Long <br />D rvmm~ Director <br />The Colorado Mined Land Reclamation Division proposes to approve <br />your technical revision application to begin auger mining of Auger <br />Mining Area ¢1 as proposed. This approval is with the <br />understanding that Colowyo is committed to marking the location of <br />auger mining on the ground in such a manner that the area augered <br />can be located at time of bond release. <br />In a memo to me dated May 14, 1993, Shawn Smith and Jim Pendleton <br />of the Division requested that monuments be placed over the site to <br />be augered in order to monitor for subsidence. As you pointed out, <br />since the area to be undermined has not yet been backfilled and <br />graded, it would be impossible to separate the effects of fill <br />settlement from the effects of subsidence due to auger mining. <br />After a follow-up consultation with Jim Pendleton, the Division <br />accepts Colowyo's assertion that placing monuments on the site <br />would not provide accurate information in this case and that <br />marking the site will be sufficient for detecting major problems <br />associated with auger mining. <br />As a result of this revision, Colowyo's bond liability will not <br />increase. The Division thanks you for your patience and wishes you <br />success in your efforts to auger mine additional reserves. <br />If you have any questions, please contact me. <br />Sincerely, <br />~~~Z~t.-=-~- <br />(Stephen F.
