Accident Classified As: Below Reportable Quantity (BRQ)
Cause of Problem: Maintenance/Procedures
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.
