Daily Rules, Proposed Rules, and Notices of the Federal Government
PacifiCorp, doing business as Rocky Mountain Power (Proponent), has filed applications for a right-of-way across lands administered by the BLM and a special use permit across lands administered by the United States Forest Service (USFS) and is proposing to construct, operate, and maintain the Project, a single-circuit, alternating current 345-kV, overhead transmission line. If approved, the BLM would issue a right-of-way grant and the USFS would issue a special-use permit authorization for the transmission line and associated facilities. The transmission line would be located between the existing Sigurd Substation near Richfield in Sevier County, Utah, and the existing Red Butte Substation near the community of Central in Washington County, Utah, a distance of approximately 170 miles, depending on the route selected. The Project also includes the addition of new substation equipment for interconnecting the transmission line at the existing Sigurd Substation. When completed, the Project would provide about 600 megawatts of electrical capacity to respond to anticipated load growth in southwestern Utah. Alternative routes considered in the Final EIS cross Federal, State, tribal, and private lands. The requested right-of-way width on Federal lands for construction and operation of the Project is 150 feet. The Proponent plans to use predominantly steel-pole H-frame tower structures from 80 to 140 feet in height with average spans between structures of 800 to 1,200 feet (5 to 7 structures per mile). Permanent and temporary access roads, a minimum of 14-feet wide, would be needed for the majority of the Project. Temporary access roads would be needed for construction only. Temporary work space would be needed during construction for material storage, conductor tensioning sites, and to accommodate vehicles and equipment.
Under Federal law, the BLM is responsible for responding to applications for rights-of-way on BLM-administered lands. Similarly, under Federal law, the USFS is responsible for responding to applications for special-use permits on lands they administer. In accordance with NEPA, the BLM prepared a Draft EIS using an interdisciplinary approach in order to consider a variety of resource issues and concerns identified during internal, interagency, and public scoping. An updated inventory of lands with wilderness characteristics was used for this project and lands with wilderness characteristics were analyzed in the Draft EIS and Final EIS. An NOA for the Draft EIS for the Project was published by the EPA in the
BLM is the designated lead Federal agency for preparation of the EIS as defined at 40 CFR 1501.5. Agencies with legal jurisdiction or special expertise participating as cooperating agencies in preparation of the EIS include: USFS (Dixie and Fishlake National Forests); United States Army Corps of Engineers; National Park Service; the State of Utah; Utah School and Institutional Trust Lands Administration; Millard, Sevier, Beaver, Iron, and Washington Counties, Utah; and the cities of St. George and Enterprise, Utah.
In response to Section 368 of the Energy Policy Act of 2005 (42 U.S.C. 15926), a Programmatic EIS was prepared by the Department of the Interior and Department of Energy for energy corridors in the 11 Western states (including Washington, Oregon, Idaho, Montana, Wyoming, California, Nevada, Utah, Colorado, Arizona, and New Mexico). An NOA of the Final Programmatic EIS was published in the
