Public Works cleanup site — Restorical Research
USPS Westwood Station
Seattle, King County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility going back to 1980. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

This property has operated as a United States Postal Service facility since 1980, with a 10,000-gallon underground storage tank fueling the station's vehicle fleet. Cleanup under the Voluntary Cleanup Program has included removal of the UST and excavation of approximately 4,600 cubic yards of contaminated soil in 1991, operation of a groundwater pumping and activated-carbon treatment system from 1991 through 2002, injection of 440 pounds of oxygen release compound in 2004, and ongoing quarterly groundwater monitoring continuing through the present. The post office remains in active operation. 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 site originated from a gasoline UST installed and operated years before 1986, when occurrence-based Commercial General Liability policies carried no effective pollution exclusion in Washington. More than three decades of documented remediation expenditures — tank removal, large-scale soil excavation, eleven years of groundwater pump-and-treat, in-situ chemical injection, and long-term monitoring — represent costs that historical carriers who issued CGL policies during the pre-1986 operational window may be obligated both to reimburse and to fund as cleanup continues.

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.
