Crusher plants in Delhi NCR have long been a subject of environmental concern and regulatory scrutiny due to their impact on air quality, noise pollution, and land use in the rapidly urbanizing National Capital Region. These plants, which process raw stone, gravel, and minerals into construction-grade aggregates, are essential for infrastructure development but have faced increasing restrictions in recent years.
Historically, several crusher and stone-crushing units operated across the Delhi-NCR, particularly in areas such as Faridabad, Gurugram, Noida, and neighboring parts of Uttar Pradesh and Rajasthan. According to the Central Pollution Control Board (CPCB) and the Delhi Pollution Control Committee (DPCC), stone crushers are classified as a red-category industry—indicating high pollution potential—requiring strict environmental clearances under the Environment (Protection) Act, 1986.
In response to deteriorating air quality in Delhi, especially during winter months, the Supreme Court of India and the Environment Pollution (Prevention and Control) Authority (EPCA) have directed the closure or relocation of non-compliant crusher plants. A 2018 EPCA report highlighted that 378 stone crushers in Haryana, Uttar Pradesh, and Rajasthan within the NCR were operating without proper consent or in violation of zoning regulations. As a result, state pollution control boards intensified enforcement, leading to the shutdown of numerous illegal units..jpg)
The National Green Tribunal (NGT) has also intervened multiple times. In a 2020 order, the NGT banned stone crushing within 5 km of any residential area or green belt in the NCR and mandated that all operational plants install pollution control devices such as water sprayers, dust suppression systems, and enclosed conveyor belts. Additionally, the use of dry screening and crushing methods was prohibited to reduce particulate emissions..jpg)
Today, only a limited number of crusher plants remain operational in the Delhi-NCR, and most are located on the periphery, such as in the Charkhi Dadri and Mahendragarh districts of Haryana or in districts of western Uttar Pradesh like Bulandshahr and Gautam Buddh Nagar—areas designated under industrial zoning with environmental safeguards.
To operate legally, crusher units must obtain Consent to Establish (CTE) and Consent to Operate (CTO) from respective State Pollution Control Boards (SPCBs), comply with emission standards under the 2003 norms for stone crushers, and adhere to the Ministry of Environment, Forest and Climate Change (MoEFCC) guidelines on industrial location.
Despite regulatory efforts, illegal or non-compliant operations occasionally resurface, often reported by local residents or environmental watchdogs. In 2022, the Haryana State Pollution Control Board (HSPCB) shut down over 40 unauthorized crushers in the Aravalli foothills near Gurugram due to violations of forest and environmental laws.
In conclusion, while crusher plants are vital for Delhi NCR’s construction industry, their operation is tightly regulated due to environmental concerns. Current policy emphasizes relocation to designated industrial zones, strict enforcement of pollution control measures, and periodic monitoring by pollution control agencies to balance development with ecological sustainability.
