INSPECTION DATE_August 19, 1999 INSPECTOR'S INITIALS TAS
1. A site inspection was made of the Road Runners Rest II Pit permitted by Suburban Sand &
Gravel Co. Present during the inspection was Steve O'Brian representing the current operator
(Aggregate, Inc.). The purpose of the site inspection was to continue with measurements
necessary for determination of a current reclamation cost. Pit slope lengths and
measurements were field verified and cross referenced from a map of current disturbances
submitted by the operator on March 31, 1999. The map is based on an aerial photograph of the
pit taken on January 6, 1999. The measurements were part of the Division's on-going
reclamation cost evaluation begun during a previous inspection on February 26, 1999.
2. During an August 30, 1999 site inspection of the adjacent Henderson Industrial Park, the
operator (Jim Felix of Cat Construction, Inc.) noted that overburden and topsoil stockpiled
along the northeast permit boundary of the Road Runners Rest II Pit has "spilled" over the
boundary fence and onto the Henderson Industrial Park permit area. This inspector notes the
volume of material involved is negligible; however, the Division considers this matter to be
a problem and requests that Che operator of the Road Runners Rest II Pit complete the
following corrective measures on or before September 24, 1999 a) "pull" back the stockpiled
material from the permit boundary fence a distance great enough to minimize any further
sloughing of materials offsite, b) establish a setback distance from the boundary fence for
stockpiled materials and commit to maintaining the setback distance throughout the life of
mine, and c) submit photographs verifying completion of the requested corrective measures.
Please see page 5 for details.
3. The Road Runners Rest II Pit is permitted for a total disturbance of 168.41 acres. The
operator has posted a financial warranty of $68,500 in the form of a corporate surety. The
designated post-mining land uses are private recreation and wildlife habitat. The mining
plan has recently been revised to allow for pit dewatering and dry mining methods. The
reclamation plan specifies creation of one large lake approximately 135.66 acres with
perimeter slopes of 3:1 or less from five feet above to ten feet below the water level.
Other shoreline slopes will be regraded to 2:1 or less. Shoreline slopes above the water
line and adjacent areas will be scarified, topsoiled, mulched, and seeded with a rangeland
seed mix. A minimum topsoil cover of 6 inches will be applied. (The Division recommends the
operator reapply 12 to 18 inches of topsoil wherever possible, but will only require a
reclamation bond adequate for replacement of 6 inches of topsoil).
4. A significant portion of the permit area has already been mined. There is an "island"
in the center of the permit area that is currently used as a plant site and storage area for
finished product and topsoil. Surrounding the island is a series of ponds. This island will
eventually be excavated and removed, thereby resulting in one large lake. In order to
evaluate a current reclamation cost based on existing disturbances, this inspector notes the
following reclamation tasks to be completed:
reduce 8,727 linear feet of northeast and northwest pond slopes from 0.75/1 to 3:1 & 2:1;
slopes average 18 feet high
reduce 4,866 linear feet of southwest pond slopes from 1:1 to 3:1 & 2:1; slopes
average 10 feet high
reapply 2,420 cu.yd. topsoil over 3.0 acres of regraded shoreline
scarify (rip) 32 acres of plant site, office, and storage area
