Planned turnaround maintenance under way since early March continues at Valero Energy Corp.'s (VLO) Memphis refinery crude distillation unit.

The Wood River Refinery, a joint venture owned by ConocoPhillips (COP) and Cenovus Energy (CVE), in Roxana, Illinois, said emissions of sulfur dioxide were routed to the plant's safety flare stack on Saturday evening after an ultralow-sulfur diesel hydrotreater had tripped off line.
