Cause: On July 22, 2012 GO-1 operators were in the process of draining the water layer from a tank to the oil water separator. During this process the tank level got low enough to allow a fuel oil layer to drain from the tank into the main conveyance system. This caused a release of benzene.

Followup: Yes

Notes: The fuel oil was recovered and the system returned to normal. No reportable quantities were exceeded. The report was submitted more than 7 days after the incident and verbal notification.
