May 16,2011 C-I 982-057/Seneca 11-W Mine SLB
Culvert ME-1 was conveying heavy flows from Dry Creek under the haul road.The outlet end of the culvert was
downcutting approximately 6' at the culvert area and beyond the pen-nit boundary. This area was included in the
citation for Notice of Violation No. CV201 1-00 1, also for failure to ensure that haul roads do not cause"additional
contributions of suspended solids to strearnflow or to runoff outside the permit area"as required by Rule
4.03.1(1)(b).
Road J was in good condition. With a few minor exceptions,the outfalls of the Road J culverts(maintained last
fall)were in good condition. The operator will need to clear the dissipating areas above the silt fences at B
and J4. The inlet side of J4 will also need to be repaired.
The Ridgeline Access Road between the C/D and A/B pits was in good condition. Light Use Roads 3,4,and 5
were not accessible due to muddy conditions.
Light Use Road LU-2 exhibited a gully down its entire length from topsoil stockpile(TSS 1)to the well
pumphouse; the gully was approximately 8"deep and 12"wide. The operator needs to regrade the road(LU-
2) and reestablish a ditch for road surface drainage.
The culvert at the intersection of the Oil Well access road and the 006NE I drainage needed to be cleared on the
inlet side.
Haul Road G and the associated ditches and culverts were in good condition.
REVEGETA TION—Rule 4.15
- Vegetative Cover; Timing.-
The soils were saturated, the temperature was unusually cool and large patches of snow were still present which is
unusual for this time of year making the vegetation late sprouting. The early season forb species were just starting
to flower. Some perennials grasses and fortis were starting to sprout and the shrubs were at bud-break. Some of
the species seen sprouting in the reclaimed areas were alfalfa, western spring beauty,pennycress, alfalfa and
prairie onion. Aspens were breaking-bud within one of the shrub enclosures.
SLIDES and DAMAGE -Rule 4.12:
Several slides were observed on the reclaimed areas:
In the vicinity of Pond 006, (Area 2 on Figure 1), cracks were developing on the inlet slope below the intersection
of MEHR and the Oil Well Access Road. Area 3 is a scarp adjacent to the undisturbed area on the south side of
the lower end of 006 Gulch. Area 4 is a large slide extending from the light use road LU-2 down to Haul Road A
along the undisturbed/disturbed area boundary. Area 5 is a scarp between the facilities yard and Haul Road A.
