Highway 99, Stockton, CA <br /> Dear Mr. Barton: <br /> I am writing to provide the additional information requested in your letter dated October 6, 2003 <br /> regarding the Application/Report of Waste Discharge (ROWD) for Waste Discharge <br /> Requirements (WDRs) for the referenced facility. This submittal was prepared by Ground Zero <br /> Analysis, Inc. (Ground Zero) at the request of Tuleburg Warehouse in order to implement <br /> interim groundwater remediation as required by the San Joaquin County Environmental Health <br /> Department(EHD). <br /> The following additional information is provided: <br /> 1. An estimate of breakthrough time for the Granular Activated Carbon GAC units used for <br /> treatment of upundwater. Ground Zero contacted several contractors regarding breakthrough <br /> estimates. Carbon usage has been estimated at between-37 and 63 pounds per day, depending <br /> upon the type of carbon used. At this rate the primary carbon vessel would initially require <br /> change out every 31-54 days, based upon the most recent analytical results from well MW 1. <br /> Carbon usage estimates are attached. <br /> 2. The com Tete list of re uired laboratory analyses for influent and effluent samples. Treatment <br /> system influent and effluent samples will be collected at the frequency and for the constituents <br /> listed in Attachment A and the Monitoring and Reporting Program for Order No. R5-2003- <br /> 0044, General Order for Land Disposal of Groundwater and Surface Water from Cleanup of <br /> Petroleum Fuel Pollution(Attached).
