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.
reach the channel has gullied and there is an active head-cut. The head-cut location is noted on
Photo SL2-48; maintenance is warranted to repair the gully and stabilize the head-cut.
There has been some settling and small slumps along the reclaimed highwall north of the
channel, upstream of the oil well road, in the years since it was regraded, and several locations
have been repaired in recent years and now appear to be stable. A heavy growth of annual brome
was noted in one of the hummocked repair areas, and herbicide treatment may be warranted.
Farther to the west, areas of relatively poor vegetative cover were observed along hillslopes on
both sides of the channel. Recent gully repair work was apparent in a couple locations on the
south hillslope. The broad lower slope areas between 006-NE2 and 006-NE1, which drain
toward the Oil Well Access Road,have been subject to rill and gully erosion and associated
repairs,over several years (Photo SL2-33). These slope areas will need to be monitored following
snowmelt in 2010; further measures including low impact rill repairs and interseeding may
be warrranted in a number of locations on this slope.
Approximately 300' to 500' up-drainage from the oil well road, an apparent settling crack was
observed along the lower portion of the slope north of the channel, running parallel to the
channel for 200 to 300'. The crack was 1-2"wide, and appeared fairly deep in places, although
there was no apparent movement associated with the crack. No action is warranted at this time
but the crack will need to be visually monitored.
Channel 006-NE3
This watershed drains the upper end of the northern "A" Pit reclamation. The drainage is a broad
grassy swale along its upper end, narrowing somewhat along its lower half, where dense shrubby
vegetation dominated by Woods rose and big sagebrush gives the drainage the appearance of a
woody draw. In most areas, the actual channel is not well defined,but the drainage is heavily
vegetated and stable. Photo SL2-25 shows the upper watershed area; Photo SL2-28 is a view up-
drainage from the lower end of the "woody draw"reach.
Along,the broad ridge that separates the 006-NE3 watershed from 006-NE4 and upper NEI, a
long intermittent gully was observed. The gully begins at a point approximately 50 yards west of
the powerline, and continues for several hundred feet,with healed sections interspersed with
sections that exhibit active erosion, in some locations 12-16" deep. A section of the gully along
the ridge west of the power line is shown in Photo SL2-26. This gully will need to be stabilized
in accordance with the approved Rill and Gully Plan in 2010.
