....nvironmental Impact Assessment (EIA) of a Thermal Power Plant (TPP).<br>By: - YAGAY andSUN<br>Environmental Law<br>Dated:- 23-4-2025<br>🏭 Environmental Impact Assessment (EIA) of a Thermal Power Plant (TPP). Here's a structured explanation of the Environmental Impact Assessment (EIA) of an Industrial Thermal Power Plant, in line with Indian regulations, especially the EIA Notification, 2006 (as amended) under the Environment (Protection) Act, 1986. 📘 Definition: EIA is a process to evaluate the environmental, social, and economic impacts of a proposed thermal power project before granting environmental clearance. 📑 Legal Framework * Governed under the EIA Notification, 2006 (MoEFCC) * Thermal Power Plants (&g....

....e;20 MW) fall under Category A → require clearance from the MoEFCC at the central level. * Projects <20 MW may be Category B → assessed at the State Environment Impact Assessment Authority (SEIAA). 🔁 Stages of EIA Process 1. Screening (Not needed for Category A) Determines if a full EIA is required (for Category B projects). 2. Scoping * Terms of Reference (ToR) issued by MoEFCC or SEIAA. * Specifies the focus areas for detailed study: air, water, soil, biodiversity, etc. 3. Baseline Data Collection * Monitoring over a one-season period (excluding monsoon). * Parameters: * Air Quality (SO₂, NOx, PM10, PM2.5) * Water Quality (surface & groundwater) * Soil Quality * Noise levels * Ecology & Bio....
