Kennecott Utah Copper LLC


The operational and environmental cleanup activities at Kennecott Utah Copper LLC's (Kennecott) Bingham Canyon Mine, Copperton Concentrator, Smelter, Refinery, Tailings Facility and the various ancillary facilities are regulated under a number of federal and State programs with authority to oversee the work pursued by Kennecott and other third parties. The federal and State agencies draw their authority from a number of federal statutes, including the Comprehensive, Environmental Response Compensation and Liability Act (CERCLA) of 1980, the Clean Water Act (CWA) of 1972, and the Clean Air Act (CAA) of 1970, as well as State of Utah environmental protection acts.

The U.S. Environmental Protection Agency (EPA) Region 8 has the authority under CERCLA (i.e., Superfund) to oversee the cleanup of historical mining contaminated areas at the Kennecott properties. The Utah Division of Environmental Response and Remediation (DERR) works in partnership with EPA to oversee Kennecott's environmental cleanup activities.

Starting in the late 1980s, the State of Utah Natural Resource Damage Trustee (NRD Trustee) has overseen the investigation of mining influenced groundwater and the implementation of cleanup actions performed by Kennecott and the Jordan Valley Water Conservancy District (JVWCD) to address two groundwater plumes located in Southwest Salt Lake County. The plumes were caused by historic mining practices in the Kennecott South Zone. The NRD Trustee's authority is derived from Section 107(f) of CERCLA.

As authorized by the State Legislature under the Utah Water Quality Act (Title 19, Chapter 5 of the Utah Annotated Code), the Division of Water Quality (DWQ) enacted rules for the protection of groundwater. DWQ regulates potential discharges to aquifer systems within the State of Utah, including a number of locations at Kennecott under the Utah Ground Water Protection Program (GWPP).

DWQ implements the Utah Pollution Discharge Elimination System program (UPDES), which oversees the discharge of water from a number of outfall locations at Kennecott. DWQ is authorized under the CWA to implement the UPDES program.

As authorized by the State Legislature, under the Utah Air Conservation Act (Title 19, Chapter 2 of the Utah Annotated Code), the Division of Air Quality (DAQ) regulates the emissions from Kennecott's Bingham Canyon Mine, Copperton Concentrator, Power Plant, Laboratory, Tailings Impoundment, Smelter, and Refinery facilities.

The Division of Waste Management and Radiation Control (DWMRC) provides oversight of the generation, transportation, treatment, storage, and disposal of hazardous waste regulated under the Utah Hazardous Waste Management Act or RCRA, as it pertains to the Kennecott facility. This includes oversight of rules related to hazardous substance or materials that when released or spilled become a hazardous waste.
