Heating Oil Tank cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as a property with a heating oil tank predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This industrial office-warehouse property in Oak Harbor contained an approximately 300-gallon heating oil underground storage tank that was removed in June 2004 after documented leakage from rust and perforations. Remediation included pumping roughly 220 gallons of accumulated oil and water from the tank, followed in August 2004 by excavation and off-site thermal treatment of approximately 62 tons of diesel-impacted soil, and placement of 90 pounds of oxygen release compound to promote natural attenuation. The site was enrolled in Washington's Voluntary Cleanup Program in October 2004 but was removed for inactivity in November 2006, leaving remediation incomplete. 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 heating oil tank at this property was installed and in service well before 1986 — the building itself predates 1980 based on the presence of asbestos-containing materials — placing the contamination's origin squarely within the era of occurrence-based Commercial General Liability policies that carried no effective pollution exclusion. The documented remediation costs incurred in 2004 — tank removal, contaminated soil excavation, thermal treatment, and attenuation enhancement — represent expenditures that historical carriers may be obligated to recover. Because the site remains in 'Cleanup Started' status with no closure determination, future investigation and remediation work almost certainly lies ahead, and those forthcoming costs may be equally claimable against the policies in force when the tank was leaking.

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.
