CF Industries Holdings, Inc. announced that its entire Woodward, Okla., nitrogen complex is off-line due to a problem in one of the boilers. All of the plants in the complex were safely shut down with no impact on personnel, the surrounding community or the environment. The company estimates that it will take approximately six to eight weeks to return the plant to normal operations.

During the outage, the plant will execute the turnaround maintenance activities that had previously been scheduled for June. The Woodward complex has average annual production capacity for 480,000 tons of gross ammonia, 820,000 tons of UAN, and 25,000 tons of urea liquor. The company's sales organization is communicating with customers to work through product availability and delivery schedule implications.
