Preliminary Site-Specific Analysis

This property has a documented history as a landfill going back to 1960. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

Dryden Landfill has been owned and operated by Chelan County since 1960, accepting municipal and agricultural solid waste until closure activities began in 1986. Initial closure in 1986 included placement of a substandard cover over the landfill and installation of four groundwater monitoring wells; a compliant final cover was not installed until 2004. The site now operates under a Restrictive Covenant, with Chelan County responsible for ongoing post-closure monitoring of groundwater, surface water, landfill gas, and ground settling. 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 property ran from 1960 through 1987 — a span that encompasses the entire era when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion. The leachate migration and landfill gas generation that have driven decades of regulatory oversight are attributable directly to waste deposited during those pre-1986 years. Historical carriers who issued CGL policies to Chelan County during the landfill's operational window may still be obligated to address the remediation costs the County has incurred and continues to bear under its post-closure O&M mandate.

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.
