1 I� Project Number E05174A Additional Nitrate Loading EstimateI , SKS Enterprises 23709 E. Brandt Road, Lodi, CA 1` Calculate mass of Nitrogen -N from Septic System: Septic system effluent quantity will be up t�1518 gpd (from Table 1 of the report). a Septic system effluent average concentration (Nw) is 60 mg/L-N (from Section 3.4.1 of the report). 1518 gpd x 365 dayslyear= 554,070 galloris per year(septic system waste water). �{ 3.785 liters is 1 gallon �! 554,070 gallons x 3.785 literslgalion =2,097,155 liters/year(septic system waste water). 2,097,154 liters/year x 60 mg/L-N = 125,829,240 mg/year 125,829,240 mg/year x 1 gram/ 1000 mg =:.125,829 grams/year 125,829 grams/year x 1 pound/453.59 grams= 277.41 lbs Nlyear(from septic system) �. 277 lbs Nlyear(from septic system) Calculate mass of Nitrogen-N and volume from Rain Fall: I Total average rain fall on the site is 17.57 inches(from Section 3.2 of the report). Average concentration of rain water is 1 mg/L-N (from Section 3.2 of the report). The site is composed of three parcels of 363.6 acres, 157.04 acres and 153.17 acres totaling 673.81,�acres. 17.57 inches x 1 ft112 inches x 673.81 acres x 43,560 sflacre x 28.3 literslcf= 1,216,192,369 liters/year 1 mg/L-N x 1,216,192,369 liters/year= 1,21'6,192,369 mg/year(from rain fall) ` 1 pound=453.59 grams and 1 mg = 0.001 grams 1,216,192,369 mg x 1 gram/1000 mg x 1 Ibf453.59 grams=2,681 lbs/year N (from rain fall] 2,681 lbs/year(from rainfall) i E Calculate mass of Nitrogen-N form manurelcompost: During the composting process, approximately 113 of the volume is reduced including the carbon addatives (SKS Enterprises). Total N per yard (wet compost) is 15.07 Ibsi(http:Ilcsanr.wsu.edulresourceslcompostlCc2.PDF). Each bird house generates 15 to 20 yards of manure per day(17.5 yards average). Six houses are planned for total build out, e: not the nine shown on the site plan. 112 of the compost will be applied to the fields. Eventually, SKS Enterprises will sell or give 100 %of the compost away(SKS Enterprises). There is an average of 10.87 lbs of N per yard of compost Http://csanr.wsu.edu/resources/compost/6c2.PDF, results of a composting study). 17.5 yards/day manure X 6 houses = 105 yards/day(at full build out) During composting, manure volume loss is approximtely 113 according to SKS Enterprises 105 yards/day manure x 0.66 (113 loss during composting) =70 yards/day compost �k i r
