How does a site check differ from a site assessment?

A site check is specifically conducted when there is evidence or suspicion that a release of hazardous substances, such as petroleum or other contaminants, has occurred at an underground storage tank site. It serves as an immediate investigation to assess the extent of any potential release, providing a targeted approach to detect contamination and address any immediate risks.

In contrast, a site assessment is a more comprehensive evaluation that aims to determine if a release has occurred and to what extent. This involves a thorough investigation of the site, including reviewing historical data, sampling soil and groundwater, and assessing environmental impacts. A site assessment goes beyond just confirming a release and focuses on understanding the full implications and conditions of the site.

Thus, option B accurately reflects the distinct purposes and approaches of a site check versus a site assessment.
