of snowfall in recent days. Snow within the King 11 surface facilities was melting, resulting
in wet to muddy conditions under foot. The melting snow provided us with an excellent
opportunity to observe the various collection ditches in action. Site ditches and culverts are
shown on Permit Map King 11-007A.
• Relatively small but steady flows were entering the King II Sediment Pond via culverts C6
and C7. The water level in the pond was low, and a portion of the pond bottom was covered
with ice and snow (Photo 3).
• Culvert C6 carries runoff which originates from the western portion of the King 11 site, while
the eastern fork drains to Culvert C7. During the inspection, we observed that each of the
culverts and ditches was flowing unobstructed (Photos 4 and 5).
• The West Clearwater Diversion Ditch was snow-covered throughout its length. The East
Clearwater Diversion Ditch was predominantly covered with snow, and a segment of the
ditch, northeast of the screen tower, had ponded water due to the low gradient of the flow
line (Photo 6).
• The East and West ponds at King I were both frozen over.
ROADS —Rule 4.03
Construction 4.03.1(3) /4.03.2(3); Drainage 4.03.1(4)/4.03.2(4); Surfacing and Maintenance
4.03.1(5) and (6)/4.03.2(5) and (6); Reclamation 4.03.1(7)/4.03.2(7):
• Due to the melting snow, the roads were wet to muddy throughout the King II facilities area.
• At King I, the road had been plowed from the entrance only to the bath house.
SUPPORT FACILITIES -Rule 4.04:
• Installation of the new permanent screen unit resulted in numerous pieces of equipment being
temporarily mobilized to the King 11 facilities. While the defective screen was being
dismantled and the new screen was being installed, a portable screen, along with a set of
portable conveyors (Photo 7), was utilized to transport coal from Coal Stack Tube 91 to the
Coal Stack Tube#2 storage pile. This array appeared to be in the process of being
dismantled at the time of the inspection.
• The contractor who installed the new screen also had equipment temporarily on site. We
observed welding units being loaded onto a truck for removal from the mine site. A
temporary tank of dyed diesel fuel, with a livestock tank functioning as secondary
containment(Photo 8), was located at the northeast corner of the sediment pond, and will
presumably removed in the near future.
• The temporary screen did not have the capability to crush the larger lumps of coal, so all of
the oversized material that accumulated while the temporary screen was in use was
stockpiled around the perimeter of the Coal Stack Tube#1 pad (Photo 9). This material will
be fed through the new screen as time allows.
• Behind the fuel storage building at King 11, a sump has been previously excavated to contain
runoff from the building site and thereby prevent petroleum products from being immediately
transported across the facilities area. During this inspection, surface runoff was flowing into
this sump (Photo 10). The water in the sump appeared to be substantially free of petroleum
contaminants; no oily sheen was visible on the surface.
