FERC Issues Formal Notice for Pacific Gas and Electric Company's Mokelumne River Project

Strategic Insights -

The Federal Energy Regulatory Commission (FERC) has issued a formal notice regarding the Pacific Gas and Electric Company's (PG&E) application for a license amendment of the Mokelumne River Project No. 137. The notice, dated June 17, 2025, announces the availability of an Environmental Assessment (EA) for the project, which includes the construction of a new spillway at the Tiger Creek regulator dam and the decommissioning and abandonment of the existing spillway.

The Mokelumne River Hydroelectric Project, located in Alpine, Almador, and Calaveras counties, California, occupies federal land administered by the U.S. Bureau of Land Management and land within the Eldorado, Stanislaus, and Humboldt-Toiyabe national forests administered by the U.S. Forest Service. The EA concludes that the proposed amendment, with appropriate environmental protective measures, would not constitute a major federal action that would significantly affect the quality of the human environment.
