Williston-to-Tioga Project
Williston-to-Tioga Transmission Project
On May 10, 2010, a Finding of No Significant Impact -- commonly referred to as a FONSI -- was issued by the Western Area Power Administration for a new transmission line that will be constructed in northwest North Dakota. The FONSI was the last regulatory authorization needed before construction could start on the Williston to Tioga transmission line that’s been in the planning stages for the last two years. A FONSI is the result of an environmental assessment that addresses any impacts that may be caused from construction and operation of a project. Construction began on the 61-mile line shortly after the FONSI was issued.
As of Aug. 16, 2010, 96 poles are in place and wires are being strung.
Public hearing
On Aug. 10, 2009, Basin Electric filed an application for a waiver of procedures and time schedules and a consolidated application for a certificate of corridor capatibility and route permit to authorize construction of about 61 miles of 230-kV electric transmission line and associated facilities. The line will extend from an existing substation, owned by Western, near Williston, ND, to an existing substation, owned by Montana-Dakota Utilities, near Tioga, ND. The facilities to be permitted are projected to cost $24 million. A public hearing on the application for a waiver and consolidated application for transmission line corridor and route was held Oct. 27, 2009, at the Commission Hearing Room in Williston, ND. According to Duey Marthaller, Williston-to-Tioga project manager, Basin Electric transmission studies identified a need for additional transmission capacity in the Northwestern part of the state.

An Environmental Assessment is also being prepared by Western Area Power Administration.
