Updated post regarding the Hazmat incident on June 17th.
The City of Newton Fire Department received a fire alarm on Wednesday June 17th, reporting a sulfur dioxide leak at the Newton wastewater treatment plant located on Mackay Road.
Following preliminary verification by on-site professional personnel, the actual leaked substance was confirmed to be chlorine gas leaking to the atmosphere. Newton Fire Battalion 1 requested Catawba County Hazmat team, Catawba County Emergency management as well as Conover Fire Department.
Catawba County Hazmat entered the incident hot zone wearing Level A Hazmat suits. Crews located the leak source as a 1-ton capacity chlorine cylinder. After the first response team successfully completed leak stoppage work and evacuated the area in an orderly manner, a second team entered the site to conduct ventilation and air exchange, as well as continuous atmospheric monitoring.
After multiple rounds of comprehensive testing, it was confirmed that neither the
incident zone nor surrounding areas presented any Immediately Dangerous to Life or Health (IDLH) risk conditions. The site was formally handed back to the plant management to resume operations.
No emergency responders, plant staff, or members of the surrounding public sustained injuries throughout the entire incident, and no safety threats were posed to residents.
The cause of the leak has been determined to be a mechanical failure during a power interruption to the facility.
The smooth resolution of this incident was made possible by the regional mutual aid mechanism and routine professional training.
