Approval and Promulgation of Air Quality Implementation Plans; Pennsylvania; Withdrawal of Direct Final Rule

Due to adverse comments, EPA is withdrawing the direct final rule to amend Pennsylvania's ten-year plan to maintain the 1-hour ozone national ambient air quality standard (NAAQS) in the Pittsburgh-Beaver Valley ozone maintenance area (the Pittsburgh area). In the direct final rule published on July 1, 2004 (69 FR 39854), we stated that if we received adverse comment by August 2, 2004, the rule would be withdrawn and not take effect.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 July 1, 2004. EPA will not institute a second comment period on this action.
