Chicago Milwaukee Corporation (CMC) Bozeman Asbestos Facility
Background
CMC Asbestos Bozeman (the Facility), at the 600 block of East Main Street in downtown Bozeman, is an inactive, 11-acre asbestos ore-loading location, which operated from 1953 to circa 1960. Recycling/salvage businesses also operated at the Facility from 1956 to 1988. Soils at the Facility are contaminated with asbestos from the ore-loading operations. Initial site contaminants also included heavy metals, polychlorinated biphenyls (PCBs), dioxins/dibenzofurans, and organic compounds (including petroleum) from the salvage operations. Soils containing the latter contaminants have since been removed under a voluntary cleanup plan, pursuant to the Voluntary Cleanup and Redevelopment Act, §§ 75-10-730 through 75-10-738, MCA.
The asbestos ore at the Facility originated from the Karst Mine near Big Sky and was stockpiled at the location of a mill on Wallace Avenue. Ore milled at the mine and at the Bozeman mill, called “Karstolite,” was used as insulation material and has been found in attics and walls of some buildings in Bozeman, Helena and Livingston.
Anthophyllite Asbestos Ore From The Karst Asbestos Mine
In the fall of 2001, the City of Bozeman purchased 14 acres of the Facility from CMC and remediation work on City-owned property was completed in October 2003. Asbestos ore contaminated soils on properties adjacent to the 14-acre City property remain in place. On December 21, 2006 the City of Bozeman agreed to act as the lead potentially liable person (PLP) under the Controlled Allocation of Liability Act (CALA) to complete remedial actions at the Facility, §§ 75-10-742 through 75-10-751, MCA. A stipulated agreement between the noticed PLPs was signed in August, 2007.
The City of Bozeman completed supplemental investigation field work focused on contamination on the adjacent properties in December 2007.
