Significant Pipeline Incidents

This Significant Incident data set is designed for historical trending and includes adjustments to account for commodity cost fluctuations and general inflation.

PHMSA defines Significant Incidents as those incidents reported by pipeline operators when any of the following specifically defined consequences occur:

  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

PHMSA established a cost reporting threshold of $50,000 for gas pipeline incidents in 1984. Since then, inflation and the rapid rise in the cost of natural gas have caused the cost of incidents to rise significantly along with an increase in the number of incidents reported. To account for the cost increases, PHMSA now considers incidents significant from a cost perspective if they exceed a total cost of $50,000 in 1984 dollars.

We have converted the cost of gas lost during a pipeline incident using the Energy Information Administration, Natural Gas City Gate Prices.(A) (1) For all other costs, we applied the Bureau of Economic Analysis, Government Printing Office inflation values.(A) (2) The costs shown in the tables are in adjusted dollars.

The tables below show the number of Significant Incidents in a year for each type of pipeline operator. Each year and selected column totals provide links to focused reports showing the causes of the corresponding incidents.

The data source for this table is the PHMSA Flagged Incident File. (3)

Where appropriate, the table columns can be sorted by clicking the corresponding column header.

There is also a designation for Serious Incident which counts only incidents involving a fatality or injury. See Serious Pipeline Incidents for information on this smaller subset of incidents.

More Pipeline Incidents Reports are available.

Notes

  1. 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.
  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. 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.
  6. Does not include 1,851 injuries that required medical treatment reported for the October, 1994 accidents that were caused by severe flooding near Houston, Texas.
  7. Approximately 94% of the Property Damage for Gas Distribution Incidents in 2005 was caused by flooding in New Orleans. The $466.5 million associated with this incident represents lost gas and operator property damage, but does not include damage to public and private property caused by the flooding.
