The Environment Protection Act 1986 is the statute under which almost every operative environmental rule in India is made, and it is also a statute that contains almost none of those rules itself. It runs to twenty-six sections. It fixes no emission limit for any factory, prescribes no effluent standard for any river, names no substance whose discharge it forbids in any quantity, and sets no procedure by which a factory, mine, port or housing project must obtain permission to exist. Every one of those things is done elsewhere, in notifications and rules issued by the Central Government in the Gazette of India under the powers this Act confers. A reader who masters the twenty-six sections has therefore mastered the skeleton of Indian environmental law and nearly nothing of its flesh. The flesh is delegated legislation, and it can be rewritten by the executive without a bill, without a debate and without a vote.

That arrangement is not an accident of drafting, and it is not a loophole that later governments discovered in an innocent text. It is the design. Parliament in 1986 wanted a law that could reach any environmental problem, including problems nobody had yet named, and it chose reach over specification: a definition of the environment wide enough to cover water, air, land and the relationships among them, a power in the Central Government to take all such measures as it deems necessary or expedient, and a set of prohibitions that bite only when a standard has been prescribed somewhere else. The consequence, forty years on, is that the most consequential environmental decisions in India, the impact assessment regime that decides which projects may proceed, the coastal rules that decide what may be built within five hundred metres of the sea, and every waste stream rule from hospital refuse to discarded phones, were made and repeatedly remade by notification. This article explains the Act section by section, maps the instruments that carry its substance, states the enforcement and penalty system as the Jan Vishwas amendments rebuilt it, and then takes up the argument the structure forces: whether environmental law by gazette is a sensible accommodation with technical government, or a standing transfer of the legislative function that no Parliament should have made.

Why Parliament wrote the Environment Protection Act 1986 as an umbrella

The Act begins by declaring its own origin. Its long title records that it is an Act to provide for the protection and improvement of the environment and for matters connected therewith, and its preamble explains that decisions were taken at the United Nations Conference on the Human Environment held at Stockholm in June 1972, in which India participated, calling upon states to take appropriate steps for the protection and improvement of the human environment, and that it was considered necessary to implement those decisions insofar as they relate to the protection and improvement of the environment and the prevention of hazards to human beings, other living creatures, plants and property. That preamble does constitutional work. Article 253 of the Constitution empowers Parliament to make any law for the whole or any part of India for implementing any treaty, agreement or convention with any other country, or any decision made at an international conference, association or other body, and it does so notwithstanding the ordinary distribution of legislative powers between the Union and the states. A statute enacted under Article 253 can therefore reach subjects that would otherwise sit in the state list, which is precisely what a general pollution statute needs to do. Water is principally a state subject. Land is a state subject. Public health is a state subject. An environmental code routed through the ordinary entries would have fragmented at every border, so Parliament routed this one through Stockholm.

The constitutional soil had been prepared a decade earlier. A committee appointed to review the legislative measures and administrative machinery for environmental protection, which reported in 1980, had recommended both a department of environment at the Centre and comprehensive central legislation; the Department of Environment was created in 1980 and raised to a full Ministry of Environment and Forests in 1985, so that when the Act arrived there existed, for the first time, a ministry to wield it. The need for a new instrument was equally plain, because the statute book the Ministry inherited was medium-bound and consent-bound. The Water (Prevention and Control of Pollution) Act, 1974 had created the central and state boards and a consent system for discharges into water; the Air (Prevention and Control of Pollution) Act, 1981 had extended the same boards to air; the Factories Act reached hazards inside the factory gate; and nothing reached land contamination, hazardous waste beyond the factory, noise, or a coastline. Bhopal fell precisely into the gaps between those statutes: a hazard created by storage and process, injuring through air, settling on land and water, generated by an industry the boards licensed for effluent and emission but whose catastrophic risk no consent had ever assessed.

The immediate spur was not Stockholm, which was fourteen years past, but Bhopal. The Constitution (Forty-second Amendment) Act, 1976 inserted Article 48A into the Directive Principles, providing that the State shall endeavour to protect and improve the environment and to safeguard the forests and wildlife of the country, and Article 51A(g) into the fundamental duties, making it the duty of every citizen to protect and improve the natural environment including forests, lakes, rivers and wildlife, and to have compassion for living creatures. Neither provision is enforceable by a court on its own. What they supplied was a text the courts could read with Article 21, and the Supreme Court did so: in Subhash Kumar v. State of Bihar, decided in 1991, the Court held that the right to life under Article 21 includes the right of enjoyment of pollution-free water and air for full enjoyment of life. The statute of 1986 thus sits between a constitutional commitment above it and a body of judge-made principle below it, and it is best understood as the machinery provision for both.

The immediate spur was not Stockholm, which was fourteen years past, but Bhopal. In the night of 2 and 3 December 1984, methyl isocyanate gas leaked from the pesticide plant of Union Carbide India Limited at Bhopal, killing thousands of people within days on the official counts, injuring several lakh more, and exposing the near-total absence of a legal regime for industrial disaster: no general duty of care codified for hazardous processes, no single authority answerable for the aftermath, and a compensation battle that had to be fought through a special statute, the Bhopal Gas Leak Disaster (Processing of Claims) Act, 1985, and litigation that reached a settlement in 1989 whose adequacy is argued about to this day. The disaster, and the legislative settlement that followed it, are the subject of the companion history of the Bhopal disaster and the environmental legislation it produced, and they are sketched here only because they explain the two features of the 1986 Act that puzzle first-time readers: its speed and its breadth. A legislature reacting to a catastrophe does not draft a code of standards, because a code takes years and the next accident will not resemble the last one. It drafts a power. It gives the executive authority over everything, trusts the executive to specify, and reserves for itself almost nothing except the framework. The Environment (Protection) Act, 1986 received the assent of the President on 23 May 1986 as Act 29 of 1986, and it was brought into force on 19 November 1986. Its twenty-six sections have never been substantially expanded. They have never needed to be.

When did the Environment Protection Act come into force?

The Environment (Protection) Act, 1986 is Act 29 of 1986. It received the assent of the President on 23 May 1986 and was brought into force on 19 November 1986, a date appointed by the Central Government by notification under Section 1(3). It extends to the whole of India.

That gap between assent and commencement, unremarkable in itself, contains the Act in miniature. Parliament finished its work in May. The operative law began when the executive notified it in November, and the executive has been finishing Parliament’s work under this statute, notification by notification, ever since. Even the territorial and subject reach of the Act is framed for maximum elasticity: Section 1 applies it to the whole of India, and the definitions that follow are drawn so that a pollutant, a hazardous substance and an environmental harm can be recognised wherever and in whatever medium they appear. The drafting choice Parliament made in 1986, to legislate the power and delegate the content, is the single fact from which everything else in Indian environmental law follows, and it is the fact the rest of this article keeps returning to.

A statute of twenty-six sections: the anatomy

The Act is organised into four chapters. Chapter I, comprising Sections 1 and 2, contains the title, extent and commencement, and the definitions. Chapter II, comprising Sections 3 to 6, contains the general powers of the Central Government: the omnibus power, the power to appoint officers, the power to give directions, and the power to make rules on standards and safeguards. Chapter III, comprising Sections 7 to 17, contains the prevention, control and abatement machinery: the prohibitions, the accident duty, the powers of entry, inspection and sampling, the laboratories and analysts, and, as enacted, the offences and penalties. Chapter IV, comprising Sections 18 to 26, contains the miscellaneous provisions: protection for action taken in good faith, the cognizance rule, the public servant provision, the bar of civil jurisdiction, the delegation power, the overriding effect clause, the rule-making power and the laying requirement. The Jan Vishwas amendments of 2023, which took effect for this Act on 1 April 2024, inserted Sections 14A and 14B, replaced Sections 15 to 17 with a new penalty code running from Section 15 to Section 15F, and inserted a new Chapter IIIA on the fund, accounts and audit, without altering the four-chapter skeleton a reader meets first.

Section 2 carries the definitions, and two of them do most of the work. Environment, under Section 2(a), includes water, air and land and the interrelationship which exists among and between water, air and land, and human beings, other living creatures, plants, micro-organisms and property. The definition is famous for what it refuses to do: it does not list ecosystems, species or resources as objects of protection in themselves, but instead defines the environment as a medium plus a web of relationships, which means anything that alters the medium or the relationships falls within the Act. An environmental pollutant, under Section 2(b), means any solid, liquid or gaseous substance present in such concentration as may be, or tend to be, injurious to the environment, and environmental pollution, under Section 2(c), means the presence of any environmental pollutant in the environment. The circularity is deliberate and functional. A substance is a pollutant not because Parliament has listed it but because of its concentration and its tendency to injure, so the Act never goes out of date as chemistry changes; what fixes the legal line in any concrete case is the standard prescribed under the rules, which is again the delegation design appearing inside the definitions themselves. A hazardous substance, under Section 2(d), means any substance or preparation which, by reason of its chemical or physico-chemical properties or handling, is liable to cause harm to human beings, other living creatures, plants, micro-organisms, property or the environment. An occupier, under Section 2(e), in relation to any factory or premises, means a person who has control over the affairs of the factory or the premises, and includes, in relation to any substance, the person in possession of the substance. Handling, under Section 2(f), in relation to any substance, means the manufacture, processing, treatment, package, storage, transportation, use, collection, destruction, conversion, offering for sale, transfer or the like of such substance.

Taken together, these definitions explain why the Act is called an umbrella, a description the first of the frequently asked questions below examines in full. One further definition, easily skipped, is the hinge on which the whole drafting technique swings: Section 2(g) provides that “prescribed” means prescribed by rules made under this Act. The word appears wherever the parent statute needs content it does not supply: the standards of Section 7 are the prescribed standards, the procedure and safeguards of Section 8 are the prescribed ones, the authorities to whom accidents are intimated under Section 9 are the prescribed authorities, the manner of giving notice under Section 19 is the prescribed manner. Each occurrence of “prescribed” in the Act is a small door opening out of the statute into the rule book, and counting them is a quick way to feel how little of the operative law Parliament kept. The Water Act, by contrast, states several of its standards and procedures in its own text and schedules, and the Air Act does the same for its areas and consents; the Act of 1986 is built, from its definitions outward, to be completed elsewhere. The Water Act of 1974 governs pollution of water. The Air Act of 1981 governs pollution of air. Each is tied to a medium, to a board structure and to a consent system. The Act of 1986 is tied to none of these limits: its definition of the environment spans all media and the relations among them, its powers are vested in the Central Government rather than in a specialist board, and its subject matter is whatever the Central Government identifies as an environmental problem. Noise became an environmental pollutant under this Act’s rule-making without any amendment to the Act. Groundwater extraction, which no Indian statute then regulated, was brought under control through an authority this Act made possible. Genetically engineered organisms, electronic waste, battery waste, construction debris and the plastic carry bag all entered Indian law through instruments under this Act, none of them through an amendment of it. The umbrella metaphor, often used loosely, is here a precise statement about legislative technique: one short parent statute, indefinitely many subordinate instruments, and no need to return to Parliament when a new problem needs a rule.

Section 3: the power to take all such measures

Section 3(1) is the heart of the Act, and it deserves to be read at the pace its drafters wrote it: subject to the provisions of this Act, the Central Government shall have the power to take all such measures as it deems necessary or expedient for the purpose of protecting and improving the quality of the environment and preventing, controlling and abating environmental pollution. Every word of qualification points inward to the Act itself, and the Act contains almost no qualifications to find. The test of a measure is that the Central Government deems it necessary or expedient for an environmental purpose. Section 3(2) then provides that, in particular and without prejudice to the generality of sub-section (1), such measures may include measures with respect to all or any of a list of matters, and the list repays attention because later instruments trace their authority to particular items in it. The list covers the co-ordination of actions by state governments, officers and other authorities under this Act or under any other law relatable to its objects; the planning and execution of a nationwide programme for the prevention, control and abatement of environmental pollution; the laying down of standards for the quality of the environment in its various aspects; the laying down of standards for emission or discharge of environmental pollutants from various sources, with an express proviso that different standards may be laid down for different sources having regard to the quality or composition of the emission or discharge; the restriction of areas in which industries, operations or processes shall not be carried out or shall be carried out subject to certain safeguards; the laying down of procedures and safeguards for the prevention of accidents which may cause environmental pollution and for remedial measures for such accidents; the laying down of procedures and safeguards for the handling of hazardous substances; the examination of manufacturing processes, materials and substances likely to cause environmental pollution; the carrying out and sponsoring of investigations and research; the inspection of premises, plant, equipment, machinery, processes, materials and substances, and the giving of directions to authorities, officers and persons; the establishment or recognition of environmental laboratories and institutes; the collection and dissemination of information about environmental pollution; the preparation of manuals, codes and guides; and such other matters as the Central Government deems necessary or expedient for securing the effective implementation of the Act.

