INTRODUCTION:
The EIA process should identify the same environmental values and propose the same
environmental protection commitments that would be found in the environmental assessment but
an EIA typically goes into greater detail. The EIA is used by the proponent to develop their
proposal, inform the public and interested parties, and to help establish recommended conditions
for approvals.
CONCEPT OF EIA:
According to UNEP, Environmental Impact Assessment (EIA) is a process of evaluating the
likely environmental impacts of a proposed project or development, taking into account inter-
related socio-economic, cultural and human-health impacts, both beneficial and adverse.
According to Eccleston (2011), Environmental Impact assessment (EIA) is the assessment of
the environmental consequences (positive and negative) of a plan, policy, program, or actual
projects prior to the decision to move forward with the proposed action. In this context, the term
"environmental impact assessment" (EIA) is usually used when applied to actual projects by
individuals or companies and the term "strategic environmental assessment" (SEA) applies to
policies, plans and programmes most often proposed by organs of state. Environmental
assessments may be governed by rules of administrative procedure regarding public participation
and documentation of decision making, and may be subject to judicial review.
HISTORY OF EIA:
Environmental impact assessments commenced in the 1960s, as part of increasing environmental
awareness. EIAs involved a technical evaluation intended to contribute to more objective
decision making. In the United States, environmental impact assessments obtained formal status
in 1969, with enactment of the National Environmental Policy Act. EIAs have been used
increasingly around the world. The number of "Environmental Assessments" filed every year
"has vastly overtaken the number of more rigorous Environmental Impact Statements (EIS)."
(Clark & Canter 1997). An Environmental Assessment is a "mini-EIS designed to provide
sufficient information to allow the agency to decide whether the preparation of a full-blown
Environmental Impact Statement (EIS) is necessary."( Rychlak & Case, 2010) EIA is an activity
that is done to find out the impact that would be done before development will occur (Kershner,
2011).
The development of EIA stages are-
2
Beginning of the system: US was the first country to develop a system of
environmental impactassessment (EIA). When “Silent Spring” written by Rachel
Carson was published in 1962, social awareness to environmental issues in the US had
reached high proportions and grew as very intense movements at the latter half of 1960’s.
It obtained formal status in USA with the implementation of National Environment
Policy Act (NEPA) in 1969.
International Efforts: Several International Organization started working on EIA
afterwards. Such as-
i. UNEP (United Nations Environmental Programme): Activities of the
United Nations began in 1982, with the adoption of World Charter for
Nature at the United Nations General Assembly.
ii. OECD (Organization for Economic Cooperation and Development):
The OECD “Declaration on Environmental Policy” (1974) was the first
international document to incorporate EIA.
Development Assistance Agencies: Several agencies started working on financial
support for developing the EIA programme, e.g. - The World Bank (WB) is an exponent
multilateral development bank that provides loan and finance to the developing countries
and development assistance projects. The World Bank’s “Environmental Policy and
Procedures” adopted in 1984 stated the integration of environmental consideration at the
initial stages of defining and preparation of a project. Also Japan International
Cooperation Agency (JICA) (1988) and Japan Bank for International Cooperation
(JBIC) (1997) joined the programme.
Adapting EIA in different countries: Different countries have adopted EIA with its
progress and development. Such as-

EIA DVELOPMENT IN BANGLADESH:
Bangladesh initiated environmental impact assessment (EIA) guidelines in 1992 for the water
sector development. The country enacted EIA legislation in 1995 and EIA rules in 1997. Today,
all major donor agencies working in Bangladesh have their own EIA guidelines (Momtaz, 2001).
In the early and mid 1980s, EIA in Bangladesh was mainly donor driven. In the time,
environmental issues started to be seen as much more linked to broader development issues and
became institutionalized in 1989 with the establishment of the present Ministry of Environment
and Forestry. In line with the general recommendations of the Rio Earth Summit, The National
Environmental Policy was framed in 1992. This policy required EIA for all new public and
private projects. In 1993, the National Environmental Committee headed by the Prime Minister
was formed to address environmental issues at the central level. Several guidelines were
prepared in 1990s. Key of these guidelines included: Guidelines on Environmental Issues
Related to Physical planning in 1992 and Guidelines for Physical Planning of Rural Areas in
Bangladesh in1995. These are said to have had little influence on EIA thus ultimately, the
Environmental Conservation Act (1995) and the Environmental Conservation Rules (1997) gave
formal status to EIA in Bangladesh. Thereafter, the EIA system had been further developed
through amendments of the Act and the Rules and the issuance of the Environmental Court Act
in 2000 (Harvey and Ahmed, 2004).
