PERMITTING AND PRE-FIELD WORK ACTIVITIES <br /> Applicable site assessment permits, off-site access agree e ts, and/or encroacime t permits will <br /> be obtained from the EHD.In addition,an update to the site health and safety plan presently on-file <br /> will be prepared in accordance with Occupational Safety and Health Guidance Manual for <br /> Hazardous Waste Site Activities (National Institute for Occupational Safety and Health <br /> Administration, U.S. Coast Guard and U.S. Environmental Protection Agency, 1985). Prior to <br /> mobilization, the proposed well locations will be clearly marked and a utility clearance obtained <br /> through Underground Service Alert. <br /> 2.2. MONITORING WELL INSTALLATION <br /> AGE proposes to advance four soil pilot borings at the site for the installation of four ground water <br /> monitoring wells. The following technical justification for the wells are provided: <br /> • Well MW-5 is proposed to evaluate the western extent of dissolved contamination at the <br /> location of boring B24'.1. <br /> lved MTBE and BTEX detections); <br /> 10 R -M7*6 fL7 Ar-gll2-� <br /> • Well MW-6 is proposed to evaluate the southeast extent of dissolved contamination at the <br /> location as identified by the EHD; <br /> • Well MW-7 is proposed to evaluate the northeastern extent of dissolved contamination at the <br /> location downgradient of the former UST and upgradient of the MTBE detected at boring <br /> • Well MW-8 is proposed to evaluate the dissolved contamination at the former UST location <br /> (MW-1) and perform a ground water extraction pilot test(MTBE detected). <br /> Proposed locations of the ground water monitoring and ground water extraction wells are illustrated <br /> on Figure 2. <br /> Advanced GeoEnvironmental,Inc. <br />