Two features of that list matter more than any single item. The first is that it is expressly non-exhaustive, so it illustrates the power rather than confining it; a measure that fits none of the fourteen heads can still rest on sub-section (1) alone. The second is the fifth item, the power to restrict the areas in which industries and processes may be carried out, because it is the statutory root of the two most important instruments in Indian environmental law. The environmental impact assessment notification, which forbids listed projects from proceeding in any area without prior clearance, and the coastal regulation zone notification, which forbids classes of activity within a defined coastal strip, are both exercises of the Section 3 power to say where industry may and may not operate and on what safeguards. When the Supreme Court in 2026 upheld the one-time regularisation notification of 2017 against the charge that the Act permitted no such thing, it did so by reading this section at its full width, holding that Section 3 confers the widest amplitude of power on the Union to take necessary measures for protecting and improving the quality of the environment, and that a narrowly tailored statutory exception to the clearance regime could be engrafted by delegated legislation under it. The width of Section 3 is therefore not an academic observation. It is the ground on which the largest environmental cases of the past decade have been fought.

Section 3(3) completes the design. The Central Government may, if it considers it necessary or expedient for the purposes of the Act, by order published in the Official Gazette, constitute an authority or authorities by such name or names as may be specified in the order, for the purpose of exercising and performing such of the powers and functions of the Central Government under the Act, including the power to issue directions under Section 5, and for taking measures with respect to such of the matters in sub-section (2) as may be mentioned in the order, subject to the supervision and control of the Central Government. One sentence of the Act thus authorises the creation of regulators. India has used it to build regulators for the two problems the parent statute’s generation found hardest: groundwater and the air of the capital region.

What is an authority under Section 3(3) of the Act?

An authority under Section 3(3) is a body the Central Government creates by gazette order to exercise its powers under the Act, including the Section 5 power to issue binding directions, under the Central Government’s supervision and control. The Central Ground Water Authority of 1997 and the Environment Pollution (Prevention and Control) Authority of 1998 are the standing examples.

The Central Ground Water Authority is the cleaner illustration because a court ordered it into existence. Groundwater in India is extracted overwhelmingly through private wells on private land, under a common law rule tying the water to ownership of the surface, and no statute gave any regulator a general power over extraction. In M.C. Mehta v. Union of India, by an order of 10 December 1996 in the long-running environmental writ petition, the Supreme Court directed the Central Government to constitute the Central Ground Water Board as an authority under Section 3(3), armed with the Section 5 direction power and with the penal provisions of the Act, for the regulation and control of groundwater development and management. The Central Government complied by notification S.O. 38(E) dated 14 January 1997. The Authority built on that foundation a permit regime: no-objection certificates for groundwater extraction by industries, infrastructure projects and mining in assessed areas, conditions requiring rainwater harvesting and monitoring, and guidelines that have been revised by notification, the governing set being the guidelines notified on 24 September 2020. A resource used by tens of millions of people, which Parliament has never subjected to a comprehensive groundwater statute at the Centre, is regulated nationally because one sub-section of a 1986 Act lets the executive create the regulator by order.

The Environment Pollution (Prevention and Control) Authority, known by its initials EPCA, followed a year later, constituted by notification S.O. 93(E) dated 29 January 1998 under sub-sections (1) and (3) of Section 3, in pursuance of the Supreme Court’s directions in the same M.C. Mehta proceedings, and chaired from its constitution by Bhure Lal, a former Secretary to the Government of India. Its territory was the National Capital Region and its subject was air. For over two decades it was the body through which the Court’s continuing mandamus on Delhi’s air was channelled: the conversion of the capital’s bus fleet to compressed natural gas, the closure or relocation of polluting industry, and, late in its life, the Graded Response Action Plan, the schedule of escalating measures keyed to air quality levels that was prepared under its aegis and notified in January 2017, all ran through an authority that existed because a gazette order said so. When the Union decided that the capital’s air needed a permanent statutory commission with representation from the neighbouring states, it did not amend the Environment (Protection) Act; it legislated separately, first by ordinance in 2020, which dissolved EPCA and repealed its notification, and then by the Commission for Air Quality Management in National Capital Region and Adjoining Areas Act, 2021. The episode states the Section 3(3) bargain exactly. An authority created by notification can be built in a week and can govern for twenty-three years, and it can also be extinguished by the same instruments that created it, without Parliament ever having voted on its existence at either end.

The Loss of Ecology (Prevention and Payments of Compensation) Authority supplies the third model of a Section 3(3) body, the compensator. In the Vellore judgment discussed below, the Supreme Court directed the Central Government to constitute an authority under Section 3(3) to implement the polluter pays principle for the tannery belt of Tamil Nadu: to identify the loss of ecology, assess the compensation payable to individual victims and families, and recover it from the polluting tanneries. The Authority was constituted accordingly and spent years doing what no court could have done case by case, receiving claims from farmers across the affected districts, assessing damage to agricultural land and water, and awarding compensation charged to the industry collectively responsible. Between the Central Ground Water Authority the licensor, EPCA the supervisor and the Loss of Ecology Authority the compensator, the single sub-section has produced a regulator, a command post and a tribunal, none of them described in the Act beyond the bare power to constitute an authority by order. No other provision of Indian environmental law packs so much institutional variety into so few words, and none illustrates the delegation design more completely: Parliament did not create these bodies, decide their functions, or fix their tenure; it created the power to create them, and everything else was decided in the gazette.

The remaining plumbing of Chapter II is quickly stated. Section 4 empowers the Central Government to appoint officers with such designations as it thinks fit and to entrust them with such of its powers and functions as it may specify, subject to its supervision and control. Section 6, the first of the two rule-making provisions, empowers the Central Government to make rules in respect of all or any of the matters in Section 3(2), and then lists rule heads of its own: standards of quality of air, water or soil for various areas and purposes; the maximum allowable limits of concentration of various environmental pollutants, expressly including noise, for various areas; procedures and safeguards for the handling of hazardous substances; prohibitions and restrictions on the handling of hazardous substances in different areas; prohibitions and restrictions on the location of industries and the carrying on of processes and operations in different areas; and procedures and safeguards for the prevention of accidents and for remedial measures when accidents occur. Section 23, in Chapter IV, adds the general delegation power: the Central Government may by notification delegate its powers and functions under the Act to any officer, state government or other authority, with two exceptions that mark the limits Parliament did set, namely the power to constitute an authority under Section 3(3) and the power to make rules under Section 25, which the Centre keeps for itself. The pattern across these provisions is consistent. Everything operational can be pushed downward and outward by notification. The two things that cannot be delegated away are the creation of authorities and the making of rules, which are the two instruments by which the whole system reproduces itself.

The relationship between the Act’s two rule-making powers deserves a sentence of its own, because practitioners cite both and they are not interchangeable. Section 6 is the standards power: it authorises rules in respect of all or any of the matters in Section 3(2), and its own enumerated heads are the substance of environmental regulation, quality standards for air, water and soil, maximum allowable limits of concentration of pollutants including noise, procedures and safeguards for handling hazardous substances, prohibitions on handling them in specified areas, restrictions on the location of industries, and accident prevention and remediation procedures. Section 25 is the general power to make rules for carrying out the purposes of the Act, and its particular heads tie the rule book to the operative sections one by one: the standards in excess of which pollutants shall not be discharged under Section 7, the procedure for handling hazardous substances under Section 8, the authorities to whom accidents must be intimated under Section 9, the sampling, laboratory and analyst provisions, and the manner of the citizen’s notice under Section 19. A rule may accordingly draw on either or both powers, and the waste and subject rules habitually recite Sections 3, 6 and 25 together in their preambles, belt and braces drafting that reflects how completely the Act’s content was intended to live in its rules.

Section 5: directions that can close an industry

If Section 3 is the Act’s grant of power, Section 5 is its weapon. It provides that, notwithstanding anything contained in any other law but subject to the provisions of this Act, in the exercise of its powers and performance of its functions under the Act, the Central Government may issue directions in writing to any person, officer or authority, and such person, officer or authority shall be bound to comply with such directions. An Explanation then removes doubt about what directions may do: the power to issue directions includes the power to direct the closure, prohibition or regulation of any industry, operation or process, and the stoppage or regulation of the supply of electricity or water or any other service. The drafting is worth dwelling on. The direction runs not only against the polluter but against the utility: an order under Section 5 can lawfully instruct an electricity distribution company to disconnect a factory, which converts a regulatory decision into a physical fact within days, without the prosecution, trial and conviction that the penalty provisions require. No prior hearing is prescribed by the section, no threshold of harm is stated, and the class of persons who may be directed includes every officer and authority in the country. When lawyers describe the Environment (Protection) Act as the most powerful environmental statute on the Indian book, Section 5 is usually the provision they have in mind.

The power is exercised in practice through a chain of delegations and entrustments that the Act itself authorises. The Central Pollution Control Board, the statutory body under the Water Act, is routinely authorised to issue Section 5 directions, and does so in sector after sector: to industrial units in critically polluted clusters, to municipal bodies over sewage treatment, and to categories of industry directed to install continuous emission monitoring systems transmitting data to the Board in real time. The most sweeping single exercise of the power remains the moratorium of January 2010, when the Ministry of Environment and Forests, acting on the Central Board’s Comprehensive Environmental Pollution Index assessment of industrial clusters, suspended the consideration of new projects and expansions in forty-three critically polluted clusters until the state boards and the industries in each cluster produced and implemented remedial action plans, lifting the suspension cluster by cluster as plans were approved. No statute was amended to produce that moratorium, no regulation was debated; a direction-based regime under a 1986 power simply paused industrial expansion across a significant part of industrial India, and later relaxed it the same way. Section 3(3) authorities receive the Section 5 power as part of their constitution, which is how the Central Ground Water Authority directs district magistrates to seal borewells and how EPCA directed the measures that governed the capital’s air.

Parliament has attached exactly one procedural counterweight to Section 5, and it arrived twenty-four years later. Section 5A, inserted when the National Green Tribunal was created in 2010, gives any person aggrieved by a direction issued under Section 5 a right of appeal to the Tribunal. The National Green Tribunal Act 2010 made the Tribunal the forum for that appeal, as it made it the forum for appeals against environmental clearances and, after the Jan Vishwas amendments, for appeals against penalty orders, and the existence of a specialised appellate forum matters to how the direction power behaves: a closure direction can be tested quickly, on technical material, by a bench that includes expert members. It does not change the sequence, which remains direction first and adjudication afterwards, and that sequence is the point on which the debate about Section 5 turns. Defenders of the power answer that pollution is a continuing harm, that a factory discharging beyond its standards injures every day it operates, and that a regime requiring the state to litigate before it can stop the discharge would license the harm for the duration of the litigation. Critics answer that closure destroys livelihoods and capital on an executive finding that may rest on a contested sample or an unread inspection, and that the absence of a statutory pre-decisional hearing is a choice, not a necessity, since the Water and Air Acts manage to require notice before their boards direct closure. Both arguments are honestly held, and the section’s text supports the defenders on power while conceding nothing to the critics on procedure. What the record shows is that the power has been used most legitimately where it was tied to measured standards and published data, and most controversially where it was used as a substitute for the consent enforcement that the boards had failed to carry out over years.

The courts, reviewing closure directions under this Act and under the parallel direction powers in the Water and Air Acts, have supplied by adjudication some of the procedure the section omits. A direction that shutters an operating business is expected to rest on a disclosed foundation: an inspection or sampling record that the unit can see and answer, a measured exceedance or identified illegality rather than a general apprehension, and a proportion between the default and the remedy, so that a curable defect in an effluent plant attracts a direction to cure, on a timeline, before it attracts a direction to close. Directions founded on stale inspections, on samples taken without the prescribed procedure, or on the defaults of other units in a cluster have been set aside or read down, and the appellate route to the Tribunal under Section 5A has made such review faster and more technical than the writ jurisdiction it supplements. None of this converts Section 5 into a hearing-first power, and the executive retains the ability to act first in a genuine emergency, which on any view it must. What the case law has built around the section is a discipline of record: the state may close first and answer afterwards, but it must be able to answer, with measurements, when the afterwards arrives. Practitioners on both sides plan accordingly, the boards by building files that will survive the Tribunal, and industry by treating the inspection and the sample, rather than the courtroom, as the decisive theatre.

