UST Operator Training

ADEQ provides no-cost underground storage tank (UST) systems Class A/B training through Petroclassroom to help owners and operators meet requirements and ensure UST systems are properly managed to minimize health and safety issues and protect the environment. 

Pre-registration for Petroclassroom is required. Register in advance at www.petroclassroom.com. There is high demand for this training and space is limited, so wait lists are common. If you are registered and unable to attend, please notify Petroclassroom at 844-303-6752 or info@petroclassroom.com to cancel your registration 5 business days before the class date. This allows Petroclassroom enough time to contact a waitlist individual to take your place. Walk-ins are welcome, however, on-site registration may not be available due to the size of the class.

What are Class A, B and C operators?

The owner or operator of an underground storage tank (UST) system must designate a Class A, B, and one or more Class C individuals to complete operator training.

  • Class A Operators have the primary responsibility of assuring the regulated facility(s) meet compliance and documentation requirements set by law. Each designated Class A operator must either be trained or pass a comparable examination that provides general knowledge of USTs.
  • Class B Operators must either be trained or pass an examination about the regulatory requirements and typical equipment used at UST facilities; or site-specific requirements which address only the regulatory requirements and equipment specific to the facility.
  • Class C Operators must either be trained by a Class A or Class B operator; complete a training program; or pass a comparable examination. The training option chosen must teach or evaluate the Class C operator's knowledge to take appropriate actions (including notifying appropriate authorities) in response to emergencies or alarms caused by spills or releases resulting from the operation of the UST system.

Do owners and operators have to be Class A or B?

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 (it’s free!)

How often do I need to renew my A/B Operator Certification?

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.
