Pollution Control Boards (Central and State)

Environment & Ecology › Environmental Institutions and Schemes in India · Topic 19.1

The Central Pollution Control Board (CPCB) and State Pollution Control Boards (SPCBs) are statutory bodies for the prevention and control of water and air pollution in India. The CPCB was constituted on 23 September 1974 under the Water (Prevention and Control of Pollution) Act, 1974, was given powers under the Air (Prevention and Control of Pollution) Act, 1981, and acts as a field formation of the Ministry of Environment, Forest and Climate Change under the Environment (Protection) Act, 1986; its headquarters are in Delhi. Its main functions are to advise the Central Government, coordinate and guide state boards, set national standards for water and air quality and emissions, collect and publish data, run the National Water Quality Monitoring Programme and the National Air Quality Monitoring Programme, conduct research and training, and carry out mass awareness. State Pollution Control Boards, and Pollution Control Committees in Union Territories, give or refuse consent to establish (CTE) and consent to operate (CTO) to industries, inspect units, take samples, enforce standards and file cases for violations. Industries are classified by pollution potential into Red, Orange, Green and White categories. The boards can issue directions, including closure and stopping of power and water supply, and use Online Continuous Emission and Effluent Monitoring Systems for 17 highly polluting categories of industry.

Where Does It Fit?

This is the first topic of the macro on environmental institutions and schemes in India. The pollution control boards are the main regulators, and the rest of the macro covers the other bodies and programmes. Previous topic: Mission Innovation (Clean Energy Initiative). Next topic: National Green Tribunal.

What Do the Central and State Boards Do?

Body	Role and powers
CPCB	Statutory body set up 23 September 1974; sets national standards; advises Centre; coordinates SPCBs; runs national monitoring networks; publishes reports
SPCBs	Statutory boards in each state; give or refuse consent; inspect and monitor; prosecute violators
Pollution Control Committees	Do the work of boards in Union Territories
Consent to Establish	Permission needed before setting up an industry that may pollute
Consent to Operate	Permission needed before starting operation, with conditions on discharge and emissions
Directions	Boards can issue directions, including closure, and stop electricity or water supply, under Section 18 of the Water Act and Section 31A of the Air Act
Monitoring	National Water Quality Monitoring Programme (since 1978) and National Air Quality Monitoring Programme (since 1984)

How Are Industries Classified and Monitored?

Red category: highly polluting industries with a pollution index of 60 or more
Orange category: moderately polluting, index 41 to 59
Green category: less polluting, index 21 to 40
White category: practically non-polluting, index up to 20, which need no consent
OCEMS: Online Continuous Emission and Effluent Monitoring Systems for 17 categories of highly polluting industries
Grossly polluting industries: units identified for strict action
Consent fee: boards collect fees under the Water Cess Act
Reports: annual reports on polluted river stretches and air quality

What Else Should You Remember?

Water Act, 1974: created the central and state boards; India’s first pollution law
Water Cess Act, 1977: taxes water use by industry to fund boards
Air Act, 1981: gave boards power on air pollution and air pollution control areas
1987 amendment: added noise as an air pollutant and increased powers
Composition: a full-time chairperson, a member secretary and nominated members from the government, local bodies and industry
CPCB chairman: appointed by the Central Government
Standards: CPCB prescribes NAAQS 2009 and effluent and emission standards, which SPCBs may make stricter
Polluted river stretches: CPCB identifies priority stretches based on BOD
Critically polluted areas: identified by the Comprehensive Environmental Pollution Index
Hazardous waste: boards authorise and monitor facilities
Bio-medical and e-waste: CPCB authorises and monitors compliance
Plastic waste: CPCB sets EPR guidelines
Environmental statements: industries submit an annual environmental statement
Public hearing: SPCBs organise EIA public hearings
Action against violators: closure directions, fines and prosecution; environmental compensation under polluter pays
Environment compensation: CPCB’s methodology for levying compensation was backed by the NGT
NGT oversight: appeals against board orders go to the NGT
Criticisms: staff and fund shortages, political influence and weak enforcement
Audit: reports show vacancies and low laboratory capacity
Technology: real-time data via CPCB portal
Link to previous: see Mission Innovation (Clean Energy Initiative)
Link to next: see National Green Tribunal
Link to law: see Sources and Causes of Water Pollution
Caution: category cut-offs and OCEMS lists were revised in 2016 and later, so check CPCB directions
Exam hint: learn 1974 for CPCB, the two Acts, CTE and CTO, and the colour categories
Public participation: citizens can complain to boards, and consent applications and reports are published online
Air quality network: hundreds of manual stations and continuous monitors form the national air monitoring network
Environmental clearance link: consent from the board is separate from environmental clearance under the EIA Notification
Penalty trends: the Jan Vishwas Act 2023 replaced some jail terms with fines under the Water and Air Acts
Water quality criteria: CPCB’s designated best use classes A to E guide river classification

Why Does It Matter for the Exam?

CPCB year: 1974
Acts: Water 1974, Air 1981
Permissions: CTE, CTO
Current affairs link: OCEMS and polluter pays
Common errors: saying the CPCB was created by the EPA 1986

As an analytical point, the boards are the front-line regulators, but they are often short of staff, funds and independence. Online monitoring, public data and the NGT’s oversight improve accountability.

Frequently Asked Questions

What is the Central Pollution Control Board?

The Central Pollution Control Board is a statutory body constituted on 23 September 1974 under the Water Act, 1974, and later given powers under the Air Act, 1981. It sets national standards, advises the Government, coordinates state boards, runs national monitoring programmes and publishes data, working under the Ministry of Environment, Forest and Climate Change.

What are consent to establish and consent to operate?

Consent to Establish is the permission from the State Pollution Control Board that an industry needs before it is set up. Consent to Operate is the permission needed before it begins operation, with conditions on discharge of effluent and emission of air pollutants. They are required under the Water and Air Acts and are renewed periodically.

How are industries categorised by pollution potential?

The CPCB classifies industries based on a pollution index into Red (highly polluting), Orange (moderately polluting), Green (less polluting) and White (practically non-polluting) categories. Red and Orange units face stricter scrutiny and consent conditions, while White units need no consent. Seventeen categories of highly polluting industries must install online emission and effluent monitoring.

What powers do pollution control boards have against violators?

Boards can inspect premises, take samples, issue directions, refuse or cancel consent, order closure of a unit, and stop the supply of power or water, and can file prosecutions in courts. They can also impose environmental compensation under the polluter pays principle, subject to appeal to the National Green Tribunal.

What are the main problems of pollution control boards?

Boards face shortages of staff, laboratories and funds, delays in consent, political and industry influence, and weak penalties, which limit enforcement. Reports have noted vacancies and poor monitoring in many states. Real-time online monitoring, transparent data and independent oversight by the NGT and courts help to improve performance.
