P November 8, 2005 NOA Project Number: E05123B I� 1 In addition to solid waste,wash water generated from the plant is estimated to be 10,700 gallons in 2006 to 29,900 gallons in 2008. The report indicated the fruit processing days which generate waste water will increase from five days for 2006 to 15 days for 2008. The peak operating season for the facility is approximately 40 days per year. According to information from Jeff Colombini of Lodi Farming and Gregory Stahl of Ground Zero Analysis, Inc., the solid waste generated from the site will be hauled of the site and land applied to neighboring fields. The waste water will be.applied to neighboring field at agronomic rates. The ;gwi c. F�41 Regional Water Quality Control Board will oversee the permitting of these discharges. For the purpose of the nitrate loading study, the solid and liquid wastes will be applied off the 8.2 acre site._No contribution of nitrates in solid or liquid wastes will be considered for the nitrate loading bala-nrc. 3.4 Future On-Site Sources of Nitrate 3.4.1 Quantity and Quality ofDomestic Wastewater From Proposed Project F1 The followingdiscussion is for determining the long-term waste water flow generated from the g g proposed residences for the nitrate loading analysis and should not be used for septic system design Fpurposes. Typically,use estimates for the sizing of septic systems include a peak use factor,whereas the numbers discussed here are based on long-term averages. We understand from Jeff Colombini of Lodi Farming, that during the busy processing period,which will last 40 days per year, the staff will consist of three employees working two 12-hour shifts, seven days per week. During other times of the year (remaining 325 days of the year),Jeff Colombini indicated maybe one or two employees will visit the site once or twice a week for limited periods. No visitors or customers are planned at any time. F1The estimated sewage flow rates for use categories are available from a number of references. The uses presented below were guided by the San Joaquin County On-Site i,IVastewater Disposal Standards (2003), Crites and Tchobanoglous (1998), and EPA (1980). We estimate that one shift worker for F112 hours will generate about 15 gallons per day waste water. The following tables presents the septic waste water uses associated with the Site. The rates presented from the references provide general guidance but do not always reflect a match in usage. Careful examination,professional judgement, and experience are necessary to select a reasonable flow rate estimate. The flow rates selected for the uses associated with this project are presented next. 5 F1
