The Environmental Protection Agency (EPA) is determining that the Cincinnati, Ohio-Kentucky-Indiana area is attaining the 2008 ozone National Ambient Air Quality Standard (NAAQS or standard) and approving a request from the Indiana Department of Environmental Management (IDEM) to redesignate the Indiana portion of the Cincinnati area to attainment for the 2008 ozone NAAQS because the request meets the statutory requirements for redesignation under the Clean Air Act (CAA). The Cincinnati area includes Lawrenceburg Township in Dearborn County, Indiana; Butler, Clermont, Clinton, Hamilton, and Warren Counties in Ohio; and, Boone, Campbell, and Kenton Counties in Kentucky. IDEM submitted this request on February 23, 2016, and supplemented that submittal with a revised emissions inventory on May 4, 2016. EPA is also approving, as a revision to the Indiana State Implementation Plan (SIP), the state's plan for maintaining the 2008 ozone standard through 2030 in the Cincinnati area. Additionally, EPA finds adequate and is approving the states' 2020 and 2030 volatile organic compound (VOC) and oxides of nitrogen (NOX) Motor Vehicle Emission Budgets (MVEBs) for the Indiana and Ohio portion of the Cincinnati area. Finally, EPA is approving the 2011 base year emissions inventory submitted by IDEM as meeting the base year emissions inventory requirement of the CAA for the Indiana portion of the Cincinnati area.
