ENVIRONMENTAL IMPACT
ASSESSMENT

Environmental Impact
Assessment
• Industries create large amounts of pollution and
deplete natural resources like ground water.
• In the past, polluting industries were set up without
any environmental clearance by the government.
• Therefore they caused huge environmental
damages, affecting ecology and health.
• To avoid this, it is now necessary for every new
factory/project to get environmental clearance
before starting production.

Definition
• Environmental Impact Assessment or
EIA, refers to the evaluation of the
effects likely to arise from a major
project or action, significantly affecting
the natural and man-made
environment.
– It is the process of predicting and
evaluating an action’s or project’s impact
on the environment, so as to assist
decision making.

4. 4
– It aims to prevent environmental
degradation by giving decision makers
better information about the
consequences that industrial projects
could have on the environment.
– All new development projects have to
submit their EIA reports to the
Environmental Ministry of the country, to
get environmental or green clearance to
commence production.

5. – EIA helps to identify possible environmental effects
of the proposed project,
– It proposes measures to mitigate adverse effects and
– Predicts whether there will be significant adverse
environmental effects, even after the mitigation is
implemented.
ADVANTAGES OF EIA:
• Since the environmental effects of the project
and their mitigation are considered early in the
project planning cycle, protection of the
environment can be a part of the project plan.
• Also it predicts ways to use natural resources
(like water), in an optimal way.

6. • Thus leading to saving of time and cost of the
project
• It also lessens conflicts between the
industry/project and the local community, by
sharing information about environmental
impacts, and involving the latter in decision
making.
• EIA also aims at informing decision makers, and
helps to lay the base for environmentally sound
projects.
• These are the benefits of integrating EIA in all
stages of a project, from exploration and
planning, through construction, operations,
decommissioning, and beyond site closure.

7. 7
• Thus the EIA is a) Anticipatory, b)Participatory,
and c) the project can be abandoned if
environmental impact is high.
• In all the stages, it is necessary to have public
participation, as the local people are greatly
affected by the environmental damages caused
by a project/ factory.
• For example:
– Hydro electric, thermal, and nuclear projects,
– Pharmaceuticals, chemicals, fertilisers,
pesticide factories.

8. • EIA as a mandatory regulatory procedure originated in
USA, in the early 1970s.
• Other countries, like Canada, Australia, and New
Zealand (1973-74), followed.
• Some developing countries such as Columbia (1974),
Philippines (1978), also introduced EIA in the 70’s.
• In India:
– The Government of India introduced EIA in 1994,
under the Environmental (Protection) Act of 1986,
– Environmental Clearance (EC) was made mandatory
for expansion or modernisation of any activity or for
setting up new projects listed in Schedule 1 of the
notification.

Origins of EIA
25-11-2014 Prabha Panth

9. – New EIA legislation was introduced in
September 2006.
– Mandatory for various projects such as
mining, thermal power plants, river valley,
infrastructure (road, highway, ports,
harbours and airports) and industries
including very small electroplating or foundry
units.
– Project clearance to be given by State
governments, depending on the
size/capacity of the project.
– Donor agencies operating in India like the
World Bank and the ADB, also insist on
environmental clearance to projects funded

Objectives of EIA
1) Information: It has to disclose to decision
makers and the public the environmental
impacts of the proposed activity.
2) Avoidance/Reduction: Identify ways of
reducing or avoiding environmental effects
of the project.
3) Participation: Public should be made
aware of the environmental impacts, and
their participation is necessary in decision
making. Because the locals are the first to
feel the environmental impacts.

Elements of EIA
1. Alternatives: Most important part of EIA.
The project manager should give
alternatives regarding:
a) Locations for the project
b) Different and less polluting/ damaging
available technology
c) Different available product – less polluting/
damaging.
The choice of the alternative should be that
which has the least environmental impact.
25-11-2014 Prabha Panth

12. 2. Designing: of the selected project – so as
to have least environmental impact.
3. Screening: to decide which of the
project’s processes and products requires
EIA.
4. Scoping: To determine the scope of the
EIA – whether it will affect air, water, soil,
or cause noise, vibration, fumes, etc.
5. EIA Report: also called EIS or
Environmental Report Statement – to be
prepared and submitted to the
government for its scrutiny. On the basis
of EIS the government will accept or reject
the project proposal.

13. 6) Reviewing: the EIA Report has to be
reviewed by both the Government and the
public.
7) Consultancy: and participation of the
public is required. If the people feel that
they are threatened by the project, they
can reject it setting up in their locality.
8) Monitoring: If the project is passed, then
government should keep monitoring it
continuously to ensure that it is following
all the environmental laws and regulations.

14. EIA in India
• EIA was introduced in India in late 70s as an
administrative requirement.
• As per EIA Notification 1994: 32 Categories of Projects/
Processes require environmental clearance.
• Project level EIAs are practiced in India.
EIA Notification 2006. Objectives:
To formulate a transparent decentralized and efficient regulatory
mechanism to:
• Incorporate necessary environmental safeguards at planning stage;
• Involve stakeholders in the Public Consultation Process;
• Identify Developmental Projects based on Impact Potential instead
of the investment criteria.
• Categorization of projects into ‘A and ‘B’ Category based on impact
potential

15. • 60 days for prescribing TOR (terms of reference)
• 45 days for completing Public Hearing
• 105 days -- Environmental Appraisal and communicating
the decision.
Weakness of EIA in India:
• Quality of EIA Reports
• Monitoring and Compliance of EC Conditions
• Availability of reliable environmental data base
• Technical manpower for EIA Process
• Technology evaluation for mitigation.
• Corruption and bribery.
Environmentally unsafe projects are still being permitted.
25-11-2014 Prabha Panth 15

16. Cases in India
• EIA reports prepared by so called ‘experts’, there is large
scale misrepresentation of environmental impacts of the
projects.
• For example, a bauxite mining firm in Maharashtra gave
an EIA report based on EIA of some Russian firm!
• An EIA report of a river valley project in Karnataka, gave
data of another project thousands of miles away.
• Well known institutes like NEERI (Karcham Wangtoo
hydropower project of Himachal Pradesh) and TERI
(Dandeli hydropower project in Karnataka) submit false
data in their reports.
• Only through NGOs, agitations by locals, and Court
orders, environmental laws being somewhat implemented
in India.
