Basic Underground Storage Tank (UST) Info

In 1985, EPA created the Office of Underground Storage Tanks to carry out a Congressional mandate to develop and implement a regulatory program for underground storage tank (UST) systems. EPA works with its state, territorial, and tribal partners to prevent and clean up releases from UST systems. For the legislative history of the UST program, see “What Is The History Of The Federal Underground Storage Tank Program?

What Is An Underground Storage Tank System?
An underground storage tank system is a tank and any underground piping connected to the tank that has at least 10 percent of its combined volume underground. The federal UST regulations apply to only underground tanks and piping storing either petroleum or certain hazardous substances.

Who Implements The UST Program?
The underground storage tank program is primarily implemented by states and territories. Your first point of contact is the state or territorial regulatory agency that has jurisdiction where the USTs are physically located. See state and territorial UST program offices for a list of contacts.

If you have a question that involves USTs in Indian Country, contact your EPA regional office. EPA has responsibility for, and authority over, USTs in Indian Country.

How Do Underground Storage Tanks Affect Groundwater?
Leaking underground storage tank systems pose a significant threat to groundwater quality in the United States. It has been reported that groundwater supplies drinking water to approximately 50 percent of the nation’s overall population and 99 percent of the population in rural areas. The following resources provide information about underground storage tanks and groundwater.

EPA Minimum Training Requirements

UST Training - EPA The EPA established the following minimum training requirements for designated UST Class A, Class B, and Class C operators. All 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.

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

  • 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
  • Training requirements for Class B and Class C operators

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 B operators – Each designated Class B operator 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:

  • 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
  • Training requirements for Class C operators

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.

The Training Program

Training Requirments – 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.

Retraining – 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:

  • Class A and B operators take annual refresher training.
  • The implementing agency waives retraining.

Records – 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.
