WASTE DISCHARGE REQUIRE;MTS ORDER NO. 5-01-172 • 6 <br /> EAST-SIDE WINERY DBA OAK MGE VINEYARDS <br /> SAN JOAQUIN COUNTY <br /> Compound Units Concentrations <br /> BODS mg/1 401/80' <br /> TDS mg/l 4502 <br /> Nitrate as Nitrogen mg/1 103 <br /> Sulfate mg/1 2504 <br /> I Technological standards easily achieved with proper design and operation <br /> 2 Agricultural Water Quality Goal <br /> 3 Primary MCL(as nitrogen) <br /> 4 Recommended upper level for Secondary MCL. <br /> 35. Excessive application of food processing wastewater to land application areas can create <br /> objectionable odors, soil conditions that are harmful to crops, and degradation of underlying <br /> groundwater by overloading the shallow soil profile and causing pollutants (organic carbon, nitrate, <br /> other salts, and metals) to percolate below the root zone. If sufficient information becomes <br /> available, this Order may be revised to increase or further reduce loading rates as appropriate. If the <br /> Discharger is unable to modify its waste stream or disposal methods such that groundwater quality <br /> will not be impacted, then the Board would be required to classify the waste as a designated waste <br /> and require full containment under Title 27 of the California Code of Regulations (hereafter <br /> Title 27). <br /> 36. State regulations pertaining to water quality monitoring for waste management units are found in <br /> Title 27, California Code of Regulations (CCR), Section 20380 et seq., (hereafter Title 27). These <br /> regulations prescribe procedures for detecting and characterizing the impact of waste constituents <br /> on groundwater. While the facility has been found exempt from Title 27, the data analysis methods <br /> of Title 27 are appropriate for determining whether the discharge complies with the terms for <br /> protection of groundwater specified in this Order. <br /> 37. According to Pollution Abatement in the Fruit and Vegetable Industry,published by the United <br /> States Environmental Protection Agency(US EPA Publication No. 625/3-77-0007) (hereafter <br /> Pollution Abatement), in applying food-processing wastewater to land for biological treatment, the <br /> loading of BODS should not exceed 100 lbs/acre-day(average) to prevent development of nuisance <br /> conditions. <br /> 38. Acidic soil conditions can be detrimental to land treatment system function, and may also cause <br /> groundwater degradation. If the buffering capacity of the soil is exceeded and soil pH decreases <br /> below 5, naturally occurring metals (including iron and manganese) may dissolve and degrade <br /> underlying groundwater. Pollution Abatement recommends that water applied to crops have a pH <br /> within 6.4 to 8.4 to protect crops from damage by food processing wastewater. Near-neutral pH is <br /> also required to maintain adequate active microbial populations in the soil. <br /> 39. Pursuant to California Water Code Section 13263(8), discharge is a privilege, not a right; and <br /> issuance of this Order does not create a vested right to continue the discharge. Failure to provide <br /> the level of management required to assure best practicable treatment and control; preclude <br /> conditions that threaten pollution or nuisance; and protect groundwater quality will be sufficient <br />
