EIA, Environmental Clearance & Coastal Regulation — EIA 2006, CRZ 2019, NGT, Forest Clearance & Green Tribunal

Overview

Environmental Impact Assessment (EIA) is the cornerstone of India's environmental governance — the process by which the potential environmental consequences of a proposed project are evaluated before it receives clearance. The Coastal Regulation Zone (CRZ) framework provides a parallel regulatory mechanism for India's 7,516.6 km coastline. Together, EIA and CRZ constitute the primary "green clearance" architecture through which development is reconciled with environmental protection.

Legal Framework for Environmental Clearances

India's environmental governance rests on a multi-layered legal architecture anchored in the Environment Protection Act, 1986 (EPA). The EPA was enacted in the aftermath of the 1984 Bhopal Gas Tragedy (and was also inspired by recommendations from the 1972 Stockholm Conference on Human Environment). Under Section 3, the Central Government is empowered to take all measures necessary to protect and improve environmental quality. The EIA Notification 2006 is the primary subsidiary legislation under EPA 1986 for project-level clearance, replacing the earlier EIA Notification of 1994.

Environmental Impact Assessment (EIA)

What Is EIA?

Project Categories Under EIA 2006

Projects are classified based on spatial extent of impact, magnitude of investment, and environmental sensitivity:

For Prelims: Category A = MoEFCC + EAC; Category B = SEIAA + SEAC. Screening determines whether Category B is B1 (full EIA) or B2 (exempted).

Four Stages of the EIA Process

Stage 1: Screening

Stage 2: Scoping

Stage 2B: EIA Study and Preparation of EIA/EMP Report

Stage 3: Public Consultation

EIS vs EIA: The Environmental Impact Statement (EIS) is the report prepared by the project proponent documenting potential impacts — it must be submitted before the public hearing so communities can review it. The EIA is the entire assessment process. UPSC exams use both terms — know the distinction.

Stage 4: Appraisal

Post-Clearance Obligations

• Half-yearly compliance reports submitted by proponents on the MoEFCC's Parivesh portal
• Compliance monitoring by the SPCB
• Environmental Management Plan (EMP) to be implemented

For Mains: The EIA process is designed to be participatory (public consultation), science-based (EIA report), and expert-reviewed (EAC/SEAC appraisal). However, critics argue that EIA reports are prepared by consultants hired by the project proponent (conflict of interest), public hearings are often poorly conducted, and compliance monitoring is weak.

Draft EIA Notification, 2020 — Controversies

The Draft EIA 2020 received over 1.7 million public comments — the highest for any draft notification in India's history. As of March 2026, the final notification has not been issued; the EIA Notification 2006 (as amended) remains in force.

Strategic Environmental Assessment (SEA)

Environmental Clearance for Specific Sectors

Mining

Infrastructure (Highways, Railways, Airports)

Forest Clearances — Forest Conservation Act

Original FCA 1980

The Forest Conservation Act, 1980 (FCA) requires Central Government approval for diversion of forest land for non-forest purposes (mining, roads, dams). No state government can dereserve forests or permit diversion without Central clearance.

Forest (Conservation) Amendment Act, 2023

The Forest (Conservation) Amendment Act, 2023 — also renamed Van Sanrakshan Evam Samvardhan Adhiniyam (Forest Conservation and Enhancement Act) — was passed by Lok Sabha on 26 July 2023 and Rajya Sabha on 2 August 2023, and received Presidential assent in August 2023:

Criticism: The 100 km exemption covers roughly 2/3 of northeast India, which contains some of the country's most biodiverse forests. Environmentalists warned this accelerates forest loss in already fragile ecosystems.

Two-Stage Forest Clearance Process

Stage I (In-Principle Approval): State government processes the proposal, obtains Gram Sabha consent (tribal areas), compensatory afforestation plan, and Net Present Value (NPV) payment commitment. Forest Advisory Committee (FAC) examines and forwards recommendation. Stage I approval is "in-principle" — no forest land can be broken.

Stage II (Final Clearance): After all Stage I conditions are met (compensatory afforestation + NPV payment), MoEFCC grants Stage II clearance, after which forest land diversion can begin.

Net Present Value (NPV): The economic value of ecosystem services foregone due to diversion of forest land — calculated per hectare based on forest quality and type. NPV rates were revised upward by the Supreme Court in 2008 to better reflect true ecological value.

Compensatory Afforestation (CAMPA)

For Prelims: CAMPA: Compensatory Afforestation Fund Act 2016 (effective 2018); ~₹95,000 crore corpus; 90:10 (State:Centre) distribution; mandatory when forest land is diverted.

Coastal Regulation Zone (CRZ) Notification, 2019

Evolution of CRZ Framework

CRZ Categories Under CRZ 2019

Key Features of CRZ 2019

For Mains: The CRZ 2019 relaxed several restrictions — particularly the NDZ reduction in densely populated rural areas. Critics argue this opens fragile coastlines to construction and tourism-driven degradation. Defenders argue the 200m NDZ was impractical in already populated areas and denied livelihoods to coastal communities.

