CPCB Notice Reply Counsel

If your unit or project faces an issue of state pollution control board notice (dpcc, uppcb, HSPCB and other spcbs), this guide explains your obligations, your options and the time limits that matter. Legals365 is the legal platform of Advocate B.K. Singh and associates, who appear before pollution control boards, the NGT and the courts.

In short. A state pollution control board notice is a formal communication from DPCC, UPPCB, HSPCB or another board alleging a breach of the Water Act, Air Act or Environment (Protection) Act, or of your consent conditions. Reply in writing within the time given, with documents, and ask for a personal hearing. Orders that follow can be appealed to the appellate authority and then the NGT.

Every state has a pollution control board, and Delhi has the Delhi Pollution Control Committee, which does the same job. These boards grant consent to establish and consent to operate (often called a pollution NOC), inspect units, take samples, and issue notices when they think something is wrong. A notice can be routine, such as a reminder that consent is about to expire, or serious, such as a proposed direction to close the unit and cut its electricity and water.

The notice is the cheapest stage at which to solve the problem. A clear reply with documents, a corrective step taken and recorded, and a well-prepared hearing can end the matter in the board's own office. A missed deadline or a one-line reply often leads to a closure direction, an environmental compensation demand or a prosecution. This page explains the kinds of notices boards issue, what the law requires them to do first, how to reply, how the position differs for factories, hospitals, builders, hotels and other units, and where to go if the board passes an order against you.

Law

Water (Prevention and Control of Pollution) Act 1974 (sections 21, 23, 25, 26, 28, 33A); Air (Prevention and Control of Pollution) Act 1981 (sections 21, 24, 26, 31, 31A); Environment (Protection) Act 1986 (section 5) and Environment (Protection) Rules 1986; waste management rules; Jan Vishwas (Amendment of Provisions) Act 2023 and Water Amendment Act 2024 on penalties.

Forum

The state board or DPCC itself, through its regional office and hearing committee. Appeals against consent orders go to the state appellate authority; appeals against directions and appellate orders go to the National Green Tribunal under section 16 of the NGT Act.

Time limit

The reply period stated in the notice, often 7 to 15 days, and at least 15 days for objections to a proposed direction under the EP Rules except in urgent cases. Appeal to the appellate authority within 30 days; NGT appeal within 30 days of communication, plus up to 60 days.

Documents

The notice and envelope or email, consent orders, inspection report and sample results if supplied, monitoring data, laboratory reports, waste records and returns, photographs and invoices for corrective works, and a board resolution or authority letter for the person replying.

What a pollution control board notice is

A pollution control board notice is the board telling you, in writing, that it believes you have broken an environmental law or a condition of your consent, and asking you to explain or correct it. It may be called a show cause notice, a notice of proposed directions, a deficiency letter, an inspection report with observations, or simply a letter. What matters is not the label but what the board proposes to do next.

Boards act under three main laws. The Water Act and the Air Act require most industries and many commercial establishments to hold consent and to meet discharge and emission standards. The Environment (Protection) Act and the rules under it cover hazardous waste, bio-medical waste, plastic waste, e-waste, construction and demolition waste, noise and DG sets, among others. The power to issue binding directions under section 5 of the EP Act has been delegated to board chairpersons, so a single notice can rely on all three laws at once.

A notice does not mean you have been found guilty of anything. It means the board has formed a view and is required, in most cases, to hear you before it acts. The reply is your chance to correct that view.

Which board, and who else may be involved

In Delhi the authority is the Delhi Pollution Control Committee (DPCC). In Uttar Pradesh it is the UP Pollution Control Board (UPPCB), working through regional offices such as Ghaziabad and Noida. In Haryana it is the Haryana State Pollution Control Board (HSPCB), with regional offices in places such as Faridabad and Gurugram. Telangana, Maharashtra, Gujarat, Karnataka, Tamil Nadu, West Bengal, Odisha, Rajasthan and other states each have their own board with similar powers and their own online consent systems.

