Bulk Plant cleanup site — Restorical Research
Cadman Premix
Bellevue, King County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

This property served as a bulk fuel storage and handling site for Cadman's concrete products batching operations, with two diesel underground storage tanks and an above-ground storage tank shed on site. The USTs were removed by Lakeside Industries in 1988, and historical petroleum releases from those tanks and the AST shed left diesel-range TPH contamination in soil and groundwater. In June 1998, Cadman completed a partial remediation — excavating and removing 323 tons of TPH-affected soil and the AST shed, and initiating quarterly groundwater monitoring through at least Fall 1999. The site remains in Standard Cleanup status with full remediation still pending. 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 diesel contamination documented here traces to underground storage tanks that were in active service before 1986, when occurrence-based Commercial General Liability policies routinely covered pollution-related claims without effective exclusion. The full cleanup of residual TPH in soil and groundwater still lies ahead, and the costs that entails — investigation design, active remediation, and long-term monitoring — are precisely the type of forward exposure those pre-1986 policies were structured to fund. Property owners facing that pending cleanup obligation may find that historical carriers whose policies were in force during the pre-1986 operational window remain obligated to cover the costs to come.

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.
