A fire broke out at a diesel hydrotreater, with the unit suffering severe damage, according to people familiar with the incident. The fire was near the plant's fluid catalytic cracker, and part of the refinery has been shut down, according to the people, who said a decision hasn't yet been made whether to shut the entire plant.
A few minor injuries were reported, according to people familiar. A Valero spokesperson said all personnel have been accounted for. Local officials have shut two nearby state highways as a precaution, the spokesperson said.
