Landfill cleanup site — 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 — and recover costs already spent.

This unimproved Lewis County property was used for an undetermined period as an illegal solid waste dump site, with building demolition debris and household waste deposited across multiple disposal areas throughout the property; a USGS topographic map dated 1985 confirms that a "Solid Waste Disposal Area" was present and active on the property by that year. The land was also used for the widespread discharge of firearms. Cleanup activities were initiated under a Voluntary Cleanup Program Agreement, with an Environmental Site Remediation Work Plan drafted to outline further remedial actions, but the project was terminated after at least two years due to insufficient funds and the absence of active cleanup. 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.

Waste disposal at this property was confirmed active by 1985, placing the contaminating events within the period when occurrence-based Commercial General Liability policies carried no effective pollution exclusion. The remediation effort here did not fail for lack of a legal or technical basis — it stalled for lack of funding. Historical carriers whose CGL policies were in effect during the pre-1986 disposal window may be obligated to fund the cleanup costs that the VCP project could not sustain, making policy recovery the most viable path to restarting remediation.

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.
