This property served as a Northwest Airlines bulk fuel farm and aircraft maintenance facility at Seattle-Tacoma International Airport, with underground storage tanks installed as early as the late 1940s. Cleanup activities have included the removal of multiple underground storage tanks in 1990 and 1991, excavation and off-site disposal of approximately 125 cubic yards of impacted soil, operation of a soil vapor extraction system from 1992 to 1996, and ongoing passive product recovery and groundwater monitoring extending into 2000. Sampling at the former bulk fuel farm area documented extremely elevated concentrations of jet fuel (TPH as Jet A) in groundwater, and remediation efforts remain underway. 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.
The petroleum contamination at this site originated from bulk aviation fuel storage infrastructure installed more than three decades before 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The documented remediation expenditures — tank removals, soil excavation, four years of vapor extraction, and long-term groundwater monitoring and product recovery — represent costs tied directly to those pre-1986 fueling operations. Historical carriers who issued CGL policies to the facility operators during that window may be obligated both to reimburse past cleanup costs and to fund the remediation work that continues.
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.
