Narrative
At 0811 4/6/2013 pipeline control received a third party call reporting oil was on the ground near our delivery point at lhr. The oil appeared to originate from a vent pipe near the manifold. A technician was dispatched to the site to investigate. On arrival (0834) he confirmed that there was an area approximately 20 x 20 yds covered with oil. The pipeline was down at the time of discovery. This facility is located near highway 225 and scarborough lane in pasadena, texas. There are no injuries, evacuations, or fire. No waterways were affected. The leak was underground near a low point in the pipeline. Sections were cut out and sent for metallurgical analysis. Metallurgic reports indicated that the failure mechanism was internal corrosion caused by salt water entrained in the crude oil which segregated to the bottom of the pipeline becoming trapped at a low point near a weld. Pipe was replaced and line put back in service. Pig launcher/receivers installed to assist in cleaning water from low points in the line as a preventive measure. An initial report was filed with the nrc petty officer layman at 0931 with an unknown volume, report #1043112. A second report was filed with nrc petty officer layman at 1015 report #1043116 to update the known release amount. The trrc/serc report number is #2013-11-08.
