Colorado Highlands Wind Project
Western Area Power Administration, Rocky Mountain Region (Western) has received a request from Colorado Highlands Wind to modify its Interconnection Agreement for the Colorado Highlands Wind Project (Project). The modification includes expanding the existing Colorado Highlands Wind Farm by adding 11 wind turbine generators (WTGs) on approximately 1,200 acres of State and private land adjoining the eastern border of the existing Project. The electricity produced by the additional WTGs would be about 20 megawatts (MW) and would be transferred to Western’s Sterling-Frenchman Creek 115-kilovolt transmission line at Western’s Wildhorse Creek Switchyard.The Project and the Project modification are located northeast of the Town of Fleming in Logan County, Colorado. As with the Project, the maximum blade tip height for the wind turbines for the modification is approximately 427 feet (130 meters). Other components of the modification would include underground electrical systems and access roads.
Western completed an environmental assessment and Finding of No Significant Impact in 2009 for the Project.
Western’s current proposal to modify the Interconnection Agreement for the Project fits within a class of actions that normally require preparation of an environmental assessment, specifically section C7 of Appendix C to Subpart D of 10 C.F.R. Part 1021, the Department of Energy National Environmental Policy Act Implementing Procedures.
In accordance with Western's responsibilities under section 5.a.(8) of the Department of Energy (DOE) Order 451.1B, National Environmental Policy Act (NEPA) Compliance Program, Western has determined that the modification to the Colorado Highlands Wind Project requires the preparation of a supplemental Environmental Assessment (SEA).
A draft Supplemental Environmental Assessment for the project has been prepared and can be viewed below.
