113697 2009-03-26 | Point Source(s): 3700 undergroudn piperack Pollutant(s):Oil (Sheen) - 0 | Cause of Problem: Piping or Tubing Leak from 3700 piperack underground. The insulation from #1 Fuel oil Dock Line underground had oil seeping out. An oil sheen was detected at outfall 006. | ES&H performed cleanup with vacuum trick. Pads were deployed under the pipe rack to contain spill, and everything was packed with clay earth in the dike. Area is monitored everyday and no more instances of oil on the ground. #1 Fuel Oil Dock line is out of service, and the underground piperack will be excavated for further investigation. |
113039 2009-03-16 | Point Source(s): #1 Fuel Dock Line and T-308 sump Pollutant(s):Diesel Fuel - 84 gallons | Cause of Problem: Weather Heavy rain caused residual oil entrained in the soil from a leak in #1 Fuel Oil Dock Line to cause sheen released from Outfall 006. Additionally, T-308 sump overflowed with diesel onsite in Area D. | NOTE: The originally submitted document on Match 21, 2009 had the wrong HAZMAT number. This was later corrected by a follow-up letter on March 26, 2009. However, the LDEQ number was not corrected. The sheen and the oil were cleaned up using absorbent booms, pads, and vacuum trucks. |
113432 2009-03-16 | Point Source(s): Outfall 006 Pollutant(s):No Information Given - 0 | Cause of Problem: Equipment Failure Control valve malfunctioned which caused an overflow of the EQ sump in Area A and B. | Overflow led to a ditch which releases to Bayou Verdine via Outfall 006. Water had no visible oil present and had a pH of 7. Samples were taken according to NPDES parameters and will be reported accordingly. |
113039 2009-02-26 | Point Source(s): P-808 Pollutant(s):Diesel Fuel - 84 gallons | Cause of Problem: Seal or Gasket A seal on pump P-808 in Area A ruptured spilling oil into secondary containment. | The pump was switched and P-808 was blocked in and secured. After the pump was isolated, floor sweep was spread, and a cleanup crew was called out to clean up the oil. |
112925 2009-02-23 | Point Source(s): #1/2 SRU Pollutant(s):Sulfur Dioxide and Sulfur Trioxide - 70 pounds | Cause of Problem: Start Up, Shut Down A boiler had an emergency shutdown due to a steam imbalance across the site. Various units that depend on steam to operate had rates rapidly reduced, and a release from #1/2 Sulfur Recovery Unit(SRU) was caused. | No information given |
112924 2009-02-21 | Point Source(s): Area A, B, and C heater stacks Pollutant(s):Sulfur Dioxide - 716 pounds | Cause of Problem: Process Upset The skimming of hydrocarbons at the #3 Flash Drum led to a foaming upset of the regenerator and inefficient H2S removal from the amine utilized in the high pressure fuel gas (HPFG). This caused a #3 Amine Regeneration Unit (ARU) system upset that resulted in combustion of refinery fuel gas with high H2S in the HPFG system. Ultimately, this caused SO2 to be released from fired heater stacks in Areas A, B, and C. | NOTE: Follow-up occurred on 3/31/09. Exceeds RQ. Immediate action taken was to add anti-foam to get the system back to normal and cleaning up the amine. Firing rates of heaters reduced to decrease SO2 released. Planned remedial action include increase frequency of skimming the #3 Amine Flash Drum to prevent sending large amounts of hydrocarbon to the regenerator all at once. |
112249 2009-01-23 | Point Source(s): Targa underground pipeline Pollutant(s):Kerosene - 420 gallons | Cause of Problem: Piping or Tubing Third party operated (Targa), underground pipeline was found ruptured. | ES&H performed cleanup of the oil leak site, and Targa was notified immediately to begin repairing the ruptured pipeline. Targa later called in the incident and is linked to #112264. |
113443 2009-01-17 | Point Source(s): camlock fitting of offloading rail car Pollutant(s):Sulfuric Acid - 153 gallons | Cause of Problem: Seal or Gasket Bad gasket on camlock fitting. Spill occurred during offloading of a rail car. | Exceeds RQ. Stopped offloading of acid. The acid was spilled into secondary containment and a small amount spilling onto the ground as low pH water. Conoco Phillips will include a step to check for camlot fitting in the standard operating procedure. |
111942 2009-01-12 | Point Source(s): exchanger X-430 Pollutant(s):Volatile Organic Compounds - 1,780 pounds | Cause of Problem: Piping or Tubing FCCU Vapor Recovery Unit exchanger X-430 developed a leak into the cooling water tower Y1/Y2 (EP-152). | Greater than RQ. X-430 was taken out of service. The exchanger bundle will be repaired, including replacement if needed. |
111853 2009-01-07 | Point Source(s): North Flare Pollutant(s):Sulfur Dioxide - BRQ Hydrogen Sulfide - BRQ Volatile Organic Compounds - BRQ | Cause of Problem: Equipment Failure A net gas compressor shut down due to high vibrations, this resulted in a high volume of material being sent to the north flare. | No information given |
111828 2009-01-07 | Point Source(s): North Flare Pollutant(s):Sulfur Dioxide - 0 Hydrogen Sulfide - 0 Volatile Organic Compounds (VOCs) - 0 | Cause of Problem: Start Up, Shut Down Net gas compressor in No. 10 reformer was shutdown due to high vibrations. The shut down caused high volumes of gas and liquids to the North Flare. This resulted in a surge of high pressure on the flare header line to the North Flare. | Immediately after the discharge, Conoco Phillips shut down Old Spanish Trail Roadway, and the North Flare was taken out of service. A Conoco personnel did a FLIR camera monitoring of the flare header line for VOC leakage. No leaks were found. LDEQ personnel were dispatched to the site later in the day after the discharge. They collected a summa canister air sample offsite and downwind of the North Flare. The canister did not detect any readings. Samples of ditch water was collected by Conoco Phillips on the north side of Old Spanish Trail on Sasol property. The water samples of SO2 was detected to be 0.7-4.0ppm, while H2S and VOCs levels were not detectable. During the collection, the inspectors described a pungent, sulfuric odor. CITIZEN COMPLAINT (T111853)- Ms. Debra Ramirez stated concern over the Conoco Phillips discharge. The LDEQ inspector's observations stated that the release was caused by a malfunction of the net gas compressor in the No. 10 reformer, which relieves to the North Flare. In an attempt to mitigate the release, operations began cutting charge rates to the units and diverting vent streams from the North Flare to the South Flare system. |
