Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility going back to 1944. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

Naval Base Kitsap Bangor was established in 1944, with military operations — including ordnance disposal from 1962 to 1975 — generating contamination at multiple locations across the installation. The site was listed on the National Priorities List in 1987 for past waste disposal practices. Cleanup has included free product recovery, groundwater treatment systems, ordnance disposal, and installation of institutional and engineering controls such as caps, barriers, soil covers, and shoreline protection systems. Construction of remedial systems is complete, with long-term performance monitoring and maintenance ongoing. 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 installation originated from naval operations that began in 1944 — more than four decades before the 1986 shift away from occurrence-based Commercial General Liability coverage. Decades of remediation expenditures — groundwater treatment, free product recovery, engineered barriers, shoreline protection, and long-term monitoring — have been incurred to address releases tied to those pre-1986 operations. Historical CGL policies issued during the base's operational window may still carry obligations to recover past cleanup costs and fund the ongoing monitoring program.

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.
