Air Plan Approval; West Virginia; 1997 8-Hour Ozone Standard Second Maintenance Plan for the West Virginia Portion of the Steubenville-Weirton, OH-WV Area Comprising Brooke and Hancock Counties, 38820-38825 [2020-13454]

Download as PDF 38820 Federal Register / Vol. 85, No. 125 / Monday, June 29, 2020 / Proposed Rules from the Regional Transportation Plan (RTP) and the Transportation Improvement Program (TIP) are consistent with the motor vehicle emissions budget (MVEB) contained in the control strategy SIP revision or maintenance plan (40 CFR 93.101, 93.118, and 93.124). An MVEB is defined as ‘‘that portion of the total allowable emissions defined in the submitted or approved control strategy implementation plan revision or maintenance plan for a certain date for the purpose of meeting reasonable further progress milestones or demonstrating attainment or maintenance of the NAAQS, for any criteria pollutant or its precursors, allocated to highway and transit vehicle use and emissions (40 CFR 93.101).’’ Under the conformity rule, LMP areas may demonstrate conformity without a regional emission analysis (40 CFR 93.109(e)). However, because LMP areas are still maintenance areas, certain aspects of transportation conformity determinations still will be required for transportation plans, programs and projects. Specifically, for such determinations, RTPs, TIPs and transportation projects still will have to demonstrate that they are fiscally constrained (40 CFR 93.108), meet the criteria for consultation (40 CFR 93.105 and 40 CFR 93.112) and Transportation Control Measure implementation in the conformity rule provisions (40 CFR 93.113). Additionally, conformity determinations for RTPs and TIPs must be determined no less frequently than every four years, and conformity of plan and TIP amendments and transportation projects is demonstrated in accordance with the timing requirements specified in 40 CFR 93.104. In addition, for projects to be approved they must come from a currently conforming RTP and TIP (40 CFR 93.114 and 93.115). The Charleston Area remains under the obligation to meet the applicable conformity requirements for the 1997 8hour ozone NAAQS. jbell on DSKJLSW7X2PROD with PROPOSALS III. Proposed Action EPA’s review of WVDEP’s December 10, 2019 submittal indicates it meets CAA section 175A and all applicable CAA requirements. EPA is proposing to approve the LMP for the 1997 8-hour ozone NAAQS for the Charleston Area (comprising Kanawha and Putnam Counties), as a revision to the West Virginia SIP. EPA is soliciting public comments on the issues discussed in this document. These comments will be considered before taking final action. VerDate Sep<11>2014 16:45 Jun 26, 2020 Jkt 250001 IV. Statutory and Executive Order Reviews Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the CAA and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, EPA’s role is to approve state choices, provided that they meet the criteria of the CAA. Accordingly, this action merely approves state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this proposed action: • Is not a ‘‘significant regulatory action’’ subject to review by the Office of Management and Budget under Executive Orders 12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011); • Is not an Executive Order 13771 (82 FR 9339, February 2, 2017) regulatory action because SIP approvals are exempted under Executive Order 12866. • Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.); • Is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.); • Does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104–4); • Does not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999); • Is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997); • Is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001); • Is not subject to requirements of Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the CAA; and • Does not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994).

SUPPLEMENTARY INFORMATION: On December 10, 2019, WVDEP submitted a revision to the West Virginia SIP to incorporate a plan for maintaining the 1997 ozone NAAQS through June 13, 2027, in accordance with CAA section 175A.1 jbell on DSKJLSW7X2PROD with PROPOSALS I. Background In 1979, under section 109 of the CAA, EPA established primary and secondary NAAQS for ozone at 0.12 parts per million (ppm), averaged over a 1-hour period. 44 FR 8202 (February 8, 1979). On July 18, 1997 (62 FR 38856),2 EPA revised the primary and secondary NAAQS for ozone to set the acceptable level of ozone in the ambient air at 0.08 ppm, averaged over an 8-hour 1 In its December 10, 2019 submittal, the State consistently refers to the Weirton Area, rather than referring to the West Virginia portion of the Steubenville-Weirton, OH-WV area. While the state’s terminology is technically incorrect, it is clear that what the State refers to as the Weirton Area is identical to the West Virginia portion of the Steubenville-Weirton, OH-WV area designated by EPA pursuant to the 1997 8-Hour ozone NAAQS. See 40 CFR 81.349. 2 In March 2008, EPA completed another review of the primary and secondary ozone standards and tightened them further by lowering the level for both to 0.075 ppm. 73 FR 16436 (March 27, 2008). Additionally, in October 2015, EPA completed a review of the primary and secondary ozone standards and tightened them by lowering the level for both to 0.70 ppm. 80 FR 65292 (October 26, 2015). VerDate Sep<11>2014 16:45 Jun 26, 2020 Jkt 250001 period. EPA set the 8-hour ozone NAAQS based on scientific evidence demonstrating that ozone causes adverse health effects at lower concentrations and over longer periods of time than was understood when the pre-existing 1-hour ozone NAAQS was set. Following promulgation of a new or revised NAAQS, EPA is required by the CAA to designate areas throughout the nation as attaining or not attaining the NAAQS. On April 30, 2004 (69 FR 23858), EPA designated SteubenvilleWeirton, Ohio-West Virginia (OH-WV) as nonattainment for the 1997 8-hr ozone NAAQS. The SteubenvilleWeirton, OH-WV nonattainment area consists of Brooke and Hancock Counties, WV and Jefferson County, OH. Once a nonattainment area has three years of complete and certified air quality data that has been determined to attain the NAAQS, and the area has met the other criteria outlined in CAA section 107(d)(3)(E),3 the state can submit a request to EPA to redesignate the area to attainment. Areas that have been redesignated by EPA from nonattainment to attainment are referred to as ‘‘maintenance areas.’’ One of the criteria for redesignation is to have an approved maintenance plan under CAA section 175A. The maintenance plan must demonstrate that the area will continue to maintain the standard for the period extending 10 years after redesignation, and it must contain such additional measures as necessary to ensure maintenance as well contingency measures as necessary to assure that violations of the standard will be promptly corrected. On May 14, 2007 (72 FR 27060, effective June 13, 2007), EPA approved a redesignation request (and maintenance plan) from WVDEP for the Weirton Area. In accordance with section 175A(b), at the end of the eighth year after the effective date of the redesignation, the state must also submit a second maintenance plan to ensure ongoing maintenance of the standard for an additional 10 years. EPA’s final implementation rule for the 2008 ozone NAAQS revoked the 1997 ozone NAAQS and provided that one consequence of revocation was that areas that had been redesignated to attainment (i.e., maintenance areas) for the 1997 NAAQS no longer needed to 3 The requirements of CAA section 107(d)(3)(E) include attainment of the NAAQS, full approval under section 110(k) of the applicable SIP, determination that improvement in air quality is a result of permanent and enforceable reductions in emissions, demonstration that the state has met all applicable section 110 and part D requirements, and a fully approved maintenance plan under CAA section 175A. PO 00000 Frm 00023 Fmt 4702 Sfmt 4702 38821 submit second 10-year maintenance plans under CAA section 175A(b).4 However, in South Coast Air Quality Management District v. EPA 5 (South Coast II), the United States Court of Appeals for the District of Columbia (D.C. Circuit) vacated EPA’s interpretation that, because of the revocation of the 1997 ozone standard, second maintenance plans were not required for ‘‘orphan maintenance areas,’’ (i.e., areas like Brooke and Hancock Counties) that had been redesignated to attainment for the 1997 NAAQS and were designated attainment for the 2008 ozone NAAQS. Thus, states with these ‘‘orphan maintenance areas’’ under the 1997 ozone NAAQS must submit maintenance plans for the second maintenance period. As previously discussed, CAA section 175A sets forth the criteria for adequate maintenance plans. In addition, EPA has published longstanding guidance that provides further insight on the content of an approvable maintenance plan, explaining that a maintenance plan should address five elements: (1) An attainment emissions inventory; (2) a maintenance demonstration; (3) a commitment for continued air quality monitoring; (4) a process for verification of continued attainment; and (5) a contingency plan. The Calcagni memo 6 provides that states may generally demonstrate maintenance by either performing air quality modeling to show the future mix of sources and emission rates will not cause a violation of the NAAQS or by showing that future emissions of a pollutant and its precursors will not exceed the level of emissions during a year when the area was attaining the NAAQS (i.e., attainment year inventory). See Calcagni memo at 9. EPA further clarified in three subsequent guidance memos describing ‘‘limited maintenance plans’’ (LMPs) that the requirements of CAA section 175A could be met by demonstrating that the area’s design value was well below the NAAQS and that the historical stability of the area’s air quality levels showed that the area was unlikely to violate the NAAQS in the future. Specifically, EPA believes that if the most recent air quality design value for the area is at a level that is below 85% of the standard, or in this case below 0.071 ppm, then EPA considers the state to have met the section 175A requirement for a 4 See 80 FR 12315 (March 6, 2015).

