Pacific Gas and Electric Company (PG&E) has received approval from the Federal Energy Regulatory Commission (FERC) to proceed with repairs to the Scott Dam spillway.

The repairs are part of the Potter Valley Project, FERC No. 77, and are intended to address deficiencies in the spillway concrete. The project requires PG&E to address several comments and requests from FERC, including improving the quality and content of resumes submitted as a requirement for a QCIP, providing details for scaffolding to be used, and coordinating any additional areas of repairs with FERC prior to proceeding.

To ensure the project is completed safely and in accordance with FERC regulations, PG&E is required to submit several documents within 90 days of completion, including a final construction report, construction certifications, and revised exhibits. The final construction report must include a summary of information pertinent to dam safety, while the construction certifications must verify that the project was constructed in accordance with the design intent and in accordance with the plans and specifications reviewed by the Commission.
