March 27 — Atmos’ reluctance to evacuate the Irving neighborhood is similar to the company’s actions in northwest Dallas last month. On Feb. 21, a house on Durango Drive in Dallas exploded because of a gas leak. The next day, another house caught fire – again ignited by leaking natural gas. Still Atmos did not evacuate the neighborhood. It wasn’t until Feb. 23 when a third house on nearby Espanola Drive exploded, killing 12-year-old Linda “Michellita” Rogers, that Atmos evacuated residents and embarked on an unprecedented mass replacement of gas lines servicing about 2,800 homes.
