LDEQ Accident Number
Accident Date
Point Source(s) Notes Amount of Release

Cause: External corrosion

Followup: No

Notes: clamps were installed to stop leak and blinds were installed at upstream block valves to completely isolate lines
88.0 gallons

Underground line
Cause: Leak in underground line of finished diesel.

Followup: No

Notes: This release is reportable quantity. Refinery letter states that reportable quantities were exceeded for oil to soil. Excavated to find source of leak, clamped line, Vacuum trucks were used to remove oil from the ground, and full site remediation will be completed. Spill was contained on-site.
226.8 gallons

No Information Given
Cause: Fire training was held at the fire training grounds, and the chemicals involved was Diesel and compressed Natural gas. Smoke was released into the air.

Followup: No

Notes: No Information was given for remedial actions. Planned procedure for fire training. Training occurred on two separate days, the 2nd and the 3rd.

no information given
Cause: Underground line leaked diesel fuel and exceeded RQ.

Followup: No

Notes: A clamp was placed on line to prevent further leaking, spill vacuumed, and contaminated soil removed. 4 barrels of diesel released which is above the RQ value.
168.0 gallons

Cause: A diesel oil spill. An eight inch pipe ruptured releasing approximately 25 barrels of diesel impacting soil. Report states that spill was contained on-site.

Followup: No

Notes: RQ. Letter states that a clamp was installed on the ruptured pipe, and the pipe was de-inventoried to prevent further release. Vacuum trucks removed oil from nearby sewers and diesel impacted soil was excavated for disposal. No injuries, fires or road closures were reported as a result of this incident.
1,050.0 gallons

No information given
Cause: ExxonMobil Baton Rouge Refinery wrote a letter to the LDEQ as notification of the events and circumstances surrounding the oil spill that occurred at the facility on August 25, 2011. Due to prompt incident response to mitigate the event duration, no reportable quantities were exceeded. Approximately 15 gallons of diesel were released. There were no complaints, injuries, or offsite impact as a result of this incident. Soil remediation is underway.

Followup: No

Notes: Soil remediation is underway.
15.0 gallons

Cooling tower 39
Cause: Notification was given that there was a potential leak at cooling tower 40. Diesel was seen in sample results without physical signs. It was later determined that the sample result for cooling tower 39 was erroneously reported as being from cooling tower 40. Cooling tower 39 was already reported as having a leak.

Followup: No

Notes: No remedial actions reported. Exxon Refinery found exchangers that might be the source of the tower 39 leak and fixed those. The facility also took a new sample and the TOC levels are now normal. Cooling tower 39 has previously been reported as having a leak, as discovered during routine sampling using El Paso method (LSP incident #11-03335 and 11-03511) and all emissions from it will be reported under those incident numbers.

Tank #134
Cause: Cycle oil was leaking from the bottom of Tank #134 and into the soil.

Followup: No

Notes: The oil was pumped into another tank.
26.0 gallons

Cause: An oil spill occurred at the ExxonMobil Baton Rouge Refinery on February 26, 2013. Approximately 1.5 barrels of diesel was released to the soil due to improper equipment preparation. Reportable quantities were exceeded.

Followup: No

Notes: At the time of the spill the weather conditions were as follows: 51 degrees Fahrenheit, 16 mph winds from the West and no precipitation. Upon discovery, mitigation measures were initiated; soil remediation was completed on March 1, 2013. The line was isolated within five minutes of discovery.
63.0 gallons
No LDEQ Reported

Cause: Oil sheen discovered in Callahan Bayou at the ExxonMobil Baton Rouge Refinery on January 15, 2013. The current LPDES permit, effective October 2012 (LA0005584, Part1, Page 5 of 5) states "There shall be no visible sheen or stain attributable to this discharge in the drainage area downstream from the permitted outfall. The drainage area downstream is defined as the area in the outfall canal located downstream of any control device, prior to entering the main channel of the Mississippi River."

Followup: Yes

Notes: All material was contained within the last containment boom prior entering into the Mississippi River. After further evaluation, we have determined that no reportable quantities were exceeded. Approximately 1 pint of diesel was release into Callahan Bayou.
0.1 gallons
