Preliminary Site-Specific Analysis

This property has a documented history as a industrial and manufacturing facility predating 1986. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.

The Boeing Auburn Fabrication Facility operated as an industrial manufacturing site, with operations including metal fabrication, degreasing with trichloroethylene (TCE), and supporting functions such as x-ray and photographic laboratories. Contamination from historical use of TCE as an industrial degreaser prompted a comprehensive Remedial Investigation overseen by the Department of Ecology. An Interim Remedial Action was conducted from 2004 to 2006 to address residual TCE at the source location, and groundwater treatment through injection wells has been part of ongoing remediation efforts. Cleanup work at the site is continuing. 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.

TCE contamination at this facility originated from industrial degreasing operations that predate 1986, when occurrence-based Commercial General Liability policies were standard and carried no effective pollution exclusion in Washington. The site's documented remediation — source-area cleanup, groundwater injection treatment, and long-term monitoring — represents significant expenditures tied directly to those pre-1986 operations. Historical carriers who issued CGL policies during the facility's early operational decades may be obligated both to reimburse past cleanup costs and to fund remediation that remains underway.

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.
