Environmental Impact Assessment is one of the important tools in environmental planning. This tool helps by guiding the decisions that affect nature, people, and its resources. The aim is to ensure a proper environmental clearance for development. EIA full formed as Environmental Impact Assessment, has become an important part of sustainable growth. 

It balances the need for development with the need to protect natural resources. Here, we cover several aspects related to Environmental Impact Assessment. Additionally, we are also going to cover the  EIA  history, impact, and other important details. So, keep referring as we provide all the crucial details. 

What is Environmental Impact Assessment?

Environmental Impact Assessment is a structured process. It checks how a project may harm air, water, land, or life. It also finds ways to reduce harm. The goal is a sound choice for society and nature. It ensures environment clearance from the right authority. It helps project owners avoid harm and plan well.

It also suggests ways to reduce or avoid those risks. For example, if a highway project may cut through a forest, the EIA will study possible damage to biodiversity and suggest alternatives or compensatory steps.

The key goal of Environmental Impact Assessment is to make sure that decision-makers consider the environment at the planning stage, and not after construction begins. This is why environment clearance is always given before the project starts. Without this clearance, the project is not legally valid.

History of Environmental Impact Assessment in India

The history of environmental impact assessment in India goes back more than four decades. In the late 1970s, large projects like dams and river valley projects were asked to provide environmental reviews. At that time, it was more of an administrative step rather than a legal requirement.

In 1986, the Environment (Protection) Act was passed. This Act gave the government the power to lay down rules for environmental protection. Using this authority, the first official notification on EIA was issued in 1994.

The 1994 notification listed certain industries and projects that could not start without prior clearance from the central government. This included thermal power plants, mining projects, chemical industries, and infrastructure projects. Over the years, many amendments were made to this notification, but it was still criticized for being too centralized and time-consuming.

To address these issues, the government issued a new environmental impact assessment notification in 2006. This became the base framework that continues even today, with several amendments made over time.

Environmental Impact Assessment Notification 2006

The EIA notification 2006 was a major reform in the field of environmental regulation. It aimed to decentralize decision-making, introduce more clarity, and involve local authorities.

Mentioned here are the key features of the Environmental Impact Assessment Notification 2006: 

• Categorization of Projects:
  • Category A: projects handled at the national level by the Ministry of Environment, Forest and Climate Change (MoEFCC).
  • Category B: projects handled by the State Environment Impact Assessment Authorities (SEIAA). Category B is further divided into B1 (which requires full EIA studies) and B2 (which are smaller projects and may be exempt from detailed studies).
• Stages of Assessment: The notification laid down a clear four-stage process – screening, scoping, public consultation, and appraisal.
• Public Participation: It emphasized the role of public hearings, where affected people can present their concerns before clearance is given.
• Time Limits: It sets timelines for each stage to avoid long delays.

This environmental impact assessment notification of 2006 remains the backbone of the clearance system, although it has been amended several times to respond to new challenges.

Environmental Impact Assessment Process

The Environmental Impact Assessment process is a structured method that ensures development projects are examined for their environmental effects before they begin. It involves several key stages that move from project planning to final approval. 

Check the steps of the Environmental Impact Assessment Process mentioned below: 

1. Screening
   • The project is reviewed to decide if it needs an EIA study.
   • Small projects may be exempt, while large projects automatically require assessment.
2. Scoping
   • Important issues, such as air quality, water use, waste generation, and biodiversity loss, are identified.
   • Terms of Reference (ToR) are prepared, which guide what the EIA report must include.
3. Baseline Data Collection
   • Information about the current state of the environment is collected.
   • Data on air, water, soil, noise, and living species in the project area is recorded for comparison.
4. Impact Prediction and Assessment
   • Likely environmental effects of the project are studied.
   • Both short-term and long-term impacts are assessed.
   • Direct and indirect effects on people, ecosystems, and resources are considered.
5. Mitigation Measures
   • Steps to reduce or avoid negative impacts are suggested.
   • This may include using cleaner technology, relocating facilities, or compensatory plantation.
6. EIA Report Preparation
   • A detailed report is created, summarizing findings, impacts, and mitigation plans.
   • This report forms the basis of further review.
7. Public Consultation
   • Local communities and stakeholders share their views.
   • A public hearing is conducted to record objections and suggestions.
8. Appraisal by Authorities
   • Expert committees review the EIA report and public feedback.
   • They check if the project has properly addressed environmental concerns.
9. Decision and Environment Clearance
   • Based on the appraisal, the competent authority either grants or rejects environment clearance.
   • If granted, clearance often includes specific conditions that the project must follow.
10. Monitoring and Compliance
    • Once the project begins, authorities monitor compliance with clearance conditions.
    • Periodic reports are submitted to ensure environmental safeguards are maintained.

Importance of Environmental Impact Assessment

The importance of Environmental Impact Assessment goes beyond just paperwork. It creates a balance between development and environmental protection.

• Sustainable Development: Projects are approved only when they maintain harmony between economic growth and environmental care. This ensures that future generations also benefit from natural resources.
• Protection of Natural Resources: Forests, rivers, soil, and wildlife are safeguarded through well-planned preventive steps. It reduces the risk of permanent damage to ecosystems.
• Transparency and Public Voice: Local communities get an opportunity to express their concerns before clearance is granted. This builds trust and makes decisions more accountable.
• Legal Security: Developers who follow the EIA process receive valid environment clearance. This lowers the chance of legal disputes, penalties, or project delays.
