Approval and Promulgation of Air Quality Implementation Plans; Pennsylvania; Removal of Department of Environmental Protection Gasoline Volatility Requirements for the Pittsburgh-Beaver Valley Area

The Environmental Protection Agency (EPA) is taking direct final action to approve a revision to the Commonwealth of Pennsylvania state implementation plan (SIP) submitted by the Pennsylvania Department of Environmental Protection (PADEP) on May 2, 2018. This revision seeks the removal, from the Pennsylvania SIP, of the requirement limiting summertime gasoline volatility to 7.8 pounds per square inch (psi) Reid Vapor Pressure (RVP) to address nonattainment under the 1-hour ozone national ambient air quality standard (NAAQS) in the Pittsburgh-Beaver Valley ozone nonattainment area (hereafter Pittsburgh-Beaver Valley Area). The submitted SIP revision also includes a section 110(l) demonstration as required by the Clean Air Act (CAA) addressing emission impacts associated with the removal of the program. EPA is approving these revisions to the Pennsylvania SIP in accordance with the requirements of the Clean Air Act (CAA).
