Public Works cleanup site — Restorical Research

Restorical Research
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 those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

NAS Whidbey Island was commissioned in 1942, and operations at the facility have generated hazardous wastes since the 1940s. Operable Unit 5 encompasses areas used for construction-debris disposal from the 1940s through the 1970s and firefighting training with waste fuels — including aviation gasoline and JP-5 — from 1967 to 1982. Investigations have confirmed halogenated organics, priority pollutant metals, petroleum products, polycyclic aromatic hydrocarbons, and conventional organic contaminants in groundwater and surface water, and cleanup under the Standard Cleanup program is underway. 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 contamination at OU5 traces to naval operations that began in 1942 and continued through decades of waste disposal and firefighting-training burns well before 1986. Occurrence-based CGL policies in force during that window — when halogenated organics, priority pollutant metals, and petroleum products were being released into groundwater and surface water — carried no effective pollution exclusion. The ongoing remediation costs at this site represent expenditures that historical carriers may be obligated both to recover and to fund going forward.

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.
