)!TONAL INFORMATION REQIENTS BEAR CREEK WINERY LODI,SAN JOAQUIN COUNTY 1) Provide a flow diagram of the wastewater generation and treatment system. Include a map showing the locations of all treatment equipment, clarifiers, sumps, or pump stations. Describe procedures to control contaminants in the wastewater streams and in the wastewater ponds. 2) Describe the existing and proposed wastewater disposal system, all land application areas, and any changes that you are proposing. Show the locations of all existing/proposed land application areas on a topographic map. Staff is concerned that the low level of treatment prior to discharge will result in inadequately treated wastewater commingling with stormwater which then migrates out of the land application areas. Please address this issue. 3) If surface impoundments will be used to store wastewater or regeneration brine, provide diagrams and a description of the planned impoundment, location, size and depth, construction materials, inlet and outlets, depth to groundwater below the bottom of the pond, and existing or planned groundwater monitoring wells. If stormwater ponds exist,have they ever overflowed? 4) Allowing for two feet of freeboard, what is the approximate storage capacity of any planned wastewater ponds? Provide a water balance that evaluates the containment structures ability to provide sufficient capacity on a month by month basis. Include monthly evaporation, precipitation, and irrigation rates as well as monthly discharge volumes. Rainfall shall be based on the 100-year return period total annual precipitation. 5) Please resubmit the loading calculations using both crush and non-crush flow rates and contaminant concentrations. Present loading rates for BOD (in lbs/acre-day), total nitrogen(in lbs/acre-year), and dissolved solids (in lbs/acre-year). Provide a description of the disposal areas and the disposal technique. State the number of acres of land used for disposal and crops planned for application areas (show locations of land on map). Describe harvesting and crop disposal procedures. Describe the mixing ratio of wastewater and supplemental irrigation water prior to application, and describe the tailwater control and return system. (Note: Discharge of wastewater to fallow land is not an acceptable method of disposal). 6) Describe the existing wastewater disposal system, and any changes that you are proposing. If possible, show that this method of disposal will not impact the quality of the underlying groundwater otherwise, describe proposed changes to the system. 11/19/2001 c.wnM fawvew..c�w�ww.k
