Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1955. 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 Shell gasoline station from 1955 to 1982, with six underground storage tanks ranging from 500 to 10,000 gallons storing leaded gasoline, unleaded gasoline, and waste oil. Budget Rent A Car purchased the operation in 1983, and the USTs were removed between 1983 and 2003. Cleanup under the Voluntary Cleanup Program has included excavation of over 10,000 tons of gasoline-affected soil, operation of a pump-and-treat groundwater containment system from 2003 to 2008, and deployment of soil vapor extraction and air sparging systems, with ongoing groundwater monitoring and natural attenuation continuing through the project. 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 property originated from underground storage tanks installed and operated during a Shell station era that began in 1955 — more than three decades before occurrence-based CGL policies were displaced by claims-made forms with pollution exclusions. Documented remediation expenditures already total an estimated $1,669,300, covering soil excavation, pump-and-treat operations, vapor extraction, and long-term monitoring — costs tied directly to releases from those pre-1986 fueling operations. Historical carriers who issued CGL policies to the Shell or Budget operators during the 1955–1983 window may still be obligated both to recover past cleanup costs and to fund the monitoring 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.
