The <br />Wine Group has applied for art update of the waste discharge requirements. The winery"s <br />discharge was previously regulated under the Board's Order No_ 79-146 which was for the <br />disposal of the winery waste*ater to 30 acres of evaporatioulpercoiation basins, All wastevrdters <br />are discharged to land. <br />The Wine Group's Wiuety produces up to 0.5 million gallonsper day (mgd) of one -pass cooling <br />water and geaccal winery wastewater. 'Phis updated Order wM allow the wastewater to be used for <br />melting the irrigating needs of up to 330 acres of grape vines when all vineyards are planted. <br />During the irrigation/growing months of the grape vines the v&cry's wastewater wM have to be <br />supplemented with South San Joaquin Ligation District water or from on-site production wells to <br />meet the grapes water requirements. Luring the winter mouths the winery's wastewater wM be <br />spread beneath the dormant grape vines and allowed to evapordte azidlor percolate into the <br />permeable sandy soib. <br />The general winery wastewater consists of crush equipmcat washwater, sbMage waste, general <br />cellar waste, neutralized water from an ion exchange unit, storm water runof storage water <br />contalni.ng,sulfur dioxide, and vacuum filter wastewater. Chlorine, trisodium phosphate, sodium <br />hydroxide, sodium carbonate, sulfamic acid, citric acid, sulivric acid, ammonia, and sulfur dioxide <br />ace added at vatidus points it the winery, primarily for disinfection, cle, nin R, and neutralization. <br />The 330 acres of vineyard wM be divided into smaller areas during the non -irrigating months of the <br />year and wM reee vc no more wastewater than what can be evaporated or percolated in a 48-hour <br />period after application. Each field area during the non -irrigating monduwill be allowed to dry <br />between 10 to 30 days after wastewater application before wastewater is re-applied. In addition, <br />the soils in the fields will be tilled in each,ama to incorporate the yeast cells, grape solids, stems, <br />and pomace that may build up from the wastcwaher. <br />Surface drainage is normally to unnamed tributaries of the Sate Joaquin River. However. at the <br />winery, storm water and wash down drainage from the operations area arc contained within the <br />facility and will, be discharged to the vineyard. <br />MHM <br />Ei ' d 9ZO , ow -inskoo sm-ii Aa3wum WdET : b 5002' t "E3d <br />
