Cause of Problem: Equipment Failure

On January 30, 2014, at approximately 06:30, Chalmette Refining personnel identified an atmospheric Process Safety Valve (PSV) leaking on the Crude #1 stabilizer tower, resulting in a release of a liquid petroleum gas (LPG) material comprised primarily of propane and butane.

Discharge Preventable - Under Investigation

Results from PSV analysis will be provided in 60 day follow up letter.

Notes/Remedial Actions

The issue was safely resolved at 07:15 am by blocking the inlet to the relief valve. The PSV on the Crude #1 stabilizer tower was sent our for evaluation and it was determined that the internal spring had fractured causing the malfunction. A failure analysis of the PSV is being conducted to determine the cause of the failure and prevent recurrence. 60 day follow up is promised but has not been available to LABB.
