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

概要

The Environmental Protection Agency (EPA) is taking final action approving a state implementation plan (SIP) revision submitted by the Commonwealth of Pennsylvania. The Pennsylvania Department of Environmental Protection (PADEP) submitted a SIP revision on May 2, 2018 seeking 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 includes a demonstration, pursuant to Clean Air Act (CAA), that amendment of the approved SIP will not interfere with the area's ability to attain or maintain any NAAQS. EPA is approving this revision to remove the PADEP requirement for use of 7.8 psi RVP gasoline in summer months from the Pennsylvania SIP, in accordance with the requirements of the Clean Air Act (CAA).
