Approval and Promulgation of Air Quality Implementation Plans; Pennsylvania; VOC and NOX RACT Determinations for Seven Individual Sources in the Philadelphia-Wilmington-Trenton Area

EPA is taking final action to approve revisions to the Commonwealth of Pennsylvania's State Implementation Plan (SIP). The revisions were submitted by the Pennsylvania Department of Environmental Protection (PADEP) to establish and require reasonably available control technology (RACT) for seven major sources of volatile organic compounds (VOC) and/or nitrogen oxides ( NO<INF>X</INF>). These sources are located in the Philadelphia-Wilmington-Trenton ozone nonattainment area (the Philadelphia area). EPA is approving these revisions to the SIP in accordance with the Clean Air Act (CAA or the Act).
