Rule Number: WY-23-19
Status: Scope statement approved in August 2019; DNR is currently drafting the proposed rule. Draft economic impact analysis (EIA) is expected in early 2021.
Scope Statement: SS 091-19 was approved by the governor in August 2019.
Summary: Revision of chapters NR 105, NR 106, and NR 219 and other related regulations to add surface water quality criteria and analytical methods for PFOS, PFOA, and any other PFAS for the purpose of protecting public health. Additionally, revisions to the procedures in the Wisconsin Pollutant Discharge Elimination System (WPDES) permitting program to implement the new water quality criteria, 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.
