Narrative
On august 10, 2014 at approximately 18:45 cdt a terminal gauger discovered oil on the ground beneath the tank 64 mixer motor. The clearbrook terminal supervisor was notified and arrived on site about a half hour later. The mixer was not actively leaking at the time of discovery, but oil had absorbed into the surrounding soil. On monday august 11th, oil recovery and removal of contaminated soil commenced, and once tank 64 was pumped down, the mixers mechanical seal was removed for inspection and a replacement installed. Upon examination of the seal, it was found to have excessive sediment buildup between the primary face of the mechanical seal and the rubber o-ring, which allowed oil to leak through the seal and run out of the unplugged weep hole in the shaft housing. Approximately 7 cubic yards of contaminated soil has been taken to an approved disposal facility.
