according to EPA Method 9 26). For portable and permanent concrete batch plants, the limit on production is a maximum annual production rate of 2,000,000 cubic yards. The proposed permit also requires a fugitive dust control plan. The proposed permit contains requirements for non-emergency and emergency engines, in the event such engines are present at the concrete batch plant. Non-emergency compression ignition engines present at the site, excluding nonroad mobile engines, must comply with the following: • Use diesel or biodiesel containing no more than 15 ppm (0.0015 percent) sulfur; • Each compression ignition engine that commenced construction on or after June 12, 2006 must be certified to the applicable Tier standards in 40 CFR 89.112 and 40 CFR 1039.101 through 1039.104, for all pollutants, for the same 25 AP–42, Chapters 11.19.12, Concrete Batching, https://www.epa.gov/ttn/chief/ap42/ch11/ index.html. 26 Method 9—Visual Determination of the Opacity of Emissions From Stationary Sources, https://www.epa.gov/ttn/emc/promgate/m-09.pdf. Raw materials for concrete batch operations can be delivered to a plant by rail, truck or barge. The cement is transferred to elevated storage silos pneumatically or by bucket elevator. The sand and coarse aggregate are transferred to elevated bins by front end loader, clamshell crane, belt conveyor, or bucket elevator. From these elevated bins, the constituents are fed by gravity or screw conveyor to weigh hoppers, which combine the proper amounts of each material. PM, consisting primarily of cement and pozzolan dust, but including some aggregate and sand dust emissions, is the primary pollutant of concern. In addition, there are emissions of metals that are associated with this PM. All but one of the emission points is fugitive in nature. The only point sources are the transfer of cement and pozzolan material to silos, and these are usually vented to a fabric filter or ‘‘sock.’’ Fugitive sources include the transfer of sand and aggregate, truck loading, mixer loading, vehicle traffic, and wind erosion from sand and aggregate storage piles. The amount of fugitive emissions generated during the transfer of sand and aggregate depends primarily on the surface moisture content of these materials. The extent of fugitive emissions control varies widely from plant to plant. Types of controls used may include water sprays, enclosures, hoods, curtains, shrouds, movable and telescoping chutes, central duct collection systems, and the like. A major source of potential emissions, the movement of heavy trucks over unpaved or dusty surfaces in and around the plant, can be controlled by good maintenance and wetting of road surfaces.25 2. What is in the proposed general air quality permit for new or modified true minor source concrete batch plants? PO 00000 Frm 00014 Fmt 4701 Sfmt 4702 E:\FR\FM\17JYP5.SGM 17JYP5 Federal Register / Vol. 79, No. 137 / Thursday, July 17, 2014 / Proposed Rules emcdonald on DSK67QTVN1PROD with PROPOSALS5 model year and maximum engine power; and • Each compression ignition engine that commenced construction before June 12, 2006 shall meet certain standards as laid out in the permit based on the engine’s maximum rated power. If the source includes one or more emergency engines, each emergency engine must be equipped with a nonresettable hour meter and, if using fuel oil, then it must use diesel or biodiesel containing no more than 15 ppm (0.0015 percent) sulfur. Newer emergency engines—model year 2006 or later for compression ignition engines and 2009 or later for spark ignition engines—must meet certain certification or emission requirements that are contained in the EPA emissions standards at 40 CFR part 89, 40 CFR part 90, 40 CFR part 1048 or Table 1 to 40 CFR part 60, subpart JJJJ, as applicable. Other, older emergency engines are required to meet certain routine maintenance requirements, and must follow the manufacturer’s emissionrelated operation and maintenance instructions or the permittee must develop a maintenance plan, which must provide, to the extent practicable, for the maintenance and operation of the engine in a manner consistent with good air pollution control practice for minimizing emissions. The proposed general permit includes monitoring that is sufficient to ensure compliance with the emission limitations that apply to the source, including ensuring the fabric/cartridge filters are operating properly, taking weekly opacity observations and fugitive emissions surveys and meeting certain other requirements. The permit also requires performance testing for emergency engines present at the plant that must meet certain emissions standards, but are not certified by the manufacturer to those standards and are not required to be certified by the manufacturer. This requirement is needed since the EPA certification program for certain engines is voluntary. The proposed general permit includes recordkeeping and reporting sufficient to ensure compliance with the monitoring requirements. 3. Request for Comment on the Proposed General Air Quality Permit for New or Modified True Minor Source Concrete Batch Plants We request comment on all aspects of the general permit for concrete batch plants. We specifically request comment in the following three areas: VerDate Mar<15>2010 17:53 Jul 16, 2014 Jkt 232001 a. Throughput Production Limit as a Surrogate for Annual Tons Per Year Allowable Emission Limitations The proposed concrete batch plant general permit contains a throughputbased production limit that serves as a surrogate for annual tpy allowable emission limitations. We discuss the use of surrogate limits in Section V.E. above. For portable and permanent concrete batch plants, as stated above, the limit on production is a maximum annual production rate of 2,000,000 cubic yards. The background information document for the proposed permit contains the approximate tpy emission thresholds for which the throughput limits act as surrogates. The proposed permit does not establish different throughput limits based on the attainment status of the area. We request comment on our use of throughput limits as a surrogate for tpy emission limitations for this source category, and on whether there should be different production throughput limits in attainment and nonattainment areas. In establishing specific limits for concrete batch facilities, we considered whether we should compute the production throughput limits on a tpy basis, or over a shorter period of time to ensure continuous compliance. For concrete batch plants, where PM10 is the limiting pollutant for non-fugitive emissions, we elected an annual production limit to ensure annual compliance. We request comment on whether we should instead establish a monthly total emission limitation based on a 30-day rolling total or on any other appropriate averaging period. b. Setback Requirement The proposed general permit requires concrete batch plants to locate at least 150 feet from the nearest property boundary and 1,000 feet from the nearest residence. A number of states include setback requirements in their general permits for this source category.27 We believe that this requirement will minimize the impact of emissions from these sources on localized air quality. We request comment on whether we should include the setback requirement in the final permit to provide additional protection against adverse impacts to localized air quality. In addition, we request comment on whether there are other 27 Information on state setback provisions is available at: Background Document: General Air Quality Permit for New or Modified True Minor Source Concrete Batch Plants, Docket ID No. EPA– HQ–OAR–2011–0151, https://www.epa.gov/air/ tribal/tribalnsr.html.

Authorizing Multiple Locations Concrete batch plants can operate as portable stationary sources. A plant will locate in a single area for a specified period of time and then disassemble and relocate to another area. We structured the proposed general permit to accommodate relocation of a plant. A source may identify multiple sites of operation in its request for coverage. The reviewing authority will consider the request for each location, and will specify approval of one or more of these locations in the approval of the request for coverage. If the reviewing authority does not approve a specific location, then the source will need to reapply for coverage under the general permit or for a site specific permit before relocating to this site. The general permit also requires a source to submit a notification to the reviewing authority each time it relocates to a pre-approved site. We request comment on the use of the general permit to authorize relocation of a plant to pre-approved site locations. B. Boilers 1. What is a boiler? A boiler is a device in which water typically is heated to provide steam to drive turbines or engines, supply heat, or process materials. This proposed permit covers steam generating units located at institutional, commercial, and industrial facilities which combust nonsolid fossil fuels such as natural gas and fuel oil. This permit does not cover boilers located at electric utilities or boilers used for the burning of other fuels such as coal and wood. This source category does not cover the manufacturers of boilers. The proposed General Air Quality Permit for New or Modified True Minor Source Boilers only covers new, true minor source boilers and modifications of existing true minor source boilers. Boilers designed to burn fuel oil primarily combust distillate oils and residual oils.28 These boilers can be of water tube, fire tube, cast iron, or tubeless design. Water tube boilers are used in a variety of applications ranging from supplying large amounts of process steam to providing space heat for 28 AP–42, Chapter 1.3—Fuel Oil Combustion, https://www.epa.gov/ttnchie1/ap42/ch01/. E:\FR\FM\17JYP5.SGM 17JYP5 emcdonald on DSK67QTVN1PROD with PROPOSALS5 41860 Federal Register / Vol. 79, No. 137 / Thursday, July 17, 2014 / Proposed Rules industrial facilities. In a water tube boiler, combustion heat is transferred to water flowing through tubes which line the furnace walls and boiler passes. The tube surfaces in the furnace (which houses the burner flame) absorb heat primarily by radiation from the flames. The tube surfaces in the boiler (adjacent to the primary furnace) absorb heat primarily by convective heat transfer. Fire tube boilers are used primarily for heating systems, industrial process steam generators, and portable power boilers. In fire tube boilers, the hot combustion gases flow through the tubes while the water being heated circulates outside of the tubes. A cast iron boiler is one in which combustion gases rise through a vertical heat exchanger and out through an exhaust duct. Water in the heat exchanger tubes is heated as it moves upward through the tubes. Cast iron boilers produce low pressure steam or hot water, and generally burn oil or natural gas. They are used primarily in the residential and commercial sectors. (Note that residential boilers are not covered by the proposal.) Tubeless boilers incorporate nested pressure vessels with water in between the shells. Combustion gases are fired into the inner pressure vessel and are then sometimes recirculated outside the second vessel. Natural gas combustion boilers are used to generate industrial electric power, produce industrial process steam and heat, and heat residential and commercial space.29 (Note that residential boilers are not covered by the proposal.) Natural gas is generally more than 85 percent methane with varying amounts of ethane, propane, butane, and inert gases (typically nitrogen, carbon dioxide (CO2), and helium). Natural gas combustion boilers may be of water tube, fire tube, or cast iron design. Water tube boilers can be distinguished either as field erected units or packaged units; the former are built onsite in either wall-fired or tangential-fired configurations and generally have heat input levels exceeding 100 million British thermal units (MMBtu)/hour, while the latter are shipped where needed, are always wallfired, and generally have heat input levels of less than 100 MMBtu/hour. The emissions from fuel oil-fired boilers include PM, SO2, NOX, CO, small amounts of VOCs, and trace elements. The emissions from natural gas-fired boilers include NOX, CO, CO2, nitrous oxide, VOCs, trace amounts of SO2, and PM. 29 AP–42, Chapter 1.4—Natural Gas Combustion, https://www.epa.gov/ttnchie1/ap42/ch01/. VerDate Mar<15>2010 17:53 Jul 16, 2014 Jkt 232001 2. What is in the proposed General Air Quality Permit for New or Modified True Minor Source Boilers? This proposed general permit would apply in Indian country to the construction of new, true minor source boilers and modifications of existing true minor source boilers. The proposed permit is designed to be as comprehensive as possible and, thus, contains requirements for: • Boiler capacity limits; • Emissions and opacity limitations; • Boiler stacks; • Fuel usage; • Setbacks; and • Emergency engines. The proposed permit requires that the permittee maintain and operate each affected emission unit and any associated air pollution control equipment, considering the manufacturer’s recommended operating procedures, so as to minimize emissions of NSR regulated pollutants. The reviewing authority will determine whether the permittee is using acceptable operating and maintenance procedures based on monitoring results, opacity observations, review of operating and maintenance procedures, and inspection of the permitted source. (Failure to meet these requirements would constitute a violation of the permit.) The proposed permit uses boiler capacity limits as emissions limitations. The permit provides a capacity limit for an individual boiler located in an attainment or nonattainment area of less than 100 MMBtu/hour. Further, the proposed permit restricts capacity by laying out a matrix of combined maximum rating capacity limits for different fuel types (i.e., liquid, gaseous) by boiler size or type. The combined capacity limits vary by area designation/ classification. The combined capacity limits are set at levels intended to ensure the covered sources remain below major source levels. The proposed permit also provides output-based and input-based emission limitations for boilers rated at 10 MMBtu/hour or greater. The proposed permit restricts fuel use to natural gas or fuel oil (i.e., diesel or biodiesel) with a sulfur content of 0.0015 percent or less by weight. In addition, a natural gas unit may use fuel oil as a backup emergency fuel for up to 500 hours per calendar year. The proposed permit requires that the boiler(s) must not discharge into the atmosphere any gases that exhibit 5 percent opacity or greater averaged over any six-consecutive-minute period. The boiler stack(s) must be above the PO 00000 Frm 00016 Fmt 4701 Sfmt 4702 buildings in the vicinity, discharge vertically, and have no obstructions to gas flow such as rain caps, except for hinged rain caps. Each boiler must undergo biennial tune-ups. If the permittee is operating the boiler(s) in a severe or extreme ozone nonattainment area, then the permittee must comply with additional requirements. Boilers located in severe or extreme ozone nonattainment areas must meet tighter emissions limitations for NOX. The proposed permit contains requirements for emergency engines located at the same facility as a boiler. Each emergency engine must be equipped with a non-resettable hour meter and, if using fuel oil, then it must use diesel or biodiesel containing no more than 15 ppm (0.0015 percent) sulfur by weight. Newer emergency engines—model year 2006 or later for compression ignition engines and 2009 or later for spark ignition engines—must meet certain certification or emission requirements that are specified in the EPA emissions standards at 40 CFR part 89, 40 CFR part 90 and 40 CFR part 1048 or Table 1 to 40 CFR part 60, subpart JJJJ, as applicable. Older emergency engines are required to meet certain routine maintenance requirements, and must follow the manufacturer’s emission-related operation and maintenance instructions or the permittee must develop a maintenance plan, which must provide, to the extent practicable, for the maintenance and operation of the engine in a manner consistent with good air pollution control practice for minimizing emissions. The proposed permit includes monitoring that is sufficient to ensure compliance with the emission limitations that apply to the source, including visible emissions surveys and an initial and additional periodic performance testing. The proposed permit also requires performance testing for emergency engines located at the same source that must meet certain emissions standards, but are neither required to be certified by the manufacturer nor are certified by the manufacturer as meeting those standards. The basis for this requirement is the fact that the EPA certification program for certain engines is voluntary. The proposed permit includes recordkeeping and reporting sufficient to ensure compliance with the monitoring requirements.

Request for Comment on the Proposed General Air Quality Permit for New or Modified True Minor Source Boilers We request comment on all aspects of the general permit for boilers. We specifically request comment in the following three areas: a. Surrogate Annual Allowable Emission Limitations The boilers general permit contains capacity limits that serve as surrogate annual tpy allowable emission limitations. We discuss the use of surrogate limits in detail in Section V.E. above. In addition, we request comment on the use of these surrogate capacity limits. In lieu of establishing surrogate limits, we request comment on whether, instead of containing surrogate limits, the final permits should contain tpy emission limitations and require the use of monitoring of material use to demonstrate compliance. We also request comment on finalizing two boiler general permits—one intended for smaller, simpler sources that uses capacity limits and one for larger, more complex sources that uses tpy emission limitations together with additional monitoring and recordkeeping requirements. Other requirements in the permits would be essentially the same. Finally, we request comment on the appropriateness of establishing different capacity limits based on the attainment status of the area and whether the specified capacity limits should be lower in nonattainment areas than attainment areas. emcdonald on DSK67QTVN1PROD with PROPOSALS5 b. Should we establish different requirements for severe or extreme ozone nonattainment areas? The proposed general permit contains emissions limits for sources that locate in severe or extreme ozone nonattainment areas. We request comment on the need for these limits. c. Setback Requirement The proposed general permit requires the exhaust from each boiler or heater to be located a minimum of 50 feet from the nearest property line and 150 feet from any adjacent residential or commercial establishment or place of public assembly. The EPA’s 40 CFR parts 60, 61, and 63 regulations do not contain setback requirements affecting boilers or heaters. However, certain states include setback requirements in their general permits for certain source categories, although not necessarily for boilers. We believe that these requirements will minimize the impact of emissions from these sources on localized air quality. These setbacks are VerDate Mar<15>2010 17:53 Jul 16, 2014 Jkt 232001 less stringent than the proposed setback permit provisions in the proposed concrete batch plant, engine and sawmill permits. We believe a different (lesser) setback requirement is warranted for the boilers general permit compared to the other general permits because of the different type of equipment associated with the stationary sources covered by this proposed permit. This proposed permit would generally be used for institutional, commercial, and small industrial operations which tend to have less air impact. In addition, the boilers general permit contains specific numerical limits on NOX and CO emissions that will further limit air impacts. We request comment on whether we should include these setback requirements in the final permit to provide additional protection against adverse impacts to local air quality. In addition, we request comment on whether there are other neighboring types of buildings from which the setback should apply (e.g., schools, nursing homes) and whether to require owners/operators of the boilers subject to the permit to use physical markers on their property to show compliance with the setback requirements. C. Stationary Compression Ignition and Spark Ignition Engines 1. What are compression ignition and spark ignition engines? Engines covered by these proposed general permits 30 are stationary internal combustion engines (ICE or engine) that convert heat energy into mechanical work and are not mobile. This source category does not include combustion turbines or nonroad 31 engines (mobile ICE) such as those on forklifts, offhighway mobile cranes, bulldozers, and lawnmowers. Stationary ICE include reciprocating ICE, rotary ICE, and other ICE, except combustion turbines as noted above. Engine manufacturers are not included in this source category. In addition, these general permits only apply to engines located at true minor sources. The proposed general permits cover both stationary non-emergency and emergency stationary ICE. Emergency stationary ICE include any stationary internal combustion engine whose operation is limited to emergency 30 The EPA is making available for comment two proposed general permits: One for spark ignition internal combustion engines and one for compression ignition internal combustion engines. 31 As defined in 40 CFR 1068.30, a nonroad engine is used to propel a motor vehicle, aircraft, or a vehicle used solely for competition. PO 00000 Frm 00017 Fmt 4701 Sfmt 4702 41861 situations and for which testing and maintenance are required. Examples include stationary ICE used to produce power for critical networks or equipment (including power supplied to portions of a facility) when electric power from the local utility (or the normal power source, if the facility runs on its own power production) is interrupted, or stationary ICE used to pump water in the case of fire, flood, or other adverse event. Stationary ICE used to supply power to an electric grid or that supply power as part of a financial arrangement with another entity are not considered to be emergency engines.32 There are two types of ICE: Spark ignition and compression ignition. A spark ignition engine is a gasoline, natural gas, or any other type of engine with a spark plug (or other sparking device) and with operating characteristics significantly similar to the theoretical Otto combustion cycle. Spark ignition engines usually use a throttle to regulate intake air flow to control power during normal operation. Dual-fuel engines in which a liquid fuel (typically diesel fuel) is used for compression ignition ICE and a gaseous fuel (typically natural gas) is used as the primary fuel at an annual average ratio of less than 2 parts diesel fuel to 100 parts total fuel on an energy equivalent basis are spark ignition engines. A compression ignition ICE is defined as an engine that is not a spark ignition engine. These engines are typically diesel engines where the heat generated from compression is enough to initiate the combustion process, without needing an external spark.33 Gasoline, diesel (No. 2 fuel oil), and natural gas are the three primary fuels used for ICE. Most natural gas-fired reciprocating engines are used in the natural gas industry at pipeline compressor and storage stations and at gas processing plants.34 Gasoline and small diesel ICE (with capacities equal to or less than 600 horsepower (hp)) are used in a wide variety of industrial applications such as generators, pumps, and material handling equipment (such as conveyors). Gasoline is used primarily for mobile and portable engines. Diesel fuel oil is the most versatile fuel and is used in compression ignition engines of all 32 The definitions for emergency and stationary engines are adopted from the definitions in 40 CFR 60.4219. 33 The definitions for spark ignition and compression ignition engines are adopted from the definitions in 40 CFR 60.4219. 34 AP–42, Chapter 3.2—Natural Gas-fired Reciprocating Engines, https://www.epa.gov/ ttnchie1/ap42/ch03/.

