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 recover the cleanup costs already paid.
This public street intersection in Mount Vernon was listed by Washington State Ecology in 1991 after petroleum contamination originating from the adjacent former Chevron Bulk Plant was found to have migrated onto neighboring properties, including the city-owned right-of-way. Cleanup activities on the Chevron Bulk Plant site ran from 1989 through 1996, encompassing general soil remediation, targeted soil excavation including distinct excavation areas documented in a site map, and groundwater monitoring through a network of wells sampled periodically before decommissioning in 1996. The site has since received a No Further Action determination. 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 intersection originated from bulk plant operations that had been underway for years before 1986 — the release was substantial enough to require soil remediation beginning in 1989 and to trigger a regulatory listing in 1991, a timeline consistent with prolonged pre-1986 accumulation rather than a discrete recent event. Occurrence-based CGL policies issued to the Chevron bulk plant operators during that pre-1986 window carried no effective pollution exclusion and remain potentially enforceable today. The documented cleanup expenditures from 1989 through 1996 — soil remediation, excavation, and multi-year groundwater monitoring — represent costs that historical carriers may be obligated to recover.
Restorical's role is to locate viable historical policies, determine whether a successful cost recovery claim is possible, and assist our clients and their legal counsel to obtain insurance coverage for costs already incurred. Restorical's forensic accounting team works to re-establish and document past cleanup expenditures, ensuring the strongest possible basis for recovery.
Recovering Costs from an Older Cleanup
If this site reached No Further Action years ago, the original cleanup expenditures may be difficult to reconstruct. Restorical's forensic accounting team specializes in re-establishing and documenting past cleanup costs — even decades later — to build the strongest possible basis for an insurance recovery claim.
