Gas Station cleanup site — Restorical Research
Usk General Store
Usk, Pend Oreille County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1970. 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 general store since 1965 and expanded to include a gas station with underground storage tanks in 1970. A leak from one of the original USTs was identified in 1986, prompting tank removals and contaminated soil excavation. Subsequent cleanup under the Voluntary Cleanup Program has included in-situ chemical oxidation using Fenton's reagent in 2013 and 2014, with quarterly groundwater monitoring ongoing since 2010. The property remains in active commercial use as a gas station, general store, and restaurant, with multiple pump islands serving both commercial trucks and passenger vehicles. 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 traces directly to underground storage tanks installed in 1970 — sixteen years before occurrence-based CGL policies gave way to claims-made forms with absolute pollution exclusions. The documented remediation expenditures spanning more than a decade — tank removals, soil excavation, chemical oxidation, and long-term groundwater monitoring — arose from releases tied to those pre-1986 operations. With cleanup still underway, historical carriers who issued CGL policies during the 1970-through-1986 operational window may be obligated both to recover past remediation costs and to fund the remaining cleanup work.

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.
