Environmental Protection Agency
The Environmental Protection Agency (EPA) is proposing to act in accordance with a request from the Ohio Environmental Protection Agency (Ohio EPA) to redesignate the Cleveland, Ohio area to attainment for the 2015 ozone National Ambient Air Quality Standards (NAAQS) because the request meets the statutory requirements for redesignation under the Clean Air Act (CAA). The Cleveland area includes Cuyahoga, Geauga, Lake, Lorain, Medina, Portage, and Summit Counties. Ohio EPA submitted this request on December 8, 2025. The EPA is also proposing to approve, as a revision to the Ohio State Implementation Plan (SIP), the State's plan for maintaining the 2015 ozone NAAQS through 2038 in the Cleveland area. The EPA is also initiating the adequacy process and proposing to approve Ohio's 2032 and 2038 volatile organic compound (VOC) and oxides of nitrogen (NO<INF>X</INF>) motor vehicle emissions budgets (budgets) for the Cleveland area. Additionally, the EPA is proposing to adjust the deadline for Ohio to submit Serious SIP revisions for the Cleveland area. Finally, the EPA is proposing to approve the Enhanced motor vehicle inspection and maintenance (I/M) program certification, clean fuel vehicle program (CFVP) certification, and enhanced monitoring plan (EMP) certification SIP revisions submitted by Ohio EPA on December 19, 2025, and January 12, 2026, pursuant to section 110 and part D of the CAA, because they satisfy Serious SIP requirements for the Cleveland area under the 2015 ozone NAAQS.
