Narrative
On 11/3/18 at approx. 4:45am while performing station rounds the operator found mixer on tank 3501 leaking crude oil from gearbox / seal area. Approx. 20 gallons of crude oil was released on the ground, with no impact offsite or to waterways. It was determined that the thrust bearing inside the gearbox failed causing the gearbox seal to fail. The mixer was isolated and the gearbox was replaced. To prevent reoccurrence, we will be inspecting tank gearboxes on a quarterly basis.
