ADDITIONAL INFORMATION REQUIREMENTS • 3 <br /> CITY OF LATHROP WASTEWATER PLANT NO. 2 <br /> LATHROP, SANJOAQUIN COUNTY <br /> f. Provide a land application area description, including at least the following information: <br /> i. Scaled plans showing the limits of all proposed land application areas, including their <br /> relationship to storm drains and surface waters; <br /> ii. For each discrete irrigation area, specify the following: <br /> t. total available area; <br /> 2. net available area(considering setbacks required per 22 CCR, Division 4 water <br /> reclamation regulations); <br /> 3. type of irrigation systems planned, discuss alternative means of wastewater <br /> application (other than sprinkler application). The WDRs will prohibit spray <br /> application when wind velocity exceeds 30 mph; <br /> 4. selected crops, agronomic nutrient rates, and water application rates; <br /> s. tailwater control and return to the storage pond; <br /> 6. public access control. <br /> g. Provide calculations of BOD loading and total nitrogen loading in land application areas. <br /> Maximum allowable BOD loading will be 300 lbs/ac-day (maximum) and 100 lbs/ac-day <br /> (seven-day average). Cropping activities must be sufficient to take up all the nitrogen applied, <br /> assume all nitrogen applied is plant available nitrogen; <br /> h. Submit a conceptual cropping plan which describes available acreage, crop type, crop water <br /> usage, cutting, harvest and removal for complete crop uptake of all applied nitrogen. <br /> Wastewater application shall be performed at agronomic rates; <br /> i. Provide an evaluation of total dissolved solids (TDS) concentrations in the wastewater and an <br /> evaluation of the TDS concentrations in the land application area percolate. Compare the <br /> estimated percolate concentration to the groundwater quality. Will the percolate increase the <br /> groundwater TDS concentration? <br /> j. Means and methods to control public access and/or provide legally required notice regarding <br /> exposure to treated effluent. <br /> 8. Narrative description of proposed solids treatment, storage, and disposal practices for debris, grit, <br /> screenings, and biosolids: <br /> a. Method and frequency of disposal; <br /> b. Disposal site/area name(s) and location(s); <br /> c. On-site storage areas (must be lined to control leachate); and <br /> d. Public access controls. <br /> 9. A Title 22 Engineering Report for the use of reclaimed water is required for this project. The <br /> Department of Health Services is responsible for review and approval of the Title 22 report. You <br /> should anticipate approximately 60-90 days for DHS to review the report and provide comments. <br /> 10. Provide a copy of the floodplain redesignation documentation. <br /> C:WM=Ffl P itaV d p_WW1PJU�ftN 70301. O <br />
