The Central Pollution Control Board (CPCB) has laid down specific guidelines and standards to control dust emissions from stone crusher units, which are a significant source of particulate matter (PM10 & PM2.5). Below are the key measures and regulatory frameworks for dust control:<\/p>\n
1. CPCB Guidelines for Stone Crushers
\n– Siting Criteria: Stone crushers should be located at least 500 meters away from human habitation and sensitive areas (schools, hospitals, water bodies).
\n– Emission Standards:
\n – Particulate Matter (PM) emissions should not exceed 150 \u00b5g\/m\u00b3 (24-hour average) as per CPCB norms.
\n – Fugitive emissions must be controlled through enclosures, water sprinkling, and dust suppression systems.<\/p>\n
2. Dust Control Measures
\n# (A) Primary Control Measures
\n– Water Sprinkling System: Regular spraying of water on raw materials, crushing zones, and conveyor belts to suppress dust.
\n– Enclosures & Covering: Crushers, screens, and conveyors should be fully covered to prevent fugitive dust.
\n– Green Belt Development: Planting trees around the unit acts as a natural dust barrier.<\/p>\n
# (B) Secondary Control Measures
\n– Bag Filters\/Ventilation Systems: Installation of high-efficiency bag filters to capture fine particles.
\n– Wet Dust Suppression Systems: Using mist cannons or fogging systems near crushing points.
\n– Road & Transport Management: Paved roads with water sprinklers to minimize dust from vehicle movement.<\/p>\n
3. Legal Compliance
\n– Stone crushers must obtain Consent to Establish (CTE) & Consent to Operate (CTO) under the *Air (Prevention & Control of Pollution) Act, 1981*.
\n– Compliance with the *Environment Protection Rules* and state-specific pollution control board norms is mandatory.<\/p>\n
4. Monitoring & Reporting
\n– Regular monitoring of ambient air quality using PM10\/PM2.5 samplers.
\n– Submission of half-yearly compliance reports to SPCB\/CPCB.<\/p>\n
5. Penalties for Non-Compliance
\n– Heavy fines under the *Environment (Protection) Act, 1986*.
\n– Shutdown orders if violations persist.<\/p>\n
Conclusion
\nEffective dust control in stone crushers requires a combination of engineering controls (water sprays, enclosures), administrative measures (regular monitoring), and green solutions (tree plantation).
