Pit 1 Hydroelectric Project, Federal Energy Regulatory Commission Project No. 2687 Section 401 Water Quality Certification, Condition 13 - Request for Temporary
PG&E owns and operates the Pit 1 Hydroelectric
Project (Hydroelectric Project) as a peaking operation that generates 65.5 megawatts of energy from the Pit 1 Powerhouse on the Pit River. On March 19, 2003, the Federal Energy Regulatory Commission (FERC) issued a renewed operating license for the Hydroelectric Project. The FERC license incorporates the water quality certification (certification), issued by the State Water Resources Control Board on December 4, 2001, as part of the terms and conditions of the new FERG license. Per Condition 13 of the certification, PG&E is required to release summer flushing flows from the Pit 1 Forebay Dam to control nuisance aquatic vegetation and mosquito production in Fall River Pond. In this instance, the "Project" constitutes the temporary suspension of summer flushing flows required per Condition 13 of the Hydroelectric Project certification. The temporary suspension of summer flushing flows requested by PG&E and supported by the United States Fish and Wildlife Service, is needed to protect the Shasta crayfish, which is listed as endangered under both the California and Federal Endangered Species Acts.
