Gas Station cleanup site — Restorical Research
Dollar General Retail Store Centralia
Centralia, Lewis County

Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1963. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property operated as an Oil & Gas station and oil warehouse from approximately 1963 to 1983, with three underground storage tanks on site throughout that period. The USTs were removed in 1986; decades later, in May and June 2021, active cleanup addressed the legacy contamination — two areas of petroleum-impacted soil were excavated, removing 1,626 tons at a documented cost of $151,690. A vapor barrier was installed, and natural attenuation of groundwater is anticipated under a planned long-term monitoring 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 Centralia property is directly attributed to underground storage tanks operated from 1963 through the early 1980s — more than two decades of pre-1986 operations during which occurrence-based CGL policies had no effective pollution exclusion. The excavation of 1,626 tons of impacted soil and the installation of a vapor barrier, at a cost exceeding $151,000, document the scale of remediation expenditures tied to those historical operations. Carriers who issued CGL policies to the oil and gas facility during its operating window may still be obligated to fund both the costs already incurred and the long-term monitoring program yet to come.

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.
