## Abstract

EPA is determining that the City of Weirton PM<INF>10</INF> nonattainment area (the Weirton area) has attained the National Ambient Air Quality Standard (NAAQS) for PM<INF>10</INF>. This determination is based on three years of complete, quality-assured, ambient air quality monitoring data for the years 2000-2002 which demonstrate that the NAAQS for PM<INF>10</INF> has been attained in the area. On the basis of this determination, EPA is also determining that certain attainment demonstration requirements along with other related requirements of the Clean Air Act (CAA), are no applicable to the Weirton area. EPA is also approving the West Virginia Department of Environmental Protection's (WVDEP) request to redesignate the Weirton area to attainment of the NAAQS for PM<INF>10</INF>. In conjunction with its approval of this redesignation request, EPA is also approving WVDEP's 10-year maintenance plan for the Weirton area as a revision to the West Virginia State Implementation Plan (SIP). EPA is taking these actions in accordance with the requirements of the Clean Air Act.
