Designation of Areas for Air Quality Planning Purposes; Ohio; Redesignation of the Ohio Portion of the Steubenville Sulfur Dioxide Nonattainment Area

摘要

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).
