This property has a documented history as a industrial and manufacturing facility predating 1986. 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, with the Bunker Hill Mining & Metallurgical Complex and associated mines discharging waste directly into the South Fork of the Coeur d'Alene River and its tributaries until approximately 1968; an estimated 62 million tons of tailings containing arsenic, cadmium, lead, and zinc entered the waterway before that year. Those sediments migrated downstream through Lake Coeur d'Alene and into the Spokane River, ultimately depositing along the Myrtle Point shoreline. A USEPA Record of Decision issued in 2002 set out the remedial approach, and cleanup activities from 2006 through 2012 included excavation of contaminated river sediments and capping with gravel, sand, and soil, supplemented by native vegetation plantings for erosion control. The site is currently in the operations-and-maintenance phase, with long-term monitoring and five-year periodic reviews 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 heavy-metal contamination at this property traces entirely to industrial discharge that ceased around 1968 — nearly two decades before occurrence-based Commercial General Liability policies began carrying effective pollution exclusions. Operators of the Bunker Hill complex and affiliated mining entities who held CGL policies during those decades of active discharge would have been covered under policies that imposed no meaningful bar to pollution claims. The documented remediation expenditures here — sediment excavation, engineered capping, and a continuing long-term monitoring obligation — are costs directly attributable to those pre-1986 operations, establishing a plausible basis for historical carriers to fund or share in their recovery.
Restorical's role is to locate viable historical policies, determine whether a successful coverage claim is possible, and assist our clients and their legal counsel to obtain insurance coverage. Restorical then manages the claim, including accounting, to ensure the cleanup is funded in a timely manner.
