ABCs of UST operator training
“Operator error” isn’t something anyone likes to see, especially when it applies to leaks from underground tanks of petroleum or hazardous materials. That’s why it’s essential to train individuals to manage underground storage tanks (USTs) correctly. Training obligations vary for each type of UST operator. Federal regulations establish three categories:
- Class A operators,
- Class B operators, and
- Class C operators.
Properly trained operators are vital to managing USTs safely and in compliance. Use this guide to understand the different training requirements for Class A, B, and C operators.
An overview of roles
The Environmental Protection Agency (EPA) requires all owners and operators of UST systems to designate:
- One Class A operator and one Class B operator for each UST or groups of USTs, and
- Each qualifying person at the facility as a Class C operator.
Class A operators are responsible for operating and maintaining USTs in line with the regulations. A Class A operator generally manages the resources and personnel involved to ensure UST operations comply.
A successfully trained Class A operator:
- Makes informed decisions about compliance; and
- Determines whether the facility complies with operation, maintenance, and recordkeeping requirements.
Class B operators handle the day-to-day responsibilities for managing USTs (like conducting in-field operations).
A Class B operator with sufficient training implements applicable regulatory requirements in the field on typical UST system components or site-specific equipment.
Class C operators provide immediate responses to UST-related problems.
An adequately trained Class C operator takes the necessary response actions to emergencies or alarms caused by UST spills and releases.
Basic training requirements
EPA outlines the minimum training requirements for each operator type at 40 CFR Part 280 Subpart J. All classes of operators must be trained or pass a comparable examination. Class C operators have the additional option to receive training from a Class A or B operator at the facility.
A facility can designate an individual for multiple operator classes. Any person with multiple designations must complete the required training or comparable examination for all applicable classes.
Class A and Class B operators must be trained within 30 days of beginning UST duties. Class C operators have to be trained before starting their UST responsibilities.
Class A operators should understand the purpose, methods, and functions of:
- Spill and overfill prevention;
- Release detection;
- Corrosion protection;
- Emergency response;
- Product and equipment compatibility and demonstration;
- Financial responsibility;
- Notification and storage tank registration;
- Temporary and permanent closure;
- Related reporting, recordkeeping, testing, and inspections;
- Environmental and regulatory consequences of releases; and
- Training requirements for Class B and Class C operators.
Class B operators may be trained in either:
- General requirements for all compliance rules and the equipment commonly used at UST facilities, or
- Site-specific requirements that only cover the regulations and equipment applicable to the facility.
Additionally, Class B operators need to know the purpose, methods, and functions of:
- Operation and maintenance;
- Spill and overfill prevention;
- Release detection and related reporting;
- Corrosion protection;
- Emergency response;
- Product and equipment compatibility and demonstration;
- Reporting, recordkeeping, testing, and inspections;
- Environmental and regulatory consequences of releases; and
- Training requirements for Class C operators.
Class C operators must know how to respond with the correct actions to emergencies or alarms that are caused by spills or releases from UST operations, including notifying the authorities.
Common training questions
Consider these FAQs to help ensure your UST operator training programs comply.
How are operators evaluated?
Facilities must evaluate each operator via testing, a practical demonstration, or another approved approach.
When is retraining required?
If a UST system is found to be noncompliant, Class A and Class B operators at the facility must complete a training program or comparable examination that at least covers the areas out of compliance (unless exempt per 280.244).
Retraining should be completed within 30 days of the noncompliance determination. The training program or examination has to be developed or administered by a third party (i.e., an independent organization, the implementing agency, or a recognized authority).
How is training tracked?
Facilities are required to keep paper or electronic records that verify training and retraining for as long as the operators are designated. The records should contain at a minimum the information at 280.245(b).
What about state requirements?
It’s essential to check state UST regulations where your facilities operate. EPA has approved most states to implement the UST program. State requirements are at least as stringent as federal standards, and many state programs impose stricter rules.
Usually, operator training is obtained from third-party organizations that must be registered and approved by state environmental agencies to ensure the programs comply with federal and state requirements.
Key to remember: Training requirements for underground storage tank operators are based on their designated class: A, B, or C.
