Environmental Impact Assessment

• An environmental impact assessment is an assessment of the possible positive or negative impact that a proposed project may have on the environment, together consisting of the environmental, social and economic aspects.


• The purpose of the assessment is to ensure that decision makers consider the ensuing environmental impacts when deciding whether to proceed with a project.


• The International Association for Impact Assessment (IAIA) defines an environmental impact assessment as “The process of identifying, predicting, evaluating and mitigating the biophysical, social, and other relevant effects of development proposals prior to major decisions being taken and commitments made."


• EIAs are unique as they do not require adherence to a predetermined environmental outcome, but rather they require decision-makers to account for environmental values in their decisions and to justify those decisions considering detailed environmental studies and public comments on the potential environmental impacts of the proposal.


• EIAs began to be used in the 1960s as part of a rational decision making process.

• It involved a technical evaluation that would

lead to objective decision making.


• EIAs have often been criticized for having too narrow spatial and temporal scope.

• At present no procedure has been specified for determining a system boundary for the assessment.

• The system boundary refers to ‘the spatial and temporal boundary of the proposal’s effects’.


• This boundary is determined by the applicant and the lead assessor, but in practice, almost all EIAs address the direct, on-site effects alone.

• However, as well as direct effects, developments cause a multitude of indirect effects through consumption of goods and services, production of building materials and machinery, additional land use for activities of various manufacturing and industrial services, mining of resources etc.


• The indirect effects of developments are often an order of magnitude higher than the direct effects assessed by EIA.

• Large proposals such as airports or ship yards cause wide ranging national as well as international environmental effects, which should be taken into consideration during the decision-making process.


• Broadening the scope of EIA can also benefit threatened species conservation.

• Instead of concentrating on the direct effects

of a proposed project on its local environment, some EIAs used a landscape approach which focused on much broader relationships between the entire population of a species in question.


• As a result, an alternative that would cause least amount of negative effects to the population of that species as a whole, rather than the local subpopulation, can be identified and recommended by EIA.


• At the end of the project, an EIA should be followed by an audit.

• An EIA audit evaluates the performance of an EIA by comparing actual impacts to those that were predicted.

• The main objective of these audits is to make future EIAs more valid and effective.


The two main considerations are: • Scientific - to check the accuracy of

predictions and explain errors.

• Management - to assess the success of mitigation in reducing impacts.


• The Canadian Environmental Assessment Act (CEAA) is the legal basis for the federal Environmental Assessment (EA) process.

Risk Assessment

• Risk assessment is a step in a risk management procedure.

• Risk assessment is the determination of quantitative or qualitative value of risk related to a concrete situation and a recognized threat (also called hazard).


• Quantitative risk assessment requires calculations of two components of risk, the magnitude of the potential loss, and the probability that the loss will occur.


• In all types of engineering of complex systems, sophisticated risk assessments are often made within Safety engineering and Reliability engineering when it concerns threats to life, environment or machine functioning.


• The nuclear, aerospace, oil, rail and military industries have a long history of dealing with risk assessment.

• Also, medical, hospital, and food industries, control risks and perform risk assessments on a continual basis.


• Methods for assessment of risk may differ between industries and whether it pertains to general financial decisions or environmental, ecological, or public health risk assessment.


• So Risk assessment is a critical element of environmental management.

• In this course we begin by examining the

definition of risk in the context of environmental management.


• We look at ways to assess environmental risk in terms of effects on human health and safety; difficulties inherent to such analyses (e.g., cumulative and synergistic effects, uncertainty) are addressed.


• In addition to direct human impacts, environmental risk also implies threats to non-human species and entire ecosystems (the effects of which may in turn indirectly threaten humans).


• Risk assessment is just the beginning of the story when it comes to the role of risk in environmental management.

• We will consider different approaches to risk

management (prevention, mitigation, compensation) as well as the regulatory and legislative context to risk assessment and management.


• Risk assessment is a very broad and deep subject; each topic covered in this course could easily be the subject of a full course of its own.

• As such, this should be considered a course introducing students to the major elements of risk assessment.


• Note also that we will not be going very deep into the technical aspects of risk assessment.

• Students with professional experience in this area are encouraged to share their experience with the class when it is relevant to the topics being covered.


Explanation: • Risk assessment consists of an objective

evaluation of risk in which assumptions and uncertainties are clearly considered and presented.

• Part of the difficulty in risk management is that

measurement of both of the quantities in which risk assessment is concerned - potential loss and probability of occurrence - can be very difficult to measure.


• The chance of error in measuring these two concepts is large.

• Risk with a large potential loss and a low

probability of occurring is often treated differently from one with a low potential loss and a high likelihood of occurring.


• In theory, both are of nearly equal priority, but in practice it can be very difficult to manage when faced with the scarcity of resources, especially time, in which to conduct the risk management process.


Risk assessment in public health

• In the context of public health, risk assessment is the process of quantifying the probability of a harmful effect to individuals or populations from certain human activities.


• In most countries the use of specific chemicals or the operations of specific facilities (e.g. power plants, manufacturing plants) is not allowed unless it can be shown that they do not increase the risk of death or illness above a specific threshold.


• For example, the American Food and Drug Administration (FDA) regulates food safety through risk assessment.

• The FDA required in 1973 that cancer-causing compounds must not be present in meat at concentrations that would cause a cancer risk greater than 1 in a million lifetimes.


• The US Environmental Protection Agency (EPA) provides basic information about environmental risk assessments for the public via its risk assessment portal.


• All required readings will be available as journal articles through the University of Toronto libraries or will be provided throughout the course.
