Approval and Promulgation of Air Quality Implementation Plans; State of Utah; Vehicle Inspection and Maintenance Program; Utah County

요약

EPA is taking direct final action approving a State Implementation Plan revision submitted by the Governor of Utah on December 7, 2001. This SIP submittal consists of a revision to Utah's rule R307-110-34 and section X, Vehicle Inspection and Maintenance (I/ M) Program, Part D, Utah County. This SIP submittal satisfies one of the conditions of EPA's June 9, 1997 interim approval of Utah County's improved vehicle I/M program SIP. The other condition of EPA's interim approval was submittal of a demonstration that Utah County's decentralized I/M program can obtain the same emission reduction credits as a centralized I/M program. The State submitted such a demonstration on May 20, 1999. These submittals meet the requirements of section 348 of the National Highway System Designation Act, which allows States to claim additional credit for their decentralized I/M programs. In this case, Utah has demonstrated that Utah County's improved vehicle I/M program is entitled to 100% emissions reduction credit.
