The incidents reported below are limited to Significant Incidents (A) over the period 1998 to 2008 only. Each year and selected column totals provide links to focused reports showing the causes of the corresponding incidents.

The data sources for this report are the PHMSA Filtered Incident Files (1) (2) (3) and several pipeline mileage data sources as described below.

• Hazardous Liquid - National Pipeline Mapping System (4)
• Gas Transmission - National Pipeline Mapping System (4)
• Gas Gathering - Calendar Year 2007 Annual Reports (5)
• Gas Distribution - Calendar Year 2007 Annual Reports (6)

All mileages are for the year 2007 and are approximate as some data sources may not contain a complete record of state pipeline mileage for the year 2007.

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 service lines (the connection between the distribution line and the end user) are not included in the Gas distribution mileage. The total number of such services is provided.
3. Costs in the current year (2008) are nominal (as reported). The costs for incidents prior to 2008 are presented in 2007 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 2007 dollars. Costs in current year (2008) are nominal.
5. Net Barrels Lost applies only to Liquid incidents and is the difference between Gross Barrels Lost and Barrels Recovered.
