The Utah Board of Water Resources on Jan. 23 told the Federal Energy Regulatory Commission that it plans to file a preliminary license propsal this summer on a 345-MW hydro project.
On May 14, 2014, FERC had granted the board a two-year extension of its preliminary permit allowing it to continue to study the feasibility of the proposed project, which isto be located between Lake Powell on the Colorado River and Sand Hollow Reservoir, through Kane and Washington counties, Utah and through Coconino and Mohave counties, Arizona. The board said in the Jan. 23 update that it plans to file the preliminary licensing proposal in July 2015, and then prepare and file the license application in the July 2015-January 2016 period.
The board said its work over the next six months will include: complete the updated final Water Needs Assessment, Socioeconomics and Water Resource Economics, Land Use Plans and Conflicts, and other associated study reports; incorporate the Bureau of Reclamation’s updated model results into the Surface Water Resources, Surface Water Quality, and Socioeconomics final study reports; complete the Final Draft Class III Report incorporating all Bureau of Land Management and Department of the Interior comments; provide further study results to agencies for review and comment; coordinate with the agencies on mitigation measures; complete the preliminary draft biological assessment; and complete final study reports for all disciplines.
The project would consist of: building and operating 139 miles of 69-inch-diameter pipeline and penstock, 35 miles of 48- to 30-inch-diameter pipeline, and six miles of 24-inch-diameter pipeline; a combined conventional peaking and pumped storage hydro station; five conventional in-pipeline hydro stations; and transmission lines.
