Oklahoma UST Operator Training | Class A/B & C

UST training in Oklahoma is required by federal law and is intended to ensure that those who own and operate underground storage tanks understand how to operate and maintain UST systems properly.

As required by the EPA, all UST operators must be trained by October 13, 2018. After this date, new Class A and B operators must be trained within 30 days of assuming duties. Class C operators must be trained before assuming duties. This applies to the entire state of Oklahoma as well as other states.

In 2015, the EPA revised the UST regulations which includes minimum training requirements for owners and operators of UST systems. Training is required per operator class:

  • Class A training is required for person(s) having primary responsibility for on-site operation and maintenance of UST systems (owner or operator of a UST facility).
  • Class B training is required for persons involved with daily on-site operation and maintenance of UST systems.
  • Class C training is required for daily on-site employees having primary responsibility for addressing emergencies presented by a spill or release from a UST system.

Oklahoma UST Class A/B Operator Training

Oklahoma Class A operators have primary responsibility for on-site operation and maintenance of a UST facility. This individual is generally the owner of the station or the designee. For large corporations, this person is the manager or designee responsible for tank operations.

Oklahoma Class B operators have responsibility for the day-to-day aspects of operating, maintaining, and record keeping of a UST facility. This individual (or individuals) is generally the owner or the person/company contracted by the owner to maintain the tanks. For large corporations, this person is the employee, or person/company contracted by the corporation to maintain the tanks.


The UST Class A/B operator training course is presented in chapters. Each chapter utilizes multimedia to enrich the learning experience. Each chapter is followed by a quiz. If the student answers a quiz question incorrectly, the quiz feedback redirects the student to the correct course information.

In addition to the quizzes, the UST Class A/B operator training course includes a final exam of 100 questions, 80% of which must be answered correctly in order to print a certificate.

There is not any time restriction to access the course, so students can complete the entire course in a single session (approximately 4 hours plus exam time) or take the course in segments.

Duration: 4 hours

Purpose & Objective

The purpose of the Underground Storage Tank (UST) Training Program is to protect human health and the environment by preventing future petroleum underground storage tank releases and remediating existing petroleum underground storage tank contamination.

Class A operators must be trained how to manage resources and personnel; maintain compliance with federal, state, and local regulations; ensure that required records are kept; and that operators at the facility are trained to respond to releases, spills, and other emergencies.

Class B operators must be trained how to meet recordkeeping and reporting requirements; ensure that equipment complies with industry standards; and train personnel to properly respond to emergencies caused by releases or spills.

By combining Class A and Class B operator training into a single test, important employee cross-training is achieved.

Oklahoma UST Class C Operator Training

Oklahoma Class C Operators are the first responders to emergency situations at a UST facility – like a gas station or convenience store. These individuals are usually the clerks of a facility.

Class C Operators monitor fuel deliveries to the tanks; control and/or monitor the dispensing or sale of regulated substances; and respond to alarms, releases, and other emergency situations.

Course Description

The UST Class C operator training course consists of seven chapters. Each chapter is followed by a short quiz. Once a student has completed all chapters and quizzes, the learner will be directed to print out a course checklist.

The course is instructed through a student orientation tour of a mock facility, where a manager (or Class B Operator) will identify and explain each topic and then mark them off a checklist when completed. When the checklist has been completed, the student can then print the UST Class C operator certificate.

There is not any time restriction to access the course, so students may take as much time as needed to complete their training.

Duration: 1 hour

Purpose & Objective

The purpose of the Underground Storage Tank (UST) Training Program is to protect human health and the environment by preventing future petroleum underground storage tank releases and remediating existing petroleum underground storage tank contamination.

Class C operators must be trained how to respond to emergencies (such as situations posing an immediate danger or threat to the public or to the environment and that require immediate action) and alarms caused by spills or releases from an underground storage tank system.

Oklahoma UST State Agency & Regulations

The Oklahoma Corporation Commission (OOC) – Petroleum Storage Tank Division (PSTD) has been designated to protect public health and the environment through oversight, investigation and cleanup of soil and groundwater contamination caused by releases from USTs. The Division enforces state and federal regulations which pertain to the storage, quality, and delivery of refined petroleum products (i.e., gasoline and other fuels).

UST Training in Oklahoma
The Oklahoma Corporation Commission (OCC) regulations on underground storage tanks (Title 165 – Chapter 25) requires that each facility was to have certified UST Class A and B and Class C operators by July 1, 2011.

165:25-1-120. Training requirements.
Each underground storage tank system or group of underground storage tank systems at a facility must have a Class A, Class B, and Class C operator designated. Separate individuals may be designated for each class of operator or an individual may be designated to more than one of the operator classes.

165:25-1-122. Operator Class designations.

  • (a) A Class A operator has primary responsibility to operate and maintain the underground storage tank system in the broader aspects of the statutory and regulatory requirements to achieve and maintain compliance.
  • (b) A Class B operator implements applicable requirements and standards for one or more facilities to monitor day-to-day aspects of operation and recordkeeping.
  • (c) A Class C operator is an onsite employee responsible for responding to alarms or emergencies caused by spills or release from underground storage tank systems.

All Operators must post “Oklahoma Operator Certificate(s)” along with the Oklahoma Corporation Commission (OCC) Fuel Permit.  After the Class A/B Operator completes the Operator Training Program, the system will prompt the trainee to print a certificate.  The certificate must be posted at the facility.  A Class C Operator must receive site specific training from a certified Class A or B Operator.  The “Certificate of Training for Class C Operators” must list those eligible and it must be posted at the facility.

Oklahoma was granted state program approval (SPA) in 1996.

Retraining Requirements
165:25-1-124. Frequency and proof of training.
Class A and Class B operators must be re-certified every 3 years. In addition, if the Oklahoma Petroleum Storage Tank Division (PSTD) determines an underground storage tank system is out of compliance, the class A or class B operator, or both, must be retrained. As a result of the retraining of Class A operators or Class B operators, subsequent re-training of the Class C operators shall also occur. Voluntary refresher training is encouraged to ensure operator is up-to-date with current regulations and procedures.
