Abstract
The Environmental Protection Agency (EPA) is approving a redesignation request and state implementation plan (SIP) revisions submitted by the State of West Virginia related to the 2010 primary national ambient air quality standard (NAAQS or Standard) for sulfur dioxide (SO<INF>2</INF>) (2010 SO<INF>2</INF> NAAQS). Emissions of SO<INF>2</INF> in the Marshall, West Virginia Area have been permanently reduced, a maintenance plan has been adopted that includes limits that assure continued attainment and monitored ambient SO<INF>2</INF> readings in the nonattainment area are currently well below the 2010 SO<INF>2</INF> NAAQS. The effect of this action changes the designation of the Marshall Area from nonattainment to attainment of the 2010 SO<INF>2</INF> NAAQS. This action is being taken under the Clean Air Act (CAA).
