The Public Liability Insurance Act, 1991 (Act 6 of 1991) is India's no-fault relief statute for victims of hazardous-substance accidents. Any occupier — factory, warehouse, pipeline or transporter — handling a notified hazardous substance above its threshold quantity must carry a PLI policy of at least paid-up capital and up to ₹50 crore, pay an equal contribution to the Environmental Relief Fund, and accept that victims can recover Schedule amounts (₹25,000 fatal, ₹12,500 medical, ₹6,000 property) from the District Collector without proving fault.
TL;DR for occupiers / founders. If your site handles a hazardous chemical above its Schedule-3 threshold under the PLI Act S.O. 227(E) notification (or any quantity listed in MSIHC Rules 1989 Schedules 2 or 3), you must hold PLI cover before handling starts. Minimum cover = your paid-up capital. Maximum = ₹50 crore. You pay an additional ERF contribution equal to the premium. Failure = 1.5 to 6 years' imprisonment plus ₹1 lakh minimum fine under Section 14. Victims file with the District Collector in Form I within 5 years; the Collector awards Schedule relief without any fault inquiry. This is a minimum-floor regime — tort and environmental-compensation claims run in parallel, only reduced pro tanto by PLI relief paid.
Why the Act exists — absolute liability made bankable
The Act was the direct legislative response to the Bhopal Gas Disaster of December 1984 and the Supreme Court's subsequent formulation of absolute liability in M.C. Mehta v. Union of India (the Oleum Gas Leak Case), AIR 1987 SC 1086. Justice P.N. Bhagwati's Constitution Bench held that an enterprise engaged in a hazardous or inherently dangerous activity owes an absolute and non-delegable duty to the community to ensure no harm results — defences available under strict liability in Rylands v. Fletcher (1868) were expressly rejected.
The doctrinal breakthrough had a practical weakness: absolute liability was a rule of common law, enforced case-by-case through writ or tort litigation, often after decades of delay (the Bhopal claim ran for over two decades). Parliament introduced the PLI Bill in 1991 to make absolute liability bankable — by compelling industry to pre-fund compensation through mandatory insurance, and by installing a summary adjudicator (the Collector) empowered to pay Schedule amounts within three months of application. Amendment Act 11 of 1992 (effective 31 January 1992) added the Environmental Relief Fund, raised the insurance cover ceiling to ₹50 crore, and introduced insurer remittance obligations.
Scope — who is an "owner" of a "hazardous substance"?
Three definitions drive the Act's scope, each tightly coupled to Section 4's insurance obligation.
"Hazardous substance" — Section 2(d)
A substance is covered only if it satisfies both limbs of Section 2(d): it is a hazardous substance under Section 2(e) of the Environment (Protection) Act, 1986, and it is handled in a quantity at or above the threshold specified by the Central Government under notification. The operative threshold notification is S.O. 227(E) dated 24 March 1992 (as corrected by S.O. 283(E) of 29 April 1993), which lists chemicals and column-3 threshold quantities. In practice, the threshold list mirrors the MSIHC Rules 1989 Schedule 2 (isolated storage) and Schedule 3 (industrial activity) quantities, so any Major Accident Hazard (MAH) installation under MSIHC Rule 2(ja) automatically falls within the PLI Act.
"Owner" — Section 2(g)
Owner means a person who owns, or has control over handling, a hazardous substance at the time of the accident. The statutory piercing — inserted by Act 11 of 1992 — reaches:
- in a firm, any partner;
- in an association, any member;
- in a company, any director, manager, secretary or other officer who is directly in charge of and responsible to the company for the conduct of its business.
Section 16 reinforces this: where the offence is committed by a company, every person in charge is deemed guilty unless he proves absence of knowledge or due diligence. Section 17 extends identical vicarious liability to Heads of Government Departments.
"Handling" — Section 2(c)
Handling in relation to any hazardous substance includes manufacture, processing, treatment, package, storage, transportation by vehicle, use, collection, destruction, conversion, offering for sale, or transfer. The sweep is deliberate: a logistics contractor moving caustic soda by road is as much an "owner" for that consignment as the upstream manufacturer. Pipelines and isolated storage sites are separately covered under the MSIHC framework and flow into the PLI Act through Section 2(d).
Mandatory insurance — Section 4
Section 4(1) is the Act's operative duty: every owner must take out one or more insurance policies against Section 3 liability before handling starts. The proviso required pre-1991 owners to procure cover within one year of commencement (i.e., by 31 March 1992). Section 4(2) requires renewal so the policy remains in force continuously.
