This property operated as a petroleum service station with underground storage tanks well before 1986, as confirmed by the presence of lined steel USTs with fiberglass piping consistent with that era of installation. Historic soil borings conducted between 2003 and 2008 revealed significant petroleum contamination at depth, and a prior LUST case at this location was closed with residual groundwater contamination still present. A subsequent tank system site assessment found soil concentrations of benzene, ethylbenzene, naphthalene, trimethylbenzenes, and xylenes exceeding Wisconsin DNR NR 720 groundwater pathway protection residual contaminant levels, and the site remains an open LUST case 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.
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.
Petroleum fueling operations at this property began decades before 1986, as evidenced by lined steel underground storage tanks with fiberglass piping consistent with that era and by historic soil borings conducted between 2003 and 2008 that revealed significant petroleum contamination at depth. The ongoing soil and groundwater investigation, remediation of benzene, ethylbenzene, naphthalene, trimethylbenzenes, and xylenes exceeding Wisconsin DNR NR 720 residual contaminant levels, and long-term monitoring required to achieve LUST case closure represent future costs that historical pre-1986 carriers may be obligated to fund.
