~ Stabilize soil with willow cuttings.



~ For areas with mildly graded slopes, apply a
loose, rich, biologically active soil (facilities can
stockpile topsoil for future site use).

poor soil structure (e.g., channel slopes and
bottoms, stormwater structure inlets and outlets,
slope drains, streambanks, shorelines), or where
vegetation cannot be sufficiently established.



~ Establish a graveled area or pad on which vehicles
can drop their mud and sediment before entering
onto roadways.

erosion or flood damage by installing temporary or
permanent structures such as:



~ Level spreaders designed to convert

concentrated runoff to sheet flow for dispersion
across a uniform slope that is not susceptible to
erosion. The outlet lip of the spreader must also
be leveled. To avoid the formation of a gully,
incorporate hardened structures, stiff grass
hedges, or erosion-resistant matting.

Reason Why Inappropriate / Not Done

~ Graded surfaces to redirect sheet flow.



~ Dikes, curbs, and berms that direct surface
runoff around a protected area or prevent it
from contacting sources of pollutants.



~ Conveyances that intercept, collect, and
redirect runoff.



~ Temporary diversions on the down-gradient
end of excavated channels or swales. Such
diversions may be constructed by creating a
dike of spoil materials or gravel.



~ Permanent diversions to divide specific

drainage areas when larger runoff flows are
expected. Such diversions are sized to capture
and carry a specific magnitude of design
storm.



~ Convey runoff via grass-lined channels.
Channels must be established and rooted
before flows are introduced and lining of the
channels is required if design flows are to
exceed 2 cubic feet per second (cfs).



~ In places with steeply graded slopes,

prolonged flow, potential for traffic damage,
erodible soils, or design velocity exceeding 5
cfs, convey runoff via hardened conduits or
ditches (flumes). Flumes should be lined with
structural materials such as riprap or paving.
Additional flume elements include an energy
dissipation feature to reduce erosion/scouring
at the outlet, and an inlet bypass that routes
extreme flows away from the flume.

Appendix Q - Stormwater Control Measure

Stormwater Control Measures: Sector G - Metal Mining (Ore Mining and Dressing) Facilities

SCMs

Reason Why Inappropriate / Not Done

~ Convey concentrated runoff down a cut or fill
slope via a temporary slope drain, until
establishment of more permanent measures
(e.g., stabilization with vegetation) occurs.
Such slope drains are temporary structures
constructed of flexible tubing or similar conduit
material.



~ Reduce outlet flow velocity and dissipate flow
energy via outlet stabilization structures such as
riprap-lined aprons, riprap stilling basins, and plunge
pools. These are used at the outlet of a channel or
conduit where the discharge velocity exceeds that
of the receiving area.



Sediment Traps and Barriers

~ Form a temporary sediment barrier ("brush barrier")
across or at the toe of a slope susceptible to
erosion. Such brush barriers may consist of limbs,
weeds, vines, root mats, rock, or other cleared
materials.



~ Install permanent check dams across drainageways
(not live streams) to restrict flow velocity and reduce
channel erosion. Such dams gradually accumulate
sediment until they are completely filled. Dams may
either be nonporous or porous (the latter will
decrease the head of flow over spillways by
releasing part of the flow through the actual
structure).



~ Construct grade stabilization structures to reduce
channel grade in natural or constructed channels to
prevent erosion. This includes vertical-drop
structures, concrete or riprap chutes, gabions, or
pipe-drop structures. In areas with large water flows,
use concrete chutes or vertical-drop weirs
constructed of reinforced concrete or sheet piling
with concrete aprons. For areas with small flows, use
prefabricated metal-drop spillways or pipe overfall
structures.

SCMs

Reason Why Inappropriate / Not Done

~ Reduce the velocity of sheet flows with silt fencing
and/or straw bale barriers. To control temporary
ponding, provide overflow outlets and sufficient
storage area.



