Note on Environmental Impact of Industrialisation in Sambalpur-Jharsuguda Region by Chairman, Orissa Pollution Control Board

The Chairman, Orissa Pollution Control Board, paints a scary scenario of the environmental impacts of the proposed industrial investments in the Sambal-Jharsuguda region in Orissa. Some quotes:
"In Jharsuguda region if all the proposed aluminium smelter capacities would be made operational the emission of fluoride will remain in the range of 250-360 kg/hr, and it would severely  affect the agriculture more frequently and the forest around the smelters may even get wiped out permanently." 
On Water situation, he has this to say "Present level of water drawl will increase 20 times to 2143 MLD...The runoff in this region is likely to be contaminated with fluoride since the smelter in this region would annually consume about 80,000 tons of fluoride bearing materials. Considering 1% spillage and related loss, about 800 tones of these materials may be washed into the reservoir. Besides 3160 tons of fluoride will be emitted through stack room and pot room emission, even when it remaining with permissible limit. Similarly, 1,26,000 tons of fluoride bearing hazardous waste would be generated in this region annually, which puts the reservoir under significant risk of fluoride contamination. Fluoride level of more than 1.5 mg/l in water is known to cause fluorosis, a deadly disease for which there is no cure, if contaminated water is consumed for a prolonged period. In areas around NALCO (whose present capacity is 10% of what is proposed in Jharsuguda) signs of dental fluorosis in bovine population have been documented. In the event, if Hirakud reservoir gets contaminated with fluoride, fluorosis may attain a dimension of epidemic in this region and beyond."
On solid waste "This means in 20 years. 13000ha. of land would be converted to waste disposal site around the Hirakud reservoir"
On Greenhouse emission and heat island effect "Thus, the ambient temperature in this region is likely to be at least 2-3 degree Celsius higher than its neighbourig countryside."
This was a two page note- conveying some bitter truth to the people of Sambalpur-Jharsuguda of what waits for them in future. Please see the note at
