Big Sulphur Creek – III Water Extraction Facility Replacement Project On September 28, 2022, Calpine Corporation filed a water quality certification application for the Big Sulphur Creek – III Water Extraction Facility Replacement Project (Project). The Project involves replacing a surface water intake facility on Big Sulphur Creek in the Geysers Geothermal Steam Field in Sonoma County, California. The project is limited to removal and replacement of an existing water diversion system which draws water from Big Sulphur Creek and provides injection water as part of Calpine’s geothermal operation at the Geysers. The current diversion includes a screened intake that hangs from a bridge and is lowered into the channel as needed to divert water. Two pumps sit on the channel bank that pump the diverted water approximately 100 vertical feet uphill to an injection well. The new diversion system permanently installed in the channel and will include a new screen and pumping and piping system to reduce impacts to multiple aquatic species, the environment, and improve the safety and operations of the diversion. Additionally, rock riprap will be used as part of a bank stabilization effort to facilitate access to the site. 11/01/2022
Meridian Farms Fish Screen Project – Phase 2 On October 3, 2022, (MFWC) filed a water quality certification application for the Meridian Farms Fish Screen Project – Phase 2 (Project).  The Project involves: (1) the removal and replacement of existing infrastructure at both the Meridian and Drexler Service Areas, (2) construction of new diversion structures at both the Meridian and Drexler diversion points, (3) an increase in capacity at the Main Canal to convey flows to the Drexler Service Area, and (4) an extension of the existing Drexler pipeline to convey flows from the Main Canal to the Drexler Service Area. The new diversion structure equipped with the fish screen would increase the diversion capacity to compensate for the abandonment and removal of the Drexler Pumping Plant and reduce fish entrainment in the pumps. 11/01/2022
South State Water Project Hydropower The California Department of Water Resources (DWR) and the Los Angeles Department of Water and Power filed an application with the State Water Resources Control Board (State Water Board) for a water quality certification amendment for the South State Water Project Hydropower (Project).  The amendment would make the following changes: 1) minor language adjustments to Condition 3; 2) modification of ramping rates for downstream water deliveries made to United Water Conservation District; 3) removal of Condition 6, Large Woody Material; and 4) removal of Condition 7, Gravel Enhancement. 04/12/2022
Camp Far West Auxiliary Spillway Project On July 3, 2017, the Federal Energy Regulatory Commission (FERC) issued a letter to South Sutter Water District (SSWD) directing SSWD to increase the Camp Far West Dam spillway’s existing capacity from 106,500 cubic feet per second (cfs) to 134,100 cfs to reduce the risk of dam failure. On February 17, 2022, SSWD filed a water quality certification application associated with its FERC license amendment request for the Camp Far West Auxiliary Spillway Project (Project). The Project consists of constructing a new auxiliary spillway and inlet channel that would be located adjacent to the existing Camp Far West Dam spillway to implement FERC’s directive for additional spillway capacity. The new auxiliary spillway would also require a new bridge on the existing roadway. 03/18/2022
Jeff L. Taylor – Pine Flat Hydroelectric Project The Kings River Conservation District (KRCD) proposes to add a new generating unit to the Jeff L. Taylor Powerhouse that will utilize flows up to 375 cubic feet per second (cfs) released from the United States Army Corps of Engineers’ Pine Flat Lake. The new unit will utilize flows that cannot be used to generate power in the existing powerhouse and are currently discharged through the powerhouse bypass system. This will increase the generating capacity by approximately 6.3 megawatts (MW) from 165 MW to 171.3 MW, an increase in name-plate generation capacity of 3.8 percent and will not increase the existing 8,000 cfs maximum hydraulic capacity of the Project. 01/24/2022
Bear Creek Diversion Dam Replacement Project Demolish the existing Bear Creek Diversion Dam and pipeline and replace with a new dam approximately 100 feet downstream. Reconstruct the intake structure and a portion of the conveyance canal. 05/11/2010
