I31 August 2000 <br /> AGE Project No 96-0232 <br /> Page 22 of 25 <br /> I6.0. PROCEDURES <br /> All field procedures will be overseen by an AGE representative under the supervision of a Califomra <br /> Registered Geologist Procedures for ground water extraction well installation, underground piping <br /> system Installation,pump and treat system start-up period, sampling, monitoring, maintenance and <br /> progress/confirmation sampling are outlined below <br /> 61 DRILLING ACTIVITIES <br /> The following Procedures will be performed prior to any digging/drillingactivities <br /> a Prepare a Site Health and Safety Plan In accordance with the Occupational Safety and Health <br /> Guidance Manual for Hazardous Waste Site Activities - Prepared by National Institute for <br /> Occupational Safety and Health, Occupational Safety and Health Administration, U S Coast <br /> Guard and U S Environmental Protection Agency, October 1985 <br /> Notify the RWQCB and PHS-EHD a minimum of 48 hours prior to commencement of any <br />� . work, while securing proper soil boring or well installation permits <br /> a All drilling locations will be marked at least 48 hours in advance for an Underground Service <br /> Alert (USA) check of underground utilities or pipes <br /> 62 SYSTEM DESIGN <br /> Ground water will be extracted from well EW-2 and seven newly installed ground water extraction <br /> wells (Figure 3) utilizing submersible, 4-inch diameter Grundfos self-priming downhole pumps <br /> Each pump which will be outfitted with automated electronic shut-off controls to control water <br /> entering the system AGE anticipates total ground water extraction flow between 20 and 25 GPM,' <br /> therefore a surge pumping technique will be implemented at each well head to control the volume <br /> of produced water During the pumping operation, the estimated ground water extraction flow rate <br /> will be between five and sax GPM at each well head <br /> From each well head, extracted ground water will be routed through a sediment pre-filter and into <br /> a 750-gallon holding tank, from winch it will pass through a process pump, a bag filter with gauges <br /> on to the first GAC vessel and subsequently the second and third GAC vessels Again,the GAC units <br /> are designed to adsorb as much gasoline compounds as possible prior to introduction into the Sun <br /> Solve vessels Following the GAC treatment, the water will be routed through three vessels of Sun <br /> Solve, which are connected in series The Sun Solve is intended specifically to adsorb MTBE <br /> Sample ports will be located an appropriate positions between and after the GAC and Sun Solve <br /> I <br /> Advanced GeoEnvironmental,Inc <br />
