Abstract
On March 21, 2005, the Commonwealth of Kentucky, through the Kentucky Division For Air Quality (KDAQ), submitted a request for parallel processing and on May 20, 2005, submitted a final request: To redesignate the Christian County, Kentucky portion of the Clarksville- Hopkinsville 8-hour ozone nonattainment area to attainment for the 8- hour ozone National Ambient Air Quality Standard (NAAQS); and for EPA approval of a Kentucky State Implementation Plan (SIP) revision containing a 12-year maintenance plan for Christian County, Kentucky. The interstate Clarksville-Hopkinsville 8-hour ozone nonattainment area is comprised of two counties (i.e., Christian County, Kentucky and Montgomery County, Tennessee). EPA is approving the 8-hour ozone redesignation request for the Christian County, Kentucky portion of the Clarksville-Hopkinsville 8-hour ozone nonattainment area. Additionally, EPA is approving the 8-hour ozone maintenance plan for Christian County, Kentucky. This approval is based on EPA's determination that the Commonwealth of Kentucky has demonstrated that Christian County, Kentucky has met the criteria for redesignation to attainment specified in the Clean Air Act (CAA), including the determination that the entire Clarksville-Hopkinsville 8-hour ozone nonattainment area has attained the 8-hour ozone standard. On June 29, 2005, the State of Tennessee submitted a redesignation request and maintenance plan for the Montgomery, Tennessee portion of this area for EPA parallel processing. In this action, EPA is also providing information on the status of its transportation conformity adequacy determination for the new motor vehicle emissions budgets (MVEBs) for the years 2004 and 2016 that are contained in the 12-year 8-hour ozone maintenance plan for Christian County, Kentucky. EPA is approving such MVEBs.
