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. For dust control permit applications, see the Dust Control tab on our Permits, Forms, and Applications page.
  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 sources of 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 .10 acre (4,356 square feet)
  • Bulk material handling
  • The demolition of buildings

For assistance with dust recordkeeping requirements, see our dust control log samples and templates on our Instructions, Handbooks, and Brochures page.
