Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal going back to 1951. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property served as a Defense Fuel Support Point beginning in 1951, when the Air Force converted it to a bulk jet fuel storage and transfer facility. At its peak the site housed ten aboveground storage tanks, nine underground storage tanks, fuel distribution infrastructure, and PCB-containing transformers — receiving, storing, and distributing bulk jet fuel for military organizations in the region. Cleanup under the Standard Cleanup program has included demolition and removal of all tanks and transformers, free-product recovery of 3,000 gallons of fuel, and air sparging and soil vapor extraction that removed over 1.3 million pounds of hydrocarbons, with active remediation running from 1997 through 2002 and ongoing monitoring and assessment continuing today. 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 releases at this facility trace to fuel storage and distribution operations that ran for decades before 1986, with documented contamination events between 1979 and 1985 alone. Occurrence-based CGL policies issued to the operators during that pre-1986 window carried no effective pollution exclusion under Washington law and remain enforceable. The scale of documented remediation costs — tank and transformer removal, large-volume product recovery, vapor extraction of over 1.3 million pounds of hydrocarbons, and years of monitoring — represents expenditures the historical carriers may be obligated to reimburse, with additional soil remediation still 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.
