This property has a documented history as a gasoline service station going back to 1945. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property operated as an Exxon fueling station from 1945 through 1986, with seven underground storage tanks containing leaded gasoline, unleaded gasoline, diesel, used oil, and heating oil documented at the site. Remediation included the removal of five USTs in 1988, excavation and replacement of contaminated soil and rock on the driveway, and removal of two additional tanks — a 3,000-gallon gasoline tank and a 400-gallon heating oil tank — in 1991. Quarterly groundwater monitoring was conducted from April 2009 through May 2010, and cleanup work remains ongoing 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.
The contamination at this site traces directly to USTs installed and operated beginning in 1945 — more than four decades before 1986, the year occurrence-based Commercial General Liability policies began including effective pollution exclusions. Leaded gasoline and petroleum products stored in those tanks represent exactly the type of long-running, pre-cutoff release that pre-1986 CGL policies covered without restriction. The documented costs of UST removals, soil excavation, and years of groundwater monitoring represent expenditures that historical carriers whose policies were in force during the Exxon fueling station's operational life may be obligated to recover and to fund going forward.
