Thank you for the question.
Perhaps I could answer, but I would like to make a clarification first in connection with your question. Perhaps it should be addressed to my colleagues from the National Energy Board, because they are responsible for anything involving verification.
Generally, in a policy context,
the description of the ground disturbance and the conditions around ground disturbance would be considered when the board would hear the application for abandonment.
Should the pipeline that was proposed to be abandoned be in an agricultural area, the board may determine the conditions to require a further depth of requirement as a condition of abandonment versus the conditions related to what might be in a non-agricultural area or a rural area, or an area of forested cover, as it might be.
The considerations as to what was acceptable ground disturbance vis-à-vis an abandonment process would be taken into consideration during an abandonment hearing and may form conditions of abandonment. That's the first part of the answer.
On the question of who would verify and continue to monitor, it would be the role of the National Energy Board to continue to do so. Certainly, some potential landowner who might be impacted by an abandonment order would have knowledge of that order. It would be the board's responsibility to then communicate with that landowner vis-à-vis what would be conditions of limitations, if you will.
Generally speaking, the purpose of the ground disturbance is to establish a reasonable amount of land that may be disturbed before the safety of the individual disturbing the land might come into question.
