Approval and Promulgation of 

Implementation Plans and Designation 

of Areas for Air Quality Planning 

Purposes; Kentucky; Redesignation of 

the Christian County, Kentucky Portion 

of the Clarksville-Hopkinsville 8-Hour 

Ozone Nonattainment Area to 

Attainment for Ozone 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Proposed rule. 

SUMMARY: 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 proposing to approve the 8-hour 

ozone redesignation request for the 

Christian County, Kentucky portion of 

the Clarksville-Hopkinsville 8-hour 

ozone nonattainment area. Additionally, 

EPA is proposing to approve the 8-hour 

ozone maintenance plan for Christian 

County, Kentucky. This proposed 

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 emission 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 proposing to 

approve such MVEBs. In the Final Rules 

section of this Federal Register, EPA is 

taking action to approve the 

redesignation request and maintenance 

plan without prior proposal. A detailed 

rationale for the redesignation and other 

actions is set forth in the direct final 

rule. If no adverse comments are 

received in response to this action, no 

further activity is contemplated. If EPA 

receives adverse comments, the direct 

final rulemaking will be withdrawn and 

public comments received will be 

addressed in a subsequent final rule 

based on this proposed rule. EPA will 

not institute a second comment period 

on this document. Any parties 

interested in commenting on this 

document should do so at this time. 

DATES: Comments must be received on 

or before October 24, 2005.
