You're contesting 13 wells out of <br /> 89? <br /> 1 can't remember, are you prepared for "a hole, one foot <br /> larger in diameter than the originally drilled hole, shall be <br /> excavated around the outside of the well casing to a depth <br /> of 3-feet below the ground surface, and the well casing <br /> shall then be cut off 6-inches above the bottom of this <br /> excavation and removed"? For an 8-inch borehole, that's <br /> a 20-inch hole and this is the requirement for pressure <br /> grouted wells (wells where the casing, filter pack, <br /> bentonite, and grout seal are left in place). <br /> I can't seem to find the actual work plan for the well <br /> destructions. Have you submitted it to me? IF not, please <br /> do. I'll continue to look for it now that you are working on <br /> this site again. <br /> Mike. <br /> From: Josh Ewert [mailto:ewert@geoconinc.com] <br /> Sent: Friday, November 04, 20114:27 PM <br /> To: Mike Infurna [EH] <br /> Subject: RE: 5400 and 5606 Pacific Avenue, Stockton - Well Destruction <br /> Information <br /> 12/20/2011 <br />
