The state Department of Natural Resources policy board is set to vote later this month on permanent rules implementing a law that restricts the use of firefighting foam that contains PFAS chemicals.
Gov. Tony Evers signed a bill in 2020 that prohibits the use of foam that contains PFAS except in emergency situations and for testing, and then only if it can be disposed of or stored without seeping into the environment.
The DNR estimates the rules could cost facilities that use foam for emergencies or testing a total of $600,000 to $4 million annually, although costs could shrink over time as facilities use replacement foam or other methods.
The board is set to vote on the rules Jan. 26.
