Rentech Nitrogen Partners, L.P. (NYSE: RNF) announced today that it has completed its evaluation of the equipment damaged in the fire that occurred in the ammonia synthesis loop of the ammonia plant at its East Dubuque, IL nitrogen fertilizer facility on November 29, 2013. The Partnership confirmed its previous estimate of $1 million to $2 million for the total cost of repairs due to the fire. As previously disclosed, Rentech Nitrogen intends to file a claim related to the incident under its property insurance policy, which has a deductible of $1 million. The Partnership anticipates the repairs, which are currently underway, to be completed within the next two weeks, with ammonia production of approximately 790 tons per day expected to resume on or before the first week of January 2014. Rentech Nitrogen continues to anticipate ammonia production at the increased rate of approximately 1,020 tons per day by the end of January 2014. Based on these schedules for repairs and production, the Partnership currently expects the overwhelming majority of the impact on deliveries of lost production due to the fire to occur in 2013, with minimal impact on previously forecasted deliveries for 2014.
