The SWRCB is <br /> responsible for developing statewide water quality policy and exercises the powers delegated to the state by the <br /> federal government under the CWA. Other state agencies with jurisdiction over water quality regulation in <br /> California include the DHS (for drinking water regulations),the California Department of Pesticide Regulation, <br /> the California Department of Fish and Game(DFG), and the Office of Environmental Health and Hazard <br /> Assessment. <br /> Regional authority for planning,permitting, and enforcement is delegated to the nine RWQCBs. The regional <br /> boards are required to formulate and adopt water quality control plans for all areas in the region and establish <br /> water quality objectives in the plans. The Central Valley RWQCB is responsible for the water bodies in the <br /> project vicinity. <br /> Porter-Cologne Water Quality Control Act <br /> The Porter-Cologne Water Quality Control Act(Porter-Cologne Act)of 1969 is California's statutory authority <br /> for the protection of water quality.Under the act,the state must adopt water quality policies,plans, and objectives <br /> that protect the state's waters for the use and enjoyment of the people. The act sets forth the obligations of the <br /> SWRCB and RWQCBs to adopt and periodically update water quality control plans(also called Basin Plans). <br /> Basin Plans are the regional water quality control plans required by both the CWA and Porter-Cologne Act in <br /> which beneficial uses,water quality objectives, and implementation programs are established for each of the nine <br /> regions in California. The act also requires waste dischargers to notify the RWQCBs of their activities through the <br /> filing of Reports of Waste Discharge(RWD)and authorizes the SWRCB and RWQCBs to issue and enforce <br /> waste discharge requirements (WDRs),NPDES permits, Section 401 water quality certifications, or other <br /> approvals. The RWQCBs also have authority to issue waivers to RWD/WDRs for broad categories of"low <br /> threat"discharge activities that have minimal potential for adverse water quality effects when implemented <br /> according to prescribed terms and conditions. <br /> Water Quality Control Plan for the Sacramento—San Joaquin River Basins <br /> The Water Quality Control Plan for the Sacramento—San Joaquin River Basins (Basin Plan), adopted by the <br /> Central Valley RWQCB in 1998, identifies the beneficial uses of water bodies and provides water quality <br /> objectives and standards for surface waters and groundwaters of the Sacramento River and San Joaquin River <br /> basins, including the Delta. State and federal laws mandate the protection of designated"beneficial uses"of water <br /> bodies. State law defines beneficial uses as"domestic; municipal; agricultural and industrial supply;power <br /> DER EDAW <br /> City of Manteca 4.9-17 Hydrology and Water Quality <br />
