🗞️ Why in News Reports of toxic discharges from chemical manufacturing clusters in Gujarat, Maharashtra, and Andhra Pradesh have intensified calls for stronger regulation of India’s rapidly growing chemicals sector, which contributes ~$220 billion to GDP but generates significant hazardous waste and effluent pollution.
The Editorial Argument
The Hindu editorial argues that India’s chemicals industry operates in a regulatory vacuum — the country lacks a comprehensive chemicals management law, relies on fragmented effluent standards, and suffers from chronic enforcement failures at the SPCB level. The editorial calls for a unified Chemicals Safety Act aligned with global frameworks.
India’s Chemical Industry — Scale
| Metric | Data |
|---|---|
| Global rank | 6th largest chemical producer; 3rd in Asia |
| Market size | ~$220 billion (2025); projected $300 billion by 2030 |
| Contribution to GDP | ~7% |
| Employment | ~5 million (direct and indirect) |
| Major clusters | Gujarat (Vapi, Ankleshwar), Maharashtra (Raigad, Thane), AP (Visakhapatnam), Tamil Nadu (Cuddalore) |
| Hazardous waste generated | ~7.9 million tonnes/year (CPCB 2023) |
Regulatory Framework — The Gaps
India does not have a single comprehensive chemicals management law. Regulation is spread across multiple statutes:
| Law/Rule | Scope | Gap |
|---|---|---|
| Environment Protection Act, 1986 | Umbrella environmental law; empowers rule-making | No specific chemical safety provisions |
| Hazardous and Other Wastes (Management and Transboundary Movement) Rules, 2016 | Hazardous waste handling, storage, transport, disposal | Weak enforcement; illegal dumping widespread |
| Manufacture, Storage and Import of Hazardous Chemical Rules, 1989 | On-site/off-site emergency plans | Outdated chemical list; not aligned with GHS |
| Water (Prevention and Control of Pollution) Act, 1974 | Effluent discharge standards | SPCBs understaffed; Consent to Operate (CTO) routinely issued without inspection |
| Air (Prevention and Control of Pollution) Act, 1981 | Air emission standards | Industrial emission monitoring is sporadic |
The Enforcement Deficit
- CPCB (Central Pollution Control Board) sets standards but has no direct enforcement power over industries — this lies with SPCBs (State Pollution Control Boards)
- SPCBs are chronically understaffed: national average of ~1 inspector per 500 industries
- Consent to Operate (CTO): Many SPCBs issue CTOs based on self-reported data, not independent inspection
- Online monitoring: Continuous Emission/Effluent Monitoring Systems (CEMS/CEQMS) mandated for 17 categories of grossly polluting industries, but compliance is estimated at <40%
- Penalties: Environmental fines under EPA 1986 were Rs 1 lakh (increased to Rs 5 crore under 2023 amendment) but rarely imposed
Industrial Categorisation
CPCB classifies industries into four colour categories based on pollution potential:
| Category | Pollution Index | Examples |
|---|---|---|
| Red | PI > 60 | Chemicals, petrochemicals, pharmaceuticals, dyes, pesticides |
| Orange | PI 41-59 | Food processing, textiles, auto parts |
| Green | PI 21-40 | Paper products, electrical components |
| White | PI ≤ 20 | Flour mills, ice factories, electronics assembly |
Most chemical industries fall under the Red category, requiring stricter CTO conditions, annual environmental audits, and real-time effluent monitoring.
The Planetary Boundaries Connection
The editorial invokes the planetary boundaries framework (Johan Rockstrom, Stockholm Resilience Centre, 2009): the boundary for “novel entities” (synthetic chemicals, plastics, endocrine disruptors) has been breached as of 2022. Over 350,000 synthetic chemicals are registered globally, but fewer than 5% have been assessed for environmental and health safety.
International Comparison
| Country | Chemical Safety Law | Key Feature |
|---|---|---|
| EU | REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) | Burden of proof on manufacturers; 23,000+ substances registered |
| US | Toxic Substances Control Act (TSCA, amended 2016) | EPA evaluates and restricts chemicals |
| China | Measures for Environmental Management of New Chemical Substances (Order 12) | Pre-manufacture registration required |
| India | No comprehensive chemicals law | Fragmented; no pre-manufacture safety assessment |
Policy Recommendations
- Chemicals Safety Act: Enact a unified law requiring pre-manufacture safety assessment for new chemicals — shift burden of proof from regulators to manufacturers
- National Chemical Inventory: Create a digital registry of all chemicals manufactured, imported, and used in India
- SPCB reform: Increase inspector-to-industry ratio; mandate third-party audits; digitise CTO process
- GHS alignment: Update India’s chemical classification to the Globally Harmonised System (GHS) for labelling and safety data sheets
