Q

What are three things to note what assessing with your impact significance equation?

A
  • Not all potential impacts can be considered;
  • Not all impacts should be considered to the same level of detail; and
  • Impacts vary in their decision-making importance

17
Q

What does Vulnerability mean in the context of Significance?

A

A series of parameters related to the stress to which a VC is exposed because of pre-existing impacts or sensitivities or other types of stressors that reduces the resilience of a system.

18
Q

Know the Vulnerability spectrum:

A

Chapter 7

19
Q

What piece of legislation entrenches Indigenous and Treaty rights and imposes an obligation to governments on justifying any interference with the exercise of those rights?

A

20
Q

What speaks to the understanding of community context?

A

Guidance and Indigenous Knowledge under the Impact Assessment Act.

21
Q

Remember the Federal Overview of Methodology:

A

Chapter 7

22
Q

What are the four Sustainability Principles?

A
  1. Interconnectedness and interdependence of human-ecological systems.
  2. Well-being of present and future generations.
  3. Positive effects and reduce adverse effects of a designated project; and
  4. Apply the precautionary principle and consider uncertainty and risk of irreversible harm.
23
Q

What are the five public interest factors of the federal policy framework on the determination of public interest?

A
  1. The extent to which the designated project contributes to sustainability.
  2. The extent to which the adverse effects within federal jurisdiction and the adverse direct or incidental effects that are indicated in the Impact Assessment Report in respect to the designated project are significant.
  3. The implementation of the mitigation measures that the Minister or the governor in council considers appropriate.
  4. The impact that the designated project may have on any Indigenous group and any adverse impact that the designated project may have on the rights of the Indigenous Peoples of Canada, recognized and affirmed by Section 35 of the Constitution Act.
  5. The extent to which the effects of the designated project hinder or contribute to the Government of Canada’s ability to meet its environmental obligations and its commitments in respect to climate change.

  • Consideration of uncertainty in the factors considered
33
Q

When making sense of Significance in EIAs, you should do what four things?

A
  • Have a clear operational framework for how significance is determined.
  • Focus attention only on significant issues.