Cover limits — Section 4(2A). Insurance cover cannot be less than the owner's paid-up capital of the undertaking handling the hazardous substance, and cannot exceed such amount (not exceeding ₹50 crore) as may be prescribed. For a non-company owner, "paid-up capital" means the market value of all assets and stocks of the undertaking on the date of the insurance contract. Rule 10 of the Public Liability Insurance Rules, 1991 caps the insurer's aggregate liability per accident at ₹5 crore and per policy year at ₹15 crore; any award exceeding policy limits is first met from the ERF and then from the owner.
ERF contribution — Section 4(2C) & (2D). The owner pays the insurer an additional sum, not exceeding the premium, which the insurer must then remit to the authority notified under Section 7A (now the CPCB, since 1 January 2025). Failure to remit converts the ERF contribution into an arrears-of-land-revenue recovery.
Exemption — Section 4(3). The Central Government may exempt the Union, a State, a Central/State PSU, or a local authority — but only if that owner maintains a substitute relief fund. Private industry has no route to exemption.
Schedule relief — the no-fault minima
The Schedule to the Act (read with Section 3(1)) fixes the Collector's maximum award per victim per head. The Schedule has not been revised since 1991, a long-standing criticism of the regime:
| Head of relief | Maximum amount | Key conditions |
|---|---|---|
| Medical expenses (all cases) | ₹12,500 per case | Reimbursement of documented expenses |
| Fatal accident | ₹25,000 per victim (plus medical up to ₹12,500) | Paid to legal representatives |
| Permanent total disability | ₹25,000 plus medical up to ₹12,500 | Certified by an authorised physician |
| Permanent partial disability / injury / sickness | Cash relief on % disablement, plus medical up to ₹12,500 | Physician certification |
| Temporary partial disability (loss of wages) | ₹1,000 per month, maximum 3 months | Hospitalisation > 3 days; victim aged 16+ |
| Damage to private property | ₹6,000 per claim | Depending on actual damage |
The Collector may award the full Schedule amount without any inquiry into fault. Section 3(2) expressly relieves the claimant of pleading or establishing wrongful act, neglect, or default. The only statutory defences available to the owner are the exclusions in the Section 2(a) definition of "accident": war and radio-activity. The force majeure carve-out for Acts of God is narrowly framed — an event must be "fortuitous or sudden or unintended" while handling the substance, and jurisprudence (drawing on M.C. Mehta) treats even rare natural triggers as foreseeable when a hazardous activity is being carried on.
Verbatim Schedule text, together with Rule 10 aggregate caps and the Form I relief application structure, is carried in the corpus counterpart.
Claim procedure — Sections 5, 6, 7
Section 5 — Collector's suo motu duty. Whenever an accident comes to the Collector's notice, the Collector must verify and publicise it (typically through district notice boards, the district gazette, and local newspapers) to invite applications. This duty is triggered independently of any claimant filing — it is the principal mechanism by which the Act reaches victims who may not know of the right.
Section 6 — Application. The claimant, legal representative, or authorised agent files in Form I (prescribed under Rule 4 of the PLI Rules 1991) with the Collector who has territorial jurisdiction over the accident. Documents annexed under Rule 4 include a physician's disability certificate, death certificate/post-mortem report, employer's wage-loss certificate, and age proof. Limitation: 5 years from the date of the accident under Section 6(3). Where multiple legal representatives exist, non-joining representatives must be impleaded as respondents.
Section 7 — Award. After notice to the owner and an opportunity to be heard, the Collector holds a summary inquiry (Section 7(4)) and makes an award in Form II. The Collector enjoys full Civil Court powers of evidence on oath and production of documents (Section 7(5)). The insurer must deposit the awarded amount within 30 days (Section 7(3)(a)); the ERF top-up follows the scheme (Section 7(3)(b)); any residue falls on the owner (Section 7(3)(c)). Non-deposit is recoverable as arrears of land revenue (Section 7(6)). Disposal target: three months from receipt of the application (Section 7(7)). Section 7(8) empowers the Collector to grant a temporary injunction under Order XXXIX CPC if the owner is likely to dispose of assets to evade payment.
