This was a partial coal inspection conducted by Jason Musick of the Colorado Division of

site was dry during the on-the-ground inspection. Jerry Nettleton of Twentymile Coal Company
accompanied the inspection.
The longwall mining was operating as permitted in panel 24 in the northern mining district at the time
of the inspection. Development mining was being conducted in panels 16 left and 17 left in the
western mining district. No drilling activities were in progress during the inspection. Coal was not
being loaded out onto trains, although a -103 car train arrived at the site during the inspection.
Roads
Haul roads and access roads were stable and in good condition at the time of the inspection. Roads
in and around the facilities areas were being watered at the time of the inspection. Roadside ditches
throughout the facilities area were stable and no problems were noted. Roadside ditch E-2-B near
the Fan and Utility Building identified on Map 24 was in the process of cleaning at the time of the
inspection.
Hydrologic Balance
Ponds G, F, E, C, B, D, and 6MN were observed during the inspection. Pond 61VIN was holding runoff
water with no pumping occurring. Pond D was discharging and water was flowing from Pit 1 to Pond
D. All Ponds embankments were stable and well vegetated at the time of the inspection.
No discharge was occurring from the Fish Creek Bore Hole ponds. Extra piping and non-coal waste
should be cleaned up in and around the area of the ponds.
The sump on the north side of the access ramp at Pond B appeared to be stable and functioning as
designed with no problems noted.

Waste material placement was being conducted at the time of the inspection. The refuse areas were
stable and appeared to be stable with no problems noted. The RDA 100-year ditch on the north side
of the refuse pile will be addressed within the week of this inspection according to Jerry Nettleton. No
other problems were noted in regard to the ditches directed from the refuse area to Pond D.
Support Facilities
The construction at the 18LT ventilation shaft pad area continues with no problems noted. Erosion
control structures appeared to be functioning as designed. Both boreholes were in the process of
drilling with no problems.
Rock dust tanks N of CR 27 appeared to have some dust spillage evident. Jerry Nettleton mentioned
that new dust collectors have been obtained and need to be installed. The spilled dust will need to be
addressed.
