Narrative
On february 14, 2011 a contract survey crew noticed indications of a potential leak on a denbury right-of-way near beaumont, texas. They reported the leak to denbury operations and regulatory personnel at approximately 1:00pm. Upon further investigation, the location of the potential leak was at a crossing with two other pipelines. Denbury elected to have a contractor excavate to confirm that the leak was from our pipeline or from another source. It was confirmed that the leak was from denbury's pipeline at 5:30pm. The initial cost to repair the leak was estimated at $90,000, which would require national response center telephonic reporting. The nrc report was electronically submitted at 7:12pm. The leak rate was estimated at 2 gallons per hour. Isolation of the line segment was accomplished on february 16, 2011 at 4:00pm. The line was blown down from mlv-22 to the beaumont station (15.8 miles). On february 17, 2011, troy construction began line repair work. Other project details and logistics were confirmed, including moving pre-tested pipe from the winnie, texas yard to the jobsite and making coating repairs to the pre-tested pipe. Oq and drug and alcohol plans were confirmed with all participating contractors and their personnel. With blowdown of the line complete and a pre-job safety meeting conducted, air movers were installed at mlv-24 and beaumont station in preparation to replace leaking pipe 300 yards east of beaumont station. Removed the leaking 24' 46' long joint and made 1 weld on replacing pipe. X-ray was accepted. Made second tie in weld on new section of pipe. X-ray was accepted.
