Point Source(s):
D acid cooler
Flare #1

Pollutant(s):
Hydrogen Flouride - 218 pounds
Sulfur Dioxide - 10,360 pounds
Cause of Problem: Equipment Failure

On October 30, personnel identified increased fluoride levels of routine samples at the battery limits of the Alkylation unit in the cooling water return system from 0.39 parts per million (ppm) to 0.5 ppm. Based on preliminary findings, the "D" acid cooler at the alkylation unit appears to have developed a leak. Sampling conducted at Outfall 013, which measures fluoride concentration, suggests a neutral pH, dilute solution of HF was leaking from a heat exchanger in the cooling water system and discharged through the outfall. CRLLC personnel began to shutdown the unit in order to isolate the cooler on October 31. As a result of the leak and subsequent shutdown of the unit, intermittent flaring occurred at the #1 Flare beginning on October 31 and ending on November 2.
The Alkylation Unit was shut down in a safe and controlled manner in order to isolate the acid cooler. The acid cooler is being inspected and repaired to minimize the risk of recurrence. The rates were reduced and the acid was evacuated from the unit. Fluoride samples were measured from the cooling water effluent throughout the shutdown of the unit. The pH of Outfall 013 was continuously monitored.

Sulfur Dioxide - 2,442 pounds
Cause of Problem: Maintenance/Procedures

On Monday, October 7, 2013 at approximately 09:03 hours, the flare gas management (FGM) compressors overpressured from a planned maintenance shutdown of the waste gas system (WGS) resulting in the intermittent staging of the #1 Flare. The WGS was being taken temporarily out of service for maintenance of the electrical switchgear. During the WGS outage, the waste gas is routed to the FGM compressors for recovery. The increased flow of the waste gas to the FGM compressors caused an overpressure of the recovery system and staged the #1 Flare. According to the 01/10/14 follow up letter the WGS was being taken temporarily out of service for maintenance of an electrical switchgear. During WGS outage, waste gas is routed to the flare gas management (FGM) system compressors for recovery system, resulting in the intermittent staging of the # 1 Flare.
The maintenance of the electrical switchgear was completed and the compressors were returned to service to eliminate the gas being routed to the recovery system. All three flare gas recovery compressors were online to minimize flaring during the event. The planned maintenance activity for the WGS will increase the reliability of the system and reduce the likelihood of waste gas being routed to the flare gas recovery system. According to the LDEQ incident report "this event is considered reasonably unforeseeable, therefore qualifies as an upset in accordance with LAC 33:507J Upset Conditions"

Point Source(s):
Tank Farm, Tank 52

Pollutant(s):
Benzene - 154 pounds
Hydrocarbon - 181 gallons
Cause of Problem: Seal or Gasket

On October 1, 2013, personnel identified a leak at Tank 52 charge pump (G-9053) which was determined to be from a mechanical seal failure. The valve on the suction side of the pump malfunctioned.
The pump was immediately turned off and the valves on the suction and discharge sides of the pump were closed to attempt to isolate the leak from the pump. The valve on the suctions side of the pump malfunctioned and required the use of water to pressure the hydrocarbon material back to Tank 52 until the line could be isolated. The pump will be repaired and inspected prior to being put back in to service.

2013-07-29
Point Source(s):
Flare #1

Pollutant(s):
Sulfur Dioxide - 1,666 pounds
Cause of Problem: Maintenance/Procedures

On Thursday, July 29, 2013, at approximately 1352 hours, the flare gas management (FGM) compressors over pressured from a planned maintenance shutdown of the waste gas compressor (K406) resulting in the staging of the #1 Flare. K406 was being taken temporarily out of service to repair piping on the sight glass and bottom drain piping for the cooling water day tank. During the K406 outage, the waste gas is routed to the FGM compressors for recovery. The increased flow of the waste gas to the FGM compressors caused an overpressure of the recovery system and stages the #1 Flare. On 8/28/2013 LDEQ conducted "onsite discussions" with Chalmette supervisors about three accidents relating to the WGC and FGC unit between 7/25-7/28 (149927, 149989, 150004).
K406 was repaired and returned to service to eliminate the gas being routed to the recovery system. The planned maintenance activity for K406 will increase the reliability of the waste gas system and reduce the likelihood of waste gas being routed to the flare gas recovery system.
149989

