Approval and Promulgation of Air Quality Implementation Plans; West Virginia; Prevention of Significant Deterioration

EPA is granting full approval of revisions to the West Virginia State Implementation Plan (SIP), submitted by the State of West Virginia through the West Virginia Department of Environmental Protection (WVDEP) on August 31, 2011, with the exception of the narrow issue of the requirement to include condensable emissions of particulate matter (condensables) in the definition of "regulated NSR pollutant" in the State's Prevention of Significant Deterioration (PSD) program. These revisions pertaining to West Virginia's PSD program incorporate preconstruction permitting regulations for fine particulate matter (PM<INF>2.5</INF>) and Greenhouse Gases (GHGs) into the West Virginia SIP. In light of a comment received on the July 31, 2012 proposed rule, EPA is reviewing West Virginia State Rule 45CSR14 to determine the extent to which its definition of "regulated NSR pollutant" satisfies the corresponding Federal definition, and will address this issue in a separate action. In addition, EPA is granting full approval of the PSD portions of other related infrastructure submissions required by the Clean Air Act (CAA) which are necessary to implement, maintain, and enforce the 1997 PM<INF>2.5</INF> and ozone National Ambient Air Quality Standards (NAAQS), the 2006 PM<INF>2.5</INF> NAAQS, and the 2008 lead and ozone NAAQS, with the exception of the narrow issue of the requirement to include condensables in the definition of "regulated NSR pollutant." EPA will address this issue in a separate action. EPA is granting approval of these revisions in accordance with the requirements of the CAA.
