ENVIRONMENTAL ASSESSMENT NON-CAPACITY AMENDMENT OF LICENSE
Stagecoach Hydroelectric Project Project No. 9202 Colorado

In accordance with the National Environmental Policy Act of 1969, as amended, and the Federal Energy Regulatory Commission’s (Commission) regulations (18 CFR Part 380),the Office of Energy Projects has prepared an environmental assessment (EA) regarding Upper Yampa Water Conservancy District’s (District) request for a non-capacity license amendment for the Stagecoach Project (FERC No. 9202) located on the Yampa River in Routt County, Colorado. The District requests Commission approval to amend the project’s license to (1) increase the height of the project dam spillway’s crest elevation by 4 feet, and (2) increase the maximum operating storage elevation of Stagecoach Reservoir by 4 feet. This would increase the maximum storage capacity in Stagecoach Reservoir from 33,275 acre-feet to 36,460 acre-feet, and increase the project’s potential for increasing downstream water supply. This EA concludes that the proposed license amendment, with staff’s recommended mitigation measures, would not constitute a major federal action significantly affecting the quality of the human environment.