Legislative bases for EIA in Bangladesh are the Environmental Conservation Act 1995 (ECA
’95) and the Environmental Conservation Rules 1997 (ECR ’97). DOE, under the Ministry of
Environment and Forest, is the regulatory body responsible for enforcing the ECA ’95 and ECR
’97 (BCAS, 1999). During the decades of 1970 and 1980, the government of Bangladesh, with a
view to alleviating poverty and resolving the country’s unemployment problem, resorted to many
industrial and agricultural development projects. Much of these development activities took
place without paying any attention to their environmental consequences. As a result, the country
suffered from environmental degradation in many areas.
One burning example is the large-scale contamination of groundwater by arsenic. However, there
is a recent realization that development could not be sustained if due consideration was not given
to environmental protection. Consequently, the government of Bangladesh, with the view of
providing for the conservation and improvement of environmental quality and controlling and
mitigating pollution in the environment, enacted the ECA ’95, which became effective on June 1,
1995. Section 12 of this Act stipulates that ‘‘No industrial unit or project shall be established or
undertaken without obtaining environmental clearance from the Director General, DOE, in the
manner prescribed by the rules’’ (DOE, 1997, p. 1). Clause (2) (f) of Section 20 requires that
rules be made to ‘‘evaluate, review the EIA of various projects and activities, and procedures be
established for approval’’ (BCAS, 1999, p. 43).

IMPORTANCE AND IMPLICATION SECTOR OF EIA:
Importance: The EIA provides the following benefits:
It creates an opportunity for public participation.
EIA increases protection of human health.
EIA ensures the sustainable use of natural resources.
It reduces project costs and delays.
EIA minimizes risks of environmental disasters.
EIA ensures the government responsibility to the project.
It creates alternatives and mitigating impacts.
EIA helps to conserve biodiversity.
EIA ensures the reduction of environmental pollutions.
It helps to eradicate the harmful pollutants originated due to a project.
EIA combines the sustainable development process and environmental protection.
EIA helps to originate a balanced environment between industries and settlements.
EIA defines the necessity or obsoleteness of a project.
It prohibits the inappropriate steps taken for sustainable development.
EIA ensures environmental sustainability.
Implications sectors of EIA: Environmental Impact Assessment (EIA) is a key aspect of most
large scale development projects and remains an integral part of our planning system. Ever
evolving legislation and case law continues to make EIA a key area for those wishing to
challenge planning decisions, so it is an important part of planning to get right. EIA can be
applied to any sector regarding the sustainable development and planning. Such as-
1. Environmental Sector
2. Ecological Sector
3. Agricultural Sector
4. Environmental Economic Sector
5. Energy Sector
6. Manufacturing Sector
7. Technology Sector
8. Transport Sector
9. Business Sector
10. Income Sector
11. Architecture Sector
12. Politics Sector
13. Culture Sector

PROCESSES AND STEPS OF EIA:
The EIA process makes sure that environmental issues are raised when a project or plan is first
discussed and that all concerns are addressed as a project gains momentum through to
implementation. Recommendations made by the EIA may necessitate the redesign of some
project components, require further studies, and suggest changes which alter the economic
viability of the project or cause a delay in project implementation. The way in which an EIA is
carried out is not rigid: it is a process comprising a series of steps. These steps are outlined below
and the techniques more commonly used in EIA are described in some detail in the section
Techniques. The main steps in the EIA process are:
1) Screening
2) Scoping
3) Prediction and mitigation
4) Management and monitoring
5) Audit
Screening often results in a categorization of the project and from this a decision is
made on whether or not a full EIA is to be carried out.
Scoping is the process of determining which are the most critical issues to study and
will involve community participation to some degree. It is at this early stage that EIA
can most strongly influence the outline proposal.
Detailed prediction and mitigation studies follow scoping and are carried out in
parallel with feasibility studies.
The main output report is called an Environmental Impact Statement, and contains a
detailed plan for managing and monitoring environmental impacts both during and
after implementation.
Finally, an audit of the EIA process is carried out sometime after implementation. The
audit serves a useful feedback and learning function.
The following figure shows a general flow diagram of the EIA process, how it fits in with
parallel technical and economic studies and the role of public participation.

