Ohio air rules become federally enforceable
EPA is approving amendments to Ohio Administrative Code Chapter 3745-25 into Ohio's State Implementation Plan (SIP), and these approved rules become federally enforceable under Clean Air Act sections 110 and 113 as of January 26, 2026. EPA will finalize this effective date unless it receives adverse comments by December 26, 2025.
Only minor clerical edits — no new costs
Ohio's amendments correct typographical errors, update publication titles, dates, and addresses, and make style and formatting changes; they do not revise emission limits, change emission standards, or alter the scope or intent of the rules. EPA certified the action as not having a significant economic impact on a substantial number of small entities.
Does not apply to tribal jurisdiction
EPA's approval of these Ohio SIP revisions is not approved to apply on any Indian reservation land or in any other area where EPA or an Indian Tribe has demonstrated that a Tribe has jurisdiction. Those areas remain outside the scope of this SIP approval.

The EPA is giving water systems more time to meet safety rules for two harmful chemicals, PFOA and PFOS, by extending the deadline from April 2029 to April 2031 if they ask for it.

The EPA is proposing to undo its rules for four PFAS chemicals (PFHxS, PFNA, GenX, and a mix including PFBS) in drinking water because the original process wasn’t done right. This means public water systems won’t have to monitor or treat these chemicals for now. People and water providers should weigh in by July 20, 2026, and a virtual hearing happens July 7.

This change mainly affects businesses planning major construction and could speed up projects without extra costs, but comments are due by June 29, 2026.
2026-09179 — Definition of Hazardous Waste Applicable to Corrective Action for Releases From Solid Waste Management Units; Withdrawal
The EPA has decided to cancel its plan to change the rules about what counts as hazardous waste for cleaning up pollution at certain waste sites.

The withdrawal takes effect immediately, so no extra costs or changes will happen right now.

The EPA is hitting the pause button again on some rules about a chemical called TCE, which is used in workplaces. This means certain limited uses of TCE won’t have to follow new restrictions just yet, while courts review the rules. If you work with TCE, this delay gives you more time before changes kick in, starting May 18, 2026.
