Due to the receipt of an adverse comment, the EPA is withdrawing the direct final rule approving Ohio's State Implementation Plan for the Oxides of Nitrogen (NO<INF>X</INF>) State Implementation Plan Call. In the direct final rule published on January 16, 2003 (68 FR 2211), EPA stated that if EPA receives adverse comment by February 18, 2003, the NO<INF>X</INF> rule would be withdrawn and not take effect. On February 18, 2003, EPA subsequently received one comment from American Electric Power Service Corporation (AEP). We believe this comment is adverse and therefore, we are withdrawing the direct final rule. EPA will address the comment received from AEP in a subsequent final action based on the proposed action published on January 16, 2003.
