Information for Tribes on Updates to the EPA's Interim Guidance on PFAS Destruction and Disposal (2024)
Sponsored by: U.S. EPA

In December 2020, the EPA issued its initial Interim Guidance on the Destruction and Disposal of Perfluoroalkyl and Polyfluoroalkyl Substances and Materials Containing Perfluoroalkyl and Polyfluoroalkyl Substances. The guidance generally describes available destruction & disposal technologies for PFAS-containing wastes with the potential to destroy PFAS or control PFAS release into the environment: interim storage, thermal treatment, landfilling, and underground injection. The EPA is updating the interim guidance with new information at least once every three years until final guidance is issued. The 2024 updated interim guidance is available here.
The interim guidance addresses destruction and disposal of PFAS and PFAS-containing materials including:
- Aqueous film-forming foam (for firefighting);
- Soil and biosolids;
- Textiles, other than consumer goods, treated with PFAS;
- Spent filters, membranes, resins, granular carbon, and other waste from water treatment;
- Landfill leachate containing PFAS; and
- Solid, liquid, or gas waste streams containing PFAS from facilities manufacturing or using PFAS.
This guidance is not intended to address destruction and disposal of PFAS-containing consumer products, such as non-stick cookware and water-resistant clothing.
The interim guidance provides managers of PFAS-containing wastes with tools, methods, and approaches for considering the impacts of potential releases on communities located near destruction and disposal facilities. It also includes testing and monitoring methods for detecting releases near these sites.
This webinar will focus on updates to the interim guidance including new science, emerging destruction technologies, and updated tools. The main presenters will be joined by subject matter experts from across EPA who will participate in the Q&A session.
EPA will accept comments on the updated Interim Guidance for 180 days following publication, and this overview may be useful to tribes in submitting comments. For more information on how the EPA is addressing PFAS, please see www.epa.gov/pfas.
