Accident Classified As: Below Reportable Quantity (BRQ)

Cause of Problem: Equipment Failure

A valve on a diesel line on Dock 1 began leaking, and product was spraying out of the valve. The operator noticed the leak immediately and blocked in the line. The operator released the pressure from the line and isolated the leak by closing a valve upstream to the leaking valve. The operator walked downstairs and noticed that diesel product was leaking through the dock penetration cover. Material was released into the Mississippi River, but no sheen occurred.

Discharge Preventable - Yes

Notes/Remedial Actions

Once product was seen spraying from the valve, the line was immediately isolated. No boom was deployed into the Mississippi River, as the product dissipated immediately. An incident investigation will be conducted to determine corrective actions.
