Environmental Impact Assessment (EIA) Notification for Stone Crusher Plants

Stone crusher plants play a crucial role in the construction and mining industries by processing raw materials into aggregates. However, their operations can significantly impact the environment, necessitating strict regulatory oversight. In India, the Environmental Impact Assessment (EIA) Notification, 2006, under the Environment (Protection) Act, 1986, mandates environmental clearance for stone crusher projects based on their capacity and location.

When Is EIA Notification Applicable?
The EIA notification categorizes stone crusher plants based on production capacity:
- Category A: Projects with a crushing capacity of ≥200 tonnes per hour (TPH) or those located within 10 km of ecologically sensitive areas require mandatory environmental clearance from the Ministry of Environment, Forest and Climate Change (MoEF&CC).
- Category B: Units with a capacity between 25 TPH and 200 TPH must obtain clearance from the State Environmental Impact Assessment Authority (SEIAA).
- Smaller units (<25 TPH) may be exempted but must still comply with local pollution control board norms.

Key Steps in Obtaining Environmental Clearance
1. Screening & Scoping: The project proponent submits a preliminary report detailing site location, production capacity, and potential environmental impacts. Authorities determine whether an EIA study is required.
2. Public Consultation: Mandatory hearings allow local communities and stakeholders to voice concerns regarding air pollution, water contamination, noise levels, and land degradation caused by crushing activities.
3. EIA Report Preparation: A detailed study assesses impacts on air quality (dust emissions), groundwater levels, biodiversity loss due to blasting/mining activities nearby forests/wetlands/riversides etc., along with mitigation measures like water sprinklers/silencers/green belts around sites etc..
4.Appraisal & Approval: Expert committees review findings before granting final approval subject to compliance conditions such as installing pollution control devices or compensatory afforestation if forest land is involved..

Compliance Requirements Post-Clearance
Operators must adhere to:
- Regular monitoring of particulate matter (PM10/PM2.5) emissions via stack testing; maintaining records submitted annually under Consent To Operate renewals issued by State Pollution Control Boards(SPCBs).
- Implementing noise barriers near residential zones; limiting operational hours where necessary per local regulations..
