LSB Industries Reports on Unplanned Maintenance at Its Pryor Chemical Facility

LSB Industries, Inc. LXU today announced that its Pryor, OK Facility was shut down on March 15, 2012 for unplanned maintenance. Plant personnel have identified excess heat in areas of a high temperature, large diameter pipe in the ammonia plant. As a precautionary measure, ammonia plant production has been shut down while the pipe is removed and the cause of the excess heat determined and repairs performed. Maintenance has also been undertaken at the urea plant at the Pryor Facility over the preceding two weeks. During this period, when the urea plant has been undergoing maintenance, the Pryor Facility has not produced urea ammonium nitrate but has been producing and selling ammonia directly into the fertilizer market. The Company expects to resume ammonia and UAN production before March 31st. The Company plans to announce when ammonia and UAN production has resumed.
