INFORMATION SHEET 4 <br /> WASTE DISCHARGE REQUIREMENTS ORDER NO.R5-2004-XXXX <br /> DEFENSE DISTRIBUTION DEPOT SAN JOAQUIN <br /> SHARPE WASTEWATER TREATMENT FACILITY <br /> SAN JOAQUIN COUNTY <br /> occur from certain constituents, but can never exceed water quality objectives (or <br /> background water quality should it exceed objectives) or cause nuisance. <br /> Water quality objectives define the least stringent limits that could apply as water quality <br /> limitations for groundwater at this location, except where natural background quality <br /> unaffected by the discharge already exceeds the objective. The values below are <br /> concentrations directly from the Basin Plan, or derived indirectly using Basin Plan <br /> procedures for implementation of narrative water quality objectives, and must be met to <br /> maintain specific beneficial uses of groundwater. They are based on numeric and <br /> narrative water quality objectives. Consistent with the Policy for Application of Water <br /> Quality Objectives in the Basin Plan, criteria of appropriate agencies have been used to <br /> implement narrative water quality objectives. Unless natural background for a <br /> constituent proves higher, the interim groundwater quality limitations established in the <br /> proposed Order is the most stringent of the values listed for the constituents below. <br /> Constituent Units Value Beneficial Criteria or Justification <br /> Use <br /> Ammonia mg/L 1.5 MUN ' Taste and Odor 2 <br /> Boron mg/L 0.7 AGR' Boron Sensitivity 4 <br /> mg/L 1.0 MUNI Calif.
