Snipes Mountain Landfill

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.

Snipes Mountain Landfill accepted municipal solid waste and septage — the latter disposed into unlined ponds on the property — until the landfill closed on March 30, 1994. Remediation has included the pumping out and closure of those unlined septage ponds in 1991 and the installation of a final landfill cover in 1994. Groundwater contamination, including PCE detections dating to at least 1989, has been under ongoing investigation and monitoring pursuant to an Agreed Order. Cleanup work at the site remains active. 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 landfill and septage disposal operations that generated the contamination here were in place well before 1986, when occurrence-based Commercial General Liability policies were standard and carried no effective pollution exclusion. PCE groundwater contamination traced to historical septage disposal represents precisely the type of slow, continuous release those policies were written to address. The documented remediation costs — pond closures, capping, and years of groundwater monitoring and investigation under an Agreed Order — are expenditures for which historical carriers whose policies were in effect during the operational window may be obligated both to recover and to fund going forward.

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.
