Accident Classified As: Reportable Quantity
Cause of Problem: Human Factors
During a review of trends on control equipment on 1/8/2014 it was noticed that Placid's internal vapor combustor (source ID 1-91, EQT 0041) was not operating. The combuster has the ability to control emissions from barge and/or truck loading from Placid's Tank Farm, however only Placid's Tank Farm was routed to the combustor during the outage. Placid has no known reason why the combustor failed other than abnormally cold weather. Placid has assessed the root cause as operator error as the shutdown alarm was not acknowledged.
Discharge Preventable - No
Placid states that this incident was the result of mechanical failure and therefore not foreseeable. However, earlier in the report Placid indicates the discharge was a result of operator factors as they operator did not acknowledge the shutdown alarm.
