Approval and Promulgation of Air Quality Implementation Plans; Pennsylvania; Conversion of the Conditional Approval of the 15 Percent Plan and 1990 VOC Emission Inventory for the Pittsburgh-Beaver Valley Ozone Nonattainment Area to a Full Approval

EPA is taking direct final action to convert its conditional approval of a State Implementation Plan (SIP) revision submitted by the Commonwealth of Pennsylvania to a full approval. This revision satisfies the 15 percent reasonable further progress plan (15% plan) requirements of the Clean Air Act (the Act) for the Metropolitan Pittsburgh-Beaver Valley ozone nonattainment area (the Pittsburgh area). EPA is converting its prior conditional approval of the Pittsburgh 15% plan to full approval because the Commonwealth submitted revisions to the SIP that satisfy the conditions listed in EPA's conditional approval. EPA is also taking direct final action to convert its prior conditional approval of the 1990 volatile organic compound (VOC) base year emissions inventory for the Pittsburgh area to a full approval. The intended effect of this action is to convert the conditional approval of the Commonwealth's 15% plan and its associated 1990 VOC base year inventory for the Pittsburgh area to a full approval. This action is being taken by EPA in accordance with the requirements of the Clean Air Act.
