Relicensing Overview

SCE’s operating license for the Rush Creek Project (Project), FERC Project No. 1389, expires on January 31, 2027. Consequently, SCE is taking the initial steps required by the Federal Power Act and the Federal Energy Regulatory Commission (FERC) to obtain a new license for the Project using the Integrated Licensing Process (ILP). The ILP requires that SCE prepare a Notice of Intent (NOI) and Pre-Application Document (PAD) to be filed with FERC between five and five and one-half years before the expiration of the existing license (i.e., January 31, 2022).

Existing Project Description

The Rush Creek Project is located on the eastern slope of the Sierra Nevada Mountains in Mono County, California. The Project is situated approximately four miles southwest of the unincorporated community of June Lake. The majority of the Project occupies federal lands within the Inyo National Forest which is under the jurisdiction of the U.S. Forest Service (portions of the Project are located within the Ansel Adams Wilderness Area). The Project was constructed between 1915 and 1918 and later modified in 1924 and 1925, prior to the formation of the Wilderness.

The 13.01-megawatt Project includes three dams and associated reservoirs – Agnew Dam (Agnew Lake), Gem Dam (Gem Lake), and Rush Meadows Dam (Waugh Lake); a water conveyance system; the Rush Creek Powerhouse; and ancillary facilities. The three Project reservoirs historically provided storage for lake recreation during the summer and allowed for electricity generation at the Rush Creek Powerhouse in the fall/winter. Water exiting the powerhouse enters a short tailrace and is returned to Rush Creek upstream of Silver Lake.

Recently, SCE conducted fault studies, structural testing, and engineering analyses of Agnew, Gem, and Rush Meadows dams as a consequence of the Silver Lake Fault being identified as a potential safety concern in 2007. As a result of the analyses and subsequent consultation with FERC and DSOD, SCE implemented storage restrictions at the three reservoirs beginning in 2012, as well as structural modifications at Agnew and Rush Meadows dams in 2017 and 2018 and Gem Dam in 2020 and 2021.

Upcoming Public Meetings

There are no upcoming meetings at this time.

SCE invites all stakeholders to attend a webinar (Microsoft Teams Meeting) on January 20, 2022 from 9-11 am. The purpose of the webinar is to discuss (1) 2022 FERC relicensing milestones; (2) PAD content and organization, including Draft Technical Study Plans (TSP); and (3) the process for enhanced Stakeholder collaboration to review and discuss Draft TSPs, including establishment of future Technical Working Group (TWG) meetings.

Technical Working Groups (TWG)

The TWG process is open to all interested parties including public agencies, Native American tribes, and non-governmental organizations, as well as individuals. Participants are expected to make a significant time commitment to prepare for and attend meetings, review documents, and provide technical input to SCE and its consultants on methods, analysis, and interpretation in a timely fashion. In light of this time commitment, it is expected that the TWG process will attract a relatively small number of subject matter experts. SCE will also support a concurrent but separate outreach effort to provide information about the relicensing to the interested public as well as stakeholders electing not to participate in the TWG process via electronic communication and updates to the Project website.

Meetings with TWGs will be held in the winter and spring 2024 to discuss the first round of Technical Study Reports. Prior meetings with TWGs were held in February and March 2022 to solicit input on development of Technical Study Plans. 

To be included in the TWG process, please complete the Technical Working Group Sign-up Form
