Gas Station cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1940. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

This property has operated as a retail gasoline station since at least 1940 and is currently branded as an Exxon station with three underground storage tanks and a four-dispenser pump island. Petroleum contamination was identified in the mid-1990s, linked to a faulty spill containment system from a 1993 tank upgrade, and the site entered the Voluntary Cleanup Program. Remediation has included excavation and disposal of 5 tons of petroleum-impacted soil, recovery of liquid phase hydrocarbons, abandonment of a monitoring well, and quarterly groundwater monitoring conducted from 1996 and resumed in 2016–2017. 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 operations at this site date to at least 1940 — more than four decades before 1986, when occurrence-based Commercial General Liability policies still carried no effective pollution exclusion in Washington. Underground storage tanks installed in 1976 and 1984 stored and dispensed leaded and unleaded gasoline during a period when CGL coverage was routinely issued to fuel retailers. The documented remediation expenditures — soil excavation, hydrocarbon recovery, and decades of groundwater monitoring — represent costs that historical carriers who wrote policies during that operational window may be obligated both to reimburse and to 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.
