Aboveground Tank Annual Inspection Checklist (1)

ABOVEGROUND TANK ANNUAL INSPECTION CHECKLIST Facility: Inspection Date:

Inspector Name: Tanks Inspected (ID #’s):

Inspection Guidance: • The annual aboveground storage tank (AST) inspection is intended for monitoring the external AST condition and its containment structure. This visual inspection shall be performed by the Yard Manager, or other responsible representative designated by the Yard Manager, who is familiar with the site and can identify changes and developing problems. Complete this checklist on an annual basis supplemental to the monthly-performed inspection checklists. Multiple tanks may be included on this checklist—use the comment column to identify to which tanks noted non-conforming conditions apply. Inspect the following at all tanks identified within the SPCC Plan: o AST shell and associated piping, piping, valves, valves, and pumps including including inspection of of coatings. Visually inspect all surfaces of the tank, including the bottom. o Containment structures including examination for holes, holes, washout, and cracking in addition addition to liner liner degradation and tank settling. o Test liquid level sensing devices to ensure proper operation. o Inventory spill kits. A shaded cell designates an item in a non-conformance status and that action is required to address a problem. Retain the completed checklists for 3 years with the SPCC Plan or in the Environmental Records file cabinet. •

ABOVEGROUND TANK ANNUAL INSPECTION CHECKLIST Item

Yes

Status No N/A

Comments

Are there noticeable areas of moisture or mold on insulation? Is the insulation sufficiently protected from water intrusion? Does the tank liquid level sensing device operate as required? Are overfill prevention devices in proper working condition? Are tank grounding lines in good condition? Is electrical wiring for control boxes/lights in good condition? Are spill kits adequately stocked? Has a change occurred to the tank system or ii containment that may affect the SPCC plan? Use the following diagrams to note locations of conditions observed that may require corrective action or continual monitoring:

i Paint Failure – significant peeling, cracking, spalling, blistering, pitting and chipping etc. of the paint or coating on an AST resulting in the exposure of the metal surface and corrosion of the tank shell (STI SP001, July 2006). ii the condition should be evaluated against the current plan requirement by the Environmental Manager or a Professional Engineer knowledgeable in SPCC development and implementation.
