| 118804 2009-10-17 | flare #2 | Cause: Level indicator in the Light Ends Plant over head had malfunctioned. Causing the #3 Pretreater and Hydrocracker (HCU) 1st Stage Stripper overhead off gas flow to suddenly decrease. This caused the pressure to increase and release emissions through flaring (#2). Followup: No Notes: Lowered drum level and stablizied the HCU and PT 3. Repaired indicator by refilling leg with glycerin. | 1,172.0 pounds |
| 118643 2009-10-09 | Waste Gas Compressor | Cause: Waste Gas Compressor lost high pressure and failed. Sent gas to FLARE #1. Followup: No Notes: RQ not exceeded. Flare gas recovery system prevented excessive flaring. | |
| 117083 2009-08-06 | SRU 1 and 2 | Cause: Sulfur Recovery Unit Train (SRU 2) shutdown due to a steam excursion in the refinery. The steam excursion had caused the SRU 2 to shutdown from low boiler water level. The acid gas loading from SRU 2 was added to SRU 1 which caused the emissions.
A second incidence occurred when the refinery lost its hydrogen supply from Air Products. This caused the shutdown of the refinery hydrotreaters and a significant decrease in refinery acid gas production. SRU 1 shutdown due to the insufficient acid gas leading to a second emission. Followup: Yes Notes: acid gas was routed from SRU 2 to SRU 1. Acid gas flaring was avoided and DGA strippers was contained until SRU 1 was restarted. SRU 1 was run at minimal air flow rates to avoid excess H2S consumption due from insufficient acid gas rates. Caustic addition was maximized in tail gas section to mitigate additional SO2 formation. | 1,136.0 pounds |
| 116434 2009-06-12 | coker #2 coke pit and fire lanes | Cause: Failure of the coker fines lane pump discharge check valve resulting from accumulated coke fines, which allowed oil from the coker cutting water tank to back flow into the fines lane. Once the oil came in contact with the hot coke in the pit, a fire resulted. Followup: Yes Notes: Fire was extinguished with foam. Secondary check valve was installed and a cautionary procedure was developed and implemented. | 3,569.0 pounds |
| 115487 2009-06-08 | hose from waste water tank | Cause: Contractor pulled cap off of hose leading to a wastewater tank causing sludge to be released. Followup: No Notes: RQ not exceeded. Release cleaned up for future disposal. | 267.0 pounds |

| 114985 2009-05-14 | flare | Cause: High differential pressure across gas oil feed filters to Cat Feed Hydrotreater (CFHT) prevented feed from entering the unit. Loss of feed to CFHT combined with malfunctioned level indicator (instrument failure) in hot separator resulted in the total loss of liquid level in the hot separator. This created high pressure vapor from the hot separator that was fed to the fractionator. This result in the overheating and over pressuring of the fractionator and increased gas rates to the fractionator overhead. Followup: Yes Notes: RQ exceeded. CFHT rates reduced to a minimum and stopped using propane to minimize temperature and pressure excursions. Level indicator malfunction ocrrected by replacing the anti-freeze. | 2,138.0 pounds |

| 135438 2011-11-20 | #1 Flare | Cause: The flare gas machines lost its pumping ability. The stages on the #1 flare overpressured and burned the gas into the atmosphere. The cause is under investigation. Followup: No Notes: Chalmette Refining provided a courtesy notification to your office regarding a release of Sulfur Dioxide on November 20, 2011. After further review, there were no RQ exceedances or permit violations as a result of this event. | |
| 135259 2011-11-14 | No. 1 Flare | Cause: On November 14, 2011, the high pressure side waste gas compressors were down for scheduled piping replacement. At approximately 1705 hours, the Flare Gas Management (FGM) system compressors stalled, at which time gas that would have been routed to the FGM contractor, was instead routed to the No 1 Flare. The FGM system would have contained the release; however, the FGM seal water was contaminated with hydrocarbon, which is believed to have been a potential result of the Alky Feed PSV overpressure on November 5, 2011 reported under separate cover. The result was intermittent flaring at the No. 1 Flare through November 15, 2011, at 22:01 hours, consequently resulting in emissions of sulfur dioxide in excess of the reportable quantity of 500 lbs. Followup: No Notes: The seal water on the FGM compressors was changed out. CRLLC is investigating the root cause of the release. Based on the results of the Refinery's investigation, appropriate measures will be taken to minimize the likelihood of a recurrence. | 5,296.0 pounds |
| 135184 2011-11-09 | Flare: Flare No. 1 | Cause: The low pressure side waste gas compressor shutdown due to a fuel control valve failure. This routed the low pressure side waste gas to the Flare Gas Management (FGM) system. Followup: No Notes: The fuel control valve was repaired. The low pressure side waste gas compressor was restarted, and the stream was removed from the FGM system. The seal water on the FGM compressors was changed out. There is no SPOC report and no LDEQ report in the file. | 5,484.0 pounds |
