Determination of Attainment, Approval and Promulgation of Implementation Plans and Designation of Areas for Air Quality Planning Purposes; Indiana; Redesignation of Allen County 8-hour Ozone Nonattainment Area to Attainment for Ozone; Withdrawal of Direct Final Rule

Due to the receipt of an adverse comment, the EPA is withdrawing the August 30, 2006 (71 FR 51489), direct final rule approving the State of Indiana's May 30, 2006, request to redesignate the 8-hour ozone National Ambient Air Quality Standard (NAAQS) nonattainment area of Allen County, Indiana, to attainment for the 8- hour ozone NAAQS; and for EPA approval of an Indiana State Implementation Plan (SIP) revision containing a 14-year maintenance plan for Allen County. In the direct final rule, EPA stated that if adverse comments were submitted by September 29, 2006, the rule would be withdrawn and not take effect. On September 4, 2006, EPA received a comment. EPA believes this comment is adverse and, therefore, EPA is withdrawing the direct final rule. EPA will address the comment in a subsequent final action based upon the proposed action also published on August 30, 2006 (71 FR 51546). EPA will not institute a second comment period on this action.
