Turner Road <br /> Lodi, CA 95242 <br /> INCO11PLETE REPORT OF WASTE DISCHARGE, REQUEST FOR ADDITIONAL <br /> INFORMATION, JESSIE'S GROVE WINERY, LODI, SAN JOA QUIN COUNTY <br /> I have reviewed Fall Creek Engineering's April 2002 Report of Waste Discharge Engineering Report <br /> and May 2002 Engineering Report and Specifications prepared as the Report of Waste Discharge <br /> (RWD) for Jessie's Grove Winery in Lodi, San Joaquin County. The reports were submitted in response <br /> to a 7 March 2002 Regional Board request for additional information. <br /> The following items require additional description in order to complete the RWD: <br /> 0 The RWD indicates wastewater can be discharged to the stormwater pond and Figure 4.4 <br /> presents areas of the pond three feet deep and one foot deep. Because wastewater can be <br /> discharged to the pond, the pond must comply with all wastewater storage pond requirements. <br /> Those include a minimum freeboard of two-feet, control of plant growth/scum/algae etc., a <br /> minimum dissolved oxygen concentration of one milligram per liter(mg/1), and groundwater <br /> monitoring. Figure C3 of the Specifications report shows the depth of the stormwater pond is <br /> 24-inches. Please address the discrepancy between the two reports (two or three feet deep) and <br /> describe how the stormwater pond will be reconfigured to address the freeboard issue. <br /> • We are concerned about potential groundwater degradation from the discharge of wastewater that <br /> contains elevated concentrations of dissolved solids. Because all water discharged to the <br /> stormwater pond will first travel through a constructed wetland, evapotranspiration processes are <br /> likely to raise the dissolved solids concentration to levels of concern. The water balance for <br /> normal rainfall years shows little or no outflow from the wetland in the months May through <br /> August while wastewater storage in the wetland is maintained from continuing discharges. <br /> Please address the dissolved solids concentration increase in the wastewater and the potential for <br /> the discharge to impact groundwater quality. <br /> • The RWD section 4.3.3 describes plant sensitivity to dissolved solids, chloride, sodium, pH, and <br /> boron. The values discussed in the section may be helpful in evaluating plants for land <br /> application evaluation but are not indicators of WDRs effluent limits.
