This property has a documented history as a property with a heating oil tank predating 1986. 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.
A 2,000-gallon steel fuel oil underground storage tank was removed from this mid-century commercial building in Sheboygan in November 2022, with corrosion identified as the cause of the release. Building features — including pneumatic tube tunnels, a basement vault, and an original oil-burning furnace later converted to gas — confirm pre-1986 construction and indicate the UST was an original fixture installed decades before 1986. Groundwater sampling at monitoring point P-1 detected ethylbenzene at 1.92 ppb, exceeding the NR 140 Preventive Action Limit of 0.5 ppb, and indoor air testing found naphthalene exceeding residential Vapor Action Levels on both the basement and first floors. Wisconsin DNR rejected a no-further-action recommendation and required full NR 726 closure, with site investigation ongoing. 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 underground storage tank removed from this property in November 2022 was an original fixture of the mid-century commercial building, confirming that fuel oil operations here began decades before 1986. The ongoing site investigation, groundwater monitoring at wells where ethylbenzene exceeds NR 140 Preventive Action Limits, indoor air vapor mitigation for naphthalene exceedances, and the full NR 726 closure process required by Wisconsin DNR represent future costs that historical pre-1986 carriers may be obligated to fund.
