With an environmental public hearing coming up in the state on January 24, Vedanta- Goa on Wednesday said that it is committed to growth and sustainable development through its proposed projects involving expansion of capacity and new product lines at Amona and Navelim.

The company said that, the projects have the potential to create additional local employment and could significantly contribute to the state revenue.

Referring to local groups opposing the projects on environment concerns and other statutory compliances, the company clarified that, all its existing plant operations are being carried out within the norms as prescribed by various statutory and executive authorities.

“The blast furnace expansion in 2012 got clearance after MOEF re-evaluated stipulated EC conditions based on NGT’s directives and there is no stay or any order with punitive action.   Even the Navelim land acquired by GIDC (for the company) is part of the Bicholim IDC and all official correspondence is being done from Bicholim IDC,” said Vedanta.

The company maintained that, all the emissions from the existing operations are within statutory norms and all the de-dusting and suppression systems are functioning at optimum level. Further it is progressively working towards controlling fugitive emissions at minute levels.

“The oxygen required in the process is extracted from the existing oxygen and nitrogen plant at the premises which produces 100 TPD oxygen and 50 TPD nitrogen. Oxygen and nitrogen are generated by separating them from air in a scientific process using distillation method without having any effect on the oxygen levels in the air,” explained Vedanta.

It said that, all the company’s water and air management systems are in line with the conditions prescribed under consent to operate from the GSPCB. Further it is “aggressively investing in dust extraction systems, road sweeping machines, rain guns and fog guns and dust suppressions systems etc., to ensure reduction in fugitive emissions.”

The public hearing on January 24, is at the village playground, Navelim, near Vividha Higher Secondary School, from 10.30 am till 7 pm.

The project involves expansion of blast furnace (BF) capacity, BF 1&2 from 2,92,000 TPA to 3,50,000 TPA, BF-3 from 5,40,000 TPA to 6,50,000 TPA, setting up of additional oxygen plant, a ductile iron pipe plant of 3 lakh TPA capacity, additional met coke ovens and Fe-Si plant of 5,000 TPA.

The company said that capacity expansion of the BF will be through efficiency improvement methods such as increase in sinter percentage, improving OEE, increasing wind volume and better grade of iron ore and oxygen enrichment.

The Vedanta pig iron plant at Amona is India’s largest merchant producer of low phosphorous pig iron in India with an installed capacity of 832000 MT annually. The company also has two power plants in the site that produces 56-58 MW of power by using the waste heat from its coke ovens and gases from BF. The power plant gives 50 per cent of its production to the state grid.
