WASTE DISCHARGE REQUIREMENTS ORDER R5-2012-0103 - 28 - CONSTELLATION BRANDS U.S. OPERATIONS, INC. dba WOODBRIDGE WINERY WOODBRIDGE WINERY SAN JOAQUIN COUNTY 2. Crops shall be grown on the LAAs. Crops shall be selected based on nutrient uptake capacity, tolerance to soil moisture conditions, consumptive use of water, and irrigation requirements. Cropping activities shall be sufficient to take up the nitrogen and other macronutrients applied, and crops shall be harvested and removed from the land at least on an annual basis. 3. Discharge of treated wastewater, including runoff, spray or droplets from the irrigation system, shall not occur outside the boundaries of the approved LAAs. Treated wastewater application using sprinklers, flood, or drip irrigation is acceptable if the discharge complies with all requirements of this Order. 4. Discharge of storm water runoff from the LAAs and landscaped areas irrigated with wastewater is prohibited. 5. Hydraulic loading of treated wastewater and irrigation water shall be at reasonable agronomic rates designed to minimize the potential impact to groundwater quality by percolation of waste constituents below the root zone. 6. The Discharger shall use higher quality surface water from the Mokelumne River for supplemental irrigation to the maximum extent permissible under its riparian water rights. 7. Grade separations, berms, swales or ditches shall be maintained around the perimeter of the LAAs and landscaped areas irrigated with wastewater to prevent the runoff of treated wastewater or storm water. 8. Application of treated wastewater to the LAAs using sprinkler irrigation is prohibited when wind velocities exceed 30 miles per hour. 9. The LAAs shall be managed to prevent breeding of mosquitoes. More specifically: a. All applied irrigation water must infiltrate completely within 24 hours. b. Ditches not serving as wildlife habitat should be maintained free of emergent, marginal, and floating vegetation. c. Low pressure pipelines, unpressurized pipelines, and ditches that are accessible to mosquitoes shall not be used to store wastewater. 10. A 50-foot buffer zone shall be maintained between any properties developed as residences and the wetted area resulting from application of wastewater. 11. The resulting effect of the wastewater discharge on the soil pH shall not exceed the buffering capacity of the soil profile and shall not cause significant mobilization of soil constituents such as iron and manganese. 12. Effluent shall not be discharged to the LAAs when soils are saturated.
