Narrative
On august 30, 2017 crews were surveying the row on the 6" midland to monument segment number 23373 and discovered dead vegetation on the row. At 12:05 area rep confirmed we had a small leak which was stopped with plidco clamp. Permanent repairs will be completed at a future date. Updated 5/20/2019 - neal jones: section of pipe containing the leak was removed on 5/11/2018, new pipe was installed and pipeline was returned to service. Pipe was inspected by oneok personnel who determined the release was caused by an anomaly in the long seam weld. It is believed the anomaly had been present since the manufacture of the pipe.