| 135138 2011-11-05 | No information given | Cause: No information given. Followup: No Notes: Chalmette Refining provided a courtesy notification to the LDEQ regarding a release of Sulfur Dioxide on November 5, 2011. After further review, there were no RQ exceedances or permit violations as a result of this event. The release did not cause an Emergency Condition or require Offsite Protective Action. | |
| 134471 2011-10-10 | FLARE-No. 1 Flare; SRU 1 | Cause: There was sudden unexpected loss of O2 supply from Air Products causing SRU1 to immediately shut down. Acid gas (SO2 and H2S) was released intermittently through Number 1 Flare. SRU 1 was sole operating SRU at the time of incident, as SRU 2 was shutdown for maintenance. Followup: No Notes: Steam controllers have been repaired and rebuilt. There was also an evaluation of alarm changes to provide more response time. EPA Acid Gas Flaring report included. LDEQ conducted an investigation in response to this incident on 12/8/11. | 164,891.0 pounds |
| 134066 2011-09-18 | No information given | Cause: Sulfur dioxide released to atmosphere with no RQ/BRQ Followup: No Notes: Chalette Refining provided a courtesy notification to your office regarding a release of sulfur dioxide to the atmosphere on September 18, 2011. After further review, there were no RQ exceedances as a result of this event. | |
| 133880 2011-09-11 | FLARE: Flare No. 1 | Cause: A packing leak developed on the seal of the fire eye cleaning device causing it to malfunction during routine maintenance and allowed combustion gases to escape to the atmosphere and shutting down Train 1 of the SRU (Sulfur Recovery Unit) sending acid gases to the FGM. Flared from flare 1 at a reportable quantity of H2S/SO2. Followup: No Notes: Unit operations were adjusted to minimize the duration and severity of flaring. The SRU Train 1 was switched to oxygen mode so it could process refinery acid gas. Sulfur pit vents on both trains were opened until SRU 1 could process them. To prevcnt this from happening again a re-engineered fire-eye cleaning tool will be constructed. This is expected to be completed by December 31, 2011. CRLLC will not utilize the fire-eye cleaning tool until modification to the tool has been completed. Two employees received first aid treatment. No chronic or acute health risks are anticipated as a result of this release. There was no emergency condition as a result of this release. NO SPOC or LDEQ report. | 36,579.0 pounds |
| 133625 2011-09-01 | No information given | Cause: A heavy rain occurred then the sulfur plant started having problems around 1130 hrs. They started seeing emissions. They believe it is due to an instrument malfunction. Followup: No Notes: Chalmette Refining LLC provided a courtesy notification to the LDEQ regarding a release of sulfur dioxide to the atmosphere on September 1, 2011. After further review, there were no RQ exceedances or permit violations as a result of this event. | |
| 133061 2011-08-11 | FLARE: Unspecified location | Cause: A high pressure waste gas flaring system shut down. The flare gas recovery compressor could not handle the load and sulfur dioxide was released into the atmosphere. Followup: No Notes: The unit rates were reduced to lower the amounts going to the flare. | |
| 132776 2011-07-29 | Flare 1 | Cause: On 01/28/11, at approximately 9:00am, the amine unit was being taken out of service for a planned maintenance activity. During the course of the shutdown, the DGA circulation in the contactor decreased. The reduced flow occurred concurrent with the loss of the LPG compressor. As a result, there was an H2S breakthrough to the refinery fuel gas system at approximately 1 minute. This event resulted in 86 lbs of excess SO2 emissions. Followup: No Notes: Fuel Gas incident- The shift leader recognized the problem within 15 minutes of the start of the event and immediately increased circulation to stop the H2S breakthrough and mitigate the SO2 emissions potential. Updated procedures to ensure shutdown activities include awareness of circulation rate and interaction with other unit operators. Refresher training will be conducted with unit personnel on revised procedure. In a separate event at 12:58am, the flare gas management compressors briefly shutdown due to elevated molecular weight (MW) gas which resulted in increased SO2 emissions from the fired combustion units of 481 lbs excess SO2 | 567.0 pounds |
