Releases of Light Cycle Oil

LDEQ Accident Number
Accident Date		 Point Source(s) Notes Amount of Release
129514

2011-02-25		Hose on Dock 5
Cause: Hose had leak on back dock at hydrocarbon line on Dock 5.

Followup: No

Notes: Sheen observed on river. Less than one barrel of diesel estimated to have been released to the water. One barrel contained on the dock.		84.0 gallons
No LDEQ Reported

2013-02-06		EMS-321 barge
Cause: While connecting Loading Arm #3 to the EMS-321 barge on Dock 3, less than two gallons of Light Cycle Oil (LCO) spilled into the river and dissipated.

Followup: No

Notes: The remaining material was contained in a drip pan on the barge, approximately one gallon. Absorbent pads and booms were used to capture any remaining oil. No usable material was recovered; recovered wasted will be characterized and disposed of properly.		2.0 gallons
No LDEQ Reported

2013-02-06		Loading Arm No. 3
Cause: On Febraury 6, 2013 at approximately 20:25 while the dock operations contractor connected Loading Arm No. 3 to the EMS-321 barge on Dock 3, less than two gallons of Light Cycle Oil (LCO) spilled into the river. The remaining material was contained in a drip pan on the barge. Prior to initiating the connection, the loading arm had been cleared using pressurized air to another barge. However, a pocket of LCO remained in the arm and discharged while making the connection. The oil spilled to the river and dissipated. The remaining oil on the barge structure was cleaned. Waste from the clean-up will be shipped offsite to a non hazardous waste landfill.

Followup: Yes

Notes: While attaching the loading arm, a drip pan was used to contain any free oil, and we verified that all transfer lines were isolated. Absorbent pads and boom were used to capture any remaining oil. The barge company provided personnel to clean the residual oil on their deck and associated piping. No usable material was recovered. The recovered waste was disposed of properly. The following corrective measures will be implemented to prevent this recurrence: 1. Modify procedures to use alternate systems to strip the loading arms using pumps instead of pressurized air. 2. Develop a scope and cost to investigate a permanent system to strip the loading arm to the LCO transfer line. 3. Modify dock log to note loading arm stripping activities and time of activity. *The attached PDF defines itself as a 60 day written follow-up report. No LDEQ number is listed on the document. LABB could not locate the original 7-day refinery letter. The report lists LA Police incident 13-00567, NRC 1037776, but no LDEQ incident number. 4. Communicate the incident to all dock personnel.		2.0 gallons
