Floodplain/Wetland Involvement at the Supply Creek Crossing for the Granby Pumping Plant-Marys Lake 69-Kilovolt Transmission Line, Grand County, Colorado

Résumé

Western Area Power Administration (Western), a power marketing agency of the U.S. Department of Energy (DOE), is the lead Federal agency for a proposal to reroute a 0.8 mile section of the Granby Pumping Plant-Marys Lake 69-kilovolt (kV) transmission line, located in Grand County, Colorado, approximately 10 miles north of the Town of Granby. Western plans to remove eight wood-pole H-frame structures from the existing right-of-way and relocate them farther to the west, a distance ranging from a few hundred feet to approximately 1,000 feet. All the proposed work will likely occur within a 100-year floodplain of Supply Creek.

The landowner has requested that Western relocate this section of line to facilitate his ongoing ranching operations. Access to this section of transmission line for maintenance is difficult due to hay meadow irrigation and naturally occurring wet conditions. Relocation of the line will reduce the number of transmission line structures presently located within the wetland area. In accordance with the DOE's Floodplain/Wetland R
