Domestic wastewater flows are handled separately from the <br /> Process wastewater flows. <br /> SOLID WASTES <br /> Solid wastes from the winery include primarily pomace, seeds and stems. The estimated quantities of <br /> these wastes (at ultimate capacity) are as follows: <br /> Ultimate Annual Total - 35% x 100,000 tons = 35,000 tons <br /> I <br /> On the basis of a unit weight of 16 pounds per cubic foot, the annual volume of solids wastes would be: <br /> 70.0 x 106 lbs x 1 cubic yard <br /> 16 lbs/CF 27 cubic feet — 162,000 C.Y. <br /> The solid wastes will be hauled to an approved disposal site for disposal. <br /> Solids, in the form of sludge, accumulate in the ponds requiring periodic removal every 5 to 10 years. <br /> Those highly decomposed solids could be either dried and spread in a vineyard area or transported to a <br /> solid waste disposal site. <br /> M OTHER CONSIDERATIONS <br /> i Odor Control <br /> There should be no obnoxious odors from a properly designed and operated treatment system of this <br /> type. <br /> i <br /> t Ground Water Contamination <br /> The nearest water well to the winery process wastewater treatment and disposal systems is <br /> approximately 1,650 feet from the aerated lagoons. No disposal of reclaimed wastewater will occur <br /> within 100 feet of any existing wells. <br /> The groundwater in the pond area will be protected from possible contamination by synthetic liners <br /> installed in each pond. <br /> Irrigation/disposal of treated effluent is considered a beneficial use and is considered an effective means <br /> to protect groundwater quality. <br />
