NOC from Pollution Control Board in India – CTE & CTO Approval Guide (2026)

Introduction to NOC from Pollution Control Board

Every industry in India needs a No Objection Certificate(NOC). This certificate must come from the Pollution Control Board (PCB). You must complete it before starting any work.
This helps follow environmental laws like the Water (Prevention and Control of Pollution) Act, 1974. It also includes the Air (Prevention and Control of Pollution) Act, 1981, and the Environment Protection Act, 1986.
The two key approvals required are:

- Consent to Establish (CTE) – Permission to set up the industry.
- Consent to Operate (CTO) – Authorization to begin commercial operations.
Industries that fail to obtain these consents risk heavy fines, legal action, or even shutdowns. This guide explains how to apply for an NOC from the Pollution Control Board. It covers eligibility and why it is important for your business.

What is Consent to Establish (CTE)?

Consent to Establish (CTE) is the initial approval required before constructing or establishing an industrial unit. The State Pollution Control Board (SPCB) or Pollution Control Committee (PCC) grants this permission after assessing potential environmental impacts.

Key Features of CTE

✔ Mandatory for New Industries – Required before land acquisition or construction.

✔ Project-Specific Conditions – May include pollution control measures.

✔ Validity Period – Typically 1 to 5 years, depending on the project.

When Do You Need CTE?

- Before purchasing land for industrial use
- Prior to applying for construction permits
- Before installing machinery or infrastructure

Industries Exempt from CTE

- Small-scale industries with minimal pollution (as classified by SPCB)
- Home-based businesses with no hazardous waste

What is Consent to Operate (CTO)?

Consent to Operate (CTO) is the final clearance needed to start commercial operations. It ensures that the industry complies with pollution control norms before production begins.

Key Features of CTO

✔ Required Before Production – Must be obtained after CTE but before operations.

✔ Renewable Every 5-10 Years – Regular compliance checks are mandatory.

✔ Involves Inspections – The PCB verifies pollution control systems before approval.

Why is CTO Important?

- Legal Requirement – Operating without CTO is a punishable offense.
- Environmental Responsibility – Ensures adherence to sustainable practices.
- Business Reputation – Builds trust with clients and investors.

Industries That Need CTO

- Factories emitting air/water pollutants
- Waste treatment plants
- Large commercial establishments (hospitals, hotels)
 Key Differences Between consent to establish and consent to operate

Can CTE & CTO Be Applied Together?

Some states allow combined applications, but they grant approvals in phases

Penalties for Non-Compliance

- Fines up to ₹1 lakh per day
- Imprisonment under the Environment Protection Act
- Business closure orders
