Title: ENVIRONMENTAL ASSESSMENT EA PRINCIPLES
1ENVIRONMENTAL ASSESSMENT (EA) PRINCIPLES
PRACTICES
- ... plan, predict, follow-up
2ENVIRONMENTAL ASSESSMENT (EA)
- EA implies determination of environmental
consequences or impact of proposed projects or
activities - Impact or effects means change any change,
positive or negative - EA is, therefore, a study of probable changes in
various biophysical and socio-economic
characteristics of the environment which may
result from a proposed or impending action
3RATIONALE FOR EA
- Development can have beneficial and adverse
effects on the environment - Beneficial effects often affect few individuals
and environmental components - Adverse effects often affect many individuals and
environmental components - Development needs to be managed and controlled to
promote beneficial effects and prevent adverse
effects - Environmental assessment is a means to manage and
control adverse effects of development
4BASICS OF EA
- Assess environmental effects of a proposal at
earliest stage in planning - Inform public about the proposal and obtain input
to decision making process - Propose measures to mitigate adverse
environmental effects - Identify follow-up requirements to address
uncertainty - Evaluate significance of residual environmental
effects - Take environmental consequence into consideration
when approving project - Conduct follow-up to determine if assessment is
effective and mitigation is implemented
5EA STEPS
- Basic EA steps
- Develop a complete understanding and clear
definition of the proposed action - Gain a complete understanding the affected
environment - Envision implementation of the proposed action in
that setting and determine possible effects on
the environmental characteristics - Propose measures to mitigate adverse effects and
evaluate significance of residual effects - Prepare a report on the assessment in a manner
that the information may be used in decision
making
6PURPOSE OF EA
- Basic EA objectives are to
- 1. Consider environmental effects at the
project planning and decision making stage - 2. Anticipate and avoid, minimize or offset
adverse biophysical and other effects of
proposals - 3. Support protection of productive capacity
of natural systems and processes - 4. Provide opportunities for public to be
informed and participate in the decision making
process - 5. Promote development that is sustainable and
optimize resource management opportunities
7BENEFITS OF EA
- Provide for environmental protection
- Preserve or enhance quality of life
- Foster sustainable development
- Compliance with legislation
- Public awareness / acceptance / appreciation
- Multidisciplinary integration
- Reduced surprises / anticipate issues
- On-budget / on-time projects - lower costs?
- Improved professional credibility
- Reduced legal liability (due diligence)
- Others
8HISTORICAL EVENTS
- 1950s assessments of major projects for health
and safety - separate documents for major
projects - 1960s public concern recognized as part of
assessment process for projects with significant
effects - 1970s Environmental Assessment and Review
Process (EARP) Policy Berger Inquiry - Mackenzie
Valley Pipeline - 1980s Rafferty-Alameda and Oldman court
decisions EARP interpreted as a legal
requirement and applied to federal jurisdiction
Brundtland Commission - emphasis on prior
environmental assessment of proposed projects
sustainable development - 1990s Canadian EA legislation - new age in EA,
global, sophistication, sustainable development,
strategic environmental assessment, cumulative
effects assessment, transboundary issues
9EA PRE-1970s
- Project review based on technical engineering and
economic analysis - Limited consideration given to environmental
consequences - Assessments carried out to ensure that health and
safety is adequately protected - No commitment for public consultation
- Separate documents submitted
to each regulatory agency
10EA EARLY to MID-1970s
- Environmental assessment introduced
- Basic principles, guidelines, procedures
including public participation - Requirements instituted
- Standard methods for impact analysis developed
- Several countries adopt NEPA-based approach
- Canada adopts a policy-based approach
- Major public inquiries help
shape process development
11EA LATER 1970s to EARLY 1980s
- More formalized guidelines
- Use of environmental assessment in developing
countries - SIA and risk analysis used in environmental
assessment process - Greater emphasis on ecological modeling,
prediction and evaluation - Program level EISs prepared in US
- Environmental inquiries in several countries
encompass policy review aspects
12EA LATE 1980s
- Canada pursues reform of EA policy approach
- European Countries directive on EA establishes
basic principles and procedural requirements - Increasing efforts address cumulative effects
- Development of follow-up mechanisms
- Ecosystem and landscape level approaches applied
- World Bank and other international agencies
establish environmental assessment requirements - Environmental assessment increasing in developing
countries
13EA 1990s to PRESENT
- Canada adopts EA legislation
- Requirements to define transboundary effects
under international convention - Environmental assessment identified as
implementing mechanism for UN conventions - SEA systems established by increasing number of
countries - Mediation incorporated into environmental
assessment requirements - Sustainability principles and global issues
receive increased attention - EA a tool to achieve the goal of sustainable
development
14EA TERMINOLOGY
- Environmental effect (individual change)
- Environmental impact (overall change or result)
- Environmental Assessment (EA)
- Environmental Impact Assessment (EIA)
- Environmental Impact Statement (EIS)
- Social Impact Assessment (SIA)
- Strategic Environmental Assessment (SEA)
- Cumulative Effects
Assessment (CEA)
15ENVIRONMENTAL EFFECT vs. IMPACT
- Environmental effect - any change that a project
may cause in the environment - Environmental impact - sum of the effects or
changes that a project may cause in the
environment (overall result) - Impact Sum of the effects
16ENVIRONMENTAL ASSESSMENT (EA)
- systematic process of identifying, predicting,
evaluating and proposing mitigation for adverse
biophysical, socio-economic and other relevant
effects of development proposals or projects
prior to major decisions and commitments being
taken -
- general process term with broad application
- simply stated as the identification of future
consequences of a current or proposed action
17ENVIRONMENTAL IMPACT ASSESSMENT (EIA)
- environmental assessment process applied to a
specific development proposal or project -
- project-specific environmental assessment
18ENVIRONMENTAL IMPACT STATEMENT (EIS)
- Environmental assessment report prepared in
accordance with institutional requirements at the
conclusion of an EIA for a development proposal,
usually for larger projects. - Typically, an EIS is prepared prior to public
hearings or as part of reviews of environmentally
significant projects - Canada - prepared for panel review projects
following guidelines established by the panel - Manitoba - prepared for developments with
potentially significant effects following
guidelines established by the Director, Minister
or CEC
19SOCIAL IMPACT ASSESSMENT
- process of estimating the social, economic and
other relevant consequences that are likely to
follow from specific policy and development
proposals, particularly in the context of
established environmental assessment requirements - can be conducted as part of an EIA
assessment or separately
20STRATEGIC EA (SEA)
- process of prior examination and appraisal of
policies, plans and programs and other higher
level or pre-project initiatives - follows general environmental assessment
procedures at a conceptual level - Canadian policy to assess federal policies, plans
and programs, including budget proposals
21CUMULATIVE EFFECTS ASSESSMENT (CEA)
- incremental effects of a project on the
environment when the effects are combined with
those from other past, present and future
projects - predicts effects of projects are likely to occur
in the reasonably foreseeable future - scope usually has greater spatial and temporal
boundaries - regional land-use
planning scale

Effect may be at all levels but EA is usually
applied at the ecosystem level
25ECOSYSTEM BASIS
- Ecosystem ...
- level of ecological study that includes all
organisms in a given area as well as biotic and
abiotic factors they interact with - community of living and non-living elements
connected through energy flow and nutrient
cycling - retains identity in geographic perspective even
through dynamic shifts may occur in
climatological and geological variables
