Narrative
During the 0700 tank check, control center observed at 0720hrs that the tank level was dropping faster than it should have been with pumping activities. Notified the pipline technician and asked him to check on the tank at chico. Once tech arrived, he saw that the tank mixer had failed and crude oil was leaking out of the tank and there was a vapor cloud inside the dike. Tech contacted supervisor and the county sheriff and fire department was notified. Once unified command was set up, the fire department placed a foam blanket on the crude oil that was in the dike and crews started picking up product with vacuum trucks. Estimated volume lost is approximately 13,500 bbls, all crude was contained in the dike. We will determine the amount that was recovered. Environmental made all of the regulatory notifications. It was determined at the keeper ring on the hinge pin had failed. Notified the manufacture and was told that there had been problems with the ring failing and suggested a fix for the problem. All mixers with in the system have been checked and modiifications made on tank mixers to fix potential ring failures.
