Michelle Price,City of Stockton May 1,2014 <br /> Application to Discharge Extracted Groundwater to the Sanitary Sewer <br /> Quick-N-Save#2 Stockton,CA <br /> Page 3 <br /> from the temporary holding tank. The effluent sample will be analyzed for total toxic <br /> organics (TTO) per 40 CFR 413 constituent list by United States Environmental <br /> Protection Agency (EPA) Methods 624 and 625, gasoline range organics (GRO), <br /> benzene, toluene, ethylbenzene, and xylenes (BTEX compounds), methyl tertiary butyl <br /> ether (MTBE), tertiary butyl alcohol (TBA) using SW8015B/SW8260B, and lead using <br /> USEPA Method 200.8, unless required otherwise by the City of Stockton's discharge <br /> permit. The pH levels will be obtained in the field. The remaining interim influent, <br /> midfluent and effluent samples obtained throughout the duration of the event will be <br /> collected and analyzed on a monthly basis for GRO, BTEX and MTBE to evaluate <br /> system performance and monitor the contaminant mass extraction rate. <br /> During each site visit, a Stratus technician will complete the following: <br /> • Record total flow of groundwater into the system, <br /> • Record rate of discharge to the sanitary sewer and cumulative discharge total, <br /> • Collect influent, midfluent, and effluent water samples for laboratory <br /> analyses, <br /> • Check system performance, <br /> • Record system running and down times. <br /> Upon completion of the remediation event, Stratus will prepare and submit to the City of <br /> Stockton, a notice of completion including the total volume of groundwater discharged to <br /> the sanitary sewer. As necessary, Stratus will forward the City of Stockton copies of all <br /> analytical reports along with the appropriate chain of custody documentation. <br /> If you have any questions or comments, please call Deborah L.
