We have scheduled the abandoning of the borings from December 19th to <br />December 23rd . <br />Our intent is to ream the borings again and then pour cement grout in the borings if drill rig is <br />able to drive to the well boring locations. This method is weather dependent. If the drill is not <br />able to access the well boring locations, then we would abandoned the wells in accordance <br />with the approval received from Robert McClellon. The alternate abandoning process <br />approved by Robert involves pulling the temporary 1 -inch casing from the boring and leaving <br />the sand pack inside. A diluted neat cement will be first pumped in the boring to percolate in <br />the sand pack. Regular mix of neat cement will then pumped afterwards. <br />The driller has been notified about EHD's inspection time from 9:00am to 3:30 pm. We <br />anticipate the driller will be ready for inspection at 10.00am on the first day. We will notify you <br />about the other consecutive inspections in the field after the first inspection. If there are any <br />other changes, I will notify you as soon as possible. <br />Please let me know if you need any additional information. <br />Thanks <br />JOYESH CHANDRA <br />SAN JOAQUIN COUNTY <br />PUBLIC WORKS DEPARTMENT <br />SOLID WASTE DIVISION <br />PH: (209) 468-3066 <br />Fax: (209) 468-3078 <br />From: Michael Carroll <br />Sent: Monday, November 14, 20114:18 PM <br />To: Natalia Subbotnikova [EH] <br />Cc: 'John Hower'; 'Robert McClellon [EH]' <br />Subject: Abandoning the temporary Corral Hollow Wells <br />Hello Natalia, <br />We found low levels of two VOCs in the temporary wells at Corral Hollow, and can't tell where edge of the <br />12/8/2011 <br />
