What is Consent to Operate?

Introduction

Consent to Operate (CTO) is a crucial environmental authorization that allows industrial units to commence production or operational activities in India. Issued by the State Pollution Control Board (SPCB), CTO certifies that the industry has implemented the required pollution control measures as per applicable regulations. Obtaining this consent is mandatory before starting operations in any facility that generates pollutants.

Meaning of Consent to Operate

Consent to Operate, often called the CTO certificate, is a legal permit granted after an industry completes construction and installs pollution control systems. Unlike Consent to Establish, which approves construction, CTO provides permission to begin functioning.

The full form of CTO is Consent to Operate, reflecting its purpose—to legally operate the facility under environmental laws.

Purpose and Importance of CTO

The main purpose of Consent to Operate is to confirm that the project has:

Fully implemented pollution control devices.
Complied with the conditions set during the Consent to Establish stage.
Put in place mechanisms to monitor and manage emissions and effluents.

The importance of Consent to Operate lies in:

Ensuring industries meet prescribed environmental standards before starting operations.
Protecting public health by controlling industrial pollution.
Enabling authorities to track compliance through regular inspections and reporting.

Without CTO, operating any industrial facility is illegal and may result in closure orders, penalties, or legal action.

CTO Under Environmental Laws

CTO is issued under the Water (Prevention and Control of Pollution) Act, 1974, and the Air (Prevention and Control of Pollution) Act, 1981, along with other applicable state regulations. The Pollution Control Board assesses:

Whether the industry has installed pollution control equipment.
Compliance with emission and discharge norms.
Arrangements for waste treatment and disposal.
Monitoring and reporting systems.

This consent ensures that environmental safeguards promised during project planning are genuinely implemented.

Difference Between Consent to Operate and Consent to Establish

While both consents are part of environmental clearance, they serve different purposes.

Consent to Establish (CTE)	Consent to Operate (CTO)
Approval to construct facilities	Approval to start operations
Obtained before setting up the project	Obtained after setup is complete
Focuses on project planning and design	Focuses on readiness and compliance

In other words, CTE allows you to build, CTO allows you to function.

When is Consent to Operate Required?

CTO is mandatory for:

Any new industrial facility starting operations.
Expanding existing production capacity.
Changing production processes that may impact pollution load.

Even small-scale units in regulated categories must secure CTO before operation.

Validity and Renewal

The validity of Consent to Operate varies by state and the pollution category of the industry. Typically:

Red category industries: Validity up to 5 years.
Orange category industries: Validity up to 10 years.
Green category industries: Validity up to 15 years.

Renewal applications must be filed before expiry to avoid disruption or penalties.

Role of Pollution Control Board

The State Pollution Control Board (SPCB) evaluates applications, inspects installations, and ensures compliance with:

Emission and discharge limits.
Waste management requirements.
Environmental monitoring protocols.

Industries must submit periodic reports and allow inspections to maintain validity.

Conclusion

Understanding what Consent to Operate means helps industries plan their compliance journey effectively. CTO is a critical step to ensure legal operation and demonstrate commitment to environmental responsibility.
