OBSERVATIONS
The inspection report filed after the 7/31/95 inspection of this site included a requirement
to poet an entrance sign in accordance with Rule 3.1.12. The required entrance sign had been
posted at the time of this inspection.
Since the time of the 7J31J95 inspection, the operator had graded and levelled a number of
areas on the floor of the larger pit east of the WYCO Pipeline. Some grading work had also
been completed along both the north and south pit perimeters.
A short section of over-steepened elope was inspected at the south pit perimeter near the
east end of the pit. Because a fairly dense stand of shrubs and small trees had developed
on this elope, the operator wanted to know if it could be left ae it ie for reclamation. The
Divie ion's determination ie that this elope will have to be graded to a maximum elope of 3:1
in accordance with the approved reclamation plan.
The operator had surveyed and staked the elevations of the anticipated water Level once the
pit is allowed to flood. It appears that an extensive shallows, approximately 30 feet in
width, will develop along the eastern end of the north pit perimeter. This shallow area
should promote the development of emergent wetlands vegetation. At the break in slope along
the north pit perimeter, the pit elopes steeply down to a de-watering trench. Given the
extensive ehallowe that will develop at this part of the pit, the Division will relax the 3:1
grading requirement for this elope. The drop-off from the ehallowe along the north pit
perimeter must be graded to be no steeper than 2:1.
The operator wanted to know if trees that are currently below the elevation of the
anticipated water level would have to be removed prior to flooding the pit. Since the number
of trees affected ie small, and because the partially submerged trees may provide wildlife
habitat, the operator would not be required to remove the trees.
Based on observations made during this inspection, and on information provided in a letter
from Siegriat Construction Co. dated 11/6/95, the following reductions can be made in the
Division's previous reclamation cost estimate:
The coat for final grading and establishment of 3:1 slopes can be reduced to $11,572.00.
The coat for ripping compacted areas can be reduced to $1,643.00.
The coat to replace topsoil can be reduced to 60,000.00.
The coat for dewatering can be reduced to $5000.00 (this reduction ie justified because
most of the grading needed below the projected waterline ie completed or underway).
The coat for revegetation can be reduced to 52,818.00 (this is a 50 percent reduction in
the coat of planting trees and shrubs from the Division's previous estimate).
The reductions in the previously estimated reclamation coats yield a new estimated coat of
$158,000.00.
A BOND IN THE AMOUNT OP $158,000.00 MUST BE IN PLACE FOR THIS PIT NO LATER THAN JANUARY 29,
1996.
The operator may either submit a new bond in the full amount of $158,000.00, in which case
the existing bond would be returned, or the operator may submit a rider to the existing bond
to bring the amount held to $158,000.00.