Accordingly, on December 10, 2019, WVDEP submitted a second maintenance plan for the Weirton Area, following EPA’s LMP guidance and demonstrating that the area will maintain the 1997 ozone NAAQS through June 13, 2027, i.e., through the end of the 20-year maintenance period. II. Summary of SIP Revision and EPA Analysis WVDEP’s December 10, 2019 SIP submittal outlines a plan for continued maintenance of the 1997 ozone NAAQS which addresses the criteria set forth in the Calcagni memo as follows. A. Attainment Emissions Inventory A state should develop a comprehensive and accurate inventory of actual emissions for an attainment year which identifies the level of emissions in the area which is sufficient to maintain the NAAQS. The inventory should be developed consistent with EPA’s most recent guidance. For ozone, the inventory should be based on a typical summer day’s emission of oxides of nitrogen (NOX) and volatile organic compounds (VOC), the precursors to ozone formation. In the first maintenance plan for the Weirton Area, WVDEP used 2004 for the attainment year inventory, because 2004 was one of the years in the 2002–2004 three-year period when the area first attained the 1997 8-hour ozone NAAQS. The Weirton Area continued to monitor attainment of the 1997 8-hour ozone NAAQS in 2014. Therefore, the emissions inventory from 2014 represents emissions levels conducive to continued attainment (i.e., maintenance) of the NAAQS. Thus, WVDEP is using 2014 as representing attainment level emissions for its second maintenance plan. WVDEP used 2014 summer day emissions from EPA’s 2014 version 7.0 modeling platform as the basis for the 2014 inventory presented in Table 1.

