Gas Station cleanup site — Restorical Research
Mount Vernon Gasoline Spill
Mount Vernon, Skagit County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a gasoline service station going back to 1960. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

Gasoline contamination at this Mount Vernon property has been tracked since 1988, with the most likely source identified as an adjacent Chevron station that operated from the 1960s through the early 1980s. Petroleum odors were noted as early as the 1970s and gasoline fumes confirmed by 1986. Cleanup activities have included historical tank removals, pumping, steam cleaning, and sealing of a contaminated telephone vault, with the site under ongoing management as a Standard Cleanup project. 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 gasoline contamination here traces to service station operations that began in the 1960s — more than two decades before occurrence-based CGL policies gave way to claims-made forms with pollution exclusions. This is characterized as long-time contamination with no recent accidental release, meaning the releases occurred squarely within the window when historical carriers were issuing occurrence-based policies in Washington. The remediation costs already incurred and the cleanup work still ahead represent expenditures those carriers may be obligated both to recover and to fund going forward.

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.
