EPA Cracks Down on Stinky Dry Cleaning Pollution in Arizona
Published Date: 11/19/2025
Rule
Summary
The EPA just gave a thumbs-up to new rules in Maricopa County that cut down smelly and harmful chemicals from dry cleaners using petroleum solvents. This means cleaner air for folks in the area starting December 19, 2025, with businesses following updated guidelines to keep pollution in check. No big costs are expected, just a fresh breath of cleaner air!
Analyzed Economic Effects
3 provisions identified: 2 benefits, 1 costs, 0 mixed.
Dry cleaners now federally enforceable
Maricopa County Rule 333 (Petroleum Solvent Dry Cleaning), revised September 25, 2013, was approved into the Arizona SIP and becomes fully federally enforceable under Clean Air Act sections 110 and 113 as of December 19, 2025. Dry cleaning operations in Maricopa County that use petroleum solvents are therefore regulated under this federally-approved rule.
EPA: no big small-business burden
The EPA certified under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.) that this SIP approval does not have a significant economic impact on a substantial number of small entities. That means small business owners (including self-employed dry cleaners) are not expected to face a significant economic burden from this action.
Rule excludes Indian reservation lands
The SIP approval does not apply on any Indian reservation land or in any other area where the EPA or an Indian Tribe has demonstrated the Tribe has jurisdiction. In those areas of Indian country, the rule will not have Tribal implications and will not impose substantial direct costs on Tribal governments or preempt Tribal law.

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. This helps water providers get ready without rushing, keeping our drinking water safe. The EPA wants your thoughts and will hold a public hearing in July 2026 to hear from everyone.

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.
2026-09895 — Effluent Limitations Guidelines and Standards for the Steam Electric Power Generating Point Source Category-Unmanaged Combustion Residual Leachate

2026-09524 — Begin Actual Construction in the New Source Review (NSR) Preconstruction Permitting Program
The EPA is updating rules about when companies can start building big projects that might affect air quality. Now, they can begin building parts that don’t release pollution before getting a full air permit, making things clearer and easier. 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.
