Maphtha migrated across sOil and accumulated in an onsite concrete drain pipe. | Line was isolated and released material was contained within refinery property and recovered for proper handling. Excavated sOils were containerized and stored on site. Put in place a piping inspecion program to routinely assess and inspect pipes in order to reduce the likelihood of an incident occurring due to the same root cause. |
| 91727 2006-10-29 | Point Source(s): AE-AOA-05-0109 EPN 28 Pollutant(s):Nitrogen Oxide - 24 pounds | Cause of Problem: Equipment Failure mechanical failure in the check valve servicing the K-7702 Compressor. Make-up Discharge Check Valve mechanically failed and allowed the system to pressure back into the compressor.

But, found that o-ring was bad and needed replacing, etc. Letter sent 12 18 06 rescinds prior notifications and revises amts emitted to those listed at left. Had been NOx 564 lbs ; VOC 1925 lbs |
| 91457 2006-10-17 | Point Source(s): AE-AOA-05-0109 EPN 29 Pollutant(s):Sulfur Dioxide - 30 pounds Nitrogen Oxide - 8,293 pounds | Cause of Problem: Maintenance/Procedures release occurs during major turn around of refinery. Planned system outages created higher than usual operating pressure on the WGS and AMU. Additionally, on 10/13, the stream was re-routed (misaligned) through a line with an unidentified check valve. Subsequent attempts to push liquid through the AMU line resulted in increased pressure on the WGS. | Investigation ongoing. PSV set pressure was raised to allow for higher head pressure events at WGS without flaring. Detailed investigation ongoing. |
| 91273 2006-10-10 | Point Source(s): Thermal Oxidizer and Flare 1 - AE-AOA-05-0109 EPN 46 Pollutant(s):Nitrogen Dioxide - 352 pounds Hydrogen Sulfide - 2,917 pounds Nitrogen Oxide - 3,198 pounds Sulfur Dioxide - 1,068,405 pounds | Cause of Problem: Process Upset Discharges came from THOX and Flare 1. The Amine and Sulfur Recovery Units were upset. It was determined that hydrocarbons contaminated the Diglycolamine (DGA¨) and required both units to be taken offline. The upset caused excess emissions from the SRU 1 Thermal Oxidizer (THOX). Sulfer Plant feed was diverted to the refinery safety flare system while the conditions which cause the upset were isloated and remedied. CRLLC reduced the rates of acid gas productin units to minimum and lowered total sufer content of remaining feed, within refinery capability. | CITIZEN COMPLAINT COINCIDES WITH INCIDENT - all acid gas producing units were cut back to minimum rates. The source of hydrocarbon in the DGA system was isolated and then purged. The refinery has initiated an investigation into the cause of this incident.

| 86695 2006-03-24 | Point Source(s): Flare Pollutant(s):Nitrogen Oxide - BRQ | Cause of Problem: Other power failureblip on shared electrical system resulted in 14 minute outage | Letter written to rescind notification of 3/24/6 |
| 86612 2006-03-20 | Point Source(s): Emergency Flare System AE-AOA-05-0109 EPN 29 Pollutant(s):Sulfur Dioxide - 2,204 pounds | Cause of Problem: Start Up, Shut Down compressor 1(K-400) automatically shut down, lowering waste gas processing capacity and causing overpressure to the emergency flare system. Later, waste gas compressor number 2 (K-401) automatically shut down causing the waste gas system to further overpressure to the emergency flare system. | the refinery has initiated an investigation, appropriate measures will be taken in order to prevent a recurrence due to the same cause. |
| 86447 2006-03-13 | Point Source(s): AE-AOA-05-0109 Pollutant(s):Sulfur Dioxide - 680 pounds Nitrogen Dioxide - 1,821 pounds Nitrogen Oxide - 16,393 pounds | Cause of Problem: Other loss of power resulted in the unplanned upset of the refinery. External power supplied by Entergy was lost due to activity external to refinery operations. Release from Nos. 1 and 2 Flares. | Specific action taken: met with Entergy to stress the impact of this incident and request that appropriate measures be taken in order to prevent a recurrence. |
| 86380 2006-03-10 | Point Source(s): Pipe Pollutant(s):Sour Water - 250 gallons | Cause of Problem: Corrosion pipe carrying sour water developed a corrosion leak. | Leak fixed with a clamp. Line was returned to service after clamping. Pipe was scheduled for inspection and maintenance. |
| 86817 2006-02-28 | Point Source(s): NA Pollutant(s):Hydrogen Sulfide - 139 pounds | Cause of Problem: Equipment Failure unanticipated failure cause a leak in instrument piping on a sight glass at the Sour Water Stripper Unit. The unanticipated leak caused the release of stripper overhead gasses to the atmosphere. | Piping was repaired and unit was returned to service. A review of the Sour Water Stripper Unit condensate flush piping will be conducted. |
| 86075 2006-02-27 | Point Source(s): Bleeder valve plug in truck loading rack area Pollutant(s):Diesel Fuel - 70 gallons - 0 pounds | Cause of Problem: Piping or Tubing a bleeder valve failed on a line leading to the truck loading facility | DEQ report with no corresponding letter from CRLLC. Valve was quickly isolated and replaced. Liquid was recovered via vacuum. |
| 85953 2006-02-21 | Point Source(s): AE-AOA-05-0109 Pollutant(s):Nitric Oxide - 25 pounds | Cause of Problem: Start Up, Shut Down during startup of liquefied Petrol. Gas compressor, an unexpected liquid was present in the compressor discharge piping. This caused an unexpected upset resulting in over pressurization of the refinery fuel system. No. 2 Flare. | the refinery has initiated an investigation, appropriate measures will be taken in order to prevent a recurrence due to the same cause. |
| 85863 2006-02-15 | Point Source(s): Tank 75 Roof Vent Pollutant(s):Heavy Vacuum Gas Oil - BRQ | Cause of Problem: Equipment Failure Small fire from a tank vent. Fire originated at the roof of tank 75. | Letter written to rescind notification of 2/14/06. Extinguished immediately. |
| 85834 2006-02-15 | Point Source(s): Waste Gas Compressor Pollutant(s):Sulfur Dioxide - BRQ Nitrogen Oxide - BRQ Nitrogen Dioxide - BRQ | Cause of Problem: Process Upset process equipment allowed light ends to enter Tank 75 during an upset. The tank vent ignited briefly during this period. | Letter written to rescind notification of 2/15/06 |
| 85837 2006-02-14 | Point Source(s): No information given Pollutant(s):Sulfur Dioxide - 322 pounds | Cause of Problem: No Information Given No information given | Letter written to rescind notification of 2/14/06 |
| 85682 2006-02-08 | Point Source(s): No information given Pollutant(s):Non-Flammable Organic Liquid - BRQ | Cause of Problem: No Information Given No information given | Letter written to rescind notification of 2/8/06 |
| 85641 2006-02-06 | Point Source(s): No information given Pollutant(s):Nitric Oxide - BRQ | Cause of Problem: No Information Given No information given | Letter written to rescind notification of 2/6/06 |
| 85454 2006-01-29 | Point Source(s): Thermal Oxidizer AE-AOA-05-0109 EPN 46 Pollutant(s):Sulfur Dioxide - 3,141 pounds | Cause of Problem: Process Upset steam leak into SRUTR1 prcoess necessitated shutdown and transfer to another unit | refinery has initiated an investigation into the cause. Operations were conducted to minimize emissions. Safe and orderly shutdown to reduce impact. |
