What could be a consequence of not properly closing and decommissioning a UST?

Not properly closing and decommissioning an underground storage tank (UST) can lead to environmental contamination. When a UST is not adequately decommissioned, residual petroleum products or hazardous substances can leak into the surrounding soil and groundwater. This can pose significant risks to public health and the environment, leading to long-term ecological damage and costly clean-up efforts. Regulatory agencies require specific procedures to be followed when decommissioning USTs to prevent such leaks and ensure that any potential contaminants are properly handled.

Proper closure procedures are designed to minimize risks and protect natural resources; therefore, failing to follow these steps can result in legal repercussions and financial liabilities related to environmental cleanup. This underscores the importance of adherence to environmental regulations and best practices in the management of USTs.
