I have no access issues with this site. I have blasted in tighter quarters than <br /> 'this. <br /> Thanks, <br /> Tylor McMillan <br /> VVVVTI /VVelenco <br /> Project Manager/ Blaster <br /> (916) 761-5224 <br /> ' On Tuesday, October.15, 2013 11:39 AM, Adrienne Ellsaesser[EH] <AEllsaesser(cDsicehd.com> wrote: <br /> Hi Tylor, - <br /> The proposed destruction method of using explosives beginning at 20' below grade is acceptable. Are you <br /> planning to use a sacrificial PVC trimie tube that will be left and exploded in the well, after the well is filled with <br /> grout? <br /> My concern on this project was why the wells could not be over drilled, as that is what is required. Blasting the <br /> well and leaving the contents in the borehole is only allowed after it is demonstrated to us over drilling the well <br /> is not possible. My staff states they claim the canopy is in the way for a drill rig to gain access to the wells for <br /> the over drill. Do you have any access issues? <br /> Thanks <br /> Adrienne <br /> Adrienne Ellsaesser, REHS <br /> Program Coordinator <br /> San Joaquin County <br /> Environmental Health Department <br /> 1868 East Hazelton Avenue <br /> Stockton , CA 95205 <br /> Ph (209)468-0343 <br /> Fax (209)468-0341 <br /> aellsaesser(o)sjcehd.com <br /> From: tylor mcmillan [mailto:mcmillans521(cr_yahoo.com] <br /> Sent: Tuesday, October 15, 2013 10:33 AM <br /> 1 <br />
