Notes
- Serious Incidents are those incidents reported by pipeline operators involving a fatality or injury requiring in-patient hospitalization.
- PHMSA has gathered increasingly targeted incident cause data over time. As such, the available reportable categories of cause (eg: Internal/External Corrosion vs Corrosion in general) have increased over time. This report spans time periods over which the reportable cause categories have changed. The cause categories in this report should be taken as general and not specific for years prior to 2002 for Liquid and Gas Transmission, and prior to 2004 for Gas Distribution.
- 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.
- The costs presented here are nominal (that is, as reported by the Operator at the time of the incident) and are not adjusted to account for commodity cost fluctuations or general inflation.
- 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.
