CF Industries Holdings, Inc. (NYSE: CF) today announced the temporary halt of production at its Port Neal nitrogen manufacturing complex in Sergeant Bluff, Iowa, located near Sioux City on the Missouri River. The company is taking this step as a precautionary measure until the impact of rising water levels is known.

Commenting on the decision, CF Industries Vice President of Manufacturing and Distribution Tony Will said, "In preparation for potential flooding at Port Neal, we are nearing completion of construction of an earthen berm that we believe will protect the plant. We appreciate the extraordinary efforts of our employees at Port Neal and from other CF Industries locations in the region to protect our assets and ensure safe operations.
