These Studies, in their entirety, were <br /> found to be acceptable to EHD in their Approval Letter dated.A� ust 15 2008_ <br /> P g , <br /> E In the interim,Mr. Rodney Estrada received from the San Joaquin County Planning Department, <br /> a document produced by Mr. Amin Mahmood, the engineer for this project. There has now been <br /> a change in the number of daily services from one service to five services, with an anticipated 20 <br /> people at each service(plus one caretaker for a total of 21). Additionally, there will classes for <br /> approximately 40 children on the weekends. These changes in the number of on-site people will <br /> change the average daily flow (ADF), and consequently, the nitrate loading calculations. Mr. <br /> Estrada has requested this Addendum to document these changes in the calculations, as follows: <br /> i <br /> The original calculations for proie weekly wastewater flw were estimated to be; <br /> I <br /> 4, ople x 5 gals/person x 6 d/week=630 gals <br /> 29 eo le x 5 gals/person x 1 d/week= <br /> p g p eek 1,475 gals <br /> Total wastewater flow per week=2,105 gals/week I <br /> Total wastewater flow per year.=2,105 x 52 weeks/yr= 109,460 gals/yr <br /> The proposed increase of five services mr dgy, each with 21 people and 40 students on e <br /> weekends will now theoretically create a total wastewater flow on a weekly and yearly basis to be: <br /> 21 people x 5 services per day x 5 gals/person x 6 d/week= 3,150 gals <br /> 295 people x 5 gals/person x 1 d/week(Fridays) = 1,475 gals <br /> 40 students x 5 gal/student x 2 d/week (Saturday and Sunday) =400 gals <br /> Total wastewater flow per week =5,025 gals/week <br /> Total wastewater flow per year=5,025 x 52 weeks/yr= 261,300 gals/yr � <br /> Page 1 of 3 <br /> P.
