Abstract
EPA is approving the request by Ohio and Indiana to revise the Cincinnati-Hamilton 1997 8-hour ozone maintenance air quality State Implementation Plans (SIPs) to replace the previously approved motor vehicle emissions budgets (budgets) with budgets developed using EPA's Motor Vehicle Emissions Simulator (MOVES) emissions model. The Ohio and Indiana portions of the Cincinnati-Hamilton area include the Ohio Counties of Butler, Clermont, Clinton, Hamilton and Warren, Ohio, and Lawrenceburg Township in Dearborn County, Indiana. Ohio submitted the SIP revision request to EPA on June 29, 2012. Indiana submitted the SIP revision request for parallel processing in a letter dated October 12, 2012, and followed up with a final submittal on December 11, 2012. Ohio and Indiana have submitted identical budgets which cover the Ohio and Indiana portions of the Cincinnati-Hamilton 1997 ozone maintenance area.
