Summary

EPA is proposing action on a state implementation plan (SIP) revision submitted by the State of Arizona on behalf of the Maricopa Association of Governments (MAG) to meet Clean Air Act (CAA or “the Act”) requirements for the 2008 ozone national ambient air quality standards (NAAQS or “standards”) in the Phoenix-Mesa (“Phoenix”) ozone nonattainment area. The EPA is proposing to approve the portions of the “MAG 2017 8-Hour Ozone Moderate Area Plan” (“MAG 2017 Ozone Plan” or “Plan”) that address the requirements for emissions inventories, a demonstration of attainment by the applicable attainment date, reasonably available control measures, reasonable further progress (RFP), motor vehicle emission budgets for transportation conformity, vehicle inspection and maintenance programs, new source review rules, and offsets. The EPA is proposing to disapprove the portion of the MAG 2017 Ozone Plan that addresses the requirements for contingency measures for failure to attain or to make RFP. However, based on a separate proposed action finding that the Phoenix nonattainment area attained the 2008 ozone standard by the applicable attainment date, we are also proposing to determine that the requirement for contingency measures will no longer apply to the Phoenix nonattainment area. Finally, we are proposing to approve the portions of a SIP revision, the “2014 Eight-Hour Ozone Plan—Submittal of Marginal Area Requirements for the Maricopa Nonattainment Area (June 2014)” (“MAG 2014 Ozone Plan”), on which we previously deferred action.
