Environmental Assessment

 

The Bureau of Land Management (BLM) Colorado Southwest District is seeking public input regarding a proposal by Tri-State Generation and Transmission Association (Tri-State) to upgrade an existing transmission line system across private, state, and federal lands in southwestern Colorado.  Tri-State is proposing to upgrade and rebuild the existing Montrose-Nucla-Cahone transmission line from 115 kilovolts (kV) to 230 kV.

   

The Tri-State Montrose-Nucla-Cahone Transmission Improvement Project area includes about 59 linear miles of public land in the BLM Uncompahgre and Tres Rios field offices and about 46 linear miles of public land in the Grand Mesa, Uncompahgre, and Gunnison and San Juan national forests.  An additional 20 miles of line crosses lands managed by the State of Colorado or private landowners.

As the designated Lead Federal Agency, the BLM Southwest District has determined that an Environmental Assessment (EA) is required before the BLM and U.S. Forest Service (FS) can render separate decisions regarding the proposal.

During public scoping, the BLM will accept input regarding potential project issues, impacts, and alternatives that should be addressed in the EA. 

 

This will be the first of several opportunities for public involvement. The Preliminary EA should be available for public review and comment in early 2015. Submitting comments during either comment period establishes standing for BLM appeals and Forest Service objections.

 

For additional project information, contact BLM NEPA Coordinator Gina Jones by phone at (970) 882-6829 or by email to gmjones@blm.gov.  Additional information about the FS objection process can be obtained by contacting Liz Mauch by phone at (970) 240-5405 or by email to lmauch@fs.fed.us.

 

Public scoping for the project closed Wednesday, June 4. Please continue to monitor this website for additional information on the project progression.
