Bulk Material Handling
These photographs show front-end loaders dumping dirt into haul trucks. No dust control methods are being used.
These trucks are leaving a construction site without a tarp covering their load. This is a violation
of Maricopa County Air Quality Rule 310.
When work sites exit onto a paved roadway it is required to install trackout control devices to help prevent particulate matter from adhering to the
tires and exterior surfaces of vehicles. When trackout exceeds a cumulative distance of 25 feet or more it is required to be cleaned-up immediately.
Apply water before, during, and after weed abatement by discing or blading. Also limit visible emissions to 20% opacity.
Example of opacity readings in a grayscale
Vacant lots and open areas are required to be stabilized against fugitive dust emissions. Some control measures to stabilize an area include
preventing access to motor vehicles, installing vegetative cover, applying surface gravel, or applying a dust suppressant to disturbed areas.
See Maricopa County Rule 310.01 for more information.
