Quick answer
Environmental Impact Assessment under the EIA Notification, 2006 follows screening, scoping (Terms of Reference), baseline studies and an EIA report, public consultation where applicable and appraisal by an expert committee before Environmental Clearance is granted, followed by six-monthly compliance reporting.
1. The Role of the EIA
The Environmental Impact Assessment (EIA) is the most rigorous and profound environmental regulatory hurdle for mega-projects in India. Governed by the EIA Notification 2006 (under the EPA, 1986), it ensures that massive industrial expansions, mining projects, and thermal power plants systematically evaluate and mitigate their ecological footprint before a single brick is laid.
2. The Rigorous 4-Stage Process
Projects are divided into Category A (cleared by the Central MoEF&CC) and Category B (cleared by the State SEIAA). Both follow this mandatory pathway:
- Stage 1: Screening. The project proponent submits Form-1. The regulatory body determines if the project requires a full EIA, or if it is exempt due to small scale.
- Stage 2: Scoping. The Expert Appraisal Committee (EAC) dictates the 'Terms of Reference' (ToR). This is a massive checklist defining exactly what baseline environmental data (Air, Water, Soil, Flora/Fauna, Socio-economic) the consultant must physically collect over a 3-month season.
- Stage 3: Public Consultation. The draft EIA report is made public. The District Magistrate hosts a massive public hearing near the project site, allowing local villagers, NGOs, and stakeholders to voice their concerns. These concerns MUST be addressed in the final report.
- Stage 4: Appraisal. The EAC brutally scrutinizes the final EIA and the proposed Environmental Management Plan (EMP). If the ecological math checks out, Environmental Clearance (EC) is granted.
