21 March 2003 <br /> AGE-NC Project No. 95-0114 <br /> Page 5of11 <br /> r Advancement of pilot borings for multi-level monitoring wells, and soil sample collection <br /> and analysis; <br /> • `Multi-level' monitoring well installation, development, sampling and analysis; <br /> • Probe boring advancement and soil-gas sample collection and analysis; and <br /> • Report preparation. <br /> 3.1. PERMITTING AND PRE-FIELD WORK ACTIVITIES <br /> Applicable site assessment permits will be obtained from the San Joaquin County Environmental <br /> Health Department(EHD);in addition,AGE will obtain any necessary encroachment permits from <br /> the City of Stockton, access agreements from private property owners and the Stockton Unified <br /> School District (SUSD) to assess on their properties. <br /> As required by EHD permitting, a health and safety plan will be prepared in accordance with <br /> Occupational Safety and Health Guidance Manual for Hazardous Waste Site Activities (National <br /> Institute for Occupational Safety and Health Administration and U.S. Environmental Protection <br /> Agency, 1985). Prior to mobilization, each soil probe location will be clearly marked and a utility <br /> clearance obtained through Underground Service Alert. <br /> 3.2. PILOT BORING AND MONITORING WELL INSTALLATION <br /> Based on CPT,monitoring well and soil boring data,AGE proposes to advance four soil borings on- <br /> and off-site for the collection of soil samples and the installation of multi-level ground water <br /> monitoring wells (Figure 2): <br /> • One soil boring advanced on-site to approximately 150 feet bsg at the former UST cluster <br /> for installation of a multi-level monitoring well to determine the vertical extent of <br /> hydrocarbon-impacted ground water. <br /> • One soil boring advanced at the southeast corner of Harding Way and Monroe Street for <br /> installation a of multi-level monitoring well to determine the eastern lateral extent as well <br /> as vertical extent of hydrocarbon-impacted ground water. <br /> • Two soil borings advanced at the location of MW-10 and east of CPT6 for installation of <br /> multi-level monitoring wells to monitor and define the north-eastern lateral and vertical <br /> extent of hydrocarbon-impacted ground water. <br /> Advanced GeoEnvironmental,Inc. <br />
