Q6.Environmental Impact Assessment studies are increasingly undertaken before a project is cleared by the Government. Discuss the environmental impacts of coal-fired thermal plants located at coal pitheads.

Environmental Impact Assessment (EIA) is crucial for evaluating and mitigating potential ecological damage from large industrial projects like thermal power plants.

Locating thermal plants at coal pitheads reduces transportation costs. However, this concentrates environmental burdens of both mining and power generation locally.

Air Pollution

• Significant emissions of SOx, NOx, PM, CO2, and heavy metals (e.g., mercury), severely degrading local air quality and human health.

Water Stress and Pollution

• High water consumption for cooling causes regional water scarcity. Thermal pollution and ash pond leachate contaminate aquatic ecosystems.

Solid Waste Management

• Massive fly ash and bottom ash generation requires extensive land for disposal, leading to land degradation and soil contamination.

Habitat and Biodiversity Loss

• Land acquisition for plant, ash ponds, and mining results in deforestation, habitat destruction, and biodiversity loss.

EIA is vital for balancing India's energy demands with environmental sustainability, ensuring comprehensive assessment and mitigation for these concentrated impacts.
