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

Cause: The plant experienced a pipe leak in the OMNI 143A unit. The pipe integrity had been compromised during certain operating conditions of the unit that occur on an infrequent basis. These operating conditions are called catalyst burn downs. The pipe leak most likely developed during previous catalyst burn downs.

Followup: No

Notes: The unit was immediately shutdown to stop the leak. Water was also applied to the leak in order to minimize the emissions. The entire segment of the pipe that the leak occurred on was replaced with Teflon lined pipe in order to improve the integrity and prevent any future incidents.

113 unit
Cause: The release was the result of a fugitive gasket leak at the man way to the HF recycle Hold Tank in the 113 unit (Trichlorofluoroethane unit). The unit was in the process of startup and the hold tank was empty and had just started to receive flow.

Followup: No

Notes: The flow was blocked in, the unit was shutdown, and the insulation was removed. The gasket was replaced and the flange bolts retightened. No further leak upon restart of the unit. Citizen complaints were reporting an odor described as sulfur or burnt match odor.