Substantial differences in engine duty cycles exist.35 Large stationary diesel ICE (with capacities greater than 600 hp) are often used in oil and gas exploration and production. These engines, in groups of 3 to 5, supply mechanical power to operate drilling (rotary table), mud pumping, and hoisting equipment, and may also operate pumps or auxiliary power generators. Another frequent application of large stationary diesel ICE is electricity generation for both base and standby service. Smaller uses include irrigation, hoisting, and nuclear power plant emergency cooling water pump operation.36 The primary criteria pollutants emitted by engines are NOX, CO, and VOC. The formation of NOX is exponentially related to combustion temperature in the engine cylinder. The other pollutants, CO and VOC, are primarily the result of incomplete combustion. PM emissions include trace amounts of metals, non-combustible inorganic material, and condensible, semi-volatile organics which result from volatized lubricating oil, engine wear, or from products of incomplete combustion. Emissions of sulfur compounds, mainly SO2, are directly related to the sulfur content of the fuel. Three generic control techniques have been developed for reciprocating engines: Parametric controls (timing and operating at a leaner air-to-fuel ratio); combustion modifications such as advanced engine design for new sources or major modification to existing sources (clean-burn cylinder head designs and pre-stratified charge combustion for rich-burn engines); and post-combustion catalytic controls installed on the engine exhaust system. Post-combustion catalytic technologies include selective catalytic reduction, nonselective catalytic reduction, and CO oxidation catalysts.37 2. What is in the proposed General Air Quality Permits for New or Modified True Minor Source Spark Ignition and Compression Ignition Engines? These two proposed general permits would apply to the construction of new, true minor source stationary compression ignition and spark ignition engines or the modification of existing, true minor source engines located in 35 AP–42, Chapter 3.3—Gasoline and Diesel Industrial Engines, https://www.epa.gov/ttnchie1/ ap42/ch03/. 36 AP–42, Chapter 3.4—Large Stationary Diesel and All Stationary Dual-fuel Engines, https:// www.epa.gov/ttnchie1/ap42/ch03/. 37 AP–42, Chapter 3.2—Natural Gas-fired Reciprocating Engines, https://www.epa.gov/ ttnchie1/ap42/ch03/. VerDate Mar<15>2010 17:53 Jul 16, 2014 Jkt 232001 Indian country. We created separate proposed general permits, one for compression ignition engines and one for spark ignition engines, because there are different requirements for each type of engine. Both engine general permits cover emergency and non-emergency engines. (Sources that only have emergency engines and also intend to construct a boiler may want to consider the boiler general permit, which allows for greater boiler and emergency engine capacity.) However, we have written both proposed general permits to accommodate emergency engines of both engine types because the emissions from emergency engines are relatively small and we did not want a particular source to not be able to qualify for the general permit if, for example, they happen to have a small compression ignition emergency engine at a source of non-emergency spark ignition engines. As a result, the spark ignition engine general permit covers non-emergency spark ignition engines, emergency spark ignition engines, and emergency compression ignition engines. The compression ignition general permit covers non-emergency compression ignition engines, emergency compression ignition engines, and emergency spark ignition engines. The proposed general permits for compression ignition and spark ignition engines require that the permittee, considering the manufacturer’s recommended operating procedures, maintain and operate each affected emission unit and any associated air pollution control equipment so as to minimize emissions of NSR regulated pollutants. The reviewing authority will determine whether the permittee is using acceptable operating and maintenance procedures based on monitoring results, opacity observations, review of operating and maintenance procedures, and inspection of the permitted source. (Failure to meet these requirements would constitute a violation of the permit.) The proposed compression ignition general permit imposes different requirements depending upon where the source chooses to locate or modify and whether the engine is for emergency or non-emergency purposes. The proposed permit contains a setback requirement. Each non-emergency compression ignition engine must not be located less than 150 feet from the nearest property boundary and 1,000 feet from the nearest residence. The proposed compression ignition general permit contains two options for meeting capacity limits for engines locating in ozone attainment, unclassifiable or attainment/ PO 00000 Frm 00018 Fmt 4701 Sfmt 4702 unclassifiable areas or ozone marginal and moderate nonattainment areas. Option 1 allows for a source to have greater non-emergency engine capacity (up to 3800 hp) if the non-emergency engines are within a set of certain parameters, mainly related to whether the engines are part of a generator set. These types of engines must meet much more stringent emission limits, resulting in fewer emissions, and, thus, the permit provides the ability to increase the capacity limit. Option 2 allows for less capacity for non-emergency engines (1900 hp) but does not require nonemergency engines to be within the specific parameters in Option 1. The proposed permit also contains an additional overall capacity limit for engines locating or modifying in serious ozone nonattainment areas (1100 hp for non-emergency engines and 750 hp for emergency engines) and does not allow permit coverage for engines locating or modifying in severe or extreme ozone nonattainment areas. The capacity limits restrict the size of engines that would be covered by the proposed general permit. The proposed capacity limits serve as surrogate emissions limitations and are set at levels that correspond to emission rates intended to ensure emissions from sources covered by the general permit are below major source levels. The proposed compression ignition permit also includes requirements for auxiliary heaters present at the new or modified facility so that the permittee would not need to seek a separate permit for that emissions unit. For the auxiliary heaters, the permit provides capacity limits which require that the combined maximum heat input of all auxiliary heaters not be greater than 10 MMBtu/hour and they can only burn natural gas. Non-emergency compression ignition engines can only use distillate fuel (i.e., diesel or biodiesel) containing no more than 15 ppm (0.0015 percent) sulfur by weight. Each of the engines must be model year 2014 or later and certified by the manufacturer to the applicable standards in 40 CFR part 89 and the Tier 4 standards in 40 CFR 1039.101 through 1039.104, for all pollutants, for the same model year and maximum engine power. Under the proposed spark ignition general permit, spark ignition engines must meet certain capacity limits intended to ensure the sources operate as minor sources. The combined maximum engine power of all nonemergency spark ignition engines at a single permitted source location shall be no greater than 1750 hp. The combined maximum engine power of all E:\FR\FM\17JYP5.SGM 17JYP5 emcdonald on DSK67QTVN1PROD with PROPOSALS5 Federal Register / Vol. 79, No. 137 / Thursday, July 17, 2014 / Proposed Rules emergency engines at a single permitted source location must be no greater than 800 hp. Non-emergency spark ignition engines must comply with the limitations and standards in 40 CFR part 1054, 40 CFR part 1048, or Table 1 to 40 CFR part 60, subpart JJJJ, as applicable. The Permittee must operate and maintain each engine certified by the manufacturer, and any associated control device, according to the manufacturer’s emission-related written instructions. Each natural gas-fired engine may be operated using propane for a maximum of 100 hours per year as an alternative fuel solely during emergency operations, provided such records are kept. The proposed spark ignition general permit also contains a setback requirement. Each non-emergency spark ignition engine must not be located less than 150 feet from the nearest property boundary and 1,000 feet from the nearest residence. The proposed compression ignition and spark ignition permits contain requirements for emergency engines located at the same source as the boiler(s), in the event such engines are present at the same facility as the boiler(s). Each emergency engine must be equipped with a non-resettable hour meter and, if using fuel oil, then it must use diesel or biodiesel containing no more than 15 ppm (0.0015 percent) sulfur by weight. Newer emergency engines—model year 2006 or later for compression ignition engines and 2009 or later for spark ignition engines—must meet certain certification or emission requirements that are specified in the EPA emissions standards at 40 CFR part 89, 40 CFR part 90 and 40 CFR part 1048 or Table 1 to 40 CFR part 60, subpart JJJJ, as applicable. Older emergency engines are required to meet certain routine maintenance requirements, and must follow the manufacturer’s emission-related operation and maintenance instructions or the permittee must develop a maintenance plan, which must provide, to the extent practicable, for the maintenance and operation of the engine in a manner consistent with good air pollution control practice for minimizing emissions. The proposed compression ignition and spark ignition permits include monitoring that is sufficient to ensure compliance with the emission limitations that apply to the covered ICE, including requirements to monitor fuel use on a monthly basis for each engine and to conduct performance tests for engines not certified by the manufacturer. The proposed permits also require performance testing for VerDate Mar<15>2010 17:53 Jul 16, 2014 Jkt 232001 spark ignition emergency engines that must meet certain emissions standards, but are neither required to be certified by the manufacturer nor certified by the manufacturer to those standards and are not required to be certified by the manufacturer. This requirement is necessary because the EPA certification program for certain engines is voluntary. The proposed spark ignition general permit also includes, for each engine equipped with an air-to-fuel ratio controller, a requirement for proper maintenance and operation of the engine and emissions control device to ensure its smooth operation. The proposed permits include recordkeeping and reporting requirements. 3. Request for Comment on the Proposed General Air Quality Permits for New or Modified True Minor Source Spark Ignition and Compression Ignition Engines We request comment on all aspects of the proposed general permits for engines. We specifically request comment in the following four areas: (a) The Use of Capacity Limits as Surrogate Annual Allowable Emission Limitations In addition to fuel sulfur content limits and output-based limitations for auxiliary heaters, the EPA is proposing to use capacity limits as surrogate annual allowable emission limitations for the engines source category. The capacity limits are set at levels intended to ensure that the engines operate as minor sources.38 We request comment on the appropriateness of these capacity limits. We also request comment on whether the required emissions limitations should be expressed as capacity limits or in another form. (b) Setback Requirement The proposed general permits require stationary spark ignition and compression ignition engines to locate at least 150 feet from the nearest property boundary and 1,000 feet from the nearest residence. The EPA’s 40 CFR parts 60, 61, and 63 regulations do not contain setback requirements affecting these engines. However, certain states include setback requirements in their general permits for certain source categories, but not necessarily for engines alone. We believe that it is prudent to propose a setback for engines 38 Information on the source of these capacity limits is available at: Background Document: General Air Quality Permits for New or Modified True Minor Source Compression Ignition and Spark Ignition Engines, Docket ID No. EPA–HQ–OAR– 2011–0151, https://www.epa.gov/air/tribal/ tribalnsr.html. PO 00000 Frm 00019 Fmt 4701 Sfmt 4702 41863 due to the potential for local scale air quality impacts due to NOX emissions from compression ignition engines that can transform in the atmosphere to nitrogen dioxide (NO2) and have local NO2 impacts, as well as CO emissions from spark ignition engines that can have local CO impacts. We believe that these requirements will minimize the impact of emissions from these sources on localized air quality. We request comment on whether we should include these setback requirements in the final permits to provide additional protection against adverse impacts to local air quality. In addition, we request comment on whether there are other neighboring types of buildings from which the setback should apply (e.g., schools, nursing homes) and whether to require owners/operators of the engines subject to the permit to use physical markers on their property to show compliance with the setback requirements. (c) Should we establish different requirements for compression ignition engines locating or modifying in serious ozone nonattainment areas? The proposed general permit for compression ignition engines contains additional requirements for sources that locate or modify in serious ozone nonattainment areas. These requirements consist of overall capacity limits for non-emergency and emergency engines. We added this requirement to provide extra air quality protection for areas with poorer ozone air quality. We request comment on the need for these enhanced requirements in serious ozone nonattainment areas. (d) Should owners and operators seeking to locate compression ignition engines in severe, and/or extreme ozone nonattainment areas (or to modify engines already located in those areas) be allowed to use the proposed general permit? The proposed compression ignition general permit contains requirements for engines locating or modifying in marginal, moderate and serious ozone nonattainment areas. Engines locating or modifying in severe or extreme ozone nonattainment areas are not eligible for coverage under the proposed general permit. This is because the appropriate capacity limits that EPA would set in order to keep an engine from being a major NOX source in a severe or extreme nonattainment would be too low to be viable. We request comment on whether our reasoning here is sound and whether we should restrict applicability of the proposed compression ignition engine general permit to marginal, E:\FR\FM\17JYP5.SGM 17JYP5 41864 Federal Register / Vol. 79, No. 137 / Thursday, July 17, 2014 / Proposed Rules moderate, and serious ozone nonattainment areas. D. Graphic Arts and Printing Operations emcdonald on DSK67QTVN1PROD with PROPOSALS5 1. What is a graphic arts and printing operation? The term ‘‘graphic arts’’ as used here means four basic processes of the printing industry: Web offset lithography, web letterpress, rotogravure, and flexography.39 (Screen printing and manual sheet-fed techniques are not included in this source category description.) Printing may be performed on coated or uncoated paper and on other surfaces, as in metal decorating and some fabric coating. The material to receive the printing is called the substrate. The distinction between printing and paper coating, both of which may employ rotogravure or lithographic methods, is that printing invariably involves the application of ink by a printing press, whereas paper coating does not involve that process. Printing and paper coating do, however, have these elements in common: Application of a relatively high-solvent-content material to the surface of a moving web or film; rapid solvent evaporation by movement of heated air across the wet surface; and solvent-laden air exhausted from the system. Printing inks vary widely in composition, but all consist of three major components: Pigments, which produce the desired colors and are composed of finely divided organic and inorganic materials; binders, the solid components that lock the pigments to the substrate and are composed of organic resins and polymers or, in some inks, oils and rosins; and solvents, which dissolve or disperse the pigments and binders and are usually composed of organic compounds. The binder and solvent make up the ‘‘vehicle’’ part of the ink. The solvent evaporates from the ink into the atmosphere during the drying process. VOCs are the primary pollutant of concern from printing operations. Such emissions vary with the printing process, ink formulation and coverage, press size and speed, and operating time. The type of paper (coated or uncoated) has little effect on the quantity of emissions, although low levels of VOC emissions are derived from the paper stock during drying. Most of the solvent contained in the ink and used for dampening and cleanup is eventually emitted into the atmosphere; however, some solvent does remain with the printed product leaving the 39 AP–42, Chapter 4.9—AP–42, https:// www.epa.gov/ttn/chief/ap42/ch04/. VerDate Mar<15>2010 17:53 Jul 16, 2014 Jkt 232001 plant and is released to the atmosphere later. Overall, VOC emissions can be computed using a material balance concept, except in cases where a direct flame dryer is used and some of the solvent is thermally degraded. 2. What is in the proposed General Air Quality Permit for New or Modified True Minor Source Graphic Arts and Printing Operations? This proposed general permit would apply to the construction of new, true minor source graphic arts and printing facilities or the modification of existing, true minor source facilities, located in Indian country. The proposed permit requires that the permittee maintain and operate each affected emission unit and any associated air pollution control equipment, considering the manufacturer’s recommended operating procedures, so as to minimize emissions of NSR regulated pollutants. The reviewing authority will determine whether the permittee is using acceptable operating and maintenance procedures based on monitoring results, review of operating and maintenance procedures, and inspection of the permitted source. (Failure to meet these requirements would constitute a violation of the permit.) This proposed general permit is not available to sources that are major sources of hazardous air pollutants (HAPs). Under section 112 of the CAA, a source is considered major for HAPs if it emits 25 tpy or more of any combination of HAPs or 10 tpy of any single HAP. We are proposing that the general permit for this source category not be applicable to a major source of HAPs because additional requirements apply to these types of source and we believe the general permits should be reserved for sources with straightforward permitting requirements. We believe that permit applications for such major sources should receive greater scrutiny than a general permit would provide. We welcome comment on this issue. The proposed permit requires that VOC emissions from an individual printing press (i.e., printing line) not exceed 25 tpy. We included this requirement to avoid the need for addon control requirements. We believe smaller printing presses (i.e., those that emit less than 25 tpy of VOC) do not warrant the need for add-on controls. Sources applying for this permit that nevertheless intend to install add-on controls would not be prohibited from obtaining this general permit, but they would need to be able to demonstrate compliance with the permit without the PO 00000 Frm 00020 Fmt 4701 Sfmt 4702 consideration of controls. Thus, this general permit is only intended for smaller graphic arts and printing operations, as larger operations would likely require more site-specific review and add-on controls. The proposed permit also requires that VOC emissions from the combination of all graphic arts and printing operations (all printing lines at the facility) not exceed certain tpy limitations that vary by ozone area designation and classification. For nonattainment areas, the numerical limitations become more stringent as the classification increases from marginal to extreme. For flexible packaging printing operations, the permit contains VOC content limitations for each coating, ink or adhesive used. However, the permit provides an exemption that allows up to 110 gallons per calendar year of VOCcontaining material to not meet the VOC content limitations standards for graphic arts and printing operations located in areas designated as ozone attainment, unclassifiable, attainment/ unclassifiable, marginal nonattainment, or moderate nonattainment. This is to allow the use of a small amount of specialty coating, inks, or adhesives. For offset lithographic and letterpress printing operations, the permit contains VOC limitations that vary depending upon the type of printing operation. The permit provides limitations for heatset web offset lithographic printing, sheetfed offset lithographic printing and coldset web offset lithographic printing. The permit provides an exemption from VOC limitations for sheet-fed offset lithographic printing operations that use sheet-fed presses with sheet sizes of 11 inches by 17 inches or smaller OR any press with a total fountain solution reservoir of less than 1 gallon. The permit provides additional VOC limits for permitted sources that locate or modify in a serious, severe or extreme ozone nonattainment area for the following materials: • Lithographic ink; • Letterpress ink; • Rotogravure ink; • Flexographic ink non-porous substrate; • Flexographic ink porous substrate; • Flexographic fluorescent ink; • Coating; • Adhesive; and • Fountain solution. The permit requires that: (1) The VOC content of cleaning materials used for cleaning operations not exceed 70 percent by weight; (2) all VOCcontaining material (e.g., inks, adhesives, coatings, thinners, and clean- E:\FR\FM\17JYP5.SGM 17JYP5 Federal Register / Vol. 79, No. 137 / Thursday, July 17, 2014 / Proposed Rules emcdonald on DSK67QTVN1PROD with PROPOSALS5 up solvents) be stored in closed containers with labels that clearly identify the contents of the container; and (3) all waste materials containing VOC (e.g., soiled rags) be stored in sealed containers until properly disposed. The permittee must implement procedures to minimize spills of any VOC-containing material during handling and transfer to and from containers, enclosed systems, waste receptacles and other equipment. The proposed permit contains requirements for new or modified emergency engines, in the event such engines are present at the new or modified graphic arts and printing facility. Each emergency engine must be equipped with a non-resettable hour meter and, if using fuel oil, then it must use diesel or biodiesel containing no more than 15 ppm (0.0015 percent) sulfur by weight. Newer emergency engines—model year 2006 or later for compression ignition engines and 2009 or later for spark ignition engines—must meet certain certification or emission requirements that are contained in the EPA emissions standards at 40 CFR part 89, 40 CFR part 90 and 40 CFR part 1048 or Table 1 to 40 CFR part 60, subpart JJJJ, as applicable. Other, older emergency engines at the new or modified facility are required to meet certain routine maintenance requirements, and must follow the manufacturer’s emission-related operation and maintenance instructions or the permittee must develop and implement a maintenance plan, which must provide, to the extent practicable, for the maintenance and operation of the engine in a manner consistent with good air pollution control practice for minimizing emissions. The proposed permit includes monitoring that is sufficient to ensure compliance with the emission limitations that apply to the source. Compliance would include requiring monitoring the usage of VOC-containing materials on a weekly basis and conducting performance testing for emergency engines that are not required to be certified by the manufacturer as meeting those standards and are not in fact so certified. (This requirement is needed since the EPA certification program for certain engines is voluntary.) The proposed permit includes recordkeeping and reporting sufficient to ensure compliance with the monitoring requirements. VerDate Mar<15>2010 17:53 Jul 16, 2014 Jkt 232001 3. Request for Comment on the Proposed General Air Quality Permit for New or Modified True Minor Source Graphics Arts and Printing Operations We request comment on all aspects of the proposed general permit for graphic arts and printing operations. We specifically request comment in the following two areas: (a) Use of Tons Per Year Numbers as Emission Limitations In addition to proposing limits on the VOC content of specified materials, the EPA is also proposing to include annual allowable VOC emission limitations for the graphic arts and printing operations source category. The proposed general permit includes an upper emission limitation of 25 tpy of VOC from an individual printing press (printing line). The proposed permit also provides overall total tpy emissions limitations for all printing lines at the facility, which become more stringent as the classification of the relevant ozone nonattainment area increases.40 Sources will need to monitor their material usage and perform material balance calculations using the calculator we are providing to ensure they are staying within these tpy limitations. We opted to not propose surrogate throughput limits for graphic arts and printing operations, as we have for one other source category, because of the diversity of printing lines and materials that a facility may employ. It would be very difficult to set a material usage throughput limit that would have broad applicability. In addition, providing actual emissions limitations directly in the permit ensures the protection of air quality, while at the same time providing the source with flexibility regarding the types of printing lines and materials they use. We request comment both on the appropriateness of establishing annual VOC emissions limitations in the permit (versus throughput limits) and on whether the proposed limitations are set at the correct levels. (b) Should we establish requirements that differ from those for attainment, unclassifiable and attainment/ unclassifiable areas for marginal, moderate, serious, severe and extreme ozone nonattainment areas? The proposed permits contain additional requirements for sources that locate in ozone nonattainment areas. 40 Information on these limitations is available at: Background Document: General Air Quality Permit for True Minor Source Graphics Arts and Printing Operations, Docket ID No. EPA–HQ–OAR–2011– 0151, https://www.epa.gov/air/tribal/tribalnsr.html. PO 00000 Frm 00021 Fmt 4701 Sfmt 4702 41865 First, the annual tpy emissions limitations for VOC decline as the classification of ozone nonattainment increases from marginal to extreme. The numbers are set at levels intended to ensure that the sources are not major for HAPs or for NSR purposes. Second, the proposed permit requires lower VOC content levels for materials used at graphic arts and printing operations located in severe or extreme ozone nonattainment areas. Both of these features are meant to ensure that there is extra air quality protection in ozone nonattainment areas with higher classifications. We request comment on whether these additional limitations are needed and, if so, whether they are set at the correct levels. E. Sawmills 1. What is a sawmill facility? A sawmill facility is an operation that processes raw timber into dimensional lumber for shipping and eventual sale. A modern sawmill’s basic operation is much like those of hundreds of years ago; a log enters at one end and dimensional lumber exits at the other end. Sawmill activities include sawing, planing, sanding, chipping and drying wood. Sawmill facilities are common in areas with ample supplies of timber, including the southeast and northwest. A sawmill’s basic operation involves several steps to turn logs into dimensional lumber: • Logs are brought in by logging truck, rail or a log drive to the sawmill; • Logs are scaled either on the way to the mill or upon arrival at the mill; • Debarking removes bark from the logs; • Decking is the process for sorting the logs by species, size and end use (lumber, plywood, chips); • The head saw, head rig or primary saw, breaks the log into cants (unfinished logs to be further processed) and flitches (unfinished planks) with a smooth edge; • Depending upon the species and quality of the log, the cants will be further broken down by either a resaw or a gang edger into multiple flitches and/or boards; • Edging trims all irregular edges off of the flitch, leaving four-sided lumber; • Trimming squares the ends at typical lumber lengths; • Drying removes naturally occurring moisture from the lumber (this can be done with kilns or the lumber can be air-dried); • Planing smoothes the surface of the lumber leaving a uniform width and thickness; and • Shipping transports the finished lumber to market. E:\FR\FM\17JYP5.SGM 17JYP5 41866 Federal Register / Vol. 79, No. 137 / Thursday, July 17, 2014 / Proposed Rules Sawmills typically derive their power from the electric grid. Dryers may be either direct-fired or indirect-heated. Boilers are typically used to provide the heat for dryers. In direct-fired dryers, hot combustion gases from an onsite boiler are blended with recirculated exhaust from the dryer to lower the gas temperature to a level that will not scorch the lumber. In indirect-heated dryers, air is warmed over steam coils and then circulated over the lumber. Dryers typically have one to three heated zones followed by a cooling zone or section. Each heated zone has a hot air source, fans to move the warm air, and an exhaust vent or stack. The cooling section circulates ambient air over the wood to reduce the temperature just before it exits the dryer. The lumber must be cooled before proceeding to the next step in the process. Criteria pollutant emissions of concern are primarily PM from sawing and planing, but also include PM from re-entrained road dust or sawdust particles; VOCs from drying; and NOX from boilers and emergency diesel generators. PM control methods include water sprays and dry control methods (baghouses, fabric filters and cyclones). emcdonald on DSK67QTVN1PROD with PROPOSALS5 2. What is in the proposed General Air Quality Permit for New or Modified True Minor Source Sawmill Facilities? This proposed general permit would apply to the construction of new true minor source sawmills or the modification of existing true minor source sawmills, located in Indian country. The proposed permit requires that the permittee maintain and operate each affected emission unit and any associated air pollution control equipment, considering the manufacturer’s recommended operating procedures, so as to minimize emissions of NSR regulated pollutants. The reviewing authority will determine whether the permittee is using acceptable operating and maintenance procedures based on monitoring results, review of operating and maintenance procedures, and inspection of the permitted source. (Failure to meet these requirements would constitute a violation of the permit.) In creating the proposed sawmill general permit, the EPA considered VOC emissions from kiln drying, surface coating operations, boilers, and emergency engines. We are requesting comment on whether there are other sources of VOC emissions at sawmills that should be included in our analysis. The proposed permit is designed to be as comprehensive as possible and, thus, contains emission limitations VerDate Mar<15>2010 17:53 Jul 16, 2014 Jkt 232001 requirements for the following affected emission units or activities: • Planar mill operations (baghouse/ fabric filter); • Sawmill operations (baghouse/ fabric filter or cyclone); • Open burning (restrictions on); • Boilers; • Emergency engine use; • Fugitive dust control; and • Setbacks. The proposed permit prohibits open burning and restricts the burning and combustion of wood or lumber products to wood-fired boilers. Each identified emissions unit must not result in the discharge of any gases that exhibit 20 percent opacity or greater averaged over any six-consecutive-minute period. Any liquid fuels used at the facility shall contain no more than 0.0015 percent sulfur by weight. The production of finished lumber is limited to 25 million board feet per year based on a 12-month rolling total. The 12-month rolling total is determined by the sum of the current monthly production and the total of the previous 11 months’ production. The purpose of the board feet restriction is to further limit PM emissions from sawmill operations. The limit is in addition to the requirement that sawmills covered by the proposed general permit install cyclones and/or baghouses/fabric filters. The requirement is consistent with the general permits for sawmills in the states of Texas and Oregon.41 In addition to requiring the installation and operation of air pollution controls as described below, the proposed permit limits tpy VOC emissions from all lumber drying kilns and surface coating operations regardless of where the sawmill is planning to locate or modify. The limitations for facilities planning to locate or modify in ozone nonattainment areas are progressively more restrictive as the classification of the ozone nonattainment area increases from marginal to extreme. Planar mill operations must be conducted within enclosed structures and a baghouse or fabric filter must be used to control emissions to the atmosphere. Sawmill operations conducted outdoors (i.e., operations other than planar mill operations) must, at a minimum, be covered and all material handling operations must be controlled using a cyclone or baghouse/fabric filter during all times that the affected emission units 41 Information on board feet limitations is available at: Background Document: General Air Quality Permit for New or Modified True Minor Source Sawmill Facilities, Docket ID No. EPA–HQ– OAR–2011–0151, https://www.epa.gov/air/tribal/ tribalnsr.html. PO 00000 Frm 00022 Fmt 4701 Sfmt 4702 operate. Emissions to the atmosphere from sawmill operations conducted indoors must be controlled using a baghouse or fabric filter. The permittee must develop and implement a fugitive dust control plan. All VOC-containing material (e.g., coatings, thinners, and clean-up solvents) must be stored in closed containers. All waste materials containing VOC (e.g., soiled rags) must be stored in sealed containers until properly disposed. The proposed permit also contains requirements for emergency engines, in the event such engines are present at the new or proposed sawmill facility. Each emergency engine must be equipped with a non-resettable hour meter and, if using fuel oil, then it must use diesel or biodiesel containing no more than 15 ppm (0.0015 percent) sulfur by weight. Newer emergency engines—model year 2006 or later for compression ignition engines and 2009 or later for spark ignition engines—must meet certain certification or emission requirements that are contained in the EPA’s emissions standards at 40 CFR part 89, 40 CFR part 90 and 40 CFR part 1048 or Table 1 to 40 CFR part 60, subpart JJJJ, as applicable. Other, older emergency engines are required to meet certain routine maintenance requirements, and must follow the manufacturer’s emission-related operation and maintenance instructions or the owner/operator must develop and implement their own maintenance plan which must provide to the extent practicable for the maintenance and operation of the engine in a manner consistent with good air pollution control practice for minimizing emissions. The proposed general permit includes monitoring that is sufficient to ensure compliance with the emission limitations that apply to the source, including ensuring that the baghouses/ fabric filters and cyclones are operating properly, conducting weekly opacity observations and fugitive emissions surveys and meeting certain other requirements. The permit also requires performance testing for emergency engines that must meet certain emissions standards, but are neither required to be certified by the manufacturer as meeting those standards, nor are in fact so certified. This requirement is needed since the EPA certification program for certain engines is voluntary. The proposed general permit includes recordkeeping and reporting requirements sufficient to ensure compliance with the monitoring requirements. E:\FR\FM\17JYP5.SGM 17JYP5 Federal Register / Vol. 79, No. 137 / Thursday, July 17, 2014 / Proposed Rules 3. Request for Comment on the Proposed General Air Quality Permit for New or Modified True Minor Source Sawmill Facilities We request comment on all aspects of the general permit for sawmill facilities. We specifically request comment in the following two areas: (a) Use of Tons Per Year Numbers as Emission Limitations The EPA is proposing to include annual allowable emission limitations for the sawmills source category. The proposed general permit includes both a limitation of 25 million board feet on a 12-month rolling total and total tpy VOC emissions limitations for the facility regardless of its location. The tpy limitations become more stringent in ozone nonattainment areas as the classification increases from marginal to extreme.42 We set the proposed VOC emissions limitations at levels that we believe are sufficiently below the NSR major source levels to accommodate any additional VOC emissions from any boilers or emergency engines also present at the facility beyond VOC emissions from lumber drying kilns. Sources will need to monitor their board-foot production and perform emission factor calculations using the calculator and emissions factors that we are providing to ensure they are staying within the permitted tpy limitations. Aside from the maximum 25 million board-feet limit, we opted to not propose surrogate throughput limits for VOC emissions for sawmills, as we did for one other source category, because of the diversity of wood species (and associated emissions) that a sawmill facility may use. It would be very difficult to set a board foot throughput limit that could have broad applicability. Instead, by putting emissions limitations directly in the permit, it provides the source with flexibility on what wood species it uses, while ensuring that air quality is protected. We request comment on the appropriateness of establishing emissions limitations in the permit (versus a limit on throughput) and whether the specified limitations are established at the correct levels. emcdonald on DSK67QTVN1PROD with PROPOSALS5 b. Setback Requirement The proposed general permit requires sawmill facilities to locate at least 150 feet from the nearest property boundary and 1,000 feet from the nearest 42 Information on these limitations is available at: Background Document: General Air Quality Permit for New or Modified True Minor Source Sawmill Facilities, Docket ID No. EPA–HQ–OAR–2011– 0151, https://www.epa.gov/air/tribal/tribalnsr.html. VerDate Mar<15>2010 17:53 Jul 16, 2014 Jkt 232001 residence. This is consistent with the setback requirement in the state of Texas’ 43 general permit that includes a setback requirement for this source category. We believe that this requirement will minimize the impact of emissions from these sources on localized air quality. We request comment on whether we should include this setback requirement in the final permit to provide additional protection against adverse impacts to local air quality. In addition, we request comment on whether there are other neighboring types of buildings from which the setback should apply (e.g., schools, nursing homes) and whether to require owners/operators of the sawmills subject to the permit to use physical markers on their property to show compliance with the setback requirements. VII. Description of the EPA’s Proposed Permit by Rule Program in Indian Country A. What is a permit by rule? For purposes of this proposal, a permit by rule is a standard set of requirements (i.e., emissions limitations, monitoring, recordkeeping and reporting requirements) that can apply to multiple sources with similar emissions and other characteristics. This is similar to a general permit; however, unlike a general permit, we codify the permit by rule requirements into regulation using a formal rulemaking process. (While a proposed general permit is subject to notice and comment in accordance with 40 CFR 49.156 and 40 CFR 49.157, neither the final general permit itself, nor the requirements therein, are added to the Code of Federal Regulations.) For purposes of this proposal, the permit by rule mechanism is a permit streamlining approach that reduces the time permitting authorities must devote to reviewing permit applications and issuing permits for source categories or emissions generating activities that pose a lower environmental concern. We believe that permits by rule offer another cost-effective means of issuing permits, and provide a quicker and simpler alternative mechanism for permitting true minor sources than the site-specific permit or standard general permit process. State and local reviewing authorities use the permit by rule mechanism to 43 The setback requirement in Texas’s general permit is described at: Background Document: General Air Quality Permit for New or Modified True Minor Source Sawmill Facilities, Docket ID No. EPA–HQ–OAR–2011–0151, https:// www.epa.gov/air/tribal/tribalnsr.html. PO 00000 Frm 00023 Fmt 4701 Sfmt 4702 41867 authorize construction of less complex sources, and sources that emit at specified levels below the major stationary source thresholds. The EPA has approved several state or local permits by rule programs into State Implementation Plans (SIPs).44 By this proposal, we would provide similar opportunities for permitting efficiency in Indian country for a specified source category, while also providing a level of protection of air quality comparable to that provided by a general permit. 44 The EPA has approved the following permits by rule: (1) Connecticut for automotive refinishing (‘‘Approval and Promulgation of Air Quality Implementation Plans; Connecticut; VOC Regulations and One-Hour Ozone Attainment Demonstration Shortfall;’’ U.S. Environmental Protection Agency; August 31, 2006 (71 FR 51761); https://www.gpo.gov/fdsys/granule/FR-2006-08-31/ 06-7314/content-detail.html); (2) Iowa for spray booths (‘‘Approval and Promulgation of Implementation Plans; State of Iowa;’’ U.S. Environmental Protection Agency; March 5, 2010 (75 FR 10182); https://www.federalregister.gov/ articles/2013/08/27/2013-20750/approval-andpromulgation-of-implementation-plans-state-ofiowa); (3) Operating PBR for small sources (‘‘Approval and Promulgation of State Implementation Plans and Operating Permits Program; State of Iowa;’’ U.S. Environmental Protection Agency; March 5, 2010 (72 FR 58535); (4) Kansas Class II operating permits for reciprocating engines, evaporative sources, and hot mix asphalt facilities (‘‘Approval and Promulgation of Implementation Plans and Section 112(l) Program for the Issuance of Federally Enforceable State Operating Permits; State of Kansas;’’ U.S. Environmental Protection Agency; July 17, 1995 (60 FR 36361); https://www.gpo.gov/fdsys/pkg/FR-199507-17/html/95-17214.htm); (5) Massachusetts for paint spray booths (‘‘Approval and Promulgation of Air Quality Implementation Plans; Massachusetts; Volatile Organic Compound Regulations;’’ U.S. Environmental Protection Agency; September 3, 1999 (64 FR 48297); (6) Missouri for construction (‘‘Approval and Promulgation of Implementation Plans and Operating Permits Program; State of Missouri;’’ U.S. Environmental Protection Agency; July 11, 2006 (71 FR 38997); https://www.gpo.gov/ fdsys/pkg/FR-2006-07-11/html/06-6092.htm); (7) Nebraska for hot mix asphalt facilities and small animal incinerators (‘‘Approval and Promulgation of Implementation Plans and Operating Permits Program; State of Nebraska;’’ U.S. Environmental Protection Agency; July 10, 2006 (71 FR 38776); https://www.gpo.gov/fdsys/granule/FR-2006-07-10/ E6-10730/content-detail.html); (8) Auto body refinishing facilities; GDFs; boilers and heaters; small printing facilities; and mid-size printing facilities (‘‘Approval and Promulgation of Air Quality Implementation Plans; Ohio; PBR and PTIO;’’ U.S. Environmental Protection Agency; February 20, 2013 (78 FR 11748); https:// www.gpo.gov/fdsys/pkg/FR-2013-02-20/html/201303761.htm); and (9) multiple source categories, such as: Batch mixers; comfort heating; rock crushers; saw mills; vacuum cleaning systems (August 13, 1982 (47 FR 35194) and (‘‘Approval and Promulgation of Implementation Plans; Texas; Revisions to Regulations for Permits by Rule, Control of Air Pollution by Permits for New Construction or Modification, and Federal Operating Permits;’’ U.S. Environmental Protection Agency; November 14, 2003 (68 FR 64543); https:// www.gpo.gov/fdsys/pkg/FR-2003-11-14/pdf/0328416.pdf). E:\FR\FM\17JYP5.SGM 17JYP5 emcdonald on DSK67QTVN1PROD with PROPOSALS5 41868 Federal Register / Vol. 79, No. 137 / Thursday, July 17, 2014 / Proposed Rules B. How would a permit by rule program operate in Indian Country? As discussed in a prior proposed rule (79 FR 2546, January 14, 2014), once the EPA identifies a source category or emissions generating activity for which the permit by rule mechanism would offer permit streamlining benefits, while at the same time protecting air quality, we will codify a nationally applicable permit by rule for those similar sources into a new section of the Indian Country Minor NSR FIP following notice and comment rulemaking procedures. If the permit by rule will apply only at a regional level, then the EPA regional reviewing authority will conduct the rulemaking process, and appropriately limit the applicability of the permit by rule to a specified geographic area. As proposed, permits by rule would be used to address source categories of true minor sources, where the reviewing authority does not need to conduct an in-depth review to evaluate whether an individual source qualifies for the permit (i.e., meets the applicability requirements) and can meet the requirements in the permit. A source category would be covered by a permit by rule if the reviewing authority needs to do nothing more than receive confirmation from an individual source that it meets all appropriate criteria to be eligible for coverage under the permit by rule and that it intends to comply with the operational, monitoring and recordkeeping requirements specified in this rule. (By contrast, under a general permit the source would need to submit a request for coverage to the reviewing authority and receive an approval from that authority before starting source construction.) In our January 14, 2014 proposed rule, we proposed to amend the Indian Country Minor NSR rule general permit provisions at 40 CFR 49.156 to set forth the unique elements of the permits by rule process.45 We intend to take final action on the proposed approach as part of taking final action on the overall January 14, 2014 proposal and are not re-proposing those elements here. In today’s action, in the alternative, we are proposing a permit by rule for the graphic arts and printing source category, as described above. If we finalize the procedure for establishing permits by rule set forth in our January 14, 2014, proposed rule, we will follow the procedure as finalized in 45 ‘‘General Permits and Permits by Rule for the Federal Minor New Source Review Program in Indian Country,’’ U.S. Environmental Protection Agency, January 14, 2014 (79 FR 2546), pp. 2566– 2567, https://www.gpo.gov/fdsys/pkg/FR-2014-0114/pdf/2013-30345.pdf. VerDate Mar<15>2010 17:53 Jul 16, 2014 Jkt 232001 promulgating a final permit by rule for the graphic arts and printing source category. We will only promulgate a permit by rule for the graphic arts and printing source category if, after considering any comments we receive in response to today’s proposal, we conclude that establishing such a permit is appropriate. We seek comment on whether graphic arts and printing operations is an appropriate source category for a permit by rule. C. Requirements of the ESA and NHPA Similar to general permits, prior to seeking coverage under a permit by rule, a source must satisfactorily address the permit requirements related to the ESA and the NHPA. Attached to the request for coverage,46 the EPA provides guidance to assist sources in complying with these requirements. Section V.F. above describes the process for complying with the ESA and NHPA in more detail. We seek comment on the use of this process for the proposed graphic arts and printing operations permit by rule. VIII. Proposed Permits by Rule As an alternative to a general permit, we are proposing to establish a permit by rule, for one source category: Graphic arts and printing operations. We are proposing this source category for a permit by rule based on our determination that this source category emits primarily one pollutant (i.e., VOCs), that there is little variation in the equipment used, and that the compliance requirements are straightforward and readily verifiable. By contrast, the other five source categories in today’s proposal, to varying degrees, involve more complex operations, more than one pollutant and more complex compliance requirements. The source categories are: • Concrete batch plants; • Boilers; • Stationary compression ignition engines; • Stationary spark ignition engines; and • Sawmills. In Section VI. we describe these source categories and the requirements in the proposed permits that warrant a general permit proposal for them, including the multiple emissions units covered. 46 For general permits, we refer to applications submitted to reviewing authorities for approval as requests for coverage. For permits by rule, we are proposing to not require that these requests for coverage be submitted for approval. Instead, sources would be required to notify the EPA by letter that the request for coverage has been completed and that the source qualifies for the permit and will comply with all of its terms and conditions. PO 00000 Frm 00024 Fmt 4701 Sfmt 4702 We are not providing specific regulatory language for the proposed permit by rule but rather are proposing to codify the requirements of the proposed general permit for this source category described in Section VI.D. If, after considering relevant comments received in response to today’s proposed action, we decide to finalize a permit by rule for the source category, we will codify the requirements as contained in the proposed general permit for the source category, including any changes that we deem appropriate based on our review of public comments on the proposed general permit and other relevant information. In other words, whether we use the permit by rule or the standard general permit mechanism, we propose to apply identical requirements to regulate construction and modification activities of affected emission units in the graphic arts and printing operations source category. We believe that the proposed general permit provides the public with a sufficient understanding of the contents of any final rule, and, therefore, satisfies our obligations under section 301(a) of the CAA and the Administrative Procedures Act. The EPA welcomes comments on all aspects of the proposed general permit and proposed permit by rule for the graphic arts and printing operations source category discussed in this notice. In particular, we request comments on whether the permit by rule terms and conditions for graphic arts and printing operations should be identical to the general permit terms and conditions, or whether they should differ. IX. Implementation Documents and Tools We are providing several tools and documents to assist sources with obtaining coverage under the general permits and permit by rule for the six source categories that are the subject of today’s proposal. The tools are drafted based on our preferred approach of general permits. If we decide to issue a permit by rule for the graphic arts and printing operations source category as we are proposing in the alternative today, then we will need to adjust the wording in the documents to reflect that tools being made available are for a permit by rule and not a general permit. The background document for graphic arts and printing operations supports both our general permit proposal and permit by rule proposal, in the alternative; therefore, the document cites both general permits and permits by rule as the permit types it supports. The tools consist of the following six types of documents: E:\FR\FM\17JYP5.SGM 17JYP5 emcdonald on DSK67QTVN1PROD with PROPOSALS5 Federal Register / Vol. 79, No. 137 / Thursday, July 17, 2014 / Proposed Rules Request for Coverage: This form is for sources seeking to use general permits and is essentially an application to request coverage under a general permit. The application asks for contact and location information, as well as more indepth operational and source-specific information. The application will also guide sources through processes to comply with permit requirements related to the ESA and the NHPA. The general permit application for graphic arts and printing operations is more streamlined because sources in the category represent more straightforward operations, largely involve one air pollutant (i.e., VOCs) and, therefore, necessitate less intensive review for approval. The general permit application form for the category asks for basic solvent usage information and whether the source has complied or will comply with relevant requirements. By contrast, the general permit applications for concrete batch plants, engines, boilers and sawmills request more detailed technical information about the proposed facility in question because these facilities are more complex and can involve multiple operations and pollutants. For graphic arts and printing operations, this form also serves as an application for sources seeking coverage under a permit by rule should the EPA decide to issue one for this category. In such circumstances, the source would need to complete the shortened application and keep a record on file. Successfully completing the application will enable the source to determine if it can certify to the reviewing authority that it meets the permit’s eligibility terms and conditions, which the source would need to do via a letter in order to begin its construction or modification. Questionnaire: This tool is tailored to each source category and guides sources through a series of questions to determine whether it is eligible for coverage under a general permit. It is not required to be completed or submitted. First, the source needs to determine whether it is a true minor source and, therefore, subject to the requirements of the minor NSR rule for Indian country. To do this, a source needs to perform a PTE analysis of all of its new, modified and existing emissions units (see PTE calculator below). If the source determines that it is a true minor, the questionnaire asks the source to consider a series of questions to determine if it qualifies for the specific general permit or permit by rule. If the source does not qualify for coverage, then it must seek a sitespecific permit under the minor source VerDate Mar<15>2010 17:53 Jul 16, 2014 Jkt 232001 program (or a major source permit, if appropriate). Instructions: The document assists sources with information that may be useful in completing the request for coverage application. Permit Terms and Conditions: The permit is a specific document for each source category that lays out the general and specific terms and conditions of the permit, including the specific emission limitations and standards and monitoring, recordkeeping, reporting and notification requirements. PTE Calculator: This spreadsheetbased tool helps sources in specific source categories calculate the PTE of their affected emissions units, using data the source is expected to have on hand, such as equipment specifications. Background Documents: These documents are provided as a reference and contain important information: • Source category definition and characterization; • State minor source permit programs for that category used for comparison; • Requirements for general permits and permits by rule for that category; and • Threshold (emission limitations) development and rationale for that category. All of these documents are available online at https://www.epa.gov/air/tribal/ tribalnsr.html and Docket ID No. EPA– HQ–OAR–2011–0151. X. Additional Area Where Comment is Being Sought A. Should general permits and permits by rule be made available for sources in the same source category? In our January 14, 2014 proposed rule, the EPA requested comments on whether, for certain source categories, the EPA should structure the permits so that eligible true minor sources can receive coverage under permits by rule and synthetic minor sources receive coverage under general permits. In addition, just as we proposed that general permits are more appropriate for more complex source categories, we requested comment on whether general permits (and not permits by rule) are more appropriate for major sources that seek to become ‘‘synthetic’’ minor sources. And, as we proposed that permits by rule are more appropriate for less complex source categories, we requested comments on whether permits by rule (and not general permits) are more appropriate for true minor sources. In this action, we request comment only on whether this concept should be applied to the graphic arts and printing operations source category. PO 00000 Frm 00025 Fmt 4701 Sfmt 4702 41869 In the docket, a background document is provided for this source category, which includes a summary of National Emissions Inventory data for the category. XI. Proposed Rule Change to the Indian Country Minor NSR Rule We are proposing one change to one provision in the existing Indian country minor NSR rule addressing the time period within which the reviewing authority must make a determination on whether a request for coverage under a general permit is complete and to complete its review of the request for coverage. We are proposing this change only for the general permit for the graphic arts and printing operations source category. The Indian County Minor NSR rule currently requires the reviewing authority to determine whether a request for coverage under a general permit is complete within 45 days of receiving the request (40 CFR 49.156(e)(4)) and to take final action on the request within 90 days of receiving a complete request (40 CFR 49.156(e)(3)). For the proposed general permit for the graphic arts and printing operations source category, we are proposing to shorten the time for determining whether a request for coverage is complete to 15 days (by that date the reviewing authority must either determine that the request for coverage is complete or request any additional information) and to shorten the time within which the reviewing authority must take final action on the request to 45 days. We explained our general rationale for taking this approach for some, but not all, general permits in our January 14, 2014, proposed rule. We are proposing the shortened time frames for the graphic arts and printing operations source category only. We also propose to provide the reviewing authority the option of automatically denying a source’s request for coverage if the source fails to submit any additional requested information within 15 days of receiving the request from the reviewing authority to remain consistent with our intent to provide a streamlined notification and review process. If a reviewing authority denies a request for coverage because a source fails to submit requested information by the deadline, the source may re-apply at a later date to re-initiate the request for coverage. We believe that a shortened application review process for the graphic arts and printing operations general permit is justified because the streamlined nature of the general permit for the graphic arts and printing operations source category is E:\FR\FM\17JYP5.SGM 17JYP5 41870 Federal Register / Vol. 79, No. 137 / Thursday, July 17, 2014 / Proposed Rules inconsistent with lengthy and potentially open-ended ongoing exchanges with applicants to obtain necessary information and is not the best use of limited resources. The applications are lengthier for the other four source categories in today’s proposal and, therefore, a lengthier 90 day review process is appropriate for those categories. In Section IX., we explain our reasoning for why the application is shorter for graphic arts and printing operations and longer for the other four categories. Allowing this streamlining (combined with a shorter application for this same category) will allow for reduced processing time for a general permit coverage request for this category and a reduction in information required to be included in requests for coverage. XII. Statutory and Executive Order Reviews A. Executive Order 12866: Regulatory Planning and Review and Executive Order 13563: Improving Regulation and Regulatory Review This action is not a ‘‘significant regulatory action’’ under the terms of EO 12866 (58 FR 51735, October 4, 1993) and is, therefore, not subject to review under EOs 12866 and 13563 (76 FR 3821, January 21, 2011). B. Paperwork Reduction Act This action does not impose an information collection burden under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. Burden is defined at 5 CFR 1320.3(b). This action merely proposes to establish general permits and/or permits by rule to satisfy the requirements of the Indian Country Minor NSR rule. Any burden associated with information required to be collected pursuant to the proposed general permits and/or permit by rule has already been accounted for in the approved information collection request for the Indian Country Minor NSR rule. Further, any use of the general permits and/or permit by rule is strictly voluntary. Therefore, this action does not impose an information collection burden. emcdonald on DSK67QTVN1PROD with PROPOSALS5 C. Regulatory Flexibility Act The Regulatory Flexibility Act generally requires an agency to prepare a regulatory flexibility analysis of any rule subject to notice and comment rulemaking requirements under the Administrative Procedure Act or any other statute unless the agency certifies that the rule will not have a significant economic impact on a substantial number of small entities. Small entities VerDate Mar<15>2010 17:53 Jul 16, 2014 Jkt 232001 include small businesses, small organizations, and small governmental jurisdictions. For purposes of assessing the impacts of today’s rule on small entities, small entity is defined as: (1) A small business as defined by the Small Business Administration’s regulations at 13 CFR 121.201; (2) a small governmental jurisdiction that is a government of a city, county, town, school district or special district with a population of less than 50,000; and (3) a small organization that is any not-for-profit enterprise which is independently owned and operated and is not dominant in its field. After considering the economic impacts of today’s proposed rule on small entities, I certify that this action will not have a significant economic impact on a substantial number of small entities. The EPA analyzed the impact of streamlined permitting on small entities in the Review of New Sources and Modifications in Indian Country (76 FR 38748, July 1, 2011). Today’s action will not impose any requirements on small entities, as it merely implements a particular aspect of the Review of New Sources and Modifications in Indian Country. D. Unfunded Mandates Reform Act This action contains no federal mandates under the provisions of Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), 2 U.S.C. 1531– 1538 for state, local, or tribal governments or the private sector. This action imposes no enforceable duty on any state, local or tribal government or the private sector. Therefore, this action is not subject to the requirements of sections 202 and 205 of the UMRA. This action is also not subject to the requirements of section 203 of UMRA because it contains no regulatory requirements that might significantly or uniquely affect small governments. This rule has no requirements applicable to small governments and, as such, does not impose obligations upon them. E. Executive Order 13132: Federalism This action does not have federalism implications. It will not have substantial direct effects on the states, on the relationship between the national government and the states, or on the distribution of power and responsibilities among the various levels of government, as specified in EO 13132. This action merely proposes to provide sources in Indian country with streamlined permitting opportunities that are generally available in states outside of Indian country. It does not impose any new obligations or PO 00000 Frm 00026 Fmt 4701 Sfmt 4702 enforceable duties on any state, local or tribal government or the private sector. Thus, EO 13132 does not apply to this rule. In the spirit of EO 13132, and consistent with the EPA policy to promote communications between the EPA and state and local governments, the EPA specifically solicits comment on this proposed action from state and local officials. F. Executive Order 13175: Consultation and Coordination With Indian Tribal Governments Pursuant to the EO 13175 (65 FR 67249, November 9, 2000), the EPA may not issue a regulation that has tribal implications, that imposes substantial direct compliance costs, and that is not required by statute, unless the federal government provides the funds necessary to pay the direct compliance costs incurred by tribal governments, or the EPA consults with tribal officials early in the process of developing the proposed regulation and develops a tribal summary impact statement. The EPA has concluded that this action will not impose duties or responsibilities on tribes, although it will have tribal implications. The EPA has conducted outreach via on-going monthly meetings with tribal environmental professionals in the development of this proposed action. This proposal reflects priorities for developing permits, comments on the general permits and suggestions for developing permits by rules developed as a result of that outreach. The EPA will offer consultation to elected tribal officials immediately after proposal to provide an opportunity for meaningful and timely input into the development of this regulation. The EPA specifically solicits additional comment on this proposed action from tribal officials. G. Executive Order 13045: Protection of Children From Environmental Health Risks and Safety Risks The EPA interprets EO 13045 (62 FR 19885, April 23, 1997) as applying only to those regulatory actions that concern health or safety risks, such that the analysis required under section 5–501 of the EO has the potential to influence the regulation. This action is not subject to EO 13045 because it does not establish an environmental standard intended to mitigate health or safety risks. H. Executive Order 13211: Actions That Significantly Affect Energy Supply, Distribution, or Use This action is not subject to EO 13211 (66 FR 28355 (May 22, 2001)) because E:\FR\FM\17JYP5.SGM 17JYP5 Federal Register / Vol. 79, No. 137 / Thursday, July 17, 2014 / Proposed Rules it is not a significant regulatory action under EO 12866. I. National Technology Transfer and Advancement Act Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (‘‘NTTAA’’), Public Law 104–113, 12(d) (15 U.S.C. 272 note) directs the EPA to use voluntary consensus standards in its regulatory activities unless to do so would be inconsistent with applicable law or otherwise impractical. Voluntary consensus standards are technical standards (e.g., materials specifications, test methods, sampling procedures, and business practices) that are developed or adopted by voluntary consensus standards bodies. The NTTAA directs the EPA to provide Congress, through the Office of Management and Budget, explanations when the agency decides not to use available and applicable voluntary consensus standards. The proposed rulemaking involves technical standards. In the proposed permits the EPA proposes the use of EPA Methods 5, 7, 9, 10, 18, 22 and 25A of 40 CFR part 60, Appendix A.47 Three voluntary consensus standards were identified as applicable for purposes of this proposal: on any available voluntary consensus standards that can used as alternatives to the emissions measurement standards in the General Air Quality Permit for New or Modified True Minor Source Spark Ignition Engines can be found in: ‘‘Voluntary Consensus Standard Results for General Permits and Permits by Rule for the Indian Country Minor New Source Review Program; 40 CFR part 49, subparts 156(c) and 162,’’ from Robin Segall, Acting Group Leader, Measurement Technology Group, to Laura McKelvey, Community and Tribal Programs Group, February 7, 2014, Docket ID No. EPA–HQ–OAR–2011–0151, https:// www.epa.gov/air/tribal/tribalnsr.html. emcdonald on DSK67QTVN1PROD with PROPOSALS5 47 Information VerDate Mar<15>2010 17:53 Jul 16, 2014 Jkt 232001 1.

