|Drain valves||Cause: The drain valves on three flare drip legs were discovered open and were immediately closed. The drip legs were left open after the routine draining.|
Notes: Valves were closed. Citgo failed to notify LDEQ 24 hours after the accident and did not write a follow up letter within 7 days either. Report was not made until 22days after the incident occurred. LDEQ investigated the accident and found a permit violation. LDEQ then granted Citgo a permit modification authorization.

|Cause: The operator failed to manually reset the solenoid valve that controlled the level in the F-104 drum prior to restarting the JC-102 compressor. Based on the definition of control equipment inLAC 33:III.1 1 1, Citgo failed, in this incident, to diligently maintain control equipment in proper working order whenever emissions were being made.
That initial failure to reset the solenoid valve cause a string of upsets, which began with the central amine upset.|
Notes: Immediate corrective actions taken were removing excess hydrocarbon from the central amine unit, amine feed to the SRUs was reduced, and efforts were made to identify the hydrocarbon source. Citgo conducted an incident investigation, which outlines several actions to be taken. Additional letters from refinery regarding this incident: 8/18/11, 10/27/11
|Sulfur Dioxide: 2,354.0 pounds|
|Tank 36 (EQT0088) and Tank 37 (EQT0089)||Cause: The operator failed to manually close the naphtha valve after the switch to C-4 was made, ultimately causing a roof drain leak on Tank 37, a slop oil tank containing hydrogen sulfide. Thus, Citgo failed to diligently maintain control equipment in proper working order whenever emissions were being made.|
Notes: Immediate corrective actions taken were changing routings of materials into tank 37 and making efforts to identify the source of the light materials that were believed to cause the hydrocarbon release. Vacuum trucks were cleaning up the spill at the time of the police report.
|Volatile Organic Compounds (VOCs): 2,576.0 pounds|
Slop Oil: 2,016.0 gallons
|vacuum truck||Cause: According to the LDEQ report, the oil/water mix was spilled from a vacuum truck due to operator error.|
Notes: RQ: The spill was contained and cleaned up, and operators are being retrained on proper procedures to prevent recurrence. LDEQ and SPOC reports only. No Refinery Letter.

|LCMC A-Dock||Cause: On June 6, a mixture of water and diesel was spilled from the drip pan containment by a contractor to the Calcasieu River during maintanance activities on the CITGO Petroleum Corporation LCMC A-Dock creating a sheen.|
Notes: The maintenance activity was stopped and SPCC measure were taken to contain the sheen. To prevent reoccurrence, maintenance procedures are under review.
|Diesel Fuel: 0.1 gallons|
|B-dock||Cause: Initally Citgo reported a spill of a Xylene based material at the Citgo B-Dock. A Citgo representative stated that a contractor spilled approximately 7 gallons of Dupont Oil Red B Liquid Dye which is added to off road diesel fuel. The spill occurred on the dock during the loading of off road diesel onto a barge. Before the product could be recovered, a heavy rain occurred which caused the contamination trench to overflow resulting in the material entering the Calcasieu River. The material was contained by hard boom permanently in place at the dock area. The dye was recovered by placing sorbent boom and flushing. The recovery process took several months to accomplish. Sorbent boom was replaced periodically and disposed of in a land fill. Recovery of the dye was complete in May 2014.|
Notes: The spill was contained using SPCC measures and spill booms were deployed. The plugged containment trench was cleaned to prevent overflowing and the loading point for the red dye injection was relocated to an area better situated to contain spills. The report states there was no-off site damage yet admits to contaminating a major water source. The report also fails to give an end date, duration, or the amount of Xylene present with the dye. The clean up was finished sometime in May of 2014 according to the report. Citgo asked on four different occasions for extensions for the seven day letter which was finally reported on 05/20/2014. Citgo does not discuss why it took so long to file this report, though three additional letters were included with dates in February, March and April. Contaminant is ostensibly a proprietary mixture including xylene and other ingredients. The mixture is categorized as "not extremely hazardous, liquid."
