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.

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. HollyFrontier said the downtime will reduce crude throughput by approximately 800,000 barrels.

BP PLC (BP) on April 5 said about eight hours of routine maintenance started at FCCU No. 1's electrostatic precipitator at its Texas City, Texas, refinery at around 10:30 a.m. CDT. Maintenance continues at the plant's FCCU No. 3 and an alkylation unit, a person familiar with operations at the refinery said.

ExxonMobil Corp. (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. Minimal impact to production is expected and all contractual commitments will be met, the company said.

Pasadena Refining Systems, Inc. (PRSI) on April 4 said an FCCU at its Pasadena, Texas, oil refinery had returned to service after a power failure the day before. The unit was restarted as quickly as possible after shutting down at around 2 p.m. CDT on April 3.

ConocoPhillips (COP) on April 2 reported excess emissions that resulted in flaring at its San Francisco-area oil refinery in Rodeo, Calif. The notification to the California Emergency Management Agency didn't specify whether the flaring was planned, or perhaps associated with a restart of a process unit, or units, following turnaround maintenance that got under way March 5.

A power interruption at CVR Energy's (CVI) Wynnewood, Okla., refinery caused a sulfur recovery unit to trip off line on April 2, a filing to the NRC said. It isn't clear when power was restored or if the unit had been restarted. CVR doesn't comment on day-to-day operations.

Valero Energy Corp. (VLO) on April 2 said previously announced planned turnaround maintenance on a key gasoline-making fluid catalytic cracking unit at it's oil refinery in McKee, Texas, got under way over the weekend. The work is expected to take about five weeks to complete.

Planned flaring scheduled for April 3-6 at BP's (BP, BP.LN) Carson, Calif., refinery is the result of scheduled maintenance, a person familiar with the plant said on April 2.
