Gas Station cleanup site — Restorical Research
SR 195 Widening Project
Colfax, Whitman County
Restorical Research
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 a gasoline service station beginning in the mid-1960s, with two underground storage tanks — one 10,000-gallon and one 8,000-gallon — dispensing gasoline until the station was abandoned in the late 1970s. The USTs were discovered and removed during a road-widening project in 1998, along with 44 cubic yards of petroleum-contaminated soil. Subsequent soil and groundwater sampling in 2013 and 2014 confirmed residual contamination, and remediation efforts remain ongoing. The property is currently occupied by a Farmers Insurance office. 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 installed and operated in the mid-1960s through the late 1970s — squarely within the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. Documented remediation costs spanning from the 1998 tank removal through more than a decade of follow-up investigation and monitoring represent expenditures that historical carriers may be obligated both to reimburse and to fund as cleanup continues. The long gap between tank abandonment and discovery underscores exactly the kind of gradual, unforeseen release these pre-1986 policies were designed to cover.

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.
