Kennedy/Jenks Consultants <br />Soil and groundwater sample collection is not planned, however, conditions may warrant <br />collection of samples. If soil samples are collected, a separate borehole will be drilled at each <br />location using the hydraulic push-drive system. Sample tubing will be advanced using 2- or <br />3-inch outer diameter (OD) steel rods where the lead rod is fitted with a new acetate liner. The <br />soil core is collected in the acetate liner as the rods are advanced in 4-foot or 5-foot increments. <br />The desired sample interval is cut from the acetate liner when it is retrieved. Discrete soil <br />samples will be collected from each boring at a depth of 5 feet bgs, 10 feet bgs and 15 feet bgs. <br />If the coarse-grained subsurface is too dense to allow advancement of a hydraulic push-drive <br />sampling system, the drilling system will be changed to hollow-stem augers and samples will be <br />collected using a split-spoon drive sampler. The sampler will be fitted with metal liners and <br />driven to the desired sampling interval, whereupon the sampler is removed and the appropriate <br />metal liner is capped and sealed as described above for submittal to the laboratory. <br />Soil borings will be sealed with neat cement or hydrated bentonite chips in accordance with <br />SJCEHD requirements. Drilling residuals (soil cuttings and decontamination rinsate water not <br />used to mix cement) will be placed in sealed containers, pending characterization and <br />coordination for offsite disposal. The containers will be marked and placed in a secure location <br />designated by BNSF. Following acceptance, the drilling residuals will be transported to an <br />appropriately permitted offsite disposal facility. <br />Re-usable sampling equipment will be decontaminated between locations either by <br />steam-cleaning, or washing using non-phosphate soap, a potable water rinse, and a final <br />distilled water rinse. <br />BNSF Mormon Yard - Soil Sampling <br />Site-Specific Health and Safety Plan <br />Mormon Yard, Stockton, California <br />© 2016 Kennedy/Jenks Consultants <br /> Page 8 <br />Ilsfocathprojectslis-proj1201311365020.01_bnsf stockton work planI2016 hrsc work planlappendiceskappendixb_hasp12016.hasp_2015contentinal docx
