Background
• Construction Entrance/Exit source of
stormwater pollution
• Requires Sediment Control practice
• The purpose of stabilizing entrances to a
construction site is to minimize the amount
of sediment leaving the area as mud and
sediment attached to vehicles

What is Trackout?
• Dirt, mud or other debris tracked onto a
paved public road by vehicle leaving site
• Dirt or mud adhering to the exterior of
vehicle leaving site that falls onto road
• Traces of dirt or other bulk material that
spill onto road from vehicle leaving site
• Dirt or mud leaving unpaved road going
onto paved public roadway

What is trackout?
• Particulate matter (PM10), a regulated air
pollutant, is created when trackout is lifted
back into the atmosphere by vehicles

• Early Phase 1 requirements
• Included sediment control at entrance/exit
• Lead to the common use of crushed rock

Why is Trackout a Problem?
• Soil sediment that leaves the site contributes
to a degradation of water quality
• Identified as source of pollutant
• Carry attached pollutants such as
– Petroleum
– metals,
– Chemicals
– Pesticides
– bacteria

Problem in Los Angeles Metro
• Crushed stone pads not effective
• Sought alternatives
• Effectively remove dirt and debris from
vehicles leaving site

Trackout Plates
• Steel base plate with ribs
• Effective in removal of dirt and debris that
is typically carried out on vehicle wheels
• Flat plate or elevated “grate”

Trackout Plates
• Effectively “open” tire surface to free dirt or
debris from transporting off-site

Design Considerations
• Trackout Plate
– Strength of materials suitable to heavy
construction equipment
– Rib materials and placement
![Page 22: Construction Entrance Sediment Control using · PDF fileConstruction Entrance Sediment Control using Trackout Plates. Background • Construction Entrance/Exit source of ...

Design Considerations
• Site Placement
– At construction entrance/exit
– Sized to accommodate all vehicles
– Size to largest vehicle with room to spare
– Funnel all construction traffic to device
(if you leave space for them to go around it, they
will go around it !)

Design Considerations
• If site entrance leads to paved road, make
end of entrance flared so that long vehicles
remain on device

Maintenance Considerations
• As per EPA recommendations for all BMPs,
maintenance is necessary/required
• Scheduled clearing/sweeping

Effectiveness
• In Los Angeles Metro
• Required on all construction sites
• Reduced trackout
• Other benefits
– Inspectors attracted to site with heavy trackout
– Less complaints from neighbors, damages
– Less maintenance

Where are we at in Region 6?
• In compliance ?
• Still issues, but do we need to do more?
• Inspections
• Enforcement
• Meet standards or is it effective?
