When Can a Pollution Control Board Order the Closure of an Industry?

A show-cause notice from a State Pollution Control Board proposing closure of a factory is among the most consequential letters an Indian manufacturer can receive. Section 31A of the Air (Prevention and Control of Pollution) Act, 1981 and Section 33A of the Water (Prevention and Control of Pollution) Act, 1974 empower boards, including the Andhra Pradesh Pollution Control Board (APPCB), to direct that an industry be closed and its electricity and water supply stopped. The power is broad, but it is not unfettered: the Supreme Court and the National Green Tribunal have insisted on a reasoned show-cause notice, a genuine opportunity of hearing, and evidence that ties the alleged pollution to the specific facility. How those safeguards operate, and where an aggrieved industry can appeal, often determines whether a closure direction survives.

A Deliberately Broad Power

Section 31A was inserted into the Air Act by the Air (Prevention and Control of Pollution) Amendment Act, 1987, with effect from 1 April 1988. Its operative language is sweeping:

"Notwithstanding anything contained in any other law, but subject to the provisions of this Act, and to any directions that the Central Government may give in this behalf, a Board may, in the exercise of its powers and performance of its functions under this Act, issue any directions in writing to any person, officer or authority, and such person, officer or authority shall be bound to comply with such directions. Explanation.—For the avoidance of doubts, it is hereby declared that the power to issue directions under this section includes the power to direct (a) the closure, prohibition or regulation of any industry, operation or process; or (b) the stoppage or regulation of supply of electricity, water or any other service."

Section 33A of the Water Act is in identical terms, conferring the equivalent power on state boards for water pollution control (the Air Act text is available here). Neither section prescribes preconditions for invoking the closure power. The statutory discretion operates "notwithstanding anything contained in any other law", and is textually limited only by the provisions of the parent Acts and by directions of the Central Government. The third limit, constitutional due process and natural justice, is implied rather than written, and it is where most closure battles are fought.

The Show-Cause Notice Is Not Optional

Although Sections 31A and 33A do not expressly mandate a show-cause notice, the Supreme Court and the National Green Tribunal have established that procedural fairness is constitutionally required before the power is exercised. The NGT's Central Zone Bench in M/s Surjeet Hyundai (Auto Pvt. Ltd.) v. Member Secretary, Madhya Pradesh Pollution Control Board, Appeal Nos. 09 and 10 of 2025 (decided 8 January 2026), anchored the requirement partly in Section 20 of the NGT Act, which obliges the Tribunal to apply the principles of sustainable development, the precautionary principle and the polluter pays principle, and held:

"…the showcause notice explaining the reasons must be given to the defaulter unit and the unit must be given an opportunity of hearing on the matter."

Before ordering closure or imposing environmental compensation, therefore, a board must do three things:

1. issue a show-cause notice explaining the specific violations and the reasons for the proposed action;
2. give the industry reasonable time to respond; and
3. grant an opportunity of hearing at which the industry can present its case.

Fairness in Substance, Not Form

Natural justice in this field is contextual, not mechanical. In Chairman, Board of Mining Examination v. Ramjee, AIR 1977 SC 965, the Supreme Court cautioned:

"Natural justice is not an unruly horse, no lurking landmine, nor a judicial cure-all. If fairness is shown by the decision-maker to the man proceeded against, the form, features and the fundamentals of such essential processual propriety being conditioned by the facts and circumstances of each situation, no breach of natural justice can be complained of."

In State Bank of Patiala v. S.K. Sharma, (1996) 3 SCC 364, the Court added the critical qualification: procedural violations do not automatically void an order unless they prejudiced the affected party. The test is whether the industry received a fair hearing in all the circumstances. Where the unit was given specific notice of the violations, a reasonable opportunity to respond in writing, a hearing before a committee (even if not a full oral hearing), and genuine consideration of its submissions, the absence of strict procedural formality may not vitiate the order if no prejudice resulted. The law also distinguishes substantive from procedural violations: substantive requirements, such as the obligation to hold an authorisation at all, demand strict compliance, while procedural lapses are assessed for the prejudice they caused.

The practical battleground is specificity. A notice that identifies the discharge points, dates and contaminants relied on can be answered; a notice alleging only "wastewater discharge" or "zone-wide pollution" in general terms may itself be procedurally unfair, because it denies the unit any meaningful basis for response.

Whose Pollution? Attribution in Shared Industrial Zones

Where a unit, say a beverage manufacturer, operates inside a multi-industry estate, a recurring question is whether the board must prove facility-specific pollution or may proceed on the footing that every occupant shares responsibility for the zone's environmental condition.