Environmental Relief Fund — Section 7A
Section 7A, inserted by Act 11 of 1992, empowers the Central Government to establish the Environmental Relief Fund. The Environment Relief Fund Scheme, 2008 (G.S.R. 768(E) dated 4 November 2008) operationalised the Fund under MoEF&CC. Until 31 December 2024, the Fund Manager was United India Insurance Company Limited (UIICL), which held the corpus in fixed deposits across 13 banks. As of 31 March 2023, the corpus stood at approximately ₹1,062 crore, having grown from ₹283 crore in November 2008.
The Environment Relief Fund (Amendment) Scheme, 2024, notified December 2024, transferred administration to the Central Pollution Control Board (CPCB) with effect from 1 January 2025 for a renewable five-year term. The amendment added:
- new paragraph 7A enabling ERF use for environmental restoration (not only victim relief), with restoration plans drafted by CPCB/SPCBs and approved by the Central Government;
- a 30-day release timeline after a Collector or Central Government order;
- mandatory independent audit by an auditor appointed from a CAG-approved panel;
- additional sources including NGT Section 24 compensation and Section 14/15/17 PLI Act penalties;
- a digital portal for scheme implementation and fund tracking.
For practitioners advising on breach-of-duty claims, this expansion is material: ERF monies can now fund polluter-pays restoration awards under the NGT framework, reducing — but not eliminating — the relief pressure on the underlying PLI cover.
Powers of inspection and direction — Sections 9–13
- Section 9: Central Government-authorised officers may require any owner to submit compliance information.
- Section 10: Power of entry and inspection at any premises where a hazardous substance is handled, at all reasonable times.
- Section 11: Power of search and seizure on reasonable belief of Section 4(1) contravention; seizure can extend to the hazardous substance itself, which may be disposed of immediately if necessary to prevent an accident.
- Section 12: Power to direct prohibition or regulation of handling, or stoppage of electricity, water, or other services to the owner.
- Section 13: The Central Government may apply to a Metropolitan Magistrate or Judicial Magistrate First Class for a restraining order against an owner handling in contravention of the Act.
Under S.O. 779(E) and S.O. 780(E), both dated 15 November 1991, the Central Government delegated Sections 9–12 to State Governments and (for Section 9–11 nationally) to the Central Pollution Control Board. The practical effect is that state-level inspectors — typically the State PCB Member Secretary or designated officers — exercise most day-to-day compliance oversight.
Penalties — Sections 14–16
- Section 14(1): Contravention of Section 4(1), (2), (2A), or (2C) — i.e., failing to take out, renew, or adequately fund a PLI policy, or failing to pay the ERF contribution — or failure to comply with a Section 12 direction carries imprisonment of 1.5 to 6 years or fine of not less than ₹1 lakh, or both.
- Section 14(2): Second or subsequent convictions attract 2 to 7 years' imprisonment with a minimum ₹1 lakh fine.
- Section 14(3): The probation reliefs under Section 360 CrPC (now Section 401 BNSS, 2023) and the Probation of Offenders Act, 1958 do not apply unless the offender is under 18.
- Section 15: Obstruction of Section 10/11 inspections or non-compliance with Section 9/11 orders attracts up to 3 months' imprisonment or fine up to ₹10,000, or both.
- Section 16: Corporate vicarious liability — every person in charge of the business at the time of the offence is deemed guilty; a director/manager/secretary/officer is also personally liable where the offence is attributable to his consent, connivance, or neglect.
- Section 17: Heads of Government Departments are personally liable for departmental offences, subject to a due-diligence defence.
- Section 18: Cognizance only on complaint by the Central Government (or its authorised officer) or by any person who has given 60 days' prior notice of the alleged offence.
Interaction with the MSIHC Rules 1989 and the E(P) Act 1986
The PLI Act and the MSIHC Rules 1989 operate as a tightly coupled pair. Any site that is an MAH installation under MSIHC Rule 2(ja) (handling of hazardous chemicals at or above Schedule 2/3 threshold quantities) is, by Section 2(d), covered by the PLI Act. In a typical compliance audit, the sequence runs:
- Classification under MSIHC Schedule 1 (Part I criteria + Part II list) — is the chemical hazardous?
- Threshold check against MSIHC Schedule 2 (isolated storage) or Schedule 3 (industrial activity) — is the handled quantity at or above threshold?
- If yes → the site is an MAH under Rule 2(ja); PLI Act cover is mandatory.
- Section 41B Factories Act 1948 notification to the Chief Inspector of Factories follows for factories handling a notified hazardous process.
