This property has a documented history as a gasoline service station going back to 1946. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property has operated as a gas station and general store since at least 1946. Two steel underground storage tanks installed in 1974 remained in service until 1995, when they were upgraded with new tanks; during that replacement work, petroleum contamination was discovered in the surrounding soils. Cleanup under the Standard Cleanup program has included removal and disposal of the two original USTs, excavation of 152 cubic yards of petroleum-contaminated soil hauled offsite for aeration, backfilling and asphalt capping of the excavation, and long-term monitoring of the stockpiled soil. 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.
Gas station operations at this property date to 1946 — four decades before occurrence-based Commercial General Liability policies gave way to claims-made forms with pollution exclusions in 1986. The petroleum release discovered in 1995 is tied directly to underground storage infrastructure that served those pre-1986 operations, and the documented remediation costs — tank removal, soil excavation, offsite treatment, and ongoing monitoring — are the type of cleanup expenditures that historical CGL carriers may be obligated both to recover and to fund going forward.
