June 6,2011 C-1994-082/Yoast Mine SLB
Water was observed in Stock Tank T-1,but it was not flowing out of the spillway.
Downcutting was observed,and maintenance necessary, in the upper portion of YPM 11,near culvert YB6
(through Light Use Road LU2),up about 40 feet from the culvert inlet. Rills and gullies were observed in around
the 2003 shrub plot located at the top of YPM-9- YPM-9 and YPM-13 were badly eroded and will need to be
repaired; downcutting in YPM-13 was up to 42"deep in places.
Channel YPM 1-1,the lower end of YPM 11 near Topsoil Stockpile I,YPM 21, and YPM-22 were all in excellent
condition. The majority of the drainages had functioned well during runoff.
ROADS—Rule 4.03 1111 Construction 4.03.1(3)/4.03.2(3)❑❑Drainage 4.03.1(4)/4.03.2(4)❑❑Surfacing and
Maintenance4.03.1(5)and(6)/4.03.2(5) and(6)❑❑Reclamation 4.03.1(7)/4.03.2(7):
Downcutting was observed on the inlet side of culvert YA6;this should be repaired when the operator
repairs the outlet side to abate NOV CV2011002. The downdrain between YA6 and YA7 was also eroding and
should be repaired. Culvert YB3 was nearly plugged and should be cleaned out as soon as possible.
REVEGETATION—Rule 4.15❑❑Vegetative Cover;Timing:
The majority of the vegetation is in excellent condition; observations included Great Basin wildrye,two
types of fescue,wheatgrasses,alfalfa, sage. Arrowleaf balsamroot,yarrow,phlox, larkspur,pennycress, and
lupine were all in bloom.
Thistle,houndstongue, and whitetop were observed in several areas within the permit boundary. Thistle was
observed in the area along the Haul Road A road ditch that drains toward YA-6(where straw wattles have been
placed); below,in, and above the shrub plot at the base of the North Pit area(plot established in 2010 that slid this
spring); in the area near YPM 11 and LU2; around YPM 13,Pond 11 A,and Pond 011; along the eastern side of the
large bare patch in the North Pit. Whitetop was present in patches between culverts YA6 and YA7; at the outfall
of Pond 010; on the west inslope of Pond 010; on the Pond 010 embankment; on Topsoil Stockpile I;below, in,
and above the shrub plot at the base of the North Pit area(plot established in 2010 that slid this spring);just
downslope of the easternmost undisturbed patch immediately downslope of the former location of Topsoil
Stockpile E. Houndstongue was present around YPM013,Pond I IA,and Pond 011.
There is a large bare area in the North Pit reclamation at the former location of Topsoil Stockpile D. The operator
indicated that this area was reseeded last fall. Observations during the inspection indicate that the reseeding effort
failed; there was less than 5%cover,and it appeared that nothing had germinated. The soil was quite dry. The
operator should consider testing this soil to determine why revegetation efforts are failing. The east side of this
patch was very weedy.
SLIDES and DAMAGE -Rule 4.12:
No additional movement was observed to have occurred in the Pond 012 area slides. The inlet area slides
and north sideslope slump were very wet from seeps and springs.