The 2014 emissions inventory was prepared by WVDEP and uploaded into EPA’s Emissions Inventory System (EIS) for inclusion in EPA’s National Emission Inventory (NEI). The inventory addresses four anthropogenic emission source categories: Stationary (point) sources, stationary nonpoint (area) sources, nonroad mobile, and on-road mobile sources. Point sources are stationary sources that have the potential to emit (PTE) more than 100 tons per year (tpy) of VOC, or more than 50 tpy of NOX, and which are required to obtain an operating permit. Data are collected for each source at a facility and reported to WVDEP. 7 Data in Table 1 only includes tons/day. See Tables 3 and 4 of WVDEP’s December 10, 2019 submittal for data in tons/year. VerDate Sep<11>2014 18:44 Jun 26, 2020 Jkt 250001 The fire emissions sector includes emissions from agricultural burning, prescribed fires, wildfires, and other types of fires. The nonpoint emissions sector includes emissions from equipment, operations, and activities that are numerous and in total have significant emissions. Examples include emissions from commercial and consumer products, portable fuel containers, home heating, repair and refinishing operations, and crematories. The non-road emissions sector includes emissions from engines that are not primarily used to propel transportation equipment, such as generators, forklifts, and marine pleasure craft. The on-road emissions sector includes emissions from engines used primarily to propel equipment on highways and other PO 00000 Frm 00024 Fmt 4702 Sfmt 4702 VOC NOX roads, including passenger vehicles, motorcycles, and heavy-duty diesel trucks. The point source sector includes large industrial operations that are relatively few in number but have large emissions, such as kraft mills, electrical generating units, and pharmaceutical factories. On-road mobile emissions are modelled by WVDEP using EPA’s Motor Vehicle Emission Simulator (MOVES). WVDEP generates nonroad mobile source emissions data through the use of EPA’s NONROAD2014a model. EPA reviewed the supporting documentation submitted by WVDEP and proposes to conclude that the plan’s inventory is acceptable for the purposes of a subsequent maintenance plan under CAA section 175A(b). E:\FR\FM\29JNP1.SGM 29JNP1 38823 Federal Register / Vol. 85, No. 125 / Monday, June 29, 2020 / Proposed Rules B. Maintenance Demonstration In order to attain the 1997 ozone NAAQS, the three-year average of the fourth-highest daily average ozone concentrations (design value, DV) at each monitor within an area must not exceed 0.08 ppm. Based on the rounding convention described in 40 CFR part 50, appendix I, the standard is attained if the DV is 0.084 or below. CAA section 175A requires a demonstration that the area will continue to maintain the NAAQS throughout the duration of the requisite maintenance period. Consistent with the prior guidance documents discussed previously in this document, EPA believes that if the most recent DV for the area is well below the NAAQS (e.g. below 85%, or in this case below 0.071 ppm), the section 175A demonstration requirement has been met, provided that Prevention of Significant Deterioration (PSD) requirements, any control measures already in the SIP, and any Federal measures remain in place through the end of the second 10-year maintenance period (absent a showing consistent with section 110(l) that such measures are not necessary to assure maintenance). For the purposes of demonstrating a stable or improving air quality trend, West Virginia used a weighted design value of the most recent five design values. The five most recent design values available cover the 2012–2018 ambient air monitoring data. This includes 3-year design values for 2012– 2014, 2013–2015, 2014–2016, 2015– 2017, and 2016–2018. Data from 2014, 2015, and 2016 was included in three out of five design values. Table 2 of this document shows the most recent five years of ambient ozone air quality 3-year design values. These design values are from EPA’s Air Quality System (AQS). The 7th column is the 5-year weighted design value calculated by West Virginia. This 5-year weighted design value was calculated by averaging all the 4th Max Ozone values from the years 2012–2018. The 8th column is the 5-year design value average calculated by EPA. The 5-year design value average is calculated by averaging the design values for 2012–2014, 2013–2015, 2014– 2016, 2015–2017, and 2016–2018. The 5-year weighted design value calculated by West Virginia is 0.067 ppm, and the 5-year design value average calculated by EPA is 0.066 ppm, for the Weirton Area, both of which are below the 0.071 ppm threshold level and 79% of the NAAQS. Table 2 of this document shows that the most recent five years of ambient ozone air quality 3-year average DVs for the Weirton Area continue to be below 85% of the 1997 ozone NAAQS. It demonstrates that 8-hour ozone air quality levels are significantly below the level of the standard. jbell on DSKJLSW7X2PROD with PROPOSALS TABLE 2—WEIRTON AREA 8-HOUR OZONE DESIGN VALUES IN PART PER MILLION [ppm] Site 2012–2014 2013–2015 2014–2016 2015–2017 2016–2018 5-Year weighted 5-Year design value average (ppm) Projected 2023 Weirton, WV ................... 0.070 0.067 0.067 0.066 0.065 0.067 0.066 0.060 For the 2023 projections shown in Table 2 of this document, EPA used a 2011-based air quality modeling platform, which includes emissions, meteorology, and other inputs for 2011 as the base year and emissions for 2023 as the future analytic year base case. Specifically, the modeling platform included a variety of data that contained information pertaining to the modeling domain and simulation period. These include gridded, hourly emissions estimates and meteorological data, and boundary concentrations. Separate emissions inventories were prepared for the 2011 base year and the 2023 base case. All other inputs (i.e., meteorological fields, initial concentrations, and boundary concentrations) were specified for the 2011 base year model application and remained unchanged for the future-year model simulations. The 2011 modeling platform and projected 2023 emissions were used to drive the 2011 base year and 2023 future case air quality model simulations. The 2023 projected DV for the Weirton Area is 0.060 ppm, well below the level of the 1997 8-hour ozone NAAQS, 0.08 ppm. Therefore, EPA proposes to determine that future violations of the NAAQS in this area are unlikely. VerDate Sep<11>2014 16:45 Jun 26, 2020 Jkt 250001 C. Continued Air Quality Monitoring and Verification of Continued Attainment Once an area has been redesignated to attainment, the state remains obligated to maintain an air quality network in accordance with 40 CFR part 58, in order to verify the area’s attainment status. In the December 10, 2019 submittal, West Virginia committed to maintaining an appropriate air quality monitoring network, in accordance with 40 CFR part 58. West Virginia will continue to conduct ambient ozone air quality monitoring in the area throughout the term of the maintenance plan to verify continued attainment with the 1997 8-hour ozone NAAQS and to protect any applicable PSD increments. WVDEP states that air quality measurements will be performed in accordance with appropriate regulations and guidance documents along with EPA quality assurance requirements, and monitoring procedures will be determined in accordance with 40 CFR part 58. WVDEP commits to submitting qualityassured ozone data to EPA through the AQS and ultimately certified by the WVDEP. EPA has analyzed the commitments in the plan and PO 00000 Frm 00025 Fmt 4702 Sfmt 4702 determined that they meet the requirements. D. Contingency Plan The contingency plan provisions are designed to promptly correct or prevent a violation of the NAAQS that might occur after redesignation of an area to attainment. Section 175A of the CAA requires that a maintenance plan include such contingency measures as EPA deems necessary to assure that the state will promptly correct a violation of the NAAQS that occurs after redesignation. The maintenance plan should identify the contingency measures to be adopted, a schedule and procedure for adoption and implementation of the contingency measures, and a time limit for action by the state. The state should also identify specific indicators to be used to determine when the contingency measures need to be adopted and implemented. The maintenance plan must include a requirement that the state will implement all pollution control measures that were contained in the SIP before redesignation of the area to attainment. See section 175A(d) of the CAA. WVDEP’s December 10, 2019 submittal outlines its adopted permanent and Federally enforceable control measures in order to regulate E:\FR\FM\29JNP1.SGM 29JNP1 jbell on DSKJLSW7X2PROD with PROPOSALS 38824 Federal Register / Vol. 85, No. 125 / Monday, June 29, 2020 / Proposed Rules emission growth. The Weirton Area’s control measures include the permitting regulations and PSD measures, which will remain in effect through the maintenance plan period. Air permits issued will incorporate applicable PSD, New Source Performance Standard, and National Emission Standards for Hazardous Air Pollutant requirements. WVDEP’s December 10, 2019 submittal included the required contingency plan, to be implemented in the event of NAAQS violations in the future. WVDEP has committed to adopting and implementing one or more of the following control measures within three months after verification of a monitored ozone standard violation in the Weirton Area: (1) Extend the applicability of the VOC reasonably available control technology (RACT) rule to include source categories previously excluded (e.g., wastewater treatment facilities); (2) revise permitting requirements establishing more stringent emissions control measures and/or emissions offsets; (3) implement NOx RACT requirements if necessary; (4) develop regulations to establish plant-wide emission caps; (5) implement Stage II Vapor Recovery regulations; (6) establish a program focusing on increasing the public’s understanding of air quality issues and increasing support for actions to improve the air quality; and (7) initiate voluntary local control measures (e.g., bicycle/pedestrian measures, engine idling reduction, partnership with ground freight industry, increase compliance with open burning restrictions, and school bus engine retrofit program). If there is indeed a violation and the DV exceeds the NAAQS, the contingency plan will be ‘‘triggered,’’ based on the following schedule: (1) Quality assurance procedures must confirm the monitored violation within 45 days of occurrence; (2) a draft rule would be developed by the WVDEP for any regulation chosen, (3) WVDEP will adopt the selected control measure(s) as emergency rule(s) which will be implemented within six months after adoption and will file the rule(s) as legislative rule(s) for permanent authorization by the legislature; and (4) for each voluntary measure selected, the WVDEP will initiate program development with local governments within the area by the start of the following ozone season. Furthermore, if the triennial inventories indicate emissions growth in excess of 10% of the 2011 base-year inventory or if a monitored ozone air quality exceedance pattern indicates that an ozone NAAQS violation may be VerDate Sep<11>2014 16:45 Jun 26, 2020 Jkt 250001 imminent, WVDEP will evaluate existing control measures to ascertain if additional regulatory revisions are necessary to maintain the ozone standards. EPA finds that West Virginia’s contingency measures, as well as the commitment to continue implementing any SIP requirements, satisfy the pertinent requirements of section 175A. Importantly, while EPA notes that West Virginia’s contingency measures option six (increasing public understanding) and seven (voluntary local control measures), are not enforceable measures that standing alone are likely to lead to reductions in emissions that could promptly correct a violation of the NAAQS, their inclusion among other measures that meet that criterion, is overall SIP-strengthening, and their inclusion does not alter EPA’s proposal to find the LMP is fully approvable. determinations, RTPs, TIPs and transportation projects still will have to demonstrate that they are fiscally constrained (40 CFR 93.108), meet the criteria for consultation (40 CFR 93.105 and 40 CFR 93.112) and Transportation Control Measure implementation in the conformity rule provisions (40 CFR 93.113). Additionally, conformity determinations for RTPs and TIPs must be determined no less frequently than every four years, and conformity of plan and TIP amendments and transportation projects is demonstrated in accordance with the timing requirements specified in 40 CFR 93.104. In addition, for projects to be approved they must come from a currently conforming RTP and TIP (40 CFR 93.114 and 93.115). The Weirton Area remains under the obligation to meet the applicable conformity requirements for the 1997 8hour ozone NAAQS. E. Transportation Conformity Transportation conformity is required by section 176(c) of the CAA. Conformity to a SIP means that transportation activities will not produce new air quality violations, worsen existing violations, or delay timely attainment of the NAAQS (CAA 176(c)(1)(B)). EPA’s conformity rule at 40 CFR part 93 requires that transportation plans, programs and projects conform to SIPs and establish the criteria and procedures for determining whether or not they conform. The conformity rule generally requires a demonstration that emissions from the Regional Transportation Plan (RTP) and the Transportation Improvement Program (TIP) are consistent with the motor vehicle emissions budget (MVEB) contained in the control strategy SIP revision or maintenance plan (40 CFR 93.101, 93.118, and 93.124). An MVEB is defined as ‘‘that portion of the total allowable emissions defined in the submitted or approved control strategy implementation plan revision or maintenance plan for a certain date for the purpose of meeting reasonable further progress milestones or demonstrating attainment or maintenance of the NAAQS, for any criteria pollutant or its precursors, allocated to highway and transit vehicle use and emissions (40 CFR 93.101).’’ Under the conformity rule, LMP areas may demonstrate conformity without a regional emission analysis (40 CFR 93.109(e)). However, because LMP areas are still maintenance areas, certain aspects of transportation conformity determinations still will be required for transportation plans, programs and projects. Specifically, for such III. Proposed Action PO 00000 Frm 00026 Fmt 4702 Sfmt 4702 EPA’s review of WVDEP’s December 10, 2019 submittal indicates it meets CAA section 175A and all applicable CAA requirements. EPA is proposing to approve the LMP for the 1997 8-hour ozone NAAQS for the Weirton Area (comprising Brooke and Hancock Counties), as a revision to the West Virginia SIP. EPA is soliciting public comments on the issues discussed in this document. These comments will be considered before taking final action. IV. Statutory and Executive Order Reviews Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the CAA and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, EPA’s role is to approve state choices, provided that they meet the criteria of the CAA. Accordingly, this action merely approves state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this proposed action: • Is not a ‘‘significant regulatory action’’ subject to review by the Office of Management and Budget under Executive Orders 12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011); • Is not an Executive Order 13771 (82 FR 9339, February 2, 2017) regulatory action because SIP approvals are exempted under Executive Order 12866. • Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.); E:\FR\FM\29JNP1.SGM 29JNP1 Federal Register / Vol. 85, No. 125 / Monday, June 29, 2020 / Proposed Rules • Is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.); • Does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104–4); • Does not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999); • Is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997); • Is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001); • Is not subject to requirements of Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the CAA; and • Does not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994). In addition, this proposed rule, pertaining to West Virginia’s second maintenance plan for Brooke and Hancock Counties, does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP is not approved to apply in Indian country located in the state, and EPA notes that it will not impose substantial direct costs on tribal governments or preempt tribal law.

