Accident Classified As: Reportable Quantity
The release resulted from a leak caused by a loose flange.
The release was caused by an unanticipated flange leak.
A pan was placed under the leaking flange to collect oil for reprocessing, and to mitigate further release of the material to soil. The bolts were replaced and tightened which stopped the leak. The contaminated soil was remediated immediately after the leak was isolated. 1.5 barrels of Coker feed (or 63 gallons) was also spilt to soil but is not reported as a specific pollutant emitted. However, coker feed has the same RQ as crude oil (1 barrel or 42 gallons) and is thus exceeded. The RQ for PAHs was also exceeded.
