The revised standard is now known as "Standard for the Inspection of Aboveground Storage Tanks." It incorporates key changes such as: A risk-based inspection schedule. Tanks with a means of detecting a release of product are inspected less frequently.

A system must be capable of diverting leaked product and/or incorporating a release-prevention barrier while providing for prompt detection through periodic inspection by the owner. Single-wall tanks sitting directly on soil pose the greatest risk for an incident and therefore require more frequent inspections.

Inspection of field-erected tanks up to a maximum 30 foot (9.14m) diameter and a maximum shell height of 50 feet (15.24m) - which would equate to a capacity of about 265,000 gallons (1,002,840 litres). This will allow one inspector to inspect virtually all tanks at a facility where both field-erected and shopfabricated tanks are installed.

Other significant changes include sections on safety considerations, inspection of portable containers (55 gallons or more), suitability-forcontinued- service guidance, and expanded periodic inspection checklists.
