Environmental Impact Assessment (EIA)
Human activities for food security and other needs have led to environmental concerns. EIA serves as a planning tool to integrate environmental concerns into developmental projects at an early stage. Its goal is to foresee and address potential environmental problems, ensuring sustainable development options. The Ministry of Environment & Forests (MoE&F) has introduced policies and regulations, including the EIA Notification of 1994, under the Environment (Protection) Act, 1986, to prevent resource exploitation and promote environmental integration in projects.
Indian Policies Requiring EIA
EIA in India began in 1976-77, initially focusing on river-valley projects. The Environment (Protection) Act, 1986 mandated EIA for projects and issued notifications covering specific geographical areas:
Tourism Prohibition: Restricted industrial locations in a 1 km belt along coastal and creek areas in Maharashtra (1989).
Doon Valley: Controlled mining and industrial activities (1989).
Coastal Regulation: Classified coastal stretches and prohibited certain activities (1991).
Dahanu Taluka: Restricted industrial activities in Maharashtra (1991).
Aravalli Range: Imposed restrictions in Haryana and Rajasthan (1992).
Numaligarh, Assam: Controlled pollution and congestion activities (1996).
Important Note: Khangchendzonga National Park (KNP), Sikkim, is India’s first “Mixed World Heritage Site,” listed by UNESCO for both natural and cultural heritage.
EIA Cycle and Procedures
The EIA cycle in India consists of the following phases:
Screening: Determines if a project requires environmental clearance based on investment, development type, and location.
Scoping: Details the terms of reference for the EIA, assessing quantifiable impacts (magnitude, frequency) and non-quantifiable impacts (aesthetic value).
Baseline Data Collection: Describes the existing environmental status of the study area using primary and supplementary data.
Impact Prediction: Maps potential environmental consequences, including impacts on air, noise, water, land, biological, and socio-economic aspects.
Assessment of Alternatives and Mitigation: Identifies project alternatives, ranks them, and prepares an Environmental Management Plan (EMP).
Public Hearing: Involves informing and consulting the public post-EIA report completion, inviting comments and suggestions.
Decision Making: Based on EIA and EMP evaluation, involves the impact assessment authority.
Monitoring: Ensures compliance with clearance conditions during construction and operation.
Note: India ranks last in air quality for human health, as per the World Economic Forum.
Key Elements of the EIA Cycle
Screening
Screening Criteria: Investment scale, development type, and location determine the requirement for environmental clearance.
Regulatory Notifications: Projects need clearance if covered under EIA notifications.
Scoping
Terms of Reference: Established through consultant, proponent, and agency discussions.
Sectoral Guidelines: MoE&F’s guidelines dictate significant issues for EIA studies.
Baseline Monitoring: Post identification of impact areas, baseline status is assessed for predicted changes.
Baseline Data
Existing Status: Collected primary data describes the environmental status, supplemented with secondary data when available.
Note: India has the worst air pollution globally according to the World Economic Forum, ranking 132nd in “Air effects on human health.”
Impact Prediction
Air: Changes in ambient levels, effects on health, materials, and vegetation.
Noise: Impact on fauna and human health due to equipment noise and vehicle movement.
Water: Availability, quality changes, sediment transport, saline water ingress.
