Pollution Control Boards — Central and State — Environmental Law Notes

Pollution Control Boards — Central and State

A pollution law is only as good as the body that enforces it — and India’s answer was to build one set of regulators for the whole system. The Boards created by the Water Act in 1974 were handed the Air Act in 1981 and later became the front-line authorities under the Environment (Protection) Act too. So when the Supreme Court in the Ganga Pollution case, M.C. Mehta vs Union of India (1988), wanted the river cleaned, it did not create anything new — it simply ordered the State Pollution Control Board to do the job the statute already gave it. Understand the Boards and you understand how all the pollution statutes actually bite.

Why one topic, and how it is built

This is the single most-asked essay in Unit 4, and the question comes in many disguises — “powers and functions of the Central Board”, “of the State Board”, “under the Water Act”, “under the Air Act”. The trick is that the answer is nearly the same every time, so learn one structure and re-point the opening line to whichever Board the paper names. Organise every answer as: constitution → powers → functions, and keep the two-tier picture clear:

Central Pollution Control Board (CPCB) — the national body: it advises the Centre, sets standards, and coordinates.
State Pollution Control Boards (SPCBs) — one per State: the ground-level regulators who run the consent system, inspect, sample and enforce.

A. Constitution and structure of the Boards

The Boards are constituted under ss. 3 and 4 of the Water Act, 1974 (s. 3 for the Central Board, s. 4 for the State Boards); the Air Act adopts the same Boards. Each Board is a body corporate. Its structure (Water Act s. 3(2) / s. 4(2)) is:

A Chairman — a person having special knowledge or practical experience of matters relating to environmental protection, nominated by the Government.
A full-time Member-Secretary — possessing qualifications, knowledge and experience of the scientific, engineering and management aspects of pollution control; he runs the Board’s day-to-day work.
Official members — not more than five officials nominated to represent the Government.
Non-official members — not more than three, from among persons with knowledge of agriculture, fishery, industry or trade.
Representatives of corporations — two persons representing the companies or corporations owned or controlled by the Government.
Members from the tier below — the CPCB has up to five persons representing the State Boards; each State Board has up to five persons representing the local authorities within the State.

Where two or more contiguous States (or a State and a Union Territory) need a shared regulator, a Joint Board can be constituted by agreement (Water Act ss. 13–14).

🔑 The composition is heavily weighted with official and interest-group members; commentators criticise this, saying a body meant to set objective water-quality standards is short on independent experts and vulnerable to Government pressure. Naming this critique lifts a “constitution” answer above a bare list.

B. Functions of the Central Board (CPCB)

Under s. 16 of the Water Act, the CPCB’s functions are national and coordinating. It:

advises the Central Government on any matter concerning the prevention and control of water pollution;
coordinates the activities of the State Boards and resolves disputes among them;
provides technical assistance and guidance to the State Boards and carries out investigations and research;
plans and organises training of pollution-control personnel;
organises a nationwide programme and a mass-awareness campaign;
collects, compiles and publishes technical and statistical data on water pollution; and
lays down, and modifies, standards for a stream or well.

Its air functions under the Air Act (s. 16 of that Act) mirror these for air quality.

C. Functions of the State Board (SPCB)

Under s. 17 of the Water Act, the State Board does at State level what the CPCB does nationally, but with the operational teeth. It:

plans a comprehensive programme for prevention and control of pollution and secures its execution;
advises the State Government on siting of industries;
inspects sewage and trade-effluent treatment plants and reviews plans and systems;
lays down effluent standards and evolves economical methods of treatment and disposal;
collects and disseminates information; and
grants, refuses or cancels consent under s. 25 — the power that makes it a real regulator.

D. Powers of the Boards

Functions say what the Boards do; powers say how they compel obedience. The key powers (Water Act; the Air Act has parallels) are:

Consent power (s. 25/26) — the master power: to allow, condition, refuse or withdraw permission to discharge. Under the Air Act the equivalent is s. 21.
Power to give directions (s. 33A, inserted 1988) — a Board may issue any binding written direction to any person, officer or authority, including the power to order closure, prohibition or regulation of an industry, or stoppage of electricity, water or any other service. This is the coercive power that lets a Board act without first running to a court.
Power of entry and inspection (s. 23) — an authorised person may enter any place to inspect and to seize records or plant for evidence.
Power to take samples (s. 21) — to take samples of effluent (and, under the Air Act s. 26, of emissions) following a prescribed procedure so the sample is admissible in court.
Emergency measures (s. 32) and injunction (s. 33) — in an emergency the Board may itself take remedial steps, and it may apply to a court (not below a judicial magistrate of the first class) to restrain apprehended pollution.
Power to execute work and recover cost (s. 30) — if a person fails to carry out required work, the Board may do it and recover the expense.

E. The State Air Laboratory (s. 28, Air Act)

A sample is useless unless it can be analysed reliably, so the Air Act, 1981 provides its own testing arm. Under s. 28, the State Government may, by notification, establish or specify a State Air Laboratory to carry out the functions entrusted to it under the Act. Under s. 29 the Government appoints Government Analysts for the laboratory. The scheme works like this: a Board officer takes an air sample under s. 26, sends it to the State Air Laboratory, and the Government Analyst’s signed report becomes the evidence used to prosecute the polluter. (The Water Act has the parallel Central and State Water Laboratories under ss. 51–52.) So the laboratory is the evidentiary backbone that turns an inspection into a conviction.

🧩 WORKED EXAMPLE — which Board, which power?

Facts. A paper mill on a river ignores repeated notices and keeps discharging effluent far above the permitted limit. The State Board wants it stopped at once, without waiting months for a court order.

Rule. The State Board grants and withdraws consent under s. 25; under s. 33A it may issue a binding direction including closure of the industry or stoppage of its power and water; it may take effluent samples under s. 21 and, in emergency, apply for an injunction under s. 33.

Apply. The Board first samples the effluent (s. 21) to prove the breach, then withdraws consent (s. 25) and issues a s. 33A direction ordering closure and cutting the mill’s electricity supply — no prior court order is needed for a s. 33A direction.

Conclusion. The State Board can shut the mill down immediately using s. 33A, backed by the sample evidence; the mill’s remedy is to appeal, not to keep polluting. This is exactly the enforcement muscle the 1988 amendment added.

Case Laws

M.C. Mehta vs Union of India (1988) (the Ganga Pollution case) — the Supreme Court directed the State Pollution Control Board, the Central Government and the district magistrate to enforce the Water Act against tanneries; the Board’s duty to act was affirmed.
Vijayanagar Educational Trust vs Karnataka State Pollution Control Board (2002) — on the “deemed consent” fiction: consent applied for is deemed granted if the Board says nothing within four months (s. 25(7)); the Karnataka High Court examined the Board’s handling of a delayed application.
Pollution Control Board, Assam vs Mahabir Coke Industry (2000) — a Board’s direction to close a polluting unit for operating without consent was upheld; industries cannot run in defiance of the consent regime.
