State investigators have ruled out inadequate maintenance as the cause of an explosion at a natural gas plant in southwestern Wyoming in April, but are still looking into what did happen. The explosion at the Williams Company gas plant forced evacuation of the nearby town of Opal.
John Ysebaert heads up Wyoming’s Office of Occupational Safety and Health. He says the state sent two investigators to look into the incident, and so did the U.S. Chemical Safety Board. Ysebaert says that agency doesn’t normally get involved.
