This property has a documented history as a industrial and manufacturing facility going back to 1957. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
From 1957 to 1985, this Kent property housed a metal finishing and electroplating plant operated by Hytek Finishes Company and its predecessor, Heath Plating, manufacturing parts for the aerospace industry. Contamination from those decades of operations — including chlorinated solvents such as TCE — prompted an extensive remediation program that has included excavation and stabilization of contaminated soil and sludge, removal of a septic tank, and installation of groundwater and soil vapor extraction systems that operated for over a decade. Monitoring is ongoing, and cost evaluations for future cleanup alternatives have been documented. 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 contamination at this site traces directly to sludge lagoons and drum storage areas that were actively in use during the 1960s and 1970s — a period when occurrence-based Commercial General Liability policies were the industry standard and carried no effective pollution exclusion. Carriers who issued CGL coverage to Hytek Finishes or its predecessor, Heath Plating, during those operating years may bear obligations tied to the documented remediation costs: soil and sludge excavation, more than a decade of vapor extraction and groundwater treatment, and continuing monitoring. Because the contamination originated from those pre-1986 lagoon and drum-storage operations, historical policies from that window remain a plausible avenue for cost recovery.