The prohibitions and the machinery of proof

Chapter III states the Act’s own prohibitions, and their structure confirms the delegation thesis from the other side. Section 7 provides that no person carrying on any industry, operation or process shall discharge or emit, or permit to be discharged or emitted, any environmental pollutant in excess of such standards as may be prescribed. Section 8 provides that no person shall handle or cause to be handled any hazardous substance except in accordance with such procedure and after complying with such safeguards as may be prescribed. Both sections are complete offences in form and empty in content: each forbids conduct by reference to a standard or procedure that exists only when rules prescribe it. Until the Environment (Protection) Rules, 1986 and the subject-specific rules laid down the schedules of standards industry by industry, Sections 7 and 8 prohibited nothing that could be measured. The parent Act creates the crime-shaped space; the rules fill it. This is why an Indian environmental lawyer asked what the law requires of a dyeing unit or a distillery does not open the Act at all, but opens the standards schedule applicable to that industry, the consent conditions under the Water and Air Acts, and the subject rules for its waste streams, every one of them subordinate legislation.

Section 9 addresses the accident, the event Bhopal taught the drafters to fear. It provides that where the discharge of any environmental pollutant in excess of the prescribed standards occurs or is apprehended to occur due to any accident or other unforeseen act or event, the person in charge of the place at which the discharge occurs or is apprehended to occur shall be bound to prevent or mitigate the environmental pollution caused or likely to be caused, and to intimate the fact of such occurrence or apprehension to the prescribed authorities or agencies, and to render all assistance to them. Sub-section (2) then obliges the authority receiving the information to cause such remedial measures to be taken as are necessary to prevent or mitigate the pollution, and sub-section (3) makes the expenses of remediation recoverable from the person concerned, with interest, as arrears of land revenue or of public demand. The section is short and it is the ancestor of every emergency obligation in the rules that followed, from the accident reporting in the Manufacture, Storage and Import of Hazardous Chemical Rules, 1989 to the crisis management machinery of the Chemical Accidents (Emergency Planning, Preparedness and Response) Rules, 1996, which erected crisis groups at the central, state, district and local levels around major accident hazard installations, charged with preparedness, response and the preparation of on-site and off-site emergency plans, so that the lonely duty of the person in charge under Section 9 acquired, a decade later, an institutional ladder to report up.

What must happen when a polluting accident takes place?

When a discharge beyond the prescribed standards occurs or is apprehended through an accident or unforeseen event, Section 9 binds the person in charge to prevent or mitigate the pollution, to intimate the prescribed authorities, and to render them assistance. The authority takes remedial measures, and recovers its expenses, with interest, from the person concerned as arrears of land revenue.

Sections 10 to 14 build the evidentiary machine without which the prohibitions could not be enforced. Section 10 empowers persons authorised by the Central Government to enter any place, at all reasonable times and with such assistance as they consider necessary, for the purpose of performing any of the functions of the Central Government entrusted to them, to examine and test equipment, industrial plant, records and registers, and to seize anything they have reason to believe may furnish evidence of an offence; deliberate obstruction of a person exercising this power, and failure without reasonable cause to comply with the accident and information duties, are themselves brought within the penalty net, after the Jan Vishwas substitution, through the monetary penalty that Section 14B attaches to the Sections 9, 10 and 11 cluster. Section 11 prescribes the procedure for taking samples of air, water, soil or other substance for analysis, and it is drafted like a chain-of-custody rule in a criminal statute, because under the original Act that is what it supported. The officer must serve notice on the occupier or the person in charge of the place of the intention to have the sample analysed, collect the sample in that person’s presence, place it in a container or containers which are marked and sealed and signed by both the officer and the person present, and send it without delay to the laboratory established or recognised under the Act; if the person wilfully absents himself, the officer seals and signs alone and records the refusal.

Section 12 empowers the Central Government to establish environmental laboratories, or to recognise any laboratory or institute as an environmental laboratory, to carry out the functions entrusted to it: the analysis of samples, the laying down of standardised methods of sampling and analysis, investigations into the parameters of environmental quality, and the publication of data. Section 13 provides for the appointment of Government Analysts, qualified as prescribed, to analyse samples sent to those laboratories. Section 14 completes the chain by giving the analyst’s report legal force: any document purporting to be a report signed by a Government Analyst may be used as evidence of the facts stated in it in any proceeding under the Act. The quartet of sections explains a feature of Indian environmental enforcement that outsiders find surprising, namely that litigation under this Act so often turns on sampling: whether notice was served, whether the container was sealed and signed, whether the laboratory was recognised, whether the analyst was qualified. A defect in the Section 11 procedure can dissolve a prosecution or a penalty, and both regulators and industry know it, which is one reason the compliance contest under this Act has always been as much about the integrity of measurement as about the fact of discharge.

How are pollution samples taken and tested under the Act?

Samples are taken under Section 11 by an authorised officer, who serves notice on the occupier, collects the sample in the occupier’s presence, and seals it in a container signed by both. It goes promptly to a laboratory recognised under Section 12, where a Government Analyst appointed under Section 13 tests it; the analyst’s report is evidence under Section 14.

Sections 18 to 21 of Chapter IV handle the state’s own position, and they are protective in ways a reader should notice. Section 18 bars suits, prosecutions and other legal proceedings against the government and its officers for anything done or intended to be done in good faith under the Act. Section 20 empowers the Central Government to require any person, officer, state government or authority to furnish information, reports and returns. Section 21 deems the members, officers and employees of an authority constituted under Section 3 to be public servants within the meaning of the Indian Penal Code when acting under the Act. Section 22 bars the jurisdiction of civil courts over anything done or any order or direction issued under the Act, channelling challenge to the appellate and constitutional remedies instead. None of this is exotic; it is the standard armour of a regulatory statute. But in a statute of this width the armour matters, because it means the vast delegated system operates with its officers shielded for good faith action, its decisions excluded from the ordinary civil courts, and its information demands backed by the penalty provisions. Section 19, the cognizance provision, belongs to the remedies discussion below, since it is the gate through which both the state and the citizen must pass.

The Act in one column, the law in the other

The argument of this article can be laid out in a single table. On one side stand the operative provisions of the Act itself, the powers and prohibitions Parliament enacted. On the other side stand the instruments made under those provisions, which are where the operative law for any real factory, project or coastline actually sits. The third column records what each instrument regulates, the fourth when it was made or last replaced, and the fifth answers the constitutional question the whole statute poses: whether the instrument can be changed without Parliament.

Operative provision of the Act	Instrument where the operative law sits	What it regulates	Made or last replaced	Changeable without Parliament
Section 3, with Rule 5 of the Environment (Protection) Rules	Environmental Impact Assessment Notification	Prior clearance for listed projects, categorisation, appraisal and public consultation	2006 (first issued 1994)	Yes
Section 3	Coastal Regulation Zone Notification	Construction and industry in the coastal strip up to 500 metres from the high tide line	2019 (first issued 1991)	Yes
Sections 6 and 25	Hazardous and Other Wastes (Management and Transboundary Movement) Rules	Generation, storage, transport, treatment, import and export of hazardous waste	2016 (first rules 1989)	Yes
Sections 6 and 25	Bio-Medical Waste Management Rules	Segregation, treatment and disposal of hospital and laboratory waste	2016 (first rules 1998)	Yes
Sections 6 and 25	Plastic Waste Management Rules	Plastic waste, producer responsibility and the single-use plastic prohibition	2016 (prohibition by amendment, 2022)	Yes
Sections 6 and 25	E-Waste (Management) Rules	Collection, recycling and producer responsibility for electronic waste	2022 (first rules 2011)	Yes
Sections 6 and 25	Battery Waste Management Rules	Used batteries and producer responsibility for their recovery	2022 (first rules 2001)	Yes
Sections 6 and 25	Solid Waste Management Rules	Municipal waste, segregation at source and generator duties	2016 (first rules 2000)	Yes
Sections 3, 6 and 25	Environment (Construction and Demolition) Waste Management Rules	Building and demolition debris, recycling and producer responsibility	2025 (first rules 2016)	Yes
Sections 6 and 25	Noise Pollution (Regulation and Control) Rules	Ambient noise standards, zones and loudspeaker and firecracker controls	2000	Yes
Section 8, with Sections 6 and 25	Manufacture, Storage and Import of Hazardous Chemical Rules	Threshold quantities, safety reports and accident duties for hazardous chemicals	1989	Yes
Section 8, with Sections 6 and 25	Rules for the Manufacture, Use, Import, Export and Storage of Hazardous Micro-Organisms and Genetically Engineered Organisms or Cells	Approval and containment of genetically engineered organisms and micro-organisms	1989	Yes
Sections 3, 6 and 25	Wetlands (Conservation and Management) Rules	Identification, notification and protection of wetlands	2017 (first rules 2010)	Yes
Sections 6 and 25	Environment (Protection) Rules and their schedules	Emission and effluent standards for industries and general discharge standards	1986, schedules revised by notification	Yes

Read down the fourth column and the pattern is the point. Every instrument in the table has been replaced at least once, several of them twice or three times, each replacement a complete restatement of the operative law for its subject, effected by notification. Read down the fifth column and the uniformity is the argument: yes in every row, because delegated legislation is by definition changeable without Parliament, subject only to the laying requirement of Section 26 and to the courts. The table also shows why the Act’s own amendment history is so misleading as a guide to the law’s development. Between 1986 and the Jan Vishwas Act of 2023, Parliament amended this statute only at the margins, most notably to insert the appellate Section 5A in 2010, while the operative law was transformed again and again underneath it. A historian who read only the parent Act would conclude that Indian environmental law stood still for four decades. A historian who read the gazette would conclude it never stood still at all. The series of which this article is part insists that the record around a statute matters more than its provisions; this statute is the limiting case, in which the provisions are a heading and the record is the law.

The standards system: where the numbers live

Since Sections 7 and 8 bite only against prescribed standards, the most consequential single instrument in the system is the one that prescribes them: the Environment (Protection) Rules, 1986, made under Sections 6 and 25 and brought into force with the Act itself. The Rules do three kinds of work. They state the procedure by which the Central Government restricts the location of industry: Rule 5 sets out the factors to be weighed, which include the standards of quality of the environment in an area, the maximum allowable concentration of pollutants, the emissions a proposed industry is likely to produce, its proximity to protected areas, reserves and human settlements, and the net adverse environmental impact it is likely to cause, and Rule 5(3) obliges the Government, when it proposes to impose a prohibition or restriction on the location of an industry or the carrying on of processes in an area, to publish notice of its intention, invite objections, and consider them before notifying the prohibition. The impact assessment notification of 2006 travelled this road, published in draft in September 2005 and finalised after objections a year later, which is why the consultation discipline examined in the clearance discussion below is not a courtesy but a rule-made condition of valid subordinate legislation in this field. The Rules also contain the standards themselves, in schedules that have grown industry by industry: emission and effluent standards for specified industries, developed over the years principally on the technical work of the Central Pollution Control Board and its expert committees, the Board’s programme of minimal national standards for industry categories having supplied the first generation of figures the schedules absorbed, and general standards for the discharge of environmental pollutants into inland surface waters, public sewers, land for irrigation and marine coastal areas, which apply where no industry-specific standard governs. Alongside the source standards stand the ambient standards, the quality the receiving environment must maintain: the national ambient air quality standards notified in 2009, which prescribe limits for twelve pollutants across industrial, residential and ecologically sensitive areas, and the ambient noise standards carried in the Noise Rules of 2000.

The standards system has a characteristic strength and a characteristic weakness, and both flow from its location in subordinate legislation. The strength is revisability at the speed of knowledge. When the evidence on a pollutant hardens, the standard can be tightened by amendment of a schedule, as happened when emission norms for thermal power plants were comprehensively revised by notification in December 2015, prescribing limits for particulate matter, sulphur dioxide, oxides of nitrogen and mercury together with water consumption norms for an entire sector in a single instrument, a legislative operation that as a parliamentary amendment would have consumed a session and emerged, if at all, in cruder form. The weakness is that the same ease serves dilution, and that compliance timelines written into such notifications have repeatedly been extended by further notification when industry pressed and the sector was unprepared, so that the standard on paper and the standard in force diverge in ways only a gazette watcher can track. The transmission belt between the schedule and the factory is the consent: the state board writes the applicable standards into the consent to operate under the Water and Air Acts, tests the discharge against them through the sampling machinery of Sections 11 to 14, and answers a breach with directions, compensation or prosecution. A number therefore lives three lives in this system, as a scientific recommendation in a committee, as a figure in a schedule, and as a condition in a consent, and it may tighten as it travels: the schedules state national floors, and a state board appraising a discharge into a stressed river stretch or a congested industrial cluster may write stricter limits into the individual consent, as the differentiated standard-making the proviso to Section 3(2)(iv) contemplates at the national level, so that two identical plants in different districts can lawfully face different numbers. A researcher who cites only the first or second life may be describing a law that no plant is yet obliged to obey. Precision about which life a standard has reached is the beginning of accuracy in this field, and its absence is the commonest defect of the secondary literature. Precision about which life a standard has reached is the beginning of accuracy in this field, and its absence is the commonest defect of the secondary literature.