~ At outlets of diversion channels, slope drains, or
other runoff conveyances that discharge sediment-
laden water, install sediment traps (small, temporary
ponding basins formed by an embankment or
excavation). Traps should be designed to minimize
the potential for short circuiting. Include features
such as embankment protection and non-erosive
emergency bypass areas and provide for periodic
maintenance.



~ Filter out sediment around storm drain inlets by

installing temporary concrete block and gravel inlet
barriers.



~ Trap sediment around a storm drain inlet or curb by
excavating a temporary drop inlet. This allows the
permanent inlet to be used before soils in the area
are stabilized.



~ Place temporary fabric drapes around a drop inlet
to protect storm drains. This practice can be used in
combination with other temporary inlet protection
devices.



~ When soils in the area are stabilized, protect a storm
drain drop inlet by installing a grass sod sediment
filter area around it (suitable for the lawns of large
buildings).



~ To filter solids from sheet flow on areas with relatively
flat slopes, vegetate with strips of dense-culmed,
herbaceous, erosion-resistant plants. Vegetated filter
strips (VFS) are more effective if channelized flows
are absent. However, the main factors influencing
removal efficiency are vegetation type and
condition, soil infiltration rate, and flow depth and

travel time. Level spreaders are often used to
promote even distribution of runoff across the VFS.



~ To settle out sediment from runoff, construct

sediment detention basins (either permanent pool or
flow through). To maximize the basin's "trap
efficiency," the following parameters affect the
performance of a basin: particle size distribution of
sediments; detention storage time; reservoir shape,
amount of dead storage, and turbulence; and
water chemistry.



~ To aid the performance of a detention basin, use
flocculants (compounds that create larger particles
that have greater settling velocities). Flocculants
can be useful when a large proportion of entrained
sediment is clay, fine silt, or colloidal materials.
Colloidal materials will remain in suspension and will
not settle out even under quiescent conditions.



Runoff Control and Conveyance Measures

~ In areas with steeply graded slopes, prolonged flow,
potential for traffic damage, erodible soils, or design
velocity exceeding 5 cfs, convey runoff via
hardened conduits or ditches (flumes) Flumes should
be lined with structural materials such as riprap or
paving. Additional flume elements include an
energy dissipation feature to reduce
erosion/scouring at the outlet, and an inlet bypass
that routes extreme flows away from the flume.



~ Convey concentrated runoff down a cut or fill slope
via a temporary slope drain, until more permanent
measures (e.g., stabilization with vegetation)are
established. Such slope drains are temporary
structures constructed of flexible tubing or similar

hardened structures, stiff grass hedges, or

~ Graded surfaces to redirect sheet flow.



~ Dikes, curbs and berms that direct surface
runoff around a protected area or prevent
it from contacting sources of pollutants.



~ Conveyances that intercept, collect, and
redirect runoff.



~ Temporary diversions on the down-

gradient end of excavated channels or
swales. Such diversions may be
constructed by creating a dike of spoil
materials or gravel.



~ Permanent diversions to divide specific
drainage areas when larger runoff flows
are expected. Such diversions are sized to
capture and carry a specific magnitude of
design storm.



~ Convey runoff via grass-lined channels.
Channels must be established and rooted
before flows are introduced and lining of
the channels is required if design flows are
to exceed 2 cubic feet per second (cfs).



~ In places with steeply graded slopes,
prolonged flow, potential for traffic
damage, erodible soils, or design velocity
exceeding 5 cfs, convey runoff via
hardened conduits or ditches (flumes).

Flumes should be lined with structural
materials such as riprap or paving.
Additional flume elements include an
energy dissipation feature to reduce
erosion/scouring at the outlet, and an inlet
bypass that routes extreme flows away
from the flume.



~ Convey concentrated runoff down a cut
or fill slope via a temporary slope drain,
until establishment of more permanent
measures (e.g., stabilization with
vegetation) occurs. Such slope drains are
temporary structures constructed of
flexible tubing or similar conduit material.