- Form 1 on-site emergency plan (MSIHC Rule 13), District Crisis Group notification under EPPR 2005, and Environment (Protection) Act 1986 consent to operate close the compliance loop.
Where an accident actually occurs, Section 8(1) of the PLI Act expressly preserves all other compensation rights — NGT applications under Sections 15, 17, and 24 of the NGT Act, 2010; writ relief invoking absolute liability under M.C. Mehta; and common-law tort suits. Section 8(2) operates as a set-off: if the owner is liable to pay under any other law, that liability is reduced by the PLI relief already paid.
State variations — Collector jurisdiction and State PCB delegation
Gujarat
Collector jurisdiction is district-based under the Gujarat Collector (Powers and Duties) framework. The Gujarat Pollution Control Board (gpcb.gujarat.gov.in) exercises delegated Section 9–11 powers. Major industrial belts — Dahej, Ankleshwar, Vapi, Hazira — have standing District Crisis Group protocols linking the Collector, GPCB, and DISH Gujarat. Form I applications are filed at the District Collectorate in physical form; online filing is not yet available.
Maharashtra
Mumbai Suburban, Thane, Raigad, and Pune Collectors have the largest PLI Act caseloads given the Trombay–Taloja–Patalganga–Mahad chemical belts. The Maharashtra Pollution Control Board (mpcb.gov.in) exercises delegated powers. DISH Maharashtra (mahadish.in) maintains the MAH-site register and shares accident data with the Collector under mutual SOPs, though the statutory nexus runs through the Collector under the PLI Act.
Tamil Nadu
Chennai, Kancheepuram, Thoothukudi, Cuddalore, and Coimbatore Collectors handle most applications. The Tamil Nadu Pollution Control Board (tnpcb.gov.in) is the delegated Section 9–11 authority. The Cuddalore SIPCOT belt (notorious for its MAH density) and the Manali petrochemical complex dominate the district workload; Thoothukudi remains the high-profile post-Sterlite jurisdiction.
Karnataka
Bengaluru Urban, Bengaluru Rural, Tumakuru, and Mangaluru Collectors are the principal adjudicators. The Karnataka State Pollution Control Board (kspcb.karnataka.gov.in) exercises delegated powers. Accident workload is concentrated around the Mangaluru Special Economic Zone (MRPL, MCF, ONGC) and the Tumakuru/Harohalli industrial belts.
Delhi
The Deputy Commissioner of the relevant district exercises Collector functions under PLI Act Section 5. Given the NCT's limited heavy-chemical footprint, PLI Act filings are rare; the Delhi Pollution Control Committee (dpcc.delhi.gov.in) exercises delegated Section 9–11 powers, chiefly for warehousing and transport sites.
Other states
In every State, the officer designated as Collector under the Code of Civil Procedure / state revenue code exercises PLI Act Section 5–7 functions, and the State Pollution Control Board exercises the Central Government's delegated Section 9–11 powers under S.O. 780(E) of 15 November 1991.
Occupier / founder checklist
- Map your hazardous-substance inventory against MSIHC Schedule 1/2/3 and S.O. 227(E). Any chemical at or above threshold triggers PLI Act Section 4(1).
- Procure PLI cover BEFORE handling starts — a policy equal to at least your paid-up capital, up to ₹50 crore. Record the sum insured against the MSIHC threshold test and renew continuously.
- Pay the ERF contribution (up to 1× premium) alongside the premium; retain the insurer's ERF remittance certificate. Post 1 January 2025, the remittance flows to CPCB.
- File Section 41B Factories Act and Form 1 MSIHC on-site emergency plan — both are compliance anchors that a Collector will request in a Section 7 inquiry.
- Board-minute the PLI cover and record director-level responsibility — Section 16 personal liability attaches on default.
OSH Code transition note
The PLI Act 1991 sits under MoEF&CC and is not subsumed by the Occupational Safety, Health and Working Conditions Code, 2020. The OSH Code consolidates labour-safety statutes (Factories Act 1948, BOCW Act 1996, Contract Labour Act 1970, ISMW Act 1979, etc.); the PLI Act is a Public Liability statute under the Environment (Protection) Act, 1986 rule-making framework. Its ERF, Collector-adjudicated relief regime, and MSIHC-threshold trigger remain untouched by OSH Code commencement. Practitioners advising on chemical-site safety must therefore maintain parallel compliance tracks — one under the OSH Code/Factories Act and one under PLI-MSIHC-HW Rules-EPPR under MoEF&CC.