Environmental clearance: the largest body of law the Act has produced

The instrument through which the Act touches the most valuable decisions is the environmental impact assessment notification. The Ministry of Environment and Forests issued the first such notification on 27 January 1994, under Section 3, making environmental clearance from the Central Government mandatory before work could begin on listed projects and expansions, across twenty-nine categories of industrial and development activity. An amendment in April 1997 added the public hearing, conducted through the state pollution control board, at which affected people could present their views on a project. The 1994 notification was replaced wholesale by the Environmental Impact Assessment Notification of 14 September 2006, issued under Section 3 read with Rule 5 of the Environment (Protection) Rules, 1986, and the 2006 instrument, amended many times but never replaced since, remains the governing code. Its architecture is the architecture of Indian project approval. Projects and activities are divided between Category A, appraised at the Centre by an Expert Appraisal Committee with clearance granted or refused by the Ministry, and Category B, appraised at the state level by a State Expert Appraisal Committee with clearance granted or refused by the State Environment Impact Assessment Authority. Category B is subdivided into B1, which requires an environmental impact assessment report and public consultation, and B2, which requires neither. The process runs in four stages: screening, which decides the category; scoping, which fixes the terms of reference for the study; public consultation, which comprises the public hearing and the consideration of written objections; and appraisal, at which the committee recommends and the authority decides. The clearance, when granted, is a conditional permission: it carries conditions on emissions, effluents, water use, green cover, waste handling and monitoring, with compliance reports owed by the project proponent, and it must exist before construction or expansion begins.

The read-across to the enforcing institutions matters here. A clearance under this notification is also not the only permission a project needs, and confusing it with the others is a frequent practical error. Land diversion from recorded forest requires a separate approval under the Forest (Conservation) Act, 1980, granted in stages by the Central Government on the advice of its forest advisory machinery, and a project that holds environmental clearance but lacks forest approval cannot lawfully break ground on the forest portion; wildlife clearance from the standing committee of the National Board for Wildlife is required for projects within protected areas and their eco-sensitive zones; and the consents of the state board follow their own track and their own timelines. The environmental clearance is the keystone of the arch, the permission that appraises the project as a whole, but the arch has other stones, each laid under a different statute or instrument, and the developer who treats the clearance letter as a general licence discovers the difference at the first inspection. The appraisal committees and clearance authorities created by the notification do not themselves inspect factories. Day-to-day enforcement of clearance conditions, and of the standards the clearance incorporates, falls to the Central Pollution Control Board and the state boards and committees whose consent machinery was built under the Water Act 1974 and the Air Act 1981, which is why a project proponent needs a consent to establish and a consent to operate from the state board alongside its clearance, and why a clearance condition so often operates in practice as a direction to the board to watch a particular parameter. The division of labour is characteristic of the umbrella design: the Act of 1986 generates the permission system by notification, and statutes seventeen and five years its senior supply the inspectorate that polices it.

The clearance system attracts two opposite and sincerely held bodies of criticism, and the stance this article takes requires both to be stated at strength. The case against the process, pressed by environmental lawyers and by many of the communities who appear at hearings, is that it has become a compliance ritual: the impact assessment report is commissioned and paid for by the project proponent, prepared by accredited consultants whose commercial interest lies in clearance, and structured to conclude that impacts are manageable; appraisal committees process large volumes of proposals in sittings that allow minutes per project; conditions are imposed in standard language and monitored largely through the proponent’s own compliance reports; and refusal is rare enough to be news. On this account the system produces the paperwork of assessment without the substance, and its real function is to convert a political decision to industrialise into an administrative finding that the environment has been considered. The case for the process, pressed by its defenders in the administration and by some of the same communities in a different mood, begins from a comparison: the clearance stage is the only point in Indian law at which a person who will live beside a mine, a port or a cement plant has a statutory right to notice, to the assessment documents, and to be heard before the decision is taken. Land acquisition has its own hearings under a different statute, and planning permissions have none of comparable generality. Abolish or hollow out the clearance process and the affected community does not get a better forum; it gets none, and must fall back on litigation after the fact, which is slower, dearer and confined to those who can reach a court. The honest verdict is that both accounts are true of the same institution. The process is frequently ritualistic in execution, and it is simultaneously the only procedural protection of its kind, which is why fights over its dilution are so intense: to weaken the hearing is not to reform a ritual but to remove the one moment at which the law requires power to listen before it decides.

The draft notification of 2020 is the standing proof of where environmental politics happens. The Ministry published a draft Environmental Impact Assessment Notification dated 23 March 2020, inviting objections and suggestions when it was placed in the gazette for public comment in April 2020, intending it to replace the 2006 notification entire. Among its proposals were a route for the regularisation of projects that had begun without prior clearance, the violation cases that the courts were separately addressing; a reduction of the public consultation period, with the notice and response window shortened from thirty days to twenty days; a shift of compliance reporting from half-yearly to annual; provisions under which violations would be taken cognizance of on the reports of the project proponent, government authorities or appraisal bodies rather than on information from the public; and a wider standardisation of terms of reference and clearance conditions. The response was of a scale that rule-making in India seldom produces: objections and comments arrived in very large volumes, from state governments, political parties, professional bodies, affected communities and individual citizens, through campaigns that treated a draft notification, correctly, as the real legislative event. The draft was never finalised. Two features of the 2006 system as it operates deserve record alongside the controversy, because they structure the daily work the draft proposed to alter. The appraisal committees at both levels are expert bodies constituted by the Ministry or the state authority for terms, organised sector by sector at the Centre, so that mining, industry, infrastructure, river valley and other projects go to different benches of specialists; and the Ministry has over the years issued standard terms of reference for recurring sectors, so that scoping for a common project type begins from a common template rather than from a blank page, a standardisation the 2020 draft proposed to deepen and critics read as the conversion of appraisal into checklist. The system’s defenders answer that standardisation is what consistency looks like in a high-volume regime, and that the alternative, bespoke terms for every project, is a recipe for the arbitrary variation that appellants then litigate. The 2006 notification continues to govern, amended in particulars. A proposed statute that died in Parliament would have been a parliamentary story; a draft notification that stalled under public objection is a story about a legislature that sits in the gazette, and about a public that has learned to watch it there. The episode is examined as a frequently asked question below, because its procedural moral generalises: under this Act, the objection period on a draft rule is one of the few guaranteed points of public entry into law-making, and it exists because the Environment (Protection) Rules require notice of intention and consideration of objections for restrictions of this kind, a discipline the Ministry imposes on itself through its own subordinate legislation.

How a clearance is won, held and lost

For the project developer and the consultant, who are among this article’s intended readers, the clearance system repays a walk through its working life, because the notification’s stages distribute power in ways the four-stage summary conceals. The proponent begins by commissioning the assessment: for Category A and B1 projects an environmental impact assessment report must be prepared by an accredited consultant organisation on terms of reference approved at the scoping stage, and the report’s quality, and its author’s commercial dependence on the client, are the standing subjects of the critique recorded above. The public consultation stage then splits into the hearing, conducted by the state pollution control board in the district where the project sits, presided over by the district magistrate or a representative, at which the proponent presents the project and the public records objections, and the written channel, under which representations go directly to the regulatory authority; the minutes of the hearing and the objections travel with the file to appraisal, and the proponent is expected to answer them in the final report with commitments the appraisal committee can convert into conditions. Appraisal is where the system concentrates its discretion. The expert committee examines the report, the hearing record and the site particulars, and may recommend clearance, recommend it with conditions, seek further study, or recommend rejection; the regulatory authority, the Ministry for Category A and the state authority for Category B, ordinarily follows the recommendation, and the clearance letter that issues is a schedule of obligations: specified emission and effluent limits tied to the standards schedules, water withdrawal caps, green belt and compensatory planting duties, waste handling requirements, monitoring and reporting duties, and, for some sectors, corporate environment responsibility expenditure. The clearance is granted for a stated validity period within which construction must commence, it is transferable to a successor proponent on intimation in the circumstances the notification allows, and it endures under surveillance: the proponent files compliance reports, the Ministry’s regional offices and the boards inspect, and the notification arms the authority to revoke or suspend a clearance procured by false or misleading information and to act on non-compliance with conditions, in parallel with the direction and compensation powers described elsewhere in this article.

Two features of that working life explain most of the litigation the system generates. The first is that the hearing record is the community’s one formal asset: objections minuted at the public hearing define the issues an appellate court or the Tribunal will later treat as having been before the decision-maker, and commitments extracted from the proponent in answer to them harden into clearance conditions whose breach is actionable, so that a community that appears organised, specific and early acquires legal leverage out of proportion to its resources, while one that learns of the project at the construction stage has lost the stage at which the law was listening. The second is that the clearance, once granted, is not a judgment but a licence under continuing supervision, whose conditions import the standards system into the project for its life; most post-clearance conflict is therefore not about whether the project should exist but about whether its conditions are being met, which is a question of monitoring data, and which returns the contest, once again, to the sampling and reporting machinery of the parent Act. The consultant who drafts the assessment, the officer who minutes the hearing and the analyst who signs the sample report are, between them, the human constitution of the clearance state, and the Act of 1986 is the instrument that employs all three.

The federal plumbing: what states do under a central Act

The Act is a central statute on subjects the Constitution largely assigns to the states, and the tension is structural rather than accidental. Water is a state subject, subject to the Union’s power over inter-state rivers; land and public health are state subjects; forests and the protection of wild animals and birds were moved to the Concurrent List by the Forty-second Amendment, which is why the Forest (Conservation) Act, 1980 could be enacted on the ordinary distribution of powers. Environment as such appears in no list, and the Act of 1986 reaches across all of them through Article 253 and the Stockholm decisions. The states were not consulted into a partnership by the text; they were organised into the system by the text’s machinery, and the machinery deserves description because it determines what a state government can and cannot do in environmental matters. A state cannot make rules under this Act: the rule-making powers in Sections 6 and 25 are the Central Government’s alone, and Section 23 expressly withholds the Section 25 power from delegation. What a state receives instead is function. The Central Government may delegate its powers and functions, other than authority-creation and rule-making, to a state government by notification, and does so for enforcement heads; the state pollution control boards, constituted under the Water Act, are authorised to lodge complaints under Section 19 and act as the Act’s inspectors and samplers across most of its field; the state-level clearance authorities under the impact assessment notification are constituted by the Central Government in consultation with the state government concerned, so that the state supplies the institution while the Centre retains the constituting power; and the coastal states administer the coastal notification through state coastal zone management authorities, which are themselves Section 3(3) authorities created by central order. Several states have legislated at the margins on subjects the umbrella does not occupy in detail, groundwater being the standing example, where state groundwater Acts coexist with the Central Ground Water Authority’s permit regime in a relationship that has never been fully theorised.

The federal bargain that results has a defensible logic and a standing grievance, and both should be recorded. The logic is that pollution crosses borders, that a race among states to offer the weakest standards would injure all of them, and that a uniform floor set centrally, with enforcement local, matches the physics of air and water. The grievance, voiced by state governments across parties for four decades, is that the floor has a way of becoming the whole building: the Centre prescribes the standards, constitutes the authorities, designs the clearance categories and reserves the rule book, while the states supply the inspectors, absorb the political cost of closures, and answer for failures of a system whose levers they do not hold. The Jan Vishwas allocation of seventy-five per cent of penalty receipts to the states is a late and partial acknowledgment of the imbalance, money following the enforcement burden without any corresponding transfer of the rule-making power. A reader who understands this division, central prescription and state enforcement under central instruments, understands why Indian environmental federalism is argued about in the language of administration rather than of constitutional text: the Constitution was barely engaged, because Article 253 and one short Act did the whole work by design.

