Wisconsin DOJ Announces $200,000 Settlement With Neenah Foundry Company for Alleged Air Pollution Violations
MADISON, Wis. – The Wisconsin Department of Justice (DOJ) today announced a $200,000 settlement with Neenah Foundry Company. The settlement resolves a civil environmental enforcement action alleging violations of air pollution control permits and Wisconsin Department of Natural Resources (DNR) and U.S. Environmental Protection Agency (EPA) regulations for the company’s two foundry plants in Winnebago County, Wisconsin.
“Our air pollution control permit system relies on compliance with permit terms in order to effectively protect clean air,” said Attorney General Kaul. “When companies fail to fulfill their obligations under those permits, there must be accountability.”
The State’s Complaint contains 18 total alleged violations related to the company’s alleged failures to maintain and operate air pollution control devices and monitors, alleged inadequate recordkeeping, and alleged failures to report deviations from permit requirements to DNR.
Ten of the alleged violations are for allegedly failing to maintain minimum air pressures, pressure differentials, water pressures, water and scrubber flow rates, and temperatures necessary of the control devices to operate properly. Another two alleged violations are for allegedly failing to maintain output analyses of the control devices. One alleged violation is for allegedly failing to maintain records on leak alarms on control equipment. Two alleged violations are for allegedly failing to timely submit documents about the proper operation of control devices. Another alleged violation is for allegedly failing to perform yearly calibrations of an air pollution monitor. An additional alleged violation is for allegedly failing to maintain a log of steps taken to control dust. And one alleged violation is for an alleged failure to notify DNR of deviations from permit requirements.
The proposed agreement requires the company to pay a total of $200,000 in forfeitures, surcharges, and court costs. The Order for Judgment was signed by Winnebago County Circuit Court Judge Bryan Keberlein on May 7, 2026.
Wisconsin DOJ worked closely with the Wisconsin Department of Natural Resources to obtain this result.
