DOW JONES NEWSWIRES The following table lists unplanned and planned production outages at U.S. refineries as reported by Dow Jones Newswires. The information is compiled from both official and unofficial refining sources and doesn't purport to be a comprehensive list. Chevron Corp. (CVX) reported an upset April 11 at the sulfur recovery unit at its refinery in El Segundo, Calif., according to a government filing. Valero Energy Corp. (VLO) on April 10 said its oil refinery in Meraux, La., is in restart mode following a brief power outage earlier in the day. The alkylation unit will remain shut for turnaround maintenance and the FCCU will be off line until the alkylation unit returns to service. Planned turnaround maintenance under way since early March continues at Valero Energy Corp.'s (VLO) Memphis refinery crude distillation unit. The plant filed a report to NRC in anticipation of possible flaring or emissions as the crude unit at Memphis, and other units, begin the restart process following the turnaround, however the crude unit turnaround is still under way, the company said on April 10. Planned crude, coker and reformer maintenance has concluded at ConocoPhillips' San Francisco-area refinery in Rodeo, California, company spokesman Rich Johnson said on April 9. Traders doing business in the region said the work well underway in early March; published reports said the turnaround began in mid-Feb. 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. No other details were provided. HollyFrontier Corp. (HFC) on April 5 said an FCCU at its Navajo refinery in Artesia, New Mexico cracking unit will be shut down for 10 to 15 days for unscheduled mechanical repairs.

(XOM) on April 4 confirmed the shutdown of Crude Unit B, a coker unit and corresponding units for several weeks of planned maintenance at it's refinery in Beaumont, Texas.
