Energy Transfer issued the following statement:

This morning in La Porte, Texas, a fire occurred at a valve station for a 20″ LPG line on Spencer Highway. There are currently no reports of injuries. The LaPorte Fire Department is on scene and has evacuated all homes and businesses within a half mile of the accident scene. The line has been isolated to allow any residual product contained within to burn out safely. We do not currently have a timeline for how long this process will take, but are working closely with local authorities. We have received initial reports of an unknown passenger vehicle entering our right-of-way and striking the valve station. Air monitoring equipment is currently being set up in the area. We will release more details as they become available.
