What is the limit on the number of UST facilities a Class A or B operator can be designated to?

The correct answer is that there is no limit on the number of UST facilities a Class A or B operator can be designated to, as long as they can fulfill their responsibilities effectively. This reflects the flexibility in management capabilities provided to operators, allowing them to oversee multiple facilities simultaneously if they are equipped to do so.

Class A and B operators are responsible for ensuring that UST systems comply with regulations, conduct necessary training, and manage safety procedures. As long as an operator maintains competent oversight of all assigned facilities and meets regulatory requirements, they can manage more than one facility without restriction.

In contrast, some options suggest limitations, such as a maximum number of facilities or restrictions based on geographic boundaries, which are not in alignment with the regulatory framework governing UST operators. These limitations could hinder the efficient management of UST systems, especially in areas with multiple facilities requiring oversight. Therefore, the allowance for multiple designations underlines the importance of effective operational management rather than imposing unnecessary constraints.