The Central Pollution Control Board (CPCB) can issue directions to state boards and, under the EP Act, to units directly. In the National Capital Region, the Commission for Air Quality Management (CAQM) issues directions on air pollution, including restrictions under the Graded Response Action Plan, and state boards and DPCC enforce them. A notice can also follow an NGT order directing boards to act against a class of units, such as unauthorised units in residential areas or units without online monitoring.

Knowing who is really behind the notice matters. A notice issued to comply with an NGT or CAQM direction leaves the regional officer little room, and the reply should show compliance with that direction specifically. A notice that arises from a routine inspection gives more room to explain.

The provisions boards rely on

Common types of notice and what they usually mean

Read the notice before you reply

Start with three questions. Which provision is the board relying on? What exactly is alleged, with dates? What does the board propose to do, and by when must you respond? A notice under section 33A or section 31A proposing closure needs a different reply from a letter asking you to install a flow meter.

Check the details that are easy to miss. Is the notice addressed to the right entity and the right premises? Does it refer to your consent number, or to another unit? Is it based on an inspection you were told about, or one you never knew happened? Was a sample taken, and was it taken in your presence? If the notice refers to documents you have not received, such as an inspection report or analysis result, ask for them in writing at once and say that your reply will be completed when they arrive. Do not let that request stop you from filing a reply within time.

When a board notice reaches Advocate B.K. Singh, the first thing he checks is the date of receipt against the time given, and the second is whether the board has disclosed the material it relies on. Many notices can be answered fully only after the inspection report and sample result are obtained, and asking for them early is what makes the later hearing fair.

Inspections and sampling: where notices are often weak

A large share of serious notices rest on a sample that failed the prescribed standard. The Water Act and Air Act lay down how samples must be taken: the occupier is to be told, the sample collected in the occupier's presence, divided and sealed, and one part made available. Where this procedure was not followed, the result is open to challenge, and the Water Act expressly makes such a result inadmissible in legal proceedings.

Look at the sample record. Who signed it from your side, and was that person authorised? Was the sample taken from the final outlet or from an intermediate point? Was the plant running normally at the time, or was it under maintenance? Was the analysis done by a laboratory recognised for that purpose? If your own online monitoring or a third-party report on the same day shows a different result, put it forward.

Be careful not to rely only on procedure. A board that loses on sampling may simply come back, inspect again and take a proper sample. If the plant has a real problem, the stronger reply combines the procedural objection with proof that the problem has been fixed. For inspections that turn into seizure or sealing, see our page on pollution board inspections, raids and seizure.

How to reply to a pollution control board notice

The steps below apply to most notices, from a deficiency letter to a proposed closure.

1. Log the dates

   Note when the notice was received and the last date for reply. Keep the envelope, email header or portal screenshot. If the time is too short to collect documents, ask for an extension in writing before it expires, but prepare to reply anyway.

2. Ask for the material

   Request copies of the inspection report, photographs, sample record and analysis report the notice relies on. Ask for your counterpart sample if one was taken.

3. Fix what can be fixed

   If the allegation is right, start corrective work immediately: repair the ETP, install the meter, renew the consent application, clear the waste. Keep invoices, photographs and dated records. Boards respond to proof of action.

4. Draft the reply

   Answer each allegation in the order the notice raises it. Attach documents for every factual statement. Raise procedural objections clearly but briefly. State what you have done and what you will do, with dates.

5. Ask for a personal hearing

   Request a hearing before any order is passed. Attend with the person who knows the plant and with the documents. Hand over a short written note at the hearing.

6. Follow up

   After the hearing, file any documents the board asked for, and ask for a re-inspection once corrective work is complete. Keep a record of every submission.

The reply should be signed by an authorised person, with a board resolution or authority letter attached for a company or LLP. A reply signed by someone the board does not recognise can be ignored.

The personal hearing

Most boards give a personal hearing before passing a serious order, either before the regional officer, a hearing committee or the member secretary. The hearing is short. The officer has your file and wants to know three things: is the violation real, has it been corrected, and can the unit be trusted to stay compliant.

Bring the plant manager or environment officer, not just the lawyer. Carry originals and a set of copies, a one-page summary of the reply, and photographs printed with dates. If you are proposing a timeline for corrective work, make it realistic. A missed promise at this stage is remembered at the next inspection.

