Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1964. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

This property was developed as a service station in 1964, replacing a prior residential use dating to 1936. The original underground storage tanks — gas and diesel — were decommissioned or replaced in 1989 after a release was discovered in 1988. Cleanup under the Voluntary Cleanup Program has included UST removal, excavation of over 1,100 cubic yards of petroleum-impacted soil, treatment of three million gallons of groundwater through an extraction system, application of an Oxygen Release Compound, and multi-year groundwater monitoring from at least 1993 through 2015. The site continues to operate as a Shell-branded wholesale fuel retail facility. 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.

Petroleum contamination at this property originated from underground storage tanks installed and operated beginning in 1964 — more than two decades before occurrence-based CGL policies gave way to claims-made forms with absolute pollution exclusions. The documented remediation expenditures here — tank removal, large-scale soil excavation, a multi-million-gallon groundwater extraction campaign, and over twenty years of monitoring — represent costs tied directly to releases from those pre-1986 operations. Historical carriers who issued CGL policies during the 1964–1986 operational window may be obligated both to recover past cleanup costs and to fund remediation still ahead.

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.