2013-07-28
Point Source(s):
Flare #1

Pollutant(s):
Sulfur Dioxide - 1,548 pounds
Cause of Problem: Equipment Failure

On Sunday, July 28, 2013, at approximately 0349 hours, the flare gas management (FGM) compressors began to lose suction and stopped pumping resulting in the staging of the #1 Flare for approximately 7 minutes. With the inability of the compressors to pump reliably, a water change out was required to get the system back in normal and stable operation. This process intermittent flaring between 10:44 and 18:11.
Emissions were minimized as much as possible and the FGM compressors were returned to normal operation as soon as possible. An ongoing evaluation of the equipment during the event revealed the flare gas recovery water purge capability was restricted. This resulted in increased unreliability of the compressors due to the reduced discharge rate of the high molecular weight water recirculating in the system. The water purge capability was restored on 7/29 and should result in faster recovery times from unplanned high molecular weight gas events. LDEQ conducted "onsite discussions" with Chalmette Environmental and business supervisor related to three accidents related to the FGC and WGC units between 7/25-7/28 (149927, 149989, 150004) on 8/28/2013.

Point Source(s):
Flare #1

Pollutant(s):
Sulfur Dioxide - 10,860 pounds
Cause of Problem: Process Upset

On Thursday, July 25, 2013, the flare gas management (FGM) compressors began to lose suction and stopped pumping resulting in the staging of the #1 Flare. Prior to this even, a planned venting of pump G7908 occurred and is suspected to have caused an increased flow of higher molecular weight material to the compressor system. Concurrently, waste gas compressor (K406) was out of service from a prior malfunction causing waste gas to be routed to the FGM system. The increased flow of the waste gas caused an overpressure of the recovery system and staged the #1 Flare.
Emissions were minimized as much as possible and the FGM compressors were returned to normal operation as soon as possible. K406 was repaired and returned to service to reduce the gas being routed to the recovery system. An evaluation of the equipment during the event revealed the flare gas recovery water purge capability was restricted. This resulted in increased unreliability of the compressors due to the reduced discharge rate of the high molecular weight water recirculating in the system. The water purge capability was restored on 7/29 and should result in faster recovery times from unplanned high molecular weight gas events. Waste gas system compressor reliability and water purge capability will be reviewed to identify and evaluate improvement options. LDEQ conducted "onsite discussions" with Chalmette Environmental and business supervisor related to three accidents related to the FGC and WGC units between 7/25-7/28 (149927, 149989, 150004) on 8/28/2013.

2013-05-12
Point Source(s):
FGM compressor, #1 Flare

Pollutant(s):
Sulfur Dioxide - 1,049 pounds
Cause of Problem: Instrument Failure

On Sunday, May 12, 2013, at approximately 19:25 hours, the flare gas management (FGM) compressors tripped on a high inlet separator drum liquid level which resulted in material being routed to the #1 Flare. An investigation revealed the liquid level instrumentation that controls the levels in the inlet separator drum had malfunctioned causing the liquid level control valve to close and the liquid level to rise. This occurred when the level instrument was reading at lower than the setpoint value and the valve closed to raise the liquid level although the level was already rising but could not be seen by the operator board. The computer logic is designed to shut down the flare gas compressors during high level liquid alarms which were detected by a triplicated high level system which is independent of the liquid level that controls the control valve to prevent damaging the equipment.
Steps were taken to minimize emissions as much as possible and return the FGM compressors to normal operation. The inlet separator drum level instrumentation was repaired and is now operating normally. Additional systems are being evaluated which would provide backup indicators of conditions that would fill the inlet separator drum.

Pollutant(s):
Lube Oil - 1 pounds
Cause of Problem: Corrosion

On Monday, April 15, 2013, at approximately 1745 hours, Chalmette Refinery L.L.C. (CRLLC) personnel observed a small visible sheen at Outfall 012 due to small, intermittent droplets of oil, immediate notifications were made to the appropriate agencies and US Environmental deployed containment and absorbent boom to contain and collect the sheen. An investigation determined that the source of the leak was from the lube oil cooler exchanger E464 for natural gas motor K401. The exchanger was immediately isolated at 1815 hours. The root cause of the failure was determined to be chloride stress corrosion cracking and chloride pitting after visual inspection of the pipe. Lube oil was released to the river as a liquid.
Exchanger E464 was immediately isolated once it was determined to be the source of the leak. Trace, residual droplets still in the pipe after the exchanger system was isolated were observed until approximately 1100 hours on April 16, 2013. The root cause of the failure was determined to be chloride stress corrosion cracking and chloride pitting after visual inspection of the pipe. The metallurgy was changed to more chloride resistant material to prevent future recurrence. The company classified this accident as exceeding state police and DEQ RQs, but the amount reportedly released was less than the 1 barrel (42 gallon) RQ. LABB has accessed the 60 day follow up, but not the initial written discharge which was dated 4/21/13.

