Narrative
Additional nrc report no. 1231039 on november 20, 2018, a 3rd party contractor was moving dirt off of atmos energy's row to use as fill dirt for a concrete project nearby. Atmos energy had received a locate ticket from a different contractor that included the area where the damage occurred and the scope of the ticket was marked properly. However, the contractor that caused the damage did not request a locate for the excavation that resulted in this incident. This row contains a high pressure distribution 16 inch pipeline with operating pressure of approx. 300 pounds. The contractor's employee operating the bobcat skid steer within the marked tolerance zone hit the atmos energy c-16 pipeline with the bucket tooth and damaged the line, which resulted in an indention in the pipe with a small crack within the indention where gas was released. The contractor notified atmos energy of the incident at 13:10, and atmos crews arrived at the site at 13:57. A permanent repair was made on november 29 by installing 5' of 16" steel pipe.
