The Bonneville Power Administration (BPA) is proposing to upgrade parts of its existing high voltage transmission system in Montana, Idaho, and Washington. The proposal is in response to recent customer requests for increased transmission service capacity from BPA’s Garrison Substation in Western Montana to load centers west of the Cascades and to market hubs serving the entire Northwest power market.  The proposed upgrades would help BPA accommodate requests for transmission service without having to build any new high voltage transmission lines.

To understand the potential environmental impacts of this proposal, BPA will prepare an Environmental Impact Statement (EIS) pursuant to the National Environmental Policy Act.  EIS will describe anticipated impacts to natural and human resources and include mitigation measures to avoid or minimize impacts.  During this process, BPA will work with federal, state and local agencies, tribes, landowners, and interest groups.

BPA held a series of public meetings to solicit comments on the scope of this proposed project in May through June, 2012. The scoping comment period closed on July 2, 2012 and the comments that were received can be seen in their entirety at    

In response to the comments received during scoping, BPA is considering new substation site options not previously identified.  Because this is a new addition to the original proposal, we would like to hear from you about this project development.
