In the day following the derailment, CN said it would be conducting a controlled flaring of 11 cars that contain a residue amount of liquid petroleum gas.Canadian National, which operates the train in question, said flaring had been finished at the site where approximately 25 railcars derailed on Thursday.That substance was quickly contained and the evacuation order was lifted within hours, officials said, emphasizing there was no ongoing danger to the public.
"...There is no danger to public safety or to the environment..." the railroad said in a statement."It is required to eliminate any left over product and allow for the safe removal of the railcar. Out of an abundance of caution, CN will be monitoring air quality." CN said Sunday that clean-up and remediation at the site will continue"over the next few weeks." Crews will remove railcars, repave the road and refurbish the crossing, the railroad said.Feeling out of the loop? We'll catch you up on the Chicago news you need to know. Sign up for the weekly
