RE: Sandy Acres Pit, File No. M-80-110
112 Amendment Application Decision
Dear Mr. Siegrist:
Pursuant to Rule 1.4.5(6), on August 4, 1995 the Division of
Minerals and Geology decided to recommend that the Colorado Mined
Land Reclamation Board approve with conditions your 112 Amendment
Application to the Sandy Acres Pit Permit. The conditions,
outlined below, are necessary in light of the currently approved
mining plan which allows mining within 10' of property lines.
STIPULATION NO. 1
The operator will maintain all above and below water slopes during
mining at a 3:1 grade. The northern and eastern slopes which have
previously been mined to less than 150' of the fence will be
backfilled with overburden and wash fines to achieve 3:1 slopes to
10'below the water level and 2:1 slopes to the pit bottom.
Alternatively, operator may submit the additional bond required to
import sufficient pit-run material to achieve the above and below
water grades of 3:1 and 2:1 outlined in the reclamation plan. The
volume of pit-run required to augment on-site stockpiled material
is estimated by the Division at 508,000 yds. The cost per yard is
estimated at $8.00/yd. for a total additional cost of
$4,064,000.00.
The Division has reviewed the estimate of reclamation costs
supplied by the operator. If the operator agrees to maintain 3:1
slopes during mining, the required reclamation bond has been
calculated at $133,000.00. The bond is currently set at
$92,370.00. The operator must submit a rider to the current bond
