This property has a documented history as a gasoline service station going back to 1920. 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 gasoline service station from approximately 1920 until the 1950s and then as an auto body repair shop through the 1990s. Cleanup under the Voluntary Cleanup Program has included the removal of five underground storage tanks — two gasoline USTs, one heating oil tank, and two additional gasoline USTs discovered during excavation — along with 1,203 tons of contaminated soil removed in 2008 and 2010. A regulatory variance was approved in 2021 for residual soil contamination in the right-of-way, and quarterly groundwater monitoring has continued through 2023. 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 as early as the 1920s, more than six decades before occurrence-based CGL policies gave way to claims-made forms with pollution exclusions. The documented remediation expenditures — tank removals, large-scale soil excavation, well installations, and years of ongoing groundwater monitoring — were incurred to address releases tied directly to those pre-1986 fueling operations. Historical carriers who issued CGL policies covering the service station during its decades of operation may still be obligated to recover those costs and to fund the remaining cleanup work.
