' plan, site safety procedures for specific site operations, (e g , drilling, etc ), a decontamination plan, and <br /> an emergency response/contingency plan The CHASP will specify levels of protection for site personnel <br />' on a task-specific basis As with any project of this magnitude, there are inevitable encounters with a <br /> variety of physical hazards ranging from simple housekeeping to temperature extremes ATC will provide <br /> continual evaluation of all potentially hazardous conditions, as the project is undertaken and prescribe <br />' additional safety protocols to protect site personnel as needed <br />' 5.2 Permitting <br /> ATC will complete well permit applications to drill and install the groundwater monitor and remediation <br /> wells (MW-13 through MW-17, EX-1 and VEAS-1 through VEAS-3) and submit them to the SJC prior to <br />' initiation of fieldwork <br /> 5 3 Drilling and Soil Sampling <br /> Prior to drilling the soil borings, ATC will contact Underground Service Alert (USA) and a private utility <br />' locator service to locate possible subsurface utilities in the vicinity of the proposed boring locations <br /> Following utility clearance, drilling will be scheduled ATC proposes to utilize a hollow-stem-drilling rig <br /> equipped with 10-inch diameter augers Additional details are provided below <br /> tATC proposes to install five groundwater monitor wells The proposed location of each remediation well <br /> is illustrated on Figure 4, Proposed Well (MW-13 through MW-17, EX-1 and VEAS-1 through VEAS-3) <br /> lieLocation Map ATC proposes to drill each groundwater monitor well to approximately 65 feet bgs <br /> Proposed groundwater monitor well construction details are illustrated on Figure 5, Proposed <br />' Groundwater Monitor Well (MW-13 through MW-17) Construction Detail <br /> ATC proposes to install three vapor extraction/air sparge remediation wells The proposed location of <br /> each remediation well is illustrated on Figure 4 ATC proposes to drill each dual completion vapor <br /> extraction/air sparge well to approximately 65 feet bgs Proposed remediation well construction details <br /> are illustrated on Figure 6, Proposed Remediation Well (VERS-1 through VEAS-3) Construction Detail <br /> ATC also proposes to drill and install one six-inch diameter groundwater extraction well on-site (EX-1) <br /> The proposed location of EX-1 is illustrated on Figure 4 ATC proposes to drill EX-1 to approximately <br /> 70 feet Proposed remediation well construction details are illustrated on Figure 7, Proposed Groundwater <br /> Extraction Well (EX-1) Construction Detail <br />' The well borings will be drilled and sampled in general accordance with ATC's Standard Operating <br /> Procedure — Soil Borehole Drilling, Monitor Well Installation and Development, and Soil Sampling, which <br /> is included in Appendix A Undisturbed soil samples will be collected at 5 to 10 feet intervals from the <br /> borings These samples will be utilized for analytical testing, lithologic logging and waste <br /> characterization purposes <br /> EZ 100966SAFSWP ATC Associates Inc <br /> S IEZ Serve1EZ 100966U2eports1100966SAFSWP ATC Project No 43 25827 0026 <br /> 7 <br />
