EPA Rule Undone: Congress Eases Polluter Limits Overnight
Published Date: 1/2/2026
Rule
Summary
The EPA is undoing a 2024 rule that made some big polluters keep stricter pollution limits even if they got reclassified as smaller sources. Thanks to Congress and the President, the old 2020 rules are back in charge starting January 2, 2026. This change mainly affects companies handling certain hazardous pollutants, easing their compliance rules and possibly saving them money and hassle.
Analyzed Economic Effects
2 provisions identified: 2 benefits, 0 costs, 0 mixed.
Estimated $935.8M regulatory savings
The EPA estimates the present value (PV) of regulatory cost savings beginning in 2025 is $935.8 million (in 2024 dollars, discounted to 2024) using a 7% discount rate, with an equivalent annual value (EAV) of $65.5 million (in 2024 dollars). These are EPA's aggregated estimated cost savings tied to removing the 2024 Rule.
Easier reclassification for major HAP sources
The EPA is undoing the 2024 change and restoring the November 19, 2020 rule so that major sources of hazardous air pollutants (HAP) can reclassify as area sources and avoid remaining subject to major-source NESHAP in many cases. The 2024 Rule had required sources for seven specific persistent and bioaccumulative HAP to stay under major-source standards; that requirement is removed effective January 2, 2026, which eases compliance and may save regulated companies money and paperwork.

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. This means businesses and cleanup crews won’t have to deal with the confusing new rules that were proposed. 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.
