Approval and Promulgation of Implementation Plans; Wisconsin; Withdrawal of Direct Final Rule

Due to an adverse comment, the EPA is withdrawing the direct final rule providing new compliance options for sources subject to Wisconsin rules that limit emissions of nitrogen oxides (NO<INF>X</INF>) from large electricity generating units in the Milwaukee-Racine ozone non-attainment area. In the direct final rule published on April 10, 2003 (68 FR 17551), we stated that if we receive any adverse comments by May 12, 2003, the rule would be withdrawn and not take effect. EPA subsequently received adverse comments. EPA will address the comments received in a subsequent final action based upon the proposed action also published on April 10, 2003 (68 FR 17576). EPA will not institute a second comment period on this action.