The EPA welcomes comments on this aspect of the proposed rulemaking and, specifically, invites the public to identify potentially-applicable voluntary consensus standards and to explain why such standards should be used in this regulation. J. Executive Order 12898: Federal Actions To Address Environmental Justice in Minority Populations and Low-Income Populations E.O. 12898 (59 FR 7629 (Feb. 16, 1994)) establishes federal executive policy on environmental justice. Its main provision directs federal agencies, to the greatest extent practicable and permitted by law, to make environmental justice part of their mission by identifying and addressing, as appropriate, disproportionately high and adverse human health or environmental effects of its programs, policies, and activities on minorities and low-income populations in the United States. The EPA has determined that this proposed rule will not have disproportionately high and adverse human health or environmental effects on minority or low-income populations PO 00000 Frm 00027 Fmt 4701 Sfmt 9990 41871 because it does not affect the level of protection provided to human health or the environment. This proposed rule merely implements certain aspects of the Review of New Sources and Modifications in Indian Country. As such, this proposed action will not have a disproportionately high and adverse human health or environmental effects on minorities and low-income populations in the United States. Our primary goal in developing the general permits and permits by rule is to ensure that air resources in Indian country will be protected in the manner intended by the CAA. In particular, this rule will help minimize air quality impacts from new or modified true minor sources in Indian country. In addition, we seek to establish a flexible preconstruction permitting program for minor sources in Indian country that is comparable to similar programs in neighboring states to create a more level regulatory playing field for owners and operators within and outside of Indian country. This rule will reduce an existing disparity by filling the regulatory gap.

