Which of the following is NOT a responsibility of a Class C operator?

A Class C operator's primary responsibilities revolve around day-to-day operations and making sure the tank system is being monitored effectively to prevent and respond to spills or leaks. Monitoring for leaks is an essential duty, as is responding to alarms, which helps ensure that any issues are dealt with promptly to maintain safety and environmental integrity. Understanding the size and type of the underground storage tank (UST) is also necessary for proper operational procedures.

Reconnecting breakaway valves, however, falls under the realm of more technical responsibilities, which typically would be handled by Class A or B operators or licensed technicians. Class C operators are not expected to perform technical repairs or adjustments that would require in-depth knowledge of the system’s mechanics, making this task outside their designated responsibilities. Thus, correctly identifying this task illustrates an understanding of the role distinctions within UST operations.
