d. Mining at the site will expose groundwater. Given this, the Division needs to
hold a bond to cover the cost of either backfilling the pit to a point above the
water table or a cost to isolate the pit from groundwater inflow by either
installing a clay liner or slurry wall. Given LRM's choice of the installation of
a clay liner as part of the proposed mining and reclamation plan, please
provide the information necessary to conduct an estimate of the cost for the
installation of the proposed clay liner assuming mining stops at the end of
Phase H. This cost should include the cost for placing and compacting the
clay material in lifts and for quality control measurements to insure the clay
material is installed at the proper compaction specification. Since the
material to construct the liner is found onsite, please also include a cost of
excavating the necessary material.
e. Please provide the information necessary to calculate the cost of the
installation of the French Drain and riser system.
f. Please provide the anticipated maximum length of highwall to be in place at
any given time during mining of Phase 1 and II. Please provide an estimate of
the volume needed to grade this highwall to the proposed 3H:1 V slope.
g. Please provide a basis for the pit pumpdown costs.
h. Please provide an estimate of the volume of topsoil to be replaced.
i. Regarding revegetation costs,please provide an estimate of.•
