Approval and Promulgation of Air Quality Implementation Plans; Pennsylvania; Reasonably Available Control Technology Determinations for Case-by-Case Sources Under the 1997 and 2008 8-Hour Ozone National Ambient Air Quality Standards

Issuing agencies

Abstract

The Environmental Protection Agency (EPA) is approving multiple state implementation plan (SIP) revisions submitted by the Commonwealth of Pennsylvania. These revisions were submitted by the Pennsylvania Department of Environmental Protection (PADEP) to establish and require reasonably available control technology (RACT) for 23 major volatile organic compound (VOC) and/or nitrogen oxide (NO<INF>X</INF>) emitting facilities pursuant to the Commonwealth of Pennsylvania's conditionally approved RACT regulations. In this rule action, EPA is approving source-specific (also referred to as case-by- case or CbC) RACT determinations or alternative NO<INF>X</INF> emissions limits for sources at 23 major NO<INF>X</INF> and VOC emitting facilities within the Commonwealth submitted by PADEP. These RACT evaluations were submitted to meet RACT requirements for the 1997 and 2008 8-hour ozone national ambient air quality standards (NAAQS). EPA is approving these revisions to the Pennsylvania SIP in accordance with the requirements of the Clean Air Act (CAA) and EPA's implementing regulations.
