Introduction Environmental Impact Assessment (EIA) is a relatively new planning and decision making tool first enshrined in the United States in the National Environmental Policy Act of 1969. It is a formal study process used to predict the environmental consequences of any development project. It is a technique which is meant to help us understand the potential environmental impacts of major development proposals. It gives a view of the actors involved in the ‘developmentenvironment’ linkages. This is required in view of the fact that the community at large is always at a loss in terms of deterioration of living environment that accompanies industrial development. Based on Environmental Assessment, the regulatory measures can be identified and the roles of concerned agencies defined for achieving more efficient environmental management.

What is EIA? EIA is just an information gathering exercise carried out by the developer and other bodies which enables a Local Planning Authority to understand the environmental affects of a development before deciding whether or not it should go ahead. The really important thing about environmental assessments is the emphasis on using the best available sources of objective information and in carrying out a systematic and holistic process which should be bias free and allow the local authority and the whole community to properly understand the impact of the proposed development. Environmental impact assessment is meant to be a systematic process which leads to a final product, the Environmental Statement (ES). EIA is an iterative process. The key stages in the process include proposal identification, screening, scoping, impact assessment, mitigation, review, decision making and follow up. Good EIA is integrated into the project development process and is not seen as a barrier to development. Definition "Environmental Impact Assessment (EIA) is the process of assessing the likely environmental impacts of a proposal and identifying options to minimise environmental damage. The main purpose of EIA is to inform decision makers of the likely impacts of a proposal before a decision is made. EIA provides an opportunity to identify key issues and stakeholders early in the life of a proposal so that potentially adverse impacts can be addressed before final approval decisions are made." (Australian EIA Network). Immediate objectives of EIA are to:    

improve the environmental design of the proposal; check the environmental acceptability of the proposals compared to the capacity of the site and the receiving environment; 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.

Long term objectives of EIA are to:    

avoid irreversible changes and serious damage to the environment; safeguard valuable resources, natural areas and ecosystem components; enhance the social aspects of proposals; and protect human health and safety.

History of EIA EIA is one of the successful policy innovations of the 20th Century for environmental conservation. Thirty-seven years ago, there was no EIA but today, it is a formal process in many countries and is currently practiced in more than 100 countries. EIA as a mandatory regulatory procedure originated in the early 1970s, with the implementation of the National Environment Policy Act (NEPA) 1969 in the US. Much of the initial development was in a small number of high-income countries, like Canada, Australia, and New Zealand (1973-74). However, there were some developing countries as well, which introduced EIA relatively early - Columbia (1974), Philippines (1978). The EIA process really took off after the mid-1980s. In 1989, the World Bank adopted EIA for major development project, in which borrower country had to undertake the EIA under the Bank's supervision.

Stages/process in an EIA The EIA process is an iterative one containing many feedback loops to allow the development proposal to be continually refined. So whilst the process of EIA follows a number of commonly accepted steps, it does not observe a linear pattern. The EIA process is summarised in the figure below.

Proposal Identification A large number of decisions are made at the project identification and proposal development stage. Decisions are made regarding:   

the location of the development the land uses the development will cater for the scale, layout and design of the development.

If environmental issues are considered at this point in the development process, impacts can be significantly reduced and in some cases removed altogether. The advantages and disadvantages of the alternatives should be investigated, not only in environmental terms but also in terms of cost effectiveness, reasonableness and feasibility. The assessment of alternatives will result in the development of a preferred project proposal, which should then be the subject of a screening assessment. Screening Screening is undertaken to decide whether an EIA is required and focus resources on projects most likely to have significant impacts, those where impacts are uncertain and those where environmental management input is likely to be required. Official EIA guidelines usually contain lists or schedules specifying which developments require an EIA. These criteria include:   

development characteristics characteristics of the location characteristics of potential effects

Scoping During the scoping stage the key issues that the EIA will address are identified. Effective scoping will ensure that the EIA focuses on those areas where significant effects are likely, therefore preventing resources being used to address issues where no significant effects are likely. A good scoping process will consist of three key components: 

 

consultation with relevant stakeholders and interested parties to provide them with information on the development proposal and what technically appear to be the key issues and to find out what their key concerns are regarding the location and the development proposal; analysis of the issues identified during consultation to determine which are likely to be significant and therefore must be included within the scope of the EIA; and negotiation with the decision makers and other interested parties to refine the scope of the EIA.

