The Maricopa County Air Quality Department’s Dust Compliance Division is responsible for
protecting the public from airborne particulate matter [PM10 and PM2.5].
The Dust Compliance Division is divided into five areas
Fugitive dust from unstable or disturbed dirt surfaces (such as construction areas, vacant lots, dirt roads
and dirt tracked out onto paved surfaces) are the largest man-made contributors to the County’s
non-attainment of the PM10 standard. The Air Quality Department issues Dust Control Permits to citizens
who plan to conduct activities that will disturb a surface area equal to or greater than 0.1 acre or the
demolition of buildings. These permits require the permittee to plan their dust control measures to prevent
the creation of fugitive dust (see Dust Control for details). All
sites with disturbed surface areas, regardless of size, must maintain compliance with Rule 310.
The Division also manages the Residential Woodburning Rule and Ordinance, which is designed to restrict fireplace
use on high pollution days (see Fireplaces for details).
Open Burn Permits are issued to citizens who wish to conduct allowable burning activities. With few exceptions,
open burning is not allowed without an approved permit (see Burning
Activities for details).
Vacant Lots and Unpaved Areas
The Air Quality Dust Control Program also investigates dust complaints concerning vacant lots, open areas,
unpaved parking lots, and commercial livestock areas. Owners are required to use dust control measures on
their properties, such as stabilization media (gravel or vegetation) or preventing trespassers on the property
(see Vacant Lots for details).
Off-Highway Vehicles (OHV)
Nature Rules - Curb Your Dust. Motor vehicle use on unpaved surfaces is limited in Maricopa
County. Before driving, riding, or parking on any land, check with the appropriate agency about the rules and
requirements. You may be subject to fines and penalties if you violate the rules and requirements.

Maricopa County Air Quality does not address dust complaints resulting from agricultural sources. However, The Arizona Department of
Agriculture offers a compliance assistance program for commercial farmers to ensure compliance with laws and rules that address air
quality standards within the Maricopa County PM10 non-attainment area.
