What constitutes a UST "installation"?

The definition of a UST "installation" refers specifically to the act of placing an underground storage tank into the ground. This process involves several critical steps, including site preparation, excavation, and the secure placement of the tank while ensuring compliance with environmental and safety regulations.

In the context of underground storage tanks, installation is a key phase that lays the groundwork for safe and effective operation. It typically involves adherence to various regulatory standards, including the installation of proper spill prevention, secondary containment systems, and other safety measures designed to prevent leaks and environmental contamination.

Other options, while relevant to the broader context of UST management, do not qualify as "installation." For instance, the removal of a UST pertains to decommissioning rather than installation. Updating a UST's software system relates to maintenance and operation, while inspection procedures are focused on the assessment and monitoring of existing tanks rather than their initial setup. Hence, the act of placing a UST in the ground stands out as the only correct answer regarding what constitutes a UST installation.
