Industrial & Manufacturing cleanup site — Restorical Research
Van Dyke Heavy Hauling

Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1955. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property has operated as a trucking facility since 1955, providing heavy hauling, truck storage, and vehicle maintenance and repair, including fueling operations and used oil management. Cleanup activities have included removal of multiple underground and above-ground storage tanks, in-place closure and cleaning of two additional USTs, removal of 31 gallons of spilled material and contaminated soil, cleaning of storm drains and catch basins, and removal of drums. The site is enrolled in the Voluntary Cleanup Program, and ongoing quarterly groundwater monitoring has been recommended as cleanup continues. 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.

Fueling operations and petroleum storage at this property began in 1955 — more than three decades before the 1986 threshold at which occurrence-based Commercial General Liability policies effectively ceased covering pollution releases. The TPH-G and benzene contamination linked to the former USTs and fueling activities here is precisely the kind of long-running industrial release those pre-1986 CGL policies were designed to address. With quarterly groundwater monitoring still recommended and remediation ongoing, the historical carriers who issued policies during Van Dyke's decades of pre-1986 operations may be obligated both to recover past cleanup costs and to fund the work that remains.

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.
