Water stored in the ponding area and water inflows during
construction will be bypassed in accordance with the
requirements of Nucla's NPDES permit. In order to perform the
above remedial compliance work, the water will be pumped
and/or diverted downstream as long as the water gpality does
not exceed Nucla' s effluent limitation requirements in the
NPDES permit. Peabody will notify the appropriate regulatory
agencies in accordance with the bypass notification provision
in Nucla' s NPDES permit.
If the water exceeds the effluent limitations requirements of
the NPDES permit, Peabody will retain the water within the
permit area until it meets effluent limitations requirements
by one or a combination of the following techniques:
1. Pump the water to another sedimentation pond.
2. Evaporation.
3. Utilize the water for dust control within the permit
area.
4. Utilize the water for sprinkler irrigation on the
reclamation areas to increase the soil moisture.
5. Reduce the discharge rate and/or install dentention
structures such as silt fence or hay bales at the
discharge location.
Whether the pond is bypassed or the water is moved away from the
construction area to other areas of the permit area, Peabody will
minimize erosion and comply with the applicable regulations.
Embankment reconstruction will be conducted in compliance with CMLRD
regulations (see Exhibit 13-14). The existing embankment will be
cleared of all organic matter prior to the placement of new fill
material . The placing and spreading of fill material will proceed from
the lowest point on the embankment in horizontal layers of such
thickness as to allow for a minimum compaction of 93 percent of the
standard proctor. Fill material will be free of sod, large roots,
vegetation matter, coal or coal processing waste, and frozen material .
