        Idaho Power’s
        Proposed Route

Idaho Power submitted the eastern route alternative as the proposed route in its revised applications to the state and federal agencies. The eastern route alternative was one of three route alternatives developed through the Community Advisory Process (CAP) and reviewed by CAP participants in March 2010.

Following the CAP route selection, Idaho Power:

  • Submitted revised right of way and special use permit applications (SF-299) to BLM and USFS, respectively. Idaho Power submitted its revised SF-299 applications to BLM and USFS in June 2010, which restarted the National Environmental Policy Act (NEPA) review process.
  • Submitted the Notice of Intent to ODOE. Idaho Power submitted its revised Notice of Intent to ODOE in July 2010.
  • Submitted any additional permit applications as necessary.

Idaho Power appreciates the time, effort and thought CAP participants contributed throughout this process.

Review of Route Alternatives (March 2010)

    Idaho Power’s three
    route alternatives

In March 2010, Idaho Power presented three route alternatives to the Project Advisory Teams (PATs) and requested PAT feedback. Idaho Power analyzed the comments it received and used the feedback to help determine which of the three route alternatives to submit as its proposed route for the state and federal environmental review processes.

Comments received by March 25, 2010 are included in the final meeting summaries on the North, Central and South PAT pages.

Comparison of the Route Alternatives

Throughout the Community Advisory Process (CAP), Idaho Power has worked with the PATs to identify community criteria, develop a range of possible routes and recommend proposed routes.

Idaho Power’s three route alternatives were developed based on the PAT members’ recommended routes.

The table below compares the three route alternatives.
