OP/SE/3.1- Preparation of IEE & EIA Report
Purpose and Scope :

To meet DoE requirements all RHD road and bridge projects require an Initial Environmental Examination (IEE). This would be prepared (alongside any feasibility study report) for review in preparing all PCPs in RHD. All Road Projects, and Bridge Projects, over 100 m length are identified as having significant potential for environmental impact and are categorised into Red by the Department of Environment (DoE, clause-67 and 68). Therefore, a full EIA is also required. This should lead to sufficient focus given to environmental issues for all RHD road and bridge projects.
Definitions :

Environmental Impact Assessment (EIA) - Environmental Impact Assessment is the systematic study, assessment and reporting of the impacts of a proposed programme, plan or project, including a management plan for dealing with negative impacts. EIA is prepared at the feasibility level and include quantification and valuation of the impacts.

Environmental Management Plan (EMP) - EMP is a plan for environmental activities during project implementation designed to ensure sound environmental management to mitigate adverse environmental impacts and maximise beneficial environmental effects.

Initial Environmental Examination (IEE) - The first stage in the Environmental Assessment of a project at pre-feasibility level, for identifying and assessing possible environmental impacts.

Description of the Environment - It include, collection, scrutiny, evaluation and presentation of environmental data on the relevant environmental characteristics of the study area. Including information on any changes anticipated before the project commences.

Physical Environment - Covers geology; topography; soils; climate; ambient air quality; surface and ground water hydrology; existing sources of air emissions; existing water pollution discharges and receiving water quality.

Biological Environment - Include flora; fauna; rare or endangered species; sensitive habitats; species of commercial importance etc.

Socio-cultural Environment - It include population; land use; community structure; employment; distribution of income; development activities; recreation; public health; cultural properties; tribal peoples; etc.

Red Category Projects - The Road Construction Projects are identified as having significant potential for environmental impact. The following types are significant;

Road construction/ Re-construction/ Extension of Regional, National and International Road.

Bridge construction/ Re-construction and Extension over 100-meter length require an IEE followed by EIA.

Amber-B Category Projects: The following types of project fall under this category.

Construction/Reconstruction/Extension of Feeder Roads and Local Streets.

Construction/Reconstruction and Extension of Bridges less than 100 meters length.

As per DoE an IEE is required for Amber-B Projects, but RHD realises that if significant environmental negative impacts occur, then an EIA should be prepared.
Responsibility :

Superintending Engineer - Social & Environment Circle (SE-SEC)

Ensure proper monitoring of the environmental assessment study of all RHD works.

After a careful review, he will change or modify the EA reports (IEE and EIA) or send it to field level staff or Project Authority for cross checking of data and information. He also sends the approved EA report to EE-Field Circle for obtaining environmental clearance.

Executive Engineer - Environment Division (EE-ED)

Responsible for reviewing environmental assessment RFP in relation to project description and design.

Responsible for reviewing environmental assessment report (IEE or EIA), comment on the list of Significant Environmental Impacts (SEI's) identified by the consultant and participate in the discussion between EE-Field & the consultant on the magnitude of each impact, distribute the report to relevant sections. He also gives decision whether further study by the consultant is to be carried out on certain environmental issues or impacts.

Responsible to review plan and methodology submitted by the consultant for further study of IEE or EIA. He also sends the report to the SE or sends back to the consultant for additional study.

Review and comment on the EIA Report prepared by the consultant and submit the report with comments to the Superintending Engineer, Social and Environment Circle for further action.

Executive Engineer - Field Division (EE-FD)

He is responsible to prepare RFP for Environmental Assessment in association with Environment Division, RHD.

He is responsible towards selection of Consultant for Environmental Study.

Responsible to issue work order to the selected Consultant.

Familiarise the project area to the environmental study team.

In consultation with the study team, involve in careful delineation of project area; study area and impact area.

Evaluation of a study team, comprising multi-disciplinary personnel.

Participate in the discussion on engineering, environmental and social issues, supply relevant maps and field level information, arrange discussion between the consultant and the EE-ED on significant issues and magnitude of each predicted impact, give decisions regarding supporting study needs.

