Releases of Benzene
| LDEQ Accident Number Accident Date |
Point Source(s) | Notes | Amount of Release |
| No LDEQ Reported 2005-05-10 | (308F-D-1) Low Pressure Flare; (308F-D-2) High Pressure Flare; (301-D-3) CO Bypass Stack; (591-D-21X) SRU Incinerator | Cause: Entergy experienced a ground fault and the backup supply failed to switch in a timely manner. Forced most process units to shutdown resulting in flaring and venting of CO. Two pressure valves relieved to the atmosphere. Followup: No Notes: With most of the process units down, there was isufficient feed to keep the SRU tail gas treater online. The tail gas from SRU 591 was routed directly to the SRU incinerator until other refinery process units restarted to provide sufficient feed to support stable TGT operation. There was some smoking form the flares. | 216.0 pounds |
| No LDEQ Reported 2005-02-28 | Saturated Gas plant 7991 -V-1 | Cause: The signal to the 7991-V-1 straight run Debutinizer Bottoms level controller stopped transmitting it's signal from the field of the distributed control system Followup: No information given Notes: After inspection a set of wires appeared to be frayed. They sent a group of employees to fix the frayed wires. | 344.8 pounds |
| 100489 2007-10-24 | 1792-FF | Cause: Compressor trip caused by a high level signal from its suction drum which caused a pressure safety valve release. Followup: Yes Notes: Refinery claims that preventative maintenance could not have prevented this accident. | 56.2 pounds |
| 98459 2007-08-07 | Product Dock 1 | Cause: During loading of gasoline onto the ship moored at the product dock. An odor prompted an investigation that found a leaking vacuum breaker valve on the marine vapor recover system leaking.
LDEQ report states that the vacuum breaker malfunctioned and started leaking vapors. Followup: Yes Notes: Operator immediately shutdown the vessel loading and maintenance replaced the valve. Below reportable quantities. | 1.8 pounds |
| 94074 2007-02-19 | Unit 294 | Cause: The pump shaft bering in the LOw Sulfur Gasoline Unit failed causing significant pump vibrations. The vibrations caused the nuts on the bolts of the suction and discharge of hte pump to back out. A small portion of release vaporized to atmosphere a portion was collected in the wastewater system and a portion condensed into the the ground adjacent to the unit. Followup: No Notes: Water deluge system was activated and motor operated valves were activated to secure the pump. The LSG unit was shut down. | 126.0 gallons |
| No LDEQ Reported 2008-09-24 | 1792-FF | Cause: Valve leak during start up of petro chemical unit THD-1792 after Hurricane Gustav. Followup: No Information Given Notes: 30/70% benzene/toluene mixture leaked. Leak sprayed with water washed to the refinery's waste water treatment plant. No mention of the amount of toulene spilled. Monitoring indicated offsite impact. | 10.0 pounds |
| 122186 2010-03-21 | bleeder line (412-FF) | Cause: LDEQ report states, "a spill of 160 bbls of Benzene to the ground inside the perimeter of the facility. The Benzene was released from an open bleeder line as a result of operator error." Report states that benzene spilled into storm sewer system sump, but that all samples were non-detect for benzene and no permit limits were exceeded. Followup: Yes Notes: RQ: The amount of liquid benzene product released exceeded reportable quantities. The facility states that it took corrective actions as soon as the release was discovered. Improved employee training, procedures and storage tank monitoring capabilities. However, the facility failed to submit a timely, updated notification within 60 days of the initial follow up letter. Because this release was preventable under LAC 33.III.501.C.4, the facility will be referred to the Circuit Rider Review process. Follow-up reports were dated 7/9/10 and 7/21/10. | 5,040.0 gallons |
| 121397 2010-02-09 | benzene line leak (412-FF) | Cause: leak developed at a pipe rack support beam for the benzene dock line during annual pressure test procedure--10 gal/59lbs spilled--reportable quantity exceeded Followup: No Notes: RQ. Two gallons recovered by vacuum truck, eight evaporated, air monitoring at perimeter | 59.0 pounds |
| 136882 2012-02-01 | 1391-FF (1391-PSV-009) | Cause: There was an unexpected increase in the Depantanizer tower's overhead pressure causing PSV-009 to relieve. This was the result of the shutdown of the reboiler due to high burner pressure. Followup: No Notes: The reboiler (1391-H-4) temperature was lowered which lowered the pressure in the Depantanizer Tower allowing 1391-PSV-009 to reseat. There is no LDEQ report and no SPOC report attached to this file. 19,570 pounds released | 5.4 pounds |
