Plan filed for largest dam removal project in the US

5 July 2018

The Klamath River Renewal Corporation (KRRC) has filed a plan for the removal of four dams on the Klamath River with the Federal Regulatory Energy Commission (FERC), representing a major step in the organization’s plan to restore the river in what has been described as currently the largest dam removal project in US history.

The “Definite Plan for the Lower Klamath Project” provides substantive and specific details for the proposed removal of the J.C. Boyle, Copco No. 1, Copco No. 2, and Iron Gate dams.  It was filed on June 28 2018 as part of KRRC’s application to FERC for the transfer of the FERC license to operate the dams.

FERC will now review the Definite Plan to confirm KRRC has the technical, legal, and fiscal capacities to become the licensee. KRRC’s dam removal and river restoration project is expected to improve water quality, revive fisheries, create local jobs, and boost tourism and recreation.

The Definite Plan is an approximately 2,300-page document that provides comprehensive analysis and detail on project design, deconstruction, reservoir restoration, and other postdeconstruction activities. KRRC also filed responses to FERC’s requests for additional information, including requests in FERC’s March 15, 2018 order, as a part of its regulatory review and approval process.

Among the many topics covered in the Definite Plan are KRRC’s plans to: manage construction impacts, manage impacts to groundwater wells, perform flood-proofing, improve roads and bridges, provide recreation opportunities, replace the City of Yreka water line, protect aquatic resources, and provide for ongoing fish hatchery operations. The plan also provides updated information on project costs and risk management.

 “We have completed a major milestone through the development and filing of this plan,” said KRRC Executive Director, Mark Bransom. “KRRC has developed this plan with tremendous respect for the complexity of the project and with extraordinary care in its efforts to enhance benefits and minimize impacts to local communities. I am proud of this achievement and I look forward to the next steps in the regulatory review process.”

In May, FERC authorized KRRC to convene a panel of nationally recognized experts to serve as an Independent Board of Consultants (BOC) for the project. This panel brings expertise in dam construction and removal, engineering, aquatic and terrestrial biology, construction cost estimating, and risk management.

During the coming months, FERC and the BOC will review and provide guidance on the Definite Plan. KRRC said it welcomes this feedback and will continue its planning and preparations in anticipation of a future decision by FERC on the transfer and surrender applications.

If KRRC receives all necessary approvals to begin work, it expects to begin site preparations in mid-2020, with dam removal and restoration activities commencing in 2021.
