State of Oregon: Facilities - Boardman to Hemingway Transmission Line

The Boardman to Hemingway Transmission Line is an approved facility that includes an approximate 300 mile (275 miles in Oregon) electrical transmission line (primarily 500 kilovolt (kV)) that crosses five counties in Oregon, Morrow, Umatilla, Union, Baker, and Malheur counties. Approved related or supporting facilities include the Longhorn Substation in Boardman, Oregon, communication stations, access roads, pulling and tensioning sites and construction laydown areas.

Approved. On September 27, 2022, Council approved the ASC. The approved but not yet constructed facility has a construction commencement deadline of October 6, 2026.

On December 7, 2022, the Department received preliminary Request for Amendment 1 (pRFA1) from the certificate holder. The pRFA1 seeks Council approval for the following:

re-location of the transmission line on three properties based on IPC's coordination and agreement with the affected landowners; and
refinement of the location of certain roads resulting from additional design and engineering review. This includes approximately 7.2 miles of 500-kV transmission line alternatives, and 33.8 miles of access road changes associated with the approved route. The proposed site boundary additions cover 952.5 acres.

Following review and completeness determination of pRFA1, the Department will issue a Draft Proposed Order and Notice of Draft Proposed Order, initiating a public comment period on both the amendment request and Draft Proposed Order. These materials will be posted to the project webpage below upon issuance.

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