~ Reduce outlet flow velocity and dissipate flow
energy via outlet stabilization structures such as
riprap-lined aprons, riprap stilling basins, and
plunge pools. These structures are used at the
outlet of a channel or conduit where the
discharge velocity exceeds that of the
receiving area.



Sediment Traps and Barriers

~ Form a temporary sediment barrier ("brush
barrier") across or at the toe of a slope
susceptible to erosion. Such brush barriers may
consist of limbs, weeds, vines, root mats, rock, or
other cleared materials.



~ Install permanent check dams across

drainageways (not live streams) to restrict flow
velocity and reduce channel erosion. Such
dams gradually accumulate sediment until they
are completely filled. Dams may either be
nonporous or porous (the latter will decrease
the head of flow over spillways by releasing
part of the flow through the actual structure).

~ Construct grade stabilization structures to
reduce channel grade in natural or
constructed channels to prevent erosion. This
type of structure includes vertical-drop
structures, concrete or riprap chutes, gabions,
or pipe-drop structures. In areas with large
water flows, use concrete chutes, or vertical-
drop weirs constructed of reinforced concrete
or sheet piling with concrete aprons. For areas
with small flows, use prefabricated metal-drop
spillways or pipe overfall structures.



~ Reduce the velocity of sheet flows with silt
fencing and/or straw bales. To control
temporary ponding, provide overflow outlets
and sufficient storage area.



~ At outlets of diversion channels, slope drains, or
other runoff conveyances that discharge
sediment-laden water, install sediment traps
(small, temporary ponding basins formed by an
embankment or excavation). Traps should be
designed to minimize the potential for short
circuiting. Include features such as
embankment protection and non-erosive
emergency bypass areas, and provide for
periodic maintenance.



~ Filter out sediment around storm drain inlets by
installing temporary concrete block and gravel
inlet barriers.



~ Trap sediment around a storm drain inlet or
curb by excavating a temporary drop inlet. This
allows the permanent inlet to be used before
soils in the area are stabilized.

Reason Why Inappropriate / Not Done

~ Place temporary fabric drapes around a drop
inlet to protect storm drains. This practice can
be used in combination with other temporary
inlet protection devices.



~ When soils in the area are stabilized, protect a
storm drain drop inlet by installing a grass sod
sediment filter area around it (suitable for the
lawns of large buildings).



~ To filter solids from sheet flow on areas with
relatively flat slopes, vegetate with strips of
dense-culmed, herbaceous, erosion-resistant
plants. Vegetated filter strips (VFS) are more
efficient if channelized flows are absent.
However, the main factors influencing removal
efficiency are vegetation type and condition,
soil infiltration rate, and flow depth and travel
time. Level spreaders are often used to
promote even distribution of runoff across the
VFS.



~ To settle out sediment from runoff, construct
sediment detention basins (either permanent
pool or flow through). To maximize the basin's
"trap efficiency," the following parameters
affect the performance of a basin: particle size
distribution of sediments; detention storage
time; reservoir shape, amount of dead storage,
and turbulence; and water chemistry.



~ To aid the performance of a detention basin,
use flocculants (compounds that create larger
particles that have greater settling velocities).
Flocculants can be useful when a large
proportion of entrained sediment are clay, fine
silt or colloidal materials. Colloidal materials will
remain in suspension and will not settle out even
under quiescent conditions.

hardened structures, stiff grass hedges, or

~ Graded surfaces to redirect sheet flow.



~ Dikes, curbs, and berms that direct surface
runoff around a protected area or prevent
it from contacting sources of pollutants.



~ Conveyances that intercept, collect, and
redirect runoff.



~ Temporary diversions on the down-

gradient end of excavated channels or
swales. Such diversions may be
constructed by creating a dike of spoil
materials or gravel.



~ Permanent diversions to divide specific
drainage areas when larger runoff flows
are expected. Such diversions are sized to
capture and carry a specific magnitude of
design storm.



~ Convey runoff via grass-lined channels.
Channels must be established and rooted
before flows are introduced and lining of
the channels is required if design flows are
to exceed 2 cubic feet per second (cfs).



