NEPA Process

For the B2H Project, the U.S. Bureau of Land Management (BLM) is the lead federal agency responsible for NEPA compliance. The process began when Idaho Power submitted applications to the BLM and the U.S. Forest Service (USFS) to construct the transmission line across portions of federally-managed lands.

BLM and USFS initially launched the NEPA process with scoping meetings and a comment period in fall 2008. Comments received during the public scoping period were included in the Public Scoping Report. Following scoping, Idaho Power developed a new proposed route and alternative routes based on public input from its Community Advisory Process (CAP).

In summer 2010, Idaho Power submitted new routes and related documents to the federal agencies. The federal agencies re-opened scoping on Idaho Power’s revised proposed route in July 2010 and conducted additional public scoping meetings in August 2010. BLM compiled the comments received in 2010 and 2008, as well as those submitted through Idaho Power's CAP, and summarized them in the revised scoping report.

BLM took into consideration information from cooperating agencies, the public and Tribes to help identify issue areas and a range of reasonable alternatives for analysis, which are documented in the Final EIS. The BLM used the analysis in the Final EIS to issue its Record of Decision (ROD) for the project on Nov. 17, 2017. The ROD allows the granting of a right-of-way to Idaho Power Company for the construction, operation, and maintenance of the B2H Project on BLM-administered land. The selected route approved by the decision is the Agency Preferred Alternative identified in the Final EIS and Proposed Land-use Plan Amendments

This image shows the National Environmental Policy Act process. The process begins with the Notice of Intent which initiates public scoping meetings and a 60-day comment period. A draft environmental impact statement (DEIS) will be published and is followed by public meetings and a minimum 90-day comment period. A final environmental impact statement will be published, which includes the agencies’ response to comments on the draft environmental impact statement, and is immediately followed by a 30-day notice.

Next Steps

BLM to issue right-of-way grant to Idaho Power

BLM expects to issue a right-of-way grant to Idaho Power in fall 2017. The right-of-way authorization will allow Idaho Power to construct, operate and maintain the transmission line on BLM administered land.

USFS draft ROD

The USFS will issue a separate ROD for the project on the basis of the analysis in the Final EIS. Please see the USFS page for more information.
