This property has a documented history as a gasoline service station going back to 1957. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property hosted a gasoline service station on its southwest portion from at least 1957 through 1969, with five gasoline underground storage tanks and one waste oil UST that remained in place until their removal in 1991. Cleanup under the Voluntary Cleanup Program has been ongoing since at least 2015, encompassing multiple phases of UST and contaminated soil excavation — approximately 330 cubic yards removed in a single event — as well as groundwater monitoring, light non-aqueous phase liquid (LNAPL) recovery, and well development with purging. Investigation and remediation activities continue, including soil and groundwater sampling, boring abandonment, well decommissioning, and investigation-derived waste disposal. 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.
The petroleum contamination at this property traces directly to underground storage tanks installed and operated beginning in 1957 — nearly three decades before 1986, when occurrence-based Commercial General Liability policies were still the industry standard and lacked an effective pollution exclusion in Washington. The documented remediation expenditures here — soil excavation, LNAPL recovery, multi-year groundwater monitoring, and ongoing investigation — are the direct consequence of releases from those pre-1986 operations. Historical carriers who wrote CGL policies during the service station's operational window may be obligated both to recover the cleanup costs already incurred and to fund the remediation work that remains ahead.
