(Condor) requests your written <br /> concurrence that monitor well MW-7 is not needed to monitor groundwater quality under Waste <br /> Discharge Requirements Order No. 99-123. Triple E received a letter from Antonia Vorster, Groundwater <br /> Cleanup Manager dated 25 March 2005, which provides that if Triple E Produce and the Non-Chapter 15 <br /> Section of the Regional Board determine that MW-7 is not needed, Triple E may proceed with permitted <br /> destruction of the well in accordance with San Joaquin County procedures. <br /> Well MW-7 was part of a groundwater remediation monitoring network regulated under Order No. R5- <br /> 2003-0806. The Regional Board previously directed other wells in the aquifer remediation project to be <br /> destroyed, but MW-7 remained for a limited period of monitoring to assure adequate remediation had <br /> been achieved. The well is located approximately 2,000 feet downgradient from well MW-1, contained in <br /> Order No. 99-123, which regulates the discharge of Triple E's process wastewater. The attached map <br /> shows the relationship between these wells and the predominant flow direction collected over ten years of <br /> groundwater monitoring under previous Order No. 96-118. Well MW-7 was placed to monitor the extent <br /> of a remediated plume and is of no practical use in monitoring current discharges upgradient of MW-1. <br /> Please provide written confirmation that MW-7 is not needed for monitoring discharges under Order No. <br /> 99-123. Upon receipt of this confirmation, Triple E intends to proceed with permitted destruction of the <br /> well through San Joaquin County. Thank you for your attention to this request. <br /> Sincerely, <br /> CONDOR EARTH TECHNOLOGIES, INC. <br /> John H.
