Aqueous Film-Forming Foam Draft Environmental Impact Statement

Aqueous film-forming foam (AFFF) is a firefighting foam used to extinguish liquid-based fires—such as fires fueled by gasoline, oil, or chemicals. AFFF contains per- and polyfluoroalkyl substances (PFAS), which improve the foam’s heat resistance and ability to spread quickly over fire to suppress it. However, PFAS are toxic chemicals that can contaminate soil, surface water, groundwater, and drinking water if firefighting foam isn’t properly stored or cleaned up after use.  

 As directed by the Washington State Legislature, the Washington Department of Ecology (Ecology) is developing a AFFF collection program to assist fire departments with the proper disposal of unused PFAS-containing foam. As part of the collection program, Ecology prepared an draft Environmental Impact Statement (DEIS) to determine a feasible and safe way to dispose of AFFF. 

As part of the DEIS process, Ecology evaluated five options for the AFFF Collection and Disposal Program. Those disposal options include Approved Hold in Place, Incineration, Solidification and Landfill, Class 1 Deep Well Injection, and No Action.

We will review and respond to submitted comments. Substantive feedback will be incorporated into the final EIS. A final EIS will be issued and used to help select the foam disposal option. 

Comments that include the following are most helpful:

  • A reference to the DEIS section where your specific comments pertain.
  • Specific aspects of the DEIS you support or don’t support
  • Recommendations on how the DEIS could be improved or strengthened.
  • Suggestions on additional analysis needed or comments on the analysis that was completed. Clarification or correction of information.
  • Additional information including research, reports, and/or studies that will assist Ecology in the decision-making process.
