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 partial inspection of the King Coal land 2 Mines was conducted by DRMS staff from the Durango
Office, located at 691 County Road 233, Suite A 2, Durango, CO 81301, phone [phone].
Operations were active at both sites. Five photos of the King Coal 1 Mine accompany this report.

Mine identification sign and permit boundary markers were posted. Grading of the Refuse Disposal
Pile was occurring. Equipment utilized at the RDP included a bulldozer, Cat 815F compactor, and a
324D excavator. As shown in the photos and discussed below, there exist several maintenance
issues at the King Coal 1 Mine needing the Operators attention.
The East Diversion routes upland drainage around the east side of the yard area. As shown in the
photo, a portion of the ditch was partially obstructed by earthen material. Maintenance for the upper
reach of the East Diversion appears necessary to ensure the capacity and continued function of the
structure. Other portions of the East Diversion, consisting of the rock lined channel, buried culvert and
open ditch with sediment sump (lower reach) appeared clear and stable. Debris screen was not
present at the inlet to the buried culvert.
The South Diversion routes upland drainage, generated from the watershed located south of the yard
area, under the yard via a culvert. As shown in the photos, the inlet of the culvert was partially
obstructed by soil sloughing and the outlet of the culvert was partially obstructed by sediment.
Affected area drainage from the upper yard area is conveyed to the West Sediment Pond by a series
of buried culverts. There are three drop-inlets to the culverts located in the upper yard area. As
shown in the photo, the uppermost of the drop-inlets, located nearby the coal conveyor, was not
located and appears to have been buried in sediment and debris. The second of the drop-inlets,
located nearby the shower house, appeared clear and functional; debris screen was intact. As shown
in the photo, the debris screen for the third of the drop-inlets, located nearby the scales and office, has
fallen into the inlet.
The drainage swale in the entrance road, which directs yard drainage to the East Sediment Pond, was
intact. The sediment traps for the portions of the entrance road located outside of the sediment
containment system appeared intact and functional. The East and West Sediment Ponds were
holding water, visually estimated at two foot depth and approximately six feet below discharge levels;
no discharge was observed from either pond. The primary spillways were clear and functional.
