WASTE DISCHARGE REQUIRONTS ORDER NO. • -2- <br /> RODNEY AND GAYLA SCHATZ <br /> MOKELUMNE RIM VINEYARDS <br /> SAN JOAQUIN COUNTY <br /> 6. Because process wastewater monitoring data for the Discharger's winery is not yet available, <br /> typical winery wastewater data are presented below. Constituent concentrations are the highest <br /> during the crush season, and are typically in the following ranges: <br /> Compound Units Concentration Rang <br /> PH pH units 2.5 -9.5 <br /> Dissolved Oxygen Mg/L 0.5 - 8.5 <br /> Biochemical Oxygen Demand (BOD5)2 Mg/L 500- 12,000 <br /> Chemical Oxygen Demand (COD) Mg/L 800- 15,000 <br /> Grease Mg/L 5 -30 <br /> Settleable Solids Mg/L 25 - 100 <br /> Nonfilterable Residue Mg/L 40- 800 <br /> Volatile Suspended Solids Mg/L 150- 700 <br /> Total Dissolved Solids (TDS) Mg/L 80-2,900 <br /> Nitrogen Mg/L 1 -40 <br /> Nitrate (as Nitrate) Mg/L 0.5 -4.8 <br /> Phosphorous mg/L 1 - 10 <br /> Sodium mg/L 35 -200 <br /> Alkalinity(CaCO3) mg/L 40-730 <br /> Chloride mg/L 3 -250 <br /> Sulfate mg/L 10 - 75 <br /> Typical chemical analyses of winery wastewater from Sumrnit Engineering, Process Wastewater <br /> Management System,Design Criteria and Calculations, 9 July 2001. <br /> 2 Five-day, 20°Celsius Biochemical Oxygen Demand <br /> WASTEWATER TREATMENT SYSTEM <br /> 7. Wastewater generated from winery processing activities (process/equipment cleaning, washdown <br /> operations, and bottling) is collected in floor drains, drains to a sump, is pumped out of the sump, <br /> is flow metered, and then is screened and either discharged directly to the land application area or <br /> treated in an aerated storage pond. A schematic of the wastewater system is provided in <br /> Attachment B, which is attached hereto and made part of this Order by reference. This Order <br /> prohibits further direct land discharge of partially treated wastewater. <br /> 8. The wastewater storage pond was constructed approximately 12 feet deep with 8 feet below the <br /> surrounding elevation and a 4 feet high berm at ground surface. Allowing for two feet of <br /> freeboard, the total storage volume is approximately 347,000 gallons. The RWD did not provide <br /> any information on the permeability of the soil underlying the pond. <br /> 9. The RWD contains a water balance for the wastewater treatment, storage, and land application <br /> system. The water balance was based on annual wastewater discharge of 1,650,000 gallons and <br /> 100-year annual return rainfall amounts. The water balance shows that the wastewater pond has <br /> V:`Syi_loaquin_Non 15\Su1P.0briami.S,i lo:pu-Mokclumnc Rim Vince ds\WDRr1.doc <br />
