Maine
Planned / legislated- EPA set enforceable drinking-water limits for PFOA and PFOS at 4 parts per trillion (2024). A May 2026 proposal would keep those two, extend compliance to 2031, and rescind the others. Proposed, not final.
- Under CERCLA (the Comprehensive Environmental Response, Compensation, and Liability Act), PFOA and PFOS are hazardous substances, so cleanup liability is strict, retroactive, and joint and several.
- Federally required uses at Part 139 airports and military installations follow federal rules regardless of state law.
- The Department of Defense is phasing out AFFF under the NDAA.
Maine Revised Statutes Title 38 section 424-C (Class B foam PFAS ban, 2021) ↗
What's still allowed
AFFF sale/distribution has been restricted since 2022; Part 139 airport and military uses remain exempt. A statewide inventory runs (public entities by Nov 1, 2026; private by ~Nov 2027).
How to get rid of PFAS foam
No operational takeback yet, hold PFAS foam safely. Maine DEP must design and implement the take-back/disposal program by July 1, 2027 (contingent on appropriation).
Funding and help
There is no state takeback funding in Maine yet. The federal options below apply everywhere.
- EPA Emerging Contaminants in Small or Disadvantaged Communities grant ↗, funded by the Bipartisan Infrastructure Law.
- Drinking Water State Revolving Fund ↗, including the infrastructure-law set-aside for emerging contaminants like PFAS.
- FAA airport foam transition support ↗ for Part 139 commercial airports moving off fluorinated foam.
- Fire departments with contaminated water may qualify as claimants in the aqueous film-forming foam (AFFF) settlements.
Future plans
Program launch targeted for 2027; a DEP planning estimate puts ~50,000 gallons of AFFF stored statewide.
Destruction & vendors
No state-designated destruction vendor. Law on books but unfunded; ~50k gal is a DEP planning estimate, not collected.

Maine official program page ↗A note for smaller departments
Large departments and municipalities usually have legal counsel and a budget to manage PFAS liability. Small and volunteer departments often do not. That makes a documented chain of custody and a certificate of destruction the strongest protection a small department has: proof that the foam was handled lawfully and never released. See liability and litigation.
