Class A and Class B operators must be trained within ___ days after assuming operation and maintenance duties at the UST facility.

• A. 15
• B. 60
• C. 45
• D. 30

Answer: (D)

Training timelines for Class A and Class B UST operators after assuming operation and maintenance duties. The standard requirement is that initial training be completed within 30 days of taking on those duties. This ensures the operator quickly gains the essential knowledge needed to manage the system properly—covering release detection, corrosion protection, overfill and spill prevention, emergency response, and accurate recordkeeping. A 30‑day window balances practicality with the need for timely compliance; waiting only 15 days can be too tight for scheduling and learning, while 60 days or 45 days leaves a longer period where proper oversight might be lacking. So, 30 days is the appropriate deadline.
