Narrative
On 5/11/2015, a leak was discovered on lid 333-2 at 10:30 hrs while pipeline rehab crew was working on anomalies by removing coating and sandblasting. It was determined that the repair would exceed $50,000 at 14:30 hrs. Therefore the nrc call was made at 15:09 hrs. Line was isolated, purged with nitrogen, repaired with a replacement of 40ft of new pipe. Pipe was sent for metallurgical analysis. Update 8/13/2015 - it was determined by the metallurgical analysis that the leak was caused by through-wall selective seam-weld corrosion. An engineering analysis will be performed to determine if there are any other anomalies of this kind.
