The inspection <br /> began at the west end of the site at the J pit,where highwall mining that began in January was observed. <br /> Coal hauling coal from J pit was underway. One dragline was idle at the N Pit at the time of inspection. <br /> Several benches exist in the N Pit from west to east. The N Pit floor is exposed on the west end of the Pit. <br /> The coal level has been reached at the west end of the N Pit. There are several seeps along the south and <br /> east walls of the pit that exhibited themselves as ice. Some dust rose out of the N Pit due to spoil hauling <br /> in the dry conditions. It is too cold to water roads.

Machinery was operating at <br /> the east edge of the Pit removing the last knob of overburden. Coal and overburden were being hauled <br /> from L Pit.