There are a number of issues that are considered (to varying depths) within the scope of the majority of EIAs. These include:          

landscape and visual ecology land use traffic and transport air quality noise water ground conditions archaeology cultural heritage

Impact Analysis Impact analysis involves characterising the impact in terms of its likely nature, spatial and temporal distribution, duration, frequency, reversibility and magnitude. Finally a judgement must be made as to whether the impact is likely to be significant or not. A large number of impact analysis techniques exist, each have their advantages and disadvantages. Impact analysis techniques can be quantitative or qualitative. Quantitative techniques tend to involve a prescriptive method being set out and followed whereas qualitative techniques rely less upon a prescribed method instead relying heavily upon professional judgement. The nature of the environmental media being assessed will determine the most appropriate impact analysis technique. E-mail: [email protected]

Mitigation Where impact analysis identifies that a development is likely to give rise to significant environmental impacts, mitigation measures are proposed to avoid, reduce and if possible, remedy them. As mentioned briefly in the section on proposal identification above, mitigation measures can be incorporated into the design of the development. ‘End of pipe’ mitigation measures can also be incorporated into the development at a later stage. Environmental Statement The environmental statement is the vehicle used to communicate the results of the EIA to the decision maker and other stakeholders in the development process. The environmental statement should objectively document the EIA process and findings giving equal prominence to positive and negative impacts relative to their importance. The ES should be clear and concise. Because non specialists are likely to read the document technical language should be avoided. Any necessary technical information should be provided in appendices.

Review Quality control is an important stage in any EIA. A review of the quality of the environmental statement is a way of demonstrating that:   

the ES has met all the appropriate legal requirements the ES contains sufficient information to allow a decision to be made the ES is consistent with current good practice

A review of the ES can be undertaken at the draft stage or after finalisation. The earlier the review takes place the greater the influence it can have over the quality of the ES. Decision Making This is the point in the process where the development is either granted planning permission or not. It is necessary at this stage for the environmental statement to be made available to a number of statutory consultees, the public and other stakeholders. When making a decision on the application decision makers are required to consider all relevant environmental information, including the environmental statement and the opinions of statutory consultees, the public and other stakeholders. Environmental information is only one of many material considerations that the decision maker must take into account. The decision maker will also consider social and economic information, current planning policies and the relevant local development framework/local plan. The final decision will be based upon all of these things. Follow Up E-mail: [email protected]

Follow up is very important in EIA. It is the stage where the mitigation measures proposed within the environmental statement are actually implemented. It is also the stage where any necessary monitoring of impacts is undertaken. A common tool for ensuring that the measures proposed are implemented is a management plan. Management plans demonstrate a clear commitment to monitoring and mitigation measures and illustrate that the developer values the environment and the EIA process.

