Geological re"cs/Kc. <br /> Valentine Property <br /> Project No.:723.2 n <br /> Well Destruction Work Plan - - <br /> t <br /> December 10;2012 <br /> A neat cement grout(containing less'than o bentonite)will be pumped under pressure <br /> through a tremie pipe.to the bottori of th well. .In,this manner, the grout will displace . . <br /> the water in the well ensuring that it is 'o pletely filled with grout. <br /> • After the grout has been filled to Neto of the well, a pessure cap will be fitted to the <br /> casing and the well pre§surized.to,�25 si. If the grout settles, additional grout will.be <br /> pumped into the-well casing. This will.force the cement into the filter pack. <br /> • .The amount of eeinent grout.volume needed.td,fill the well and the horizontal piping has <br /> been calculated (attached'tables) and the amount 'utilized will "be tracked to judge the ; <br /> effectiveness of-the process. ' <br /> • After the grout has been installed,' the top of casing of the three monitoring wells will be <br /> drilled out to a depth of 5 ft below grade and the holes will be filled.with clean dirt and <br /> capped with asphalt or concrete in.the upper 8 inches below grade for wells in asphalted <br /> or concrete areas(respectively): The other,.12 various wells will be drilled out. � � 1 <br /> Remedial Equipment Removal. i <br /> Prior to well destruction,Geological"Technics Inc. will remove of all remediation equipment Sci <br /> and security fencing. a <br /> Schedule,&Reporting ' <br /> Our goal is to complete the well abandonment work.by mid February 2013, contingent upon <br /> Work Plan approval. <br /> The information gathered during this phase of work will be presented.in a report, which will <br /> include a discussion of well destruction efficiency(grout volume utilized versus.calculated i <br /> expectations). <br /> The project will be supervised by:Pn.•Ray Kablanow; the registered professional geologist ; <br /> responsible for the work. Copies of the reports will be forwarded'to 'both the appropriate <br /> .County and State regulatory.'agencies. <br /> If you should have any questionsplease do riot hesitate to call. <br /> Respectfully Submitted, ' <br /> itali signed Ra noldKablanow ��NAL G <br /> 9 Y y Y Y . � FQ`Q <br /> Ra N:cn=Raynold Kahlanow,o, <br /> i=Genf 'cal Tech <br /> `•,. <br /> e -ail-gti@gti v.c a" IiAYNOLD <br /> KaTb -4 �o a KAB�allow �+ <br /> G <br /> Raynold t Kablanow ll,Th.D.