Coasts, waste and the other rule families

The coastal regulation zone notification is the second great instrument, and its career shows the replacement rhythm of delegated law at its clearest. The first notification issued in February 1991, under Section 3, responded to the unregulated construction that was consuming the coastline by declaring the coastal stretches of seas, bays, estuaries, creeks, rivers and backwaters influenced by tidal action, up to five hundred metres from the high tide line on the landward side, to be a coastal regulation zone, and dividing it into categories: CRZ-I for ecologically sensitive areas, CRZ-II for substantially built-up municipal areas, CRZ-III for relatively undisturbed rural and other areas, and CRZ-IV for the water area and the island territories. Within the zone, classes of industry and construction were prohibited, restricted or permitted by category, with a no-development zone nearest the water. The 1991 notification was amended repeatedly through the nineteen nineties and the following decade, as tourism projects, ports, housing and courts contested its lines, and was replaced by the Coastal Regulation Zone Notification of 6 January 2011, which restated the scheme with a hazard line, special provisions for Kerala, Goa and the Mumbai islands among others, and a tightened regime for the CRZ-I areas. It was replaced again by the Coastal Regulation Zone Notification of 18 January 2019, which divided CRZ-III into CRZ-IIIA, for areas with a population density above 2,161 persons per square kilometre on the 2011 Census, where the no-development zone shrank from two hundred metres to fifty, and CRZ-IIIB, where it remained two hundred metres; fixed a no-development zone of twenty metres for islands close to the mainland and for backwater islands; released the frozen floor space index norms in CRZ-II areas so that building could proceed under the town planning rules in force; and delegated clearance for CRZ-II and CRZ-III projects to the state level, the Ministry retaining CRZ-I and CRZ-IV. The 2019 instrument also restated the water side of the zone, dividing CRZ-IV into the sea water area extending to the territorial limit and the tidal water bodies, creeks and backwaters whose banks carry their own regulation measured from the high tide line. Administration runs through the coastal zone management authorities noted in the federal discussion below, state bodies constituted under Section 3(3), which prepare the coastal zone management plans that translate the notification’s categories into maps for each stretch of coast, the maps being, in practice, the document on which every individual permission turns. Each of those changes is a policy decision of the first order about how much of India’s coast is buildable. None of them was taken by Parliament. The seed question on the coastal notification below answers the instrument’s content; the point here is its pedigree, which is Section 3 and nothing else.

The waste families reward a brisker treatment, because their shared structure matters more than their individual schemes, and the table above carries their dates. The hazardous waste line is the oldest: the first Hazardous Wastes (Management and Handling) Rules were made in 1989, in the shadow of Bhopal and alongside the Manufacture, Storage and Import of Hazardous Chemical Rules of the same year, which imposed threshold quantities, safety reports, safety audits and accident notification on major accident hazard installations, and the Rules for the Manufacture, Use, Import, Export and Storage of Hazardous Micro-Organisms and Genetically Engineered Organisms or Cells, also of 1989, which created the approval committees through which genetic engineering in India is still licensed. The hazardous waste rules were restated in 2008, principally to discipline transboundary movement in line with the Basel Convention, and again in 2016 as the Hazardous and Other Wastes (Management and Transboundary Movement) Rules, which govern authorisation by the state boards, manifest documentation for transport, treatment, storage and disposal facilities, and the import and export regime. Around that spine the Ministry built a separate rule family for each stream as it became politically salient: biomedical waste, first regulated in 1998 and restated in 2016 with colour-coded segregation at source; municipal solid waste, first regulated in 2000 and restated in 2016 with segregation into wet, dry and domestic hazardous streams and duties on generators; plastic waste, restated in 2016 with extended producer responsibility, and amended in 2021 to prohibit identified single-use plastic items, a prohibition that took effect on 1 July 2022; electronic waste, first regulated in 2011, restated in 2016 and replaced by the E-Waste (Management) Rules, 2022, which moved the system to registration of producers, manufacturers, refurbishers and recyclers and tradable extended producer responsibility certificates; batteries, first regulated in 2001 and replaced by the Battery Waste Management Rules, 2022; construction and demolition waste, first regulated in 2016 and replaced by the Environment (Construction and Demolition) Waste Management Rules, 2025, notified on 2 April 2025 and superseding the earlier rules from 1 April 2026, which introduce producer responsibility for large projects. Noise arrived by a different door: the Noise Pollution (Regulation and Control) Rules, 2000 prescribed ambient air quality standards in respect of noise for day and night across industrial, commercial, residential and silence zones, and regulate loudspeakers, public address systems and firecrackers, resting on the Act’s recognition of noise as an environmental pollutant and on the ambient standards amended into the Environment (Protection) Rules in the same period. The Wetlands (Conservation and Management) Rules, first made in 2010 and replaced in 2017, require states to identify and notify wetlands and prohibit activities within them, and eco-sensitive zone notifications around national parks and sanctuaries, issued site by site under Section 3, restrict industry, mining and construction in the buffer around protected areas. The enumeration is long because that is the finding: there is no subject in Indian environmental governance, from a hospital’s yellow bag to a wetland’s boundary, whose governing instrument is not traceable to a rule-making power in this short Act.

Enforcement on the ground: boards, compensation and the citizen

A statute that delegates everything must still answer the question of who acts when a rule is broken, and the Act’s answer is a layered one. At the base stand the pollution control boards: the Central Pollution Control Board advising the Union and co-ordinating, the state boards and the committees for the union territories granting consents, inspecting premises and prosecuting or penalising under their parent Acts, and all of them enforcing the standards and rules made under this Act, since a discharge standard prescribed in the Environment (Protection) Rules is the standard the state board writes into its consent and tests against its samples. The Central Board’s position in this structure is worth isolating, because it is the institution through which the Centre’s standards policy becomes national practice. Constituted under the Water Act, it advises the Central Government, co-ordinates the state boards and can require them to act, runs with them the national monitoring programmes for water and air quality whose measurements feed the pollution indices, the critically polluted area assessments and the compensation computations, maintains the technical committee work from which standards schedules are drafted, and issues directions under Section 5 of this Act under the Centre’s authorisation, most visibly in ordering continuous emission monitoring for the most polluting industrial categories and in directing time-bound action against defaulting units in clusters where state enforcement had stalled. Above the boards stands the Central Government with Sections 3 and 5, delegating to the Central Board, to Section 3(3) authorities and to state governments under Section 23 as the problem requires. Beside the executive stands the National Green Tribunal, which hears appeals under Section 5A, appeals against clearances under its own Act (for which this Act is a scheduled enactment), and original applications raising substantial questions relating to the environment arising out of this Act’s implementation, and which awards relief and compensation on the restitutionary principles its statute prescribes. The system’s characteristic sanction in practice, across these forums, has become environmental compensation: a monetary exaction, computed by the boards under formulae the Tribunal has approved, intended to price the harm and fund remediation rather than to punish. The Supreme Court’s order of 2013 in the Sterlite copper smelter litigation, imposing compensation of one hundred crore rupees for environmental harm from a plant that had operated without a valid renewal of consent while permitting it to continue in operation, is the emblematic instance: liability found, money exacted, production preserved, remediation charged to the polluter. The compensation practice has since been routinised into method. Working under directions of the Tribunal, the Central Pollution Control Board developed a methodology under which environmental compensation for a violation is computed from a pollution index assigned to the category of industry, multiplied by the number of days the violation continued and by factors for the scale of the operation and the sensitivity of its location, so that the exaction, while formulaic, scales with the gravity and duration of the default and can be applied by a board without a fresh adjudication in every case. State boards levy compensation on that basis for consent breaches, for operating without consent or clearance, and for failures ranging from untreated discharge to illegal dumping, and the amounts, unlike criminal fines under the old Section 15, are actually collected, because they are recoverable as public demands and because no board will renew a consent against an unpaid demand. It is within this compensation system, more than in the penalty sections themselves, that the practical price of polluting in India is set, and the Jan Vishwas fund architecture discussed below is best understood as Parliament catching up with a monetary practice the boards and the Tribunal had already built.

The citizen’s position under the Act is defined by Section 19, and it is narrower than most first-time readers expect. No court shall take cognizance of any offence under the Act except on a complaint made by the Central Government or any authority or officer authorised in that behalf, or, after the Jan Vishwas amendment added a third route, by the adjudicating officer, or by any person who has given notice of not less than sixty days, in the prescribed manner, of the alleged offence and of the intention to make a complaint, to the Central Government or the authorised authority or officer. The sixty-day notice is the design: it gives the state a final opportunity to act on the complaint itself before a private prosecution begins, which defenders describe as a filter against vexatious complaints and critics describe as a waiting period imposed on the party least able to wait, during which the discharge continues. In practice the citizen’s effective routes run wider than Section 19 suggests. A complaint to the state board or the Central Board can trigger inspection, sampling and directions; an application to the Tribunal can raise the matter without the criminal gate, the Tribunal’s original jurisdiction extending to substantial questions relating to the environment arising out of the implementation of the enactments in its schedule, among which this Act stands first in practice, and its remedial powers extending to restitution of the environment and compensation to victims; an appeal against a clearance lies to the Tribunal under its own Act, on the record the consultation stage created; a writ petition under Articles 32 or 226 can invoke the Article 21 jurisprudence; and objections at the public consultation stage, and on draft rules, engage the system before any violation occurs. For communities and for the journalists who document their evidence, the integrity of that paper trail is the substance of the right, which is why the working methods by which reporters keep source material intact matter to environmental enforcement: the methods journalists use to keep source documents safe with VaultBook are part of how complaints survive long enough to be heard. What a complainant should not expect is speed, or a private right to set the criminal law in motion without the statutory notice; and nothing in this article is legal advice for a specific grievance, which needs advice on its own facts. It is an explanation of the structure within which such advice operates.

Punishment: from prison to penalty

As enacted, the Act punished in the ordinary criminal way, and its penalty section was Section 15: whoever failed to comply with or contravened any provision of the Act, or the rules, orders or directions under it, was punishable, for each failure, with imprisonment for a term which could extend to five years, or with fine which could extend to one lakh rupees, or with both; if the failure continued, an additional fine of up to five thousand rupees could be imposed for every day of continuance after conviction; and if the failure continued beyond one year after conviction, imprisonment could extend to seven years. Section 16 governed offences by companies: the person in charge of and responsible to the company for the conduct of its business was deemed guilty unless the offence was proved to have been committed without that person’s knowledge or despite all due diligence to prevent it, and any director, manager, secretary or other officer with whose consent or connivance the offence was committed, or to whose neglect it was attributable, was likewise deemed guilty. Section 17 governed offences by government departments on the same pattern: the Head of the Department was deemed guilty subject to the same knowledge and diligence defence, and any other officer with whose consent or connivance the offence was committed, or to whose neglect it was attributable, was likewise liable. Prosecution required a complaint through Section 19’s gate, trial before a magistrate, and proof beyond reasonable doubt, and the near-universal assessment offered in the decriminalisation debates was that this machinery produced very few prosecutions relative to the volume of recorded non-compliance, while exposing officers and occupiers to the theoretical risk of prison for defaults that were frequently technical.

The Jan Vishwas (Amendment of Provisions) Act, 2023, Act 18 of 2023, which received assent on 11 August 2023 and amended forty-two Central Acts in a single decriminalisation exercise, rewrote this Act’s penal scheme, and the amendments took effect for the Environment (Protection) Act on 1 April 2024, the date appointed by notification G.S.R. 749(E) dated 17 October 2023. The substituted scheme is monetary and administrative. Section 14A attaches a penalty of not less than one lakh rupees and up to fifteen lakh rupees to contraventions of Sections 7 and 8 and of the rules, orders and directions under them, with an additional penalty of up to fifty thousand rupees for every day a contravention continues. Section 14B attaches a penalty of not less than ten thousand rupees and up to five lakh rupees to contraventions connected with Sections 9, 10 and 11, the accident, entry and sampling provisions, with an additional ten thousand rupees for every day of continuance. The substituted Section 15 is the residuary penalty, covering contraventions of any provision of the Act or of rules, orders and directions for which no penalty is otherwise provided, at not less than ten thousand rupees and up to fifteen lakh rupees, with an additional ten thousand rupees for every day of continuance. Section 15A fixes the penalty where the offender is a company at not less than one lakh rupees and up to fifteen lakh rupees, with an additional one lakh rupees for every day of continuance. Section 15B, the provision for government departments, abandons the fiction of the department’s imprisonment and prices the default personally: the Head of the Department is liable to a penalty equal to one month’s basic salary, unless it is proved that the contravention took place without the Head’s knowledge or despite all due diligence to prevent it, and an officer other than the Head whose neglect caused the contravention is likewise liable to a penalty equal to one month’s basic salary, subject to the same diligence defence.

