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.
This property at the intersection of Winslow Way W and Madison Ave N on Bainbridge Island is the site of a historical petroleum release linked to a leaking underground storage tank. Gasoline contamination in soil and groundwater was discovered in 1999 during sewer and waterline improvements, with TPH-Gx and BTEX compounds detected above Model Toxics Control Act cleanup levels. Remediation to date has involved excavation of petroleum-contaminated soils from utility trenches, off-site disposal, backfilling with clean soil, and environmental monitoring, but the site remains in awaiting-cleanup status under the Standard Cleanup program. 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 petroleum contamination here was already present underground when infrastructure crews uncovered it in 1999 — not the result of a recent spill but the legacy of historical fuel-storage operations predating 1986. Occurrence-based CGL policies in effect during those earlier decades of operation had no effective pollution exclusion under Washington law and remain enforceable today. The cleanup costs this property still faces — further investigation, remedial design, and full remediation of gasoline and BTEX contamination in soil and groundwater — could plausibly be funded by historical carriers whose policies were in force when the underground storage tanks were in active use.
