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 Mine 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 the King Coal 1 and 2 mines during the time of the inspection. The sediment
containment systems appeared well maintained and functioning in accordance with design. Evidence
of affected area drainage escaping the permit area prior to treatment was not observed. Five photos
accompany this report.
King Coal 1 Mine
The three sediment sumps,designed to treat road drainage located outside of the sediment pond
containment area, appeared well maintained and functional. The drainage swale in the entrance road,
which directs yard drainage to the east sediment pond, was intact. The Operator has constructed a
safety berm around the east pond and installed a culvert through the safety berm to convey yard
drainage to the pond.
The east and west sediment ponds have been recently cleaned of sediment. Both were holding water,
visually estimated at one foot depth and well below,discharge levels; no discharge was observed from
either pond. The primary and secondary spillways for the east pond were clear and functional, as
were the primary spillway for the west pond and the overflow pipe from the west pond to the east
pond. However, as shown in the photos,the secondary spillway for the west pond needs clean-out to
ensure its continued function in accordance with its approved design.
The ugly buggy, previously identified in the Division's report generated from the June 4, 2008
inspection as a possible obstruction to the inlet of a culvert, had been removed and the culvert inlet
fully cleared.
As shown in the photos, the Operator was extending the French drain for the refuse disposal pile and
has cleaned sediment from the east upland diversion ditch located nearby the refuse disposal pile.
Excavation of the easternmost portion of the refuse disposal pile, necessary for extension of the
French drain, has temporarily disrupted the surface of the refuse disposal pile. However, the Operator
has maintained surface grading of the refuse disposal pile to ensure positive drainage; evidence of
impounded drainage on the refuse disposal pile was not observed.
King Coal 2 Mine
Ditches for the sediment containment system appeared well maintained and functional. The sediment
pond was dry. Topsoil has been salvaged and stockpiled at the north end of the yard area.
