This property has a documented history as a gasoline service station going back to 1946. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.
Kingston Lumber Supply operated a retail lumberyard at this property from 1946 until its closure in 2010, with records from 1975 documenting gasoline dispensing from a 500-gallon underground storage tank within the building — operations that pre-dated permitting and resulted in a dispensing violation. Diesel above-ground storage tanks were also in use from 1987 through 2010. The proposed cleanup plan calls for excavation and off-site disposal of an estimated 250 tons of impacted soil, pumping and disposal of 5,000 gallons of contaminated groundwater, at least one year of post-remediation groundwater monitoring, and a contaminated area currently remains capped by asphalt. Total estimated remediation costs, including contingency, are $150,000. 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 and above-ground fuel storage operations that were active well before 1986, the year occurrence-based Commercial General Liability policies effectively ceased to cover pollution claims. The gasoline UST documented in 1975 records — and the lumber supply operation itself dating to 1946 — fall squarely within the decades when historical carriers issued CGL policies without enforceable pollution exclusions. The $150,000 in projected remediation costs, covering soil excavation, groundwater recovery, and ongoing monitoring, represent expenditures that historical carriers whose policies were in force during that pre-1986 window may be obligated to fund.
