Environmental Impact Assessment (EIA) in India: Process, Committees and Monitoring

What is Environmental Impact Assessment?

Environmental Impact Assessment (EIA) is an important management tool that ensures optimal use of natural resources for sustainable development. The Ministry of Environment, Forest and Climate Change (MoEFCC) page on EIA says the exercise began in India in 1978-79 with the impact assessment of river valley projects.

The scope was later widened to industrial projects, thermal power projects, mining schemes and other development sectors. The Ministry page says EIA is now mandatory under the Environment (Protection) Act, 1986, for 29 categories of development activities with an investment of Rs 50 crore and above.

Why it matters: an EIA brings environmental cost into the planning stage, before money is spent and land is cleared. It lets decision makers compare the benefit of a mine, factory or dam with its effect on air, water, land and people, and it gives a record against which the project can later be checked. For a GS-III answer, present EIA as a preventive tool, not a punishment tool, and link it to sustainable development.

Which committees appraise projects?

To get multidisciplinary inputs, expert appraisal committees have been formed for these sectors:

Each committee brings experts of different fields together, so a single project is judged on technical, ecological and social grounds and not by one department alone. This multidisciplinary approach is the main strength of the appraisal stage.

• Mining projects
• Industrial projects
• Thermal power projects
• River valley, multipurpose, irrigation and hydroelectric projects
• Infrastructure development and miscellaneous projects
• Nuclear power projects

How does the appraisal process work?

1. Project authority applies with documents listed in the EIA notification ↓
2. Technical staff of the Ministry scrutinise the application ↓
3. Appraisal committee evaluates the project impact, with site visits if needed ↓
4. Committee recommends approval or rejection ↓
5. Ministry processes the decision ↓
6. Environmental clearance with safeguards, then monitoring

For site-specific projects such as mining, river valley and ports and harbours, the Ministry page describes a two-stage clearance: the project authority must get site clearance before applying for environmental clearance. This is meant to avoid ecologically fragile and environmentally sensitive areas. Where the proponent gives complete information, a decision is taken within 90 days. The two stages matter because a wrong site cannot be fixed later by safeguards alone; avoiding fragile areas at the start is cheaper and safer than repairing damage afterwards.

How are cleared projects monitored?

Clearance is not the end of the matter. The Ministry page treats monitoring as part of the same system, with the stated aim of checking that the suggested safeguards are adequate and correcting course where needed. Environmental clearance is given subject to the implementation of the prescribed safeguards. According to the Ministry page, approved projects are monitored by six regional offices of the Ministry, located at Shillong, Bhubaneswar, Chandigarh, Bangalore, Lucknow and Bhopal.

• The project authority reports progress on the conditions and safeguards every six months.
• Officers and expert teams make field visits to collect and analyse performance data.
• In case of serious deviations or poor response, the matter is taken up with the State Government concerned.
• Changes in project scope are identified to check whether the earlier decision needs review.
