DESCRIPTION(S):

The following are practices that can be used to reduce PM10 emissions:

Access Restriction: restrict public access to unpaved roads using signage or physical access 

restrictions (e.g., access barrier).

End-of-Row Equipment Turnaround Areas: prohibit turning tractors or other implements on 

public paved roadways; 

or clean pavement after practices have ceased.

Paving: pave unpaved roads. (Gives maximum PM10 emissions reductions as long as paved surface 

is kept clean.)

Road Treatments: apply water, mulch, organic materials, polymers, dust suppressants, or wood 

chips to 

the unpaved road surface area.

Speed Limits: control speed limits to 15 mph on unpaved roads through worker behavior 

modification, signage, or any other necessary means.

Surface Modification: Cover unpaved road surfaces with a low silt-content material, such as gravel 

or recycled road base.

Track-Out Area Improvements: minimize dirt material tracked out onto public roadways by paving 

or 

chemically stabilizing, or applying gravel to the unpaved road surface for a distance of at least 100 

feet from the public roadway.

Track-Out Prevention: check or clean the underside of all haul trucks before leaving the parking or 

staging area.

Vegetation: establish natural vegetation on unpaved surfaces no longer being used.
