INFORMATION SHEET <br /> ORDER NO. 5-00-182 <br /> R. LAWSON ENTERPRISES DBA WILDROSE VINEYARDS <br /> SAN JOAQUIN COUNTY <br /> WildRose Vineyards operates a winery at 8751 E. Highway 12, east of Lodi in San Joaquin County. <br /> The winery is on a 20.9 acre parcel owned by R. Lawson Enterprises,which consists vineyards and <br /> cherry orchards. On 6 October 1999 WildRose Vineyards was granted a one-year waiver of WDRs in <br /> order to monitor the wastewater quality in 1999 and prepare a Report of Waste Discharge. WildRose <br /> Vineyards failed to collect the wastewater data. These WDRs were prepared based on typical winery <br /> wastewater data. Operations at this winery are proposed to expand in the fixture based on economic <br /> considerations. Maximum discharges of winery wastewater will be approximately 5,000 gallons per <br /> day and will occur during the crush season, generally between August and October. <br /> Grape wastes from the primary fermentation process in the winery will be placed into bins for off-site <br /> composting and eventual tilling into vineyard soil. Wastes from the secondary fermentation process <br /> will be settled in a two-stage clarifier or discharged to the land application area with the winery <br /> wastewater. Settleable material contained in the clarifier will be placed into a trash bin for off-site <br /> disposal. <br /> Wastewaters from the two-stage clarifier will be land-applied to the vineyard or orchard cropland when <br /> climatic conditions allow. When conditions don't allow application, the wastewater will be stored in a <br /> 12,000 gallon aboveground storage tank. Stormwater and tank defrost water will be discharged to the <br /> cropland. Discharge of stormwater and tank defrost water during rain events will be allowed, although <br /> not to areas with saturated soil. <br /> Depth to shallow groundwater is approximately 60 to 70 feet. The shallow soils are sandy/silts to <br /> silty/sands with relatively high permeability rates. Process water is obtained from municipal supply. <br /> The property was formerly primarily used as a cherry brining facility, and cherry brining still occurs at <br /> the site. The cherry briner discharges wastewater to a wastewater pond that exists in the northeast area <br /> of the property. The briner's discharge of wastewater to the pond is occurring under Title 27 WDRs <br /> Order No. 92-154. These WDRs prohibit commingling CFP and winery wastewaters. When these <br /> WDRs were prepared, the wastewater pond was being investigated as a source of elevated groundwater <br /> salinity. Three groundwater monitoring wells exist at the wastewater pond. These WDRs do not <br /> address the waste from the cherry brining operation and prohibit WildRose from discharging winery <br /> wastewater, defrost water, stormwater, and other liquids to the pond. <br /> Under these Waste Discharge Requirements, monitoring of the winery wastewater effluent, and <br /> underlying groundwater will be required. Groundwater monitoring wells will be installed to monitor <br /> shallow groundwater. Monitoring data will be used to determine whether additional wastewater <br /> treatment is necessary. <br /> TRO:08/04/00 <br /> C W,wwmm:vara�m�e�ww,�rrzow�.eo� <br />
