Environmental Impact

Assessment (EIA)
Lecture prepared for
Project Management Course
EIA
EIA is a systematic process to identify, predict and
evaluate the environmental effects of proposed
actions and projects.

A broad definition of environment is adopted.
Whenever appropriate social, cultural and health
effects are also considered as an integral part of EIA.

Finally, particular attention is given in EIA for
preventing, mitigating and offsetting the significant
adverse effects of proposed undertakings
Definition
It is a planning and management tool for
sustainable development that seeks to identify the
type, magnitude and probability of environmental
and social changes likely to occur as direct or
indirect result of a project or policy and to design
the possible mitigation procedure (Vanclay and
Bronstein, 1995; Harvey, 1998; Momtaz et al.,
1998; Thomas, 1998).

EIA is a tool that is applied
before major decisions are taken and when all alternatives
are still open;
to inform all stages of decision making, including final
approval and the establishment of conditions for project
implementation;
with public participation and consultation; and
to integrate environmental considerations and safeguards
into all phases of project design, construction and operation
History
The National Environmental Policy Act 1969 of USA is the
legislative basis for EIA. The policy was the result of wide
spread recognition in the 1960s that some major
environmental problems were created by the governments
projects (power stations, dams and reservoirs, industrial
complexes).
The legislation made mandatory to assess the
environmental consequences of all projects by federal
agencies.
In 1990s, many developed and some developing countries
designed their EIA legislation. e.g. New Zealand (1991),
Canada (1995), Australia (1999), Vietnam (1993), Uganda
(1994), Ecuador (1997).
Today, EIA is firmly established in planning process in
many of these countries.

Amendment of EC
Directive on EIA (1997)

Required all member states to be in
compliance by 1999; also assisted in
drafting the EIA laws of transitional
economies who are in the process of
accession to the European Union.
UNECE - Convention on
EIA in a Trans-boundary
Context (1991)
Entered into force in 1997 as the first EIA-
specific international treaty.


Purposes/Aims and Objectives
The immediate aim of EIA is to inform the process of
decision-making by identifying the potentially
significant environmental effects and risks of
development proposals.

Objectives related to this aim are to:
improve the environmental design of the proposal;
ensure that resources are used appropriately and
efficiently;
identify appropriate measures for mitigating the
potential impacts of the proposal; and
facilitate informed decision making, including setting
the environmental terms and conditions for
implementing the proposal.
Purposes/Aims and Objectives (cont.)
The ultimate (long term) aim of EIA is to promote
sustainable development by ensuring that
development proposals do not undermine critical
resource and ecological functions or the well being,
lifestyle and livelihood of the communities and peoples
who depend on them.

Objectives related to this aim are to:
protect human health and safety;
avoid irreversible changes and serious damage to the
environment;
safeguard valued resources, natural areas and
ecosystem components; and
enhance the social aspects of the proposal.
Regions Major Environmental Issues
Africa The continent has the worlds poorest and most resource dependent
population. It carries the highest health burden due to severe
environmental problems. These include desertification and soil
degradation, declining food security, and increasing water scarcity.
Asia and
Pacific
Rapid economic growth, urbanization and industrialization have
helped in poverty alleviation but also increased pressure on land and
water resources, widespread environmental degradation and high
pollution levels. Mega- cities are a particular focus of environmental
and health concerns.
Eastern
Europe and
Central Asia
Despite progress with economic restructuring and environmental
clean up, there is a legacy of industrial pollution and contaminated
land during communist era. In many areas, emissions of particulates,
SO2, lead, heavy metals and toxic chemicals continue to expose the
residents to health risks, and, in the Balkans, war and regional
conflict have exacted a heavy environmental and social toll.
Latin
America
and the
Caribbean
Approximately three-quarters of the population live in urban areas.
Many cities are poor, overcrowded, polluted and lack basic
infrastructure. The major environmental issue is the destruction of
tropical forests and consequent loss of biodiversity, which is
especially serious in the Amazon basin.
Steps in EIA
*Public involvement typically
occurs at t hese point s.
It may also occur at any
ot her st age of t he EIA Process

Step 1: Screening
This step determines:
whether or not EIA is required for a particular
project
what level of EIA is required

Screening Outcomes:
Full or comprehensive EIA required
Limited EIA required
No EIA required

Tools for Screening
Project lists:
Inclusive listed projects must undergo EIA
Exclusive listed projects exempted from EIA

Case-by-case examinations:
determine whether projects may have significant
environmental effects
if so, project should undergo EIA

Combination of above
Mandatory EIA

EIA ruled out
Inclusive threshold
Indicative threshold
Exclusive threshold
Screening Process
Step 2: Scoping
begins once screening is completed
the most important step in EIA
establishes the content and scope of an EIA report

Outcome:
identifies key issues and impacts to be considered
lays the foundation of an effective process, saves time
and money, and reduces conflict
Types of Scoping
Closed scoping:
wherein the content and scope of an EIA Report is
pre-determined by law and modified through closed
consultations between a developer and the
competent authority
Open or Public scoping:
a transparent process based on public consultations
Actors
proponent, EIA consultant, supervisory authority
for EIA, other responsible agencies, affected public
and interested public
The scoping process
prepare a scope outline
develop the outline
through informal
consultation with
environmental and
health authorities
make the outline
available
compile an extensive list
of concerns
evaluate relevant
concerns to establish
key issues
organise key issues into
impact categories (study
list)
amend the outline
accordingly
develop Terms of
reference (ToR) for
impact analysis
monitor progress
against the ToR, revising
as necessary

Step 5: Reporting
Different name of EIA reports
Environmental Impact Assessment Report (EIA
Report)
Environmental Impact Statement (EIS)
Environmental Statement (ES)
Environmental Assessment Report (EA Report)
Environmental Effects Statement (EES)
Contents of the Report
a description of the project;
an outline of the main alternatives studied by the developer,
and an indication of the main reasons for this choice,
a description of the aspects of the environment likely to be
significantly affected by the proposed project;
a description of the likely significant environmental effects
of the proposed project;
measures to prevent, reduce and possibly offset adverse
environmental effects;
a non-technical summary;
an indication of any difficulties (technical deficiencies or
lack of know-how) encountered while compiling the
required information.
Step 6: Review
Review the quality of the EIA report.
Take public comments into account.
Determine if the information is sufficient.
Identify any deficiencies to be corrected.

Who Perform the review?
environmental agency Canada (comprehensive
studies), standing commission Netherlands, inter-
agency committee USA, planning authority UK
independent panel Canada (public inquiries)
Public comment and input
Step 7: Decision Making
To provide key input to help determine if a proposal is
acceptable

To help establish environmental terms and conditions
for project implementation
Step 8: Monitoring
Ensure the implementation of conditions attached to a
decision.
Verify that impacts are as predicted or permitted.
Confirm that mitigation measures are working as
expected.
Take action to manage any unforeseen changes.
Key components of Monitoring
Establish baseline conditions.
Measure impacts of a project as constructed.
Verify conformity with established with conditions
and acceptable limits.
Establish links to environmental management plans.
Carry out periodic checks and third-party audits.
To ensure that significant issues are identified; project
related information is gathered, alternatives are considered.
To avoid biases/inaccuracies in analysis; identify local
values/preferences; assist in consideration of mitigation
measures; select best alternative.
To consider and comment on EIA Report
To monitor the implementation of EIA Reports
recommendations and decisions conditions.
To consult people likely to be affected by proposal.
