The Birmingham office of the FBI has said a suspicious package found on a railcar at Daikin’s Decatur facility is not explosive but actually contained marijuana.

The FBI tweeted the information just moments ago.

Hartselle and Morgan County were monitoring a situation after a suspicious device was found attached to a rail car at the Daikin facility on Alabama 20 in Decatur. The railcar contains hazardous material.

According to an email from Decatur Police Public Information John Crouch, the department took the threat seriously because the rail car is contained hydrogen fluoride.

Alabama 20 was closed from Alabama 67 to the Lawrence County line. The U.S. Coast Guard also closed the Tennessee River from Mallard Fox Industrial Park to the U.S. 31 bridge.

Hartselle Police Public Information Officer Lt. Justin Barley said they were contacted by the Morgan County Emergency Management Agency about the incident, but no evacuations have been ordered at this time.

“We are on standby at this time,” Barley said earlier in the day.

Morgan County Schools dismissed school as a precaution West Morgan Elementary, West Morgan Middle and West Morgan High School at 10:30.  Any students remaining at school at 10:45 will be evacuated to Danville High School children can be checked out at the gymnasium.  Please take necessary actions to insure the safety of your children.
