WASTE DISCHARGE REQUIRN,.iNTS ORDER NO. 1.d -13- GOLDSTONE LAND COMPANY,LLC AND KURT KAUTZ BEAR CREEK WINERY SAN JOAQUIN COUNTY Winery Background Analyte Units Wastewater Groundwater2 Limits Chloride Mg/L 3-250 33 33 Sodium Mg/L 35-200 55.5 56 TDS Mg/L 80-2,900 671 671 Nitrate as N Mg/L 0.5-4.83 22.7 10 J The average for both crush and non-crush sdasons. 2 Background quality defined by the average concentrations of samples from Well MW-2. a Organic nitrogen compounds can vary from I to 40 mg/1. 67. The discharge is nonhazardous, but exhibits characteristics of"designated waste,"as the concentrations of some waste constituents when treated, stored, and applied to land have potential for causing exceedances of water quality objectives or adversely affecting beneficial uses. The discharge contains decomposable waste constituents (e.g., organic carbon and nutrient compounds) and inorganic dissolved solids in concentrations that are greater than water quality objectives. 68. The discharge must be categorized as designated waste because of these constituents and subjected to the full containment provisions of Title 27 unless it can be demonstrated that constituents of concern, afterrelease, are effectively and consistently removed by attenuation in the soil profile and the discharge fully compliant with the Basin Plan. For waste applied to the land application area, it means a demonstration that controlled land treatment removes waste decomposable constituents within the LTU and, for those not totally decomposable,passes through concentrations that will cause no degradation of groundwater. 69. The waste that is discharged to land contains TDS well in excess of governing background quality and these constituents are not effectively removed by the LTU. The practical demonstration of removal of dissolved solids as projected by the Discharger has not been demonstrated as required for an LTU. The Discharger has not established the design LTU depth that is dependent upon crop. The Discharger has not established an evaluation monitoring program,unsaturated zone monitoring program, or water quality protection standards for each waste constituent. Inorganic dissolved solids can be effectively controlled by means of source control, treatment, or containment. Source control includes best management practices of selective and judicious chemical use (e.g., potassium-based cleaning solutions instead of sodium-based) and waste stream isolation or segregation where possible(in particular separate handling of high strength wastewater, ion exchange regeneration brine, and boiler blowdown). Treatment technology includes reverse osmosis and ion exchange applied to the wastewater, but we have no evidence that any have been evaluated or applied to the discharge. Containment technology includes Title 27 prescriptive standards where appropriate,but there is no evidence that these were considered for implementation for all applicable waste streams. 70. The Discharger has not proposed a project that will ensure no degradation for constituents that already exceed water quality objectives and therefore the project is inconsistent with the Basin Plan and cannot be exempted from Title 27 standards.
