In accordance with the Clean Air Act (CAA), the Environmental Protection Agency (EPA) is redesignating the Ohio portion of the Steubenville Ohio-West Virginia interstate sulfur dioxide (SO 2 ) nonattainment area (Steubenville nonattainment area) from nonattainment to attainment. EPA is also approving Ohio's maintenance plan. Emissions of SO 2 in the area have been reduced and the air quality in the nonattainment area is currently well below the 2010 SO 2 national ambient air quality standard (NAAQS).
