Gas Station cleanup site — Restorical Research
Museum of Flight Property
Seattle, King County

Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1925. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

This property was originally developed as a gasoline service station in 1925, with several successive generations of service stations operating at the site until the early 1980s. Two underground storage tanks associated with the former service station were removed during excavation in 1985–1987, and leaking UST contamination was identified in 2001. No active remediation work has commenced; the site remains in the awaiting-cleanup phase under Washington's Standard Cleanup program. 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 underground storage tanks that produced contamination here were installed and operated across more than five decades of pre-1986 service station activity, a period when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. Leaking UST contamination of the kind identified at this property in 2001 — originating from operations stretching back to 1925 — is precisely the slow, historical release those policies were written to address. The investigation, remedial design, and active cleanup that still lie ahead for this property are expenditures that historical carriers whose policies were in force during the pre-1986 operational window may be obligated to fund.

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.
