Bulk Plant cleanup site — Restorical Research
SeaTac Northwest Fuel Farm
Seatac, King County
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.

The SeaTac Northwest Fuel Farm is a fuel storage facility at Seattle-Tacoma International Airport, an airport operational since 1949. Northwest Airlines operated as a major carrier at SeaTac for decades, and the fuel farm — permanent infrastructure tied to those carrier operations — was listed as a contaminated site by Washington Ecology in December 1990. Contamination identified in groundwater and surface water includes halogenated organics, metals (priority pollutants), PCBs, petroleum products, and non-halogenated solvents, with petroleum products also detected in air. The site is classified under the Standard Cleanup program and is currently awaiting cleanup. 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 fuel farm's connection to SeaTac Airport — operational since 1949 — and Northwest Airlines' decades-long presence at the airport place this facility's operations well within the pre-1986 occurrence-based CGL policy era. The breadth of contamination across multiple media — halogenated organics, PCBs, metals, petroleum, and solvents in groundwater and surface water — points to long-term industrial releases from those historical operations. As the site now faces investigation and remediation costs under Washington's Standard Cleanup program, CGL policies issued to the facility's operators during that pre-1986 window may be obligated to fund the cleanup 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.
