�. �ftw INFORMATION SHEET ORDER NO. GOLDSTONE LAND COMPANY, LLC AND KURT KAUTZ BEAR CREEK WINERY SAN JOAQUIN COUNTY Bear Creek Winery crushes grapes, collects the juice, and ferments wine. The Discharger currently crushes approximately 30,000 tons of grapes annually and stores approximately 8 million gallons of wine for bulk distribution. No bottling is currently performed on-site. Process solid wastes (lees, pomace, and stems) are applied as a soil amendment to the vineyard. Facility History The winery has existed since 1934. Goldstone Land Company, LLC and Kurt Kautz own the Bear Creek Winery, associated vineyards, and land treatment units. Kurt Kautz owns the winery facility and land treatment units; Goldstone Land Company, LLC doing business as Bear Creek Winery, operates the facility. The winery and land treatment units (both present and proposed for the future) comprise approximately 196 acres in Lodi, San Joaquin County. The Discharger plans to increase production over the next ten years to crush 60,000 tons of grapes and reach a total capacity of 20,000,000 gallons per year. The Discharger also plans to add a bottling facility, a barrel warehouse, and a cased goods warehouse within the next ten years. The facility has a distillery, but it has not been used since 1995. The Discharger does not plan to use the distillery in the future. 4 Wastewater Generation Process wastewater is generated by the following operations: crushing/destemming, pressing,racking, fining,tank cleaning, general washdown, process equipment sterilization, cold stabilization, and protein stabilization. Wastewater is also generated when storm water falls on outdoor processing and storage areas. All collected site stormwater is piped to a pumping station where it is mixed with process wastewater and applied to land. During wine storage and distribution, various chemicals are used, primarily as cleaners or sanitizers. The facility currently does not have a flow meter. The Discharger estimates that flows range from 100,000 gallons per month(3,300 gpd) to 6.3 million gallons per month (210,000 gpd). Wastewater flow rates are highest during and after the crush season (August through December). Three ion exchange water softeners exist at the site; one wine ion exchange unit also exists. The ion exchange water softeners are reportedly infrequently used but can be used in the future. Regeneration brine is discharged to the wastewater system. The wine ion exchange unit, which is used to adjust the pH of the wine, is charged with sulfuric acid. The acid rinsate is neutralized with caustic soda or soda ash before discharge to the wastewater system. Wastewater Treatment The Discharger is proposing to collect, screen, and discharge the wastewater to the LTUs without treatment. Because the pH of the wastewater can experience significant changes depending on activities in the winery, and there is no equalization basin for pH to neutralize prior to discharge, the Discharger is required to neutralize pH prior to discharge to the LTUs. This is considered important to protect crop health and microbial populations that will treat the waste in the LTUs.
