This property has a documented history as a gasoline service station going back to 1969. 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 gasoline service station with underground storage tanks containing gasoline, heating oil, and used oil, with operations documented as early as 1969 and a service station present on the site before that date. Cleanup under the Standard Cleanup program has included excavation of 16 underground storage tanks, hydraulic hoists, and a sump pump, removal of over 2,000 cubic yards of contaminated soil, and treatment of 233,000 gallons of petroleum-affected groundwater. Remediation has spanned multiple years with long-term monitoring and site paving for containment, and additional cleanup costs for potential soil and tank removal are still anticipated. 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 originated from underground storage tanks installed and operated well before 1986, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion in Washington. The scale of documented remediation — 16 tank removals, thousands of cubic yards of soil excavation, hundreds of thousands of gallons of groundwater treatment, and ongoing monitoring — represents substantial expenditures that historical carriers may be obligated to recover, with additional cleanup costs still ahead. Policies issued to the operators during the pre-1986 window when these tanks were in active service remain a plausible source of both reimbursement and forward-looking coverage.
