Maps of Pipeline Failures by State – 1/1/10 to 11/30/18 (From 2002 for California)
People often wonder about the failures of pipelines in their areas. To help people visualize how often pipelines fail we have created maps that allow you to examine failure information state by state, and the pop-up windows will provide reported information on each failure as you select it. We have provided some basic information about each failure such as type of pipeline, operator, cause of the failure, how much product escaped, size and pressure of pipeline, numbers of injuries or fatalities, etc. We did this work on the CARTO mapping platform with a generous grant from CARTO.
We started this project in California, where we have included all the failures since 2002, but because of storage space limitations, we are currently showing only failures since 2010 in all others states. All of this uses PHMSA incident data, which PHMSA updates at the end of each month. We hope to update the maps nearly as often. We have also included population density overlays in many states, but again because of storage limitations you will not find that in every state. As this mapping effort evolves, we hope to include additional information.
The only failures shown on these maps are from pipelines that fall under the PHMSA regulations, which includes about 2.7 million miles of pipelines. There are at least another 300,000 miles of pipelines that are not covered by PHMSA’s regulations and often are not covered by any regulations at all. These would include many production, rural gathering, produced water, and other types of pipelines. Incidents on those pipeline, while perhaps significant, will not show up on these maps.
All of these failures are based on the following definitions in PHMSA’s regulations:
Reportable Incident for Gas Distribution, Gas Gathering, Gas Transmission, and Liquefied Natural Gas (LNG) Systems
Current PHMSA Regulation – §191.3 Definitions
“Incident” means any of the following events:
(1) An event that involves a release of gas from a pipeline, or of liquefied natural gas, liquefied petroleum gas, refrigerant gas, or gas from an LNG facility, and that results in one or more of the following consequences:
(i) A death, or personal injury necessitating in-patient hospitalization;
(ii) Estimated property damage of $50,000 or more, including loss to the operator and others, or both, but excluding cost of gas lost;
(iii) Unintentional estimated gas loss of three million cubic feet or more;
(2) An event that results in an emergency shutdown of an LNG facility. Activation of an emergency shutdown system for reasons other than an actual emergency does not constitute an incident.
(3) An event that is significant in the judgment of the operator, even though it did not meet the criteria of paragraphs (1) or (2) of this definition.
Reportable Accident for Hazardous Liquids Systems
Current PHMSA Regulation – §195.50 Reporting accidents.
An accident report is required for each failure in a pipeline system subject to this part in which there is a release of the hazardous liquid or carbon dioxide transported resulting in any of the following:
(a) Explosion or fire not intentionally set by the operator.
(b) Release of 5 gallons (19 liters) or more of hazardous liquid or carbon dioxide, except that no report is required for a release of less than 5 barrels (0.8 cubic meters) resulting from a pipeline maintenance activity if the release is:
(1) Not otherwise reportable under this section;
(2) Not one described in §195.52(a)(4);
(3) Confined to company property or pipeline right-of -way; and
(4) Cleaned up promptly;
(c) Death of any person;
(d) Personal injury necessitating hospitalization;
(e) Estimated property damage, including cost of clean-up and recovery, value of lost product, and damage to the property of the operator or others, or both, exceeding $50,000.
