Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1959. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property was constructed as a Richfield Gas Station in 1958–1959 and operated continuously as an automotive-repair facility and gasoline-fueling station through 1988, with gasoline sales spanning from 1959 to at least 1988 under successive fuel brands. Four underground storage tanks totaling 12,280 gallons were closed in place in 1988 and later excavated and removed in 2007 along with associated piping and 100 cubic yards of petroleum-contaminated soil, which was disposed of off-site in 2015. The site is enrolled in the Voluntary Cleanup Program, with vapor-extraction systems under consideration as a next remediation phase. 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.

Gasoline contamination at this property originated from underground storage tanks installed in 1958 and operated for three decades — entirely within the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. The documented remediation costs already incurred — tank removal, soil excavation, off-site disposal, and ongoing VCP oversight — along with the vapor-extraction work still being evaluated, represent expenditures that historical carriers who issued CGL policies to the station's operators during that pre-1986 window may be obligated both to reimburse 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. 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.
