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.

This property operated as a gasoline service station from the 1940s until 1973, when the station buildings caught fire and burned down. Two 500-gallon underground storage tanks associated with those historical operations were discovered with structural failures during a utility relocate, triggering a Standard Cleanup. Remediation has included excavation and removal of both USTs, disposal of approximately 3,000 tons of petroleum-impacted soil, pumping and disposal of 10,000 gallons of impacted groundwater and sludge, and excavation and disposal of 157 tons of asbestos-containing materials. Additional soil remediation and groundwater monitoring well installation have been recommended, and the project remains 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.

The petroleum contamination at this property traces to underground storage tanks installed and operated during a gasoline station that functioned for decades before 1986 — the year occurrence-based Commercial General Liability policies ceased to be the industry standard and began including effective pollution exclusions. Structural failure of those aged tanks, not a discrete accident, is the identified release mechanism, which is precisely the type of slow, long-tail contamination that pre-1986 CGL policies were written to cover. The documented remediation costs here — UST excavation, large-scale soil disposal, groundwater treatment, and asbestos abatement — are tied directly to those historical operations, and historical carriers who issued CGL policies during the station's operating years may be obligated both to recover those expenditures and to fund the cleanup work 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.
