Incident Data Access

Download the raw data used to generate the reports above.

The reports provided here are generated from numerous data sources maintained by PHMSA. These data sources span decades of collection, evolving methods of oversight and multiple reporting formats. To generate these reports, PHMSA has standardized the data over various file formats, normalized incident costs over time to a common basis year, and standardized incident cause categories - all with the goal of producing a coherent and meaningful picture of National and State-specific trends in pipeline incidents. Should you prefer to produce your own analysis, the raw data used in these reports is available.

Please note that in some of these reports, the costs associated with incidents are provided in 2013 dollars. We have converted the cost of gas lost during a pipeline incident using the Energy Information Administration, Natural Gas City Gate Prices. For all other costs, we applied the Bureau of Economic Analysis, Government Printing Office inflation values.
