About this Project
The Boardman to Hemingway Transmission Line Project (B2H Project) Environmental Impact Statement (EIS) has been prepared in response to an Application for Transportation and Utility Systems and Facilities on Federal Lands (Standard Form 299) submitted by Idaho Power Company (Applicant) to the Bureau of Land Management (BLM) and United States Forest Service (USFS), Department of the Navy (Navy), and the Bureau of Reclamation (Reclamation). The Applicant proposes to construct, operate, and maintain the B2H Project, which is an approximately 300-mile-long (depending on the route selected), single-circuit, 500-kilovolt (kV), alternating-current, overhead electric transmission line and ancillary facilities. The transmission line would connect the northern terminus, the Longhorn Substation, a substation planned by Bonneville Power Administration (BPA) approximately 4 miles east of the city of Boardman in Morrow County, Oregon, to the existing Hemingway Substation, near the city of Melba in Owyhee County, Idaho. The goal for the B2H Project is to provide additional electrical load capacity between the Pacific Northwest region and the Intermountain region of southwestern Idaho. The B2H Project would alleviate existing transmission constraints and ensure sufficient electrical capacity to meet present and forecasted customer needs.
The proposed B2H Project would cross federal, state, and private lands in five counties in Oregon and one county in Idaho. The proposed transmission line would cross federal lands administered by federal agencies, including the BLM and the USFS. The B2H Project would potentially affect lands and assets administered by the Reclamation and may affect lands of the Naval Weapons System Training Facility (NWSTF) Boardman and associated military Special Use Airspace administered by the U.S. Department of the Navy (Navy).

This EIS analyzes and discloses the impacts on federal, state, and private lands that may result from granting the federal agencies right-of-way to Idaho Power Company (the Applicant) to cross the federally managed lands for the purpose of constructing, operating, and maintaining the proposed 500 kilovolt (kV), single-circuit, alternating-current electric transmission line. The Agency Preferred Alternative for the new 500-kV transmission line begins at the proposed Longhorn Substation near Boardman in Morrow County, Oregon, and extends south and east to the existing Hemingway Substation in Owyhee County, southwest of Melba, Idaho, a distance of approximately 293 miles.
The B2H Project also includes:
• Constructing an internal communication system to control the transmission line and manage the flow of electricity, with regeneration sites approximately every 40 miles
• Relocating approximately 0.9 mile of existing 230-kV transmission line in the vicinity of Flagstaff Hill located east of Baker City, to allow for efficient placement of the 500-kV line