| 132721 2011-07-23 | Flare | Cause: On July 23, 2011 at approcimately 23:33 hours, a safety valve on the propane/polypropylene mix drum, D9007 relieved to the No. 1 Flare, resulting in intermittent flaring, and consequently resulting in emission of sulfur dioxide in excess of the reportable quantity of 500 lbs. Incident 11-04337 occurring on July 21, 2011 caused a buildup of hydrocarbons in the compressor seal water decreasing the capacity of the compressors which normally have the capacity to contain this volume. Followup: No Notes: The seal water on the FRM compressors was changed out as the hydrocarbon buildup contributed to the flaring. Pressure build up in the spheres occurred before the seal water could be changed out in the compressors causing intermittent flaring. The venting could not be delayed as it would have been a process safety issue. Flaring does not normally occur from these procedures. | 1,010.0 pounds |
| 132609 2011-07-20 | Flare: Unspecified location | Cause: A sphere over pressured and dumped to the flare. Pressure safety valve lifted and went to flare. Followup: No Notes: The sphere was isolated away from the flare. | |
| 132188 2011-07-09 | No Information Given | Cause: Planned unit shutdown for maintenance operations. Followup: No Notes: BRQ: According to the Refinery Letter, "unit operations and shutdown timing were adjusted to minimize environmental impact." | 1,949.0 pounds |
| 131213 2011-05-13 | FLARE-No. 1 Flare; Sulfur Recovery Unit (SRU) Train II | Cause: Air Products, third party oxygen supplier, experienced a malfunction of an emergency safety device. Oxygen supply was lost to Train II of SRU. The Flare Gas Management System shutdown because of acid gas from the DGA strippers. Two follow-up letters dated 10/25/11 and 11/15/11. Followup: Yes Notes: Report states that Air Products re-secured a loose control relay and has ordered a new relay that will fit more securely. EPA Acid-Gas Flaring incident report included. Follow-up letters: A new control relay has been obtained and will be installed in Q4 2012 during a planned outage. | 117,344.0 pounds |
| 130963 2011-04-27 | No. 2 Coker and Cat Feed Hydrotreater (CFHT) | Cause: Unscheduled outages of the No. 2 Coker and Cat Feed Hydrotreater resulted from a temperature change due to operating on combustion air resulted in the release of sulfur dioxide. Followup: Yes Notes: RQ. EPA Consent Decree report included. Immediate remedial actions taken: Upstream unit rates were reduced, the Sour Water Stripper unit was shut down, and SRU conditions were adjusted. Further action: 1)Refresher training has been conducted with increased emphasis on the importance of monitoring the No. 1 Converter temperature closely during train transitions to combustion air with pit vapor to prevent recurrence. 2)Procedure to switch from O2-mode to air-mode was modified. 3)MDEA lean loading field testing to be moved to refinery lab, with upgraded analysis procedures 4)Evaluate project to operate SRU units in partial O2-enrichment mode to reduce environmental vulnerability On January 6, 2012 the refinery sent follow-up notification that all action items related to the April 27, 2011 Tail Gas Incident has been completed. | 1,150.8 pounds |
| 130697 2011-04-18 | Fluid Catalytic Cracker (FCC) Unit | Cause: According to LDEQ, there was "a pump shut down due to a power trip. After thepump shut down, pressure levels built in the absorber column," which resulted in a release of sulfur dioxide. Followup: No Notes: BRQ According to LDEQ, "There is a back-up pump in case of emergency where flow was restored during the... flaring." No further information given. | 187.0 pounds |
| 129573 2011-03-01 | Flare | Cause: Malfunction of the compressor spillback valve. The Fluidized Catalytic Cracker (FCC) main fractionator overhead accumulator pressure control valve (79PC502F) began to open to flare due to a sudden increase in pressure in the accumulator, which led to flaring at the #1 Flare. The sudden pressure increase was the result of a stuck compressor spillback valve. Followup: No Notes: Feed rate to the unit was reduced, pressure was reduced and the pressure control valve setpoint was raised. CRLLC has determined the cause of this release to be a malfunction of the compressor spillback valve. The valve has been evaluated by a technician and the pressure control valve setpoints are being reviewed. | 1,014.0 pounds |
| 129381 2011-02-23 | PSV Valve | Cause: State Police report states a PSV valve may be leaking and that cause of leak is under investigation.
LDEQ Report states PSV valve was leaking to flare system. Followup: No Notes: BRQ | |
| 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. Followup: No Notes: The high pressure waste gas system had been restored by the time of the LDEQ Incident Report. | 5,769.0 pounds | |
| 138541 2012-04-03 | #1 Flare | Cause: A high molecular weight gas was routed to the flare gas management system, which prevented the compressor from being able to pump the gas and caused the flare to open. Followup: Yes Notes: To stop the discharge, feed rate to the unit was reduced, reducing pressure, and eventually ending the release. A representative from Chalmette Refining contacted LDEQ Emergency Response on 4/4/12 when an all-clear was called, also providing the total release quantity of sulfur dioxide. No fire, injuries, or fatalities resulted from this incident | 1,022.0 pounds |
