Steve Ehlers - 2 - 13 September 2013 E2 Family Winery DISCHARGE DESCRIPTION E2 Family Winery is located at 9009 West Highway 12, San Joaquin County. The winery is located on approximately 362 acres (APN 025-08-002 and 025-08-003), which is used for seasonal crops, vineyards, and wine production. Structures at the property include a small office, a bottling and cased goods warehouse, a repair shop, and three aboveground silos. One of the silos is equipped with ten aboveground 12,000 gallon wine storage tanks, while the other two silos are used for crop storage. The Discharger generates approximately 7,000 gallons of winery process wastewater annually. Wastewater generated during crushing, bottling, and equipment cleaning is collected on a concrete-paved crush pad that drains into a concrete sump. Wastewater is then conveyed from the sump to a 7,500 gallon aboveground storage tank for solid settling before the water is discharged to 100 acres of cropped land used as a Land Application Area (LAA). The 100-acre LAA is split between 35 acres of vineyards and 65 acres of seasonally cropped land, although additional cropped acreage is also available. The perimeter of the LAA is surrounded with tailwater ditches to capture and prevent off-site surface water discharge. Wastewater is blended with water from an on-site agricultural well and then applied to the LAA through furrow irrigation. Approximately 50 gallons of evaporative cooling water is generated annually and is also mixed with irrigation water and applied to the LAA. The Discharger uses a portable steam cleaner to clean and sanitize equipment. which eliminates the use of chemicals. Approximately 300 pounds of pomace (stems, seeds, and skins) are generated from grape crushing activities conducted between September and November each year. Crushed solids (pomace) and skimmed solids recovered during fermentation (lees) are separated and stored on-site on a bermed section of an abandoned unpaved air strip until the material is tilled into shallow soil of the vineyard and other on-site crop areas. All storm water is retained on-site and discharged to a separate field than the 100-acre LAA. Because the crush pad is not covered and crushing does not occur during inclement weather, storm water generated at the winery does not come in contact with raw materials, nor is it collected with winery process wastewater. Although an on-site well is used for agricultural irrigation, drinking water is supplied from a local vendor and stored in a 250-gallon storage tank. Domestic wastewater is discharged to an on-site septic system permitted through the San Joaquin County Environmental Health Department.
