31 August 2000 <br /> AGE Project No 96-0232 <br /> Page 25 of 25 <br /> 50 feet bsg Probe boring will be advanced using a Geoprobe 5400 soil probing unit <br /> Discrete soil samples will be collected at five-foot intervals beginning at a depth of 5 feet bsg <br /> utilizing a Geoprobe soil sampling assembly loaded with pre-cleaned 1 125-inch by 6-inch brass <br /> sleeves Soil and grab ground water samples will be preserved by covering both ends of the second <br /> brass sleeve with Teflon sheets, plastic end caps and sealed with tape Each sample sleeve will be <br /> labeled with the followmg unfarmation soil probe boring location, depth, time, date and sampler's <br /> initials Soil samples will be transported in a cooler under ice to a DHS-certified laboratory for <br /> analysis of TPH-g, BTEX,MTBE,DIPE, TAME,ETBE and TBA in accordance with EPA methods <br /> 8015m, 8020 and 8260 <br /> 7.0. EQUIPMENT AND OPERATIONAL SAFETY <br /> The proposed pump and treat system will be equipped with an automatic shut-down valves to <br />' prevent any spillage and overflow from the treatment system This remediation action will be <br /> supervised by geologists/engineers trained to perform and supervise investigations and remedial <br /> • actions at hazardous waste sites as specified in the OSHA Hazardous Waste Operations and <br /> Emergency Response Standard(29 CFR 1910 120 (e)) The maintenance of the thermal or catalytic <br /> oxidizer unit will be performed by factory-trained technicians <br /> The treatment system will be surrounded by a lockable enclosure to protect the system from <br /> tampering by unauthorized personnel A non-smoking area of 20 feet radius will be established and <br /> posted A Site Health and Safety Plan in accordance with the Occupational Safety and Health <br /> Guidance Manual for Hazardous Waste Site Activities will be kept in the gated enclosure <br /> Advanced GeoEnv:ronmental,Iic <br />
