PHMSA has collected pipeline incident reports since 1970. The reporting regulations and incident report formats have changed several times over the years. PHMSA merged the various report formats to create pipeline incident trend lines going back 20 years.
The trend links to the right will initially present reports including all data for the incident type. The reports can be filtered by State and by System Type:
PHMSA also provides data about the causes of the incidents. Each link appearing with a trend line report leads to a new screen showing the incident causes. From this screen, you can also select a link to view details about the location of the incidents.
When a single System Type is selected, additional filters can be applied to the trend lines. Filters include Onshore/Offshore and Commodity (for Hazardous Liquid only).
SERIOUS INCIDENT 20 YEAR TREND – Serious Incidents include a fatality or injury requiring in-patient hospitalization. From 2004 forward, gas distribution incidents caused by a nearby fire or explosion that impact the pipeline system are excluded.
SIGNIFICANT INCIDENT 20 YEAR TREND – Significant Incidents are those including any of the following conditions, but gas distribution incidents caused by a nearby fire or explosion that impacted the pipeline system are excluded:
ALL-REPORTED INCIDENT 20 YEAR TREND – Includes all reports submitted to PHMSA. Changes to PHMSA reporting regulations have caused large shifts in the trend line.
SIGNIFICANT INCIDENT CONSEQUENCES – Since 2005, incident reports classify each fatality, injury, and cost as either Public or Pipeline Industry.
