Conveyor C-9 transfers the raw coal to the preparation plant where it enters the wet process. Raw coal is also stockpiled at the facility. Ra w coal is trucked to open stockpile OS2, where it is reclaimed using a front endloader and dumped into the endloader feeder. Clean coal is also conveyed to open stockpile OS2 by conveyor C-14 (see below).