The scale is worth seeing in operation, because the daily additions convert modest maxima into serious money over time. A contravention of the discharge prohibition in Section 7, attracting Section 14A, that continues for one hundred days exposes the offender to the base penalty of up to fifteen lakh rupees and to additional penalties of up to fifty thousand rupees a day, up to fifty lakh rupees across the period, a combined exposure of up to sixty-five lakh rupees for a single continuing default; a company in default under Section 15A faces daily additions of up to one lakh rupees, so that the same hundred days carry a combined exposure above one crore rupees. The adjudicating officer retains discretion within those ceilings, guided by the Section 15C factors, and the figures remain, for a large plant, small against project cost, which is the critics’ calibration point stated in arithmetic. The machinery for imposing these penalties is as significant as their amounts. Section 15C requires the Central Government to appoint adjudicating officers, not below the rank of Joint Secretary to the Government of India or of a Secretary to a state government, who hold an inquiry, after giving the person concerned a reasonable opportunity of being heard, and determine the penalty having regard to matters the section lists, including the population and the area impacted, the duration and frequency of the contravention, and any undue gain made from it. Section 15D gives an appeal to the National Green Tribunal within sixty days, and provides that the appeal shall not be entertained unless the appellant deposits ten per cent of the penalty imposed. Section 15E directs that penalties realised are credited to the Environmental Protection Fund, the fund established under the new Chapter IIIA, whose objects include the promotion of awareness, education and research for the protection of the environment and the advancement of the objects of this Act and of the Air Act, and of whose penalty receipts seventy-five per cent are allocated to the state governments; the Environmental (Protection) Fund Rules, 2026, notified in January 2026, govern the fund’s administration, its custody in the Public Account of India and its reporting. Section 15F preserves one criminal offence in the scheme, at its edge: failure to pay a penalty within ninety days of the order is punishable with imprisonment for a term which may extend to three years, or with fine which may extend to twice the amount of the penalty, or with both, and where the defaulter is a company, the persons in charge are deemed guilty subject to the knowledge and diligence defence. Section 19 was amended in step, adding the adjudicating officer to the list of those on whose complaint a court may take cognizance, which is the route by which a Section 15F prosecution begins.

The amendment is contested, and both cases deserve statement. The movement it belongs to is wider than this Act: the Water Act, the senior statute of the cluster, was amended in 2024 on the same philosophy, substituting adjudicated monetary penalties for imprisonment across most of its offence provisions in the states to which that amendment extends, so that the direction of Indian pollution law as a whole is from the magistrate’s court to the adjudicating officer’s desk. The Union’s case, made in the Jan Vishwas Bill’s statement of objects and repeated across the forty-two Acts it amended, is one of proportion and throughput: imprisonment for contraventions that are overwhelmingly failures of paperwork, monitoring and marginal exceedance deters investment and honest enterprise out of proportion to the harm, clogs magistrates’ courts with prosecutions the state seldom wins, and is better replaced by penalties that are swift, certain and scaled, imposed by a senior officer after a hearing and credited to environmental purposes. The critics’ case, made by environmental organisations and opposition members during the Bill’s passage, is that decriminalisation misreads the problem: the old system’s failure was not excessive severity but absent enforcement, a five-year maximum that was almost never imposed cannot have been the obstacle to compliance, and the removal of prison from the scheme, capped penalties measured in lakhs against projects measured in thousands of crores, and the conversion of crime into a fee together announce to a calculating polluter that violation is a purchasable input. The verdict this article reaches is that the critics have the better of the argument on the ceiling and the government has the better of it on the machinery. A penalty regime that is actually used will deter more than a prison regime that is not, and the adjudicating officer, the deposit-backed appeal and the fund are genuine institutional improvements; but a maximum of fifteen lakh rupees, unindexed and identical for a workshop and a refinery, is not a deterrent price for large industry, and the statute that delegates everything else could at least have delegated a rational scale. As with the delegation question itself, the defect is not the direction of the reform but the absence of calibration in its execution.

The courts and the width of the Act

The judiciary’s contribution to this Act’s meaning falls into three bodies of doctrine: the principles the courts read into environmental decision-making, the width they have allowed the direction and delegation powers, and the long litigation over clearance granted after the fact. The principles came first chronologically and are the most settled. In Vellore Citizens Welfare Forum v. Union of India, decided in 1996, a case concerning tanneries discharging untreated effluent into the river Palar in Tamil Nadu, the Supreme Court held that the precautionary principle and the polluter pays principle are part of the law of the land, to be read with Articles 21, 47, 48A and 51A(g) of the Constitution: environmental measures must anticipate and prevent harm rather than wait for proof of damage, the burden of showing that an action is environmentally benign rests on the actor, and the cost of restoring degraded environment falls on the polluter. In Indian Council for Enviro-Legal Action v. Union of India, decided the same year, arising from the chemical pollution of Bichhri village in Rajasthan by plants producing toxic chemicals, the Court applied polluter pays to make the industries bear the cost of remediation of the contaminated soil and water. In M.C. Mehta v. Kamal Nath, decided in 1997, arising from a motel company’s diversion of the river Beas and the damage its works caused in the Kullu valley, the Court held that the public trust doctrine is part of the law of the land: the state holds natural resources such as rivers, forests and the seashore as trustee for the public, and cannot commit them to private use in breach of that trust, a doctrine that has since framed challenges to the alienation of lakes, wetlands and common lands across the country. A decade earlier, in the oleum gas leak litigation that followed the escape of oleum gas from Shriram Foods and Fertiliser Industries in Delhi in December 1985, M.C. Mehta v. Union of India, decided in 1987, the Court had propounded the rule of absolute liability for enterprises engaged in hazardous activity, a doctrine stricter than the strict liability of English law because it admits no exceptions; that principle, and the compensation jurisprudence that grew from the Bhopal and oleum litigation, is owned by the companion history of the disaster legislation and is noted here only because it is contemporaneous with this Act and forms the liability backdrop against which its prohibitions operate. These principles do not appear in the Act’s text. They govern its administration anyway, because the National Green Tribunal is directed by its own statute to apply sustainable development, the precautionary principle and polluter pays in its orders, and because the constitutional courts test executive action under the Act against them. Together, the principles form the common law of the Act’s administration, and their absence from the statute’s text is the standing reminder that this Act’s law is made in three places at once: the gazette, the rule book and the reports of the courts.

On the width of the powers, the courts have been permissive in a consistent direction. The continuing mandamus in the M.C. Mehta proceedings treated Section 3 and Section 5 as adequate authority for measures of great specificity: the conversion of Delhi’s public transport fleet to compressed natural gas, the relocation of industries from the capital, and in the Taj Trapezium matter, decided in 1996, the direction that coal and coke based industries around the Taj Mahal change over to natural gas or relocate, enforced through the machinery of this Act and the boards. A legislature that had enacted standards for sulphur dioxide in the Taj Trapezium Zone would have taken a session to do what the direction power did by order. Challenges to the delegation itself, on the ground that Parliament had abdicated its function, have never succeeded against this Act, consistently with the general Indian doctrine that delegation is valid where the parent statute states a policy, and Section 3(1) states one in terms the courts have treated as sufficient guidance. The breadth of Section 3 received its most consequential modern reading in the post facto clearance litigation, to which this article turns, because that litigation is where the Act’s design, its clearance instrument and its penalty theory all collide. One further order belongs in this account before that litigation, because it shows a court reaching for Section 3(3) as a reform instrument in its own right. In Lafarge Umiam Mining v. Union of India, decided in 2011, a case concerning limestone mining and forest diversion in Meghalaya, the Supreme Court directed the Central Government to appoint a national environmental regulator under Section 3(3), charged with appraisal of projects, monitoring of conditions and enforcement, on the reasoning that the existing arrangement of ad hoc expert committees within the Ministry lacked the independence and continuity the clearance function required. The direction was not carried into effect; appraisal remains with committees constituted under the notification, and the episode stands as the clearest available demonstration that Section 3(3) is understood by the courts themselves as a standing power to redesign the regulatory state, whose non-use is a policy choice of the executive and not a limit of the Act.

The question is simple to state. The impact assessment notification makes prior clearance a condition of lawful commencement. Projects in large numbers commenced anyway, through ignorance, through calculation, or through the pressure of construction finance, and their proponents then sought clearance for what already stood built. Is a clearance granted after the fact a clearance at all? In Common Cause v. Union of India, decided in 2017, a case of illegal iron ore mining in Odisha, the Supreme Court held that a lessee who mined without environmental clearance acted illegally, directed recovery of the full value of the illegally mined ore as compensation, and treated clearance as a condition precedent whose absence could not be cured by later grant, while permitting mining to resume under fresh clearance and payment. In Alembic Pharmaceuticals v. Rohit Prajapati, decided in 2020, where pharmaceutical units in Gujarat had operated for years on the strength of a state circular purporting to allow clearance after commencement, the Court struck the circular down and held that the concept of ex post facto clearance is alien to environmental jurisprudence, since assessment after construction defeats the purpose of assessing at all; yet it declined to order the units closed, and instead moulded relief by directing payment of environmental compensation under Article 142, a pattern, prior clearance as the rule and remediation rather than demolition as the usual relief, that recurs throughout this line of cases. Other benches took a different view of the margin: in Pahwa Plastics v. Dastak NGO and in D. Swamy v. Karnataka State Pollution Control Board, the Court treated post facto clearance as capable of grant in exceptional cases on stringent terms, rather than as a contradiction in terms.

The executive, meanwhile, had acted on the second view. By notification S.O. 804(E) dated 14 March 2017, issued under Section 3, the Ministry opened a one-time window of six months within which projects that had commenced without prior clearance could apply for clearance, subject to appraisal, assessment of environmental damage, a remediation plan and compensation; the applications taken in that window were appraised with terms of reference that included the damage assessment and a remediation and augmentation plan secured by bank guarantee, and the window, though framed for six months, was extended in operation into the following year as appraisals proceeded; and by an office memorandum dated 7 July 2021 it issued a standard operating procedure that converted the window into a standing mechanism for handling violation cases as they arose. In Vanashakti v. Union of India, decided on 16 May 2025, a bench of two judges struck down both instruments, holding ex post facto clearance alien to environmental law and the 2021 procedure an impermissible dilution of the notification it purported to administer. On review, a bench of three judges, by a majority of two to one in a judgment delivered on 18 November 2025, recalled that decision as having been rendered without noticing the Pahwa Plastics and D. Swamy line and the relief actually moulded in Common Cause and Alembic. The writ petitions were then heard afresh, and in the judgment delivered on 29 July 2026, a three-judge bench speaking through Bagchi J. settled the matter in terms that repay attention because they are, at bottom, a judgment about this Act. Prior environmental clearance remains the rule, and the stages of screening, scoping, public consultation and appraisal are designed to operate before construction, because consequences must be evaluated before damage becomes irreversible. Payment of a penalty under the amended Section 15 does not launder the illegality: the Jan Vishwas Act decriminalised the penal consequences of violations, but it did not alter the architecture of the clearance notification or authorise the administrative regularisation of illegal projects, which remain liable to restoration of the status quo ante, including closure, demolition where necessary, remediation and recovery of environmental costs. Section 3, however, confers power of the widest amplitude, and read with the power to amend instruments under the general law of delegated legislation, it permits the Union, by a statutory notification, to create a narrowly tailored and time-bound exception for exceptional cases justified by supervening public interest, provided proportionality is satisfied and the precautionary principle is preserved. Applying that test, the Court upheld the notification of 14 March 2017 as valid delegated legislation addressed to a closed class of existing violations, and quashed the office memorandum of 7 July 2021, which was an administrative instruction rather than legislation, which created a perpetual mechanism rather than a limited scheme, and which therefore failed the tests of proportionality and reasonableness under Articles 14 and 21. Clearances already granted under either instrument remain valid unless challenged on independent grounds; no fresh applications may be entertained under either; and the Union stands restrained from granting post facto clearance by administrative order in future, any such regime being required to come through a notification under Section 3. The jurisprudence of the Supreme Court on the environment carries the wider canvas of which this litigation is one panel. For this article’s argument the holding’s deepest point is its first move: the legality of the largest question in Indian environmental administration was decided by construing the width of a delegation clause, which is what it means to say that under this statute the constitutional action is in the subordinate law.

