What the rule says

Quoted word for word from the Texas Administrative Code, Title 30, as published by the Texas Secretary of State. Read on 10/30/2026.

30 TAC §334.602(a)

(a) Owners or operators shall identify and designate for each underground storage tank (UST) facility including unmanned facilities, at least one named individual for each class of operator - Class A, Class B, and Class C. All individuals designated as a Class A, B, or C operator shall, at a minimum, be trained and certified in accordance with this subchapter. For the purposes of this subchapter, the terms "Class A operator," "Class B operator," "Class C operator," "certified operator, " or "designated operator" are terms specific to the training requirements of this subchapter. The term "operator" used without these descriptors is the same as the term "operator" used in this chapter generally and as specifically defined in §334.2(75) of this title (relating to Definitions).

30 TAC §334.603(b)(1)

(1) Class A and Class B operators. Approved training providers must provide verification to all Class A and Class B operators who have successfully completed training, in the form of a written or printable electronic training certificate stating the classification and the date it was obtained. Owners and operators must ensure that training certificates are maintained at each facility, with copies of initial or new certificates provided to the TCEQ at the time that annual self-certification is required for that facility.

30 TAC §334.603(b)(2)

(2) Class C operators. A designated Class B operator for a given facility must provide the facility owner or operator with signed and dated written verification in the form of a list of all Class C operators who have been trained for that facility, which includes the date of that training. Owners and operators must ensure that a current and correct list of trained Class C operators is maintained at each facility.

30 TAC §334.606

Owners and operators of underground storage tank facilities (except unmanned facilities) must maintain required training certification documentation as described in §334.603(b) of this title (relating to Acceptable Operator Training and Certification Processes) on-site and must provide it upon request to a Texas Commission on Environmental Quality (TCEQ) or TCEQ-authorized investigator. Documentation may be maintained electronically off-site if that facility has the capability of producing a clear printed copy which can be provided to a TCEQ or TCEQ-authorized investigator within 72 hours of the time of the investigation. Owners and operators of unmanned facilities must provide documentation as requested by a TCEQ investigator or TCEQ-authorized investigator.

What proof usually looks like

Your letter sets what to show and by when. Match each item on it to records like these:

• The names of your designated Class A, Class B and Class C operators.
• Training certificates for your Class A and Class B operators, showing the class and the date.
• A signed and dated list of trained Class C operators from your Class B operator.
• These papers kept at the site, or able to be printed within the time the rule gives.

Common mistakes

• No one named for one of the three classes.
• A certificate kept by the employee instead of at the site.
• A Class C list that is old, or not signed and dated.
• A trained person who left, and no one named in their place.
