Regulation of Chemicals and Waste Management in India

Chemical regulation and waste management in India operate under umbrella environmental legislations designed to prevent industrial pollution, manage toxic hazards, and enforce circular economy principles. The legal architecture assigns responsibilities across central ministries, state pollution control boards, municipal bodies, and industrial producers through targeted rules. These frameworks govern hazardous industrial chemicals, plastic waste, electronic waste, biomedical residue, and municipal solid wastes.

Statutory and Constitutional Framework

India’s environmental protection statutes establish statutory bodies and regulatory authorities to enforce chemical safety and waste rules.

Foundational Environmental Laws

• The Environment (Protection) Act, 1986 (EPA): Serves as the principal umbrella legislation enacted under Article 253 of the Constitution to implement decisions of the 1972 Stockholm Conference.
• The Water (Prevention and Control of Pollution) Act, 1974: Created the Central Pollution Control Board (CPCB) and State Pollution Control Boards (SPCBs) to regulate industrial effluent discharges.
• The Air (Prevention and Control of Pollution) Act, 1981: Regulates gaseous industrial emissions, chemical fumes, and ambient air standards.
• The Public Liability Insurance Act, 1991: Mandates compulsory insurance for industries handling specified hazardous substances to provide immediate relief to accident victims on a no-fault liability basis.
• The National Green Tribunal Act, 2010: Established the National Green Tribunal (NGT) under Article 21 to ensure speedy disposal of civil cases involving environmental protection and statutory enforcement.

Major Waste Management Rules

The Ministry of Environment, Forest and Climate Change (MoEFCC) notified comprehensive waste management rules in 2016, revising older regulatory frameworks.

Extended Producer Responsibility (EPR) Framework

Extended Producer Responsibility shifts the end-of-life treatment costs of post-consumer products to manufacturers, brand owners, and importers.

EPR Across Waste Streams

• Plastic Packaging EPR: Classifies plastic packaging into four categories: Category I (rigid plastic), Category II (flexible plastic packaging of single or multi-layer), Category III (multi-layered plastic packaging with at least one non-plastic layer), and Category IV (plastic sheets and compostable plastic bags).
• E-Waste EPR Regime: Replaced physical collection targets with tradeable EPR certificates issued to formal recyclers by the CPCB online portal.
• Battery Waste EPR: Mandates that producers achieve 100% collection and recycling targets for spent batteries, ensuring minimum recovery percentages for cobalt, nickel, lithium, and lead.
• Used Oil EPR: Requires base oil producers and importers to register on the national portal and meet annual used oil recycling quotas.

Regulation of Hazardous Chemicals and Industrial Safety

Industrial chemical handling rules establish protocols to prevent chemical disasters like the 1984 Bhopal Gas Leak.

Chemical Safety Regulations

• Manufacture, Storage and Import of Hazardous Chemical (MSIHC) Rules, 1989: Requires industrial units storing threshold quantities of hazardous chemicals to prepare on-site and off-site emergency plans, conduct safety audits, and notify district authorities.
• Chemical Accidents (Emergency Planning, Preparedness, and Response) Rules, 1996: Establishes a four-tier institutional disaster management system: the Central Crisis Group, State Crisis Group, District Crisis Group, and Local Crisis Group.
• Draft Chemical (Management and Safety) Rules (CMSR / Indian REACH): Proposes comprehensive notification, registration, and safety data sheet (SDS) requirements for chemical substances imported or manufactured in quantities above one tonne per year.
• National Chemical Inventory: Designed to track priority chemicals, identify persistence, bioaccumulation, and toxicity (PBT) profiles, and restrict restricted substances.

Bio-Medical Waste Segregation Categories

The Bio-Medical Waste Management Rules mandate a four-colour segregation system for healthcare facilities.

International Chemical and Waste Conventions Ratified by India

India aligns domestic chemical management rules with global multilateral environmental agreements.

Global Environmental Treaties

• Basel Convention (1989): Regulates transboundary movements of hazardous wastes and their disposal to prevent illegal hazardous waste dumping in developing countries.
• Rotterdam Convention (1998): Enforces Prior Informed Consent (PIC) procedure for international trade in hazardous chemicals and pesticides.
• Stockholm Convention (2001): Mandates the elimination and phase-out of Persistent Organic Pollutants (POPs) such as aldrin, dieldrin, DDT, and polychlorinated biphenyls (PCBs).
• Minamata Convention (2013): Regulates anthropogenic emissions and releases of mercury, phasing out mercury-added products and mining processes.

Important Facts

• Section 3 of the Environment (Protection) Act, 1986 empowers the Central Government to take all measures necessary to protect environmental quality and coordinate state actions.
• The Central Pollution Control Board operates under the administrative control of the Ministry of Environment, Forest and Climate Change.
• The 2016 Solid Waste Management Rules extended regulatory jurisdiction beyond municipal boundaries to include census towns, notified industrial townships, and railway zones.
• Domestic hazardous waste under the 2016 rules includes discarded paint cans, pesticide containers, CFL bulbs, tube lights, and expired medicines.
• The Plastic Waste Management Rules prohibited the manufacture, import, stocking, distribution, sale, and use of identified single-use plastic items with low utility and high littering potential starting July 1, 2022.
• The minimum thickness of plastic carry bags was raised to 120 microns effective December 31, 2022.
• The Restriction of Hazardous Substances (RoHS) provisions in E-Waste Rules restrict lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), and polybrominated diphenyl ethers (PBDE) beyond prescribed concentrations.
• Lead-acid batteries must comply with the Battery Waste Management Rules, 2022, which superseded the Batteries (Management and Handling) Rules, 2001.
• The Central Crisis Group for chemical emergencies is headed by the Secretary, Ministry of Environment, Forest and Climate Change.
• In 2020, India banned the manufacture, trade, and use of seven hazardous persistent organic pollutants (POPs) listed under the Stockholm Convention, including Chlordecone and Hexabromobiphenyl.
• The manifest system under the Hazardous Waste Rules requires a 7-colour document chain to track hazardous waste shipments from generator to final disposal facility.
• The Supreme Court of India recognized the Precautionary Principle and the Polluter Pays Principle as essential elements of sustainable development in the Vellore Citizens’ Welfare Forum v. Union of India (1996) case.
