impacts) on fisheries and aquatic resources resulting from the proposed project. The impact analysis will focus on evaluating the effects of increased effluent discharge on aquatic life in the San Joaquin River and its tributaries. Mitigation measures to minimize or avoid potential adverse affects will be recommended where appropriate. 5.4 CULTURAL RESOURCES The EIR will include recommendations for the management or treatment of significant and potentially significant archaeological and historical resources, as necessary,with a focus on mitigation measures that may be needed to avoid or substantially lessen potentially significant impacts. 5.5 GEOLOGY, SOILS, AND SEISMICITY The proposed project would require grading,trenching, and other earthwork to upgrade and expand the City's WQCF and wastewater collection system. The EIR will evaluate potential geologic hazards related to soil erosion, strong ground shaking, subsidence, and liquefaction. Recommendations will be made to mitigate significant adverse impacts where feasible. 5.6 HAZARDS AND HAZARDOUS MATERIALS The proposed project could expose humans to hazardous materials or hazardous waste. The analysis presented in the EIR will qualitatively evaluate the potential for human and environmental exposure to any pre-existing hazardous materials/waste in the project area. The EIR will identify mitigation measures to ensure that any significant potential for exposure to hazardous materials/waste is avoided. 5.7 HYDROLOGY AND WATER QUALITY The proposed project would increase treated effluent discharges, and has the potential to adversely affect water quality in the San Joaquin River. The EIR will include a hydrology and water quality impact assessment that is focused on short-term temporary construction-related effects,long-term operations-related water quality impacts, and cumulative onsite and offsite hydrology and water quality impacts. The EIR will analyze impacts related to changes in the water quality of San Joaquin River and downstream surface water bodies caused by proposed changes in treated effluent discharges. 5.8 LAND USE The proposed project would include direct land use effects associated with WQCF and trunk sewer construction, and indirect land use effects of providing wastewater capacity to serve future growth areas of the City. To the degree that analysis of growth-related effects provided in the City's General Plan(2003) and other relevant environmental documents is applicable to the project,it will be summarized in the EIR where appropriate. The compatibility of project facilities with existing and planned land uses will be evaluated. Mitigation measures will be recommended if land use issues contribute to significant physical environmental impacts. 5.9 NOISE The EIR will describe the project's construction and operational noise impacts including noise generated from existing and proposed traffic and will compare these impacts to applicable noise thresholds. 5.10 PUBLIC SERVICES The WQCF and collection system master plan project is a wastewater collection,treatment, and disposal project, and environmental impacts associated with construction of these facilities will be addressed throughout the EIR.
