Authorities on Monday night ended a shelter-in-place order for more than 90,000 people east of Atlanta following a weekend chemical plant fire that sent a massive plume of dark smoke into the Georgia sky and led to complaints about a strong chemical smell and haze.

People in the northern part of Rockdale County were ordered to evacuate and others were told to shelter in place with windows and doors closed.

A massive explosion at a chemical plant in Georgia caused a huge plume of smoke, and authorities have instructed residents and businesses to shelter in place.
