As per your suggestion, I have reviewed the <br />construction of these holes and the geology and believe that only monitoring holes N13, <br />N16P1, N43, and N46 would require plugging by utilizing a "tremie pipe' and positive <br />displacement. <br />D~~ <br />O'Hara <br />GMO:jag <br />Cc: Murari Shrestha <br />Ross Gubka <br />Director of Technical Services <br />PO Box 33424 Denver, CO 802333424 Telephone 303/25~r3070 rax 303/2543079 1100 West 116th Avenue Westminster, CO 80234 <br />
