What does the term 'Native Soil' refer to in the context of underground storage tanks?

The term 'Native Soil' refers to the soil that exists in its natural state at a given location, particularly in the context of underground storage tanks. It encompasses the soil outside the immediate boundaries of an excavated pit for a tank, as this soil has not been disturbed or altered from its original condition.

Understanding this term is critical for addressing environmental concerns associated with underground storage tanks, as it helps in assessing potential contamination and the need for remediation efforts. When a tank is installed or removed, attention must be paid to the characteristics of the native soil to ensure that any contaminants do not spread beyond the immediate area.

In this context, native soil is distinct from other types of soil, such as soil that has been treated for contamination, which would not retain its original properties, or soil that is specifically designated for agricultural use, which involves modifications and treatments for farming purposes. Recognizing the definition of native soil is essential for anyone working with underground storage tanks and dealing with potential environmental impacts.