II. Purpose

A. Proposed Action

In July 2011, the EPA issued the Indian Country Minor NSR rule that
established, among other things, the requirements and process for the
preconstruction permitting of minor sources in Indian country. Under
the rule, on or after September 2, 2014, an owner or operator must
obtain a preconstruction permit from the reviewing authority \1\ if the
source will

[[Page 41849]]

construct a new true minor source,\2\ or will modify an existing true
minor source in Indian country. The rule also specified the process and
requirements for using general permits as a streamlined permitting
approach to authorize construction and modifications at true minor
sources. General permits streamline the preconstruction permitting of
new or modified true minor sources because they involve the issuance of
one permit that can apply to multiple stationary sources that have
similar emissions units.
---------------------------------------------------------------------------

\1\ In this document, reviewing authority refers to an EPA
regional office. However, tribes can become reviewing authorities if
they decide to assume responsibility for implementing the minor NSR
program in their area and are either delegated authority to
implement the Indian Country Minor NSR rule or establish and obtain
the EPA's approval of their own minor source program.
\2\ True minor source means a source that emits, or has the
potential to emit, regulated NSR pollutants in amounts that are less
than the major source thresholds under either the Prevention of
Significant Deterioration program at 40 CFR 52.21, or the Major NSR
Program for Nonattainment Areas in Indian Country at 40 CFR 49.166
through 49.173, but equal to or greater than the minor NSR
thresholds in 40 CFR 49.153, without the need to take an enforceable
restriction to reduce its potential to emit (PTE) to such levels.
The PTE includes fugitive emissions, to the extent that they are
quantifiable, only if the source belongs to one of the 28 source
categories listed in part 51, Appendix S, paragraph II.A.4(iii) or
40 CFR 52.21(b)(1)(iii), as applicable.
---------------------------------------------------------------------------

On January 14, 2014, the EPA proposed general permits \3\ for use
in Indian country pursuant to the Indian Country Minor NSR rule for new
or modified true minor sources in the following five source categories:
Hot mix asphalt plants; stone quarrying, crushing, and screening
facilities; auto body repair and miscellaneous surface coating
operations; gasoline dispensing facilities (GDFs); and petroleum dry
cleaning facilities. In the alternative, the EPA also proposed permits
by rule for use in Indian country for new or modified minor sources in
three of the source categories: Auto body repair and miscellaneous
surface coating operations; GDFs; and petroleum dry cleaning
facilities. The EPA also proposed certain changes to the Indian Country
Minor NSR rule. The proposed changes include: Extending the deadline by
when true minor sources in the oil and gas sector must receive minor
source NSR permits; and allowing general permits and permits by rule
for specific categories to be used to create synthetic minor sources.
In the prior action, we also sought comment on a number of issues, some
of which relate to the source categories contained in this proposal.

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

Today's proposal addresses a second group of activities; the EPA is
proposing the use of two types of minor NSR preconstruction permits to
help streamline permitting of true minor sources that construct or
modify in Indian country and that belong to one of six additional
source categories. The first type of permit is a general permit. A
general permit is a document that the EPA will make available online
that will contain all of the emissions limitations, monitoring,
recordkeeping and reporting requirements to which a source in a given
source category would be subject. Sources seeking coverage under a
tribal general permit will need to submit a request for coverage or
application to the EPA. The second type is a permit by rule, which uses
a regulatory-type structure to permit sources by pre-authorizing
construction and modification activities carried out in accordance with
the permit's requirements. Sources seeking coverage under a tribal
permit by rule must notify the EPA that it meets the terms of coverage
and is complying with the permit's conditions, but does not need to
await approval of a request for coverage.
As our preferred approach, we are proposing general permits for the
six source categories: Concrete batch plants; boilers; stationary spark
ignition engines; stationary compression ignition engines; graphic arts
and printing operations; and sawmills. Specifically, we are proposing
general permits for these source categories for permitting affected
emissions units and emissions-generating activities in these source
categories. As an alternative, for graphic arts and printing
operations, the EPA is also requesting comment on whether, in lieu of
establishing a general permit, we should instead adopt a permit by
rule.
We are making available various permit implementation documents and
tools on which we request public comment. In a prior action \4\ in
which we also proposed general permits and permits by rule for certain
source categories of minor sources in Indian country, we proposed the
regulatory framework that the EPA will use to establish permits by
rule. That proposed regulatory framework is also relevant here.

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

B. Areas Where the EPA Is Seeking Comment

In this proposal, we are seeking comment on the following areas:
(1) All aspects of the permit documents and implementation tools of
the following six source categories (Sections VI. and IX.):
a. Concrete batch plants;
b. Boilers;
c. Stationary compression ignition engines;
d. Stationary spark ignition engines;
e. Graphic arts and printing operations; and
f. Sawmills.
(2) The appropriateness of using a streamlined general permit/
permit by rule application for one source category (Section IX.):
a. Graphic arts and printing operations.
(3) Different aspects of the EPA's conclusion on its control
technology review that, because the control measures in this proposal
are currently used by other similar sources in other areas of the
country, the measures in the proposed permits are technically and
economically feasible, and cost effective (Section V.);
(4) The process for sources to address the requirements of the
Endangered Species Act (ESA) and the National Historic Preservation Act
(NHPA) with respect to the six categories in today's proposal (Sections
V. and VII.);
(5) Use of throughput limits and capacity limits as surrogate for
tons per year (tpy) allowable emission limitations, or, alternatively,
establishment of annual allowable emission limitations for each
pollutant, and the use of throughput limits as surrogate monitoring
measures to demonstrate compliance with tpy annual allowable emission
limitations (Sections V. and VI.);
(6) Finalizing both permitting mechanisms for graphic arts and
printing operations by providing authorization to construct or modify
true minor sources in this category via permits by rule and by
providing enforceable limitations to create synthetic minor sources in
this category via general permits (Section X.); and
(7) Proposed rule changes to the Indian Country Minor NSR rule in
one area (Section XI.):
a. Shortening the general permit application review process from 90
to 45 days for one source category out of the six in this proposal for
which the EPA believes it is appropriate:
i. Graphic arts and printing operations.
In this proposal, we are not seeking comment on several issues
already

[[Page 41850]]

proposed in the January 14, 2014, action that more broadly cover policy
and other issues related generally to the functioning and use of
general permits and permits by rule in Indian country. The Agency's
final decision on those issues, though, has the potential to impact
sources in the source categories proposed in this action. Those issues
include the following:
(1) Several administrative aspects of general permits, including:
a. Whether the EPA's proposed approach of incorporating by
reference each reviewing authority's approval of a request for coverage
into the general permit is necessary and appropriate; and
b. The appropriateness of proposed permit terms related to the
reviewing authority's ability to reopen, revise, or terminate an
individual approval of coverage under the general permit;
(2) The regulatory framework that the EPA is proposing as an
alternative to use to establish permits by rule and the streamlined
review and issuance process that the EPA is proposing whereby a source
can become covered by a permit by rule by notifying the EPA that it
qualifies for the permit, meets the terms of coverage and is complying
with the permit's conditions (but not having to wait for the reviewing
authority's approval);
(3) Proposal to change the policy in the Indian Country Minor NSR
rule to allow the use of both general permits and permits by rule to
create synthetic minor sources;
(4) Use of more than one general permit and/or permit by rule for a
source at a single location;
(5) Additional source categories for which the EPA is planning to
propose general permits and/or permits by rule; and
(6) Proposed rule changes to the Indian Country Minor NSR rule in
four areas in three provisions:
a. Adjusting the deadline by which minor sources covered by a
general permit need to obtain a preconstruction permit;
b. Extending the permitting deadline for true minor sources within
the oil and gas source category;
c. Removing a provision to make clear that sources may seek
coverage under a general permit as soon as it is effective and need not
wait an additional 4 months; and
d. Adjusting the deadline for oil and gas sources for certain
registration-related requirements to be consistent with the proposed
permitting deadline extension.

III. Background

A. Tribal Air Rule

On February 12, 1998,\5\ the EPA used its authority under section
301(d) of the Clean Air Act (CAA) to find that we would not treat
tribal governments the same as states with respect to specific plan
submittal and implementation deadlines under the CAA for National
Ambient Air Quality Standards (NAAQS)-related requirements. This
finding applied to many section 110 requirements, including
requirements under section 110(a)(2)(c) to submit a program to regulate
the modification and construction of any stationary source as necessary
to ensure that the NAAQS are achieved. Although we determined that
Indian tribes were not obligated to implement a permitting program, the
EPA also made clear that we continue to have a general obligation under
the CAA to ensure the protection of air quality throughout Indian
country. To that end, we also used our authority under sections 301(a)
and 301(d)(4) to establish a requirement to promulgate such federal
implementation plan (FIP) provisions as are necessary or appropriate to
protect air quality in Indian country (40 CFR 49.11(a)). For a number
of years, the only federal CAA NSR permitting program that applied in
Indian country was the major NSR program for areas meeting the NAAQS
(``attainment'' areas) or areas for which there is insufficient
information to determine whether they meet the NAAQS
(``unclassifiable'' areas). We call this program the Prevention of
Significant Deterioration (PSD) program (40 CFR 52.21). No federal NSR
permitting program has covered minor sources or major sources in
nonattainment areas. Nor was there a readily available way for major
sources to take enforceable limits and become synthetic minor sources.

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

On August 21, 2006, the EPA proposed the regulation: ``Review of
New Sources and Modifications in Indian Country'' (i.e., the Indian
Country NSR rule).\6\ Within this regulation, the EPA proposed to
protect air quality in Indian country by establishing a FIP program to
regulate the modification and construction of minor stationary sources
consistent with the requirements of section 110(a)(2)(c) of the CAA. We
call this part of the Indian Country NSR rule the Indian Country Minor
NSR rule. Under the Indian Country Minor NSR rule, we proposed to fill
a regulatory gap and provide a mechanism for issuing preconstruction
permits for the construction of new minor sources and certain
modifications of major and minor sources in Indian country. In
developing the rule, the EPA conducted extensive outreach and
consultation and provided an extensive public comment period that ended
on March 20, 2007. The comments we received provided detailed
information specific to Indian country and the final Indian Country
Minor NSR rule incorporated many of the suggestions we received. We
promulgated final rules on July 1, 2011,\7\ and the FIP became
effective on August 30, 2011.\8\

\8\ On January 17, 2014, the United States Court of Appeals for
the District of Columbia Circuit issued an opinion and judgment
vacating the Indian Country NSR rule with respect to non-reservation
areas of Indian country. As a result, EPA does not currently have
minor source NSR permitting authority in non-reservation areas of
Indian country and any general permits and permits by rule issued
under the Indian Country Minor NSR rule will not be immediately
available in such areas of Indian country. Importantly, the court's
decision does not affect the Indian Country Minor NSR rule with
respect to reservations, whether formal or informal, and any final
general permits and permits by rule issued under the Indian Country
Minor NSR rule will be available in those areas. The EPA is
currently considering, but has not yet determined, how best to
implement the court's decision.
---------------------------------------------------------------------------

B. Indian Country Minor NSR Rule

1. What is the Indian Country Minor NSR rule?
The Indian Country Minor NSR rule applies to new and modified minor
stationary sources and to minor modifications at existing major
stationary sources located in Indian country where there is no EPA-
approved program in place. The rule also includes a pre-construction
permits program for major sources proposing to construct in areas of
Indian country that have not attained one or more NAAQS, i.e.,
nonattainment areas. After September 2, 2014, any new stationary
sources that will emit, or will have the PTE, a regulated NSR pollutant
in amounts that will be: (1) Equal to or greater than the minor NSR
thresholds, established in the Indian Country Minor NSR rule; and (2)
less than the amount that would qualify the source as a major source
for purposes of the PSD or nonattainment major NSR programs,

[[Page 41851]]

must apply for and obtain a minor NSR permit before commencing
construction of the new source. Likewise, any existing stationary
source (minor or major) must apply for and obtain a minor NSR permit
before commencing construction of a physical or operational change that
will increase the allowable emissions of the stationary source by more
than the specified minor NSR threshold amounts, if the change does not
otherwise trigger the permitting requirements of the PSD or
nonattainment major NSR program(s).\9\
---------------------------------------------------------------------------

\9\ A source may, however, be subject to certain monitoring,
recordkeeping and reporting (MRR) requirements under the major NSR
programs, if the change has a reasonable possibility of resulting in
a major modification. A source may be subject to both the Indian
Country Minor NSR program and the reasonable possibility of being
subject to the MRR requirements of the major NSR program(s).
---------------------------------------------------------------------------

Among other things, the Indian Country Minor NSR rule created a
framework for the EPA to streamline the issuance of preconstruction
permits to true minor sources by using general permits. We explain this
framework further in the sections below.
2. What is a true minor source and how does it differ from a
synthetic minor source?
``True minor source'' means a source that emits, or has the
potential to emit, regulated NSR pollutants in amounts that are less
than the major source thresholds under either the PSD program at 40 CFR
52.21, or the Major NSR program for Nonattainment Areas in Indian
Country at 40 CFR 49.166 through 49.173, but equal to or greater than
the minor NSR thresholds in 40 CFR 49.153, without the need to take an
enforceable restriction to reduce its PTE to such levels. The PTE
includes fugitive emissions, to the extent that they are quantifiable,
only if the source belongs to one of the 28 source categories listed in
40 CFR part 51, Appendix S, paragraph II.A.4(iii) or 40 CFR
52.21(b)(1)(iii), as applicable. For example, a hot mix asphalt
facility, located in a sulfur dioxide (SO2) attainment area,
that has a maximum potential to emit of 135 tpy of SO2,
without the need to take an enforceable restriction to reduce its PTE
to such levels, would qualify as a true minor source. By contrast,
``synthetic minor source'' means a source that otherwise has the
potential to emit regulated NSR pollutants in amounts that are at or
above those for major sources, but that has taken a restriction so that
its PTE is less than such amounts. Such restrictions must be
enforceable as a legal and practical matter. For example, a hot mix
asphalt facility, located in an SO2 attainment area, that
has an unrestricted PTE of 270 tpy, but that is legally constrained to
emit only 135 tpy of SO2 because the source has taken a
throughput limit made enforceable through a permit (i.e., a limit on
how much hot mix product it can produce), would qualify as a synthetic
minor source. In the preamble to both the proposed and final Indian
Country Minor NSR rule, the EPA indicated that it would not use general
permits to allow otherwise major sources to create synthetic minor
sources.\10\
---------------------------------------------------------------------------

\10\ Note that the current regulatory language in the Tribal
Minor NSR rule does not address the use of general permits in this
manner.
---------------------------------------------------------------------------

3. What are the minor NSR thresholds?
The ``minor NSR thresholds'' establish cutoff levels for each
regulated NSR pollutant. If a source naturally has a PTE in amounts
lower than the thresholds, then it is exempt from the Indian Country
Minor NSR rule (see Table 2 and 40 CFR 49.153) for that pollutant. New
or modified sources which naturally have a PTE in amounts that are: (1)
Equal to or greater than the minor NSR thresholds; and (2) less than
the major NSR thresholds (generally 100 to 250 tpy) are ``minor
sources'' of emissions and subject to the Indian Country Minor NSR rule
requirements at 40 CFR 49.151 through 161.

Table 2--Minor NSR Thresholds for Sources in Indian Country \11\
------------------------------------------------------------------------
Minor NSR Minor NSR
thresholds for thresholds for
Regulated NSR pollutant nonattainment attainment

organic compounds).................
------------------------------------------------------------------------

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

\11\ If part of a tribe's area of Indian country is designated
as attainment and another part as nonattainment, the applicable
threshold for a proposed source or modification is determined based
on the designation where the source would be located. If the source
straddles the two areas, the more stringent thresholds apply.
\12\ In extreme ozone nonattainment areas, section 182(e)(2) of
the CAA requires any change at a major source that results in any
increase in emissions to be subject to major NSR permitting. In
other words, any changes to existing major sources in extreme ozone
nonattainment areas are subject to a ``0'' tpy threshold, but that
threshold does not apply to minor sources.
\13\ Id.
---------------------------------------------------------------------------

4. What is a general permit?
The Indian Country Minor NSR rule specified the process and
requirements for using general permits to authorize construction of and
modifications at true minor sources as a streamlined permitting
approach. A general permit, for purposes of this action, is a permit
document that contains standardized requirements that multiple
stationary sources can use. The EPA may issue a

[[Page 41852]]

general permit for categories of emissions units or stationary sources
that are similar in nature, have substantially similar emissions, and
would be subject to the same or substantially similar permit
requirements.\14\ ``Similar in nature'' refers to size, processes, and
operating conditions. The purpose of a general permit is to provide for
protection of air quality while simplifying the permit process for
similar minor sources. General permits offer a cost-effective means of
issuing permits and provide a quicker and simpler mechanism for
permitting minor sources than the site-specific permitting process.

Country,'' U.S. Environmental Protection Agency, July 1, 2011 (76 FR
38770), https://www.federalregister.gov/articles/2011/07/01/2011-14981/review-of-new-sources-and-modifications-in-indian-country.
---------------------------------------------------------------------------

While the final Indian Country Minor NSR rule contemplated issuance
of general permits by the EPA regions, we have determined (for the
permits on which we are taking comment here) that a nationwide action
is appropriate. Through this action, we are proposing to issue general
permits to serve as preconstruction permit authorizations that contain
emission limitations and other restrictions to govern how a source may
construct, modify and operate. National general permits streamline the
permit issuance process by establishing universal requirements through
one notice for specific types of emissions activities at multiple
sources across the country. The EPA believes that the general permit
approach is appropriate for the source categories in today's proposal
where the control equipment or techniques are generally similar from
region to region.
A general permit also allows a reviewing authority to notify the
public through one notice that it intends to apply these requirements
to any eligible source that seeks coverage under the permit in the
future. This minimizes the burden on reviewing authorities' resources
by eliminating the need to issue separate permits for each individual
minor source within the source type or category covered by the general
permit. Use of a general permit also decreases the time required for an
individual minor source to obtain a preconstruction permit because the
application process is standardized.
The Indian Country Minor NSR rule describes the process the EPA
will use to issue general permits for the minor NSR program. A general
permit must be issued in accordance with the requirements in 40 CFR
49.156. Briefly, these requirements address public availability of
information, public notification and participation, and public
comments. In addition, as discussed in Section IX., we are providing
implementation tools to guide sources through a series of questions to
determine whether they meet the criteria to be eligible for coverage
under a general permit.

C. What is a permit by rule?

Like a general permit, a permit by rule is a standard set of
requirements that can apply to multiple stationary sources with similar
emissions characteristics. For purposes of this action, a permit by
rule would differ from a general permit in that the agency would codify
a permit by rule directly into the Indian Country Minor NSR rule. The
process for a source to apply for coverage under a permit by rule, and
the process for the reviewing authority to grant coverage under a
permit by rule, is more streamlined compared to a standard general
permit, or a site-specific permit. In particular, a proposed project
need not wait for a response from the permitting authority before
starting construction under a permit by rule. Section VII. provides a
description of the source application process for permits by rule.

IV. Description of General Permit Program in Indian Country and the
EPA's Use of This Package To Satisfy the General Permit Issuance
Process

A. General Permit Program

The EPA codified the framework it would follow to issue general
permits for minor sources in the Indian Country Minor NSR rule in 40
CFR 49.156. While it was not necessary for the EPA to codify this
framework to issue general permits, the EPA nonetheless created the
regulatory framework to better inform the public of the process the EPA
will use to issue general permits. Per the framework, to issue a
general permit, the reviewing authority must follow the requirements
for public participation contained in 40 CFR 49.157. These provisions
require the reviewing authority then to provide a notice that a draft
permit is available for comment. The regulations list a number of ways
in which a reviewing authority can provide notice to the public, and
also allow the reviewing authority to use other means of notification
as appropriate (40 CFR 49.157(b)(1)(ii)(E)). We have opted to provide
notice to the public regarding the present proposal of general permits
for six source categories through use of the Federal Register. We
believe this approach is appropriate in this case because we intend to
apply these general permits in all areas of Indian country subject to
the Indian Country Minor NSR Program and the Federal Register provides
a nationwide circulation of the notice. We will also mail a copy of
each permit for which the reviewing authority has approved coverage for
a source to the appropriate Indian governing bodies and the tribal,
state and local air pollution agencies in adjacent air jurisdictions
that may be impacted by the air pollution sources that use the general
permit in accordance with 40 CFR 49.157(b)(1)(i).
The existing regulations also identify the type of information that
a reviewing authority must make available to the public, and list a
number of elements to be included in the public notice (40 CFR
49.157(a) and (b)(2)). We are satisfying these requirements in this
proposal in a wide-ranging manner by providing the public access to the
application forms we will require an applicant to complete, and the
other implementation tools for each general permit. (We discuss these
tools in greater detail in Section IX. of this preamble.) Many of these
requirements relate to information that is best made available when an
individual applicant applies for coverage under a specific general
permit. We will make information specific to an individual source's
request for coverage under a general permit available at the time we
provide notice of the source's request for coverage.
After providing adequate public notice of the availability of the
draft permit, the reviewing authority must allow a period of at least
30 days for the public to comment on the permit, and to request a
public hearing (40 CFR 49.157). We are satisfying these requirements by
using this proposed rule to propose, take comments and hold a public
hearing on the general permits. Once we finalize a general permit, it
will be used by the EPA's regional office reviewing authorities \15\
for sources requesting coverage under the permit.
---------------------------------------------------------------------------

\15\ The Administrator delegated the authority to each of the
EPA Regional Administrators to carry out all aspects of the Indian
Country Minor NSR program, including issuing general permits and
approving individual coverage under a general permit.
---------------------------------------------------------------------------

The regulations set forth the provisions for a final permit to
undergo administrative and judicial review in accordance with 40 CFR
49.159. The procedures governing appeals of NSR permits to the
Environmental Appeals Board will govern administrative review of these
general permits. Issuance of a general permit is a final agency action
with respect to all aspects of the general

[[Page 41853]]

permit except its applicability to an individual source. The provisions
of 40 CFR 49.159 will continue to govern administrative and judicial
review of the EPA's approval of an individual source's request for
coverage. After the reviewing authority approves a request for coverage
by an individual source, a party may appeal only the applicability of
the general permit to that particular source.
Although we are using a Federal Register notice to initially
establish the general permits, we intend to use other methods also
consistent with procedures in 40 CFR 49.159 to reopen or
administratively amend the final permits if we determine it is
necessary and appropriate. A reviewing authority may reopen and revise
a final general permit for cause after providing the opportunity for
notice and comment under 40 CFR 49.157. Revisions to a final general
permit may be appropriate, for example, when the reviewing authority
decides to issue a new general permit for the same category to account
for advances in control technology or for other pertinent reasons.
However, when a reviewing authority issues a new general permit,
sources operating under the existing general permit will be able to
continue to operate under the existing permit unless and until the
source subsequently proposes to modify.\16\
---------------------------------------------------------------------------

\16\ If the EPA revises an existing general permit, then the
original permit can no longer be used for new and modified minor
sources. The new general permit will be used for new and modified
minor sources in the relevant source category. The existing general
permit remains in place for existing facilities unless and until
they choose to modify.
---------------------------------------------------------------------------

B. How do sources apply for general permits?

40 CFR 49.156(e) describes the procedure for sources to obtain
coverage under a general permit. At the time a source submits a request
for coverage under a general permit, it must submit a copy of such
request to the appropriate Indian governing body for the area of Indian
country where the source is locating. The reviewing authority must act
on the source's request for coverage under the general permit as
expeditiously as possible, but it must notify the source of the final
decision within 90 days of its receipt of the coverage request. The
source's reviewing authority must comply with a 45-day completeness
review period to determine if the request for coverage under a general
permit is complete. Therefore, within 30 days after the receipt of the
source's coverage request, the reviewing authority must make an initial
request for any additional information necessary to process the
coverage request and the source must submit such information within 15
days. If the source does not submit the requested information within 15
days from the request for additional information and this results in a
delay that is beyond the 45-day completeness review period, the 90-day
permit issuance period for the general permit will be extended by the
additional days the source takes to submit the requested information
beyond the 45-day period. If the reviewing authority fails to notify
the source within a 30-day period of any additional information
necessary to process the source's coverage request, the source will
still have 15 days to submit such information and the reviewing
authority must still grant or deny the request for coverage under a
general permit within the 90-day general permit issuance period and
without any time extension.
If the reviewing authority determines that the source's request for
coverage under a general permit has all the relevant information and is
complete, it will notify the source in writing as soon as that
determination is made. If the source does not receive from the
reviewing authority a request for additional information or a notice
that the request for coverage under a general permit is complete within
the 45-day completeness review period, the request will be deemed
complete.
After permit coverage is granted, under 40 CFR 49.156(e), coverage
under a general permit becomes invalid if a source does not commence
construction within 18 months after the effective date of coverage
under a general permit, if the source discontinues construction for a
period of 18 months or more, or if the source does not complete
construction within a reasonable time. The reviewing authority may
extend the 18-month period upon a satisfactory showing that an
extension is justified, and the 18-month limit does not apply to the
time period between construction of the approved phases of a phased
construction project. In those cases, construction of each such phase
must commence within 18 months of the projected and approved
commencement date.
In Section XI., the EPA proposes to amend 40 CFR 49.156(e) to
shorten the permit application procedure to 45 from 90 days for one
source category in today's proposal: Graphic arts and printing
operations.
In Section IX., we describe the implementation documents and tools
that we are making available for comment to assist sources with
applying for general permits.

