WASTE DISCHARGE REQUIRL..ENTS ORDER NO. 6 LINNE ESTATES, LLC LINNE ESTATES WASTEWATER TREATMENT SYSTEM SAN JOAQUIN COUNTY 38. The Basin Plan contains narrative water quality objectives for Chemical Constituents, Tastes and Odors, and Toxicity. The Toxicity objective, in summary, requires that groundwater be maintained free of toxic substances in concentrations that produce detrimental physiological responses in human, plant, animal, or aquatic life associated with designated beneficial uses. The Chemical Constituents objective requires that groundwater"shall not contain chemical constituents in concentrations that adversely affect beneficial uses." The Tastes and Odors objective requires that groundwater"shall not contain taste- or odor-producing substances in concentrations that cause nuisance or adversely affect beneficial uses." Chapter IV, Implementation, of the Basin Plan contains the "Policy for Application of Water Quality Objectives." This Policy specifies, in part, that compliance with narrative water quality objectives may be evaluated considering numerical criteria and guidelines developed and/or published by other agencies and organizations. 39. CWC Section 13241 requires the Regional Board to consider various factors, including economic considerations, when adopting water quality objectives into its Basin Plan. CWC Section 13263 requires the Regional Board to address the factors in Section 13241 in adopting waste discharge requirements. The State Board, however, has held that a Regional Board need not specifically address the Section 13241 factors when implementing existing water quality objectives in waste discharge requirements because the factors were already considered in adopting water quality objectives. The interim groundwater limitations implement adopted water quality objectives in the manner prescribed by the Basin Plan. No additional analysis of Section 13241 factors is required. 40. The beneficial uses of the San Joaquin Delta are municipal and domestic supply; agricultural supply; industrial process supply; industrial service supply;water contact recreation; noncontact water recreation; warm freshwater habitat, cold freshwater habitat; migration of aquatic organisms; spawning, reproduction, and/or early development; wildlife habitat; and navigation. 41. The beneficial uses of underlying groundwaters are municipal and domestic supply, industrial service supply, industrial process supply, and agricultural supply. Groundwater Degradation 42. State Board Resolution No. 68-16 ("Statement of Policy with Respect to Maintaining High Quality of Waters of the State") (hereafter Resolution No. 68-16)requires the Regional Board in regulating the discharge of waste to maintain high quality waters of the state until it is demonstrated that any change in quality will be consistent with maximum benefit to the people of the State, will not unreasonably affect beneficial uses, and will not result in water quality less than that described in the Regional Board's policies (e.g., quality that that does not conform to water quality objectives). In addition,Resolution No. 68-16 requires that discharges of waste to existing high quality waters "be required to meet waste discharge requirements which will result in the best practicable treatment or control of the discharge necessary to assure that(a)pollution or nuisance will not occur and (b)the highest water quality consistent with maximum benefit to the people of the State will be maintained."
