%moo, NOOO <br /> Mr. Harlin Knoll <br /> July 6, 1999 <br /> Page 2 <br /> V&W will abandon the three wells using the pressure grout method. V&W will mix a <br /> 20:1 cement:bentonite grout in a trailer-mounted cement mixer, equipped with a grout <br /> pump and tremie pipe system. The grout will be pumped to the bottom of the wells using <br /> a one-inch diameter PVC tremie pipe. Pressure will be applied during pumping using a <br /> wellhead regulator cap outfitted with a water release hose. Any groundwater displaced <br /> by the grout out the top of the well will be contained in five-gallon buckets and screened <br /> olfactorily for petroleum odor. If free of petroleum odor,the displaced groundwater will <br /> be discharged on-site to the land surface away from any storm drains or property lines. <br /> Each of the wellhead street boxes will be removed and any exposed well casing will be <br /> cut off. Solid waste will be disposed off-site as construction debris. Once the street <br /> boxes have been removed, the remaining hole will be filled with ready-mix concrete. <br /> The concrete surface will be finished smooth to grade. <br /> Upon completion of the well abandonment, Ramage Environmental will prepare and <br /> distribute a letter report documenting the operations. The report will be prepared and <br /> stamped by a California Registered Geologist. The report will include copies of the <br /> Department of Water Resources(DWR) well completion reports for the abandoned wells. <br /> The well abandonment work is scheduled for Thursday duly 22, 1999,beginning at <br /> 8:30 am. At least two working days prior to field activities, PHS/EHD will be notified so <br /> that field inspection schedules can be confirmed. The field activities should be <br /> completed in one, half-day. <br /> Thank you for your assistance on this project. If you have questions or need any <br /> additional information,please call me at (916) 354-3250. <br /> Sincerely, ���► <br /> RAMAGE ENVIRONMENTAL ''' <br /> Joseph Ramage, R.G. �. <br /> Project Geologist �'�l��F <br /> CAI. <br /> Attachments: Permit Application, Declaration and Check for Permit Fee ` <br /> Figure 1 (Site Location Map) and Figure 2 (Site Plan) <br /> Table, Monitoring Well Construction <br /> CC: Mr. Anthony Varni, Esq. - Varni, Fraser, Hartwell & Rodgers <br /> Mr. Mark List--Central Valley Regional Water Quality Control Board <br />