C. What are the required permitting elements?

For general permits, these elements are discussed in the Indian
Country Minor NSR rule promulgated at 40 CFR 49.155(a) and include:
The effective date of the permit and the date by which a
source must commence construction in order for the permit's coverage to
remain valid (i.e., 18 months after the source obtains coverage under
the general permit);
The emissions units subject to the permit and their
associated emission limitations (and other permit conditions);
Monitoring, recordkeeping, reporting and testing
requirements to ensure compliance with the emission limitations; and
A severability clause to ensure the continued validity of
the other portions of the permit in the event of a challenge to a
portion of the permit.

V. Source Categories for Which Proposed General Permits in Indian
Country Are Available for Public Review

A. Notice of Proposed General Permits

In accordance with 40 CFR 49.171(b)(1)(1)(E), we are providing the
public with a copy of six proposed general permits covering six source
categories: (1) Concrete batch plants, (2) boilers, (3) stationary
spark ignition engines, (4) stationary compression ignition engines,
(5) graphic arts and printing operations and (6) sawmills. Copies of
each of these proposed permits and the following four associated
permitting documents are available in the docket for this notice (EPA-
HQ-OAR-2011-0151) and at https://www.epa.gov/air/tribal/tribalnsr.html:
(1) Request for Coverage (Application);
(2) Questionnaire;
(3) Instructions; and
(4) PTE calculator.
The application for one of the six source categories in today's
proposal (i.e., graphic arts and printing operations) is streamlined
and asks for contact and location information and basic solvent usage
information (more detailed source-specific information would be
required from sources seeking coverage under the other five general
permits). This is discussed further in Section IX.
The general permits will authorize \17\ construction of, or any
modifications of,

[[Page 41854]]

any of the affected emission units, or pollutant emitting activities
named in the permit, at any proposed true minor source that meets the
permit's applicability requirements and eligibility statements, and for
which the reviewing authority approves coverage under the permit.
---------------------------------------------------------------------------

\17\ To be eligible for a proposed general permit in today's
action, the PTE of your facility, including all existing, new, and
modified emission units present at the facility, must be below the
major source thresholds for NSR.
---------------------------------------------------------------------------

We request comment on all aspects of the general permits and the
associated forms and documentation provided to assist the stationary
sources specified in the permits in complying with the Indian country
minor NSR preconstruction permitting and post-construction operating
requirements. In Section VIII., we propose, in the alternative, a
permit by rule for graphic arts and printing operations. Should we
decide to finalize a permit by rule for this category, then we may not
finalize the draft general permit for that category. Alternatively, we
may opt to finalize both permitting mechanisms for this source
category, and may tailor one of the permitting mechanisms to provide
authorization to construct or modify true minor sources (i.e., permit
by rule) and another to provide enforceable limitations to create
synthetic minor sources (i.e., general permit). We specifically request
comment on this ``hybrid'' approach (see Section XI. of the January 14,
2014 proposal \18\ for further discussion on the hybrid approach).

New Source Review Program in Indian Country,'' U.S. Environmental

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

For the six source categories in today's action, we are proposing
general permits as our preferred approach. We have crafted our proposal
to ensure air quality is protected and to provide more detailed or
streamlined approaches, as appropriate. For concrete batch plants,
boilers, stationary spark ignition engines, stationary compression
ignition engines and sawmills, the EPA is proposing (1) that we retain
the 90-day application review process provided in the Indian Country
NSR Rule; and (2) that we provide more detailed applications that are
appropriate for sources in these categories that involve multiple
pollutants where the reviewing authority needs to conduct a review to
evaluate whether an individual source meets the requirements in the
permit. However, we also recognize that a more streamlined approach may
be appropriate for other source categories with few pollutants of
concern and in which the operations are less complex. For graphic arts
and printing operations, the EPA is proposing to change the underlying
rule to provide a shorter application review period (see Section XI.)
and a shorter application (see Section IX.). The permit by rule
proposed as an alternative for this source category would take that
streamlining a step further (see Section VII.).
The remainder of this section outlines the general structure of
each of the proposed general permits, and requests comment on issues
that are common among the proposed general permits. Specifically, we
are requesting comment on:
(1) Whether the EPA's proposed approach of incorporating by
reference each reviewing authority's approval of a request for coverage
into the general permit is necessary and appropriate; and
(2) The appropriateness of proposed permit terms related to the
reviewing authority's ability to reopen, revise, or terminate an
individual approval of coverage under the general permit.
This section also describes the general process we undertook for
each of the control technology reviews required to establish the terms
and conditions of each proposed general permit, and requests comment on
our conclusions on several aspects of the control technology reviews.
Additional information and supporting analyses on each of these
proposed permits are located in the background documents. These
documents are available at Docket ID No. EPA-HQ-OAR-2011-0151 and
online at https://www.epa.gov/air/tribal/tribalnsr.html.

B. Structure of General Permits

Each proposed general permit contains a similar overall structure.
The cover page of each proposed permit contains general information on
the proposed permit. First, it briefly describes the applicability of
the permit to a particular source category or emissions activity the
general permit regulates in accordance with 40 CFR 49.156(d)(1). This
description varies for each of the proposed permits, depending on the
emissions activity covered by the proposed permit.
Second, the cover page limits eligibility for coverage under the
permit to true minor sources. We included this limitation to allow
permitting authorities the ability to process a permit application for
inherently larger sources using the more extended time periods the
Indian Country Minor NSR rule provides for case by case, site specific
review. We also include this limitation in the proposed permits to
remain consistent with our current policy that we will not allow
sources to use general permits to create synthetic minor sources.
We recognize, however, that limiting eligibility of these proposed
permits to only true minor sources could limit the number and types of
sources that could take advantage of the streamlined, general
permitting process. In our prior proposal of January 14, 2014, we
proposed to change the current policy in the Indian Country Minor NSR
rule to allow general permits and permits by rule to create synthetic
minor sources. Depending on the outcome of that proposal, we may amend
one or more of the final permits in this proposal to allow any minor
source to apply for coverage under that permit.
Third, following the eligibility statement, the proposed permit
directs applicants to the specific information that an applicant must
include in a request for coverage under the permit in accordance with
40 CFR 49.156(d)(2)(ii) and (iii). The request for coverage serves as
the permit application and some of the information in the application
will differ for each proposed permit. We discuss the application and
implementation tools to assist true minor sources in determining
whether a source is eligible for coverage under a general permit in
Section IX.
Fourth, the proposed permit contains a statement that incorporates
each reviewing authority's approval of a request for coverage into the
general permit. Sections 1 through 6 of the general permit, and the
most current approval of the request for coverage, must be posted
prominently at the facility, and each affected emissions unit and any
associated air pollution control technology must be labeled with the
identification number listed in the Approval of the Request for
Coverage for that permitted source. We request comment on the inclusion
of this condition in the permits given that the Indian Country Minor
NSR rule only requires posting of the approval of coverage.
As we developed the proposed permits, we envisioned situations in
which the reviewing authority may need to revise information contained
in the approval notice sometime after issuance. For example, a source
covered by a general permit may subsequently change ownership. A
reviewing authority may delegate responsibilities for the general
permit to a tribal air pollution control agency. A source may
subsequently need to revise something in its request for coverage that
would

[[Page 41855]]

alter elements of the approval. For example, a source may misidentify
an equipment identification number in its request for coverage, or
decide to expand or limit the scope of the modification. A reviewing
authority may need to alter its approval of the request for coverage
for these situations. The general permit provisions at 40 CFR
51.156(b)(2) broadly reference 40 CFR 49.159, which specifically
addresses the reviewing authority's ability to reopen or
administratively amend permits. The provisions, however, do not
specifically delineate how they apply to an approval of a request for
coverage under a general permit. By incorporating the approval into the
general permit, we ensure that the revision procedures contained in 40
CFR 49.159 apply to revisions a reviewing authority may make to the
approval of the request for coverage. We request comment on this
approach for incorporating the approval of the request for coverage
into the general permit. Alternatively, we request comment on whether
such incorporation is unnecessary and on whether to apply the
procedures in 40 CFR 49.159 to the approval of the request for
coverage, or whether the EPA should amend the existing regulations at
40 CFR 49.156 to address amendments to the request for coverage.
Fifth, the proposed permit contains information on the reviewing
authority's right to terminate or revise the general permit. The
general permit provisions in the Indian Country Minor NSR rule provide
the reviewing authority the ability to revise, revoke and reissue, or
terminate a general permit. In harmony with those provisions, the
proposed permits include authority for a reviewing authority to revise
or terminate an approval of a request for coverage. We are adding these
provisions to the general permit, under the authority of 40 CFR
49.156(d), to clarify how the Indian Country Minor NSR rule intended
these provisions to apply to an individual request for coverage. We
request comment on inclusion of these provisions in the general permit,
or, alternatively, whether the EPA should amend the Indian Country
Minor NSR rule to expressly delineate the reviewing authority's right
to revise or terminate an individual source's coverage under a general
permit.
Finally, the proposed permit contains a statement indicating that
the definitions contained in the Indian Country Minor NSR rule govern
use of those terms within the general permit. The statement also refers
permittees to a section of the permit that contains definitions that
may be specific to the source categories or emissions activities
covered by the general permit; and indicates that when a term is not
otherwise defined we will interpret that term consistent with normal
business use. We, nonetheless, request comment on whether we should
include any additional definitions to improve the clarity of the
general permits.
Following the general information section, each proposed permit
contains the enforceable terms and conditions of the general permit.
Section 1 of the Terms and Conditions provisions contains general
provisions that, with only a few exceptions, are similar for all the
general permits. These provisions contain statements that the Indian
Country Minor NSR rule requires in each permit pursuant to 40 CFR
49.155.
In each permit, the general provisions are followed by emission
limitations and other operational restrictions or specifications, and
monitoring, recordkeeping, and reporting requirements that are unique
to each of the permits. The notice and reporting requirements are
followed by a section outlining the reviewing authority's ability to
change the general permit, including the approval of the request for
coverage, a section on requesting coverage under the permit, and
attachments with abbreviations and acronyms, a list of definitions, and
a list of reviewing authorities and areas of coverage. Attachments to
the concrete batch plant and sawmill permits also contain requirements
to minimize fugitive dust emissions. An attachment to the sawmill
permit contains sample VOC calculations. Attachments to the graphic
arts and printing operations general permit contain requirements for
serious, severe or extreme ozone nonattainment areas and sample
calculations for monthly VOC emissions.

C. The EPA's Control Technology Review

Each permit establishes specific numerical limitations on the
quantity, rate or concentration of emissions for each regulated NSR
pollutant emitted by each affected emissions unit. For each general
permit, in a manner similar to what a permitting authority would be
expected to do for an individual source, we established these control
technology-based requirements by researching both state and local air
quality programs to identify control technologies or other emissions
reduction measures used by similar sources in surrounding areas, and by
reviewing requirements contained in existing 40 CFR parts 60 and 63
emissions standards that apply to these source categories. Some of the
proposed permits build upon the requirements in the 40 CFR parts 60 and
63 emissions standards by including some control technology measures
found in state and local agencies' general permits for these source
categories. The proposed permit for graphic arts and printing
operations draws control information from control technique guidelines
for flexible package printing and offset lithographic printing
developed by the EPA covering activities in the printing industry.\19\
---------------------------------------------------------------------------

\19\ For more information, go to: https://www.epa.gov/glo/SIPToolkit/ctgs.html.
---------------------------------------------------------------------------

The background documents for each proposed permit explain the state
and local programs we reviewed to identify control technology options
in each source category. We believe that, because these control
measures are currently used by other similar sources in other areas of
the country, they are technically and economically feasible, and cost
effective. We request comment on this conclusion, and invite commenters
to submit specific information that would indicate that either: (1) The
measures in the proposed permits are not economically feasible and/or
cost effective; or (2) additional economically feasible and cost
effective measures are available and appropriate to include in the
final general permits.
In determining specific emission limitations and control measures
for each permit, we considered air quality conditions in Indian
country. Notably, Indian country contains both attainment and
nonattainment areas for different regulated NSR pollutants.\20\ In some
cases, for areas designated as nonattainment for a given pollutant, the
proposed permits contain more stringent emission limitations for that
pollutant (or precursors of that pollutant). These control requirements
will help mitigate any further degradation of air quality in those
areas. In other cases, however, the proposed permits do not include
different emission limitations based on the attainment status of the
area. In these situations, we determined that the emission limitations
are sufficient to protect air quality in both attainment and
nonattainment areas.
---------------------------------------------------------------------------

\20\ Maps for those NAAQS for which the EPA has designated
nonattainment areas in Indian Country are available online at https://www.epa.gov/air/tribal/tribalnsr.html and Docket ID No. EPA-HQ-OAR-
2011-0151. NAAQS for which the EPA has designated nonattainment
areas are: Ozone (2008 NAAQS), PM10 (1987 NAAQS),
PM2.5 24-Hour (2006 NAAQS), and PM2.5 Annual
(1997 NAAQS). There are no tribal lands in nonattainment for
SO2 (2010 NAAQS), NO2, lead (2008 NAAQS), and
CO.
---------------------------------------------------------------------------

For concrete batch plants, boilers, stationary spark ignition
engines, stationary compression ignition engines,

[[Page 41856]]

and sawmills, we also added additional provisions related to the
location of the emitting activities and the source property boundary.
We call these provisions, which are designed to minimize the impacts of
emissions on air quality in the immediate vicinity of the source,
setback requirements. Under the setback requirement, sources may not
locate within a specific distance from the property boundary and
nearest residences. In reviewing state and local air agency general
permits, we found that permitting authorities in Alaska, Texas and
Washington include setback requirements to protect local ambient air
quality from potential source impacts. We find that these requirements
are both reasonable and prudent measures to protect local air quality,
and are economically feasible and cost effective. We, therefore,
included similar measures in the proposed permits. We discuss the
specific setback requirements for each category in Section VI.
We welcome comments on the use of these setback requirements. We
also welcome comments on the types of buildings from which we should
establish setback requirements (e.g., schools, nursing homes). We
further request comment on whether the setback requirement conflicts
with tribal authority over zoning-related matters, and, if so, then on
how we should resolve that conflict.
To further protect against adverse local air quality impacts, the
proposed permits ensure that no source will cause or contribute to
NAAQS or PSD increment violations by prohibiting emissions that would
result in such impacts. Thus, reviewing authorities will consider any
air quality concerns unique to specific areas that arise after issuance
of the general permits in this proposal when determining whether an
individual permit applicant is eligible for coverage under the general
permit. For example, if a source wants to locate in an area with air
quality levels approaching or violating the NAAQS, the reviewing
authority may need to request that a source apply for a site-specific
permit so that the potential for greater control than that afforded by
the general permit can be evaluated.
In conducting the control technology review, we also considered the
anticipated growth rate of the source categories. In general, we do not
anticipate significant increases in growth for these six source
categories for the foreseeable future, as we identified no information
indicating that to be the case.\21\ Thus, we do not believe that
emissions increases from these categories will pose unique or
additional impacts on air quality in the foreseeable future that might
warrant a more stringent approach to controlling emissions than
contained in the proposed permits. We request comment on our conclusion
about anticipated growth in these source categories and regions, and
the reasonableness of the emission limitations and control measures
specified in the proposed permits.

Stoneman, Policy Advisor, EPA/OAQPS, March 13, 2014.
---------------------------------------------------------------------------

D. Scope of Coverage Under Each General Permit

In the Indian Country Minor NSR rule, the EPA stated that it may
use the general permit mechanism to issue permits to ``similar'' types
of emissions units or minor sources. This limitation on the ability to
issue general permits is consistent with the EPA's longstanding
interpretation of the CAA as it relates to the ability of a permitting
agency and source to use standardized protocols to meet CAA minor
source permitting requirements. The proposed general permits meet the
limitation that general permits apply only to similar sources, because
each of the permits covers only affected emission units or emissions
generating activities that are: (1) Specifically identified by name in
the permit; (2) generate the same regulated NSR pollutants in the same
manner and magnitude; and (3) are associated only with operations
within a defined source category.\22\ We discuss the specific scope of
each proposed general permit in more detail in Section VI. below and in
the background document for each proposed general permit.
---------------------------------------------------------------------------

\22\ These criteria are not the sole manner for demonstrating
that a general permit applies only to similar sources, but they
serve as examples of the types of characteristics that may be
relevant.
---------------------------------------------------------------------------

E. Surrogate Annual Allowable Emission Limitations

The Indian Country Minor NSR rule requires the reviewing authority
to establish annual allowable emission limitations for each affected
emissions unit and for each NSR regulated pollutant emitted by the
unit, if the unit is issued an enforceable limitation lower than the
PTE of that unit (40 CFR 49.155(a)(2)). For the six source categories
in this proposal, the proposed general permits provide emissions
limitations as annual tpy allowable emission limitations, throughput
limits or input-based emissions limits, or some combination thereof,
depending on the particular source category. In the case of concrete
batch plants, we believe that a production limit serves as a reasonable
surrogate for a tpy emission limitation, since there is a direct
correlation between the amount of material processed and the amount of
pollution emitted. We also believe that monitoring throughput rather
than actual emissions may provide a more cost-effective method of
demonstrating compliance. For example, concrete batch facilities
regularly track a facility's throughput, but do not necessarily analyze
specific emissions discharges. Thus, reliance on throughput limits
provides a more cost-effective approach to regulating emissions and we
believe this will enhance the potential for compliance with the
proposed permit for this category.
The approach for engines (spark ignition and compression ignition)
and boilers also relies on a concept of ``surrogate'' emissions
limitations, but instead of using throughput limits, these permits rely
on ``surrogate'' capacity limits. The capacity limits are set at levels
to ensure that the sources remain below certain tpy emissions rates. We
also believe that setting capacity limits rather than limitations on
actual emissions may provide a more cost-effective and practical method
of demonstrating compliance, which will enhance the potential for
compliance with the proposed permit for this category.
For sawmills and graphic arts and printing operations, we provide
tpy emissions limitations in the permit. We require sources in these
two categories to track throughput and to calculate annual emissions
based on their throughput using the calculator we have provided. The
reason for providing this additional flexibility for the source is due
to the uncertainty they face as to the exact nature of their production
at the start of a reporting period. For example, a sawmill will not
necessarily know what species of wood (each with different VOC content)
it will process in a given year. The source, therefore, would need to
track its board-feet throughput of each wood species and calculate the
emissions associated with the wood species to ensure it stays within
the permitted emissions limitations. The same approach is applicable to
graphic arts and printing operations that may be engaged in several
different types of printing operations that involve different solvents
with different VOC contents. Those sources need similar flexibility

[[Page 41857]]

and would also need to track solvent usage and VOC content to ensure
they stay within the permitted emissions limitations.
In Section VI. below, we request comment on these approaches for
the six source categories.
In a related matter, in the January 14, 2014, proposal, we
indicated that we granted reconsideration on the issue of allowing
reviewing authorities to use general permits to create synthetic minor
sources and proposed to change the current policy of not allowing their
use for this purpose. If the EPA allows otherwise major sources to
qualify as synthetic minor sources through use of general permits, we
request comment on specific changes that we would need to include in
the limits of each permit to properly regulate synthetic minor sources
for the six categories in this proposal. For example, should the EPA
establish higher annual tpy allowable emission limitations or surrogate
production limits that are just below the major source thresholds for
each regulated NSR pollutant, or should the EPA maintain the
limitations in the current proposed permits to maintain an adequate
compliance margin?

F. Requirements of the Endangered Species Act and the National Historic
Preservation Act \23\
---------------------------------------------------------------------------

\23\ These requirements apply to both general permits and
permits by rule. Only general permits are mentioned here but the
requirements apply identically to both permit types. Section VII.C.
is specific to permits by rule and notes that these requirements
also apply to permits by rule.
---------------------------------------------------------------------------

The ESA requires federal agencies to ensure, in consultation with
the U.S. Fish and Wildlife Service and/or the National Marine Fisheries
Service (the Services), that any action they authorize, fund, or carry
out will not likely jeopardize the continued existence of any listed
threatened or endangered species, or destroy or adversely modify the
designated critical habitat of such species. Under relevant ESA
implementing regulations, federal agencies consult with the Service(s)
on actions that may affect listed species or designated critical
habitat.
The NHPA requires federal agencies to take into account the effects
of their undertakings on historic properties (i.e., properties that are
either listed on, or eligible for listing on, the National Register of
Historic Places) and to provide the Advisory Council on Historic
Preservation (the Council) a reasonable opportunity to comment on such
undertakings. Under relevant NHPA implementing regulations, NHPA
consultations are generally conducted with the appropriate Tribal and/
or State Historic Preservation Officers in the first instance, with
opportunities for direct Council involvement in appropriate
circumstances, including, for example, consultations in connection with
undertakings affecting multiple tribes or states.
The Indian country minor NSR program has increased the number of
activities for which the EPA is the permitting authority. To meet ESA
and NHPA requirements, we have developed a process for compliance with
these laws when issuing the general permits. The EPA intends to consult
with the Services and the Council on our general permits and the
proposed procedures to address potential effects on relevant protected
resources.
For purposes of general permits, the EPA intends to adopt a
framework that provides appropriate protection for listed species and
critical habitat and historic properties. The EPA believes, based on
the evaluation of available information, that the sources that are the
subject of this proposal are unlikely to present a significant risk to
listed species and critical habitat and to historic properties because
they are by their nature small, low emitting sources. However, to
ensure listed species and critical habitats and historic properties are
protected, the EPA has developed a framework in the general permits
that requires the applicant to identify and assess effects before a
request for coverage under the general permit is submitted to the EPA.
(As noted below, the applicant must submit the assessment to the EPA as
part of the request for coverage.) Requiring this assessment should
help identify any concerns related to potential impacts on listed
species/critical habitat or historic properties early in the process
when the greatest opportunities to mitigate or avoid any impacts--
including changes to the facility's location or footprint--are
available. This framework is similar to procedures established by the
Office of Water for the National Pollutant Discharge Elimination System
General Permit for Stormwater Discharges from Construction
Activities.\24\ The EPA believes that requiring a process in the
general air quality permits that is similar to the already-established
process for the general stormwater permits will be beneficial for all
concerned: The applicants, the EPA, the tribes, and the Services.
---------------------------------------------------------------------------

\24\ ``Final National Pollutant Discharge Elimination System
(NPDES) General Permit for Stormwater Discharges from Construction
Activities,'' U.S. Environmental Protection Agency, February 29,
2012 (77 FR 12286), https://www.gpo.gov/fdsys/granule/FR-2012-02-29/2012-4822/content-detail.html.
---------------------------------------------------------------------------

The screening processes developed in the permits for both the ESA
and NHPA require the applicant to develop information about the
possible effects of the proposed new or modified facility, which
includes appropriate outreach to relevant expert resource agencies.
Such information and a certification regarding the outcome of the
applicant's screening procedures are submitted to the EPA as part of
the request for coverage under the general permit. This information is
included as an appendix to the applications for requests for coverage
under the general permits. The EPA will review this information as part
of determining whether a source is eligible for coverage under the
general permit. Because we have limited the applicability of the
general permits to categories of sources that have low emissions, we do
not expect they are likely to adversely affect listed species/critical
habitats, nor should they have potential effects on historic
properties. However, if, through the procedures required in the permit,
a source is determined to have an adverse effect on listed species/
critical habitats or potential effects on historic properties, the EPA
retains the authority to deny coverage under the general permit and to
proceed with source-specific permitting and consultation with the
appropriate resource agency(ies).

VI. Summary of Specific Terms and Conditions of the General Permits and
Request for Comment

In the following sections, we provide a brief summary of the source
category regulated by each general permit and the areas of each
proposed general permit on which we specifically seek public comment.
In this preamble, we are not delineating every aspect of the
requirements of the general permits. Instead, we refer readers to the
proposed permits and associated background information to review all of
the detailed requirements we include in each general permit. Although
we are soliciting comments on specific aspects of the proposed permits,
we, nonetheless, invite the public to comment on all relevant aspects
of the proposed permits.
Generally, we have designed the proposed permits to be as
comprehensive as possible and, thus, they contain emission limitations
requirements for several, potentially affected emission units that
could be found at a source. If a source determines that it does not
have all of the emission units that the general permit covers, it can
still seek coverage for those units

[[Page 41858]]

the permit covers. The intent of the comprehensive permit is to help
avoid sources with multiple emission units having to apply for multiple
general permits. In any case, if a source determines that it is does
not meet the qualifications of the general permit for a given category,
then it can apply for a site-specific permit.
We are proposing the general permits for true minor sources in
Indian country. To be eligible for a general permit as proposed in this
action, a source would need to calculate the PTE for all of its NSR-
regulated pollutants for all existing, new, and modified emission
units. If the total PTE is less than the NSR major source thresholds,
then the source is eligible for the permit, provided all other
qualifying conditions are satisfied.

