This property operated as UNOCAL Service Station 5004 in Bellevue from approximately 1962, with two fuel service islands, three underground steel fuel storage tanks (two at 7,500-gallon capacity and one at 10,000 gallons), a 280-gallon waste oil tank, and service bays equipped with hydraulic lifts. Between May 1990 and May 1991, cleanup activities removed the underground storage tanks, product lines, hydraulic lifts, and approximately 2,160 cubic yards of contaminated soil, with material treated on-site or disposed off-site. A vapor extraction system was then installed and operated from May 1992 through August 1993 to remediate remaining soil contamination. Cleanup work is ongoing under the Standard Cleanup program. That history could support an insurance cost recovery claim against carriers who issued insurance policies 40+ years ago.
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.
Petroleum contamination at this site originated from fuel storage and dispensing infrastructure installed around 1962 — more than two decades before occurrence-based Commercial General Liability policies ceased reliably covering pollution claims in 1986. The documented remediation expenditures here — tank and soil removal across thousands of cubic yards, plus over a year of vapor extraction operations — represent substantial cleanup costs tied directly to those pre-1986 fueling operations. Historical carriers who issued CGL policies to UNOCAL during that operational window may be obligated both to recover costs already incurred and to fund the cleanup work that remains.
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. Restorical then manages the claim, including accounting, to ensure the cleanup is funded in a timely manner.
