WASTE DISCHARGE REQUIREMENTS ORDER R5-2012-0103 - 4 - CONSTELLATION BRANDS U.S. OPERATIONS, INC. dba WOODBRIDGE WINERY WOODBRIDGE WINERY SAN JOAQUIN COUNTY discrete waste streams. Because some characterization is based on grab samples, mathematical calculations resulted in some inconsistent results. For example, some “percent of total” values exceed 100-percent. The Discharger considers the data accurate enough to characterize the wastewater components. A summary of the data is provided below. Waste Stream Waste Volume (Mgal/yr) BOD Load FDS Load Total Nitrogen Load (ton/yr) (% of total) (ton/yr) (% of total) (ton/yr) (% of total) Bottling 19.5 236.4 20 45.9 22 1.4 8 Water Softening 0.25 0.0 0 49.7 23 0.0 0 Refrigeration 4.76 1.3 0.1 22.3 10 1.2 7 Tank Sanitation 5.37 106.0 9 66.6 31 1.4 8 Barrel Rinsing 5.00 477.5 40 52.7 25 4.6 27 Filtering 3.06 234.1 20 31.8 15 0.4 3 Totals 50.62 1,055.2 88 269.1 126 9.0 53 After completion of this study, the Discharger improved biological treatment of the wastewater and implemented source control to reduce salinity. WASTEWATER TREATMENT SYSTEM 14. Wastewater is collected in a gravity drain system. Because much of the facility is exposed to the elements, storm water that falls on cellar processing areas of the winery is also collected in the drain system. The collected wastewater and/or storm water is piped to the wastewater treatment system. 15. At the time the CDO was adopted in 2007, the Discharger’s treatment system consisted of the so-called Lower Ponds and 87 acres of LAAs, 57 acres of which were cropped with grapes. Since that time, the Discharger has completed several facility and operation improvements, including completion of a new wastewater treatment system, construction of two new LAAs totaling 26 acres, salinity reduction, and LAA operational improvements. These changes are discussed further below. The wastewater system was constructed in three phases; Phase 1 was completed in November 2008, Phase 2 was completed in August 2009, and Phase 3 is ongoing and consists primarily of improved distribution and storage of treated wastewater. 16. The treatment system includes the following major elements. Attachment C, which is attached hereto and made part of this Order by reference, presents a flow diagram that identifies the various wastewater streams. a. Improved wastewater screening using a self-cleaning slotted screen removes gross solids and is designed to accommodate the peak crush flow of 1.5 mgd.
