Pond 009 was holding water at the discharge level,but was not discharging. The embankment was stable
and vegetated,but there were rodent burrows along the crest. These should be monitored to ensure that the
integrity of the embankment is not compromised.
Pond 015 was discharging clear water;the embankment was stable and vegetated.
Stock pond T24 was dry. T22 was wet but not holding water;the bottom of the pond was densely covered with
cattails and bottlebrush squirreltail grass. T20 was holding water but was not discharging. T3 was dry. T2 held a
little water. T25 held water and was discharging down PM-lA. T26 and T27 both held water.
Pond 005 held water and was discharging. Cattle were on the embankment,which was stable and well vegetated.

ROADS Rule 4.03 Construction 4.03.1(3)14.03.2(3) Drainage 4.03.1(4)14.03.2(4) Surfacing and
Maintenance4.03.1(5) and(6)14.03.2(5)and(6) Reclamation 4.03.1(7)14.03.2(7):
The operator had been doing maintenance work along the Tie-Across Haul Road. Culverts previously
identified as problematic had been addressed with the following exceptions: TAHRC-7 should be armored with
rip rap at the outfall and TAHRC-10 needs to be cleared on the inlet side. Ditches along the road were in good
condition.
Ditches and culverts along Haul Road G were in good condition. The culverts and ditches along Road J were in
good condition with a few exceptions -the silt fence at Culvert J 1 was torn; Culvert J4 silt fence was not keyed in
at the base; and the inlet of Culvert J7 was blocked by gravel and rocks from the road.
Culverts Y-2 (at the shop) and A3 (between stock pond T2 and the shop)need to be cleared;there were a few
inches of sediment in the bottom of both.
RE VEGETATION—Rule 4.15 Vegetative Cover; Timing:
Vegetation along the reclaimed G Road corridor is coming along very nicely. There is good cover of
grasses and forbs and a fairly dense stand of sagebrush and rabbitbrush. This corridor has markedly fewer weeds
than the maj ority of the reclaimed mining areas.
