Leak on the HDS Unit fans caused spill to the ground. Emissions resulted from the spill to the ground, the release to the atmosphere and from the unit de-pressure to the No. 2 flare.
At approximately 04:07 hours on 11/17/05, refinery personnel discovered a leak on the Hydrodesulphurization (HDS) Unit fin-fans. Approximately 9.3 barrels of Distillate range material spilled to the ground. Emissions resulted from the spill to the ground, the release to the atmosphere, and from the unit de-pressure to the no. 2 flare. Chalmette Refinery rescinded the 11/17/05 notifications for NO, NO2, VOC, SO2 and H2S since the estimated amounts were less than the reportable quantity of 10lbs. They estimate that approximately 1.93 and 0.21 pounds of Nitric Oxide (NO) and Nitrogen Dioxide (nO2), respectively, were released to the atmosphere during the 11/17/05 event. Therefore, notification for Nitrous Oxides (NOx) was not required. Calculations performed after the incident indicated that a greater than reportable quantity of oil was spilled to the ground during this incident, and as such, emissions calculations for the oil spill are included in the follow-up report. Hydrogen Sulfide and Compressed Flammable Gas/Non-speciated VOCs released to atmosphere through the leak; Sulfur Dioxide and compressed flammable gas/non-speciated VOCs released to atmosphere through the NO. 2 flare; oil spill to ground with VOC volatilization to atmosphere. The HDS Unit was shutdown and de-pressured to the no. 2 flare to minimize the impact of the leak. A pipe clamp was installed, stopping the leak.

Volatile Organic Compounds (VOCs) - 1,862 pounds
Cause of Problem: Equipment Failure

During periodic rounds and gauging of tank 72 (D-72), refinery operations personnel observed slop oil overflowing from tank 72. It was determined that the tank had experienced an unanticipated sure in inventory between manual gauging events. The release was caused by the unanticipated malfunction of tank gauge equipment.
Chalmette Refining reported a release of oil (Slop Oil) and Benzene on 1/7/05. Calculations performed after the incident indicate the greater than a reportable quantity of Volatile Organic Compounds (VOCs) was also released during this incident, as such, emissions calculations for VOCs are included in this follow-up report. Hurricane Katrina caused damage to the electronic tank gauge (telepulse) system for tank 72 (D-72). As mitigation step, periodic manual gauging of D-72 was implemented based on anticipated tank inventory movement. At approximately 2345 hours on 11/7/05 during periodic rounds and gauging of tank 72, refinery operations personnel observed slop oil overflowing from tank 72. It was determined that the tank had experienced an unanticipated surge in inventory between manual gauging events. Since the tank receives inventory from multiple sources the reason for the unexpected increase in inventory was no immediately evident. Oil (as slop oil) released from refinery tank 72 (D-72) via overflow. Slop oil and water was released to the carthen tank containment dike. A portion of the slop oil components evaporated to the air. Transfer to tank the was stopped ending the incident. Transfer out of the tank to the other storage was initiated, lowering the level. Vacuum Trucks were dispatched in order to recover released liquids. The electronic tank gauge for tank 72 has been repaired and placed back in service. Liquid released was contained within the tank dike area and recovered via vacuum truck. Refinery personnel have begun removing soils that appear to have come in contact with spilled slop oil and will remove all stained soil for off site disposal. Currently, migration outside of the tank dike or to groundwater is not suspected. Released liquids that did not volatilize were contained within the tank dike area. Liquids were recovered via vacuum truck and placed into refinery tankage for re-processing. Excavated soils are being placed in roll-off containers, characterized and properly disposed of.

