October 4, 2011 C-1982-057/Seneca II-W Mine SLB
North area roads and associated ditches were in good condition. Rainfall the night of October 4th caused
the south area roads to be impassible beyond the PM-41)drainage crossing or Pond 016A.
When the Mine Entrance Haul Road was narrowed earlier this year,the operator excavated a surge pond along the
roadway ditch just upgradient of culvert ME2. This surge pond elevation is too low and is causing water to
impound and not flow through the culvert. This structure should either be allowed to silt in to the elevation of the
culvert inlet, or the pond outlet end will need to be lowered to ensure that water does not flow back onto the road
surface.
The Tie-Across Haul Road surface was in good condition. Culvert TAHRC7 still needs to be armored on the
outfall side.
RE VEGETATION Rule 4.15 Vegetative Cover; Timing:
Approximately 100 head of cattle were grazing the north area, including all of the A/B and C/D pit areas,
ponds, and roadways. Grazing was most apparent on the grasses and alfalfa. Areas seeded this year(narrowed
roadways and shop area reclamation)have germinated;grasses were observed sprouting through the turf
reinforcement mat in the shop area. The operator has planted additional shrubs and trees in areas around Pond 006
and Topsoil Stockpile I.
SLIDES and DAMAGE-Rule 4.12:
Toe drains on the pit ramp slide had not been constructed and will need to be complete before winter sets
in.
Work on the Pond 016A slide remediation was continuing. An excavator was working on PM-2 channel
construction near the embankment of regraded Pond 016A. A bulldozer was grading material from below the
shrub plot and pushing it to Pond 016A. The operator's sheepsfoot compactor had broken down, so material
spreading and compacting was delayed. A scraper was spreading the material around the pond so that when the
compactor was repaired the material would be compacted. It was expected that the compactor would be back on
line late on October 5th. Grading operations below the shrub plot have oversteepened the slope so that it might be
necessary to grade back into the shrub plot for maximum stability. Tension cracks were observed in the upper
slope just below the shrub plot fence.
SIGNS AND MARKERS Rule 4.02:
Permit boundary,mine identification,topsoil stockpile, and stream buffer zone signs and/or markers were
all observed to be appropriately located throughout the site and were in good condition.
