Bulk Plant cleanup site — Restorical Research
BNSF Railway Black Tank Property
3202 E Wellesley, Spokane, Spokane County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a bulk fuel distribution terminal going back to 1910. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property served as a bulk petroleum storage facility from possibly as early as 1910 until the final removal of its 50-foot diameter aboveground storage tank — the Black Tank — in 2006, with associated piping and pumping infrastructure supporting petroleum distribution throughout that period. One or more releases of petroleum products to the environment occurred during operations. Remediation has included excavation and removal of the Black Tank and contaminated soil, completion of a Remedial Investigation/Feasibility Study, and plans to install and operate bioventing and biosparging systems, with steam enhanced extraction identified as a contingent technology. The project involves ongoing monitoring, operation and maintenance, and future financial assurance requirements. 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.

Petroleum contamination at this property traces to bulk storage operations that began as early as 1910 — nearly eight decades before the 1986 threshold after which occurrence-based CGL policies began incorporating effective pollution exclusions. The Black Tank and its associated infrastructure were in active petroleum service for most of the twentieth century, a period during which historical carriers issued policies with no meaningful bar to pollution claims arising from gradual releases. The documented remediation expenditures — tank and soil excavation, site investigation, and the planned bioventing and biosparging program — represent costs that historical carriers may be obligated both to recover and to fund as the project advances through its remaining phases.

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.
