WASTE DISCHARGE REQUIREMENTS ORDER R5-2012-0103 - 10 - CONSTELLATION BRANDS U.S. OPERATIONS, INC. dba WOODBRIDGE WINERY WOODBRIDGE WINERY SAN JOAQUIN COUNTY k. Incorporation of source control and waste minimization into the employee training program. 23. The Discharger has not provided wastewater monitoring data or calculations to quantify the level of salinity reduction that has been achieved by the measures identified in the Process Water Characterization Report described above. Therefore, this Order requires that the Discharger conduct a Salinity Reduction Study to demonstrate actual salinity reduction results. WATER BALANCE 24. A water balance was included in the RWD to demonstrate the capacity of the wastewater treatment, storage, and land application system. The water balance was based on an annual wastewater discharge of 100 Mgal, with a peak monthly flow of 21 Mgal. The water balance used the 100-year annual rainfall event and a total of 100 acres of LAAs. The water balance shows that the wastewater treatment, storage, and disposal system is adequate to support the projected flows at full build-out (i.e., 100 acres of LAAs). However, the Discharger has not completed the conveyance system and other site improvements for the new LAAs and therefore this Order contains interim flow limits based on the LAAs currently available with a provision to increase the flow limits to full capacity when the new LAA infrastructure is completed. 25. Storm water draining from roofed areas and surrounding surface areas that does not come in contact with wastewater is routed to the facility’s storm water drainage system. The storm water system pipes the water to a discharge point at the Mokelumne River. Storm water that falls on processing areas is directed to the wastewater system. When combined storm water and wastewater flow rates are above 1,100 gallons per minute (gpm), the combined discharge is directed to the unlined Lower Ponds. The Discharger has obtained coverage under the NPDES Low Threat General Waste Discharge Requirements, Order R5-2008-0081 for discharges from these ponds due to flood inundation. 26. The wastewater treatment and storage ponds are not large enough to allow storage of wastewater through the winter and land application only during the growing season. During a normal rainfall year, wastewater application during the rainy season will be minimal. During the 100-year annual precipitation event the Discharger will periodically land-apply wastewater throughout the rainy season except during actual rain events or when the soil is saturated. Because of the restrictions on applying wastewater contained in this Order, the Discharger will have to carefully schedule winery activities to manage the available storage in the wastewater ponds. Climatic or LAA conditions (saturated soil, odors, etc.) may require winery process schedule changes to comply with this Order.
