This property has a documented history as a gasoline service station going back to 1983. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.
This property has operated as a gasoline fueling station since at least 1983, when three 10,000-gallon single-walled fiberglass underground storage tanks and fuel dispensers were installed. Contamination was discovered in 1993, and subsequent investigations between 2006 and 2014 confirmed gasoline-range petroleum hydrocarbons, benzene, MTBE, diesel, and lead in soil and groundwater — the presence of lead indicating operations dating to the leaded-gasoline era. Cleanup under VCP and PTAP agreements has included excavation of contaminated soil, in-situ groundwater treatment via magnesium sulfate injection since 2012, and extensive groundwater monitoring, with independent remedial action continuing as of 2019. The site remains an active gas station with a convenience store. That history could support an insurance cost recovery claim against carriers who issued insurance policies 40+ years ago.
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 Washington. 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 contamination at this property traces to underground storage tanks installed and operated before 1986, during the period when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The presence of lead in soil samples confirms that fuel dispensing predates the phaseout of leaded gasoline, anchoring the contamination origin squarely within that pre-1986 policy window. More than two decades of documented remediation expenditures — site investigations, soil removal, groundwater injection treatment, long-term monitoring — represent costs that historical CGL carriers may be obligated both to reimburse and to continue funding as cleanup work proceeds.
