101944 2007-12-28 | Point Source(s): Tank 37T 301 Pollutant(s):Oil - 0 gallons | Cause of Problem: Piping or Tubing A plugged drain line became unplugged allowing the wastewater to flow | DEQ report states that release was BRQ |
No LDEQ Number Available 2007-12-21 | Point Source(s): HGU WWTU Flare EPN 85D-105 Pollutant(s):Ammonia - BRQ | Cause of Problem: No Information Given see notes. Flame outage on flare causes release. | Under investigation - no remedial actions specified |
101702 2007-12-20 | Point Source(s): API Separator No. 2 Pollutant(s):Sludge - 840 pounds | Cause of Problem: Maintenance/Procedures AbClean, Inc was vacuuming sludge out of the API separator when some water broke free from the sludge and was sucked into the vacuum box. The vacuum box filled before AbClean could shut down the operation. Once the truck was shut off, the overfill proceeded back down the line and leaked out of the vacuum breaker onto the ground. | Approximately 2 barrels of dirty oil water/API sludge leaked onto the ground. All clean up activities completed on day of release. No further information given concerning remedial activities. Several measures were put into place to prevent a recurrence: (1) the vacuum box was moved to a level surface, (2) the vacuum hose (and vacuum breaker) was placed inside a concrete containment area, and (3) operations personnel were provided increased awareness and now check the level in the vacuum box at an increased frequency (i.e. every 10 minutes). |

100801 2007-11-06 | Point Source(s): Steam Boiler EPN 31F-810 Tail Gas Treatment Unit No. 4 Incinerator Stack EPN 78H-101 VPS-2 Atmospheric Tower Feed Heater EPN 83H-101 Pollutant(s):Nitrogen Oxide - 437 pounds Sulfur Dioxide - 3,694 pounds Sulfur Trioxide - 148 pounds Carbon Monoxide - 91 pounds Particulate Matter - 60 pounds Volatile Organic Compounds (VOCs) - 13 pounds Nitrous Oxide - 5 pounds Formaldehyde - 1 pounds Sour Diesel - 129,000 pounds | Cause of Problem: Seal or Gasket The seal on a diesel circulation pump on VPS-2 (a crude distillation unit) failed as a reslut of a suspected bearing problem. This seal failure caused the release of approximately 434 bbls of untreated (sour) diesel, which ignited, resulting in a fire. | Motiva has slowed down production throughout the refinery until investigations are complete. Inspected, repaired, and rebuilt the pump as necessary. W/r/t pump seal failure, rotating equipmt and other personnel will complete the investigation and implement necessary changes to monitoring, inspection, and maintenance procedures |
100454 2007-10-23 | Point Source(s): Fuel oil pump 70P-384 Pollutant(s):Fuel oil - 22 gallons Particulate Matter - 0 pounds Sulfur Dioxide - 0 pounds Nitrogen Dioxide - 0 pounds Carbon Monoxide - 0 pounds | Cause of Problem: Seal or Gasket While conducting evening rounds on the H-Oil unit, operations personnel noticed a fire on the seal of the fuel oil pump 70P-384. A leaking seal on the pump and high process temperatures resulted in the fire. | The pump was isolated from the process to cease fuel oil leakage. Approximately 22 gallons of fuel oil was released during the incident with 20 gallons being contained on the unit slab and the remainder being combusted. Operations personnel quickly responded with a fire extinguisher and extingushed the fire. Other operations personnel ceased operation of the pump and isolated it from the process. Motiva quickly activated the Emergency Response Plan. Motiva will continue to inspect pumps and associated process equipment during normal operational rounds for abnormal operation and for environmentally unfriendly and unsafe conditions. |
