- 2. Environmental Impact Assessment (EIA) Process By Mr.Allah Dad Khan A Lecture To students Visiting Professor the University of Agriculture Peshawar
- 3. Introduction Environmental impactassessment (EIA) is a systematic analysis of projects, policies, plans or programmes to determine their potential environmental impacts, the significance of such impacts and to propose measures to mitigate the negative ones. The underlying key principles of EIA are that every person is entitled to a clean and healthy environment and that every person has a duty to enhance, safeguard the environment. EIA is both a planning and decision- making tool. As a planning tool, EIA presents methodologies and techniques for identifying, predicting and evaluating potential environmental impacts of projects, policies, plans and programmes in the project cycle (planning, implementation and decommissioning phases). The EIA process presents decision- makers with the information necessary to determine whether or not a project should be implemented.
- 4. Principles of EIA The other main principles of EIA are: • Environmental concerns must be accounted for in all development activities • Public participation in the development of projects, policies, plans and programmes important • Recognition of social and cultural principles traditionally used in the management of the environment and natural resources • International cooperation in the use and wise management of shared resources • Intra- generational and inter-generational equity • Polluter-pays principle • The precautionary principle
- 5. Objectives of EIA The overall objective of EIA is to ensure that environmental concerns are integrated in all development activities in order to contribute to contribute to sustainable development. The specific objectives are: a) To identify potential environmental impacts of proposed projects, policies, plans and programmes b) To assess the significance of these impacts c) To assess the relative importance of the impacts of alternative plans, designs and sites; d) To propose mitigation measures for the significant negative impacts of the project on the environment; e) To generate baseline data for monitoring and evaluation of how well the mitigation measures are being implemented during the project cycle; f) To present information on the impact of alternatives; g) To present results of the EIA in such a way that they can guide informed decisionmaking.
- 6. Screening of activities Screening involves determining whether or not an EIA study is required for a particular development activity. This depends on the significance of the project’s environmental impacts. The significance itself depends on such factors as: the sensitivity of the area likely to be affected; public health and safety; the possibility of uncertain, unique or unknown risks; the possibility of having individually insignificant but cumulatively significant impacts; whether the proposed activity affects protected areas, endangered or threatened species and habitats; size, working methods, project activities including their duration and proposals for waste disposal etc. A hybrid of approaches involving lists and thresholds, amongst others, are used to establish which activities should be assessed for environmental impacts. This is the initial phase in the EIA process. The screening exercise usually involves the following
- 7. Screening of activities Project and site description • Collection of baseline data • Data analysis • Evaluation of significance of environmental impacts • Evaluation of alternatives • Consultation and public participation; • Preparation of a project report; • Review of project report and • Approval process
- 8. Site and ProjectDescription Comprehensive site description includes the following aspects: • Location of the project • Soils and geology • Water resources, • Drainage • Climate, • Vegetation, • Land use, • Population characteristics, • Infrastructure, and • Justification for selecting the site
- 9. Site and ProjectDescription Also comprehensive information is required on: • Nature of the proposed project • Project activities • Materials to be used in the project • Project outputs including waste
- 10. Collection of BaselineData Baseline data should be identified, collected and used to describe the status of the project site before any activity related to project implementation commences. The baseline data are used to assess potential impacts on health, safety, the environment and the community. Environmental data collection programmes must be kept within manageable proportions taking into consideration the length of time available for the study. It is also advisable to infer, extrapolate, or predict environmental conditions and responses from baseline information or from other similar cases where actual data is lacking.
- 11. Data Analysis andEvaluation of Alternatives In analyzing data, the following methods may be used: checklist, matrix, threshold limit, overlay, etc. In evaluating alternatives, emphasis should be on the following: project, location, technology, scale, etc.
- 12. Consultation and PublicParticipation It is important that all persons likely to be affected by the project are consulted for their concerns. Information regarding all project activities within the project cycle (planning implementation, decommissioning), materials to be used, products, waste and waste disposal, economic and social benefits should be provided. The views of the public on all these activities should be incorporated in the project report.
- 13. Preparation of theProject Report An Environmental Impact Assessment Expert should prepare the project report. In addition to these Guidelines, the EIA expert should familiarize himself/herself with the Environmental (Impact Assessment and Audit) Regulations 2002.
- 14. Contents of theProject Report A project report should include the following details: (a) Name of the proponent, PIN number, address and contact person (b) Title of the project (c) Objectives and scope of the project (d) Nature of the project; (e) Location of the proposed project, including the physical area that may be affected by the project’s activities; (f) Types of activities that will be undertaken during the project construction, operation and decommissioning phases; (g) Design(s) of the project; (h) Materials to be used, products and by-products, including waste to be generated by the project and the method(s) of their disposal; (i) Potential environmental impacts of the project; (j) Mitigation measures to be taken during and after implementation of the project; (k) An action plan for the prevention and management of foreseeable accidents during the project cycle; (l) A plan to ensure the health and safety of the workers, and neighboring communities; (m) Economic and social benefits to the local community and the nation in general; (n) Project budget; (o) Views of the public about the project, indicating representativeness of the potentially affected people; and (p) An environmental management plan (EMP) for the entire project cycle.
