Gas Station cleanup site — Restorical Research
Houghton Village Shopping Plaza

Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1954. 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 approximately 1954 to 1965, with multiple underground storage tanks and a hydraulic hoist in service during that period. Gasoline-range petroleum hydrocarbons and benzene were subsequently detected in groundwater at the site, with Ecology's records citing a leaking underground storage tank as both the source and cause. Documented remediation work includes excavation and removal of 1,500 cubic yards of contaminated soil, removal of multiple USTs, disposal of 33,400 gallons of petroleum-impacted groundwater, well decommissioning, and ongoing groundwater monitoring; the property is also enrolled in the Voluntary 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 at this property were installed and in active use from 1954 through 1965 — more than two decades before the 1986 threshold after which occurrence-based CGL policies began incorporating effective pollution exclusions. Ecology has formally attributed the petroleum hydrocarbon and benzene contamination here to those historical UST operations, establishing a direct regulatory link between the pre-1986 activity and the current remediation obligation. The documented cost trail — large-scale soil excavation, tank removals, tens of thousands of gallons of impacted groundwater recovered, and multi-year monitoring — represents expenditures that historical carriers whose policies were in force during the 1954–1965 operational window may be obligated to both recover and fund going forward.

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.
