Xcel Energy had requested an extension of time to submit updates to the Supporting Technical Information Document (STID) for the Trego Hydroelectric Project, FERC No. 2711. The company proposed to update the STID by including the Final Construction Report on work at the Left Embankment Toe Drain and update the Dam Safety Surveillance and Monitoring Plan to include Piezometers TRG-23-2 and TRG-24-1 in the Left Embankment by December 31, 2026.
Readings will continue at the new piezometers, and data will be incorporated in the Dam Safety Surveillance and Monitoring Reports. The extension of time request was granted by the Federal Energy Regulatory Commission.
