Narrative
While performing an integrity assesment pressure test of the section of the line, a hydrotest was initially started at 1530 on may 16, 2 012. The section did not hold pressure at the 500 psi hold. A 50 gallon per hour leak was declared and the freeze plug crew was called out. A line inspector on an atv quickly found an approximately 10 gal/hr leak in the bank of a span upstream of the revere bv. The line was depressurized and an unsuccessful attempt to repair the leak with a patch was made. The leak was then clamped and the test resumed at approximately 2145. The section again did not hold at 500 psi and a 40 gal/hr leak was declared. The night of may 16-17 was spent freeze plugging and narrowing the search for the leak. After setting three freeze plugs and narrowing the leaking section to 7 miles, an active leak site with petroleum contaminated soil was discovered at approximate station 2219+74 at approximately 0930 on may 17, 2012. Notifications for the product leak were made. The leak was excavated and evaluated. A roll of woven wire fencing was excavated in close proximity to the leaking pit. Two pits were discovered in the same joint of pipe approximately 10 feet apart. 135 feet of pipe were replaced with new pipe. State of missouri dnr visited the site and approved of the repair and clean-up plan. The section was repressurized with water at 0130 on may 18, 2012.