Section 24 and the neighbours: an umbrella with one deliberate hole

Section 24 states the Act’s relationship with the rest of the statute book, and it contains a surprise that rewards a pillar article’s attention. Sub-section (1) provides that, subject to sub-section (2), the provisions of this Act and the rules or orders made under it shall have effect notwithstanding anything inconsistent contained in any enactment other than this Act: the standard overriding clause, which makes the umbrella prevail over older inconsistent law. Sub-section (2) then reverses the polarity for punishment: where any act or omission constitutes an offence punishable under this Act and also under any other Act, the offender found guilty shall be liable to be punished under the other Act and not under this Act. The Act that overrides everything thus declines to punish where another statute also punishes, a deliberate anti-duplication rule that channels prosecution into the more specific statute, usually the Water Act or the Air Act with their board-led prosecution machinery, and reserves this Act’s penal provisions for the field the others do not cover. After the Jan Vishwas substitution the point has changed its practical weight, since this Act penalises monetarily through adjudication while the Water and Air Acts retain their own imprisonment provisions for their offences, but the structural lesson survives the amendment: Parliament designed the umbrella to supply standards, machinery and gap-filling force across environmental law, not to swallow the neighbouring statutes.

Can a person be punished under both this Act and another law for the same act?

No. Section 24(2) provides that an act punishable under this Act and also under another Act attracts punishment under the other Act and not under this Act. The Act overrides inconsistent law on standards and machinery, but it yields on punishment, so one act attracts one prosecution, under the more specific statute.

The working relationship with the Water and Air Acts follows the same pattern of supplementation rather than replacement. The boards constituted under those Acts are the enforcement arm for the standards this Act’s rules prescribe; a state board’s consent under the Water Act will incorporate the effluent standards in the schedules to the Environment (Protection) Rules, and its consent under the Air Act the emission standards, so that a breach of a rule made under this Act’s Section 6 becomes actionable through the older Acts’ consent and direction powers as well as through Section 5. Where the older Acts cannot reach, because the pollutant is noise, or the medium is land, or the problem is a waste stream or a coastline, this Act reaches alone. That division of labour, senior statutes supplying institutions and the 1986 Act supplying omnibus authority, is the practical meaning of the umbrella, and it is why repealing or weakening any one of the three statutes would tear a fabric none of them constitutes by itself.

Environmental law by gazette: the delegation question

Everything in this article converges on one constitutional question, and the series’ stance discipline requires it to be argued at full strength on both sides before a verdict is given. The case for the delegation, made by administrators and by the courts that have sustained it, is that environmental standards are technical facts wearing legal dress. The safe concentration of sulphur dioxide in ambient air, the biochemical oxygen demand a river reach can absorb, the manifest form that keeps a tanker of spent solvent accounted for between a factory in Vapi and a disposal facility in Ankleshwar: these are not propositions a legislature can debate into correctness, and they change as toxicology, monitoring technology and industrial practice change. A Parliament that had to amend a statute each time a standard moved would either freeze the standards, and govern a changing industrial economy with the toxicology of 1986, or spend its sessions on schedules. Delegation to a ministry advised by a technical board, with draft publication and objections for the restrictive instruments, is on this account not an abdication but the rational division of labour of a modern regulatory state, and the proof offered is comparative: every mature environmental regime, from the American Clean Air Act’s agency standards to the European Union’s implementing measures, lodges its numbers in subordinate instruments for the same reason. The Indian variant adds the argument from federalism already noticed, that a single rule book prevents a competitive descent among states.

The case against is not an argument against delegation but against its extent and its unchecked character under this Act, and it has three limbs. The first is amplitude: Section 3 does not delegate a defined power to set standards within stated limits, but a power to take all measures the executive deems necessary for the environment, illustrated by a list that ends with a residuary head wider than its items. Indian courts have sustained the delegation because Section 3(1) states a policy, but a policy stated at the level of protecting and improving the quality of the environment disciplines almost nothing, and the sustainable challenges have had to be brought instead as attacks on particular instruments, case by case, after the fact. The second limb is symmetry of ease: a notification can narrow a protection exactly as easily as it can widen one, and the narrowing kind attracts a fraction of the attention. The reduction of the coastal no-development zone for the denser rural coast in 2019, the successive extensions of compliance timelines for industrial emission standards, and the dilution proposals in the 2020 draft all travelled the same procedural road as the tightenings, and none required a minister to defend the change on the floor of either House against an amendment and a vote. The third limb is the weakness of the check that exists. Section 26 requires rules made under the Act, and the orders constituting authorities, to be laid before each House of Parliament for thirty days, and empowers Parliament to modify or annul them, without prejudice to anything already done; in practice the laying requirement is a formality observed in bulk, annulment is a dead letter, and the parliamentary committees on subordinate legislation examine a small fraction of the instruments that govern the field. A control that requires the legislature to react within a session, against an instrument already in force and already relied upon, with the burden of organising a majority against the government of the day, is not a control in any sense that would comfort the critics. Both Houses maintain committees on subordinate legislation, and those committees do examine rules for excess of power, delay in laying and drafting defects, and have over the decades produced reports of real quality on particular instruments; but their scrutiny is selective, retrospective and advisory, spread across the entire output of the Union government, and it has never operated as a systematic examination of environmental instruments as a class. Nothing in the Act requires a statement of objects and reasons for a notification, a regulatory impact assessment, a post-publication review after a stated interval, or a sunset after which a standard lapses unless re-made on fresh evidence, disciplines that comparable systems impose in varying combinations precisely because their designers understood that delegated power without a review rhythm drifts.

The verdict this article reaches follows from the evidence assembled in its own sections. Delegation of standard-setting under this Act was necessary, remains necessary, and is not the scandal; the standards system could not exist in statutory form. The scandal, if the word is not too strong, is the absence of any working middle layer of scrutiny between the ministry’s drafting table and the gazette: no statutory obligation to publish drafts of the major instruments with a statement of reasons and a response to objections, of the kind Rule 5 imposes for location restrictions and the Ministry observed, with famous consequences, for the 2020 draft; no specialised parliamentary examination with the power to delay; and no discipline of periodic review that would force dormant dilutions into the open. The 2020 episode is the proof of concept for the reform rather than an argument against the system: where a draft was published and objections invited, the public came, the arguments were made in the open, and the instrument was not finalised in its proposed form. Environmental law by gazette is a permanent feature of Indian government, because the alternative is environmental law by paralysis. The task the Act leaves undone, forty years on, is to build around the gazette the procedural constitution that a legislative process would have supplied by default: publication, reasons, response, review. Until that is built, the most important environmental statute in India will continue to operate as it began, as a twenty-six section delegation of the environmental future to whoever holds the pen at the Ministry, checked episodically by courts, and watched, by those who have learned the lesson of 2020, at the only place it is in fact made.

Errors this Act attracts

Because the Act is short and its progeny are vast, the secondary literature makes a predictable set of mistakes, and a pillar article earns its keep by correcting them expressly. The first is to describe the impact assessment regime as part of the Act: it is not in the Act at all, which nowhere mentions clearance, appraisal or public hearing, the entire system resting on a notification under Section 3 that could be, and in draft in 2020 nearly was, replaced without touching a line of the statute. The second is to quote the penalty in Section 15 as imprisonment up to five years without noting that the Jan Vishwas amendments substituted the scheme with monetary penalties from 1 April 2024, an omission that reverses the practical advice the passage exists to give. The third is to give superseded notification provisions as the law: the coastal categories of 1991 or 2011 quoted after the 2019 replacement, the hazardous waste rules of 2008 quoted after 2016, the e-waste rules of 2016 quoted after 2022. The fourth is to credit the Act with the boards: the Central and state pollution control boards are creatures of the Water Act of 1974, extended by the Air Act of 1981, and this Act created neither, though it arms both. The fifth is to say the Act bans pollution: it bans discharge in excess of prescribed standards and handling of hazardous substances otherwise than by the prescribed procedure, and the difference between a ban and a standard is the difference between this statute and the statute most readers imagine they are citing. Each error is a small instance of the article’s large point. Where the law lives in instruments, accuracy lives in the instruments, and a summary of the parent Act, however careful, is a map of a country whose cities are elsewhere.

Using the Act: a reader’s map

The brief for this article names three readers, and the statute serves each of them at a different point of entry, which a map may usefully state before the questions begin. The project developer and the consultant enter through the instruments, not the Act: the first task in any engagement is to identify which notifications and rule families the project attracts, whether it falls in a clearance category and which, whether its site touches a coastal zone, an eco-sensitive zone or a notified wetland, which waste streams its processes will generate and under which rules each is authorised, and which standards schedules its emissions and effluents must meet, since the Act will answer none of those questions and the instruments will answer all of them. The affected community and the activist enter through the procedural doors the system guarantees: the public consultation stage of the clearance process, where objections must be made early, specifically and on the record; the objection windows on draft rules and notifications, where the 2020 episode proved that volume and organisation can stop an instrument; the complaint to the board, which sets the inspection and sampling machinery in motion; and, after a violation, the sixty-day notice under Section 19 and the application to the Tribunal. The researcher enters through the gazette itself, and the discipline is chronological: for any proposition about Indian environmental law, the operative question is which instrument, in which version, on the relevant date, because the parent Act’s stability is a standing invitation to the error this article has tracked throughout, the citation of a framework as though it were the law. Read in that order, instruments first, procedures second, framework last, the Act becomes what it was designed to be: not a code to be memorised but a constitution for a body of law that lives elsewhere, whose twenty-six sections reward study precisely because they explain where the rest of the law comes from and how it can be changed.

Conclusion

The Environment (Protection) Act, 1986 is the shortest important statute in Indian environmental law and, by the measure of what depends on it, the most important. It took from Stockholm a mandate, from Bhopal a spur, from Article 253 a reach across the federal distribution, and it converted all three into a delegation: a definition wide enough for any medium, a power wide enough for any measure, prohibitions that wait upon prescribed standards, a direction power that can close an industry and cut its power, a machinery of sampling and analysis to prove breaches, and a set of instruments, the clearance notification, the coastal notification and the waste and standards rules, in which the whole operative content of Indian environmental law resides and from which it is revised, tightened, diluted and remade without parliamentary vote. The courts have supplied the principles the text omits, precaution, polluter pays and the rule that clearance precedes construction, and have read the delegation at its full width while quashing its perpetual amnesty. The Jan Vishwas amendments have converted its punishments from prison to price, an improvement in machinery carrying an unpriced ceiling. To read this Act well is to learn the series’ lesson in its purest form: the provisions are the heading, the record around them is the law, and the citizen who wants to know what Indian environmental law requires must learn to read the gazette as attentively as the statute book, because the gazette is where Parliament, in 1986, arranged for the law to be written.

Frequently Asked Questions

Q: Why is the Environment Protection Act called umbrella legislation?

The Act is called umbrella legislation because it shelters the whole of environmental law rather than one part of it. The Water Act of 1974 governs water pollution and the Air Act of 1981 governs air pollution, each tied to a single medium. The Environment (Protection) Act, 1986 defines the environment itself, in Section 2(a), as water, air and land and the interrelationship among and between them and human beings, other living creatures, plants, micro-organisms and property, and it vests its powers in the Central Government over environmental matters generally. Noise, groundwater, coastlines, hazardous substances and every waste stream have been brought under law through instruments made under this Act, which is why it functions as the canopy under which the medium-specific statutes and the rule families operate.

Q: How is the Environment (Protection) Act different from the Water Act and the Air Act?

The three statutes differ in medium, machinery and origin. The Water Act of 1974 addresses pollution of water, creates the central and state pollution control boards, and runs a consent system for discharges into streams, wells and sewers. The Air Act of 1981 addresses pollution of air, works through the same boards, and requires consent for industrial plants in declared air pollution control areas. The Environment (Protection) Act, 1986 addresses the environment as a whole, vests power in the Central Government rather than in the boards, and supplies the standards, rules, authorities and directions under which the boards largely work. In practice the three interlock: the boards enforce, through their Water and Air Act consents, standards prescribed under the 1986 Act and its rules.

Q: What directions can the Central Government issue under the Environment Protection Act?

Under Section 5, the Central Government may issue directions in writing to any person, officer or authority, and the person or authority is bound to comply. The section’s Explanation makes the reach explicit: a direction may order the closure, prohibition or regulation of any industry, operation or process, and the stoppage or regulation of the supply of electricity or water or any other service. In practice the power is exercised through the Central Pollution Control Board, through authorities constituted under Section 3(3), and through delegated officers, for purposes ranging from closing individual polluting units to the moratorium imposed on new projects in critically polluted industrial clusters and the graded response measures applied to the capital’s air. A person aggrieved by a direction may appeal to the National Green Tribunal under Section 5A.

Q: Why does the Act itself contain almost no pollution standards?

