Subchapter VIII - Training for Operators of Underground Storage Tank Systems
Section ATCP 93.820 - Designation of Class A, Class B, and Class C operators

(1) Each new or existing underground storage tank system or group of underground storage tank systems at a facility shall have a Class A operator, a Class B operator, and a Class C operator, as designated by the owner or operator and as accredited in accordance with this subchapter.

Note: This subchapter does not preclude any individual from being designated to more than one of the operator classes, provided the individual complies with the requirements for each designated class.

Note: This subchapter does not preclude any individual from being a designated operator for more than one facility that includes an underground storage tank system.

Note: This subchapter does not preclude an owner or operator from contracting with another party to provide Class A, Class B, and Class C operators.

Note: There may be occasions when a Class A, Class B, or Class C operator will not be present at a facility. For example, operators are frequently not present at unmanned facilities, such as emergency generators at telecommunication towers and card lock/card access facilities. However, these operators are still responsible for operation and maintenance activities or responding to emergencies or alarms and are still subject to the requirements of this subchapter.

(3) If the owner and operator of the tank system are separate persons, either the owner or operator may designate the Class A, Class B, and Class C operators at the facility, but both the owner and the operator are under the same responsibility under this section to ensure that Class A, Class B, and Class C operators are designated.
