This property has a documented history as a industrial and manufacturing facility going back to 1936. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
This property was the site of sand pit mining and borrow pit operations conducted under multiple owners from at least 1936 through the early 2000s, during which approximately 1.3 million cubic yards of sand was extracted. Subsequent reclamation activities introduced approximately 36,000 cubic yards of fill material, and a whitish ash consistent with cement kiln dust — a byproduct of cement manufacturing — was deposited on the site. The property is enrolled in the Voluntary Cleanup Program; the recommended remedy includes a containment cap, an environmental covenant, and long-term groundwater and cap monitoring, with feasibility-level cost estimates for evaluated alternatives ranging from $649,000 to $10,879,000. 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.
The contamination at this property — metals, uncontrolled fill, and cement kiln dust — traces to industrial extraction and reclamation activities that began in 1936 and extended into the mid-1980s, placing the contamination origins squarely within the era of occurrence-based CGL policies that carried no effective pollution exclusion. Early site investigations confirming the contamination sources were already underway by 1985, establishing that the triggering events occurred during the pre-1986 policy window. The documented remediation cost range of $649,000 to nearly $11 million represents expenditures that historical carriers who issued CGL policies during the decades of active operations may be obligated both to recover and to fund going forward.
