Narrative
On 10/31/2014 the dover to hennessey pipeline was shut down by the control center due to an over/short line imbalance. Air patrol was dispatched, flew the line and reported no visible signs of a release. The line remained shut down overnight. On 11/1/2014 a pressure integrity check of the pipeline was initiated and aborted when the line did not hold pressure. Foot patrol along the line on 11/1/2014 identified and confirmed the point of release. The release site was excavated, the line was purged and the failed section of pipe was cut out and replaced. The line was subsequently successfully hydrostatically pressure tested. The line was placed back into service on 11/7/2014. On january 23, 2015 it was determined that remediation costs would cause total costs to exceed $50,000. Therefore an nrc notification was made per the requirement defined under 195.52(a)(3). Metallurgical analysis revealed that the failure was the result of a pre-existing weld flaw produced in the pipe mill during manufacture.