Ask that the hearing be recorded in the order sheet or minutes, and that your written note be placed on file. If the order that follows ignores what was said, that omission is a ground of appeal.

Pollution NOC: consent notices and categories

Most people call it a pollution NOC, but the law calls it consent: consent to establish before building a unit, and consent to operate before starting production. Industries are classified by CPCB guidelines into red, orange, green and white categories according to their pollution potential, and the validity of consent and the frequency of inspection depend on the category. White category units are generally exempt from consent, and recent central notifications have streamlined consent for some activities. Check the current list and your state's rules, because categories and validity periods are revised from time to time.

Notices about consent usually allege one of four things: the unit is running without consent, consent has expired, the unit has expanded or changed its product beyond what the consent allows, or a consent condition is being breached. The first two are the easiest to fix and the most dangerous to ignore, because operating without consent is a clear ground for closure. Expansion cases need care, because the expansion may also need an environmental clearance under the EIA Notification.

Applications are made through each board's online consent management system or the state single window. A unit that applied in time and is waiting for the board's decision should say so in its reply, with the application number and proof of fee. Our page on consent to establish and consent to operate covers applications, renewals and transfers.

Environmental compensation and penalties

Many notices now include, or are followed by, a demand for environmental compensation. This is not a fine but an amount meant to pay for the damage caused, usually calculated on a CPCB formula using factors such as the category of the unit, its size and the number of days of violation. In 2025 the Supreme Court confirmed that boards can demand restitutionary or compensatory damages under their directions powers, but stressed fair procedure and a framework laid down in advance.

So a compensation demand can be challenged. The common grounds are that the unit was not heard before the figure was fixed, that the period of violation is wrong (for example, counted from the date of an old consent rather than the date of the actual breach), that the formula has been applied to the wrong category, or that the violation was corrected earlier than the board assumed. Our page on environmental compensation demands goes through these in detail.

Separately, monetary penalties under the amended EP Act, Air Act and Water Act are decided by an adjudicating officer after a notice and inquiry. The law lists factors for fixing the amount, such as the harm caused, any gain made, and whether the violation is repeated. A reply to a penalty notice should address those factors directly.

Closure directions and disconnection of services

The most serious outcome of a notice is a direction to close the unit and to stop electricity and water supply. Boards can do this under section 33A of the Water Act, section 31A of the Air Act and section 5 of the EP Act. In ordinary cases a proposed direction must be preceded by notice and an opportunity to object. In cases of grave and immediate harm the board may act first, but it must record why.

If a closure direction has been issued, you have two tracks. One is compliance: correct the violations, report to the board, and apply for revocation of the closure, usually after a re-inspection and often with a bank guarantee or undertaking. The other is challenge: appeal to the NGT under section 16 and ask for a stay. Many units run both at once. The detail is on our page about closure notices and closure orders.

Do not reconnect electricity, break a seal or restart production without a written revocation or a court order. That converts a regulatory problem into a criminal one.

How the position differs by type of unit and by state

For a factory, notices usually concern effluent quality, stack emissions, online monitoring, hazardous waste records or expansion without consent. The reply relies on monitoring data, laboratory reports, manifests and consent conditions. For a hospital or clinic, the focus is bio-medical waste authorisation, segregation and the agreement with the common treatment facility. For a hotel, restaurant, banquet hall or mall, DG sets, kitchen exhaust, sewage and noise are common grounds.

For a builder or a group housing society, notices often relate to construction dust, construction and demolition waste, sewage treatment plants and groundwater use. Societies sometimes inherit violations from the builder, such as an STP that never worked, and the reply should place the history on record. For a warehouse or small unit in a residential or non-conforming area, the board may say the activity is not permitted there at all, which raises zoning questions beyond pollution law.

The board's approach also varies by place. Delhi and the NCR districts work under constant pressure from CAQM directions and NGT orders, so seasonal restrictions on DG sets, construction and certain fuels can lead to quick action. Industrial clusters that the CPCB identified as critically polluted see more frequent inspections. In other states the regional office has more discretion, and a prompt, complete reply often closes the matter at that level.

