Training Overview

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.

To successfully register for a dust control certification course, all participants 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.

Customers can also purchase and prepay for multiple 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.

Important Notes:

  • If you purchase a single dust control class of any type (even if you are purchasing other courses as well), it will automatically assign the class to the account that purchased it.  For additional assistance on how to register for a dust control training course, please review the Learning Cart Registration Instructions.
  • You have two attempts to complete the test at the end of the course. If you fail the course both times, you will need to purchase and retake the appropriate class again.
