This Webinar is Restricted to Tribal environmental staff and community members

Under the National Defense Authorization Act for Fiscal Year 2020 (FY20 NDAA), the interim guidance generally describes thermal treatment, landfill and underground injection technologies that may be effective in the destruction or disposal of PFAS and PFAS-containing materials.

As required by the FY20 NDAA, the interim guidance addresses PFAS and PFAS-containing materials including:

  1. Aqueous film-forming foam (for firefighting);
  2. Soil and biosolids;
  3. Textiles, other than consumer goods, treated with PFAS;
  4. Spent filters, membranes, resins, granular carbon, and other waste from water treatment;
  5. Landfill leachate containing PFAS; and
  6. Solid, liquid, or gas waste streams containing PFAS from facilities manufacturing or using PFAS.
The interim guidance is not intended to address destruction and disposal of PFAS-containing consumer products, such as non-stick cookware and water-resistant clothing.

The agency is also providing guidance on testing and monitoring air, effluent, and soil for releases near potential destruction or disposal sites.

Because EPA will accept comments on the Interim Guidance until February 22nd, 2021, we wanted to provide an overview of the guidance that might be useful to tribes in submitting comments and outline what the guidance covers and what is not included. For more information, please see
