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 /> IIf `nested' wells were installed at the site and need to be destroyed by overdrilling, an <br /> auger larger than the original auger must be used and centered on the deepest casing <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 /> • All groundwater displaced to the surface during grout installation shall be pumped out of <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'. uction Permit Application. <br /> Deadline for submittal of the work plan is December 30, 2011. 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 Lori Duncan at (209) 468-0337 or by email at <br /> -:iduncan sicehd.com. <br /> Sincerely, <br /> (9sLt` ��t�wtco� <br /> Lori Duncan, REHS <br /> 'Senior Registered Environmental Health Specialist <br /> c: James Barton., PG,.CVRWQCB, 11020 Sun Center Drive #200, Rancho Cordova, CA 95670 <br /> David Evans, Arcadis 950 Glenn Drive #125, Folsom, CA 95630 <br /> { <br /> 1 <br /> - i <br /> I <br />
