This property has a documented history as a landfill going back to 1939. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property in Kelso served as a dump site where fill material — petroleum hydrocarbons, creosote-treated wood waste, asphalt, and miscellaneous debris — was emplaced between 1939 and 1978. The contamination was discovered in 2005 when a sewer installation encountered the impacted fill in the northwest area of the property along Corduroy Road. Cleanup under the Voluntary Cleanup Program included removal of 200 cubic yards of contaminated soil and 70 wooden piles in 2005, followed by groundwater monitoring from 2005 through 2014; future remediation alternatives under consideration include institutional controls, additional soil excavation, and in-situ groundwater treatment using oxidizing agents. 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 property traces directly to fill operations conducted over four decades — from 1939 to 1978 — spanning a period when occurrence-based Commercial General Liability policies had no effective pollution exclusion. Parties responsible for emplacing petroleum hydrocarbons and creosote-laden wood waste during that window may have maintained CGL coverage that remains enforceable today. The documented remediation expenditures to date — soil excavation, pile removal, and nearly a decade of groundwater monitoring — as well as the anticipated costs of further excavation and in-situ treatment, represent obligations that historical carriers may be required both to reimburse and to fund going forward.
