International Conventions and National Acts on Chemical Safety and Pollution Control

Chemical safety and pollution control involve a multi-layered framework of global treaties, domestic statutes, and regulatory mechanisms. These legal instruments manage hazardous substances throughout their lifecycle, covering manufacturing, handling, transboundary transport, and disposal to safeguard human health and the environment from toxic exposure, industrial accidents, and persistent pollutants.

Major International Conventions on Chemical Safety

Global chemical management relies on specialized multilateral environmental agreements that regulate trade, restrict hazardous classes, and enforce prior informed consent procedures.

Basel Convention (1989)

• Adopted in Basel, Switzerland, in 1989 and came into force in 1992.
• Controls the transboundary movements of hazardous wastes and their disposal.
• Aims to protect developing countries from toxic waste dumping by developed nations.
• Mandates the Prior Informed Consent (PIC) procedure before hazardous waste export.
• Excludes radioactive waste covered by International Atomic Energy Agency (IAEA) systems.
• The 1995 Basel Ban Amendment prohibits all exports of hazardous wastes from OECD to non-OECD countries.

Rotterdam Convention (1998)

• Adopted in 1998 and entered into force in 2004.
• Establishes the Prior Informed Consent (PIC) Procedure for Certain Hazardous Chemicals and Pesticides in International Trade.
• Facilitates information exchange on hazardous chemical characteristics and national import decisions.
• Covers banned or severely restricted pesticides and industrial chemicals listed in Annex III.
• Creates Decision Guidance Documents (DGDs) shared with all member states for informed trade decisions.

Stockholm Convention (2001)

• Adopted in 2001 and came into force in 2004.
• Aims to eliminate or restrict the production and use of Persistent Organic Pollutants (POPs).
• Targets toxic chemicals that resist environmental degradation, bioaccumulate in fatty tissues, and transport across long distances.
• Classified POPs into Annex A (Elimination), Annex B (Restriction), and Annex C (Unintentional Production).
• The initial agreement targeted the “Dirty Dozen” chemicals, including DDT, Aldrin, Dieldrin, and Polychlorinated Biphenyls (PCBs).

Minamata Convention on Mercury (2013)

• Adopted in Kumamoto, Japan, in 2013 and entered into force in 2017.
• Controls anthropogenic emissions and releases of mercury and mercury compounds.
• Regulates the entire lifecycle of mercury, including primary mercury mining, trade, use in products, artisanal small-scale gold mining (ASGM), and atmospheric emissions from coal-fired power plants.
• Sets phase-out dates for mercury-added products such as batteries, switches, compact fluorescent lamps, and medical devices.

Strategic Approach to International Chemicals Management (SAICM)

• Adopted in 2006 in Dubai under the United Nations Environment Programme (UNEP).
• Acts as a non-binding global policy framework to promote chemical safety throughout their life cycle.
• Succeeded by the Global Framework on Chemicals adopted at the fifth International Conference on Chemicals Management (ICCM5) in Bonn in 2023.

Indian Legal Framework on Chemical Safety

India addresses chemical management and environmental pollution through umbrella environmental legislation supported by specialized subordinate rules.

Environment (Protection) Act, 1986

• Enacted under Article 253 of the Constitution following the Bhopal Gas Leak tragedy of 1984.
• Serves as umbrella legislation empowering the Central Government to establish environmental standards, inspect industrial units, and issue closure orders.
• Section 8 prohibits the handling of hazardous substances except in compliance with procedural safeguards.

Manufacture, Storage and Import of Hazardous Chemical (MSIHC) Rules, 1989

• Framed under the Environment (Protection) Act, 1986 to manage industrial chemical hazards.
• Requires industrial sites to identify Major Accident Hazards (MAH) based on chemical threshold quantities.
• Mandates the preparation of On-Site Emergency Plans by site occupiers and Off-Site Emergency Plans by District Crisis Groups.
• Requires safety reports, safety audits, and notification of major chemical accidents to statutory authorities within 48 hours.

Chemical Accidents (Emergency Planning, Preparedness and Response) Rules, 1996

• Sets up a four-tier institutional crisis management structure:
  • Central Crisis Group (Apex monitoring body headed by Secretary, MoEFCC).
  • State Crisis Group (Headed by the Chief Secretary).
  • District Crisis Group (Chaired by the District Collector / District Magistrate).
  • Local Crisis Group (Chaired by the Sub-Divisional Magistrate).
• Manages continuous monitoring, mock drills, and immediate response protocols for industrial chemical emergencies.

Hazardous and Other Wastes (Management and Transboundary Movement) Rules, 2016

• Regulates the generation, storage, collection, recycling, and disposal of hazardous waste streams.
• Outlines the waste management hierarchy: prevention, minimization, reuse, recycling, recovery, and safe disposal.
• Requires authorization from State Pollution Control Boards for operating Treatment, Storage, and Disposal Facilities (TSDF).
• Regulates the import and export of hazardous wastes aligned with Basel Convention obligations.

Public Liability Insurance Act, 1991

• Mandates compulsory public liability insurance for industrial units handling hazardous substances above specified threshold quantities.
• Provides immediate financial relief to victims of chemical accidents on a “No Fault Liability” basis.
• Established the Environment Relief Fund (ERF) to pay claims determined by the District Collector.

Insecticides Act, 1968

• Regulates the import, manufacture, sale, transport, distribution, and use of insecticides to prevent risks to humans and animals.
• Governed through the Central Insecticides Board (CIB) and the Registration Committee under the Ministry of Agriculture and Farmers Welfare.

Facts on Chemical Safety and Pollution Control

• The Minamata Convention is named after Minamata City in Japan, where industrial discharge of methylmercury into Minamata Bay caused severe neurological disease in the mid-twentieth century.
• The Basel, Rotterdam, and Stockholm conventions operate through a joint Secretariat based in Geneva to streamline administrative functions and technical support.
• Persistent Organic Pollutants possess four key properties: toxicity, persistence, bioaccumulation, and long-range environmental transport.
• The Environment (Protection) Act, 1986 gives effect to the decisions taken at the United Nations Conference on the Human Environment held in Stockholm in 1972.
• The Central Pollution Control Board (CPCB) and State Pollution Control Boards (SPCBs) exercise regulatory authority over chemical waste under the Hazardous Waste Rules, 2016.
• India has completely banned seven of the initial twelve POPs under the Stockholm Convention, including Aldrin, Chlordane, Dieldrin, Endrin, Heptachlor, Hexachlorobenzene, and Toxaphene.
• The National Disaster Management Authority (NDMA) issues national guidelines for chemical disaster management and off-site emergency plans.
• The Globally Harmonized System of Classification and Labelling of Chemicals (GHS) is a United Nations standard that provides universal criteria for classifying chemical physical, health, and environmental hazards.
• In India, compensation claims for environmental damage and personal injury resulting from hazardous chemical accidents can be filed before the National Green Tribunal (NGT) under the NGT Act, 2010.
• Polychlorinated Biphenyls (PCBs) were historically used as dielectric fluids in electrical transformers and capacitors, and are slated for global phase-out under the Stockholm Convention.
