WASTE DISCHARGE REQUIREMENORDER NO R5-2012-0106 -10. <br /> GLENN SPRINGS HOLDING COMPANY, <br /> FORMER OCCIDENTAL CHEMICAL COMPANY,GROUNDWATER REMEDIATION PROJECT, LATHROP FACILITY <br /> SAN JOAQUIN COUNTY <br /> 6. Discharge of waste at a location or in a manner different from that described in the <br /> Findings is prohibited. <br /> B. DISCHARGE SPECIFICATIONS: <br /> 1. The discharges shall remain within the designated disposal areas (injection wells) <br /> at all times, as shown on Attachment C, a part of this Order. <br /> 2. The Discharger shall not cause degradation or nuisance of any water supply as <br /> defined by the California Water Code. <br /> 3. The disposal of the treated groundwater into injection wells screened below the <br /> Corcoran Clay shall not exceed 750 gpm. The disposal of the treated groundwater <br /> above the Corcoran Clay shall not exceed 1,250 gpm. Injection flow rates shall not <br /> exceed the demonstrated treatment system capacities. <br /> 4. Total discharge from the treatment system shall not exceed 750 gpm until it is <br /> demonstrated that the proposed treatment plant capacity is greater than the current <br /> capacity. <br /> 5. The best currently approved analytical methods for DBCP have detection levels of <br /> 0.001 NgIL and practical quantitation levels of 0.01 pg/L. The practical <br /> quantification level is above the effluent limitation for DBCP. Compliance with the <br /> effluent limitation is demonstrated by measuring no detectable concentrations of <br /> DBCP when using the method(s) listed on MRP R5-2012-0106 and achieving the <br /> specified method detection limit. If new methods are approved that improve on the <br /> detection level and practical quantitation level, the MRP will be revised. <br /> 6. The discharge from the Site treatment system to the injection wells shall not <br /> contain concentrations of COCl exceeding the following effluent limits: <br /> Constituent Effluent Limit <br /> DBCP 0.0017 IL <br /> EDB 0.01 IL <br /> Sulfolane 16 /L <br /> 7. The discharge from the J.R. Simplot backup supply well wellhead treatment <br /> system shall not contain concentrations of sulfolane exceeding 16 pg/L. <br />
