Ms. Margaret Lagorio <br /> October 6, 1995 <br /> Page 2 <br /> flatbed truck and is powered by an onboard generator that provides the electrical power (110 volts <br /> AC) to operate sampling pumps, a steam cleaner, and other field equipment. <br /> The DPS 550 rig consists of a hydraulic probe installation and removal device mounted on the <br /> back of the flatbed truck. The system employs a 550 pound hydraulic hammer and a driving- <br /> removal ram that can generate 100,000 pounds of force. The probes consist of 10-foot sections <br /> of 2.5 inch OD drill steel. These probes can be driven to depths of up to 80 feet bgs in order to <br /> sample without generating cuttings. <br /> Samples will be screened on-site using a mobile laboratory for the following compounds: <br /> • 1,1 dichloroethene (1,1- DCE) <br /> • TCA <br /> • TCE <br /> • PCE <br /> Any soil samples collected from the site will be sent to a fixed laboratory for analysis. <br /> Decontamination Procedures <br /> All sampling equipment will be decontaminated between each sample location. The sample <br /> collection equipment will be cleaned in a solution containing TSP or Alconox, detergent, and <br /> clean tap water and will be rinsed with de-ionized or distilled water. All waste decontamination <br /> solutions will be contained in D.O.T.-approved containers for temporary on-site storage pending <br /> determination of disposal options. <br /> Health & Safety Procedures <br /> All field activities will be conducted under a site specific Health & Safety Plan (HASP) prepared <br /> in accordance with regulations set forth in 40 CFR 1919.120. Procedures for conducting work <br /> safely at the site are outlined in the HASP. The HASP includes the following major components: <br /> • general project and personnel information; <br /> • facility/site information; <br /> • project work plan; <br /> • task and chemical specific safety and health risk analysis; <br /> • site health and safety operating procedures; and <br /> • contingency plan. <br /> L\3P_AMER\RC951466.WP <br /> 10.06.95 <br /> jw caren° <br /> FM HIt <br /> ENVIRONMENTAL ENGINEERING CORPORATION <br /> .ecyGeo oaaw <br />
