Background Section 110(a)(1) of the Clean Air Act (CAA) requires, in part, that states submit to EPA plans to maintain any NAAQS promulgated by EPA. EPA interprets this provision to require that areas that were maintenance areas for the 1-hour ozone NAAQS, but attainment for the 8- hour ozone NAAQS submit a plan to demonstrate the continued maintenance of the 8-hour ozone NAAQS. EPA established June 15, 2007, three years after the effective date of the initial 8-hour ozone designations, as the deadline for submission of plans for these areas. On May 20, 2005, EPA issued guidance that applies, in part, to areas that are designated attainment/unclassifiable for the 8-hour ozone standard and that had an approved 1-hour ozone maintenance plan. The purpose of the guidance, referred to as section 110(a)(1) guidance, is to assist the states in the development of a SIP which addresses the maintenance requirements found in section 110(a)(1) of the CAA. There are five components of the section 110(a)(1) maintenance plan which are: (1) An attainment inventory, which is based on actual typical summer day emissions of volatile organic compounds (VOCs) and oxides of nitrogen (NOX) for a ten-year period from a base year as chosen by the state; (2) a maintenance demonstration which shows how the area will remain in compliance with the 8-hour ozone standard for 10 years after the effective date of designations (June 15, 2004); (3) a commitment to continue to operate air quality monitors; (4) a contingency plan that will ensure that a violation of the 8-hour ozone NAAQS is promptly addressed; and (5) an explanation of how the State will track the progress of the maintenance plan. On November 7, 2007 (72 FR 62809), EPA published a notice of proposed rulemaking (NPR) for the State of West Virginia. The NPR proposed approval of the 8-hour ozone maintenance plan for Greenbrier County, as well as concurrent approval of two amendments to its existing 1-hour ozone maintenance plan, which include (a) removal of the obligation to submit a maintenance plan for the 1-hour NAAQS eight years after approval of the initial 1-hour maintenance plan, and (b) removal of the State's obligation to implement contingency measures upon a violation of the 1-hour NAAQS. The formal SIP revision was submitted by West Virginia on November 29, 2006. II. Summary of SIP Revision The WVDEP 8-hour ozone maintenance plan addresses the components of the section 110(a)(1) 8-hour ozone maintenance plan as outlined in EPA's May 20, 2005 guidance. West Virginia requested approval of their 8-hour ozone maintenance plan for Greenbrier County, as well as concurrent approval of two amendments to its existing 1-hour ozone maintenance plan. Emissions Inventory: An emissions inventory is an itemized list of emission estimates for sources of air pollution in a given area for a specified time period. WVDEP has provided a comprehensive and current emissions inventory for NOX and VOCs. WVDEP has chosen to use 2002 as the base year from which it will project emissions. The maintenance plan also includes an explanation of the methodology used for determining the anthropogenic (area and mobile sources) emissions. There are no Title V point sources located in Greenbrier County, so a 2002 point source inventory was not compiled. The inventory is based on emissions from a typical ozone season day. The term ``typical'' refers to emissions being emitted during a typical weekday during the months where ozone concentrations are typically the highest. Maintenance Demonstration and Tracking Progress: With regard to demonstrating continued maintenance of the 8-hour ozone standard, West Virginia projects that the total emissions from Greenbrier County will decrease during the ten-year maintenance period. WVDEP has projected emissions for 10 years from the effective date of initial designations, or 2014. In 2002, the total anthropogenic emissions in Greenbrier County were 7.7 tons/ozone season day for VOCs and 7.4 tons/ozone season day for NOX. The projected 2014 anthropogenic emissions from Greenbrier County are 7.0 tons/ozone season day for VOCs and 4.9 tons/ozone season day for NOX. As such, the plan demonstrates that, from an emissions projections standpoint, emissions are projected to decrease. It is important to note that the formation of ozone is dependent on a number of variables which cannot be estimated through emissions growth and reduction calculations. A few of these variables include weather and the transport of ozone precursors from outside the maintenance area. In the section 110(a)(1) maintenance plan, WVDEP had indicated that the state will track the progress of the maintenance plan by updating the emissions inventory for Greenbrier County approximately every three years. The emissions inventory update will include point, area, and mobile emissions. Information from these future updates will be compared with the projected growth estimates for the 2002 base inventory data to track maintenance of the standard. Ambient Monitoring: With regard to the ambient air monitoring component of the maintenance plan, West Virginia commits to continue operating air quality monitoring stations in accordance with 40 CFR Part 58 throughout the maintenance period to [[Page 1284]] verify maintenance of the 8-hour ozone standard, and will submit quality-assured ozone data to EPA through the AIRS system. Contingency Measures: EPA interprets section 110(a)(1) of the CAA to require that the state develop a contingency plan