Fi f <br /> Fj August 22, 2007 <br /> NOA Project Number: E07109A <br /> 3.3 Current On-Site Sources of Nitrate <br /> Current on-site sources of nitrate include the one current septic stem on the property. No <br />� � p Y <br /> Fi additional sources of nitrates besides septic effluent,groundwater and rainfall are recognized. <br /> Fi3.4 Future On-Site Sources of Nitrate (Revised from Kleinfelder Report) <br /> 3.4.1uanti rl <br /> Q ty and Quahiy ofDomestrc Wastewater From Proposed Project <br /> The following discussion is for determining the long-term waste water flow generated from the <br /> proposed residences or commercial usage for the nitrate loading analysis and should not be used for <br /> septic system design purposes. Typically, use estimates for the sizing of septic systems include a <br /> peak use factor,whereas the numbers discussed here are based on long-term averages. <br /> The church is proposing to have / o emplo ees per day ap mately two to three days per week, <br /> art e. The church will serve up to 150 m tubers during two Lrvices, for a maximum number of <br /> 3F, 00 c urch attendants on Sundays` e fac' ' will have a y uth ministry on Tuesday, Wednesday <br /> nd F day. The church will have a sm b ak room for the part time staff only. According to the <br /> Pa r of the church, there are no dishwashers or washing machines. <br /> The following table presents the septic waste water uses associated with the site. The rates <br /> jpresented from the references provide general guidance but do not always reflect a match in usage. <br /> 1V � <br /> 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 2. <br /> Typical Quantity of Effluent j <br /> Day of Week Total Attendees Average Quantity per Average Daily Flow <br /> per Day Person(gal) Per Facility <br /> Monday no uses no uses d no uses <br /> Tuesday 10 2 A (10 people x 2 gal)/ 7 days = 2.9 gal <br /> Wednesday 50 2 k0 (50 people x 2 gal)/ 7 days =14.3 gal <br /> Thursday no uses no uses J no uses D <br /> Friday 12 2 (12 people x 2 gal)/ 7 days=3.4 gal <br /> Saturday no uses no uses O no uses 10 <br /> Sunday #.300 ,�2 ( J 300 people x 2 gal)/ 7 days = 85.7 gal 4j, I L <br /> TOTAL AVERAGE GALLONS PER DA 110 gallo s 1 <br /> i Note —gpd is gallons per day. <br /> ' <br /> U6 <br /> w H <br /> I i� <br />
