w • Estimates of the undrained shear strength of cohesive soils will be made using a hand-held pocket penetrometer and/or a torvane shear device, as appropriate.The borings will be logged by a field engineer or geologist who will package samples and transport them to the laboratory for further evaluation and testing. • Upon completion of drilling, the excavations will be backfilled with neat cement grout per PG&E practice. Drill cuttings and fluids will be contained in DOT-approved, 55-gallon steel drums and staged onsite. Samples will be obtained for analytical testing, as described below. Task: Drum Testing and Disposal Excess drill cuttings and fluids will be contained in steel drums, and a sample will be obtained for analytical testing.The anticipated analytical testing includes a suite comprised of one of each of the following tests, unless otherwise noted: • pH • TPH Diesel/Motor Oil/Gasoline/BTEX (EPA Method 8015M or equivalent) • CAM 17 metals (EPA Method 6020A, 7471B or equivalent) PG&E will be responsible for providing a secure staging facility for drums. This location must be determined prior to mobilization for the field investigation. If the staging facility is located greater than 30 minutes from the jobsite, additional fees for transport of the drums will apply. The analytical results will be delivered to the PG&E Environmental Field Specialist for determination of hazardous/nonhazardous status. Once confirmed to be non-hazardous, drill cuttings and fluids will be off hauled by our subcontractor. If determined to be Hazardous, PG&E will be responsible for disposing of the spoils. Task: Geotechnical Laboratory Testing Laboratory tests will be performed on selected samples retrieved from the exploratory boring to evaluate the physical and engineering properties of the materials encountered.Tests may include the following: • Grain-size analyses and Hydrometer(ASTM D422)
