This property has a documented history as a farm and agricultural operation going back to 1935. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
The Labrador Property operated as a working farm from 1935 through 1985, with dieldrin — an organochlorine insecticide — applied to the land during farming operations in the 1950s and 1960s. Cleanup under the Voluntary Cleanup Program has involved the excavation of between approximately 69,900 and 85,000 cubic yards of contaminated soil from the western parcel, which was then consolidated into a stockpile on the eastern parcel and capped with a polyethylene barrier and clean soil. Long-term groundwater monitoring has continued through at least 2019, with the multi-phase remediation project still under active site management. 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 dieldrin contamination at this property traces directly to pesticide applications during the 1950s and 1960s, decades before occurrence-based Commercial General Liability policies began carrying effective pollution exclusions. Agricultural operations responsible for that contamination were fully underway well before 1986, meaning the CGL policies in force during those years remain potentially enforceable today. The documented remediation expenditures here — excavation and removal of tens of thousands of cubic yards of impacted soil, engineered consolidation and capping, and years of ongoing groundwater monitoring — represent significant costs that historical carriers may be obligated both to recover and to fund as site management continues.