that will ensure that any violation of a NAAQS is promptly corrected. The purposes of the contingency measures, as outlined in West Virginia's maintenance plan, is to accordingly select and adopt one or more measures outlined in the maintenance plan so as to assure continued attainment in the event that a violation of the ozone NAAQS is measured. Violation of the 8-hour ozone standard would trigger one or more of the control measures outlined in the plan. Approval of two amendments to West Virginia's existing 1-hour maintenance plan has also been requested by WVDEP. Section 175A(b) requires that maintenance plans be updated. The 1-hour maintenance plan for Greenbrier County extends to 2005, but no update has been developed. West Virginia identifies the most important reason for this being that available resources are being devoted to attainment and maintenance of the 8-hour standard since the 8-hour standard is considered by the State to be more protective than the former 1-hour standard upon which the current maintenance plan is based. As such, West Virginia is amending this existing maintenance plan, which is codified at 40 CFR 52.2520(e), for the Greenbrier County 1-hour maintenance area by removing the State's obligation to submit a maintenance plan for the 1-hour NAAQS eight years after approval of the initial 1-hour maintenance plan, and is requesting approval of these amendments. III. Final Action EPA is approving the SIP revisions submitted by WVDEP pertaining to their section 110(a)(1) 8-hour ozone maintenance plan for Greenbrier County, West Virginia. This plan demonstrates how the State intends to maintain the 8-hour NAAQS for ozone. Additionally, EPA is concurrently approving two amendments to the existing 1-hour ozone maintenance plan: (1) Removal of the obligation to submit a maintenance plan for the 1- hour NAAQS 8 years after approval of the initial 1-hour maintenance plan; and (2) removal of the State's obligation to implement contingency measures upon a violation of the 1-hour NAAQS. IV. Statutory and Executive Order Reviews A. General Requirements Under Executive Order 12866 (58 FR 51735, October 4, 1993), this action is not a ``significant regulatory action'' and therefore is not subject to review by the Office of Management and Budget. For this reason, this action is also not subject to Executive Order 13211, ``Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001). This action merely approves state law as meeting Federal requirements and imposes no additional requirements beyond those imposed by state law. Accordingly, the Administrator certifies that this rule will not have a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.). Because this rule approves pre-existing requirements under state law and does not impose any additional enforceable duty beyond that required by state law, it 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). This rule also does not have tribal implications because it will not have a substantial direct effect on one or more Indian tribes, on the relationship between the Federal Government and Indian tribes, or on the distribution of power and responsibilities between the Federal Government and Indian tribes, as specified by Executive Order 13175 (65 FR 67249, November 9, 2000). This action also does not have Federalism implications because it does 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 Executive Order 13132 (64 FR 43255, August 10, 1999). This action merely approves a state rule implementing a Federal requirement, and does not alter the relationship or the distribution of power and responsibilities established in the CAA. This rule also is not subject to Executive Order 13045 ``Protection of Children from Environmental Health Risks and Safety Risks'' (62 FR 19885, April 23, 1997), because it approves a state rule implementing a Federal standard. In reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of the CAA. In this context, in the absence of a prior existing requirement for the State to use voluntary consensus standards (VCS), EPA has no authority to disapprove a SIP submission for failure to use VCS. It would thus be inconsistent with applicable law for EPA, when it reviews a SIP submission, to use VCS in place of a SIP submission that otherwise satisfies the provisions of the CAA. Thus, the requirements of section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) do not apply. This rule does not impose an information collection burden under the provisions of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.). B. Submission to Congress and the Comptroller General The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. EPA will submit a report containing this rule and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal Register. This rule is not a ``major rule'' as defined by 5 U.S.C. 804(2). C. Petitions for Judicial Review Under section 307(b)(1) of the CAA, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by March 10, 2008. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this rule for the purposes of judicial review nor does it extend the time within which a petition for judicial review may be filed, and shall not postpone the effectiveness of such rule or action. This action approving the section 110(a)(1) 8-hour Ozone Maintenance Plan for Greenbrier County, West Virginia, and concurrent approval of two amendments to the existing 1-hour ozone maintenance plan may not be challenged later in proceedings to enforce its requirements.
