Pinholeleak on diesel fuel line of emergency fire water pump
Cause: An oil sheen was noticed at Dock #2. The source was found to be a pinhole leak in a 3/4" fuel line that developed as a result of corrosion. Besides the sheen, there was no other reported off-site impact. The emission point was a pinhole leak on the diesel fuel line of an emergency fire water pump at Dock #2.

Followup: No

Notes: Boom was deployed to prevent the diesel from floating downriver. An incident investigation was initiated on 10/15/13 and is currently in progress. No follow up has been posted to EDMS database as of 3/12/2014.

Marine Vapor Combustor Hydroseal Pot
Cause: The release occurred when the suction line from the Marine Vapor Combustor Hydroseal Pot disconnected from the hose fitting causing spill of diesel fuel to the ground. Approximately 3.71 barrels of diesel fuel was released onto the ground.

Followup: Yes

Notes: The suction line was reattached and secured by the operator as soon as the spill was discovered. An incident investigation was conducted to determine the cause or causes of the incident. Per the investigation, the root cause was identified as Design/Understanding need Improvement. The following recommendations will be implemented: 1) Coach/Train operators on the requirements of tying down cam lock fittings. 2) Evaluate installing a second hydroseal pump or a larger pump to maintain hydroseal drum level. 3) Train dock operators on header flushing procedure changes to prevent hydrocarbon from accessing the vapor system. 4) Evaluate installing a check valve between the dock drain piping and the separator 5) Coach/Counsel supervisors on the expectations of spill reporting. All of the recommendations are to be completed by July 18, 2013.

valve on diesel line on Dock 1
Cause: 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.

Followup: No

Notes: 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.
No LDEQ Reported
