Narrative
Texas county, ok emergency dispatcher received call from an unknown source reporting a small fire in a pasture. Fire department was dispatched. Dcp and wtg were also notified. Dcp notified badger first responder at 0045 on august 28, 2017. As a precautionary measure, badger responder notified breitburn plant to shut down pumps at 0045 on august 28, 2017. Leak was verified as being on the dry trails pipeline at 0104, august 28, 2017. Upstream block valve at straight valve set was closed at 0130, august 28, 2017, downstream block valve at midway valve set was closed at 0145, august 28, 2017. In order to provide double block and bleed, hooker valve set was closed at 0900, august 28, 2017. A small fire was allowed to continue to burn off vapors until flares could be installed. 24 hour security and monitoring was initiated. Upon product extraction, line was excavated for observation and repair methodology. Open hole inspection revealed no evidence of corrosion. Coal tar coating was found to be bonded and in very good condition. Recent ili data revealed the nearest anomaly (56 % metal loss) at 1636 feet downstream of the leak. A small pinhole was observed with surrounding coating blown away. The pinhole was surrounded by a half inch diameter pit with very shiny metal flow away from the pit. A very recent extreme source of heat and rapid cooling was determined to be the source. Due to a lightening storm reported in the area at the time of the incident, a lightening strike was considered as the most likely source. A decision was made to replace 13.5 feet of pipe. Metalurgical analysis in progress.
