Maricopa County Air Quality Department Dust Control Training Website
All in-person dust control training classes are temporarily suspended due to COVID-19.
This website provides information about training classes offered by the department and enables you to register for Rule 310 and Rule 316 basic and comprehensive classes being offered online. Online class fees are the same as in-person class fees. You may need dust control training if your work involves dust-generating operations or the processing of concrete, asphalt, or rock products (including crushing or screening rock products).
All dust control certifications are valid for three years from the date of issuance. Dust control classes often fill quickly, so be sure to register well in advance of the expiration of your certification. Newly-hired employees will be granted 30 days from their date of hire to complete training and attain the applicable certification. An identification card will be issued by the department upon completion of the training. This card must be carried by the certified individual at all times while on site.
If you are involved in dust-generating operations (such as construction, earthmoving, or bulk material handling), you are subject to Rule 310 and may need dust control training. If your work involves processing (such as crushing, mechanized screening, or bagging) rock products, asphalt, or concrete, you are subject to Rule 316 and may need dust control training. For additional assistance on how to register for a dust control training course, please review the Learning Cart Registration Instructions.
The information provided below is general guidance about the most common circumstances that require dust control training. For additional information, call the training line at 602-372-1467 or email AQTraining@Maricopa.gov.
Water Truck and Water-Pull Drivers
All water truck and water-pull drivers (including subcontractors) must complete at least Rule 310 or 316 basic dust control training. Drivers on sites subject to Rule 310 can take either the 310 basic or the 316 basic training. Drivers on sites subject to Rule 316 must take the Rule 316 basic training.
Site Superintendents and Other On-Site Representatives (Small Sites)
If a site has more than one acre but less than five acres of disturbed surface area, the permit holder's site superintendent or other on-site representative must complete at least Rule 310 or 316 basic dust control training. Note that any site subject to Rule 316, with a rated or permitted capacity of 25 tons or more per hour, regardless of acreage, is subject to the requirements for large sites (below).
If 310 basic training is required, you may substitute 316 basic training. If you 316 basic training is required, you may not substitute 310 basic training.
Dust Control Coordinators or Technicians (Large Sites)
All sites with five or more acres of disturbed surface area and subject to Rule 310 must have a dust control coordinator on site at all times during dust-generating operations. The dust control coordinator(s) must complete 310 comprehensive training. Comprehensive training for Rule 316 may not be substituted for Rule 310 training. It is recommended, but not required, that dust control coordinators for Rule 310 sites be certified to determine opacity of visible emissions according to EPA Method 9. (See Smoke School for certification options.)

If you are a subcontractor who drives on unpaved haul roads or access roads at a site that requires a dust permit, you must be registered as a subcontractor with the Maricopa County Air Quality Department. (See Subcontractor Registration to register.)
The requirements for dust control training are based on the type of work you do, not on whether you are a subcontractor. If any of the work that you perform as a subcontractor is subject to requirements for dust control training (see descriptions above), then you must complete that training.
All dust control certifications are valid for three years from the date of issue. Dust control classes often fill quickly, so be sure to register well in advance of the expiration of your certification.
