Environmental Impact
Assessment
Prepared by
Dr. Siraj M.A. Goran

EIA (Environmental Impact Assessment)
 EIA is a systematic process to identify, predict and
evaluate the environmental effects of proposed
actions and projects on the environment.
 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
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.

 EIA acts as a Practical Solutions for
Problems) as:
 ∗ Determining and managing (identifying,
describing, measuring, predicting,
interpreting, integrating, communicating,
involving and controlling),

 ∗ Potential (or real) impacts (direct and
indirect, cumulative, likelihood)
 ∗ Proposed (or existing) human actions
(projects, plans, programs, legislation, activities)
and their alternatives on the environment,
Environment (Physical, Chemical, biological,
human health, cultural, social, economic, built
and interactions)”

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;
 public participation and consultation; and
 to integrate environmental considerations
and safeguards into all phases of project
design, construction and operation

Environment will cover, the existing
condition in or/and around the area is as
much as:
 (i) Physical environment to include:
 (a) Land and Climate: Weather conditions to include
temperature (ambient), humidity, wind velocity,
precipitation, land use, topography, geology and
seismic considerations.
 (b) Atmospheric conditions: Ambient air quality at
the site and around specially in down wind direction
 (c) Water bodies: Laks, rivers, ponds and canals.
Hydrology and existing quality. Ground water
availability and flow regime
 (d) Noise level

 (ii) Chemical Environment to include:
 (a) Industrial activities, types of industries at
the site and around (10 km radius), types of
wastes produced and methods of treatment
and disposal of effluents.
 (b) City dumping sites, land fill sites

 (iii) Infrastructure: Public Services, Water
Supply, Waste Treatment Plants, Energy
resources, distribution system, Transport
system, communication, important buildings,
heritage, sites etc.
 (iv) Biological environment: Vegetation,
forests, flora, fauna. Natural vegetation,
parks, cultivated land, crops, threatened and
endangered species.

 Before 1960, seldom environmental factors
considered in economic equation.

 Environment is a comprehensive term meaning
surroundings. It includes the gaseous envelope
surrounding earth, the Atmosphere, the mass of
water above and below the earth, the
Hydrosphere, the land masses that support life,
the Lithosphere, and the whole microbes,
plants, and animals, collectively referred as,
Biosphere.

 Man is often said to be his own enemy.
This is perhaps true in the consequence of
human activities to provide food, shelter,
amenities (characters) and transport.
While products of industry and agriculture
make human existence more bearable and
pleasant, they give rise to waste effluents
and emissions.

Some of the interactions of human
existence relate to:
 - utilization of a resource without impairing its
use,
 - disposal of wastes without creating problems,
 - degradation of forest wealth and exploitation
of biota

 The rapid growth of population, improvements
in standards of living and concomitant growth
of infrastructure have altered the environment,
sometimes beyond its power of resilience.
These changes have resulted in
ecological crisis and have become a
matter of grave concern to managers and
decision makers throughout the world.
The issues both at national and global levels are
focussing concern of nodal agencies (to support
sustainable development and tend to produce
adverse impacts on living conditions of
human, animals, plants and geographical
environment.

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 government’s 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.

Purposes/Aims and Objectives
 Environmental impact assessment is an important
management tool for improving the long-term viability
of projects. Its use can help to avoid mistakes that can
be expensive and damaging in environmental, social
and economic terms. Human activities are altering
natural cycles and systems on an unprecedented scale,
and the cumulative effects of these activities are
estimated to be on part with bio-physical processes as an
agent of ecological change.

 Usually, the cost of undertaking an EIA
accounts for only a small proportion of
total project costs (usually less than
0.1% of overall project costs), but
savings to the project from an impact
assessment can often considerably more.

 More broadly, EIA is used for early warning
planning of a wide range of resource use,
development, and conservation initiatives in
order to make the most of options for
achieving sustainability.
 We live in a greenhouse world of ozone
holes and vanishing (disappear) species. It
is now considered that the impact of human
activities on the biosphere is reaching
critical thresholds, with the consequent
threat of ecological breakdown and social
conflict.

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.

The ultimate (long term) aim of EIA is to promote
sustainable development by ensuring that development
proposals do not undermine (destroy) 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.

*Public involvement typically
occurs at these points.
It may also occur at any
other stage of the EIA Process

Step 1: Screening
 This step determines:
• whether or not EIA is required for a particular
project
• what level of EIA is required (Level A, B, C)
 Screening Outcomes:
 Full or comprehensive EIA required
 Limited EIA required
 No EIA required

Tools for Screening
 Project lists:
• Inclusive (Comprehensive) — 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

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 (Propose person), 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 (collect) an
extensive list of
concerns
 evaluate relevant
concerns to establish key
issues
 organise key issues into
impact categories (study
list)
 amend (improve) the
outline accordingly
 develop ‘Terms of
reference’ (ToR) for
impact analysis
 monitor progress against
the ToR, revising as
necessary

(SCOPING)

Step 3: Impact Analysis
→ Type biophysical, social, health or economic
→ Nature direct or indirect, cumulative, etc.
→ Magnitude or
severity
high, moderate, low
→ Extent local, regional, trans-boundary or global
→ Timing immediate/long term
→ Duration temporary/permanent
→ Uncertainty low likelihood/high probability
→ Reversibility reversible/irreversible
→ Significance* unimportant/important

Tools for Impact Analysis
 checklists
 matrices
 networks
 overlays and geographical information systems (GIS)
 expert systems
 professional judgement

Step 4: Impact Mitigation
 to avoid, minimise or remedy adverse
impacts
 to ensure that residual impacts are
within acceptable levels
 to enhance environmental and social
benefits

Framework for Impact Mitigation
Common (desirable)
Rare (undesirable)
Alternative sites or
technology to
eliminate habitat loss
Actions during
design, construction and
operation to minimise
or eliminate habitat
loss
Used as a last resort
to of
fset habitat loss
Avoidance
Mitigation
Compensation

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
 1-Executive summery (a non-technical summary)
 2-International and national Regulations and law
 3-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,

• 4-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;
• 5-Measures to prevent, reduce and possibly offset
adverse environmental effects (Mitigation measure)
• An indication of any difficulties (technical deficiencies
or lack of know-how) encountered while compiling the
required information.

 6-Environmental Baseline study
 Environmental baseline sampling
7-Waste Management Plan
8-Environmental management and monitoring
Plan
9-Emergency and preparedness
10-Conclusions
11-References

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 of EIA report in Kurdistan and around
the world?
 In Kurdistan, MNR (Ministry of natural resources), Environmental
committee for protection and improvement for KRG, environmental
agency — Canada (comprehensive studies), standing commission —
Netherlands, inter-agency committee — USA, planning authority — UK
independent panel — (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 Report’s
recommendations and decision’s conditions.
To consult people likely to be affected by proposal.
