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.

This property is a former sand and gravel pit that began accepting residential, commercial, and demolition waste in the 1950s, with burning of waste reported during early operations. Phased closure of the landfill was completed between 1986 and 1990, and the site has been subject to ongoing groundwater and landfill gas monitoring since 1986, along with a soil vapor extraction system operating continuously since 2017. Additional site maintenance — including fence and road repairs, well stability work, and bioberm upkeep — continues under financial assurance. 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.

Landfill operations at this site began in the 1950s, more than three decades before 1986, when occurrence-based Commercial General Liability policies were standard and carried no effective pollution exclusion in Washington. The contamination requiring ongoing monitoring and extraction stems directly from those decades of waste disposal under pre-1986 operations. The remediation costs this property still faces — continued operation of the SVE system, long-term groundwater and landfill gas monitoring, and sustained site maintenance — could plausibly be financed by historical carriers whose policies were in effect when the contamination originated.

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.
