08 March 2000 <br /> AGE-NC Project No 96-0232 <br /> Page 5 of 11 <br /> of MTBE-impacted ground water, AGE proposes to advance five CPT soil borings to collect <br /> geological and ground water data The assessment activities will consist of the following tasks <br /> • Permitting and pre-field work activities, <br /> • CPT drilling and soil sample collection, <br /> • Clustered monitonng well installation and development, <br /> • Ground water sample collection, <br /> • Preparation of a report of findings <br /> 3 1 PERMITTING AND PRE-FIELD WORK ACTIVITIES <br /> Applicable site assessment permits will be obtained from the PHS-EHD In addition, an update to <br /> the health and safety plan presently on-file will be prepared in accordance with Occupational Safety <br /> and Health Guidance Manual for Hazardous Waste Site Activities (National Institute for <br /> Occupational Safety and Health Administration, U S Coast Guard and U S Environmental <br /> Protection Agency, 1985) Prior to mobilization, each monitoring well location will be clearly <br /> marked and a utility clearance obtained through Underground Service Alert <br /> 32 CPT DRILLING AND SOIL SAMPLE COLLECTION <br /> AGE proposes to drill five CPT soil borings at the site as part of site assessment activities Proposed <br /> CPT soil boring locations are illustrated in Figure 2 <br /> Based on MTBE-impact encountered during the ongoing investigation, AGE proposes CPT soil <br /> bonngs in the following locations <br /> • Between 10 and 20 feet west of ground water monitoring well MW-1 to characterize <br /> lithology, potential contaminant migration pathways and to assess the vertical extent of <br /> MTBE-impacted ground water downgradient of the UST area, <br /> • Between 10 and 20 feet east of the Rocky's Restaurant domestic drinking water well to <br /> characterize lithology, potential contaminant migration pathways and to assess the vertical <br /> extent of MTBE-impacted ground water downgradient of the UST area, <br /> • Between 40 and 50 feet north of ground water monitoring well MW-4 to characterize <br /> lithology, ground water gradient,potential contaminant migration pathways and to assess the <br /> vertical extent of MTBE-impacted ground water downgradient of the former UST area, <br /> Advanced GeoEnvironmental,Inc <br />
