This property has a documented history as a industrial and manufacturing facility going back to 1890. Historical insurance policies issued during those prior operations and through 1986 could fund a cleanup — and recover costs already spent.
Mining operations in the Coeur d'Alene Basin of northern Idaho began in the late 1800s, extracting silver, zinc, and lead while discharging mine waste directly into the South Fork of the Coeur d'Alene River until approximately 1968. That multi-decade discharge deposited heavy metals — arsenic, cadmium, lead, and zinc — in sediments along the Spokane River shoreline. The U.S. EPA issued a Record of Decision in 2002 under the Bunker Hill Mining & Metallurgical Complex framework, and Washington State cleanup activities commenced in 2006, involving excavation and capping of contaminated sediments at multiple shoreline sites, vegetation plantings, and access restrictions; long-term monitoring and periodic reviews remain ongoing. 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 arsenic, cadmium, lead, and zinc contamination at the Spokane River shoreline is a direct product of Coeur d'Alene Basin mining and metallurgical operations that ran continuously from the late 1800s through approximately 1968 — decades before occurrence-based Commercial General Liability policies began carrying effective pollution exclusions. Operators of the Bunker Hill Mining & Metallurgical Complex held CGL policies throughout that pre-1986 industrial window, and those policies remain enforceable against the releases they covered. The documented remediation costs — sediment excavation and capping across multiple shoreline sites, vegetative stabilization, and decades of monitoring — represent expenditures the historical carriers may be obligated to fund.
