It is my understanding that these activities will not require any additional permitting (well installation or <br /> destruction)through the San Joaquin County Environmental Health Department. Adam Brown will contact you <br /> first thin tomorrow morning.9 g Adam is available at(530) 906-4545. A description of the proposed well destruction <br /> and installation activities is provided below: <br /> RSI Drilling will abandon by"overdriIling"the 2" monitoring well 1 foot past the depth of the original <br /> borehole. 8.25" outside diameter hollow stem augers will be used to drill out the well. Upon removal of the <br /> original well materials RSI will tremie grout the borehole to ensure a proper seal. A new borehole will be <br /> drilled approximately 5'from the original borehole for the installation of a replacement 2" monitoring well <br /> with a total depth of 60'. The replacement well be constructed with specifications to match the original <br /> well.All well materials will be placed via tremie pipe to ensure proper construction of the replacement <br /> well. <br /> Please call me with any questions or if you require a modification to the above scope of work. <br /> Greg <br /> Greg McIver <br /> w <br /> Senior Project Scientist <br /> The Source Group,Inc. <br /> Environmental Engineering, Hydrogeologic & Management Services <br /> 960 McCourtney Road, Suite F <br /> Grass Valley, California 95949 <br /> 530.272.4200 office <br /> 530.592.7755 mobile <br /> www.thesour-cegroup.net <br /> The materials transmitted by this electronic mail are confidential, are only for the use of the intended <br /> recipient, and may also be subject to applicable privileges.
