What should be done with a UST that is no longer in use?

Properly closing and decommissioning a UST that is no longer in use is essential for several reasons. First, decommissioning prevents potential environmental contamination that could arise from fuel leaks or releases from the tank. By following the correct closure procedures, operators can ensure that any residual hazardous materials are safely managed and removed.

Additionally, many regulatory agencies have strict guidelines that outline how a UST must be closed to protect public health and the environment. This process typically involves cleaning the tank, removing any remnants of product, and filling the tank with an inert material or safely dismantling it, depending on local regulations.

This approach also minimizes liability for the operator and helps maintain compliance with environmental laws, which can be crucial for future site development or inspections. In contrast, leaving a tank in place or improperly disposing of it can lead to significant regulatory penalties and environmental damage, making proper closure not only a best practice but also a legal requirement in many jurisdictions.
