The grout seal of I13-12 is within two inches of an old vapor recovery line,about three feet below grade. The line is an 8" <br /> or 10" fiberglass pipe which, if straight, is also too close to the other three wells along the fence. <br /> Tracing the vapor recovery line past MW-14 on the surface suggests that it will be much too close to the required <br /> fifteen-inch auger overdrill required for that well. The same line may also be too close to P-5 and P-6. <br /> We employed Cruz Brothers Locators to attempt to trace the line, but had little luck due to it being fiberglass and not <br /> metal. We re-exposed the pipe at IP-12 to confirm its orientation, but cannot trace it without breaking it. Fiberglass <br /> lines are usually for petroleum product, and though this one is"abandoned",that term does not have the same meaning <br /> for pipes that it does for wells. <br /> Cardno ATC is requesting that we be allowed to pressure grout these five wells. I13-12, P-5, and P-6 have been opened up <br /> by vacc truck ("air knife") and can be mushroom capped without using a drill rig. MW-14 is in a 12" by 24" shallow vault <br /> style well box,which can be filled to function as a mushroom cap. MW-4 is too close to the propane pipe for demo <br /> work, but the well box can be filled to grade. <br /> Jim Kundert <br /> STAFF GEOLOGIST <br /> CARDNO ATC <br /> Cardho <br /> ATC <br /> Phone(+1)209.579.2221 Fax(+1)209.579.2225 Mobile(+1)209.996.2767 <br /> Address 1117 Lone Palm Avenue,Suite 201,Modesto,CA 95350 <br /> Email iimAundertacardno.com Web www.cardnoatc.com"www.cardno.com <br /> This email and its attachments may contain confidential and/or privileged information for the sole use of the intended recipient(s).All electronically supplied data <br /> must be checked against an applicable hardcopy version which shall be the only document which Cardno warrants accuracy.If you are not the intended recipient, <br /> any use,distribution or copying of the information contained in this email and its attachments is strictly prohibited.If you have received this email in error,please <br /> email the sender by replying to this message and immediately delete and destroy any copies of this email and any attachments.The views or opinions expressed <br /> are the author's own and may not reflect the views or opinions of Cardno. <br /> 2 <br />
