Environment Impact Assessment Studies (EIA)

The EIA Process

EIA involves the steps mentioned below. However, the EIA process is cyclical with interaction between the various steps.

• Screening: The project plan is screened for scale of investment, location and type of development and if the project needs statutory clearance.
• Scoping: The project’s potential impacts, zone of impacts, mitigation possibilities and need for monitoring.
• Collection of baseline data: Baseline data is the environmental status of study area.
• Impact prediction: Positive and negative, reversible and irreversible and temporary and permanent impacts need to be predicted which presupposes a good understanding of the project by the assessment agency.
• Mitigation measures and EIA report: The EIA report should include the actions and steps for preventing, minimizing or by passing the impacts or else the level of compensation for probable environmental damage or loss.
• Public hearing: On completion of the EIA report, public and environmental groups living close to project site may be informed and consulted.
• Decision making: Impact Assessment Authority along with the experts consult the project-in-charge along with consultant to take the final decision, keeping in mind EIA and EMP (Environment Management Plan).
• Monitoring and implementation of environmental management plan: The various phases of implementation of the project are monitored.
• Assessment of Alternatives, Delineation of Mitigation Measures and Environmental Impact Assessment Report: For every project, possible alternatives should be identified, and environmental attributes compared. Alternatives should cover both project location and process technologies.
