This property has a documented history as a gasoline service station predating 1986. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.
This property has operated as a retail fuel facility — historically as a Cenex/Grange Supply site, now under the CHS brand — with multiple underground storage tanks holding unleaded gasoline, diesel variants, and kerosene, plus a fueling rack serving commercial and agricultural customers. Contamination originating from former tank areas designated A, B, and C pre-dates 1986; a Cleanup Action Plan was approved in 2000 to address that legacy release. Active remediation has included soil excavation, fuel recovery and LNAPL removal, an air sparging and soil vapor extraction system installed in 2001, and semiannual groundwater monitoring ongoing since at least 2017. The site continues to operate as a CHS retail fuel facility and True Value hardware store. 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 at this property traces directly to underground fuel storage and dispensing operations that were underway well before 1986, when occurrence-based Commercial General Liability policies had no effective pollution exclusion. Three named historical tank areas — A, B, and C — document a release timeline that predates modern policy language and has already required a formal Cleanup Action Plan, an engineered AS/SVE remediation system, recurring LNAPL recovery, and years of groundwater monitoring. Historical carriers who issued CGL policies to the facility operators during that pre-1986 window may still be obligated to fund both the remediation costs already incurred and those still ongoing.
