Some projects cannot start at all, not even site preparation, until they receive prior environmental clearance under the Environment Impact Assessment Notification, 2006. The notification lists the projects and activities that need EC: mining, thermal power, river valley projects, many industries such as cement, metals, chemicals and pharmaceuticals, infrastructure like highways, ports and airports, and large building and township projects. Category A projects are appraised by the Union Ministry of Environment, Forest and Climate Change; Category B projects by the State Environment Impact Assessment Authority.
EC is a demanding process with studies, public consultation for many projects, and appraisal by expert committees, followed by conditions that last for the life of the project. The Supreme Court, in its July 2026 decision in Vanashakti v Union of India, reaffirmed that prior EC is mandatory and ended the open-ended route for post-facto clearance under a 2021 office memorandum. This page explains who needs EC, how the process works, how long it takes and what happens after clearance.
हिंदी में सारांश
खनन, ऊर्जा, सीमेंट, रसायन, हाईवे, बंदरगाह और बड़े बिल्डिंग प्रोजेक्ट जैसे सूचीबद्ध प्रोजेक्ट शुरू करने से पहले EIA अधिसूचना, 2006 के तहत पर्यावरण मंज़ूरी (EC) ज़रूरी है। कैटेगरी A के लिए पर्यावरण मंत्रालय और कैटेगरी B के लिए राज्य स्तरीय प्राधिकरण (SEIAA) मंज़ूरी देते हैं; आवेदन PARIVESH पोर्टल पर होता है। सुप्रीम कोर्ट ने जुलाई 2026 में दोहराया कि पहले से EC अनिवार्य है।
Is this your situation?
- You are planning a mine, industrial project or infrastructure project
- Your building or township project has a large built-up area
- You want to expand an existing project that holds EC
- You have started work and are unsure whether EC was needed
- Your EC application is stuck at screening, scoping or appraisal
- You have received a show-cause notice for violating EC conditions
- You are buying a project and want to check its EC status
EC at a glance
Category A
Appraised by an Expert Appraisal Committee and decided by MoEFCC.
Category B
Appraised by the State Expert Appraisal Committee and decided by the SEIAA; B1 projects need an EIA report and usually a public hearing, B2 projects do not.
Four stages
Screening (for B projects), scoping (terms of reference), public consultation and appraisal.
PARIVESH
Applications, documents and decisions are handled online on the PARIVESH portal.
Integration with CTE
Since November 2024, units with EC do not need a separate Consent to Establish from the pollution board.
After clearance
Conditions must be followed for the life of the project, with six-monthly compliance reports.
How the EC process works
Check applicability
Find your project in the Schedule to the EIA Notification and confirm the category and thresholds.
Screening
For Category B projects, the SEAC decides whether the project is B1 or B2.
Scoping
The appraisal committee sets terms of reference for the EIA study. Standard terms of reference apply to many sectors.
EIA study and public consultation
An accredited consultant prepares the EIA report; a public hearing is held by the pollution board for projects that need it, and written comments are invited.
Appraisal
The committee examines the final EIA report, public hearing outcomes and replies, and recommends grant or rejection.
Decision and conditions
The regulatory authority grants or refuses EC, with specific and general conditions.
The Vanashakti rulings and post-facto clearance
For years, projects that started without EC sought clearance after the event through a 2017 notification and a 2021 office memorandum. In May 2025, a two-judge bench of the Supreme Court struck these down; in November 2025, a three-judge bench recalled that decision; and on 29 July 2026, the three-judge bench delivered its final decision. It held that prior EC under the 2006 Notification is mandatory; upheld the 2017 notification, which gave violators a one-time six-month window, as a narrow and time-bound exception; and quashed the 2021 office memorandum, with prospective effect. Clearances already granted under it remain unless individually challenged, but fresh applications under the 2021 route are barred.
The practical message is plain: no work should start on a project listed in the Schedule before EC is granted. For projects already in violation, the options are now very limited and need careful legal advice.
