## Abstract

The Environmental Protection Agency (EPA) is approving the request from the State of West Virginia to redesignate to attainment its respective portion of the Steubenville, Ohio-West Virginia multi- state sulfur dioxide (SO<INF>2</INF>) nonattainment area (referred to as the "Steubenville Nonattainment Area" or the "Area") for the 2010 1-hour SO<INF>2</INF> primary national ambient air quality standard (NAAQS) (also referred to as the "2010 SO<INF>2</INF> NAAQS"). EPA is also approving, as a revision to the West Virginia state implementation plan (SIP), West Virginia's maintenance plan for its portion of the Steubenville Nonattainment Area. Emissions of SO<INF>2</INF> in the Area have been reduced, and monitored ambient SO<INF>2</INF> readings in the nonattainment area are currently well below the 2010 SO<INF>2</INF> NAAQS.
