WASTE DISCHARGE REQUIREaTS ORDER NO.R5-2002-0034 a 2 SUTTER HOME WINERY LODI FACILITY, SAN JOAQUIN COUNTY Chemical Name and Type Storage Agent (Quantity Stored Tartex (Caustic) Drum (in locked storage) 400 pounds Pil Chlor(HClaq) Drum (in locked storage) 100 pounds Sanibac (Chlorinated Cleaner) Drum(in locked storage) 400 pounds Trisodium,Phosphate. Drum(in locked storage)., ,265 pounds.- - 8. On 2 November 2001 the Discharger collected a sample of wastewater from each wastewater treatment pond. The data are presented below. Analyte Units Pond No. 1 Pond No. 2 BOD mg/L 76 15 Suspended Solids mg/L 290 97 pH Std. 8.5 9.0 Nitrate as N mg/L ND (0.1) ND (0.1) Total Kjeldahl Nitrogen mg/L 49 14 Ammonia as N mg/L 22 6.5 Total Dissolved Solids mg/L 2,000 2,300 Fixed Dissolved Solids mg/L 1,700 2,000 BOD denotes Biochemical Oxygen Demand. Data presented in 15 November 2001 Report of Waste Discharge. WASTEWATER SYSTEM 9. Wastewater is discharged to an existing wastewater treatment system consisting of two ponds and cropland. A site map of the winery is presented on Attachment B, which is attached hereto and made part of this Order by reference. 10. The wastewater flow is metered. The Discharger estimates a total flow of 4.0 million gallons a year at a rate of 10,000 to 16,000 gallons per day(gpd). Because the facility does not crush grapes, the wastewater flow rate is fairly consistent over the year. However, due to increased activity, wastewater flow rates are higher proceeding and during the crush season (May through October). 11. Process wastewater is collected in floor drains,piped to wastewater sumps, pumped to clay-lined facultative treatment ponds equipped with mechanical aerators, and then applied to 15.5 acres of cropland. 12. Winery wastewater and stormwater are pumped from sumps that discharge the wastewater either to the wastewater ponds or the stormwater pond, depending on an automated valve. The Discharger has developed operation and maintenance procedures that minimize the potential for discharge of process wastewater to the stormwater pond. However, because wastewater could accidentally be discharged to the stormwater pond, and because residual wastewater in floor drains and the sumps will commingle with stormwater, groundwater monitoring of the stormwater pond is required.