Initiate contacts and formal meetings with relevant agencies (City Corporation, LGED; BWDB etc).

Responsible to distribute IEE or EIA reports to concerned sections of RHD.

Prepare application for obtaining Environmental Clearance from the Department of Environment.

Ensure safe working practices on site.

Superintending Engineer - Field (SE-F)

He is responsible for initiating Environmental Clearance from the Department of Environment (DoE), accordingly he is to forward an application along with an IEE or EIA document to the DoE, he also distribute the approved IEE or EIA report to concerned RHD officers.
Method :


The Request for Proposal (RFP) is the basis for Environmental Assessment, which is usually developed by the Executive Engineer-Field/Project Authority in consultation with Social and Environment Circle and following the procedures/guidelines of RHD. The RFP for an EA should state the purpose of the EA, provide background and guidance for the study team, set the schedule and deliverables of the EA report and serve as the contractual basis for commissioning the work. The Executive Engineer, field divisions (EE-FD) initiate at the preparatory stage of EA field study and supply all projects related documents to the consultant. The consultant obtains detailed maps, initial information of the project area. The Sub-Divisional Engineer under the Field Division assists the EE and the consultants in this process.


The Consultant should review the existing environmental policies, guidelines, regulations and DoE procedures for obtaining Environmental Clearance. The secondary source data should be collected for preparation of IEE report by the consultants. The IEE Report should contain a) Description of the project, b) Policy and legislative aspects, c) Description of the environment, d) Identify predicted impacts and e) an environmental management Plan. Finally, the consultant submits a draft IEE report to Executive Engineer-Environment Division. After refinement, the IEE is finalised and sent to DoE for environmental clearance.


The consultant, in association with the Executive Engineer-Field Division (EE-FD), should identify regulations and guidelines that will govern the conduct of the assessment or specify the contents of its report. They may include a) RHD Environmental Guidelines, b) National laws and regulations on environmental reviews and impact assessments, c) Donor requirements, d) RHD environmental goals and objectives. At this stage checklists, formats etc. to be finalised following RHD requirement.

In some cases, the tasks to be carried out by the consultant will be known with sufficient certainty to be specified completely in the RFP. In other cases, information deficiencies need to be alleviated or specialised field studies performed to assess impacts, and the consultant will be asked to define particular tasks in more detail for RHD Social & Environment Circle review and approval. The EIA should contain:

Project Description: Describe nature of the proposed project, location and type of roads, bridges, expected volume of use, construction activities etc.

Legislative and Regulatory Considerations: Describe the pertinent regulations and standards governing environmental quality.

Description of the present state of the environment (physical, biological, socio-cultural), collect primary and secondary data from field and relevant agencies.

Determination of potential impacts: The engineering plans should reflect 'best practice' in road alignment, design, construction methods etc. to ensure that potential negative environmental impacts are minimised.

Development of Environmental Management Plan (EMP) with focus on three generic areas: ie. Mitigation measures, institutional strengthening and training and monitoring.

After review of the EIA report, the Executive Engineer-Environment Division, determines whether further detailed study is required or not for the project. EIA is undertaken to clearly define the project with primary data support, the following sequences are carried out for additional refinement of the study.

Consultant, after discussions with the Executive Engineers-Field Division (EE-FD), carry out collection of additional field level primary data on the relevant environmental issues and follow the sequences such as, scoping, project definition, data collection, impact prediction and analysis etc.

The consultant in association with the Executive Engineers-Field Division (EE-FD), will finalise an EIA, which is a multidisciplinary, comprehensive, and detailed study at a feasibility level stage. In the EIA report predicted impacts are identified, quantified and valued, at the same time environmental management and mitigation measures are suggested. The Environment Division also reviews the EIA. Finally the SE-Field or Project Authority apply to the DoE for Environmental Clearance.

(Note: These operational procedures were prepared for use by RHD staff and are not necessarily complete treatments of the subject. For detailed advice please refer to the RHD Environmental Guidelines).
