Preliminary Site-Specific Analysis

This property has a documented history as a landfill going back to 1962. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

The Hansville Landfill operated as a municipal solid waste disposal site from 1962 through 1989, accepting solid waste, demolition waste, and septage across three distinct disposal areas. Cleanup under the Standard Cleanup program has included full landfill closure with HDPE-lined cover systems, surface water management infrastructure, and both passive and active landfill gas extraction and flaring systems, along with vapor extraction wells targeting VOCs in soil and groundwater. Construction of the remedy is complete and performance monitoring is ongoing, with future remedial action costs still to be determined. 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.

Contamination at this site — volatile organic compounds, landfill gas, and leachate — is the direct product of nearly three decades of municipal waste disposal that began in 1962, more than two decades before occurrence-based CGL policies ceased covering pollution claims. The remediation expenditures already incurred for landfill closure, engineered cover systems, gas extraction, vapor treatment, and long-term monitoring represent substantial costs tied to operations well within the pre-1986 policy window. With performance monitoring ongoing and future remedial costs yet to be determined, historical carriers who issued CGL policies during the landfill's operating years may be obligated both to recover past cleanup expenditures and to fund the work that remains.

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.
