|LDEQ Accident Number
|Point Source(s)||Notes||Amount of Release|
|Receiving Tank||Cause: Contract personnel were performing a transfer or diesel fuel from storage, into a fueling truck to be used to move diesel equipment being used within the refinery. The responsible person left the transfer and when he returned, found that the receiving tank had overflowed.|
Notes: The event began on 10/21/05 at approximately 1320 hours. At approximately 0510 hours on 10/21/05, refinery contract personnel identified a spill of diesel to an asphalt roadway and adjacent drainage ditch on the refinery property. The area was located within the refinery, along a service road in the East Tank Farm, running parallel to Saint Bernard Highway. Contract personnel were performing a transfer of diesel fuel from storage, into a fueling truck to be used to move diesel to equipment being used within the refinery. The responsible person left the transfer and when he returned, found that the receiving tank had overflowed. Personnel estimated that approximately 55 gallons of diesel had spilled. This incident did not cause an Emergency Condition. Liquid recovered was returned to refinery slop oil for processing. Excavated soils were containerized and staged on side pending proper disposal at an off site disposal facility. When the situation was discovered, the transfer was stopped immediately, ending the incident. The person directly responsible for the fuel transfer was disciplined by his employer. Personnel responsible for the transfer of fuels for an onsite consumption have been coach regarding importance of spill prevention and following proper procedures. Liquid released was contained on refinery property and recovered via vacuum truck. No migration off of refinery property or to groundwater has been observed.
|No information given||Cause: Diesel Fuel was released to the surface of the Mississippi River|
Notes: BELOW REPORTABLE QUANTITIES. No information given.
|No LDEQ Reported|
|C8901 - meter station sump vessel||Cause: Sump vent overfilled due to a failed check valve which allowed pressure from the discharge pump on a common discharge pipe to back pressure in sump vent C8901|
Notes: BELOW REPORTABLE QUANTITIES. All draining and pumping of vessels on the Dock 2 meter platform was stopped. Personnel attempted to capture the overflow with buckets. Hard boom was deployed in order to capture the sheen. Absorbent materials were used in order to clean up the sheen and residual diesel.
|Refinery dock #4 transfer line||Cause: Drip from the transfer line on Refinery Dock #4 caused a release of diesel fuel to the surface of the Mississippi River.|
Notes: Absorbent materials placed under the drip to contain the material; a boom was used to contain and absorb the sheen on the water surface; vacuum trucks were also used. Note: a subsequent letter from the same day rescinds the report. See below.
Bleeder valve plug in truck loading rack area
|Cause: a bleeder valve failed on a line leading to the truck loading facility|
Notes: DEQ report with no corresponding letter from CRLLC. Valve was quickly isolated and replaced. Liquid was recovered via vacuum.
|LGO line||Cause: diesel leak from piping on the Coker Light Gas Oil line. Overpressuring in piping caused components to loosen|
Notes: Line was isolated to stop leak. Vacuum truck recovered released liquids. Training on the interaction of two hot streams with an ambient temperature stream in a common pipe was discussed with the operators
|Tank 6308||Cause: transfer was not shut down as scheduled so tank 6308 overflowed during diesel transfer from Tank 408|
Notes: Released liquids were recovered via vacuum truck for reprocessing. Onsite impacted soil is being excavated and containerized for disposal. Additional mitigation steps will be implemented during tank-to-tank transfers at the refinery. Specific actions are currently being developed as part of the investigation.
|No information given||Cause: pump seal failed on G8111 at the #2 Coker causing a fire|
Notes: Letter states that emissions were BRQ.
|Underground pipe near Tank 1004||Cause: "Approximately 4.7 barrels of diesel leaked from an above grade pipe, near facility Tank 1004, that had been buried. The leak was the result of external corrosion in the pipe.|
Notes: RQ. A vacuum truck was used to recover gallons of diesel, and approximately cubic yards of contaminated earth were removed. The contaminated earth was disposed of at landfill. Repairs to the pipe were completed on 6/17/10 when a new section of pipe was re-routed.
|tubing at tank #33||Cause: tubing leaking at tank #33|
Notes: no information given
|Cause: ON Friday, May 31 2013, at approximately 1118 hours, Chalmette Refinery L.L.C (CRLLC) personnel observed a small visible sheen at the Number Four Dock due to a leak in the fuel supply line to the Once Through Cooling Water (OTCW) pump. Immediate notifications were made to the appropriate agencies and US Environmental deployed containment and absorbent boom to contain and collect sheen. An investigation determined that the source of the leak was from a hole in the suppy hose. The leak was immediately isolated at 1125 hours. No emergency conditions resulted from this release.|
Notes: Immediate notifications were made to the appropriate agencies and US Environmental deployed containment and absorbent boom to contain and collect the sheen. Additional shields will be installed around the supply hose area for the supply pumps to provide an additional barrier preventing diesel from escaping the containment area.
|No LDEQ Reported|
|crude terminal dock||Cause: On Friday, March 14, 2014, at approximately 1707 hours, Chalmette Refinery personnel observed a small visible sheen at the crude terminal dock from utility pump G-2907. A small leak developed on G-2907 and was leaking into the containment area beneath the pump. A small hole had developed in the containment area allowing a small amount of diesel to leak into the river.|
Notes: After isolating the leak operators used absorbent pads to remove hydrocarbons from the pan and deployed initial containment boom into the river. USES were utilized to clean the affected decking and pilings, collected the sheen, and removed the boom. The catch pan below G-2907 will be repaired or replaced.
|Tank farm, Tank 405||Cause: On Sunday, February 16, 2014 at approximately 16:30 hours, unit operator identified a spill of ultra low sulfur diesel (ULSD) in the vicinity of Tank 405 at the sump. The operator obtained the proper protective equipment and at approximately 17:30 hours identified the spill to be beyond the sump area. All contents were fully contained within the tank dyke area. Air monitoring was conducted in the area add lower explosive limit (LEL) readings were all non-detect. An investigation to determine the root cause analysis is ongoing and results will be provided in a 60-day follow up report.|
Notes: Upon discovery, notifications were made to shift supervision and the area was barricaded off to restrict access. The appropriate agencies were notified and crews were mobilized to commence clean-up activities. The root cause of the spill is under investigation. Based on the results of the investigation, measures to minimize the likelihood of recurrence will be identified and implemented as appropriate.
