What should happen to exterior above-grade fill piping when tanks are abandoned or removed?

When tanks are abandoned or removed, it is crucial for exterior above-grade fill piping to be removed. This is because leaving the piping in place can pose safety hazards, such as the potential for leaks that could lead to contamination of the environment or groundwater. Piping associated with abandoned tanks may also create confusion or complications if future installations or inspections occur.

Removing the fill piping eliminates any risks associated with unused infrastructure, ensuring that there are no lingering connections to potentially hazardous materials. This practice aligns with safety regulations and standards set forth to maintain a safe environment and prevent future liabilities. While sealing, inspecting, or painting might seem like potential options for handling abandoned infrastructure, they do not adequately address the underlying risks associated with leaving the fill piping in place. Therefore, the correct response emphasizes the importance of completely removing such piping once the tanks are no longer in use.
