NORFOLK, Neb. -- Travelers on Highway 275 shouldn't be alarmed if they see a large presence of first responders at the Norfolk West Water Treatment Plant.

Many first responders from the city of Norfolk and surrounding communities are only there for an emergency drill.

The drill is meant to test the full-scale response, operations, and coordination of regional first-responding agencies in the Norfolk area and in the city itself.

The scenario will play as a chlorine leak at the treatment plant, due to an increased dosage of the chemical being put into Norfolk's water.

In a press release, Region 11 emergency manager Bobbi Risor said the drill was the perfect opportunity for first responders to get ready when a real hazmat incident takes place.

"This will be a good opportunity for the Norfolk Regional Hazmat Team to train along with other city officials and for the City of Norfolk to open its Emergency Operations Center," Risor said. "Mutual Aid towns first responders will also be asked to participate as well."

While the situation is only for practice, the Norfolk Fire Division asks residents to use caution when traveling in the area.
