City of Shasta Lake Initial Study
January 16, 2015

City of Shasta Lake Initial-StudyThis Initial Study has been prepared by AES and the City of Shasta Lake in accordance with the California Environmental Quality Act (CEQA) to examine the potential environmental effects associated with construction and operation of the proposed Wastewater Treatment Facility (WWTF) Upgrade Project. The Proposed Project consists of various upgrades to the existing WWTF that are required to treat raw wastewater to a level that is compliant with the 2014 National Pollutant Discharge Elimination System (NPDES) Permit. The Proposed Project includes a new effluent discharge pipeline, cascade re‐aeration structure, and replacement of the primary outfall into Churn Creek (discharge point 001). The secondary outfall into Churn Creek (discharge point 002) would be abandoned in place. Additionally, the spray fields and 400-acre-foot reclaimed water reservoir would be taken off line and abandoned in place. With the exception of the improvements to the effluent pipeline and outfall structure in the riparian area of Churn Creek, the majority of proposed improvements would take place within the existing development footprint of the WWTF. Supporting technical documents prepared by AES included as appendices to the Initial Study include: Biological Resources Assessment, Biological Assessment and Essential Fish Habitat Assessment, Wetland Delineation Report, California Red Legged Frog Site Assessment, and Arborist Report.
