WASTE DISCHARGE REQUIREMENTS ORDER NO.R5-2002-0225 ALPINE PACKING COMPANY,INC. 11 WASTEWATER TREATMENT SYSTEM, SAN JOAQUIN COUNTY d. Specific standards are prescribed by which to monitor water quality(§20420), including a detection monitoring program (§20420), an evaluation monitoring program (§20425), and an unsaturated zone monitoring program for the LTU(§20435), which requires soil-pore liquid monitoring to ensure effective operation. 62. Pursuant to §20090(b), the Board may exempt a discharge from Title 27 only if: a. The Regional Board issues waste discharge requirements; b. The waste discharge requirements implement the Basin Plan and allow discharge only in accordance with the Basin Plan; and c. The wastewater is nonhazardous waste and need not be managed according to Title 22, CCR, Division 4.5, Chapter 11, as a hazardous waste. ANTI-DEGRADATION ANALYSIS 63. State Water Resources Control Board (State Board) Resolution No. 68-16 (hereafter Resolution No. 68-16) requires that waste be discharged in a manner that maintains the high quality waters of the state. Any change in quality can occur only after full application of best practicable treatment and control (BPTC) of the waste, and must be consistent with maximum benefit to the people of the State, not unreasonably affect a beneficial use, and not result in water that exceeds a water quality objective. Where the water quality objective is exceeded in background water quality but nonetheless beneficially used or designated for beneficial use, the background water quality cannot be degraded. 64. Antidegradation factors have been considered pursuant to Resolution No. 68-16. At this time, it is unknown whether the project as proposed will degrade groundwater with dissolved solids and/or organics, or create nuisance odors from organics while waste is ponded and in the manner applied to land. Degradation of the groundwater with organics and/or dissolved solids is not consistent with maximum benefit to the people of the State. If it were, the Discharger would have to demonstrate its treatment as being best practicable treatment and control (BPTC). The Discharger has made no BPTC demonstration. At this time, the project as proposed by the Discharger is consistent with Resolution 68-16. However, once background groundwater quality is fully evaluated, staff will review the data to determine whether the discharge is degrading the groundwater. If it is, the Discharger will be required to modify the discharge such that there is no degradation, comply with Resolution 68-16, or apply for coverage under Title 27 of the CCR. GROUNDWATER DISCHARGE ANALYSIS--LAWS,RULES, AND REGULATIONS 65. For the waste constituents present in the discharge in significant concentrations, the water quality objectives determined by the translator process from narrative objectives are all higher than the observed background water quality, except for TDS. Where background water quality is unaffected by other discharges and greater than water quality objectives, the background water quality establishes the water quality limit. Within the San Joaquin Valley, the salinity of the groundwater has been degraded through years of agricultural operations. At this facility, there does not appear to be a direct upgradient source of the salinity; therefore, the background water quality value for TDS
