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.

Western Pneumatic Tube Company's manufacturing facility at this Kirkland property used trichloroethene (TCE) in degreasing operations conducted in Building #2; an annealing oven and pickling tanks documented on the site plan corroborate the industrial character of those operations. TCE contamination was identified as far back as 2009, and the site is currently enrolled in the Voluntary Cleanup Program. Remediation in 2023 centered on the continued operation of a Sub-Slab Depressurization system, the installation of three 200-pound granular activated carbon vessels for vapor treatment, removal of approximately 3.0 pounds of TCE, and management of 600 pounds of spent hazardous carbon, with annual status reporting 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.

The degreasing operations in Building #2 — the identified source of the TCE release at this site — establish a discrete, localized occurrence that predates 1986 by decades, when occurrence-based CGL policies were standard for industrial manufacturers. Carriers who insured WPT's operations during the active degreasing era in Building #2 potentially remain obligated to respond to contamination traced directly to that activity. The site's documented and continuing remediation costs — vapor extraction infrastructure, repeated carbon vessel replacements, and annual monitoring commitments — represent expenditures that those historical carriers may be required 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.
