Approval and Promulgation of Air Quality Implementation Plans; Michigan; Revision to the State Implementation Plan Vehicle Inspection and Maintenance Program

요약

In this action, the EPA is approving a revision to the Michigan State Implementation Plan (SIP) for attainment of the National Ambient Air Quality Standards for ozone. On November 12, 1993 and on July 19, 1994 Michigan submitted a SIP revision request to the EPA to satisfy the requirements of sections 182(b)(4) and 182(c)(3) of the Clean Air Act, as amended in 1990 (Act), and the Federal motor vehicle inspection and maintenance (I/M) rule at 40 CFR part 51, subpart S. This revision establishes and requires the implementation of an I/M program in the Grand Rapids and Muskegon ozone nonattainment areas. On July 15, 1994, the EPA published a notice of proposed rulemaking (NPRM) for the State of Michigan. The NPRM proposed approval of the Michigan I/M SIP provided that the State submitted materials sufficient to address the deficiencies found in the original submittal. No public comments were received on the NPRM and the State submitted materials sufficient to remedy all the deficiencies in the original submittal, therefore, the EPA is publishing this final action.
