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

Cause: Placid Refining Company operates a flare gas recovery unit that recovers routinely generated gases that would have been otherwise flared in Source ID 18-74. The recovery unit was shut down due to turnaround related unit cleaning activities sending high concentrations of nitrogen and steam into the flare system. This control device bypass was not approved via a variance.

Followup: No

Notes: Report states that no RQ's were exceeded. On the other hand, it also says that mass emission permit limits for the flare were exceeded. Placid has requested a GCXVII activity be added to their permit to cover monthly preventative maintenance on the system but this will only cover 5 hours per month. Operations will notify environmental department prior to shutting down system in the future so it can be addressed properly with the agency prior to activity. Report says to see an attached calculation with the name and quantity of released pollutants. Report shows no sign of such calculation.
