NOC Pollution Control Board- An Overview

CTO (Consent to Operate) is required for running an industry dealing with pollutants and hazardous wastes. Therefore it is crucial to renew the licence for consent to operate from NOC Pollution Control Board. There is a separate CTO for different forms of industries. Such industries would include the water and the air industry. Usually the requisite consent to operate from the NOC pollution control board is obtained under the Water Act, 1974 and Air Act, 1981. Apart from this the industry must comply with the rules related to authorisation under the Hazardous & Other Waste (Management & Transboundary Movement) Rules, 2016.

The manufacturer has to go to the requisite NOC pollution control board in order to secure this form of consent to operate. However, any form of manufacturing industry or any other commercial establishment would also require securing this consent to operate before starting operations.

If the above consent expires after a particular period of time, then the entrepreneur has to mandatorily file the renewal of the NOC pollution control board. Under different forms of environmental laws, Consent to Operate (CTO) is required for production and manufacturing activities. To secure consent to operate licence, the proprietor of the industry must submit the required permits with the fees and the CTO FORM.

Types of NOC Pollution Control Board

There are two forms of clearance as required by the requisite pollution control board:

  • Consent to Establish Consent to Establish is known as the CTE. This form of consent is required from the authority in order to establish or carry out any manufacturing industries. This is something related to the primary permission from the requisite authority to operate any form of air/water or noise pollution industry.
  • Consent to Operate The second form of consent is known as the consent to operate (CTO). This consent would be required in order to ensure that the industry is maintaining standards related to operation. All industries require this form of consent to operate.

Main Functions of the Central Pollution Control Board (NOC Pollution Control Board)

The main functions of the Central Pollution Control Board:

  • Ensuring and advising the government on matters related to air pollution, water pollution and sound pollution.
  • Co-ordinating with the state pollution control body to ensure compliance is maintained.

Category of Industries under NOC pollution Control Board

The Central Environmental Protection Board and pollution control authorities have categorised different industries based on the amount of pollution.

The following category of industries would be classified:


If an industry is coming under the Red, Orange or Green Category then the requirement for Consent to Establish and Consent to Operate must be secured from the pollution control authorities under the Water (Prevention & Control of Pollution) Act, 1974, Air (Prevention & Control of Pollution) Act, 1981.

If an industry or manufacturer falls under the White Category then the requirement for securing the consent to operate and the consent to establish is not required. Hence manufacturers in these categories do not need to secure the CTO and the CTE under the respective environment pollution control acts.

An industry under the white category would have to just intimate the State Pollution Control Authorities. This would be the NOC from the state pollution control board.
