Petroleum Storage Tank Program

The University of Texas at Austin has developed the Underground Storage Tank (UST) Program to comply with the State of Texas regulations 30 TAC Chapter 334. The tanks are exempt from the Spill Prevention Control and Countermeasures (SPCC) rules, since the UST rules supersede.

The program encompasses a variety of requirements, including annual tank registration and self-certification, leak detection monitoring and inspection, and inventory control.

Aboveground Storage Tanks

An aboveground tank (AST) is regulated and requires registration and construction notification (for retail service stations) if it has a capacity of more than 1,100 gallons and contains a petroleum product capable of propelling a motor vehicle (excluding naptha or kerosene type fuel).

More information can be found in the regulatory guidance RG-475n (PDF)


The TCEQ requires that each UST facility must have at least one named individual for each class of training, i.e. A, B and C. One person may hold more than one classification of training.  The Class C operators may be trained by Class B operators. All operators must be re-trained every three years.

  • Class A operator has the primary responsibility of ensuring the proper operation and maintenance of a UST system.
  • Class B operator has the primary responsibility of implementing all applicable requirements of these regulations in the field, including day-to -day aspects of the operation and maintenance of the UST system.
  • Class C operator of a UST system must be trained in both general and facility-specific emergency-response procedures.