Documents to gather before replying

Mistakes that make a notice worse

• Ignoring it. Boards often treat silence as admission, and the next communication may be a closure direction.
• A one-line denial. Saying the unit is fully compliant, without documents, carries no weight.
• Arguing only procedure. Even a strong objection to sampling helps little if the plant is still polluting; fix the problem and say so.
• Promising dates you cannot meet. Missed undertakings are cited against the unit in later orders and before the NGT.
• Letting consent lapse. Operating on expired consent is one of the clearest grounds for closure and compensation.
• Wrong signatory. A reply from someone without authority can be disregarded.
• Restarting after closure without written permission. Breaking a seal or reconnecting power exposes directors to prosecution.
• Missing the appeal deadline. The NGT cannot extend time beyond the statutory 60 days.

If the board passes an order: appeal and other remedies

Orders refusing, cancelling or attaching conditions to consent can be appealed to the appellate authority constituted by the state government under section 28 of the Water Act and section 31 of the Air Act, within 30 days. Orders of the appellate authority, and directions under section 33A of the Water Act and section 31A of the Air Act, can be appealed to the National Green Tribunal under section 16 of the NGT Act within 30 days of communication, with a further 60 days possible for sufficient cause.

Directions under section 5 of the EP Act and penalty orders under the amended laws have their own routes, which may be an application to the NGT or an appeal provided in the amended provisions. Check the order itself, which often states the remedy. A writ petition before the High Court is used where the order is wholly without jurisdiction or in breach of natural justice, though High Courts often send environmental matters to the NGT. Our page on filing and defending a case in the National Green Tribunal explains that stage.

Appeals and compliance are not alternatives. The NGT is more willing to stay a closure for a unit that has already started fixing the problem and can show it.

What to do this week if you have received a board notice

• Write down the date of receipt and the last date for reply.
• Identify the provision relied on and what the board proposes to do.
• Send a written request for the inspection report, sample record and analysis report.
• Pull out your consents, authorisations, monitoring data and laboratory reports.
• Start corrective work on any genuine defect and keep dated proof.
• Draft a point-by-point reply and ask for a personal hearing.
• Get a board resolution or authority letter for the signatory.
• Check related pages: show cause notice replies, air emissions, OCEMS and DG sets, effluent discharge and ETP compliance and hazardous waste authorisation.

The next step

A board notice is a deadline and an opportunity at the same time. Treated seriously, it is usually resolved in the board's own office. Treated casually, it becomes a closure order, a compensation demand and an NGT appeal. Units that also face construction dust and C&D waste notices or EPR penalty notices should handle them together, because boards often look at the whole compliance record.

If you want the papers checked before you act, the team of Advocate B.K. Singh at Legals365 can review them and tell you the next step: talk to a lawyer.

Dealing with the CPCB

The Central Pollution Control Board is the national pollution regulator. It was constituted under the Water (Prevention and Control of Pollution) Act 1974 and works under the Air Act 1981 as well, with powers delegated under the Environment (Protection) Act 1986. It sets standards, coordinates and guides the state pollution control boards, resolves disputes between them, and runs the national monitoring networks for air and water quality. For day-to-day consents an industry deals with its state board or, in Delhi, the Delhi Pollution Control Committee, but the CPCB decides much of what those consents demand.

Three of its functions matter most to businesses. First, it classifies industries into red, orange, green and white categories, which decides how strict the consent regime is and how often a unit is inspected. Second, it can issue directions, including closure or stopping power and water supply, under section 5 of the Environment (Protection) Act, and it can direct state boards under section 18 of the Water and Air Acts. Third, it runs the centralised portals for extended producer responsibility under the rules on plastic packaging, e-waste, batteries, tyres and used oil, where producers, importers and brand owners register, file returns and buy or generate EPR certificates.

EPR enforcement has become a frequent source of notices. A brand owner that has not registered, has under-reported the quantity placed on the market, or has not met its recycling targets can face environmental compensation calculated under CPCB guidelines and suspension of registration. Recyclers and processors face scrutiny of the certificates they issue, and the CPCB has cancelled registrations where it found fake or inflated claims. Keeping sales data, invoices and recycler certificates consistent is the main defence.

