On October 2, 2005, On-Scene Coordinator (OSC) Heath Smith responded to a report of a release of hazardous materials from the Daimler-Chrysler South Vehicle Production Facility (South Plant) in Fenton, Missouri. The release occurred when a steel/rubber expansion plug terminating a six-inch industrial wastewater line failed allowing industrial wastewater to flow into the facilities storm water runoff system and onto the Merrimac River.
