On October 21, 2016, at approximately 8 a.m, a chemical release occurred at MGP Ingredients’ plant in Atchison, Kansas when an MGP employee working at the industrial pre-treatment facility inadvertently connected a hose from a tanker truck delivering sulfuric acid to a tank containing sodium hypochlorite. The reaction resulted in a cloud of chlorine gas being vented into the air. EPA responded to the incident to assess off site exposures and provide technical assistance to local responders.
