Mosheim, Tenn.—U.S. Nitrogen Co. LLC (USN) said Sept. 6 that it has identified and corrected the issue that led to a malfunction during a startup of its nitric acid plant Aug. 23 (GM Sept. 2, p. 13). Emissions were released, and locals soon posted photos of the orange cloud above the facility. USN was back in startup mode again last week, and said it was fully cooperating with the Tennessee Department of Environment and Conservation. It continues to anticipate being fully operational in the next few weeks.
