What is required if there are no visible signs of contamination during decommissioning?

When decommissioning a heating oil tank, the procedures involve ensuring that the site is free from potential contamination. If no visible signs of contamination are observed, it may be tempting to conclude that no further action is necessary. However, adhering to standard sampling protocols is crucial. This is because contamination can be present even if it isn't visually apparent.

Standard sampling protocols typically involve taking soil samples at various depths and locations around the tank to detect any hidden contaminants that may have leached into the soil. This comprehensive approach helps ensure that any potential risks to human health and the environment are adequately addressed, complying with regulatory requirements and best practices for environmental protection.

In summary, following standard sampling protocols, even when there are no visible signs of contamination, provides a more thorough assessment and reinforces the integrity of the decommissioning process. This is essential for successful compliance and environmental safety.
