Following that, a hole at least one foot larger in <br /> diameter than the originally drilled borehole shall be excavated around the outside of the <br /> well casing to a depth of 3 feet below the ground surface, and the well casing shall then <br /> be cut off 6 inches above the bottom of this excavation, and removed. The grout used to <br /> seal the well shall then be topped off and allowed to spill over into the excavation and fill <br /> it for a thickness of one foot to form a `mushroom cap' over the top of the cut casing. <br /> If `nested' wells were installed at the site and need to be destroyed by overdrilling, an <br /> n the deepest casing <br /> centered o g <br /> auger larger than the original auger must be used and p <br /> (which is off-center in the original borehole). The auger needs to be sized sufficiently to <br /> reach out and remove all well casings, screens, filter packs, and grout sealant installed <br /> during construction. <br /> installation shall be pumped out of <br /> ed to the surface Burin grout p p <br /> • All groundwater displaced g <br /> the excavation and containerized for proper disposal. <br /> • Any wells located offsite require updated access agreements and/or encroachment <br /> permits to be submitted with the EHD Well Destruction Permit Application. <br /> Deadline for submittal of the work plan is November 30, 2012. After the EHD has approved the <br /> work plan you may submit an EHD Well Destruction Permit Application along with the <br /> appropriate fees. Current fees are: $375.00 per permit, (one permit per parcel) plus $125.00 <br /> per each well on the parcel that is to be destroyed. A nested well is considered to be one well. <br /> If you have any questions please contact Lisa Medina at (209) 468-3455 or by email at <br /> ImedinaCaDsjcehd.com. <br /> Sincerely, <br /> Lisa Medina, RE HS <br /> Senior Registered Environmental Health Specialist <br /> c: James Barton, PG, CVRWQCB, 11020 Sun Center Drive #200, Rancho Cordova, CA 95670 <br /> i <br /> i <br /> i <br />
