In accordance with the National Environmental Policy Act of 1969, as amended, and the Federal Energy Regulatory Commission's (Commission) regulations (18 CFR Part 380), Commission staff has reviewed plans, filed May 13, 2008, and supplemented April 17, 2009, to perform seismic remediation work at Crane Valley Dam, part of the Crane Valley Hydroelectric Project. The project occupies approximately 738 acres of federal lands within Sierra National Forest, approximately 40 miles northeast of the city of Fresno in Modesto County, California. Crane Valley Dam is located on North Fork Willow Creek, in the San Joaquin River Basin. An environmental assessment (EA) has been prepared as part of staff's review.
The project licensee, Pacific Gas and Electric Company (PG&E), at the request of the California Department of Water Resources, Division of Safety of Dams (DSOD), revised the seismic stability analyses for Crane Valley Dam, finding that modifications to the dam are necessary to correct a possible vulnerability during a seismic event that could lead to an uncontrolled release, endangering downstream residents. Accordingly, the Commission has required remediation under Part 12 of its regulations.
PG&E proposes to increase the seismic stability of Crane Valley Dam by: (1) Adding approximately 200,000 cubic yards of rock fill to areas on the upstream and downstream faces of the dam; and (2) raising the elevation of the dam by approximately 10 feet, to increase freeboard, using approximately 10,000 cubic yards of earth fill. Consultation among the Commission, DSOD, and the licensee has also determined that Bass Lake's normal recreational elevation should be reduced 10 feet in 2009 and 2010 to reduce pressure on the dam until the remediation work is complete. The proposed work would be performed within the project boundary and on U.S. Forest Service lands.
In the EA, Commission staff analyzes the probable environmental effects of the proposed work and has concluded that approval of the work, with appropriate environmental measures, would not constitute a major Federal action significantly affecting the quality of the human environment.
