CPCB and State Pollution Control Boards: CTE and CTO Explained

The Central Pollution Control Board (CPCB) sets national pollution norms, while State Pollution Control Boards handle most day-to-day approvals for industries. Two consents matter: Consent to Establish (CTE) before you build or set up, and Consent to Operate (CTO) before you start running.

Why it matters

Factories, processing units and many service businesses cannot start without these consents. Skipping them can lead to closure notices. Many owners first hear about this when a bank or buyer asks for a pollution NOC.

How the system works

• CPCB: a central body under the Water and Air Acts that advises on standards and coordinates the state boards.
• State boards: receive applications, inspect and grant or refuse consent for units in their state. In Haryana, for example, see HSPCB consent to establish and operate.
• CTE then CTO: the first is for setting up, the second for operations once the unit is ready.

Other approvals that may apply

Big projects may also need environmental clearance from the environment ministry before CTE. Waste handlers, housing and commercial complexes may need solid waste management authorization.

Getting it right

Check your activity’s category with the state board, because requirements differ for polluting and low-impact units. Keep site plans, process details and land papers ready. Renew CTO before it expires.

Common mistakes

• Starting construction or production before the consent arrives.
• Treating CTE as permanent permission to run.
• Letting CTO lapse because no reminder came.
• Giving process details that later differ from what the unit actually does.
