There was a power outage at about 7 a.m. today at the Valero Port Arthur Refinery with a subsequent fire in a heater at a diesel hydrotreater unit. The fire was quickly contained, and Valero officials immediately notified all appropriate regulatory agencies. All Valero employees are accounted for and there were no reports of employee injuries, although there is a report of a contractor being transported to a local hospital due to anxiety. Power was out in some areas of the plant but most process units are in operation. Valero emergency response officials have monitored air quality and there are no indications of any concerns to the community.