STEPS OF EIA IN DETAILS:
Screening
Screening is the process of deciding on whether an EIA is required. This may be determined by
size (e.g. greater than a predetermined surface area of irrigated land that would be affected, more
than a certain percentage or flow to be diverted or more than a certain capital expenditure).
Alternatively it may be based on site-specific information. For example, the repair of a recently
destroyed diversion structure is unlikely to require an EIA whilst a major new headwork
structure may. Guidelines for whether or not an EIA is required will be country specific
depending on the laws or norms in operation. Legislation often specifies the criteria for screening
and full EIA. All major donors screen projects presented for financing to decide whether an EIA
is required.
The output from the screening process is often a document called an Initial Environmental
Examination or Evaluation (IEE). The main conclusion will be a classification of the project
according to its likely environmental sensitivity. This will determine whether an EIA is needed
and if so to what detail.
Scoping
Scoping occurs early in the project cycle at the same time as outline planning and pre-feasibility
studies. Scoping is the process of identifying the key environmental issues and is perhaps the
most important step in an EIA. Several groups, particularly decision makers, the local population
and the scientific community, have an interest in helping to deliberate the issues which should be
considered, and scoping is designed to canvass their views, (Wathern 1988).
Scoping is important for two reasons. First, so that problems can be pinpointed early allowing
mitigating design changes to be made before expensive detailed work is carried out. Secondly, to
ensure that detailed prediction work is only carried out for important issues. It is not the purpose
of an EIA to carry out exhaustive studies on all environmental impacts for all projects. If key
issues are identified and a full scale EIA considered necessary then the scoping should include
terms of reference for these further studies.
At this stage the option exists for cancelling or drastically revising the project should major
environmental problems be identified. Equally it may be the end of the EIA process should the
impacts be found to be insignificant. Once this stage has passed, the opportunity for major
changes to the project is restricted.
Before the scoping exercise can be fully started, the remit of the study needs to be defined and
agreed by the relevant parties. These will vary depending on the institutional structure. At a
minimum, those who should contribute to determining the remit will include those who decide
whether a policy or project is implemented, those carrying out the EIA (or responsible for having
8
it carried out by others) and those carrying out parallel engineering and economic studies relating
to the proposal. Chapter 5 gives details on preparing terms of reference for an EIA. A critical
issue to determine is the breadth of the study. For example, if a proposed project is to increase
the area of irrigated agriculture in a region by 10%, is the remit of the EIA to study the proposal
only or also to consider options that would have the same effect on production?
A major activity of scoping is to identify key interest groups, both governmental and non-
governmental, and to establish good lines of communication. People who are affected by the
project need to hear about it as soon as possible. Their knowledge and perspectives may have a
major bearing on the focus of the EIA. Rapid rural appraisal techniques provide a means of
assessing the needs and views of the affected population.
The main EIA techniques used in scoping are baseline studies, checklists, matrices and network
diagrams. These techniques collect and present knowledge and information in a straightforward
way so that logical decisions can be made about which impacts are most significant. Risk and
uncertainty are discussed further in the section managing uncertainty.
Prediction and mitigation
Once the scoping exercise is complete and the major impacts to be studied have been identified,
prediction work can start. This stage forms the central part of an EIA. Several major options are
likely to have been proposed either at the scoping stage or before and each option may require
separate prediction studies. Realistic and affordable mitigating measures cannot be proposed
without first estimating the scope of the impacts, which should be in monetary terms wherever
possible. It then becomes important to quantify the impact of the suggested improvements by
further prediction work. Clearly, options need to be discarded as soon as their unsuitability can
be proved or alternatives shown to be superior in environmental or economic terms, or both. It is
also important to test the "without project" scenario.
An important outcome of this stage will be recommendations for mitigating measures. This
would be contained in the Environmental Impact Statement. Clearly the aim will be to introduce
measures which minimize any identified adverse impacts and enhance positive impacts. Formal
and informal communication links need to be established with teams carrying out feasibility
studies so that their work can take proposals into account. Similarly, feasibility studies may
indicate that some options are technically or economically unacceptable and thus environmental
prediction work for these options will not be required.
Many mitigating measures do not define physical changes but require management or
institutional changes or additional investment, such as for health services. Mitigating measures
may also be procedural changes, for example, the introduction of, or increase in, irrigation
service fees to promote efficiency and water conservation. Table 6 in Chapter 4 describes the
most common adverse impacts associated with irrigation and drainage schemes and some
appropriate mitigating measures.
