This property has a documented history as a industrial and manufacturing facility going back to 1960. Historical insurance policies issued during operations at this property and through 1986 could fund a cleanup — and recover costs already spent.
TrueGuard LLC operates as an active wood treating facility on an approximately 21-acre parcel in Washougal, within an industrial park developed in the 1960s. The facility uses copper-chrome-arsenate (CCA) solution in its treating process; a cracked foundation beneath the main retort is identified as the source of arsenic contamination in shallow groundwater. Cleanup activities under the Voluntary Cleanup Program have included foundation repairs in 2007, multi-year groundwater monitoring from 2007 through 2016, and pilot testing of Air Sparging, EHC-M injection, and geochemical fixation with persulfate and red mud between 2008 and 2010. A full-scale horizontal Air Sparging system has been proposed, with up to five years of additional monitoring planned. 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.
CCA wood treating operations at this facility trace to the 1960s — predating by two decades the policy shift that made pollution exclusions standard — and the arsenic contamination here originated from a structural release tied directly to those long-running treating operations, not a recent event. More than a decade of investigation, pilot remediation, and ongoing groundwater monitoring under the VCP has accumulated around a release whose origin sits squarely in the pre-1986 operational window. Historical carriers who issued CGL policies to TrueGuard's CCA treating operations during that era may bear responsibility for a cleanup that remains unfinished.
