I-W INFORMATION SHEET ORDER NO. R5-2004-0079 SPENKER RANCH, INC. JESSIE'S GROVE WINERY SAN JOAQUIN COUNTY Jessie's Grove Winery is located at 1973 W. Turner Road, Lodi. Spenker Ranch, Inc. owns the land at the winery and the land application areas, while Jessie's Grove Winery operates the facility. Jessie's Grove Winery and Spenker Ranch Inc. are jointly referred to as Discharger. The winery will process approximately 700 tons of grapes annually to produce approximately 110,000 gallons of wine that will be sold both as bulk wine and bottled wine. Approximately 7,000 cases (17,000 gallons) of wine will be bottled on-site. Wastewater is generated in tank cleaning, grape crushing, and equipment/floor cleaning. A mobile contract wine bottling service is used to bottle the wine; therefore, bottling activities will not generate a high strength waste stream. The winery is located outdoors. Stormwater that falls on roofs, paved areas, and the winery is currently collected and discharged to the wastewater system; however, the Discharger may install a diversion valve to allow clean stormwater to enter a designated stormwater pond. Domestic wastewater is discharged to a septic tank and leachfield system. The domestic system is regulated by the San Joaquin County Environmental Health Department. The Discharger has proposed treating wastewater in a system that has been partially constructed; this Order requires construction and use of the system by 2 September 2004 (prior to crush activities). Process wastewater treatment will consist of collection of wastewater in floor drains with screens, additional screening with a hyperbolic screen, settling in a 1,000 gallon septic tank, and application to a 70 acre cropped land application area. The Discharger proposes to dispose of screened and settled winery effluent by irrigating 70 acres of cropped pasture using a water truck. A sprinkler irrigation system is under consideration and is acceptable as long as the application is performed consistent with the requirements in this order. The monthly average process wastewater flow rate is anticipated to be 2,000 gallons per day(gpd) except during the crush (September through November) when wastewater flow rate is anticipated to be 3,500 gpd. The wastewater flow rate described above does not include rainfall that will combine with the industrial wastewater. The annual volume of wastewater shall not exceed 900,000 gallons. The amount of wastewater that will be generated does not meet the crop demand for irrigation; therefore supplemental irrigation water will also be applied to the land area. It is anticipated that the cropping activities in the land application area will utilize all the nitrogen applied in the wastewater. Dissolved solids in the wastewater are a concern despite relatively low loading rates. Plants take up some dissolved solids at variable rates up to of 2,000 lbs/acre-year, so the proposed loading rate, depending on the analytes present in the wastewater, may degrade groundwater. The Discharger is therefore required to install groundwater monitoring wells. This Order requires preparation of a Groundwater Monitoring Workplan, Wastewater Treatment System Construction Report and Land Application Area Improvement Report, Operation and Maintenance Plan, Groundwater Well Installation Report, Salinity Reduction Study, and a Background Groundwater Quality Study Report. The WDRs allow the Discharger to increase the land application area and add
