What is a primary concern when decommissioning underground storage tanks?

When decommissioning underground storage tanks, the potential for leaks or spills is a primary concern because these incidents can lead to significant environmental contamination. If a tank is not properly decommissioned, any residual contents can escape into the soil or groundwater, causing harm to local ecosystems and public health. Identifying and managing these risks is crucial to ensure compliance with environmental regulations and to protect natural resources.

Moreover, potential leaks or spills may not only affect the immediate surroundings but can spread more extensively, resulting in costly clean-up operations and long-term liability issues for the property owner. Therefore, proper assessment, removal, and monitoring during the decommissioning process are essential to prevent such risks.
