This property has a documented history as a industrial and manufacturing facility going back to 1907. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
The Klickitat Valley Sawmill has operated on this approximately 300-acre property since about 1907, with industrial activities including lumber treatment via a pentachlorophenol dip tank, an on-site bulk fuel facility, oil storage and paint facilities, and maintenance and locomotive shops where oils, solvents, and cyanide were reportedly used. Cleanup under the Voluntary Cleanup Program has included excavation and offsite disposal of contaminated soil, with interim actions and investigations documented from at least 2002, a restrictive covenant established in 2004 for areas retaining residual contamination, and periodic monitoring confirmed as recently as 2021. Cleanup work is ongoing. 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.
Operations at this site trace back more than a century, with the contamination profile — pentachlorophenol, petroleum hydrocarbons, oils, solvents, and cyanide — reflecting industrial practices that long predate 1986. Occurrence-based Commercial General Liability policies issued to Champion International, St. Regis Paper Company, and prior operators during the pre-1986 decades had no effective pollution exclusion under Washington law and remain enforceable today. The documented remediation expenditures — soil excavation, covenant implementation, and nearly two decades of ongoing monitoring — represent costs those historical carriers may be obligated both to recover and to fund going forward.