9
By the time prediction and mitigation are undertaken, the project preparation will be advanced
and a decision will most likely have been made to proceed with the project. Considerable
expenditure may have already been made and budgets allocated for the implementation of the
project. Major changes could be disruptive to project processing and only accepted if prediction
shows that impacts will be considerably worse than originally identified at the scoping stage. For
example, an acceptable measure might be to alter the mode of operation of a reservoir to protect
downstream fisheries, but a measure proposing an alternative to dam construction could be
highly contentious at this stage. To avoid conflict it is important that the EIA process commences
early in the project cycle.
This phase of an EIA will require good management of a wide range of technical specialists with
particular emphasis on:
prediction methods;
interpretation of predictions, with and without mitigating measures;
assessment of comparisons.
It is important to assess the required level of accuracy of predictions. Mathematical modelling is
a valuable technique, but care must be taken to choose models that suit the available data.
Because of the level of available knowledge and the complexity of the systems, physical systems
are modelled more successfully than ecological systems which in turn are more successfully
modelled than social systems. Social studies (including institutional capacity studies) will
probably produce output in non-numerical terms. Expert advice, particularly from experts
familiar with the locality, can provide quantification of impacts that cannot be modelled. Various
techniques are available to remove the bias of individual opinion.
Checklists, matrices, networks diagrams, graphical comparisons and overlays, are all techniques
developed to help carry out an EIA and present the results of an EIA in a format useful for
comparing options. The main quantifiable methods of comparing options are by applying
weightings, to environmental impacts or using economic cost-benefit analysis or a combination
of the two. Numerical values, or weightings, can be applied to different environmental impacts to
(subjectively) define their relative importance. Assigning economic values to all environmental
impacts is not recommended as the issues are obscured by the single, final answer. However,
economic techniques, can provide insight into comparative importance where different
environmental impacts are to be compared, such as either losing more wetlands or resettling a
greater number of people.
When comparing a range of proposals or a variety of mitigation or enhancement activities, a
number of characteristics of different impacts need to be highlighted. The relative importance of
impacts needs agreeing, usually following a method of reaching a consensus but including
economic considerations. The uncertainty in predicting the impact should be clearly noted.
10
Finally, the time frame in which the impact will occur should be indicated, including whether or
not the impact is irreversible.
Management and monitoring
The part of the EIS covering monitoring and management is often referred to as the
Environmental Action Plan or Environmental Management Plan. This section not only sets out
the mitigation measures needed for environmental management, both in the short and long term,
but also the institutional requirements for implementation. The term 'institutional' is used here in
its broadest context to encompass relationships:
established by law between individuals and government;
between individuals and groups involved in economic transactions;
developed to articulate legal, financial and administrative links among public agencies;
motivated by socio-psychological stimuli among groups and individuals (Craine, 1971).
The above list highlights the breadth of options available for environmental management,
namely: changes in law; changes in prices; changes in governmental institutions; and, changes in
culture which may be influenced by education and information dissemination. All the
management proposals need to be clearly defined and costed. One of the more straightforward
and effective changes is to set-up a monitoring programme with clear definition as to which
agencies are responsible for data collection, collation, interpretation and implementation of
management measures.
The purpose of monitoring is to compare predicted and actual impacts, particularly if the impacts
are either very important or the scale of the impact cannot be very accurately predicted. The
results of monitoring can be used to manage the environment, particularly to highlight problems
early so that action can be taken. The range of parameters requiring monitoring may be broad or
narrow and will be dictated by the 'prediction and mitigation' stage of the EIA. Typical areas of
concern where monitoring is weak are: water quality, both inflow and outflow; stress in sensitive
ecosystems; soil fertility, particularly salinization problems; water related health hazards; equity
of water distributions; groundwater levels.
The use of satellite imagery to monitor changes in land use and the 'health' of the land and sea is
becoming more common and can prove a cost-effective tool, particularly in areas with poor
access. Remotely sensed data have the advantage of not being constrained by political and
administrative boundaries. They can be used as one particular overlay in a GIS. However,
authorization is needed for their use, which may be linked to national security issues, and may
thus be hampered by reluctant governments.
Monitoring should not be seen as an open-ended commitment to collect data. If the need for
monitoring ceases, data collection should cease. Conversely, monitoring may reveal the need for
more intensive study and the institutional infrastructure must be sufficiently flexible to adapt to
11
changing demands. The information obtained from monitoring and management can be
extremely useful for future EIAs, making them both more accurate and more efficient.
