Department of Defense PFAS Discharge Prevention Act

This proposal would push the Department of Defense to better track and cut PFAS (“forever chemicals”) in stormwater that runs off its bases. Within one year, the department would have to ask states or the EPA to change existing stormwater permits (or plans) so they include regular PFAS testing—at least once every quarter—and require proven practices or technologies to reduce these chemicals in the water leaving military facilities.

It also sets a funding floor: at least 1% of the department’s PFAS cleanup money each year must go to testing stormwater at Defense sites, ensuring ongoing checks for contamination in runoff from bases.

• Who is affected: Department of Defense facilities and nearby communities concerned about water quality
• What changes: Quarterly PFAS monitoring in stormwater; required use of best practices or control technologies to reduce PFAS discharges; a minimum share of PFAS funds dedicated to stormwater testing
• When: The Defense Department must request permit changes within one year after the law takes effect; the 1% testing set‑aside applies each fiscal year