SUPPLEMENTARY INFORMATION: On December 10, 2019, WVDEP submitted a revision to the West Virginia SIP to incorporate a plan for maintaining the 1997 ozone NAAQS through October 16, 2026, in accordance with CAA section 175A.1 I. Background In 1979, under section 109 of the CAA, EPA established primary and secondary NAAQS for ozone at 0.12 parts per million (ppm), averaged over a 1-hour period. 44 FR 8202 (February 8, 1979). On July 18, 1997 (62 FR 38856),2 EPA revised the primary and secondary NAAQS for ozone to set the acceptable level of ozone in the ambient air at 0.08 ppm, averaged over an 8-hour period. EPA set the 8-hour ozone NAAQS based on scientific evidence demonstrating that ozone causes adverse health effects at lower concentrations and over longer periods of time than was understood when the pre-existing 1-hour ozone NAAQS was set. Following promulgation of a new or revised NAAQS, EPA is required by the CAA to designate areas throughout the nation as attaining or not attaining the NAAQS. On April 30, 2004 (69 FR 23858), EPA designated HuntingtonAshland Area, West Virginia-Kentucky (WV-KY) as nonattainment for the 1997 8-hr ozone NAAQS. The HuntingtonAshland Area, WV-KY nonattainment area consists of Cabell and Wayne Counties, WV and Boyd County, KY. 1 In its December 10, 2019 submittal, the State consistently refers to the Huntington Area, rather than referring to the West Virginia portion of the Huntington-Ashland, WV-KY area.

