121512

2010-02-13
flare gas recovery unit
Cause: tie-in line being under construction in new Flare Gas Recovery Unit spilled hydrostatic test water and residual light cat feed from the blinded end of a pipe--initial estimate is 420gal total. Written report states that release was BRQ.

Followup: No

Notes: BRQ. Written report states that calculations determined the release was below reportable quantities. Majority of spill cleared with vacuum truck and absorbent pads. LDEQ conducted on-site visit and report on 2/13/10.

2011-08-24
Fluidized Catalytic Cracking Units (FCCU) stacks; Wet Gas Scrubber
Cause: Hydrogen Cyanide and Chlorine were identified in the Fluidized Catalytic Cracking units vent stacks during stack testing mandated by the EPA's information collection request. This has been a continuous and on-going release

Followup: Yes

Notes: CITGO's review of the stack testing and operating data indicates that an air release of hydrogen cyanide and chlorine exceeded a reportable quantity although no quantities were indicated in the report. CITGO was required by EPA to conduct stack testing on 1 of its 3 Fluidized Catalytic Cracking units and report such stack test results before August 31, 2011 to the EPA. The ICR required that CITGO test for hydrogen cyanide and chlorine from this unit. 30 day letter submitted on September 21, 2011 and 1 year follow-up submitted August 24, 2012. CITGO has been releasing between 1,155 lbs to 5,535 lbs of hydrogen cyanide a day for a total of 846,479 lbs per year. They have also been releasing 88 lbs to 116 lbs per day of chlorine for a total of 34,111 lbs per day.
Hydrogen Cyanide: 846,479.0 pounds
Chlorine Gas: 34,111.0 pounds

Tank 182
Cause: On July 7 at approximately 9:35 PM, a blowdown of the girbotol unit to Tank 182 caused a release of propane (C3 mix) to the air from Tank 182.

Followup: Yes

Notes: System was secured after discovery of release. No specific information given on remedial actions. A review of operating data from event showed no RQs exceeded.

2013-05-09
No information Given
Cause: On May 9, 2013, CITGO Petroleum Complex notified LDEQ's Single Point of Contact of a flammable gas (propane) release during maintenance on a pilot gas for a flare. Purge gas was used to keep the flare lit. As a result of high winds, the pilot light went out and approximately 2800 lbs of gas was released to the atmosphere. The amount released was below the reportable quantity; therefore CITGO is regarding this as a courtesy call.

Followup: No

Transfer Line
Cause: During maintenance activities of a transfer line, Reformate was spilled to the ground outside of containment. The transfer line was being drained from a line break at a flange. When the line break at the flange was made, a rapid release of Reformate overcame the secondary containment. No off site impacts due to this spill. Reformate is a mixture >/= 80% Naphtha, 10%-<35% Toluene, <1% Benzene

Followup: Yes

Notes: The transfer line flange was re-bolted to stop the release. Pressure gauges were installed on the transfer line to prevent a rapid release of Reformate while daining the line during the maintenance activity.
Reformate: 273.0 gallons
