Authorities have raised their estimate of the amount of dangerous material improperly stored at an explosive recycling company in Louisiana.
Louisiana state police now believe 10 million pounds of a military propellant called M6 was improperly stored at Explo Systems near Doyline.
They originally believed it was only 6 million pounds that was recovered. Doyline was evacuated for a week in December over concerns a chain-reaction blast was possible.
Most of the M6 was moved into bunkers, but authorities are still looking for space to house 3.5 million pounds of material.
