Safety and environmental performance dashboard - June 2016

It is the National Energy Board’s (NEB) job to make sure companies are doing what it takes to keep their pipelines safe. The NEB does not simply make a decision or recommendation on a project and walk away. The NEB oversees safety for the full lifecycle of a project – from construction and operation to the end of its use. We hold those we regulate accountable so that the safety of Canadians and the environment is protected.

Pipeline incidents

Details
  • An event can be the result of one or more concurrent reportable incidents. A fire and a serious injury is an example of a single event with multiple reportable incidents.
Details
  • A significant adverse effect on the environment occurs when any chemical substance is released at a concentration or volume that has the potential to change the ambient environment in a manner that would cause harm to human life, wildlife or vegetation (e.g., glycol, potassium carbonate, methanol, methanol mix from hydrostatic testing, etc.).
  • Operation beyond design limit is typically linked to an over-pressure of the product in the pipe; however, if a pipe was exposed to excessive vibration and was not designed for this, this could be considered operation beyond design limits. Operation beyond design limits does not include equipment contacting the pipe, or corrosion pits, etc.
Details
  • The immediate cause(s) of an incident are the circumstances that directly lead to the occurrence of the incident. An incident may have more than one immediate cause.
Details
  • The basic cause(s) of an incident are the underlying reasons behind the immediate cause that explain why the immediate circumstances existed. An incident may have more than one basic cause.

Details
  • Volumes of natural gas releases are typically not estimated as there is no accurate method of estimating the release on a per event basis. As a result of this, the Onshore Pipelines Regulations require that companies report all unintended releases of natural gas regardless of volume.

Unauthorized Activities (UA)

Details

UAs:

  • every contravention of the National Energy Board Pipeline Damage Prevention Regulations – Authorizations;
  • all damage to its pipe caused or identified during the construction of a facility across, on, along or under a pipeline, the operation, maintenance or removal of a facility, an activity that caused a ground disturbance within the prescribed area or the operation of vehicles or mobile equipment across the pipeline; and
  • any activity related to the construction of a facility across, on, along or under a pipeline, an activity that caused a ground disturbance within the prescribed area or the operation of vehicles or mobile equipment across a pipeline that the pipeline company considers could impair the safety or security of the pipe.

Near Misses

Details
  • Near misses are predictors of future behaviour, so this metric is a leading indicator for events/incidents that may be prevented if the at-risk behaviour is changed. The NEB studies the data and looks for trends, outliers and indicators then will use the information to develop compliance verification and promotion plans.
