## Abstract

The Environmental Protection Agency (EPA) is approving, under the Clean Air Act (CAA), a State Implementation Plan (SIP) revision submitted by the Ohio Environmental Protection Agency (OEPA) on July 18, 2014, to address emission inventory requirements for the Cleveland- Akron-Lorain, Ohio (OH) and Columbus, OH ozone nonattainment areas and for the Ohio portion of the Cincinnati, Ohio-Kentucky-Indiana ozone nonattainment area under the 2008 ozone National Ambient Air Quality Standard (NAAQS or standard). The CAA requires emission inventories for all ozone nonattainment areas. The emission inventories contained in Ohio's July 18, 2014, submission meet this CAA requirement. EPA is also confirming that the state of Ohio has acceptable stationary source annual emission statement regulations, which have been previously approved by EPA.
