Lochhead <br />Eaecuhve Director <br />M¢hael B. Long <br />Division Direcioi <br />Pursuant to Rule 1.4.5(6), on August 4, 1995 the Division of <br />Minerals and Geology decided to recommend that the Colorado Mined <br />Land Reclamation Hoard approve with conditions your 112 Amendment <br />Application to the Sandy Acres Pit Permit. The conditions, <br />outlined below, are necessary in light of the currently approved <br />mining plan which allows mining within 10' of property lines. <br />STIPULATION NO. 1 <br />The operator will maintain all above and below water slopes during <br />mining at a 3:1 grade. The northern and eastern slopes which have <br />previously been mined to less than 150' of the fence will be <br />backfilled with overburden and wash fines to achieve 3:1 slopes to <br />10'below the water level and 2:1 slopes to the pit bottom. <br />Alternatively, operator may submit the additional bond required to <br />import sufficient pit-run material to achieve the above and below <br />water grades of 3:1 and 2:1 outlined in the reclamation plan. The <br />volume of pit-run required to augment on-site stockpiled material <br />is estimated by the Division at 508,000 yds. The cost per yard is <br />estimated at $8.00/yd. for a total additional cost of <br />$4,064,000.00. <br />The Division has reviewed the estimate of reclamation costs <br />supplied by the operator. If the operator agrees to maintain 3:1 <br />slopes during mining, the required reclamation bond has been <br />calculated at $133,000.00. The bond is currently set at <br />$92,37~The operator must submit a rider to the current bond <br />
