Gas Station cleanup site — Restorical Research
Dels Triangle Texaco
Wenatchee, Chelan County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1956. 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 Texaco gasoline station from 1956 to 1982, then continued as a gasoline station under subsequent ownership until 1998. Six underground storage tanks were removed in 2002, along with approximately 25 cubic yards of contaminated soil and 96 gallons of liquid and sludge from the tanks. The site was placed on Ecology's contaminated sites list in 2003 and underwent a Site Hazard Assessment in 2006; cleanup work remains ongoing, and the property has since been used for vehicle repairs and sales. 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 installed and operated beginning in 1956 — three decades before occurrence-based CGL policies gave way to claims-made forms with pollution exclusions. The documented remediation expenditures — tank removal, soil excavation, hazard assessment, and continued regulatory oversight — trace directly to releases from those pre-1986 fueling operations. Historical carriers who issued CGL policies during the 1956–1982 Texaco era and the subsequent operating period may be obligated both to recover past cleanup costs and to fund the remediation still 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.
