Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1940. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

The original building at this site was constructed in 1940 as a gas station at 2955 Westlake N, with multiple underground storage tanks for gasoline and heating fuel and hydraulic service lifts on the property. The station operated through at least 1976; some USTs were removed as late as 1990, indicating the tanks had been in the ground for decades before decommissioning. Petroleum hydrocarbon contamination associated with those historical UST operations has been documented at the site, which is now enrolled in Washington State's Voluntary Cleanup Program with cleanup underway. 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 contamination at this property originates from underground storage tank operations that began in 1940 — more than four decades before 1986, when occurrence-based Commercial General Liability policies were still the industry norm and contained no effective pollution exclusion in Washington. Releases from gasoline and heating-fuel USTs installed at the outset and left in service for decades represent precisely the kind of long-tail environmental liability those pre-1986 policies were underwritten to cover. Historical carriers who issued CGL policies during the station's operational years may bear obligations toward the remediation expenditures now being incurred under the Voluntary Cleanup Program — and toward cleanup costs still to come.

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.
