Inspection Guidance:

This checklist is intended as a model. Locally developed checklists are acceptable as long as they are substantially equivalent (as applicable). Inspections of multiple tanks may be captured on one form as long as the tanks are substantially the same.

For equipment not included in this Standard, follow the manufacturer recommended inspection/testing schedules and procedures.

The periodic AST Inspection is intended for monitoring the external AST condition and its containment structure. This visual inspection does not require a Certified

Inspector. It shall be performed by an owner’s inspector per paragraph 4.1.2 of the standard.

Upon discovery of water in the primary tank, secondary containment area, interstice, or spill container, remove promptly or take other corrective action. Inspect the liquid for regulated products or other contaminants and dispose of properly.

Non-conforming items important to tank or containment integrity require evaluation by an engineer experienced in AST design, a Certified Inspector, or a tank manufacturer who will determine the corrective action. Note the non-conformance and corresponding corrective action in the comment section.

Retain the completed checklists for at least 36 months.

After severe weather (snow, ice, wind storms) or maintenance (such as coating) that could affect the operation of critical components (normal and emergency vents, valves), an inspection of these components is required as soon as the equipment is safely accessible after the event.

This checklist is intended as a model. Locally developed checklists are acceptable as long as they are substantially equivalent (as applicable).

For equipment not included in this Standard, follow the manufacturer recommended inspection/testing schedules and procedures.

The periodic AST Inspection is intended for monitoring the external AST condition and its containment structure. This visual inspection does not require a Certified

Inspector. It shall be performed by an owner’s inspector per paragraph 4.1.2 of the standard.

Remove promptly standing water or liquid discovered in the primary tank, secondary containment area, interstice, or spill container. Before discharge to the environment, inspect the liquid for regulated products or other contaminants and disposed of it properly.

In order to comply with EPA SPCC (Spill Prevention, Control and Countermeasure) rules, a facility should regularly test liquid level sensing devices to ensure proper operation (40 CFR 112.8(c)(8)(v)).

Non-conforming items important to tank or containment integrity require evaluation by an engineer experienced in AST design, a Certified Inspector, or a tank manufacturer who will determine the corrective action. Note the non-conformance and corresponding corrective action in the comment section.

Retain the completed checklists for at least 36 months.

Complete this checklist on an annual basis, supplemental to the owner monthly-performed inspection checklists.

Note: If a change has occurred to the tank system or containment that may affect the SPCC plan, the condition should be evaluated against the current plan requirement by a Professional Engineer knowledgeable in SPCC development and implementation.
