The Ohio portion of this area consists of Pierce Township in Clermont County, Ohio. The plan addresses the second 10-year maintenance period for the 2010 sulfur dioxide (SO<INF>2</INF>) National Ambient Air Quality Standards (NAAQS). EPA is proposing to approve Ohio EPA's submittal for the area because it provides for the continued maintenance of the 2010 SO<INF>2</INF> NAAQS through the end of the second 10-year portion of the maintenance period.