~ In places with steeply graded slopes,
prolonged flow, potential for traffic
damage, erodible soils, or design velocity
exceeding 5 cfs, convey runoff via
hardened conduits or ditches (flumes).

Reason Why Inappropriate / Not Done

Flumes should be lined with structural
materials such as riprap or paving.
Additional flume elements include an
energy dissipation feature to reduce
erosion/scouring at the outlet, and an inlet
bypass that routes extreme flows away
from the flume.



~ Convey concentrated runoff down a cut
or fill slope via a temporary slope drain,
until establishment of more permanent
measures (e.g., stabilization with
vegetation) occurs. Such slope drains are
temporary structures constructed of
flexible tubing or similar conduit material.



~ Reduce outlet flow velocity and dissipate flow
energy via outlet stabilization structures such as
riprap-lined aprons, riprap stilling basins, and
plunge pools. These are used at the outlet of a
channel or conduit where the discharge
velocity exceeds that of the receiving area.



Sediment Traps and Barriers

~ Form a temporary sediment barrier ("brush
barrier") across or at the toe of a slope
susceptible to erosion. Such brush barriers may
consist of limbs, weeds, vines, root mats, rock, or
other cleared materials.



~ Install permanent check dams across

drainageways (not live streams) to restrict flow
velocity and reduce channel erosion. Such
dams gradually accumulate sediment until they
are completely filled. Dams may either be
nonporous or porous (the latter will decrease
the head of flow over spillways by releasing
part of the flow through the actual structure).

~ Construct grade stabilization structures to

includes vertical-drop structures, use concrete
or riprap chutes, gabions, or pipe-drop
structures. In areas with large water flows,
concrete chutes, or vertical-drop weirs
constructed of reinforced concrete or sheet
piling with concrete aprons. For areas with small
flows, use prefabricated metal-drop spillways,
or pipe overfall structures.



~ Reduce the velocity of sheet flows with silt
fencing and/or straw bales. To control
temporary ponding, provide overflow outlets
and sufficient storage area.



~ At outlets of diversion channels, slope drains, or
other runoff conveyances that discharge
sediment-laden water, install sediment traps
(small, temporary ponding basins formed by an
embankment or excavation). Traps should be
designed to minimize the potential for short
circuiting. Include features such as
embankment protection and non-erosive
emergency bypass areas and provide for
periodic maintenance.



~ Filter out sediment around storm drain inlets by
installing temporary concrete block and gravel
inlet barriers.



~ Trap sediment around a storm drain inlet or
curb by excavating a temporary drop inlet. This
allows the permanent inlet to be used before
soils in the area are stabilized.

Reason Why Inappropriate / Not Done

~ Place temporary fabric drapes around a drop
inlet to protect storm drains. This practice can
be used in combination with other temporary
inlet protection devices.



~ When soils in the area are stabilized, protect a
storm drain drop inlet by installing a grass sod
sediment filter area around it (suitable for the
lawns of large buildings).



~ To filter solids from sheet flow on areas with
relatively flat slopes, vegetate with strips of
dense-culmed, herbaceous, erosion-resistant
plants. Vegetated filter strips (VFS) are more
effective if channelized flows are absent.
However, the main factors influencing removal
efficiency are vegetation type and condition,
soil infiltration rate, and flow depth and travel
time. Level spreaders are often used to
promote even distribution of runoff across the
VFS.



~ To settle out sediment from runoff, construct
sediment detention basins (either permanent
pool or flow through). To maximize the basin's
"trap efficiency," the following parameters
affect the performance of a basin: particle size
distribution of sediments; detention storage
time; reservoir shape, amount of dead storage,
and turbulence; and water chemistry.



~ To aid the performance of a detention basin,
use flocculants (compounds that create larger
particles that have greater settling velocities).
They can be useful when a large proportion of
entrained sediment are clay, fine silt, or
colloidal materials (the latter will remain in
suspension and will not settle out even under
quiescent conditions).
