(AGE). The Report discusses the application of a modified <br /> Fenton reagent (diluted hydrogen peroxide solution with acid) injected into the wells at the site <br /> and how it effectively decreased dissolved hydrocarbon concentrations. In the Report AGE <br /> recommended preparation of a corrective action plan (CAP). The CAP will detail all previous site <br /> investigations performed to date and the results of all pilot remedial studies conducted. AGE <br /> proposes to submit a final remedial action plan (FRP) within the CAP, proposing ISCO as the <br /> best available technology for the remediation of the hydrocarbon impacted soil and groundwater <br /> at the site. In addition, the FRP will propose all ISCO injection well locations, well construction <br /> and detailed procedures for full scale implementation. Proceed with the CAP and submittal to <br /> the EHD. <br /> If you have any questions please contact Lisa Medina at (209) 468-3455 or by email <br /> Imedina@sjcehd.com. <br /> Lisa edina, REH Nuel C.
