CENTRAL VALLEY REGIONAL WATER QUALITY CONTROL BOARD INSPECTION REPORT DATE PREPARED: 29 September 2005 DISCHARGER: Goldstone Land Company, Bear Creek Winery LOCATION AND COUNTY: Lodi, San Joaquin County CONTACT(S): Craig Rous, Vince Westphal INSPECTION DATE: 20 September 2005 INSPECTED BY: Tim O'Brien, Mark List ACCOMPANIED BY: Craig Rous,Vince Westphal OBSERVATIONS AND COMMENTS: Staff inspected the Bear Creek Winery prior to revising the site's Waste Discharge Requirements (WDRs). No violations of the WDRs were observed and improvements to the wastewater system were noted during the inspection. The Discharger has made improvements to the land application area, dividing it into a series of checks to allow more even application of the wastewater. Turf grass was being grown in a portion of the land application area. The grass is cut and removed from the land for use as animal feed. Pomace was stored in an area north and adjacent to the winery facility. The pomace is removed prior to the onset of winter rain. The Discharger agreed to consider cropping the pomace storage area with a winter crop to take up some nutrients that likely leach from the pomace. The proposed land application areas, Vineyard Nos. 1, 2, 3, 4, 5, and 6 (see attached figure) appeared to be well established and capable of receiving wastewater. Those land application areas will be addressed in the forthcoming tentative WDRs. The Discharger has replaced sodium hydroxide with potassium hydroxide to clean storage tanks. Use of potassium hydroxide is preferable to the use of sodium hydroxide because potassium is more likely to be taken up by crops as a micronutrient. SUMMARY: No violations were observed during the inspection. Timothy R. O'Brien Engineering Geologist A roved: W:VSI bri.n Jmauinl�sr 6ehVnac Rv)A.Gnr Oi am
