More on this Data

The map displays only "significant incidents," defined by PHMSA, the Pipeline and Hazardous Materials Safety Administration, as those that caused either a death or serious injury, cost more than $50,000, released more than 50 barrels of liquid, or caused a fire or explosion (see the official definition here). It includes incidents through Sept. 28, 2012. Many incidents lack sufficient location data and do not appear on the map.