SUPPLEMENTARY INFORMATION: On December 10, 2019, WVDEP submitted a 
revision to the West Virginia SIP to incorporate a plan for maintaining 
the 1997 ozone NAAQS through June 13, 2027, in accordance with CAA 
section 175A.\1\
---------------------------------------------------------------------------

    \1\ In its December 10, 2019 submittal, the State consistently 
refers to the Weirton Area, rather than referring to the West 
Virginia portion of the Steubenville-Weirton, OH-WV area. While the 
state's terminology is technically incorrect, it is clear that what 
the State refers to as the Weirton Area is identical to the West 
Virginia portion of the Steubenville-Weirton, OH-WV area designated 
by EPA pursuant to the 1997 8-Hour ozone NAAQS. See 40 CFR 81.349.
---------------------------------------------------------------------------

I. Background

    In 1979, under section 109 of the CAA, EPA established primary and 
secondary NAAQS for ozone at 0.12 parts per million (ppm), averaged 
over a 1-hour period. 44 FR 8202 (February 8, 1979). On July 18, 1997 
(62 FR 38856),\2\ EPA revised the primary and secondary NAAQS for ozone 
to set the acceptable level of ozone in the ambient air at 0.08 ppm, 
averaged over an 8-hour period. EPA set the 8-hour ozone NAAQS based on 
scientific evidence demonstrating that ozone causes adverse health 
effects at lower concentrations and over longer periods of time than 
was understood when the pre-existing 1-hour ozone NAAQS was set. 
Following promulgation of a new or revised NAAQS, EPA is required by 
the CAA to designate areas throughout the nation as attaining or not 
attaining the NAAQS. On April 30, 2004 (69 FR 23858), EPA designated 
Steubenville-Weirton, Ohio-West Virginia (OH-WV) as nonattainment for 
the 1997 8-hr ozone NAAQS. The Steubenville-Weirton, OH-WV 
nonattainment area consists of Brooke and Hancock Counties, WV and 
Jefferson County, OH.
---------------------------------------------------------------------------

    \2\ In March 2008, EPA completed another review of the primary 
and secondary ozone standards and tightened them further by lowering 
the level for both to 0.075 ppm. 73 FR 16436 (March 27, 2008). 
Additionally, in October 2015, EPA completed a review of the primary 
and secondary ozone standards and tightened them by lowering the 
level for both to 0.70 ppm. 80 FR 65292 (October 26, 2015).
---------------------------------------------------------------------------

    Once a nonattainment area has three years of complete and certified 
air quality data that has been determined to attain the NAAQS, and the 
area has met the other criteria outlined in CAA section 
107(d)(3)(E),\3\ the state can submit a request to EPA to redesignate 
the area to attainment. Areas that have been redesignated by EPA from 
nonattainment to attainment are referred to as ``maintenance areas.'' 
One of the criteria for redesignation is to have an approved 
maintenance plan under CAA section 175A. The maintenance plan must 
demonstrate that the area will continue to maintain the standard for 
the period extending 10 years after redesignation, and it must contain 
such additional measures as necessary to ensure maintenance as well 
contingency measures as necessary to assure that violations of the 
standard will be promptly corrected.
---------------------------------------------------------------------------

    \3\ The requirements of CAA section 107(d)(3)(E) include 
attainment of the NAAQS, full approval under section 110(k) of the 
applicable SIP, determination that improvement in air quality is a 
result of permanent and enforceable reductions in emissions, 
demonstration that the state has met all applicable section 110 and 
part D requirements, and a fully approved maintenance plan under CAA 
section 175A.
---------------------------------------------------------------------------

    On May 14, 2007 (72 FR 27060, effective June 13, 2007), EPA 
approved a redesignation request (and maintenance plan) from WVDEP for 
the Weirton Area. In accordance with section 175A(b), at the end of the 
eighth year after the effective date of the redesignation, the state 
must also submit a second maintenance plan to ensure ongoing 
maintenance of the standard for an additional 10 years.
    EPA's final implementation rule for the 2008 ozone NAAQS revoked 
the 1997 ozone NAAQS and provided that one consequence of revocation 
was that areas that had been redesignated to attainment (i.e., 
maintenance areas) for the 1997 NAAQS no longer needed to submit second 
10-year maintenance plans under CAA section 175A(b).\4\ However, in 
South Coast Air Quality Management District v. EPA \5\ (South Coast 
II), the United States Court of Appeals for the District of Columbia 
(D.C. Circuit) vacated EPA's interpretation that, because of the 
revocation of the 1997 ozone standard, second maintenance plans were 
not required for ``orphan maintenance areas,'' (i.e., areas like Brooke 
and Hancock Counties) that had been redesignated to attainment for the 
1997 NAAQS and were designated attainment for the 2008 ozone NAAQS. 
Thus, states with these ``orphan maintenance areas'' under the 1997 
ozone NAAQS must submit maintenance plans for the second maintenance 
period.
---------------------------------------------------------------------------

