Provide information on the previous land use. Provide a site map which shows property lines, buildings, treatment or storage ponds, land application areas. 2) Do active or abandoned industrial, agricultural, domestic, or groundwater wells exist on the property or the wastewater disposal area(s)? If yes,provide a map showing their location(s). Include available data on the depth of groundwater and information on aquifers and aquitards identified beneath the property. 3) Describe any ion exchange (water softening),reverse osmosis, or other treatment process for the supply water. Describe the disposal of any regeneration brine or reverse osmosis reject water. Provide a description of the process supply wastewater; at a minimum, the process supply water should be characterized for the following analytical parameters: nitrate, total Kjeldahl nitrogen, total dissolved solids, and pH. 4) Provide a list of chemicals which are used in the winemaking processes, include all chemicals used in tank, bottle, or other cleaning. Is a clean-in-place system planned for the winery? Describe the sources of hot water used in the winery. 5) Provide 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. 6) Provide information showing that the proposed method of disposal will not impact the quality of the underlying groundwater. 7) Describe the storage and disposal of stormwater. Describe the proposed criteria for switching the discharge between the stormwater ponds and the wastewater ponds, and activities that will be performed to purge the wastewater sump of industrial wastewater prior to diverting stormwater to the stormwater ponds. Describe how the criteria is protective of shallow groundwater quality, especially at the stormwater pond. 8) Describe the domestic wastewater system.

Include monthly evaporation,precipitation, stormwater run-off, and irrigation rates as well as monthly discharge volumes. Rainfall shall be based on the 100-year return period total annual precipitation. Describe all assumptions employed regarding stormwater run-off. 11) If applicable, describe measures that will be implemented to prevent groundwater from floating and damaging the pond liners. f.:Pr.nt FIIn31t.• lu4eluninv Wm'IneyrJ.U'eh.tAl'lYdYi.Jec
