NOC From Pollution Control Board

If you are planning on starting any business which could potentially generate pollutants such as chemical waste, detergent washing, fly ashes, smoke emissions (including cooking smoke), medical waste to name a few – also referred to as trade effluents, then you will need to make an application to the respective State Pollution Control Board and obtain a pollution license/Certificate or a consent to establish your business.

This consent to establish (let’s call it CTE) will have to be obtained prior to commencement of construction or any similar activities to start the business. Once the construction/ set up phase is complete, then you will have to apply and obtain a consent to operate (abbreviated as CTO). This CTO will usually be valid for a period of 5 years, which may vary State to State.

Every state board is the authority to secure this form of NOC Pollution Control Board. A manufacturer would require getting the Consent to Operate (CTO) and Consent to Establish (CTE). Once the consent period expires, it is essential to renew the Consent to Operate from the Pollution Control Board. Such consent is required in order to ensure that the institution or the industry is operating properly. Such consent would also ensure that the pollutants are not emitted as per the required amounts.

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.
  • Providing and organising different forms of pollution control programs.
  • Carrying out Research and Development Activities.
  • Publication of Technical and Statistical Data.
  • Implementing Schemes at a National Level.

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. This categorisation would be under the applicable Water (Prevention & Control of Pollution) Act, 1974, Air (Prevention & Control of Pollution) Act, 1981.

The following category of industries would be classified:

category under NOC Control Board

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.

Eligibility Criteria for Securing NOC Pollution Control Board

The following is the eligibility criterion which has to be sufficed by the applicant for securing the NOC from the Pollution Control Board:

eligibility criteria

Hence the applicant has to satisfy the above requirements and eligibility criteria in order to be compliant with the requirements of NOC pollution control board.

What Industries typically requires Pollution Consent?

The Ministry of Environment, Forest and Climate Change (MoEFCC) has developed the criteria of categorization of industrial sectors based on the Pollution Index which is a function of the emissions (air pollutants), effluents (water pollutants), hazardous wastes generated and consumption of resources.

See the list of industries that the Central Pollution Control Board has specified, as requiring a pollution license in the red, orange, green and white category. As the name suggests, the Red category industry has the highest pollution index, such as big manufacturing industries, large hotels, hospitals, etc. The orange category is a relatively medium-sized enterprise, which still generates comparatively high levels of pollutants. Whereas the Green category is the set of the industry with low pollution Index. And finally the white category, which is practically non-polluting.

Exempted Industries from Obtaining the Pollution Consent
