Hot Springs to Anaconda Transmission Line Rebuild Project (DOE/EIS-0502)
Sanders, Lake, Missoula, Granite, Powell, and Deer Lodge counties, Montana

The Bonneville Power Administration (BPA) proposes to rebuild about 120 miles of existing 230-kiliovolt (kV) wood-pole transmission line that runs through Sanders, Lake, Missoula, Granite, Powell, and Deer Lodge counties, Montana. The 120-mile of line is made up of three BPA transmission lines--the Hot Springs-Rattlesnake, Rattlesnake-Garrison, and Garrison-Anaconda lines. No major work has been done on the lines since they were built in 1952. Rebuilding the deteriorated line would maintain reliable electrical service and avoid risks to the safety of the public and maintenance crews.

The project would include removing and replacing existing wood-pole structures and components, as well as the conductor; improving access roads and establishing temporary access where needed; removing trees adjacent to the line that may cause a threat to reliability; developing staging areas for storage of materials; and revegetating areas disturbed by construction activities. The existing structures would be replaced with structures of similar design within or near to their existing locations. The line would continue to operate at 230 kV.

To understand the potential environmental impacts of this proposal and identify ways to reduce those impacts, BPA will prepare an environmental impact statement (EIS) following the procedures of the National Environmental Policy Act. The EIS will analyze an alternative to rebuild the line, a no action Alternative to not rebuild the line and continue repairing the line on an as-needed basis, as well as any additional viable alternatives brought forward during the scoping process. During this process, BPA will work with federal, state and local agencies, landowners, interest groups, and tribes.

A scoping letter was sent to the public on July 11, 2014 requesting comments on the scope of the project. Public meetings were held in Missoula, Dixon, and Deer Lodge, Montana. The comment period closed August 12, 2014. Comments can be viewed in the Scoping section below.
