Industrial & Manufacturing cleanup site — Restorical Research

Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1964. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property operated as the Northwest Construction Company, an industrial facility with six underground storage tanks holding gasoline, diesel, lubricating oil, and waste oils, along with service bays and sand blasting operations. Cleanup under the Voluntary Cleanup Program has spanned from 1989 through at least 2008, including removal of all six USTs and associated piping, excavation of 510 cubic yards of petroleum-contaminated soil, free product recovery and groundwater treatment, and disposal of sand blast grit classified as dangerous waste. Multiple monitoring wells were installed and eventually abandoned over the course of the project. Cleanup work is ongoing. 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 six underground storage tanks removed from this site in 1989 were already below industry standards and lacked cathodic protection — consistent with installation around 1964, more than two decades before occurrence-based CGL policies gave way to claims-made forms with pollution exclusions. The petroleum contamination in soil and groundwater originated from tank leaks and historical spills tied directly to those pre-1986 industrial operations. Nearly two decades of documented remediation expenditures — tank removals, soil excavation, groundwater recovery, hazardous waste disposal, and long-term monitoring — represent costs that historical carriers who covered this facility during its pre-1986 operating 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.
