Safety Performance Portal - December 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[1] 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.

[1] Total kms include pipeline that is approved, under construction, operational, deactivated, decommissioned, and pending abandonment.

Pipeline Incidents

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: Details
  • Figure 1 shows the number of events which occurred from 2008 through to 2015 that resulted in a reportable incident (or incidents).
  • In 2015, there were 91 events reported under the OPR; 89 events had a single reportable incident and two events 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.

Figure 5: Details
  • There have been 13 incidents related to OBDL in 2015, as follows:
    • Two were related to 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;
    • Three involved over-pressure that occurred when thermal expansion caused an increase in pressure in the pipeline, and either the thermal relief valve failed to open, or the relief valve didn’t relieve the pressure quickly enough to avoid exceeding the line’s limits;
    • Two involved an outage at a compressor station which resulted in an overpressure in the line;
    • One occurred during maintenance work when expansion joints on an exhaust duct failed;
    • One involved off-specification gas entering a meter station due to an error upstream;
    • One occurred when a pipeline was started against a closed valve and the relief valve failed to open, setting off an alarm in the Control Centre;
    • One involved an overpressure found during a review of pipeline operating pressures in a new segment of pipe;
    • One occurred when a flow control valve closed unexpectedly and the relief system did not activate during a delivery; and,
    • One occurred when a block valve did not close completely resulting in off-specification gas being flared.

Figure 7: Details
  • Five reportable liquid releases occurred in 2015 as follows:
    • A leak overflowed the secondary containment around a valve and spilled 1.5 m3 of crude oil which did not leave company property;
    • A leak from a pump spilled 2.0 m3 of lube oil which did not leave company property;
    • A leak totaling 16.0 m3 of crude oil occurred from a booster pump. Of this volume, 15.0 m3 was contained by the secondary containment around the pump, and 1.0 m3 spilled onto adjacent soil affecting an area of 10 m x 10 m. Vacuum trucks were used to assist with the clean-up and restoration of the site.
    • A leak of 30 m3 occurred when a crew was conducting work on a discharge line from a tank. All the released liquid was contained within the tank lot.
    • A leak occurred during a pump upgrade spilling 4 m3 of crude oil which did not leave company property.
