WASTE DISCHARGE REQUIREMENTS ORDER NO. 5-00-182 -2-
<br /> R.LAWSON ENTERPRISES DBA WILDROSE VINEYARDS
<br /> SAN JOAQUIN COUNTY
<br /> 7. Activities at the winery include receiving, crushing and pressing of grapes, fermentation,
<br /> processing into finished wines, and distribution. A bottling line is planned for the future.
<br /> Wastewater from tank cleaning, grape crushing, stormwater, defrost water, and equipment/floor
<br /> cleaning water are discharged to the wastewater treatment system. However, the Discharger is
<br /> planning site improvements which will separate stormwater and tank defrost water from the winery
<br /> wastewater flow. A site map is presented on Attachment B, which is attached hereto and made part
<br /> of this Order by reference.
<br /> 8. The Discharger estimated wastewater flow rates for tank wash water(1,500 gal/month), defrost
<br /> water(33,000 gal/month, generated only three months per year), and grape crush:cleaning water
<br /> (3,000 gal/month, generated only three months per year).
<br /> 9. Winery wastewater flow is not individually metered. Due to a meter failure, flow rates for the
<br /> crush season are not available. Planned expansions and new site activities will result in increased
<br /> flow rates. Presently, flows are not adequately metered; these waste discharge requirements
<br /> include a provision for installation of a meter to determine the wastewater flow rate. Total flow
<br /> rates (WildRose, CFP, and stormwater) measured in 1999 are presented below:
<br /> Month Flow Rate (god) Comment
<br /> January, 1999 7,522
<br /> February, 1999 17,100
<br /> March, 1999 12,926
<br /> April, 1999 8,290
<br /> May, 1999 3,070
<br /> June, 1999 2,230
<br /> July, 1999 3,960
<br /> August, 1999 8,670
<br /> September, 1999 9,000 Estimate,meter broken
<br /> October, 1999 9,000 Estimate, meter broken
<br /> November, 1999 8,920
<br /> December, 1999 8,728
<br /> Data from WildRose Report of Waste Discharge.
<br /> 10. Stormwater which falls on buildings or paved areas of the Discharger's facility is presently directed
<br /> into stormwater drains and is discharged to the wastewater treatment system. The Discharger is
<br /> planning to separate the stormwater from the treatment system flow.
<br /> 11. Winery wastewaters (except defrost water) are screened at floor drains and flow through a two-
<br /> stage clarifier. Screenings and settleable materials are collected and disposed in trash dumpsters.
<br /> Presently, defrost water is piped into the wastewater flow downstream of the clarifier and upstream
<br /> of the treatment system. The Discharger is planning to separate the defrost water flow from the
<br /> treatment system.
