Approval and Promulgation of Air Quality Implementation Plans; Pennsylvania; NOX RACT Determinations for Armco Inc., Butler Operations Main Plant and Butler Operations Stainless Steel Plant Located in the Pittsburgh-Beaver Valley Area; Withdrawal of Direct Final Rule

Due to receipt of a letter of adverse comment, EPA is withdrawing the direct final rule to approve revisions which establish reasonably available control technology (RACT) requirements for Armco Inc., Butler Operations Main Plant and Butler Operations Stainless Steel Plant, major sources of nitrogen oxides (NO<INF>X</INF>) located in the Pittsburgh-Beaver Valley ozone nonattainment area. In the direct final rule published on August 22, 2001 (66 FR 44053), EPA stated that if it received adverse comment by September 21, 2001, the rule would be withdrawn and not take effect. EPA subsequently received adverse comments from the Citizens for Pennsylvania's Future (PennFuture). EPA will address the comments received in a subsequent final action based upon the proposed action also published on August 22, 2001 (66 FR 44097). EPA will not institute a second comment period on this action.
