Approval and Promulgation of Air Quality Implementation Plans; Delaware; Reasonable Further Progress Plan, 2002 Base Year Inventory, Reasonably Available Control Measures, Contingency Measures, and Transportation Conformity Budgets for the Delaware Portion of the Philadelphia 1997 8-Hour Ozone Moderate Nonattainment Area

EPA is approving a revision to the Delaware State Implementation Plan (SIP) to meet the reasonable further progress (RFP) requirements of the Clean Air Act (CAA) for the Delaware portion of the Philadelphia 1997 8-hour ozone moderate nonattainment area. EPA is also approving the RFP plan's motor vehicle emissions budgets (MVEBs), the 2002 base year emissions inventory, contingency measures, and the reasonably available control measure (RACM) analysis associated with this revision. EPA is approving the SIP revision because it satisfies the requirements for the 1997 8-hour ozone national ambient air quality standard (NAAQS) nonattainment areas classified as moderate and demonstrates further progress in reducing ozone precursors. EPA is approving the SIP revision pursuant the CAA and EPA's regulations.
