Which of the following is a best practice for UST operation?

Regularly updating inventory control systems is a best practice for underground storage tank (UST) operation because it ensures accurate tracking of the product within the tank, helping to identify discrepancies that might indicate leaks or other issues. This proactive approach allows operators to manage tank contents effectively and helps in maintaining compliance with regulatory requirements.

By keeping inventory control systems updated, operators can monitor product levels and flow rates, which can help in early detection of leaks, thus minimizing potential environmental hazards and costs associated with contamination cleanup. This practice also supports the overall safety and integrity of the UST system, ensuring that operations run smoothly and within the legal framework set forth by environmental regulations.
