Hundreds of people forced out of their homes and businesses in East Palestine are hoping a media briefing set for Tuesday afternoon will provide more information about when things will return to normal.

Authorities will provide a media update at 1 p.m. Tuesday at the East Palestine Elementary School Gymnasium located at 195 West Grant Street. 

Deputy Columbiana County EMA Director Brian Rutledge told 21 News earlier in the day that aircraft have been flying over the village so experts from the Ohio and U.S. EPA could monitor air and water quality levels following Monday’s controlled burn of chemicals in rail tankers that derailed in the village on Friday.

Rutledge says authorities have been responding to complaints or concerns about odors and haze from East Liverpool to Trumbull County.

It’s not known when the "all clear" will be issued so people in the evacuation area can return to their homes and businesses can open again.

When it’s determined that the situation is stable and safe, Norfolk and Southern Railroad crews will start removing wrecked tankers.
