This property has a documented history as a public works and maintenance facility going back to 1976. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
King County's Police Precinct 2 in Kenmore operated a 10,000-gallon steel underground storage tank, installed by King County in 1976, to supply unleaded gasoline for municipal fleet vehicles. The UST was taken out of service in 1990, and remediation included its removal, overexcavation of approximately 1,000 cubic yards of petroleum-contaminated soil, and management of that material through stockpiling, off-site disposal, and clean-soil backfill. Approximately 30,000 gallons of groundwater were extracted from the excavation, treated by aeration in a temporary holding pond, and discharged through an on-site infiltration system. Cleanup at the site is ongoing. 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 release here traces directly to a government fleet-fueling UST installed in 1976 and operated for more than a decade before 1986, when occurrence-based Commercial General Liability policies still carried no effective pollution exclusion. The documented remediation record — UST removal, excavation of 1,000 cubic yards of contaminated soil, and extraction and treatment of 30,000 gallons of affected groundwater — establishes a concrete expenditure trail tied to that pre-1986 release. Historical carriers that issued CGL policies to King County during the UST's operational window may be obligated both to recover those documented costs and to fund the site's remaining cleanup obligations.
