About 400 people were allowed to return to their homes in Bladenboro Saturday night after it was determined the tank car was secure and there was no immediate threat of dangerous fumes being released.
The car was one of 10 that derailed Saturday as a CSX freight train passed through town. Officials from the railroad and Bladen County decided to offload the chemical before trying to move the car later this week.
"Hazmat has deemed there is no leak at this time however CSX wants to go ahead, due to the way the tanker is positioned they want to off load the ammonia which is going to be a time consuming process," sheriff's Capt. Rodney Hester told WTVD-TV, Raleigh, N.C.
