COMMENTS
This was a partial coal inspection conducted by Jason Musick of CDRMS. Brian Watterson of Twentymile Coal
accompanied the inspection. The weather was showing with substaintail snoiw cover through our the mine site.
This partial inspection focused on the approved activites associated with the refuse disposal areas.
HYDROLOGIC BALANCE -Rule 4.05
Drainage Control 4.05.1, 4.05.2, 4.053; Siltation Structures 4.05.5, 4.05.6; Discharge Structures 4.05.7, 4.05.10;
Diversions 4.05.4; Effluent Limits 4.05.2; Ground Water Monitoring 4.05.13; Surface Water Monitoring 4.05.13;
Drainage —Acid and Toxic Materials 4.05.8; Impoundments 4.05.6, 4.05.9; Stream Buffer Zones 4.05.18:
Due to construction of the CRDA being completed in phases, initial perimeter ditches are constructed as
temporary ditches. Permanent ditches have been designed,but are not constructed due to the initial stages of
CRDA construction. All temporary CRDA ditches were snow-covered at the time of the inspection. No problems
were noted.
The CRDA has been designed with a toe-drain to prevent any significant build-up of hydrostatic pressure within
the pile. The toe-drain is designed to discharge into the Area 41 Pit. The Northern end of the toe-drain has been
covered with refuse. The outlet of the toe drain was snow-covered at the time of the inspection. No problems
were noted.
GENERAL MINE PLAN COMPLANCE:
The longwall continues to operate in the 15LT panel. One coal train was observed during the inspection.
PROCESSING WASTE/COAL MINE WASTE PILES —Rule 4.10 and 4.11
Drainage Control; Surface Stabilization, Placement:
The Coal Refuse Disposal Area(CRDA) Expansion was approved through Technical Revisions 67 and 72. The
CRDA expansion area is the only area in which processing waste is being disposed of at the Foidel Creek Mine.
Refuse was being dumped and stockpiled at the time of the inspection with no spreading or compacting operations
observed. It is typical for the refuse to be stockpiled during the winter month's in-order to dry before compaction.
