|LDEQ Accident Number
|Point Source(s)||Notes||Amount of Release|
|491-X-9E/F||Cause: A leak developed on the channel head of the heat exchanger while it was being taken out of service for maintenance. |
Notes: An operator was working nearby when the leak occurred. The operator went through HF decontamination on the unit and then complained of eye discomfort. The operator was initailly treated onsite the transferred to West Jeff hospital.
|Hydrofluoric Acid: 20.0 pounds|
|Diesel Hydrotreater Unit||Cause: A small fire occurred in the convection section of the Diesel Hydrotreater Unit 293 in one of the tubes. While in the process of isolating the H-1 Heater for inspection and repair of the tube, the tube completely failed resulting in a fire in the entire convection sectino of the heater.|
Notes: The Refinery's Fire Brigade and Emergency Response Teams were activated and the fire was extinguished. No offsite impacts were noted during air monitoring.
|Sulfur Dioxide: 240.8 pounds|
Hydrogen Sulfide: 2.4 pounds
|No Information Given||Cause: Spill of kerosene from a leaking pipe.|
Notes: The kerosene fell onto paved area that drains to the WWTP. No product left facility property.
|Kerosene: 84.0 gallons|
|292-FF, 308F-D-1 Low Pressure Flare||Cause: Vapor leak coming from a tube at the exchanger. Unit 292 was depressurized and shut down which caused flaring.|
Notes: Determined that preventative maintenance procedures could not prevent this accident.
|Sulfur Dioxide: 673.0 pounds|
Hydrocarbon: 399.0 pounds
Hydrogen Sulfide: 90.0 pounds
Nitrogen Oxide: 5.0 pounds
|Pressure Safety Valve (PSV)-850 on sphere 100-T-500||Cause: Cracked pipe leading to Pressure Safety valve|
Notes: Cracked pipe replaced. Exceeded hourly permit for VOC emissions. Air monitoring performed by refinery personnel near leak and the nearest fenceline. No impact found by refinery personel. Emissions below reportable quanitity.
|Butane: 205.0 pounds|
|No Information Given||Cause: Lebeouf Bros. Towing, LLC. was transferring oil from the Conoco Refinery to the Gonsulin 104 Oil Barge and a leak developed in a transfer line which resulted in approximately 1 barrel of product being released onto the barge.
*Report filed by ES&H Consulting Group (contracted by LeBouf Bros. Towing, LLC).
** This incident is NOT listed on the master list.|
Notes: Upon discovery of the leak, the transfer operation was immediately terminated. All released product was contained on the oil barge. In site personnel initiated cleanup with absorbents, and an ES&H OSRO crew was dispatched to assist. After further investigation, the released quantity was determined to be 10 gallons. A large amount of rain water was present on the deck which was initially mistaken for product. No offsite impact reported.
|Crude Oil: 76.9 pounds|
|Alkylation Unit Isobutane recycle line||Cause: LDEQ report states, "Isobutane leak. There is a pinhole leak in the alkyl unit. The leak could only be seen after temperatures dropped and condensate was visible."
Incident report states, "preliminary inspection found that the leak had occurred in a weld on the recycle line. Because the weld failure mechanism is unknown and would require further metallurgical testing."|
Notes: Incident report states, "it was decided that the entire Isobutane recycle line shall be replaced with new pipe before starting up the Alkylation Unit."
|Volatile Organic Compounds (VOCs): 314.8 pounds|
Hydrogen Flouride: 3.2 pounds
|Butane Divert Line||Cause: A pinhole leak was discovered on the 6 inch elbow of the Alkylation Unit's butane divert line.|
Notes: BRQ. A water spray was applied to the leak. Nitrogen was routed into the out of service station of piping to clear the process hydrocarbon out of the leaking section of piping and prevent any further process hydrocarbons from leaking out. A clamp was installed afterwards, once nitrogen became the only chemical being released from the leak. Air monitoring was performed throughout the event, and the clamp was monitored to ensure that nothing was leaking.
|Volatile Organic Compounds (VOCs): 580.0 pounds|
