Dust Sources, Control, and Training

Dust Control


There are three types of sites or activities governed by Maricopa County dust control regulations; traditional dust-generating activities, non-traditional dust-generating activities and gravel, asphalt and related activities. 
  1. Rule 310
  2. Rule 310.01
  3. Rule 316

Traditional Dust-Generating Activities (Rule 310)


Any activity capable of generating fugitive dust (such as construction, earthmoving, demolition, or weed abatement), regardless of the size of the site, must comply with Rule 310 and control potential dust.

In addition, a Dust Control Permit is required by Rule 310 (PDF) for many types of sites, such as:
  • Activities that will disturb a surface area equal to or greater than 0.1 acre
  • Bulk material handling
  • The demolition of buildings
For more information, consult the Dust Abatement Handbook (PDF). You can also watch the Construction Dust Control Video (available in English and Spanish)
