A supposedly abandoned gas line developed a small hole due to corrosion of the metal. It was determined that the line was never isolated from the new line and was under pressure. When the corroded point finally failed, produced water and condensate that had accumulated in the line migrated to the surface under pressure. Due to the extremely cold conditions at the time of the release, the majority of the fluids infiltrated into the snow cover on the ground and very little actually impacted the sub surface soils, with the exception of the immediate vicinity around the release point. The area of impacted snow was delineated and BMPs placed around it for containment. Next, the shrubbery and snow were removed. The snow was placed into a metal containment and allowed to melt. Once melted it was transported off-site. The soils in the immediate vicinity of the leaking line were excavated and had levels below regulatory standards. The line was capped where it tied into the new line and permanently abandoned. The impacted area below the release was tested and was below regulatory standards. The area was then restored to its original condition.
