This report is a sub-report of the PHMSA All Reported Pipeline Incidentsreport. 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 Incidentsdata 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 Seriousor

Significant Incidentsdata 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.

More Pipeline Incidents Reports are available.

Notes

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.

A.

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.

B.

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.

C.

Sources

PHMSA Flagged Incidents File- Sept 3, 2014. Note: Incidents occurring up to 30 days prior the Incident File source date may not

appear in these reports due to the 30-day reporting period allowed by PHMSA regulation.
