Midway-Moxee Rebuild and Midway-Grandview Upgrade Transmission Line Project
(formerly the Midway-Moxee Transmission Line Rebuild)
Benton and Yakima counties, Washington
BPA is proposing to rebuild its 34-mile long Midway-Moxee transmission line and its 26-mile long Midway-Grandview transmission line. Both lines are 115-kilovolt (kV) wood-pole lines located in Benton and Yakima counties, Washington (see the project vicinity map). The lines were built in the 1940s and are deteriorating due to age and need to be rebuilt to ensure reliable electric service. In addition, the Midway-Grandview line would be upgraded to increase the electrical capacity to allow local utilities to meet increased demand for power.
For both lines, the project would include replacing all wood-pole structures and conductor (wires), improving existing access roads, and creating new access if needed. Most structures would be replaced with similar size poles next to the existing location unless changes are needed for safety or to minimize potential environmental impacts. Both lines would continue to operate at 115-kV. The upgrades for the Midway-Grandview line would also include replacing some electrical equipment within three existing substations.
A public scoping letter was sent on September 27, 2013. The comment period closed on October 31, 2013. Comments will be posted in their entirety on BPA's website at Midway-Moxee Rebuild and Midway-Grandview Upgrade Transmission Line comments
To understand the potential environmental impacts of this proposal, BPA will prepare an environmental assessment (EA). BPA started the environmental review for the Midway-Moxee rebuild in early 2013, but has now combined the review of the two lines because they run adjacent to one another for about five miles. Concurrent review and construction of the adjacent line section, if the decision was made to rebuild the lines, will save time, money, and result in less environmental impacts.