A. Concrete Batch Plants

1. What is a concrete batch plant?
A concrete batch plant is an operation that combines various
ingredients to form concrete. Some of these inputs include sand, water,
aggregate (rocks, gravel, etc.), fly ash, potash, and cement. There are
two types of concrete batch plants: Ready mix plants and central mix
plants. A concrete plant can have a variety of parts and equipment,
including but not limited to: Mixers (either tilt-up or horizontal or
in some cases both), cement batchers, aggregate batchers, conveyors,
radial stackers, aggregate bins, cement bins, heaters, chillers, cement
silos, batch plant controls, and dust collectors (to minimize
environmental pollution).
Concrete is composed essentially of water, cement, sand (fine
aggregate) and coarse aggregate. Approximately 75 percent of the U.S.
concrete manufactured is produced at plants that store, convey, measure
and discharge these constituents into trucks for transport to a job
site. At most of these plants, sand, aggregate, cement and water are
all gravity fed from the weight hopper into the mixer trucks. The
concrete is mixed on the way to the site where the concrete is to be
poured. At some of these plants, the concrete may also be manufactured
in a central mix drum and transferred to a transport truck. Most of the
remaining concrete manufactured is cast as products in a factory
setting. Precast products range from concrete bricks and paving stones
to bridge girders, structural components, and panels for cladding.
Concrete masonry, another type of manufactured concrete, may be best
known for its conventional 8 x 8 x 16-inch block. In a few cases
concrete is dry batched or prepared at a building construction site.
Raw materials for concrete batch operations can be delivered to a
plant by rail, truck or barge. The cement is transferred to elevated
storage silos pneumatically or by bucket elevator. The sand and coarse
aggregate are transferred to elevated bins by front end loader,
clamshell crane, belt conveyor, or bucket elevator. From these elevated
bins, the constituents are fed by gravity or screw conveyor to weigh
hoppers, which combine the proper amounts of each material.
PM, consisting primarily of cement and pozzolan dust, but including
some aggregate and sand dust emissions, is the primary pollutant of
concern. In addition, there are emissions of metals that are associated
with this PM. All but one of the emission points is fugitive in nature.
The only point sources are the transfer of cement and pozzolan material
to silos, and these are usually vented to a fabric filter or ``sock.''
Fugitive sources include the transfer of sand and aggregate, truck
loading, mixer loading, vehicle traffic, and wind erosion from sand and
aggregate storage piles. The amount of fugitive emissions generated
during the transfer of sand and aggregate depends primarily on the
surface moisture content of these materials.
The extent of fugitive emissions control varies widely from plant
to plant. Types of controls used may include water sprays, enclosures,
hoods, curtains, shrouds, movable and telescoping chutes, central duct
collection systems, and the like. A major source of potential
emissions, the movement of heavy trucks over unpaved or dusty surfaces
in and around the plant, can be controlled by good maintenance and
wetting of road surfaces.\25\

2. What is in the proposed general air quality permit for new or
modified true minor source concrete batch plants?
This proposed general permit would apply to the construction of new
true minor source concrete batch plants or the modification of existing
true minor concrete batch plants located in Indian country. The
proposed permit is designed to be as comprehensive as possible and,
thus, contains emission limitations requirements for:
Storage silos;
Batch drop points;
Loading transfer areas;
Weigh hoppers;
Auxiliary storage bins;
Non-emergency stationary engines;
Emergency stationary engines; and
Setbacks.

The proposed permit requires that the permittee maintain and
operate each affected emission unit and any associated air pollution
control equipment, considering the manufacturer's recommended operating
procedures, so as to minimize emissions of NSR regulated pollutants.
The reviewing authority will determine whether the permittee is using
acceptable operating and maintenance procedures based on monitoring
results, opacity observations, review of operating and maintenance
procedures, and inspection of the permitted source. (Failure to meet
these requirements would constitute a violation of the permit.)
The proposed permit requires each storage silo to be equipped with
an audible alarm or an automatic shutoff system that warns when the
silo is full. Loading operations cannot be conducted without a warning
or shutoff device. Storage silos, weigh hoppers and auxiliary storage
bins must be vented to a fabric or cartridge filter. The filter systems
can be a centralized system. A suction shroud or other pickup device
should be installed at each batch drop point (drum, truck loading etc.)
and vented to a fabric or cartridge filter system. Loading and
unloading areas must be well lit during non-daylight hours when the
permitted source is in operation and visible emissions from each
storage silo, weigh hopper and auxiliary storage bin must not exceed 10
percent opacity based on a six-minute average (according to EPA Method
9 \26\). For portable and permanent concrete batch plants, the limit on
production is a maximum annual production rate of 2,000,000 cubic
yards. The proposed permit also requires a fugitive dust control plan.
---------------------------------------------------------------------------

From Stationary Sources, https://www.epa.gov/ttn/emc/promgate/m-09.pdf.
---------------------------------------------------------------------------

The proposed permit contains requirements for non-emergency and
emergency engines, in the event such engines are present at the
concrete batch plant. Non-emergency compression ignition engines
present at the site, excluding nonroad mobile engines, must comply with
the following:
Use diesel or biodiesel containing no more than 15 ppm
(0.0015 percent) sulfur;
Each compression ignition engine that commenced
construction on or after June 12, 2006 must be certified to the
applicable Tier standards in 40 CFR 89.112 and 40 CFR 1039.101 through
1039.104, for all pollutants, for the same

[[Page 41859]]

model year and maximum engine power; and
Each compression ignition engine that commenced
construction before June 12, 2006 shall meet certain standards as laid
out in the permit based on the engine's maximum rated power.
If the source includes one or more emergency engines, each
emergency engine must be equipped with a non-resettable hour meter and,
if using fuel oil, then it must use diesel or biodiesel containing no
more than 15 ppm (0.0015 percent) sulfur. Newer emergency engines--
model year 2006 or later for compression ignition engines and 2009 or
later for spark ignition engines--must meet certain certification or
emission requirements that are contained in the EPA emissions standards
at 40 CFR part 89, 40 CFR part 90, 40 CFR part 1048 or Table 1 to 40
CFR part 60, subpart JJJJ, as applicable. Other, older emergency
engines are required to meet certain routine maintenance requirements,
and must follow the manufacturer's emission-related operation and
maintenance instructions or the permittee must develop a maintenance
plan, which must provide, to the extent practicable, for the
maintenance and operation of the engine in a manner consistent with
good air pollution control practice for minimizing emissions.
The proposed general permit includes monitoring that is sufficient
to ensure compliance with the emission limitations that apply to the
source, including ensuring the fabric/cartridge filters are operating
properly, taking weekly opacity observations and fugitive emissions
surveys and meeting certain other requirements. The permit also
requires performance testing for emergency engines present at the plant
that must meet certain emissions standards, but are not certified by
the manufacturer to those standards and are not required to be
certified by the manufacturer. This requirement is needed since the EPA
certification program for certain engines is voluntary. The proposed
general permit includes recordkeeping and reporting sufficient to
ensure compliance with the monitoring requirements.
3. Request for Comment on the Proposed General Air Quality Permit for
New or Modified True Minor Source Concrete Batch Plants
We request comment on all aspects of the general permit for
concrete batch plants. We specifically request comment in the following
three areas:
a. Throughput Production Limit as a Surrogate for Annual Tons Per Year
Allowable Emission Limitations
The proposed concrete batch plant general permit contains a
throughput-based production limit that serves as a surrogate for annual
tpy allowable emission limitations. We discuss the use of surrogate
limits in Section V.E. above. For portable and permanent concrete batch
plants, as stated above, the limit on production is a maximum annual
production rate of 2,000,000 cubic yards.
The background information document for the proposed permit
contains the approximate tpy emission thresholds for which the
throughput limits act as surrogates. The proposed permit does not
establish different throughput limits based on the attainment status of
the area. We request comment on our use of throughput limits as a
surrogate for tpy emission limitations for this source category, and on
whether there should be different production throughput limits in
attainment and nonattainment areas.
In establishing specific limits for concrete batch facilities, we
considered whether we should compute the production throughput limits
on a tpy basis, or over a shorter period of time to ensure continuous
compliance. For concrete batch plants, where PM10 is the
limiting pollutant for non-fugitive emissions, we elected an annual
production limit to ensure annual compliance. We request comment on
whether we should instead establish a monthly total emission limitation
based on a 30-day rolling total or on any other appropriate averaging
period.
b. Setback Requirement
The proposed general permit requires concrete batch plants to
locate at least 150 feet from the nearest property boundary and 1,000
feet from the nearest residence. A number of states include setback
requirements in their general permits for this source category.\27\ We
believe that this requirement will minimize the impact of emissions
from these sources on localized air quality. We request comment on
whether we should include the setback requirement in the final permit
to provide additional protection against adverse impacts to localized
air quality. In addition, we request comment on whether there are other
neighboring types of buildings for which a setback should apply (e.g.,
schools, nursing homes) and whether to require owners/operators of
concrete batch plants subject to the permit to use physical markers on
their property to show compliance with the setback requirement.
---------------------------------------------------------------------------

\27\ Information on state setback provisions is available at:
Background Document: General Air Quality Permit for New or Modified
True Minor Source Concrete Batch Plants, Docket ID No. EPA-HQ-OAR-
2011-0151, https://www.epa.gov/air/tribal/tribalnsr.html.
---------------------------------------------------------------------------

c. Authorizing Multiple Locations
Concrete batch plants can operate as portable stationary sources. A
plant will locate in a single area for a specified period of time and
then disassemble and relocate to another area. We structured the
proposed general permit to accommodate relocation of a plant. A source
may identify multiple sites of operation in its request for coverage.
The reviewing authority will consider the request for each location,
and will specify approval of one or more of these locations in the
approval of the request for coverage. If the reviewing authority does
not approve a specific location, then the source will need to reapply
for coverage under the general permit or for a site specific permit
before relocating to this site. The general permit also requires a
source to submit a notification to the reviewing authority each time it
relocates to a pre-approved site. We request comment on the use of the
general permit to authorize relocation of a plant to pre-approved site
locations.

B. Boilers

1. What is a boiler?
A boiler is a device in which water typically is heated to provide
steam to drive turbines or engines, supply heat, or process materials.
This proposed permit covers steam generating units located at
institutional, commercial, and industrial facilities which combust non-
solid fossil fuels such as natural gas and fuel oil. This permit does
not cover boilers located at electric utilities or boilers used for the
burning of other fuels such as coal and wood. This source category does
not cover the manufacturers of boilers. The proposed General Air
Quality Permit for New or Modified True Minor Source Boilers only
covers new, true minor source boilers and modifications of existing
true minor source boilers.
Boilers designed to burn fuel oil primarily combust distillate oils
and residual oils.\28\ These boilers can be of water tube, fire tube,
cast iron, or tubeless design. Water tube boilers are used in a variety
of applications ranging from supplying large amounts of process steam
to providing space heat for

[[Page 41860]]

industrial facilities. In a water tube boiler, combustion heat is
transferred to water flowing through tubes which line the furnace walls
and boiler passes. The tube surfaces in the furnace (which houses the
burner flame) absorb heat primarily by radiation from the flames. The
tube surfaces in the boiler (adjacent to the primary furnace) absorb
heat primarily by convective heat transfer. Fire tube boilers are used
primarily for heating systems, industrial process steam generators, and
portable power boilers. In fire tube boilers, the hot combustion gases
flow through the tubes while the water being heated circulates outside
of the tubes. A cast iron boiler is one in which combustion gases rise
through a vertical heat exchanger and out through an exhaust duct.
Water in the heat exchanger tubes is heated as it moves upward through
the tubes. Cast iron boilers produce low pressure steam or hot water,
and generally burn oil or natural gas. They are used primarily in the
residential and commercial sectors. (Note that residential boilers are
not covered by the proposal.) Tubeless boilers incorporate nested
pressure vessels with water in between the shells. Combustion gases are
fired into the inner pressure vessel and are then sometimes
recirculated outside the second vessel.
---------------------------------------------------------------------------

\28\ AP-42, Chapter 1.3--Fuel Oil Combustion, https://www.epa.gov/ttnchie1/ap42/ch01/.
---------------------------------------------------------------------------

Natural gas combustion boilers are used to generate industrial
electric power, produce industrial process steam and heat, and heat
residential and commercial space.\29\ (Note that residential boilers
are not covered by the proposal.) Natural gas is generally more than 85
percent methane with varying amounts of ethane, propane, butane, and
inert gases (typically nitrogen, carbon dioxide (CO2), and
helium). Natural gas combustion boilers may be of water tube, fire
tube, or cast iron design. Water tube boilers can be distinguished
either as field erected units or packaged units; the former are built
onsite in either wall-fired or tangential-fired configurations and
generally have heat input levels exceeding 100 million British thermal
units (MMBtu)/hour, while the latter are shipped where needed, are
always wall-fired, and generally have heat input levels of less than
100 MMBtu/hour.
---------------------------------------------------------------------------

\29\ AP-42, Chapter 1.4--Natural Gas Combustion, https://www.epa.gov/ttnchie1/ap42/ch01/.
---------------------------------------------------------------------------

The emissions from fuel oil-fired boilers include PM,
SO2, NOX, CO, small amounts of VOCs, and trace
elements. The emissions from natural gas-fired boilers include
NOX, CO, CO2, nitrous oxide, VOCs, trace amounts
of SO2, and PM.
2. What is in the proposed General Air Quality Permit for New or
Modified True Minor Source Boilers?
This proposed general permit would apply in Indian country to the
construction of new, true minor source boilers and modifications of
existing true minor source boilers. The proposed permit is designed to
be as comprehensive as possible and, thus, contains requirements for:
Boiler capacity limits;
Emissions and opacity limitations;
Boiler stacks;
Fuel usage;
Setbacks; and
Emergency engines.
The proposed permit requires that the permittee maintain and
operate each affected emission unit and any associated air pollution
control equipment, considering the manufacturer's recommended operating
procedures, so as to minimize emissions of NSR regulated pollutants.
The reviewing authority will determine whether the permittee is using
acceptable operating and maintenance procedures based on monitoring
results, opacity observations, review of operating and maintenance
procedures, and inspection of the permitted source. (Failure to meet
these requirements would constitute a violation of the permit.)
The proposed permit uses boiler capacity limits as emissions
limitations. The permit provides a capacity limit for an individual
boiler located in an attainment or nonattainment area of less than 100
MMBtu/hour. Further, the proposed permit restricts capacity by laying
out a matrix of combined maximum rating capacity limits for different
fuel types (i.e., liquid, gaseous) by boiler size or type. The combined
capacity limits vary by area designation/classification. The combined
capacity limits are set at levels intended to ensure the covered
sources remain below major source levels.
The proposed permit also provides output-based and input-based
emission limitations for boilers rated at 10 MMBtu/hour or greater. The
proposed permit restricts fuel use to natural gas or fuel oil (i.e.,
diesel or biodiesel) with a sulfur content of 0.0015 percent or less by
weight. In addition, a natural gas unit may use fuel oil as a backup
emergency fuel for up to 500 hours per calendar year.
The proposed permit requires that the boiler(s) must not discharge
into the atmosphere any gases that exhibit 5 percent opacity or greater
averaged over any six-consecutive-minute period. The boiler stack(s)
must be above the buildings in the vicinity, discharge vertically, and
have no obstructions to gas flow such as rain caps, except for hinged
rain caps. Each boiler must undergo biennial tune-ups.
If the permittee is operating the boiler(s) in a severe or extreme
ozone nonattainment area, then the permittee must comply with
additional requirements. Boilers located in severe or extreme ozone
nonattainment areas must meet tighter emissions limitations for
NOX.
The proposed permit contains requirements for emergency engines
located at the same facility as a boiler. Each emergency engine must be
equipped with a non-resettable hour meter and, if using fuel oil, then
it must use diesel or biodiesel containing no more than 15 ppm (0.0015
percent) sulfur by weight. Newer emergency engines--model year 2006 or
later for compression ignition engines and 2009 or later for spark
ignition engines--must meet certain certification or emission
requirements that are specified in the EPA emissions standards at 40
CFR part 89, 40 CFR part 90 and 40 CFR part 1048 or Table 1 to 40 CFR
part 60, subpart JJJJ, as applicable. Older emergency engines are
required to meet certain routine maintenance requirements, and must
follow the manufacturer's emission-related operation and maintenance
instructions or the permittee must develop a maintenance plan, which
must provide, to the extent practicable, for the maintenance and
operation of the engine in a manner consistent with good air pollution
control practice for minimizing emissions.
The proposed permit includes monitoring that is sufficient to
ensure compliance with the emission limitations that apply to the
source, including visible emissions surveys and an initial and
additional periodic performance testing. The proposed permit also
requires performance testing for emergency engines located at the same
source that must meet certain emissions standards, but are neither
required to be certified by the manufacturer nor are certified by the
manufacturer as meeting those standards. The basis for this requirement
is the fact that the EPA certification program for certain engines is
voluntary. The proposed permit includes recordkeeping and reporting
sufficient to ensure compliance with the monitoring requirements.

[[Page 41861]]

3. Request for Comment on the Proposed General Air Quality Permit for
New or Modified True Minor Source Boilers
We request comment on all aspects of the general permit for
boilers. We specifically request comment in the following three areas:
a. Surrogate Annual Allowable Emission Limitations
The boilers general permit contains capacity limits that serve as
surrogate annual tpy allowable emission limitations. We discuss the use
of surrogate limits in detail in Section V.E. above. In addition, we
request comment on the use of these surrogate capacity limits. In lieu
of establishing surrogate limits, we request comment on whether,
instead of containing surrogate limits, the final permits should
contain tpy emission limitations and require the use of monitoring of
material use to demonstrate compliance. We also request comment on
finalizing two boiler general permits--one intended for smaller,
simpler sources that uses capacity limits and one for larger, more
complex sources that uses tpy emission limitations together with
additional monitoring and recordkeeping requirements. Other
requirements in the permits would be essentially the same. Finally, we
request comment on the appropriateness of establishing different
capacity limits based on the attainment status of the area and whether
the specified capacity limits should be lower in nonattainment areas
than attainment areas.
b. Should we establish different requirements for severe or extreme
ozone nonattainment areas?
The proposed general permit contains emissions limits for sources
that locate in severe or extreme ozone nonattainment areas. We request
comment on the need for these limits.
c. Setback Requirement
The proposed general permit requires the exhaust from each boiler
or heater to be located a minimum of 50 feet from the nearest property
line and 150 feet from any adjacent residential or commercial
establishment or place of public assembly. The EPA's 40 CFR parts 60,
61, and 63 regulations do not contain setback requirements affecting
boilers or heaters. However, certain states include setback
requirements in their general permits for certain source categories,
although not necessarily for boilers. We believe that these
requirements will minimize the impact of emissions from these sources
on localized air quality. These setbacks are less stringent than the
proposed setback permit provisions in the proposed concrete batch
plant, engine and sawmill permits. We believe a different (lesser)
setback requirement is warranted for the boilers general permit
compared to the other general permits because of the different type of
equipment associated with the stationary sources covered by this
proposed permit. This proposed permit would generally be used for
institutional, commercial, and small industrial operations which tend
to have less air impact. In addition, the boilers general permit
contains specific numerical limits on NOX and CO emissions
that will further limit air impacts.
We request comment on whether we should include these setback
requirements in the final permit to provide additional protection
against adverse impacts to local air quality. In addition, we request
comment on whether there are other neighboring types of buildings from
which the setback should apply (e.g., schools, nursing homes) and
whether to require owners/operators of the boilers subject to the
permit to use physical markers on their property to show compliance
with the setback requirements.

C. Stationary Compression Ignition and Spark Ignition Engines

1. What are compression ignition and spark ignition engines?
Engines covered by these proposed general permits \30\ are
stationary internal combustion engines (ICE or engine) that convert
heat energy into mechanical work and are not mobile. This source
category does not include combustion turbines or nonroad \31\ engines
(mobile ICE) such as those on forklifts, off-highway mobile cranes,
bulldozers, and lawnmowers. Stationary ICE include reciprocating ICE,
rotary ICE, and other ICE, except combustion turbines as noted above.
Engine manufacturers are not included in this source category. In
addition, these general permits only apply to engines located at true
minor sources.
---------------------------------------------------------------------------

\30\ The EPA is making available for comment two proposed
general permits: One for spark ignition internal combustion engines
and one for compression ignition internal combustion engines.
\31\ As defined in 40 CFR 1068.30, a nonroad engine is used to
propel a motor vehicle, aircraft, or a vehicle used solely for
competition.
---------------------------------------------------------------------------

The proposed general permits cover both stationary non-emergency
and emergency stationary ICE. Emergency stationary ICE include any
stationary internal combustion engine whose operation is limited to
emergency situations and for which testing and maintenance are
required. Examples include stationary ICE used to produce power for
critical networks or equipment (including power supplied to portions of
a facility) when electric power from the local utility (or the normal
power source, if the facility runs on its own power production) is
interrupted, or stationary ICE used to pump water in the case of fire,
flood, or other adverse event. Stationary ICE used to supply power to
an electric grid or that supply power as part of a financial
arrangement with another entity are not considered to be emergency
engines.\32\
---------------------------------------------------------------------------

\32\ The definitions for emergency and stationary engines are
adopted from the definitions in 40 CFR 60.4219.
---------------------------------------------------------------------------

There are two types of ICE: Spark ignition and compression
ignition. A spark ignition engine is a gasoline, natural gas, or any
other type of engine with a spark plug (or other sparking device) and
with operating characteristics significantly similar to the theoretical
Otto combustion cycle. Spark ignition engines usually use a throttle to
regulate intake air flow to control power during normal operation.
Dual-fuel engines in which a liquid fuel (typically diesel fuel) is
used for compression ignition ICE and a gaseous fuel (typically natural
gas) is used as the primary fuel at an annual average ratio of less
than 2 parts diesel fuel to 100 parts total fuel on an energy
equivalent basis are spark ignition engines. A compression ignition ICE
is defined as an engine that is not a spark ignition engine. These
engines are typically diesel engines where the heat generated from
compression is enough to initiate the combustion process, without
needing an external spark.\33\
---------------------------------------------------------------------------

\33\ The definitions for spark ignition and compression ignition
engines are adopted from the definitions in 40 CFR 60.4219.
---------------------------------------------------------------------------

Gasoline, diesel (No. 2 fuel oil), and natural gas are the three
primary fuels used for ICE. Most natural gas-fired reciprocating
engines are used in the natural gas industry at pipeline compressor and
storage stations and at gas processing plants.\34\ Gasoline and small
diesel ICE (with capacities equal to or less than 600 horsepower (hp))
are used in a wide variety of industrial applications such as
generators, pumps, and material handling equipment (such as conveyors).
Gasoline is used primarily for mobile and portable engines. Diesel fuel
oil is the most versatile fuel and is used in compression ignition
engines of all

[[Page 41862]]

sizes. Substantial differences in engine duty cycles exist.\35\
---------------------------------------------------------------------------

\34\ AP-42, Chapter 3.2--Natural Gas-fired Reciprocating
Engines, https://www.epa.gov/ttnchie1/ap42/ch03/.
\35\ AP-42, Chapter 3.3--Gasoline and Diesel Industrial Engines,
https://www.epa.gov/ttnchie1/ap42/ch03/.
---------------------------------------------------------------------------

Large stationary diesel ICE (with capacities greater than 600 hp)
are often used in oil and gas exploration and production. These
engines, in groups of 3 to 5, supply mechanical power to operate
drilling (rotary table), mud pumping, and hoisting equipment, and may
also operate pumps or auxiliary power generators. Another frequent
application of large stationary diesel ICE is electricity generation
for both base and standby service. Smaller uses include irrigation,
hoisting, and nuclear power plant emergency cooling water pump
operation.\36\
---------------------------------------------------------------------------

\36\ AP-42, Chapter 3.4--Large Stationary Diesel and All
Stationary Dual-fuel Engines, https://www.epa.gov/ttnchie1/ap42/ch03/
.
---------------------------------------------------------------------------

The primary criteria pollutants emitted by engines are
NOX, CO, and VOC. The formation of NOX is
exponentially related to combustion temperature in the engine cylinder.
The other pollutants, CO and VOC, are primarily the result of
incomplete combustion. PM emissions include trace amounts of metals,
non-combustible inorganic material, and condensible, semi-volatile
organics which result from volatized lubricating oil, engine wear, or
from products of incomplete combustion. Emissions of sulfur compounds,
mainly SO2, are directly related to the sulfur content of
the fuel.
Three generic control techniques have been developed for
reciprocating engines: Parametric controls (timing and operating at a
leaner air-to-fuel ratio); combustion modifications such as advanced
engine design for new sources or major modification to existing sources
(clean-burn cylinder head designs and pre-stratified charge combustion
for rich-burn engines); and post-combustion catalytic controls
installed on the engine exhaust system. Post-combustion catalytic
technologies include selective catalytic reduction, nonselective
catalytic reduction, and CO oxidation catalysts.\37\

Engines, https://www.epa.gov/ttnchie1/ap42/ch03/.
---------------------------------------------------------------------------