Benzene - BRQ
Cause of Problem: Corrosion

On Wednesday, April 3, 2013 at approximately 0145, a Chalmette Refining, L.L.C. (CRLLC) operator noticed odors around the waste water treatment plant (WWTP) shelter. At 0225, CRLLC was notified by St. Bernard Parish Sheriff's Office of a community complaint regarding a potential odor. The potential odor issue was communicated to relevant supervisors during the 0400 shift change, and operators continued to investigate the cause of odor during initial rounds. At approximately 0600, CRLLC personnel detected and reported potential odors, and intensified the investigation to identify the source and possible root cause. Personnel identified a leak from a pipe near Tank 5502 at 0645 and positively identified the source as a discharge pipe from the Flare 1 knockout drum at 0708. Moderate to heavy rain water and insulation covering the pipe, made it difficult to identify the leak source. The root cause of failure was determined to be highly localized internal pipe corrosion.
The pipe section with the leak was completely isolated at 0745, then vacuum trucks were utilized to clean up the spilled material. An engineered pipe clamp was installed to eliminate the pipe leak. To minimize any further potential community impacts from the odor, firefighting foam and suppressants were applied to the area possibly affected by the leak. Contaminated soil was remediated. In addition to determining root cause and actions regarding the pipe failure CRLCC has identified two actions to be taken to improve odor management and response: 1. Update guidelines for addressing community odor complaints. 2. Refresh personnel involved in this incident on expectations for documenting odor complaint activities/ observations on written shift change reports. The accident did result in offsite impact because ExxonMobil officials released this claims number for any community members affected: 866-752-6339. The facility made a small mention of the bad smell that permeated throughout the metro area in their letter to LDEQ. According to Exxon's April 10th report, "While there was no impact to ambient air quality standards set by the LDEQ and EPA to protect health and environment, the leak was malodorous given the 245 parts per million mercaptan levels of the sulfur compounds. While there was no impact to ambient air quality standards set by the LDEQ and EPA to protect health and the environment, the leak was malodorous given the 245 parts per million mercaptan levels of the sulfur compounds. The May 30th follow up updates this value to 127 parts per million. According to the 30 day follow up on May 30, 2013: On July 9, 2013 - CRLLC has pledged to participate in the Jefferson Parish LEPC meeting.

Point Source(s):
Crude 2 unit

Pollutant(s):
Crude Oil - 100 gallons
Benzene - 21 pounds
Cause of Problem: Piping or Tubing

On Sunday, January 20, 2013, at approximately 06:05 hours unit personnel identified a leak at the Crude 2 unit from a failed bleeder valve. A root cause failure analysis and investigation is ongoing and results will be provided in a 60-day follow-up report. Off-site monitoring by a third party contractor was initiated following identification of the leak and all results were non-detect for benzene and hydrogen sulfide. Low levels of VOC's were detected. The root cause of bleeder valve failure occurred from a failure mechanism of piping assembly due to high-cycle fatigue caused by line vibration during the PSV relief.
Upon discovery, the bleeder valve was isolated to stop the leak and cleanup of the area was immediately isolated. Notifications were made to shift supervision and the area was barricaded off to restrict access to the unit. All work was stopped and personnel were directed to a safe area. The appropriate agencies were notified. Internal and external monitoring was initiated. CRLLC has installed gussets on the bleeder valves of both desalter PSV's with similar design configurations. CrLLC will also ensure that all future Project Hazard Analysis (PHA) identify whether lines in vibrating service are adequately supported to avoid/mitigate any future re-occurrence of this root cause.

Point Source(s):


Pollutant(s):
Crude Oil - 1,512 gallons
Cause of Problem: Equipment Failure

Broken valve caused spill.
Material cleaned up and no offsite impacts noted, leak secured at time of first follow up call. A second follow call in the evening notified me that the facility was receiving notifications from citizens about oil on Co Rd S. Dense fog is suspected to be cause for material leaving site. Facility has set up a number for citizens to report any impacts. Clean up is a priority. A follow-up visit will be conducted once material has been cleaned. 36 barrels of crude oil were released.
