Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1927. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property operated as a Texaco gas station from 1927 through 1988, with five underground storage tanks storing gasoline, diesel, and used oil on-site. Cleanup under the Voluntary Cleanup Program ran from 2000 to 2006 and included removal of all five USTs and 30 cubic yards of petroleum-impacted sludge in 1988, followed by additional soil excavations totaling roughly 110–120 cubic yards in 2000 and 2001 and groundwater monitoring from 2000 to 2002. Cleanup work at the site is ongoing. 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 traces to underground storage tanks that served a gas station for over sixty years, beginning more than five decades before 1986. Occurrence-based Commercial General Liability policies issued to the operators during that long pre-1986 window carried no effective pollution exclusion under Washington law and remain enforceable today. The documented remediation expenditures — tank and sludge removal, repeated soil excavations, groundwater monitoring — represent costs the historical carriers may be obligated both to reimburse and to fund as cleanup 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.

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.
