Public Works cleanup site — Restorical Research
RADAR HILLS SEWER SYSTEM
Othello, Franklin County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility 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 was established in 1951 as a United States Air Force aircraft control and intercept facility, comprising 66 structures including dormitories, housing units, a radar tower, an auto maintenance shop, and a vehicle fueling station. The Air Force closed the facility in 1975, and contamination from leaking underground storage tanks — including gasoline — was identified during initial investigations in 1998. A 2007 site scoring assessment confirmed soil contamination above cleanup levels, and the site is now subject to formal cleanup proceedings 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.

Every fueling and maintenance operation at this Air Force facility — the source of the documented UST contamination — took place between 1951 and 1975, entirely within the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The contamination now confirmed in the soil here was occurring during precisely the period those policies were written to cover. Investigation costs already incurred and the remediation expenditures ahead could plausibly be recovered from historical carriers whose policies were in force during the decades this facility was active.

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.
