Approval and Promulgation of Air Quality Implementation Plans; Commonwealth of Pennsylvania; Interim Final Determination that Pennsylvania Continues to Correct the Deficiencies of its Enhanced I/M SIP Revision

Riepilogo

Elsewhere in today's Federal Register, EPA has published a direct final rule granting full conditional approval of the Commonwealth of Pennsylvania's enhanced motor vehicle inspection and maintenance (I/M) program, under section 348 of the National Highway System Designation Act of 1995 (NHSDA) and section 110 of the Clean Air Act (CAA). Based on the approval, EPA is making an interim final determination, by this action, that the Commonwealth has continued to correct the deficiency prompting the original disapproval of the Pennsylvania enhanced I/M SIP revision. This action will defer the application of the offset sanction which would have been implemented on August 29, 1998, and defers the future application of the highway sanction. Although this action is effective upon publication, EPA will take comment on this interim final determination as well as EPA's approval of the Commonwealth's submittal. EPA will publish a final action taking into consideration any comments received on EPA's direct final rule and this interim final action.