The absence is a deliberate drafting choice. Section 7 prohibits the discharge of any environmental pollutant in excess of such standards as may be prescribed, and the word prescribed, defined in Section 2(g), means prescribed by rules made under the Act. Parliament reasoned, in effect, that standards are technical quantities: they differ by industry, by pollutant and by receiving medium, and they must be revised as science and technology change, which no legislature can do by repeated amendment. The numbers therefore live in the Environment (Protection) Rules, 1986 and their schedules, which carry industry-specific emission and effluent standards and general standards for discharge, supplemented by ambient standards such as the national ambient air quality standards notified in 2009. To know the binding limit for a plant, a reader consults the schedule and the consent, not the Act.

Q: Which rules are made under the Environment Protection Act?

The principal families are the Environment (Protection) Rules, 1986 themselves, carrying the standards schedules; the Environmental Impact Assessment Notification, first issued in 1994 and replaced in 2006; the Coastal Regulation Zone Notification, first issued in 1991 and replaced in 2011 and 2019; and subject rules that include the Manufacture, Storage and Import of Hazardous Chemical Rules, 1989, the rules for genetically engineered organisms of 1989, the Chemical Accidents Rules, 1996, the Noise Pollution (Regulation and Control) Rules, 2000, the Wetlands Rules, replaced in 2017, and the waste families: hazardous and other wastes in 2016, biomedical waste in 2016, plastic waste in 2016, solid waste in 2016, electronic waste replaced in 2022, battery waste in 2022, and construction and demolition waste replaced in 2025.

Q: What happens at a public hearing for environmental clearance?

The public hearing is the central event of the public consultation stage of the Environmental Impact Assessment Notification, 2006, required for Category A and Category B1 projects. The state pollution control board conducts it in the district where the project is proposed, after public notice, and the district magistrate or a representative presides. The project proponent presents the project and its assessment findings, and any person present may state objections and suggestions, which are recorded in minutes that travel with the application to the appraisal committee. The proponent must address the concerns in the final assessment report, and the appraisal committee may convert the answers into clearance conditions. Written representations may also be sent to the regulatory authority. Category B2 projects are exempt from public consultation altogether.

Q: What is environmental clearance and who grants it?

Environmental clearance is the prior permission that the Environmental Impact Assessment Notification, 2006, issued under this Act, requires before a listed project or activity can begin work, expand or change its product mix. The notification’s schedule covers sectors such as mining, industry, energy, infrastructure and construction. Category A projects, the largest, are appraised by an Expert Appraisal Committee at the Centre and cleared or refused by the Union Ministry of Environment, Forest and Climate Change. Category B projects are appraised by a State Expert Appraisal Committee and cleared or refused by the State Environment Impact Assessment Authority. Clearance is granted on conditions covering emissions, effluents, water use, waste and monitoring, and a clearance obtained after construction has begun is not the same instrument in law, as the post facto litigation discussed in this article shows.

Q: What did the draft EIA Notification of 2020 propose and why was it opposed?

The draft notification, dated 23 March 2020 and published for objections and suggestions in April 2020, proposed to replace the 2006 notification. Its contested proposals included a route for regularising projects that had begun without prior clearance, a shortening of the public consultation notice and response period from thirty days to twenty days, a change of compliance reporting by project proponents from half-yearly to annual, and provisions under which violations would be taken cognizance of on reports from the proponent, government authorities or appraisal committees rather than on information from the public. Opposition came from state governments, political parties, environmental organisations, affected communities and citizens, in very large volumes of objections, on the ground that the draft diluted the one statutory hearing a community receives. The draft was not finalised, and the 2006 notification continues to govern.

Q: Is post facto environmental clearance legal in India?

Prior clearance is the rule, and clearance granted after a project has begun is lawful, if at all, only within narrow limits. In Common Cause in 2017 and Alembic Pharmaceuticals in 2020, the Supreme Court treated clearance as a condition precedent and described ex post facto clearance as alien to environmental jurisprudence, while moulding relief towards compensation and remediation rather than demolition. The Ministry’s one-time notification of 14 March 2017, which opened a six-month window for existing violators to seek clearance with damage assessment and remediation, was upheld by the Supreme Court on 29 July 2026 as valid, narrowly tailored delegated legislation under Section 3. The standing standard operating procedure created by office memorandum in July 2021 was quashed in the same judgment as a perpetual amnesty created without legislative form. Payment of a penalty does not by itself regularise a project.

Q: Can an ordinary person file a complaint under the Environment Protection Act?

Yes, but through a gate the Act designs deliberately. Section 19 provides that no court shall take cognizance of an offence under the Act except on a complaint by the Central Government or an authorised authority or officer, by the adjudicating officer added in 2023, or by any person who has first given notice of not less than sixty days, in the prescribed manner, of the alleged offence and of the intention to complain, to the Central Government or the authorised authority. The notice gives the state an opportunity to act itself before a private prosecution begins. Outside the criminal route, an ordinary person may complain to the state board or the Central Board, which can inspect, sample and issue directions, object at a public consultation, or approach the National Green Tribunal.

Q: What role do State Governments play under the Environment (Protection) Act?

State governments enforce the Act but cannot rewrite it. The rule-making powers in Sections 6 and 25 belong to the Central Government alone, and Section 23, which allows the Centre to delegate its functions, expressly withholds the rule-making power and the power to constitute authorities. What states supply is the machinery of enforcement: their pollution control boards, constituted under the Water Act, inspect premises, take samples, write the Act’s standards into consents, and are authorised to complain under Section 19. State-level clearance authorities are constituted by the Centre in consultation with the state government concerned, and state coastal zone management authorities administer the coastal notification. The Jan Vishwas settlement acknowledges the burden fiscally, allocating seventy-five per cent of penalty receipts under the new Environmental Protection Fund to the states.

Q: How was the Central Ground Water Authority created under this Act?

The Central Ground Water Authority exists because Section 3(3) lets the Central Government constitute an authority by gazette order, without a separate statute. Groundwater had no central regulator, extraction being governed by land ownership and state measures. In M.C. Mehta v. Union of India, by an order of 10 December 1996, the Supreme Court directed the Central Government to constitute the Central Ground Water Board as an authority under Section 3(3), with the power to issue directions under Section 5 and to invoke the Act’s penal provisions, for the regulation and control of groundwater development and management. The Government complied by notification S.O. 38(E) dated 14 January 1997. The Authority built on that foundation its system of no-objection certificates for extraction, governed by guidelines last comprehensively notified on 24 September 2020.

Q: What did the Jan Vishwas Act change about environmental offences?

The Jan Vishwas (Amendment of Provisions) Act, 2023, whose amendments to this Act took effect on 1 April 2024, replaced the criminal penalty scheme with monetary penalties for most contraventions. New Sections 14A and 14B and substituted Sections 15 to 15F fix penalties that run, according to the contravention, from ten thousand rupees to fifteen lakh rupees, with daily additions for continuing defaults, higher exposure for companies under Section 15A, and a personal penalty for heads of government departments under Section 15B. Penalties are imposed by adjudicating officers of senior rank after a hearing, under Section 15C; appeals lie to the National Green Tribunal on a deposit of ten per cent, under Section 15D; and receipts are credited to the Environmental Protection Fund under Section 15E. One offence survives: failure to pay a penalty within ninety days is punishable with imprisonment of up to three years, or a fine of up to twice the penalty, or both, under Section 15F.

Q: How were environmental offences punished before the Jan Vishwas amendments?

As enacted, Section 15 punished a contravention of the Act, its rules, orders or directions with imprisonment for a term which could extend to five years, or with a fine which could extend to one lakh rupees, or with both. If the contravention continued after conviction, an additional fine of up to five thousand rupees could be imposed for every day of continuance, and if it continued beyond one year after the date of conviction, the imprisonment could extend to seven years. Prosecution required a complaint through Section 19 and trial before a magistrate, with proof beyond reasonable doubt. Sections 16 and 17 supplied the liability rules for companies and government departments. The scheme’s critics in the decriminalisation debates pointed to the distance between the severity on paper and the small number of prosecutions the machinery produced.

Q: What happens when a government department violates the Act?

Section 15B, inserted by the Jan Vishwas amendments, prices the default personally and in salary rather than in the department’s budget. Where a contravention is committed by a government department, the Head of the Department is liable to pay a penalty equal to one month’s basic salary, unless it is proved that the contravention took place without the Head’s knowledge or that the Head exercised all due diligence to prevent it. Where the contravention is attributable to the neglect of an officer other than the Head, that officer is likewise liable to a penalty equal to one month’s basic salary, subject to a due diligence defence. The provision replaced the original Section 17, under which the Head was deemed guilty of an offence on the same pattern as company officers. The penalty is imposed by an adjudicating officer after inquiry, with an appeal to the National Green Tribunal.

Q: Who is liable when a company pollutes under environmental law?

Liability operates at several levels. The company itself is liable to penalty under Section 15A of this Act, of not less than one lakh rupees and up to fifteen lakh rupees, with an additional one lakh rupees for every day a contravention continues; before the Jan Vishwas substitution, Section 16 deemed the person in charge of the company’s business guilty of the offence unless it was proved the offence occurred without that person’s knowledge or despite all due diligence, and reached directors, managers and other officers with whose consent or connivance the offence was committed or to whose neglect it was attributable. Independently of penalty, a polluting company faces closure and utility stoppage directions under Section 5, environmental compensation levied by the boards and the National Green Tribunal on the polluter pays principle, consent sanctions under the Water and Air Acts, and, if it fails to pay a penalty within ninety days, prosecution under Section 15F, in which the persons in charge are deemed guilty subject to the knowledge and diligence defence.

Q: What is the Environmental Protection Fund and where does its money go?

The Environmental Protection Fund is the fund established under the new Chapter IIIA of the Act, inserted by the Jan Vishwas amendments, to receive the penalties the new adjudication system produces. Section 15E directs that penalties imposed under this Act are credited to the Fund, and the scheme extends to penalties under the Air Act, 1981. The Fund’s objects are the promotion of awareness, education and research for the protection of the environment and the advancement of the objects of the two Acts, and seventy-five per cent of the penalty amounts are allocated to the state governments, which carry most of the enforcement burden. The Environmental (Protection) Fund Rules, 2026 govern its administration, including its custody in the Public Account of India and reporting through the Central Pollution Control Board, converting what were once fines paid into general revenues into money earmarked for environmental purposes.

Q: Why was the Environment (Protection) Act enacted under Article 253 of the Constitution?

The Act’s preamble states its purpose: to implement the decisions taken at the United Nations Conference on the Human Environment at Stockholm in June 1972, in which India participated. Article 253 empowers Parliament to make laws for implementing decisions of international conferences notwithstanding the distribution of legislative powers in the Seventh Schedule. The route mattered because the environment crosses the federal lists: water, land and public health are predominantly state subjects, and a general pollution statute built on the ordinary entries would have fragmented at state borders and invited repugnancy disputes. Enacted under Article 253, the Act applies across the whole of India on subjects that would otherwise lie largely with the states, which is the constitutional foundation of the single national framework of standards, clearances and rules described in this article. The Air Act of 1981 had used the same route for its medium.

Q: What parliamentary control exists over rules and notifications made under the Act?

The control Parliament retained is the laying requirement in Section 26. Every rule made under the Act, and every notification of the kind the section specifies, must be laid before each House of Parliament for a total period of thirty days, and if both Houses agree to modify or annul the instrument, it takes effect as modified or ceases to have effect, without prejudice to the validity of anything previously done under it. In practice annulment is a dead letter, instruments are laid in bulk, and the parliamentary committees on subordinate legislation examine only a selection of the Union’s output, advising rather than deciding. The effective checks on the delegated system have therefore been the draft objection procedures that the Environment (Protection) Rules impose for restrictive instruments, which produced the mass response to the draft notification of 2020, and judicial review of particular notifications, of which the post facto clearance litigation is the leading example.

Q: What is the Coastal Regulation Zone notification?

The Coastal Regulation Zone notification is the instrument, issued under Section 3 of this Act, that regulates construction and industry along India’s coastline. The first notification, of February 1991, declared the coastal stretches influenced by tidal action, up to five hundred metres from the high tide line on the landward side, to be a coastal regulation zone, divided it into categories from the ecologically sensitive CRZ-I through built-up CRZ-II and rural CRZ-III to the water area in CRZ-IV, and prohibited or restricted classes of activity by category, with a no-development zone nearest the water. It was replaced in 2011 and again on 18 January 2019. The 2019 notification split CRZ-III by population density on the 2011 Census, reducing the no-development zone to fifty metres in the denser CRZ-IIIA areas while keeping two hundred metres in CRZ-IIIB, fixed twenty metres for specified islands, and moved clearance for CRZ-II and CRZ-III projects to the state level.
