The pond is visited during NPDES sampling, and the v -notch weir is inspected to determine if it is functioning
correctly. The pond is also inspected quarterly to determine if it is functioning correctly and to assess the condition
of its embankment and spillways. Repairs are made on an as -needed basis. The pond will be removed when it is
no longer needed. The outlet works will be removed and the embankment graded back into the pond excavation,
the area will be final graded so that it blends with surrounding area, and the regarded area will be topsoiled and
seeded.
Pond F receives runoff from the surface facilities, reclaimed surface mine, spoil springs, and underground mine
discharge. TC will inspect Pond F for sediment accumulations in the same manner as described for Treatment
Facility B. The same criteria given will be used to determine if the pond requires cleaning. If so, the material will
be removed and hauled to the refuse pile or pit for disposal. The pond is visited during the periodic NPDES
sampling, and the condition of the measuring device is noted. The current measuring device is a cutthroat flume
located upstream of the road culvert. Problems were encountered with the existing weir, and the weir was replaced
with the 12 -inch cutthroat flume to assure accurate flow measurement. Repairs are made on an as -needed basis.
The pond will be removed when it is no longer needed. The embankment will be graded in and the outlet works
removed. The stone in the spillway will either be reclaimed or placed in the pond excavation as part of the backfill.
The area will be graded to blend with the surrounding topography, then topsoiled and seeded.
Pond G receives runoff from a part of the surface facilities and the reclaimed surface mine. TC will inspect Pond G
for sediment accumulations in the same manner as described for Treatment Facility B. The same criteria given will
be used to determine if the pond requires cleaning. If so, the material will be removed and hauled to the refuse pile
or pit for disposal. The pond will be removed when it is no longer needed. This is also an MSHA pond and subject
to weekly inspections. The outlet works are inspected and repairs made as required. The embankment will be
graded in and the outlet works removed. The stone in the spillway will either be reclaimed or placed in the pond
excavation as part of the backfill. The area will be graded to blend with the surrounding topography, then topsoiled
and seeded.
Pond T receives runoff from the magazine and storage yard area. TC will inspect Pond T for sediment
accumulations in the same manner as described for Treatment Facility B. The same criteria given will be used to
determine if the pond requires cleaning. If so, the material will be removed and hauled to the refuse pile or pit for
disposal. The pond is visited during the NPDES sampling and the weir is checked to see if it is working correctly.
Any problems are noted and repairs made as needed. The pond will be removed when it is no longer needed. The
embankment will be graded in and the outlet works removed. The stone in the emerging spillway will either be
reclaimed or placed in the pond excavation as part of the backfill. The area will be graded to blend with the
surrounding topography, then topsoiled and seeded.
FCB Treatment Facility (Revised - MR07-216)
Three treatment cells were constructed for treating mine discharge water from the Fish Creek Borehole. Tile cells
location and cross-sections are shown on Maps 26 and 32, Fish Creek Borehole Area Facilities, and Access Road,
and Fish Creek Settling Pond Plan View and Cross Sections. The design for the culverts for the Fish Creek
Borehole Access Road is presented in Exhibit 8R.
The facility originally consisted of two adjacent dewatering wells. A water treatment system consisting of three
treatment cells, chemical feed stations (sodium hydroxide and sulfuric acid), a substation, access road and
powerlines, was subsequently added. The facility was modified in 2006, to replace the sodium hydroxide treatment
system with an electro -coagulation unit. In 2007, the inactive Fish Creek Ventilation Shaft was converted to a
dewatering installation to replace the inoperable Fish Creek South Dewatering Borehole. The water supply pumps
are set within the dewatering wells immediately above the top of the coal seam in sealed mine workings in the
Western Mining District. Electricity is supplied by the powerlines shown on Map 39, Powerline Location. Each
borehole is capable of discharging up to 500 gpm of mine water. Discharge through the boreholes will occur on an
alternating basis, with the potential of discharging simultaneously.
