Gas Station cleanup site — Restorical Research
Sea Gear
Seattle, King County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1975. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

The Sea Gear facility was developed in 1948, with underground storage tanks for gasoline and diesel installed in 1975 to support on-site vehicle fueling operations. Cleanup activities included the removal of those USTs and above-ground storage tanks, along with the decommissioning and closure-in-place of a 500-gallon heating oil underground storage tank. A Voluntary Cleanup Program project was initiated to address contamination but was later terminated due to inactivity, leaving cleanup obligations at this site unresolved. 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 gasoline and diesel underground storage tanks at Sea Gear were installed in 1975 and operated for years under the occurrence-based CGL policies that were standard before 1986 — policies that carried no effective pollution exclusion for petroleum releases of this kind. Historical carriers who issued those policies may be obligated both to reimburse the documented remediation costs already incurred through the Voluntary Cleanup Program and to fund the cleanup work that still lies ahead. With the VCP project terminated and site remediation unresolved, the need to access historical insurance is prospective as much as retrospective.

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.
