� J <br /> WASTE DISCHARGE REQUIREMENTS ORDER NO. -2- <br /> HOUSLEY FAMILY INVESTMENTS DBA HOUSLEY VINEYARDS WINERY <br /> SAN JOAQUIN COUNTY <br /> Wine Additive Wine Fining Agent Cleaner/Sanitizer <br /> Sulfur Dioxide Bentonite Trisodium Phosphate <br /> Malic Acid Caustic Soda (NaOH) <br /> Tartaric Acid <br /> 9. Winery wastewater will be screened at floor drains, and settleable solids removed in two 1,500 <br /> gallon three-stage gravity clarifiers. Effluent from the clarifiers will be pumped to the vineyard for <br /> irrigation. Screenings at the floor drains will be collected and placed into trash dumpsters for off- <br /> site disposal, settleable material collected in the clarifiers will be pumped and disposed of at a <br /> landfill. <br /> 10. Pomace and other grape wastes (skins, seeds, pulp, and stems) from the primary fermentation <br /> process in the winery will be composted on-site and tilled into the vineyard soil. Filter press <br /> materials will be stored on-site for eventual tilling into vineyard soil. Yeasts and solids generated <br /> in the secondary fermentation process will be washed out of the tanks and into the floor drains. <br /> 11. The winery is expected to expand its operations in the future. These waste discharge requirements <br /> include a provision for installation of a meter to determine the wastewater disposal rate. <br /> 12. Because the Housley Vineyards Winery has not yet been constructed, typical winery wastewater <br /> data is presented. Compound concentrations in winery wastewater are the highest during the crush <br /> season, typically in the following ranges: <br /> Compound Units Concentration Range' <br /> pH pH units 2.5 - 9.5 <br /> Dissolved Oxygen mg/1 0.5 -8.5 <br /> Biochemical Oxygen Demand (BOD 5)2 mg/1 500- 12,000 <br /> Chemical Oxygen Demand (COD) mg/1 800- 15,000 <br /> Grease mg/1 5 -30 <br /> Settleable Solids mg/1 25 - 100 <br /> Nonfilterable Residue mg/1 40- 800 <br /> Volatile Suspended Solids mg/1 150-700 <br /> Total Dissolved Solids (TDS) mg/1 80-2,900 <br /> Nitrogen mg/1 1 -40 <br /> Nitrate (as Nitrate) mg/1 0.5-4.8 <br /> Phosphorous mg/1 1 - 10 <br /> Sodium mg/1 35 -200 <br /> Alkalinity(CaCO3) mg/I 40-730 <br /> Chloride mg/1 3 -250 <br /> Sulfate mg/1 10 - 75 <br /> Typical chemical analyses of winery wastewater from Sutnmit Engineering, "Process Design Wastewater <br /> Management System, Design Criteria,"5 June 1998. <br /> z Five-day,20°Celsius Biochemical Oxygen Demand. <br /> C-T,j.
