On april 22, 2018 at 08:10 atmos energy received notice of an incident that had occurred at 900 n. O'neal street in caldwell texas at 23:58 the previous day (april 21). Atmos energy representatives arrived on site at 08:45 on april 22 and discovered indications of natural gas present under o'neal street and in the sewer. The residents of 901 and 904 o'neal street were evacuated as a precaution while atmos energy completed its investigation along with representatives from the texas railroad commission. At approximately 13:30 atmos energy crews identified a leak near the location where the service line for 901 o'neal tapped into the gas main. The leak was eliminated, the service line to 901 o'neal was replaced, and gas service was restored by 20:00 on april 22.
