Page 4 of 5 <br /> One-inch and 3/4 inch wells to be drilled out must have the process <br /> approved ahead of time. Drilling out a small diameter well is problematic <br /> since `centering' on the casing is very difficult. Provide a method to do this. <br /> recommend a Plan B for this procedure since so many Plan A's typically <br /> fail to stay on the well to TD. Failed attempts will not be allowed to use on <br /> subsequent well destructions unless adequate methods are employed. — <br /> Understood, plan A is a 8-inch diameter auger will be used to remove the <br /> well the entire depth of the well casing. Plan B is a 12-inch diameter auger <br /> will be used to remove the well the entire depth of the well casing. Plan B <br /> will only be used if Plan A is not successful. <br /> Your plan/modifications must be approved by noon, Wed Nov 9 in order for <br /> you to drill Monday Nov 14. <br /> Friday, Nov 11 is a County holiday and the office is closed. I am out of the <br /> office Thurs, Nov 10th. Your submittals must be here and complete by <br /> NOON, Wednesday, Nov 9 so I can review them some time during the <br /> afternoon Wed, Nov 9 or I will not have time to process and issue the <br /> permit so you can drill Monday, Nov 14. I have to also set up coverage for <br /> this work with other inspectors so I need as much time as you can provide. <br /> Submittals from you today could go a long way in securing a Monday start <br /> for you. <br /> Mike. <br /> From: Eisert, James [mailto:James.Eisert@arcadis-us.com] <br /> Sent: Friday, November 04, 20114:43 PM <br /> To: Mike Infurna [EH] <br /> Cc: Hackman, Scott <br /> Subject: Tracy, CA - Maintenance Facility - Well Destructions <br /> Hi, Mike <br /> In response to your information request during your call with Scott Hackman today, please see <br /> attached revised permit application (including a scanned copy of the permit fee payment check) <br /> and work plan for well destruction which was submitted to the RWQCB. <br /> In addition, answers to your specific questions are below. <br /> VMP-1 through VMP-5 are vapor monitoring points consisting of a flush mount, 8-inch diameter <br /> well box over buried %-inch diameter Teflon tubing extending through a hydrated bentonite <br /> surface seal.The actual depth of the borehole associated with the VMPs is unknown due to the <br /> surface seal.To destroy the VMPs the well box and tubing will be removed and the borehole will <br /> be grouted to the surface. <br /> Contrary to the attached work plan, all proposed wells except MW-213, -313, -3C, -166, -1713, - <br /> 11/8/2011 <br />