Wildlife Clearances — NBWL

Projects within or adjacent to National Parks, Wildlife Sanctuaries, Conservation Reserves, and Community Reserves require additional clearance from the National Board for Wildlife (NBWL) under the Wildlife Protection Act, 1972.

The NBWL, chaired by the Prime Minister, has a Standing Committee (chaired by the Minister of Environment) for project clearances. The Supreme Court's Central Empowered Committee (CEC) monitors compliance in forest and wildlife matters under Godavarman and related orders.

Role of Expert Appraisal Committee (EAC)

National Green Tribunal (NGT)

Structure — Benches

Key Powers

• Suo motu cognisance of environmental issues (post-2012 judicial interpretation)
• Time-bound disposal — efforts to decide cases within 6 months
• Power to award compensation and restore damaged areas
• Orders are binding; appeals lie to the Supreme Court within 90 days

What NGT Cannot Do

• Criminal jurisdiction (must go to regular courts)
• Matters not covered under Schedule I laws
• Matters where the High Court has already taken up the issue under writ jurisdiction

NGT and Environmental Clearances

NGT has emerged as a key forum for challenging environmental clearances, EIA violations, and CRZ breaches — passing landmark orders on river pollution, waste management, and illegal construction in coastal areas.

• Aggrieved parties may challenge an Environmental Clearance before the NGT within 30 days of the grant of EC
• Over 38,000 cases have been filed before the NGT since its inception
• NGT has suo motu jurisdiction to take up environmental matters; its decisions are appealable only to the Supreme Court of India

Environmental Governance Structure

MoEFCC

The Ministry of Environment, Forest and Climate Change (MoEFCC) is the nodal agency:

Pollution Control Bodies

Parivesh Portal

The Parivesh (Pro-Active and Responsive facilitation by Interactive, Virtuous and Environmental Single-window Hub) portal was launched in 2018 as a single-window system for environment, forest, wildlife, and CRZ clearances — reducing delays, improving transparency, and enabling real-time tracking of pending applications.

Gaps in India's EIA Framework

Cumulative Impact Assessment (CIA)

India's EIA is project-specific — it does not require Cumulative Impact Assessment studying the combined effect of multiple projects in a basin or region. The Ganga basin hosts hundreds of hydropower projects whose cumulative impact on flows, sediment transport, and ecology has never been formally assessed as a whole. Expert committees have repeatedly called for mandatory CIA for sensitive river valleys and ecologically sensitive zones.

Post-Project Monitoring

Post-clearance compliance monitoring remains weak:

• Many projects do not submit compliance reports on time
• CPCB/SPCB inspections are infrequent
• Environmental Management Plans (EMPs) are often treated as formalities
• No mandatory third-party environmental audits (unlike global best practices)

Conflict of Interest in EIA Reports

EIA reports are prepared by consultants hired by the project proponent — creating a structural conflict of interest. Independent accreditation and randomised consultant assignment have been recommended but not yet implemented.

Key Violation Cases and Judicial Interventions

Green Ratings vs EIA

EIA is a regulatory requirement. Voluntary green building ratings operate separately:

Green ratings focus on energy efficiency, water conservation, and material use — they are not substitutes for EIA which covers broader ecosystem and pollution impacts.

Vocabulary

Environmental Impact Assessment (EIA)

• Pronunciation: /ɪnˌvaɪrənˈmɛntəl ˈɪmpækt əˌsɛsmənt/
• Definition: A systematic, interdisciplinary process to identify, predict, evaluate, and mitigate the biophysical, social, and other relevant effects of a proposed development project before a decision on environmental clearance is made — serving as a preventive tool that integrates environmental considerations into the planning and decision-making process.
• Origin: The concept originated with the US National Environmental Policy Act (NEPA, 1969); India adopted EIA through the EIA Notification, 1994 (under EPA, 1986), replaced by the current EIA Notification, 2006.

No Development Zone (NDZ)

• Pronunciation: /noʊ dɪˈvɛləpmənt zoʊn/
• Definition: A designated buffer area along India's coastline, measured from the High Tide Line (HTL) landward, within which construction of buildings and other development activities are prohibited or severely restricted — designed to protect fragile coastal ecosystems from encroachment and to serve as a natural buffer against storm surges and sea-level rise.
• Origin: Introduced under CRZ Notification, 1991; width: 50m in densely populated rural areas (CRZ-III(A)) and 200m in less populated rural areas (CRZ-III(B)) under CRZ 2019.

Key Terms

Expert Appraisal Committee (EAC)

• Pronunciation: /ˈɛkspɜːrt əˈpreɪzəl kəˈmɪti/
• Definition: A multi-disciplinary committee constituted by MoEFCC under the EIA Notification 2006, comprising experts in environmental science, ecology, engineering, health, and social sciences, tasked with scoping (determining Terms of Reference), appraising EIA reports, and recommending grant or rejection of environmental clearance for Category A projects — the equivalent state body is the State Expert Appraisal Committee (SEAC) for Category B.
• UPSC Relevance: GS3 (Environment). Prelims: EAC for Category A (MoEFCC), SEAC for Category B (SEIAA). Mains: effectiveness of EAC system; structural reforms needed (conflict of interest, randomised consultant assignment, mandatory site visits).
