Mountain States Transmission Intertie (MSTI)
NorthWestern Energy (NorthWestern), 40 East Broadway, Butte, MT 59701, has
submitted a Montana Major Facility Siting Act (MSFA) application to the Montana
Department of Environmental Quality (DEQ) to construct a 500 kV electric
transmission line. NorthWestern proposes to construct, operate, and
maintain the line from Montana to Idaho. As proposed, the line would
extend from a new substation approximately 5 miles south of Townsend, MT
through the Whitehall and Butte areas to an enlarged Mill Creek substation east
of Anaconda and then south along the Interstate 15 corridor in Montana to the
Midpoint Substation in south central Idaho.
