Cogeneration unit
Cause: On February 7, 2013, ExxonMobil experienced an uncontrolled leak of carbon monoxide for three minutes from a cogeneration unit. At the time of the incident, the facility was unable to determine the amount of the release, but wanted to report within one hour in the event the CO permit was exceeded. The release was caused by the malfunction of a control on the cogeneration unit, which developed a decrease in operating rate and insufficient combustion. The malfunction occurred while the turbines were being cleaned of carbon deposits. A written notification dated February 14, 2013, was received by LDEQ from the facility, which indicated that after further evaluation, no reportable quantities were exceeded.

Followup: No



No Information Given
Cause: Intermittent hydrocarbon flaring is expected to occur through the month of September 2014 due to planned unit shut-down and start-up. All emissions are permitted.
