The expansion will result in <br />additional wastewater generation. <br />WASTEWATER CHARACTERIZATION <br />12. The Discharger has implemented water conservation practices which have reduced <br />the ratio of wastewater gallons produced per gallon of wine, as tabulated below. <br />Typically, reducing the volume of wastewater generated increases the concentration of <br />waste constituents in the remaining wastewater. The Discharger has improved source <br />control and wastewater treatment at the facility in response to increased waste <br />constituent concentrations associated with water conservation. <br />Year Wine Produced1 <br />(Mgal/year) <br />Wastewater Produced <br />(Mgal/year) <br />Wastewater/Wine Ratio <br />(gal/gal) <br />2003 27 80 2.91 <br />2004 28 68 2.41 <br />2005 30 77 2.56 <br />2006 45 63 1.40 <br />2007 43 58 1.36 <br />2008 47 53 1.13 <br />2009 36 52 1.43 <br />1 Total gallons of wine include bulk wine shipped and cases bottled (9 liter equivalent). <br />13.

To characterize the wastewater, samples were collected from
