## Abstract

EPA is approving two State Implementation Plan (SIP) revisions submitted by the State of West Virginia. The first revision amends West Virginia's Prevention of Significant Deterioration (PSD) regulation by amending definitions, establishing the maximum increase in ambient nitrogen dioxide concentrations allowed in an area above the baseline concentration (the increment) and updating the references to federal air quality modeling procedures. The second revision removes increment provisions for total suspended particulates (TSP) and replaces them with increment provisions for particulate matter with an aerodynamic diameter of less than or equal to a nominal 10 micrometers (PM-10). The second revision also updates the references to federal air quality modeling procedures and adds provisions for pollution control projects at electric utilities. The intended effect of this action is to approve revisions to West Virginia's PSD regulation as it meets federal requirements. This action is being taken under section 110 of the Clean Air Act.
