115023 2009-05-16	Platformer Debutanizer Trim Cooler, #1 Cooling Tower EQI: 61a-74	Cause: A high LEL was found at the #1 cooling tower, operations started checking for leaks and found that the debutanizer overhead trim cooler, 12-1309, was leaking hydrocarbons into the cooling water. Leak caused by under deposit corrosion. Followup: Yes Notes: The debutanizer trim cooler was isolated and leaking tubing plugged.	Methane: 0.9 pounds Ethane: 36.9 pounds Propane: 157.8 pounds Isobutane: 102.0 pounds n-Butane: 504.0 pounds 1-Pentene: 54.0 pounds n-Pentane: 28.0 pounds Volatile Organic Compounds: 1,779.5 pounds
No LDEQ Reported 2011-01-13	Line	Cause: Refinery letter states that corrosion on a three inch line under the dock resulted in pinhole leaks. OFFSITE: Material leaked into the Mississippi River.

152677 2013-12-04	Pipe leak at a pump in Unit 10 Crude unit	Cause: On December 4 at approximately 8:00 hours, there was a pinhole leak in 2 inch insulated piping. Corrosion caused the pinhole. Report states that none of the emitted pollutants are above reportable quantity levels. However, the RQ level for Flammable Liquids was exceeded during this event. Followup: No Notes: The unit was shut down to repair the leak as the piping could not be isolated. This piping will be routinely inspected and an upstream block valve was added to enable the isolation of this line. The material released was crude oil. It was entirely contained within the unit and routed to the Oily Water Sewer system.
