How many classes of operators must be trained in UST management?

The correct answer indicates that there are three classes of operators that require training in Underground Storage Tank (UST) management. These classes are categorized based on the level of responsibility and involvement with USTs.

Class A operators are responsible for the overall operation and maintenance of UST systems. They focus on compliance with regulatory requirements and are involved in management decisions related to USTs. Hence, their training includes a comprehensive understanding of federal and state regulations, financial responsibility, and environmental impacts.

Class B operators manage the daily operations of USTs, which includes tasks such as monitoring tank levels and maintaining equipment. Their training ensures they have the necessary skills to respond to emergencies, perform inspections, and execute preventive maintenance effectively.

Class C operators are typically the personnel who handle immediate response to alarms or customer inquiries at the facility. Their training focuses on recognizing and responding to hazardous material spills and other emergencies that may arise in relation to USTs.

Having these three classes of operators trained ensures comprehensive coverage of UST management practices, which is crucial for compliance with regulatory standards and for safeguarding both the environment and public health. This training structure reflects a robust approach to managing UST systems effectively.
