Kennedy/Jenks Consultants <br /> Section 3: Field Activities <br /> 3.1 Field Preparation <br /> Field preparation includes the following: <br /> • Develop a site-specific Health and Safety Plan (HASP). The HASP for this investigation is <br /> included in Appendix A. <br /> • Obtain a boring permit from SJECHD. <br /> • Make all necessary notifications and interactions with BNSF to comply with BNSF and FRA <br /> railroad worker protection requirements. <br /> • Mark the boring locations with white paint or stakes. Underground Service Alert (USA) will <br /> be notified of sampling at least 48 hours in advance. <br /> • In addition, the potential presence of underground utilities in the proposed drilling areas will <br /> be assessed by a private contractor using non-invasive geophysical means. <br /> • The drilling contractor will also provide a vacuum truck (an "air knife' device)to uncover any <br /> utilities near the borings to verify the utilities' depth and orientation. <br /> • Subcontract with a drilling contractor licensed in California. <br /> • Arrange with a state-certified laboratory for analysis of the samples. <br /> 3.2 Soil Boring and Sample Collection <br /> 3.2.1 Soil Sample Identification <br /> As discussed in Section 2, the proposed soil boring locations are shown on Figure 2. Samples <br /> will be collected at three depths in each of the borings: 5 feet bgs, 10 feet bgs and 15 feet bgs. It <br /> is assumed that groundwater will not be encountered. <br /> Soil borings will be named with the prefix"KB" followed by a number; borings will be numbered <br /> in the order they are drilled. Soil samples will be identified according to the boring name and <br /> depth, e.g. KB-01-5 for a sample collected from the first boring at 5 feet bgs. <br /> 3.2.2 Drilling and Soil Sample Collection Methods <br /> The soil borings will be drilled and continuously cored using a hydraulic push-drive drill rig in <br /> general accordance with the Kennedy/Jenks Standard Operating Guideline (SOG) included in <br /> Appendix B. Soil borings will be drilled to a maximum depth of 15 feet bgs unless visual <br /> indications of petroleum hydrocarbon impact are noted. In these cases the borings will be <br /> deepened to 20 feet bgs. <br /> Soil Investigation Work Plan, Page 3 <br /> BNSF Mormon Yard, Stockton, California <br /> g:ll Toupladminjob113113 DM.00_bndO&epMalsoiNnveA-w A-planbddm <br />
