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.
This Kent manufacturing facility has been in continuous industrial operation since before 1986, first under Ciba-Geigy (including Heath Tecna) and then under Hexcel Corporation, which acquired the site in 1995. Environmental investigations have been ongoing since the late 1980s, with groundwater plume delineation work dating to 1988 and a joint pump-and-treat system agreement established in 1989. Cleanup measures include historical and ongoing groundwater extraction, installation of a low-permeability slurry wall, and current and planned Enhanced In Situ Bioremediation and Monitored Natural Attenuation programs, with estimated costs for proposed remedial alternatives ranging from $200,000 to $2,600,000. 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 site is attributed to historical chlorinated solvent disposal that predates 1986 — the year occurrence-based Commercial General Liability policies with no effective pollution exclusion were superseded by the modern exclusionary form. Ciba-Geigy and Hexcel each operated the facility during the period when that contamination was being identified and addressed under earlier policy structures. The documented remediation costs — slurry wall installation, decades of groundwater extraction, bioremediation programs, and long-term monitoring — represent expenditures that historical carriers may be obligated both to recover and to fund as cleanup continues.
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.