    \4\ See 80 FR 12315 (March 6, 2015).
    \5\ 882 F.3d 1138 (D.C. Cir. 2018).
---------------------------------------------------------------------------

    As previously discussed, CAA section 175A sets forth the criteria 
for adequate maintenance plans. In addition, EPA has published 
longstanding guidance that provides further insight on the content of 
an approvable maintenance plan, explaining that a maintenance plan 
should address five elements: (1) An attainment emissions inventory; 
(2) a maintenance demonstration; (3) a commitment for continued air 
quality monitoring; (4) a process for verification of continued 
attainment; and (5) a contingency plan. The Calcagni memo \6\ provides 
that states may generally demonstrate maintenance by either performing 
air quality modeling to show the future mix of sources and emission 
rates will not cause a violation of the NAAQS or by showing that future 
emissions of a pollutant and its precursors will not exceed the level 
of emissions during a year when the area was attaining the NAAQS (i.e., 
attainment year inventory). See Calcagni memo at 9. EPA further 
clarified in three subsequent guidance memos describing ``limited 
maintenance plans'' (LMPs) that the requirements of CAA section 175A 
could be met by demonstrating that the area's design value was well 
below the NAAQS and that the historical stability of the area's air 
quality levels showed that the area was unlikely to violate the NAAQS 
in the future. Specifically, EPA believes that if the most recent air 
quality design value for the area is at a level that is below 85% of 
the standard, or in this case below 0.071 ppm, then EPA considers the 
state to have met the section 175A requirement for a

[[Page 38822]]

demonstration that the area will maintain the NAAQS for the requisite 
period. Accordingly, on December 10, 2019, WVDEP submitted a second 
maintenance plan for the Weirton Area, following EPA's LMP guidance and 
demonstrating that the area will maintain the 1997 ozone NAAQS through 
June 13, 2027, i.e., through the end of the 20-year maintenance period.

II. Summary of SIP Revision and EPA Analysis

    WVDEP's December 10, 2019 SIP submittal outlines a plan for 
continued maintenance of the 1997 ozone NAAQS which addresses the 
criteria set forth in the Calcagni memo as follows.

A. Attainment Emissions Inventory

    A state should develop a comprehensive and accurate inventory of 
actual emissions for an attainment year which identifies the level of 
emissions in the area which is sufficient to maintain the NAAQS. The 
inventory should be developed consistent with EPA's most recent 
guidance. For ozone, the inventory should be based on a typical summer 
day's emission of oxides of nitrogen (NOX) and volatile 
organic compounds (VOC), the precursors to ozone formation. In the 
first maintenance plan for the Weirton Area, WVDEP used 2004 for the 
attainment year inventory, because 2004 was one of the years in the 
2002-2004 three-year period when the area first attained the 1997 8-
hour ozone NAAQS. The Weirton Area continued to monitor attainment of 
the 1997 8-hour ozone NAAQS in 2014. Therefore, the emissions inventory 
from 2014 represents emissions levels conducive to continued attainment 
(i.e., maintenance) of the NAAQS. Thus, WVDEP is using 2014 as 
representing attainment level emissions for its second maintenance 
plan. WVDEP used 2014 summer day emissions from EPA's 2014 version 7.0 
modeling platform as the basis for the 2014 inventory presented in 
Table 1.

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

    The 2014 emissions inventory was prepared by WVDEP and uploaded 
into EPA's Emissions Inventory System (EIS) for inclusion in EPA's 
National Emission Inventory (NEI). The inventory addresses four 
anthropogenic emission source categories: Stationary (point) sources, 
stationary nonpoint (area) sources, nonroad mobile, and on-road mobile 
sources. Point sources are stationary sources that have the potential 
to emit (PTE) more than 100 tons per year (tpy) of VOC, or more than 50 
tpy of NOX, and which are required to obtain an operating 
permit. Data are collected for each source at a facility and reported 
to WVDEP.
---------------------------------------------------------------------------

    \7\ Data in Table 1 only includes tons/day. See Tables 3 and 4 
of WVDEP's December 10, 2019 submittal for data in tons/year.
---------------------------------------------------------------------------

    The fire emissions sector includes emissions from agricultural 
burning, prescribed fires, wildfires, and other types of fires. The 
nonpoint emissions sector includes emissions from equipment, 
operations, and activities that are numerous and in total have 
significant emissions. Examples include emissions from commercial and 
consumer products, portable fuel containers, home heating, repair and 
refinishing operations, and crematories. The non-road emissions sector 
includes emissions from engines that are not primarily used to propel 
transportation equipment, such as generators, forklifts, and marine 
pleasure craft. The on-road emissions sector includes emissions from 
engines used primarily to propel equipment on highways and other roads, 
including passenger vehicles, motorcycles, and heavy-duty diesel 
trucks. The point source sector includes large industrial operations 
that are relatively few in number but have large emissions, such as 
kraft mills, electrical generating units, and pharmaceutical factories. 
On-road mobile emissions are modelled by WVDEP using EPA's Motor 
Vehicle Emission Simulator (MOVES). WVDEP generates nonroad mobile 
source emissions data through the use of EPA's NONROAD2014a model. EPA 
reviewed the supporting documentation submitted by WVDEP and proposes 
to conclude that the plan's inventory is acceptable for the purposes of 
a subsequent maintenance plan under CAA section 175A(b).

