MN SF4207

Minnesota Pollution Control Agency commissioner must identify emerging PFAS chemicals measured in influent, effluent, sewage sludge, surface water, aquatic sediments, and freshwater fish that may pose risks to human health or ecological functions based on toxicity, persistence, and bioaccumulation potential.

Commissioner must submit reports to legislative environment committees every three years listing identified PFAS, supporting data, and risk assessment processes, timed to coincide with the federal triennial water quality standards review.

By January 1, 2028, the agency must develop a protocol for managing priority PFAS through site-specific water quality criteria, statewide standards, or effluent limitations, with costs placed on pollution originators.

Draft PFAS management protocol must be posted for 60 days of public comment with at least one public informational meeting before finalization.

Commissioner must adopt water quality standards for PFOA and PFOS applicable to class 2 waters by January 1, 2028, with the standard 18-month rulemaking deadline waived.
