All Reported Pipeline Incidents By Cause

This report is a sub-report of the PHMSA All Reported Pipeline Incidents report. As such, it represents All Reported Incidents over the time period and pipeline system specified.

It should be noted that hazardous liquid incidents within the All Reported Incidents data set include many smaller spills of lesser significance for which operators were not required to report second level, or sub-causes. As a result, the causes for these incidents can only be categorized within the appropriate "Unspecified..." sub-cause. These smaller spills with no specific sub-cause are not included in the Serious or Significant Incidents data sets by definition. The various "Unspecified..." sub-causes used below also include those older incidents which could not be mapped more specifically due to legacy form issues associated with each type of pipeline system.

It should also be noted that, due to the differing nature of the smaller hazardous liquid incidents being reported in 2002 and beyond, the cause breakdowns for the aggregated incidents will change for this time period as well.

The data source for this table is the PHMSA Flagged Incident File.(1)

More Pipeline Incidents and Mileage Reports are available.

Notes

  1. 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.
  2. 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.
  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.
