The whole of the action includes authorization to prepare final design for the project, construction, and operation of the project. Based on the preliminary project design and anticipated final design, and because the project construction is a minor alteration limited to construction within SCV Water’s existing facility property, we find construction and operation of this project to be categorically exempt under the provisions of CEQA and the State CEQA Guidelines, specifically State CEQA Guideline sections 15301 (aka Class 1), Minor Alterations to Existing Facilities and 15303 (aka Class 3) for New Construction or Conversion of Small Structures. The Treatment System will consist of 2 tanks (approx. 12' diameter, 17' height), associated cartridge filters, piping, booster pumps, a chloramination disinfection facility housed within an approximate 15 ft by 25 ft open shade structure, along with associated electrical, SCADA, and water quality measuring equipment. The vessels will be loaded with Ion Exchange Resin which will trap the contaminants via adsorption. The treatment system will treat up to 1,200 gpm of instantaneous flow. The treatment is needed since the chemical group PFAS, has begun to be regulated, and these wells have had detections of these chemicals, which has led to our inability to use said wells without treatment. A portion of the facility’s block wall will be reconfigured to enclose additional equipment. The discharge line outfalls are within an existing rap bank approximately 70 feet from the Santa Clara River that is dry most of the time. During normal operations the primary discharge at the site will occur when the wells are started up and the well water is discharged to waste prior to sending water through the treatment and distribution system. For well start-up the pump to waste duration is approximately 2-3 minutes at a rate of 1,200 gallons per minute. At a well-shut down/start up frequency of once per month, the total annual volume of discharge is approximately 28,800 to 43,200 gallons.
