What is a best practice for decommissioning a UST?

The best practice for decommissioning a UST (Underground Storage Tank) involves properly emptying, cleaning, and filling the tank with inert material. This approach ensures that any residual fuel or hazardous substances are safely removed, minimizing environmental impact and the risk of leaks or contamination in the future.

Cleaning the tank involves removing all remnants of fuel to prevent chemical reactions or hazards from remaining materials. Filling the tank with inert material, such as foam or concrete, prevents the tank from collapsing and eliminates the void space that could potentially collect water or debris, further reducing the risk of contamination.

Other practices, such as leaving the tank filled with fuel or connecting it to a wastewater system, pose significant risks to safety and the environment, and ignoring regulatory notifications can lead to legal repercussions and environmental harm. Therefore, the proper decommissioning method is crucial for regulatory compliance and protecting public health and the environment.
