s <br /> 6aT1TECHNICAL ENGINEERING REPORT J- <br /> TURNER WINERY WASTEWATER SYSTEM <br /> BACKGROUND <br /> The winery produces wine by fermentation and periodically produces <br /> alcohol by distillation of wine. Winery washwater is discharged to <br /> shallow ponds for disposal by percolation and evaporation. Stillage <br /> waste, which is produced about 20 days out of the year, is applied <br /> directly to the land for treatment and disposal. <br /> On November 16, 1984, the Regional Water Quality Control Board (RWQCB) <br /> contacted Turner Winery concerning recurring odor problems from the <br /> winery wastewater facilities. The RWQCB requested a technical plan for <br /> system improvements including: <br /> 1. Complete wastewater characterization <br /> 2. Site evaluation <br /> .3. Recommended action plan <br /> On April 11 , 1985, Turner Winery hired George S. Nolte and Associates to <br /> prepare the technical plan. <br /> WASTEWATER.
