EPA Approves Clean Air Status for Cleveland Area Under 2015 Ozone Standard

The Environmental Protection Agency has finalized a determination that the Cleveland, Ohio area meets the federal standard for ground-level ozone established in 2015. Based on air monitoring data from 2023 through 2025, the EPA considers the region to be in compliance with the 0.070 parts per million limit.
Why it matters: This is primarily an administrative update that shifts regulatory burden. Ohio will no longer need to draft and submit ozone-specific air quality planning documents for the Cleveland area under the 2015 standard. If air quality worsens and violates the standard again, the EPA can reinstate those planning requirements.
