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.
1 channel (Photo#485). Upon re-inspection on August 12, 2009, the remnant scraper route and
topsoil berm had been properly graded out and the re-disturbance areas had been seeded,but the
areas of minor hillslope erosion down-slope of the volunteer aspen patch and adjacent to the
upper segment of Channel PM 1-1 had not yet been stabilized. The hillslope gully features in
the upper YPM 1-1 watershed will need to be stabilized in accordance with the Rill and
Gully Plan of the approved permit.
Mr. Patrick had also mentioned a concern with weeds in the vicinity of the volunteer aspens.
Although a diverse stand of seeded perennial vegetation is becoming established in the upper
portions of the YPM 1-1 watershed (Photo#477),there is a significant presence of the noxious
weed Canada thistle in the immediate vicinity of the aspen patch(Photo#478). The thistle
patch will need to be treated in accordance with the weed control plan of the approved
permit.
Further down along the YPM 1-1 watershed, a hillslope gully was noted along the north
boundary of Shrub Plot SP06-1, continuing for a distance parallel to the permanent channel. The
gully warrants maintenance/stabilization in accordance with the approved Rill and Gully Plan
(Photos #489/492/493). An old settling crack with maximum displacement of 12-15 inches was
observed on the east facing slope a short distance to the north of Shrub Plot SP06-1. The crack
and small slump feature associated appear to have stabilized, and seeded vegetation is well
established(Photo#491). No remedial action appears to be warranted at this time. The YPM
1-1 channel itself appeared stable along its length down to Stock Pond ST-1. Minor rilling was
present along the west bank of the channel, apparently associated with runoff concentrated along
a maintenance route(Photo#496). Installation of a series of small water bars or similar
maintenance measures to route flow into the channel appear to be warranted. Stock Pond ST-1
contained a shallow puddle; the embankment has not yet been topsoiled and rills have developed.
The embankment needs to be topsoiled and seeded. ST-1 was not included in the SL-2 release
request area.
YPM 5-1 Drainage
YPM 5-1 Channel was walked beginning at its lower end at the inlet to recently constructed
Sedimentation Pond 012A. Pond 012A and its immediate vicinity, including YPM 6-2, YPM 6-
3, Sedimentation Pond 012 and slope failure area north and east of Pond 012 were not included
in the SL-2 release request. YPM 5-1 and its watershed upstream of Pond 012 were included in
