Bureau of Reclamation December 18, 2024 – Federal Register Recent Federal Regulation Documents

In 2020, the U.S. Army Corps of Engineers (Corps), Bureau of Reclamation (Reclamation), and Bonneville Power Administration (Bonneville) issued the 2020 Columbia River System Operations Final Environmental Impact Statement (CRSO EIS; DOE/EIS-0529), which addressed the ongoing operations, maintenance, and configuration of fourteen Federal Columbia River System (CRS) multiple purpose dams and related facilities located throughout the Columbia River basin. The Corps and Reclamation (Co-Lead Agencies) intend to prepare a supplemental EIS to address environmental effects from proposed changes to the selected alternative in the CRSO EIS and new circumstances and information about the significance of adverse effects that arose or became available after completion of the CRSO EIS. Bonneville has not elected to serve as a co-lead agency for this SEIS and has instead expressed interest in participating as a cooperating agency.