The Environmental Management Plan needs to not only include clear recommendations for
action and the procedures for their implementation but must also define a programme and costs.
It must be quite clear exactly how management and mitigation methods are phased with project
implementation and when costs will be incurred. Mitigation and management measures will not
be adopted unless they can be shown to be practicable and good value for money. The plan
should also stipulate that if, during project implementation, major changes are introduced, or if
the project is aborted, the EIA procedures will be re-started to evaluate the effect of such actions.
Auditing
In order to capitalise on the experience and knowledge gained, the last stage of an EIA is to carry
out an Environmental Audit some time after completion of the project or implementation of a
programme. It will therefore usually be done by a separate team of specialists to that working on
the bulk of the EIA. The audit should include an analysis of the technical, procedural and
decision-making aspects of the EIA. Technical aspects include: the adequacy of the baseline
studies, the accuracy of predictions and the suitability of mitigation measures. Procedural aspects
include: the efficiency of the procedure, the fairness of the public involvement measures and the
degree of coordination of roles and responsibilities. Decision-making aspects include: the utility
of the process for decision making and the implications for development, (adapted from Sadler in
Wathern, 1988). The audit will determine whether recommendations and requirements made by
the earlier EIA steps were incorporated successfully into project implementation. Lessons learnt
and formally described in an audit can greatly assist in future EIAs and build up the expertise
and efficiency of the concerned institutions.
Public participation
Projects or programmes have significant impacts on the local population. Whilst the aim is to
improve the well being of the population, a lack of understanding of the people and their society
may result in development that has considerable negative consequences. More significantly,
there may be divergence between national economic interests and those of the local population.
For example, the need to increase local rice production to satisfy increasing consumption in the
urban area may differ from the needs as perceived by the local farmers. To allow for this, public
participation in the planning process is essential. The EIA provides an ideal forum for checking
that the affected publics have been adequately consulted and their views taken into account in
project preparation.
The level of consultation will vary depending on the type of plan or project. New projects
involving resettlement or displacement will require the most extensive public participation. As
stated before, the purpose of an EIA is to improve projects and this, to some extent, can only be
achieved by involving those people directly or indirectly affected. The value of environmental
12
amenities is not absolute and consensus is one way of establishing values. Public consultation
will reveal new information, improve understanding and enable better choices to be made.
Without consultation, legitimate issues may not be heard, leading to conflict and
unsustainability.
The community should not only be consulted they should be actively involved in environmental
matters. The International Union for the Conservation of Nature, IUCN promotes the concept of
Primary Environmental Care whereby farmers, for example, with assistance from extension
services, are directly involved in environmental management. The earlier the public are involved,
the better. Ideally this will be before a development proposal is fully defined. It is an essential
feature of successful scoping, at which stage feedback will have the maximum influence.
Openness about uncertainty should be a significant feature of this process. As the EIA
progresses, public consultation is likely to be decreased though it is important to disseminate
information. The publication of the draft Environmental Impact Statement (EIS), will normally
be accompanied by some sort of public hearing that needs to be chaired by a person with good
communication skills. He/she may not be a member of the EIA team.
There are no clear rules about how to involve the public and it is important that the process
remains innovative and flexible. In practice, the views of people affected by the plan are likely to
be heard through some form of representation rather than directly. It is therefore important to
understand how decisions are made locally and what are the methods of communication,
including available government extension services. The range of groups outside the formal
structure with relevant information is likely to include: technical and scientific societies; Water
User Groups; NGOs; experts on local culture; and religious groups. However, it is important to
find out which groups are under-represented and which ones are responsible for access to natural
resources, namely: grazing, water, fishing and forest products. The views of racial minorities,
women, religious minorities, political minorities and lower cast groups are commonly
overlooked, (World Bank, 1991).
There has been an enormous increase in the number of environmental NGOs and "Green"
pressure groups throughout the world. Such organizations often bring environmental issues to the
attention of the local press. However, this should not deter consultation with such organizations
as the approach to EIA should be open and positive with the aim of making improvements.
Relevant NGOs should be identified and their experience and technical capacity put to good use.
