ADEQ invites underground storage tank (UST) owners and operators to attend online, no-cost Class A/B/C training for certification and to help ensure UST systems maintain compliance. The online courses are self-paced, cover Arizona-specific information, and include an exam and certificate of completion. You will just need a computer, high-speed internet, and speakers or headphones | Select a No-Cost Course & Start Training Now >
The owner or operator of an UST system must designate a Class A, B, and one or more Class C individuals to complete operator training | Learn More About Requirements >
Not necessarily, some companies choose to hire a qualified third party to be the designated Class A and/or B. If an owner/operator designate a third party as the Class A or B operator, ADEQ still recommends the owner/operator to take the class.
Class A and B operators must be retrained and recertified every 3 years. If the department finds that a storage tank system is significantly out of compliance, the Class A and Class B operator must be retrained and recertified.
