MADISON, Wis. (AP) — Excessive compliance costs have forced Wisconsin regulators to stop developing groundwater standards on PFAS chemicals. Gov. Tony Evers said Tuesday that the Department of Natural Resources has had to stop drafting the standards because an economic impact projection put the cost of compliance for industrial facilities and wastewater treatment plants at $33 million over the first two years the standards would be in effect. Then-Republican Gov. Scott Walker signed a law in 2017 that requires state agencies obtain permission from legislators to continue working on regulations with compliance costs of at least $10 million over any two-year period.
