2013-09-21
Point Source(s):
Wastewater treatment unit

Pollutant(s):
Benzene - 33 pounds
Xylene - BRQ
Ethylbenzene - BRQ
Toluene - BRQ
Cause of Problem: Weather

This incident involved a Benzene release associated with wastewater diversion CITGO's wastewater treatment plant. This wastewater diversion occurred as a result of a flash flood heavy rain event. CITGO diverted the wastewater into a concrete diked containment area surrounding the wastewater tanks. According to CITGO, the wastewater diversion was necessary to avoid overfilling of stormwater and equalization tanks. One of the WWTP Equalization Tanks (TK 310) had been out of service for inspection/maintenance going into the subject rainfall event.
Wastewater processing rates were maximized and material diverted to diked area was pumped to controlled storage as tankage became available. CITGO will be constructing a fourth wastewater storage tank as well as an additional API separator and aeration tank.

2013-07-02
Point Source(s):
Tank 182

Pollutant(s):
Propane - BRQ
Cause of Problem: Maintenance/Procedures

On July 7 at approximately 9:35 PM, a blowdown of the girbotol unit to Tank 182 caused a release of propane (C3 mix) to the air from Tank 182.
System was secured after discovery of release. No specific information given on remedial actions. A review of operating data from event showed no RQs exceeded.

2013-06-20
Point Source(s):
B502 Reactor D-SRU
Thermal Oxidizer

Pollutant(s):
Hydrogen Sulfide - BRQ
Sulfur Dioxide - BRQ
Sulfur Dioxide - 1,818 pounds
Cause of Problem: Equipment Failure

On June 20, a release of hydrogen sulfide and sulfur dioxide into the air was caused by a small leak from the B502 Reactor furnace in the D-Sulfur Recovery Unit was discovered.
The unit was shut down and the leak was repaired. According to CITGO, a review of the operating data from this event showed that no RQs were exceeded, but the start-up of the unit resulted in emissions that exceeded the RQ of 500 pounds for sulfur dioxide. During startup after the incident on June 22, the unit sent tail gas to the thermal oxidizer while heating up the catalyst beds with natural gas. Sulfur dioxide emissions during this time was 1818 pounds. Pursuant to Paragraph 93a of the NSR Consent Decree, stipulated penalties shall not apply to a tail gas incident attributable to the scheduled start-up of an individual train at the SRP located at the Lake Charles Refinery, provided that CITGO demonstrates that it has implemented good air pollution control practices.

2013-06-10
Point Source(s):
Tank 701

Pollutant(s):
Oil - 28 gallons
Cause of Problem: Seal or Gasket

On June 10, a leak in a flange off of Tank 701, a feed tank containing light cycle oil or diesel, was discovered.
Flange was tightened and the leak was secured immediately. Clean up of the soil was completed by June 14. One roll off box of dirt was removed.
No LDEQ Number Available

2013-06-06
Point Source(s):
LCMC A-Dock

Pollutant(s):
Diesel Fuel - 0 gallons
Cause of Problem: Human Factors

On June 6, a mixture of water and diesel was spilled from the drip pan containment by a contractor to the Calcasieu River during maintanance activities on the CITGO Petroleum Corporation LCMC A-Dock creating a sheen.
The maintenance activity was stopped and SPCC measure were taken to contain the sheen. To prevent reoccurrence, maintenance procedures are under review.

2013-05-09
Point Source(s):
No information Given

Pollutant(s):
Flammable Gas - BRQ
Cause of Problem: Maintenance/Procedures

On May 9, 2013, CITGO Petroleum Complex notified LDEQ's Single Point of Contact of a flammable gas (propane) release during maintenance on a pilot gas for a flare. Purge gas was used to keep the flare lit. As a result of high winds, the pilot light went out and approximately 2800 lbs of gas was released to the atmosphere. The amount released was below the reportable quantity; therefore CITGO is regarding this as a courtesy call.

Point Source(s):
Coker I JC-106

Pollutant(s):
Sour Gas - BRQ
Nitric Oxide - BRQ
Hydrogen Sulfide - BRQ
Cause of Problem: Process Upset

On March 13, 203 CITGO Lake Charles Manufacturing Complex had a flaring event involving the Coker 1 JC-106 compressor. The JC-106 compressor shut down requiring flaring of sour gas through the b5 flare. Hydrogen sulfide and nitric oxide were mentioned in the LDEQ report.
The refinery letter stated that no reportable quantities had been exceeded, with no additional information on specific substances.
147293

2013-03-12
Point Source(s):
Distillate line near B-Reformer unit

Pollutant(s):
Flammable Gas - 2,667 pounds
Benzene - 59 pounds
Cause of Problem: Corrosion

On March 12, 2013, a leak was discovered on a distillate pipe, in the pipe rack east of the B-Reformer unit. It is believed that the leak was caused by internal corrosion of the distillate line. The event is currently under investigation.
Equipment which utilize the line were either shutdown or operated in such a way as to minimize the amount of material entering this line. Once minimized, the affected area of pipe was isolated and replaced with new piping. The affected area of piping has been changed out with new piping. In addition, this incident is under investigation.

2013-02-01
Point Source(s):
Tank 182

Pollutant(s):
Flammable Gas - 12,000 pounds
Cause of Problem: Under Investigation

On February 1, 2013, hydrocarbon vapors were discovered near tank 182. Tank 182 is a spent caustic tank which receives a portion of its feed from the Girbotol unit. It was determined that a spent caustic, flow control valve in the Girbotol unit had been manually opened to an extent and time which allowed a propane/ propylene mixture to migrate to tank 182. The propane/ propylene mixture was then released from tank 182. This event is currently under investigation.
Release calculations indicate that reportable quantities of volatile organic compounds (VOC) and flammable gas were exceeded. The spent caustic line was closed preventing any additional release of C3 mix to tank 182. Of the 12,000 lbs of flammable gas released, 11,700 lbs were VOCs.
