Preliminary Site-Specific Analysis

This property has a documented history as a landfill going back to 1930. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

Area 1 of Naval Base Kitsap Keyport served as the base's primary disposal area for domestic and industrial wastes from the 1930s until the landfill was closed in 1973. Cleanup and monitoring efforts have been ongoing since at least 1993, encompassing excavation of contaminated soil and sediment, phytoremediation, landfill cover upgrades, tide gate improvements, and removal of structures. A 2022 pilot study evaluated High Vacuum Dual Phase Extraction and air sparging technologies for treating residual groundwater hotspots, and construction work is now complete with the site in performance monitoring. 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 this Naval base landfill began in the 1930s, more than four decades before the 1986 threshold after which occurrence-based CGL policies began carrying effective pollution exclusions. The contamination documented in soil, sediment, and groundwater here is the direct result of decades of industrial and domestic waste disposal that predates modern pollution liability frameworks entirely. Remediation expenditures — soil and sediment excavation, phytoremediation, infrastructure upgrades, and multi-year monitoring — represent costs that historical carriers who issued CGL policies during the landfill's operational window 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.
