WASTE DISCHARGE REQUIREMENTS ORDER R5-2012-0103 - 5 - CONSTELLATION BRANDS U.S. OPERATIONS, INC. dba WOODBRIDGE WINERY WOODBRIDGE WINERY SAN JOAQUIN COUNTY b. A new influent pump station is equipped with three 1,100 gpm non-clogging pumps. Flow rates greater than 1,100 gpm will be produced during heavy rainfall events. Such flows will be predominantly storm water, which will be diverted to the Lower Ponds. c. Two 700,000 gallon tanks allow for hydraulic and concentration equalization and control for more uniform quality and quantity of wastewater management. A portion of the effluent from the anaerobic treatment system can be recycled back into the equalization tanks. d. A Mobilized Film Technology (MFT) treatment system provides a high rate anaerobic process. The MFT system includes preconditioning, MFT bioreactors, biogas processing with energy capture, and a Dissolved Air Floatation (DAF) system to remove suspended solids. The MFT system is constructed above- ground. e. Three 3.3 million gallon aeration ponds (Upper Ponds) are used to oxidize the anaerobic system effluent. The ponds are double-lined with high density polyethylene (HDPE) and have leak detection systems. The Upper Ponds are equipped with brush aerators and dissolved oxygen probes to optimize aerator operation. f. Solids from both the anaerobic and aerobic processes will settle in the Upper Ponds. The solids will be removed as needed and disposed of by delivery to a permitted composting operation, delivery for livestock feed, or for further processing at appropriately permitted facilities. Effluent from the Upper Ponds will be further treated (on an as-needed basis) to reduce the solids content using a filtration unit to prevent clogging of the sprinkler irrigation system. g. The Lower Ponds are used primarily for storm water detention and can also be used for treated wastewater storage. The Lower Ponds, which are unlined, provide 23 million gallons of storage capacity. The Lower Ponds are vulnerable to inundation by the Mokelumne River during 100-year flood events. The Central Valley Water Board has permitted surface water discharges from the Lower Ponds if they become inundated by flood waters under the Low Threat General Waste Discharge Requirements Order R5-2008-0081. Otherwise, surface water discharges from the lower ponds are not permitted. h. The Discharger currently applies treated wastewater to 75 acres of LAAs. The Discharger proposes to expand the LAAs to approximately 101 acres as wastewater flows increase. 17. In addition to the wastewater system described above, the Discharger has identified potential treated wastewater reuse opportunities. All of the reuse opportunities would require installation of distribution piping and some require additional treatment before the wastewater would be of sufficient quality. The identified reuse opportunities consist of:
