• sediment load will be minimal. Any sediment
leaving the area will be filtered by the
dense vegetation between the outslope and
Hubbard Creek.
LH4 The access road to the ventilation portal
area is not protected from any sediment
control method. Sediment load should not
enter state waters from this area due to the
light road use and the gentle slope of the
road. The outslopes of the road along the
Hubbard Creek crossing are rip-raped to
control any erosion and sediment load from
occurring.
Upper Hubbard Creek Facility: (see map E8-3351R)
UH1 Runoff from the topsoil stockpile area flows
through a grassy area to control sediment
load in any stormwater leaving the stockpile.
No erosion should occur in this area due to
its gentle grade and rock lined slopes.
UH2 Sediment in the runoff from the sediment pond
and ventilation pad outslope will be
• controlled by dense vegetation on the slope.
Erosion in this area should not occur due to
the area's dense vegetation.
g. Employee Education: The contents of this stormwater
management plan will be reviewed with necessary
employees on a periodic basis. Particular attention
will be given to: 1) maintaining the sediment fences
and straw bale filters; 2) rill and gully repair; 3)
revegetation procedures; 4) maintaining surface
moisture in coal stockpile and plant roads; 5) cleaning
the paved haul road as necessary.
h. Testing for Non-stormwater: The potential stormwater
discharge points have been evaluated for the presence
of non-stormwater discharges such as mine drainage,
contaminated springs, sanitary waste, or process water
of any kind. The evaluation was performed by the
undersigned. The evaluation was based on a visual
observation of all of the stormwater discharge points.
The inspecti~Jon~occurred on September 27, 1993.
