Gas Station cleanup site — Restorical Research
Seattle Freight Terminal
Seattle, King County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1947. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

The Seattle Freight Terminal property was the location of a former 'Oil and Gas' service station documented on Sanborn maps, with the facility building dating to 1947. Remediation has included excavation of approximately 418 tons of petroleum-impacted soil and 1,550 gallons of affected groundwater across two site areas, removal of an abandoned 500-gallon lube oil UST from which 200 gallons of residual product were recovered, and in-situ groundwater treatment using 20,310 gallons of PetroFix. Quarterly groundwater monitoring is ongoing as cleanup work continues. 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 detection of 1,2-dichloroethane (EDC) in groundwater — a documented additive to leaded gasoline — directly ties the contamination at this site to gasoline dispensing operations conducted during the era when occurrence-based CGL policies were standard and contained no effective pollution exclusion. With the facility building itself dating to 1947, the service station's operational years fall squarely within that pre-1986 window. The documented remediation expenditures — UST removal, multi-area soil excavation, chemical injection treatment, and ongoing monitoring — represent costs that historical carriers whose policies were in force during those operating years may be obligated both to recover and to fund as the cleanup advances.

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.

The Restorical Proven Process

Task 1 — Research and Analysis
Restorical searches for viable historical insurance policies, researches the site history, analyzes the contamination impacts, and underwrites potential coverage — including a proprietary trigger analysis. At the end of Task 1, we provide a clear yes or no on whether a successful cost recovery is possible, along with a strategy and recommendation specific to your situation, even if you are not the policyholder.
Task 2 — Coverage and Funding
When Task 1 confirms viable coverage, Restorical works with your legal counsel to tender the claim, negotiate and secure insurance coverage. Restorical will manage the ongoing claim process, including accounting to ensure the insurance companies are funding your remediation in a timely manner.
