01 July 2008 <br /> AGE-NC Project No. 97-0301 <br /> Page 4 of 8 <br /> analysis. Total depths of borings may vary according to geologic conditions encountered during <br /> drilling. The proposed SVE wells will be advanced utilizing a truck-mounted, hollow stem drill rig <br /> equipped with 10-inch diameter hollow-stem augers. <br /> 2.4. SVE PILOT TESTS <br /> An initial 8-hour SVE pilot test will be conducted at the site. The SVE pilot test will be performed <br /> to provide induced vapor extraction data from the proposed SVE well screens (VW- 1 , VW-2 and <br /> VW-3) along with the current monitoring wells MW-6 and MW-7 for evaluation of SVE as a <br /> remedial alternative for this site and/or for the proper design of an SVE remediation system. The <br /> SVE pilot test specifications are presented in Section 3 .4. <br /> 2.5 . REPORT PREPARATION <br /> Results of the well installations and SVE pilot test will be presented in a report of findings; based <br /> on the results of the SVE pilot test, a determination will be made whether or not SVE is a feasible <br /> option at the Pacific Pride South El Dorado site; if SVE is determined to be feasible and cost <br /> effective, then AGE will propose a remediation system design in a Corrective Action Plan (CAP); <br /> the CAP will report the above findings for the SVE pilot test. The SVE pilot test report of findings <br /> and/or CAP will be in a format acceptable to the RWQCB (Appendix A guidelines), and will be <br /> reviewed and signed by a California Professional Geologist, <br /> 3.0. FIELD PROCEDURES <br /> All field procedures will be overseen by an AGE representative under the supervision of a California <br /> Professional Geologist. Procedures for ground water monitoring well, SVE well installation andpilot <br /> test procedures are described below. <br /> 3 . 1 . DRILLING <br /> Soil borings will be advanced utilizing a truck-mounted, hollow-stem drill rig and either 8-inch or <br /> 104nch diameter hollow-stem augers. Cuttings and rinseate generated during drilling activities will <br /> be containerized in properly labeled Department of Transportation (D. O .T.)-approved 55 -gallon <br /> drums, and stored on-site in an area lacking public access. Disposal alternatives will be evaluated <br /> based on results of soil analysis. <br /> Advanced GeoEnvironmental, Inc. <br />
