Narrative
A power outage at cowden station was reported on october 31, 2019 at 23:33 communications were lost at the mov #0014 mainline block valve. At 2350 a 3rd party notified houston control center of a fire near the block valve. Fire was extinguished at 0326 on november 1, 2019 with assistance from local fire department. Damages to the pressure transmitter line on the valve were sustained. The line was bypassed and the pipeline was safely started back up. Investigation determined that the leak came from a pin-hole on the pressure transmitter's tubing. The pin-hole was caused from the electrical fault currents on the pipeline after the power loss occurred. An investigation determined that the leak came from a pinhole on the pressure transmitter's tubing. A downed tree caused a power line to ground fault outside cowden station. The power line fault caused an electrical arc between tubing fittings, resulting in a pinhole leak in the pressure transmitter tubing. Initial nrc call was made november 1, 2019 at 01:35 nrc# 1262794. The 48 hour update was placed november 1 at 09:44 nrc #1262810.
