EPA Tests Brand-New Bug-Killing Chemicals

2026-10086 — Extending the Compliance Deadline for the PFOA and PFOS Maximum Contaminant Levels

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.

2026-10085 — Rescission of Regulatory Determinations and Removal of Related Provisions for Four PFAS Substances (PFHxS, PFNA, HFPO-DA (GenX), and the Mixture of These Three PFAS Plus PFBS)

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

The EPA is updating rules for steam electric power plants to better control dirty water leaking from leftover coal waste. This change affects existing power plants and is expected to save up to $1 billion a year while protecting water quality. Comments on the proposal are open until June 17, 2026, so now’s the time to speak up!

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.

2026-08750 — Extension of Postponement of Effectiveness for Certain Provisions of Trichloroethylene (TCE); Regulation Under the Toxic Substances Control Act (TSCA)

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.

Previous: 2025-22934 — Request for Comments on the Renewal of a Previously Approved Information Collection: Requirements for Establishing U.S. Citizenship-46 CFR 355 and 356

The Maritime Administration wants to keep collecting info to check if people qualify as U.S. citizens for certain benefits. If you’re involved in maritime programs, this affects you! They’re asking for your thoughts by February 17, 2026, to make sure the process is clear and not too much work. No big changes or extra costs are planned—just a smooth renewal of the current rules.

Next: 2025-22936 — Appraisal Subcommittee Notice; Change of Address

Heads up! The Appraisal Subcommittee is moving its mailing address to 1717 K Street NW, Suite 900, Washington, DC, starting December 19, 2025. If you send mail or payments for National Registry invoices, make sure to use the new address to avoid delays. This change won’t affect phone or fax numbers, so keep those the same!
