This property has a documented history as a gasoline service station predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.
Ross Plaza Lot 13 was formerly occupied by a gasoline service station constructed as part of the Ross Plaza development in the late 1970s and early 1980s, predating 1986. Aged total petroleum hydrocarbons as gasoline (TPH-G) were detected in soil and groundwater during site investigations, and the contamination was determined to require further remedial action. The site has been subject to regulatory oversight under both the Independent Remedial Action Program and the Voluntary Cleanup Program since at least 1997; the property is currently occupied by a Seafirst National Bank branch and active cleanup has not yet commenced. 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 gasoline contamination at this property traces to a service station that operated during the late 1970s and early 1980s, when occurrence-based Commercial General Liability policies had no effective pollution exclusion under Washington law. Because remediation has not yet begun, the costs ahead — soil and groundwater treatment, long-term monitoring, and regulatory closure — are exactly the type of expenditures that historical carriers whose CGL policies were in force during those pre-1986 operating years may be obligated to fund. The documented TPH-G contamination and the site's long regulatory history establish the factual predicate for pursuing those historical policies before cleanup costs are incurred.
