ENVIRONMENTAL PROTECTION AGENCY
40 CFR Parts 52 and 81
[R04-OAR-2005-KY-0001-200521(b); FRL-7973-1]
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.
ADDRESSES: Comments may be mailed to Stacy DiFrank, Regulatory
Development Section, Air Planning Branch, Air, Pesticides and Toxics
