Divers recovered one body after an oil rig explosion on the Gulf Coast. One person is still missing and 11 others are injured.

The Coast Guard responded to a may-day call Friday morning from a shallow-water production platform owned by Black Elk Energy.

Coast Guard Capt. Ed Cubanski told reporters in New Orleans the well was not producing at the time and no oil was leaking.

Cubanski said a small amount of oil spilled from the rig when workers using a torch cut into a 75-foot-long, 3-inch-wide line on the platform.

He also said a sheen one-half mile long and 200 yards wide was reported in the area.

"It's not going to be an uncontrolled discharge from everything we're getting right now," Cubanski said.

The federal government is sending a team of environmental enforcement inspectors to the scene to assess the environmental damage.

Plaquemines Parish spokeswoman Caitlin Campbell said the Coast Guard reported that the platform was intact and structurally sound.