After clearance: conditions and compliance
EC comes with conditions on pollution control, green belt, water use, waste, monitoring and community measures. The project must file six-monthly compliance reports, and the regional office of MoEFCC or the state authority can inspect. Breach of conditions can lead to directions under Section 5 of the Environment (Protection) Act, penalties after the Jan Vishwas amendments, and in serious cases suspension or revocation. EC also has a validity period, set by the notification for different types of projects, within which construction or operations must begin. See EC compliance reports.

How we work
We are a litigation and advisory practice led by Advocate BK Singh, with offices in Dwarka (New Delhi) and Vaishali (Ghaziabad). This is what you can expect:
- Applicability settled first: thresholds and category checked against the Schedule.
- Legal oversight of the process: with your EIA consultant.
- Public hearing preparation: issues anticipated and answered.
- Conditions reviewed: before you accept them.
- Written fee terms: agreed stage by stage, never linked to the outcome.
Mistakes we see with EC
- Starting site work before EC
- Splitting a project to stay under thresholds
- Ignoring forest or wildlife approvals needed alongside EC
- Treating EC conditions as a formality
- Missing six-monthly compliance reports
An industrial project in Haryana
Here's a made-up example. A company planned a chemical manufacturing project in a Haryana industrial estate. It had bought land and wanted to start foundations while studies were completed.
We advised that the project was listed in the Schedule and needed prior EC, and that no construction could begin. The EIA study and public hearing were completed, and the SEIAA granted EC with conditions on effluent treatment and green belt. Because the company held EC, it did not need a separate CTE, and moved directly to construction.
A project that started too early
Here's a second made-up example. A developer had started excavation for a project that needed EC, believing it could apply under the 2021 post-facto route. After the July 2026 decision, that route was no longer available for fresh applications.
We advised stopping work at once, assessing the environmental impact of what had been done, and engaging with the authority on the legal position. The developer's exposure to penalties and compensation depended on the extent of work done and its impact, and the project timeline was significantly delayed.
The public hearing
For Category A projects and Category B1 projects, other than those exempted, the EIA process includes public consultation. The public hearing is conducted by the state pollution control board with the district administration at or near the project site. Notice must be published in newspapers, including one in the local language, giving at least thirty days for the public to attend and respond, and the draft EIA report and summary must be made available. The proceedings are recorded and video-graphed, and the minutes are sent to the appraising authority.
Project proponents sometimes treat the hearing as a formality. That is a mistake. Issues raised by villagers, residents and organisations at the hearing must be addressed in the final EIA report, and courts and the NGT have set aside clearances where the hearing was not properly conducted or concerns were ignored. Preparing for the hearing, with a clear summary in the local language and honest answers about water use, land, traffic and emissions, protects the clearance later.
How long EC lasts and what happens on a change of owner
An EC is valid for a fixed period from the date of grant, within which the project must start. The EIA Notification, as amended, sets the validity by type of project: ten years for most projects, with longer periods for river valley and mining projects. If the project does not start within the validity, the clearance lapses and a fresh application is required. Extensions are possible only as the notification allows, so track the validity date from day one.
If the project is sold, merged or transferred, the EC can be transferred to the new owner through an application on PARIVESH, with the transferee accepting all the conditions. Until the transfer is approved, the original holder remains answerable for compliance. Buyers of projects should check the EC, the compliance reports, and any pending violation proceedings before completing the transaction.
Who does what in the EC process
| Body | Role |
|---|---|
| Project proponent | Prepares Form 1 and studies, engages an accredited consultant, attends hearings, complies with conditions |
| Accredited EIA consultant | Prepares the EIA report and environmental management plan |
| State pollution control board | Conducts the public hearing; consulted on air and water issues |
| Expert Appraisal Committee (EAC) or SEAC | Appraises the project and recommends grant or rejection |
| MoEFCC or SEIAA | Decides and issues the EC |
| MoEFCC regional office and the board | Monitor compliance with EC conditions |
After you get EC
- Display the EC and its conditions as required
- File six-monthly compliance reports on PARIVESH
- Do not change the project's scale, layout or product mix without checking whether an amendment is needed
- Keep records of every condition, with photographs and test reports
- Track the EC validity date until the project starts
- Apply for transfer before or immediately after any change of ownership
