Since no fertilizers are applied to the vineyard, the nitrate loading calculation will <br /> not address the contribution from agriculture. The contribution is estimated to be minimal to <br /> none. <br /> 7.2 Quantity and Quality of Winery Wastewater <br /> The proposed small winery may generate a maximum of 200 tons of grapes or 36,000 gallons of <br /> wine per year. All the wastewater generated from winery operations is planned to be tanked and <br /> hauled off site. Therefore, no contribution from winery wastewater will be utilized for the nitrate <br /> loading analysis. <br /> 7.3 Quantity and Quality of Domestic Wastewater <br /> The average total nitrogen concentration of the domestic waste water is normally considered to <br /> be 20-85 mg/L-N with a typical concentration of 45 mg/L-N(Crites and Tchobanoglous, 1998). <br /> The small winery is expected to employ two (2)persons, Friday thru Sunday, weekly. Five(5) <br /> customers per day are estimated to visit the winery tasting room each day. The estimated <br /> concentration of total nitrogen of the waste water is estimate to be 45 mg/L-N. The estimated <br /> flow generated for each new parcel is as follows: <br /> Table 5. <br /> Estimated Daily Quantity of Effluent for Winery. <br /> —.

The weather <br /> station information for Lodi's precipitation and evaporation was used to estimate the deep <br /> percolation of rain for the site. The deep percolation of rain was estimated to be 6.84 inches. <br /> ?oeRso <br /> 'f. W <br /> O � <br /> 1 r <br /> JS pL\ <br />
