What factors determine the scope of a UST site assessment?

The scope of a UST site assessment is primarily influenced by the history and condition of the underground storage tank, as well as the presence of nearby sensitive receptors. Understanding the history of the UST, including its operational history and any previous incidents of leaks or spills, is crucial in assessing potential contamination risks. Additionally, the physical condition of the tank, including its age, maintenance, and integrity, plays a significant role in determining the likelihood of environmental impacts.

Sensitive receptors, which may include residential areas, schools, hospitals, or natural resources such as water bodies, can be significantly affected by contamination from USTs. Consequently, the assessment must account for the proximity of these receptors to evaluate the potential risk to human health and the environment. Assessing both the tank’s condition and the surrounding environment helps establish the necessary scope for a thorough investigation, ensuring appropriate measures are implemented to mitigate risks to sensitive areas.

Other factors, while relevant, do not encompass the primary criteria for defining the scope as effectively as the history and condition of the UST along with the identification of sensitive receptors.
