Industrial & Manufacturing cleanup site — Restorical Research
BSB Hexcel

Restorical Research
Preliminary Site-Specific Analysis

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

Prior to 1988, this Kent industrial property housed two divisions of BSB: the Hytek division, which provided metal finishing and electroplating services, and the Heath Tecna Aerospace Company division, which manufactured interior aircraft components — with hazardous substances in active use across multiple manufacturing buildings. Contamination from those operations has triggered a Standard Cleanup under Washington Ecology, encompassing closure of waste management units, ongoing site investigations and monitoring, and a groundwater pump-and-treat system currently operating under a permit initially issued for ten years and since extended indefinitely. Hexcel continues to pursue aircraft parts manufacturing at the property today. 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.

The chlorinated compounds — including TCE, a hallmark of industrial metal finishing and degreasing — detected in groundwater here originated from manufacturing operations that were well established before 1986, when occurrence-based CGL policies were standard and carried no effective pollution exclusion in Washington. The documented remediation at this site — waste unit closures, reimbursement agreements tied to historical disposal, and a pump-and-treat system with no defined end date — represents both past expenditures and an open-ended forward cost stream traceable to those pre-1986 hazardous substance activities. Historical carriers who issued CGL policies during BSB's operational window may be obligated to contribute to costs already incurred and to fund the ongoing groundwater treatment still 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.
