Narrative
On 9/25/2014 at approximately 10:45 hrs, pipeline control received a call from enterprise contractor reporting a pinhole size leak on valve on its p74 near mile post 29. The leak resulted from the contract crew sandblasting the valve body in order to prime and paint the valve site. At 13:23 hrs. On 9/25/2014, it was determined that the repair would cost more than $50k and was reportable to the nrc. The pipeline was stoppled, the old valve was removed, and a new valve installed. The line was returned to service on 9/28/2014. Per the metallurgical analysis performed on the failed valve by kiefner and associates, "the leak was caused by a manufacturing defect of interconnected porosity that created a leak path through the body of the valve."