B. Maintenance Demonstration

    In order to attain the 1997 ozone NAAQS, the three-year average of 
the fourth-highest daily average ozone concentrations (design value, 
DV) at each monitor within an area must not exceed 0.08 ppm. Based on 
the rounding convention described in 40 CFR part 50, appendix I, the 
standard is attained if the DV is 0.084 or below. CAA section 175A 
requires a demonstration that the area will continue to maintain the 
NAAQS throughout the duration of the requisite maintenance period. 
Consistent with the prior guidance documents discussed previously in 
this document, EPA believes that if the most recent DV for the area is 
well below the NAAQS (e.g. below 85%, or in this case below 0.071 ppm), 
the section 175A demonstration requirement has been met, provided that 
Prevention of Significant Deterioration (PSD) requirements, any control 
measures already in the SIP, and any Federal measures remain in place 
through the end of the second 10-year maintenance period (absent a 
showing consistent with section 110(l) that such measures are not 
necessary to assure maintenance).
    For the purposes of demonstrating a stable or improving air quality 
trend, West Virginia used a weighted design value of the most recent 
five design values. The five most recent design values available cover 
the 2012-2018 ambient air monitoring data. This includes 3-year design 
values for 2012-2014, 2013-2015, 2014-2016, 2015-2017, and 2016-2018. 
Data from 2014, 2015, and 2016 was included in three out of five design 
values. Table 2 of this document shows the most recent five years of 
ambient ozone air quality 3-year design values. These design values are 
from EPA's Air Quality System (AQS). The 7th column is the 5-year 
weighted design value calculated by West Virginia. This 5-year weighted 
design value was calculated by averaging all the 4th Max Ozone values 
from the years 2012-2018. The 8th column is the 5-year design value 
average calculated by EPA. The 5-year design value average is 
calculated by averaging the design values for 2012-2014, 2013-2015, 
2014-2016, 2015-2017, and 2016-2018. The 5-year weighted design value 
calculated by West Virginia is 0.067 ppm, and the 5-year design value 
average calculated by EPA is 0.066 ppm, for the Weirton Area, both of 
which are below the 0.071 ppm threshold level and 79% of the NAAQS. 
Table 2 of this document shows that the most recent five years of 
ambient ozone air quality 3-year average DVs for the Weirton Area 
continue to be below 85% of the 1997 ozone NAAQS. It demonstrates that 
8-hour ozone air quality levels are significantly below the level of 
the standard.

    For the 2023 projections shown in Table 2 of this document, EPA 
used a 2011-based air quality modeling platform, which includes 
emissions, meteorology, and other inputs for 2011 as the base year and 
emissions for 2023 as the future analytic year base case. Specifically, 
the modeling platform included a variety of data that contained 
information pertaining to the modeling domain and simulation period. 
These include gridded, hourly emissions estimates and meteorological 
data, and boundary concentrations. Separate emissions inventories were 
prepared for the 2011 base year and the 2023 base case. All other 
inputs (i.e., meteorological fields, initial concentrations, and 
boundary concentrations) were specified for the 2011 base year model 
application and remained unchanged for the future-year model 
simulations. The 2011 modeling platform and projected 2023 emissions 
were used to drive the 2011 base year and 2023 future case air quality 
model simulations. The 2023 projected DV for the Weirton Area is 0.060 
ppm, well below the level of the 1997 8-hour ozone NAAQS, 0.08 ppm. 
Therefore, EPA proposes to determine that future violations of the 
NAAQS in this area are unlikely.

C. Continued Air Quality Monitoring and Verification of Continued 
Attainment

    Once an area has been redesignated to attainment, the state remains 
obligated to maintain an air quality network in accordance with 40 CFR 
part 58, in order to verify the area's attainment status. In the 
December 10, 2019 submittal, West Virginia committed to maintaining an 
appropriate air quality monitoring network, in accordance with 40 CFR 
part 58. West Virginia will continue to conduct ambient ozone air 
quality monitoring in the area throughout the term of the maintenance 
plan to verify continued attainment with the 1997 8-hour ozone NAAQS 
and to protect any applicable PSD increments. WVDEP states that air 
quality measurements will be performed in accordance with appropriate 
regulations and guidance documents along with EPA quality assurance 
requirements, and monitoring procedures will be determined in 
accordance with 40 CFR part 58. WVDEP commits to submitting quality-
assured ozone data to EPA through the AQS and ultimately certified by 
the WVDEP. EPA has analyzed the commitments in the plan and determined 
that they meet the requirements.

D. Contingency Plan

    The contingency plan provisions are designed to promptly correct or 
prevent a violation of the NAAQS that might occur after redesignation 
of an area to attainment. Section 175A of the CAA requires that a 
maintenance plan include such contingency measures as EPA deems 
necessary to assure that the state will promptly correct a violation of 
the NAAQS that occurs after redesignation. The maintenance plan should 
identify the contingency measures to be adopted, a schedule and 
procedure for adoption and implementation of the contingency measures, 
and a time limit for action by the state. The state should also 
identify specific indicators to be used to determine when the 
contingency measures need to be adopted and implemented. The 
maintenance plan must include a requirement that the state will 
implement all pollution control measures that were contained in the SIP 
before redesignation of the area to attainment. See section 175A(d) of 
the CAA. WVDEP's December 10, 2019 submittal outlines its adopted 
permanent and Federally enforceable control measures in order to 
regulate

[[Page 38824]]

