Gateway West Transmission Line | Segments 8 and 9








The BLM is preparing a supplemental environmental impact statement (EIS) analyzing new information associated with the potential impacts of approving a right-of-way (ROW) application for segments 8 and 9 of the Gateway West transmission line project.

On August 8, 2014, Rocky Mountain Power and Idaho Power submitted a revised application and revised plan of development for segments 8 and 9. The BLM has determined that this new information warrants additional analysis and public review under the National Environmental Policy Act.

A total of 740 individual comments were identified in the 74 letters/cards, 
36 emails and 3 phone calls received during public scoping.  Comments that are substantive and that relate to the new information in the project application are being used to outline the analysis in the draft supplemental EIS.  Substantive comments identify issues – points of disagreement, debate or dispute with the proposed action that is based on some anticipated environmental effect. Comments that express opinions or preferences do not have effects that can be analyzed in an EIS and so are considered during other phases of the decision-making process.
