This property has a documented history as a industrial and manufacturing facility going back to 1900. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property served as a lumber mill operated by Weyerhaeuser and other wood products companies, with sawmill operations on both upland and in-water portions of the site beginning before 1900. Facility operations included log debarking, sawing, planing, and treating lumber, with pentachlorophenol (PCP) in use until 1986. Weyerhaeuser operated several sawmills and associated support facilities through January 2009. Cleanup activities under the Standard Cleanup program have included removal of an underground storage tank in 1989, management of investigation-derived waste, stormwater system cleaning in 2015, demolition of the Planer Building in 2022, and multi-year groundwater monitoring conducted from late 2019 through mid-2021. 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.
Sawmill and lumber-treating operations at this site began more than eight decades before 1986, when occurrence-based Commercial General Liability policies were still the industry standard and carried no effective pollution exclusion. PCP was used in lumber-treating operations at the facility through 1986 itself, placing the full arc of chemical usage squarely within the coverage window. The documented remediation expenditures — tank removal, waste management, building demolition, stormwater cleanup, and years of groundwater monitoring — represent costs the historical carriers may be obligated both to recover and to fund as cleanup continues.
