The Meghalaya State Pollution Control Board has issued a public notice fixing January 22 next year for a public hearing for the expansion project at the mines premises at Nongtrai.
"The company has expressed its desire to scale up production and export of limestone from our mines at Nongtrai, doubling from the current two MTPA to five MTPA," a senior official of the company told PTI on condition of anonymity.
The Company had applied for environmental clearance from the Union Ministry of Environment, Forests and Climate Change in 2009 in this regard, the official said adding, a summary environmental impact assessment report of the new project has also been released.
At present the parent company, Lafarge Umiam Mining Pvt Ltd, exports two million tonnes of limestone mined from 100 ha at Nongtrai to its cement factory at Chattak in Bangladesh through a 17 km-long cross-border conveyor belt.
The Lafarge Surma Cement Ltd, the holding company of Lafarge Umiam Mining, is one of the largest publicly traded firms in Bangladesh.
