Approval and Promulgation of Air Quality Implementation Plans; Pennsylvania; VOC and NOX RACT Determinations for Four Individual Sources in the Pittsburgh-Beaver Valley 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 four major sources of volatile organic compounds (VOC) and nitrogen oxides (NO<INF>X</INF>). These sources are located in the Pittsburgh-Beaver Valley ozone nonattainment area (the Pittsburgh area). EPA is approving these revisions to establish RACT requirements in the SIP in accordance with the Clean Air Act (CAA).
