Narrative
On 8/1/2013, an aerial patrol pilot informed the jackson station technician of dead vegetation near am 428. The technician drove to the site and discovered a 15' radius of stunted growth of corn above enterprise's west leg blue line. The technician found elevated lel at ground level in the cracks of the ground. The line was not running at the time. The technician informed pipeline control who lowered pressure on the line. The leaking segment was then blocked in between am 422 and am 432. The area was excavated and a small bubble leak was found at the thread of the bleeder valve on the stopple blind flange. The leak stopped and lel readings were not detected once the bleeder valve was tightened. To mitigate future leak potential due to failure at the thread, a tor was welded on the blind flange to encase the bleeder valve. The pipeline was restarted on 8/9/2013 at 10:00 am.
