(ContiGroup)French <br /> Camp Grain Elevator facility at 9504 South Harlan Road in French Camp (site). The Report <br /> discusses the pilot test that consisted of extracting groundwater from monitoring well MW-3B <br /> and disposing of the groundwater off-site. Although concentrations in the groundwater <br /> decreased, there was a small radius of influence from the pumping. Based on the small radius of <br /> influence and constraints due to the site being active with heavy equipment and hauling trucks, <br /> the Report states groundwater extraction is not a feasible remedial alternative. The Report <br /> proposes two phases of Hydrogen Releasing Compound(HRC) injection. The first phase would <br /> include multiple injections at the downgradient extent of the plume, the progress of which <br /> ContiGroup would monitor for six months and then use the results to design the second phase of <br /> HRC injections. <br /> The Report proposes to submit an application for waste discharge requirements that will include <br /> the proposed injection points. The application needs to include bench-scale study results to <br /> determine appropriate discharge and monitoring requirements. By 10 June 2003,please submit <br /> a work plan to conduct bench-scale testing for the use of HRC.
