Bulk Plant cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property is the former site of the Cornwall Fuel Company bulk fuel facility, which ceased operations in 1960 and is identified as the source of an ongoing petroleum hydrocarbon plume beneath the property. Cleanup activities were conducted during construction of the current structure in 2005–2006, and institutional controls are currently in place. Groundwater and organic vapor monitoring has been ongoing since 2001 and is planned to continue on a biennial basis. 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 here originates from bulk fuel storage and distribution operations that ended in 1960 — more than two decades before 1986, when occurrence-based Commercial General Liability policies began including effective pollution exclusions. Site documents describe the residual hydrocarbons as highly weathered after more than fifty years, confirming that the contamination event is tied directly to that pre-1986 operational window. The documented remediation expenditures — construction-phase cleanup, institutional controls, and decades of groundwater and vapor monitoring — represent costs that historical carriers whose policies were in force during the Cornwall Fuel Company's operating years 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.
