Gas Station cleanup site — Restorical Research
Sultan Texaco
Sultan, Snohomish County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1919. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

Various gasoline stations have operated at this Sultan, Snohomish County location since the late 1910s, and the property currently operates as a Texaco gasoline station with a fuel dispenser island and convenience store. Four former underground storage tanks totaling 16,000 gallons were removed, and petroleum-contaminated soil stockpiles were disposed of as part of cleanup under the Voluntary Cleanup Program. Proposed groundwater remediation includes injection of Oxygen Release Compound (ORC-A) for in-situ bioremediation, with quarterly and confirmation groundwater monitoring planned as a multi-year effort. 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 property is attributed to historical releases from former underground storage tank systems that were installed and operated decades before 1986 — gasoline station use here dates to the late 1910s, with specific operations documented from 1945 through 1970. Occurrence-based CGL policies issued to the station operators during that pre-1986 window carried no effective pollution exclusion under Washington law. The documented remediation costs already incurred — tank removals, soil disposal, site characterization — and the costs still ahead for groundwater bioremediation and long-term monitoring represent expenditures that historical carriers 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.