2. What is in the proposed General Air Quality Permits for New or
Modified True Minor Source Spark Ignition and Compression Ignition
Engines?
These two proposed general permits would apply to the construction
of new, true minor source stationary compression ignition and spark
ignition engines or the modification of existing, true minor source
engines located in Indian country. We created separate proposed general
permits, one for compression ignition engines and one for spark
ignition engines, because there are different requirements for each
type of engine. Both engine general permits cover emergency and non-
emergency engines. (Sources that only have emergency engines and also
intend to construct a boiler may want to consider the boiler general
permit, which allows for greater boiler and emergency engine capacity.)
However, we have written both proposed general permits to accommodate
emergency engines of both engine types because the emissions from
emergency engines are relatively small and we did not want a particular
source to not be able to qualify for the general permit if, for
example, they happen to have a small compression ignition emergency
engine at a source of non-emergency spark ignition engines. As a
result, the spark ignition engine general permit covers non-emergency
spark ignition engines, emergency spark ignition engines, and emergency
compression ignition engines. The compression ignition general permit
covers non-emergency compression ignition engines, emergency
compression ignition engines, and emergency spark ignition engines.
The proposed general permits for compression ignition and spark
ignition engines require that the permittee, considering the
manufacturer's recommended operating procedures, maintain and operate
each affected emission unit and any associated air pollution control
equipment so as to minimize emissions of NSR regulated pollutants. The
reviewing authority will determine whether the permittee is using
acceptable operating and maintenance procedures based on monitoring
results, opacity observations, review of operating and maintenance
procedures, and inspection of the permitted source. (Failure to meet
these requirements would constitute a violation of the permit.)
The proposed compression ignition general permit imposes different
requirements depending upon where the source chooses to locate or
modify and whether the engine is for emergency or non-emergency
purposes. The proposed permit contains a setback requirement. Each non-
emergency compression ignition engine must not be located less than 150
feet from the nearest property boundary and 1,000 feet from the nearest
residence.
The proposed compression ignition general permit contains two
options for meeting capacity limits for engines locating in ozone
attainment, unclassifiable or attainment/unclassifiable areas or ozone
marginal and moderate nonattainment areas. Option 1 allows for a source
to have greater non-emergency engine capacity (up to 3800 hp) if the
non-emergency engines are within a set of certain parameters, mainly
related to whether the engines are part of a generator set. These types
of engines must meet much more stringent emission limits, resulting in
fewer emissions, and, thus, the permit provides the ability to increase
the capacity limit. Option 2 allows for less capacity for non-emergency
engines (1900 hp) but does not require non-emergency engines to be
within the specific parameters in Option 1. The proposed permit also
contains an additional overall capacity limit for engines locating or
modifying in serious ozone nonattainment areas (1100 hp for non-
emergency engines and 750 hp for emergency engines) and does not allow
permit coverage for engines locating or modifying in severe or extreme
ozone nonattainment areas.
The capacity limits restrict the size of engines that would be
covered by the proposed general permit. The proposed capacity limits
serve as surrogate emissions limitations and are set at levels that
correspond to emission rates intended to ensure emissions from sources
covered by the general permit are below major source levels.
The proposed compression ignition permit also includes requirements
for auxiliary heaters present at the new or modified facility so that
the permittee would not need to seek a separate permit for that
emissions unit. For the auxiliary heaters, the permit provides capacity
limits which require that the combined maximum heat input of all
auxiliary heaters not be greater than 10 MMBtu/hour and they can only
burn natural gas. Non-emergency compression ignition engines can only
use distillate fuel (i.e., diesel or biodiesel) containing no more than
15 ppm (0.0015 percent) sulfur by weight. Each of the engines must be
model year 2014 or later and certified by the manufacturer to the
applicable standards in 40 CFR part 89 and the Tier 4 standards in 40
CFR 1039.101 through 1039.104, for all pollutants, for the same model
year and maximum engine power.
Under the proposed spark ignition general permit, spark ignition
engines must meet certain capacity limits intended to ensure the
sources operate as minor sources. The combined maximum engine power of
all non-emergency spark ignition engines at a single permitted source
location shall be no greater than 1750 hp. The combined maximum engine
power of all

[[Page 41863]]

emergency engines at a single permitted source location must be no
greater than 800 hp. Non-emergency spark ignition engines must comply
with the limitations and standards in 40 CFR part 1054, 40 CFR part
1048, or Table 1 to 40 CFR part 60, subpart JJJJ, as applicable. The
Permittee must operate and maintain each engine certified by the
manufacturer, and any associated control device, according to the
manufacturer's emission-related written instructions. Each natural gas-
fired engine may be operated using propane for a maximum of 100 hours
per year as an alternative fuel solely during emergency operations,
provided such records are kept.
The proposed spark ignition general permit also contains a setback
requirement. Each non-emergency spark ignition engine must not be
located less than 150 feet from the nearest property boundary and 1,000
feet from the nearest residence.
The proposed compression ignition and spark ignition permits
contain requirements for emergency engines located at the same source
as the boiler(s), in the event such engines are present at the same
facility as the boiler(s). Each emergency engine must be equipped with
a non-resettable hour meter and, if using fuel oil, then it must use
diesel or biodiesel containing no more than 15 ppm (0.0015 percent)
sulfur by weight. Newer emergency engines--model year 2006 or later for
compression ignition engines and 2009 or later for spark ignition
engines--must meet certain certification or emission requirements that
are specified in the EPA emissions standards at 40 CFR part 89, 40 CFR
part 90 and 40 CFR part 1048 or Table 1 to 40 CFR part 60, subpart
JJJJ, as applicable. Older emergency engines are required to meet
certain routine maintenance requirements, and must follow the
manufacturer's emission-related operation and maintenance instructions
or the permittee must develop a maintenance plan, which must provide,
to the extent practicable, for the maintenance and operation of the
engine in a manner consistent with good air pollution control practice
for minimizing emissions.
The proposed compression ignition and spark ignition permits
include monitoring that is sufficient to ensure compliance with the
emission limitations that apply to the covered ICE, including
requirements to monitor fuel use on a monthly basis for each engine and
to conduct performance tests for engines not certified by the
manufacturer. The proposed permits also require performance testing for
spark ignition emergency engines that must meet certain emissions
standards, but are neither required to be certified by the manufacturer
nor certified by the manufacturer to those standards and are not
required to be certified by the manufacturer. This requirement is
necessary because the EPA certification program for certain engines is
voluntary. The proposed spark ignition general permit also includes,
for each engine equipped with an air-to-fuel ratio controller, a
requirement for proper maintenance and operation of the engine and
emissions control device to ensure its smooth operation. The proposed
permits include recordkeeping and reporting requirements.
3. Request for Comment on the Proposed General Air Quality Permits for
New or Modified True Minor Source Spark Ignition and Compression
Ignition Engines
We request comment on all aspects of the proposed general permits
for engines. We specifically request comment in the following four
areas:
(a) The Use of Capacity Limits as Surrogate Annual Allowable Emission
Limitations
In addition to fuel sulfur content limits and output-based
limitations for auxiliary heaters, the EPA is proposing to use capacity
limits as surrogate annual allowable emission limitations for the
engines source category. The capacity limits are set at levels intended
to ensure that the engines operate as minor sources.\38\ We request
comment on the appropriateness of these capacity limits. We also
request comment on whether the required emissions limitations should be
expressed as capacity limits or in another form.
---------------------------------------------------------------------------

\38\ Information on the source of these capacity limits is
available at: Background Document: General Air Quality Permits for
New or Modified True Minor Source Compression Ignition and Spark
Ignition Engines, Docket ID No. EPA-HQ-OAR-2011-0151, https://www.epa.gov/air/tribal/tribalnsr.html.
---------------------------------------------------------------------------

(b) Setback Requirement
The proposed general permits require stationary spark ignition and
compression ignition engines to locate at least 150 feet from the
nearest property boundary and 1,000 feet from the nearest residence.
The EPA's 40 CFR parts 60, 61, and 63 regulations do not contain
setback requirements affecting these engines. However, certain states
include setback requirements in their general permits for certain
source categories, but not necessarily for engines alone. We believe
that it is prudent to propose a setback for engines due to the
potential for local scale air quality impacts due to NOX
emissions from compression ignition engines that can transform in the
atmosphere to nitrogen dioxide (NO2) and have local
NO2 impacts, as well as CO emissions from spark ignition
engines that can have local CO impacts. We believe that these
requirements will minimize the impact of emissions from these sources
on localized air quality. We request comment on whether we should
include these setback requirements in the final permits to provide
additional protection against adverse impacts to local air quality. In
addition, we request comment on whether there are other neighboring
types of buildings from which the setback should apply (e.g., schools,
nursing homes) and whether to require owners/operators of the engines
subject to the permit to use physical markers on their property to show
compliance with the setback requirements.
(c) Should we establish different requirements for compression ignition
engines locating or modifying in serious ozone nonattainment areas?
The proposed general permit for compression ignition engines
contains additional requirements for sources that locate or modify in
serious ozone nonattainment areas. These requirements consist of
overall capacity limits for non-emergency and emergency engines. We
added this requirement to provide extra air quality protection for
areas with poorer ozone air quality. We request comment on the need for
these enhanced requirements in serious ozone nonattainment areas.
(d) Should owners and operators seeking to locate compression ignition
engines in severe, and/or extreme ozone nonattainment areas (or to
modify engines already located in those areas) be allowed to use the
proposed general permit?
The proposed compression ignition general permit contains
requirements for engines locating or modifying in marginal, moderate
and serious ozone nonattainment areas. Engines locating or modifying in
severe or extreme ozone nonattainment areas are not eligible for
coverage under the proposed general permit. This is because the
appropriate capacity limits that EPA would set in order to keep an
engine from being a major NOX source in a severe or extreme
nonattainment would be too low to be viable. We request comment on
whether our reasoning here is sound and whether we should restrict
applicability of the proposed compression ignition engine general
permit to marginal,

[[Page 41864]]

moderate, and serious ozone nonattainment areas.

D. Graphic Arts and Printing Operations

1. What is a graphic arts and printing operation?
The term ``graphic arts'' as used here means four basic processes
of the printing industry: Web offset lithography, web letterpress,
rotogravure, and flexography.\39\ (Screen printing and manual sheet-fed
techniques are not included in this source category description.)
Printing may be performed on coated or uncoated paper and on other
surfaces, as in metal decorating and some fabric coating. The material
to receive the printing is called the substrate. The distinction
between printing and paper coating, both of which may employ
rotogravure or lithographic methods, is that printing invariably
involves the application of ink by a printing press, whereas paper
coating does not involve that process. Printing and paper coating do,
however, have these elements in common: Application of a relatively
high-solvent-content material to the surface of a moving web or film;
rapid solvent evaporation by movement of heated air across the wet
surface; and solvent-laden air exhausted from the system. Printing inks
vary widely in composition, but all consist of three major components:
Pigments, which produce the desired colors and are composed of finely
divided organic and inorganic materials; binders, the solid components
that lock the pigments to the substrate and are composed of organic
resins and polymers or, in some inks, oils and rosins; and solvents,
which dissolve or disperse the pigments and binders and are usually
composed of organic compounds. The binder and solvent make up the
``vehicle'' part of the ink. The solvent evaporates from the ink into
the atmosphere during the drying process.
---------------------------------------------------------------------------

\39\ AP-42, Chapter 4.9--AP-42, https://www.epa.gov/ttn/chief/ap42/ch04/.
---------------------------------------------------------------------------

VOCs are the primary pollutant of concern from printing operations.
Such emissions vary with the printing process, ink formulation and
coverage, press size and speed, and operating time. The type of paper
(coated or uncoated) has little effect on the quantity of emissions,
although low levels of VOC emissions are derived from the paper stock
during drying. Most of the solvent contained in the ink and used for
dampening and cleanup is eventually emitted into the atmosphere;
however, some solvent does remain with the printed product leaving the
plant and is released to the atmosphere later. Overall, VOC emissions
can be computed using a material balance concept, except in cases where
a direct flame dryer is used and some of the solvent is thermally
degraded.
2. What is in the proposed General Air Quality Permit for New or
Modified True Minor Source Graphic Arts and Printing Operations?
This proposed general permit would apply to the construction of
new, true minor source graphic arts and printing facilities or the
modification of existing, true minor source facilities, located in
Indian country.
The proposed permit requires that the permittee maintain and
operate each affected emission unit and any associated air pollution
control equipment, considering the manufacturer's recommended operating
procedures, so as to minimize emissions of NSR regulated pollutants.
The reviewing authority will determine whether the permittee is using
acceptable operating and maintenance procedures based on monitoring
results, review of operating and maintenance procedures, and inspection
of the permitted source. (Failure to meet these requirements would
constitute a violation of the permit.)
This proposed general permit is not available to sources that are
major sources of hazardous air pollutants (HAPs). Under section 112 of
the CAA, a source is considered major for HAPs if it emits 25 tpy or
more of any combination of HAPs or 10 tpy of any single HAP. We are
proposing that the general permit for this source category not be
applicable to a major source of HAPs because additional requirements
apply to these types of source and we believe the general permits
should be reserved for sources with straightforward permitting
requirements. We believe that permit applications for such major
sources should receive greater scrutiny than a general permit would
provide. We welcome comment on this issue.
The proposed permit requires that VOC emissions from an individual
printing press (i.e., printing line) not exceed 25 tpy. We included
this requirement to avoid the need for add-on control requirements. We
believe smaller printing presses (i.e., those that emit less than 25
tpy of VOC) do not warrant the need for add-on controls. Sources
applying for this permit that nevertheless intend to install add-on
controls would not be prohibited from obtaining this general permit,
but they would need to be able to demonstrate compliance with the
permit without the consideration of controls. Thus, this general permit
is only intended for smaller graphic arts and printing operations, as
larger operations would likely require more site-specific review and
add-on controls.
The proposed permit also requires that VOC emissions from the
combination of all graphic arts and printing operations (all printing
lines at the facility) not exceed certain tpy limitations that vary by
ozone area designation and classification. For nonattainment areas, the
numerical limitations become more stringent as the classification
increases from marginal to extreme.
For flexible packaging printing operations, the permit contains VOC
content limitations for each coating, ink or adhesive used. However,
the permit provides an exemption that allows up to 110 gallons per
calendar year of VOC-containing material to not meet the VOC content
limitations standards for graphic arts and printing operations located
in areas designated as ozone attainment, unclassifiable, attainment/
unclassifiable, marginal nonattainment, or moderate nonattainment. This
is to allow the use of a small amount of specialty coating, inks, or
adhesives.
For offset lithographic and letterpress printing operations, the
permit contains VOC limitations that vary depending upon the type of
printing operation. The permit provides limitations for heatset web
offset lithographic printing, sheet-fed offset lithographic printing
and coldset web offset lithographic printing. The permit provides an
exemption from VOC limitations for sheet-fed offset lithographic
printing operations that use sheet-fed presses with sheet sizes of 11
inches by 17 inches or smaller OR any press with a total fountain
solution reservoir of less than 1 gallon.
The permit provides additional VOC limits for permitted sources
that locate or modify in a serious, severe or extreme ozone
nonattainment area for the following materials:
Lithographic ink;
Letterpress ink;
Rotogravure ink;
Flexographic ink non-porous substrate;
Flexographic ink porous substrate;
Flexographic fluorescent ink;
Coating;
Adhesive; and
Fountain solution.

The permit requires that: (1) The VOC content of cleaning materials
used for cleaning operations not exceed 70 percent by weight; (2) all
VOC-containing material (e.g., inks, adhesives, coatings, thinners, and
clean-

[[Page 41865]]

up solvents) be stored in closed containers with labels that clearly
identify the contents of the container; and (3) all waste materials
containing VOC (e.g., soiled rags) be stored in sealed containers until
properly disposed.

The permittee must implement procedures to minimize spills of any
VOC-containing material during handling and transfer to and from
containers, enclosed systems, waste receptacles and other equipment.
The proposed permit contains requirements for new or modified
emergency engines, in the event such engines are present at the new or
modified graphic arts and printing facility. Each emergency engine must
be equipped with a non-resettable hour meter and, if using fuel oil,
then it must use diesel or biodiesel containing no more than 15 ppm
(0.0015 percent) sulfur by weight. Newer emergency engines--model year
2006 or later for compression ignition engines and 2009 or later for
spark ignition engines--must meet certain certification or emission
requirements that are contained in the EPA emissions standards at 40
CFR part 89, 40 CFR part 90 and 40 CFR part 1048 or Table 1 to 40 CFR
part 60, subpart JJJJ, as applicable. Other, older emergency engines at
the new or modified facility are required to meet certain routine
maintenance requirements, and must follow the manufacturer's emission-
related operation and maintenance instructions or the permittee must
develop and implement a maintenance plan, which must provide, to the
extent practicable, for the maintenance and operation of the engine in
a manner consistent with good air pollution control practice for
minimizing emissions.
The proposed permit includes monitoring that is sufficient to
ensure compliance with the emission limitations that apply to the
source. Compliance would include requiring monitoring the usage of VOC-
containing materials on a weekly basis and conducting performance
testing for emergency engines that are not required to be certified by
the manufacturer as meeting those standards and are not in fact so
certified. (This requirement is needed since the EPA certification
program for certain engines is voluntary.) The proposed permit includes
recordkeeping and reporting sufficient to ensure compliance with the
monitoring requirements.
3. Request for Comment on the Proposed General Air Quality Permit for
New or Modified True Minor Source Graphics Arts and Printing Operations
We request comment on all aspects of the proposed general permit
for graphic arts and printing operations. We specifically request
comment in the following two areas:
(a) Use of Tons Per Year Numbers as Emission Limitations
In addition to proposing limits on the VOC content of specified
materials, the EPA is also proposing to include annual allowable VOC
emission limitations for the graphic arts and printing operations
source category. The proposed general permit includes an upper emission
limitation of 25 tpy of VOC from an individual printing press (printing
line). The proposed permit also provides overall total tpy emissions
limitations for all printing lines at the facility, which become more
stringent as the classification of the relevant ozone nonattainment
area increases.\40\ Sources will need to monitor their material usage
and perform material balance calculations using the calculator we are
providing to ensure they are staying within these tpy limitations.
---------------------------------------------------------------------------

\40\ Information on these limitations is available at:
Background Document: General Air Quality Permit for True Minor
Source Graphics Arts and Printing Operations, Docket ID No. EPA-HQ-
OAR-2011-0151, https://www.epa.gov/air/tribal/tribalnsr.html.
---------------------------------------------------------------------------

We opted to not propose surrogate throughput limits for graphic
arts and printing operations, as we have for one other source category,
because of the diversity of printing lines and materials that a
facility may employ. It would be very difficult to set a material usage
throughput limit that would have broad applicability. In addition,
providing actual emissions limitations directly in the permit ensures
the protection of air quality, while at the same time providing the
source with flexibility regarding the types of printing lines and
materials they use. We request comment both on the appropriateness of
establishing annual VOC emissions limitations in the permit (versus
throughput limits) and on whether the proposed limitations are set at
the correct levels.
(b) Should we establish requirements that differ from those for
attainment, unclassifiable and attainment/unclassifiable areas for
marginal, moderate, serious, severe and extreme ozone nonattainment
areas?
The proposed permits contain additional requirements for sources
that locate in ozone nonattainment areas. First, the annual tpy
emissions limitations for VOC decline as the classification of ozone
nonattainment increases from marginal to extreme. The numbers are set
at levels intended to ensure that the sources are not major for HAPs or
for NSR purposes. Second, the proposed permit requires lower VOC
content levels for materials used at graphic arts and printing
operations located in severe or extreme ozone nonattainment areas. Both
of these features are meant to ensure that there is extra air quality
protection in ozone nonattainment areas with higher classifications. We
request comment on whether these additional limitations are needed and,
if so, whether they are set at the correct levels.

E. Sawmills

1. What is a sawmill facility?
A sawmill facility is an operation that processes raw timber into
dimensional lumber for shipping and eventual sale. A modern sawmill's
basic operation is much like those of hundreds of years ago; a log
enters at one end and dimensional lumber exits at the other end.
Sawmill activities include sawing, planing, sanding, chipping and
drying wood. Sawmill facilities are common in areas with ample supplies
of timber, including the southeast and northwest.
A sawmill's basic operation involves several steps to turn logs
into dimensional lumber:
Logs are brought in by logging truck, rail or a log drive
to the sawmill;
Logs are scaled either on the way to the mill or upon
arrival at the mill;
Debarking removes bark from the logs;
Decking is the process for sorting the logs by species,
size and end use (lumber, plywood, chips);
The head saw, head rig or primary saw, breaks the log into
cants (unfinished logs to be further processed) and flitches
(unfinished planks) with a smooth edge;
Depending upon the species and quality of the log, the
cants will be further broken down by either a resaw or a gang edger
into multiple flitches and/or boards;
Edging trims all irregular edges off of the flitch,
leaving four-sided lumber;
Trimming squares the ends at typical lumber lengths;
Drying removes naturally occurring moisture from the
lumber (this can be done with kilns or the lumber can be air-dried);
Planing smoothes the surface of the lumber leaving a
uniform width and thickness; and
Shipping transports the finished lumber to market.

[[Page 41866]]

Sawmills typically derive their power from the electric grid.
Dryers may be either direct-fired or indirect-heated. Boilers are
typically used to provide the heat for dryers. In direct-fired dryers,
hot combustion gases from an onsite boiler are blended with
recirculated exhaust from the dryer to lower the gas temperature to a
level that will not scorch the lumber. In indirect-heated dryers, air
is warmed over steam coils and then circulated over the lumber. Dryers
typically have one to three heated zones followed by a cooling zone or
section. Each heated zone has a hot air source, fans to move the warm
air, and an exhaust vent or stack. The cooling section circulates
ambient air over the wood to reduce the temperature just before it
exits the dryer. The lumber must be cooled before proceeding to the
next step in the process.
Criteria pollutant emissions of concern are primarily PM from
sawing and planing, but also include PM from re-entrained road dust or
sawdust particles; VOCs from drying; and NOX from boilers
and emergency diesel generators. PM control methods include water
sprays and dry control methods (baghouses, fabric filters and
cyclones).
2. What is in the proposed General Air Quality Permit for New or
Modified True Minor Source Sawmill Facilities?
This proposed general permit would apply to the construction of new
true minor source sawmills or the modification of existing true minor
source sawmills, located in Indian country. The proposed permit
requires that the permittee maintain and operate each affected emission
unit and any associated air pollution control equipment, considering
the manufacturer's recommended operating procedures, so as to minimize
emissions of NSR regulated pollutants. The reviewing authority will
determine whether the permittee is using acceptable operating and
maintenance procedures based on monitoring results, review of operating
and maintenance procedures, and inspection of the permitted source.
(Failure to meet these requirements would constitute a violation of the
permit.)
In creating the proposed sawmill general permit, the EPA considered
VOC emissions from kiln drying, surface coating operations, boilers,
and emergency engines. We are requesting comment on whether there are
other sources of VOC emissions at sawmills that should be included in
our analysis.
The proposed permit is designed to be as comprehensive as possible
and, thus, contains emission limitations requirements for the following
affected emission units or activities:
Planar mill operations (baghouse/fabric filter);
Sawmill operations (baghouse/fabric filter or cyclone);
Open burning (restrictions on);
Boilers;
Emergency engine use;
Fugitive dust control; and
Setbacks.
The proposed permit prohibits open burning and restricts the
burning and combustion of wood or lumber products to wood-fired
boilers. Each identified emissions unit must not result in the
discharge of any gases that exhibit 20 percent opacity or greater
averaged over any six-consecutive-minute period. Any liquid fuels used
at the facility shall contain no more than 0.0015 percent sulfur by
weight. The production of finished lumber is limited to 25 million
board feet per year based on a 12-month rolling total. The 12-month
rolling total is determined by the sum of the current monthly
production and the total of the previous 11 months' production. The
purpose of the board feet restriction is to further limit PM emissions
from sawmill operations. The limit is in addition to the requirement
that sawmills covered by the proposed general permit install cyclones
and/or baghouses/fabric filters. The requirement is consistent with the
general permits for sawmills in the states of Texas and Oregon.\41\
---------------------------------------------------------------------------

\41\ Information on board feet limitations is available at:
Background Document: General Air Quality Permit for New or Modified
True Minor Source Sawmill Facilities, Docket ID No. EPA-HQ-OAR-2011-
0151, https://www.epa.gov/air/tribal/tribalnsr.html.
---------------------------------------------------------------------------

In addition to requiring the installation and operation of air
pollution controls as described below, the proposed permit limits tpy
VOC emissions from all lumber drying kilns and surface coating
operations regardless of where the sawmill is planning to locate or
modify. The limitations for facilities planning to locate or modify in
ozone nonattainment areas are progressively more restrictive as the
classification of the ozone nonattainment area increases from marginal
to extreme. Planar mill operations must be conducted within enclosed
structures and a baghouse or fabric filter must be used to control
emissions to the atmosphere. Sawmill operations conducted outdoors
(i.e., operations other than planar mill operations) must, at a
minimum, be covered and all material handling operations must be
controlled using a cyclone or baghouse/fabric filter during all times
that the affected emission units operate. Emissions to the atmosphere
from sawmill operations conducted indoors must be controlled using a
baghouse or fabric filter. The permittee must develop and implement a
fugitive dust control plan. All VOC-containing material (e.g.,
coatings, thinners, and clean-up solvents) must be stored in closed
containers. All waste materials containing VOC (e.g., soiled rags) must
be stored in sealed containers until properly disposed.
The proposed permit also contains requirements for emergency
engines, in the event such engines are present at the new or proposed
sawmill facility. Each emergency engine must be equipped with a non-
resettable hour meter and, if using fuel oil, then it must use diesel
or biodiesel containing no more than 15 ppm (0.0015 percent) sulfur by
weight. Newer emergency engines--model year 2006 or later for
compression ignition engines and 2009 or later for spark ignition
engines--must meet certain certification or emission requirements that
are contained in the EPA's emissions standards at 40 CFR part 89, 40
CFR part 90 and 40 CFR part 1048 or Table 1 to 40 CFR part 60, subpart
JJJJ, as applicable. Other, older emergency engines are required to
meet certain routine maintenance requirements, and must follow the
manufacturer's emission-related operation and maintenance instructions
or the owner/operator must develop and implement their own maintenance
plan which must provide to the extent practicable for the maintenance
and operation of the engine in a manner consistent with good air
pollution control practice for minimizing emissions.
The proposed general permit includes monitoring that is sufficient
to ensure compliance with the emission limitations that apply to the
source, including ensuring that the baghouses/fabric filters and
cyclones are operating properly, conducting weekly opacity observations
and fugitive emissions surveys and meeting certain other requirements.
The permit also requires performance testing for emergency engines that
must meet certain emissions standards, but are neither required to be
certified by the manufacturer as meeting those standards, nor are in
fact so certified. This requirement is needed since the EPA
certification program for certain engines is voluntary. The proposed
general permit includes recordkeeping and reporting requirements
sufficient to ensure compliance with the monitoring requirements.

