Hells Canyon

Hydropower Relicensing (Idaho)

As part of a nationwide contract with the Federal Energy Regulatory Commission (FERC), The Louis Berger Group, Inc. (Berger) was retained to represent FERC for some aspects of the relicensing procedure for three hydroelectric developments on the Snake River on the Idaho-Oregon border.  The three Idaho Power developmentsBrownlee, Oxbow and Hells Canyoncomprise the Hells Canyon Project (FERC No. 1971).  The license for the Hells Canyon Project expired in July 2005.

Berger and its subconsultants have supported FERC in two phases of the project:

Phase 1—Pre-application Public Involvement

The relicensing effort followed the Traditional Licensing Process (TLP), except that it also included a structured public involvement process in the early stages of preparing the license application.  A group of agencies, tribes, conservation groups, customers, and others worked together to frame public issues, resolve controversies, and involve interested parties to help ensure that the application would address relevant stakeholder needs.  During the public process, Berger and its subconsultants represented FERC at collaborative team meetings and in three working groups, including aquatic resources, terrestrial resources, and recreation.   The working groups developed protection, mitigation, and enhancement recommendations that were considered by Idaho Power and, in some cases, included in the license application.  Berger staff filled FERC lead roles for the water quality and geomorphology tasks under the Aquatics Work Group. 

As part of Berger’s efforts to develop early familiarity with this complex project on behalf of FERC, Berger staff participated on the Public Advisory Team involved in developing the Total Maximum Daily Load (TMDL) for the Hells Canyon portion of the Snake River.  Staff provided summary reports to FERC on the progress of the TMDL and focused on hydroelectric related impacts on water quality in the basin. Because the Brownlee development includes a large storage reservoir, effects were considered on a variety of parameters including temperature, dissolved oxygen, and sediment.  EPA provided comments on the TMDL and a revised TMDL was submitted to EPA.

Phase 2—Preparation of the Environmental Impact Statement

Subsequent to Idaho Power’s submittal of its license application, the Berger Team has participated in scoping meetings; identified issues to be addressed in the environmental impact statement (EIS), prepared Scoping Documents 1 and 2, performed an adequacy review of the license application, prepared Additional Information Requests that required Idaho Power to perform additional studies to provide information necessary to support environmental evaluation of the license application, prepared the draft EIS that was released in August 2006, participated in public meetings held to elicit public comments on the draft EIS, and participated in meetings with state and federal fish and wildlife agencies to discuss issues subject to the agencies’ authorities under the Federal Power Act and the Endangered Species Act. Berger prepared the final EIS, including responses to comments on the draft EIS, which was issued on August 31, 2007.  Major issues addressed in the EIS include water quality parameters, especially temperature, dissolved oxygen, and total dissolved gas; sediment transport and deposition; anadromous fish conditions; wildlife habitat; and cultural and recreational resources. In addition to evaluating Idaho Power’s proposed operations and proposed environmental protection, mitigation, and enhancement measures in the EIS, Berger evaluated operating regimes and environmental measures recommended by agencies, tribes, and other parties, as well as concepts developed by Berger and FERC staff.
