Tamil Nadu Pollution Control Board (TNPCB)- An Overview
In accordance with the Water (Prevention and Control of Pollution) Act, 1974, the Government of Tamil Nadu established the Tamil Nadu Prevention and Control of Water Pollution Board on February 27, 1982 (27-2-1982). (Central Act 6 of 1974). In 1983, the Board's name was changed to Tamil Nadu Pollution Control Board (TNPCB). It carries out the requirements of the Environment (Protection) Act of 1986, the Air (Prevention and Control of Pollution) Act of 1981, and the Water (Prevention and Control of Pollution) Act of 1974.
On February 27, 1982, the Tamil Nadu Pollution Control Board (TNPCB) was founded. It operates with a Chennai head office, eight zonal offices, and 38 district offices. The Chairman runs the Board office, Joint Chief Environmental Engineers run the Zonal offices, District Environmental Engineers run the 38 District offices, and Assistant Environmental Engineers run the three AEE offices. Additionally, five flying squads led by environmental engineers are in operation in the cities of Chennai, Erode, Salem, Tiruppur, and Vellore.
What Are the Objectives of the Tamil Nadu Pollution Control Board (TTNPCB) NOC?
- Pollution should be reduced as much as feasible at the source while also taking into account current technical developments, financial viability, and the responsiveness of the surrounding environment. This goal is achieved by establishing disposal standards and laws governing gaseous emissions.
- By selecting suitable locations for the construction of new industrial applications or estates, pollution can be lessened.
- One can significantly improve the state's ecology by implementing the laws into practice.
- Reduce water use and operational expenses by maximizing the recycling and reuse of commercial and wastewater discharge for agricultural and industrial purposes following adequate treatment. The approach also helps to prevent water contamination because there are fewer waste discharges into receiving bodies and water sources.
- Establishing policies and practices to maximize reuse, recycling, and disposal of hazardous waste.
- In order to develop research into and evaluation of pollution-related issues, promote the conduct of such research and involvement in such research.

What are the Functions of the Tamil Nadu Pollution Control Board (TNPCB) Registration?
The following are the primary duties assigned to the TNPCB under the Water (Prevention and Control of Pollution) Act of 1974 as well as the Air (Prevention and Control of Pollution) Act of 1981-
- To work with the Central Pollution Control Board to organize mass education programs and the training of anyone involved or planning to be involved in programs linked to the prevention, control, or reduction of water and air pollution.
- To develop the most effective, commercially viable treatment solution for trade effluents and sewage
- To check places where air pollution is controlled in order to evaluate the quality of the air there and to take action to prevent, control, or lessen air pollution there.
- To evaluate the efficiency of wastewater and trade treatment plants for effluents and to examine the plans and specs for corrective measures
- To provide state government with advice on any issue about the reduction of water pollution and air pollution, including prevention, control, and mitigation
- To gather and spread knowledge about water and air pollution, as well as ways to prevent, regulate, or lessen it.
- Inspecting industrial facilities, manufacturing processes, and any control devices, and guiding how to take action to prevent, control, or reduce air pollution
- To establish, alter, or annually revise regulations for sewage and commercial effluents, as well as for the release of any pollutants in the air into the air from any other origin and the emission of pollutants from industrial facilities and vehicles.
- To gather samples of trade effluents, sewage, and air pollution emissions, and to evaluate those samples for a set of parameters.
- Must carry out any additional duties that the Central or State Pollution Control Board may specify.
How Are Industries Categorized Under The Tamil Nadu Pollution Control Board (TNPCB) Certificate?
Several firms' operations have been restricted by notices published by the Ministry of Environment, Forestry, and Climate Change (MoEFCC). Industries were separated into Red, Orange, Green, and White categories to help decide where to locate these enterprises. Later, the use of this concept was expanded to other regions of the nation in order to achieve several goals, including the regulation of permission and the creation of regulations for the oversight and examination of firms. The size of the enterprises and resource use have been the main factors in categorizing processes.
Any industrial industry's Pollutant Index, or PI, is a number between 0 and 100; an increasing PI value indicates a heavier pollution burden from that sector. After numerous brainstorming sessions involving the CPCB, SPCBs, and MoEFCC, the following Range of Pollutant Index standard for defining industry sectors has been finalized.
- Red Category: Industries with a PI ranging from 60 or higher. Such an area consists of those units that emit a toxic level of pollutants and effluents are released. Industries falling in the red category are not permitted in ecologically sensitive or protected regions.
- Orange Category: Industries with a PI ranging from 41 to 59. Those industries that create high-level pollution but are considerably lesser than those in the red category fall in the orange category.
- Green Category: Industries with a PI ranging from 21 to 40. Those who do not create pollution to toxic levels but emissions from enterprises are at a moderate level are a part of the Green Category.
- White Category: Industries with a PI ranging 20 or lower. Such industries create low to no pollution. It is further not mandatory for industries under the white category to obtain a CTE or NOC.

Based on gross fixed assets, the TNPCB has further categorized industries as Large, Medium, and Small.

What Consent is Needed for a Tamil Nadu Pollution Control Board (TNPCB) NOC?
The TNPCB approves new sectors in two steps. Before an industry begins construction, consent to establish is granted based on the availability of the site, and consent to operate is granted following the installation of pollution prevention measures by the unit to meet regulations. The field officials of the Board regularly check each industry under their purview to determine whether the effluent and gas emission treatment procedures are adequate.
What is the Consent required under the TNPCB?
- Consent to Establish
According to the requirements of the Water (Prevention and Control of Pollution) Act of 1974 and the Air (Prevention and Control of Pollution) Act of 1981, all new intended projects (developmental and industrial) are required to obtain "Consent to Establish" (commonly known as a NOC) from the Tamil Nadu Pollution Control Board.
- Consent to Operate
According to the requirements of the Water (Prevention and Control of Pollution) Act of 1974 and the Air (Prevention and Control of Pollution) Act of 1981, all operating units and those starting operations after a NOC issued by the Board must obtain "Consent to Operate" from the Tamil Nadu Pollution Control Authority.
Procedure to Obtain a Tamil Nadu Pollution Control Board (TNPCB) Consent/NOC/License
The procedure for obtaining Consent to Establish (CTE) and Consent to Operate (CTO) in the State of Tamil Nadu dealt with the Tamil Nadu Prevention of Water Pollution Act,1969. Also, the provisions of the Board were formed in accordance with the Water (Prevention and Control of Pollution) Act, 1974, the Air (Prevention and Control of Pollution) Act, 1981, and Section 5 of the Air (P &CP) Act, 1981. The Project Proponent and Start-ups who are willing to run their business project must have to obtain consent before the establishment of the Project anywhere in the State of Tamil Nadu. All the Projects, Industries, Non-industries units have been categorized under four categories that are Red, Orange, Green, and White according to the range under which it comes in the Pollution Index and Pollution Potential for Consent management. Since the given date of the project which is already in Operation needs to obtain Consent to operate and there is no need to obtain Consent to Establish permission as such Projects are already established and might be in operation.