emission growth. The Weirton Area's control measures include the 
permitting regulations and PSD measures, which will remain in effect 
through the maintenance plan period. Air permits issued will 
incorporate applicable PSD, New Source Performance Standard, and 
National Emission Standards for Hazardous Air Pollutant requirements.
    WVDEP's December 10, 2019 submittal included the required 
contingency plan, to be implemented in the event of NAAQS violations in 
the future. WVDEP has committed to adopting and implementing one or 
more of the following control measures within three months after 
verification of a monitored ozone standard violation in the Weirton 
Area: (1) Extend the applicability of the VOC reasonably available 
control technology (RACT) rule to include source categories previously 
excluded (e.g., wastewater treatment facilities); (2) revise permitting 
requirements establishing more stringent emissions control measures 
and/or emissions offsets; (3) implement NOx RACT requirements if 
necessary; (4) develop regulations to establish plant-wide emission 
caps; (5) implement Stage II Vapor Recovery regulations; (6) establish 
a program focusing on increasing the public's understanding of air 
quality issues and increasing support for actions to improve the air 
quality; and (7) initiate voluntary local control measures (e.g., 
bicycle/pedestrian measures, engine idling reduction, partnership with 
ground freight industry, increase compliance with open burning 
restrictions, and school bus engine retrofit program).
    If there is indeed a violation and the DV exceeds the NAAQS, the 
contingency plan will be ``triggered,'' based on the following 
schedule: (1) Quality assurance procedures must confirm the monitored 
violation within 45 days of occurrence; (2) a draft rule would be 
developed by the WVDEP for any regulation chosen, (3) WVDEP will adopt 
the selected control measure(s) as emergency rule(s) which will be 
implemented within six months after adoption and will file the rule(s) 
as legislative rule(s) for permanent authorization by the legislature; 
and (4) for each voluntary measure selected, the WVDEP will initiate 
program development with local governments within the area by the start 
of the following ozone season.
    Furthermore, if the triennial inventories indicate emissions growth 
in excess of 10% of the 2011 base-year inventory or if a monitored 
ozone air quality exceedance pattern indicates that an ozone NAAQS 
violation may be imminent, WVDEP will evaluate existing control 
measures to ascertain if additional regulatory revisions are necessary 
to maintain the ozone standards.
    EPA finds that West Virginia's contingency measures, as well as the 
commitment to continue implementing any SIP requirements, satisfy the 
pertinent requirements of section 175A. Importantly, while EPA notes 
that West Virginia's contingency measures option six (increasing public 
understanding) and seven (voluntary local control measures), are not 
enforceable measures that standing alone are likely to lead to 
reductions in emissions that could promptly correct a violation of the 
NAAQS, their inclusion among other measures that meet that criterion, 
is overall SIP-strengthening, and their inclusion does not alter EPA's 
proposal to find the LMP is fully approvable.

E. Transportation Conformity

    Transportation conformity is required by section 176(c) of the CAA. 
Conformity to a SIP means that transportation activities will not 
produce new air quality violations, worsen existing violations, or 
delay timely attainment of the NAAQS (CAA 176(c)(1)(B)). EPA's 
conformity rule at 40 CFR part 93 requires that transportation plans, 
programs and projects conform to SIPs and establish the criteria and 
procedures for determining whether or not they conform. The conformity 
rule generally requires a demonstration that emissions from the 
Regional Transportation Plan (RTP) and the Transportation Improvement 
Program (TIP) are consistent with the motor vehicle emissions budget 
(MVEB) contained in the control strategy SIP revision or maintenance 
plan (40 CFR 93.101, 93.118, and 93.124). An MVEB is defined as ``that 
portion of the total allowable emissions defined in the submitted or 
approved control strategy implementation plan revision or maintenance 
plan for a certain date for the purpose of meeting reasonable further 
progress milestones or demonstrating attainment or maintenance of the 
NAAQS, for any criteria pollutant or its precursors, allocated to 
highway and transit vehicle use and emissions (40 CFR 93.101).''
    Under the conformity rule, LMP areas may demonstrate conformity 
without a regional emission analysis (40 CFR 93.109(e)). However, 
because LMP areas are still maintenance areas, certain aspects of 
transportation conformity determinations still will be required for 
transportation plans, programs and projects. Specifically, for such 
determinations, RTPs, TIPs and transportation projects still will have 
to demonstrate that they are fiscally constrained (40 CFR 93.108), meet 
the criteria for consultation (40 CFR 93.105 and 40 CFR 93.112) and 
Transportation Control Measure implementation in the conformity rule 
provisions (40 CFR 93.113). Additionally, conformity determinations for 
RTPs and TIPs must be determined no less frequently than every four 
years, and conformity of plan and TIP amendments and transportation 
projects is demonstrated in accordance with the timing requirements 
specified in 40 CFR 93.104. In addition, for projects to be approved 
they must come from a currently conforming RTP and TIP (40 CFR 93.114 
and 93.115). The Weirton Area remains under the obligation to meet the 
applicable conformity requirements for the 1997 8-hour ozone NAAQS.

III. Proposed Action

    EPA's review of WVDEP's December 10, 2019 submittal indicates it 
meets CAA section 175A and all applicable CAA requirements. EPA is 
proposing to approve the LMP for the 1997 8-hour ozone NAAQS for the 
Weirton Area (comprising Brooke and Hancock Counties), as a revision to 
the West Virginia SIP. EPA is soliciting public comments on the issues 
discussed in this document. These comments will be considered before 
taking final action.

IV. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provisions of the CAA and applicable 
Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in 
reviewing SIP submissions, EPA's role is to approve state choices, 
provided that they meet the criteria of the CAA. Accordingly, this 
action merely approves state law as meeting Federal requirements and 
does not impose additional requirements beyond those imposed by state 
law. For that reason, this proposed action:
     Is not a ``significant regulatory action'' subject to 
review by the Office of Management and Budget under Executive Orders 
12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 
2011);
     Is not an Executive Order 13771 (82 FR 9339, February 2, 
2017) regulatory action because SIP approvals are exempted under 
Executive Order 12866.
     Does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);

[[Page 38825]]

     Is certified as not having a significant economic impact 
on a substantial number of small entities under the Regulatory 
Flexibility Act (5 U.S.C. 601 et seq.);
     Does not contain any unfunded mandate or significantly or 
uniquely affect small governments, as described in the Unfunded 
Mandates Reform Act of 1995 (Pub. L. 104-4);
     Does not have Federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
     Is not an economically significant regulatory action based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
     Is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
     Is not subject to requirements of Section 12(d) of the 
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 
note) because application of those requirements would be inconsistent 
with the CAA; and
     Does not provide EPA with the discretionary authority to 
address, as appropriate, disproportionate human health or environmental 
effects, using practicable and legally permissible methods, under 
Executive Order 12898 (59 FR 7629, February 16, 1994).
    In addition, this proposed rule, pertaining to West Virginia's 
second maintenance plan for Brooke and Hancock Counties, does not have 
tribal implications as specified by Executive Order 13175 (65 FR 67249, 
November 9, 2000), because the SIP is not approved to apply in Indian 
country located in the state, and EPA notes that it will not impose 
substantial direct costs on tribal governments or preempt tribal law.
