• �"` PRIVILE�:6 & CONFIDENTIAL Y' A tailgate safety meeting will be conducted by the Project Manager to discuss the anticipated risks,potential health hazards, and the precautionary measures to be observed to prevent accidents. The meeting will be conducted to ensure that all field personnel read and •– understand the H&S Plan. As part of the health and safety measures, air monitoring will be performed during the process of augering and sampling, using vapor detection equipment such as the photoionization detector(PID). Prior to the start of the drilling, ambient air measurements will be taken and recorded. At regular intervals, air measurement will also be performed within the breathing zone of the drilling operator and at the boreholes. Permitting and Communication with the Agency ti Building Analytics has completed SJCEHD monitoring well permits for the additional soil boring, and for the conversion of this boring into a permanent monitoring well. The well permit is enclosed. Building Analytics shall notify the SJCEHD of the proposed date of the field activities. Utility Clearance Building Analytics shall retain the services of Underground Services Alert (USA) and a private underground utility locator to mark the approximate locations of subsurface objects such as electrical conduits, and sewer and water pipes. Soil Boring and Sampling One borehole will be drilled using a drill-rig equipped with eight-inch augers to depths extending ten feet into the aquifer, 70 feet bgs or auger refusal, whichever occurs first. The proposed boring location is: • Boring B-4 (MW-4) shall be south of the bank building between previous Borings P-1 and P-2 (Figure 1). The boring location shall be on land owned by Wells Fargo Bank. The boring location is illustrated in Figure 1. Should space restrictions cause the moving of the boring location — onto the sidewalk or street, an additional permit will be required. Soil samples will be collected from each borehole at 1.5 feet bgs,and thereafter at five-foot intervals starting at a depth of five feet bgs. Approximately 15 soil samples will be collected for this project. The soil samples will be collected in brass tubes, sealed with Teflon tape, labeled and recorded, and placed on ice for shipment to a state-approved laboratory. For the purpose of this proposal, Building Analytics has included the analysis of five soil samples. If soil contamination is indicated by the analytical results, further analyses of additional soil samples could be required. All soil samples will be screened in the field for volatile organic compounds (VOCs) using portable vapor detection equipment such as a PID. The PID readings will be recorded on the boring log by the on-site geologist. Based on the PID readings and field observations, r the geologist will select soil samples for the laboratory analysis. 3 197501-WFB.Stockton Workplan
