Approval and Promulgation of Air Quality Implementation Plans; West Virginia; Permits for Construction and Major Modification of Major Stationary Sources of Air Pollution for the Prevention of Significant Deterioration

EPA is approving a State Implementation Plan (SIP) revision submitted by the State of West Virginia. The intended effect of this action is to approve the inclusion of nitrogen oxides (NO<INF>x</INF>) as a precursor to ozone in the State of West Virginia for permits for construction and major modification of major stationary sources of air pollution for the prevention of significant deterioration (PSD) areas in West Virginia. This action will also add the Federally equivalent provisions to the rules for the PSD program as they pertain to "reasonable possibility" and delete certain references to pollution control projects (PCPs) and clean units (CUs) to make the West Virginia PSD program consistent with the Federal PSD program. This action is being taken under the Clean Air Act (CAA).
