This property has a documented history as a bulk fuel distribution terminal predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.
The Clayton Bulk Plant operated as a fuel and heating oil bulk storage and distribution facility in Clayton, Stevens County, with four above-ground storage tanks and dedicated bulk loading and unloading areas on the same property as a defunct service station. Site Hazard Assessment worksheets from January 2007 documented petroleum-contaminated soil associated with the bulk storage loading and unloading areas and identified abandoned, out-of-service underground storage tanks containing aged gasoline. The assessor explicitly attributed the contamination to historical usage and practices at the site rather than any recent incident, and no active cleanup or remediation work has yet commenced. 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 aged gasoline found in those abandoned underground storage tanks and the petroleum-impacted soil throughout the bulk storage areas are the product of fueling and distribution operations that — by the assessor's own characterization — predate 1986. Occurrence-based CGL policies issued to bulk plant and service station operators during that pre-1986 window carried no effective pollution exclusion in Washington and remain enforceable today. The investigation and remediation costs this site now faces represent expenditures that historical carriers whose policies were in force during those earlier operations may be obligated to fund.
