UST Class A/B Operator Training

Title XV, Section B of the Energy Policy Act of 2005 amends Subtitle I of the Solid Waste Disposal Act, the original legislation that created the underground storage tank (UST) program. The UST provisions of the Energy Policy Act focus on preventing releases and direct EPA to help states comply with new UST requirements. 

Section 1524 of the Energy Policy Act of 2005 states that EPA, in coordination with states, must develop training guidelines for three distinct classes of operators who operate and maintain federally regulated underground storage tank systems. States receiving funding under Subtitle I shall develop state-specific training requirements consistent with EPA's guidelines. The state-specific training requirements must:

Operator TrainingMinimum Training Requirements and Options
In 2015, EPA revised the underground storage tank (UST) regulations which includes minimum training requirements for owners and operators of UST systems.

EPA established the following minimum training requirements for designated Class A, Class B, and Class C operators. Operators must be trained by October 13, 2018. After this date, new Class A and Class B operators must be trained within 30 days of assuming duties. Class C operators must be trained before assuming duties.

Each designated Class A operator must either be trained or pass a comparable examination that provides general knowledge of the following requirements:

At a minimum, the training program must evaluate Class A operators to determine if they have the knowledge and skills to make informed decisions regarding compliance and determine whether appropriate individuals are fulfilling the operation, maintenance, and recordkeeping requirements for UST systems. Class A operator is the person who has primary responsibility for facility compliance including assuring employment of properly trained personnel, retaining maintenance and fiduciary documentation as well upholding all environmental health and safety standards.  One (1) Class A operator may serve several facilities. 

Class B Operators 

Each designated Class B operator must either be trained or pass a comparable 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:

At a minimum, the training program must evaluate Class B operators to determine if they have the knowledge and skills to implement applicable UST regulatory requirements on the components of either: typical UST systems or site-specific equipment used at their UST facility.

Class C Operators 

Each designated Class C operator 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.

Training Program

This term covers the minimum requirements listed for the classes of operators described above and includes an evaluation through testing, a practical demonstration, or another approach acceptable to the implementing agency. A comparable examination must, at a minimum, test the knowledge of the Class A, Class B, or Class C operators in accordance with the requirements for each class listed above.


Class A and B operators at UST systems determined to be out of compliance must be retrained within 30 days of the determination of noncompliance. For retraining, the training program or comparable examination must be developed or administered by an independent organization, the implementing agency, or a recognized authority. Retraining must, at a minimum, cover those areas found to be out of compliance. Retraining is not required if:


Owners and operators must maintain a record identifying all currently designated operators at the facility. The record must include the operator name, operator class, date assumed duties, and training or retraining dates. In addition, owners and operators must have records verifying completion of training or retraining. This record must have the trainee name, date trained, operator training class completed, name of training company or examiner, and the training company’s name, address and telephone number.
