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. 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.
