What the agency says
The Environmental Protection Agency (EPA) is proposing to approve the State of Arizona's request to redesignate the Yuma nonattainment area from nonattainment to attainment for the 8-hour national ambient air quality standards (NAAQS or "standard") for ozone promulgated in 2015 ("2015 ozone NAAQS"). The EPA is also proposing to approve the "SIP Revision: 2015 Ozone NAAQS, Yuma Redesignation Request and Maintenance Plan" ("Yuma Maintenance Plan" or "Plan") as a revision to the State Implementation Plan (SIP) for the State of Arizona. The Yuma Maintenance Plan includes, among other elements, an emissions inventory consistent with attainment, a maintenance demonstration, contingency provisions, and a motor vehicle emissions budget for the first ten-year maintenance period. With this proposed rulemaking, the EPA is beginning the adequacy process for the 2020, 2030, and 2037 motor vehicle emissions budgets. The EPA is proposing these actions because this SIP revision meets the applicable Clean Air Act (CAA or "the Act") requirements for maintenance plans and because the State has met the requirements under the Act for redesignation of a nonattainment area to attainment with respect to the Yuma 2015 ozone NAAQS nonattainment area ("Yuma area").