The CPCB also appears often as a party or technical adviser in litigation. The NGT regularly appoints joint committees with the CPCB and the state board to inspect sites and report, and in Delhi NCR the CPCB works alongside the Commission for Air Quality Management on dust, industrial fuel and vehicle norms. Its flying squads inspect industries in the NCR and report violations. Industries in the seventeen highly polluting categories must connect online monitoring systems to CPCB servers, and data from those systems frequently forms the basis of a notice.

A notice or direction from the CPCB should be answered in writing within the time given, with data, photographs and a compliance plan. Directions and compensation orders can be challenged before the NGT or, where the complaint is about lack of hearing or jurisdiction, before the High Court in a writ. Ignoring the notice and waiting for the state board to sort it out rarely works.

Frequently asked questions

What should I do after receiving a pollution control board notice?

Note the reply deadline, ask the board for the inspection report and sample results, and start fixing any genuine defect. Then file a point-by-point written reply with documents and ask for a personal hearing. Do not ignore the notice.

How many days do I get to reply to a DPCC or UPPCB notice?

The notice states the period, often 7 to 15 days. For proposed directions under the EP Rules, at least 15 days is normally required unless the board records that the matter is urgent. If you need more time, ask in writing before the deadline expires.

What is a pollution NOC?

It is the common name for consent to establish and consent to operate under the Water Act and Air Act, granted by the state board or DPCC. Most industries and many commercial units need it. White category units are generally exempt; check the current list.

Can the pollution board close my factory without hearing me?

Ordinarily the board must give notice and an opportunity to object before issuing closure directions. In cases of grave and immediate harm it can act first, but it must record its reasons. A closure without hearing can be challenged before the NGT.

Can I challenge a failed sample report?

Yes, if the sampling procedure in the Water Act or Air Act was not followed, for example if the sample was not taken in your presence or not split and sealed. Combine that objection with proof that the plant meets the standards.

Where do I appeal against a pollution board order?

Consent orders go first to the state appellate authority within 30 days. Directions under section 33A of the Water Act or section 31A of the Air Act, and appellate authority orders, go to the NGT under section 16 within 30 days, extendable by up to 60 days.

Is environmental compensation the same as a fine?

No. It is meant to pay for environmental damage and is calculated on a formula or on evidence of harm. The Supreme Court confirmed in 2025 that boards can demand it, subject to fair procedure, so the basis and amount can be challenged.

Are pollution offences still criminal?

Many offences under the EP Act and Air Act, and under the Water Act where the 2024 amendment applies, were replaced by monetary penalties decided by an adjudicating officer. Some serious breaches and non-compliance with directions can still lead to prosecution. Check the current provisions.

Can I restart my unit after a closure order if I fix the problem?

Only after the board revokes the closure in writing, or a court or the NGT orders otherwise. Apply for revocation with proof of compliance and ask for re-inspection. Restarting without permission can lead to prosecution.

Does a housing society get pollution board notices?

Yes, commonly about sewage treatment plants, DG sets, groundwater use and solid waste. If the problem was left by the builder, the reply should record that history and the steps the society is now taking.

What is the role of CPCB if the notice is from a state board?

CPCB sets standards and can issue directions to state boards and, under the EP Act, to units directly. Most notices are issued by the state board or DPCC, sometimes to comply with CPCB, CAQM or NGT directions.

Who should sign the reply to a pollution board notice?

The occupier or an authorised person. For a company or LLP, attach a board resolution or authority letter. A reply signed by someone without authority may be disregarded.

Is the CPCB or the state board responsible for my factory's consent?

The state pollution control board, or the DPCC in Delhi, issues consent to establish and operate. The CPCB sets the standards and categories, runs the EPR portals and can issue directions directly, especially to highly polluting units or after its own inspections.

What is EPR registration with the CPCB?

Producers, importers and brand owners of plastic packaging, electronic goods, batteries and certain other products must register on the CPCB's EPR portals and meet yearly collection or recycling targets. Failure to register or to meet targets can lead to environmental compensation and suspension of registration.
