Santa Rosa Subregional Water Reclamation System - Incremental Recycled Water Program
Document Type
NOD - Notice of Determination

Document Description
The originally approved project consists of the City of Santa Rosa's Incremental Recycled Water Program (IRWP) to provide for reliable treatment, recycling, and disposal of the wastewater volume from growth anticipated in the General Plans of the communities making up the Sub regional System (Santa Rosa, Rohnert Park, Cotati, and Sebastopol). The IRWP defined and evaluated seven alternatives that include a range of components to achieve the Program's objectives. One of those alternatives included the Geysers Expansion (Alternative 5) located in both Sonoma and Lake counties. The environmental effects of the Geysers Expansion Alternative analyzed up to 25 mgd. The improvements needed for the Geysers Expansion Project included an additional pump at the Llano Pump Station and utilization of an existing redundant fifth pump at the Bear Canyon, Mayacams, and the Pine Flat Pump Stations. Steamfield operations included an additional 3.5 miles of new above-ground pipeline and six new wells to accommodate the additional recycled water flows. The EIR was certified on March 4, 2004. A Subsequent Negative Declaration, under the same title, was later adopted in April 2006, based on the above mentioned certified EIR, for a Use Permit to re-develop existing well pads, drilling up to 58 geothermal wells for steam and injection, constructing up to 29,000 feet of access corridors for steam pipelines, roads, and associated electrical distribution (21kv) at The Geysers. Another Subsequent ND was later adopted in 2007 based on the Geysers expansion Alternative, covered in the IRWP Certified Program EIR. The proposed activity consists of permitting a new geothermal injection well on an existing well pad at The Geysers Geothermal Field in Sonoma County, which is within the scope of the original project(s) described above. This entails minor alteration of land that will not remove any vegetation, nor wil lit create any new roads, buildings or other infrastructure. Additionally, the proposed well site will be a minor alteration of the existing facilities at Calpine's geothermal facility, to assist with production of electric power.
