Preliminary Site-Specific Analysis

This property has a documented history as a auto body / repair shop going back to 1973. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property was developed in 1973 with the construction of a repair shop and office buildings, and was used for parking and repair of trucks, cranes, and other construction equipment, along with a paint shop, truck wash pad, and on-site chemical storage. Two 500-gallon underground storage tanks and an above-ground storage tank for used oil were present on the southeastern portion of the site. Cleanup under the Voluntary Cleanup Program has included removal of both USTs and 250 tons of contaminated soil in 1995, followed by a 2007 remedial excavation removing 14 tons of dangerous waste and 208 tons of non-hazardous waste. Further work remains under active evaluation, including soil vapor extraction, in-situ chemical oxidation, new monitoring wells, and quarterly groundwater monitoring through 2024–2025. 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.

Truck repair, paint shop operations, and chemical storage at this property began in 1973 — more than a decade before occurrence-based CGL policies began reliably excluding pollution claims. The petroleum hydrocarbon and chlorinated solvent contamination attributed to those historical operations and fill materials is precisely the type of slow, diffuse release that pre-1986 policies were written to address. Two separate excavation phases have already produced documented remediation costs, and prospective expenditures for vapor extraction, chemical oxidation, and extended groundwater monitoring remain on the table — all of which may be recoverable from historical carriers whose policies were in force during those years of operation.

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.
