Preliminary Site-Specific Analysis

This property has a documented history as a landfill going back to 1950. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

The State of Washington has operated hospital facilities at the Eastern State Hospital Pine Lodge location since approximately 1891. Prior to 1970 — likely in the 1950s — buildings on the property were demolished and the debris landfilled on-site, creating an unpermitted landfill containing asbestos, PAHs, dioxins and furans, arsenic, lead, mercury, and VOCs. In August 2023, a wildfire ignited the buried landfill material, creating active contamination pathways to groundwater and air approximately 100 feet from West Medical Lake. Under Agreed Order DE 23299, a remedial investigation is now underway to determine whether the historic landfill has contaminated soil and groundwater; cleanup is in progress. 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 hazardous substances in this landfill — asbestos, heavy metals, PAHs, dioxins — were deposited during demolition operations that took place decades before 1986, when occurrence-based CGL policies were standard and carried no effective pollution exclusion. The 2023 fire exposed and mobilized contaminants that had been buried since the 1950s, but the contamination source is the original landfilling, not the fire itself. Remedial investigation, fire suppression, groundwater assessment, and the cleanup work ahead represent substantial costs that historical carriers who covered the state's operations during that pre-1986 window 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.
