INTRODUCTION
Environmental Impact Assessment (EIA) is a process which
ensures that all environmental matters are taken into account
quite early in the project at planning process itself.
It takes into consideration not only technical and economic
considerations but also, traditional aspects like impact on
local people, biodiversity etc.
EIA is intended to prevent or minimize potentially
adverse environmental impacts and enhance the
overall quality of a project. The main benefits
and advantages of EIA are:
Lower project costs in the long-term
Increased project acceptance
Improved project design
WHY EIA?
The EIA Directive requires projects likely to
have significant effects on the Environment
by virtue of their nature, size or location to
undergo an environmental assessment before
the competent authority in question grants
consent.
The EIA Directive defines a project as the
execution of construction works or of other
installations or schemes,
other interventions in the natural
surroundings and landscape including those
involving the extraction of mineral resources.
THE EIA DIRECTIVE
The EIA should identify, describe and assess
the direct and indirect effects of a project on
the following factors:
Human beings
Fauna and flora
Soil, Water & Air
Climate and the landscape
Material Assets
Cultural Heritage
Interaction between all above factors
EIA therefore should have a very strong social
dimension
Started in 1976-77, when Planning Commission asked
Department of Science & Technology to examine River
Valley Projects from environmental angle
Till 1994, Environmental Clearance from Central
Government was an administrative decision which lacked
legislative support.
On 27th
January 1994, Union Ministry of Environment &
Forests, GOI under Environment (Protection) Act 1986,
promulgated EIA notification making Environment
clearance mandatory for expansion or modernization of
any activity or for setting up new projects listed in
Schedule one of the notification, which have been
amended more than 12 times.
HISTORY OF EIA IN INDIA

PROJECTS UNDERGOING EIA
Environment Impact Assessment
EIA Clearance required
Total EIA clearance is required for 32 categories of developmental
works broadly categorized into following industrial sectors:
Mining
Thermal power plant
River valley
Infrastructure (Road, highway, ports, harbour, airports,
Industries including very small electroplating or foundry units)
Certain activities permissible under Coastal Regulation Zone Act 1991,
also require similar clearance

Screening
• It would be time consuming and a waste of
resources for all proposed projects and activities
to undergo EIA
• Not all development projects require an EIA, as
some projects may not pose an environmental
threat
• Screening is the process used to determine
whether a proposed project or activity requires
an EIA and, if so, what level of environmental
review is necessary.

Prepare the work plan for the initial
environmental examination (IEE)
Project type on project

Get specific IAA

Project scale above the

Project located in a critical
area?
IAA funding, or any other
special circumstances?
NO

Initial Environment Examination
Environment Examination
 Initial environmental examination (IEE) is
intended as a low-cost environmental evaluation
that makes use of information already available.
It boost up the process of EIA and lead the
matter to further assistance.
IEE in the Overall EIA Process
Project
Screening
Identifies projects that
typically contain potential
significant issues
Initial Environmental Examination
1. Identifies potential significant
environmental issues associated
with a project
2. Grades effects and identifies actual
Significant Environmental Issues
(SEIs)
3. Resolves simple SEIs
4. Recommends further action for
resolving outstanding SEIs
Full-Scale EIA or Other
Additional Study
Resolves any remaining
significant environmental issues
Scoping
 A process of interaction between government
agencies and project proponents
 Identifies:
– spatial and temporal boundaries for the EIA
– important issues and concern
– information necessary for decision making
– significant effects and factors to be considered
– Establishes terms for reference of full scale

Assessment phase:
– Qualitative/quantitative analysis of SEI
– SEI impact significance
Mitigation development phase:
– Select appropriate mitigation measures
– Residual impact significance

 Checklists
 Matrices
 Risk Assessment
 Network
 Overlays/GIS
 Expert Systems
 Risk assessment
Decision Making
• The challenge of making the final decision on
implementing a project is observed.
• Decision are taken at all stages during the EIA
process and the outcome will be based on these
decisions.
• If a large scale project falls under the jurisdiction
of countries with comparable national EIA
procedures,it should be feasible to be more
ambitious in organising EIA Transboundary..
Monitoring
 In legislation there is a often demand for
environmental reporting when treating
permits to activities with large EIA.
 This stage involves improvement and
mitigational measures to put forward EIA.
 It also involves elements of assessing
risks and hazard management.
Audit and Evaluation
• This is the final stage of EIA.
• Audit consists opinions and corrections of
the report which are submitted in front of
decision making committee.
• It also reveals that whether EIA is
necessary or not for the report submitted,if
necessary what are the measures taken in
order to overcome the drawbacks and
hazards..
Uses of EIA
 Systematic evaluation of a eco friendly
project.
 Risk and hazard assessment.
 Impact identification.
 Monitoring of impact and advice.
 Development control
 Project development
 SEA(strategic environmental
assessment) and permit.
CONCLUSION
 EIA is an important tool in assuring that
projects and plans will not give adverse
impact on the environment.
 The use of EIA has developed
throughout the world and may different
applications exists.
 EIA process thus could not only prevent
costs due to environmental aspects but also
prevent possible public opinions and protest
against a project.
