Narrative
On 12/5/10 at 13:00 a hunter notified nustar control center regarding an ammonia odor near valve 6-14. The pipeline was shutdown at 13:15. On 12/5/10 at 14:00 a nustar technician arrived on-site and confirmed that an ammonia odor was present. On 12/6/10 at 8:00 nustar resources arrived on-site to begin excavation of the stopple tee. On 12/6/10 at 14:00 nustar uncovered the leak site and was able to capture anhydrous ammonia drips in a 15 second interval and extrapolated that amount. Based on the field calculation it was determined the leak would exceed the reportable quantity. At 15:05 on 12/6/10, nustar contacted the nrc to make notification of a reportable leak incident. Anhydrous ammonia was leaking from a failed o-ring in a threaded fitting from the stopple tee. The repair was made by welding in the segment plugs.