EIA in India The Ministry of Environment and Forests (MoEF) of India have been in a great effort in Environmental Impact Assessment in India. The main laws in nation are Water Act (1974), The Indian Wildlife (Protection) Act (1972), The Air (Prevention and Control of Pollution) Act (1981) and The Environment (Protection) Act (1986). The responsible body for this is Central Pollution Control Board. EIC is the repository of one stop secondary data source for environmental impact assessment in India. History of EIA in India The Indian experience with Environmental Impact Assessment began over 30 years back. It started in 1976-77 when the Planning Commission asked the Department of Science and Technology to examine the river-valley projects from environmental angle. This was subsequently extended to cover those projects, which required approval of the Public Investment Board. Till 1994, environmental clearance from the central government was an administrative decision and lacked the legislative support. On 27 January 1994, the Union ministry of environment and forests (MoEF), government of India, under the Environmental (Protection) Act 1986, promulgated EIA notification making Environmental Clearance (EC) mandatory for expansion or modernisation of any activity or for setting up new projects listed in Schedule 1 of the notification. Since then there have been 12 amendments made in EIA notification of 1994. The Indian Experience Experience on Environmental Impact Assessment (EIA) in India indicates that lack of availability of timely and reliable environmental data has been the major bottleneck in preparing quality EIA reports. Since environment is a multidisciplinary area, a multitude of agencies are involved in the collection of environmental data in India. However, there is no single organization in India that tracks the data available among the multitude of data generators and makes it available in the form and manner required by the practitioners in the field of EIA. This in turn affects the effectiveness of EIA process by causing delays in conducting EIAs and in reviewing the EIA reports for Environmental Clearance (EC). Further, the environmental data is often not available in a processed or value added form that can possibly enhance the quality of environmental decision making to address these issues, Environmental Information Centre (EIC) was conceived

to act as a clearinghouse of environmental data needed for preparation and review of EIAs. EIC data is also used as a project level decision support system for:     

Site selection Ecological degradation or improvements over time Early warning system for Glacier Lake Outbursts Catchment area degradation Determination of Environmental Status

Meta amino phenol Draw backs in the Indian system One of the biggest concerns with the environmental clearance process is related to the quality of EIA report that are being carried out. The reports are generally incomplete and provided with false data. EIA reports ignore several aspects while carrying out assessments and significant information is found to be omitted. Many EIA report are based on single season data and are not adequate to determine whether environmental clearance should be granted. All this makes the entire exercise contrary to its very intent. 

It is being found that the team formed for conducting EIA studies is lacking the expertise in various fields such as Anthropologists and Social Scientists (to study the social impact of the project) or even wild life experts. There is a lack of exhaustive ecological and socio-economic indicators for impact assessment. Public comments are not taken into account at the early stage, which often leads to conflict at the later stage of project clearance. There is always a lack of reliable data sources. The secondary data is also not reliable. The data collectors do not pay respect to the indigenous knowledge of local people. The credibility of the primary data collected by the data collectors is doubtful. The detail method used for the prediction and evaluation of the project is not mentioned in the report. Limited explanations are given both to quantitative estimation of magnitude of impact and to the assumptions and judgments used in the evaluation of impacts. The limited coverage of scoping is confined mainly to direct impacts. Details regarding the effectiveness and implementation of mitigation measures are often not provided. Often, and more so for strategic industries such as nuclear energy projected, the EMP s are kept confidential for political and administrative reasons Emergency preparedness plans are not discussed in sufficient details and the information not disseminated to the communities.

Conclusion The MoEF should provide specialised education and training to the staff of IAA and the PCBs. IAA and PCB staffs are the authorities responsible for the implementation of the EIA system. Therefore, a through understanding of public consultation and knowledge of the various components of the EIA studies such as the environment and social factors will provide benefits that will improve the quality of studies conducted. Training, especially in social sciences, will improve and further ensure that the proponents and consultants comply with the social aspects of EIA and adequately address public concerns. In addition, persons with social backgrounds should be hired by the Mom and PCBs to manage the social aspects of EIA. Information is important for creating awareness. One of the key conditions for managing the environment is information, such as knowledge about the environment and linkages between the environment and human environment (Gresham, et al., 1997). Participation is a function of information through which people come to share a development vision, make choices, and manage activities (World Bank, 1996b). People who participate are found to have better mass media contact and education (Muthayya, 1995)- It is important to note that lack of technical education is not a constraint on intelligence and the ability to understand one's surroundings (Environmental Protection Agency, 1996).
