4 REQUIRED APPROVALS AND PERMITS Implementation of the project would require approval by the Manteca City Council as the Lead Agency. Other permitting agencies with permitting approval or review authority over portions of the project may include: ► Regional Water Quality Control Board(RWQCB)—National Pollutant Discharge Elimination System (NPDES)General Construction Stormwater Permit, General Order for Dewatering,NPDES Waste Discharge Permit. ► San Joaquin Valley Air Pollution Control District—Authority to Construct and Permit to Operate. ► California Department of Health Services rules concerning the use of wastewater effluent for urban irrigation purposes. 5 POTENTIAL ENVIRONMENTAL EFFECTS Proposed wastewater treatment facility construction would occur within the existing WQCF boundaries,while construction of new trunk sewers would occur in several areas throughout the City primarily within existing roadway alignments. The proposed 48-inch effluent outfall would be constructed alongside the existing outfall in the east bank of the San Joaquin River. The EIR will identify and describe the potential environmental impacts associated with implementation of the proposed project. Mitigation measures will be recommended where appropriate to reduce potentially significant and significant impacts. The following issues are proposed for analysis. 5.1 AESTHETICS The proposed project would increase the size of the existing WQCF and involve the construction of pipelines and pump stations in area roadways. The potential visual impacts from construction of new wastewater treatment facilities and trunk sewers, and operation of the proposed wastewater treatment plant will be evaluated through the use of ground-level site photographs from sensitive viewpoints near the project site. The EIR will evaluate the extent of visibility of the project from surrounding, sensitive,public viewpoints. 5.2 AIR QUALITY The proposed project would involve both construction and operational air quality impacts. The EIR will describe regional and local air quality in the vicinity of the project site and evaluate construction and operational impacts to air quality. The project's estimated air emissions will be quantified and compared to emissions thresholds of the San Joaquin Valley Air Pollution Control District(SJVAPCD). A list of mitigation measures will be prepared for any impacts found to be significant or potentially significant. 5.3 BIOLOGICAL RESOURCES The proposed project has the potential to affect several special status species including Swainson's hawk,valley elderberry longhorn beetle, California tiger salamander, and San Joaquin kit fox. Of particular concern is the impact of effluent discharge on the thermal conditions of the river and corresponding migratory fish patterns. The EIR will assess all potentially significant direct and indirect impacts on biological resources posed by the project. Feasible and practical mitigation measures that would minimize or eliminate potential adverse impacts on biological resources will be recommended, including parameters for protection/enhancement of environmentally sensitive habitat. Increased wastewater discharges also have the potential to affect fisheries resources in the San Joaquin River. The EIR will assess all potentially significant direct and indirect impacts(including thermal City of Manteca WQCF and Collection System Master Plan 2005 Update May 2006 9 Notice of Preparation
