A relative of Cuevas filed a multimillion-dollar wrongful death and injury lawsuit against San Antonio-based Valero in April. The suit claims that there was a failure to ensure that there were no hazardous or flammable gases in a flare line and there was a failure to provide timely firefighting assistance.
Cooke said at the time that the fire was extinguished before firefighters arrived.
A Tennessee Occupational Safety and Health Administration inspection done after the fire cited the plant for nine serious violations and fined it $63,000.
The violations were related to the process of safety management of highly hazardous chemicals and control of hazardous energy, according to the inspection report.
