Narrative
On november 29, 2018 at approximately 10:00 am, energy transfer's 4inch ngl s315 jameson plant lateral pipeline experienced a discharge caused by third party damage. The line is located in nolan county in maryneal, tx. A contractor performing work for another operator was operating a track-hoe with a shaker bucket and struck the energy transfer line and caused a leak. The contractor stated that when using the shaker bucket on the track-hoe to backfill his excavation, the track-hoe began sliding toward the ditch. The contractor laid his shaker bucket down to stop the sliding of his equipment and struck the pipeline. Energy transfer personnel noticed the gas cloud while heading to the excavation location and notified additional energy transfer employees at 10:06 am. These company personnel immediately proceeded to shut in the pipeline by closing in the upstream mainline valve and downstream mainline valve at 10:22 am and 10:40 am respectively. The affected pipe segment was cut out and replaced with pre-tested pipe. The pipeline was brought back to service on december 1, 2018 at approximately 10:00 am. Energy transfer will continue to execute procedures outlined within our damage prevention procedures and spread public awareness through our public awareness program to help prevent reoccurrences. This pipeline is under the jurisdiction of the texas railroad commission the txrrc was notified on november 29, 2018 at 3:43 pm. Incident # 1889
