TYLER, TX (KLTV) - The Texas Commission on Environmental Quality is investigating after an incident at the Delek Refinery in Tyler on Thursday.
The incident, is classified as an 'upset event' by the TCEQ, meaning it was not a planned event or part of the normal operations of the facility.
Smoke and flames could be seen for miles during the incident. Company officials filed a report with the TCEQ describing the incident occurred after a power interruption that led to excess emissions.
The situation was brought under control by Noon Thursday. The Fluid Catalytic Cracking Unit was temporarily shut down. The plant is reported to be back in full operation.
The Texas Commission on Environmental Quality is investigating and reports will be reviewed.
TCEQ requires facilities to report emissions that exceed the permitted values. The Delek Refinery has had dozens of those reports filed nearly every year. So far in 2014, four reports have been filed by Delek. Agency officials said the reports could come from a variety of scenarios from a burnoff to a spill or several other problems.
TCEQ investigators said they will compare their numbers with the company's numbers to make sure the facility stayed within permitted levels.
