This property has a documented history as a gasoline service station going back to 1984. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property was developed as a retail gasoline station in 1984, operating four 10,000-gallon underground storage tanks and four dispenser islands for the distribution of leaded and unleaded gasoline until 2005. Cleanup under the Voluntary Cleanup Program has been ongoing since at least 1992 and has included multiple phases of UST removal and soil excavation — over 500 cubic yards and 784 tons of contaminated soil removed — along with operation of Soil Vapor Extraction and Air Sparge systems, bioventing, vapor barrier installation, and subsurface injection of 35,500 gallons of sulfate and persulfate solutions for groundwater treatment. Monitored natural attenuation and institutional controls are planned as next steps. 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 beginning in 1984, when occurrence-based Commercial General Liability policies were still the industry standard and carried no effective pollution exclusion in Washington. More than three decades of documented remediation expenditures — tank removals, large-scale soil excavation, vapor extraction, air sparging, chemical injection campaigns, and continuous groundwater monitoring — were incurred to address releases tied to those pre-1986 operations. The historical carriers who issued CGL policies during that window may be obligated both to recover past cleanup costs and to fund the remediation work still ahead.
