This property has a documented history as a landfill going back to 1946. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
The Cornwall Avenue Landfill operated as a municipal solid waste disposal site from 1946 to 1965, during which the City of Bellingham used the property for the disposal of refuse; upon closure in 1965, the landfill was covered with a soil layer. Medical waste was deposited at or near the site between 1964 and 1986, and the site was leased through at least 1985. Completed remediation work includes a 2005 stormwater detention basin, site grading, historic landfill covering and shoreline armoring, and a 2011–2012 interim action that dredged 47,500 cubic yards of sediment to create a low-permeability cap over 4.5 acres and installed a landfill gas collection system. Future remediation alternatives still under evaluation include additional groundwater treatment, further soil removal, sediment capping, and monitored natural recovery. 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.
Waste disposal operations at this site began in 1946, and medical waste deposition continued through 1986 — placing the contamination-generating period squarely within the era when occurrence-based Commercial General Liability policies carried no effective pollution exclusion under Washington law. Carriers who issued CGL coverage to the City or to site lessees during that pre-1986 operational window may remain obligated for the documented remediation costs already incurred — dredging, capping, gas collection — and for the substantial additional expenditures the ongoing remediation alternatives represent.
