Landfill cleanup site — Restorical Research
Brett Pit
Coulee Dam, Okanogan County
Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a landfill going back to 1941. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

Brett Pit served as the primary waste disposal site for the Grand Coulee Dam facility from approximately 1941 to 1978, receiving facility waste, hazardous waste, and, for a period, the City of Coulee Dam's municipal solid waste. Disposed materials included PCB-contaminated transformer oils and lead-acid batteries. Site investigation activities have included excavation of decontamination pits and steam cleaning of drilling equipment; the Bureau of Reclamation has also undertaken the retrofilling or phase-out of 20 PCB-contaminated electrical transformers, with removed oils sent for incineration. No comprehensive cleanup of the pit itself has yet commenced. 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 Brett Pit spanned nearly four decades beginning in 1941, with PCB-laden transformer oils and hazardous materials entering the ground long before 1986 — the year pollution exclusions became standard in Commercial General Liability policies. The pre-1986 occurrence-based CGL policies issued to operators and contractors associated with the Grand Coulee Dam facility during those decades carried no effective pollution exclusion under Washington law. Investigation and remediation costs now facing the responsible parties — transformer retrofilling, oil incineration, and the pending comprehensive cleanup of the pit — represent expenditures that historical carriers 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.
