plan; site safety procedures for specific site operations, (e.g., drilling, sampling, etc.); a decontamination <br /> plan; and an emergency response/contingency plan. The HASP specified levels of protection for site <br /> personnel on a task-specific basis. As with any project of this magnitude, there are inevitable encounters <br /> with a variety of physical hazards ranging from simple housekeeping to temperature extremes. IES will <br /> provide continual evaluation of all potentially hazardous conditions and prescribed additional safety <br /> protocols to protect site personnel as needed. <br /> Permitting <br /> IES will secure encroachment permits from the City of Stockton for the thirteen (13) groundwater wells <br /> located in the City Right of Way (ROW) (MW-4, MW-6, MW-7, MW-8, MW-12, MW-13A, MW-14B, <br /> MW-1513, MW-16C, MW-17B, MW-18C, MW-19B and MW-20C). After securing the encroachment <br /> permit, IES will complete the well drilling permit application to destroy twenty-one (21) groundwater <br /> monitoring wells (MW-1 through MW-9,MW-10A, MW-11B, MW-12B, MW-13A, MW-14B,MW-15B, <br /> MW-16C, MW-17B, MW-18C, MW-19B, MW-20C and EX-1) and submit the application to DEH for <br /> approval prior to initiation of field work. Locations are shown on Figure 1. <br /> Utility Clearance <br /> Prior to well destruction activities IES will mark-out the drilling locations with white paint, white stakes <br /> and/or white flags and contact USA to identify utilities in the vicinity of each drilling location as required <br /> by law. <br /> Well Destructions <br /> IES will contract with Baja Exploration Inc., a C-57 licensed driller(License#804318)to conduct the well <br /> destructions. Preceding backfilling and over-drilling activities, well casing and borehole measurements <br /> from each location will be confirmed. Well casings will be extracted prior to over-drilling each well to <br /> approximately 1-foot below the total measured depth. Over-drilling beyond the total explored borehole <br /> depth will remove the remaining well construction materials, including the sand filter packs and annular <br /> seals. The destroyed well boreholes will be backfilled with a Portland cement and bentonite grout mixture <br /> with 5% (or less) bentonite content by volume via tremie pipe from the bottom up. Following grouting, <br /> well vaults will be destroyed to remove all well construction materials from the upper 3 feet of the <br /> borehole, including the concrete perimeter seal. The borehole will then be capped with approximately 3- <br /> feet of 3,000 psi traffic-rated concrete. Each destroyed well will be finished at the surface to match <br /> existing grade. <br /> Waste Management <br /> All investigation derived waste(IDW)will be managed in accordance with all state and local regulations. <br /> Well materials from the upper five feet of each well(excluding concrete and PVC), and any <br /> decontamination rinseate,will be placed in 55-gallon,California Department of Transportation rated <br /> drums which will be labelled with non-hazardous waste labels and temporarily stored on-Site pending <br /> waste characterization and eventual transport under manifest to an appropriate receiving facility for <br /> disposal. Concrete,PVC and other construction materials will be transported to an appropriate landfill for <br /> disposal.Any recyclable metals will be transported to a facility for recycling. <br /> Following completion of the activities proposed above, IES will submit a Well Destruction Report to the <br /> CVRWQCB and DEH detailing the activities associated with well destruction activities. <br />
