This property has a documented history as a gasoline service station predating 1986. Historical insurance policies issued during operations at this property and through 1986 could help fund the multi-phase investigation and remediation work ahead under Wisconsin DNR oversight.
This property operates as an active gas station in Ashland, with confirmed petroleum contamination in groundwater and the municipal storm sewer system. Although the current underground storage tanks were installed in 1993, an unrecorded pipe of unknown origin was discovered discharging petroleum into a municipal storm sewer catch basin — infrastructure that neither the city nor the site operator had any record of, strongly suggesting petroleum operations predating the current tank installation. MTBE has been detected in monitoring wells at concentrations exceeding Wisconsin DNR NR 140 preventive action limits, and petroleum has discharged into Bay City Creek via the storm sewer system. The site is an active Environmental Remediation Program case with ongoing groundwater investigation under Wisconsin DNR 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.
The discovery of unrecorded petroleum infrastructure at this property — including a pipe of unknown origin discharging into a municipal storm sewer catch basin — points to fueling operations conducted well before the current tanks were installed in 1993 and potentially predating 1986. The ongoing groundwater investigation, storm sewer remediation, MTBE contamination assessment, and long-term monitoring required under the Wisconsin DNR Environmental Remediation Program to protect Bay City Creek represent substantial future costs that historical pre-1986 carriers may be obligated to fund.
