Environmental Protection Agency
The Environmental Protection Agency (EPA) is proposing to determine under the Clean Air Act (CAA) that the Cleveland, Ohio nonattainment area (hereafter also referred to as "Cleveland area" or "area") has attained the 2015 ozone National Ambient Air Quality Standard (NAAQS or standard). This determination is based upon complete, quality-assured, and certified ambient air monitoring data for the 2023-2025 design period showing that the Cleveland area achieved attainment of the 2015 ozone NAAQS. This determination relies on an exceptional events request submitted by the Ohio Environmental Protection Agency (Ohio EPA) on December 8, 2025, which the EPA concurred with on January 12, 2026. The EPA is proposing to take final agency action on Ohio's exceptional events request and the EPA's concurrence. As a result of this determination, the EPA is proposing to suspend the requirements for the state to submit an attainment demonstration and associated Reasonable Available Control Measures (RACM), Reasonable Further Progress (RFP) plans, contingency measures for failure to attain or make reasonable progress, and other planning State Implementation Plans (SIPs) related to attainment of the 2015 NAAQS, for as long as the Cleveland area continues to attain the 2015 ozone NAAQS.
