## Abstract

EPA is approving a revision to the state implementation plan (SIP) of the Commonwealth of Kentucky to revise the motor vehicle emission budgets (MVEBs) for the Northern Kentucky 1-hour ozone maintenance area for the year 2010. The Northern Kentucky maintenance area, a subset of the Cincinnati-Hamilton maintenance area, includes the three Kentucky counties of Boone, Campbell and Kenton. The Commonwealth's submittal also clearly identifies that the Ohio portion and the Kentucky portion of the Cincinnati-Hamilton maintenance area will have subarea budgets for the purposes of implementing transportation conformity.
