EIA & EC

Entrepreneurs should know:

“Environmental Impact Assessment (EIA) & Environmental Clearance (EC)”

 

 

  1. What Is EIA (Environmental Impact Assessment)?

The Environmental Impact Assessment (EIA) is a scientific study and process that evaluates how a proposed project may affect the environment before it begins.

 

It identifies potential impacts on:

  • Air and water quality
  • Soil and land use
  • Flora and fauna
  • Waste generation and disposal
  • Noise, traffic, and nearby communities

 

  1. Key Points about EIA:
  • It is done before project approval.
  • Conducted by accredited environmental consultants.
  • Results in an EIA Report that includes an Environmental Management Plan (EMP).
  • May involve a public hearing, where community opinions are heard.

 

The EIA report forms the scientific foundation on which the concerned authority decides whether the project can proceed and under what conditions. EIA is the process of studying environmental impact of the project.

 

  1. What Is EC (Environmental Clearance)?

Environmental Clearance (EC) is the official approval or permission granted by the competent authority, either by the State Environment Impact Assessment Authority (SEIAA–West Bengal) or the Ministry of Environment, Forest and Climate Change (MoEF&CC).

 

It is based on the findings of the EIA study and public consultation.
Only after receiving this clearance can a project legally start construction or production.

 

  1. Key Points about EC:
  • It is granted after EIA and appraisal.
  • Contains specific conditions for pollution control, waste management, and resource use.
  • Requires periodic submission of compliance report to the authorities.

 EC is the approval, received after the EIA is accepted.

 

  1. Relationship between EIA and EC:
  2. EIA is a study or process whereas EC is the permission or clearance.
  3. The purpose of EIA is to identify and evaluate environmental risk whereas EC is the approval with conditions.
  4. EIA is conducted before project is finally approved whereas EC is granted after EIA approval before construction.

EIA leads to EC. Without EIA, one cannot apply for or receive Environmental Clearance.

 

  1. Category for EIA and EC

All the projects listed in the EIA Notification 2006, are categorized into two broad categories, based on the extent of potential impacts and sensitivity of the candidate sites –

 

Category A – Appraisal will be done by the Central Level Expert Appraisal Committee (EAC) and Clearance will be given by MoEF, GoI. EIA is mandatory.

 

Category B – Appraisal will be done by the State Level Expert Appraisal Committee (SEAC) and Clearance will be given by State Environmental Impact Assessment Agency (SEIAA), except in case of special conditions and general conditions. Sub grouped as Category B1 (EIA necessary) and Category B2 (EIA not necessary).

 

  1. The EIA–EC Process:

Category A: Appraisal Authority is Ministry of Environment, Forest and Climate Change (MoEF&CC), Government of India.

 

Process summary-

  1. a) Screening not needed – all projects require EIA.
    b) Terms of Reference (ToR) issued by MoEF&CC.
    c) EIA study and public hearing
    d) Expert Appraisal Committee (EAC) appraises the report.
    e) Environmental Clearance (EC) granted or rejected with conditions.

 

Category B: Appraisal Authority is State Environment Impact Assessment Authority (SEIAA – West Bengal)

 

Process summary-

  1. a) Screening by State Expert Appraisal Committee (SEAC) to classify as B1 or B2.
    b) B1– Full EIA and public hearing required.
    c) B2 – No EIA or public hearing (simplified process).
    d) SEAC reviews report / information.
    e) SEIAA issues EC with conditions or declines clearance.

 

After obtaining Environmental Clearance from the concerned authority (MoEF&CC / SEIAA as applicable), the project proponent shall apply to the State Board in prescribed format, along with the copy of Environmental Clearance, for obtaining Consent to Establish. The Consent to Operate comes into play once the project is ready to function.

 

  1. In Conclusion:

For every entrepreneur, Environmental Impact Assessment (EIA) and Environmental Clearance (EC) serve as the twin foundations of responsible industrial development. EIA enables a comprehensive evaluation of how proposed activities may affect the natural and social environment, ensuring that potential risks are identified and mitigated at the planning stage. EC, in turn, provides the formal authorisation that allows the project to proceed, subject to the prescribed environmental safeguards and monitoring obligations. Together, these two mechanisms uphold the principle that economic growth and environmental stewardship must advance hand in hand-ensuring a future that is both industrially progressive and ecologically balanced.
