Regulatory Process and Stakeholder Engagement
Southern California Edison (SCE) has been engaged for over two decades in the regulatory process to renew its seven Big Creek System Federal Energy Regulatory Commission (FERC) project licenses. This has entailed a significant effort to assess each project's potential impact on the environment, its benefits, and consult with a broad spectrum of stakeholders to identify measures to mitigate these impacts and enhance benefits. SCE has worked collaboratively with stakeholders to produce a "package" of agreements that balance resource protection while maintaining reliable hydropower to its customers.
Since the issuance of the Big Creek No. 4 Hydroelectric Project license in December 2003, SCE has implemented various resource management plans, and most recently finalized the Long-Term Operating Rules (LTOR) for river flows in the Horseshoe Bend Reach of the San Joaquin River.
The remaining six Big Creek Projects are still pending issuance of their new FERC licenses, and are currently operating under annual renewals. As part of the FERC relicensing proceedings, stakeholders actively participated in the negotiation and development of potential mitigation measures, culminating with stakeholders signing the Settlement Agreement (or “Agreement”) in February 2007. This Agreement serves as the basis for regulatory assessment and decision-making and has the support of SCE, FERC, key Agencies, and a broad cross-section of public stakeholders. A link to the Settlement Agreement is provided below (Settlement Agreement).
State Water Board: 401 Water Quality Certification and California Environmental Quality Act (CEQA)
On June 17, 2019, SCE filed a Petition for Declaratory Order (“Petition”) with FERC to declare that the California State Water Board has waived authority under Section 401 of the Clean Water Act (“CWA”) for lack of issuance of the water quality certification (“WQC”) within the statutorily prescribed one-year time period for the six Big Creek Projects.
FERC granted SCE’s petition to waive the California State Water Control Board’s water quality certification authority with respect to the relicensing of the six Big Creek Projects on February 20, 2020.
The Final CEQA Supplement for the 6 Big Creek Projects was issued on May 13, 2019. For additional documents related to the CEQA Supplement and the Water Quality Certification, refer to the California State Water Board website, accessed here.
