This property has a documented history as an industrial and manufacturing facility going back to 1890. Historical insurance policies issued during those prior operations and through 1986 could help fund the ongoing cleanup and groundwater monitoring obligations that Wisconsin DNR continues to oversee.
This property has been in commercial and industrial use since before 1890, with documented pre-1986 operations including a gasoline filling station, a dry-cleaning facility active through the 1960s, a machine shop and metal stamping operation, a bakery, and an auto repair shop. Corroded fuel oil underground storage tanks were discovered during a 2009 tank closure assessment, and a Phase II investigation in 2022 confirmed volatile organic compounds exceeding Wisconsin DNR NR 140 enforcement standards in four of eleven monitoring wells — including trichloroethylene (TCE), cis-1,2-dichloroethene, vinyl chloride, MTBE, and benzene. The groundwater plume has migrated off-site and flows toward the Fox River and Lake Winnebago, and a site investigation work plan was submitted in 2026 to guide further characterization under Wisconsin DNR LUST program oversight. That history could support an insurance coverage claim against the carriers who issued policies more than 40 years ago — coverage that could help fund the cleanup ahead.
Why Historical Insurance Policies May Be Accessible
Pre-1986 Commercial General Liability (CGL) policies were occurrence-based and did not contain an effective pollution exclusion in Wisconsin — and those policies may provide coverage that remains enforceable today. If contamination occurred while those policies were active, those historical insurance carriers may still have a legal obligation to fund the cleanup costs, even if the business closed or the property changed hands.
Commercial and industrial operations at this property — gasoline fueling, dry cleaning, metal degreasing, and other industrial activities — date back more than a century before 1986, placing the contaminating operations squarely in the pre-1986 window. The ongoing site investigation, groundwater remediation, off-site plume management, and long-term monitoring required to reach Wisconsin DNR closure represent future costs that those historical carriers may be obligated to fund.
