' Work Plan-Soil and Groundwater Investigation <br /> Hennas&Helen's Marina <br /> May 30, 1995 <br /> Page-2- <br /> not encountered during the UST removal. Six (6) soil samples were collected by Condor from the <br /> UST excavation at depths of 9 to 12 feet below the ground surface (bgs). The samples were analyzed <br /> for TPH-G (gasoline), BTEX, TEPH (diesel), EDB (ethylene dibromide), and total lead. Laboratory <br /> ' analyses indicated elevated concentrations of TPH-G, TEPH, and BTEX constituents in the soil <br /> samples. For additional information, refer to Tank Pull Testing Results, prepared by Condor, dated <br /> ' November 18, 1991. <br /> ' 3.0 PROPOSED SCOPE OF WORK <br /> This section includes a description of the proposed site preparation, hydropunch drilling, <br /> sampling, laboratory analysis, and reporting. <br /> 3.1 Site Preparation <br /> ' Prior to the fieldwork, authorization will be obtained from Reclamation District #2029 for the <br /> drilling to be conducted on the levee. Adjustments will be made to the scope-of-work, as needed, to <br /> ' satisfy the Reclamation District requirements. <br /> Upon receipt of authorization from the Reclamation District, drilling permits will be obtained <br /> from the SJCEHD. The proposed drilling locations will be marked with white paint and Underground <br /> ' Service Alert (USA) will be notified at least 72 hours in advance of the fieldwork to locate and <br /> identify underground utilities in and near the work area. The SJCEHD, the Reclamation District, and <br /> ' the California Regional Water Quality Control Board (CRWQCB)will be notified of the fieldwork <br /> schedule at least 48 hours in advance. No drilling will take place in the levee during times that the <br /> ' Reclamation District feels the tides may create a dangerous condition. <br /> ' 3.2 Drilling Procedures <br /> The hydropunch boreholes will be drilled by B&F Drilling of Rancho Cordova, California <br /> ' (C57 license #519428). A Condor geologist will be on site to supervise the drilling, soil sampling, <br /> and groundwater sampling. The proposed hydropunch drilling locations are shown on Figure 2, Site <br /> ' Map. Prior to commencement of fieldwork, a tailgate safety meeting will be held and a site-specific <br /> Health and Safety Plan will be discussed with, and presented to, all crew members for their signatures. <br /> A copy of the Health and Safety Plan is contained in the Appendix of this document. <br /> Lir CONDOR <br />
