2.0 ENVIRONMENTAL CHECKLIST SETTING OVERVIEW During construction, standard erosion control techniques shall be implemented to reduce any impacts to less-than-significant levels (Measure WQ-1). Project operation would be conducted in accordance with all applicable federal and state requirements. Use of disinfected secondary-23 and disinfected tertiary recycled water would reduce pumping of the local aquifer; consequently potential project impacts to groundwater aze considered beneficial. Project implementation would not affect any watezways designated as Wild and Scenic. Installation of the proposed pipelines and associated facilities would not substantially alter the drainage patterns in the Project vicinity because of the relatively small amount of impermeable surfaces that would be installed. No impacts on downstream flood conditions are anticipated. DISCUSSION a) Operation /Water Reuse. Operation of the proposed water recycling Project would be conducted in accordance with all applicable federal and state requirements. The major federal legislation governing the water quality aspects of the proposed Project is the Clean Water Act, as amended by the Water Quality Act of 1987. The State of California's Porter-Cologne Water Quality Act (Division 7 of the California Water Code) provides the basis for water quality regulation within California. The State Water Resources Control Board (SWRCB) administers water rights, water pollution control, and water quality functions throughout the state, while the Regional Water Quality Control Board (RWQCB) conducts planning, permitting, and enforcement activities. The Porter-Cologne Water Quality Control Act designates the SWRCB responsible for formulating and adopting state policy for water reclamation, while the California Department of Health Services (DHS) is responsible for establishing uniform statewide reclamation criteria to ensure that the use of recycled water would not be detrimental to public health.. There are no federal standards governing wastewater reclamation and reuse in the United States, although the U.S. Environmental Protection Agency has sponsored the preparation of Guidelines far Water Reuse (Camp Dresser & McKee, 1992). Many states, including California, have developed wastewater reclamation regulations. In all cases, the regulations have been established with the objective of protecting public health and allowing for the safe use of recycled effluent. The DHS established water quality criteria, treatment process requirements, and treatment reliability criteria for reclamation operations, which are set forth in Title 22, Division 4, Chapter 3, of the California Cade of Regulations (CCR) Water Recycling Criteria. The RWQCB has responsibility for reviewing proposed recycled water projects, and for issuing water recycling requirements through the RWQCB's permitting process. California DHS is responsible for reviewing water recycling projects, and for providing comments and/or recommendations to the RWQCB. The existing Water Recycling Criteria address treatment requirements for three main types of recycled water uses: Landscape Irrigation, Recreational Impoundments, and Industrial Uses. The treatment requirements are based on the expected degree of human contact with recycled effluent undez each type of use. Treatment requirements are expressed as treatment process requirements (e.g., bio-oxidation, coagulation) as well as performance standards (e.g., disinfection standards and contaminant reduction). The existing Title 22 standards aze among the most stringent standards in the world for public health protection, and are about 100 times more stringent than comparable standards established by the World Health Organization. -Since the adoption of Title 22 in 1978, the use of recycled water for non-potable uses has expanded throughout the state and is projected to continue to grow San Leandro Recycled Water Project 2.-3~ FSA / 7A3193 Dtah IS/MND
