This property has a documented history as a farm and agricultural operation going back to 1946. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.
This Spokane County municipal water supply site has operated since at least 1946, when its first well was constructed; a second well was drilled in 1980. Carbon tetrachloride was detected in routine groundwater monitoring in February 1989, leading to both wells being taken out of service in June 1990 and the development of an alternative municipal supply well in 1994, funded by an Ecology grant. Investigations conducted between 1997 and 2002 — a Contaminant Source Identification assessment and an Expanded Site Inspection — identified the Cenex Mead Grain Elevator, situated approximately a quarter mile from the well site, as a medium potential source; carbon tetrachloride was a historically common grain fumigant at such facilities. The site has appeared on the contaminated sites list since 1994, and no active remediation has yet commenced. 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.
Carbon tetrachloride contamination here is linked to grain fumigation operations — a use pattern investigators specifically identified at the Cenex Mead Grain Elevator, a named facility a quarter mile from the well site that was operating well before 1986. Occurrence-based Commercial General Liability policies issued to grain-handling operators at this specific site during that pre-1986 era covered the kinds of chemical releases now under investigation. With remediation not yet underway, the full cost of cleaning up the carbon tetrachloride plume that forced this municipal water supply offline still lies ahead — and historical carriers whose policies covered the Cenex Mead Grain Elevator's fumigation-era operations may bear an obligation to fund that upcoming work.
