Dust Abatement Program

Winslow Avenue

This multi-year project is in accordance with EPA requirements and part of a larger countywide plan to reduce air pollution.

MCDOT maintains nearly 700 miles of unpaved roads throughout the valley. With the population increasing in our outlying/rural areas, dust suppression has become a major concern as these roads are significantly contributing to the airborne pollution in our dry desert community. MCDOT is committed to you, the citizens, and pledges to continue this aggressive program to reduce our airborne pollution and increase our air quality.

In response to the growing concerns about dust in our dry desert community, the Maricopa County Department of Transportation (MCDOT) has established a dust hotline, (602) 506-DUST (3878). Additionally, residents can ask a question online.

County residents can call the Dust Hotline 24 hours a day with questions about dirt road maintenance or paving. A recorded message will give the caller the latest updates on dust issues and allow the caller to have their questions or concerns recorded. This recorded information will allow a MCDOT staff person to personally return the call.
