Gas Station cleanup site — Restorical Research
St John Chevron Service Station
St John, Whitman County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1950. 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 Chevron retail service station from the 1950s through the 1970s, with an underground storage tank removed during that decade; the site's retail history extends back to the 1920s. A Phase II environmental site assessment identified petroleum contamination — gasoline-range organics, diesel-range organics, benzene, and xylenes — concentrated in the footprint of the former service station. A $500,000 EPA Brownfields Grant was awarded to the Port of Whitman County for general assessment and future redevelopment planning across multiple properties in the area, with this site among those being evaluated. Cleanup is ongoing under the Voluntary Cleanup Program. 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.

The petroleum contamination at this property traces directly to a Chevron service station and its underground storage tank that operated for two or more decades before 1986, when occurrence-based Commercial General Liability policies were still the industry standard and carried no effective pollution exclusion. Investigation-derived waste management, active remediation, and multi-property Brownfields assessment work all represent ongoing expenditures tied to a release that began during that pre-1986 operational window. Carriers who issued CGL policies to the station's operators during those years may bear a continuing obligation to fund the investigation and cleanup costs now being incurred at this site.

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.
