-Title- «FirstName» «La stName>> Page 2 of 3 groundwater extraction, treatment, and discharge to the ground surface. The system will consist of four major components: 1) extraction well, 2) a treatment system, 3) a conveyance system to the treatment system, and 4) a discharge area. An existing 4-inch diameter well (MW1) will be.utilized as the groundwater extraction well. Contaminated groundwater will be pumped from well MWl through subgrade piping to the.treatment system. Extracted groundwater will be processed through two 2,000-pound granular activated carbon (GAC) units, which will be configured in series. Sample ports will be located between all vessels to allow detection of potential contaminant break through and to obtain samples immediately prior to discharge. Treated effluent will be discharged to the ground surface via surface sprinkler(s) after the effluent has been verified non-detect by laboratory analyses. The primary chemicals of concern include the gasoline constituents MTBE, benzene, toluene, xylenes, and ethylbenzene. LOCATION OF TREATMENT SYSTEM AND DISCHARGE The treatment system will be located near the northeast cornier of the intersection of Foppiano and N. Highway 99 East Frontage Road, approximately 30 feet southeast of the Speedy Foods Store building. The discharge area will be an area approximately 40 x 100 feet, with the long axis running parallel to Foppiano, beginning approximately 170 feet east of the Frontage Road. A site plan showing the location of the extraction well, treatment system and area of discharge is presented on Figure 2. PERMIT APPLICATION AND PROJECT IMPLEMENTATION TIME SCHEDULE Ground Zero, on behalf of Tuleburg Warehouse, has submitted an Application/Report of Waste Discharge to the RWQCB in order to obtain a Waste Discharge Permit pursuant to RWQCB Order No. R5-2003-0044, General Order for Land Disposal of Groundwater or Surface Water from Cleanup of Petroleum Fuel Pollution. Ground Zero is currently working with contractors to install the necessary components of the interim groundwater remediation system. System components should be in place by October 15, 2003. The interim system is expected to be put into operation by October 31, 2003, pending approval of Waste Discharge Permit. We anticipate that the interim treatment system will be in operation at least 6-12 months to evaluate the effectiveness of interim remediation activities. Additional remediation activities may be necessary. PERMIT DISCHARGE LIMITS AND MONITORING PROGRAM The Monitoring and Reporting Program for Order No. R5-2003-0044, General Order for Land Disposal of Groundwater or Surface Water from Cleanup of Petroleum Fuel Pollution, requires that influent and effluent samples be collected from the treatment system on a weekly basis for four consecutive weeks following initial discharge from the treatment system and monthly, thereafter. The samples will be analyzed by a State-certified laboratory for gasoline constituents, including but not limited to MTBE, benzene, toluene, ethylbenzene, xylenes, and other common gasoline constituents. Daily maximum effluent limitations have been established by the State to ensure that water quality objectives are met prior to discharge. G:IGROUNDZEITULEBURGInotification.doc
