.':IEIS-0116-FS COVER SHEET DOE/EIS-0 I 16-FS Final Supplemental Environmental Impact Stat ement for the Blue River-Gore Pass Portion of the Hayden-Blue River Transmission Line Proj ect • Grand and Summit Counties, Colorado Lead Agency U.S. Department of Energy, Western Area Power Administrat ion Cooperating Agencies U.S. Department of Agriculture, Forest Service U.S. Department of Agriculture, Rural Electrification Administrat ion U.S. Department of the Interior, Bureau of Land Management Abstract This environmental impact statement (EIS) assesses the environmental effects of constructing, operating, and maintaining about 30 mi les of 230/345-kV trans mission line between the existing Gore Pass Substat ion northwest of Kremmling, Colorado, and a proposed new substat ion (not part of this action) near the Ute Pass Road. The action includes minor work at the Gore Pass Substation and at two taps, and also the removal of two existing transmission lines; a 69-kV line between Gore Pass Substation and Green Mountain Power Plant and a 1 15-kV line between Green Mountain Power Plant and Blue River Tap. The purpose of the project is to provide additional transmission capacity into the areas of Gore Pass, Granby, Green Mountain, Dillon, Climax, Oak Creek, and Keystone, and between the generation plants in western Colorado and the major load areas in eastern Colorado. Alternat ives assessed include routing and design alternatives plus the alternatives addressed in the Hayden-Blue River Final EIS, issued by the Rural Electrification Administration in July, 1982.

CHANGES & ADDITIONS TO THE DSEIS CHAPTER I - SUMMARY AND INTRODUCTION A. PROJECT BACKGROUND The Western Area Power Administration (W estern) in cooperation with the Bureau of Land Management (BLM) and the For est Service (F S) has developed a supple mental environmental impact statement (E IS) for the Blue River-Gore Pass por tion of the Hayden-Blue River transmission line project. This supplemental EIS , addresses specific corridor routings within the Williams Fork and Blue River drainages, each previously designated as environmentally pref erred and environ mentally acceptable corridors, respectively, by the Rural Electrification Admin istration (REA).