The statutory framework points to individual attribution. Sections 25 and 26 of the Water Act and Section 21 of the Air Act prohibit discharge and operation without a Consent to Operate (CTO); violations of CTO conditions, such as unauthorised wastewater discharge, odour emissions or hazardous waste mismanagement, are attributable to the specific industry found operating in violation, not to the zone as a whole. In Surjeet Hyundai, the Tribunal tested the particular facility against its own consent conditions (untreated water discharge from a car-wash service station) and upheld environmental compensation against that facility, while making clear that industries cannot evade responsibility simply by pointing to zone-wide pollution.

For an individual closure direction to stand, the board should be able to produce:

• inspection reports specifically identifying the unit's own discharge or emission points;
• effluent or air quality sampling data from those points;
• laboratory analysis showing breach of CTO limits;
• temporal correlation, such as discharge occurring during operational hours and ceasing during shutdown; and
• evidence that pollution control equipment (an effluent treatment plant or air scrubber) was not operated or had malfunctioned.

If the notice rests on zone-wide contamination data without attributing specific volumes or sources to the unit, the evidentiary standard for individual closure is not met. Closure orders covering multiple industries remain possible, but they must be based on separate facility-wise inspection reports, must specify which conditions each industry violated, and cannot bundle unrelated units together absent evidence of common causation, such as the failure of a shared effluent treatment system.

A caveat is due: no reported decision squarely addressing attribution standards for industrial zones in Andhra Pradesh appears to have been located. The principles above derive from Madhya Pradesh and Tamil Nadu matters and are persuasive, rather than binding, before the APPCB.

Environmental Compensation: Restitution, Not a Fine

Closure notices are frequently paired with a demand for environmental compensation. The two are legally distinct. Compensation is a restitutionary measure grounded in the polluter pays principle recognised in Indian Council for Enviro-Legal Action v. Union of India, (1996) 3 SCC 212:

"According to the Polluter Pays principle the responsibility for repairing the damage is that of the offending industry… the said powers will include giving directions for the removal of sludge, for undertaking remedial measures and also the power to impose the cost of remedial measures on the offending industry…"

State boards impose environmental compensation as a direction for restitution of environmental damage, separately from the penal provisions such as Section 37 of the Air Act. The consequence matters: even if a closure order is stayed or set aside, the board may still pursue environmental compensation as a separate remedy based on documented violations of consent conditions.

The CPCB Formula

The Central Pollution Control Board has issued a compensation methodology adopted by state boards, including the APPCB (see, for instance, the Haryana State Pollution Control Board's order of 22 December 2021 adopting the CPCB guidelines, and the CPCB report filed in NGT Appeal No. 2 of 2024). For discharges violating consent conditions, particularly water pollution, the formula is:

Environmental Compensation = PI × N × R × S × LF

Worked through, a Red-category food and beverage unit (PI 80) in violation for 60 days at medium scale (S 1.0) in a standard municipal location (LF 1.0) faces 80 × 60 × ₹250 × 1.0 × 1.0 = ₹12,00,000. Non-payment escalates steeply under the CPCB guidelines:

• within 15 days of the due date: the original amount plus 12% interest per annum;
• after 15 days and up to 3 months: twice the original amount plus 12% interest;
• after 3 months and up to 6 months: four times the original amount plus 12% interest;
• after 6 months: closure of the facility and court action.

Two hedges apply. The Red/Orange/Green categorisation of a packaged drinking water or soft-drink unit depends on its actual process: reverse osmosis, UV treatment, chemical pH adjustment or chlorination can change the classification and hence the Pollution Index. And a state board may apply modified guidelines for particular sectors or zones, so the standard CPCB arithmetic is a starting point rather than a fixed liability.

Consent Conditions, Waste Classification and the APEMCL Question

A CTO, issued after the Consent to Establish stage, specifies the operating conditions whose breach triggers all of the above. For food and beverage manufacturers, typical conditions cover wastewater discharge standards (limits for BOD, COD and suspended solids, pH and temperature ranges, effluent treatment plant performance, and no untreated discharge to water bodies), air emission and odour limits aligned to national ambient air quality standards, and hazardous waste management through authorised facilities with manifest documentation. Violation takes familiar forms: discharging untreated or partially treated effluent, continuing operations with a malfunctioning treatment plant, discharging to unauthorised locations such as groundwater or open drains, exceeding odour limits, routing hazardous waste through unauthorised vendors, or failing to maintain monitoring records.

