Hungry Horse Powerplant Modification

The Bureau of Reclamation issued the final Environmental Assessment (EA) and Finding of No Significant Impact (FONSI) for the proposed Hungry Horse Powerplant Modernization and Overhaul Project.

The 10-year project involves modernizing and overhauling the powerplant to provide electrical power generation for an additional 30 years, while maintaining operations for flood risk management and fisheries resources. Many of the powerplant’s principal components have reached or exceeded their intended service life. They show problems stemming from age related wear that could potentially result in increased failures and longer forced outages, more-challenging repairs due to obsolescence and lack of spare parts, and higher operation and maintenance costs.

In order to meet current industry and life-safety standards, Reclamation would install new fire prevention and protection safety features; inspect and repair powerplant elevators; and replace or repair five of the six overhead cranes.

The final EA and FONSI were prepared in accordance with the National Environmental Policy Act.
