1 l <br /> San Joaquin County since the flows and effluent concentrations would then be comparable to <br /> other systems the County typically regulates. In phone conversations between our engineer, <br /> Robert Beggs of Brown and Caldwell, and Tim O'Brien, Mr. O'Brien mentioned that this <br /> proposal would probably be worthy of consideration by the Regional Water Board. He <br /> requested that I send you this letter with our request. <br /> We propose to perform the following: <br /> • Install a biofilter system to reliably reduce monthly average effluent BOD <br /> concentration below 154 mg/L. <br /> • Sample and verify the performance of the system for 6-12 months after installation. <br /> • Provide whatever documentation would be necessary to enable the Regional Water <br /> Board to return the upgraded system to San Joaquin County jurisdiction. <br /> • Obtain a letter from the San Joaquin County EHD that specifies their willingness to <br /> resume oversight of our waste water disposal system. <br /> We also believe that reducing the BOD will enable compliance with our TDS limit. <br /> Please let me know if this approach seems reasonable to you and if you would generally be <br />` supportive of allowing us to return to County jurisdiction if our results prove the <br /> effectiveness of our wastewater treatment system upgrade. <br /> i cerely <br /> E c enone, Jr. <br /> P sident <br /> cc: Steve Rosenbaum CRWQCB <br /> G_ Tim O'Brien CRWQCB <br /> Robert Beggs Brown and Caldwell <br /> Donna Heran San Joaquin County EHD <br />
