Plant-Windy Gap Transmission Line Rebuild Project
Western owns and operates a 12-mile, 69‑kV electric
transmission line in Grand County, Colo., that originates at
Windy Gap Substation and terminates at Granby Pumping Plant
Switchyard. The proposed project would rebuild the single
circuit line as a double circuit transmission line and add a
second power transformer.
One circuit would replace the existing 69‑kV line; the
other circuit would be a new 138‑kV line. Granby Pumping Plant
Switchyard would be expanded to accommodate the second line
and power transformer. Windy Gap Substation would be modified
to accommodate the second line.
This is a joint project between Western, Tri-State
Generation and Transmission Association, Inc., Mountain Parks
Electric and the Northern Colorado Water Conservancy District.
Western initially determined it would prepare an Environmental
Assessment for this proposed project in December 2004 and held
public open-house scoping meetings on July 28, 2005, and Nov.
15, 2006. Based on a review of public comments and
issues, Western determined to prepare an Environmental Impact
Statement for the proposed project.
Western is the lead agency on the EIS, the U.S. Forest
Service and U.S. Bureau of Land Management are Federal
cooperating agencies; and Grand County is a cooperating local
The final EIS is available. Western sent about 1,200 mailed
notices to those in the project area, agencies, and other
interested stakeholders. Western will issue a Record of
Decision, but not sooner than 30 days after the date of the
Environmental Protection Agency’s publication date of the
Notice of Availability (NOA). The Environmental Protection
Agency published the NOA and set the end date of the 30-day
waiting period at July 29, 2013.
Comments received on the draft EIS are addressed in
Appendix L and the text in the final EIS was changed if needed
to address the comments. Western’s preferred alternative is
Alternative D, Option 1. Western and the U.S. Forest Service
developed a modification to this alternative along CR 64 that
moves the route discussed in the draft EIS to the west to
respond to comments. The modification to the route moves the
proposed route further away from residences and closer to the
Forest Service campground. The final EIS discusses the
modification and local issues that influenced the
