CF Industries Holdings, Inc. (NYSE:CF) today reported that it is in the process of restarting operating units at its Medicine Hat, Alberta, nitrogen complex. The company had shut down production at the complex as a precautionary measure on June 23rd. The site on which the complex is located is approximately 200 feet above the normal river level. However, the pump house containing equipment used to draw river water for plant operations is near the river bank. The pump house equipment that had been relocated to higher ground prior to the flooding has been reinstalled and is back in service. "We have determined that it is safe to restart our operating units and are doing so. We are in contact with our customers regarding the status of deliveries from the facility," commented Tony Will, senior vice president, manufacturing and distribution, CF Industries Holdings, Inc. “Our thoughts are with those in the community who were impacted by the flooding.” About CF Industries Holdings, Inc.
