Approval and Promulgation of Air Quality Implementation Plans; Pennsylvania; Volatile Organic Compound Reasonably Available Control Technology for 1997 Ozone Standard

The Environmental Protection Agency (EPA) is taking direct final action to approve revisions to the Commonwealth of Pennsylvania state implementation plan (SIP). This SIP revision pertains to the requirements for reasonably available control technology (RACT) controls for certain sources of volatile organic compounds (VOCs) under the 1997 ozone national ambient air quality standard (NAAQS). This SIP revision includes Pennsylvania's certification that previously adopted RACT controls in Pennsylvania's SIP that were approved by EPA under the 1-hour ozone NAAQS are based on the currently available technically and economically feasible controls, and that they continue to represent RACT for the 1997 ozone NAAQS and a negative declaration that certain categories of sources do not exist in Pennsylvania. This SIP revision does not address Pennsylvania's May 2016 VOC and nitrogen oxides (NOX) RACT rule, ``Additional RACT Requirements for Major Sources of NOX and VOCs,'' also known as RACT II. EPA will take separate action on RACT II. EPA is approving these revisions addressing VOC RACT for the 1997 ozone NAAQS in accordance with the requirements of the Clean Air Act (CAA).
