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 1 Mine was conducted by DRMS staff from the Durango Office,
located at 701 Camino del Rio, Room 315, Durango, CO 81301, phone [phone]. The King
Coal 2 Mine was not inspected. Operations were active during the time of the inspection.
Trucks were delivering coal from the King Coal 2 Mine. Coal was also being stockpiled at the stacker
tube via the conveyor belt from the King Coal 1 Mine portal.
Mine identification sign and permit boundary markers were posted.
_The large sediment pond, located on the west side of the entrance road, was holding water. The
water and sediment elevation rod was lying on the crest of the pond embankment, awaiting installation
in the pond. Water depth was visually estimated at one foot. The elevation of the water surface was
well below the toe of slope for the pond embankment and approximately five feet below the inlet of the
primary spillway. The primary spillway is augmented by an overflow pipe, which conveys water from
the large sediment pond to the small sediment pond, and byan open-channel emergency spillway.
Evidence of seepage through the pond embankment or discharge from either spillway was not
observed. Portions of the protective vegetative cover for the pond embankment has been buried in
sediment placed on the embankment during the recent clean-out of the pond. The embankment
appeared intact and stable. However, the protective vegetative cover for the embankment is essential
to ensure stability and must be re-established in accordance with permit conditions.
The small sediment pond, located on the east side of the entrance road, was holding water; depth of
water was visually estimated at one foot. The elevation of the water surface was approximately eight
feet below the inlet for the primary spillway. The primary and emergency spillways appeared clear and
functional with no evidence of discharge noted. A minor occurrence of Russian knapweed, a
regulated noxious weed, was observed on the embankment for the small sediment pond and nearby
the outlet of the east upland diversion ditch.
