Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility going back to 1942. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.

Ault Field was commissioned on September 21, 1942 as a U.S. Navy installation for rearming and refueling patrol planes, with fire training areas operational from the same year. Over decades of military use, the base accumulated multiple contamination sources — AFFF firefighting foam use documented since at least 1964, landfill operations from 1959 through 1970, and aircraft crash sites dating to 1976, 1981, and 1985. Confirmed contamination spans groundwater, surface water, and air, with contaminants including halogenated organics, PFAS, metals priority pollutants, pesticides, and non-halogenated solvents. Cleanup is underway under the Standard Cleanup program. 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.

Military operations at Ault Field began in 1942 — more than four decades before the 1986 shift from occurrence-based to claims-made CGL policies. AFFF use, fire training activities, and landfill operations throughout the 1940s, 1950s, 1960s, and 1970s generated the halogenated organics, PFAS, and metals contamination now confirmed across multiple environmental media. The remediation costs required to address contamination from those pre-1986 operations may be recoverable from historical carriers whose occurrence-based policies were in force during the decades the releases occurred.

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.
