WASTE DISCHARGE REQUIREMENTS ORDER R5-2012-0103 - 6 - <br />CONSTELLATION BRANDS U.S. OPERATIONS, INC. dba WOODBRIDGE WINERY <br />WOODBRIDGE WINERY <br />SAN JOAQUIN COUNTY <br /> <br /> <br /> <br />a. Refrigeration Cooling Tower Make-up Water <br />b. Winery Cleanup Water <br />c. Pressure Washing <br />d. Landscape Irrigation <br />The Discharger may implement some of these reuse options. <br />18. The quality of wastewater discharged to the LAAs has been monitored in accordance <br />with Order 87-184. As described above, data collected before November 2008 <br />represents untreated winery wastewater. After that time, portions of the treatment <br />system were installed and began operation. These data indicate that the Discharger’s <br />salinity reduction efforts have not significantly reduced the concentration of FDS. <br />However, as discussed below, potassium has a higher molecular weight than sodium, <br />so substitution of potassium-based cleaning solutions may not be reflected in the FDS <br />results. The annual mean wastewater characterization data are summarized below: <br />Annual <br />Averages <br />Annual Mean Result, milligrams per liter (mg/L) <br />pH1 BOD Sulfate NO 3 as N TKN TN TDS VDS FDS <br />2002 1,928 51 0.9 19 19 839 370 469 6.3 <br />2003 5,009 73 1.0 18 19 1,022 492 530 5.2 <br />2004 5,836 168 1.5 33 34.2 1,970 969 1,001 4.6 <br />2005 3,830 82 0.8 40 40.7 1,079 486 593 5.0 <br />2006 5,444 126 1.6 14 15.6 1,522 693 829 5.0 <br />2007 4,058 264 0.8 25 25.3 2,205 1,034 1,171 5.1 <br />2008 5,686 93 0.9 23 24 1,505 858 665 5.8 <br />20092 1,393 8 ND 44 45 1,956 907 1,049 7.2 <br />20102 53 13 36 4 40 1,580 574 1,006 8.8 <br />1 pH values reported as median values. 2 Data collected after November 2008 includes partially or completely treated wastewater. <br />19. Wastewater flows are measured downstream of the influent pump station, downstream <br />of the clarifier and DAF treatment equipment prior to discharge to the lower ponds, and <br />prior to discharge to the LAAs. <br />a. Storm water that falls on a portion of the facility will be comingled with the <br />wastewater. The RWD estimates 9.7 million gallons of storm water will be added in <br />a normal rainfall year and 20.4 million gallons will be added in a 100-year, 365-day <br />precipitation event.
