This property has a documented history as a industrial and manufacturing facility going back to 1928. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
The Weyerhaeuser Longview facility began operating as a plywood mill in the late 1920s, with key log-handling equipment — offshore barkers, onshore lathes, and clippers — installed between 1947 and 1962; the property also included a chlor-alkali facility with a dedicated mercury cell room. Soil contamination resulted from decades of hydraulic oil leakage and spillage from log-handling machinery and mercury releases from the chlor-alkali operations. An independent demolition and cleanup of the mercury cell room was conducted between 1990 and 1991, followed by broader remedial actions mandated under an Agreed Order and Consent Decree requiring containment and disposal of hazardous substances. Ongoing operation, maintenance, and monitoring of the cleanup action remain required, with Weyerhaeuser responsible for Ecology's costs. 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.
Plywood milling and chlor-alkali chemical manufacturing at this property ran from the late 1920s through at least the late 1980s — a six-decade operational span that entirely predates the 1986 shift away from occurrence-based CGL coverage. Occurrence-based Commercial General Liability policies issued to Weyerhaeuser during that window carried no effective pollution exclusion and remain enforceable against historical carriers. The site's documented remediation costs — mercury cell room demolition, hazardous substance containment and disposal, and continuing operation and maintenance obligations — represent expenditures those historical carriers may be obligated both to recover for past work and to fund going forward.
