Bulk Plant cleanup site — Restorical Research
MC Terminals
40 S Spokane St, Seattle, 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.

MC Terminals operated as a petroleum bulk storage and distribution terminal at 40 South Spokane Street in Seattle's industrial waterfront district near the Duwamish. The site has been listed on Ecology's Confirmed and Suspected Contaminated Sites List since 1991, with confirmed halogenated organics and suspected polycyclic aromatic hydrocarbons (PAHs) and base/neutral/acid organics identified in groundwater. A Site Hazard Assessment initiated in 2014 could not be completed due to insufficient site information, and no active remediation has commenced — the property remains in Awaiting Cleanup status. 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 three contaminant classes found in groundwater at MC Terminals — halogenated organics, PAHs, and BNA organics — are characteristic of long-duration petroleum terminal operations, and the site's 1991 CSCSL listing confirms the contamination was recognized well before modern pollution exclusions became standard. With no remediation yet undertaken and the full scope of cleanup costs still ahead, historical carriers who covered this terminal during its pre-1986 operating years face potential exposure to the investigation, remediation, and long-term monitoring expenses that the property owner will now incur.

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.
