Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1965. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property operated as Unocal Service Station Number 5028, with facility development documented as early as 1965 and underground gasoline, diesel fuel, and used oil storage tanks serving the pump island. Contamination was discovered in May 1986 when corroded steel tanks — showing holes from long-term deterioration — were removed and 2,000 gallons of contaminated water and free product were pumped from the excavation. Further cleanup in 1990 included additional tank removals and excavation of approximately 50 cubic yards of contaminated soil. The site entered the Voluntary Cleanup Program, which was terminated in 2015 due to inactivity. 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.

Petroleum contamination at this site originated from underground storage tanks that were in the ground well before 1986, with facility records dating to 1965 and the tanks themselves showing extensive corrosion consistent with decades of service. Occurrence-based CGL policies issued to the station's operators during that pre-1986 window carried no effective pollution exclusion under Washington law. The documented remediation expenditures — tank removals, soil excavation, free-product recovery, and years of program oversight — represent costs that historical carriers may be obligated to reimburse, and with the Voluntary Cleanup Program terminated without completion, further cleanup obligations may yet arise.

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.
