  • Fugitive Dust

    Fugitive dust is particulate matter which becomes airborne, is not emitted from a stack or vent, and has the potential to adversely affect human health or the environment. High levels of dust particles often originate from agricultural, mining, construction and manufacturing activities. PDEQ protects air quality by regulating fugitive dust emissions and inspecting dust-producing activities and sites. The Fugitive Dust Activity Permit Program ensures that those involved in activities likely to generate dust are aware of fugitive dust regulations and requires them to provide information regarding the location and types of dust-generating activities.

    Who needs a Fugitive Dust Activity Permit?

    Find out if your construction or other activity requires a Fugitive Dust Activity Permit by reviewing Pre-Application Guidance in the tab below.

    How to apply for a Fugitive Dust Activity Permit

    If your work requires a Fugitive Dust Activity Permit, you can apply for the permit online, in person, or by mail/fax. Cash, check, debit/credit Mastercard and Visa are accepted forms of payment.

    Permit Expiration

    Your permit expires one year after being issued. If additional work still needs to be done on the project at the time of permit expiration, a new permit must be obtained for the remaining work if it exceeds the thresholds requiring a permit.

    Permit Termination

    When the permitted work is completed, please print, complete and submit the Voluntary Permit Termination Form to PDEQ to terminate your permit.

    How much does the permit cost?

    Permit fees are based on the type and quantity of work conducted for each project, and can be determined from the Fee Schedule & Definitions.

    What are the Fugitive Dust Rules?

    Even if you don't need a Fugitive Dust Activity Permit for your work, you still must maintain controls for dust during activities likely to create dust. Find out what your responsibilities are by reading the Fugitive Dust Rules contained in Pima County Code Title 17.

    Report a Complaint

    If you are observing excessive dust without controls, dust crossing property boundaries or other dust issues subject to Pima County Code Title 17, you may File a Complaint with PDEQ.

    Pre-Application Guidance

    Are you planning to conduct:

    • Earthmoving or Land Clearing over 1 acre
    • Trenching over 300 feet for utility installation or repair
    • Road construction over 50 feet 
    • Blasting

    If any of the above apply, a Fugitive Dust Activity Permit is required from the Pima County Department of Environmental Quality (PDEQ).  

    Does this activity involve a demolition or renovation of an existing structure?

    "Demolition" means the wrecking or taking out of any load-supporting structural member of a facility together with any related handling operations or intentional burning of any facility.
    "Renovation" means altering a facility or one or more facility components in any way, including the stripping or removal of RACM from a facility component. Operations in which load-supporting structural members are wrecked or taken out are demolitions.
    "Regulated asbestos containing material" or "RACM" means (a) Friable asbestos material, (b) Category I nonfriable ACM that has become friable, (c) Category I nonfriable ACM that will be or has been subjected to sanding, grinding, cutting, or abrading, or (d) Category II nonfriable ACM that has a high probability of becoming or has become crumbled, pulverized, or reduced to powder by the forces expected to act on the material in the course of demolition or renovation operations regulated by 40 CFR 61, Subpart M.

    If these activities are involved, see PDEQ Asbestos webpage or contact PDEQ at (520) 724-7400 for permitting and notification requirements.
