The EIA Cycle and Procedures in India
The Environmental Impact Assessment (EIA) process in India consists of several steps. Each step ensures that environmental concerns are properly addressed while planning and implementing development projects.
Steps in the EIA Process
- Screening
- This step decides whether a project needs an EIA clearance.
- Screening depends on:
- The size of investment.
- The type of development.
- The location of the project.
- Only those projects listed in the EIA Notification or other rules require statutory clearance.
- Scoping
- Scoping defines what issues and impacts the EIA should study.
- The consultant prepares Terms of Reference (ToR) in consultation with the project proponent and the Impact Assessment Authority.
- The Ministry of Environment and Forests provides sector-specific guidelines.
- This step also identifies areas likely to be affected and the kind of baseline data to be collected.
- Baseline Data Collection
- Baseline data describes the current environmental status of the project site and nearby areas.
- Data includes site-specific measurements as well as available secondary information.
- Impact Prediction
- This step predicts how the project might change the environment.
- Impacts can never be predicted with complete certainty, but all possible effects are considered.
- Impacts are assessed for:
- Air: Emissions and their effects on health and vegetation.
- Noise: Increased noise levels and their effects.
- Water: Changes in quality and availability.
- Land: Changes in land use, drainage, and soil quality.
- Biological life: Effects on forests, wildlife habitats, rare species, and biodiversity.
- Society: Effects on human health, livelihoods, traffic, and local economy.
- Alternatives and Mitigation
- Various alternatives for project location and technology are compared.
- The best option with minimum environmental damage and maximum benefits is chosen.
- A Mitigation Plan and an Environmental Management Plan (EMP) are prepared.
- The EIA report clearly explains the likely scenarios:
- Without the project.
- With the project.
- With alternative designs.
- Public Hearing
- The public must be informed about the project and allowed to give feedback.
- Any local resident, association, or environmental group has the right to review the EIA summary and give suggestions to the State Pollution Control Board.
- Environmental Management Plan (EMP)
- The EMP explains:
- How mitigation measures will be implemented.
- Time schedules and responsibilities.
- Budget estimates for environmental protection.
- Unavoidable impacts and how they will be compensated.
- The EMP explains:
- Decision Making
- The Impact Assessment Authority and experts review the EIA and EMP.
- They decide whether the project should be approved, rejected, or modified.
- Monitoring
- The project is monitored during both construction and operation.
- Monitoring checks if:
- Commitments made in the EIA are followed.
- Actual impacts match predicted impacts.
- Corrective actions are taken if needed.
- Monitoring also helps improve the EIA process for future projects.