Waste classification matters to the defence. Food and beverage manufacturing typically generates non-hazardous streams: organic sludge from wastewater treatment, processing residues and packaging waste. Potentially hazardous streams include spent activated carbon, cleaning chemicals and solvents, laboratory waste and heavy-metal-bearing filters. Under the Hazardous and Other Wastes (Management and Transboundary Movement) Rules, 2016, hazardous waste is any waste which "by reason of characteristics such as physical, chemical, biological, reactive, toxic, flammable, explosive or corrosive, causes danger or is likely to cause danger to health or environment", including wastes specified in Schedule I (the Rules are available here). Packaged drinking water and soft drinks producers typically do not generate Schedule I wastes unless their processes involve chemical treatment. But the point has a sharp edge: unauthorised wastewater discharge violates Sections 25 and 26 of the Water Act and the CTO regardless of hazardous waste classification, and by itself attracts the closure power under Section 33A.

In Andhra Pradesh a further layer applies. A Treatment, Storage and Disposal Facility (TSDF) is a common facility, authorised under Rule 6 of the 2016 Rules, that treats and disposes of hazardous waste at licensed premises. The Andhra Pradesh Environment Management Corporation Limited (APEMCL), established by the state government by G.O. Ms. No. 39 dated 5 December 2019, is not itself a TSDF but a facilitator that routes hazardous waste from generators to authorised TSDFs. Recent APPCB consent amendments mandate that "the industry shall dispose the Hazardous and Other Wastes through M/s. Andhra Pradesh Environment Management Corporation Limited (APEMCL) as per the Disposal Option given in the HW Authorization." An "authorised vendor", typically a transporter holding board registration, is not the same thing; routing hazardous waste through such a vendor instead of the TSDF/APEMCL chain is itself a consent violation attracting closure authority.

A Forked Appellate Road

The remedies against a closure direction depend, awkwardly, on which statute it invokes.

Directions under Section 31A of the Air Act are not appealable to the NGT or any appellate authority; the statutory scheme provides no appeal mechanism. Such orders remain open to judicial review under Article 226 before the High Court, but only on grounds of violation of natural justice, absence of necessary evidence, or arbitrary and irrational decision-making. The Supreme Court's decision in Tamil Nadu Pollution Control Board v. Sterlite Industries (India) Ltd., (2019) 19 SCC 479, is the reference point on the non-appealability of Section 31A directions and the scope of the closure power.

Directions under Section 33A of the Water Act are appealable to the NGT under Section 16 of the NGT Act, 2010 read with Section 33B(c) of the Water Act. On such an appeal the Tribunal can examine the merits: the evidentiary basis of the findings and whether the direction was proportionate to the violation.

A combined order under both provisions therefore splits the forum. The Section 33A portion goes to the NGT; the Section 31A portion can only be tested in a writ petition; and a composite order risks inconsistent review of the same facts. Strategically, the NGT offers merits review and receptivity to technical evidence on facility-specific versus zone-wide pollution, while the writ jurisdiction is confined to legality. Identifying the statutory composition of the order is the first step in choosing the remedy.

Practical Takeaways

• Obtain a certified copy of the complete show-cause notice with all annexures: inspection reports, laboratory results with dates, parameters and sampling locations, photographs, and the compliance history relied on.
• Cross-reference every allegation against the specific clauses of the current (and any renewed) Consent to Operate, and note any ambiguities or condition changes.
• Test attribution: ask which monitored discharge points belong to the unit; where the notice relies on zone-wide data, demand an itemised breakdown, and where a common effluent facility has failed, argue shared responsibility rather than individual closure.
• Build the natural-justice record: log every communication and hearing, and document remedial action (treatment plant repair, process modification) with independent certification.
• Pin down whether the allegation is untreated wastewater discharge, hazardous waste mismanagement, or both; the defences differ, and only genuinely Schedule I streams attract the TSDF/APEMCL routing requirements.
• Budget for environmental compensation using the CPCB formula even while contesting closure, and consider proposing a remediation plan and timeline as an alternative to a flat demand.
• Choose the forum by the order's composition: Section 33A alone, appeal to the NGT; a combined order, an NGT appeal alongside a High Court writ; Section 31A alone, the writ is the only route.
• Comply in parallel: repairing treatment systems and switching to authorised waste routing while the notice is contested supports a plea for suspension of closure pending final hearing.
