SUPPLEMENTARY INFORMATION:

Background—The NRCS and Utah Department of Agriculture and Food (UDAF) are analyzing alternatives to rehabilitate the Green River/Tusher Diversion Dam due to damage from the late 2010 and early 2011 flood events. The dam was constructed in the early 1900's and has been modified over the years to maintain the structure. During the 2010/2011 flood events, flows in the Green River caused severe damage to the diversion structure compromising its structural integrity. If the dam fails, water delivery to two irrigation canals, a historic irrigation water wheel delivery system, and one hydropower plant would be eliminated.

The rehabilitation of the diversion dam would be funded through the NRCS Emergency Watershed Protection (EWP) program (CFR, Title 7: Agriculture, Part 624—Emergency Watershed Protection) via technical assistance and partial construction funding. A National Environmental Policy Act (NEPA) Programmatic EIS was prepared by NRCS for the overall EWP program in 2004; however, the rehabilitation of this diversion dam does not fit within the analysis parameters of the Programmatic EIS. Therefore, additional NEPA analysis is required for this project.

The project started out under the analysis of an Environmental Assessment (EA) during the first scoping period that was opened from October 30, 2012 to November 30, 2012. A public scoping meeting was held on November 15, 2012 at Green River City Hall in Green River, Utah. Through additional consultation with the Utah State Historic Preservation Office (SHPO) under Section 106 of the National Historic Preservation Act, it was determined that the diversion dam may be eligible for listing on the National Register of Historic Places. Any modifications to the dam may be considered an “adverse effect” which may make it ineligible for listing after rehabilitation. A wide range of alternatives is being considered for the project as listed in the Alternatives section below. Some of the impacts to the diversion dam from these alternatives may be considered “significant” to cultural resources and as a result, NRCS has decided to prepare an EIS for the project. The EIS will be prepared consistent with Title 390, The National Emergency Watershed Protection Program Manual.

The Upper Colorado Endangered Fish Recovery Program (Recovery Program) is proposing to fund and install a fish barrier in the west irrigation and hydropower plant canal to prevent Endangered Species Act (ESA) listed fish species from entering the canal and/or hydropower plant. As part of the dam repair, upstream and downstream fish passage may also be incorporated into the design. These fish protection and passage components are proposed for inclusion in the Green River diversion rehabilitation project to help reduce mortality of ESA listed fish species populations in the Green River.

Scoping Process—NRCS invites all interested individuals and organizations, public agencies, and Native American Tribes to comment on the scope of the EIS, including the project's purpose and need, alternatives proposed to date, new alternatives that should be considered, specific areas of study that might be needed, and evaluation methods to be used.

Background information including the project purpose and need and alternatives developed to date will be available prior to the scoping meeting on the NRCS Utah EWP Web site (http://www.ut.nrcs.usda.gov/​programs/​EWP/​index.html). Electronic and hard copies of supporting documentation are also available from Mr. Greg Allington, McMillen, LLC, (208) 342-4214 or greg.allington@mcmillen-llc.com.

Once the scope of the EIS is confirmed upon the close of scoping, NRCS will begin preparation of the draft EIS. A summary of comments received during the scoping period will be compiled in a scoping report which will be available on the NRCS Utah EWP Web site.

Project Study Area and Environmental Setting—The proposed project is located approximately 6.6 miles north of the city of Green River in Emery/Grand Counties, Utah. The project study area includes land that is unincorporated on both sides of the Green River. The primary study area includes the diversion dam where rehabilitation activities would occur. Secondary study areas include areas required for alternatives of the project as described in the Alternatives section below such as the powerhouse raceway, irrigation canal on the east side of the diversion dam, construction staging areas on both sides of the river, and potential impacts to the river and riparian area upstream of the diversion dam.

The environmental setting for the project area is primarily located in a riverine environment surrounded by a relatively narrow riparian plant Start Printed Page 33051community adjacent to the river. Beyond the riparian community are agricultural fields on the east side of the diversion dam and BLM land on the west side of the diversion dam that is primarily comprised of desert shrubs and grasses.

Environmental resources consist of the natural and man-made environment. Preliminary resource concerns associated with the rehabilitation of the diversion dam may include both beneficial and negative impacts to water quality and supply, fish, threatened and endangered species, cultural, recreation, aesthetics, and public health and safety.

Alternatives—NRCS is analyzing the following conceptual alternatives to rehabilitate the diversion dam:

  • Repair Existing Diversion Dam: Repair the existing diversion to safely pass flood events.
  • Replace Existing Diversion Dam: Demolish the existing diversion dam and install a new dam in the same location.
  • Replace Diversion Dam Downstream: Demolish the existing diversion dam and install a new diversion dam downstream.
  • Replace Diversion Dam Upstream: Demolish the existing diversion dam and install a new diversion dam upstream.
  • Diversion Decommissioning: Completely remove the diversion dam from the river and stabilize the diversion site. The existing water rights at the dam would be supplemented via pumping out of the river or other options to provide water to the water rights holders.
  • Fish Passage Upstream/Downstream: Construct a passage system(s) on the dam to allow safe upstream and downstream passage of fish over the diversion dam.
  • Electric Fish Barrier: Install an electric fish barrier to prevent fish from swimming into the powerhouse and irrigation canal on the west side of the diversion dam.
  • Fish Barrier: Install a fish barrier to prevent fish from swimming into irrigation canal on the east side of the diversion dam.
  • Boat Passage Upstream/Downstream: Construct a passage system(s) on the dam to allow safe downstream passage of boats past the diversion dam.

NRCS will consider any viable alternatives brought forward during scoping if it is substantially different from the alternatives described above. NRCS will also study a No-Action alternative which would consist of no Federal money used for the rehabilitation of the diversion dam.

Cooperating Agencies—Federal, state, and local agencies that may be interested in or affected by the project may request or be requested by NRCS to become a cooperating agency in the development of the EIS.
