5 n <br /> M F November 30, 2007 <br /> NOA Project Number: E07188A <br /> FI3.4 Future On-Site Sources of Nitrate <br /> 3.4.1 Quantity and Quality ofDomestic Wastewater From Proposed Project <br /> The following discussion is for determining the long-term waste water flow generated from the <br /> proposed construction for the nitrate loading analysis and should not be used for septic system <br /> design purposes. Typically,use estimates for the sizing of septic systems include a peak use factor, <br /> whereas the numbers discussed here are based on long-term averages. <br /> Th` aitn expec ed septic tank usage for the site will be from various buildings. An office <br /> building will have five to six people working with no customers. Six to eight employees and no <br /> customers will work at a repair shop on site. A dispatch building will have four people working, and <br /> F1there will be four people working at a washing facility. Forty to fifty truckers will be coming and <br /> going throughout the day. The facility will be open normal business hours, five days a week in the <br /> approximately eight winter months of November through June, and will be open six days a week in <br /> the summer months,July though October._Several-septic-systems-are being-pro os for <br /> onstructt <br /> The estimated sewage flow rates for use categories are available from a number of references. The <br /> uses presented below were guided by the San Joaquin County On-Site Wastewater Disposal Standards <br /> (2003), Crites and Tchobanoglous (1998), and EPA (1980). The references indicate that 13 gallons <br /> Fi for each employee is typical for an office worker and 5 gallons for each truck driver. (Crites and <br /> Tchobanoglous, 1998). A shower is proposed in the repair shop which will serve a maximum of ten <br /> to fifteen people a day. <br /> e-` The following table presents the septic waste water uses associated with the Site. The rates <br /> presented from the references provide general guidance but do not always reflect a match in usage. <br /> Fill Careful examination, professional judgement, and experience are necessary to select a reasonable <br /> flow rate estimate. The flow rates selected for the uses associated with this project are presented <br /> next. <br /> Table 1. <br /> Typical Quantity of Effluent <br /> Category Total People per Average Quantity per Average Daily Flow <br /> F Day Person Per Parcel <br /> Shower 15 35gal/day/employee (15 employees* 35 gpd) = 525 gpd <br /> Truckers 50 5 gal/day/trucker (50 truckers* 5 gpd) = 250 gpd <br /> Employees 22 13 gal/day/employee (22 employees* 13 gpd) = 286 gpd <br /> F11 Total 1,061 d <br /> l Note —gpd is gallons per day. <br /> 5 <br />
