Preliminary Site-Specific Analysis

This property has a documented history as a public works and maintenance facility going back to 1910. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

This property served as the Camp Bonneville Military Reservation, operated by the U.S. Department of the Army from the early 1900s through 1995. Between 1910 and 1995, the Army used the site for live fire of small arms, assault weapons, artillery, and field and air defense artillery, with additional training and disposal operations conducted by the Portland Air National Guard, local fire departments, and law enforcement. Cleanup under a Standard Cleanup program is ongoing, including extensive groundwater monitoring, soil excavation for source removal at landfill and disposal areas, active remediation of lead contamination at small arms ranges, and initial planning for excavation at newly discovered disposal areas. 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.

Decades of military training, live-fire exercises, and disposal operations at this site generated contamination — including lead from small arms ranges — that originated well before 1986. Occurrence-based CGL policies in effect during those pre-1986 operational years carried no effective pollution exclusion under Washington law and remain enforceable today. With cleanup actively underway and additional excavation being planned, the documented remediation expenditures and projected future costs represent obligations that historical carriers may be required both to reimburse and to continue funding.

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.
