Which of the following statements about UST systems is true?

  1. All UST systems are above ground

  2. UST systems must be monitored for leaks

  3. UST systems have no regulations

  4. UST systems are not used for petroleum products

The correct answer is: UST systems must be monitored for leaks

UST systems, or Underground Storage Tank systems, are required to be monitored for leaks as part of their compliance with environmental regulations. This monitoring is crucial because leaks can lead to contamination of soil and groundwater, posing significant environmental and public health risks. The U.S. Environmental Protection Agency (EPA) and various state regulations mandate that UST systems implement leak detection methods to ensure that any potential leaks are identified and addressed promptly. This monitoring can involve various technologies, such as automatic tank gauging, vapor monitoring, or secondary containment systems, all designed to detect the presence of leaks early and mitigate their impact. Understanding this requirement highlights the importance of safety and environmental stewardship in managing UST systems, ensuring that operators are vigilant and proactive in preventing contamination. The other statements do not align with the regulatory framework governing UST systems, which include strict monitoring and operational practices to safeguard against leaks and environmental damage.
