Gateway West Transmission Line | Segments 8 and 9








The BLM is preparing a supplemental environmental impact statement (EIS) analyzing new information - not previously evaluated in the 
April 2013 final EIS - associated with the potential impacts of approving 
a right-of-way (ROW) application for segments 8 and 9 of 
the Gateway West 500-kilovolt (kV) 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 the new information in these revised documents warrants additional analysis and public review under the National Environmental Policy Act (NEPA).

The BLM published a Notice of Intent (NOI) on September 19, 2014, which initiated the scoping period for the supplemental EIS. During scoping, the BLM invites comments on issues, potential impacts, mitigation measures, and alternatives associated with granting rights-of-way on public lands for segments 8 and 9 that were not addressed in the 2013 final EIS.
