          - 40 CFR Parts 52 and 81 
          - [R04-OAR-2005-TN-0007-200527(b); FRL-7973-4] 

# AGENCY:

Environmental Protection Agency (EPA). 

# ACTION:

Proposed rule. 

# SUMMARY:

                        On August 10, 2005, the State of Tennessee, through the Tennessee Department of Environment and Conservation (TDEC), Air Pollution Control Division, submitted a final request: To redesignate the Montgomery County, Tennessee portion of the Clarksville-Hopkinsville 8-hour ozone nonattainment area to attainment for the 8-hour ozone National Ambient Air Quality Standard (NAAQS), and to approve a Tennessee State Implementation Plan (SIP) revision containing a 12-year maintenance plan for Montgomery County, Tennessee. 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 Montgomery County, Tennessee portion of the Clarksville-Hopkinsville 8-hour ozone nonattainment area. Additionally, EPA is approving the 8-hour ozone maintenance plan for Montgomery County, Tennessee. This approval is based on EPA's determination that the                               ( print page 55614)                            State of Tennessee has demonstrated that Montgomery County, Tennessee 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 March 21, 2005, the Commonwealth of Kentucky submitted a redesignation request and maintenance plan for the Christian County, Kentucky 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 year 2016 that are contained in the 12-year 8-hour ozone maintenance plan for Montgomery County, Tennessee. EPA is approving such MVEBs.
