Releases of Crude Oil

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

Bulkhead at B-Dock
Cause: Sheen observed (hydrocarbon release) from B-Dock; potentially released when area was inundated of the area during Hurricane Rita. Release of crude oil from C-Dock; during Hurricane Rita a nipple located on a crude oil loading arm was broken off.


Notes: Area was boomed off and crude oil material recovered. Offsite impact. Miller Environmental responded for the clean up. Crude oil approximately one foot thick. Tank either ovrflowed or line valve breach. Had small natural gas leak from inlet piping blowing.

B-7 Flare 3(IX)33 ; Sulften absorber vent at Sulfur Recovery Unit 3(XX-H)1 ; TGII Absorber Vent at Sulfur Recovery Unit 3(XX-J)5 ; furnaces and boilers ; sweet crude oil pipeline to Tank 101
Cause: short duration rain event; swirling winds 60mph+, hail and lightning - see notes - see not

Followup: Yes

Notes: The storm caused a loss of power at Substation 21 and power blips on lines from Entergy impacting the Sulfur Recovery Plant. CITGO believes water entered the Substation via a the joint b/w the roof and the side wall causing a fused switch failure. Loss of power resulted in higher pressure and increase in liquid levels causing flaring at B-7. Loss of amine flow and hydrogen sulfide absorption generated heavy smoking from some of the boiler stacks and upset the Sulfur Recovery Plant. Operations pnnel inadvertently overloaded the Central Amine Unit causing high SO2 emissions throughout the Refinery. The crude oil leak was caused by internal corrosion. Limited offsite impact from soot from smoking boilers. REMEDIAL ACTIONS --> A Root Cau

16" pipe near Tank 50
Cause: LDEQ report states "...an overhead 16" pipe near Tank 50 developed a pinhole leak in the north tank farm pipe rack area. The leak appeared to be from corrosion." It leaked less than 18 gallons of crude oil, which is BRQ.

Followup: No

Notes: BRQ. No reportable quantities were exceeded. LDEQ states that "the free oil was picked up with a vacuum truck and the contaminated soil was excavated and disposed of."

Cause: During transfer operations, crude oil was released to the ground. The release was due to the mechanical failure of the crude oil transfer pump.

Followup: No

Notes: The transfer operations were shutdown. The soil remediation by vacuum truck and excavation began. The repairs to the crude oil transfer pump have been completed. 3.6 barrels was listed and converted to 151.2 gallons. Accident listed as "NA," but oil released did exceed reportable quantity.
151.2 gallons

Crude Line Flange
Cause: The Oil Movement B - A Topper crude line flange was discovered to be leaking crude oil to the ground due to cold weather induced mechanical failure. There was no off site impact. IN POLICE REPORT: "... A flange had loose bolts...flange has been tightened to stop the leak"

Followup: No

Notes: Oil Movement B - A crude line flange was repaired Cold weather would make it harder for nut/bolt to become unscrewed and cause a leak because the metal compresses slightly in the colder temperatures.