- 15. Submission of theProject Report On completion, the proponent shall submit the project report to the Authority for review.
- 16. The Review Process The aim of the review exercise is to ensure the that following major aspects have been 8 adequately addressed in the report: • Impact identification • Impact assessment • Adequacy of proposed mitigation measures • Adequate consideration of project alternatives • Evidence and adequacy of consultation and public participation • Implementation process and procedures • Comprehensiveness of the environmental management plan
- 17. Decision-Making Where theAuthority is satisfied that the project will not have significant environmental impacts or that the proposed mitigation measures are adequate to address the identified impacts, the Authority may issue the EIA License with conditions of approval, if any. If the project will have significant environmental impacts and the project report does not disclose adequate mitigation measures, the Authority shall require the proponent to undertake an environmental impact assessment study, which will assist in determining whether an EIA License can be issued.
- 18. Scoping of impacts A project that the Authority considers should be subjected to an EIA study must first undergo a scoping study. Scoping is a procedure used to determine the range of issues to be addressed in the EIA study; it also is the process of identifying the significant issues, which are related to the proposed project. Its main objective is to focus the EIA on the key issues, while ensuring that indirect and secondary effects are not overlooked and eliminating irrelevant impacts. Thus, scoping identifies the key concerns, evaluates them, organizes and presents them to aid decision-making. Like in screening, scoping hinges on the issue of significance. It is during scoping that the Terms of Reference (TOR) for an EIA Study are formulated. Impacts are predicted from the scoping exercise using one or several techniques e.g. ad-hoc methods, checklists, matrices, networks, overlays, cost-benefit analysis, etc.
- 19. Objectives of Scoping The specific objectives of scoping are to: • Identify key issues of concern • Ensure focus on key issues during the EIA study • Facilitate focused specialist studies • Determine the assessment methods to be used. • Identify all affected persons. • Provide an opportunity for consultation and public participation. • Facilitate identification of alternatives. • Facilitate early agreement on contentious issues. • Save time and money.
- 20. Steps to beconsidered in scoping Scoping must ensure continuous consultation between the proponent, the experts, the public (especially potentially affected persons) and the Authority. Consequently, the following steps are involved: • Develop a communication plan (decide who to talk to and when) • • • • • • Assemble information that will be the starting point of discussion Make the information available to those whose views are to obtained Find out what issues people are concerned about. Make a long list Look at the issues from a technical perspective in preparation for further study Organize the information according to issues (grouping, combining and setting priorities) Develop a strategy for addressing and resolving each key issue, including information requirements and terms of reference for further studies
- 21. Assembling Relevant ExistingInformation Information should be collected on the nature of the project, including the list of potential environmental impacts and practical alternatives accompanied by maps, drawings and other aids for further understanding of the proposed project. The information will help in formulating appropriate mitigation measures and will form the basis for further discussion. Affected persons should be consulted, involved and made to understand all the issues of concern relating to the project, which should be compiled into a comprehensive list.
- 22. Identifying and PrioritizingIssues of Environmental Concern Once the issues have been identified and grouped, their scientific validity needs to be carefully evaluated and their significance analyzed. If certain issues of technical nature remain unresolved, a specialist discussion panel or workshop can be organized at an appropriate venue to resolve the issues.
- 23. Consultation and PublicParticipation (CPP) Consultation and public participation is an important tool for those conducting a scoping exercise. It should be planned to focus on the affected persons. Methods for involving affected persons and for collecting information include: a) Securing written submissions from Lead Agencies and the public b) Public opinion c) Holding community meetings and public hearings d) Conducting preliminary field study/site visits e) Conducting workshops/seminars. f) Establishing inter-sector task forces
- 24. Contents of theScoping Report The Terms of Reference for an EIAS shall be contained in a scoping report that will be submitted to the Authority for approval. TOR prepared during a scoping exercise should provide specific guidelines for undertaking the EIA study. The scoping results will include, but will not limited to, the following aspects:

- 27. Project ObjectivesThis section will indicate the goals and specific objectives of the project
- 28. Existing EnvironmentalConditions Description of the project area, ecological zoning as well as the state of environment in the project area and its surrounding should be given. It should also be established whether the current environmental condition is in its natural state or it has already suffered degradation. If the latter is true, the causes of the original degradation should be established and if possible, the state of the environment before the observed degradation
- 29. Existing Environmental Conditions Description of the project area, ecological zoning as well as the state of environment in the project area and its surrounding should be given. It should also be established whether the current environmental condition is in its natural state or it has already suffered degradation. If the latter is true, the causes of the original degradation should be established and if possible, the state of the environment before the observed degradation
- 30. Proposed Project Activities The scoping Report shall disclose all proposed project activities identified in the project cycle
- 31. Identification of EnvironmentalImpacts A distinction should be made between significant positive and negative impacts, direct and indirect impacts, and immediate and long–term impacts. Also, identify impacts which are unavoidable and/or irreversible.
