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 — and recover costs already spent.
The 7th Ave Plaza Drainage Swale was contaminated by petroleum discharges from the adjacent Unocal Bulk Plant 0206, whose oil/water separator and drain line extend beneath the 7th Avenue Plaza parking lot and discharge at the head of the swale. Washington Public Works identified the Union Oil distributor as a likely contributor to the swale's elevated TPH concentrations. Partial remediation in 1991–1992 involved excavation and off-site disposal of approximately 60 cubic yards of petroleum-impacted soil, surface water diversion, backfilling, topsoil placement, and revegetation; a 2021 assessment documented remaining contamination, and cleanup is ongoing. 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 here — TPH, diesel, heavy oil, gasoline, and hydraulic fluid — originated from chronic operational discharges at a bulk fuel distribution facility active well before 1986, not from a discrete spill event. Occurrence-based CGL policies issued to facility operators during that pre-1986 window had no effective pollution exclusion and remain enforceable against the gradual, continuous releases that characterize bulk-plant runoff. The documented remediation expenditures — soil excavation and disposal, site restoration, and a 2021 follow-on assessment — represent costs that historical carriers may be obligated both to recover and to fund going forward.
Restorical's role is to locate viable historical policies, determine whether a successful coverage claim is possible, and assist our clients and their legal counsel to obtain insurance coverage.
