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

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.
