NEW ORLEANS - A jury has been chosen for the trial of a former BP rig supervisor who faces a pollution charge in the 2010 Deepwater Horizon disaster in the Gulf of Mexico.

U.S. District Judge Stanwood Duval has scheduled opening arguments Wednesday in Robert Kaluza's trial.

Kaluza faces a misdemeanor charge of violating the Clean Water Act. Prosecutors say he and another rig supervisor, Donald Vidrine, missed clear signs of trouble before the well blowout.

Vidrine pleaded guilty to the misdemeanor pollution charge last year. Both men had faced charges of manslaughter after 11 workers were killed when the offshore rig exploded, but federal prosecutors backed off those charges.
