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

요약

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