EPA Greenlights Ohio's Ozone Control Measures for Cleaner Air

## Summary

The EPA is giving a thumbs-up to Ohio’s updated air pollution rules that help cut smog-causing chemicals in several counties, including Cleveland and Cincinnati areas. These changes make the air cleaner by controlling certain emissions and will officially start on February 19, 2026. Businesses and communities in these counties will see clearer skies without new costs or delays.

## Abstract

The Environmental Protection Agency (EPA) is approving revisions to Ohio Administrative Code (OAC) Chapters 3745-21 and 3745- 110 into the Ohio State Implementation Plan (SIP). The Ohio Environmental Protection Agency ("Ohio" or "Ohio EPA") submitted these revisions on March 30, 2022, and supplemented the submittal on February 1, 2023, and August 28, 2023. The EPA is approving parts of OAC Chapters 3745-21 and 3745-110 as satisfying some of the Moderate Volatile Organic Compound (VOC) Reasonably Available Control Technology (RACT) and Nitrogen Oxide (NO<INF>X</INF>) RACT requirements for the Cleveland, OH nonattainment area (Cuyahoga, Geauga, Lake, Lorain, Medina, Portage, and Summit counties) under the 2015 ozone National Ambient Air Quality Standard ("NAAQS" or "standard") and as SIP strengthening for Ashtabula County and the Ohio portion of the Cincinnati, OH-KY maintenance area (Butler, Clermont, Hamilton, and Warren counties). The EPA is also approving Table (M)(1) in OAC rule 3745-21-07 into the SIP, with the exception of the row for The Ruscoe Company. Finally, the EPA is approving OAC rule 3745-15-03, submitted by Ohio on February 9, 2023, and supplemented on December 1, 2023, and December 30, 2024. The EPA proposed to approve this action on August 28, 2025 and received two comments.

## Effects PRIA read

- Ohio RACT Rules Approved for Ozone: benefit, low. The EPA approved parts of Ohio Administrative Code Chapters 3745-21 and 3745-110 as meeting Reasonably Available Control Technology (RACT) for the 2015 ozone standard for the Cleveland nonattainment area (Cuyahoga, Geauga, Lake, Lorain, Medina, Portage, and Summit counties). The EPA also approved t…
- State Reporting Rule Approved: cost, low. The EPA approved OAC rule 3745-15-03, which sets reporting requirements for sources in Ohio, and the approval is effective February 19, 2026. The rule is incorporated into the State Implementation Plan (SIP) and applies to sources in Ohio.
- Ohio Rules Become Federally Enforceable: cost, low. The Ohio regulations approved into the SIP are "fully federally enforceable under sections 110 and 113 of the Clean Air Act" as of the final rule's effective date, February 19, 2026. That means federal enforcement can be applied to the approved Ohio rules starting on that date.
- Ruscoe Plant II Excluded From SIP Table: benefit, low. The EPA approved Table (M)(1) in OAC rule 3745-21-07 into the SIP but excluded the row for "TRC Buyer Co. dba 'The Ruscoe Company' Plant II" (facility ID 1677010204). The table regulates facilities using liquid organic materials and requires at least 85% VOC control efficiency for listed emissions…
