11 January 2007 AGE-NC Project No. 00-0769 Page 2 of 8 2 . 1 . PERMITTING AND PRE-FIELD WORK ACTIVITIES Applicable well installation permits will be obtained from the EHD prior to drilling activities. Encroachment permits, if necessary, will be obtained from the City of Stockton. Additionally, a discharge permit for treated ground water will be obtained from the City of Stockton Public Works. As required by EHD permitting, a health and safety plan will be prepared in accordance with Occupational Safety and Health Guidance Manual for Hazardous Waste Site Activities (National Institute for Occupational Safety and Health Administration, U. S. Coast Guard and U.S . Environmental Protection Agency, 1985). Prior to mobilization, the soil probe location will be clearly marked and a utility clearance obtained through Underground Service Alert. 2.2. SOIL BORING AND EXTRACTION WELL INSTALLATION Initially, AGE proposes to advance four soil borings on-site for the collection of soil samples as part of assessment activities. The borings will be utilized for the installation of single-completion extraction wells. The proposed well locations are illustrated in Figure 2. The scope of work for the advancement of soil borings and well installations includes the following: • One shallow boring will be advanced near monitoring well MW-5 . The boring will be completed as a ground water extraction well for interim remediation of the core area of contamination at UST #3 ; • One shallow boring will be advanced near monitoring well MW-4. The boring will be completed as a ground water extraction well for the interim remediation of the core area of contamination at UST #1 and UST #2; • One shallow boring will be advanced near monitoring well MW-3 . The boring will be completed as a ground water extraction well for the interim remediation of the core area of contamination at UST #1 and UST #2 ; • One deep boring will be advanced between monitoring wells MW-3 and MW-4. The boring will be completed as a ground water extraction well for the interim remediation of the core area of deep contamination at UST #1 and UST #2. During the drilling of the proposed boring, soil samples will be collected at five-foot intervals from ground surface to the total depth of the borings. Field procedures for the collection of soil samples are presented in Section 3 . 1 . 1 . At least two soil samples from each soil boring will be analyzed for; Advanced GeoEnvironmental, Inc.
