WASTE DISCHARGE REQUIREMENTS ORDER R5-2013-0028 -9- <br /> DELICATO VINEYARDS, INC. <br /> DELICATO FAMILY VINEYARDS <br /> SAN JOAQUIN COUNTY <br /> 32. The Discharger proposes to convert the existing 23 acres of uncropped LAAs to <br /> cropped LAAs and add approximately 107 acres of vineyards as new LAAs, for a <br /> total cropped LAA area of 130 acres. The existing and new LAA locations are <br /> shown on Attachment B and are summarized below. <br /> LAA Name Approx. Proposed Location <br /> Acres Land Use <br /> 1 7 Cropped Central portion of APN 204-040-15 <br /> 2 6 Vineyards Northern portion of APN 204-040-15 <br /> 3 16 Cropped APN 204-040-07 <br /> 4 15 Vineyards APN 204-040-08 and 204-040-09 <br /> 5 58 Vineyards APN 204-050-23 and 204-050-24 <br /> 6 28 Vineyards APN 204-050-14 <br /> 33. The 2004 CAO required that the Discharger complete the facility improvement <br /> design and propose an implementation schedule in the RWD, which was due by <br /> 1 February 2006. The April 2006 RWD did not include detailed design <br /> improvements. The Discharger is now proposing to expand facility operations, <br /> increase wastewater flows over a five-year period, and improve the wastewater <br /> management and disposal system prior to the 2013 crush season. Because these <br /> improvements are necessary to prevent further groundwater degradation, this <br /> Order establishes a time schedule to complete the improvements in accordance <br /> with the proposed plan. <br /> 34. An on-site agricultural well (Ag-1) currently provides irrigation water for the existing <br /> vineyards. The on-site agricultural well has a screened casing interval from <br /> approximately 255 to 305 feet below ground surface. Irrigation water provided by <br /> the on-site agricultural well is distributed directly to vineyard areas through a drip <br /> irrigation system. Water quality data from the sampling of the irrigation well in <br /> 2009 is provided below: <br /> Constituent Analytical Result <br /> (mg/L, except as noted) <br /> Total Hardness 149 <br /> Arsenic 0.009 <br /> Calcium 40 <br /> Magnesium 12 <br /> Potassium 5.0 <br /> Sodium 46 <br /> Sulfate 29 <br />
