Abstract
On March 21, 2002, EPA published a notice of proposed rulemaking (NPR) that proposed approval of revisions to Utah's state air quality implementation plan (SIP). The revisions update Utah's vehicle inspection and maintenance (I/M) programs. On August 14, 2001 and on August 15, 2001, the Governor of Utah submitted revisions to the SIP affecting the State's motor vehicle I/M programs. The August 14, 2001, submittal revised Utah's Rule R307-110-33, which incorporates by reference Section X, Vehicle Inspection and Maintenance Program, Part C, Salt Lake County to allow Salt Lake County to take 100% credit for their test and repair vehicle I/M network, rather than the previously required EPA default of a 50% emissions reduction credit. The August 15, 2001, submittal revises Utah's Rule R307-110-31, which incorporates by reference Section X, Vehicle Inspection and Maintenance Program, Part A, General Requirements and Applicability to require mandatory implementation of the inspection of vehicle On-Board Diagnostic (OBD) systems starting January 1, 2002. In this action, EPA is approving the revisions to Utah's Rule R307-110-33 and Rule R307-110-31.
