Rule Number: WY-23-19
Status: Scope statement approved in fall 2019; DNR is drafting the proposed rule. Draft economic impact analysis (EIA) is expected in early 2021.
Scope Statement Summary: Under the scope statement, DNR could also change Wisconsin Pollution Discharge Elimination System (WPDES) permit implementation procedures related to PFAS chemicals, including additional monitoring and new effluent limitations. Currently, DNR can address PFAS discharges in WPDES permits on a case-by-case basis. The proposed rule would set a uniform standard and procedures.
