Dust Control Training

Due to COVID-19, all in-person dust control training classes are temporarily suspended. Rule 310 and Rule 316 Basic and Comprehensive classes are now being offered online. To register for a Maricopa County Air Quality Dust Control Training Course, see our training website https://mcaqd.learningcart.com.

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). See our Do You Need Dust Control Training? page for more details.

 All dust control certifications are valid for three years from the date of issuance. Dust classes often fill very 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 training and is to be carried by the certified individual at all times while on site.

Maricopa County Air Quality Department is very excited to announce the launch of a brand-new dust control training website. The new training website is a customer directed learning system that brings together all of the department's dust control certification processes including class registrations, course training programs, and the distribution of dust control certification cards. Please visit mcaqd.learningcart.com.

To successfully register for a dust control certification course on the new training website, customers will be required to create an individual user account linked to their specific email address. After successfully creating a user account, customers can select and purchase the certification course that's applicable to their company's work operations and their specific job responsibilities.

The new Maricopa County Air Quality Dust Control Training Website also provides the opportunity for customers to purchase and prepay for training credits to any of the department dust control certification courses. These are pre-paid single use training credits which can be distributed to company employees or other industry professionals to assist with the registration of the dust control training classes.
