Auto Body cleanup site — Restorical Research
Petersen Brothers Inc
Sumner, Pierce County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a auto body / repair shop going back to 1970. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property has served as an equipment storage and maintenance facility for Petersen Brothers Inc since the early 1970s, with a maintenance shop building featuring service bays used for truck repair and vehicle servicing. In 1999, four underground storage tanks were excavated and removed along with approximately 400 cubic yards of contaminated soil, and 40,000 gallons of groundwater were treated using granular activated carbon. Cleanup is ongoing under the Voluntary Cleanup Program, with Ecology requiring continued soil and groundwater sampling, a terrestrial ecological evaluation, and potential vapor intrusion studies as of 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.

Contamination at this facility traces to underground storage tanks and waste-oil conveyance systems installed and operated from the early 1970s through at least 1985 — infrastructure that was in active use for more than a decade before occurrence-based CGL policies gave way to claims-made forms with pollution exclusions. The documented remediation costs already incurred — tank removals, large-scale soil excavation, groundwater treatment — and the additional investigation and cleanup work Ecology still requires represent expenditures that historical carriers who covered the facility during its pre-1986 operational window may be obligated both to reimburse 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.
