embankment. The operator needs to monitor this situation and ensure that the integrity of the dam is not
compromised. The rip rap in the emergency spillway of Pond 005 has weathered and will need to be replaced to
meet design standards.
Pond 009 held water but was not discharging. The embankment was stable and vegetated,but there was quite a bit
of thistle on and around the embankment.
Pond 015 was discharging clear water at approximately 2-3 gpm. The embankment, inlet,and outlet were stable
and vegetated.
Pond 017 was discharging clear water. The embankment was stable and vegetated,but there is also a considerable
amount of thistle on this embankment.
ROADS—Rule 4.03 L]f]Construction 4.03.1(3)/4.03.2(3)❑❑Drainage 4.03.1(4)/4.03.2(4)110 Surfacing and
Maintenance4.03.1(5)and(6)/4.03.2(5)and(6)0❑Reclamation 4.03.1(7)/4.03.2(7):
The operator was regrading Haul Road A to downsize it to the approved postmining width. Grading was
observed between the shop area and the north side of Pond 006.
An excavator was working in the Road J culvert outlets(J-1, -3, -4, -5, -6,and-7)during the inspection. The
operator installed new silt fence at each outlet,excavated a small sump in front of each fence,and installed rip rap
at some of the culvert outfalls. The silt fence installation was good;the rip rap consisted of large(24"-30")
boulders with no gradation to smaller material. If these channels are not stable through the spring runoff,the
operator should consider reinstalling the rip rap with a gradation of material.
Culvert Y-2,at the shop entrance,needs to be cleaned out; some sediment has accumulated at the outlet end.
Culvert G-5 needed to be cleaned out and the ditch needed maintenance. The operator indicated, after the close of
the inspection,that maintenance at this culvert was underway on October 21,2010.
The Tie Across Haul Road was regraded during the inspection. The road surface and ditches were in good
condition.
SLIDES and DAMAGE -Rule 4.12:
The Pond 016 slide area was saturated,with ponded water throughout. The operator had cut a channel to
drain the water from the Haul Road J roadway and from within the slide itself. It appeared that there was a
considerable amount of groundwater flowing through the slide area.
The operator indicated that they will likely proposed removal of all of the slide material adjacent to Pond 016,
installation of underdrains at the toe of the slide,regrading/reclamation of Pond 016,and relocation of Road J to
remediate the most recent slide. The operator will be resubmitting the revision(initial submittal was incomplete)
for the slide remediation plan.