#2 flare was smoking. In an attempt to reduce the smoke, the flare steam was engaged. Repairs to the flare steam system from the Hurricane Katrina shutdown were still ongoing. The steam was engaged with allowance for draining the lines of condensate prior to putting the steam to the flare.. there was some water carryover, resulting in intermittent steam and a surge of steam which extinguished the flare and pilots.
This letter is in regard to calls made by the Chalmette Refinery, notifying of a release of compressed flammable gas/volatile organic compounds (VOCs) on 10/13/05.At 15:00, the #2 flare was smoking. In an attempt to reduce the smoke, the flare steam was engaged. Repairs to the flare steam system from the Hurricane Katrina shutdown were still ongoing. The steam was engaged with allowance for draining the lines of condensate prior to putting the steam to the flare. There was some water carryover, resulting in intermittent steam and a surge of steam which extinguished the flare and pilots. Initial investigation indicated that too few drains were present on the steam line to eliminate the quantity of water created, and there were leaking isolation valved on the steam line. Chalmette will establish review the procedure for commissioning steam to the flare after shutdown to ensure that the line is drained prior to putting steam to the tip of the flare and that the line is checked for valve leaks and pluggings. affected refinery personnel will be trained regarding updates to applicable procedures. The refinery anticipates that these measures will minimize the likelihood of a recurrence of an incident due to the same root cause in the future. The flare was re-lit and the steam was adjusted and stabilized, ending the incident. Initial investigation indicates that too few drains were present on the steam line to eliminate the quality of water created, and there were leaking isolation valves onthe steam line. CRLLC will establish and review the procedure for commissioning steam to the flare after shutdown and will train affected personnel for updated procedures.

Cause of Problem: Weather

HURRICANE KATRINA (storm) Release of sulfur dioxide, nitric oxide, nitrogen dioxide, and hydrogen sulfide was due to overpressurization of the FCC debutanizer overhead condenser, resulting in flaring and a small ground fire.
This follow-up letter has been delayed due to Hurricane Katrina. This is a notification that the total refinery shutdown resulted in an evacuation of the refinery and the potential emergency release of wastewater from the wastewater treatment plant outfall. Chalmette Refining conducted a detailed analysis of emissions resulting from the refinery shutdown for Hurricane Ivan in September 204. Since the refinery shutdown for Hurricane Katrina was similar, they have assumed that the quantities released during Katrina shutdown are the same as the Ivan shutdown. Chalmette Refinery is rescinding the 8/27/05 notifications for S02, H2S, NO2, and hydrocarbons (non-speciated VOCs). Upon further review, the facility claims that the total amounts were estimated to be less that the reportable quantities (RQ= 100 lbs). The original estimated quantity of NO was 467 lbs, and was later changed to be estimated at 74 lbs. Shutdown was undertaken in preparation for the forecasted potential for Hurricane conditions. Operations were conducted in order to minimize emissions while maintaining a safe and orderly shutdown. Emissions resulted from gas flaring, fuel gas quality changes, and standby operation modes necessitated by the shutdown. Sometime after Hurricane Katrina, the pilots on the flares were extinguished. By that time, predominantly natural gas was being flared and no reportable quantities were exceeded.The pilots were re-lit on all flares by September 8, 2005 At approximately 12:00 hours on 8/27/05, the FCC debutanizer overhead condenser overpressured due to a failure with a pressure controller, resulting in flaring and a small ground fire. For the FCC, the tower was returned to normal pressure and the pressure transmitter on the overhead condenser was repaired. The small ground fire was extinguished.

Flammable Liquid - 0 pounds
Cause of Problem: Human Factors

During a transfer of gasoline to tank 6303 (D-6303), gasoline was observed leaking from the side of tank 6305 (D-6305). Tank 6305 later was determined to have been unintentionally filled past capacity, causing overflow to leak through tank side vent. 123,836 pounds of gasoline released to the ground. Report documents amounts volatilized. However, total amounts released to environment in report attached do not add up to 123,836. States 123,836 lbs of flammable organic liquid 'including' the benzene, xylene, and VOCs.
Contained liquid in tank area and recovered via vacuum truck. Water and foam applied to minimize volatilization and migration into soil. Note that report attached to letter contains information about other compounds released to the environment. Air monitoring report and soil sampling report were requested and provided by letters dated 1/18/05 and 2/28/05, which are attached to the report file. Field interview form states that 582 bbls of gasoline were released, but everything else states 481 bbls. The quantities of pollutants listed in this report were the portion that Chalmette Refinery claims were volatilized; under the Reportability of Liquid Product and Chemical Spills, the Notification Instructions lists that the quantities released were 123,836 lbs of oil (gas), 2748 lbs flammable gases, 980.8 lbs benzene, 8173.2 lbs xylenes. Further in report it is declared that 2747.7 lbs of pollutants were released offsite. Accutest Lab summary of soil testing adds Toluene and TPH-GRO to pollutant list.
