Michigan
Active program- 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.
Public Act 132 of 2020 (House Bill 4389) ↗
What's still allowed
Michigan restricts AFFF for training/calibration; Part 139 airport and military uses remain exempt.
How to get rid of PFAS foam
EGLE's AFFF Pickup & Disposal Program (running since 2019, free) is the route, but funding was exhausted in Oct 2025, so submissions are paused and EGLE keeps a waiting list. Hold foam until funding resumes.
Funding and help
Collection and destruction run through the Michigan program; check the official page for what the state covers.
- 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
~65,000 gallons collected through Nov 2023 (the largest state total); program awaits renewed funding.
Destruction & vendors
Foam in Michigan is handled by: Hazardous-waste disposal. Largest collected total of any state, but out of money; waiting list only.
Official sources
Michigan 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.
