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 was developed in 1945 as a gasoline service station with automotive repair bays, operating one diesel and three gasoline underground storage tanks until the late 1980s. The USTs were closed in place between 1988 and 1991 and subsequently removed in 2011, at which point contamination from leaking tanks was confirmed. Multi-year groundwater monitoring has continued since, with the most recent sampling event in March 2023, and cleanup remains 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 underground storage tanks at this property were installed and operated beginning in 1945 — more than four decades before the 1986 shift away from occurrence-based Commercial General Liability policies that lacked effective pollution exclusions. Petroleum contamination confirmed during the 2011 tank removal traces directly to releases during that extended pre-1986 operational window. Historical CGL carriers whose policies were in force while this service station operated may bear obligations both to recover documented remediation expenditures and to fund the continuing groundwater monitoring and any future cleanup work required.
