III. COMMENTS - COMPLIANCE
Below are comments on the inspection. The comments include discussion of observations made during
the inspection. Comments also describe any enforcement actions taken during the inspection and the
facts or evidence supporting the enforcement action.
This was a partial inspection conducted by Janet Binns of the Colorado Division of Reclamation, Mining
and Safety(DRMS). Scott Wanstedt of Blue Mountain Energy(BME) accompanied the inspection and
represented the operator. The mine is an active underground longwall mine. The operation is currently
in the process of moving the longwall from LWB-10 to LWB-11. At the time of the inspection, no coal
was being transported along the conveyor to the slot storage building. The weather was mild and dry,
clouding up and sprinkling in the afternoon. The mine site was dry at the onset of the inspection.
Roads: The haul roads and access roads throughout the mine site were dry. Little traffic was observed
along the roadways. The operator noted that BME would be applying MgCl to the roadways soon.
MgCl is applied twice a year. Several piles of gravel were on the haul road to the refuse areas, ready to
be spread upon the haul road. No problems were identified with the roads.
Signs and Markers: BME has mine id signs at entrances from public roadways. Topsoil stockpiles are
denoted with a PVC with a sticker labeled"topsoil". Disturbance area markers are still being discussed
between DRMS & BME. Currently perimeters of degas borehole pads and nitrogen injection hole pads
are not marked.
Hydrologic Balance:
The Division approved MR143 on 4/15/2010. This revision approved placement of a concrete sump for
placement of a pump on the north side of the Raw Water Lagoon. BME has the concrete vault on site.
Excavation for placement of the sump has not been initiated. BME plans to place the vault in an area
that had previously been disturbed. This location is adjacent to disturbance for a buried waterline.
Refuse pile ponds RP-5, RP-4,RP-2/3, and RP-1 were observed. RP-5 was holding water several feet
below the discharge level of the spillway. RP-4 pond was holding water a couple feet below the
discharge elevation on the riser. RP-2/3 pond is composed of three cells. The two side cells contained 1
pools of water. The central cell with the riser& spillway held a small pool of water several feet below
the discharge elevation. Pond RP-1 was dry. No problems were noted with these ponds. Pond DP1 was
holding a pool of water a good foot or more below the discharge level. No problems were noted with
this pond.
Scott indicated that mine water in the D seam will need to be pumped in the future. BME is anticipating
this necessity and is looking at treatment of the mine water prior to discharge to Red Wash. BME also
anticipates the need to discharge mine water from the B seam to an unnamed tributary to Red Wash
located near the east end of LW panel 13 (as the mains pass under the conveyor). BME will be
submitting a revision to the permit to manage this projected discharge.
Processing waste: The refuse piles were inspected. During the winter months BME has placed refuse
on the 5A pile to allow this material to dewater. End dumped piles from this spring were stored on
Refuse Pile 5A. BME was in the process of spreading and compacting this stockpiled material. Refuse
pile ditches are functioning well and directing flows to the appropriate ponds. Refuse pile 2/3/4 was not
