This property has a documented history as a landfill going back to 1940. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup.
The Former Ruston Landfill accepted only municipal solid waste from the 1940s through 1957, when operations ceased. The site was included in a 1990 remediation effort as part of the broader ASARCO Plume cleanup; despite that work, the property remains on Ecology's Standard Cleanup list as Awaiting Cleanup, meaning that remediation sufficient to close the site has not yet been completed. Methane gas surveys conducted in 1995 and 2010 document persistent subsurface landfill gas conditions at the property. 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.
Landfill operations at this Ruston property ran from the 1940s through 1957 — entirely within the era when occurrence-based CGL policies carried no effective pollution exclusion. As Ecology's Standard Cleanup program advances this site toward active remediation, the investigation, design, and cleanup costs now ahead of the current owner are precisely the type of expenditures that historical CGL carriers, whose policies were in force during those 1940s–1957 operations, may be obligated to fund.
