This property has a documented history as a bulk fuel distribution terminal going back to 1950. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property operated as a Chevron bulk plant and heating oil distribution facility from approximately 1950 to 1975, with multiple 12,000-gallon underground storage tanks for diesel and a 500-gallon gasoline tank installed circa 1950. Cleanup under the Voluntary Cleanup Program has included the removal of four underground storage tanks and closure-in-place of a fifth, along with identification of contaminated soil slated for future removal. Quarterly groundwater monitoring from 2008 through 2014 involved purging and treating well water through granular activated carbon. Cleanup work 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.
Petroleum contamination at this site traces to bulk plant operations and underground storage tanks that were installed and operated for a quarter century before 1986, when occurrence-based CGL policies carried no effective pollution exclusion in Washington. The presence of leaded gasoline — confirmed by Total Lead analysis of a 1950-era tank — and decades of diesel storage represent the kind of long-duration releases these policies were written to cover. Documented remediation costs to date — tank removals, groundwater treatment, long-term monitoring — along with the soil removal still ahead, represent expenditures that historical carriers may be obligated both to reimburse and to fund going forward.
