Abstract
On November 24, 1995, the Governor of Utah submitted a request to redesignate the Salt Lake City (SLC) ``not classified'' carbon monoxide (CO) nonattainment area to attainment for the CO National Ambient Air Quality Standard (NAAQS). The Governor also submitted a CO maintenance plan and revisions to Utah Administrative Code Rule (UACR) R307-1-3.3 to ensure that rules applicable to the SLC CO nonattainment area remain in effect after SLC is redesignated to attainment. On December 9, 1996, the Governor submitted a revised SLC CO maintenance plan that incorporated revised contingency measures, updated air quality monitoring data, and other minor revisions to the maintenance plan. In this action, EPA is approving the SLC redesignation request, the revised maintenance plan, and the changes to UACR R307-1-3.3.
