Gas Station cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1960. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property was originally constructed as a gas station in 1960 and operated as such until approximately 1985, after which it was used by several operators for automotive repair through 1991. Cleanup activities under the Standard Cleanup program ran from 1991 to at least 1999, including multiple phases of underground storage tank removal and contaminated soil excavation totaling at least 770 cubic yards and 124 tons. Groundwater remediation involved a pump-and-treat system, a vapor extraction system temporarily converted to air sparging with ORC socks, and off-site treatment of excavated groundwater. Cleanup work 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.

Gasoline contamination at this site originated from underground storage tanks installed and operated from 1960 through 1985 — the full duration of the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. Nearly a decade of documented remediation expenditures — tank removals, large-scale soil excavation, pump-and-treat operations, vapor extraction, and air sparging — were incurred to address releases tied directly to those pre-1986 fueling operations. Historical carriers who issued CGL policies during that twenty-five-year operational window may be obligated both to recover past cleanup costs and to fund the remediation that remains 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.
