This property has a documented history as a gasoline service station predating 1986. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.
This property operated as a Shell-branded gasoline station and car wash, with at least four single-walled steel underground storage tanks — two 12,000-gallon and two 10,000-gallon units holding gasoline and diesel — installed in 1980 and 1984, along with five additional tanks that were closed in place around 1985. A clay tile pipe uncovered during remediation indicates construction activity at the site predating 1960. Cleanup under Washington's Standard Cleanup program included excavation and removal of all four active USTs, five dispenser islands, and associated piping, along with removal of approximately 3,819 tons of petroleum hydrocarbon-impacted soil and on-site treatment of 293,286 gallons of contaminated groundwater through activated carbon filtration. Future groundwater monitoring remains required. 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 here originated from underground storage tanks installed and operated well before 1986, when occurrence-based Commercial General Liability policies lacked effective pollution exclusions — and physical evidence suggests the site's construction history extends as far back as the pre-1960 era. The documented remediation record — nearly 3,819 tons of impacted soil removed, nearly 300,000 gallons of groundwater treated, and long-term monitoring still ahead — represents both past expenditures and substantial future costs. Historical carriers who issued CGL policies to operators during those pre-1986 years may be obligated to recover cleanup costs already incurred and to fund the monitoring work that remains.
