Introduction: Kalai-II Hydel Project and Environmental Oversight

The Kalai-II hydel project in Arunachal Pradesh, proposed in 2023 by the Arunachal Pradesh Energy Department, aims to generate approximately 96 MW of electricity with an estimated investment of INR 600 crore. The project is part of the state's broader hydropower development strategy, leveraging Arunachal Pradesh's vast untapped potential of 50,000 MW, of which only 5% has been harnessed (Ministry of Power, 2023). However, the project proposal notably omits any mention of the endangered bird habitat, specifically the presence of the White-winged Duck (Cairina scutulata), a Schedule I species under the Wildlife Protection Act, 1972. This omission raises significant concerns about compliance with environmental safeguards mandated under Indian law and threatens the ecological balance in a biodiversity-rich region.

Legal Framework Governing Environmental Safeguards in Hydropower Projects

The Environment Protection Act, 1986 mandates environmental impact assessments (EIA) for projects potentially affecting ecological balance, particularly under Sections 3 and 5. The Kalai-II proposal’s failure to address endangered bird habitats contravenes this requirement. The Wildlife Protection Act, 1972 (Sections 2 and 38V) explicitly protects Schedule I species like the White-winged Duck and their habitats, requiring stringent conservation measures during project planning. Additionally, the Forest Conservation Act, 1980 (Section 2) regulates diversion of forest land for non-forest use, a likely scenario given Arunachal Pradesh’s dense forest cover. The National Green Tribunal Act, 2010 empowers the NGT to adjudicate environmental disputes, providing a judicial mechanism to enforce compliance. Article 48A of the Constitution directs the State to protect and improve the environment, a fundamental duty that the project proposal undermines. Landmark Supreme Court rulings, notably T.N. Godavarman Thirumulpad v. Union of India (1996), have emphasized strict scrutiny of forest and wildlife habitats in development projects, reinforcing the need for comprehensive EIAs.

Economic Considerations of the Kalai-II Hydel Project

The project promises to add 96 MW to Arunachal Pradesh’s hydropower capacity, contributing to India’s overall 12% hydropower share in electricity generation (CEA, 2023). It forecasts creation of 500 direct construction jobs and 150 permanent positions post-commissioning (Arunachal Pradesh State Government report, 2023). However, the ecological damage from ignoring endangered species habitats risks undermining eco-tourism, which currently generates approximately INR 50 crore annually in the region (Arunachal Tourism Department, 2022). Environmental non-compliance can also trigger litigations and delays, inflating project costs by 15-20% and extending timelines by 2-3 years (Economic Survey 2023), thereby offsetting economic gains.

Institutional Roles and Responsibilities

• Ministry of Environment, Forest and Climate Change (MoEFCC): Grants environmental clearances and oversees EIA approvals.
• Central Electricity Authority (CEA): Conducts technical and economic appraisal of power projects.
• Arunachal Pradesh State Pollution Control Board (APSPCB): Monitors local environmental compliance and enforcement.
• Wildlife Institute of India (WII): Provides scientific data on endangered species and habitats.
• National Green Tribunal (NGT): Adjudicates environmental disputes and enforces legal compliance.
• Arunachal Pradesh Energy Department: Responsible for project implementation and local governance.

Critical Gap: Environmental Safeguards in Kalai-II Project

The absence of explicit consideration for endangered bird habitats in the Kalai-II proposal highlights a systemic failure to enforce mandatory EIA disclosures and integrate biodiversity conservation into hydropower planning. This gap stems from prioritizing energy generation targets over ecological sustainability, risking irreversible damage to Arunachal Pradesh’s rich biodiversity. Such oversight contravenes legal mandates and undermines long-term sustainable development goals.

Way Forward: Integrating Environmental and Developmental Objectives

• Mandate comprehensive and transparent EIAs including detailed biodiversity assessments, especially for Schedule I species.
• Strengthen inter-institutional coordination between MoEFCC, WII, APSPCB, and local governance bodies for monitoring and enforcement.
• Incorporate community consultations and traditional ecological knowledge in project design to ensure social and environmental acceptability.
• Adopt best practices from Bhutan’s hydropower model emphasizing biodiversity conservation alongside economic growth.
• Utilize NGT’s judicial oversight to enforce compliance and expedite dispute resolution to avoid cost escalations.