[[Page 41867]]

3. Request for Comment on the Proposed General Air Quality Permit for
New or Modified True Minor Source Sawmill Facilities
We request comment on all aspects of the general permit for sawmill
facilities. We specifically request comment in the following two areas:
(a) Use of Tons Per Year Numbers as Emission Limitations
The EPA is proposing to include annual allowable emission
limitations for the sawmills source category. The proposed general
permit includes both a limitation of 25 million board feet on a 12-
month rolling total and total tpy VOC emissions limitations for the
facility regardless of its location. The tpy limitations become more
stringent in ozone nonattainment areas as the classification increases
from marginal to extreme.\42\ We set the proposed VOC emissions
limitations at levels that we believe are sufficiently below the NSR
major source levels to accommodate any additional VOC emissions from
any boilers or emergency engines also present at the facility beyond
VOC emissions from lumber drying kilns. Sources will need to monitor
their board-foot production and perform emission factor calculations
using the calculator and emissions factors that we are providing to
ensure they are staying within the permitted tpy limitations.
---------------------------------------------------------------------------

\42\ Information on these limitations is available at:
Background Document: General Air Quality Permit for New or Modified
True Minor Source Sawmill Facilities, Docket ID No. EPA-HQ-OAR-2011-
0151, https://www.epa.gov/air/tribal/tribalnsr.html.
---------------------------------------------------------------------------

Aside from the maximum 25 million board-feet limit, we opted to not
propose surrogate throughput limits for VOC emissions for sawmills, as
we did for one other source category, because of the diversity of wood
species (and associated emissions) that a sawmill facility may use. It
would be very difficult to set a board foot throughput limit that could
have broad applicability. Instead, by putting emissions limitations
directly in the permit, it provides the source with flexibility on what
wood species it uses, while ensuring that air quality is protected. We
request comment on the appropriateness of establishing emissions
limitations in the permit (versus a limit on throughput) and whether
the specified limitations are established at the correct levels.
b. Setback Requirement
The proposed general permit requires sawmill facilities to locate
at least 150 feet from the nearest property boundary and 1,000 feet
from the nearest residence. This is consistent with the setback
requirement in the state of Texas' \43\ general permit that includes a
setback requirement for this source category. We believe that this
requirement will minimize the impact of emissions from these sources on
localized air quality. We request comment on whether we should include
this setback requirement in the final permit to provide additional
protection against adverse impacts to local air quality. In addition,
we request comment on whether there are other neighboring types of
buildings from which the setback should apply (e.g., schools, nursing
homes) and whether to require owners/operators of the sawmills subject
to the permit to use physical markers on their property to show
compliance with the setback requirements.
---------------------------------------------------------------------------

\43\ The setback requirement in Texas's general permit is
described at: Background Document: General Air Quality Permit for
New or Modified True Minor Source Sawmill Facilities, Docket ID No.
EPA-HQ-OAR-2011-0151, https://www.epa.gov/air/tribal/tribalnsr.html.
---------------------------------------------------------------------------

VII. Description of the EPA's Proposed Permit by Rule Program in Indian
Country

A. What is a permit by rule?

For purposes of this proposal, a permit by rule is a standard set
of requirements (i.e., emissions limitations, monitoring, recordkeeping
and reporting requirements) that can apply to multiple sources with
similar emissions and other characteristics. This is similar to a
general permit; however, unlike a general permit, we codify the permit
by rule requirements into regulation using a formal rulemaking process.
(While a proposed general permit is subject to notice and comment in
accordance with 40 CFR 49.156 and 40 CFR 49.157, neither the final
general permit itself, nor the requirements therein, are added to the
Code of Federal Regulations.)
For purposes of this proposal, the permit by rule mechanism is a
permit streamlining approach that reduces the time permitting
authorities must devote to reviewing permit applications and issuing
permits for source categories or emissions generating activities that
pose a lower environmental concern. We believe that permits by rule
offer another cost-effective means of issuing permits, and provide a
quicker and simpler alternative mechanism for permitting true minor
sources than the site-specific permit or standard general permit
process.
State and local reviewing authorities use the permit by rule
mechanism to authorize construction of less complex sources, and
sources that emit at specified levels below the major stationary source
thresholds. The EPA has approved several state or local permits by rule
programs into State Implementation Plans (SIPs).\44\ By this proposal,
we would provide similar opportunities for permitting efficiency in
Indian country for a specified source category, while also providing a
level of protection of air quality comparable to that provided by a
general permit.
---------------------------------------------------------------------------

\44\ The EPA has approved the following permits by rule: (1)

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

[[Page 41868]]

B. How would a permit by rule program operate in Indian Country?

As discussed in a prior proposed rule (79 FR 2546, January 14,
2014), once the EPA identifies a source category or emissions
generating activity for which the permit by rule mechanism would offer
permit streamlining benefits, while at the same time protecting air
quality, we will codify a nationally applicable permit by rule for
those similar sources into a new section of the Indian Country Minor
NSR FIP following notice and comment rulemaking procedures. If the
permit by rule will apply only at a regional level, then the EPA
regional reviewing authority will conduct the rulemaking process, and
appropriately limit the applicability of the permit by rule to a
specified geographic area.
As proposed, permits by rule would be used to address source
categories of true minor sources, where the reviewing authority does
not need to conduct an in-depth review to evaluate whether an
individual source qualifies for the permit (i.e., meets the
applicability requirements) and can meet the requirements in the
permit. A source category would be covered by a permit by rule if the
reviewing authority needs to do nothing more than receive confirmation
from an individual source that it meets all appropriate criteria to be
eligible for coverage under the permit by rule and that it intends to
comply with the operational, monitoring and recordkeeping requirements
specified in this rule. (By contrast, under a general permit the source
would need to submit a request for coverage to the reviewing authority
and receive an approval from that authority before starting source
construction.)
In our January 14, 2014 proposed rule, we proposed to amend the
Indian Country Minor NSR rule general permit provisions at 40 CFR
49.156 to set forth the unique elements of the permits by rule
process.\45\ We intend to take final action on the proposed approach as
part of taking final action on the overall January 14, 2014 proposal
and are not re-proposing those elements here. In today's action, in the
alternative, we are proposing a permit by rule for the graphic arts and
printing source category, as described above. If we finalize the
procedure for establishing permits by rule set forth in our January 14,
2014, proposed rule, we will follow the procedure as finalized in
promulgating a final permit by rule for the graphic arts and printing
source category. We will only promulgate a permit by rule for the
graphic arts and printing source category if, after considering any
comments we receive in response to today's proposal, we conclude that
establishing such a permit is appropriate. We seek comment on whether
graphic arts and printing operations is an appropriate source category
for a permit by rule.

C. Requirements of the ESA and NHPA

Similar to general permits, prior to seeking coverage under a
permit by rule, a source must satisfactorily address the permit
requirements related to the ESA and the NHPA. Attached to the request
for coverage,\46\ the EPA provides guidance to assist sources in
complying with these requirements. Section V.F. above describes the
process for complying with the ESA and NHPA in more detail. We seek
comment on the use of this process for the proposed graphic arts and
printing operations permit by rule.
---------------------------------------------------------------------------

\46\ For general permits, we refer to applications submitted to
reviewing authorities for approval as requests for coverage. For
permits by rule, we are proposing to not require that these requests
for coverage be submitted for approval. Instead, sources would be
required to notify the EPA by letter that the request for coverage
has been completed and that the source qualifies for the permit and
will comply with all of its terms and conditions.
---------------------------------------------------------------------------

VIII. Proposed Permits by Rule

As an alternative to a general permit, we are proposing to
establish a permit by rule, for one source category: Graphic arts and
printing operations. We are proposing this source category for a permit
by rule based on our determination that this source category emits
primarily one pollutant (i.e., VOCs), that there is little variation in
the equipment used, and that the compliance requirements are
straightforward and readily verifiable. By contrast, the other five
source categories in today's proposal, to varying degrees, involve more
complex operations, more than one pollutant and more complex compliance
requirements. The source categories are:
Concrete batch plants;
Boilers;
Stationary compression ignition engines;
Stationary spark ignition engines; and
Sawmills.

In Section VI. we describe these source categories and the requirements
in the proposed permits that warrant a general permit proposal for
them, including the multiple emissions units covered.
We are not providing specific regulatory language for the proposed
permit by rule but rather are proposing to codify the requirements of
the proposed general permit for this source category described in
Section VI.D. If, after considering relevant comments received in
response to today's proposed action, we decide to finalize a permit by
rule for the source category, we will codify the requirements as
contained in the proposed general permit for the source category,
including any changes that we deem appropriate based on our review of
public comments on the proposed general permit and other relevant
information. In other words, whether we use the permit by rule or the
standard general permit mechanism, we propose to apply identical
requirements to regulate construction and modification activities of
affected emission units in the graphic arts and printing operations
source category. We believe that the proposed general permit provides
the public with a sufficient understanding of the contents of any final
rule, and, therefore, satisfies our obligations under section 301(a) of
the CAA and the Administrative Procedures Act.
The EPA welcomes comments on all aspects of the proposed general
permit and proposed permit by rule for the graphic arts and printing
operations source category discussed in this notice. In particular, we
request comments on whether the permit by rule terms and conditions for
graphic arts and printing operations should be identical to the general
permit terms and conditions, or whether they should differ.

IX. Implementation Documents and Tools

We are providing several tools and documents to assist sources with
obtaining coverage under the general permits and permit by rule for the
six source categories that are the subject of today's proposal. The
tools are drafted based on our preferred approach of general permits.
If we decide to issue a permit by rule for the graphic arts and
printing operations source category as we are proposing in the
alternative today, then we will need to adjust the wording in the
documents to reflect that tools being made available are for a permit
by rule and not a general permit. The background document for graphic
arts and printing operations supports both our general permit proposal
and permit by rule proposal, in the alternative; therefore, the
document cites both general permits and permits by rule as the permit
types it supports.
The tools consist of the following six types of documents:

[[Page 41869]]

Request for Coverage: This form is for sources seeking to use
general permits and is essentially an application to request coverage
under a general permit. The application asks for contact and location
information, as well as more in-depth operational and source-specific
information. The application will also guide sources through processes
to comply with permit requirements related to the ESA and the NHPA.
The general permit application for graphic arts and printing
operations is more streamlined because sources in the category
represent more straightforward operations, largely involve one air
pollutant (i.e., VOCs) and, therefore, necessitate less intensive
review for approval. The general permit application form for the
category asks for basic solvent usage information and whether the
source has complied or will comply with relevant requirements. By
contrast, the general permit applications for concrete batch plants,
engines, boilers and sawmills request more detailed technical
information about the proposed facility in question because these
facilities are more complex and can involve multiple operations and
pollutants.
For graphic arts and printing operations, this form also serves as
an application for sources seeking coverage under a permit by rule
should the EPA decide to issue one for this category. In such
circumstances, the source would need to complete the shortened
application and keep a record on file. Successfully completing the
application will enable the source to determine if it can certify to
the reviewing authority that it meets the permit's eligibility terms
and conditions, which the source would need to do via a letter in order
to begin its construction or modification.
Questionnaire: This tool is tailored to each source category and
guides sources through a series of questions to determine whether it is
eligible for coverage under a general permit. It is not required to be
completed or submitted. First, the source needs to determine whether it
is a true minor source and, therefore, subject to the requirements of
the minor NSR rule for Indian country. To do this, a source needs to
perform a PTE analysis of all of its new, modified and existing
emissions units (see PTE calculator below). If the source determines
that it is a true minor, the questionnaire asks the source to consider
a series of questions to determine if it qualifies for the specific
general permit or permit by rule. If the source does not qualify for
coverage, then it must seek a site-specific permit under the minor
source program (or a major source permit, if appropriate).
Instructions: The document assists sources with information that
may be useful in completing the request for coverage application.
Permit Terms and Conditions: The permit is a specific document for
each source category that lays out the general and specific terms and
conditions of the permit, including the specific emission limitations
and standards and monitoring, recordkeeping, reporting and notification
requirements.
PTE Calculator: This spreadsheet-based tool helps sources in
specific source categories calculate the PTE of their affected
emissions units, using data the source is expected to have on hand,
such as equipment specifications.
Background Documents: These documents are provided as a reference
and contain important information:
Source category definition and characterization;
State minor source permit programs for that category used
for comparison;
Requirements for general permits and permits by rule for
that category; and
Threshold (emission limitations) development and rationale
for that category.
All of these documents are available online at https://www.epa.gov/air/tribal/tribalnsr.html and Docket ID No. EPA-HQ-OAR-2011-0151.

X. Additional Area Where Comment is Being Sought

A. Should general permits and permits by rule be made available for
sources in the same source category?

In our January 14, 2014 proposed rule, the EPA requested comments
on whether, for certain source categories, the EPA should structure the
permits so that eligible true minor sources can receive coverage under
permits by rule and synthetic minor sources receive coverage under
general permits. In addition, just as we proposed that general permits
are more appropriate for more complex source categories, we requested
comment on whether general permits (and not permits by rule) are more
appropriate for major sources that seek to become ``synthetic'' minor
sources. And, as we proposed that permits by rule are more appropriate
for less complex source categories, we requested comments on whether
permits by rule (and not general permits) are more appropriate for true
minor sources. In this action, we request comment only on whether this
concept should be applied to the graphic arts and printing operations
source category. In the docket, a background document is provided for
this source category, which includes a summary of National Emissions
Inventory data for the category.

XI. Proposed Rule Change to the Indian Country Minor NSR Rule

We are proposing one change to one provision in the existing Indian
country minor NSR rule addressing the time period within which the
reviewing authority must make a determination on whether a request for
coverage under a general permit is complete and to complete its review
of the request for coverage. We are proposing this change only for the
general permit for the graphic arts and printing operations source
category. The Indian County Minor NSR rule currently requires the
reviewing authority to determine whether a request for coverage under a
general permit is complete within 45 days of receiving the request (40
CFR 49.156(e)(4)) and to take final action on the request within 90
days of receiving a complete request (40 CFR 49.156(e)(3)). For the
proposed general permit for the graphic arts and printing operations
source category, we are proposing to shorten the time for determining
whether a request for coverage is complete to 15 days (by that date the
reviewing authority must either determine that the request for coverage
is complete or request any additional information) and to shorten the
time within which the reviewing authority must take final action on the
request to 45 days. We explained our general rationale for taking this
approach for some, but not all, general permits in our January 14,
2014, proposed rule.
We are proposing the shortened time frames for the graphic arts and
printing operations source category only. We also propose to provide
the reviewing authority the option of automatically denying a source's
request for coverage if the source fails to submit any additional
requested information within 15 days of receiving the request from the
reviewing authority to remain consistent with our intent to provide a
streamlined notification and review process. If a reviewing authority
denies a request for coverage because a source fails to submit
requested information by the deadline, the source may re-apply at a
later date to re-initiate the request for coverage.
We believe that a shortened application review process for the
graphic arts and printing operations general permit is justified
because the streamlined nature of the general permit for the graphic
arts and printing operations source category is

[[Page 41870]]

inconsistent with lengthy and potentially open-ended ongoing exchanges
with applicants to obtain necessary information and is not the best use
of limited resources. The applications are lengthier for the other four
source categories in today's proposal and, therefore, a lengthier 90
day review process is appropriate for those categories. In Section IX.,
we explain our reasoning for why the application is shorter for graphic
arts and printing operations and longer for the other four categories.
Allowing this streamlining (combined with a shorter application for
this same category) will allow for reduced processing time for a
general permit coverage request for this category and a reduction in
information required to be included in requests for coverage.

XII. Statutory and Executive Order Reviews

A. Executive Order 12866: Regulatory Planning and Review and Executive
Order 13563: Improving Regulation and Regulatory Review

This action is not a ``significant regulatory action'' under the
terms of EO 12866 (58 FR 51735, October 4, 1993) and is, therefore, not
subject to review under EOs 12866 and 13563 (76 FR 3821, January 21,
2011).

B. Paperwork Reduction Act

This action does not impose an information collection burden under
the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq.
Burden is defined at 5 CFR 1320.3(b). This action merely proposes to
establish general permits and/or permits by rule to satisfy the
requirements of the Indian Country Minor NSR rule. Any burden
associated with information required to be collected pursuant to the
proposed general permits and/or permit by rule has already been
accounted for in the approved information collection request for the
Indian Country Minor NSR rule. Further, any use of the general permits
and/or permit by rule is strictly voluntary. Therefore, this action
does not impose an information collection burden.

C. Regulatory Flexibility Act

The Regulatory Flexibility Act generally requires an agency to
prepare a regulatory flexibility analysis of any rule subject to notice
and comment rulemaking requirements under the Administrative Procedure
Act or any other statute unless the agency certifies that the rule will
not have a significant economic impact on a substantial number of small
entities. Small entities include small businesses, small organizations,
and small governmental jurisdictions.
For purposes of assessing the impacts of today's rule on small
entities, small entity is defined as: (1) A small business as defined
by the Small Business Administration's regulations at 13 CFR 121.201;
(2) a small governmental jurisdiction that is a government of a city,
county, town, school district or special district with a population of
less than 50,000; and (3) a small organization that is any not-for-
profit enterprise which is independently owned and operated and is not
dominant in its field.
After considering the economic impacts of today's proposed rule on
small entities, I certify that this action will not have a significant
economic impact on a substantial number of small entities. The EPA
analyzed the impact of streamlined permitting on small entities in the
Review of New Sources and Modifications in Indian Country (76 FR 38748,
July 1, 2011). Today's action will not impose any requirements on small
entities, as it merely implements a particular aspect of the Review of
New Sources and Modifications in Indian Country.

D. Unfunded Mandates Reform Act

This action contains no federal mandates under the provisions of
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), 2 U.S.C.
1531- 1538 for state, local, or tribal governments or the private
sector. This action imposes no enforceable duty on any state, local or
tribal government or the private sector. Therefore, this action is not
subject to the requirements of sections 202 and 205 of the UMRA. This
action is also not subject to the requirements of section 203 of UMRA
because it contains no regulatory requirements that might significantly
or uniquely affect small governments. This rule has no requirements
applicable to small governments and, as such, does not impose
obligations upon them.

E. Executive Order 13132: Federalism

This action does not have federalism implications. It will not have
substantial direct effects on the states, on the relationship between
the national government and the states, or on the distribution of power
and responsibilities among the various levels of government, as
specified in EO 13132. This action merely proposes to provide sources
in Indian country with streamlined permitting opportunities that are
generally available in states outside of Indian country. It does not
impose any new obligations or enforceable duties on any state, local or
tribal government or the private sector. Thus, EO 13132 does not apply
to this rule.
In the spirit of EO 13132, and consistent with the EPA policy to
promote communications between the EPA and state and local governments,
the EPA specifically solicits comment on this proposed action from
state and local officials.

F. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments

Pursuant to the EO 13175 (65 FR 67249, November 9, 2000), the EPA
may not issue a regulation that has tribal implications, that imposes
substantial direct compliance costs, and that is not required by
statute, unless the federal government provides the funds necessary to
pay the direct compliance costs incurred by tribal governments, or the
EPA consults with tribal officials early in the process of developing
the proposed regulation and develops a tribal summary impact statement.
The EPA has concluded that this action will not impose duties or
responsibilities on tribes, although it will have tribal implications.
The EPA has conducted outreach via on-going monthly meetings with
tribal environmental professionals in the development of this proposed
action. This proposal reflects priorities for developing permits,
comments on the general permits and suggestions for developing permits
by rules developed as a result of that outreach. The EPA will offer
consultation to elected tribal officials immediately after proposal to
provide an opportunity for meaningful and timely input into the
development of this regulation.
The EPA specifically solicits additional comment on this proposed
action from tribal officials.

G. Executive Order 13045: Protection of Children From Environmental
Health Risks and Safety Risks

The EPA interprets EO 13045 (62 FR 19885, April 23, 1997) as
applying only to those regulatory actions that concern health or safety
risks, such that the analysis required under section 5-501 of the EO
has the potential to influence the regulation. This action is not
subject to EO 13045 because it does not establish an environmental
standard intended to mitigate health or safety risks.

H. Executive Order 13211: Actions That Significantly Affect Energy
Supply, Distribution, or Use

This action is not subject to EO 13211 (66 FR 28355 (May 22, 2001))
because

[[Page 41871]]

it is not a significant regulatory action under EO 12866.

I. National Technology Transfer and Advancement Act

Section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (``NTTAA''), Public Law 104-113, 12(d) (15 U.S.C. 272 note)
directs the EPA to use voluntary consensus standards in its regulatory
activities unless to do so would be inconsistent with applicable law or
otherwise impractical. Voluntary consensus standards are technical
standards (e.g., materials specifications, test methods, sampling
procedures, and business practices) that are developed or adopted by
voluntary consensus standards bodies. The NTTAA directs the EPA to
provide Congress, through the Office of Management and Budget,
explanations when the agency decides not to use available and
applicable voluntary consensus standards.
The proposed rulemaking involves technical standards. In the
proposed permits the EPA proposes the use of EPA Methods 5, 7, 9, 10,
18, 22 and 25A of 40 CFR part 60, Appendix A.\47\ Three voluntary
consensus standards were identified as applicable for purposes of this
proposal:
---------------------------------------------------------------------------

\47\ Information on any available voluntary consensus standards
that can used as alternatives to the emissions measurement standards
in the General Air Quality Permit for New or Modified True Minor
Source Spark Ignition Engines can be found in: ``Voluntary Consensus
Standard Results for General Permits and Permits by Rule for the
Indian Country Minor New Source Review Program; 40 CFR part 49,
subparts 156(c) and 162,'' from Robin Segall, Acting Group Leader,
Measurement Technology Group, to Laura McKelvey, Community and
Tribal Programs Group, February 7, 2014, Docket ID No. EPA-HQ-OAR-
2011-0151, https://www.epa.gov/air/tribal/tribalnsr.html.

1. ANSI/ASME PTC 19.10-1981 part 10 ``Flue and Exhaust Gas Analyses''
(alternative to EPA Method 7);
2. ASTM D7520-09 ``Standard Test Method for Determining Opacity of a
Plume in the Outdoor Ambient Atmosphere'' (alternative to EPA Method
9); and
3. ASTM D6420-99 (2010) ``Test method for Determination of Gaseous
Organic Compounds by Direct Interface Gas Chromatography/Mass
Spectrometry'' (alternative to EPA Method 18).

The EPA welcomes comments on this aspect of the proposed rulemaking
and, specifically, invites the public to identify potentially-
applicable voluntary consensus standards and to explain why such
standards should be used in this regulation.

J. Executive Order 12898: Federal Actions To Address Environmental
Justice in Minority Populations and Low-Income Populations

E.O. 12898 (59 FR 7629 (Feb. 16, 1994)) establishes federal
executive policy on environmental justice. Its main provision directs
federal agencies, to the greatest extent practicable and permitted by
law, to make environmental justice part of their mission by identifying
and addressing, as appropriate, disproportionately high and adverse
human health or environmental effects of its programs, policies, and
activities on minorities and low-income populations in the United
States.
The EPA has determined that this proposed rule will not have
disproportionately high and adverse human health or environmental
effects on minority or low-income populations because it does not
affect the level of protection provided to human health or the
environment. This proposed rule merely implements certain aspects of
the Review of New Sources and Modifications in Indian Country. As such,
this proposed action will not have a disproportionately high and
adverse human health or environmental effects on minorities and low-
income populations in the United States.
Our primary goal in developing the general permits and permits by
rule is to ensure that air resources in Indian country will be
protected in the manner intended by the CAA. In particular, this rule
will help minimize air quality impacts from new or modified true minor
sources in Indian country. In addition, we seek to establish a flexible
preconstruction permitting program for minor sources in Indian country
that is comparable to similar programs in neighboring states to create
a more level regulatory playing field for owners and operators within
and outside of Indian country. This rule will reduce an existing
disparity by filling the regulatory gap.
