Tips to Reduce Fugitive Dust
-
A dust control permit is required on all job sites that will disturb more than 1/10 acre (4356 sqft) of soil.
See Dust Control Permit Applications
for an online application form. Read and know your dust control permit and plan.
-
Implement your dust control plan and ensure that all workers or subcontractors on site understand their
responsibility while on site.
-
Use your contingency dust control measures when primary control measures are ineffective.
-
Prevent dust from exceeding visible emission limitations of 20% opacity. For more information
on visible emissions and certification visit http://www.azdeq.gov/environ/air/compliance/smoke.html
-
Monitor the worksite for compliance with the dust control plan and keep records of dust control method implementation.
The Arizona Department of Transportation, Arizona State University, and Maricopa County Air Quality Department have
partnered together to produce a pamphlet called The
Dust Devil Academy Construction Guide. This guide has useful information concerning the health effects of particulate
matter (dust) and how to control dust producing work operations.
For further information about the Maricopa County dust control regulations, please see
Rule 310,
Frequently Asked Questions, or
Photographs of Common Violations.
Maricopa County’s Rule 310 (Fugitive Dust Sources), Section 502
states that any person who conducts dust generating operations that require a Dust Control Plan shall keep a daily written log recording the actual application or
implementation of the control measures delineated in the approved Dust Control Plan.
In order to better describe what should be included in a daily written log, Maricopa County created samples of daily record keeping logs
for Rule 310.
Provided in the Dust Compliance Resources are three dust log examples. You can use one of these three
samples or you can create your own daily record keeping log for Rule 310. Whichever
format you choose to keep your log in is up to you, but you must keep a daily written log recording the results from inspecting your dust control measures. If you have
further questions about dust control, please call (602) 506-6010 or (602) 372-2703.
