Approval and Promulgation of Implementation Plans Kentucky: 1-Hour Ozone Maintenance Plan Update for Edmonson Area

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

Today's action consists of two distinct but related final rulemakings briefly characterized here and further discussed in the SUPPLEMENTARY INFORMATION section of the direct final rule for this action. First, EPA is proposing to approve revisions to the Edmonson County portion of the State Implementation Plan (SIP) submitted by the Commonwealth of Kentucky, in draft form, on February 19, 2004, and in final form on August 24, 2004. The August 24, 2004, SIP revision provides the 10-year update to the original 1-hour ozone maintenance plans for three 1-hour ozone maintenance areas, including the Edmonson County Maintenance Area, and also provides revised 2004 motor vehicle emission budgets (MVEBs) and establishes 2015 MVEBs. Through this action, EPA is providing notification of its determination that the Edmonson County portion of the Commonwealth's SIP revision satisfies the requirement of the Clean Air Act (CAA) as amended in 1990 for the 10-year update of the 1-hour ozone maintenance plan for Edmonson County Maintenance Area. Secondly, EPA is providing information on the status of its transportation conformity adequacy determination for the new MVEBs for the year 2015 that are contained in the 10-year update to the 1-hour ozone maintenance plan for the Edmonson County Area. In today's action, EPA is only addressing the portion of the SIP revision for Edmonson County. EPA will take separate action to address the other portions of the SIP revision.

In the final rules section of this Federal Register, the EPA is approving the State's SIP revision as a direct final rule without prior proposal because the Agency views this as a noncontroversial submittal and anticipates no adverse comments. A detailed rationale for the approval is set forth in the direct final rule. If no significant, material, and adverse comments are received in response to this rule, no further activity is contemplated. If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this rule. The 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.
