This property has a documented history as a public works and maintenance facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.
This property served as the City of Mercer Island Fire Department's fueling facility, where a former underground storage tank left behind soil contamination and free product that persisted even after the site was initially designated as Reported Cleaned Up. The RCU designation proved premature — contamination above state standards remained within the former UST excavation, and groundwater at the site was never assessed. The site has since been reclassified into Washington's Standard Cleanup program and remains awaiting active remediation, with grants of $200,000 to $300,000 available to local governments to offset future cleanup costs. 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 prior Reported Cleaned Up designation — later reversed when soil contamination and free product were found still present and groundwater was left entirely unassessed — means the full extent of the release at this site remains unknown, and future remediation costs have not yet been quantified. That open groundwater question represents a liability whose scope is still uncharted. Occurrence-based CGL policies issued to the City of Mercer Island during the years this tank was in service may be enforceable against the remediation costs still ahead, because the contamination event giving rise to those costs occurred during their coverage period.
