Pollution control law in India rests on three main pillars: the Water Act of 1974, the Air Act of 1981 and the Environment (Protection) Act of 1986. Between them, they decide who needs permission, what standards apply and what happens when the standards are broken.
We advise industries on staying within these rules, act for people affected by air, water and noise pollution, and handle the disputes that follow, from board notices to NGT appeals.
हिंदी में सारांश

Is this your situation?
- Your unit needs consent or has received an emission or effluent notice
- Air pollution from a nearby unit, kiln or construction site is affecting you
- Effluent is reaching a river, drain or groundwater
- Noise from loudspeakers, generators or machinery is disturbing you
- Your DG set or boiler does not meet the current norms
- You need advice on online monitoring requirements
The main tools of pollution law
Consent
Permission from the board to establish and operate a unit that discharges or emits.
Standards
Limits for effluent and emissions set under the Environment (Protection) Rules and in the consent.
Directions
Power of the board to close, regulate or cut power and water to a unit.
Penalties
Monetary penalties, now largely decided by adjudicating officers after recent amendments.
Monitoring
Online continuous monitoring for many large and polluting units.
Noise limits
Zone-wise day and night limits under the Noise Rules.
Noise limits under the Noise Rules, 2000
Noise limits depend on the type of area. Daytime is 6 am to 10 pm. Loudspeakers and public address systems generally cannot be used at night without permission, and permission for limited relaxation is allowed only on specified occasions.
| Area | Day limit, dB(A) | Night limit, dB(A) |
|---|---|---|
| Industrial | 75 | 70 |
| Commercial | 65 | 55 |
| Residential | 55 | 45 |
| Silence zone (near hospitals, schools, courts) | 50 | 40 |
Penalties after the 2023 and 2024 amendments
The Jan Vishwas (Amendment of Provisions) Act, 2023 and the Water (Prevention and Control of Pollution) Amendment Act, 2024 replaced many criminal offences in the Air, Water and Environment (Protection) Acts with monetary penalties decided by adjudicating officers. Some serious violations and non-payment of penalties still carry criminal consequences. If you face proceedings, check which version of the law applies to the period in question.
When pollution affects you
A complaint to the board is the starting point, followed by an NGT application if nothing happens. For noise, the police and district administration have direct powers under the Noise Rules. In Delhi NCR, air pollution complaints can also go to the Commission for Air Quality Management.

Frequently Asked Questions
Is pollution still a crime in India?
Many violations under the Air, Water and Environment (Protection) Acts now lead to monetary penalties instead of prosecution, after the 2023 and 2024 amendments. Some acts and non-compliance with orders can still lead to criminal action.
What are the noise limits at night in a residential area?
45 dB(A) between 10 pm and 6 am under the Noise Rules, 2000.
Who sets effluent and emission standards?
General standards are in the Environment (Protection) Rules, 1986, and the board can set stricter limits in the consent.
Can a board cut off electricity to a unit?
Yes. Under Section 33A of the Water Act and Section 31A of the Air Act, the board can direct closure and stoppage of power and water.
Do small units need consent?
It depends on the category. White category units are generally exempt, but most others need consent.
Can I complain about noise from a religious place or event?
Yes. The Noise Rules apply to everyone. The police and district administration are the authorities to approach.
