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.

A contract worker died Monday at Motiva's Port Arthur, Texas, refinery, a Shell spokeswoman said. The man was part of the Becon Construction Co. team working on the plant's crude processing expansion project; the cause of his death is under investigation. The Motiva refinery is a 50% joint venture between units of Royal Dutch Shell (RDSB, RDSA.LN) and Saudi Aramco.

Valero Energy Corp.'s (VLO) McKee refinery in Sunray, Texas, has yet to begin work on a key gasoline-making unit, which continues to operate at planned rates, a company spokesman said Monday. Over the weekend, the company reported that repairs would be performed on the casing for an expander at the fluid catalytic cracker, a gasoline-production unit, starting Sunday evening, according to a filing with state environmental regulators. The maintenance activity was expected to end this coming Saturday.

Several "planned flaring event" filings this week to California state environmental regulators are related to turnaround maintenance since March at Exxon Mobil's (XOM) oil refinery in Torrance, Calif., company spokeswoman Aarti Ramachandran said.

Tesoro Corp.'s (TSO) oil refinery in Mandan, N.D., was shutting down Friday so that 30 days of turnaround maintenance can get under way on Monday, said Benjamin Gress, an environmental scientist with the Air Quality Division of North Dakota's Department of Health. The company said the scheduled work is on schedule and will last through late May.
