Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility going back to 1911. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

Terminal 25 South is part of the Harbor Island Superfund Site, a major industrial complex created in 1911 at the confluence of Seattle's waterways, with documented operations spanning secondary lead smelting, shipbuilding, metals fabrication and plating, petroleum product transfer and storage, and port and rail transport. The site was placed on EPA's National Priorities List on September 8, 1983, reflecting contamination traceable to industrial operations that predated 1986. A removal action has been completed — approximately 200,000 cubic yards of contaminated sediments were removed — and future work includes additional general response actions, off-site waste shipments, land and groundwater use restrictions, and ongoing Post-Removal Site Control activities. 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 contamination at Terminal 25 South originated from industrial operations that were already decades old when the site was listed on the NPL in 1983, meaning the pollution events that generated liability occurred well before 1986, when occurrence-based CGL policies still governed. The principal liability that historical carriers may be obligated to fund lies ahead: the general response actions, off-site waste disposal, institutional controls, and Post-Removal Site Control costs that have not yet been incurred. Pre-1986 CGL policies issued to operators during that industrial window carried no effective pollution exclusion in Washington, and those policies may be the mechanism for financing the remediation work still 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.
