The Georgia Environmental Protection Division (EPD) has opened an investigation into Becton Dickinson’s (NYSE:BDX) medical device sterilization plant in Covington, Ga. following an eight-day leak of the sterilant gas ethylene oxide (EO).

The EPD notified BD this week that it was dissatisfied with the company’s reporting of the valve leak that released 54 lbs. of ethylene oxide into the air between Sept. 15 and Sept. 22, according to an email statement to Medical Design & Outsourcing. BD has said that it closed the valve as soon as it discovered it was the source of the leak, and that it notified the city of Covington and the EPD.
