Pollutant source present? ☐ YES ☐ NO (if NO, skip to next section)
Runoff Conveyances and Diversions
☐	Channel, divert, or capture runoff and transport it to areas where it can be used or released without 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.

☐	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 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.

☐	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.

Pollutant Source 1: Site Preparation  -  Haul/Access Roads (Pre-Construction)
Pollutant source present? ☐ YES ☐ NO (if NO, skip to next section)
☐	Site roads as far as possible from natural drainage areas, lakes, ponds, wetlands, or floodplains.

☐	Design roads to be as small as possible, match the natural contours of the area, and meet regulatory requirements.

☐	Keep as much vegetation as possible.

Pollutant Source 2: Site Preparation  -  Haul/Access Roads (Construction and Post-Construction)
Pollutant source present? ☐ YES ☐ NO (if NO, skip to next section)
Surface Stabilization Measures
☐	Control dust and prevent soil loss as dust by watering, mulching, sprigging, or applying geotextile materials.

☐	For disturbed surfaces (non-roadbed) that will support vegetation, use mulching practices (applying a blanket of plant residue or synthetic material to protect surfaces and to create a matrix for seeding).

☐	Stabilize steep grades with sod if seeding is not conducive.

☐	Temporary and Permanent Seeding:

☐	Temporarily plant rapid‐growing annual grasses, small grains, or legumes in areas that are not to be brought to final grade for more than approximately one month. 

☐	Permanently seed areas that will be covered with vegetative growth for more than two years.

☐	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).

☐	Install riprap in areas prone to erosion, seepage, or poor soil structure (e.g., channel slopes and bottoms, storm water 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.

Runoff Diversion and Sediment Control
☐	Divert runoff from unstabilized road surfaces, minimize erosion, and direct flow to appropriate channels for discharge to treatment areas. Consider installing the following SCMs:

☐	Discharge diversions such as dikes, curbs, and berms.

☐	Conveyance systems such as channels, gutters, culverts, rolling dips and road sloping, and roadway water deflectors.

☐	Runoff dispersion measures such as check dams, rock outlet protection, level spreaders, stream alteration, and drop structures.

    ☐	Sediment control and collection measures such as gabions, riprap, native rock retaining walls, silt fencing, sediment traps/catch basins, and vegetated buffer strips.

☐	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.

Pollutant Source 3: General Site Preparation and Operation
Pollutant source present? ☐ YES ☐ NO (if NO, skip to next section)
Runoff Conveyances and Diversions
☐	Channel, divert, or capture runoff and transport it to areas where it can be used or released without 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. 

☐	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 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, 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.

☐	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).

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 conduit material.

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

☐	For runoff dispersion, use check dams, rock outlet protection, level spreaders, stream alteration, and drop structures.


☐	Direct contaminated flows to sediment ponds or other treatment facilities. Consider the following SCMs:


☐	Conveyance systems such as channels, gutters, culverts, rolling dips and road sloping, and/or roadway water deflectors.

☐	Gabions, riprap, native rock retaining walls, sediment traps/catch basins, and vegetated buffer strips for sediment control and collection.
