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 the proposed Longhorn Substation in Boardman, Oregon to the existing Hemingway Substation in southwestern Idaho.
Proposed. On September 28, 2018, the Oregon Department of Energy (ODOE) received the complete Application for Site Certificate (ASC) for the proposed facility (see below). Public notice of the complete ASC and public information meetings was issued on October 3, 2018. The public information meetings were held the week of October 15-18, 2018 in Morrow, Umatilla, Union, Baker, and Malheur counties. A link to the presentation provided at the meetings is provided here. The Department is preparing the draft proposed order (DPO).

Electronic copies of the ASC materials may be downloaded or viewed at: Baker County Public Library, 2400 Resort St., Baker City; Oregon Trail Library District, 200 S. Main St., Boardman; Cook Memorial 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 the 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 Company (applicant) may request EFSC approval of any combination of route segments for the proposed facility. All route segments must meet all applicable EFSC standards, rules, and ordinances. These route segments may or may not align with the route segments identified in the Record of Decision (ROD) issued by the BLM from the NEPA review. On non-federal land in Oregon, the proposed facility requires EFSC approval. On federal land, the proposed facility requires approval of both the responsible federal agency and EFSC.

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