3. The Defination of EIA
Environmental Impact Assessment (EIA) refers to the evaluation of the environmental
impacts likely to raise from a major project significantly affecting the environment.

5. Impact
1. The impact of an activity is a deviation (a change) from
the baseline situation that is caused by the activity.
2. The baseline situation is the existing environmental
situation or condition in the absence of the activity.

6. Types of Impacts
1.Ecological Impact
Fisheries, forests.plantation, eutrophication
2.Physico-chemical Impact
Erosion and Siltation, drainage congestion /water logging. regional
hydrology/flooding, obstruction to waste water flow, dust /noise pollution.
3.Impact on Human Interest
Loss of agricultural lands, generation of employment opportunities,
navigation and boat communication, commercial and service facilities,
industrial activities, irrigation facilities.

7. Historical Background of EIA
► EIA was first developed in the US as a result of the
National Environmental Policy Act of 1969(NEPA),
for considering possible impacts prior to a
decision being taken on whether or not a proposal
should be given approval to proceed

8. Purpose of EIA
► Identification,
estimation and
assessment of
important
effects that the
planned project
may have on the
environment.
► Presentation of
data on impacts
in the report for
the authorities
responsible for
approving the
realization of the
project, as well as
for the public,
Encouragement
of authorities
responsible for
approving the
planned projects
to include

9. Objectives of EIA
1. To ensure that eventual effects on the environment are considered before the
approval of project
2. To encourage implementation of relevant procedures before finalizing the
project.
3. To encourage the creation of procedures for information exchange, reporting
and consultation amongst countries

12. THE PR0CESS INCLUDES FOLLOWING
STEPS:
1. Screening
2. Scoping
3. Impact analysis
4. Reporting
5. Review
6. Decision making
7. Monitoring

13. 1. SCREENING
► The screening process determines whether a particular project requires
preparation of an EIA or not.

14. 2. SCOPING
► Scoping is a stage, usually involving the public and other interested parties,
that identifies the key environmental issues that should be addressed in an
EIA.

15. 3. IMPACT ANALYSIS
► The type, extent, duration, timing, severity and significance of the impact is
analyzed.

16. 4. IMPACT MITIGATION
► Ensuring that residual impacts are within acceptable levels and to enhance
environmental and social benefits.
► It is the implementation of measures designed to reduce the undesirable
effects of a proposed action on the environment.

17. 5. REPORTING
► Report of EIA is prepared and submitted to the concerned authority
CONTENTS OF REPORT
1. A description of the project.
2. An outline of the main alternatives studied by the developer, and an indication of
the main reasons for this choice.
3. A description of the aspects of the environment likely to be significantly affected by
the proposed project.
4. A description of the likely significant environmental effects of the proposed
project.
5. Measures to prevent, reduce and possibly offset adverse environmental effects.
6. Anon-technical summary.
7. An indication of any difficulties (technical deficiencies or lack of know-how)
encountered while compiling the required information.

18. 6.REVIEW
► In this step, the report is studied thoroughly for any deficiencies and
corrections are made. Public participations is the important part of this step.

19. 7. DECISION MAKING
► Involves deciding whether the project is acceptable or not. The terms and
conditions are finalized in this step.

20. 8. MONITORING
► Involves ensuring the implementation of conditions attached to a decision,
verification of impacts are as predicted or permitted, confirming the
mitigation measures are working as expected, taking action to manage any
unforeseen changes.

21. WHERE IS EIA REQUIRED?
1. For schedule 1 projects, carrying out ELA is MUST.
2. For schedule 2 projects, EIA must be carried out if the development is likely
to have a significant impact on the environment by virtue of its nature, size
or location.

22. SCHEDULE 1 PROJECTS
1. Major power plants
2. Chemical works
3. Waste disposal incineration
4. Major Roads Schemes

23. SCHEDULE 2 PROJECTS
1. Quarries and opencast
2. Some intensive livestock rearing
3. Overhead transmission lines
4. Surface storage of fossil fuel
5. Foundries and forges
6. Coke ovens
7. Manufacture of dairy products
8. Brewing
9. Some textile operations
10. Rubber production
11. Wide range of infrastructure projects
12. Waste water treatment plants
13. Holiday villages
14. Golf courses

24. Uses of EIA
1. Systematic evaluation of a eco friendly project.
2. Risk and hazard assessment.
3. Impact Identification.
4. Monitoring of impact and advice.
5. Development control.
6. Project development
7. SEA (strategic environmental assessment) and permit.

25. Conclusion
1. EIA is an important tool in assuring that projects and plans will not give an
adverse impact on the environment.
2. It improves the environmental design of the proposal.
3. Ensure that resources are used appropriately and efficiently.
4. Identifies appropriate measures for mitigating the potential impacts of the
proposal.
5. Facilitate informed decision making, including setting the environmental
terms and conditions for implementing the proposal.
