This property has a documented history as a gasoline service station predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property contained an abandoned 780-gallon underground gasoline storage tank that was unearthed during a State Route 99 stormwater and pedestrian improvement project. Cleanup activities included hydro-excavation and removal of the UST, off-site disposal of 275 gallons of sand and 330 gallons of water pumped from the tank, and off-site cleaning and disposal of the tank itself. Contaminated soil remains in place, and the site is awaiting further remediation under the Standard Cleanup program. 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.
Lead detected above cleanup levels in groundwater at this property is a direct marker of pre-1986 operations — leaded gasoline was phased out before that year, meaning the release that produced this contamination originated during the era when occurrence-based Commercial General Liability policies were still the industry standard and carried no effective pollution exclusion. Those historical carriers may still be obligated to respond to the documented costs of UST removal and contaminated-media disposal already incurred, as well as the soil remediation expenditures that lie ahead.
