Approval and Promulgation of Air Quality Implementation Plans; Pennsylvania; Reasonably Available Control Technology Determinations for Case-by-Case Sources Under the 1997 and/or 2008 8-Hour Ozone National Ambient Air Quality Standards
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 six 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 RACT determinations (also referred to as case-by-case or CbC) for sources at six 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/or 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.
