Narrative
On january 19, 2021, a farmer struck a farm tap off of line kc 17 with a plow near hawley, texas. Atmos energy was notified of the incident at 10:03 am, at which point work began to determine how to make repairs. The decision was made to squeeze off the 1.25" steel riser and after the squeeze off occurred at approximately 1 pm, it was discovered that a threaded connection was leaking under the squeezed off section of the riser. Work then began on a bypass on kc17 to ensure continued service on the line. At the point it was determined a bypass would be needed to make the necessary repairs, it was anticipated that the cost associated with repairing the damage would exceed $50,000. A call was made to the national response center at 16:17 ct on 1/19/2021. Stopples were welded on for the bypass, which was completed on january 20, 2021. On january 21, 2021, 5 feet of 12" pipe was replaced and line kc17 was then returned to normal operation.
