FLUOR DANIEL GTI <br /> September 29, 1998 <br /> Mr. Robert Reeves <br /> California Regional Water Quality Control Board <br /> Central Valley Region <br /> 3443 Routier Road, Suite A <br /> Sacramento, CA 95827 <br /> Subject: Former Nestle USA- Beverage Division Facility, Ripon, California <br /> Work Plan for Evaluation of Additional Remedial Actions <br /> Potassium Permanganate (KMnO4) rib t Sts:Ay <br /> Dear Mr. Reeves: <br /> On behalf of Nestle USA, Fluor Daniel GTI, Inc. is pleased to submit the subject work plan for your review. <br /> As we have discussed via telephone, recent experience with KMnO4 has shown that oxidation of <br /> chlorinated compounds can be achieved in an in situ application for groundwater remedial actions. <br /> Chemical oxidation was evaluated in the Feasibility Study as a potentially feasible remedial technology. <br /> The application of in situ oxidation at the Nestle site, if successful, could result in significant improvement <br /> in both the timeframe and economics of the remedial action program. <br /> A schedule for implementation of the pilot study is included in the work plan. In addition, at your request, <br /> we are currently preparing a revised overall project schedule that incorporates the pilot study. This <br /> schedule should be available within 2 weeks following review by Nestle. Based on your feedback on the <br /> project schedule submitted previously, we are evaluating how to shorten the CAO-mandated durations of <br /> design-related tasks following submittal of the Remedial Action Plan (RAP). The RAP will be prepared <br /> upon completion of the pilot study evaluation, allowing incorporation of in situ oxidation, if warranted, <br /> based on the findings of the study. <br /> In the interest of expediting the overall schedule, please note that we plan to begin initial site <br /> characterization and bench scale test activities, concurrent with your review of the work plan. <br /> Please call either Mr. Binayak Acharya of Nestle at(818) 549-5948, or me at(925) 370-3990, if you have <br /> any questions or comments. <br /> Sincerely, <br /> FIuQr Danie GTI, c. <br /> �J►�►li C� Gt CIA�� <br /> Richard M.
