BLM Seeks Public Input on Proposed Gateway South Transmission Line Project

The Bureau of Land Management (BLM) is seeking public comment on an environmental impact statement (EIS) that will evaluate the potential impacts of constructing the Gateway South 500-kilovolt (kV) alternating current (AC) transmission line project, which is proposed to cross portions of Colorado, Utah and Wyoming.

The project is proposed by PacifiCorp, doing business as Rocky Mountain Power. The announcement was published in the Federal Register on April 1 and initiates a 90-day public scoping period. Rocky Mountain Power proposes construction of a high-voltage overhead transmission line that would extend about 400 miles, depending on the route selected, from south-central Wyoming to central Utah, potentially crossing northwestern Colorado.

The transmission line would begin near Medicine Bow, in Carbon County, Wyoming, at the planned Aeolus Substation, and would extend south and west to the planned Clover Substation, near Mona, in Juab County, Utah. The project would also include two series compensation stations, about 200 acres in size, at two separate points between the planned Aeolus and Clover Substations to improve transport capacity and efficiency of the transmission line. When completed, the project would transmit about 1,500 megawatts of electricity generated from renewable and thermal sources at planned facilities in Wyoming. Alternative routes identified so far would cross federal, state, tribal, and private lands.

Authorization of this proposal may result in the amendment of U.S. Forest Service (USFS) and BLM land and resource management plans.

The BLM expects to host 12 open-house meetings at various locations in Wyoming, Colorado and Utah along the proposed corridor to provide the public an opportunity to review the proposal and project information. Staff and project proponents will be available at each open house to explain project details and gather information from interested individuals or groups.

Through the scoping process, the BLM expects to gather public input on resources and issues that should be addressed in the EIS, including route alternatives that should be analyzed in detail in the EIS and sources of information that may be used in the environmental analysis. The USFS and other cooperating agencies are expected to participate in the public meetings.

All open-house meetings will be held from 4:30 – 7:30 p.m. on the following schedule:

  • May 10: Valley Community Center, 255 W. Osborne, Baggs, Wyo.
  • May 11: Rock Springs High School, 1375 James Drive, Rock Springs, Wyo.

BLM manages more than 245 million acres – more land than any other Federal agency. This land, known as the National System of Public Lands, is primarily located in 12 Western states, including Alaska.В  The Bureau, with a budget of about $1 billion, also administers 700 million acres of sub-surface mineral estate throughout the nation. The BLM’s multiple-use mission is to sustain the health and productivity of the public lands for the use and enjoyment of present and future generations. The Bureau accomplishes this by managing such activities as outdoor recreation, livestock grazing, mineral development, and energy production, and by conserving natural, historical, cultural, and other resources on public lands.
