Due to an adverse comment, EPA is withdrawing the direct final rule, published March 25, 2009, approving a revision to the State Implementation Plan (SIP) of the Commonwealth of Kentucky. This revision was provided in accordance with Kentucky's obligations to meet the statutory and regulatory requirements related to the 1997 8-hour ozone standard and section 110(a)(1) of the Clean Air Act for the Huntington-Ashland Area, Lexington Area and Edmonson County. As stated in the direct final rule, if EPA received an adverse comment by April 24, 2009, the rule would be withdrawn and not take effect. EPA subsequently received an adverse comment on April 17, 2009. EPA will address the comment in a subsequent final action based upon the proposed action also published on March 25, 2009. EPA will not institute a second comment period on this action.
