Bulk Plant cleanup site — Restorical Research
Transmart Petroleum Avon Bulk Plant
Mount Vernon, Skagit County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal going back to 1924. 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 bulk petroleum storage and distribution facility since 1924, loading trucks for delivery of gasoline, diesel fuel, and heating oil. Twelve underground storage tanks were installed in 1971 and 1975, and petroleum contamination from those tanks prompted their excavation and removal in 1999. Additional remediation has included spill-bucket upgrades, asphalt containment berms, and emergency shutoff valves on drain pipes, with groundwater monitoring documented from at least 1997 through 2018. Cleanup work is ongoing under the Standard 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.

Petroleum contamination at this facility traces to underground storage tanks installed in 1971 and 1975 — infrastructure that served a bulk distribution operation continuously active since 1924. Any CGL policies issued to the operators of this plant during that half-century of pre-1986 fueling operations would have been occurrence-based, with no effective pollution exclusion under Washington law. The documented remediation costs here — tank removal, containment upgrades, and over two decades of groundwater monitoring — represent expenditures the historical carriers may be obligated both to recover and to fund as cleanup continues.

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.
