Groundwater Well Installation Work Plan Sharpe Army Depot <br /> Lathrop, California <br /> Initial phase inspections are conducted after activities begin to check and document that work is being <br /> performed, as discussed during the preparatory phase inspection. A QC staff member is responsible for <br /> monitoring the quality of the construction work performed. During the initial phase inspection, a <br /> representative sample of work is observed to document that the work complies with the specified <br /> requirements. <br /> Follow-up phase inspections are performed daily after the initial phase until the completion of the work <br /> to check and document that work is being performed according to plan. <br /> Quality Assurance includes the planned and systematic actions necessary to provide a sufficient <br /> confidence level that the structure, system, or component will perform satisfactorily in service. Quality <br /> assurance consists of a multi-disciplinary system of management controls backed by quality verification <br /> and overview activities that demonstrate completeness and appropriateness of achieved quality. Quality <br /> assurance inspections are performed during well drilling by USACE personnel to ensure the work is <br /> completed as planned. The activities described in the Work Plan will be conducted by the QAPP (Ahtna, <br /> 2022b). <br /> 5.0 Site Safety and Health <br /> Project activities will be conducted following the QAPP(Ahtna,2022b),APP(Ahtna,2022c),SWMP(Ahtna, <br /> 2022d), and applicable SOPS (Appendix C). As part of the plan, Ahtna has prepared supplemental <br /> documentation, including activity hazard analyses pertaining to well-installation activities. Tasks will be <br /> conducted to protect the safety and health of employees and members of the public and comply with the <br /> Occupational Health and Safety Administration and USACE Health and Safety Requirements, according to <br /> the 2014 EM 385-1-1 (USACE, 2014).A separate investigation is currently underway at Sharpe to evaluate <br /> Per-and Polyfluoroalkyl Substances in groundwater. Precautions for worker protection related to Per-and <br /> Polyfluoroalkyl Substances are the same as for VOCs. <br /> Ahtna Environmental,Inc. 19 <br />
