Notes

1. A serious pipeline safety incident is an event involving a fatality or injury requiring in-patient hospitalization.
2. 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.
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. All costs prior to 2008 are expressed in 2007 dollars. Costs in current year (2008) are nominal.
