The Central Pollution Control Board (CPCB), a statutory organization established in 1974 to regulate environmental pollution, has recently published guidelines for stone crushing units. This move comes as a response to the long-standing issue of air pollution caused by these units.
Origins of the Guidelines
Recognizing the growing concern over severe air pollution from stone crushing, CPCB developed these guidelines in collaboration with the New Delhi-based non-profit Centre for Science and Environment (CSE). The guidelines aim to address the destructive mining associated with stone crushing and the resulting dust emissions affecting worker health and local environments.
CPCB’s Key Recommendations for Stone Crushing Units
CPCB’s guidelines cover multiple aspects of stone crushing, including source emissions, product storage, water usage, transportation, and legal compliance. Some of the key recommendations include:
– Stone crushers should obtain establishment consent and operating consent from the State Pollution Control Board (SPCB) before beginning operations.
– Stone crushers are required to install adequate control devices to reduce dust emissions.
– Regular health surveys of workers should be carried out by stone crusher units themselves.
– A District Level Committee is to be formed under the chairmanship of the District Magistrate or Deputy Commissioner for regular inspections of stone crushing units.
The Issue with Stone Crushing Units in India
Stone crushing units in India contribute significantly to air pollution. The crushed stones produced by these units are used as raw materials in various construction activities, generating substantial dust that can impact both worker health and the surrounding environment. In December 2022, the Haryana government proposed easing proximity norms for setting up new stone crushers near residential areas, sparking backlash from environmentalists.
Action Steps against Stone Crushing Units
The Environmental Pollution (Prevention & Control) Authority banned the operation of stone crusher units under the implementation of the Graded Response Action Plan. Pune University researchers in May 2023 found that a model stone crushing unit in Pune had successfully reduced dust emissions by 90%.
Understanding The Central Pollution Control Board
The CPCB was established under the Water (Prevention and Control of Pollution) Act, 1974 and was entrusted with powers under the Air (Prevention and Control of Pollution) Act, 1981. It is the central body for environmental protection and pollution control in India, coordinating with State Pollution Control Boards and other agencies.
Shortcomings in the CPCB Guidelines
Despite covering various aspects of pollution control, the guidelines fall short in addressing noise emissions and standalone stone crusher operations during inconvenient hours. Providing specific timelines for stone crushers to adhere to the guidelines and directing SPCBs to enforce them effectively are also crucial improvements needed.
