In a filing with state environmental regulators, the company said on Tuesday, Oct. 10, at about 9:00 pm local time, an upset occurred in Area 3. 
“Operations lost the ability to pump out the bottoms from the fractionator on the Delayed Coking Unit and the charge filters began to plug on the Hydrocracker Unit,” said the filing with the Texas Commission for Environmental Quality.
