Proposed Transmission Line Avoids Kofa National Wildlife Refuge

Last week, the Bureau of Land Management announced a draft Environmental Impact Statement (EIS) for the proposed Ten West Link energy transmission project.

Statement by Rob Peters, Senior Southwest Representative, Defenders of Wildlife:

“The Bureau of Land Management’s proposed route for the Ten West Link avoids Kofa National Wildlife Refuge and the vital habitat it provides for the endangered Sonoran pronghorn as well as desert bighorn sheep, mountain lions, mule deer and many other species. That’s smart planning.

“Electrical transmission is essential for expanding renewable energy development in the West, and properly routed transmission lines help support responsibly-sited renewable energy facilities. We look forward to our continued engagement in the planning process to ensure that the project has minimum impacts on wildlife and wildlands.”


  • The Ten West Link transmission line is a 125-mile 500kV line from Arizona to California mostly along Interstate 10.
  • The project is proposed to connect existing substations near Tonopah, Arizona, and Blythe, California.
  • In 1936, the Arizona Boy Scouts mounted a statewide campaign to save the bighorn sheep, leading to the creation of Kofa National Wildlife Refuge.
  • On April 2, 1939, Kofa National Wildlife Refuge was officially opened.
  • Kofa is largely wilderness, with 80 percent of its 665,400 acres designated as the Kofa Wilderness in 1990.
  • Resident mammals include mule deer, bats,mountain lions, the ringtail cat, and the rareSonoran pronghorn, a species that Defenders has worked for decades to restore.
