Narrative
On december 1st work began on connecting a newly constructed tank to an existing pump and pipeline system. At the end of the work day the final set of flanges to the pump were lined up and studs and nuts were installed, there was some additional work that still needed to be completed to align the pump so these flanges were to be completed the following day.. During the night as the level of the tank rose, the limits on the mov on shell valve on the tank were not set correctly and the valve was not fully seated. As the tank level rose the shell valve began to leak by filling the newly constructed suction piping. When the crude in the new suction line filled to the point of the un-tightened flanges it began to leak into the pump containment. Based on tank gauges and site evaluation, it was determined that 33 barrels of crude was release on and around the pump pad. All free crude was removed from site with a vacuum truck and 2 loads of contaminate soil was removed and will be disposed of properly.
