STI Inspection Results

ASTs

Normal Venting

Emergency Venting

Spill Containers

Overfill Prevention

Overfill Prevention (AWARD WINNING)

Interstice

Secondary Containment

Compliance Issues

Why?

Why?

Ultra-Sonic Thickness Testing

Ideal Installation – Generator Tank

Observation Results

■ 200+ Tanks observed for tank integrity

■ Two* with >75% wall thickness losses– Compared to existing

standards

■ Some with evident corrosion– Interior of double wall– External

FINDINGS

Observation Results

■ Most with regulatory, code compliance, operational issues– Vent heights & vent configuration/operation– No overfill protection/Level detection devices– Not UL 142 standard construction– No spill prevention devices– Improper protection from vehicular impact

■ Consistent with Florida Leak Autopsy Study (FLAS)– Mott-Smith Consulting Group

FINDINGS
