Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal going back to 1920. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property operated as the Unocal Edmonds Bulk Fuel Terminal from the early 1920s through June 1992, serving as a petroleum bulk storage and distribution facility for over seven decades. Cleanup activities under a Standard Cleanup have included the excavation and removal of five underground storage tanks, operation of a free petroleum product recovery system that has recovered 9,500 gallons of product, and the abandonment of 16 monitoring wells and 4 sumps. The remediation is a multi-year effort spanning at least 30 months, with Unocal responsible for all associated remedial action costs. 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 terminal originated from bulk fuel storage and distribution operations that began more than six decades before 1986, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion. The documented remediation expenditures — tank removals, thousands of gallons of free product recovery, well abandonment, and an ongoing multi-year cleanup — are tied directly to releases during those pre-1986 terminal operations. Historical carriers who issued CGL policies during that extensive operational window may be obligated both to recover costs already incurred and to fund the cleanup work that continues ahead.

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.
