This property has a documented history as a landfill going back to 1917. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property operated as a municipal landfill from 1917 to 1974, when it stopped accepting waste and was graded and closed the following year. Tire storage at the closed landfill began in 1977, and tire fires in 1983 and 1984 deposited ash and combustion residues across the site; a problem assessment in 1985 confirmed tire fire ash contamination. Remediation under the Voluntary Cleanup Program has included excavation of sediments, tires, and tire fire ash; installation and continuous operation of leachate collection and groundwater monitoring systems; landfill capping with geomembrane covers; landfill gas collection and monitoring; chemical fixation; and institutional controls — with multi-year project work documented since at least 1994. The site has achieved cleanup completion and is currently in active operations and maintenance monitoring. 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.
Every contamination-generating event at this property — fifty-seven years of municipal waste disposal, post-closure tire storage, and the 1983 and 1984 tire fires — preceded 1986, the threshold year after which occurrence-based Commercial General Liability policies began carrying enforceable pollution exclusions. The municipal operators who ran the landfill from 1917 through its 1974 closure, as well as parties responsible for subsequent tire storage and the resulting fire events, would have held CGL policies with no effective pollution bar under Washington law. The documented remediation costs here — excavation, capping, leachate management, landfill gas systems, and years of ongoing monitoring — represent expenditures that the historical carriers who issued those pre-1986 policies may still be obligated to recover.
