Boardman to Hemingway Transmission Line

The Boardman to Hemingway Transmission Line is a proposed transmission line – primarily 500-kilovolt – that would extend approximately 300 miles from Boardman, Oregon to the Hemingway Substation in southwestern Idaho.

Proposed. On July 19, 2017, the Oregon Department of Energy received the Amended Preliminary Application for Site Certificate for the facility. The application is available below. Electronic copies of the application materials may be viewed or downloaded at: Baker County Library, 2400 Resort St., Baker City; Boardman City Library, 200 S. Main St., Boardman; La Grande Public Library, 2006 4th St., La Grande; Pendleton Public Library, 502 S.W. Dorion Ave., Pendleton; Ontario Community Library Central, 388 SW 2nd Ave, Ontario; and Oregon Department of Energy, 550 Capitol St. N.E., Salem.

The B2H project website provides useful information and is the main repository of documents and information regarding the federal NEPA review. The ODOE webpage you are on is considered the official source of current information regarding the EFSC review.

Idaho Power may request EFSC approval of any combination of route segments for the proposed B2H facility. All route segments must meet all applicable EFSC standards and other applicable rules. These route segments may or may not align with the route segments selected for analysis by the BLM during its NEPA review. Off of federal land in Oregon, EFSC has responsibility for conducting the permitting review of the facility. On federal land, the proposed B2H facility needs approval of both the responsible federal agency and EFSC. 

Morrow, Umatilla, Union, Baker, Malheur, Owyhee (Idaho) counties.
