Which statement about UST operator training is true?

• A. UST operator training is voluntary.
• B. UST operator training was discontinued.
• C. UST operator training is mandated since 2005.
• D. UST operator training is required only for large tanks.

Answer: (C)

Regulatory training for UST operators is required to ensure safe operation and proper response to issues. Since 2005, operator training has been mandated so personnel who operate or oversee underground storage tanks must complete approved training. This ensures they understand required operation and maintenance tasks, inspections, leak detection, corrosion protection, release response, and recordkeeping—reducing the risk of spills and groundwater contamination. Training isn’t voluntary, isn’t discontinued, and isn’t limited to large tanks; it generally applies to affected UST systems and their operators.
