Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a auto body / repair shop going back to 1958. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property operated as an auto wrecking yard from at least 1958, with operations centered on automobile wrecking and parts salvaging, auto body storage, and engine and transmission dismantling. Petroleum releases attributable to those historical operations contaminated soil and groundwater across the site. Cleanup under the Voluntary Cleanup Program has included significant soil and tank excavation amounting to thousands of tons and hundreds of cubic yards, removal of thousands of gallons of affected groundwater, demolition of structures, asphalt removal, and in-situ treatment using Oxygen Release Compound. Ongoing groundwater monitoring continues, and further excavation is planned in connection with property redevelopment. 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 petroleum contamination documented at this site originated from auto wrecking and dismantling operations that were active for decades before 1986, when occurrence-based Commercial General Liability policies still lacked effective pollution exclusions. Historical CGL carriers who issued policies to the Northwest Auto Wrecking facility during that pre-1986 operational window had no such exclusion and remain potentially obligated for remediation costs. The documented remediation expenditures — soil and tank excavation, groundwater recovery, in-situ bioremediation, and long-term monitoring — represent costs those carriers may be required both to recover for past work 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.
