Pollution NOC from State Pollution Control Board
All industries are classified into four categories: red, orange, green, and white. Industries that pollute the air, and water, or generate hazardous waste are covered under the consent management system.
Under this system, industries must obtain a prior no objection certificate (NOC) from the state Pollution Control Board (SPCB) before setting up plant and machinery and operating equipment that could pollute the environment.
Pollution NOC refers to the pollution control certificates that are required for the establishment and operation of an industrial unit. These certificates are generally called CTE (Consent to Establish) and CTO (Consent to Operate).
In some states, such as Uttarakhand, it is called CCA NOC because the permission to operate, hazardous waste authorisation, and E-waste authorisation is granted together.
Pollution control certificates are generally covered by the provisions of the Air (Prevention and Control of Pollution) Act, 1981, the Water (Prevention and Control of Pollution) Act, 1974, and the Environment Protection Act, 1986.
The Industrial units or projects can be established or operated if they have obtained a pollution control certificate from the State Pollution Control Board.
Factories or Industries that operate without a pollution license from the Pollution Control Board are considered illegal.
The Pollution Control Board is authorized to cut off the water and electricity supply of any defaulting unit under the provisions of the Air Act, 1981, and the Water Act, 1974.
