Restorical Research
Preliminary Site-Specific Analysis

This property has a documented history as a landfill going back to 1975. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.

The Ostrander Rock Disposal site operated as a solid waste landfill from at least 1975, accepting logs, woodwaste, clarifier waste, carbon ash, demolition debris, plastic poly wastes, and paper products at a facility constructed without a liner. A dike failure occurred in 1977 and leachate leaks were documented in 1980, prompting leachate control efforts including a groundwater cut-off trench. The site is currently subject to ongoing annual methane and groundwater monitoring and has been designated under the Model Toxics Control Act for future cleanup, indicating a multi-year remediation and oversight process ahead. 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 began no later than 1975 — more than a decade before 1986, when occurrence-based Commercial General Liability policies still carried no effective pollution exclusion in Washington. The absence of a liner meant leachate and landfill gas were migrating into surrounding soil and groundwater from the outset, and the manganese contamination and methane now documented are directly traceable to those pre-1986 disposal activities. Historical carriers whose CGL policies were in force during the landfill's operating years may be obligated to fund the multi-year cleanup, long-term monitoring, and regulatory oversight that MTCA designation now requires.

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.
