Abstract
The Environmental Protection Agency (EPA) is taking direct final action to approve a State Implementation Plan (SIP) revision submitted by the State of Utah. On March 9, 2015, the Governor of Utah submitted a revision to the Utah SIP, adding a new rule regarding trading of motor vehicle emission budgets (MVEB) for Utah County. The rule allows trading from the motor vehicle emissions budget for primary particulate matter of 10 microns or less in diameter (PM<INF>10</INF>) to the motor vehicle emissions budget for nitrogen oxides (NO<INF>X</INF>), which is a PM<INF>10</INF> precursor. The resulting motor vehicle emissions budgets for NO<INF>X</INF> and PM<INF>10</INF> may then be used to demonstrate transportation conformity with the SIP. The EPA is taking this action under section 110 of the Clean Air Act (CAA).
