ALICEVILLE, Ala. (AP) - Dark oil still pollutes an Alabama swamp four months after a tanker train derailed there, and industry critics say it's an example of the danger of transporting huge amounts of crude by rail.
The isolated wetland near Aliceville, Ala., smelled like a garage when a reporter from The Associated Press visited last week.
A representative of the environmental group Waterkeeper Alliance says the railroad and government regulators failed to remove all the oil before rebuilding damaged track and reopening it to trains.
The Environmental Protection Agency says officials are still working on containing spilled oil and cleaning it up.
Questions about the Alabama cleanup come as the National Transportation Safety Board considers tighter rules for the rail transportation of Bakken oil from booming shale oilfields in North Dakota and Montana.
