Tank 83 was in the process of being pumped out to facilitate a product change from sweet to sour. The roof legs were in the lower position which allowed the roof to hit the mixer impellar which caused the seal to fail releasing approximately two barrels of crude. The mixer was removed from the tank and a blind manway cover installed. Contaminated soil was remediated onsite.
