Releases of Compressed Flammable Gas
| LDEQ Accident Number Accident Date |
Point Source(s) | Notes | Amount of Release |
| 84073 2005-11-23 | No. 2 Coker Wet Gas Compressor | Cause: The wet gas compressor shut down due to the axial thrust alarm, resulting in emissions from the No. 1 Flare. Following investigation, refinery personnel believe the Wet Gas Compressor shut down due to a momentary loss of lube oil. Followup: No Notes: In an effort to stop the release, the compressor was restarted, but the alarm remained. Following determination by refinery personnel that maintenance was required on the compressor, K-8101 was taken out of service and sent out for repair. A variance was applied for with the LDEQ to authorize the emissions associated with the compressor maintenance. The variance was approved on November 29, 2005, ending this release. | 10,509.0 pounds |

| 126762 2010-09-29 | no information given | Cause: This file only has a brief refinery report with no specific info. Followup: No Notes: No information given | |
| 131070 2011-05-09 | PGC 2nd Stage Aftercooler | Cause: The PGC 2nd Stage Aftercooler leaked hydrocarbon vapors and compressed flammable gas was released to water. OFFSITE IMPACT: Mississippi River. Followup: No Notes: BRQ. Refinery letter states that release was below reportable quantities. The exchanger was isolated and the path to water was closed. A boom was deployed at the source and downriver. | 1,952.0 pounds |
| 130822 2011-04-26 | Fractionator Overhead Fin Fan | Cause: LDEQ states that a leak was observed in the Fractionator Overhead Fin Fan at the Cat Feed Hydrotreater, releasing compressed flammable gas and hydrogen sulfide. Followup: No Notes: RQ. Unit commenced an orderly and safe shutdown in order to stop the leak and make necessary repairs. | 1,791.0 pounds |
| 128972 2011-02-01 | Isobutane Pump number G9005 | Cause: The seal on the isobutane pump failed. Followup: No Notes: BRQ. LDEQ report states that amount released did not surpass the RQ (5000 lbs) for flammable gas. The pump was isolated and taken out of service and the seal was replaced as corrective action. | 1,514.0 pounds |
| 140083 2012-05-26 | Cause: The facility experienced malfunctions when the high pressure waste gas system was shut down in the Coker unit, releasing sulfur dioxide to the flare. High Pressure Waste Gas System (HPWGS) compressors K402 and K406 were unavailable due to mechanical issues and the Flare Gas Management System was used instead. This usually works but the depropanizer surge drum water boot sprung a leak and heavy material entered the shut down HPWGS. Followup: No Notes: The high pressure waste gas system had been restored by the time of the LDEQ Incident Report. | 1,000.0 pounds | |
| No LDEQ Reported 2012-02-09 | No information given | Cause: There is a courtesy notification regarding a release of Compressed Flammable Gas and a potential release of oil. There is no detail in the Incident report regrading the cause of the release. Followup: No Notes: There is no information given regarding the cause or remedial actions. There is no LDEQ report and no SPOC report attached to the file. | |
| 148825 2013-05-20 | Fuel gas line | Cause: On May 20, at approximately 3:15 PM, a leak was detected from a fuel gas line near the Hydrocracking Unit. A failure analysis conducted on the failed section of the pipe indicated that increased water saturation and chloride content in the stagnant zone of the pipe was the cause of the degradation. Followup: Yes Notes: Immediate remedial action was to barricade the area and water was used to dissipate vapors from the release. The line was isolated and a clamp was installed to mitigate the leak. Onsite monitoring was conducted during the events and all results were zero. No emergency conditions or adverse offsite impacts resulted from this release. | 3,445.0 pounds |
| 147393 2013-03-17 | piping | Cause: Due to a crack on a pipeline compressed gas and hydrogen sulfide were released to the air. According to a letter submitted by Chalmette Refining, this was a courtesy notification. Followup: Notes: | |
| 147210 2013-03-07 | Hydrogen Feed Pipe at the Hydrodesulfurization Unit | Cause: On Thursday, March 7, 2013, at approximately 20:30 hours, a leak was detected from a hydrogen feed pipe at the hydrodesulfurization unit. CRLLC is conducting a failure analysis of the pipe to determine the cause of the failure and prevent recurrence. Onsite monitoring was conducted during the events and all results were zero. Compressed flammable gas were released to the air.
A failure analysis was conducted and indicated stress relieving due to high cycle fatigue was the root cause of the event. Followup: Yes Notes: The unit was depressurized and taken out of service in order to isolate and replace the pipe. CRLLC conducted a failure analysis of the pipe to determine the cause of the failure and prevent recurrence. The failure analysis indicated stress relieving due to high cycle fatigue was the root cause of the event. To prevent future recurrence, all existing supports surrounding the piping were inspected and repaired as needed. An additional support was also added near the failure location. | 1,864.0 pounds |
| 156774 2014-06-13 | Pipe running to tank D-9008 | Cause: Personnel identified a pinhole leak on a pressurized light strait run gasoline pipeline that runs to tank D-9008. CRLLC is conducting an investigation to determine the cause of the leak and measures to prevent recurrence. Followup: Yes Notes: Upon discovery, site personnel immediately began working to depressure the line and isolate the leak. At approximately 1201 the leak on the line was noted to have ceased and a plug was safely inserted at approximately 1210 to isolate the line. CRLLC is conducting an investigation to determine the cause of the leak and measures to prevent recurrence. | 1,807.0 pounds |
| 154310 2014-03-06 | Cause: A release of compressed flammable gas, benzene, and sulfur dioxide occurred on March 6, 2014. No further information about accident is given. Followup: No Notes: Only document provided about accident is one page refinery letter. | ||
| 153612 2014-01-30 | Crude #1 PSV | Cause: On January 30, 2014, at approximately 06:30, Chalmette Refining personnel identified an atmospheric Process Safety Valve (PSV) leaking on the Crude #1 stabilizer tower, resulting in a release of a liquid petroleum gas (LPG) material comprised primarily of propane and butane. Followup: No Notes: The issue was safely resolved at 07:15 am by blocking the inlet to the relief valve. The PSV on the Crude #1 stabilizer tower was sent our for evaluation and it was determined that the internal spring had fractured causing the malfunction. A failure analysis of the PSV is being conducted to determine the cause of the failure and prevent recurrence. 60 day follow up is promised but has not been available to LABB. | 24,340.0 pounds |
