## Abstract

Today's action consists of two distinct but related final rulemakings briefly characterized here and further discussed in the SUPPLEMENTARY INFORMATION section of this rule. First, EPA is approving 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 for 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.
