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 — and recover costs already spent.
This property operated as a Chevron service station with underground storage tanks dispensing supreme unleaded, regular unleaded, and plus unleaded gasoline. A UST system retrofit and associated environmental investigation conducted in December 1996 revealed gasoline-range hydrocarbon and BTEX contamination, prompting excavation, off-site soil disposal, and product line trenching. Quarterly groundwater monitoring with activated-carbon treatment of purge water continues as part of the ongoing Standard Cleanup, alongside monitoring well abandonment and trench backfilling. 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 UST system at this Chevron station required a retrofit in 1996 — strong evidence that the tanks were installed and dispensing fuel well before 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The petroleum contamination discovered during that retrofit traces directly to those earlier decades of fuel storage and dispensing operations. Documented remediation expenditures to date — excavation, soil disposal, groundwater treatment, and years of quarterly monitoring — along with the costs of completing cleanup still ahead, represent obligations that historical CGL carriers may be required to fund.
