0 <br /> ADDITIONAL INFORMATION REQUIREMENTS <br /> FOR REPORT OF WASTE DISCHARGE <br /> CITY OF RIPON WWTP <br /> Please provide a technical report that presents the following information: <br /> 1. A narrative description of all wastewater conveyance, treatment, and disposal systems currently <br /> existing at the facility. <br /> 2. A narrative description of all planned physical improvements, their purpose, and anticipated <br /> completion dates. If phased build out is planned provide scope and completion dates for each phase. <br /> 3. A process flow diagram, treatment plant site plan, and a scaled map showing the limits of all existing <br /> and proposed effluent disposal areas. <br /> 4. For each pond and other waste containment structure,provide the following information. Discuss <br /> both existing and proposed ponds: <br /> a. Identification (name) and function of the pond; <br /> b. Surface area, depth, and volumetric capacity at two feet of freeboard; <br /> c. Height (relative to surrounding grade), crest width, interior slope, and exterior slope of each berm <br /> or levee; <br /> d. Materials used to construct each berm or levee; <br /> e. Description of engineered liner, if any; <br /> f. Estimated steady state percolation rate for each unlined pond; <br /> g. Depth to shallow groundwater below the planned base of the ponds; <br /> h. Overfilling/overflow prevention features; and <br /> i. Operation and maintenance procedures. <br /> 5. A description of the sources and types of wastewater flowing into the system, design flow rates, and <br /> the design capacity of the system (existing and proposed). Include projected infiltration/inflow rates <br /> and peaking factors used in design calculations. <br /> 6. A description of emergency wastewater storage facilities or other means of preventing system bypass <br /> or failure during reasonably foreseeable overload conditions (e.g., power failure, sewer blockage, and <br /> illicit sewer discharges). Consider both potential problems at the plant and within the community <br /> sewer system. <br /> 7. A description of the community sewer system: materials, age, infiltration/inflow estimate, and lift <br /> station details (type, location, capacity, backup systems, and alann features). <br /> 8. Chemical characterization of influent wastewater quality, including biochemical oxygen demand, <br /> total suspended solids, total dissolved solids, and nitrogenous compounds. Include a discussion of <br /> seasonal variations, if any, and supporting analytical data. <br /> California Environmental Protection Agency <br /> ea Recycled Paper <br /> The energy challenge facing California is real. Every Californian needs to take immediate action to reduce energy consumption. <br /> For a list of simple ways you can reduce demand and cut your energy costs,see our Web-site at http://www.swrcb.ca.gov/mgcb5 <br />
