Safety Performance Portal - March 2015
The safety of Canadians and protection of the environment in the construction, operation and abandonment of pipeline facilities regulated by the NEB are the Board’s top priorities, and have been a part of our mandate since 1959. We hold those we regulate accountable so that the safety of Canadians and the environment is protected.
In 2013, the NEB regulated approximately 73,000 kilometres of interprovincial and international pipelines. See a map of the NEB’s regulated pipelines. The safety and environmental performance data and information that follows relates to the NEB’s regulated pipelines.
 Total kms include pipeline that is approved, under construction, operational, deactivated, decommissioned, and pending abandonment.
Under the National Energy Board Onshore Pipeline Regulations (OPR), companies must immediately notify the National Energy Board (NEB) of any incident that relates to the construction, operation or abandonment of a pipeline.
Incident means an occurrence that results in:
- the death of or serious injury to a person;
- a significant adverse effect on the environment (referred to below as significant adverse effects);
- an unintended fire or explosion;
- an unintended or uncontained release of low vapour pressure hydrocarbons (referred to below as Liquid releases) in excess of 1.5 m³;
- an unintended or uncontrolled release of gas or high vapour pressure hydrocarbons (referred to below as Gas releases); and,
- the operation of a pipeline beyond its design limits (OBDL).
To enhance the analysis of the reportable incident data, the NEB has separated serious injuries incidents from fatalities, and unintended fires from unintended explosions.
Figure 1: Total Number of Events Resulting in Reportable Incidents 2008 – Jan-Mar 2015
Figure 1: Details
- Figure 1 shows the number of events which occurred from 2008 through to 31 March 2015 that resulted in a reportable incident (or incidents).
- For the first three months of 2015 there were 17 events reported under the OPR; 16 events had a single reportable incident and one event had multiple reportable incidents.
- An event resulting in both a fire and a serious injury is an example of an event with multiple reportable incidents. Figure 2 breaks out each of these incident types by year.
|Year||Single Reportable Incident Event||Multiple Reportable Incident Event||Total Events|
Figure 2: Total Number of Events Resulting in Reportable Incidents 2008 – Jan-Mar 2015
Figure 2: Details
- Figure 2 compares the number of reportable incidents by type in 2014 with the number of reportable incidents for January – March 2015. Subsequent figures further detail a selection of the different incident types.
- With respect to significant adverse effects on the environment, no incidents were reported in the first three months of 2015.
- Most reportable incidents do not result in threats to the safety of people or the environment.
|Year||Gas Releases||Fires||Explosions||Serious Injuries||Significant Adverse Effects||Fatalities||Liquid Releases||OBDL|
Figure 3: Number of Serious Injuries 2008 – Jan-Mar 2015
Figure 3: Details
- There were no serious injuries in the first three months of 2015.
Figure 4: Number of Fatalities, 2008 – Jan-Mar 2015
Figure 4: Details
- There were no fatalities in the first three months of 2015.
Figure 5: Number of Operation Beyond Design Limits (OBDL) Incidents, 2008 – Jan-Mar 2015
Figure 5: Details
- There were three incidents related to OBDL so far in 2015 as follows:
- Two were related the testing of newly installed equipment at a station, which caused the pipelines to shut down and lead to an over-pressure in nearby meter stations; and,
- One involved an over-pressure that occurred when thermal expansion caused an increase in pressure in the pipeline, and the thermal relief valve failed to relieve the pressure.
Figure 6: Number of Fires and Explosions, 2008 – Jan-Mar 2015
Figure 6: Details
- Three fires and one explosion have been reported so far in 2015 as follows:
- One small flame was found at the connection of a welding tool;
- One flare occurred when a worker was using a propane torch to prepare a pipe joint for coating, and gas released from the propane tank that the torch was attached to;
- One flash occurred along a propane hose when a worker was preheating a weld; and,
- An explosion happened in an electrical switchgear room when attempting to start a pipeline.
Figure 7: Total Volumes of Liquids Released Vs. Number of Liquid Releases, 2008 – Jan-Mar 2015
Figure 7: Details
- In the first three months of 2015, one reportable liquid release occurred from a valve which overflowed the secondary containment around the valve and spilled 1.5 m3 of crude oil which did not leave company property.
|Year||Total Volume Released (m³)||# of Releases|
Figure 7(a): On/Off Company Property Liquid Releases by Location, 2008 – Jan-Mar 2015
Figure 7(a): Details
- Between 2008 and 2014, there have been a total of five liquid releases off company property.
- The one liquid release which was reported in the first three months of 2015 was entirely contained within company property.
|On Company Property||Off Company Property|
Figure 8: Number of Natural Gas and Other High Vapour Pressure Releases, 2008 – Jan-Mar 2015
Figure 8: Details
- There were 9 reportable natural gas and other high vapour pressure releases in the first three months of 2015. Of these, six were sweet natural gas, one was sour natural gas, one was propane and one was fuel gas.
Please note that ruptures are a type of unintended or uncontrolled liquid or gas release incident. For more detailed information on ruptures, please refer to the Pipeline Ruptures section of the NEB’s website.
Figure 9: Number of UAs by Province, 2013 – Jan-Mar 2015
Figure 9: Details
- The eight UAs in British Columbia included seven ground disturbances and three encroachments. The six UAs in Alberta included one ground disturbance, three encroachments and two vehicle crossings. The three UAs in Ontario were all ground disturbances. There was one unauthorized vehicle crossing in Saskatchewan.
Figure 10: Number of UAs by Type, 2010 – Jan-Mar 2015
Figure 10: Details
- The data so far in 2015 shows that ground disturbance continues to be the most prevalent type of UA.
Figure 11: Number of UAs by Violator Type, 2010 – Jan-Mar 2015
Figure 11: Details
- Consistent with trends from 2010 through 2014, contractors continue to be the leading type of violator so far in 2015.
Figure 12: Number of UAs by First-Time Vs. Repeat Violators, 2010 – Jan-Mar 2015
Figure 12: Details
- The trend in the number of first-time vs. repeat violators continued in the first three months of 2015, with more first-time violators than repeat violators.
Please note: The incident data shown represents a single point in time. As investigations are completed for open incidents, or as new information becomes available, the incident record is updated and may change certain aspects of the incident record including whether the incident remains reportable under the applicable regulations. Accordingly, the incident data shown is subject to change.
