What is the first step in the UST site assessment process?

The first step in the UST site assessment process is conducting a preliminary assessment. This initial phase involves gathering existing information about the site and the UST system, which includes the history of the tank, any previous incidents or leaks, and relevant environmental conditions. By performing a preliminary assessment, assessors can identify potential areas of concern and determine the necessity for further investigation.

This step is crucial because it lays the groundwork for the entire assessment process. It helps in understanding the scope of the assessment, informs decision-making regarding the type of sampling and testing that may be needed, and evaluates the potential risks associated with the UST system. With a solid foundation established from the preliminary assessment, the subsequent steps, such as collecting water samples, reviewing documentation, or preparing risk assessment reports, can be executed more effectively and accurately.
