Landfill cleanup site — Restorical Research
SIRTI
Spokane, Spokane County
Restorical Research
Preliminary Site-Specific Analysis

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

The SIRTI property in Spokane was operated as a landfill, receiving buried ash fill containing elevated concentrations of lead, cadmium, and mercury — with contaminated fill material extending to approximately 35 feet in depth across more than 100,000 cubic yards of the site. The landfill had no liner or leachate collection system. Documented remediation activities between 1992 and 1994 included capping contaminated ash fill with a geomembrane and clean soil cover and relocating approximately 24,000 cubic yards of contaminated soil to the Milwaukee Trench. The site remains in Awaiting Cleanup status under Washington State's Standard Cleanup program. 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.

Ash fill disposal generating lead, cadmium, and mercury contamination at this scale is characteristic of industrial waste practices that predate 1986 by decades, when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion. Historical CGL policies issued to operators or property owners during that disposal era remain potentially enforceable against those carriers today. The documented costs of geomembrane capping and mass soil relocation — and the cleanup work still ahead — represent expenditures that historical insurers whose policies were in force during the disposal period may be obligated to fund.

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.
