Narrative
On december 1, 2021, at approximately 11:00 am, an atmos energy employee and an independent third-party contractor were onsite at a valve site on line wn2-8, near 7786 county road 24 in frisco, tx. The independent third-party contractor was in the process of replacing the wrench head mounting plate with an actuator mounting plate when he was injured. An unknown part of the valve ejected and struck him in the face, resulting in injury. The atmos energy employee was about 10 feet away and was not involved in the independent third-party contractors work. The atmos employee onsite called 911, and the independent third-party contractor was taken to the hospital and admitted for treatment. The pipe was not shut down due to the incident. Later in the day, the valve was investigated for leaks and none were found. The third-party contractor has written procedures that apply to the installation of the actuator. Due to the circumstances of this event, the estimated volume of commodity released, if any, is de minimis or otherwise unmeasurable. Therefore, atmos energy has responded to question a7 with 1.00, which is the minimum value allowed. Out of an abundance of caution, the valve was replaced at the cost of $57,584. For this reason, the replacement cost was entered in part d 7 (d).
