Notes

  1. Significant Incidents are those incidents reported by pipeline operators with 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. Note: Significant Incidents include all Serious Incidents. Unless otherwise noted, any counts of Significant Incidents also include Serious Incidents.
  2. Gas Distribution incidents where fire/explosion was the primary cause of failure, such as a house fire that subsequently resulted in - but was not caused by - a distribution line failure are excluded from 2004 onward. This exclusion has not been applied in years prior to 2004 due to difficulty in identifying these types of events with the older report formats.
  3. The costs for incidents prior to 2008 are presented in 2008 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.
  4. 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. All costs prior to 2008 are expressed in 2008 dollars.
  5. Net Barrels Lost applies only to Liquid incidents and is the difference between Gross Barrels Spilled and Barrels Recovered.
