Approval and Promulgation of Air Quality Implementation Plans; District of Columbia, Maryland, and Virginia; 2002 Base Year Emission Inventory, Reasonable Further Progress Plan, Contingency Measures, Reasonably Available Control Measures, and Transportation Conformity Budgets for the Washington, DC Area 1997 8-Hour Moderate Ozone Nonattainment Area

EPA is proposing to approve State Implementation Plan (SIP) revisions submitted by the District of Columbia, the State of Maryland, and the Commonwealth of Virginia (the States). These revisions pertain to the 2002 base year emissions inventory, the reasonable further progress (RFP) plan, RFP contingency measure, and reasonably available control measure (RACM) requirements of the Clean Air Act (CAA) for the Washington, DC area moderate 1997 8-hour ozone nonattainment area (Washington Area). EPA is also proposing to approve the transportation conformity motor vehicle emissions budgets (MVEBs) associated with this revision. EPA is proposing to approve the SIP revisions because they satisfy the emission inventory, RFP, RACM, RFP contingency measures, and transportation conformity requirements for areas classified as moderate nonattainment for the 1997 8-hour ozone national ambient air quality standard (NAAQS) and demonstrate further progress in reducing ozone precursors. This action is being taken under the CAA.
