Proposed Action

Idaho Power Company and PacifiCorp (doing business as Rocky Mountain Power), collectively known as the Proponents, applied to the Bureau of Land Management (BLM) for a right-of-way (ROW) grant to use the National System of Public Lands for portions of the Gateway West Transmission Line Project (Gateway West or Project) on May 7, 2007. The original application was revised in October 2007, August 2008, May 2009, and January 2010 to reflect changes and refinements in their proposed Project. This application was assigned the case file numbers of IDI-35849 for Idaho, NVN-089270 for Nevada, and WYW-174598 for Wyoming.

The Proponents propose to construct and operate approximately 1,103 miles of new 230-kilovolt (kV) and 500-kV electric transmission system consisting of 10 segments between the Windstar Substation at Glenrock, Wyoming, and the Hemingway Substation approximately 30 miles southwest of Boise, Idaho. The proposed transmission line would supplement existing transmission lines and relieve operating limitations, increase capacity, and improve reliability in the existing electric transmission grid. This would allow for the delivery of up to 3,000 megawatts (MW) of additional energy for the Proponents’ larger service areas, principally in Utah and Idaho, and to other interconnected systems. The Project includes three proposed substations, an expansion at one planned substation to be constructed for other purposes, and expansions at eight existing substations. Other associated facilities include communication systems, optical fiber regeneration stations, and substation distribution supply lines.

Conditions of Approval

Although the BLM is issued a ROW grant for Gateway West, there are a number of details concerning project design, construction, and mitigation actions that are not finalized. These include 1) the POD covering project-wide practices and requirements, 2) the PODs for specific construction spreads, and 3) final mitigation plans associated with sage-grouse, migratory birds, wetlands, and cultural resources. Issuance of the ROW grant establishes in time the Proponents’ right to use the authorized public lands to construct, operate, maintain, and eventually decommission a high-voltage electric transmission line and associated facilities. The ROW grant holders will pay rent in accordance with 43 CFR 2806 from the date the grant is issued. However, they are not permitted to use the granted areas for the proposed project until the actions listed in Section 1.7 of the ROD are completed. The BLM controls delayed project starts through the NTP process contained in 43 CFR 2807.10 and the associated BLM Manual.

Data Completion Notes

BLM Wyoming has issued a ROD for Project Segments 1-7 and 10. A Supplemental EIS is being prepared for segments 8 and 9 by BLM Idaho. SEIS released March 2016.

More information about this process is available at: http://www.blm.gov/id/st/en/prog/nepa_register/gateway-west/Documents.html

Public comment for the Final EIS is open until June 9th, 2016.
