Vantage-Pomona Heights 230kV Transmission Line Project

About the Project

Pacific Power proposes to construct, operate, and maintain a new 230 kilovolt (kV) transmission line situated in south-central Washington, extending from the Bonneville Power Administration (BPA) Vantage substation located just east of the Wanapum Dam in Gant County to Pacific Power's Pomona Heights substation located just east of Selah, Washington in Yakima County. The project would cross private lands and federal lands.

The U.S. Department of the Interior, Bureau of Land Management (BLM) is the lead federal agency responsible for the preparation of the Draft EIS (DEIS) in consultation with cooperating agencies to analyze the effects of granting, granting with conditions, or denying Pacific Power's (the applicant) right-of-way applications to construct, operate and maintain a 230 kilovolt (kV) transmission line, associated access roads, and other ancillary facilities across federal lands. The U.S. Army - Joint Base Lewis McChord Yakima Training Center (JBLM YTC), U.S. Bureau of Reclamation (Reclamation), Bonneville Power Administration (BPA), and Yakima County are cooperating agencies and assisted with the preparation of the DEIS.

A total of eight transmission line route alternatives are considered in the DEIS, along with the "No Action" alternative. The eight end-to-end route alternatives range from 61 to 67 miles in length and cross portions of Benton, Grant, Kittitas, and Yakima Counties. The BLM has identified a preferred route for the new transmission line. The preferred route map is available in the DEIS document below.

Draft EIS

With the publication of the Notice of Availability in the Federal Register on January 4, 2013, the Draft EIS has been released to the public for comment and review. The BLM is soliciting written comments on the DEIS during the public comment period. The public comment period for the Draft EIS will close on Friday, March 8, 2013.

The Draft EIS is available in the Documents section below.

New Route Alternative Identified

The Bureau of Land Management (BLM) Spokane District has identified a new route alternative for the Vantage to Pomona Heights 230kV electrical transmission line project. As a result of public comments received after the January 2013 release of the Draft Environmental Impact Statement (DEIS) identifying a Preferred Alternative the BLM, Pacific Power, and the Yakima Training Center (YTC) met and identified a new route that is located largely on YTC land.

Information about the new route alternative is available in the Documents section below.
