6. Environmental Impact Assessment (EIA)

 • Environmental Assessment (EA), sometimes referred to as Environmental Impact Assessment (EIA) is a procedure for ensuring that the potential environmental effects of any new development or project are considered before it is allowed to proceed.

• Environmental assessment is a vital component in the concept of environmental management with environmental management system representing a useful tool for developers in conducting environmental assessments of their projects.

• Environmental Assessment (EA) is an appraisal technique for ensuring that the potential environmental effect of every new development are identified and considered before any approval is given.

• Environmental Assessment (EA) or Environmental Impact Assessment (EIA) as it is sometimes termed, is essentially the concept and process by which detailed information addressing the likely environmental effects of a development or project is gathered and evaluated by the developer or client organisation before being considered by the planning authority in deciding of planning permission should be formally granted. The collection of information documenting the projects potential-environmental effects is the environmental statement.

a. Environmental Statement (ES)

• The Environmental Statement (ES) is a publicly available document submitted to the planning authority and it accompanies the developer’s planning application.

• Generation of the environmental statement is the responsibility of the developer as it is gathering all the information and facts needed for its development. In practice, it is likely that the developer will employ a consultant to conduct the detailed investigation and produce the statement.

• The environmental statement may, depending upon circumstances, be brief and simple or lengthy and complex but it must provide a clear description of the projects likely environmental effects on a range of conventional environmental factors.

b. Benefits of EIA

• The benefits of the environmental impact assessment directive to organisations are that

1. It provides the basis for better decision making in the procurement of their projects.

2. It ensures that the potential environmental effects of their proposals are fully considered.

3. It allows the formulation of projects within a framework of greater safeguard and acceptability.

4. It promotes greater interaction between the developer and planning and approval authorities..

5. It provides the judgemental processes to be administered more systematically timely and effectively.

• Environmental assessment is a management function aimed at providing as much information as possible to allow the most appropriate and best decision to be reached in the interests of working within the environment.

• Environmental assessment in practice represents a two tier system of environmental consideration. Environmental assessment is therefore, in practical terms, a review and audit of the development process.

c. Participants to ES

• The following list represents the principal participants to the environmental assessment process.

1. The developer - Responsible for initiating and undertaking an environmental assessment of proposed development or projects.

2. Specialist consultants - Appointed by the developer to conduct the environmental assessment and produce the environmental statement to support the planning application. Specialist consultants may include; landscape architect, environmental scientist, design architect, engineer planner, other construction or life science related specialist.

a) The planning authority - The public body with responsibility for considering the environmental effects of a planning application.

b) The secretary of state - Involved in the environmental assessment decision making process in specific situations.

c) The public - May become involved in environmental assessment in publically sensitive projects where for example they may raise issues and objections with the planning authority or to the secretary of state.

d) Statutory and other consultees - Statutory and non statutory bodies may be asked to provide advice and information in the decision-making process. These involve such specialist organisations as the Countryside Commission, The Nature Conservancy Council, The Historic Building and Monuments Commission etc.

d. Role of Environmental Consultant

• The principal role of the environmental consultant within the environmental assessment process is to undertake the following.

1. Liaise with the developer on all aspects of environmental assessment.

2. Appraise the developer on matters of environmental legislation and regulations.

3. Liaise with other specialist consultants where required.

4. Liaise with the planning authority upon matters concerning the environmental assessment.

5. Liaise with statutory, non-statutory and other consultees who become involved in environmental assessment.

6. Undertake an Environmental Site Survey (ESS) to collect, collate and analyse the information necessary for the environmental assessment of the proposal.

7. Provide the environmental statement submitted with the developer’s planning application to the planning authority.

• The environmental consultant may be asked by the developer to,

a) Act in the capacity of environmental consultant during the briefing, design and procurement phases.

b) Act as environmental consultant during the construction phase on-site.

e. Stages of EIA

• There are seven principal elements in the process of environmental assessment. These are supported by one further element, essential to the realisation of success but which is frequently understood. These elements are,

1. Project description

2. Screening

3. Scoping

4. Baseline studies

5. Impact prediction / Identifying and evaluating alternatives

6. Mitigation assessment

7. Environmental statement

8. Environmental monitoring.

1. Project description

• This is a sufficient and clear description of the project together with details of its location.

• Although detailed information is not required at this initial stage, the developer must provide the planning authority with sufficient information to judge whether an environmental assessment is necessary.

2. Screening

• Screening is the process of determining for a particular project, the need for an environmental assessment.

3. Scoping

• Scoping is connected with directing the environmental assessment towards aspects of specific importance.

• Scoping is a vital step in the environmental assessment process as it must clearly identify those aspects which require detailed study and analysis and forms the basis for impact prediction of environmental effects.

• The result of scoping is the development of an environmental assessment programme or schedule which relates particular attributes of the development process to environmental aspect.

4. Baseline studies

• Baseline studies are concerned with the identification of the significant environmental impacts that must be assessed.

• Baseline studies follow on naturally from or even form an inherent part of scoping. The environmental assessment programme or schedule developed during scoping will direct the baseline study. This will provide information on -

a) The detailed description of the project.

b) The project's environs.

c) The social dimension.

5.  Impact prediction

• This is concerned with assessing the potential for environmental effect of those aspects identified during scoping and baseline studies.

• The focus of this aspects is, by definition, on determining the likely effect of specific project aspects upon the environment. Naturally it is difficult frequently impossible, to predict potential environmental effects with any degree of accuracy.

• Usually environmental impact prediction is a subjective description of what will happen, known from experience or what might happen based upon reasoning or expectation. Strictly, analysis should lead to accurate prediction based on verifiable information. It should be determined and not based on judgement or guesswork.

• In practice, environmental assessment should involve detailed investigation by experienced consultants and the resulting information presented in clear and unambiguous form, based on sound common sense reasoning of accurate data.

6. Mitigation assessment

• This focuses upon consideration of the measures to be taken to alleviate or minimise environmental effects.

• The accent of this section is towards summarising recommendations developed during the analytical and predictive processor, aimed at mitigating the environmental effects of the project.

7. Environmental statement

• The statement is the mechanism by which the developer places the findings of the environmental assessment before the planning authority. The extent and detail of an environmental statement will be determined by the characteristics and situation of the particular project.

8. Environmental monitoring

• Environmental monitoring is concerned with monitoring the environmental effects of the project, if and when the project is given approval to proceed.

• Environmental monitoring is essential as a concept, as it provides the sound base upon which wider principles and practices will undoubtedly advance in the future.

• It is rapidly becoming a prerequisite to the wider issues of environmental regulation and auditing schemes and looks set to play an even more significant role in the future.
