<br />00154f) <br /> <br />Chapter 2 - Alternatives <br /> <br />facilities (such as a fish ladder). Article 411 of the license reserves the authority for FERC to <br />require the licensee to construct, or provide for the construction, operation, and maintenance of <br />fishways that may be prescribed by the Secretary of the Interior. This No Action scenario <br />assumes no fish ladder is required. <br /> <br />In 1994, FERC granted a 'stay' on development of the hydropower project for several reasons, <br />These included the need to reinitiate consultation with the Service on the effects of the project on <br />the newly listed razorback sucker and recently designated critical habitat upstream from the <br />project. The project has been on hold pending further order by FERC. On June 27, 1996, the <br />licensee filed an application for amendment of the license. <br /> <br />Fish Ladder with Hydropower Plant <br /> <br />Under this alternative for the Price-Stubb passage, Reclamation would construct a ladder around <br />the dam, similar to the U-shaped ladder constructed in 1996 at the Redlands Diversion Dam on <br />the Gunnison River (U.S. Bureau of Reclamation, 1995). This alternative also assumes private <br />development ofthe Jacobson Hydro No.1 Project would proceed, as proposed in the licensee's <br />1996 application to amend the FERC license (FERC, 1996). The licensee proposed to: <br /> <br />. <br /> <br />install 'adjustable' 4-foot-high flashboards on top of the existing dam (instead of fixed <br />flashboards) <br />build a power house next to the Price-Stubb Dam (thus eliminating the power canal and <br />bypass reach) <br />dedicate a property easement to the U.S. for the installation of a fish ladder ". . . that would <br />be fully funded by Reclamation" (i.e., the Recovery Program) <br />"dedicate up to 100 cubic feet per second (ds) of water. , . to be used for the fish ladder, <br />attraction flows, and larval separation" <br />"eliminate public access so disturbances are reduced for fish and personnel at the fish ladder <br />installation" <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />. <br /> <br />Before approving the amendment, FERC is responsible for preparing an Environmental <br />Assessment to comply with NEP A and completing a Section 7 consultation to comply with the <br />Endangered Species Act (ESA). On April 14, 1999, FERC released a Draft Environmental <br />Assessment that contains an analysis of the effects of the construction and operation of the <br />proposed amendments to the project (FERC, 1999). The 25-page assessment also serves as the <br />biological assessment for the Section 7 consultation with the Service. FERC's analysis assumes <br />the Secretary of the Interior has decided to construct and operate a fish ladder. However, their <br />assessment does not address current designs for, nor impacts of, the ladder itself. Therefore, <br />Reclamation has assumed responsibility for complying with NEP A and ESA for the fish ladder <br />aspects of the license amendment. <br /> <br />8 <br />
