Notes

  1. Significant Incidents are those incidents reported by pipeline operators when any of the following conditions are met: 1) Fatality or injury requiring in-patient hospitalization. 2) $50,000 or more in total costs, measured in 1984 dollars. 3) Highly volatile liquid releases of 5 barrels or more or other liquid releases of 50 barrels or more. 4) Liquid releases resulting in an unintentional fire or explosion. Serious incidents, a subset of Significant Incidents, are incidents which involve a fatality or injury requiring in-patient hospitalization.
  2. The costs for incidents in 2013 and prior are presented in 2013 dollars. Cost of Gas lost is indexed via the Energy Information Administration, Natural Gas City Gate Prices. All other costs are adjusted via the Bureau of Economic Analysis, Government Printing Office inflation values.
  3. For years 2002 and later, property damage is estimated as the sum of all public and private costs reported in the 30-day incident report. For years prior to 2002, accident report forms did not include a breakdown of public and private costs so property damage for these years is the reported total property damage field in the report.
  4. Starting Sept 2013, this column displays "volume released unintentionally" for all years after 2009. Before Sept 2013, the column displayed the sum of "volume released unintentionally" and "volume released intentionally" for all years after 2009.
  5. Net Barrels Lost applies only to Liquid incidents and is the difference between Gross Barrels Spilled and Barrels Recovered.
