What is one immediate action required upon discovery of a leak in a UST system?

Upon discovering a leak in a UST (Underground Storage Tank) system, notifying regulatory authorities is crucial because it ensures compliance with environmental laws and regulations that are established to protect public health and the environment. Regulatory authorities are responsible for overseeing hazardous materials and must be informed promptly to initiate any necessary investigation, enforcement action, or remediation efforts.

When a leak occurs, failure to report it can lead to significant environmental damage, as well as legal repercussions for the facility. Prompt notification allows the authorities to assess the situation, provide guidance, and coordinate a response that may include containment measures and cleanup, ensuring that any contaminants do not spread further.

This action aligns with the principle of immediate reporting that is fundamental in managing hazardous materials and protecting the community, making it the primary responsibility of the operator or facility management.
