transportation buffer to the mobile emissions inventory projections for PM 2.5 and nitrogen oxides (NO X ) in 2017 and 2025. The Tier 2 MVEBs will become effective if it is determined that technical uncertainties primarily due to model changes and to vehicle fleet turnover, which may affect future motor vehicle emissions inventories, lead to motor vehicle emissions estimates above the Tier 1 MVEBs. The determination will be made through the interagency consultation process and fully documented within the first conformity analysis that uses the Tier 2 MVEBs. Receipt of the submittal was announced on EPA’s transportation conformity Web site. No comments were received. The findings letter is available at EPA’s conformity Web site: http:// www.epa.gov/otaq/stateresources/ transconf/adequacy.htm. The adequate direct particulate matter (PM) and NO X MVEBs for Tier 1 and Tier 2 are provided in Table 1 and Table 2.

Transportation conformity is required by section 176(c) of the Clean Air Act (CAA). EPA’s conformity rule requires that transportation plans, transportation improvement programs, and projects conform to SIPs and establishes the criteria and procedures for determining whether or not they do. Conformity to a SIP means that transportation activities will not produce new air quality violations, worsen existing violations, or delay timely attainment of the national ambient air quality standards. The criteria by which we determine whether a SIP’s MVEBs are adequate for conformity purposes are outlined in 40 CFR 93.118(e)(4). EPA described the process for determining the adequacy of submitted SIP budgets in a July 1, 2004 preamble starting at 69 FR 40038 and used the information in these resources in making this adequacy determination. Maryland did not provide emission budgets for sulfur dioxide (SO 2 ), volatile organic compounds (VOCs), or ammonia for the Washington Area’s Maintenance Plan because it concluded that emissions of these precursors from motor vehicles are not significant contributors to the area’s PM 2.5 air quality problem. The transportation conformity rule provision at 40 CFR 93.102(b)(2)(v) indicates that conformity does not apply for these precursors, due to the lack of motor vehicle emissions budgets for these precursors and state’s conclusion that motor vehicle emissions of SO 2 , VOCs, and ammonia do not contribute significantly to the area’s
PM 2.5 nonattainment problem. This provision of the transportation conformity rule predates and was not disturbed by the January 4, 2013 decision in the litigation on the PM 2.5 implementation rule. EPA has preliminarily concluded that the State’s decision to not include budgets for SO 2 , VOCs, and ammonia is consistent with the requirements of the transportation conformity rule. That decision does not affect EPA’s adequacy finding for the submitted direct PM and NO X MVEBs for the Washington Area’s Maintenance Plan.

Please note that an adequacy review is separate from EPA’s completeness review, and should not be used to prejudge EPA’s ultimate approval action for the SIP. Even if EPA finds the budgets for the Washington Area’s Maintenance Plan adequate, the SIP could later be disapproved. The finding and the response to comments are available at EPA’s conformity Web site: http://www.epa.gov/otaq/ stateresources/transconf/adequacy.htm.

**AGENCY :**  Environmental Protection Agency (EPA).

**ACTION :**  Notice of adequacy.

**SUMMARY :**  In this notice, the Environmental Protection Agency (EPA) is notifying the public that EPA has found that the motor vehicle emissions budgets (MVEBs) in the Commonwealth of Virginia portion of the Metropolitan Washington, DC, (DC-MD-VA) 1997 Fine Particulate (PM 2.5 ) National Ambient Air Quality Standard (NAAQS) Nonattainment Area (hereafter, the Washington Area) Maintenance Plan, submitted as a State Implementation Plan (SIP) revision by the Virginia Department of Environmental Quality (VADEQ), are adequate for transportation conformity purposes.

**DATES :**  This finding is effective on May 13, 2014.

**SUPPLEMENTARY INFORMATION :** 

Today’s notice is simply an announcement of a finding that EPA has already made. EPA Region III sent a letter to VADEQ on March 25, 2014, stating that EPA has found that the MVEBs in the Washington Area’s Maintenance Plan for budget years 2017 and 2025, submitted on June 3, 2013 by VADEQ, are adequate for transportation conformity purposes. As a result of EPA’s finding, the Commonwealth of Virginia must use the 2017 and 2025 Tier 1 MVEBs shown in Table 1 from the Washington Area’s Maintenance Plan for future conformity determinations for the 1997 PM 2.5 NAAQS. The Tier 2 MVEBS shown in Table 2 adds a twenty percent (20%) transportation buffer to the mobile emissions inventory projections for PM 2.5 and nitrogen oxides (NO
x ) in 2017 and 2025. The Tier 2 MVEBs will become effective if it is determined that technical uncertainties primarily due to model changes and to vehicle fleet

turnover, which may affect future motor vehicle emissions inventories, lead to motor vehicle emissions estimates above the Tier 1 MVEBs. The determination will be made through the interagency consultation process and fully documented within the first conformity analysis that uses the Tier 2 MVEBs. Receipt of the submittal was announced on EPA’s transportation conformity Web site. No comments were received.
