## Abstract

EPA is making determinations that the Greene County and Jackson County ozone nonattainment areas have attained the 8-hour ozone National Ambient Air Quality Standard (NAAQS). These determinations are based on three years of complete, quality-assured ambient air quality monitoring data for the 2002-2004 seasons that demonstrate that the 8- hour ozone NAAQS has been attained in the areas. EPA is approving requests from the State of Indiana to redesignate the Greene County and Jackson County areas to attainment of the 8-hour ozone NAAQS. These requests were submitted by the Indiana Department of Environmental Management (IDEM) on July 15, 2005 and supplemented on September 6, 2005, September 7, 2005, October 6, 2005, and October 20, 2005. In approving these requests, EPA is also approving the State's plans for maintaining the 8-hour ozone NAAQS through 2015 in these areas as a revision to the Indiana State Implementation Plan (SIP). EPA is also finding adequate and approving the State's 2015 Motor Vehicle Emission Budgets (MVEBs) for these areas.