In some countries, open public meetings are the most common technique to enable public
participation. However, the sort of open debate engendered at such meetings is often both
culturally alien and unacceptable. Alternative techniques must be used. Surveys, workshops,
small group meetings and interviews with key groups and individuals are all techniques that may
be useful. Tools such as maps, models and posters can help to illustrate points and improve
communication. Where resettlement is proposed, extensive public participation must be allowed
13
which will, at a minimum, involve an experienced anthropologist or sociologist who speaks the
local language. He/she can expect to spend months, rather than weeks, in the field.
Information dissemination can be achieved using a number of mechanisms including the
broadcasting media, in particular newspapers and radio. Posters and leaflets are also useful and
need to be distributed widely to such locations as schools, clinics, post offices, community
centers, religious buildings, bus stops, shops etc. The EIA process must be seen to be fair.
The public participation/consultation and information dissemination activities need to be planned
and budgeted. The social scientist team member should define how and when activities take
place and also the strategy: extensive field work is expensive. It is important to note that public
participation activities are often reported as a separate section of the final EIA. Where experience
of managing community involvement is limited, training is highly recommended. Further
reading on public participation can be obtained from: Ahmed L and G K Sammy (1988) and on
Rapid Rural Appraisal from Chambers R (1981). Rapid Rural Appraisal techniques may be an
appropriate and cost effective method of assessment.
Managing uncertainty
An EIA involves prediction and thus uncertainty is an integral part. There are two types of
uncertainty associated with environmental impact assessments: that associated with the process
and, that associated with predictions. With the former the uncertainty is whether the most
important impacts have been identified or whether recommendations will be acted upon or
ignored. For the latter the uncertainty is in the accuracy of the findings. The main types of
uncertainty and the ways in which they can be minimized are discussed by de Jongh in Wathern
(1988). They can be summarized as follows:
• Uncertainty of prediction: this is important at the data collection stage and the final certainty
will only be resolved once implementation commences. Research can reduce the uncertainty;
• Uncertainty of values: this reflects the approach taken in the EIA process. Final certainty will
be determined at the time decisions are made. Improved communications and extensive
negotiations should reduce this uncertainty;
• Uncertainty of related decision: this affects the decision making element of the EIA process
and final certainty will be determined by post evaluation. Improved coordination will reduce
uncertainty.
The importance of very wide consultation cannot be overemphasized in minimizing the risk of
missing important impacts. The significance of impacts is subjective, but the value judgements
required are best arrived at by consensus: public participation and consultation with a wide sector
of the community will reduce uncertainty. One commonly recurring theme is the dilemma of
whether to place greater value on short-term benefits or long-term problems.
14
The accuracy of predictions is dependent on a variety of factors such as lack of data or lack of
knowledge. It is important not to focus on predictions that are relatively easy to calculate at the
expense of impacts that may be far more significant but difficult to analyse. Prediction
capabilities are generally good in the physical and chemical sciences, moderate in ecological
sciences and poor in social sciences. Surveys are the most wide-spread technique for estimating
people's responses and possible future actions.
The results of the EIA should indicate the level of uncertainty with the use of confidence limits
and probability analyses wherever possible. Sensitivity analysis similar to that used in economic
evaluation could be used if adequate quantifiable data are available. A range of outcomes can be
found by repeating predictions and adjusting key variables.
EIA cannot give a precise picture of the future, much as the Economic Internal Rate of Return
cannot give a precise indication of economic success. EIA enables uncertainty to be managed
and, as such, is an aid to better decision making. A useful management axiom is to preserve
flexibility in the face of uncertainty.

Objective of EIA:
The objective of EIA is (i) to identify, predict and evaluate the economic, environmental and
social impact of development activities (ii) to provide information on the environmental
consequences for decision making and (iii) to promote environmentally sound and sustainable
development through the identification of appropriate alternatives and mitigation measures.
CONCLUSION:
An Environmental Impact Assessment (EIA) is a document prepared to describe the effects for
proposed activities on the environment. "Environment," in this case, is defined as the natural and
physical environment and the relationship of people with that environment. This means that the
"environment" considered in an EIA includes land, water, air, structures, living organisms,
environmental values at the site, and the social, cultural, and economic aspects. An "impact" is a
change in consequence that results from an activity. Impacts can be positive or negative or both.
An EIA describes impacts, as well as ways to "mitigate" impacts. To "mitigate" means to lessen
or remove negative impacts.
Therefore, an Environmental Impact Statement, or EIA, is a document that describes the impacts
on the environment as a result of a proposed action. It also describes impacts of alternatives as
well as plans to mitigate the impacts.
