註釋The Final Environmental Impact Statement (FEIS) responds to comments received during the public comment period on the Draft Environmental Impact Statement (DEIS) which analyzed impacts due to continuation and expansion of gold mining operations on a site in northeastern Nevada and identifies mitigation to be implemented to eliminate or reduce impacts associated with the proposal. The Proposed Action includes: 1) mining 775 feet below the groundwater level in a currently operating open pit mine; 2) dewatering the mine (up to 42,000 gallons per minute) and discharging warm groundwater directly into Maggie Creek, six miles above the confluence with the Humboldt River; 3) mining two new open pit mines; 4) constructing ancillary mine facilities; and 5) constructing a new haul road for transport of ore from a private mine north of the project area. Three alternatives to the Proposed Action were analyzed in the DEIS. The Agency Preferred Alternative has been revised in response to Newmont's Mitigation Plan and includes all components of the Proposed Action with implementing methods and procedures to maintain temperature of discharge waters within 2 degrees Celsius of Humboldt River water at the confluence with Maggie Creek and stabilize Maggie Creek channel to transport discharge water without adverse environmental effects. Newmont's mitigation plan provides for extensive monitoring of groundwater drawdown; implementation of flow augmentation programs to maintain water levels in springs, seeps, and streams as needed; immediate implementation of riparian habitat restoration programs; off-site restoration of Lahontan cutthroat trout habitat; haul road modifications for mule deer migration; off-site seedings for mule deer; and reclamation.