- 32. Social Analysis ofthe Project Alternatives Identify potential alternatives to the proposed project. Compare alternatives with respect to site, technology, product mix, scale, potential environmental impacts, capital and operating costs, suitability under local conditions, and institutional, training, and monitoring requirements. Indicate which impacts are irreversible or unavoidable and those that can be mitigated. The alternatives should include a “no project” alternative, in order to demonstrate environmental conditions without it.
- 33. Consultation and PublicParticipation It should also be spelt out how the affected community will be involved in the project formulation either through public meetings “barazas”, questionnaires and direct interviews 11 depending on the interest groups identified at the initial environmental impact assessment.
- 34. Social Analysis Evaluatethe economics of the project and establish its viability in terms of the expected environmental concerns and measures. Environmental costs should be treated as part and parcel of the necessary investment costs The communities' capacity to pay or shoulder the necessary cost or impact of environmental conservation measures should also be established.
- 35. Possible Analysis InformationGaps Indication should be given on how the information gathered will be evaluated to give optimum results. Required or necessary comparisons should also be spelt out and where possible areas of further investigation for continued monitoring should be identified.
- 36. Proposed Mitigation MeasuresRecommend feasible and cost–effective measures to prevent or reduce significant negative impacts to acceptable levels
- 37. Environmental Impact AssessmentStudy (EIAS) An EIA Study shall address all the issues contained in the TOR developed by the proponent in consultation with the lead agency and the Authority. The EIA study shall be undertaken by EIA experts registered by the Authority. The EIA study shall be the responsibility of the proponent.
- 38. The steps ofthe EIA study will include:- 1. Assemble the team of experts 2. Examine the TORs for each expert and • assign responsibilities to each member of the team • specify that the lead expert shall be responsible for the study • agree on time schedules 3. Plan field work including consultations and public participation and provision for: • collection of baseline data and information • awareness creation • generation of primary data • ecological, socio- cultural and economic surveys • designing of EMP to implement the mitigation measures and involving all the affected persons. 4. Report writing
- 39. Project Impact Identification This will involve naming all sources of impacts, e.g. smoke emissions, water consumption, construction jobs, using checklist or questionnaires. These will be matched with possible receptors of the impacts e.g. crops, communities using the same water.
- 40. Prediction The impactson the environment and the local communities will be analysed. The analysis shall examine biological, social, economic, and physical anthropological effects of the project. The analytical process will involve use of physical, socio–cultural, mathematical, and economic models including an evaluation of costs and benefits. The models will require expert judgment for accurate predictions.
- 41. Evaluation Presentation andInterpretation The evaluation will compare impacts of different options in order to facilitate selection of the best option. This will involve determining the importance of impacts relative to one another. The presentation should include cross– tabulation diagrams, graphics and maps. The degree of severity of these impacts will be assessed in economic terms through use of techniques such as the cost benefit analysis that must take into account both qualitative and quantitative aspects.
- 42. Mitigation Measures Thedetailed report will identify fully the proposed measures that shall be implemented to address the identified adverse effects. Similarly, the effectiveness of these measures towards achieving desired objectives shall be assessed. A wide range of options will be proposed to prevent, reduce, remedy, or compensate for the various adverse effects
- 43. Monitoring and EvaluationPlan Based on the baseline data of the EIA, a comprehensive monitoring and evaluation plan should be designed. This would be important in implementation and operation stages of project as a measure of compliance. 13 The EIAS reports are prepared on behalf of project proponents by Environmental Impact Assessment Experts legally registered by the Authority.
- 44. Format of anEIA Study Report A proponent shall submit to the Authority, an environmental impact assessment study report incorporating but not limited to the following information:- (a) a proposed location of the project; (b) a concise description of the national environmental legislative and regulatory framework, baseline information, and any other relevant information related to the project; (c) the objectives of the project; (d) the technology and processes to be used, in the implementation of the project; (e) the materials to be used in the construction and implementation of the project; (f) the products, by products and waste generated by the project; (g) a description of the potentially affected environment; (h) the environmental effects of the project including the social and cultural effects and the direct, indirect, cumulative irreversible, short-term and long- term effects anticipated; (i) alternative technologies and processes available and reasons for preferring the chosen technology and processes; (j) analysis of alternatives including project site, design and technologies and reasons for preferring the proposed site, design and technologies. (k) an environmental management plan proposing the measures for eliminating, minimizing or mitigating adverse impacts on the environment; including the cost, time frame and responsibility to implement the measures; (l) provision of an action plan for the prevention and management of foreseeable accidents and hazardous activities in the cause of carrying out activities or major industrial and other development projects; (m) the measures to prevent health hazards and to ensure security in the working environment for the employees and for the management of emergencies; (n) an identification of gaps in knowledge and uncertainties which were encountered in compiling the information; (o) An economic analysis of the project; (p) An indication of whether the environment of any other state is likely to be affected and the available alternatives and mitigating measures; and such other matters as the Authority may require.
- 45. Screening Screening isthe process of deciding on whether an EIA is required. This may be determined by size (eg 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.
