The following are practices that can be used to reduce PM10 emissions: Access Restriction: restrict public access to unpaved traffic
areas using signage
or physical access restrictions (e.g., access barrier). Paving: pave unpaved traffic areas. (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 traffic surface area. Speed Limits: control speed limits to 15 mph on unpaved areas through worker
behavior modification, signage, or any other necessary means. Surface Modification: Cover unpaved surfaces with a low silt-content
material, such as gravel or recycled road base. 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. Wind Barrier: plant trees or establish other barriers on the typically upwind
side of the traffic area to minimize windblown dust from the unpaved surface. Please note that many of the documents listed are
