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

Due to receipt of adverse comment, EPA is withdrawing the direct final rule for the approval of revisions to the Pennsylvania State Implementation Plan (SIP). EPA published the direct final rule on September 16, 1998 (63 FR 49436), approving revisions to supplement Pennsylvania's enhanced motor vehicle emissions inspection and maintenance (I/M) program. As stated in that Federal Register document, if adverse comments were received by October 16, 1998, a timely withdrawal would be published in the Federal Register. EPA subsequently received adverse comments on that direct final rule. EPA will address the comments received in a subsequent final action and issue a final rule based on the parallel proposal also published on September 16, 1998 (63 FR 49517). In a separate document appearing in the Proposed Rules section, EPA is announcing extension of the comment period on this action.
