s CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD CENTRAL VALLEY REGION ORDER NO. 5-00-182 WASTE DISCHARGE REQUIREMENTS FOR R. LAWSON ENTERPRISES dba WILDROSE VINEYARDS SAN JOAQUIN COUNTY The California Regional Water Quality Control Board, Central Valley Region, (hereafter Board) finds that: 1. R. Lawson Enterprises dba WildRose Vineyards (hereafter Discharger) submitted a Report of Waste Discharge (RWD) dated 13 April 2000 to treat and dispose of wastewater generated at a winery. Additional information was submitted on 15 May 2000 and 16 June 2000. 2. R. Lawson Enterprises is a limited liability corporation and owns the property where the winery, ancillary buildings, wastewater disposal pond, and surrounding vineyard and cherry orchard are located. 3. California Fruit Processors (CFP) leases a building, yard, and wastewater pond space from R. Lawson Enterprises. CFP is a cherry briner whose activities require storage of fruit in brine solutions. Prior to CFP, Dole Fruit occupied the property. During the processing season, approximately 200 gallons per day of wastewater is discharged to a treatment system. In approximately July through November of every year, CFP discharges approximately 15 percent of the stored and treated brine water to the wastewater pond; the remainder is re-used or shipped off- site. Prior to discharge, hydrogen peroxide (HZOz) is added to the brine solution to precipitate gypsum which is then sold as a soil amendment. CFP is presently discharging wastewater under Title 27 Waste Discharge Requirements (WDRs) Order No. 92-154. The CFP wastewater discharge is to the unlined wastewater pond. These WDRs do not allow wastewater from CFP to mix with the winery wastewater. 4. In 1999,the Discharger was granted a one-year waiver of WDRs in order to monitor its wastewater quality and prepare a RWD. The Discharger failed to collect the wastewater quality data. These WDRs were prepared based on typical winery wastewater data. 5. Wastewater generated at WildRose Vineyards and CFP is commingled at the treatment system sump; however, this Order requires that the wastes be separated. Treatment consists of screening the wastewater prior to discharge. Presently, discharge is to the existing wastewater pond or cropland. 6. The winery is located on 20.9 acres (Assessor's Parcel Nos. 051-060-02, 03, 04, 40, 41 and 051-030-50, 51, 59, 63) in Section 4, T3N,R7E, MDB&M, at 8751 East Highway 12, Victor in San Joaquin County. The location of the winery facility is shown on Attachment A, which is attached hereto and is made part of this Order by reference.
