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.

Valero Energy Corp. (VLO) reported on Dec. 22 a power disruption at its 170,000 barrel-a-day McKee refinery in Texas. Supply was not impacted, a Valero spokemsman said.

Alon USA Energy (AJL) said on Dec. 21 that maintenance being performed at its refinery in Big Spring, Texas, would not impact production.

Chevron Corp. (CVX) took a hydrotreater offline at its refinery in Richmond, Calif., on Dec. 20, sources said. The unit was brought back online before the end of the day, the sources added.

Sunoco Inc. (SUN) took down a hydrotreater unit at its 335,000 barrel-a-day refinery in Philadelphia, Penn., for maintenance, a person familiar with the refinery said on Dec. 15. It was unknown how long the unit would be offline.

Western Refining Inc. (WNR) said Dec. 15 that the diesel hydrotreater at its 128,000-barrel-a-day refinery in El Paso, Texas, shut down unexpectedly.

ConocoPhillips (COP) said Dec. 14 that it will conduct maintenance until Dec. 20 on the electrostatic precipitators at its refinery in Borger, Texas, which will effect the fluid catalyst convertor unit, according to the company's filing with the Texas Commission on Environmental Quality.

Pasadena Refining's Texas coker unit fire on Dec. 10 injures one man. The fire was contained and no other units at the plant were impacted, a company spokesman said.

ConocoPhillips (COP) said a process unit upset and coke drum fire occurred at its Wood River refinery in Roxana, Illinois, on Dec. 9, a filing to Illinois state environmental regulators said.

ConocoPhillips on Dec. 9 said excess opacity was released at its Sweeny, Texas, refinery; the cause of the event wasn't specified. Conoco spokesman Rich Johnson confirmed there is planned maintenance work under way at the refinery, but didn't comment on the specific units involved and the duration of the work.
