Unit 4: EIA regulations

EIA Regulations in India

In India, EIA is legally mandated under the Environment (Protection) Act, 1986. The specific process is governed by the EIA Notification, issued by the Ministry of Environment, Forest and Climate Change (MoEFCC).

EIA Notification, 2006

This is the primary law that currently governs the EIA process in India (replacing the 1994 notification). It introduced several key changes:

1. Categorization of Projects:

The notification divides all projects into two categories:

• Category A (High Impact):
  • These are large-scale projects (e.g., major thermal power plants, large dams, airports).
  • They require a mandatory, comprehensive EIA.
  • They are appraised and cleared by the Central Government (MoEFCC).
• Category B (Lower Impact):
  • These are smaller projects (e.g., smaller dams, highways).
  • They are appraised and cleared by the State Government (State Environmental Impact Assessment Authority - SEIAA).
  • Category B is further split into:
    • Category B1: Requires a full EIA.
    • Category B2: Does *not* require an EIA (screened out by the state).

2. Four-Stage Process:

The 2006 Notification formalized the EIA process into four clear stages:

1. Screening: (Only for Category B projects) To see if the project is B1 (needs EIA) or B2 (doesn't need EIA).
2. Scoping: The process of determining the detailed Terms of Reference (TOR) for the EIA study.
3. Public Consultation: A mandatory step to get feedback from the public. It has two parts:
   • A public hearing at the project site.
   • Written comments from stakeholders.
4. Appraisal: The detailed review of the final EIA report (EIS) and public consultation findings by the government expert committee (Expert Appraisal Committee - EAC at the Center, or SEAC at the State). This leads to the final decision.

Status of EIA in India

EIA in India has evolved significantly and is now a standard part of all major project proposals. It has successfully stopped or modified many potentially damaging projects.

• Strengths:
  • Provides a legal framework for environmental protection.
  • Makes public consultation a mandatory part of the process.
  • Has increased environmental awareness among industries and developers.
• Weaknesses (see "Current Issues"):
  • The quality of EIA reports (EIS) is often poor.
  • The public consultation process is sometimes treated as a formality.
  • Monitoring and enforcement of the Environmental Management Plan (EMP) after approval is very weak.

Current Issues in EIA

Despite its successes, the EIA process in India faces several major challenges:

• Quality of EIA Reports: EIA reports are prepared by consultants paid by the project proponent. This creates a conflict of interest, often leading to reports that are biased, hide negative impacts, or use poor-quality "cut-and-paste" data.
• Public Hearing Issues: Public hearings are often poorly advertised, held in locations difficult for affected people to reach, or conducted in a hostile atmosphere. Technical EIA reports are not always available in local languages.
• Lack of Monitoring: This is the biggest failure. Once a project gets "Environmental Clearance" (EC), there is very little government monitoring to ensure the company is actually following the rules laid out in its Environmental Management Plan (EMP).
• Lack of Expertise: The government expert committees (EAC/SEAC) often lack the time, data, or specialized expertise to review complex projects thoroughly.
• Proposed Amendments: Recent draft amendments to the EIA notification (e.g., EIA 2020) have been highly controversial for trying to weaken the process, for example, by allowing "post-facto clearance" (legalizing projects that started *without* permission).

Case Study: Hydropower or Thermal Projects

These projects are classic examples for EIA because their impacts are so large and diverse.

Case Study: A Typical Hydropower Project (e.g., in the Himalayas)

A large dam built for electricity.

• Baseline Data: Would include river flow data, fish species (especially migratory fish), forest cover in the submergence area, and population of villages to be displaced.
• Predicted Negative Impacts:
  • Environmental: Submergence of forests and farmland (loss of biodiversity), fragmentation of the river (blocking fish), altered water flow downstream (affecting fisheries), risk of earthquakes.
  • Social: Displacement of thousands of people, loss of cultural sites, loss of livelihoods.
• Mitigation (EMP):
  • A detailed Resettlement and Rehabilitation (R&R) plan for displaced people.
  • Compensatory Afforestation (planting new trees, often in a different location).
  • Building a "fish ladder" to help fish migrate past the dam.
  • Maintaining a minimum "environmental flow" of water downstream.

Case Study: A Typical Thermal Power Project (Coal-based)

A power plant that burns coal to generate electricity.

• Baseline Data: Would include ambient air quality (PM₂.₅, SO₂, NOx), local water body quality, and local health statistics.
• Predicted Negative Impacts:
  • Air Pollution: Release of SO₂, NOx (causing acid rain) and large amounts of CO₂ (causing global warming).
  • Particulate Matter (PM): Fly ash from burning coal can cause severe respiratory problems.
  • Water Pollution: Hot water (thermal pollution) released from the plant's cooling system can kill aquatic life.
  • Solid Waste: Generation of huge quantities of fly ash, which needs to be stored in "ash ponds" that can leak and contaminate groundwater.
• Mitigation (EMP):
  • Installing Electrostatic Precipitators (ESPs) to capture fly ash.
  • Installing Flue Gas Desulfurization (FGD) or "scrubbers" to remove SO₂.
  • Building a cooling tower to cool hot water before it is released.
  • Properly lining ash ponds to prevent leaching.
