Groundwater VOC and Fuel General Permit ORDER NO.R2-2012-0012 <br /> NPDES NO.CAG912002 <br /> E. The sample may be taken from effluent prior to chlorination. Monitoring of the bioassay water <br /> shall include, on a daily basis, the following parameters: pH, dissolved oxygen, ammonia, (if <br /> toxicity is observed),temperature, hardness, and alkalinity. These results shall be reported. If a <br /> violation of acute toxicity requirements occurs, the bioassay test shall be repeated with new fish <br /> as soon as practical and shall be repeated until a test fish survival rate of 90 percent or greater is <br /> observed. If the control fish survival rate is less than 90 percent, the bioassay test shall be <br /> restarted with new fish and shall continue as soon as practical until an acceptable test is <br /> completed(i.e., control fish survival rate is 90 percent or greater). <br /> VI. RECLAMATION MONITORING REQUIREMENTS <br /> The Discharger shall monitor reuse effluent at Monitoring Location REU-001 as shown on Column 2 of <br /> Table E.2. <br /> VII. RECEIVING WATER MONITORING REQUIREMENTS—SURFACE WATER AND <br /> GROUNDWATER <br /> The Discharger shall monitor receiving water at Monitoring Locations RSW-OOlU and RSW-OOlD as <br /> shown on Column 3 of Table E.2. <br /> A. Receiving water sampling shall occur concurrently with effluent sampling. <br /> B. Receiving water samples shall be collected at each station on each sampling day during the <br /> period within 1 hour following low slack water, if relevant. Where sampling at lower slack water <br /> period is not practical, sampling shall be performed during higher slack water period. Samples <br /> shall be collected within the discharge plume and 50 feet down current of the discharge point so <br /> as to be representative,unless otherwise stipulated. <br /> C. Samples should be collected within one foot below the surface of the receiving water body. <br /> Explanation shall be provided in the monitoring report if this specification could not be met. <br /> Table E-2.
