Releases of Crude Oil

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

No Information Given
Cause: COLD WEATHER. Broken line, possibly due to recent freeze but still under investigation, no info given as to where line is located.

Followup: No

Notes: BRQ. LDEQ reports states that based on analytical results, no reportable quantities were exceeded. Took sample of spilled material for analysis. No info given as to actual time duration of leak, only discovery time and time secured. LDEQ and State Police reports only. No refinery letter required - courtesy notification.
10.0 gallons

oily water sewer junction box
Cause: The release occurred eastern perimeter of the Unit 222 Saturates Gas Unit. Discharge discovered during an inspection of the stormwater sewer system. Excavation in the area determined the source of oil to be a leaking oily water sewer (OWS) junction box.

Followup: No

Notes: The leaking OWS junction box was isolated on July 31, 2012. Excavation activities to remove contaminated soil into 55-gallon drums and roll-off boxes were ongoing during time of the report. The excavated material was to be tested and properly disposed of at a permitted facility. Marathon claimed that they would collect soil samples under completion of the removal of contaminated soil and those samples would be analyzed to verify that the soil meets the allowable levels set forth in LDEQs Risk Evaluation/Corrective Action Program (RECAP) document. Any subsequent recommendations were to be implemented to prevent reoccurrence of the incident upon completion of the investigation. LABB was unable to find the LDEQ verbal report or original SPOC report. They claimed the release was less than 10 barrels so we estimated the release to be 9 barrels, which is 378 gallons.

North Ground Flare
Flange on the Pitch Exchanger 210-1317-08
Cause: The 210-1513-01 Vacuum Bottoms Pump inboard and outboard motor bearing housings were smoking during routine observations. The 210-1513-02 Vacuum Bottoms Pump (back-up) was already out of service for repairs. The board operator was notified and started reducing Crude charge rate. The 210-1513-01 Vacuum Bottoms pump was shut down due to the outboard motor bearing igniting. The 210 Crude Unit shutdown procedure was initiated. The 210-1801-01 Offgas Compressor tripped due to a high level in the 210-1202 Compressor Suction Drum. Both pumps were already on in automatic. The outsider operator opened the bypass around the flow controller to the Product Receiver. Crude overhead gas was flared in the North Ground Flare. About 5 gallons of crude oil from a flange on the Refinery's Oily Water Sewer and processed in the WWTP.

Followup: No

Notes: The boardman cut charge rates to Crude Unit 10 and shut down Crude Unit 210. Both Compressor Suction Drum pumps were turned on, and the bypass around the flow controller was opened. The operator increased the suction drum pressure to assist the pumps in pressuring out the level to the startup compressor. The incident investigation will result in recommendation items designed to prevent the recurrence of this event. Initial report states material did go offsite. Verbal report and Hazardous Materials Incident Reporting Form state that H2S was released (and incorrectly reporting that the reportable quantity for it is 500 lbs), while the refinery statement letter reports only SO2.
5.0 gallons

Unit 63 Tank Farm
Cause: The product inside the Unit 210 Crude Charge Pump caught fire due to a seal failure. While extinguishing the fire with fire water, some product spilled to the concrete containment around the tank. An incident investigation is being conducted to determine the root cause of the incident. 6-10 bbl of crude oil burned in the tank in addition to one bbl of oil released.

Followup: No

Notes: The pump suction and discharge were blocked in to stop the flow. The Shift Emergency Response Team (SERT) responded and extinguished the fire. A vacuum truck removed the spilled product. The oil was to be reprocessed, and the water would be treated in the waste water treatment plant. The incident investigation will result in recommendation items to prevent the recurrence of this event. There was no medical attention necessary for the exposed individuals.
42.0 gallons
No LDEQ Reported


Cause: Crude oil seeped through the deck plugs of the pump containment of Bouchard Transportation barge B235 which filled the pump containment area spilling approximately 1/2 gallon of product into the Mississippi River.

Followup: No

Notes: Product was contained on the barge and boom was deployed in the Mississippi River.
0.5 gallons

Seal on Crude Tank 500-1
Cause: The leak occurred on Storage Tank 500-1, however the leaking component was an agitator which is permitted with Tank Farm- Unit 63 Fugitives. The Unit 63 Fugitives EIQ number is Unit 63 Fug (EQT No. FUG 084). Approximately 9.05 barrels (2568 pounds) of crude oil was released onto the ground within the tank dike. Also Human Performance Difficulty (procedures not used and training needs improvement), Product Control did not turn off mixer when spotted the leak.

Followup: Yes

Notes: The shift supervisor dispatched a vacuum truck to the site to recover the oil that had leaked onto the ground. In addition, a large catch basin was placed under the leaking mixer seal so the crude oil could be collected as it was leaking while the tank was being emptied. Recommendations: - Provide training on the message responses and operating procedures. - Develop a Lessons Learned to address Process Safety recognition failure. Evaluate changing the 12 feet message to and actual alarm on 63-LI-5001.
